Referring to the drawings, my "improved cable clamp comprises} a frame member a clamping member 21. The frame anember20 is preferably formed from a single piece 'of ':-heavy sheet metal, lbent :toi U- shaped section as indicated in Fig.1'2'and having the side portions thereof. extending upwardly and spaced apart in parallel relation. The clamping member; 21 ispgrovided withaa, serrated: eccentric clamping gEaee 24:.

The threaded; sl1anl(;-3B of 30 may be extended downward; 5 as indieatedi-in-Fig'. 1; for. attachment to a trolley wire Tv ortor any: other purpose.
' The-sides ofthe clamping member. 21 are j preferably grooved, as indicated at 36 (Figs.
3a'nd 5), and spring 'pawls 38 are. struck-up fromthe sides of the frame member 20,--the 'struck-upportions being beveled .or pointed and-.bein'g'bent and displaced so that the points will project inward as indicated in Fig. 5,: so as :to engage the grooves 3.6 ingathe clam-ping'member21.

i The openings 26inthe side portions oljthe 199 Wis to be secured, 0 r in the clamp, the wire is inserted as indicated thus inserted it may be rotated 90 to the po-' sition shown in Fig. 6. It can then be swung downward to the position shown in Fig. 3
and upon engagement with a wire or cable W the pivot ortions will be raised into the slightly 0 set bearing openings26 which will determine the movement thereof.
The extreme end portions of the parts 25 "are preferably enlarged, as indicated at 47,
(Figs. 2 and 7 and these enlarged end portions are positioned outside of the side portions of the frame member 20 when the parts are in operative relation and prevent spreadmg of the sides under pressure.
In Fig. 9 I have indicated a slight simplification of my invention, in which the frame member 50 is formed with a straight bottom portion 51 and the parts are so proportioned that the attaching member 30 may be omitted.
In Fig. 10 I have indicated the use of a wedge 52, transversely concave and smooth on its under face to fit the upper surface of a lead-covered cable C and concave longitudinally on its upper face, as indicated at 54, to receive the eccentric face of the clamping member 21. I
I have thus provided. an extremely simple cable clamp which, in its essential details, comprises only two parts, the frame member 20 and the clamping member 21, the use of the attaching member 30 being optional.
The spring pawls 38 are formed integral with the frame member 20, and the grooves 36 and pivot portions 25 are formed integral with the clamping member 21. The parts are readily assembled or separated without the use of any tools and are readily secured in position by a simple blow from a hammer or other suitable tool.
Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is z- 1. A cable clamp comprising a frame mem her, an eccentric clamping member pivotally mounted therein, and cooperating locking devices on said frame and clampingmemg ber effective to prevent unlocking movement of said clamping member until said locking devices are manually rendered inoperative.
2. A cable clamp comprising a U-shaped sheet metal frame member, an eccentric clamping member pivotally mounted therepivoted axis for angular in,=and cooperating locking devices on said frame and clamping member effective to prevent unlocking movement of said clamping member until said locking devices are manually rendered inoperative.
3. A cable clamp comprising a sheet metal frame member, a clamping. member pivotally mounted therein, and cooperating looking devices on said frame and clamping members, parts of said locking devices being formed integral'with said sheet metal frame member.
4."A cable clamp comprising a framemember having inwardly projecting spring pawls, and a clamping member pivotally mounted in said frame member and having grooves infiits'side faces positioned for engagement bysaid pawls.
5. A'cable clamp comprising a frame member having inwardly projecting spring pawls formed integralv therewith, and aclamping member pivotally mounted in said frame memberand having grooves in its side faces positioned for engagement by said pawls.
6. A cable clamp comprising a one-piece frame member having spaced side portions, and a clamping member pivotally mounted therein, said clamping member beingv readily inserted and removed as a unit from said frame member. 7 H 1 7. A'cable clamp comprising a. frame memher having spaced side portions, and a clamping member pivotally mounted therein, said clamping member being readily inserted and removed as a unit from said frame member and having provision to prevent spreading of said portions when in use. Y
8. A cable clamp comprising a frame member having spaced side portions, and a clamping memberv pivotally mounted therein, said clamping member having cylindrical lateral projections and said side portions having aligned openings, said openings being elongated in opposite directions from the 4 axis of said clamping member to permit insertion of said member by a turning move-. ment thereof.
' 9. The combination in a cable clamp as set forth in claim 8, in which the outer ends ofsaid lateral projections are enlarged to preventspreading of said side portions when in use.
10. A cable clamp comprising a U-shaped frame member, a clamping member pivotally mounted between the sides of said frame member, said member having a depressed bottom portion with an opening there through, and anattaching member secured in said opening and extending outward therefrom. r
I 11. The combination in a cable clamp as set forth in claim 10. in which said attaching member'has an enlarged head adapted to support a cable against the passage 6f said. clamp. g
12. The combination in a cable clamp as set forth in claim 10 in which said attaching member has an enlarged head adapted to support a cable against the pressure of said clamp, said head being concaved to correspond to the shape of the clamping member.
13. A cable clamp comprising a U-shaped frame member, a clamping member pivotally mounted between the sides of said frame. member, and a wedge shaped member insertable between a cable and the face of the clamping member, said wedge-shaped mem-, ber being concaved transversely on its lower face to fit the cable and being concaved 1ongitudinally on its upper face toconform to the curvature of the clamping face of said clamping member.
In testimony whereof I have hereunto affixed my signature.
