upper portion of the tie, in order to permit ,and useful Improvements in Railway Crossl`ies, of which the following is a specification.

This invention relates to railway crossties, and has for its object to provide a strong, durable and thoroughly etiicieut device of this character, the. construction and relative disposition oi the several parts of which is such as positively,v to prevent the jar or impact of a train or car traveling' over the tie from cracking', breaking or otherwise injuring; the salue.

A further object of the invention is to provide a cross tie formed of a plurality of sections the outer ends of which are deflected upwardly to permit a slight tipping,F or rocking movement thereof, there beinga coiled springl interposed between the abutting ends ot the same to prevent injury thereto.

A further object is to form the cross tie with depeinling` anchoring members or lugs and t'urther to provide the abutting; faces of said tie sections with atongue and groove connect ion .so as to prevent binding or we( ,fring action between the parte.

A still further object ot'lthe invention is generally to improve this class of devices, so as to increase their utility, durability and general eti'iciency. 7

lt1 or a full understanding of the invention and the merits thereof and also' to acquire a knowledge ot' the details of construction and the means for effecting t-hc result, ref! erence is to bc had to the following description and accompanying drawings, in which;

Figure l is a perspective view of a railway cross tie constructed i1 accordance with my invention, Fig'. 9, is a. side elevation partly in section of die same, and Fig. il is a transverse sectional p view taken on the line 3-3 of Fig. 2. Y'

Corresponding and like parts are referred to in the following description' and indicated in all the views of the drawing by the same reference characters.

The improved cross tie forming the subject matter of the presentv invention cotilprises inating sections 5 and 6, preferably cement or other plastic material,

a slight rocking or tilting momment ot said sections incident to the ot' ears and other railway'rolling stock over the tie.

The tie sections are secured together by means of longitudinally disposed 8 the opposite ends of which are connected by transverse bolts 9 which also pierce the adjacent tie sections for engagement with nuts or similar fastening devices 10. The tie barsI Snot only forni a connection between the sections 5 and G but also serve to assist in reinforcing-and strengthening the latten The inner end of the tie section 5 formed with a curved socket il which. receive-,- a correspondingly shaped ton-gue lf2 fori'ned on the mating section t3, the lower'taces of the tie sections at their provided with depending members or lugs 13 adapted to be embedded in the road bed thereby to prevent longitudinal movement of the cross tie.

The abutting faces of the tie sections i and G at the anchoring members are termed with a plurality of sockets 1 4 in which are seated metallic tubesor casings 15, adapt to receive coiled springs 16, the latter being interposed between the lugs 'i3 oit the mating sections thereby to forni a yieldable cornice tion between the saine and thus assist in at sorbing any jar or impact of the tie scc-A tions incident to the passing of rolling` stock.

The upper face of each tie section Jformed with a transverse recess 17 undercut as indicated at 18, and adapted to receive a correspondingly shaped tie plat-e 19, there being; a recess formed in the cross tie and in communication with the recess 17 sov as to allow the tie plate 19 to be i ressed downn wardly within the recess 20 when subject to the weightI of a car.

The rails 21 are retained in position on the tie plates 19 by means of angularly dislposed plates or brackets 22 having ay series oi openings formed therein for the reception of bolts or similar fastening devices 24, which latter pierce the tie plates 19 and hold the rail rigidly combined therewith.

lt willhere be noted that by providing` the attaching brackets 22 withv a series of openings the rails 21 may be adjusted laterally on the tie plates 3.9 so as to properly ce Ater the on the cross ties, should the, ra i" eey-to spread. Thus it. seen that the springs 16 may serve to vi d ably support the tie sections in point of juncture beirug;`

(a ful position, while the plates 19 and recess 20 permit a slight yielding movement of the rails independent of the mating tie sections. It will also' be noted that the curvature of the walls of the socket 1l and tongue l2 is such as to prevent binding or wedgiiig of said sections when the outer ends thereof are tilted slightly by the weight of a train of cars traveling over the cross ties.

llVhile it is preferred to construct the cross ties from concrete it is obvious that the same may be formed of metal or other suitable material without depart-ing from the spirit ofy the invention. A

Having thus described the invention, what is claimed as new is;

l. A railway cross t-ie including relatively movable mating sections having inter-engaging ends and provided on their upper faces with means for engagement with a railway rail, and yieldable means interposed between the abutting ends of the tie sections.

2. A railway cross tie including relatively movable mating sections having their inner ends provided with a tongue and groove conneet-ion and their upper faces provided with means for engagement with a railway rail,`

and a spring interposed between the abutting ends of said tie sections.

3. A railway cross tie including relatively movable mating sections having their inner ends provided with a tongue and groove connection and their upper faces provided with means for engagement with a railway rail, anchoring lugs depending from the tie sections at the abutting ends thereof and adapted to be embedded in the ground, and a spring interposed between the lugs.

4. A railway cross tie including mating sections one of which is provided with a grooved socket and the other with a correspondingly shaped tongue adapted to enter said socket, bars secured to the opposite sides of the tie sect-ions and forming a connection between the same, lugs depeiiding from the sections at the abutting ends thereof, yieldable means interposed between the lugs, and means carried by the tie sections for engagement with a railway rail.

5. A railway cross tie including mating sections having their outer ends deflected up- 'wardly and their inner ends provided with inter-engaging parts, lugs depending from the tie sections at the meeting ends thereof,

and provided with registering sockets, springs interposed between the tie sections and seated in the sockets, and means carried by the tie sections for engagement with a railway rail.

6. A railway cross tie including mating sections having their inner ends connected to permit independent rocking movementof said sections and their upper faces provided with means for engagement with a railway rail, and yieldable means interposed between the abutting ends of the mating tie sections for norinall)y and "vieldably supporting the same in horizontaalineinent.

7. A railway cross tie including mating sections having their outer ends deflected up wardly and their inner ends formed with depending anchoring lugs having registering sockets formed therein, tubes seated in said sockets, tie bars secured to the opposite sides of the tie sections` and having their terminals connected by transverse bolts,^

coiled springs interposed between the abutting ends of the tie sections and seated iu the tubes, and means carried by the tie sections for engagement with a railway rail.

S. A railway cross tie including mating sections having independent rocking movement, and each having its upper face provided with a transverse. seat-'nig recess, a tie plate seated in the recess of each tie section and adapted to support a rail, and means for clamping the rail in engagement with the tie plates, there being a recess formed in each tie section below the adjacent tie plates.

9. A railway cross tie including mating sections having their upperfaces provided with seating recesses the s'ide walls of which are undercut, there being auxiliary recesses formed in each tie section and communicatu a ing with the adJaeent seating recess, resilient tie plates fitting within the seating recesses and adapted to support a railway rail, meansl for clamping the railway rails in engagement with the tie plates, and yieldable means interposed between the adjacent ends ofythe tie sections.

In testimony whereof I affix my signature in presence of two witnesses.
