SWITCH,

SPECIFICATION forming part of Letters Patent No. 568,727, dated October 6, 1896.

Application filed M11011 30, 1896.

T all whont it may concern:

Be it known that I, EMIL BALZER, a citizen of the United States, residing in Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Switches, of which the following is a specification.

My invention relates to switches; and it consists of a device for setting a switch and for an attachment on street-cars operating the switch from the platform of the car.

My invention is illustrated in the accompanying drawings, wherein--- Y Figure 1 is a plan of the road-bed, showing the arrangement of a switch and of the contrivance for setting the same, a part of the road-bed being removed to show the arrangements of levers moving the switch. Fig. 2 is a section of a portion of a street-car and of the road-bed, showing my improved car attachment for operating the switch in moment of action. Fig. 3 is a cross-section of the road-bed on the line 3 3 indicated in Fig.

' 1. Fig. 4c is an enlarged sideview, partly a section of the head of the switching-lever. Fig. 5 is an end view thereof. Fig. 6 is a similar view as Fig. 2, only showing the car attachment in position of rest. view of the lever for operating the switching attachment from the platform of the car. Fig. 8 is a front view, partly a section of the post, showing the lever and connection for operating the car attachment by a treadle. Fig. 9 is a top view of the lifting-lever.

Similar letters of reference indicate corresponding parts in all views.

My improved streetcar-switching device consists of two principal parts-of the car attachment and of the contrivance set in the road-bed. The car attachment is provided in duplicate on each end of the car for throwing the switch in either direction and is c011- structed and operated as follows:

Bell-crank lever b is fulcrumed on pivot pa in platform A of the car, and its downward-pointing end, terminating in an elongated eye bs, is connected by pin pb to the switch-operating lever c and to the connecting-rod cl. Rod 0 is balanced on pin 01), so that when in position of rest, as shown in Fig. 6, its tail end, between cp and. pb, will outweight the other part, and vice versa, when Fig. 7 is a side Serial No. 585,369. (No model.)

pushed in position shown Y in Fig. 2', its hooked end f then engaging the head of the sWitch-throwin g bar in the slot of the roadbed. This hooked end f is provided with a roller fr, projecting below its gripping-point and carrying it over the ground. Roller sr, revolving on a pivot, is set in the side of the rod in such a position that it will travel over the block 1'19 on the road-bed as the car moves along and lift up the hooked end of rod 0 from the slot we when the switch has been thrown. Pin cp, supporting lever c in slot cs, is set in bracket at, screwed to the bottom of the car. To this bracket 00 is also pivoted the bell-crank lever 6, whose upper arm is connected by the rod 01 to the bell-crank lever 1). The other arm of lever e is connected directly to lever c, cross-pin ep engaging in the slot es of the lever.

The levers b and e cooperate in their action on the lever c, shifting on pin op. When the same is shifted from position of rest into the operating position, lever 12 moves it horizontally and at the same time lever e, actuated by rod cl, will press its head end downward. When lever c is lifted from the slot by cooperation of roller 89 and block 1'19, then lever 6 will be pushed upward and, transmitting the motion through rod cl, will shift lever c on pin op back in its normal position of rest.

Crank-lever l) is operated from the platform of the car in the following manner: To the standard U, set on the platform adjoining the dashboard, is screwed bracket 11., and to it is pivoted the hand-lever Z. Rod 1' connects the lever Z to the bell-crank lever 11. To the outside of this hand-lever Z is pivoted the releasing-lever rl, so that the two handles of the levers l and rl may be operated with one hand. Pin 19, screwed in the other end of this lever rl and passing through the hand-lever l in the hole It in the post U, holds it in the position shown in Fig. 7. Spring 3, placed between the grip ends of the levers Z and rl, keeps them apart and presses pin 1) into the recess h of the post U.

It is often necessary for the driver of a car to use both his hands in handling the other apparatusniotor, brakeand to enable him to set the switching attachment in such case by foot I have appended to the described apparatus the following device:

ICO

To the post U is pivoted, below the leverl and at right angles thereto, the bell-crank lever bl, whose longer upper arm is forked, the tines thereof passing 011 both sides of the pin p between the hand-lever l and the re leasing-lever rl. The shorter lower arm of this lever 121 is connected to treadle t' by rod ht. Thus when the driver of the car steps 011 treadle t the forked arm of lever DZ will act against pin 1) and move it out of the hole h in the post U, and thus release lever Z from its locked position. Then treadle t, pressed farther downward, will act on lever I) and shift the switching-lever c in act-in g position,

as described above.

The other part of my invention consists of the device for setting the switch arranged in the road-bed. Between the rails, underneath the switch, is laid the base-plate G, wherein the connecting-bar o and the bellcrank levers 7t and n are set. Switch ends St and St are connected to bar 0. Crankdevers M and n have each one arm connected to the bar 0 and the other by means of the springs Sit to push rods K, having shoulders 7r, sliding in slots m, provided in the covenplate M. Against these shoulders K engages the hooked end f of the switching-lever. On the outer sides of these slots m, close to the end of the slit, are set-blocks ip, on which the side roller er of the rod 0 travels, lifting the hooked end f of the switching-lever out of contact with the head k, as described above, after the switch has been thrown. According to what direction the car is to go the switch is set by moving one of the rods K. \Vhen the switch is set so that a car will go straight ahead, as shown in Fig. 1, and is to be switched to the sidetrack, the driver will set the left-hand switchlever in action, and by moving the corresponding rod K shift the switch-tongue St, and the car will take the sidetrack.

I claim as my invention and desire to secure by Letters Patent 1. Aswitchattachmentforstreet-cars, comprising two bell-crank levers, one pivoted in the platform of the car and the other 011 a bracket underneath the car, a connectingrod connecting these bell-crank levers, a slotted oscillating lever, having a changeable fnlcrum, connected to the bell-crank levers, and adapted 'to be moved forward and dowmvard by the bell-crank lever, pivoted in the plat form of the car, and returned to its normal position by the other bell-crank lever; a lifting-lever hinged to a post on the platform of the car, a connecting'rod, connecting the lifting-lever to the bell-crank lever, pivoted in the platform of the car, means for securing the lifting-lever to the post on the platform in position, and means for disengaging the lifting-lever from the post by a treadle, attached to the bell-crank lever pivoted in the platform.
