Description of which the following is a specification; `UNITED STATns PATENT OFFICE. MILTON BRADLEY, OF SPRINGFIELD, MASSACHUSETTS.` COMPASSES.V SPECIFICATION forming part of Letters Patent No. 524,160, dated August 7, 1894. . Application filed April 11, 1894. To alwhom tm/ty concern.- Be it known that I, MILTON BRADLEY, a siding at Springfield, in the county o'f Hampden and State of Massachusetts, haveinvented new and useful Improvements in Compasses, This invention relates to compasses for the j e use of draftsmen and students, the object be- .e IS ing to improve the construction of such instruments in respect to the leg-joint thereof, to means on one of the-legs for holding and Operating a pencil and to means for `uniting a steel point to the other leg, all as hereinafter fully set forth. In the drawings forming part of this speciication, Figure l isa perspective view of a pair of Compasses Vembodying my improvements, a pencil being there shown connected to one of the legs thereof. Fig. 2 illustrates, . vin perspective views, the handle and the jointpin and `nut of the instrument, and the spanner for turning said nut. Figs. 3 and 4 are perspective views of the'upper ends of the two legs ofthe compasses, illustrating the joint formation of each leg. Fig. 5`is a longitudinal section of the lower end of the peni cil-carrying leg. Fig. `6 is a side view of the e lower end of said last named leg, showing the V3,0 front side of the pencil tube broken away at Yits lower extremity. Fig. 7 is an end view of l the pencil-tube and a cross sectional view of the leg'thereto connected. Figs. 8 and 9 are y sectional views about on line 9 9, Fig. 1, of 35 the point-bearing leg, illustrating the` manner of securing the point rigidly in the leg. In the drawings, 2 indicates the point-bearing leg, and Sthe pencil-bearing leg of the instrument. The 4joint-parts of said legs are constructed as follows: 0n the upperl end of one leg, 2, for instance, is a circular, platelike formation, a, havingthe kcentral bolthole, b, and the concentric vupstanding ring, c, on the inner side of said plate, located about-'midway between the border and the center of the latter. On the upper end of the opposite leg of the instrument, 3, is a similar circular plate, cl, having` also a central bolt-hole, e, corresponding to said hole, b, of the leg, 2, and having a concentric circular groove, f, in its inner face of such width, diameter, and depth, as adapts it to receive sition. Serial No. 507,087. `(No model.) . therein the said projecting ring, c, of the leg, 'i ring and said groove are brought into j uxtapo- The said ring, c, and groove, f, are formed with most-carefully adjusted tools, to the end that the ring shall f it perfectly into the groove, thus bringing the said inner surfaces of the plates, a and d, so that they bear one against the other, and, together with the said interengagement of the ring, c and the groove, f, constitute such a wide bearing for the joint parts of the compass legs that great durability of the joint is secured, and there y,is no tendency to looseness and consequent inadvertent displacement `of the `legs when adjusted to certain relative positions of spread', and whilebeing used. . The handle, K, of the instrumen-t consists. y of a metallic tube, 4., to which` are secured two metal disks, 5, each havinga laterally extending arm, 6, on its border which enters and is secured to the inner surfaceof 4the' tube, K, by solderingor other vsuitable means. The said disks are perforated to correspond with said bolt-holes, b and e, of the joint parts i -of the compasses As shown in Fig. 1, the head (or united joint parts) of `the instrument is claspedbetween said disks, 5,and a joint-bolt, 7,'.Whose diameter is less than that of said bolt-holes, 8. Said bolt, 7,'is made to fit loosely in said bolt-holes so that it may act together with Y said nut, simply to prevent any separation of" the surfaces of said joint-parts onwhich are the said interlocking ring, c, and groove, f; and so that said bolt shall not exercise any 1 function of an ordinary j oint-pivot, and thereby prove an obstacle to the proper free coac-A tion of said grooves of the joint. and ring-bearing parts g The legs, 2 and 3,'of the compass'es areprefj, erably made of brass, or similar easy-working metal, and to provide a suitable hard and t durable point on the free end of one of "the legs,`which shall serve the usual and well known purpose, a pointed steel rod, 9, is rig- Ico idly ixed in said leg in the following manner: Said leg, from its lower end upwardly, has a groove, 10, formed therein of suitable length,'and in said Vgroove said rod, 9, is placed, and the borders, x, of said groove are then pressed, or swaged,over, and rigidly upon said rod, thereby permanently fixing it to said leg, as shown in Fig. 1. To provide means for holding a pencil, 71, `'on one leg of the compasses, and means for accurately advancing said pencil in the dij rection of its length, as its point is Worn, or Vthe surface of the pencil. Said dog is pro-l cut away by sharpening it, a split metallic tube, l2, is soldered, or otherwise suitably xed, to said leg, as shown, which slightly expands when the pencil is put into it, and o n said tube, preferably at the lower end thereof, is xed, or bent therefrom, a dog, 13, havingl an edge thereon suitable for engaging with A short split tube, J, is fixed on said leg, 3, a j little above said tube, 12, to