ROBERT SUIT-IERLAND, OF DELIA; ALBERTA, CANADA.

RAIL-CHAIR.

To all whom t may concern Be it known that I, ROBERT SUTHERLAND, a citizen of Canada, residing at Delia, in the Province of Alberta and Dominion of Canada, have invented new and useful lmproveinents in Rail-Chairs, of which the following is a specification.

The present invention relates to improvements in chairs for railway rails, and is designed primarily to effectively support the rails upon a track, to prevent the spreading or turning of the rail.

A further objectof the invention is the provision of a chair for railway rails which shall include a chair proper having its base fluted for a suitable distance to receive the base flange of the rail and to permit of the expansion and contraction of the rail or rails with a minimum amount of friction by the chair.

l further aim to provide a chair upon which the rail may be effectively and quickly positioned, and further whereby the said chair may be easily and quickly secured upon a broken rail to afford the same its full strength.

It is a still further object of the invention to provide a rail chair which shall embody ay base that is fluted for the reception of the rail, the base having one of its ends formed with a vertically extending` portion with which is integrally formed a Harige which overlies the base, the free edge of the flange as well as the inner base of the vertical eX- tension being inclined, the opposite end of the chair being provided with rail flange engaging hngers, which are spaced from cach other to further provide the base of the chair with a central extending portion having an opening for the reception of a spike or other securing element, and I also provide av wedge brace member which is adapted to coact with the vertical wall and the overlying flange and which has inclined portions that engage with the inclined portions of the ilange and vertical member of' the base, the said flange and base being formed with registering openings and the brace being also provided with an opening which partially registers with the said openings, and which, when a wedge spike or other securing element is inserted within the openings, is brought into register with the openings in the chair, thus moving the brace 4transversely into tight engagement with the rail or rails.

Specification of Letters Patent.

serial no. 774,870.

Vith the above recited objects in view, and others which will appear as the nature of the invention is more fully understood,

.the improvement resides in the construction,

combination and arrangement of parts set forth in the following specification and fall'- ing within the scope of the appended claims.

In the drawings: Figure 1 is a transverse sectional view through a rail supported by my improved chair, the chair being shown in elevation, Fig. 2 is a side view looking toward one of the faces of the chair, Fig. 3 is ka central longitudinal sectional View through the same, Fig. 4 is a top plan view, Fig. 5 is a perspective view of the chair, Fig. 6 is a similar view of the brace member, F ig. 7 is a view illustrating the manner of inserting the rail upon the chair, the dotted lines illustrating the first position of the rail when placed upon the base of the chair as wellas the final position of therail upon the chair, and Fig. 8 is a view illustrating the manner of attaching the chair to a broken rail.

Before proceeding with the description of the invention it is to be stated that the chair may be employed for securing the meeting ends of two rails, but in the following description only one rail will be referred to, and the chair will be set forth as a bearing member for the rail to prevent the tiltingA or spreading of the rai-'l as well as a means for effectively connecting the brokenv ends of a rail.

Referring to the drawings in detail, the numeral 1 designates a tie, 2 the chair in its entirety, and 3 the rail which is adapted to be received upon the chair.

rlhe chair embodies essentially a flat has 4: which is of al greater length than the length of the base flange of the rail 3, and which is of 'av width approximately corresponding to the width of the tie 1. The base is provided upon one of its ends with anv integrally formedl vertical extension 5', and the inner face of the said extension is thicker at one otite ends than at its opposite end to providethe said inner face with what may bel'termed an inclined wall. Integrally connected with the extension 5 is a flange 6 which overlies the base of the rail and which has its underface beveled or inclined at an opposite angle to the angular upper faces of the base flange of the rail. |The distance between the flange 6 and the base l is, however, greater than the"thiclniess of the base flange of the web, and the flange has its edge extended from the vertical wall 5 a slightly greater distance than the distance between one of the longitudinal edges of the base flange of the rail and the web of the said rail. The opposite corners of the base d are integrally formed with hooks 7, the said hooks overlying the base and the upper portions of the same being beveled or inclined, so that the space between the hooks and the base correspond to the cross sectional contour of the base flange of the rail, with which the said hooks are adapted to engage. Formed integrally with and arranged between the hooks 7 is a flat base extension S which is centrally provided with an opening 9, the said opening being adapted for the reception of a securing spike when the chair is arranged upon the tie 1.

The base 4 has its upper tace fluted or corrugated, as at 10, the said `liuted portion eX- tending from the inner vertical walls of the hooks to a distance therefrom equaling the width of the base flange of the rail 3, so thatthe said base flange of the rail will be seated upon the said liuted portions when the rail is arranged upon the chair. The portions of the base projecting beyond the terminals of the fluted portion, or that portion disposed below the base flange 6 is smooth and un broken.

ln carrying the rails upon the chair, when the said chair is secured to the tie 1, the rails are rst arranged at an angle so that one of the sides of the base flanges is disposed between the base d and its overlying flange 6. The opposite longitudinal edge of the rail is then free to pass to the base without contacting with the hooks 7, and the rail is then slid transversely until its Vflange, upon one of its sides, is received by the hooks 7 and its base arranged upon the fiuted portion 10.

