TEST-CLAM P.
Patented Feb. 13, 1906.
Applic ation filed Debemher 19, 1904. Serial No. 237,487-
To all whom it} may concern.-
Be it known that I, THEODORE NAGEL, a citizen of the United States, and a resident of Chicago, in'the county of Cook and State of Illinois, have invented certain new and useful Im rovements in Test-Clamps, of which the fol owing is a full, clear, and exact description.
My invention relates to what is known as test-clamps, which are used extensively by electricians, especially in telephone-circuits, for clamping wires or ends of Wires together.
Wires of different sizes or diameters are used particularly in telephone work,and it is oftentimes difiicult with the means at present available for that urpose to clamp them together, and even w ere this can be satisfactorily accomplished when the clamp is loosened it will fall off of the wire.
The object of my invention is to provide a simple and effective clamping device for securing the ends of two or more wires of the same or different diameters together which will not accidentally fall off of the wires when it is loosened to permit the withdrawal of the same. This I accomplish b the means hereinafter fully described, an as particularly pointed out in the claims.-
In the drawings, Figure 1 is a perspective view. of my invention, drawn to an enlarged scale and showingFportions of severalwires secured therein. 1g. 2 is an end view thereof. Fig. 3 is a transverse section vtaken through the centerof length of the clamp. Fig. 4 is a similar view of a modified construction of my invention. Fig. 5 is a lan view of the outer clamping-plate thereo Fig. 6 is a perspective view of the innermost clampin -Flate.
y invention comprises a holder A, which consists of a short channel-shaped piece of metal, clamping-plates B and C, respectively,
and a eculiarlyrconstructed clam ing-screw D. T ese clam inglates are 0 the same length, but of si ht y less width than the channel of the hol er A, and are of such thickness that when wires of the largest ga e are clamped by the same the uppermost p ate B will not have its outer or ex osed surface raised above the edges of the si e walls of the k holder. .The lower plate has the lower angles of its side edges undercut or beveled; so that when wires are laid lengthwise in the an gles of the channel of the holder it will crowd tion I have provided screw, substantially as' shown.
and clamp said wires into said angles orcorners as it is pushed downward toward the bottom of the holder. The up er surface of the plate O is preferably provi ed with longitudinal grooves arranged one on one side and the other on the other side of the plane of the clampin -screw and are adapted to seat therein t e wires 0 0, either of the same or different diameters than the wires 1) b, hereinbefore referred to. The screw D extends down through enlarged o enings as :1; in the center of the plates B an O and is tapped into the bottom of the holder A, and in order that either one or both of the plates B and C may have a slight tilting movement in any directhe shoulders of the head of the screw D with a convexed bearingboss (1, the curvature of which substantial y corresponds to the circumference of a sphere whose center is intersected by the axis of the This bear.- ing-bossis seated in the countersunk edges e of the adjacent end of the enlarged opening a:
' of the plate B, which forms the bearing-cup therefor, and when the screw is turned so as to cause the lates to clamp one or both of said plates W1 1 tilt,- so as to automatically accommodate their position to and equalize the ressure u on wires of different gage clamped etween t em, substantially as shown in the drawings. p
If desired, the depth of the holder may be increased substantially as shown by the holder E inFig. 4, and instead of two plates three (,2 g h) or more may be used. In this event t e intermediate plate q corresponds in dimensions'to the outermost plate f, except that it has longitudinal grooves k 7.: in its upper surface the same as in the lower plate It and exce in -cup t erem.
