ATTACHMENT FOR ELECTRIC TROLLEYS.

SPECIFICATION forming part of Letters Patent NO. 631,596, dated August 22, 1899. Application filed February Q, 1899. Serial No- 705,063. (No model.)

To all whom it may concern: Be it known that we, HERMAN STUEMPFLE and JOHN DELANE, of Terre Haute, in the county of Vigo and State of Indiana, have invented certain new and useful Improvements in Attachments for Electric Trolleys; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

This invention relates to trolley-wheels and trolley-poles of electric railways, and has for its object to provide an improved attachment, adapted to be secured to the pole, by means of which a sleet-wheel may be attached when necessary or an auxiliary trolley-Wheel brought into use in case of accidental breaking or wearing out of the ordinary trolleywheel or the harp or forked socket in which it is journaled.

With these objects in view the invention consists in the improved construction, arrangement, and combination of parts hereinafter fully described, and afterward specifically pointed out in the appended claims.

In the drawings, Figure 1 is a view in side elevation illustrating a short length of the trolley-wire with a sleet-wheel in contact with it and the usual trolley-wheel and pole, the wheels being partlybroken away and the sleet-wheel being secured by means of an at tachment constructed in accordance with our invention. Fig. 2 is a detail sectional view on the broken line- 2 2 of Fig. 1. Fig. 3 is a similar sectional View on the line 3 3 of Fig. 1. Fig. 4 is a View similar to Fig 1, illustrating my attachment in modified form. Fig. 5 is a detail sectional view on the line 5 5 of Fig. 4, and Fig. 6 is a view of the trolley attachment detached.

Like numerals of reference mark the same parts wherever they occur in the various figures of the drawings.

Referring to the drawings by numerals, 10 indicates the ordinary trolley-pole, 11 the harp or forked socket secured on the end thereof, and 12 the ordinary trolley-Wheel pivoted between the arms of the forked socket.

.13 indicates the trolley-wire, and 14 is a toothed sleet-wheel which when used acts as a substitute for and takes the current off the wire in the same manner as the ordinary trolley-wheel, in addition to breaking up the sleet or ice on the Wire. The sleet-wheel 1 L is mounted in a harp or forked socket 15, similar in form to harp 11, which harp 15 is mountedon the end of a rod 16, which forms the main body of my attachment. This rod 16 is curved outward at 17 to pass around the trolley-wheel 12, is provided with a block 18 on its inner side, with a V-shaped groove in its face, to bear against the stem of the harp 11, and is formed at its inner end of an open-ring shape, as at 19, to permit it to he slippedlaterally upon the trolley-pole 10. The upper inner face of the ring shape 19 is made angular, as at 20, to permit of fitting trolley-poles of some slight variation in size,

and a set-screw 21 adapted to bear against the lower side of the trolley-pole, firmly secures the attachment in position.

The construction of our attachment will be readily understood from the foregoing. When it becomes necessary to use the sleet-wheel, the. attachment may be quickly clamped upon the trolley-wheel, the outward curve 17 of rod 16 closely hugging the trolley-wheel in its groove, forming a rigid brace for the attachment and a contact-surface for the trolleywheel for almost half its circumference.

Our attachment may be provided with an ordinary trolley-wheel instead of the sleet-wheel, and one of them may be carried on each car for use in case the ordinary trolley gets stuck and fails to rotate or of any accident which renders the use of a temporary trolley-wheel a necessity.

In Figs. 4 and 5 we have illustrated a modified construction, in which 10 is the trolleypole, 22 a harp or forked socket, and 23 either a plain trolley-wheel or a sleet-wheel. The stem 24 of the forked socket is shaped at its end similarly to the inner end of the bar 16 and has a set-screw 25 to clamp the trolley-pole. In the use of this modification each car is supposed to carry an extra Wheel in a forked socket thus constructed. In ordinary weather the extra outfit will be provided with a plain trolley-wheel and in sleety weather with a sleet-wheel. Should the ordinary trolley wheel 'or its harp or socket become broken or otherwise disabled, it can be at once taken off and an extra one substituted, the extra outfit with sleet-wheel being substituted when necessary.

\Vhile we have illustrated and described eflicient means for carrying out our invention, we wish it to be understood that we do not limit ourselves to the exact forms and constructions shown, as many slight changes and variations therefrom might suggest themselves to the ordinary mechanic which would be clearly included in the limit and scope of our invention.

Having thus fully described our invention, what we claim to be new, and desire to secure by Letters Patent of the United States, is-

1. An attachment for trolleys comprising a harp or forked socket provided at its inner end with an angular clamp open at one side, a set-screw through the side thereof, and a substitute wheel journaled in the arm end of the socket, all substantially as described.

2. An attachment for trolleys comprising a bar curved laterally to fit in the groove of the ordinary trolley-wheel and carrying a clamp at its inner end to secure it to the pole, and a substitute wheel at its outer end, substantially as described.

3. An attachment for trolleys comprising a bar provided at its inner end with means whereby it may be slipped sidewise upon the pole and clamped thereon, and with a substitute wheel at its outer end, substantially as described.

at. A11 attachment for trolleys comprising a bar adapted to be slipped laterally upon the pole, a clamp to hold it thereon and a substitute wheel at its inner end, the bar, intermediate of its ends being curved outward to snugly hug in the groove of the trolley-wheel, substantially as described.

5. The herein-described trolley attachment consisting of the bar 16 curved outwardly at 17 to snugly fit in the groove of the trolleywheel, the inner end of said bar being constructed to form an open-sided ring, angular in section, the set-screw threaded through the bottom of said ring and adapted to bear against the lower side of the trolley-pole, the V-shaped block on the inside of bar 16 to bear against the stem of the harp or socket of the trolley-wheel, and the sleet-wheel j ournaled in a harp or socket secured to the outer end of the bar 16, all substantially as and for the purposes set forth.

6. As an article of manufacture an attachment for trolley-poles curved laterally near its middle portion to fit a trolley-wheel and having a stem on its outer end to fit a socket, an elongated open-ring portion on its inner end having a set-screw to form a grip and an intermediate V-shaped bearing-block in line with the bore of the ring whereby the attachment is prevented from twisting and kept in line on the trolley-pole, substantially as described.

In testimony that we claim the foregoing as our own we affix our signatures in presence of two witnesses.
