CAR-FENDER.

SPECIFICATION forming part of Letters Patent No. 520,354, dated May 22, 1894. l

Application filed December 8, 1898. Serial No. 493,144. (No model.)

To @ZZ whom t may concern:

Be it known that we, BERNHARD CRON and WERNER voN MNoHHAUsEN, both of New York city, New York, have invented an Im- 5 proved Car-Fender, of which the followingis a specification.

This invention relates to a fender for street cars, which is so constructed that when it strikes a human or other body, it is autom matically thrown forward, to project the same into a net between the fender and the car.

In the accompanying drawings Figure 1 is a side elevation, partly in section, of our irnproved car fender; Fig. 2 a bottom view there- 15 of, with the lock case open; Fig. 3 a vertical cross section on line fr, cv, Fig. l; Fig. 4 alongltudinal section on line fy, y, Fig. 3; Fig. 5 a plan of part of the fender, with the car bottom removed, and Fig. 6 a top view of the 2o' lock case.

The letterA represents a car, provided with a pair of tubes, a, a, that extend longitudinally beneath the bottom, to a short distance from the dash board. These tubes contain 2 5 the telescoped rods ct', a', and springs a2, the latter having a tendency to throw the rods outward, a considerable distance beyond the front end of the car. To the forward ends of the rods a', there is hinged by pins surround- 3o ed by coiled springs (Fig. 5) a frame b, havinga pair of rearwardly extendingV eyes b. This frame is attached to a buffer c, by means of eyes c', through which the frame passes and is surrounded by springs c2, so that a 3 5 yielding connection between frame and buffer is established. The buffer may be provided with a padded striking edge c3, of rubber or other material. The rods a', are surrounded back of the buffer by rings cZ,to which a net 4o d, is attached, said net being also attached to the rear edge of the buffer and the front edge of the car. Y

To the front of the car body, there is secured, below the center of the platform, a

45 spring catch adapted to engage the eyes b. Normally the buer is thus locked to the car and the net is folded, but when a body strikes the buffer, the catch is automatically released and thus the springs d2, are free to throw the 5o buffer forward and to spread the net. The body that has been struck, will in this way be precipitated over the buffer and into the net, to escape serious injury.

The spring catch consists of a pair of jaws c, within lock case e', and adapted to be held 55 normally in engagement with eyes b', by the springs e2. Centrally between the jaws e, there is secured within the lock case, a slotted cylinder e3, containing a spiral spring e, which is stronger than thespringsez. Through 6o the rear end of the cylinder e3, there projects a plunger e5, in contact with the ends of jaws e, and provided with a pin e6, projecting upwardly through the slotted cylinder and out of the lock case. The pin e6, is engaged by the 6 5 hook-shaped rear end of a spring lever f, the curved front contact edge f', of which projects slightly in front ofthe car and is adapted to be struck by the buffer. Normally no pressure is exercised upon this lever by the 7c. buffer and its rear hook-shaped end will engage pin e5, and will hold the spring e4, compressed (Fig. 2) so thatthe springs e2, are free to throw the jaws e, outward and into engagement with the eyes b of the buffer. In 75 this way the buffer is securely locked to the car. As soon however, as the buffer strikes an object, it is forced back slightly, against the action of the springs d2, and against the contact edge f', of lever f. In this Way the 8o lover will be vibrated to release pin e6, when the spring e4, will at once throw the plunger ebackward, to oscillate the catches e, and withdraw them 'from eyes b', (Fig. 5.) The buer being thus unlocked from the catch S5 and from the car body, will be at once pro` pelled forward by the springs a2, to spread the net and catch the body in the manner already described.

After the buifer has performed its work, it is 9o thrust back by hand and the lever f, is brought back into its normal position by means of a foot bar g, adapted to operate au elbow lever g', and which in turn engages the pin e6, above the lock case e', (Fig. 6.) The foot bar pro- 95 jects upward through a slot in the car platform, and when it is moved laterally, it will vibrate elbow lever g', to move the plunger e5, forward, by means of pin e6, and to compress spring et. small spring f2,be thrown back into engagement with the pin e6, so asto lock the spring The lever f, will now, by a roc e4, in its compressed position,while the spring e2, will be free to throw the jaws e, outward and back into engagement with the eyes b. Thus all the parts will be placed again into the normal position, shown in Fig. 2. The foot bar g, may be locked temporarily, by a pressure upon the button 7L', of a spring catch h, (Fig. 3,) that will then engage a pin g2, of the foot bar. As long as the foot bar is thus locked, its lever g', will hold the plunger e5, locked in its forward position and preventthe mechanism from being set O, by'press-V ure upon lever f. This locking attachment is desirable, because when the car strikes trucks and similar inert objects, the buffer should not be projected forward. As soon as pressure on button 7L', is released, the apparatus is again put into working order.

l. The combination of a car witha catch,a movable yielding buer engaged by the catch, propelling springs and a spring actuated rod put in action by the rearward movement of the buffer and adaptedrto open the catch and liberate the buffer when pressed backward, substantially as specified.

2. The combination of a car with apair of tubes, a buffer having rods that are telescoped by said tubes, springs for throwing the butter outward and an automatic catch for locking the buer to the car, and a spring bolt to release the same upon impact of an object on the track with the buffer substantially as specified.

3. The combination of a car with an independently movable buffer, spring jaws secured to the car and engaging the buffer, and a lever adapted to be operated by concussion with the louder and to oscillate the jaws, substantially as specified.

4. The combination of a car with an independently movable buffer, spring jaws, a. spring plunger operating the same, a lever 0perated by concussion with the buffer'and engaging the plunger, and with a foot bar, for setting the plunger, substantially as specified.

5. The combination of a car with an independentl'y movable buffer, spring jaws, a spring plunger, an operatinglever .a foot bar and a catch for locking the foot bar,substan tially as specified.

6. The combination of a car with a pair of tubes, a spring buer having rods telescoped by the tubes, a catch on the car body and a lever operating the catch and adapted to be vibrated by contact with the buffer, substam tially as specified.

7,'The combination of a car with a. pair of spring propelled rods, a frame hinged to the rods, a spring buffer-secured to the frame and a catch for locking the buffer to the car, substantially as specified.
