GEORGE ERNEST WRIGHT, OF EAST FAIRFIELD, VERMONT.

CAR-FENDER.

SPECIFICATION forming part of Letters Patent No. 721,350, dated February 24, 1903.

Application filed April 21, 1902.

To all whom it may concern:

Be it known. that I, GEORGE ERNEST WRIGHT, a citizen of the United States, re= siding at East Fairfield, in the county of Franklin and State of Vermont, have invented a new and useful Car-Fender, of which the following is a specification.

This invention relates to certain improvements in car-fenders, and has for its principal object to construct a fender for application to street-railway cars in which the upper surface or receiving-platform of the fender is adapted to travel rearwardly for the purpose of picking up and conveying to a place of safety a person or other object in the path of the traveling car.

A still further object of'theinvention is to provide the traveling platform with pins for engaging the clothing of a person and with means for effecting the disengagement of the pins from the clothing after the person has been removed to a position of safety on the fender.

A further object of the invention is to so arrange the fender and its operating mechanism that while the fender may be so adjusted as to remain in operative postion in front of the car the traveling platform Will not be moved untilits operating mechanism is adjusted by the motorman or other attendant on the car, such operating mechanism being under the control of the motorman, so that he may readily start the platform into operation when the car approaches a person or other object and stop its movement when the person is resting on the fender.

A still further object of the invention is to so construct and arrange the fender-supports as to permit of the adjustment of the fender either in front of the car or to a position under the front end of the car when the latter is used as a trailer or is running in reverse direction.

With these and other objects in View the invention consists in the novel construction and arrangement of parts hereinafter described,illustrated in the accompanying drawings, and particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective View of a car-fender constructed in accordance with my invention, showing the same Serial No. 103,987. (No model.)

adjusted to operative position in front of the car. Fig. 2 is a longitudinal sectional elevation of the same, illustrating aportion of the .car in section and showing the fender-operating mechanism in position to actuate the fender. Fig. 3 is a side elevation of the fender, illustrating the same adjusted to a position under the car. Fig. 4 is a sectional plan View of the device on the line 4 4 of Fig. 2. Fig. 5 is a transverse sectional elevation of a portion of the fender on the line 5 5 of Fig. 4.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

The side beams 10 ofthe car are provided on their inner faces with horizontally-disposed slots 11 for the reception of the upper bars 12 of the fender-frame, said bars being adjustable to permit the movement of the fender-frame to a position. in front of the car, as illustrated in Fig. 2, or to a position under the car-platform, as shown in Fig. 3. When thcrfender is in operative position and extending out in front of the car it is held from movement by a pair of spring lockingdogs 14, carried by the bars 12 and engaging the front ends of the side beams of the car.

The fender-frame comprises a pair of side plates 15, depending from the bars 12, and two or more transversely-disposed connecting bars 16; At suitable intervals in the width of the fender are arranged pairs of guide-plates 17, carried by the bars 16 and held in proper spaced relation by fillingblocks 18. The plates 17 are curved upwardly at their rear ends, and each pair of .plates serves as a guide for a link-belt 20,

passing over sprocket wheels 21 and 22, mounted on

shafts

23 and 24, respectively, at the front and rear portions of the fenderframe.

The link-belts 20, of which there maybe any desired number, are each provided with a plurality. of comparatively short pins or teeth 25, adapted to engage in the clothing of a person and positively lift the person from the road-bed to the fender. As the person or other object is moved toward the rear end of the fender contactwith the elevated portion of the guide-plates 17 will cause the disengagement of the pins or teeth 25 from the clothing and allow the person to remain in a safe position until the car is stopped. The side plates may be elevated above the pins or teeth at some little distance in advance of the rear portion of the fender, or the inclination may be gradual in order to permit of the ready disengagement of the pins or teeth from the clothing.

Near the rear end of each of the side plates 15 is a vertically-disposed slot 26 for the reception of the end of a transversely-disposed shaft 27, said shaft being normally held at the top of the slots by tension-springs 28, extending between the shaft, and fixed hooks or supports 29 on the side plates of the fender-frame. On the shaft 27 are secured a pair of frictionwheels 30, so situated that when the shaft 27 is depressed they will come into contactwith the trafiic-rail and be re'volved by frictional contact therewith. On one or on both ends of the shaft 27 is secured a gear-wheel 32, intermeshing with a pinion 33 on the shaft 24 and serving through the medium of said shaft and the sprocket-wheels 22 to set the link belts into operation.

At the center of the shaft 27 is an annular groove 34, adapted to receive a shoe 35, mounted on a vertically-guided bar 36, extending up through an opening in the front platform of the car and provided with an enlarged pin 37 within convenient reach of the foot of the motorman or other attendant. The lower portion of the rod is guided by a bracket 38, and said rod is normally held in elevated position by the spring 40.

Underordinary conditions the fender-frame is held in front of the car, as illustrated in Fig. 2, the shaft 27 being elevated and the wheels 30 held out of operative contact with the traflic-rails. The tender, however, is in operative position and could operate in the usual way without any attention on the part of the motorman. On approaching a body or other object on the track the motorman depresses the rod 26 and forces the shoe 35 into the groove 34 of shaft 27. Further downward movement depresses the wheels 30 into contact with the traffic-rails and sets the link belts into motion, the teeth or hooks of such belts positively engaging and lifting the body from the track and carrying the same to a position of safety at the rear portion of the fender, the contact of the body with the elevated portion of the guiding-plates serving to automatically disengage the teeth from the clothing in the event of the neglect of the motorman to remove his weight from the knob 37. When pressure on the knob is released, the shaft 27 is moved to its elevated position by the springs 28.

When it is not desired to move the fender, it may be moved to the rear by disengaging the dogs 14 and sliding the bars 12 rearwardly in the guiding-slots 11, the fender being moved under the bottom of the car to the position illustrated in Fig. 3.

A fender constructed in accordance with this invention will last for a considerable length of time owing to the fact that there is no wear on any of the parts except when the fender is actually engaging with a person or other object, and at the same time the position of the fender is such that it will act as an ordinary fender should the motorman neglect to set the link belts into operation.

' While the construction herein described, and illustrated in the accompanying drawings, is the preferred form of the device, it is obvious that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.
