TERMINAL CLAMP.

Specification of Letters Patent. Patented Aug, 29, 1916.

Application filedMarch 3,1914. SerialNo .822,196.

T 0 all whom it may concern.

Be it known that I, KARL A. SIMMON, a citizen of the United States, and a resident of \Vilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented'a new and useful Improvement in Terminal Clamps, of which the following is a specification.

My invention relates to clamping devices for wires or cables, and it has particular reference to such clamps as are adapted to support and secure stranded electrical conductors and cables in position.

The object of my invention is to provide a simple. and inexpensive structure" of the above indicated character which may be readily assembled and manipulated and which shall effectively perform its intended functions.

Another object of my invention is toprovide a device of this general class which shall embody means to restrain lateral movement of the cables and prevent them from being squeezed out of shape, and, furtheigg) provide adequate means for locking the. parts in position to prevent relative turning movements. V

In the accompanying. drawing, Figure 1 is a view, partially in section and partially in side elevation, of a device co structed in accordance with my invention/fig 2 is a view in end elevation of my invention, Fig.

3 is a view, similar to Fig. 1, of a modified form of my invention, and Fig. 4 is 'a view similar to Fig. 3, of a still further modification of my invention.

Referring to Fig. 1 of the drawing, the device shown comprises a channel member 1 having substantially parallel sidearms 2, and an angle member 3 provided. with an arm 4 which is disposed in parallel relation to the main body portion of the channel member .1 and is interposed between the channel arms 2 in such manner as to prevent relative turning movement between the cooperating members. a

A bolt 5 projects through openings in the arm 4 and the body portion of the channel member 1, and its outer end is provided with a suitable washer 6 and a nut 7. The bolt 5 has a head 8 which is so disposed as to engage an arm 9 which forms an integral portion of the angle member 3, whereby turning movement of the bolt 5 is prevented.

As shown, cables 10 are located between the cooperating angle and channel members 3 and 1 and on the'respective sidesof'the bolt 5, and it is obvious that said cables may be firmly fastened or clamped 'in position by turning the nut 7 in. the usual manner; -50

Reference may. now be had to Fig 3 in which the angle member? is provided with an extension 12 which 'is substantially par allel to the arm Wand thus forms a member of substantially Zshap e." The channel member '1 hasf'its' mire materially longer than its other parallel arm 2*, and said a'rm 2 projects downwardly and engagesfthe arm 9? of the angle member The other arm 2* projectsdownwardly on the outside of the extension 12, and, in this manner,

relative movement between the two members is prevented, while the "conductors or wires 10 are" restrained against lateral movement.

The bolt 5project's th rough'both of the members 1 audit" andfhas its head 8jijn' engagement with the arm to prevent turning thereoff f Ai utT is 'provided'jt o cooper-l ate with the l v f In Fig. t the'devi'jce shown i'ssimilarto that shown in Fig 3,.but'the'j anglefmenig ber 3 is; provided 'withanjextension 12? which is of somewhat" greater length, while the cooperating clamping memberv 1?. has

. but a single arm 2 which engages the side of thearm 9 for preventing relative movement between the members. The. bolt 5 has its head 8 in engagemen't with the extension 12 and a nutjycotiperateswith the lower end of the'bolt,

The angle members 3 and 3 are provided for attaching the terminal members to electrical devices. (not shown). .The arms 9 and 9 may be either soldered to the electrical devices or clamped thereto by any of thewelllmown methods.

I do not wish to be restricted. to the specific structural details and arrangement and location of parts, set forth, as many modifi cations therein may be effected without departing from the spirit and. scope of my invention, and such modifications are intended to be covered by the appended claims. e

I claim as my invention 1. A clampingdevice comprising an angle member having two arms, a channel member adapted to straddle the'said-arms, and a bolt adapted to project through the said members and having its head re strained in position by the said angle member.

2. A clamping device comprising a channel member. having side arms, an angle member having a plurality of arms, one of one of the arms of the' arms being disposed in parallel relation to the middle portion of the said channel member and between the side arms thereof, and a bolt adapted to cooperate with the said angle member and the said channel member, the'head of the said bolt being locked in position by an arm of the said angle member having parallel relation with the side arms of the said c-hannel'memher. I

3. A clamp ng dev ce comprising a main member of Z-shape and a cooperating member of U-shape adapted togri'p a conductor,

said members being adapted toprevent lat eral movement of the conductor, and a bolt for clamping the said members together and having its head restrained in one position by one of the end 'portions of the Z-shaped member. 7 e

5 4. A clamping device comprisinga main nel memberhaving parallel side arms, a co operating Z-shaped member disposed between said arms and adapted to prevent a turning movement of said channel member, and a bolt engaging said cooperating members and having a side-of its head in engagement with one arm of the said Z-shaped member to preventturning of the bolt.

In testimony whereof, I have hereunto subscribed my name this 27th day of Feb. 1914.
