IMPROVEMENT INMACHINERY FOR MAKING CLOTHES-PINlS.

Specification forming part of Letters Patent No. 14.4,152, dated October 28, 1873; application iiled September 12, 1873.

To all whom it may concern:

Be it known that 1, J oHN B. SMITH, of Sunapee, in the county` of Sullivan and State of New Hampshire, have invented certain new and useful Improvements in Machines for Making Clothes-Pins; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings,- whicli form pa-rt of this specication. Y

My invention relates to improvements in machines for turning clothes-pins.

In the drawings, Figure l is a planview; Fig. 2, a front elevation, Fig. 3, a vertical transverse section on the line y y, Fig. 1; Fig. 4, a detached view of the head-block of the cutterbed; Fig. 5, a transverse section of the knife and its bed; Fig. 6, a detached view of the cutting-knife. i

My invention consists of the various devices and combinations of parts, as hereinafter specified and claimed, wherein- A represents th'e frame of the machine, on which the different parts of the machine are supported. Motion is communicated to the different parts of the machine through the medium of the bands and band-wheels B1 B2 B3 on the crank-shaft B. The band-wheels B1 B2 communicate motion tothe spindles O O1 and the band-wheel B3, the band b of which asses over a pulley on the shaft b', on the eri' of which shaft is a small gear-wheel, c, engaging: with the larger gear-wheel c on the shaft D. On this shaft D arethe different cams E F G,

y through which the different motions to the several parts of the machine are communicated. O C] are the spindles, working in bearings C2 O2, the one O being the dead-spindle, and the one Ol being the .oscillating or movable spindle. His the knife-bed, made weighty, and hinged at its rear to the base portion l-l'l. In this bed the knife h, Fig. 6, is placed, and secured by set-screw h', Fig. 5. Attached to the face of the head-block I,fwhich extends over and in front of the knife h, is a chamfcr-,cutter, t, and a rider-gage,7 i. H2 is a liftingrod, attached to the pivoted cam-rod f1, which cam-rod is actuated or eausedto rise and fall by the cam F.` The other end of this rod 1 passes up through the base H1, and impnges against the bottom of the knife-bed H. Attached to and in ont of the base H of the knife-bed are two stops or spurs, .l J', one of said stops being station ary and the other movable. The stop J has a rearwardly-projectin g arm, j, by which it is pivoted to thebase H.

Attached to the front lower part of this stop cam G and connecting-rods g and pivoted cam- 4 arm g. Extending from the top front portion of the frame of'jthe machine is a frame,'L, on which a table, L', oscillates. (See Fig. 3.) llhis table receives its oscillating movement from the pivoted arm"6, connecting-rod 7, pivoted cam-arm 8,.and caml 9. On the front end of the frame Il is pivoted a weighted pawl, ll, which engages with the ratchet-wheel M on the oscillating table L. Vithin this table Ii', and extending from end to end of saine, is a feed-belt, l', Fig. 1, which feed-belt is operated or moved a little forward at every forward ymovement of the table by the pawl and ratchet l M. Attached to and projecting a little beyond the inner end of the table L are spurs m ml.

The operation of the machine is as follows The blocks, sawed into the proper size, intended to be turned into clothes-pins are placed on the feed-belt l', and fed up to the spindles C G1 by the revolving of said belt and the oscillation of the table L, in which said belt is hung. The v blocks are thus pressed against the upright spurs or stops J J, one of said stops being stationary and the other movable, while being held in position on the projecting spurs m m on the end of the feed-table; the object and use of said stops and spurs being to hold the block in proper position for centering. The block, being now in position, is caught and slightly pressed up against the dead-spindle O by the cam a: on wheel K, and held by the fine points of the spindles until the feed-table retires. Another cam, y, immediately presses the centers home rmly, justA before the knife f! Y @MASQ h touches the block. The block being' now rcvolving, the knife is let down by means of thc lowering-and-lifting rod HZ, operated by a cam, F, and thus the clothes-pin is turned by a single movement of the knife. A rider-gage, i', is placed on the knife-bed, over and in front of the block, for the purposes of gaging the shaving, and preventing the block flying out from between the centers. A chamfer-eutter, i, is also placed on the knife-bed, for the purpose ot' rounding the end of the pin intended to be slit. The knife is now lifted from the pin by the lifting-rod H2 and the oscillating spindle.

C1, and the rod j', with the oscillating spur J, is withdrawn by the spiral spring 4, the stop or spur J pushing against the end ofthe clothes pin, and partially shoving it off the stationary center C'. The pin being now released, is knocked from between the centers by the hammer 5, operated by the cam G, and drops into a receptacle below, and may be conveyed by spout or otherwise away from the machine.

Having thus described my invention, what -I claim as new, and desire to secure Letters l. The combination of the shaping-knife 71, swinging knife-bed H, the adjustable liftingand-lowering rod H2, lever l, and cam F, with a suitable frame, A, substantially as and for the purposes described.

2. The combination. of the automaticallyswinging knife-bed H, chainfer-cutter z, and rider-gage i', substantially as and for the purposes described.

3. The automatic uncenterin g-hammer 5 and its operating connections Gr g g', substantially as' shown, and for the purpose described.

4. In a clothes-pin machine, the automatic- `ally-oscillating feed-table L', in combination with the spindles C G1, as and for the purposes set forth.

5. The endless feedbelt Z', in combination with the oscillating table L', vratchet-wheel M, counterbalanced pawl l, and frame L, all con structed, arranged, and operating substantially as and for the purposes described.

6. The shaping-knife h, oscillating, spindlel l'itnesses: v
