SPECIFICATION forming part of Letters Patent No. 559,318, dated April 28, 1896. Application tiled November 25, 1895. Serial No. 570,011. (No model.)

To all whom, t may concern.-

Be it known that I, IVILLIAM E. BATCHEL DER, residing at Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented a new and useful Improvement in Safety-Gates, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to a new and improved safetygate for railroads and other crossings; and it consists of the novel features of construction and relative arrangement of parts hereinafter fully described in the speci- Iication, clearly illustrated in the drawings, and particularly pointed out in the claims.

The object of the present invention is to provide a device of the above class which shall be simple in construction, easy of operation, and the working parts of which are protected as far as practicable from injury from dust or water.

The present invention is illustrated in the accompanying drawings, in which- Figure l represents a top plan view of a portion of a railroad and my improved safetygate. Fig. 2 is a longitudinal vertical section on line 2 2, Fig. I, showing the gate in its raised position. Fig. 3 is an enlarged view, partially in section and partially in side elevation, 'also showing the gate in its raised position. Fig. 4 is a transverse vertical section on line 4 4t, Fig. 3. Fig. 5 is a detached view of a portion of mechanism for raising and lowering the gate. n

Similar letters of reference indicate similar parts throughout the several views.

In the drawings, a represents a conventional track or railroad having the planks a' placed between the rails a2 at the point used as a crossing. All these parts are of the ordinary construction.

My improved safety-gate b may conveniently be arranged parallel with the track and in any desired proximity thereto.

My improved gate b' is made up of a series of vertical supports b b' b' b, Jac., which are connected by the rail b2. V

In the form of my invention shown in the drawings I have secured to the rail b2, between the supports b and b', a series of vertical rods b3 b3 b3, dac., which may be rigidly secured to the rail b2 or dependent'loosely therefrom.

In connection with my improved gate I have provided an inclosed subway or conduit c, the upper covering of which is `preferably flush, or nearly so, with the surface of the street. The conduit c may be of any suitable form or construct-ion for the purposes hereinafter set forth. In practice I prefer to construct the same of a bottom plate c and side plates c2 c2, made integral or rigidly bolted together. (See Fig. 4.) The plates c2 c2 are conveniently provided along their upper edges with the flanges c3 c3, to which is secured by bolts (not shown) or other suitable meansaremovable cover c4. Below the subway or conduit c are located a series of tubular uprights d cl d d, dac. which project into the conduit c and are held in position below the same by being embeded in the ground or other suitable means.

The aperture through which each of the tubular uprights enters the conduit c is preferably fitted to thek upright and sealed around the same with solder, lead, or any suitable sealing means, or a water-tight connection formed by any of the usual devices. The tubular uprights d may be of any form in section. In practice, however, for the salte of economy, I have used the commercial forms of piping. The bore of each of the uprights CZ is of greater diameter than that of the support b, which is received thereby, as hereinafter described. The portion of each of the uprights CZ which is projected into the conduit c receives a tubular lug cl', which is in` serted therein and preferably fitted thereto, and which is made integral with or suitably secured to the removable cover c4. The support b is fitted to thebore of the lug d', through which it is projected into the tubular upright d. The support b is conveniently provided at or near its lower end with a collar or ferrule b4, which is fitted to the bore of the upright d. The above-described arrangement is such that each of the supports D is free to reciprocate in the upright d, being guided and held in position by the collar b4 and the lug d'. In the form of my invention shown in the drawings I have provided for cach of the rods b3 an upright d3, which is projected into the conduit c and receives a lug dL on the cover c1', the arrangement, as shown, being substantially the same as that of the uprigh 's d d, the., and supports Z1' U, the., heretofore described.

To prevent any possible accumulation of water in the uprights d d 1, the., and d3 di* (73, &c in the form of my invention shown in the drawings, I have connected each of the uprights d and L3 with a pipe or line of pipes d5, which is inclined toward an outlet d, which communicates with a sewer or other suitable place of emptyin The pipe d5 may, if desired, be provided with a flushing-pipe Z7 and an inclined cleaning-pipe d8, through which a iiexible cleaner may be inserted into the pipe di".

