sArETY-GUARD FOR ELEVATORS.

" SPECIFICATION forming part of Letters Patent No.

` `Y` l Application filed Marcll 14, 1883. (No model.) l

5 Guards for the Shaftsof Elevators, of which i the following is a specification.

. My invention relates to that class of' eleva` tor` safety-guards which are made of flexible "material and are attached at one end tothe i 1o elevator-car, so as to move therewith and cover l the door-openings above and below the car;` and it consists in the improved construction p and arrangement of the tlexible safetyguard and'its attachments, as hereinafter fully set i5 forth."`

p Figure l is a front elevation of the elevatorf "l shaf y. Fig. 2 is a central vertical section ta-` y ken in the line e z ofFig. l. Fig. 3 is a ver-` p tical section taken in the line w w of Fig. l.` zo Fig. 4 is a transverse section taken in the linel Figsg, 6, 7, `and 8 a-re `detail .fr a: of' Fig. l.

tachedthe safety-guard F, formed of a flexig ble canvas apron, j', upon the front surface of' gowhich, at suitable intervals, are placed the a transverse bars g g, which serve to support` p and stiften the apron transversely without in` a p terfering with its longitudinal flexibility. To

\ the lower front corner of the car B is attached f ;l the flexible canvass `apron f', also having attached to its `front surface the transverse bars ,r/ y, and the oppositeedges of the aprons f f' are made to pass up and down within the` groove e of the guides G G, which are arranged `4o vertically in the elevator-shaft at each side of the door-openings H H, as shown in the trans` verse section, Fig. 4. At the upper and lower p l ends o`f the groovedguides G G, for the pas- `sage ,of the safety-guard F, are placed the `guiding-rolls I I', which serve to direct the f safetyguard into the groove of the guides G G,

Oto follow the movement of' the car either in guard into the guiding-grooves e e.

`in order to secure ready access to the interior rising or falling, and the rollslfl' thus allow `the safety-guard to be deflected, as required,`

at the ends of the elevatorshaft without Obstructing the free and `direct entrance of the Above the guide-roll, Figs. 2 and 3, is placed the roll J, for Winding up theapron f, or that portion of the safety4guard F which lies above the car B, and the roll J is actuated to wind up the apron f by means of the rope K and weight L, the rope K becoming wound up on the roll J when the car B descends in the shaft, and unwinding from the same when the car takes an ascending movement. Below the guide-roll I', Figs. 2 and 3, at the lower end ofthe shaft, is placedthe roll J', for winding up that portionl of the safety-guard F that lies below the car B; and the roll Jis actuated in' its windingup movement by means of the rope K', which passes from the roll J' under the pulley M, thence to the top of the shaft and over the pulley N, and downward to the weight L', the rope K' becoming wound up on the roll J" when the car ascends in the shaft, and unwinding from the same when the car takes adescend ing movement.

The bars g g, attached to the apron f, may be made of wood, and provided with a central groove, 7L, into which is placed a metallic bar or sheet-metal strip, t', edgewise, as shown in the transverse section of the bar, Fig. 8, and in the vertical view and partial section, Fig,` 7, the bar g being attached to the canvas apron f by means of screws j j or by suitable cement. The apron f may be divided longitudinally at the lines 7c k, and transversely on the line m m both above and below the car B,

of the elevator-shaft by moving the flap a in-` ward, as shown in Fig. 6; and when in its closed condition the angularly-divided bars g g are secured to each other by means of suitable pins, o, Fig. 8, which enter the holes 9o p 19,'shown in Fig. 7, thus locking the parts again firmly to each other. The safety-guard F may be lettered and notated, as shown in Figi 1, in order to indicate the position of' the car in the shaft at each of the. several floors, and uponA the arrival of thear4V atany o ne of the doors of the shaft'A, the position of the car at that moment will be indicated at the doors of each of the other iloors, Whether above or below.

I do not of course limit my claim to the specific lettering and notation shown in the drawings, Fig. Al, but include any form of marking, lettering, or notation which, when printed, stamped, marked, or attached to the safety-guard F, will serve to convey the desired information regarding the position ofthe car. y

I claim4 as my inventionl. The combinationof the apron j', provided with the transverse bars ,r/ r/, Withthe elevator-car B, the grooved guides G G at opposite sides vof the door-openings, roll J, adapted for rolling up the apron j', the intermediate guide-roll, I, adapted to guide the apronf into the grooves of the guides G G from the rolledup portion of the apron upon the roll J, rope K, and Weight L, substantially as described.

2. The combination of" the elevator-car B,

the grooved side guides, GG, apron f', pro- @sasso vided with the transverse bars g' g, roll J', adapted for rolling up the apron f", guideroll I', adapted to guide the apron f into the grooves of the guides G G from the rolled-up portion of the apron upon the roll J', rope K', pulleys M and N, and Weight L', substantially as described.

The combination of the elevator-car with the safety-guard, provided with a swinging door, formed from the material of the safetyguard, and moving with the car, substantially as described. 1

4. In a safety-guard for t-he shaft of an ele.- vator, the transversely-arranged Wooden bars, provided with the metallic strengtheningpiece arranged edgeWise in the wooden bar, substantially as described.

5. The safety-guard, arranged to move up and down with the movement of the elevatorear, and vmarked or notated 'to indicate the position ofthe elevator-car in the shaft, substantially as described.
