MACHINE FOR MAKING WIRE CLOTHES-PINS.

SPECIFICATION forming part of Letters Patent No. 276,575, dated May 1, 1883.

Application mea November 3, 1cm. (No model.)

To all whom it may concern:

4Be it known that I,ALLAN E. FRANCIS, of Cleveland, in the county of Cuyahoga and State of Ohio, have inventedV a new and useful Machine for Making Wire Clothes-Pins, of which the following is a specification.

The nature and objects of this invention will fully appear from the subjoined description, when considered in connection with the accompanying drawings.

IV shows same after third bend. V shows same after it has nearly passed through the ceiling operation. VI shows the completed pin. These operations are performed by the parts of the machine illustrated in the several gures., in connection with the several forms shown,in rapid succession, as follows:

A in the several figures is a shaft, on which are placed a series of cams which operate the several devices for producing the several successive results before stated. plete revolution of said shaft one complete pin is made. bearings under the table of the machine, which table also supports all the working parts. Shaft A is operated by a gear-wheel, A2, attached to one end and located outside of the table-supports, being connected with a pinion, A3, on a parallel shaft, A4, located lower down iu the said table supports, and having the driving-pulley from which the machine derives all of its movements. A permanent shaft, A5, is arranged at one side of the machine, the use of which will hereinafter appear.

The first movement of the machine is the feeding and straightening of the wire from a reel. The feeding device consists of a pair of feed-wheels, b b, set in a bracket, B, depending from the right-hand end of the table-top. These wheels are operated by a bevel-gear, b2, on an'extension of shaft A., and have a con- The said shaft A is set iu suitable IOC stant but slow and steady movement, taking the wire from a reel. (Not shown.) The wire, after passing through said feed-wheels, is passed through a guide-arm, b3, extending outward from the table 5 thence between straightening-wheels c c c, arranged near the righthandrend and front corner of .the table. The upper of said wheels c is set in a post, C, with an adjustable bearing, for the purpose of regulating the tension ot' said wheels upon the wire and presenting a straight wire for the first operation in forming the clothes-pin. Froln the straightening-wheels the wire is fed by an intermittent movement produced `by means of a device as follows: To the under side of the table is pivoted a lever, D, having a segment-gear, d, meshing with and operating a companion segment-gear on a turning post, d2, extending upward through the table and carrying a curved arm, di. The said lever D is operated by the cam l on the shaft A. This cam l consists of two Wheels having their inside opposing rims constructed with inclines for moving the saidlever D at the proper times, the end of the lever operated by said cam having a friction-roll, d4, playing in the space between the rims of said double wheel l. On the topof the table are fixed ways E, in which a sliding cross-head, c, plays and is operated by means of a link, e2, connecting it with the moving end of the curved arm d3. AThe under side of said cross-head is provided with grippers e3, which grip the wire and carry it forward in the forward movements, but release the wire in the backward movements. The wire is thus fed forward successively at suitable intervals from the slack wire between the feed-wheels and the straightening-wheels. A pair of grippers, e4, are located at the side of blockf, which catch and hold the main wire when the feedin'g-grippers e3 are moving back. This is to prevent the wire being withdrawn from the block f.

At F is located a cutting device consisting of a short lever pivoted in a slot in the table, and having a cutting-edge playing against the face of a small block,f, attached to the table, near the end of the ways E, and through which the wire passes.

or lug,f2, on the cam 2, whereby the blank for each pin is cut off at suitable intervals. An adjustable stop,f3, on the table'serves to prevent the blank from iiying or jumping when cut od. At this stage the blank is carried by the first bending device, which forms the first bend, Las seen at 1I in connection with Fig. 4, in the following manner:

