connucron SUPPORT.
Application filed September 26, 1923. Serial No. 664,885.
The object of my invention is to provide a device as stated above which is particularly adapted to use in mines where the mineroof is low and it is desired to place the trolley conductor as'near the roof as possible with safety, and this object is ac complished by producing a device of as little vertical height as possible, consistent with requirements of strength, insulation,'
etc., andto so place'the supports secured to the device, and by means of which it is secured to the roof supports, that the upper edge of thedevice can be brought into close proximity to the mine roof. My invention resides in the new and novel construction, combination and relation of the various parts hereinafter more fully described and shown in the accompanying drawing.
In the drawing:
Figure 1 is a top plan view of my invention.
Fig. 2 is a side view in elevation. Fig. 3'is an end View.
Fig. 4 is a longitudinal sectional view of the attaching means for securing the de vice to the overhead supports and is taken on the line 4+4: of Fig. 1.
Fig. 5 is a sectional view on the line 5-5 ofFig. 4.
In the preferred form of the construction embodying my invention I employ an insulating member 1, preferably of'wood', although other insulating material, such as fiber, etc., may be used. To the ends of the member 1 I secure connecting members 2 secured to the member 1 by means of the bolts 3 and each provided with a longitudinally extending recess to receive the ends of the trolley wire 4: which is held in the recess by means of the set screws 5. The inner ends of the connecting members 2 are spaced apart and the space between the ends is filled with an insulating runner piece 6,
the lower surfaceof which conforms to the lower surface of the members 2 thereby giving a smooth andunobstructed path for r the current collector. Other means maybe used for the member 6, such as a metal-run ner piece spaced from the members'2 or 'a pivoted member-whichmay be moved into, or out of position between the members 2. .The device is provided with brackets 7, one at eachend by means of which it is supported from the roof by means of well known roof supports such. as insulated hangers held in place by lag screws, expansion bolts, etc. The brackets are secured to the member 1 by means of the bolts 3. In order to support the device as near the roof as possible the projecting ends of the brackets 7 are set low upon the device, so. that they project longitudinally. at a point between the upper and lower face of the member 1. It has been the custom in the pastto mount the means by which the device is supported from the-roof to the upper face of the member 1 either at the center or atthe ends, but this method means a greater distance between the trolley wire etand the roof. of the mine, which is -objectionable To'overcome this defect, I-have so mounted the brackets 7 that the upper edge of the member 1' may be positioned above the'up per edge of the outer ends of the'brackets 7.
Theend of the bracket 7 is provided with a novel construction, in that the bracket is provided with anielongated slot 8 in which is loosely mounted a rotatable and slidable nut 9. The nut is provided with a threaded recess 10 by means of which the nut is secured to the roof support by rotation of the nut 9. To secure the nut 9 to the member 7 the upper endof the nutis provided with a thin annular flange or lip 11 which originally stands upright. A washer 12 of the shape shown is placed in position as shown,
together with the member 9, and by suitable tools the annular flange or lip 11 is rolled outwardly, therebylocking the members 9 and when such is the case it is a difficult and expensive matter to properly secure the device in place. If desired, the slot 8 ma be made a circle thereby permitting lateral, as well as. longitudinal adjustment.
By giving the upper end faces of the member 1 a greater bevel and by properly shaping the bracket member 7, the projecting end of the member 7 can be brought still lower, in fact, as low as necessary clearances betweenthe members 9 and 5 will permit.
M d fi at ons w l ead y ue'st hemselves to others skilled in the art, therefore, I do not wish to be limited otherwise than by my claims.
