NEWTON JACKSON, OF NEWPORT, RHODE ISLAND,
Application filed February 21, 1924, Serial No. 694,338.
To all "whom t may concern.'
Be it known that NEWTON Jamison, a citizen ot the United States, residing at Newport, in the county ot Newport and State ot Rhode Island, has invented certain new and useful Improvements in Wirc Clamps, ot which the following is a specitication.
This invention relates to the general art ot clamps and has more particular reference to a clamp that is generally designed to be used in making wire connections and more particularly for use where secondary over head electric service wires are tapped to secondary mains which are run on racks along a street.
The primary object of thc invention resides in the provision oi a clamp of the above character wherein two wires that cross at substantially right angles to each other, may be rigidly connected together and this without the usual necessity of soldering the same, the nature of this clamp being such as to rigidly connect two wires ot dilierentsizes and to make a permanent contact between the two wires.
A still further object is to provide a clamp of the above character wherein two cross wires may be joined together without the usual slow process of making wrapped joints and further the invention is such as to enable the. clamp to be employed in the connection ot wires ot varying sizes.
With the foregoing and other objects in view, as the nature of the invention will be better understood, the same comprises the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.
In the drawing wherein like reference characters indicate corresponding parts throughout the dilerent views:
Figure 1 is a view partly in end and partly in side elevation of a clamp constructed in accordance with the present invention, the same being shown as actually employed in the connection of two cross wires,
Figure 2 is a top plan View thereof,
Figure 3 is an edge elevational view of one of the clamp members per se, and
Figures 4f and 5 are plan views of the inner sides of the two clamp members comprising the main elements ot the present invention.
Now having specific reference to the drawing, my novel crossed wire clamp emr bodies the provision ot two identically shaped clamp plates 55 ott any suitable metal and being ot general oblong shape as 6 clearly shown in Figures 4. and 5.
Adjacent the opposite ends of cach ot these clamp members, the same is formed with circular' openings 6-6 whereby said clamp members may be joined together in .face to face relation through the medium ot bolt and nut connections designated generally 7 Y In addi-tion to these openings 6-6, each clamp member 5 is 'formed upon its inner 70 face with a diagonally extending relatively deep and wide V-sha-ped channel `8 that opens at its opposite ends at the side edges of said clamp plates.
It will be readily appreciated that when these two clamp members 5 5 are placed in face to face contact with each other, the channel 8 in each clamp will extend at direct right angles to the channel of the cooperating plates and in actual use, the cross wires A and B are disposed within the channels o'f the corresponding plates 'to entend at direct right angles to each other as clearly shown in Figures l and 2 and to be subsequently rigidly joined together at their P55 point of crossing by tightening up upon thc nut of the bet'orementioned bolt and nut connections indicated generally at 'i'.
From the foregoing, it will be apparent, that I have provided a highly novel, simple and ecient forni ot wire clamp and one that is well adapted for the rigid connection of a pair of cross wires of widely varying sizes and this without the usual necessity ot providing a wrapped joint or other torni of soldered connection between said wires and one that will e'liect an electrical connection between the wires in a manner as eiiicient as said wrapped or other form ot' soldered joint.
I do not wish to be limited to the specilic shape of the clamp plates 5 5 shown in the views nor the material from which they are formed in view of the fact that in the future practice the shape of these plates may be varied as well as the material from which they are formed without departing from the spirit and scope of the appended claim.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: e
A clamp device for cross wires comprising i pair of plate members, sid members being of the seme' conignrttiion and the same relative dimension, each member having parallel side edges and provided in the Vicinity of its ends with circular openings located midway between the parallel side edges, each member being provided at one of its faces with a channel having its side edges disposed at acute angles to the side 'edges of `the member, 'said channel being lo- 10 'cated between the openings, and the edges of the channel intersecting the edges of the openings at the inner portions thereoftl and a pair of traction bolts passing through the openings of the members and disposed one 15 at eaehside of botho1 the channels.
In testimony whereof I aiix mv signature.
