SAFETY-GUARD FOR OPEN CARS.

srnornrcnfrron' forming par. of Lea-ers ment No. 517,339, dated Merch 27,1894. Application led December 13, 1893. Serial No. 493,552. (No model.)

.T OLZ'Z whom it may concern:

yB eit known that I, WILLIAM HENRY HART, a citizen of the United States of America, re-

siding at Chelsea, in the county of Suffolk, in

the State of Massachusetts, have invented certaln new and useful Improvements in SafetyvGruards for Open Street-Cars, of which the :therein referred to is the side next the adjacent track on which cars move in the opposite direction; and when a car is switched from'one track to the other at the end of the route or other point where its course is reversed, the position of the car in its relation to thev adjacent track is changed, and what was formerly the .safe side becomes the danp ger side, andthe side formerly dangerous be` comes safe.

The objects of this invention are to provide safety guards for opposite sides of the car, which will not disflgure its appearance, and which can be readily shifted with slight effort and without annoyance to the passengers remaining in the car, into open position on the outer or safe side of the car and into closed position ou the inner or dangerous side thereof.

The invention embraces two guards or gates extending longitudinally of the car on opposite sides thereof and suspended from opposite ends of transverse flexible supports which pass over pulleys in the roof or upper part of the car in such a manner that when either gate is down, closing the several passage ways at one side of the car, the other gate is up, leaving open the opposite ends of the passage ways on the other side of the car; the shifting of one involving the simultaneous shiftingof the other. The gates are preferably of collapsible structure so as to fold into compact form when in raised open position and means are preferably provided for locking each in closed position.

Figure 1 of the accompanying drawings represents a side elevation of an open street car provided with these improved safety guards. Fig. 2 represents a transverse section thereof on line 2-2 of Fig. 1. Fig. 3 represents an enlarged transverse section on line 3-=-3 of the guards Fig. l of one of the collapsible guards in connection with a fragment of one of the side posts of the car, said guard being in down or closed position. Fig. 4 represents an enlarged transverse section of a fragment of the car body on line 4-4 of Fig. 1 and of the same guard in a collapsed and open position. Fig. 5 represents an enlarged side elevation of a fragment of one of the collapsing guards,

' portions of the upper rail being broken out.

Fig. 6 represents an enlarged transverse section on line 6-6vof Fig. 5 of the collapsing guard and a fragment of the dash-board provided with a guide for receiving one end of the guard. Fig. 7 represents a horizontal section on line 7-7 of Fig. 6 of the dash-board and lower rail of the guard in the guide way attached Vto said Adash-board. Fig. 8 represents a side elevation of a fragment of one of in the form of a non-collapsible gate. Fig. 9 represents a transverse section of the guard illustrated in Fig. 8.

The same reference numbers indicate the same parts in all the figures.

The open summer street caris usually constructed with a number of facing or reversible transverse seats as 10 alternating with transverse passages, as 11, said passages being open at their opposite ends on both sides of the car, and with platform steps 12 and 13 suspended from the side sills of the car body and extending longitudinally thereof, serving as means of ingress and egress to and from the passages between the seats.

In this invention two vertically movable guards or gates, as 2O and 30, are suspended on opposite sides of the car from opposite ends of flexible supports, as 40, 4.1, and 42, each of which passes over suitable guides, as 50, 5l and 52, disposed in the upperlpart or roof of the car. erably of such length as to close all the passages 11 on one side of the car and the flexible supports 40, 4.1 and 42 are of such length that when a guard of one side is down in closed position, the lguard of the other side is raised in open position. The weight of one guard counterbalances that of the other and when one guard is moved up the other descends of its own weight, it being only necessary to overcome the friction of the supports to effect the simultaneous shifting of Each guard or gate is prefboth guards. The flexible supports are preferably in the form of chains and the guides are preferably in the form of sprocket wheels or pulleys.

Suitable ways are provided on which the gates may slide. For this purpose the cai herein shown is provided at each side with two or more vertical rods, as (iO, preferably disposed opposite the side posts lt. These rods extend from a point at or near the roof of the carto points opposite the seats thereof. Their upper ends may rest in sockets in the purlins and their lower ends may be bent at right angles and passed through the posts 14, in which case nuts, as 6l, and washers as 62, may serve as fastening devices. Any other suitable attaching or fastenin means may be employed. There may be as many rods as there are side posts or a less number as desired. These rods are preferably composed of brass, bronze or any other iinoxidizable metal, and they preferably stand out from the posts a suiicient distance to admit the hand between them and the posts, whereby they are adapted to serve as handles to be grasped by the passengers on entering. The

gates

20 and 30 are adapted to move up or down on the ways or rods by any suitable means, a convenient means being hereinafter described.