G are ways located crosswise of and above theltable,in which a sliding block, g, plays, and which carries a pivotal arm, g2, that carries the blank wire with it when it moves across the table. This movement makes the first bend by carrying the wire between two blocks, g3, secured to the top of the table. This operation is performed by the following means: To the side shaft, A5, is attached a vibrating Thelower endof Asaid lever F is struck by a projecting pinv lever, H, operated by a pitman, h, attached by a pivotal joint, said pitman being bifurcated in its forward end, and 'straddles the shaft A, as seen in Fig. 3. Upon the shaft A is a cam, 3, in the side of which is a groove of the shape of the cam, in which a piu, h2, on the side ofthe pitman h plays. To the top end of the tilting lever His attached a connecting-rod, 7b3, connecting said lever H with the sliding block g, by means of which the said sliding block is operated. The arm g2 has a notch in its lower end, covered by a latch, fi, consisting of a small rod playing in lugs on the side of the said arm, and provided with a spring, i2, which keeps the latch down. The wire, as it is carried forward b v Athe feeding device before described, is passed through the said notch in arm g2, and is held therein by the latch; then the blank, having been cut off, as before stated, is carried across the table, and at the same time, receiving its first bend,is now located in the slot opening insaid table, and lies over the diesjjZ, attached to the under side of the table and at each end of said slot. The said blankwireisnowready. for the next operation. This consists in forming the bend and curling the end of said blank, as seen at Ill in connection with Fig. 5, by the following means: 0n the top of the table are secured two blocks,7c 7c, in which a spindle, k2, is placed,having a formingdie,7a3,attached on the endnext to the aforesaid slot-opening in the table, and arranged to operate, in conjunction with diej, for forming the bend in the Ill stage of the operations. On said spindle, between the blocks k 7c, is fixed a short crank-arm, l, and on the spindle outside the block is placed a spring, 7a4, for the purpose ot' drawingthe spindIeback,ashereinaftershown. To the crank-arm l is pivoted a link, Z2, which is held in a perpendicular position by a second wire link, 13, connecting it to the side of the table. This allows thelink l2 tohave an up-and-down movementfor operating the spindle and its die, which movement is performed by the cam 4 on shaft A. It is provided with a side leaf, m, which serves to push the spindle anddie forward over the die j by the said leaf engaging with the link'ZZ. Then the cam engages with the link, and, raising it, brings the forming-die 7c3 down onto the wire and forces it into the said die j, thereby forming IOO the bend and crook, as shown in form III. Y

The coil in the end of the wire is performed by the same cam, operating a spindle, a, fixed on the under side of the table in bearings n2. It has a segment-gear, o3, by means ot which it is given a half-revolution by ashortsegmental rack, n, attached to the cam 4. Said spindle whichimmediately flies back by the force of of the spring oa placed onto it for that pur-v pose. The opposite end of spindle a hasa small wheel, on which is wound a cord, or",

rotates the spindle back again, ready for repeat-ed operation. During this operation of turning the end of the wire the forming-die still holdsthe wire down until thisend of the wire is finished.

The next operation is to form the bend and crooks in the opposite end of the wirethe next stage of the operation. Thisis performed by another cam, 5, of similar construction to cam 4, operating a second spindle and forming-die lo p2, of like construction to the one already described, the former one working in advance of the latter. In the meantime, also, the carrier-block g, with its pivotal arm g2, is carried back acrossjthe table, ready to receive the next blank wire. At this stage another operation takes place-that of coiling the central portion ot' the wire, as seen in form V, the device for which consists of a spindle, q, set in a sliding block, q2, playing in the ways r r, set abovc and across the table, in like manner to that of G. The said sliding block g2 is operated by means ofa connecting-rod, s, connecting it with a tilting lever, s2, having an anglearmts3, operated by a cam, 2, on shaft A. The spindle q has on its central part a pinion, t, meshing with a broad rack,'t2, secured to the top ofthe table, the object ot' which is to revolve the spindle as it is carried over it.

This spindle also has a lateral movement for the purpose of carrying the coiling end over to the wire to be coiled at this stage of thework. VTo accomplish this lateral movement the end of the spindle q has a head on the'end, which plays in a groove inthe end of a slidingplate, u, arranged on "the top of the table, which plate has a depending arm, u2, through a slot in said table, and basa friction-roll, and is operated by a cam-wheel, 6, on shaft A. Previous to this operation, and just as the tirst forming-die releases the wire, a wire-holding device, V, holds the wire for the coiler to take it. This holder consists of an arm, v, attached to a sliding plate, o2,.located on the underside of the table, and which is operated by camwheel 7, in like manner to that of plate a. The camwheels 6 `and 7 have their rims so constructed as to move the said plates at the proper times and length of time to perform their` functions. Thus when the coil in the wire has been completed the said holder and coiler are withdrawn and the coiler is carried hack across the table, ready for a repetition of its work. After the said coiler has completed the coil, and before the forming-die releases the pin, a plate, fw, arranged on the top of `the table, is operated in a similar manner to plate a by a side projection on cam-wheel S, i which gives a quick short movement to said plate fw, which has a projecting point, 102, on forward end, that strikes against the end of the wire and forms the last bend. (Seen at in form VI.) This completes the pin,and then the said `formingdie is released by `its cam,l

which then iies back,and the pin, being freed, falls into a trough, T, and slides down and drops into a receptacle beneath.
