ELWYN G. HT IT OF PT- TTAADELP TA PENNSYLVANIA.

CAB-FENDER.

Application filed July 8, 1914.

To all whom it may concern:

Be it known that I, ELwYN G. HILL, 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 specification.

My invention relates to improvements in car fenders, the object of the invention being to provide a pivoted scoop fender normally supported in an elevated position and caused to drop to operative position when an improved tripping fender contacts with the person or object on the track, or when the same is caused to move by the action of a dog kicked by the motorman.

A further object is to provide an improved mechanism of the character stated in which the movement of the tripping fender operates to apply the air brakes and open the electric circuit so as to insure the stopping of the car as well as the operation of the fender.

A further obiect is to provide improved means for holding the scoop fender in its lowered operative position, and provide improved means for raising the scoop fender to set position.

A further object is to improve upon the construction set forth in Patent No. 1,0415% granted to me November 19, 1912.

ll itli 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 fragmentary view in side elevation illustrating my improved scoop fender inposition to pick up a person or object on the track. Fig. 2 is a fragmentary view in transverse section on an enlarged scale on the line 22 of Fig. 1 showing the side frame in its inward position. Fig. 3 is a fragmentary plan view of the car platform illustrating the plunger for elevating the scoop fender and the do": to be operated by the motormans foot. Fig. i is an inverted plan view showing the scoop fender in its set position. Fig. 5 is a view in section on the sta gered line of Fig. 4:. Fig. 6 is a view in trans e se sect on on the staggered line 66 of Fig. i. Fig. 7 is a fragmentary view in longitudinal section on the Specification of Letters Patent.

line 7-7 of Fig. d. Fig. 8 is a fragmentary view in longitudinal section on the line 8-8 of Fig. d, and Fig. 9 is a fragn'ientary view in longitudinal section on the line 9-9 of Fig. 4.

1 represents the bottom of a car supporting a body 2, and at the forward end of the car. constituting a platform 3, as is common in the art. Brackets 1, 4: are secured to the bottom 1 of the car in front of the wheels l3, and these brackets pivotally support my improved scoop fender 6. The scoop fender 6 comprises a main frame consisting of four transversely positioned tubular members 7. 8, 9, and 10, connected at their ends by angle barsll and covered by a netting 12 The angle bars 11 are of general L-shape with the shorter member of the angle projecting upwardly.

Movable side sections 12 are provided on the scoop fender and consist of angle bars 13 corresponding in shape to the angle bars 11, and having rods 11 secured thereto. Four of these rods 14: project into the

tubular members

7, 8, 9, and 10, and two of the rods 11 project through openings 15 in the angle bars 11 and are provided with enlargements 16 on their inner ends to limit the outward movement of the side frames.

The rods 11 in the tubular members 7. 9, and 10, bear against coiled springs 17, which exert a continuous outward pressure. tending to move the side frames outwardly and expand the scoop fender laterally. The rods 11 in the ends of the member 8 are connected to flexible devices 18, the latter being passed around pulleys 19 and out through a slot 20 in the rear wall of the tubular member. These flexible devices 18 connect to an operating cable 21 which is connected between its ends to one member 22 of a bell-cranklever 23. The cable 21 extends rearwardly from the bell-crank-lever around the pulley 24, and thence forwardly to a drum 25 which has rotary mounting in brackets secured to the bottom of the car platform 3., and on which drum the cable is wound.

A c1. wed arm 27 fixed to the scoop fender 6, extends rearwardly therefrom. and is nositioned below and engaged by the member 28 of the bell-crank-lever 23. so that when the cable is woundupon the drum. it will exet a pull u on the s de f ames 2 to d a w them inwardl". and ll also sw n the bell-crank-lever 93 on its fulc um. the me ber 28 pressing downwardly upon the curved arm 27, causing the scoop fender to elevate to its normal set position, as shown in Fig. 5. When the scoop fender falls, the arm 27 will press the member 28 of the bellcrank-lever against the supporting bracket 29, and limit the downward movementof the fender,

The bell-crank-lever 23 is supported ina bracket 29 secured to the car bottom 1, and the member 28 of said lever controls the operation of a wedge block 30 to lock the scoop fender in its lowered position, as will now be explained.

The block 30 is connected by a flexible device 31 with the bell-crank-lever 23, said flexible device being passed over a pulley 32 above the block, and-while I have illustrated a housing 33 toaccommodate this pulley and block, it is to be understood that any suitable mounting may be provided in accordance with the construction of the car.

