UNITED STATES PATENT OFFICEQ LEON O. GORELL, F KALAMAZOO, MICHIGAN, ASSIGNQR OF ONE-THIRD T0 I-IIRAM D.

SWAYZE, OF KALAMAZOO, IJIICHIGAN.

moon To all whom it may concern:

Be it known that I, LEON O. CORELL, a citizen of the United States, residing at Kalamazoo, Michigan, have invented certain new and useful Improvements in Tools, of which the following is a specification.

This invention relates to improvements in tools. a

My improved tool is especially designed by me for use in stringing or placing electric circuit wires.

The main objects of this invention are: First, to provide an improved tool which facilitates the placing or stringing of electric circuit wires. Second, to provide an improved tool having these advantages which may also be readily adapted as an adjustable boring machine or tool. Third, to provide an improved tool for use in wiring, which is simple in structure and operation and very convenient to use.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a side elevation of a structure embodying the features of my invention, the driving chain being omitted, and a part of the shaft broken away, it being shown with the chuck 5 in the holder socket. Fig. II is a side elevation looking from the right of Fig. I, the adjustment of the holder member 3 beingindicated by dotted lines. Fig. III isa detail side elevation partially in vertical section, with the chuck 5 removed, and an insulating knob or wire support and wire in the holder. Fig. IV is a detail view partially in longitudinal section, on a line corresponding to line 4-i of Fig. II. Fig. V is a detail elevation of the chuck 5; Fig.

Application filed February 28, 1913. Serial No. 751,298. r

VI is a side elevation of the bit 28., Fig. VII is a transverse section on a line corresponding to line 77 of Fig. IV. Fig. VIII is a plan view of the holder member 3. Fig.

IX is a transverse section on a line corre-' sponding to line 9-9 of Fig. III, the base portion 6 of the knob or wire support being removed. Fig. X is a transverse section on a line corresponding to line 10-10 of Fig. IV.

In the drawing, similar reference charac- "ters refer to similar, parts throughoutthe several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawings, the shaft 1 is provided with arms 2 at its upper end. The shaft is, in practice, adjustable so that the piperator may support the tool from the cor. shaft form no part of my present invention, I have not illustrated the same herein. The holder member 3 is provided with a socket l adapted to receive a wire support or insulating knob, as shown in'Fig. III, or a chuck 5, as shown in Figs. I, II and IV. Theinsulating knob or wire support shown, consists of the base portion 6 and cap portion 7, which are grooved at 8 to receive a wire, as

9, the cap section being secured upon'the base section and both secured to'the wall by a screw 10 arranged longitudinally therethrough as shown. The wire support or in sulating knob shown is of the well-known commercial type. be readily adapted for other'forms" of wire supports as might be desired. The holder member is slotted at 11 to receive the wire 9 so that the wire is arranged in the grooves The holder member can As the adjustment features of the and the screw inserted through the support, :1

and thus assembled, the parts drop into the holder. See Fig. III.

To assist in supportlng the wire and renderit more easy-to draw tight with the parts assembled and in position to be attached, the

holder is provided with laterally projecting grooved arms 12 alined with the slots 11. The arms 12 are provided with a supporting ring 18 which is sleeved over the holder, "as

shown, the sleeve resting upon the shoulder 1%, and being retained on the holder by the chuck retaining screw 15, the chuck being provided with an annular groove 16 into which this screw projects. See Figs. IV and V.

The holder is carried by the support member 17 having laterally projecting ams 18 disposed between the arms 2 of the shaft. The member 17 is adjustably supported by the screws 19 arranged through the arms 2. One of the arms 18 is adapted as a bearing for the driving gear 20. This driving gear is arranged in mesh with the driving gear 21 on the end of the spindle 22. The spindle 22 is provided with a screw driver blade 23 adapted to engage the screw 10, as shown in Fig. III. The spindle is provided with pin-like driving members 24: adapted to engage jaws formed by slots 25 in the chuck so that when the chuck is inserted in the socket it is in driving engagement with the spindle. The chuck is chambered at 26 to receive the screw driver blade. In Figs. I, II and IV, I have shown the chuck with a screw driver 27 secured therein. It will be understood that any desired tool may be arranged in the chuck, and in Fig. VI, I illustrate a bit 28 designed to fit the chuck. The driving gear is provided with adriving sprocket 29 for the driving chain 30. Further details of the driving means are not illustrated as they will be readilyunderstood.

My improved tool is adapted for boring or for other work, and is adjustable so as to be operated in various positions, as on ceilings, side walls, corners, between studding or the like, and may be operated mainly from the floor so that the work is rendered easier and may be more rapidly performed.

I have illustrated and described my improvements in a simple and practical embodiment in which I have used the same.

While I am aware that various modifications are possible, I have not attempted to illustrate or describe such modifications as I believe the disclosure made will enable those skilled in the art, to embody my inventions as conditions or circumstances may dictate, and I desire to be understood as claiming my improvements specifically in the form illustrated as well as broadly within the scope of the appended claims.

Having thus described my invention what I claim is new and desire to secure by Letters Patent is:
