INSULATOR FOR TELEGRAPH-WIRES.
SPECIFICATION forming part of Letters Patent No. 759,276, dated May 10, 1904. Application filed Lpril 10, 1908- Serial No. 151,969. (No model.)
To (ZZZ whom it may concern:
Be it known that I, CLAYTON HOBERT, a citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Insulators for Telegraph-Wires, of which the following is a specification.
My invention relates to an improved insulating device for telegraph-wires, the main object being to facilitate the satisfactory fastening of the wires thereto, while at the same time providing a simple and economical device adapted to the varying conditions commonly met with.
The invention is fully described in connection with the accompanying drawings, and the novel features are specifically pointed out in the claims.
Figure 1 is a central longitudinal section showing a preferred form of my device applied to a supporting-peg. Fig. 2 is abottom view of the cap-section. Fig. 3 is an outer face view of the sleeve-section. Fig. 4 is a sectional view taken on the line 4 at of Figs. 1 and 3. Fig. 5 is an enlarged view showing a wire clamped between the sections, one half of said view showing both sections in full elevation and the other half showing the cap in central cross-section, as in Fig. 1.
A represents a supporting-peg upon which are mounted the sections B and C of my improved insulator. The main insulator-section B, as shown, is in the form of a sleeve, the bore of which is screw-threaded to engage the screw-threaded portion of the peg A, to which it is thus adjustably secured. The cap-section C also screws upon the peg A, being provided with a screw-threaded recess d, adapted to engage the end portion of the peg which projects beyond the sleeve-section B, and it is formed, as indicated, with a projecting circular flange or collar 0 on its meeting face f, adapted to inclose the outer end g of the sleeve section B when screwed down upon the latter, thereby covering the junction between the sections, as well as serving to clamp the interposed wire, as hereinafter described. This outer end 9 of the sleeve-section is provided with one or more wire-receiving slots h extending across its annular face to one side of the inserted peg A, so as to permit the passing of a wire inserted in said slot clear of the peg. I preferably provide a series of these slots of differing sizes to suit various sizes of wire and all lying outside the plane of the peg A, as shown in Fig. 3. The depth of each slot is increased, as shown, toward either end thereof, thus forming a central ridge c' of slightly less depth than the intended thickness of wire, while the depth at either end is increased by about the depth of the collar 6 on the cap-section C. This construction provides for engaging each interposed wire at three points in clamping the same between the meeting faces of the sections B and C, the edge of the collar e pressing the wire down into the deepened end portions of the slots, and thereby forming a kink in the wire as the cap is drawn down upon the sleeve.
The sleeve B may be turned upon the peg, so as to present the proper slot for the particular wire to be secured thereto. The screwing down of the cap upon the inserted wire effectually clamps the latter to the sleeve-section and at the same time so covers and pro; tects the wire as to prevent the admission of rain or sleet between the sections, the junction of which is entirely closed by the depending flange or collar 0. The connection is equally simple and satisfactory for an end tie, the end of the wire being in such case returned through a parallel slot on the opposite side of the peg. The construction may of course be readily modified in detail without departing from my invention.
What I claim is 1. The herein-described insulator, comprising a supporting peg or pin and a relatively adjustable sleeve and cap, said sleeve and cap being disconnected from each other and both mounted on said supporting peg or pin, said sleeve having a wire-receiving groove the ends of which are of greater depth than the intermediate portion thereof and said intermediate portion of less depth than thewire, and said cap having a lower face which bears upon the projecting portion of the wire in said intermediate part and clamps the same at said pl ace, and also having a circumferential flange extending below the plane of the upper surface of said sleeve and inclosing the same, said flange engaging the wire contiguous to the deeper end portions of said groove and kinking and clamping the same at said place.
2. The herein-described insulator, comprising a threaded supporting peg or pin a sleeve having an opening extending through it, said opening having threaded walls to engage said pin and said sleeve having its upper surface formed with a wire-receiving groove which extends across it and is inclined continuously in opposite directions outward and downward from a place contiguous to the center of the diameter of the sleeve to the ends thereof, whereby said groove is shallower at its center than at its ends, the shallower portion of said groove being of less depth than the wire adapted to it; and a cap threaded upon said pin above the top of said sleeve, said cap having a depending circumferential flange which extends below the upper surface of said sleeve and is disconnected from the same and bears upon and kinks the wire adjacent to the deepest part of said groove, said cap also having its under surface arranged to bear upon the part of the wire in the intermediate shallower parts of said groove and serving thereby to clamp said part upon the sleeve.
In testimony whereof I aflix my signature in the presence of two witnesses.
CLAYTON I-IOBERT.