aid in holding the pencil which passes th rough it more steady While it is turned to feed it forward and back. The said dog, 13, holds the pencil positively against slipping in the tube, 12, and the angularly arranged dog ou the latter provides for very finely graduating the movement of the pencil. In practice it is found that said screw-feed movement of the pencil through the tube results in marking the latter with spiral convolutions, as shown in Fig. 1. What I claim as my invention is- 1. A uniting joint for compass legs, consistving of a circular plate on one leg having therein a circular groove concentric With a central bolt-hole through said plate, combined with a like` plate on the opposite leg of the compass having thereon an upstanding ring concentric with the central bolt-hole through said plate and fitting closely Within said groove, a handle having two-perforated disks thereon between which said joint-plates are received, and a joint-bolt passing through said joint-plates and disks and holding the parts through which it passes in juxtaposition, substantially as set forth. 2. A uniting joint for compass legs consisting of a circular plate, d, having the central bolthole, e, and the concentric groove, f, therein, combined with the circular plate, d, of the opposite leg having the central bolthole, b, and the upstanding concentric ring, c, thereon for engagement within said groove, a handle, and a bolt holding said joint-parts in juxtaposition, and said handle thereon, substantially as set forth. 3. Means for holding and operating a pencil on a compass-leg consisting of a split tube rigidly fixed thereto to receive a pencil, having a pencil-engaging dog thereon projecting inwardly and standing at an incline relative to the axial line of said tube, substantially as set forth. v 4. Means for holding and operating a pencil on a compass-legconsisting of a split tube rigidly fixed thereto to receive a pencil, having a pencil-engaging dog thereon projecting inwardly and standing at an incline relative to the axial line of said tube, combined with 'a second split pencil-guiding tube fixed on 5. A uniting joint for compass legs consisttion, and said handle thereon, substantially as set forth. MILTON BRADLEY. lVitnesses: I-I. A. CHAPIN, K. I. CLEMoNs.
Description F. B. CANODE. . PENCIL POINTER. v APPLIOATION HLED 11111.19, 1901. i Patented Nov. 14,1911. MO/ww COLUMBIA PLANOGHAPH co.. WASHINGTON D c 'UNITED STATES yrnrniar onirica. FREDERICK B. CANODE, OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO LAKESIDE SPECIALTY COMPANY, 0F CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS. PENCIL-POINTER. Specification of Letters Patent. Patented NOV, 14, 1911 Application led March19, 1901. Serial No. 51,848. To all whom it may concern: Be it known that I, FREDERICK B. CANODE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pencil-Pointers, of which the following is a description, reference being had to the accompanying drawings, forming part of this specification. My invention relatesto that class of machines or devices, commonly known as pencil pointers, in which the ends of lead pencils are pointed by the operation of a rotary cutter driven by hand'or power, and it has for its object the production of a machine of this character which shall be simpler, cheaper and more elficient than those heretofore used. In the accompanying drawings Figure 1 is an elevation of the machine, looking at the side of the machine at which the pencil to be pointed is inserted; Fig. 2 is a side elevation, partly in section, at right angles to the view in Fig. l; Fig. 3 is a sectional detail ofthe rotary pencil holder and its supporting bearing; Fig. 4 a cross-section through said holder and its supporting bearing, such section being taken on line 4, of Fig. 3; and Fig. 5 a detail ofthe rotary cutter. The same letters of reference are used to indicate like or corresponding parts in theV several views. The supporting frame ofthe machine consists of a base A, by which it may be secured to a'table or other support, two vertical end plates C C', and suitably shaped side plates D to form, with the end plates C C, an inclosing casing for the rotary cutter E which is fixed upon a shaft F having its bearings in the end plates C C', and in the present instance (provided with a crank G for turning it by hand. This cutter. Fixed upon the end of the shaft F opposite the handle G is a gearl wheel I-I which meshes with a second gear wheel I mounted above it upon a suitable support projecting from the end plate C of the casing, and in turn meshing with a third gear wheel J llocated above it and carried in a rocking frame K pivoted at L between supporting brackets M M projecting from the end plate C of the casing, Fig. 1, and provided with a thumb-piece K for swinging it on its pivot. This rocking frame K is in the form of a yoke, Fig. l, and has formed integral with gita tubular extension or hub portion N, -Figs 2 and 3,in which fits and turns a sleeve O, having secured upon its right hand or inner end the gear J before referred to.