ELECTRIC-WIRING?. MACHINE,;

Application, filed February 19, 1923. Serial Np, 620,107.

after more fully described. shown in - the 55 accompanying , drawings and claimed;.

In the- drawings, wherein., like reference... characters . indicate corresponding . parts throughout the several, views,.

.Figure 1 is, a substantially: central Io,ngi- 60 tudinal, vertical sectional view of. a .wiring machine constructed in, accordance with, the , present invention;...

F igure :2 is a vertical, t: ra ns verse sectional,. view, taken substantially upon, line , 2—2 of, 65 Figure 1;

Figure 3 is,. a top,, plan view of t he device. shown in, Figure 1;

Figure 4 is. a, fragmentary perspective, view of. one. of the ·.en d, doors, and, its friction.. 70 . brake member.

Referring more in detail to. the several views, the. present invention... embodies, a substantially rectangular;, casing, · 5 with, , ·. vertically swinging end doors 6 haying, their.: 75 lower edges hinged as, at, .7, to· the .bottom of the, casing 5. A, central, partition 8, _t pref-: erably made of two. •thicknesses of material,. as shown so as to be of. extreme .durability, and strength, divides .the casing into, two like so compartments 9 and 10,, and. a spindle, IT, is arranged longitudinally and.centrally of the, casing ,5. in, a horizontal ..position- with.,, its central portion mounted in the partition. 8. This. spindle is. prefer ably held against 35. longitudinal· displacement so that the extreme end, edges of the spindle will:be. main?; tained . in, the .same · vertical'., plane transversely of the. casing as ...the. end; edges of the. side walls',, of.· the casing,, by. means.of. ⁰⁰collars 12. suitably secured on- the sp.iud.le -and engaging opposite .sides of the partition 8. Any conventional form,of. latch may. be. provided; for holding .the,. end doors . 6· in . . closed position. 9.5

A reel 13.. is removably, positioned; .upon . each end of.the spindle .11. so that each com-.; partment of the. casing, contains a reel .and each .reel. has. the large; st iff, insula t ed wire.. 14 wound thereon, one strand of the wire ΐοθ being,, provided . for,· each,, spool or. , reel. These,reels are of such length as to extend from, theipajtitio.n.to, -the adjacent, end door so- that,, said, ...door, will retain the .adjacent reel upon the spindle and the. reel or spool 105 will be prevented from turning too freely, upon · the spindle. by .means of. it. friction brake member 1.5 fastened.to· each end door

To all. whom it:may concern:

Be it. known that we,. George.; L·.. Clark and Clarence IE Tibado, citizens of the United, States,, .residing, at. Norfolk, in the 5 county, of Madison and State of, Nebraska, have invented certain., new. and useful. Improvements in?Electric-Wiring Machines,, of which, the, following- is a specification, reference being., had, to. the . accompanying 10 drawings,.

This invention relates to,certain new and, useful improvements in, electric wiring, machines .particularly, designed, to be used to facilitate the installation of large, stiff, 15 rubber-covered insulated, copper wire as. required in the . placing, bf; switches,.. lights,. receptacles, etc., . in homes, factories. and public.buildings.

This, wiring, is. generally: done as knob and, 20 tube work or by placing the wire in conduit.In making these?,installations it is necessary •to. unreel the. wire: from;. a coil·.; and, thread, the wire through-a porcelain tube placed- in,, a hole? bored through the joist, or pulling 25 it into the- conduit . As the wire is placed on the market, at. the , present time in coils, it is necessary to place, the coil, of wire on the, floor,· some- distance, away, from, the, work,. We have found that, it is impossible to take 30 wire,, from these, coils laying_; on the floor, without getting kinks in the-wire, or getting,. the _twire twisted or tangled. This.is, especially true when two or more wires are t aken from, separate coils, at, the same time and 3S brought , into, .the.· same, opening,:

With, the, .use- ,of .the,-present invention the. diSieulty. of tangled·, wires?is.avoided as. the ·,wire.is·reeled oil of,spools:as. needed -in a straight and-natural position.

Another object, is to provide the wire, with graduations- whereby- the- electrician, may,, readily determine;· .the . amount, of . wire, used, on a given job.

A- further ·. object of the invent ion is, ip... 45 provide a wiring.machine of the,above- kind . which provides a convenient . means ·, for, carrying, the wire, from one point:to another,, so- that the wire cannot become tangled.,, soiled or damaged50 With; the; above general obj ects -in·, -viewj and others that will,become apparent-,as,the, natur.e_:of,the,inyenti.Qn,is,better:understQodL the. same consists in the. novel, form, com-: bination and arrangement of parts herein1,474,580 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 5 inner face of the door and with its other end extending inwardly to engage the adj acent spool.

The top wall of the casing 5 is provided with openings in which are fitted porcelain 10 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 a. vertical plane to one side of the spindle 11 so that the wire 15 will pass outwardly through the casing 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 Avails of the casing through the pro20 vision of further porcelain bushings 16^a secured 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, 25 the top wall of the receptacle has a handle 17 suitably hinged thereto by means of a retaining plate 18 which is riveted or otherwise secured to the casing.

In operation, the end doors 6 are released 30 ind SAVung downAvardly 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 35 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^a. The desired amount of wire is then readily used by removing the wire from the 40 casing by simply exerting a pull on the outer end of the wire. It will be seen that Avhen the wire has been entirely used from the spools, they may be readily 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 50 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 be made Avithout departing from the spirit and scope of the invention as claimed.

It will be seen that the chambers 9 and 10 may be formed of separate units such as 60 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 65 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 de’vice desires to use a double unit he can bolt two of the single units together. .
