DIRECT AND MESNE ASSIGNMENTS, OF SEVEN-TENTHS TO ALEXAN- DER S. PATON, OF LEOMINSTER, MASSACHUSETTS.

TROLLEY-SWITCHQ SPECIFICATION forming part of Letters Patent N 0. 668,296, dated February 19, 1901. Application filed November 16, 1899. Renewed December 13 1900. Serial No. 39,767. (No model.)

To all whom it may concern:

Be it known that I, EUGENE J. PARKER, a citizen of the United States, residing at Worcester, in the county of \Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Trolley- Switches; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to overhead-trolley switches; and the object is to improve the construction and increase the efficiency and provide a safe and effective deviceof this character.

To this end the invention consists in the construction, combination, and arrangement of the same, as will be hereinafter more fully described, and particularly pointed out in the claim.

In the accompanying drawings the same reference characters indicate the same parts of the device.

Figure 1 is a perspective view of my improved overhead-trolley switch. Fig. 2 is a similar View with the cap-plateremoved. Fig. 3 is a similar view taken from beneath looking upward. Fig. 4 is a transverse section.

1 denotes the switch-plate, which is of cast metal and formed with lateral ears 2 2, by means of which it is supported in position.

3 denotes the upwardly-flaring front end of the switch-plate, which is formed with a longitudinal groove I to receive the conductorwire 5 and which is alined with a groove 6 in the raised seat 7. This groove 6 forms a continuation of the main-line groove 8 and the branch-line groove 9, in which the conductorwires 10 and 11 are secured by means of the cap-plate 12, fixed in place by the screws 13 13.

The rear end of the switch-plate is bifurcated, as shown, and it consists of the diverging arms 14 and 15, the outer ends of which flare upwardly and are formed with the grooves 16 and 17, which are alined with the seat-grooves 6 and 9 to receive the conductors 18 and 19.

The lower face of the switch-plate is formed with a continuous groove 20 and a branch groove 21, which lies in a lower plane than the continuous groove 20, so that a shoulder 22 is formed at the intersecting point of the two grooves, which forms a guide-wall at this point for the trolley. Both of the grooves are provided with parallel flanges, as shown, thereby providing a safe and certain way of conducting the trolley-wheel into and out of a switch without the liability of having the trolley-wheel jump out, as it is protected the entire length of the switch-plate by the parallel guard-flanges.

The accompanying drawings show my invention in the best form now known to me; but many changes in the details might be made within the skill of a good mechanic without departing from the spirit of my invention as set forth in the claim at the end of this specification.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, 1s-

A trolley-switch, comprising the plate, 1, formed with a flaring front end and a flaring bifurcated rear end which are grooved to receive the trolley-wires and having a raised seat formed with a Y- groove and a correspondingly-grooved cap-plate and having its bottom face formed with a continuous trolleygroove and a branch groove formed in a different plane, substantially as shown and described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

EUGENE J. PARKER.
