Application filed May .7, 1910. Serial No. 560,096.

[0 all whom it may concern Be it known that I, HENRY W. BODEN' omen, a citizen of the United States, and a resident of the city of Springfield, in the county of San'gamon and State of Illinois, have invented certain new and useful Improvements in Street-Car Fenders, of which the following is a specification, reference being had to the annexed drawings.

This invention relates to automatic car fenders of the class set forth in U. S. Patent, #888,578, automatic car fender, granted to me May 26, 1908.

The main purpose of this invention is to provide a fender to pick up and carry persons or things on the track immediately in front of'a moving car.

More particular purposes are to provide a power-actuated pick-up frame adapted to be projected forwardly of the car; to provide a yielding guard-frame operatively connected with the pick-up frame; and to provide means whereby the pick-up frame, after it has been projected, may be returned toits initial position, in readiness for the next operation without stopping the car.

Figure 1 is a side elevation of the car fender in position on the front end of a car. Fig. 2 is a top plan of the car fender. Fig. 3 is an enlarged combined elevation and sectional view, showing the main structure of the car fender in side elevation and the pneumatic cylinder in longitudinal section. Fig. 4: is a vertical section on the

line

4, 4, of Fig. 3. Fig. 5 is an enlarged view of the shaft which supports the guard-frame. Fig. 6 is an enlarged transverse section on the line 6. 6. of Fig. 3 and Fig. 7 is an enlarged sectional view of the four-way valve.

Similar reference numerals designate like parts in the several views.

Downwardly extending front brackets 2 and shorter downwardly extending rear brackets 3 are secured on the under side of the frame 1 of the car platform. Parallel inclined guide rails 4 are rigidly connected with the

brackets

2 and 3. Hangers 5 are rigidly secured on the under side of the frame 1. A shaft 6 is mounted to oscillate in suitable bearings on the hangers 5. Bigidly secured on each side of the center of the guard frame are inwardly directed guard supports 11, having integral fingers 11, and also having integral members 11",

connected with the guard frame by any suitable means, not shown. Arms 7 extending downwardly and forwardly, are secured on the shaft 6 and have Vertical sockets 7 accommodating downwardly extending fingers 11 at the inner ends of the guard-supports 11.

The guard frame, designated as a whole by the numeral 8., is mounted on the guard supports and the upper end of the guard frame is adjacent to the front end ofthe car platform. The guard frame comprises a suitable number of downwardly inclined slats 9 secured on upper and lower trans verse bars 10 and spaced apart to prevent the passage of any large object between them.

Fixed

hangers

12 and 13 support an inclined cylinder 14, centrally under the car. The front end of the cylinder 14 is somewhat lower than the rear ends of the guide rails 4 and the general inclination of the cylinder is parallel to the guide rails. The piston 15 connected with the rod 16, is adapted to slide in the cylinder 1%, and the forward end of the piston rod 16 is pivotally connected with a transverse shaft 17. The ends of the shaft 17 are secured on the parallel veritcal arms .18. Journaled 0n the outer-side of each arm 18 is a pair of rotative rollers 19, one above, and one below each guide rail 4:, and the rollers guide the movement of the arms 18 on the guide rails 4 respectively. The lower ends of the arms 18 are connected by a horizontal transverse bar 20.

The pick-up frame, designated as a whole by the numeral 21, is secured on the underside of the bar 20. The pick-up frame comprises a number of parallel slats 22 (Fig. 4:) connected at their front ends by a transverse bar 23. The width of the pick-up frame is somewhat greater than the gage of the track in order that when the pickup frame is projected forwardly and depressed its frontend will slide on the rails in advance of the car. i

A rearwardly extending downwardly curved arm 24 is secured on the loar 20. A revoluble roller 25 is supported near the lower end of the hanger 12. When the frame 21 is pushed rearward the curved part of the arm 24 slides under the roller 25, and the roller depresses the arm and causes the frame to occupy the substantially horizontal position shown in Fig. 3. w

'frame in its retracted position.

A four-way valve 26 suitably supported under the car platform has a stem 26 and a plug 26 (Fig. 7) secured on the stem.

A tank 30 (Fig. 1) containing compressed air is supported on the underside-ofthe car.

A pipe 27 connects the valve 26 with the air tank 30, a pipe 29 (Fig. 2) connects the valve 26 with the rear or pressure end of the cylinder 14, and a pipe 29 connects the forward or exhaust end of the cylinder with the valve 26.

A forwardly projecting lever 31 is secured on the valve stem 26 A detent 32 pivotally mounted on the'under side of the platform 1 is situated above and extends over the front end of the lever 31 to normally keep the'plug of the valve in position to maintain air pressure through the pipe 27, the valve 26 and the pipe 29 to act on the front end of the piston 15 to normally keep the pick-up An inclined arm 34: is secured on the shaft 6 and a link 33 connects the arm with the detent 32.

