ATTORNEYS Fatentecl Oct. 27, 1931 UNITED STATES PATENT OFFICE WILLIAM H. ROBBINS AND RAYMOND IE. BGEHLER, JR., OF SPRINGFIELD, OHIO, AS- SIGNORS TO THE WILLIAMS COMPANY, OF LONDON, OHIO, A CORPORATION OF OHIO TAKE-OFF MECHANISM FOR WIRE CUTTING MACHINES Original application filed March 24, 1928, Serial No. 264,413. Divided and. this application filed January through which the wire passes for the purpose of stretching or straightening the wire, and also for the purpose of having the wire cut into determined lengths.

It is also an object of this invention to provide a common means for driving all of the drums and rollers used in connection with this Wire cutting machine.

These and other advantages w1ll appear from the description taken in connection wlth the drawings.

Referring to the drawings:

Figure 1 is a detail side elevation of the take-off and cutting mechanism cutting the wire in sections.

Figure 2 is an end elevation thereof.

Figure 3 is an enlarged section of the cutofl mechanism.

The wire to be operated on 20, passes between the take-oft'

friction rolls

21 and 22, which are geared together by the

gears

23 and 24. These gears are driven by the belt 25, actuated by the motor 26. These gears and take-off drums are mounted in spaced frame members 27, which are connected together by the

shafts

28 and 29. In these frame members the upper shaft 29 is slidably mounted in the blocks 30 and spring pressed downwardly by the springs 31 in order to accommodate for the inequalities of the size of the w re, and to provide slipping or clutch mechanism so that the pull on the wire may not exceed a predetermined amount.

The wire end 20 is passed between a simllar pair of gear-connected take-off drums, the

rollers

32 and 33 geared together by the

gears

34 and 35 and supported in uprights 36. The upper roller 32 has a

similar spring mechanism

30 and 31 as the upper roller of the other pair of take-off rollers. The four rollers are geared together with respect to the intermediate pinion 37 carried on the frame Serial No. 332,911.

member 38. The two spaced frame members 38 are connected by

horizontal frame members

39 and 40. The relation between the rollers or drums and the gears is such that the gears serve as a guide for the wire passing between the rollers. By this means the wire cannot leave the rollers at one end. It is a particular advantage of this structure that appli ants can use a relatively Sl10- drum. or roller and maintain the wire thereon because of the presence of the gears at one end of the rollers or drums, whereby the strands of wire cannot leave the drums except at one end.

The last-mentioned

rolls

32 and 33 are provided with a sliding cutting knife 41, which travels along the edge of a cutting block 42 and projects into a slot 43, such block and slot being contained in a lower roller 33. This provides for chopping off the wire in lengths of given size.

We desire to comprehend within our invention such modifications as may be clearly embraced within our claims and the scope of our invention.

This application is a division of our application, Serial N 0. 264,413, filed March 24, 1928.

Having thus fully described our invention, what we claim is new and desire to secure by Letters Patent, is:

1. In a wire cutting machine, wire takeoff means, superimposed wire engaging takeoff drums, gear means on one side of said drums to gear said drums together and acting in part as guides for said means to drive said gears, yielding means for accommodating the inequalities of the wire and the relative position of said drums, interconnected cut-off drums synchronously driven with the takeoff drums, and cut-oif means associated therewith for cutting off said wire after it has been taken off at intervals.

2. In a wire cutting machine, wire take-off means, superimposed wire engaging take-off drums, gear means on one side of said drums to gear said drums together, means to drive said gears, yielding means for accommodating the inequalities of the wire and the relative position of said drums, interconnected cut-off drums synchronously driven with the 2. mam