The block 30 is movable against the front face of one of the brackets 4i, and is guided between flanges 34: on the bracket. The forward edge of the block engages one of the bars 11, and while said bar 11, at its rear end, is at an incline when the scoop fender is in set position, as shown in Fig. 5, when the scoop fender falls or drops to operative position, this portion of the bar 11 is approximately parallel with the front face of the-bracket, so that the block 30 can fall into position and prevent any pivotal movement of the scoop fender. This position of parts is clearly shown in Fig. 1, where it will be noted that the block is so positioned that the scoop fender cannot rise, and hence the latter is held securely so as to pick up a person or object and prevent the wheels from passing-over the same.

When the drum 25 is turned to raise the scoop fender, it causes thebell-crank-lever 23 to operate, and through the medium of the flexible device 31, the block is elevated to the position shown in Figs. 5 and 9. It is, of course, to be understood that when the scoop fender falls, the slack in the cable willper'mit .the side frames 12 to spring outwardly, and that these side frameshave independent vnettings 35 covering them, which nettings spread out as the frames move outwardly, and provide asupport for a person or object.

36 represents a vertically movable plunger which is movable in a sleeve 37 in the platform.3. This plunger 36 is providedwith a rack 38 which engages a pinion 39 fixed to turn with the drum 25, so that the downward movement of the plunger compels the drum 25 to turn in adirection to wind the cable 21 thereon. This plunger is operated by the. downward pressure of the motormans'foot,1so that; he. can by this. movement,

raise the scoop fender to normal set position.

-of the tripping fender.

A; tripping fender 40 is pivotally supported in brackets 4L1 secured to the car platform and located at the front of the platform in position to be struck by a persecuredto the bottom of the car platform, and at lts rear end is recessed, as shown at 4:7, to receive the plunger 36. The plunger 36 is provided in its front face with a recessl8 into which the plate K L5 projects,

and which holds the plunger in its lowered position.

The plate 4:5 is caused to move rearwardly by the downward and forward movement In other words, the tripping fender tends always to swing downwardly by gravity to a vertical position, and hence when permitted, will force the plate 45 into locked engagement with the plunger 36, hence when the plunger is .forced downwardly toelevate the scoop fender 6, as soon as the plunger reaches a predetermined poiDt, the plate 45 will spring into the recess 4-8 and hold the parts in set position.

When a personorobject is struck by the lower cross bar 49 of the trippingwfender .40, said tripping fender will be caused to move rearwardly, and pinion 4-3 willimove the plate l5forwardly outof the recess 48 and allow thescoo p fender 6 to drop.

To insure a quick drop of the scoop. fender6, Iprovide a spring 50 which is coiled around the tubular member 9, and at one end bears against .the; tubular member 10 of the scoop fender, and at its-other end is connected to a bracket 4:, although this spring may, of course, be otherwise mounted to assist gravityin moving the scoop fender quickly to operative position.

51 represents an air pipe constituting a part of an ordinary air brake system having a valve 52 with a crank arm 53. secured .tothe stemof-the valve, and connected by a link with the lowerrod e91 of thetripping fender 4,0, so that when the tripping fender moves rearwardly it causes, the, valve to moveand apply the brakes.

'55 represents an electric switch arm con nected by wires 56 with the electric motors of the car. .The switcharm is adapted to engage contacts 57 on a bracket 58 to which supply wires 59 are secured. rhlink 60 connects the switch arm with the lower rod 49 of the tripping fend-er,.so that when the tripping fender moves rearwardly, the switch arm 55 is causedto move in a directionto open the electric circuit and shut off the upply of current to the motors. I It will therefore be noted that when the tripping fender is operated, it not only causes the scoop fender 6 to drop in position to pick up a person or object, but it also causes the brakes of the car to be applied and the sup ply of current to be shut off, thereby preventing accidents even though the motorman may fail to promptly do his duty.

On the platform 3 I provide a dog 61 secured to a shaft 62 projecting through the platform and having a finger 63 at its lower end in position to engage the rear edge of the plate 45. The motorman can kick this dog 61, which will compel the plate 45 to move forwardly out of the recess 48 of the plunger 86, and hence allow the scoop fender to drop before the tripping fender strikes a person or object. 1 hence provide two methods of operation, one under the control of the motorman, and the other operated automatically by contact of the tripping fender with the person or object on the track.

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 my self at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.
