ELECTRIC-POLE STAND.

Specification of Letters Patent.

Patented Jan. 24., 1911.

Application filed January 24, 1910. Serial No. 539,806.

To all whom it may concern:

Be it known that I, DAVID A. MARTIN, a citizen of the United States, residing at Republic, county of Ferry, and State of Washin ton, have inv' ,certain new and usefu Im rovement s in Electric-Pole Stands, of whic the following is a specification.

My invention relates to electric pole stands.

The present invention relates to that class of devices which are adapted to receive the lower end of an electric pole to protect it against decay, being specially adapted for use in connection with telegraph, telephone, and other electric conductor poles, and it has for its object the revision of a simple, inexpensive and dura le support of novel construction, having means for supporting the lower end of the pole and for preventing the support and the pole from sinking materially in the ground after setting, and means for readily clamping or securing the pole in the support, as will appear more ully hereinafter.

In the accompanying drawings :--F igure 1 is a vertical elevation showing the stand in position and a pole held thereby; Fig. 2, a p an view of the stand;-Fig. 3, a cross-section on line 3-3 of Fig. 1; and Fig. 4, a detail of the union of the clamp.

The support. 1, which is of galvanized iron, steel, or other suitable material, and tubular in shape, is of a suitable length according to requirements. This support or socket is split for a art of its length, as shown at 2, this effect ing obtained in any desired manner as, for instance, forming the sup ort out of sheet material which is rolled to t e desired shape and the meeting edges for a certain distance welded or riveted, as shown at 3, the object being to have the upper part of the support compressible so that it may be made to firmly grasp the lower end of the pole 4. The lower end of the sup ort has a transverse member 5 on which the ower end of the pole 4.- is adapted to rest and which prevents the pole from sinking below the lower end of the support and the sup ort and pole from appreciably sinking in t e earth. The split upper part of the support is clamped around the pole by a clamp consisting of a rod 6 encirclin the support and whose ends pass through diflferent o enings in a union 7 and are screwthrea ed and provided with nuts 8 and 9, thus afi'ordin a single, simple and convenient device w ich can be positioned as desired by sliding it along the support and tensioned as may be necessary to insure proper clampingl of the split upper end of the support on t e pole.

In using the support with a pole which has been previously set and has decayed, the pole is jacked up, cut oil above the decayed part, the stub removed, and the lower end of the pole inserted in the support, which latter is placed in the hole in the ground, the clamp bein preferably located above the surface of te ground where it can be conveniently adjusted.

While I have described the invention as especially adapted for use in connection with poles carrying electrical conductors, it is obvious that it is susce tible of many other uses, being adapted or holding any post, pole, or upright support, and I do not limit myself to the use of the invention in connection with electrical conductor poles.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

In a support for poles or the like, the combination with a flexible, metallic tubular casing adapted to be permanently'set in the earth and serve as a stand and to directly receive the pole and provided with a split upper part adapted to directly engage the pole, of a clamp independent of and shdable on said split upper part of the support and adapted to be located at any desired osition to cause said split u per part to 0 am the pole to the casing su ect to release an removal of said pole without disturbing the casing.

In testimony whereof, I hereunto afiix my signature in presence of two witnesses.

DAVID A. MARTIN.
