INSULATOR AND CLAMP FOR USE IN ELECTRICAL WORK Filed oct zo', 192s Patented' June 23, 1931 UNITED STATES PATENT oF-FlcE EDWARD F. HOGAN, OF CHICAGO, ILLINOISASSIGNOR T0 Q. R. S. DEv VRY CORPORATION, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS INSULATOR'AND CLAMP Fon USE 1N ELECTRICAL Woax Application led October 20, 1928. Serial No. 313,916.
My invention relates to clamping devices and has for its object more particularly'the provision of a device of this character which is adapted to grasp an insulated conductor and to removably hold it in place in an insulator into theinterior of which said insulated conductor projects.
More particularly my improved device is adapted for use in connection with the mounting of a high potential insulated conductor within an insulator that is adapted to carry a high potential device such as a gaseous conduction tube which may, for instance,-be of the order of the well known neon advertising My invention in its preferred form contemplates the provision of a device having several indenting elements which are adapted to be indented inthe insulating covering of the conductor. The device has additional means by virtue of which in its preferred form, it may be removably secured to the insulator, preferably by spring or snap action. The device then' also has certain aligning features by virtue of which the parts are held in their proper relationship.
I will describe my invention more in detail by referring to the accompanying drawings in whichv Fig. 1 shows a side view of my improved device mounted in place upon an insulator and holding the conductor in place; and
Fig. 2 is a similar view at right angles thereto. j
In Fig. 1 I show an insulator 10 as adapted to support a gaseous conduction tube 11 and which is adapted to receive its current from an incoming conductor 12. The tube itself has an electrode 13 and the inner connections between the conductor 12 and the electrode 13 are shown and claimed in my co ending application, Serial No. 331,898, filed ganuary 11, 1929. Y
The incoming conductor 12 has a coating of insulation 14. The mouth 15 of the insulator into which the insulated conductor eX- tends is preferably circular in form.
My improved devicey in the form herein shown consists of a body portion 16 which encircles about 180 of the mouth 15 of the insulator. At its free extremity it hasdownwardly projecting arms 17, each provided at their extremities with prongs 18. These prongs are adapted when the device is mounted in place to be indented inthe insulating coating of the insulated conductor and their indenting isu brought'about by sliding a ring 19 over these arms into the` final position shown in Figs. 1 and 2. The arrangement is such that the prongs may move outwardly a trifle after the ring has moved over the protuberant along the'y prongY into theposition f shown, but this retractile action is not sufficient to release the insulated conductor.
The body portion 16A also has an aligning element 2O which projects inwardly and engages the lower 4face of the mouth 15. The body portion 16 also has upwardly 'extending fingers 21 which have inwardly bent portions 22 adapted to project into slots 23 provided in the outervside walls of the mouth 15. These fingers 21`are resilient and per-- mit of the ready and quick attachment and detachment `of my improved device. The structure, however, is sturdily built so that the connection when made is substantial.Y
' It will be seen that many modiiications may be made from this exact structure without depprting from the spirit of my invention.
- aving, however, thus described one form which my invention may take, what I claim as new and desire tosecure by Letters Patent 1s: Y 1.`v A clamp of the character described adapted tosecure an insulated conductor so as to project into a hollow insulator compris-V ing a pair of prong-like elements adapted to be indented in the insulated covering of said conductor, means for uniting said elements, means whereby said elements and uniting means may be attached to said hollow insulator, and a slidable clamp for indenting said prong-like elements in said insulated coverlng.
2. A clamp of the character described adapted to secure an insulate-d conductor so as to project into a hollow insulator comprising a pair of prong-like elements adapted to be indented in the insulated covering of said conductor, means for uniting said elements,
means whereby said elements and uniting means may be attached to said hollow insulator, and a slidable ring for indenting said prong-like elements in said insulated covering.
3. In combination, a hollow insulator, an insulated conductor projecting into said insulator and a clamp for clamping the conduetor in place comprisinga. body portion ,o having spaced projecting resilientprongs for hooking into the insulated covering ot the conductor, and having spring fingers for attachment of the body portion to the insulator, said insulator having means receiving said ,5 fingers to hold them in place. il. In combination, a hollow insulator, an
insulated conductor projecting into said insulator, and a clamp for clamping the conductor in place comprising a body portion m having spaced projecting resilientprongs for hooking into the insulated covering of the conductor, and having spring lingers for attachment of the body portion to the insulator, said insulator having recesses formed there- I, in receiving said lingers to hold them in place.
5. A clamp for connecting a conductor having a Covering of insulating material to a hollow insulator into which said conductor u extends comprising a body portion substan` tially semi-circular in form having at its extremities oppositely directed resilient proj ections, the projections extending in one 'direction having hooks for embedding in the covering ot the conductor and the projections extending in the opposite direction being oset to for holding portions t-o receive the insulator.
6. A clamp for connecting a conductor 4., having a covering of insulating material to a hollow insulator into which said conductor extends comprising a body portion substantially semi-circular in form having at its extremities oppositely directed resilient pro 45 jections, the projections extending in one direction having hooks for embedding in the covering of the conductor and the projections extending in the opposite direction being offset to form holding portions to receive 5a the insulator, -said body portion having a shoulder intermediate its ends forming a stop for aligning the body portion at the end of the insulator.
In witness whereof, I hereunto subscribe nn my name this 18th day ofOctober A. D., 1928.
