IMPROVEMENT IN CLOTHES-PIN MACHINES.

Specification forming part of Letters Patent No. 147,277, dated February 10,1874; application led i September 8, 1873.

To all whom 'it may concern:

Be it known that we, HARVEY LocKn andl EDWARD W. Locrm, both of the city of Grand ltapids, coimty of Kent and State of Michigan, have invented a new and useful Improvenient in Clothes-Pin Machines, of which the following is a specication, reference being had to the accompanying drawings and the letters of reference marked thereon, and the same are made a part of this specification.

The nature of our invention relates, first, to the arrangement of spindles which hold the stock in a circular rotary frame, 1n combination with a series of circular saws and stationary cutters 5 second, the combination and arrangement of a rotary feed-wheel with the revolving spindles, for the purposes described; third, the device for slotting the clothes-pins, used in combina-tion with the spindles of the turning-lathe of the machine.

In the drawings, Figure l is a front upright view of our invention. Fig. 2 is one of the spindles with pulley rigidly attached. Fig. 3 is a slide, which, in the machine, is attached 'to the spindle, and with the stationary spindle and with the stationary cam gives it its longitudinal motion. Fig. 4 is a side, upright, perspective view of our invention. Fig. 5 is atop view of a portion of our invention, showing arrangement of the circular saws, stationary cutter, clutch, spindles, and feeding dcvice. Fig. 6 is a sectional view of t-he clutchwheel 102 and the stationary cam which operates the jaws of the clutches CIC.

In Fig. 4, Z isa shaft supporting the pulleys B, @,f, g, and 4f. The power may be applied to this shaft in any suitable manner. A band is passed over pulley B and pulley D, which last-named pulley is rigidly attached to the arbor ofthe circular saws S S S, as shown fully in Fig. l. On the shaft Z, just back of the pulley B, is a pulley, 4, (shown in Fig. 1,) which is connected by means of a cross-band to pulley Bf, which is rigidly attached to a shaft, upon which shaft is a friction-pulley, F. Friction-pulley F engages with and operates friction-pulley F', a portion of which pulley is cut away in Fig. 4 to show the arrangement ofthe oval gearing. O is an oval cog-wheel slides revolve.

upon the shaft of friction-pulley F which cogwheel engages with and operates a similar wheel, O. The shaft upon which the oval wheel is placed pierces the oval wheel near its smallest part, so that the cogs on the largest part of one engage with those of the smallest part of the other, and the cogs farthest from the shaft of the one engage with the cogs nearest the shaft of the other, the motion being conveyed from O to O. The arrangement above described causes the shaft of O to revolve rapidly at one part of its revolution, and slowly at the opposite. It also causes alternate rapid and slow motion to all parts of the machine operated from the shaft O. To the shaft of O is attached a small pinion, (shown in Fig. l by t,) which engages with and operates cog-wheel l), and thereby P and T. T is attached to the shaft of the feed-wheels u u, and thereby the alternate slow and fast motion is conveyed to the feed-wheels. The cogwheel T engages with and operates the cogwheel T and shaft to which it is attached, and thereby the rotary motion is given to the circular frame Y Y and wheel t1, and miter-gearing o and the circular frame Q12. The cogwheels T and T are the saine size, and therefore the feed-wheels u u, frame Y Y, and cogwheel e, and frame o1 o2 revolve with the same rapidity, as does also the miter-wheel w1, which engages with and is operated by said Wheel o. The circular frame Y Y supports a number of spindles, each one constructed with the pulley c', as shown in Fig. 2. o1 t2 also support the saine number of similar spindles, as. shown. Fig. 3 is a slide provided with a pin, la, which slides in the groove Hof cam-wheel XV. (Shown in Fig. l.) Itis provided with the projections n n, which iit into the groove m of the spindle-one on either side-in such a manner as to allow the spindle to'revolve freely, and yet to prevent the spindle from having any longitudinal motion separate from the slides. XV is a stationary cam-wheel, about which the R is a similar cam-wheel, and

