This invention relates to, certain newand useful improvements 111 electrlc WlIlllg? machinesparticularly vdesignedto be used c to facilitate the installation of large-, stiff, rubber-covered insulated copper wire as; re:-

quiredin the}placing of; switches, ,1ights,

receptacles, etc, in homes, factories and pubhchu ldmgs.

This wiring is generally. done-as knob and. tuhe workonby p-lacingthe wire 1n conduit Inmaking theseinstallations it is necessary to unreel the. wire frorng a .coilgand thread thewire through a porcelaintuhe placed in a holeibored through the joistor pulling. it, into (the-conduit.

Referring more in detail to. the several views, the. present invention v embodies a,. substantially rectangulan casing,- 5 with vertically swinging endldoors 6 haizing their lower: edges hinged as atfl to the ,bottom of theicasing 5.

and strength, divides the casing into two like? compartments 9 and l O an d a spindle 11] I Afcentr'al" partition 8, pret erably madeof two thicknesses of material its centrali portion mounted in the partition 8. This spindle is 7 preferably is held against,-

Any conventional formof,latch'may,

provided for holding the end doors 611 in I v closedsposition. V

A reel l3 .is removab lyhpositioned upon1 each end o fthe spindle 1l"sou that each, cdmsj partmentgofthecasing. contains areelmand each .reeli has. the large, stiff} insulated IWire- 1e Wound thereon,'one-strand of ,the;wire

Th'eseireels are of, suchilengthllas. to extendwill be 7, prevented from turning; too. fre,

and bearing against the adjacent end of the adjacent reel or spool. This brake element preferably consists of. a resilient strip of metal with one end fastened against the inner face of the door and with its other end extending inwardly to engage the adj cent spool;

The top wall of the casing 5 is provided with openings in which are fitted porcelain bushings 16 through which the wire may be threaded for convenience in dispensing the wire from the spools as required. These bushings are located in avertical plane to one side of the spindle 11 so that the wire will pass outwardly through the casin in a ready and most desirable manner. Also, to suit the requirement of special cases, the wire may be taken out through one of the side walls of the casing through the pro vision of further porcelain bushings 16 se cured in suitable openings in one side wall of the casing in a horizontal plane above the spindle 11. In order to permit convenient carrying of the device from place to place, the top wall of the receptacle has a handle 17 suitably hinged thereto by means of a retain ing plate 18 which is riveted or otherwise secured to the casing.

In operation, the end doors 6 are released ind swung downwardly so as to permit ready access to the ends of the spindle 11, and then the required spools of wire are placed upon said spindle in the compartments 9 and 10, the end doors 6 then being swung upwardly and latched in closed position, after the ends of the wire have been threaded outwardly through the desired ones of the

bushings

16 or 16. The desired amount of wire is then readily used by removing the wire from the casing by simply exerting a pull on the outer end of the wire. It will be seen that when the wire has been entirely used from the spools, they may bereadily replaced by new spools containing full amount of wire.

From the foregoing description it will be seen that the wire will be reeled off of the spools as needed in a straight and natural position so that the wire cannot become twisted or tangled and as the unused wire which is outwardly of the casing may be readily reeled thereinto, there is no danger of causing damage to or soiling of the unused wire when carrying the device from place to place.

Minor changes may bemade without departing from the spirit and scope of the in vention as claimed.

It will be seen that the chambers 9 and 10 may be formed of separate units such as would be produced if the device in Figure 1 had its top, bottom and front and rear walls severed in a vertical plane between the two thicknesses of wall of the partition 8 with the spindle 11 also severed in this plane. With such a construction the machines may be placed on the market in single units holding only one spool of wire, and if the user of the device desires to use a double unit he can bolt two of the single units together.

What is claimed is v .1. In a wiring machine of the class described, 21. rectangularcasing having hinged end doorsand provided with a central transverse partition lying parallel with the doors whenxclosed, said partition dividing the casing into a pair of adjacent compartments to which access may be had upon opening of said end doors, a horizontal spindle arranged centrally and longitudinally of the casing with its central portion passing through the partition and adapted for the reception of spools of wire upon the ends thereof" so that one spool of wire willbe located in'each compartment, and friction brake elements carried by he end doors arranged to bear against the adjacent ends of the spools when said doors are closed for preventingturning of the spools too freely upon the spindle, said casing having outlet openings for the wire from each spool.
