SWITCH-MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 541,954, dated July 2, 1895. Application tiled Aprill, 1895. Serial No. 544,095. (No model.)

To all whom it may concern:

Be it known that I, JOHN R. TRIsLER, a citizen of the United States, and a resident of Westwood, Hamilton county, State of Ohio, have invented a new and useful Switch-Movement; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, attention being called to the accompanying drawings, with the referencenumerals marked thereon, which form a part of this specification.

This invention relates to a device or movement whereby railway switches, particularly those of streetrailways may be operated from the car while the latter is in motion. 1

The device consists substantially of three parts, one part being attached to the car and operated therefrom for the purpose of setting the switch. The next part is located below the street surface but accessible to the part connected to the car from which it is operated. The last part finally is that one whereby the second part is connected to the switch and transmits to it the' effects caused by the operation of the part on the car.

The novelty resides more particularly in the construction of the second part, which is the one acted upon by the device on the car, while the other parts contain however also novel features of construction which will become apparent in the following specification and claims which contain a full description of my invention together with its operation, parts, and construction, which latter is also illustrated in the accompanying drawings, in which Figure 1 is a sectional side elevation of all parts of the device, showing also the parts connected to the car in ready position to set the switch. Fig. 2 is a vertical cross-section on line 2 2 of Fig. 1. Fig. 3 is a horizontal section on line 3 3 of Fig. 2. Fig. 4 shows a portion of a railway-track with a switch and a device for operating it, the invisible part of the latter being shown in dotted lines. Fig.

5 is part of a view similar to Fig. 2, showing a modified construction. l

6 is the switch of well known form, pivoted at 7 and connected at its underside near the frontend thereof by means of link 8 to .an arm 9 at the end of a rocking-rod 10. This rod which is supported in suitable bearings, carries at its other end a similar arm 11 which connects to an arm 12 of a short rocking-rod 13, supported in a box 14.. The connection between these armsll and 12 is preferably adjustable, so thatthe amount ot' movement of arm 9 and with it the throw of the switch, may be properly regulated. vRod 13 is connected to a lever 15 which at each end carries loosely connected a pawl 16, which rest normally against a rack 17, adjustably supported at its lower end in a box 18 and near its upper end in a bearing 19. The toothed end 2O ot` one branch of an angle-lever 2l, pivotally supported at 22, engages with this rack, While its other branch 23, provided with a hooked end 24, passes upwardly through a slot 25 and extends above the surfaceof the street. Aweight 26 at the rear end of the angle-lever holds the same normally ina position which brings branch 28 to one extreme end of slot 25 with the toothed branch 2O raised Vto its highest position. Inasmuch as this branch is in engagement with rack 17, the latter will also be held in a raised position. If this branch 23 is moved within slot 25 in the direction of the arrow, rack 17 will be depressed and carry with it by means of one of the laterally projecting teeth 27, the elevated one of pawls 16. See Fig. 2. The depression of this latter by reason of its connection to lever l5, partly rotates or rocks rod 13, which by means of arms 12 and 1l rocks also rod 10, the arm 9 of which, through the intervention of link 8, operates the switch, as will be readily understood. Upon release of branch 23 of the angle-lever, a weight 26 carries it back to its normal position raising also rack 17 again to bring it in ready position for the next operation. No other parts participate iu this latter movement of angle-lever and rack, all retaining their respective positions, the elevated o ne of pawls 16 simply dropping into place under one of the `teeth 27 as soon as the rack has reached the end of its upward movement. On its next depression then rack 17 acts immediately upon the elevated pawl and operates the switch mechanism. During this movement of the pawls in opposite directions,

IOO

it becomes necessary that the rising one clear its tooth 27 which moves toward it with the descending rack. This is done by swinging dogs 28, pivoted at 29 and held to a normal position by weights 30, resting upon brackets 3l, which limit their movement in one direction. The pawls have pins 32 which may carry friction rollers and on the rising pawl this pin passes under the dog 28 above itand is drawn away thereby from rack 17 th us clearing the descending tooth 27. After having passed up on dog 28 and cleared the upper end of the same, the rising pawl drops again over against the rack, tooth 27 having meanwhile passed down. When the rack rises the raised pawl simply slips over the tooth thereon. The descending pawl when its pin 32 reaches dog` 2S, pushes the same simply aside,

' the latter readily yielding and dropping again to its normal position as soon as pin 32 has cleared its lower end. Seeintermediate position shown in dotted lines in Fig. 2. Member 23 of angle-lever 2l is in two parts, one telescoping within the other with a spring 33 between them, whereby that part which pro- -jects above the street-surface readily yields in case any heavy wagonsk pass over it and whereby any strain and damage on the device are prevented. Link 8 is alsoin two parts connected by means of spring 3 4,contained in a teleseoping housing 35 which holds said link rigidly to a straight line and prevents it from collapsing when under stress of thrust. This spring is of such strength that it will not yield during the ordinary operation of the device, link 8 acting then to all practical purposes like a rigid member. In case of any obstructions however interfering with the full movement of the switch, it yields and permits the other parts of the device to complete their full movement,thereby preventing any damage to them. At the upper end of rack'17 is a hood 36, projecting over the toothed end ot' the angle-lever and preventing any dirt entering through slot 25, from dropping between the engaging teeth of lever and rack.

As a modification, the short rocking-rod 13, its box 14 and arm 11, may be omitted and lever 15 in one piece with arm 12 in form of an angle-lever, may directly connect to rocking-rod 10 as shown in Fig. 5. This latter is preferably incased in a pipe or tube 37, while the other parts are 'contained in a suitable casing 23S-which on top is preferably provided with a covered hand-hole 39, through which from time to time accumulating dirt entered through slot 25 may be removed.

For the purpose of operating the switch from a passing car any device capable of engaging temporarily with and then disengaging itself from the upper end of the member 23 of the angle-lever may be used. I prefer a loop 40 of sufficient width which readily engages hook 24 and before and after such engagement freely slides over the street-surface, without defacing the same. It is pivotally suspended from the under side 41 of the car and movably held up by a spring 42. At the proper time the driver or motorman on the advancing car depresses it by means of a link or push-rod 43 with a treadle at its upper end, whereupon it engages the hooked end 24 ot' the angle-lever and takes it along until the switch is properly set, by which time hook 24 has assumed such a position that loop 40 cannot hold it any longer and disengaging itself therefrom,permits weight 26 to carry the hook back again to its normal position. If the switch was in proper position no operation is of course required. The device is located between the rails and connection is made by link 8 to whatever side may be required, to reach the switch, so that it does not matter whether the latter is on the right or left side of the track.

Having described my invention, I claim as new- 1.
