Application filed'M arcli 7,;1904 Serial No. 196,829- (No model.) v

To all whom it may concern:

Be it known that I, CLYDE B. WYNEGAR, a citizen of the United -States',-residing at Greenwood, in the county of-Johnson and State of Indiana, have inventeda new and useful Improvement in Pole Clamps or Couplers, of which the following is a specification.

My invention relates to a pole clamp or coupler, the object being to provide a device;

of this description which will easily and quickly elfect the replacing of old poles with new ones in a more expeditious manner than heretofore. v I

- A further object is the provision of a device of this description which will permit the in:

stantaneous alinement of the pole and trolleywheel carried'thereby with the wire. In this respect I would state that when replacing the usual trolley-pole now in use the proper-alimement is not attained, and as a result the trol- Icy-wheel is set at an angle with the wire, thereby cutting the. side of the wire at all times and grinding it away .until the wire breaks. will climb the wire or runoff, and in such event when the car is running at the usual rate of thirty-five miles an hour on interurban lines the pole will be brought sharply against the cross-arm carrying the wire with such force as to break the pole or at least bend it double and render it unfit for further use.

My device is intendedto preventto a large extent the disengagement of the wheel and wire, and in the event that the wheel does run OE and the pole becomes damaged to provide means for quickly inserting a new pole with no appreciable loss of time. 7 V

In carrying out these objects; my invention consists in certain novel details of construction and arrangement of parts, such as will be more" fully described hereinafter and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation of my improvement applied to a pole, parts being broken away to show the structure more clearly. Fig. 2 is a detail View, in side elevation, of the fastening means for the clamp. Fig 3 is a top plan View of Fig. 1; and Fig. 4: is a view in side Also in making curves the trolley elevation, showing the clamp in its open position.

My invention is intended not only to serve as a clamp, but also as a socket for the pole, .thev shank 3 of the clamp being inserted and bolted fast to the support in place of the usual 1 pole, the collar 4; on the shank abutting the support to limit its inward movement.

At the outer end of the shank is located an outwardly-projecting shoulder 2, from which entends a semicircular or other shaped halfsleeve .1, the upper outer surface of which is provided with a series of corrugations or.

ridges 6 for a purpose hereinafter set forth. The extreme upper end of the half-sleeve may be rounded, as shown.

The shank, collar, shoulder, and half-sleeve areall preferably made in one piece or integral with one another, the upper end of. the shank forming a seat for the end of the pole 14:, and the half-sleeve, which may be semi cylindrical in cross-section, is provided with a stud 5, adapted to be received in a recess or aperture formed in the pole 1 1.

At a point opposite the h lf-sleeve 1 the shoulder 2 is provided with an aperture or ring 9,. adapted to receive the projecting hook 8 of the-movable member? of the clamp, the half-sleeve 1 forming the stationary member of the clamp. This movable member consists of a half-sleeve, forming the. complement of the stationary member 1,-the two members failing to inclose the pole 14, thereby leaving a space between the longitudinal edges of the sleeves to permit the members to clamp tightly on the pole.

The perimeter of the movable member 7 is provided with a stud .10, adapted toproject into a recess or opening formed .in the pole, preferably at .a distance from the aperture wherein lthe stud 5 is received.

Theclamping or fastening means consists of alstrap: 11, preferably-circular in form, as shown; and adapted to embrace the fixed and movable leaves 1 7 respectively, the strap be-' ing'provided at its endswith projecting per- PATENT OFFIC f5 forated ears or lugs 15 15, in which-wperforations is located a pin 16, on which is journaled the cam 12, provided with thelever 13.

wedge.

At a point opposite the cam the ring is provided with teeth 17, adapted totake into and mesh with the teeth or corrugations 6 on the fixed member or leaf 1 to prevent any possibility of the fastening member slipping on the leaves.

The operation of my device can be easily gathered from the foregoing when taken in connection with the drawings; but, to briefly recapitulate, when it is desired to place a pole or replace an old one, the lever 13 is thrown upward, thereby rotating the cam 12 and releasing the pressure of the cam on the movable leaf 7, the ring being disengaged from the teeth 6 and slid upward beyond the leaves to permit the movable leaf to swing downward on the hinge formed by the hook 8 and ring or aperture 9 of the shoulder. The old pole, if there is one in place, is then removed by pulling laterally thereof, a new pole having the necessary apertures formed therein being inserted in a sidewise manner, the end of the pole resting on the seat formed by the upper end of the shank, the stud 5 fitting into its aperture in anew pole. It should be observed that the poles are each provided with the apertures located preferably diametrically opposite one another, and these apertures are bored by placing the pole in a jig for that purpose. It is also to be noted that the socket should be secured to the car in a correct position, so that when the pole is in place the trolley-wheel will aline with the wire. The movable leaf is then returned to its place, its stud 10 received in the pole. The strap, which was threaded onto'the pole prior to its insertion in the socket or clamp, is now slid down over the movable and stationary leaves, the teeth 17 of the strap engaging teeth 6 on the leaf 1, and the lever 13 pushed downward, clamping the pole tightly in position, the movable leaf being pressed tightly against the pole.

It will be noted that the leaves 1 and 7 are tapered from bottom to top, gradually enlarging on their outer faces in the shape of a Furthermore, the outer end of the handle 13 of the lever is curved, so that when it is in its depending position, as shown in Fig. 1, the end of the lever lies against the leaf 7 and is protected by the shoulder 2 against accidental displacement.

It is evident that many changes might be made in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact construction herein set forth; but,

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