MYR-ON J. AMIOK AND JOHANNES ROOS, OF NEW YORK, N. Y.

SAFETY-FENDER.

SPECIFICATION forming part of Letters Patent No. 535,184, dated March 5, 1 895. Application filed February 16, 1 894- Serlal No. 500,399. (No model.)

To @ZZ whom it may concern;

Be it known that we, MYRON J. AMIOK, a citizen of the United States, and JOHANNES ROOS, a subject of the German Emperor, both residents of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Safety-Fenders, of which the following is a specification.

Our invention relates to safety fenders for cars, and consists of acombination of devices by means of which the front edge of a scoop forming a part of the fender, is dropped automatically to the pavement in front of the car wheels by a good sized obstruction, which is thereafter picked up by, and carried in the scoop, until the car is stopped, thus preventing accidents.

In the accompanying drawings, Figure lis a longitudinal section of the lower end of a street car, showing the device attached to it in two positions. Fig. 2, is a bottom view of Fig. 1.

Upon a shaft a secured transversely under the bottom of a car, in front of the wheels by the brackets a', is rotatably mounted one end of the frame b of a scoop B, the covering of which consists preferably of close network h while the front edge h2 is preferably selected from an elastic material of a certain degree of stability, such as heavy strips of vulcanized rubber, and the like. Closely behind this strip and under the netting, are mounted, preferably on a shaft secured in the frame b, two rollers b3, which will touch the rails when the front end of the scoop is dropped (in a manner hereinafter described) and guide the front edge ofthe scoop in close proximity of, and almost touching the road-bed between the two rails, so that any object lying` upon the road is caught and carried upon the network of the scoop B.

The scoop B, is made preferably of the shape indicated in the drawings, and the front part of it is ordinarily held in an approximately horizontal position as shown in Fig. l of the drawings by means of two straps s, secured to the frame and passing from there upward over two rollers c c, secured closely under the bottom of the car, and from there to and partially around the drums d d i secured upon a shaft e, rotatably mounted in bearings e secured under the front platform of the car, their ends being secured to the peripheries of said drums. To the shaft e are also secured two sprocket wheels, one f near the center of the shaft e, and the otherf near one end of the shaft e which is provided at one or both ends with square heads for the attachment of a portable crank.

Upon a shaft g bent at one end and rotatably mountedy in bearings g secured under the bottom of the front platform is secured the pawlp, one end of which engages with the teeth of the sprocket-wheel f, and will prevent it from turning when the opposite end of the pawlp is supported by a segmental disk J1. forming part of the frame of a trapdoor or tlap h, hung in front of the car under the front platform and oscillating upon a shaft i secured parallel to a wheel axle at the bottom of the front platform. This flap h is made very light, the spaces in its frame being preferably filled with wirenetting, and it extends across the entire width of a car, being suspended preferably in an inclined position from the shaft '1l with its padded lower edge adjusted at a distance from the road bed and from a vertical plane through the shaft suficient to allow smaller obstacles to pass, but not `far enough to let a larger object pass without touching it. These objects will throw` it back sufficiently to trip the pawl p and thus relieve the tension upon the straps s, allowing the outer edge of the scoop B, to fall to the ground in time to catch the object and prevent its being ground by the wheels. A pawl 7a secured preferably on a bracket a engaging with a notch in the frame l) of the scoop, will prevent the latter from leaving the ground when once dropped, till the car has been stopped, insuring the safe scooping of any object in front of the car. Another pawl o secured upon the car frame in a position to engage the sprocket-wheel f will, when thrown in, hold the scoop B in the desired position, till the pawl p is thrown in position and the segment h slipped under its other end when the pawl 0 will be thrown back to a position shown in Fig. ll of the drawings, leaving the scoop free to drop when the automatic trap is released.

The operation in setting the scoop is then as follows: The pawl k being thrown out of contact with the frame b, and the pawl o into contact with thesprocket-wheel f aportable crank is placed upon the square end of the shaft e, and the shaft e is revolved in the direction indicated by the arrows in Fig. 1 of the drawings, and the motion is continued till the scoop is raised to a horizontal position as l shown in full lines in Fig. 1. The pawl p, which arrived at a position shown in dotted lines in Fig. 1, after springing of the trap, 'is now thrown in contact with the wheel f by pushing the trap door h backward and turning the shaft g, and is then secured by allow# ing the flap h to drop in position,thesegment h slipping under the opposite end of the pawlp and locking it, thus preventing the shaft e from turning and supporting the scoop in its raised postion by means of the straps,

will require larger objects, such as the body of a child, to spring the trap and drop the Scoop. l

The dropping motion of the scoop may be accelerated by a spring or springs as indicated in Fig. 1 of the drawings.

."In Fig. -1 'of the drawings the Working position of the scoop, after being tripped, is shown in dotted lines, and the position on the car while on the road, in full lines.

Having thus described our invention, what we claim,and desire to secure by Letters Patent, is

fIn a safety fender, the combination of an oscillating ap h with a shaft g carrying a pawlp, a shaftc, carrying drums and sprocket wheels, a pawl -0,-straps s, rollers c and ascoop B, asand for the purposes herein shownand described.

Signed at New York, inthe county of New York and Sta'te'of New York, this 15th day of February, A. D. 1894.
