To all whom it may concern:

Be it known that I, JAMES F .`LoGAN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Self-Adjusting Platforms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of` reference marked thereon, which form a part of this specification.

This invention relates, generally, to improvements in station-platforms for railways; and, the present invention has reference, more particularly, to a novel platform which is adapted for use more particularly in the stations ofv subways and elevated rail` ways; and, which, in part, or as a whole, along the track is made with a self-adjust# ing element or elements adapted tol be actuated by the movement of an incoming train', and which operates to closeor bridgeover any undue space between the edges ofthe station-platform and the adjacentl edgel portions of the car-platform, in order to avoid or minimize the danger of accidents to persons getting on or off the train-platforms. l v` l 1 The present invention, therefore, has for its principal object to provide a novel and simply constructed self-adjusting platform which automatically adapts itself to the side of the trains, or the cars thereof, and is actuated by the incoming train or car, to practically provide a continuous platform or gangway between the platform, so as to cover or bridge overl any undue space between the respective platforms of the stopping car and the station, and especially so where the station-platform at which the trains stop is on a curve.

A further object of this invention is to provide a platform for railways in which the station-platform is provided with an automatically operating self-raising element or member which, at the time when there is no train in the stations, stands at a suitable angle along the edge of the platfo-rm, so as to be raised sufficiently above the Vhorizontal plane of the platform to Aprovide a guide which acts asa notice or warning to the persons standing` uponthe station-platform, while Waiting for a t ain, not to get too near to the edge of the platform.

. Other objects of this invention not at this time more particularly enumerated will be clearly understood from the following detailed description of my present invention.

l llVith the various objects of the present invention in view, the same consists, primarily, in a self-adjusting platform for the railway stations in subways or upon eleyjated railways; and, the invention consists, furthermore, inthe novel arrangements and combinations of the various devices and parts, as well. as in the details of the construction of the same, all of which will be more fully rdescribed in the following speciiication andl then finally embodied in the clauses of the claim which are appended to and which form an essential part of this specification.

The invention is clearly illustrated in the accompanying drawings, in which 1 Figure l is a plan view of a portionof a self-adjusting station-platform showing one embodiment o f the principles ofthe present invention; Fig. 2 is a transverse vertical section of the same, said section being taken on line 2-2 in said Fig. l, looking in the direction ofthe arrow a', and said view showing the various parts of the self-adjusting platform intheir normal initial positions when there is no train in the station; and Fig. 3 is afrontelevation, looking toward the platform in ,the direction of the arrow y in said Fig., l, Fig. 4 is a horizontal section of the several parts,. said section beingl taken on line -1-4 in 2. Fig. 5 is a transverse vertical section of the self-adjusting platform, said view vrepresenting the several parts in their adjusted positions when oper ated by an incoming train and standing in. thel station 4to discharge and take on passengers. Fig. 6 is a detail horizontal section taken on line 6 6 in Fig. 8; and Fig. 7 is a detail vertical section, vsaid section being taken on line 7 T in Fig. 4 of the drawings.

Similar characters of reference are employed in allof the above described views, to indicate corresponding parts. Referring now to the several figures of the drawings, .the reference-character l indicates a portion of a stationsplatform of any usual. and well-known construction as used in subway stations or on elevated railways, such platforms being usually made of concrete, although this is not essential. As shown in the accompanying drawings, in the present instance, the adjustable feature of the platform comprises a suitably constructed frame which may be made of any suitable material, and preferably of metal, the said frame being suitably aiiixed in a depression, as 2, with which the said platform is provided. The said frame consists, essentially, of a suitably formed base-plate 3, a rear wall 4, a front wall' and an intermediately extending wall 6, said walls being of different-heights, substantially as shown in Figs. 2, 4 and 5 of the drawings. The said walls 5 andG are also connected by means of side-walls 7 and S, substantially as shown, and all of said parts being preferably formed in one integral piece with the said base-plate 3. Suitably secured upon the upper edge of the rear wall 4, preferably by means of screws 9, is a forwardly extending plate 10, of substantially the same width as the width of the depression 2, the said plate 10 having its forward edge terminating above the upper edge of the wall 6, so as to leave a suitable space between said upper edge of the wall 6 and the lower surface of said plate 10, substantially as shown, and the purposes of which will be presently more fully specified. As shown, the said front edge-portion of the said plate 10 is suitably chamfered or thinned down upon its under surface, as at 11. The said frame is secured in its fixed position in the said depression 2 of the portion 1 of the platform by means of suitably formed anchor-bolts, as 12, which are embedded in the cement or concrete part of the platform, and the screw-threaded shanks of said bolts extending through the said base-plate 3 and being provided with .nuts 13 for preventing the displacement of said frame. It will be evident, however, that the said frame may be otherwise permanently secured in its fixed position. The said front wall is provided with suitably disposed holes 14, and the wall 6 is likewise formed with correspondingly located holes 15, each pair of

