CAR-G UARD.

SPECIFICATION forming part of Letters Patent No. 550,069, dated November 19,1895. Application filed October 6, 1894;. Serial No. 525,057- (No model.)

To all whom it may concern! 7 Be it known that I, TIMOTHY A. DEVANE, of the city of Troy, county of Rensselaer, and State of New York, have invented a new and useful Improvement in Oar-Guards, of which the following is a specification.

My invention relates to that class of devices which are attached to the front ends of motor-cars and used to prevent persons fallin g in front of them from being run over by the cars; and my invention has for its object the rendering of this class of devices more efficient and to better adapt them to the uses for which they are designed.

Acoompanyin g this specification to forma part of it there are two plates of drawings containing four figures illustrating my invention, with the same designation of parts by letter reference used in all of them.

Of the illustrations, Figure 1 shows my invention as applied to the front end of a car with the apparatus down and in a position for use. Fig. 2 shows it as applied to a mo tor-car and as drawn up and out of position at the end of a car. Fig. 3 shows in perspective the apparatus illustrated as detached from the car.

The several parts of the apparatus thus illustrated are designated by letter reference, and the function of the parts is described as follows.

The letter B designates the front sill of the car, 0 the front sill of the platform P, and B one of the car side beams.

' The letters T T designate side bars, of which there is one at each side of the car-bottom, each of which bars has a horizontal track part 25 and vertical end parts 25 15 with the upper ends of the latter attached to the car-bottom; and by means of which the side bars T are depending therefrom, with its side bar parts parallel to the car sides.

The letter S designates a slide-block, of which there .is one used in connection with each of the side bars T, and each of these slide-blocks is provided with tracking-wheels \V, which have grooved perimeters, and these tracking-wheels are each hung in cars c and therein provided with bearings W, in which to journal and to run upon the upper side of the tracking-bars or side bars T T.

The letter D designates the guard proper, which preferably consists of a cloth or wirescreen apron, secured to the frame F at its sides and outer end 6 and this frame is jogged at each side at J, so as to extend downwardly, and back of where thus jogged, at each of its sides f this frame F connects with one of the slide-blocks S at f by means of the pivot p The letter m designates a spring, which at its rear end rigidly connects with one of the slide-blocks, and which spring in each in stance of its use from where thus rigidly connected is extended frontwardly to rest on top of one of the side bars T, so as to force clownwardly the outer end of the frame F and its guard when frontwardly-projected beyond the car-bottom.

The letter S designates a spiral spring encircling each'of the side bars T between its slide-block S and its rear vertical end part 75 so that when the frame F is moved rearwardly it is so actuated against the force of the springs S The letter D designates a detaining and tripping dog, which is pivoted at d to the V-form depending leg U between its sides '0 v said leg being attached at its upper ends to the under surface of the car-bottom. This dog has a hook-form engaging end (P and a lever 61 at its inner end, and at the latter is connected to a vertical tripping-bar (1 the latter passing up through the car-platform and made with a head h, where it can be pressed down by the motorneers foot.

The letter S designates a spring connecting with the lever end of the dog and the under side of the car-platform.

The letter I designates a shoe-form spring that is projected from the outer end of the guard proper at each side, so as to pass down under the front edge of the latter, and the function of this spring is to engage with the ground when the guard is suddenly forced into position of use and thus prevent. the guard from abutting against any projection in the pavement.

The letter A designates a depending support on which the guard and its frame rest when in use, and this support has a horizontal part (E, on which the frame rests, and depending arms a, which at their upper ends connect with the under side of the car-platform.

As thus made, when the guard is not in use it is moved rearwardly and hooked onto the dog D with the parts in the position shown at Fig. 2. \Vhen aperson falls in front of the moving car or is likely to be struck by it, the motorneer presses down with his foot the tripping-bar d, which instantly releases the engagement between the dog and the frame F, rendering active the springs S and m,wl 1ich instantly force outwardly and downwardly the frame F and its guard to rest on the support A, and whereby the guard is in aposition at its outer end so near the ground as to interpose between the person in danger and the car-wheels.

In ordinary use the guard is in the position shown at Fig. 2, where it is out of the way, and when tripped for emergent useitis in the position as shown at Fig. 1.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combinatioiiwith the depending sidebars T, T, of the slide-blocks S, S, each having tracking rollers \V, mounted in ears 6, and adapted to run upon one of said side-bars; the springs S, S, of which there is one oneirclin g each of said. side-bars back of its slide block; the frame F, pivoted at each of its rear ends to oneof said slide-blocks and projected downwardly as extended forwardly; said. frame being provided with an apron I), and shoe-form spring I; and the depending sup port A, on which said frame may rest when projected forwardly,substantially in the mannor as and for the purposes set forth.

2. The com binationwith the depending sidebars T, T, of the slide-blocks S, S, each provided with tracking rollers \V, and mounted to run on one of said side-bars; the frame F, pivotally connecting at each of itsinner ends with one of said slide-blocks and therefrom extended downwardly and forwardly and provided with an apron D, and the spring on, connected rigidly at its inner end with each of said slide-blocks, with its outer free end bearing upon the top of each of said sidebars; and the depending support A, on which the frame and guard may rest when projected forwardly, substantially in the manner as and for the purposes set forth.

The combination with the frame F, pro vided with the guard or apron I), and constructed to be projected forwardly and downwa-rdly by the springs S, S, and m, and the slide blocks S, S, tracking on the side-bars T, T, substantially as described 01 the dog I pivoted at (F, to a hanger U, and having a hooleform end (Z and provided at its lever end with a trippingbar (l constructed and arranged to be operated substantially in the manner as and for the purposes set forth.

Signed at the city of Troy this 5th day of September, 1894-, in the presence of the witnesses whose names are hereto written.
