RAIL-FITTING.

Specification of Letters Patent. Patented Egg 3(), 1919.

Application filed January 15, 1917. Serial No. 142,378.

To all whom it may concern:

Be it known that 1, WILLIAM B. Caren, a citizen of the United States, residing at New York city, county of Kings, and State of New York, have invented certain new and useful Improvements in Rail-Fittings, fully describedand represented in the following specification and theaccompanying drawings, forming a part of the same.

This invention relates to certain improve ments in rail fittings of thatclass in which rails are set up in position in posts or standards, as, for example, the guard rail constructions now widely employed in railway and subway construction. h I

It is the especial object of the present invention to provide an improved fitting for use in such constructions in which the rails and the standards or posts are locked together by a locking means which can be placed in the fitting after the rails are in position, and can be removed from the fitting while the rails are in position thereon,

so that if it benecessary for any; reason to V replace such locking. means, this can be done without disassembling the whole structure, and so that, furthermore, the locking means will'n'ot be displaced or lost when it is necessary to readjustor tighten the loekingineans after the structure has become settled by It is a further object of the invention to provide an lnprcved'fitting for this purpose which shall be simple, and therefore cheap in construction, and which'will be ef fective for long periods.

With these and otherobjects in view, a detailed description of the preferred constructions for effecting them, will be'given in connection with the accompanying drawings, in which Figure 1 is a cross-section of a two-rail high structure, showing the improved fittings, the rail pipes and supportlng post being broken away to save space;

Fig. 2 is an end view of the upper part of the construction shown in Fig; 1, and

Fig. 3 is an end view of the lower. part of the construction shown in Fig. 1, part of the standard or post being shown broken away.

7 Referring now to these drawings, constructions embodying the invention will embody a sleeve or other'siinilar tubular sup port through which the rail passes, such a sleeve being marked 1. In constructions embodying the invention, this sleeve will be provided with a projection by which the litting is attached in the structure. These attaching projections are marked 2, and in the preferred construction will be formed integrally with the sleeve 1. In the drawings is shown a sleeve having one attaching projection which is used for the upper ra'il, and a sleeve having the lower attaching projection 2 and an upper attaching projection 33, this latter sleeve being used for the middle or under-rails, where the rail structure is two or more rails high. The attaching projection 2 is threaded and has connected thereto a standard or post section 4: of pipe as is usual. The fitting employed for the iniddie or under-rails has the other end of the post or standard 4 threaded into the attaching projection 3, before referred to.

- suitable post support, not shown.

The rails which are, as usual, of iron pipe, are marked 6 and are inserted in the sleeves and locked in position by locking wedges cooperatingwitl: the sleeves and acting to lock the pipethereon. In accordance with the invention, these locking wedges are so shaped thatthe wedge locking key may be placed in position in the fitting and re moved therefrom while the rail is in place. The wedge keys are, furthermore, so shaped as to have a large bearing surface against the pipe, and the locking key and the attaching projections are formed to give a large bearing surface for the other side of the locking keys. While the constructions for effecting this may be somewhat varied, a preferred form of key isthat shown in Fig. 1, marked 7 this key 7 being provided with an end 1.2 having a wedge-shaped surface 13 and a long straight surface 14, a

stem 15 extending from the head 12 and dropped. downward slightly, as shown, and

ting, this construction permitting the bearing surface let to be very long, and thus result in a very strong and rigid structure, and permits the key to be positioned in the fitting and removed therefrom while the rails are in position. In the best constructions the inner wall of the projection 2 at the point where the bottom of slot 16 is made, is formed thicker than the rest of the wall, this being readily effected by casting a lug 19 at that point, this construction giving a substantial bearing surface at that point for the locking key. With a locking key as before described, the other side of the projection 2 opposite the slot, is provided with a hole 20 through which the threaded end of the key is passed. Suitable means; are provided for locking the keys in wedging position in the fitting and for taking up wear necessitated by settling of the structure or other reasons. These means may be of various characters. A convenient one is a nut 21. Where the locking means is a nut, this nut will be preferably of brass to prevent it from rusting fast to the stem, and will preferably be provided with a recess 22 for protecting a certain number of the threads at the threaded end of the key which can be used for tightening the wedge. In assembling structures embodying the invention, a certain number of the posts, such as 3, are set up at suitable spaces and the pipes inserted in the fittings and the rails and posts trued up to proper position. The locking keys are then put in place and tightened up to locking position. With the construction described, a very strong, rigid structure can be produced and one in which the locking keys can be inserted and removed while the rails are in place, so that it is not necessary to disassemble the structure, where it is necessary to put in new keys, if they by any chance become lost or wear out.

' While the invention has been shown and described in its preferred form, it will be understood that certain changes and variations maybe made in it without departing from the invention. It will be understood, furthermore, that the fitting is cap-able of use with structures other than railings oi the class referred to,and may be and is intended for use in other relations.

hat is claimed isi 1. In a rail fitting, the combination with a rail, of a sleeve through which the rail passes, a wedge locking key, means for positioning the key in the sleeve and removing it therefrom while the rail is in position in the sleeve, and means for operating the key to lock the rail in the sleeve.

In a rail fitting, the combination with a rail of a sleeve through which the rail passes, an attaching projection on the sleeve having a slot open at the top through the thickness of the sleeve and projection, the lower face of which is beveled, a wedge locking key formed to pass through the slot into the projection under the rail having a wedge face cooperating with the beveled face of the slot and a plain face taking against the rail, a stem on the key passing through an opening in the projection, and means cooperating with the stem for locking the key in the projection.

3. In a rail fitting, the'combination of a sleeve through whichthe rail passes, an attaching projection onthe sleeve having a slot extending through the wall of the sleeve and projection, the lower wall of the projection being beveled and formed with a thickened portion having a similar bevel to provide a wide bearing surface, a wedge locking key formed to pass through the slot having a wedge face cooperating with the beveled face of the slot and the thickened portion and a plain face taking against the rail, a stem on the key extending through an opening in the projection, and means on the stem for locking the key in position.

4:. In a rail fitting, the combination with a rail, of a sleeve through which the rail passes, a wedge locking key having a stern, an opening at one side of the sleeve through which the stem may be passed, a slot open at the top through the thickness of the sleeve at the opposite side of the sleeve said openings permitting the insertion and removal of the key when the rail is in position in the sleeve, and means for operating the key to lock the rail in the sleeve.

In testimony whereof, I have hereunto set my hand.

WILLIAM B. GATER.
