JAJVKES DELANEY, OF COEUR DALENE, IDAHO.

Application filed July 30, 1913;

To all whom it may concern Be it known that 1, Limits DELANEY, a citizen of the United States, residing at Coeur dAlene, in the county of Kootenai and State of Idaho, have invented new and useful Improvements in Electric Conducting Mechanism, of which the following is a specification. q

The present invention relates to improvements in electric conducting mechanism for an over-had source of electricity, the object being to provide a traveling body, such as a car, with means whereby electricity will be conducted from an over-head or feed wire to the motor in the car, the said means being automatically retainedin contact with the feed wire under ordinary conditions or when contacting with an irregularity or obstruction in the. wire, and furthermore, whereby .the frictional contact between the said memher and the wire will be sufiiciently slight as to obviate the liability of injury to the said feed wire or to the said mechanism.

With the objects above set forth in view, and others which will appear as the nature of the invention is more fully understood, the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims.

For the purpose of illustration the accompanying drawings illustrate a satisfactory reduction of my improvement to practice, but the nature of the invention necessarily renders the same susceptible to embodiments in various forms, all of which, however, fall within the scope of the appended claims.

In the drawings: Figure 1 is a side elevation showing the conducting device or trolley in contact with the, feed wire, parts of the improvement being shown in section, Fig. 2 is a similar view but illustrating the trolley in its lower position, and out of contact with the feed wire, Fig. 3 is a trans" verse sectional view on the line 3-3 of Fig. 1, Fig. 4 is a top plan view, Fig. 5 is a central vertical longitudinal sectional view of the device illustrated by Fig. 3. Fig. 6 is a detail perspective view illustrating one of the ends of the upper portion of the conducting member or trolley, and Figs. 7 8, 9 and 10 illustrate details.

Referring now to the drawings in detail, thenumeral 1 designates the top vof an ordinary trolley car or other self-propelled Specification of Letters Patent.

vehicle which is adapted to receive its energy from an over-head electric feed wire 2 which is conducted from the said wire to the motor of the car through the medium of my improvement which is broadly designated by the numeral 3.

The improvement. comprises diametrically oppositelydisposed supports 41: for a shaft 5 which is arranged transversely of the longivtudinal plane of the body of the car. J ournaled upon the shaft 5, and to the opposite ends thereof inward of the supports i are what I term guide members 6. Each of the guides 6compr1ses a substantially rectangular memberwhioh is slotted or bifurcated below its upper end which is trunnioned upon the shaft 5, to provide the said member 6 with spaced arms 7 The arms 7 are adapted to serve as guides for a traveler 8, and each of said travelers may have its sides grooved to insure the same against acciloosely secured to each of the arms"? and which freely pass through the openings in the brackets, the rods being preferably threaded and are provided with adjusting .95 elements, in the nature of flanged nuts 14:

which engage with the free ends of the springs, to adjust the tension of the said springs.

arranged atone end of the car. A weight 19 is arranged within the well and has connected thereto a cable 16. The cable passes over a pulley 18 that is arranged upon the top of the car abovethe well 20. Thecable 16 is provided with a divided end, or in other words, has its free end made up of two strands, each of which being indicated by the character 16.

The numerals 17 indicate grooved wheels, one of which is arranged at the lower corner of each of the guide members 6.

The numeral 20 designates a well which is.

The numerals 18 indicate guide pulleys, one of which is mounted for rotation, upon the top of the car, adjacent each of the guide members 6.

One of the strands 16', of the cable l6,

passes under the guide wheel 17 of the member {3 which is disposed adjacent the well 20. This strand 16 is trained over a sheave wheel 15 which is mounted upon a shaft carried by the traveler 8 arranged upon the rete red to guide member 6, and the end cit said strand 16 is secured to the member 6 opposite the guide wheel 17. The second strand 16 passes around the first guide pulley 18, or the guide pull'ey disposed nearest the well 20, the said strand 16 being then continued longitudinally of the car around the second guide pulley 1S, and from thence passed under the second guide wheel. 1? over the second sheave wheel. 15, which is journaled upon a shaft provided by the second traveler 8, and the said. strand is then continued downwardly and secured to the second guide member 6 opposite its guide wheel 17. The lower portion of the well. 20 is in the nature oi a cylinder and is indicated by the numeral 21, and arranged within the said cylinder is a piston 22-, and the stroke of the piston may be limited by a. suitable outlet port in the cylinder 21, the said piston extending to within the well, but disposed at a. suitable distance below the weight 19. The cylinder 21 may rec 've its power from one of the pipes of the air brake system connected with the car, and the said pipe, which may be desig nated by the numeral 2, is provided with a. valve 24 whereby the air may be forced to within the cylinder to project the piston rod 22, or whereby the air may be prevented from entering use same. The piston. may be provided with the usual spring for retracting the same when the piston head. is not "influenced by the fluid within the cylinder.