My improved gate may be raised and lowered by any suitable mechanism. The device shown in the drawings for that purpose is described as follows:

The reference-letter c represents a cable secured at one end to the rail b2, adjacent to the support b', nearest the end of the gate and extending over a suitable shcave e' into the conduit c and along said conduit c to a drum c2, adjacent to the opposite end of the conduit o. The cable c is wrapped around the drum e2 in the the usual manner and extends back along the conduit c, and thence over a suitable sheave c3 into the tubular upright d, its free end being attached to the collar or ferrule D". It may be said in this connection that the relative diameter of the support b and the bore of the upright d is such that sufficient space is left for the cable ebetween the support b and the walls of upright d. At each of the other supports 'o' D' U, duc., the portion of cable c connecting the rail b2 and the drum c2, as hereinbefore described, is provided with a shunt or branch c5, which extends upward over a suitable sheave c6 and is secured to the rail 1:2, adjacent to the support b At cach of the other supports b/b, the., that portion of the cable e connecting the collarl/l with the drum c2 is provided with a shunt or branch c7, which passes over a sheave cs into the upright d, in which it is secured to the collar or ferrule Z1" on said other support 1) in a manner substantially as heretofore described in connection with the description of connections of the main cable.

The drum e2 may be actuated by any suitable means, conveniently by a sprocket-wheel 6o j", suitably mounted in a casingf at a convenient height above the street to be actuated by a crank n or other suitable means and connected by a chain f2 with a sprocket-wheel e9, rotating with the drum c2.

In practice I have provided a counterweight h, suspended in a suitable well 7b', upon a shunt h2 from that portion of cable e connecting the collars or ferrules b4 with the drum c2. The shunt h2 passes over a suitable sheave h3 at or near the top of the well 7b.

The above-described arrangement is such that a rotation of the drum e2 in one direction takes up the portion of the cable c connecting it with the ferrules or collars b and correspondingly lets out that portion of the cable connecting it with the rail b2, thereby raising the gate b. A reverse movement of the drum e2 produces a reverse movement of the cable e and closes the gate l).

As shown in the drawings, the rail b2, when the gate Z) is down, rests upon the cover c4, and to prevent the accumulation of snow and ice on or about the rail b2, I have provided the steam-pipes L 7.5, extending along the sides of the conduit c and shielded by the gutters Z Z, which drain through the pipes Z Z into the pipe d".

It is to be noted in connection with the counter-weight 7L that it is connected with the ferrulcs or collars t* upon the several supports b' by the cable and the shunt connections therefrom. In order that the weight may act simultaneously upon all the supports b', I have provided in the shunts or branches from the cable a turnbuckle j), by means of which the length of the shunt or branch which connects the weight with the respective support may be adjusted so that the weight will act simultaneously upon the supports. I consider this a feature of importance in my present construction, as I secure thereby the simultaneous action of the weights upon all the supports and dispense with a plurality of weight-wells, utilizing the same counterweight for all the supports.

The operation of my invention has been sufficiently described in connection with the foregoing description of the form and arrangement of the several parts.

The advantages of my improved construction would seem to be self-evident to a person skilled in the art. I may, however, state in this connection that by dispensing with the opengate well heretofore found in devices of this class I greatly lessen the cost of construction, besides removing numerous objections thereto. Attention is also called to the improved system of drainage and the protection of the working parts from dust and water as provided for in the devices hereinbefore described. I would further state that I do not consider my invention as limited to the speciic construction hcreinbefore described; but

I claim as novel and desire to secure by Iletters Patentl. In a safety-gate the combination of a series of vcrtically-reciprocatin g supports, a rail connecting said supports, a series of tubular uprights adapted to receive said supports, a drainage-pipe and water-tight connections between the uprights and drainage-pipe, substantially as described.
