RAILWAY-TRACK.

T0 all whom tim/ay concern.'

Be it known that I, JOSEPH P.. MARois, of the city of Montreal, in the 'Province of Quebec and Dominion of Canada, haveinvented new and useful' VImprovements lin Railway-Tracks, and do hereby` declare that the following is a full, clear, and exact description. f

This invention relates to improvements in railway tracks, and the Objectis to provide means whereby a permanent foundation may be laid in the ground to which the rails may be attached easily and quickly.

The invention relates particularly to the laying of. street railway tracks, where Ithe In the drawings which illustrate this in-r ventionz-Figure 1 is a perspectiye view of the device as it would appear with all the pavement removed. Fig. 2 is a perspective viewV showing the bond between the sectionsy of the rail chair. Fig. 3 is a cross sectional view of a single rail, showing the method of embedding the same in the pavement. Fig. 4; is a fragmentary cross sectional view, 'showing a slight modification of the invention.

Referring more particularly to the drawings, 5 designates the ties which maybe ofwood, but are preferably of metal, `as the life and rigidity of metal is greater than that ofwood. Mounted on the ties Iare rail chairs 6 having attaching flanges 7, 'similar to the ordinaryrail base flanges. This rail Vchair is comparatively low and webless, the

head 8 rising directly from the flanges. The top of the head is flat and provided withy the central longitudinal groove 9. This groovel specifically does not forni one ofthe most importantv features of the invention, as it may be replaced by a rib 10, shown in Fig. 4, or by any other suitable means to prevent 'lateral movement of the rail on the chain The rails 11 are of any suitable cross section' and are similar tov those in ordinary -use Specification of Letters Patent.

with the exception of a small rib 12 depending from the baseunder the web. This rib engages in the groove 9 of thechair and prevents lateral movement of the rail oii the chair. a

In the' forni sho-wn in Fig. 4, this rib is ieplaced by a groove 13, cooperating with .the rib 10 of the chair.

stood that the groove 13 may be of sufficient width to embrace the entire top of the chair, thus eliminating the necessity of a special of rail is that it may, be laid in the ordinary require recesses formed in the ties, if the chair was not used. On the other hand, such ribbed type of rail would be more secure as the rib engaging in the tie would. remove much strainfrom the spikes.'

The preferred method of attaching the chair to the ties is by means of clamps 14 on the outside of the rails and similar clamps 15 between the'rails. These latter clamps 15 extend from rail to rail and also form distance bars. These clamps overlap the flanges of the rail chair and are secured to the ties by bolts or'spikes 16. As the rail chair is not of suitable form for the use of fish plates to connect the various sections,

one end of each member is provided with a project-ing tongue 17 of reduced size, while the opposite end is provided with a recess 18 for the reception of the tongue of the ad-V rflanges Vat the time that the same was laid,

with the threaded ends upand projecting a suitable distance above the foundation 19. The rails which preferably have tlienecessary bolt holes formed in the base flanges thereof are placed in position onthe chair, and secured by nuts 21. The pavement is then completed, f one or more rows of re.- movable` blocks 22 being placed neXt to the rails, where the Vpavement is of asphalt or It will be under-V 'rib 10. An advantage of the grooved. type :sov i ioo a like material. If the pavement is entirely of the block type, no special provision Will be required.

Ihen the rails become Worn out, they may be replaced by simply removing a single row of blocks on each side thereof, removing the Worn rail and substituting a new one. As the ties and rail chairs are em bedded in the foundation of the pavement, the entire track foundation becomes practically one piece and integral with the road. Furthermore, this embedding of the ties and rail chairs protects the same to a very large extent against decay, so that a single track foundation will outlast many sets of rails. As it is not necessary to disturb the track foundation in any Way nor to gage the distance between the rails in relaying the track, the same may be accomplished With great rapidity and vvith practically no interruption of traflic.

Having thus described my invention, I declare that What'I claim is A railway track comprising a plurality of ties, flanged rail chairs mounted thereon, each of said chairs having at one end a Jtongue and at the opposite end a recess for the reception of the tongue of the adjacent chair, clamps spacing said chairs and securing the same to the ties, rails mounted on said chairs, bolts passing through the chair and rail, flanges securing the rails in position and locking ribs on said chairs and rails to prevent lateral movement of the rails on the chairs.

In Witness whereof I have hereunto set my hand in the presence of tivo Witnesses.

JOSEPH P. MAROIS.
