LIFE-GUARD FOB RAILWAY-CARS.

To all whom it may concern:

Be it known that I, GEORGE A. PARMECN- TER, citizen of the United States, residing at Cambridge, Massachusetts, have invented certain new and useful Improvements in Life-Guards for Railway-Cars, of which the following is a specification.

My present invention relates to improvements in fenders or life guards for street railway cars of the type known as trip and drop scoop, and particularly to those in which the pick up scoop or basket is carried by the truck while the trip frame or gate is carried by the car body. Such type of wheel guard is particularly advantageous in connection with the double truck or swinging bogie cars which are now coming almost exclusively into use.

The invention has among others for its objects to simplify the construction, to reduce the cost, to enable it to be more easily applied to the cars, to make it easy and certain in action, and of advantage in other respects as will hereinafter more fully appear.

The invention includes the novel features of construction and arrangement and combination of parts hereinafter described and particularly set forth in the appended claims.

An embodiment of my invention is illus trated in the accompanying drawings in Figure 1 is a plan view of the fender or wheel guard with the sills of the car and the pilotboard of the truck shown to illustrate the manner of mounting the wheel guard upon the car; Fig. 2 is a side elevation of the same; and Fig. 3 is a detail view of the transverse bar and its supports.

Referring by reference characters to this drawing, the numeral 2 designates the car platform and3 the sills. The swiveled truck frame is indicated at 4:, having the usual cross bar or pilot board 5, to which are secured hangers 6 provided with hooked or recessed portions 7 for receiving and supporting the rear cross bar 8 of the basket or scoop 8.

In order to relieve the scoop or basket as far as possible of shocks or. jars due to passing over rail joints or rough tracks, I have devised a very simple form of spring hanger shown clearly in Fig. 2. This hanger is constructed from a spring bar doubled upon itself, one arm or member 6" of the doubled portion being bolted to the pilot Specification of Letters Patent.

board, while the other arm or portion 6, which is spaced therefrom, carries the hook or recess 7 before referred to. In order to secure additional cushion efiiect or resiliency in a vertical direction, the upper portion of the hanger is carried horizontally for a suitable distance as indicated at 6. The rear bar 8 of the basket or scoop is retained in the recess in the hangers by the brackets 8", also bolted to the pilot board.

Centrallyof the basket or scoop and at the rear edge thereof is located a vertical arm 9 preferably of sheet metal with its lower end bent a quarter turn, and carried around the rear edge of the scoop, and be neath its lower face for a suitable distance, and to which it is suitably secured. Through this arm the scoop is normally held elevated and dropped when desired in the manner and by the means which will now be described.

To the upper end of the arm 9 is pivotally connected the rear end of a sheave carrying bracket 10, which is provided at its opposite end with pulleys or sheaves, or other antifriction devices, whichembrace between them a radial bar 11 which is curved on the are of a circle which has for its center the pivotal axis of the truck. This bar has an gularly turned ends 11 which are firmly seated in suitable holding clips or devices 12 on the ends of atransverse bar 12. This bar in turn is supported by L-shaped hangers 13 pivotally connected 'at their. upper ends with the car body, as, for instance, by securing them by means of pivot or hinge bolts 14 to the angularly turned ends 15 of a cross bar 16 secured to the sills of the car.

A spring 17 extending between bar 12 and a suitable fixed point on the car platform, tends to throw the parts just described forward and quickly lower the scoop and hold it down, when not restrained by the following described mechanism: Pivotally connected at their rear ends to the L-shaped hangers 13 are a pair of longitudinally disposed bars or links 18 which are pivotally connected at their front ends to the rocker plates or arms 19 and 19. These plates or arms 19 and 19 are, in turn, carried by and at or near the ends of square shaft 19 mounted in bushings 20 turning in suitable bearings 21 secured to or carried by the sills of the car. The bars or links 18 have their front ends seated in recesses or bifurcations in the plates 19 and 19, and the relation of the parts is such that when the members 19 and 19 are in the position shown in full lines in Fig. 2 the pivot 18 is slightly above a line extending between the squared shaft and the point of connection between the bars 18 and the L-shaped hangers. Further upward movement of the pivots 18 is pre vented by the engagement of the lower edges of the bars with the bottoms of the recesses, so that in this position the bars or links 18 coact with the plates or arms 19 to form struts. As the plates or members are held, by the relation of the parts referred to, from further backward rotation, it will be seen that the scoop or basket will be held locked until the plates or members 19 and 1-9 are rotated to carry the pivots 18 down past the dead center. This rocking is accomplished automatically by the trip frame 20 which has at its upper end a plate 21 provided wit-h. an elongated slot in which is slidably connected the front end of a rod 22, the rear endof which has a similar sliding connection with a slot in the plate or n1ember 19.

The connection between the rod and plate 21 is normally at the rear end of the slot, so that while the gate or trip frame may be swung forwardly without affecting the tripping connections, the rearward movement of the trip frame will at once pull forward upon the rod 22.

As the connection between the rear end of rod 22 and plate 19 is normally with the front end of the slot, the forward pull of rod 22 will rock the plate and square shaft until the dead center is overcome, when spring 17 will pull forward the parts and instantly drop the scoop. As soon as the scoop has been dropped, however, the plate 19 assumes the position shown in dotted lines in Fig. 2, in which position the connection with the slot is such that free farther rearward movement is permitted to the trip frame or gate so as to enable it to readily ride over an object such as a prostrated person without injury thereto. In order that the parts may be readily reset after they have been tripped, I provide a foottreadle 23 to the lower end of which is connected the one end of a flexible ele ment, such as a chain or cable, which passes over a pulley 24 and is connected at its other end with an arm 19 on the plate 19.

Having thus described my invention what I claim is:
