Description

PATENTBD DEC. 3. v1907. A. s. DEEM.
INSULATOR.
APPLICATION IE ED JULYG 1907 1 UNITED STATES PATENT OFFICE.
ARTHUR S. DEEM, OF READING, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO ISAAC BEAR, OF READING, PENNSYLVANIA.
'IULATOR.
Specification of Letters Patent.
Iatented Dec. 3, 1907.
Application filed m 6. 1907. emu No. 382.462.
To all whom it may concern:
Be it known that I, ARTHUR S. DEEM, a citizen of the United States, residing at Readin in the county of Berks and State of Pennsylvania, have invented certain new and use-' vide'for taking up the slack in the wire.
Heretofore cleats have been made with serrated grooves the surfaces of which are substantially parallel. This construction will clam the ire but will not take up any of the sack. Inmy present device I form the grooves deeper at the center than at the ends, in one of the cleat members and in the other I form corresponding or registering lugs, ad apted to enter said grooves, thus taking up a portion of the slack at each cleat while still securely holding the wire.
The invention is more full described in the following specification an clearly shown in the accom anying drawing, in Wh1Cl1I- Figure 1 s ows the meeting faces of both cleat members. Fig. 2 is a sectional view, enlarged, showing how the wire is held between the members.
The numeral 1 designates the lower cleat member. This member is formed with'one or more grooves 3 to receive the wire 2. These rooves are depressed at the center, being ee er at that point than at the sides.
he numeral 4 designates the top member.
This member is formed with a corresponding in outline, a apted number of hi s5, substantially semi-circular v to enter the grooves in the opposite member.
grooves and In s terminatin short 0 Both members are provided with the usual screw holes for securing them together and when the wire is placed. in the grooves and the members drawn together, the wire isforced into the grooves and a portion of the slack is thereby taken up. When the wire is strung and fastened at both ends, there isnecessarily some slack. When a suflicient number of my cleats are applied thereto this sleek is entirely taken up, each cleat taking up a small portion thereof.
The device may be made in any form and I do not desire to limit myself to the exact form shown. Circular or square posts may be formed with these grooves and lugs with equal facility.
Having thus what I claim and desire to secure by Letters Patent is 1. An insulating cleat for electric wires comprising two members, having plain meetmg surfaces, one ofwhich 18 provided with transverse. concaved grooves spaced apart,
the other member having integral convex lugs correspondingly s aced and adapted to enter said grooves, sair lugs and said grooves terminating within said' plain surfaces and leaving a margin on either side thereof.
2. An insulating cleat for electric wires comprising two members having re 'istering the opposite edges of the cleat, whereby clam ing shoulders are-formed at opposite sides 0 the registering grooves.
In testimony whereof I affix my signature, in presence of two witnesses.
