UNITED STATES PATENT OFFICE.

CABLE-CLAMP.
Specification of Letters Patent.
Patented Jan. 18, 1921.
Application filed June 17, 1919. 7 Serial No. 304,877.
To all whom it mwy concern:
Be it known that we, CHARLES W. KEMPEB and J OHN T. KEMPER, citizens of the United States, residing at Oakland, in the county of Alameda, State of California, have invented a new and useful Cable-Clamp; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The invention relates to clamps and has for its object to provide a clamp particularly adapted for clamping overlapping ends of cables within a sleeve, and to rovide the ends of said sleeve at opposite sides of the cables with chambers having their outer walls formed at'an acute angle to said cables forming a contact surface for jamming rollers which are adapted to jam be tween the walls of the chambers and the outer faces of the cables, said cables by a means of said rollers being prevented from longitudinal movement and at the same time the said rollers forcing the strands of the cable into interlocking positions.
A further object is to provide the side faces with apertures through which the rollers may be placed within the chambers and through which said rollers may be removed, also to provide the outer ends of the chambers with walls for preventing the rollers from dropping out of the open ends of the body member.
A further object is to provide apertures in the body member and in alinement with said rollers, thereby allowing the insertion of an instrument for breaking the jam of the rollers, thereby releasing the cables.
A further object is to form the end walls at opposite sides of the body chamber in parallel relation to each other and their inner ends in substantially vertical alinement, said inner ends merging into roller chambers at each end of the body member.
With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.
In the drawings 2 Figure 1 is a perspective view of the clamp showing the same applied to overlapping cable ends.
Fig. 2 is a longitudinal sectional view taken on line 2-2 of Fig. 1.
Fig. 3 is a vertical sectional view taken on line 3-3 of Fig. 2.
leferring to the drawings; the numeral 1 designates the body member, which body member is preferably cast in one piece of any kind of metal desired. The body member 1 is formed with chambers 3 and 4 at its ends. The chambers 3 and 4 have one of their walls 5, which are on opposite sides of the body member from each other in parallel relation to each other, their inner ends terminating substantially in vertical alincment with each other, said walls 5 being preferably provided with indentations of standard size and of standard pitch for the reception of the strands of standard cables. The walls 5 merge into wall 6 which are at acute angles to the ends of the cables 7 and 8. The Walls 6 form triangular shaped roller chambers 9 for the reception of rollers 10, which rollers 10 are adapted to contact with the walls 6 and the cable adjacent the roller chambers 9. The outer ends of the walls 6 are provided with inwardly extending portions 11, which prevent the rollers from coming out of the cable openings 12, that is when the cables are in position within the body member.
When it is desired to clamp the overlapping portions of cables, the cables 7 and 8 are passed through the body member until they assume positions similar to that shown in Fig. 2, then rollers 10 are placed within the chambers 9 by passing the same transversely through the apertures 13 in one of the walls of the body member. It will be seen that the roller will be prevented from dropping out of the body member by the inturned walls ll. The rollers 10 being within the chambers 9 are then forced inwardly toward each other until their peripheries engage the wall 6 and the cables, then as the strain on the cables is in the direction of the arrows a and b, said cables will be prevented from moving or slipping by said rollers, which will cause the cables to be thoroughly jammed against each other at both ends of the body member and also against the walls 5 of the chambers 3 and 4, thereby providing a double jamming of the cable upon each other and also in relation to the walls 5 of the chambers 3 and 4. By terminating the u'alls of the chambers 3 and :l at a point substantially in vertical alinement with each other, it will be impossible for that portion oi the cables 7 and 8 which is disposed be tween the rollers 10 to acquire slack if the strain is temporarily relieved from the rubles. l t also prevents any slack between said rollers when placing the clamp in position. When it is desired to remove the damp a tool or drip pin may be inserted in the apertures 14:, which apertures will guide said drip pin into contact with the rollers 10 so that said rollers may be driven toward the ends the chambers and the jam on the rope broken. W hen it is desired to remove the rollers from the chambers 3 and 4, an id strument may be inserted through the aperlures to for facilitating the removal of the rollers through the apertures 13.
The invention having been set forth what i claimed as new and useful is:
l. A cable clamp comprising a body menihcr, said body member having a chamber extcnding longitudinally therethrough for the reception of cables, triangular shaped porkcts in communication with the longitudinal cluunber, the apexes of said triangular shaped pockets extending toward each other, the enlarged ends of said pockets being substantially closed, apertures in the side walls of the body member and in communication with said pockets, rollers adapted to he passed through said apertures and into jamming positions within the triangular shaped pockets and apertures in the walls and in communication with the pockets and so po sitioned that a tool passing through the same would engage the rollers thereby providing means whereby said rollers may be released.
' A cable clamp comprising a body meniher, said body member having a chamber extending longitudinally therethrough for the reception of cables, triangular shaped pockin communication with the longitudinal chamber, the apexes of said triangular shaped pockets extending toward each other and terminating substantially centrally of the longitudinal chamber, the enlarged ends of said pockets being substantially closed, apertures in the body member and in communication with the pockets, and rollers adapted to be passed through said apertures and into jamming positions in the apexes of the triangular shaped pockets when cables are disposed in said longitudinal chamber.
3. A cable clamp comprising a body memher, said body member having a chamber extending longitudinally therethrough for the reception of cables, triangular shaped pock- (is in communication with the longitudinal chamber, the apexes of said triangular shaped pockets extending toward each other, the enlarged ends of said pockets being substantially closed, apertures in the side Walls of the body member and in communication with said pockets, rollers adapted to be passed through said apertures and into jamming positions Within the triangular shaped pockets. apertures in the Walls and in communication with the pockets and so positioned that a tool. may be passed through the same for breaking the jam of the rollers, and apertures for the reception of a tool for orcing the rollers through the first mentioned apertures in communication with the po kets.
lo testimony whereof we have signed our names to this specification.