holes

14 and 15 providing suitable guides for the slidable arrangement therein of shafts or rods 17. The rear endportions of said shafts or rods are provided with screw-threads 18, and arranged upon each screw-thread 1S, so as to be located against'the face 19 of the wall 6 is a regulating nut 2O and a lock-nut 21. The opposite end-portions of the said shafts or rods 17 extend for some distance beyond the face 22 of the wall 5, extending into and being suitably secured, preferably by means of pins 23, to suitably formed receiving sockets 24, or other suitable fastening means, secured upon the rear face of a buHer-plate 25. This plate is vertically rounded or chamfered upon its face in two places, as at 26. The said plate 25 may also be provided with recessed portions 27 in which are arranged and suitably sccured, suitably formed boxes 28, each box being provided with a vertically disposed pin 29 upon which is arranged a roller or wheel 30.

Each wheel or roller has a portion extending from the open front of each box, substantially as represented in the several ligures of the drawings, the purpose of which will be clearly evident, and will be hereinafter more fully set forth. Each shaft or rod 17 is also provided with a coiled spring 31 which encircles that portion of each shaft or rod located between the rear face 32 of the buffer-plate 25 and the face 22 of the wall 5 for returning' the movable parts to their normal initial positions, after the buffer-plate has been operated by the train and then released in the manner to be presently described. Suitably secured upon the rear surface of the said buffer-plate 25, by means of suitable bolts or screws, as 33, or other suitable fastening devices, are suitably formed retaining devices or holders 34 in which are arranged and held suitably bent portions 36 of rearwardly extending operating rods or bars 35, each rod or bar being pivotally connected, preferably by means of the perforated end-portions or eyes 37, pins 38, and

brackets 39, with the rear and chamfered or tapered edge-portion 41 of a movable guardplate or similar element 40. The said edgeportion 41 of this plate 40, in its normal initial condition, is arranged in the open space formed between the upper edge of the wall 6 and the lower face of the plate 10, the chamfered or tapered portion of the guard-plate 40` being in engagement with the lower chamfered or tapered portion 11 of the previously mentioned plate 10, as clearly illustrated in Fig. 2 of the drawings. In its normal initial position, the said plate 10 is in the angularly raised position indicated in Figs. 1, 2 and 3 of the drawings, this raised condition of the plate 10 being caused by any suitably formed spring or springs, as 42, or other suitably constructed devices which will act in a manner similar to the spring or springs 42. The spring or springs 42 in this case have their end-portions 43 suitably con- .-nected with the rear of the buffer-plate 25 by means of screws or bolts 44, while their end-portions 45 are slidably connected with the said guard-plate or element 40 by means of a guide, as 46, so as to permit of the oscillatory or pivotal movements of said plate 40.

Having in the foregoing description in a general manner described the general construction of one form of self-adjusting platform for railway stations, especially in subways and upon elevated roads, I will now briefly set forth the manner of operating these devices and parts by means of an incoming train, so as to close any unusual space 0r gap left between the edge of the station-platform and the platforms with which the cars are provided.

It will be evident that the fixed part of the station-platform may be provided with any suitable number of the gap-closing devices or elements herein-above described, and that these devices may be of any desired widths; and, if desired, may even form the entire edge of the platform so as to insure the positive covering-over or closing of the space or gap between the station-platform and those of a car, when the train is at aV standstill in the station.

As a train enters the station, a portion of the one side of the moving train comes in slidable engagement with the buffer-plate 25, and with the rollers or wheels connected therewith, thereby forcing the buffer-plate, and the springcontrolled .shafts or rods connected therewith, in the direction of the arrow e in said Fig. 2. The result is that the plate 40, being connected with the bufferplate 25 by means of the rods or bars 35 attempts to move in the same direction, causing the chamfered or tapered edge-portion 4l to ride against the lower chamfered orl tapered edge-portion ll of the fixed plate 10, thereby causing the oscillatory or pivotal plate 40 to assume the lowered position clearly indicated in Fig. 5 of the drawings, and resulting in the closing or covering over of the space or gap ordinarily found be` tween the station-platform and the endplatforms of a car, and especially so where the station is placed upon a curve. As soon as the train moves out of the station, the car moves away from its active engagement with the buffer-plate 25 and the various springs will cause the several parts to once more assume their normal initial positions ready to be again actuated by the next incoming train.

While in the positions indicated in Figs. l, 2 and 3 of the drawings, the plate l0 being raised at an angle at the edge of the stationplatform, such raised position will serve as a guard or warning to the persons upon the platform not to stand too near the edge of the same.

Of course I am aware that changes may be made in the general arrangements and combinations of the' various devices and parts, as well as in the details of the construction of the same, without departing from the scope of my present invention as described in the foregoing specification and as defined in the claims which are appended to said specification. Hence I do not limit my present invention to the exact arrangements and combinations of the devices and parts as set forth in the Vsaid specification, nor do I confine myself to the exact details of the construction of the said parts as illustrated in the accompanying drawings.
