TROLLEY.

SPECIFICATION forming part 0f Letters Patent No. 550,059, dated November 19, 1895.

Application filed March 9, 1895. Serial No. 541,139. (No model.)

To all whom, it nubi/concern.'

Be it known that l, FRANCIS J. PRIBYL, a citizen of the United States, and a resident of Hazelton, county of Luzerne, and State of Pennsylvania, have invented certain new and useful Improvements in Trolleys, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts in all the figures.

This invention relates to trolleys for electric street and other railway cars, and has for its object to provide perfectlyoperating means whereby when the trolley accidentally slips from the conductor or wire the same will be automatically and almost immediately returned to the same.

The invention consists in the novel con struction and arrangement of parts whereby the above mentioned and other desirable results are attained, and hereinafter fully described.

Referring to the drawings, Figure l is a rear elevation of a device embodying my invention. Fig. 2 is a side elevationof the same. Fig. Sis a detail sectionupon the line y y, Fig. 1. v

In the practice of myinvention I secure to thetrolley-rod A, appreciably below the top thereof, a forked standard B, having a diagonally-ranging extension or angle-brace a upon the lower end thereof adaptedfto engage the trolley-rod, whereby the standard is supported in the perpendicular position while a trolley is upon the wire, and fastened upon said rod through the agency of an angle-brace a', secured thereto by means of bolts b eX- tending through ilanges a2 upon both braces.

In the arms B' of the fork B, from slightly below the top almost to the bottom thereof, are formed vertical slots c, within which said arms are provided upon the inner edges of said slots with vertical grooves d, in which are slidably inserted vertical bars or plates C, as best indicated in the sectional view, Fig. 3, and shown by dotted lines in the remaining iigures.- The plates C are connected near the center by means of a cross-bar C', secured thereto by means of bolts e, inserted through said plates, and further connected to the same by means of braces C2.

Journaled in the upper ends of the plates C is a shaft l), upon the center of which is looselymounted a peripherally-concaved friction-roller E, at each side of which, between the same and the plates C, are rigidly secured upon theV shaft elongated rollers or drums F, having formed in the periphery thereof spiral grooves f, concaved, and having the direction of each'of the same from the outer edge inwardly to the friction-roller E.

Upon the outer end of the shaft D, which is extended beyond the plates C at one or both sides, is secured a cord G, extending downwardly around a pulley g upon the lower end of the adjacent plate C, the said cord then extending upwardly and having its end secured to a stud h upon the arm B of the fork B. Thev end or ends have annular flanges D- thereon to prevent the cord from slipping off the same. Upon the inner side of the fork, or that nearest to the trolley-rod A, I secure a segmental strip H, having its ends inserted through braces c', secured to the upper ends of the forkby means of bolts t', eX- tending therethrough. The plates C, when in the normal position shown in the drawings, rangeupon a substantial level with the under surface of the trolley-,wheel A, bearing upon the conductor or wire A2, and the segmental strip II in such position projects slightly abovesaid plates. The heightof the device mayfhowever, beadjusted through the agency of the angle-braces a and a and the bolts b.'Y The operation of the device willbe readily understoodl from the foregoing description, taken in connection with the accompanying drawings. When the trolley-'wheel A slips from the conductor yA2, the weight of said wire, and, furthermore, the natural upward tendency of the trolley, will cause the said wire to fall upon the segmental strip H, by which it Will. be immediately guided to the outer end of either of the rollers or drums F to rest in the groove f thereof, and as the momentum of the car will vcarry the same an appreciable distance the friction of the drum with the trolley-wire will cause the same to revolve, and, by reason of the spiral direction and arrangement of the 'groove f, carry the said wire inwardly to the friction-roller E, on which it will rest, while at the same time IOO the revolution of the shaft will wind up the cord G and thereby elevate the plate (l, and through the cross bars and braces c' c2 the opposite plate correspondingly, thus carrying the friction-roller E up to or beyond the level of the trolley-wheel A', and said frictionroller E, being in alignment with said trolleywheel, the wire Afa will be consequently seated thereupon and the car proceed as ordinarily. It is to be noted that as the friction-roller E is loosely mounted upon the shaft, the moment that the wire has been lodged thereon and by the actuation of the shaft raises said roller to seat the wire upon the trolley-wheel, the revolution of the shaft will cease, and the weight of the plates C, the rollers and shafts thereon, and also the intervening cross-bars, will cause the said roller E to descend and the shaft unwind, thereby restoring the whole device toits normal position. The segmental strip II not only guides the trolleywire to the rollers, but furthermore directs the same to the outer edge of the roller, whereby the same is revolved sufficiently to raise the plates C a uniform distance.

