J. BLACKBURN. INSULATOR SUPPORT.

INSULATOR-SUPPORT. I

octave.

To all whom it may concern:

Beit known that I, JASPER BLACKBURN, a

citizen of the United States, and a resident of Kirkwood, St. Louis county, Missouri,

" have invented certain new and useful Improvements in Insulator- Supports, of which the following is a specification containing a full, clear, and exact\ description, reference being had to the accompanying drawings,

forming a part hereof.

My'mvention relates toimprovements in insulator supports, the object of my inven-- t1on being to construct an-adjustable'support which may be readily applied to cross arms of various dimensions, which may be easily shlfted on the cross arms to provide for the spacing of line wires and maybe readily detached without injury to the support or cross arm.

For the above purposes my invention con sists in certain novel features of construction and arrangement of parts as Wlll be hereinafter more fully set forth, pointed out in my claims and illustrated in drawings, in which Figure .1 is a side elevation of the support and nsulator, in position on a cross arm; Fig. 2 is an end elevation of the support and the accompanying insulator in position on a cross arm; Fig.

3 is avertical sectional elevation of the supportand cross arm with a portion of the insulator pin broken away; Fig. 4 is an enlarged detailed sectional elevation illustrating the arrangement of the base of thepin,

whereby a nut is removably positioned in the base of the pin Fig. 5 is a detailed sectional elevation illustrating the arrangement of removable jaw and support base; and, Fig. 6 is a plan of the" modified form of support arranged on the end of a cross arm.

Referring by numeralsto' the accompanying drawings; 1 designates a cross arm of or inary construction, 2 an insulator of the ordinary glass type which is internally threaded and 3 designates the support or pin which is externally threaded at its upper end to be threaded tothe insulator .2. The support or pin is providedwith an integral base 4, preferably made of a greater Specification .of Letters Patent,- I, Patented July 12, 1910, Application filed July 17, 1909. sensitive-{sealer bolt '6.

The base 4 is provided with an angular nut seat 11 and a nut 12 is passed therein to\ coact with the-bolt 6, and, as shown, the core 5 is formed larger than the bolt G'for purposes hereinafter made clear.

In positioning my support on a cross arm, the member comprising the support 3,base 4, jaw 7 and nut 12 is placed at the desired point on a cross arm and the jaw 'is struck with a hammer to seat the teeth 8 in the cross arm, the jaw 9 is then positioned on the cross arm opposite the jaw 7 with its inner upper portion riding over the base 4 and is struck to seat the teeth 10, in the cross arm. The bolt (3 is then inserted through the member 9,

through the right hand end of the core 5 and seated in the nut 12 and brought to a position to secure the aws 7 and 9 against movement relative to each other and the bolt pass ing freely through the right and left hand ends of the core 5 in the base.

It is obvious that by the arrangement of the removable screw seat for the bolt, the bolt and seat may be removed after having been used for some time and corroded or rusted by the element without injury to the support or clamping jaws.

I do not wishto be understood as limiting myself to the use of a removable seat for the,

bolt as .it is obvious that the bolt may be either threaded in the core 5 or extended on through the jaw 7 and threaded in the overhanging wall of the jaw 7. It is obvious further that the aw 7 may b formed separate from the base 4 and the bolt extended through the jaw 9, base 4 and clamping jaw Q' isi arranged for movement seated in the threaded aperture formed in I the overhanging wall of the jaw 7 I I In the modified form, shown in Fig. 6, I have-provided asu'pport especially designed to be employed over the end of a cross arm. When employed in this position the weight of the insulator and wire carried therebv "willexert great strain upon the clamping jaws and to provide for this I have arranged an arm 13, formed integral with the base 4 which projects upwardly along the end, thence along the top of the cross arm and is fastened by nails, screws or the like.

I claim:

. 1. An insulator support comprising a pin,

a base formed at a right angle to and integral with the pin, jaws arranged to embrace a cross arm and engage said base and means for securing the jaws to the cross arm.

2. An insulator support comprising a pin, a base formed integral with the pin,-a aw formed integral with the base, a movable jaw engaging the base and means for clamping the jaws to a cross arm.

3. An insulator support comprising a pin,

means to secure the jaws to the cross arm.

5. In combinationwith a-cross arm an in the support, a jaw sulator support, a base formed integral with formed integral with the base, amovable jaw engaging the base and means for clamping the jaws to the cross arm.

6. An insulator support comprising a base portion adapted to be positioned on a cross able jaw able paw positioned on said base portion, a

50 positioned on said base portion, a v aw carried by sald base portion, an ad ust-' screw-threaded bolt passing through the upper portion of said adjustable jaw and a screw-threaded opening disposed adjacent the base portion for receiving the screwthreaded portion of said bolt;

In testimony whereof, I have'signed my name to this specification, in presence of two 40 subscribing witnesses.

JASPER BLACKBURN.