the grooves H and H are so constructed that the slides holding opposite spindles arecarried forward toward each other at the saine instant, and the feed-wheels are provided with A'rnN'r hrrren notches, as shown, which notches are so arranged that a block is brought into position to be caught between the spindles at the time they are brought toward each other by the cam movement above described. The blocks to be turned into pins rest between the side pieces of the hopper and upon parallel inclines, one of which is shown in Fig. 4 by J, and slide down upon the feed-wheels, and are carried forward, one at a time, by the notches in the feed-wheels, to the spindle, as described above. On each side of the hopper is a metallic or other spring, which presses against the end of the block, and they together hold it in their grasp, so that it cannot fall or become displaced before it is seized. by the spindles. The block is carried downward by the spindles and caused to revolve rapidly, and passes over the saws S S, which cut it into the required form in the rough, when it is carried past the stationary cutter l, (shown in Fig. 5,) which finishes it ready for slotting.

The arrangement of the gearing above de-l scribed is such that cog-wheel O revolves as many times to one revolution of the shaft carrying the spindle-frame as such frame carries spindles, and as many times to one revolution of the feed-wheels as each feed-wheel has notches.

The number of spindles maybe varied in different machines. y

The miter cog-wheel lv engages with and operates the miter-wheel w1. rlhe wheel w1 is provided with a series of clutches, C, equal in number to the sets of spindles. Each clutch is rigidly attached to the wheel wl, and provided with a jaw, as shown in Fig. 6, by 3, hinged to the clutch in such a manner that it is opened and closed by means of the pin 6, which pin 6 slides in the groove of the stationary cam wz. The cam 2v2 is constructed in the same manner as the cams W and R.

By an arrangement of the grooves in camwheels XV and lt, the spindles are withdrawn from the t-urned clothes-pin shortly after it has passed the saws and cutter.

The cam-wheel to2 is provided with a groove running entirely around it, a part of the way being nearer the inner side ot' the wheel, and a part of the way nearer the outer side of the wheel. The pin of the jaw, while passing in the groove toward the inner side ofthe wheel,

closes the clutch, and while passing in thev groove toward the outer side ofthe wheel the clutch is open. rlhe arrangement of the canigroove is such that the pin of the jaw passes from the outer to the inner side of the camwheel at the point where the spindles are withdrawn from the clothes-pin, closing the clutch, which is then in position to clasp the clothes-pin, and the pin in the clasp of the clutch is carried by the revolution of wheel w1 until it is passed by the slotter Sf, when the pin of the jaw C again passes toward the outer side of the wheel wl, opening. theclutch and releasing the finished pin.

The slotter is provided with two or more knives or cutters, which trim the outer end of the slot into the desired form. The arrangement of wheel w1 is such that the slow motion is given to it as the pin is brought in contact with the slottin g-saw, and the arrangement of the revolving frames that support the spindles is such that they have the slow motion as the stock is carried over the saws S S S and cutter l. The arbor of the saws S S S is sup ported by the frame 7 7, which is hinged to the part 9 by means of a rod passing through the part 9, and hung as shown in Fig. 4.. This allows the saws to be adjusted to stock of any size by means of the set-screws a and a. a passes through the part or support E, and against the frame of saw-arbor S S S; and a. passes through the frame of the arbor against the frame of the machine. L is a lever turning on a pivot, l', operating the lever L which is attached to the shaft of friction-pulley F, so that pulley F may be withdrawn or applied to friction-pulley F at pleasure, the disconnecting of pulleys F and Fl causing all the machinery operated from pulley F to cease to work.

This machine may be used for turning many other articles besides clothes-pins.

Having thus described our invention, what we claim to` have invented, and desire to secure by Letters Patent, is n i l. The revolving spindles, constructed and operated as described, in combination with the saws S S S and the stationary cutter l, constructed and located, relatively to the spindles and the saws, in the manner set forth.

2. The revolving spindles supported by the circular rotary frames, in combination with the feed-wheels u u and springs, arranged as described.

3. The revolving and rotating spindles having the grooves on, and provided with the slides, Fig. 3, constructed as described, and supported on the rotary frame'and operated positively by the stationary cam W, as speciiied.

4. rEhe wheel w1, provided with a series of clutches operated by cam 102, in combination with the revolving spindles carrying the pinblanks for the purpose, by an automatic operation, of taking each turned pin-blank from the spindles and presenting it to the operation of the slotting-saw S.

5. The combination of set-screws a and a. with the hinged frame 7, for the purpose of adjusting' the saws S S S, for the purpose described.