In order that the current may be constantly continued through the trolley-rod C, I connect one of the plates C, or other part of the rolleibearings, with the upper end of the trolley-rod by means of a wire or other conductor I, whereby when the trolley-wire A2 falls from the wheel A to the roller E the said trolley-rod will still communicate the current to the motor. I may also mount the forked standard l5 upon the rod Aat the angle indicated by dotted lines in Fig. 2, whereby the raising of the wire will be effected at less distance from the trolley-wheel A.

The advantages resultant from the use of the invention will be manifest to all who are conversant with the general class of devices to which the same appertains.

I do not confine myself to the exact formation of parts or construction of details herein set :forth and illustrated.

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

l. The combination, with a trolley rod of an attachment secured thereto, havin g rollers jou rnaled thereon, adapted to receive the wire and carry the same inwardly to align with the trolley wheel, means whereby the revolution of said rollers elevates the same to the height of the trolley-wheel, and a segmental strip eX- tending normally above the same to direct the wire thereto.

2. A device .for restoring a trolley wire to the wheel,which comprises a stan dard secured to the trolley rod, one or more plates or supports sliding vertically in said stam'lard, a shaft journaled in said sliding plates, rollers mounted upon said shaft at either side, and having spiral grooves therein directed inwardly to carry the wire into alignment with the trolley-wheel, a cord secured to said shaft and to the standard, and extending around a pulley upon the plate orsupport, wherebythe rotation of the shaft elevatessaid plate.

3. A device for restoring a trolley wire to the wheel,which comprises a standard secured to the trolley rod, one or more su pports sliding vertically in saidstandard, a shaft jour nailed therein., a frictioirroller loosely mount-- ed upon the center of the shaft in alignment with the trolley-wheel, rollers secured to said shaft at either side of said friction-roller, hav ing spiral grooves therein directed inwardly to carry the wire to said friction-roller, a cord secured to the end of the shaft and tothe standard, and extendingaround apulley upon the lower end of the support, whereby the rotation. of said shaft elevates the plate, and a segmental strip secured to the standard normally above the rollers, and adapted to direct the wire to the outer ends thereof.

4. A device for restoring a trolley wire to the wheel, which comprises a forked standard detachable and adjustably secured to the trolley rod, plates sliding vertically in each arm of said standard, a shaft journaled between the same, having a friction roller loosely mounted thereon,rollcrs secured to said shaft, having spiral grooves therein directed inwardly to carry the wire to the friction-roller, cross-bars and braces connecting the plates, whereby they work in unison, said plates and the rollers being normally depressed below the level of the t1'olleywheel, a cord secured to one end of the shaft and to the top of the forked standard, and extending around a pulley upon the lower end of the adjacent plate, whereby the rotation of said shaft winds up the cord and elevates the rollers to the level of the trolley-wheel, a segmental strip secured to the standard and extending across the same normally above the rollers, whereby the trolley wire is directed to the outer ends of the same.

In testimony that I claim the foregoing as myinvention I have signed my name, in presence of two witnesses, this 125th day of li`ebruary, 1895.

FRANCIS J. PRIBYL.
