Long Beach, in the county of Los Angeles To all whom it may concern Be it known that I, ToMrsoN- P. REED, a citizen of-the United States, and resident of and State of California, have invented certain new and useful Improvements in Railway-Switches, of-which the following is a specification.

p The invention relates to improvements in railway switches of that type which are automatically operated by mechanism on a car. i

The object of the present invention is to equip the track with simple and compara tively inexpensive switch mechanism, and 3 to provide a simple, practical, and efficient q construction, adapted to be readily applied to a car, and which will be under the control of the motorman of a street railway car or the engineer of a locomotive, for

positively operating the switch. J

With these and other objects in view the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from'the spirit or sacrificing any of the advantages'of the invention.

In the drawing: Figure 1 is a plan view of a railway switch constructed in accordance with this invention. Fig. 2 is a plan view of a street car truck equipped with car I pmechanism constructed in accordance with this invention.

Like numeralsof reference designate corresponding parts in all the figures of the drawing.

In the accompanying drawlng, in which i is illustrated the preferred embodiment of the invention, the railway track is equipped with switch rails 8 connected by cross braces 6 and 7 which maintain the switch rails in Specification of Letters Patent. 1 7 Patentedlfielo. 165, Application filed April 17, 1913.

RAILWAY-SWITCH, i l l transverse alinement. The cross brace 7 is provided with a rearextension 9, which is pivoted at 10 to one of the cross ties, and in the operation of the switch, the pointed ends of the switch rails move laterally a limited distance, theswitch rails 8 swinging on the pivot 10, so thatr one or the other of them will contact with one of the main rails 11' and 12. The cross brace 6, which is located near the pointedends of the switch rails, is pivotally connected at 14 midway between the switch rails to one end of a longitude nally disposed track lever 13, which is fulorumed intermediate of its ends at 15 to one of the cross ties. The other (or free end of the lever 13 is provided withan upwardly projecting antifriction roller 16, adapted to beengaged by car mechanism hereinafter described, to'move the switch lever laterally from one side to theother. When the lever 13 is engaged and actuated by the car .mech anism, the switch rails 8 are correspond ingly thrownto one side or totheother.

No claim is made in the'presentapplication tothe constructionof the track device.

The car mechanism comprises in its construction a longitudinally disposed, horizontally swinging switch operating arm 18, secured at its inner or rear end to a plate 19 which is pivoted at 24tto the underside of a cross bar 20 of a car truck 17 The switch operating arm "tapers forwardly, its front end being pointed and the said arm having an enlarged body portion at the pivot 24: of the plate 19. The plate 19, which extends across the truck, is provided in its ends with recesses 19*, receiving projecting stops 20 of the cross bar 20. The stops 20 are adapted to engage the end walls of the recesses 19 to limit the oscillatory movement of the pivoted plate and the switch operating arm 18.

In order to bring the arm of the switch operating arm 18 within the control of the motorman, the pivoted plate 19 is equipped with a substantially lL-shaped arm 21, provided at its inner or rear end 22 with an attaching portion which is secured to a forward extension of the pivoted plate 19. The L-shaped arm 21, Which extends upwardly and forwardly, carries at its outer or front end a toothed rack or segment 23 of the plate 19 and the switch operating arm 18, and meshing with a pinion 26 of a vertical operating shaft 25. The vertical operating shaft 25 is journaled in suitable hearings on the car and it extends through the platform thereof. The pinion 26, which is suitably secured-to'the-lower end-of the shaft 25, is arranged beneath the platform of the car. The upper end of the vertical shaft. 25 is, provided with a crank handle 27, by means of-which theshaft may be turned to rotate the pinion and oscillatethearm 21. Any suitable means may be provided at the crank; for holding the same in such lposition that {the iarm= will; be in parallelism with the Bfl'llSgl1,t1 lld;-12, or: in such other position ,as may; be :necessary; to move the switch nails either togthe "right or -to the left.

:It is obvious that-the car, orptnuck mechanism-may be ,;used- :on: an 4 engine, cab, 'or tender 'ofn-a locomotive,;ingwhich'case the pivotedrplate 2'9 1nay, EL'S'lllUSlZI'Z'LtGd in Figs. 3 and .i-liof :the drawing, be provided with a near; extension 3:0, to which 'is'pivoted a l0ngitudinally disposed arm 'Q'fgft substantially T;-shaped ilever; This iT-shaped @lever, which is provided with rtransversely {disposed arms 34, is rpivoted centrally of the same :aat 32 #150 :the truck, 1 and 1 a connecting r0fd133 may be attaohed-to: either or-both of the f'laterally extending arms-:34. Through the connecting 5 rod 33 i; the a engineer is enabled :to set ;the mechanism to throvv the switch.

.What is claimed. is

1. A yswitch inclu d-ing @car [mechanism comprising a pivoted" transversely disposed plate movable in a horizontal plane and provided in its -ends with recesses, fixed stops extending into the recesses and arranged to "be engaged by the end Walls thereof for jlimiting the pivotal movement ofthe said plate, a switch operating arm carried by and. extending from the plate and operating mechanism connected with the plate for actuating the same.

2. A switch 'zincluding =car mechanism comprising a horizontally movable pivoted plate, :an arm extending from the plate and proviided witha toothedyrack, an operating shaft havinga pinion :meshing with the nack,1and a switch operating, arm extending from and carried by the pivoted'plate.

A switch including car mechanism comprising a 'pivotally mounted horizontally movable switch "actuating arm, a toothed rack connected with the arm, a pinion meshing with'therack, and an operating shaft connected with-the: pinion for swinging-the larm.
