HORACE R. FENNER, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO REG- NELL, BIGNEY & CO., OF ATTLEBORO, MASSACHUSETTS, A FIRM.

WIRE CHASING OR MARKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 71 5,774, dated December 16, 1902.

Application filed anuary 18, 1902. Serial No. 90,297. (No model.)

To all whom it may concern.-

Be it known that I, HORACE R. FENNER, a resident of Providence,in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Wire Chasing or Marking Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in machines for chasing or marking wire or like material at intervals, more especially for wire making the links of chains, in which it is desirable to so locate the marks as to have one appear at a certain place on each link.

It is fully described and illustrated in this specification and the annexed drawings.

Figure 1 shows a vertical section of the machine, taken on the line 1 1, Fig. 2, with the shaft and pulleys in elevation. Fig. 2 represents a vertical section taken on line 2 2 in Fig. 1. Fig. 3 is a perspective view of-the sliding wedge inits ways.

The construction and operation of the machine are as follows:

A represents the bed-plate of the machine, which may be placed on a table or bench or be supported on leg-frames of its own.

D D are standards secured to the bed-plate A by means of screw-bolts c c. A main shaft 0 is held in bearings in the upper'ends of the standards D, on which the main roll B, driving-pulley J, and balance-wheel F are made fast. A sliding die block N is held in the standards D, having a friction-roll (1 held in a tubular recess in its top and the marking or chasing die It inserted in its under side.

A lower die-block E is held in the lower end of the standard D and has a friction-r0110 inserted in its under side, that rests on a sliding wedge K, which raises the die-block E up and lets it down at the proper time.

The main roll B has a series of rolls a a let into recesses in the periphery lengthwise of the roll, so as to be held in the recesses, but allowed to project a little beyond the surface, so that when the main roll B revolves the lesser rolls a a will strike the friction-roll d in the top of the die-block N and force it down to be raised again by the springs e e, placed between the two dieblocks N and E when the cam has passed. (See Fig. 2.)

The raising and letting down of the lower die E at the proper time is done by means of the wedge K. (Shown separately in part in Fig. 3 with the ways in which it slides.) The sliding of the wedge K is accomplished by the cam S on the shaft H and by the cam S on the shaft L, which bear against the friction-rolls f f, held in the faces of the blocks P P, secured on the wedge K. (See Fig. '2.) The shafts H and L are connected by gears G 6 and M, so that the former shaft will turn twice as fast as the latter and the cam S will give two motions forward to the wedge K to one of the cam S. This arrangement is for the purpose of making one or two impres- 7o sions on a given length of. wireas, for instance, on one side of a link or on both sides of itand onlyone cam is used at a time, the rollf being removed from the block P or P when the other cam is in use.

Adjustable jaws 76, having a set-screw y, are shown in Fig. 1 to hold the wire W taut and a set-screwt to adjust the dies to the arbor 'r'.

The operation of the machine is this: The 80 wire W is passed through between the upper and lower dies h and e, (see Fig. 1,) and in case of a chain-machine is wound around an arbor 1", held in a shaft R, which is driven with an intermittent motion by means of gear R. Motion is given to the main shaft 0, and the cam in use--say cam Swill push the wedge K underneath the lower die E and raise it and the wire W, so that the rolls a a in the main roll B will come in contact with the roll 01 in the upper die N and push it down and mark the Wire with the die It, and when the cam. S has passed the roll f the wedge K will be drawn back by the spring 9. (See Fig. Then the lower die will drop, leaving the wire W free, and the shaft R will make one turn and wind a link on the arbor 0'. By this time the cam S will make a turn and begin to push the wedge K in again to make another mark on the Wire W, and this succession of motions are continued so long as the main shaft runs.

Having thus described my invention,what

I claim, and desire to secure by Letters Patent, is

- 1. In a swaging-machine, the combination of a pair of die-blocks, arranged to move in a vertical path; means for forcing the upper block downwardly; a wedge member arranged to reciprocate and thereby move the lower block toward the upper block, and permit it to move away from the same; a cam arranged to engage the wedge member and move it to raise the lower block; and a retractile spring arranged to move the wedge member in the opposite direction.

2. In a swaging-machine, the combination of a pair of die-blocks arranged to move in a vertical path; means for forcing the upper block downwardly; a wedge member arranged to reciprocate and thereby raise the lower die-block; a removable friction-roller on the wedge member; a shaft having a cam thereon arranged to engage said roller and thereby move the wedge member to raise the lower die-block; a retractile spring arranged to move the wedge member in the other direction; a second friction-roller removably mounted in the wedge member; a second shaft driven from said shaft; a cam on the second shaft arranged to engage the second roller and thereby cause the wedge member to raise the lower die-block; the cams being arranged to move the wedge member at different relative periods; the engaging cams and rollers being so arranged that when either roller is removed from the wedge member, the latter will be moved by the other roller and its engaging cam, without being affected by the rotation of the other cam.

In testimony whereof I have hereunto set my hand this 20th day of December, A. D. 1901.

HORACE R. FENNER.

In presence of- HOWARD E. BARLow, BENJ. ARNOLD.
