CAR-FENDER.

Be it known that I, citizenof the United chester, county of MARTHA B. PFINGST, a States, residing in Dor- Suffolk, and State of Massachusetts, executrix of the estate of Louis Pfingst, who invented an Improvement in Car-Fenders, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to car fenders especially designed and adapted for use on the railways, and has for cars of electric street its object to provide a simple and eflicient bodily moved with relation to the carso as to proiect in front of the same when in use, and to e slid under the car platform when not in use, and. which in 1ts pro ected position 1s normally held elevated above the tracks but i is adapted to be released to drop down with its front end in close tracks F or this purpose, is mounted to slide in which has cooperating with t a locking device for holding the fender normally elevated abo th tr s The loe ng de c may be un er the c n r l f the mot nnan to r l ase he d supp rt and p rmit 1tt a toma ic ly u n d to lower the ender in o its op ra iv position, and sa lockmg device may be constructed so as to automatically lock the support by the operator proximity to. the the fender proper pivoted support inelely lifting the front end'of the fender.

These and other features of this invention will be pointed out in the claims at the end of this specification.

with side bars 10, 12, end bars 13, 14:, longitudinally extended intermediate bars 15, preferably curved at their rear ends to form a basket, and cross bars 16 secured to and reinforcing the said longitudinal bars.

The fender proper is mounted to slide in pivoted supports herein shown as castings or bars Z) having on their inner sides longitudinally extended slots 0 in which the side bars l0, 12, of the fender frame are inserted so as to slide therein, said castings or bars being mounted upon a rock-shaft (Z located above the slots 0 and journaled in bearing blocks 6 secured as by bolts f (see Figs. 1 and S) to hangers or straps g from the an derside of the platform it of the car i (see Figs. 1 and 5).

The rock-shaft cl turning by locking made as herein shown and consists of cooperating members,- one member being shown as levers or latches 20 fast on a rockshaft 21, which is supported by arms 22 secured to the straps or hangers g by bolts 2-3 and clamping block 24: (see Figs. 3 and 7). The arms 22 extend rearwardly from the hangers g, and the levers or arms 20 extend from the rock-shaft 21 toward the said hangers, and are provided at their free ends with notches or recesses 25 on their under sides to receive the upper ends of upright arms or dogs 26 fast on the rock-shaft (Z and constituting the other member of the locking device.

The locking levers or arms 20 are provided at their ends with curved or cam shaped under surfaces 28, for a purpose as will be described.

The locking dogs 26 enter the recesses 25 in the locking levers 20 when the fender and its pivoted supports are in a substantially horizontal position as represented in Fig l, which position may be termed the elevated or inoperative position of the fender, and the locking levers may be disengaged from the lockingdogs as herein shown by means of a foot rod or pedal bar 30, which is extended down through the platform It and engages a crank or arm 31 on the rock-shaft 2L By reference to Figs. 1 and 4, it wlll be seen that depression of the rod by the is normally held from foot of the motorma'n or other operator rocks the shaft 21 so as to lift the front end of the locking levers 20 and disengage them from the locking dogs 26, thereby leaving the rock-shaft (Z free to be turned by the weight of the fender a, so that the latter s lowered or dropped into its operative or inclined position shown in Fig. 2.

After the fender has performed its function of picking up an object or preventing 1t from passing under the car, it can be restored to its elevated position by the operator lifting its front end up into the horizontal position shown in Fig. 1. As the front end of the fender is elevated, the shaft d is rocked so as to bring the locking dogs 26 into engagement with the cam surfaces 28 of the levers 20, and on the continued lifting of the fender, the locking levers 20 are lifted by the dogs 26 until the latter have been brought under the recesses 25, whereupon the said levers drop and automatically lock the fender and its rocking support with the fender in its normal position shown in Fig. 1.

I have herein shown the latches or locking devices as manually operated, but it is not desired to limit the invention in this re spect. WVhen it is not desired to use the fender, as for instance the one at the rear end of the car, it can be slid or pushed in under the rear platform by the operator, the side bars 10, 12, of the frame sliding in the channels or slots 0 on the inner sides of the pivoted supports 5.

If desired, the weight of the fender proper may be depended upon to prevent its backward movement inthe pivoted supports when the fender in its lowered or operative position strikes the object on the track, but if desired positive stops may be provided for this purpose. In the present instance, such stops are shown as cranks or arms 40 on a rock-shaft 41 supported by the castings or bars 22 and provided with handles 42 by which said rock-shaft can be turned from either side of the car so as to lower the cranks 40 into the path of movement of lugs or projections 140 on the side bars of the fender proper. When it is desired to push the fender under the platform, the handles 42 may be turned so as to lift the cranks 40 clear of the side bars of the fender and when the fender is in its forward or operative position, the cranks 40 are lowered into the path of movement of the side bars of the fender and prevent backward movement of the said fender.

The fender may if desired be provided at its front end with a buffer 45 of wood, rubber or other suitable material.

When the fender has been lowered into its inclined or operative position, the motorman can release the pedal 30 and allow the levers 20 to drop into position to have their cam surfaces 28 engaged by the dogs 26, which position may be determined by lugs 50 on the levers 2O engaging ribs or pro jections 51 on the arms 22 (see Fig. 7
