9 Claims.

My present invention has for its object to produce a sturdy but relatively inexpensive fitting for connecting an electrical conductor and/r its protective covering, or two separate conductors to a ground pipe of relatively large size. The various features of novelty whereby my invention is characterized will hereinafter be pointed out withparticularity in the claims; but, for a full understanding of my invention and of its objects and advantages, reference may be had to the following detailed description'taken in connection with the accompanying drawing wherein:

Fig. 1 is a cross section on line I--I of Fig. 3 and represents a fitting installed on a pipe and with a conductor and its protective covering in position in the fitting. Fig. 2 is a view at right angles to the water pipe and looking at'the end where the conductor and its protective covering enter the tting. Fig. 3 is a plan view and Fig. 4 is a section on line 4-4 of Fig. 3.

Referring to the drawing, I is a body member or yoke which is of somewhat greater length than the diameter of the largest pipe on which it is to be installed. 2-2 represent U bolts having' threaded ends which pass through apertures'in the body member or yoke.l 3-3 are clamping tive covering to the yoke. 'I'hese clamping plates have apertures aligned with the apertures in yoke I and through which the U bolts extend. 5-5 are threaded nuts on the U bolts and which, when tightened, clamp the conductor and/or its protective covering to the fitting and also clamp the fitting on the pipe.l The portion of body member or yoke I lying between the clamping plates 3-3 is of channel formation as shown Vin Fig. 4. 'Inis formation permits the body member or .yoke to be formed with a seat for the pipe as shown at 'l and in fact the bottom of the channel may be cut entirely away as shown by the dotted line 8, the yoke still having sufiicient strength, because of the channel formation, to resist bending. The channel also serves to protect the conductor against mechanical injury or disturbance.

'I'he yoke, directly beneath the clamping platesl is formed into seats for the reception of the conductor and its protective covering the seat for the conductor being shown at 9 and that for the protective covering at I0 it being of, the same 'formation as seat I2. The plate 3 is invertible and one side is formed with a seat II for the conductor and the other side with a seat I2 for the conductor covering. In Flg. 2 the plate is shown clamping the conductor covering while in Fig. 4 itis shown clamping the conductor.

Since U bolts suitable for any size of pipe are readily obtainable and inexpensive and since the only change necessary in the fitting to adapt it to pipes of practically any size is to increase the length of the yoke I thisdesign is particularly advantageous for a fitting intended for the larger sizes of pipe. The construction of the clamps for the conductor and its coveringwhich provides a clamping bolt at each side of the clamped member, adds greatly to the effectiveness of the clamp. v

While the drawing shows a conductor with a protective covering, it will be clearly seen that a conductor without any protective coveri g may be attached with equal facility the co ductor y itself being preferably clamped under both clamping plates or each plate may clamp a separate conductor. Y

While I have illustrated and described with particular-ity only a single preferredform of my invention, I do not desire to be limited to the exact structural details thus illustrated and described but, intend to cover all forms and arrangements which come within the definitions of my invention constituting the appended claims.

What'I claim is:

1. A fitting for connecting an electrical conductor and its protective covering to -a ground -pipe which includes a pair of threaded U bolts spanning the pipe andspaced apart in parallel formation, a yoke for the U bolts the yoke having a pair of apertures in each end through which the legs of the U bolts pass, a pair of clamping plates each plate having two apertures alined with the apertures in one end of 'the yoke and through each of which one leg of each of the U bolts passes; and a nut on each leg of each bolt and on the outside of the clamping plates for drawing the yoke against the pipe and each plate toward the yoke, f'or clamping to the yoke, by each plate selectively, a conductor or afconductors protective covering selectively.

y 2. A fitting for connecting an electrical conductor` and its protective covering t0 a ground pipe which includes a pair of threaded U bolts spanning the pipe and spaced apart in parallel formation, a yoke for the U Vbolts the yoke having a pair of apertures in each end through which the legs of the U bolts pass, a pair of clamping plates each plate having two apertures alined with the apertures on lone end of the yoke and through each of which one leg of each of vthe U bolts passes; and a nut on each leg of each bolt and on the outside of the clamping plates for drawing the yoke against the pipe and each plate toward theyoke, for clamping to the yoke, by each plate selectively, a conductor or a conductor protective covering selectively, and a seat for a conductor protective covering `formed in the yoke substantiallyl at right angles to the pipe and positioned between at least one pair of bolt apertures in the ends of' the yoke.

' 3. A :titting according to claim 2 characterized by the further fact that it includes a seat for a conductor positioned in the center of the seat for the protective covering.

4. A fitting for connecting an electrical conductor and its protective covering to a ground pipe which includes a pair of threaded U bolts spanning the pipe and spaced'apart inv parallel formation, a yoke for the U bolts the yoke having a pair of apertures in each end through which the legs of the' U bolts pass and a seat for a conductor and a seat for a conductor protective covering positioned between eachpair of apertures, a clamping plate having two apertures for the reception of corresponding ends of the U bolts and a second plate havingl apertures for the other corresponding ends of the U bolts and a `nut on each end of each holt and on the outside of the clamping plates for clamping the conductor between one plate and the' yoke and for clamping the protective covering between the other plate and the yoke and for clamping the yoke against the pipe.

5. In a tting for connecting a grounding conductor and its protective covering to a ground pipe; a rigid metal member for contacting the pipe the member having portions extending beyond the pipe on oppositeV sides thereof said portions being substantially parallel and in the same plane and each of said portions having apertures, substantially at right angles to the plane of 'the portions, for the reception of at least two clamping bolts; bolts in the apertures and protruding therefrom in the direction away from the pipe, the bolts on one side of the pipe being attached to the bolts on the opposite side of the pipe by a member positioned against the pipe on the side opposite the rigid member; a conductor clamping plate positioned on the protruding porti ns of the bolts on one side of the pipe' and a c ductor protective covering clamping plate positioned on the protrudingportions of the boltson the opposite side of the pipe; and nuts on the bolts which when tightened clamp the conductor between 'on'e plate and the rigid member and clamp its protective covering between the other plate and the rigid member and clamp the rigid member on the pipe. f

6. A tting for connecting an electrical conductor to a ground pipe which includes a rigid 'body member abutting the pipe and extending beyond the pipe on each side thereof, a conductor clamping plate positioned above each extension, the portion of the body member lying `between the plates being of channel formation for the vreception oi.' the conductor; together with means for fastening therigid bodyv member to the pipe and for clamping the conductor between the plates and the body member with the conductor in the channel.
