EMERGENCY-SHOE.

Specification of Letters Patent.

Patented Sept. 28, 1915.

Application filed November 27, 1914. Serial No. 874,246.

To all whom it may concern Be it known that I, FERNAND E. RIVIERE,

a citizen of the United States, residing at tween the periphery of the wheel and the track; and another object of the invention is to improve the construction of the shoe.

The invention aims to improve generally and to enhance the utility of devices of that type to which the present invention appertams.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made withi in the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawing: Figure 1 is a view partly in section and partly in elevation showing a railroad car equipped with the brake mechanism forming the subject matter of this application; Fig. 2 is a top plan of the brake mechanism; Fig. 3 is a side elevation of the shoe; Fig. 4 is an elevation showing one edge of the shoe; Fig. 5

is a top plan of the shoe; Fig. 6 is a pertail illustrating one of the guides or hangers in which the shoe actuating plunger is mounted; Fig. 9 is a fragmental side elevation showing the position of the shoe and adjacent parts when the shoe coacts with the wheel.

In the drawings, the numeral 1 indicates generally a vehicleof any desired type, such as a trolley or railroad car.

The wheels of the car 1 are denoted by the numeral 2 and the rim of the wheel is indicated bythe reference character 43.

- The track which is traversed by the wheels of the car is shown at 3.

The numeral 4 indicates the truck frame and carries axles 5 upon which the wheels 2 are immediately mounted.

The platform of the car is shown at 6.

Mounted upon some accessible portion of the car, as in the platform 6, is a base plate 7 equipped with an upstanding ear 8 carrying a pivot element 9 upon which is fulcrumed .a lever 10 extended downwardly through the platform 6, the lever 10 being provided with suitable latch mechanism of any desired sort indicated at 11 and adapted to coact with a segment 12 which if desired may be fixed to the base plate 7. Secured to the lower end of the lever 10 and to the car is a retractile spring which serves toprevent too abrupt a throwingof the lever 10 and also aids in returning the parts to the positions shown in Fig. 1.

Pivotally connected with the lower end of the lever 10 as shown at 14 is a rearwar'dly extended pitman 15, mounted to reciprocate in a guide 16 carried by the platform 6. The rear end of the pitman15 is upwardly inclined to form an arm 17 pivotally connected as shown at 17 with an upstanding crank arm 18 on a shaft 19 journaled for rotation in bearings 20 carried by any accessible portion of the frame of the car 1. Projecting downwardly from the shaft 19 is an arm 21 to which is pivoted as shown at 21, a downwardly and rearwardly extended plunger 22. The plunger 22 at its rear end is formed into a goose neck 24 received within a guide 28 depending from the truck frame 4. When the parts are not in operation, as shown in Fig. 1, the goose neck 24 rests upon the lower portion of a loopshaped head 51 constituting a part of the guide 23. The plunger 22 is mounted to move vertically in the loop-shaped head 51 of the guide 23 but cannot rotate or move laterally, as Fig. 8 will make evident. The goose neck 24 terminates in a curved finger 52 and to the goose neck are pivoted links 53.

The invention includes a shoe 25 provided near its upper end with an opening 26 receivlng a pivot element 27 which 1s connected to the links 53. In the shoe 25 at its upper end is formed anopening 28 adapted to receive the lower end of a chain 29 constituting a part of a longitudinally entensible, resilient connection. The upper end of the chain 29 is assembled with the bend of a U-shaped link 30 provided at its upper end with hooks 31. A compression spring'32 surrounds the U-shaped link 36 and the upper-end of the spring 32 is engaged by the hooks 31. The lower end of the spring 32 is engaged by a cross pin 33 mounted in an eye 34 formed at the lower end of a link 35, the upper end of which is connected with a chain 36, the upper end of the'chain 36 being connected as shown at 37 with the truck frame 4. 1

Theforward edge face of the shoe 25 is convexed as shown at 38 and the rear edge face of the shoe 25 is concaved as shown at 39 to conformproperly to the periphery of the wheel 2. The

faces

38 and 39 cooperate to define an entering point 40 which, when the device'is operated, is adapted to move between the periphery of the wheel'2 and the track- 3. The forward edge face of the shoe 25 is a friction face, and with this end in .view, the said face may be grooved or ribbed transversely as shown at 41. The rear, concaved edge 39 of the shoe which coacts with the periphery of the wheel 2 is grooved longitudinally as shown at 42 so as to receive the rim 43 of the wheel 2. EX-

tended outwardly from the friction face of the shoe 25 is a rib 44 whichis adapted to engage the inner edge of the track 3'when' the device is in operation, and owing to the coiiperation betweenthe rib and the track 3 upon the one hand and between the groove 42 and the rim 43 of the wheel 2 upon the other hand, a movement of the shoe in a lateral or transverse direction is avoided.

l/Vhen the structureis not in use, as shown in Fig. 1, the shoe 25 is retracted-from the periphery of thewheel 2. The goose neck 24 of the plunger'22 is supported upon the lower portion of the head 51 of the guide 23,

and thus the shoe 25 is upheld, the lower.

chain 29 of the longitudinally extensible connection hanging slack.

In order to operate the structure, the pit; man15 is actuated through themedium of.

track. The longitudinally extensible 0011- the shoe and supports the shoe in position.

When the shoe 25 enters between the wheel. 2 and the rail 3, the shoe is tilted, and'when the shoe is thustilted, the goose neck 24 in the plunger 22receives the upper end of the shoe andprevents the plunger 22 from being strained by direct contact between the upper end of the shoe-and the plunger. The shoe 25 may be-ra-ised into the position shown in Fig. 1 by a proper manipulation attendant parts being facilitated by the action of the spring 32 and'the .spring 50.

of the lever 10, the raisingof the shoe. and

Having thus described the invention, what I is claimed is 1. In a device of the class described, a wheel mounted vehicle; a fixed, depending guide thereon; an inclined plunger mounted to move longitudinally through the guide in direct contact therewith; awheel engaging shoe pivoted to the plunger; and means for advancing the plunger to lower the shoe; the plunger being provided with means ene gaging the shoe to preventa movementof the shoe in one direction with respect to the plunger, thereby to hold the shoe against tilting with respect to the wheel, when the shoe is elevated.

2. In a device of the class described, a]

wheel mounted. vehicle; a plunger carried thereby; means for actuating the plunger; I

and a wheeland' track-engaging shoe pivotally assembled with the plunger the plunger being provided with a goose neck adapted to receive the upper end of the shoe.

3. In a device of the class described, a

Wheel mounted vehicle; a guide vcarried thereby; a plunger mounted to move in the guide and including a goose neck engaging the guide to support the plunger; means for actuating the plunger to move the goose neck off the guide; and a wheel and track engaging shoe pivotally assembled With the plunger, the goose neck being adapted to receive the upper end of the shoe. 1

4. In a device of the classdescribed, a wheel mounted vehicle; a plunger carried thereby; and a wheel and track-engaging shoe pivotally assembledwith the plunger, the plunger comprising a goose neck adapted to receive the upper end of theshoe' when the shoe, is tilted, and comprising afinger engaging the shoe to support the shoe when the shoe is elevated; and means for actu' ating the plunger.

5. Ina device. of the class described, a."

guide; means for actuating the plunger; and a track-engaging shoe assembled With the plunger; the plunger comprising a goose neck adapted to rest upon the guide to uphold the shoe, and comprising a finger engaging the shoe to limit the tilting movement of the shoe in one direction, the goose neck being adapted to ride off the guide and being adapted to receive the upper end of the shoe When the shoe is tilted out of en- 10 gagement with the finger.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two Witnesses.
