DAVID CHEW, OF' PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO ELTON VGt. IDELL, OF PHILADELPHIA, PENNSYLVANIA. i

CAR-FENDER.

To all whom it may concern:

Be it known that I. DAVID CHEW, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Car- Fenders, of which the following is a. specie fication.

My invention relates to improvements in car fenders, the object of the invention being to provide an improved construction of scoop or pick up fender normally elevated and forced downwardly by the action of a trippingfender which is engaged by a person or object on the track.

A furt-her object is to provide improved means for holding the pick up fender in its lowered operative position, when the tripping fender is moved to its rearward elevated position.

A further object is to provide a fender withan improved scoop or pick up member and improved laterally movable arms connected to the scoop and to a frame in rear of the scoop supporting the same, so that a netting receptacle is formed to hold a person or object picked up by the scoop member.

lilith these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view in side elevation illustrating my improved fender in normal set position, parts of platform and rdash being shown in section to illustrate the electric connections. Fig. 2 is a. plan view of the fender shown in Fig. 1. Fig. 3 is a view in front elevation 'of the tripping fender. Fig. 4 is a view in section on the line 4 4 of Fig. 1 with the netting removed for purposes of clearness. Fig. 5 is a perspective view of the scoop member of the fender. Fig. 6 is a view in section on an enlarged scale on the line 6 6 of Fig. 8. Fig. 7 is a view in vertical longitudinal section through the center of the fender, illustrating the latter in its position to pick up a person or object. Fig. S is a perspective view of the trip fender supporting shaft, and Fig. 9 is a diagrammatic rear elevation illustrating the Specification of Letters Patent.

electric connections between the several magnets.

1 represents a car and 2, 2, are brackets secured to the bottom 3 of the car and depending therefrom. These brackets 3 have 'upturned forward ends 4 supporting a shaft 5 extending transversely of the car and beyond the brackets 2. On this shaft 5, a scoop member 6 of my improved fender 4is pivotally mounted. Arms 31 are fixed to the shaft 5, secured to the scoop member 6 and project under the scoop member, acting as supports for the latter and for electro-magnets 28 hereinafter described.

The scoop member 6 constitutes a metal frame 7 connected by netting 8, and of a length to project beyond the railsk 9 of the track on which the car runs. Hangers 10 are secured to the bottom Vof the car and are positioned in advance of the brackets 2 to reinforce the bearings for the shaft 5, so that the fender is rendered sufficiently strong to withstand thefstrains to which it is necessarily subjected.

Laterally swinging arms 11 are pivotally connected at their rear ends to the bottom 3 of the car, as shown at 12, and these arms are connected by a netting 13 with the scoop 6 and with the brackets 2 forming a netting inclosure. It is to be understoodthat this netting is sufficiently slack to allow the scoop member to fall and also to allow the arms 11 to swing laterally, constituting a wide open mouth receptacle to receive a person or object. l

At the forward end of the car, depending brackets 14 are located and constitute bearings for a transverse shaft 15. A tripping fender 16 is secured to this shaft 15 and normally hangs in a vertical position, as clearly shown in Fig. 1, so that it will be struck or' engaged by a person or object on the track. This tripping fender maybe made in various'ways and I have illustrated it of the ordinary slat type.

The shaft 15 is provided with three upwardly projecting crank arms or pins 17 18, and 19, respectively. The crank arms 17 and 19 are adjacent the ends of the shaft 15, and are connected by links 20 with upwardly projecting crank arms 21 fixedly secured on the shaft 5, so that the rearwardv der 16 compels the scoop member 6 to move downwardly. The crank arm 18 is located intermediate the ends of shaft l5, and is connected by a link 22 with a pair of toggle levers 23. These levers 23 at their outer ends are connected to the arms 11, so that when the link 22 is moved forwardly, the arms 1l will be swung laterally as will be readily understood. p

As the tripping fender 1G is moved rearwardly and upwardly by Contact with a person or object, it will be moved to the po sition shown most clearly in Fig. 7 and will engage a pivoted catch 24 projecting through a slot 25 in the car platform in a position to be kicked by the operator to release the tripping fender whenever desired.

To prevent any possibility of the scoop member jumping up and down after it has been moved downwardly, I provide an arrangement of electro-magnets as will be now explained. Two of these magnets 26 are provided in the car platform and are adapted to attract metal blocks 27 on the tripping fender 16. Two electromagnets 28 are provided on the forward end of the scoop member 6 in position to engage the rails 9, and these magnets are connected in an electric circuit including a so-urce of supply 29 and a switch 30, as illustrated diagrammatically in Fig. 9. This switch is, of course, to be located in convenient reach of the motorman, and it is to be understood that the cire cuit to the magnets is maintained closed, so that as soon as the tripping fender is moved rearwardly, and the metal blocks Q7 approach the magnets 26, the power of the magnets 26 compels the completion of the movement of the tripping fender and the magnets 28 are attracted to the rails 9 and securely hold the scoop member 6 in its lowered position.

When it is desired to re-set the fender, it is simply necessary to manually release the catch 29 and throw the switch 80 to open the electric circuit, whereupon the tripping fender will fall to normal position, causing the scoop member 6 to be elevated to set position.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: l
