JAMES S. JOHNSTON, OF UTIOA, NEW YORK, ASSIGNOR OF OI E-IIALF TO KATHERINE MAGNER, OF SAME PLACE.

NECK h/lARKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 678,784, dated July 16, 1901-. Application filed May 12, 1900. Serial No. 16,436. (No model.)

the accompanying drawings, and to the characters of reference marked thereon, which form part of this specification.

My invention relates to improvements in neck-marking machines-that is to say, a machine for creasing or impressing the fabric of wrapper material to form a guide for cutting and sewing.

In the drawings, Figure 1 shows a front elevation of my machine with the machinetable broken off to shorten the figure. Fig.

.2 shows an end view of the same as shown in Fig. 1. Fig. 3 is a plan View. Fig. 4 is a partial vertical section showing details of construction. Fig. 5 shows details of construction of the mechanism for supporting and adjusting the table of the machine. Fig. 6 shows a cam employed in the machine.

The machine consists of a small rectangular frame 1, adapted to'be secured on a table A. lVithin the casing and supported in bearings in the end wallsis a shaft 2. The shaft 2 carries the band-wheel 3, running loosely thereon, and the cam-body4, the cam portion of which is indicated by 5. On top of the frame 1 are provided projection-supports 6, provided with the open bearings 7 at their upper end. The bearings 7 receive the short shaft or pivot 8, secured in the end of the arm 9 of the die or marker 10. The arm 9 of the die is provided with an opening 11, spanned bya crossrpin 12. The connectingrod 13 connects the pin 12 with the eccentric 5that is to say, the connecting-rod 13 is provided at its lower end with the usual clamp 13, surrounding the eccentric 5, and at its upper end is provided with a U -shaped notch 13", opening in a horizontal direction to receive the pin 12. For securing the connecting-rod in connection with the pin 12 there is provided a removable holding-pin 14, the

arrangement being such that when the pin 14 is removed the upper end of the connecting-rod 13 can be freely disconnected from the pin 12. The end of the die-arm 9 is eX- tended in a short hooking projection 9", which receives the hooked end of the sliding link 15. The lower end of the link 15 is provided with a perforated offset 15*, through which passes the rod 16, secured in the base of the frame. threaded, as shown, and provided with a nut 17, and 18 is a spring interposed between the nut 17 and the offset 15 with tension to cause hook 15 to draw down on the hook projection 9 to elevate the die 10 and maintain the pivot 8 in the bearings 7. The die 10 is adapted to operate on the goods placed on an adjustable spring-supported table 19. The table 19 may be extended to any suitable length to accommodate any width of goods desired and is preferably provided at the point where the die operates with a rubber or elastic cushion or pad 20. At either side of the cushion 20 and at either side of the point at which the die operates there is provided a series of markers a ct, arranged at equal distances. The table 19 is received directly on the faceplate 21, secured upon the upper end of the plunger 22. The plunger 22 is preferably square and extends into a square barrel 23. Between the lower end of the plunger 22 and the lower end or bottom of the barrel there is interposed a stiff spiral spring 25. In the lower end of the plunger 22 is provided a screw threaded opening 22, adapted to receive the screw-threaded upper end of the stem 24. The lower end of the stem 24 passes through an opening in the lower end of the barrel 23 and is screwthreaded on its lower portion, as indicated at 24, to receive the stop-nut 26. On the extreme lower end of the stem 24 is provided a hand-wheel 27, by means of which the stem may be rotated in operating the screw. By screwing the stem 24 more or less into the opening in the lower end of the plunger 22 and by adjusting the stop-nut 26 the table can be adjusted into a position to properly cooperate with the die.

