LIFE-GUARD FOR STREET-CARS.

SPECIFICATION forming part of Letters Patent No. 558,659, dated April 21, 1896. Application filed November 4,1895. Serial No. 567,804. (No modelfl To all whom it may concern.-

Be it known that I, GEORGE A. PARMEN- TER, a citizen of the United States, residing at Cambridge, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Life-Guards for Street-Cars, of which the following is aspecification.

My invention belongs to that class of lifeguards generally known as front fenders; and it consists of a spring or yielding structure anda combination of parts by which it can be dropped onto the track at the will of the motorman, so as to pass under an object lying upon the road-bed.

In the accompanying drawings, Figure l is a side view of my invention attached to the platform of a car, which is shown partly in section. Fig. 2 is a front view of a portion of the invention with some of the parts shown in section. Fig. 3 is a plan view of Fig. 2 as it would appear with the platform of the car removed.

A is the platform of a street-car and B the dashboard.

O G are elliptic springs to the lower ends of which is attached the shelf or scoop, being a frame covered with a screen or netting suitable to support a person and to prevent his leg or arm passing through it.

The front edge of the scoop]) is suspended by chains or cords E from the loops or eyes F in the upper ends of the springs O, extending to the eyes G in the frame of the scoop.

Bolted to the under side of the platform are the hangers II II, in which is journaled.

the crank-shaft I, the ends of which extend outwardlybeyond the journals and are made to fit square holes J in the blocks K, made in two parts, between which the springs C are clamped, the parts being held together by the bolts It.

To the crank-shaft I are secured the horizontal arms L L, extending backwardly and engaging the lugs or trippers Z Z, secured to the rock-shaft M, which is journaled in bearings m m on hangers P, secured to the under side of the car. w I

To the upper side of the rock-shaft M is sccured the arm 0, which is normally pulled backward by the spring 19. S is a lever which extends through the platform of the car to about the level of the knee and has a broad and fiat top against which the knee of the motorman can be conveniently pressed. The lever S is pivoted to the hanger U, secured to the bottom of the car, and by means of the lever S, link T, and arm 0 the crankshaft is oscillated and the trippers Zlare withdrawn from contact with the arms LL, which latter are allowed to rise, and thereby the front end of the scoop drops to the ground into a position to slide under a person or other object lying upon the track.

The plain lines of the lever S, link T, arm 0, and other parts show their positions when the fender is in its ordinary and normal position, at which time a person standing upon the track would be struck and caught in the fender. The dotted lines show the positions of those parts when the fender is dropped so as to catch a body which has fallen upon the ground. The yielding feature of the device is of the utmost importance in either case, to avoid shocks to the car and breaking of the fender, to ride over the irregularities of the ground, and to make the fender hug closely to the surface of the road-bed.

NVhen the fender is not in use, it may be turned up against the dashboard of the car and secured by a hook or other suitable means.

I am aware that front fenders have been attached to cars by means of springs, but

were not so arranged that they could be dropped, and also that front fenders have been made which could be dropped by the motorman, but which were rigidly secured to the car. In my invention the construction of the springs and their means of attachment to the car differ from those in any fenders heretofore devised, and the combination of parts by which the fender is dropped differs from any prior mechanism for that purpose, whereby I am able to combine in one machine the features of a spring or yielding attachment to the car and a dropping device. It will also be noticed that my fender is not in any manner attached to the dashboard, but is supported wholly by the body of the car, which is a feature of great practical value.

What I have invented, and desire to secure by Letters Patent, is

The combination of the scoop D, two elliptical springs O, C, secured in a vertical position, and having their upper and lower ends free to yield, said scoop being pivoted to the lower ends of said springs, the blocks K, K,

5 secured to said springs O, (J, and fixed to the crank-shaft I, the crank-shaft I, journaled in the hangers H, H, one or more horizontal arms L, rigidly secured to the crank-shaft I, and exten din g backwardly, the rock-shaft M,

IO having one ormore trippers Z, secured thereto and engaging the arm L, the arm 0, and lever S, connected by the link T, arranged as shown for releasing the arm L, substantially as described.
