APPLICATION FILED APR-26, 1912.

WILLIAM H. WILLIAMS, OF CAREY, OHIO.

' INSULATOR. 7

Application filed. Apri126,

To all whom it may concern:

Be it known that I, WILLIAM H. WIL- LIAMS, a citizen of the United States,'residing at'Carey, in the county of Wyandot. and State of Ohio, have invented a new and useful Insulator, of which the following is a specification.

This invention relates to insulators, and contemplates the production of an improved insulator designed to hold one or more wires,

' and to hold wires which cross each other at tails within the scope of gether in an eflicient manner by an angle.

This invention also aims to provide an insulator wherein wires that cross each other may be held in planes that are spaced apart in order to preventthe wires which cross each other from coming into accidental contact.

Another object of the present invention is to provide a two-part insulator of this character wherein the parts are duplicates or interchangeable, and of simple and inexpensive construction, as well as being convenient and eflicient in use.

A further object of the present invention is to provide; a device of this character wherein the two parts may be clamped tomeans ofa single screw or securing member, and by the same means the insulator may be secured to a suitable support.

With the foregoing and other objects in view, which will be apparent as the invention is better understood, this invention resides in the novel construction and combination of parts hereinafter set forth and particularly pointed out in the appended claims, reference being had to the accompanying drawings, wherein the invention is illustrated in its preferred embodiment, it being understood that this invention is susceptible of slight alterations or deviations in its dethe appended claims without departing from the spirit of the invention.

In the accompanying drawings, wherein similar reference characters denote corresponding parts,-Figure 1 is a perspective view of the present insulator as in use. Fig. 2 is an elevation thereof. Fig. 3 is. a central section through the insulator. Fig.- 4

is a perspective view of the two parts of the insulator separated.

Referring specifically to the drawings, each part or section of the insulator comprises a jecting from the ridge of the rib at the ends block'5 having a pair of parallel grooves .9 therein and extending throughthereof with their adjacent faces 7 diverging away'from the block and the lugs having grooves grooves 9, the block alsolhaving a central rib 6 betweenthe-lugs 8.

The parts may be constructed of porce- In assembling the} two parts or sections,

10 ,therein at right angles to the 6.5 opening 11 therein extendingthrough the the ribs 6 of the parts are turned at right angles to each other, the ribs being disposed inwardly, and the parts are then' to cause the lugs 8 of moved together so as each part to straddle or stand astride the rib 6 of the other part. part of the insulator are not only adapted to The lugs of eachstraddle the rib of the other part, but are also adapted to bind upon the rib'of the other part so that the lugsand blocks of the opposite 'parts are spaced from each other when the parts are clamped together. This is of advantage for the reason that breakage or injury to and the wires are between the two members. Theribs being tapered and the adjacent faces of the lugs diverging from the blocks, for readily molding or pressing the elements fromplastic material; In-this manner, the grooves 9 of each part will be'made ;to reg.- ister with the grooves 10 of the lugs 8 of the other part, so that the two pairs of registering grooves will be anglesto each other andin different planes. It will therefore follow, that the insulator may clamp two pairs 0f wires which cross the parts iseliminated, not excessively gripped.-

also provides arranged at right each other so that the wires lie in difierent 7 contact of the wires with each other and to I also firmly grip the wires against sliding motion through the insulator. This insulator may .also be employed for holding single wires which cross each other, or may be employed for clamping one, two or three wires, as will be apparent.

The parts of the insulator are clamped together by means of a screw or bolt 12 which is passed through the openings 11 of the parts, the said openings being adapted'to register when the parts arebrought together, and the screw or bolt may then be engaged to a suitable support in order tosecure the insulator to the support and at the same time clamp the parts of the insulator together in order to hold the wires tightly therein.

head of the securing member, so that the securing member may be passed" through.

'the" insulator in either direction.

The two parts of the insulator are identical in construction so that the parts are intel-changeable, the parts being simple and inexpensive in construction. The two parts being interchangeable permit the parts to be readilyassembled, and prevent confusion,

as well as reducing the cost of manufacture of the parts. 1

.Although this insulator is shown and described as designed for holding from one to four wires, it is understood that the parts may be so constructed as to hold more than four wires, by enlarging each of the parts so as to provide more than two grooves 9 in each part, and so as to elongate the rib 6 in order to provide more thantwo grooves 10 for each part. 1 f

It is furtherunderstood, that this device may be altered in its details in other respects than those mentioned, within the scope of the appended claims withoutdeparting from the spirit ofthe invention.

Summing up the description in a concise and concrete statement, the present insula tor consists of two duplicate parts, each part of whichcomprises a rectangular block having a pair of parallel grooves in its in-' ner face and a rib projectingfrom the inner face between and coextensive with the the ribs being adapted to: cooperate and grooves, the sides of the rib being fiat and lying in planes disposed wholly between and spaced from the respective grooves, the rib havinga central notch and a pair of transverse grooves at the sides of and spaced from the notch, the notches-of the two parts permitting the ribs tp interlock at their central points only, so as to provide spaces between the respective corners of the blocks, and the grooves of'the respective blocks of clamp the wires and conductors in various -manners. .T-he corners of the-blocks being The outer ends of the .openlngs 11 are countersunk to receive the spaced apart when-theparts are assembled, permit the wires to be bent from the groove of one rib to the coresponding groove of the other rib, so that a wire may be connected to the insulator from one direction and then directed angularly, it being possible to accommodate two wires or conductors in this fashion. The sides of the ribs'arealso inclined 0r converged from the blocks to the with the first mentioned sides, the sides of the rib being flat and inclined toward each other, the ribhaving a transverse notch midway between its ends forming a pair of accommodated, it

lugs, the sides of the notch being inclined away from each other, s lugs being tap.- ered and having transverse V-shaped corrugated grooves in their ends, said grooves being spaced from the ends of the rib and sides of the notch, the said face of the block having V-shaped grooves midway between, spaced from and parallel with the sides of the rib and the second mentioned sides of the block, and extending to the first mentioned sides of the block, the said rib being disposed wholly between the second mentioned grooves, the first mentioned andsec-' 'ond mentioned grooves being relatively short and long respectively, the second mentioned grooves being corrugated midway between their ends, and the block having a central bolt opening extending to the bottom of the notch; whereby the lugs of each part may straddle the central portion of the rib of the other part, with the first mentioned grooves of each part cotiperating with the central portionsof the second mentioned grooves of the other part, with the bolt openings of the two parts in register,-

and with the corners of the blocks and ends of the ribs spaced apart to form corner pockets.

2. A two part insulator, each part comprising a squarezblock having a rib on one face extending between two opposite sides midway between and parallel with the other sides, the rib havin a transverse notch midway-between its en s forming a pair of lugs,

said lugs having transverse grooves in their ends, the said face of the block having grooves betweenand parallel with the sides of the'ribs and the second mentioned sides I of the block, and extending to the first mentioned sides of the block, the said rib being disposed wholly between the second mentioned grooves, and the block having a central bolt opening extending to the bottom of the notch; whereby thelugs of each part may straddle the central portion of the rib of the other part, with the first mentioned grooves of each partcooperating with the central portions of the second mentioned grooves of the other part, with the bolt openings of the two parts in register, and with the corners of the blocks and ends of the ribs spaced apart to form 'corner pockets.

In testimony that I claim the foregoing as my own, I have hereunto aflixed my' signature in the presence of two witnesses.