In order to sustain the track against lateral movement upon the chair, l provide a brace block 11. This block in cludes a base, the lower wall of which is straight and which adapted to be received upon the walls upon the base d between the vertical extension 5 and the fia-nge 6 thereof, and so the upper face of the base is inclined, as at 11", to conform to the shape of the underface of the flange G. The outer edge of the base 12 is `beveled cr inclined in the saine direction. or angle as is the inner face of the vertical extension 5 oiE the base of the chair, as indicated by the numeral 13, and the upper beveled face 11 terminates in a beveled or inclined wall 15 which is arranged above the said beveled face 11 and which is formeel integrally with the rail engaging member 1G of the brace blockn The wall 15 is inclined or beveled longitudinally to agree with the beveled edge of the flange 6, and the base 12 is provided with a shoulder 1'? which is longitudinally straight, or disposed at a right angle to both the ends of the block 11 and the sides or ends of the chair 2, the said shoulders 17 being provided by the bottom and beveled wall 18 of the rail engaging member 16. The wall 17 is adapted to contact with the outer longitudinal edge of the rail 3, and the beveled or inclined portion 18 is adapted to overlie the iiange upon the outer face of the rail, while the rail engaging portion of the block is adapted to have its inner face contact with the outer web ci' the rail, and ir" desired, the top of the said member 16 may underlie and frictionally contact with the ball of the head upon the opposite side of the rail 8. The brace block 11 is arranged upon the chair by sliding the same from one of the sides of the said chair, so that its inclined portions 13 and 15 will ceact with the inclined inner wall et the extension 5 and with the end of the flange 6. This wedge-shaped engage nient of the block with the chair will forcibly bring the rail engaging portions of the block tightly against the rail as well as forcing the said rail into engagement with the hooks 'l' of the chair. The overlying iange 6 and the base d of the chair 2 are provided with registering openings which may be designated by the numerals 19 and 2O respectively, while the beveled or inclined portion 11 as well as the base 12 of the block 11 have also an opening 21. 'l'he opening 21 has its inner wall preferably not in alinement with the inner wall provided by the openings 19 and 20, so that when a wedge securing member 22 is inserted through the fpcnings, the block 12 will be forced more tightly into Contact with the base. This feature, however, is not essential, as the wedge engagement ci the bloclr with the beveled walls provided by the chair is amply snflicient to effectively force the block into tight engagement with the rail, and the opening 21 may register with. the openings 19 and 20, and the securing element 22 may be in the nature of a spike which enters the tic, and which in connection with the spilre passing through the opening 9 eiliectively secures the device upon the tie 1 1When the device is employed for securing the broken ends of a rail, the chair is sustained at an angle and the space between the flange 6 and the base i ofthe chair is sufficient to permit of the outer base flange of the rail being received therein. Wlhen this is accomplished, the chair is elevated to a horizontal position and is moved until the inner flanges of the rail are received by the hooks 7. After this is accomplished the wer ge block is inserted upon the chair, and the securing element 22 is now in the nature of a nut and bolt, or of' a wedge-pin provided with openings for the reception of a @Otter pin,

ilo

the base plate and having an angular underr surface, said flange having its longitudinal edge inclined in the direction of the inclination of the said extension, the opposite corners of the base being provided with inturned hooks, the base having an extension between the hooks which is formed with a spike receiving opening, a rail adapted to be passed under the flange on the base and brought into engagement with the hooks, a brace block having a rail engaging portion adapted to be arranged between the overlying flange, and the base, and having its' longitudinal edge conforming with and engaging against the said extension` the said rail engaging portion having its upper surface provided with a shoulder extending throughout the length thereof, the said shoulder being inclined throughout its length and adapted to be engaged by the inclined longitudinal flange, and means for securing the said block on the chair, the portion of the chair whereon the rail lies being fluted.

2. A rail chair including a base having one of its edges provided with a vertical extension and a flange having an angular underface integrally formed with the eX- tension and overlying the base, the edge of the flange and the inner wall of the eXtension being inclined from one of the ends of the chair to the opposite end thereof, the corners of the opposite longitudinal edge of the base being integrally formed with inturned hooks which also overlie the base and which have their underfaces inclined, the portion of the base between the hooks being extended and being provided with a spike opening, the hooks adapted to receive the base flange of the rail, and the portion of the base upon which the rail rests being fluted, a brace block, said block including a base which is adapted to rest upon the unbroken surface of the base of the chair below the underlying flange thereof, the base of the block co-nformin to the space between the said overlying fnge and base and having its longitudinal edge inclined to agree with the inclined inner face of the vertical extension of the base, the inclined upper wall of the base being provided with a shoulder which agrees with the longitudinal inclined edge of the base overlying flange, the said shoulder being provided upon a rail engaging enlargement formed with the block, the underface of' the enlargement being beveled to overlie the base flange of the rail, the base of the block as well as the overlying flange and the base of the chair being provided with openings, and a securing element passing through the openin s.
