INVENTOR.
Patented Oct. 1, 1929 UNITED STATES mam emcr JOHN S. LAPP, OF LE BOY, NEW YORK, ASSIGNOR TO LAP INSULATOR COMPANY, INC.,
A CORPORATION OF NEW YORK CLAMP Application filed March 16, 1928. Serial No. 262,251.
This invention relates to clamps or supports and more particularly to devices for holding and supporting cables, wires, elec tric conductors and the like.
WVire supporting clamps of this type are generally employed in connection with a string of suspension insulators, the clamps being hung from the bottom of such a string and the associated conductor supported in the clamp.
An object of this invention is to provide an improved construction of conductor supporting clamp of the type set forth.
A further object is to provide av conductor clamp of simple form which will be cheap to manufacture and easy to install.
These and other objects which will be apparent to those skilled in this particular art are accomplished by means of the invention illustrated in the accompanying drawings in which Figure 1 is an end elevation of a line clamp constructed in accordance with one embodiment of this invention. Fig. 2 is a top plan view of the arrangement shown in Fig. 1 and Fig. 3 is a perspective view of one of the cooperating members forming the present invention.
The particular embodiment of the present invention which has been chosen for the purposes of illustration includes two cooperating body members which are of identical shape so that a single casting may be employed in producing the cooperating members of the clamp. These members are formed so as to interlock in such a manner as to prevent relative movement thereof in any direction when clamped in operative position. Their arrangement is such that a single clamping means may be employed for locking the two members in operative position, and this clamping means may be located in an accessible position below the associated conductor.
As illustrated, the clamp includes separate cooperating members 5, each of which is formed as shown in Fig. 3 and includes a body portion 6 having a horizontal row of spaced, laterally projected teeth 7 adapted to interlock with the teeth of the cooperating member so as to provide an extended seat .8 for the line orcable 9 supported thereby. 7
Above the line supporting teeth, each membe]: has an inwardlyprojecting cable clampmg projection 10 provided with projecting teeth 22 adapted to interlock with similar teeth of the co-operating member in such a manner as to force the cable downwardly between the inclined cable engaging surfaces 11 which, as the cooperating members are clamped together, cont-inue to force the cable downwardly until it is clamped against the supporting seat 8. This is best shown in Fig. 1.
Each member is provided with an 'upwardly extending perforated supporting. gear 12 positioned in offset relation to the body portion to which it is connected by an angularly extended neck 13 provided with a slot 14 for receiving the neck of the cooperatmg member. It will be apparent that the, necks 13 interlock with each other in such a way as to prevent separation of those portions of the clamping members located above the supported cable or line 9. Each neck is provided with an outwardly extending lug 15 on which is formed a boss 16 engaging a recess 17 in the corresponding lug 15 of the opposite member, see Figs. 1 and 2, for preventing relative movement between the upper portions of the separate members. Each member is provided with a depending flange 18 having one or more openings 19 for receiving locking bolts 20.
It will be apparent that the separate members are so formed that a single locking mechanism such as the bolt 20 operates to secure the members in line clamping position against relative movement in any direction. The upper portions of the members are so formed as to interlock automatically when assembled together so that the single clamping mechanism, which may be so placed as to come at one side only of the line to be clamped, holds the line supporting teeth 7 in clamping position. Each member is identical in shape with the cooperating member so that a single casting forms both parts of the clamp, and the clamp may be made in various sizes depending upon the size of wire to be supported. The clamp may be hung from the usual insulator supported hanger or from any desired support by means of the openings 21 in the supporting ears.
What I claim as new and desire to secure by Letters Patent is:
1. A line clamp including separable members provided with line clamping faces, interlocking portions on said members for securing said members against relative lateral movement and interengaging pins and recesses on said interlocking portions for preventing relative longitudinal movement of said members.
2. A line clamp including separable members provided with line clamping faces, interlocking portions on said members for securing said members against relative lateral movement and interengaging portions on said interlocking portions for preventing relative longitudinal movement of said members.
In testimony whereof, I have hereunto subscribed my name this 27th day of February, 1928.
JOHN S. LAPP.
