MACHINE FOR STAMPING MARKS ON WIRE OR THE LIKE Filed July 5, 1929 ZSnventor FRANK E.STAHL f attorneys Patented Apr. 14, 1931 UNETED STATE-S FFECE FRANK E. START, OF TONAWANDA, NEW YORK, ASSIGNOR TO THE COLUMBUS- MCKINNON CHAIN CORPORATION, OF TONAWANDA, NE'W YORK, A CORPORATION OF N EW YORK MACHINE FOR STAMPING MARKS ON W'IRE OR THE LIKE Application filed. July 5, 1929. Serial No. 376,095.

This invention relates to machines for impressing identifying characterstrade-marks for exampleon rods, wire or other strands of metal and is more especially designed for 3 so marking such articles as are intended to be cut up into pieces for forming chain links.

The object of the invention is to provide improved and simplified means whereby the work referred to may be neatly, rapidly and i9 economically done.

The invention is-embodied in the example herein shown and described, the features of novelty being finally claimed.

In the accompanying drawings Figure 1 is a view of themachine in side elevation.

Fig. 2 is a top plan view partly broken out.

Fig. 3 is a side and sectional view on a larger scale of the character-impressing means.

20 Fig. 4 is a top plan view of the same.

Fig. 5 is an elevation looking at the right hand end of Fig. 4.

In the views designates the frame upon which is fulcrumed at 11 a die pressing lever "having a long arm 12 and ashort arm 12. Said long arm 12 is provided with a small roller 13 journaled near the end thereof actuated by a cam 14 journaled at 15 in the frame. Said cam has a high portion adapted, when 30 the cam is regularly rotated to depress the shorter arm of the lever at regular intervals.

The character-impressing means includes an anvil or stationary block 16 having in its upper face a longitudinal groove for the movement of the wire, said block provided with a pin 17 for setting it inthe table of the frame, and a movable block 18 pivoted by the stud bearings '19 in plates 20 secured to the opposite sides of the correspondmg end of the base block so that the upper or movable block can swing vertically on said bearings 19.

The upper block 18 has a longitudinal groove in its lower face to match the correspondinggroove of the lower block, and at its lower side the upper block also has a rect'angular recess in which is fixed the markcontaining die block 22. The die block 22 is placed in said recess between two other plain filler blocks 23 and 24: also in said recess and all three are pinched tightly together by a set screw 25 in the free end of the holding block 18. By releasing the screw 25 the die block can be replaced with a fresh one: and by suitably varying the sizes of the blocks 2?) and 2a the die or trade-marking block 22 can be differently located in the recess or a larger or smaller marking block used.

Coiled springs 26, 26, having their respective ends seated in sockets in the top and bottom blocks 16 and 18 are provided tending normally to" hold said blocks separated as shown in Fig. 3 with the marking block off the wire or rod to be marked.

The shorter arm 12 of the die pressing lever is provided with a screw 27 threaded thereonto and having a plain end to bear on top of the die holding block 18 to depress the same to make imprint of the trade-mark in the wire or rod, a piece of which is shown at 28. Said screw can be adjusted and fixed in ad usted position by a jam nut 29 to vary the depth of the imprint to be made.

In practice mechanism operated by power can be provided to move the wire with an intermittent movement through the grooves in the blocks 16 and 18 and while the roller 13 of the longer arm 12 of the die pressin -lever is at the low part of the cam; and during the intervals of the wire feed and while the wire is at rest the marking die will be depressed by the operating high part of the cam. I

The forms of the parts can be changed without departing from the gist of the invention as claimed.

lVhat I claim is:

1. Means for impressing marks on a wire or the like including a pair of elongated blocks, one of which is stationary and provided with a longitudinal wire-guiding groove in its upper face, and theother of which blocks is pivoted at one end to said stationary block to swing in relation thereto, said pivoted block having a marking-die-receiving cavity and a groove at the pivoted end opposed to and cooperating with the groove of the stationary block to form an entrance and guide for the wire between the pivoted ends of the blocks. a marking die carried by the pivoted block, and means for interinittingly pressing said piveted block and m arking die toward the stationary block.

2. Means for impresslng marks on a Wire 01' the like including a pair of elongated'blocks,