For communicating motion to the shaft 2 and the cam-body 4 and stopping the same at The upper end of the rod 16 is screwthe end of every revolution the following mechanism is provided: The band-pulley 3, which runs loose on the shaft 2, is provided with a clutch-tooth 28. When the pulley 3 is shifted laterally to permit it to do so, the clutch-tooth 28 is adapted to engage with the clutch-tooth 29 on the end of the body 4:. The hub of the pulley 3 is provided with a groove 30, which receives the rib 31 of the shiftingfork 32. The shifting-fork 32 is provided with a stem 33, which engages in a boss and opening in the frame 1. Coiled about the stem 33 is a spring 34, attached at one end to said boss and at the other to the shifter 32 and tends to move the shifter and pulley toward the left as the device is shown in Figs. 1 and 4. The shifter 32 carries the campin 35, the projecting end of which is adapted to engage with the throwing-out cam 36 on the cam-body l. The pin 35 is forced toward the cam-body 4 and the shaft 2 by a spring 36, interposed between a collar 37, secured on the pin, and a plate or disk 38, supported by posts or hangers 39 from the shifter 32. The lower end of the pin 35 is connected with a treadle on the fioor by a connection which may be attached at the eye 40. In order to give firmness to the construction, the shifter 32 may be supported by a bracket-arm 41, having a slotted opening through which the lower end of the pin 35 passes, the slide permitting the pin to play freely with the movement of the shifter. I I

As before suggested, the machine is placed on a suitable table and secured, and the lower end of the pin 35 is connected to a treadle on the floor in suitable position for the operators foot. The belt (indicated by B) preferably passes upward through the table and passes around the pulley 3, as indicated in Fig. 3. The machine having been adjusted properly and the pulley 3 being in motion from the belt and running loosely on the shaft 2, the operator takes the goods to be operated on (usually a piece of tubular fabric for a wrapper-shirt) and places it on the table, lo-' eating it by the markers at so that the impress will be received at the right point. The footis then pressed upon the treadle, withdrawing the pin 35 so as to disengage the cam-face 36 The shifter 32, with the pulley 3, is then immediately shifted into operative position by the action, of the spring 34. The clutchtooth 28 then engages with the clutch-tooth 29 and the cam is put in motion. The action of the cam is to draw on the connecting-rod 1.3 and move the die 10 down onto the goods on the table with considerable pressure. Vhen the cam has made nearly a complete revolution, the throwing-out cam 36 comes into operation, engaging with the projecting end of the pin 35, which in the meantime has assumed its normal projecting position, and the continued operation or revolution of the cam-body by the action of cam 36 causes the shifter, 32, with the pulley 3, to be moved toward the right as the machine is shown in Figs. 1 and 4 until the clutch-teeth are disengaged and the shaft released. At the end of the throwing-out cam 36 there is preferably provided a stop -rib 36, which may strike against the pin 35 in case the cam has not come to a complete stop before it has done so and limits the revolution at this point. In its descent upon the goods the die leaves the impress of its edge 10 on the goods in the nature of a crease or indentation. The spring supporting the table permits the table to yield under an excessive thickness of goods or material being operated on, and also al lows it to yield, if necessary, until the die has descended to its lowest position, whereby the impression of the edge 10 is applied throughout its entire length.

It may be noted here that I prefer to form the edge 10 with a series of'elongated teeth, as indicated at 10", although a straight edge not separated into teeth answers very well. In the descent of the die 10 upon the goods the amount of pressure which is effected will be determined by the strength of the spring 25 supporting the table of the machine.

To provide for the several different sizes which it is ordinarily necessary for these machines to be adapted to operate on, I provide a set in sizes of dies 10 for the machine, including the arm 9 and the pivot 8. One die or marker can be removed from the machine and another substituted very readily by'removing the pin 14 and detaching'the head from the pin 12 and throwing the die and arm over, so as to disengage the pivot 8 from its bearings and disengage it from the link 15. Another die can be inserted and placed in the machine, as is obvious.

What I claimas new, and desire tosecure by Letters Patent, is-

1. In a marking-machine of the character described, the combination of the die mounted on the end of a pivoted arm, a cam and connecting-rod for operating the die, an automatic stop-motion for the arm and a springsupported work-table having a pad, substantially as set forth.

2. In a marking-machine of the character described, the combination of the removable die, the pivoted arm on which the die is mounted, the cam, the connecting-rod engaging the arm between its pivot and the die, and the spring-supported work-table, substantially as set forth.

In witness whereof I have affixed my signature, in presence of two witnesses, this 10th day of May, 1900.

JAMES S. JOHNSTON.
