SAFETY-GATE FOR CAR-PLATFORMS.

SPECIFICATION forming part of Letters Patent No. 289,726, dated December 4, 1883,

Application filed October 18, 1883.

To all whom it may concern:

Be it known that I, EDWIN L. TEVIS, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in SafetyGates for Railroad- Car Platforms, of which the following is a specification.

My invention relates to improvements in the construction of safet gates for the platform and platform-steps of a railway-car; and the main object of my improvements, which are fully described hereinafter, is to so construct and so place a gate that when raised it will present a proper safety-guard, and when de- I 5 pressed will be entirely out of the way, so as to present no obstacle to free access to and eXit from the car.

In the accompanying drawings, Figure l is a perspective view of part of the end of a car,

showing the guard in an elevated position; Fig. 2, the same, showing the guard depressed; Fig. 3, a front view of the guard, with mechanism which may be used for operating the same; Fig. 4, a section on the line 1 2, Fig. 3;

and Fig. 5, a diagram illustrating the manner of arranging the guard.

The guard or gate, which will be best understood by reference to Fig. 3, consists of the base A, preferably composed of two bars of 0 wrought-iron secured together in such a manner that there shall be a space between them, two vertical guide-rods, D D, the top rail, B, arranged to slide on the said guides, and two sets, E E, of levers, constructed in the well- 5 known lazy-tongs fashion, for connecting the base A to the sliding rail 13, the lowest pair, a a, of each set of lazy-tongs levers being pivoted by a pin, w, to the base A, and the highest pairof each set being connected by links 0 e e to an attachment on the under side of the rail B.

It may be remarked here that, although I have shown two sets of lazy-tongs connections, there maybe but one set or more than two sets.

In applying this guard or gate I remove that portion, w, of the platform at each edge of the same which overhangs the riser y, as shown in Fig. 5, and the guard is so adjusted to the front'of the riser that the rail B of the guard will, when depressed, be in the position occupied by the said projecting portion 10 of the (No model.)

platform prior to its removal, so that the depressed guard cannot interfere with free egress from and free access to the car.

The base-bar A is secured to the steps of the car in any suitable manner, and the lower ends of the guide-rods D D are preferably secured to the base-bar, the upper end of the guide-rod D being attached to the usual guard-rail 0f the platform, and the upper end of the guide-rod D to the end of the car.

Different devices for raising and lowering the guard may be adopted. In the present in stance the lowest pair of levers of one set are connected by links m m to one end of a bar,

M, the opposite end of which. is connected to the lowest pair of the other set of levers by similar links. A short shaft, H, is arranged to bear in a hanger, t, on the under side of the platform, and an arm, n, on this shaft is connected by a link, 19, to the bar M, an operatinglever, I, also secured to the shaft, passing upward through a slot in the platform, When the guard is depressed, the operating-lever is in an out-of-the-way position against the usual 7 5 guard-rail; but when the guard is elevated the lever occupies the inclined position shown in Fig. 3, where it may be temporarily held by any suitable retainer, so as to maintain the guard in an elevated position.

It will be seen that there is a slot in the step w adjoining the riser y, Fig. 5, for admitting and permitting the free movement of portions of the lowest of the two sets of levers, the links m and bar M being below this step.

The guard or gate may be placed on the inner side of the riser 11 Fig. 5, in which case the platform will be slotted for the passage of the guard, the top of the rail B of the latter, when depressed, being level with the top of the platform. I, however, prefer to arrange the guard in front of the riser, in which case, however, a suitable cover-platesuch, for instance, as shown by dotted lines in Fig. 4
