WIRE-DRAWING SAFET DEVICE.

To all whom/it may concern?,

` lBe it known that I, MICHAEL SriANLNON, a citizen iofthe'United States,`and a resident ofllluncie, county of Delaware and `State of Indiana, have invented a certain new and useful VWire-Drawing Safety Device 5. and do hereby declare that the following is a full,` clear, and exact'description thereof,`

reference being had to the accompanying drawings, in which like letters refer to likeV parts. Y

The object of this invention is automatically to stop a wire drawing mechanism when thewirelbecomes entangled soV as tov prevent the breakage of the Wire and also to pre\f'ent accidentsto wor-Innen who might become entangled 1n the wire and miht unless' the device'were stopped, lose fingers, arms, or legs. Thisobject 1s accomplishedV by a particular arrangement whereby when the wire becomes entangledthe reelfrom which it is being u nwound, will be' bodily moved, and'upon such movementwill actu-Y ate particular means for causing the instant stoppage of the actuating mechanism.

The chief feature of the invention consists in mounting the reel onv a spindle or support which* is mounted in ak platform o r'nbase frame. To that end upon the frame a guideway is provided yextending toward the wire drawing part of the mechanism, and -the base of the spindle or reel supportrests flatly upon such Abase 'frame withinV the guideway and loosely, lwhereby it willfbe held in place, under normal actiom by the weight of the reel and* wire, and yet will; yield or slide toward thewire drawing part of the machine when the wire'I becomes caught or entangled.` Also the spindleor support for the reel, merely vresting loosely upon the base frame, enables the reelto be readily tilted over when acoil of vwire yon the line 3 3 of Fig. 1. Fig. 4 is al secspecifieatioa'ofvrettersraterit.

Said spindle40 5has a base ,41, as seen inAV Fig. Y. 3, which is slidable in a 'guideway` formed by angle guide bars 42 parallel with each other and.eXtendingtowardl-the wire itsk right handend looped so as to fit looselyl over the reduced upper endl ofthe spindle and therefore may be readily elevated vout ofthe way, as shown in Fig. 1, when it is deslired to remove the reel or put on a new ree f 95, ward froml the base. The up'perfend Vofthe drawing frame. vThe connecting rod 39 has Y While .the device is operating, the parts are in the positions shown in Fig. 1. When, however, ythe wire becomes entangled so as not to be readily unwound from the reel 16,

it will draw the reel 16 toward the wire drawing device, as shown in F ig.r2. That` actuating mechanism and'L the machine stopped, untilthe wire can be untangled and the parts replaced in their normal positions. The weight of the reel 16 and wire on it creates sufficient `friction between its base 4:1

Y and the platform or base of the machine 12 to hold the reel normally in proper position and to supply suflicient resistance to the pull of the wire 15 as it is being drawn, likewise a sulliicient resistance between the reel. 16 and the spindle 40 for holding the wire 15 taut. The connection of the rod 39 with` the spindle l0 is such that any ordinary wire reel can be used,`and the reel can be tipped over or manipulated in any manner that the workmen mayk desire. On account of the greatY weight, from `one hundred fifty to three hundred pounds of the coil, it is very desirable to tip the reel in. order toreduce thelift in placing the coil on the reel. This canbe done in this device by liftingthe rod 39 and tipping the reel and spindle over to make it easy to put on the heavy rod or wire.

The ease of operating and manipulating the device is important, because unless-a safety device in. such mechanism requires little labor or-attention on the part of the workmen, they will neglect it after a time and not go to the trouble of placingit :in positionrand thus leave the device so that it will endanger the workmen when the wire becomes entangled, and be liable to break the wire. This difficulty is obviated by the arrangement above described which is so simple andVV easily operated that it helps rather than hinders the laborof the workmen.