Locks are preferably provided for holding the gates in closed position when lowered. These locks are preferably automatic in their action and may be in the form of spring catches, such as 70, disposed at the side posts or other convenient points, preferably near the ends of the car, where they areeasily ac cessible to the driver and conductor. These -catches are set in slots formed in the posts or in boxes attached thereto and latch over the gates when lowered. These catches are provided with knobs, as 7l, by which they may be released when the gate is tobe opened. These guards as 2O and 30 may be in the forni of bars, or ornamental structures as indicated in Fig. 8;. but they are preferably in the form of a folding or collapsible gate so that each When in raised position occnpiesa small space in the top of the car and constitutes a wide gatewhen in closed position.

The-collapsible gates illustrated in Figs. 1, 2, 3, .tand 5 are each composed of three bars, a top bar 2l, a bottom bar 22, and an intermediate bar 23. The intermediate bar is provided with longitudinal slots, as 23', disposed at intervals along its length. Links 2t and 25 are pivoted to the top baraiid diverge in opposite directions therefrom when the gate is in open position, and links 26 and 27 are pivoted to the bottom bar and extend upward therefrom at angles of opposite inclination. The links 24; of the top bar are united at their lower ends with the upper ends of the links 2G of the bottom bar by means of pivot pins 28 which pass through and slide in the slots 23', and the links 27 of the bottom bar are connected at their upper ends with the lower ends of the links 25 of the top bar by means of pivot pins 29 which pass through and slide in the saine slots 23. The links of the top bar are preferably double as shown. This connection of the bars enables them to fold and expand in a sort of lazy-tongs movement. The bars ai'e preferably constructed of sheet metal and the top bar 21 is preferably hollow, whereby it isadapted to receive the intermediate and bottom bais when the gate is folded or collapsed, as illustrated in Fig. 4. The ends of the flexible su pports 40 are connected with the lower bar so as to effect the folding of the gate when lifted. The top and bottom bars are provided with perforated lugs. or straps 3l and 32 which encircle the guide ways or rods 60 and cause the gate to slidcon said rods. Stops 33 are attached to the side posts on opposite sides of the ear near the ends thereof and serve toarrest the top=bar of either gate when lowered. I

The ends of the gates may or may not be adapted to engage the `dash-board in some manner. Such engagement is not necessary but may be done if desirable. A convenient means of effecting this connection is illustrated in Figs. 5, G and 7.

The dash-board, as 80,is provided at its op posite ends on its inner face withl a vertical bar, as 8l, provided witha` guide Way 82, said guide way being flared atits upper end and adapted to receive the lower body portion of the topbar 21 of the gate, and the lower portions of the guide way being adapted to re- .ceive the endsof the intermediate and bottoini bars. The ends of these latter bars may be provided with L-shaped hooks 83 which eugage an undercut recess 84 inisaid'` guidcway as shown in Figs and 7. The daring of the upper end of the guide way facilitates the entr i of the gate thereinto.

In the use of this safety guard for street cars, the gate of one side is inxraised open position while the gate of the opposite side is in lowered oi' closed position. The

gates

20 and 30 being in the respective positions-shown in Fig. 2,.in which the formeris in'open andthe latter in closed position, and it being desired to reverse the positions of the gates owing to the change'of direction of the car, the locks asV 70, at the opposite ends of the gate 30are released by the conductor and driver respect ively, and said gate is raised by them.` This lraising of the gate 30 causes the descent by gravity of the gate 20 on the oppositeside` of the car, and the upward movement of one andthe descent of the other continue until the gate 2O closes the passage` ways at its side of the car and is engaged and locked by the automatic locks on that side: When the top bar of the gate 3() reaches the upper end of the guide rod GO it coinesiii contact. with the roof of the car, and the bottom bar continues to move upward and causes the collapsing or folding of the gate, the intel'- mediate and bottom bars being raised into the hollow top bar, whereby the closed gate IOO IIO