The spring 35 has one end secured onthe under side of the car platform and its other end connected with the arm 34:, and the spring acts to normally keep the arm in the rearwardly inclined position shown in Fig. 3, and thereby keep the shaft 6 in such position that the guard-frame 8, mounted on the arms 7, willvnormally occupy the extended position shown in Fig. 3.

- A spring 36 has one end connected with any suitable stationary support and the other end connected with the lever 31 and the spring acts to pull the lever upwardly. Upward movement of the lever 31 causes the plug 26 of the valve 26 to turn into position to permit air from the tank 30 to pass through the pipe 27 to and through the valve 26 and to pass through the pipe 29 to the interior of the rear part of the cylinder 1. 1, and act on the rear end. of thepiston 15 to cause the piston to slide forwardly in the 7 cylinder, and thereby cause the pick-up frame to be projected forwardly.

The lever 38 secured on the stem 26 of the valve 26 supports a vertically movable plunger 39 extending upwardly through the car platform. Y

After the pick-up frame has been projected forwardly the retracting of the pickup frame may be accomplished by the operator pressing with his foot on the upper end of the rod 39 to depress the lever 38 to cause the application of air to the front end of the piston 15 within the cylinder 14, and there by cause rearward movement of the piston to effect retraction of the pickup frame.

The air in the cylinder 14 applied on the frontend of the piston 15 acts to keep the p1ckup frame in its retracted position and the piston rod' 16 pulling on the arms 18 causes the rearwardly extendingcurved part of the arm 24: to bear against the roller 25 with the result that the rearward pull of the piston rod will cause the front end of the pick-up frame to tip upwardly so that the upper surfaces of the slats 22 will bear firmly against the lower edge of the stationary transverse bar 41 at the lower ends of the hangers 2 and thereby limit upward movement of the front end of the pick-up frame and prevent vibration of the pickup frame by reason of the jolting or oscillation of the car.

A stationary horizontal plate 4:0 has a notch 10 accommodating the upper part of the lever 34, and the walls ofthe notch limit forward or rearward movement of the lever 34. I

Under ordinary conditions the pick-up frame remains wholly retracted with its front end clear of the track rails.

The guard frame 8 normally occupies the forwardly extended position shown in Fig. 1.

The spring 35 is strong enough to normally keep the guard frame in its extended position, but if the lower part of the guard frame strikes a stationary or weighty object, the spring will stretch and permit rearward movement of the lower part of the guard frame, thereby causing forward movement of the upper end of the lever3 1, and the lever 3-1 will pull on the link 33 to cause the detent 32 to swing forwardly andrelease the lever 31; whereupon'thespring 36 will pull the lever 31 upwardly to rotate the plug 26 to open the valve 26 to cause the I air in the front part of the cylinder. 1% to exhaust through the pipe 29 and the valve 26 to the atmosphere and also to cause air from the tank 30 to flow through the pipe 27, the valve 26 and the pipe 29 into the rear part of the cylinder 11 and act on the piston 15 to cause the pick-up frame to slide forwardly. The first part of the forward movement of the pick-up frame will cause the curved arm 24: to withdraw from under the roller 25 and thereupon the forward end of the pick-up frame will fall upon the rails, and continued forward movement of. the piston will cause the pick-up frame to slide forwardly 011 the rails and beyond the lower end of the guard fender, in position to pick up a person or object lying on the track, (as shown by dotted lines in Fig. reason of the downward inclination of the pickup frame as it is projected forwardly it is iinpossiblefor it to rise over the person or obstruction on. the track, but'on the contrary it is forced under and picks up the person or thing as it slides along the rails, and carries same safely until the car can be'stopped.

hen the person or thing has been removed from the pick-up frame the operator 7 will with his foot press the plunger 39 downward upon the lever 38 to cause partial rotation of the plug 26 to cause it to occupy the position shown in Fig. 7 and to cause the lever 31 to move downwardly so that the forward end of the downwardly moving lever 31 will engage with the rear edge of the detent 32 to cause it to turn on its pivot sufliciently to permit the end of the lever 31 to pass the elbow of the detent, and thereupon the spring 35 acting on the arm 34, which is connected with the detent 32, will cause the lower part of the detent to move rearwardly and extend over the forward end of the lever 31, to hold the valve plug in the position shown in Fig. 7.

hen the plug 26" is in the position shown in Fig. 7 air from the rearward part of the cylinder 14 will exhaust through the pipe 29 and the valve to the atmosphere and air from the tank 30 will flow through the pipe 27 to the valve 26 and from the valve through the pipe 29 to the front end of the cylinder 1st and will act on thepiston 15 to slide it rearwardly to cause complete retraction of the pick-up frame, and the pick-up frame will be held in its retracted position by the air pressure on the piston. This rearward movement of the pick-up frame will cause the arm 9A to engage on the roller 25 to elevate the forward end of the pick-up frame and hold it firmly against the transverse bar 41.

I have shown and described two guide rails at supporting the rear part of the pickup frame and guiding its rearward movement, but it is obvious that one or moreguide rails may be used without departure from my invention. It is obvious also that other details of construction may be varied without departure from the principles of the invention.
