SAFETY APPARATUS FOR STREET-RAILWAY CARS.

SPECIFICATION forming part of Letters Patent No. 527,646, dated October 16, 189 4.

Application filed March 8, 1894- Serial No. 502,814. (No model.) i

To all whom it may concern.-

Be it known that we, JAMEs J. ANDREWS, of Inwood, in the town of Hempstead, and THEO- DORE MOTT, of Far Rockaway, in the county of Queens, btate of New York, have invented certain new and useful Improvements in Safety Apparatus for Street-Railway Cars; and we do herebydeclare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings,making apart of this specification, in which- Figure l is a side view representing our said invention with the parts in the position normally occupied by them'in anticipation of active operation. Fig. 2 is a like view of the same showing the position of the parts when brought into active operation. Fig. 3 is a like view of the same showing the position of the partsfolded as when not in use, and Fig. 4 is a plan or top view of the same with the parts in the position shown in Fig. 1.

This invention relates to that class of apparatuses which are designedto prevent or minimize danger to pedestrians and others from rapidly moving street cars propelled by electricity, cables, or other means which dispense with the use of draft animals.

It comprises certain novel combinations of parts whereby a person struck by an advancing car, instead ofbeing thrown down and run over, will be lifted and sustained by the automatic action of the apparatus and there: by withheld from injury from the advancing movement of the car.

A is the body, B the wheels, and 0 one of the platforms of a street car.

The structure of the car itself, its means of propulsion, &c., may be of any appropriate kind. x I

4 The front or dash-board of the car platform is shown at a. To the front of the platform and rearward part, a, being concave.

lowered position as shown in Fig. 1, they constitute a bracket which extends forward from thefront of the car.

G is what we term a trap, the office of which, in the operation of the apparatus, is to throw and receive free from harm any person who,

in the advance movement of the car, may be in danger of being struck thereby. This trap, G, has the form shown more fully in' the side views in Figs. 1 and 2, its lower and forward part, m, being of convex form, and its upper concave upper and rearward part of the trap whenthe parts are in position forfexpect'ed operation is in front of the dash-board, a,but

at such distance therefrom as to permit they said part to tilt backward as and for the purpose presently herein explained. From the convex lower and forward part of this trap projects downward an arm, 0, the lower end or outer end of the bracket bar, D. By this means the trap, G, is attached to, and made capable of turning upon, the said bracket bar. The trap isintended to be made of steel or other metallic ribbons plaited after the fashion ofbasket work to afford combined strength and lightness, said ribbon-work being surrounded by, and attached to, a suitable circumferential frame. When desired the trap may be'of any other suitable material, and its shape and contour may be modi-' fied within wide limits without departing from our invention. It is desirable'that the convex lower forward part, m,.of the trap be of moderate size in order that its efiect, upon striking the person of a pedestrian upon the track in front of a rapidly moving or unmanageablecar' be exerted as low down or near the ground as possible. Placed along the said convex part of the trap, in a direction transverse to thelength of the car and securely attached to the said partareany'de sired number of sections, 9, of india rubber hose or tubing. By reasonfof their elasticv This of which is pivoted as at, c", to the forward arm, 0, and the pivot by which the latter is connected with the bracket these sectionsof tubing cushion theimpact of the trap against the person of a pedestrian and thereby prevent serious bruising and injuries which otherwise would be likely to occur in the operation of the apparatus under said conditions of use. When desired instead of a single bracket rod, D, placed at or near the center of the front of the platform, two may be employed, placed at a suitable distance apart and projecting forward from the platform with the trap pivoted thereto by a trans- Y hereinafter set forth said spring coming in contact with the dash-board behind it, will act to prevent the sharp concussion which otherwise would occur to the trap by the sudden arrest of its said backward movement.

The parts being in the position hereinbefore explained and as represented in Fig. 1, the operation of the apparatus is as follows Assuming the advancing car to meet an obstacle, as, for example, a pedestrian upon the track, the convex lower part, m, of the trap strikes the person near the ground. This trips or throws the latter from his feet, and causes him to fall against the trap, G, with the result of swinging the latter backward upon its pivot, c", to a position sufficiently approximating the horizontal to hold and retain the person during any further advance movement of the car, the spring, f, as the trap approaches the limit of its backward motion coming in contact with the dash-board, a, and thereby softening the jar which would otherwise attend the cessation of the backward movement of the aforesaid upper or carrying part of thetrap.

It will be observed that the pivotal connection of the trap with the front end of the bracket bar being considerably below the outer adjacent surface of the trap, the latter is enabled to swing from a point near the ground while, at the same time a sufficient size is permitted to the lower and forward point of the trap to insure its efiective action in tripping and gathering the endangered pedestrian as just explained.

When it is not required that the apparatus remain in position for expected operation, the lifting rod, F, is drawn upward to disengage the brace, E, from its connection at a, b, with t the platform, and this upward movement being continued the bracket bar, D, is turned upon its pivot, a", the trap being by this means hauled up to the position shown in Fig. 3. The parts are intended to be so proportioned that when this last named position of the trap is reached, the pivot, a", will be at the top of the dashboard whereupon the lifting rod, F, may be turned backward and downward behind the dash-board as shown in said Fig. 3, thereby acting as a retaining device to hold the parts in their just described position.

It is of course to be understood that in practice, with double-ender cars, an apparatus will be provided to each end of the car, that at one end to be kept in position for expected operation while that at the other is in the folded position just herein described.

To maintain the lower edge or end of the trap, G, at asui'table distance from the ground, a loop, S,is extended from the under side thereof, above its point of pivotal connection with the bracket bar,D. This loop passes around and below the brace, E, so that when the latter is in the position shown in Fig. 1 the trap is prevented from tilting farther forward and consequently from striking the ground at its front or lower end. At the same time this loop is so arranged that it does not interfere with the backward movement of the trap, nor with its elevation to the position shown in Fig. 3.

What we claim as new, and desire to secure by Letters Patent, is-- 1. The combination with a car platform, a bracket apparatus extended forward f rom the said platform, and a trap, G, constructed with a convex forwardly extended lowerpart, m, and concave rearwardly extended upper part, n, of an arm, 0, extended downward from the said lower and convex part and means for transversely pivoting the arm to the front of the bracket, substantially as and for the pur pose herein set forth.