- Fitting within the sleeve O is a second sleeve P whose left hand or outer end is exteriorly .threaded to receive a thumb nut Q. The right hand portion of this sleeve P is split or longitudinally slitted, as indicated in Figs. 3 and 4, (beingpreferably provided with three equidistant longitudinal slits) so as to permit the separated portions of its right hand or inner end to be pressed inward to- 1that when the sleeve is drawn to the left within the outer sleeve Cv which carries the 'gear- J the portions of its split end will be forced inward toward each other and caused Llto grip the pencil. vThe thumb nut Q upon the threaded left hand end of the sleeve P bears against the outer end of the tubular bearing N, so that when said nut is tightcned up the sleeveP will be drawn to the left, with the result just described, and the pencil be thereby tightly held within the sleeves P and O and gear J, so as to turn with the latter. ` A lever S, fulcrumed between ears T projecting from the brackets M, Figs. 1 and 2, is forked at its upper end to engage a'circumferential groove formed on the tubular bearing N. When the lowerV end of this lever is pressed inward, to the right in Fig. 2, the rocking support K of the pencil holder will be swung outward and the axial line of the pencil holder brought to approxisol mately horizontal position. A coiled 'spring U surrounding a rod V projecting outward from the end plate C of the casing bears against the lower end of the lever S and tends to force the latter to position to present the pencil at an angle to the periphery of the cutter, as in Fig. 2. A nutI WV screwed upon the outer end of the rod V serves to limit the movement of the parts in this direction. The end plate C of the casing is cut away opposite the inner end of the pencil holder, as shown, to permit the pencil to project within the casing into Contact with the cutter. Under this construction and arrangement of the parts the use and operation of the machine are as follows: The thumb nut Q on the split sleeve P being unscrewed suiiiciently to permit the split end of the sleeve to spring outward to normal position, the end of the pencil to be pointed is inserted through said vsleeve until its right hand end projects a proper distance beyond the sleeve, such insertion of-the pencil requiring the parts carried by the rocking support K to be swung to approximately horizontal position, by means of the thumb piece K, in order that the unpointed end of the pencil may pass over the top of the cutter E. Upon releasing the parts the action of the spring U will at once throw them toward the position shown in Fig. 2 as far as the cont-act of the unpointedend of the pencil with the top of the cutter E will permit, and yieldingly press the end of the pencil against the end of the cutter. The thumb screw Q is then tightened up, to firmly grip the pencil in the rotary holder. Upon then turning the cutter E by means of the handle G the pencil will be turned,'through the medium of the gears H, I, J, in the same direction as the cutter E, and the adjacent surfaces of the top of the cutter and the under side of the pencil be therefore caused to turn in opposite directions while the pencil is yieldingly pressed against the cutter by the action of the spring U as before described. The `diagonal cutting serrations or knives upon the cutter E will then, as the cutter p and pencil are revolved, cut away and properly taper and point the end of the pencil, whereupon the lower end of the lever S will come into contact with the stop nut W upon the outer end of the rod V and prevent any further downward move- -ment of the pointed end of the pencil, so that after the pencil has been properly pointed further rotation of the cutter will not affect it. By adjusting the stop nut W to different positions, and by projecting the inner end of the pencil to a greater or less extent over the cutter E, the pencils may be pointed with any desired taper within the limits of the machine. After the pencil has been pointed the thumb nut Q will be loosened to release the pencil from the grip of the rotary holder, and teh pencil be withdrawn, and another one inserted and the operation repeated. The shavings from the pencil point fall to the bottom of the casing and are caught in a drawer B which may be removed to empty them from time to time. It will be noted that, owing to the diagonal arrangement of the cutting serrations or knives upon the cutter E, they engage the pencil with a shearing cut, and each serration or knife engages first with the portion of the pencil remote from its eX- treme end or point, so that the material is removed from the pencil with a shearing cut traveling outward toward the point of the pencil, instead of a cut traveling inward from the point toward the body of the pencil as would be the case if the diagonal arrangement of the cutters were reversed. lThe particular arrangement of the cutters shown in the drawings therefore not only causes them to act upon the pencil with a shearing cut, but by causing said cut to travel outward from the body of the pencil toward its point the operation is much more efficient and the liability of breaking the point of the pencil is materially lessened. 'Ihev teeth upon the uppermost gear J bf the three gears are rounded or crowned as shown to accommodate its movement upon the middle gear I in the rocking of the frame K carrying the pencil holder. Having thus fully described my invention, I claim: 1. In a pencil-pointer, the combination of a cutter mounted in a suitable frame or support, a rocking pencil-holder operatively associated with said frame or support, a pivoted lever separate from but engaging the holder, means for forcing the lever in one direction, and means limiting the movement of the lever, substantially as described. 2.