Pivotally connected with each of the travelers 8 the end links 95 of a toggle lever system, which is designated broadly by the numeral The links or arms connected. with the end linlrs are preferably centrally enlarged, the said enlargements being formed with openings, whereby the links, which. may be designated by the numerals 27, are journaled upon the shaft 5.- The links of the toggle system above the said links 27 are centrally connected with the links 28, as well with the remaining links of the toggle system through the medium of suitable pins 29, and the pins 29, while sufliciently strong to normally sustain the toggle system in either its extended or collapsed position, are also suliiciently brittle or weal: as to break under an abnormal strain.

The upper pairs of links of each of the toggle systems are pivotally connected between ears 80 provided upon the opposite sides of a substantially rectangular frame 31. This frame 31 comprises a pair of spaced upper or connecting members 32 to which are secured adjacent their lower edges pair of longitudinally extending bars 33, the same projecting a suitable distance from the outer laces of the members 32 and having their ends connected by a spacing bar 3%. The frame is further provided with a central brace member which is connected with the bars 32 and S t and which has its ends arranged at a downward curvature, but its main body disposed directly centrally of the bars Secured to the ends of the bars 3a; and connecting the ends of the central supporting member 35 are curved side supports 36. This structure is adapted to provide a strong and ellicient frame which will effectively support the conducting rollers 37 and 38. lhe rollers 38 are hollow, and are formed of some suitable electric conducting material, such as copper or the like.

The ends 39 of stub axles 40 which are secured to the members 32 through the me dium of retaining elements l1, are inserted in the ends of the rollers providing shafts or trunnions for the said rollers, and if desired, the rollers may contain a filler or core of non-electiic conducting material, in which instance, the core or filler will be secured within the said rollers, and the ends of said cores or fillers will be disposed opposite the ends 39 ot the stub shafts l0, and will serve two purposes; namely, the reinforcement of the roller and their ends being disposed opposite the ends of the stub shafts will prevent or limit alongitudinal movement of the rollers upon the stub shafts.

The rollers 37 and 38 are of a sutlicient cross sectional diameter to at all times project above the central bar 35 of the frame 31, and the conducting wires are attached to the conducting members 4-.0 and lead therefrom to the motor in the car. The direction of travel of the car may be regulated by a suitable switch arranged within the car (not shown).

It is to be understood that the weight 19 is not adapted to force the rollers 37 and violently into contact with the feed wire and also that the toggle lever systems are adapted to permit of the upper frame and its conducting rollers being free to move downwardly away from the wire when an obstruction occurs in the wire, and also that the springs 9 and 10 will permit of the members (3 rotating upon the shaft 5 so that the rollers may readily adjust themselves in proper contacting position with the wires, so that under ordinary circumstances, danger of the breakage of the mechanism is rendered less liable. However,

should the rollers be contacted violently by an obstruction of a greater size or magnitude than that ordinarily experienced by a trolley wheel upon a trolley wire, the pins 29 will break and permit the upper frame 31 and its conducting rollers to drop upon the top of the car without inflicting a serious injury to the device or to the feed wire, and from the above description taken in connection with the drawings, the improvement will, it is thought, be understood and appreciated by all those skilled in the art to which such inventions appertain without further detailed description.

Having thus described the invention, what I claim is:

l. The combination with an overhead feed wire and an electrically propelled car, of an electric conductor arranged upon the car and adapted to contact with the feed wire, said conductor including roller members which are disposed transversely of the wire and which are supported upon a frame, lazy-tongs systems for the ends of the conductor, each supported at one of its intermediate pivots, a traveler connected with each of the lower end links of the lazytongs system, a guide for each traveler, a grooved wheel upon each of the travelers, a weight, a cable connected with the weight, guide wheels, said cable having its free end divided to provide two strands each of which passes over certain of the guide wheels, is trained over the grooved wheel of the corresponding traveler and is connected with the guide member below the said grooved wheel.

2. In combination with, an overhead feed wire and an electrically propelled car, of an electric conductor for the car arranged transversely of the car and adapted to contact with the feed wire, pivoted cross links comprising a lazy-tongs system connected with the conductor, a traveler connected with the lower end links of the lazy-tongs system, a guide lever for the traveler, a shaft for the guide lever, a support for the shaft, a well, a weight within the well, a cable connected with the weight, and said cable having one of its ends connected with the guide wheel and engaging with the traveler to normally force the travelerin one direction upon the guide.

3. In combination with an overhead feed including a balancing weight and coacting,

with the traveler for normally retaining the traveler in one position upon the guide to expand the cross links to bring the conductor into contact with the wire.

4. Incombination with an over-head wire and an electric car, of an electric conductor for engaging the feed wire, cross links having breakable pivots connected with each other and with the conductor, a support upon the car, a shaft upon the support, a slotted guide member connected with the shaft, a follower arranged within the slotted guide member, the end members of the cross links being pivotally connected with the follower, and the cross links being sup ported at one of. their intermediate pivots, a grooved wheel upon the follower, a cable connected with the guide below the grooved wheel and trained over the grooved wheel, a guide wheel upon the guide member below the follower for, the cable, guide rollers for the cable, a well arranged upon the car, a weight within the well, a connection between the weight and the cable, and means for forcing the weight upward of the well to slack the cable to permit of the lowering of the conductor from the feed wire.

In testimony whereof I affix my signature in presence of two witnesses.
