RAIL-CHAIR.

SPECIFICATION forming part of Letters Patent No. 784,727, dated March 14, 1905.

7 Application filed June 1,1904. Serial No. 210,640.

.To all whont I I'J 'I H/II/y concern.-

Be it known that I, JOHN McADAMYoUNc, a

subject of the King of Great Britain, residing at Keremeos, county of Yale, in the Province of BritishColumbia, Canada, have invented certain new and useful Improvements in Rail- Ghairs; and I do hereby declare that the following is a full, clear, and exact'j description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. This invention relates to certain new and useful improvements in railwaymhairs that is, chairs adapted to receive the meeting ends of railway-rails; and it consists in the novel construction and arrangements of parts, which will be hereinafter more fully described, and particularly pointed out in the claims.

The object of the invention is, to provide a simple and effective form of railway-chair for the purposes for which such devices are used, said chair being strong and durable in its constrnction and easily applied and comparatively inexpensive to manufacture. I accomplish this object by the construction illustrated in the accompanying drawings, in which Figure 1' is a plan View of the improved chair in position for securing the meeting ends of two adjacent rail-sections. Fig. 2 is a transverse sectional view of Fig. 1, taken on line 2 2 thereof. Fig. 3 is a similar section taken on line 3 3 of Fig. 1. Fig. 4 is an isometric perspective view of the chair detached. Fig. 5 is a similar view of one of the locking-lugs hereinafter referred to, and Fig. 6 is a similar view of the companion locking-lug.

Similar numerals of reference indicate corresponding parts in all the views.

Referring to the parts, 1 1 are railway-rails, comprising the usual heads with the Web portion 2 and base-flanges 3. The chairs 4: comprising the present invention are constructed and formed on one side with upwardly-projecting lugs 5, having rounded ends adapted to bear directly against the web portion of the rail between the head and bottom flange thereof. The opposite side of each of said chairs is also provided with an upwardly-projecting lug 6, which is formed on its inner side of a curved configuration, as best shown in the sectional view Fig. 3 and in the perspective view Fig. 4, and between the said lugs 5 and 6 a recess is formed for the reception of the lower flange of the rail. Adapted to be projected between the rail-Web 2 and the inner face of the lug 6 is a locking-wedge 7, which, as noted in Fig. 6, is provided with the narrow elongated nose portion 8, adapted to contact with the rail-web at one side, and is provided at its opposite end with the cam-shaped portion 9, which is adapted to occupy the space vertically beneath the inner wall of the lug 6. Connected with the wedge 7 is astem 10, which is preferably cast within the lug or rigidly connected therewith, the said stem having formed on its free or outer end the eye portion 11. In Fig. 5 a companion lug 12 is shown, which has approximately the contour of the lug 7, but is provided with the vertically-extending flange 13, formed integral therewith, which flange serves as a stop, as best shown in Fig. 1, to prevent the excessive thrust of the said wedge 12 within the section 6.

In assembling the parts for practical use the chair 4; is nailed or otherwise secured to the ordinary railway-ties 14 by spikes or other means, and the rails 1 are slid longitudinally thereinto, as shown in the drawings, after which the lug 7 is slid longitudinally within the lug 6, the nose portion 8 contacting with the rail-web and resting upon the flange thereof until the eye 11 extends beyond the chair, as shown in Fig. 1, after which the wedge 12 is slipped into position, the pin 10 being projected through the longitudinal opening 15, after which the wedge or key 16 is placed in position in the eye 11 to lock said wedges firmly in position, and thereby secure the meeting ends of the rails. When these wedges are inserted between the adjacent lugs and the rail, a tight joint is formed between the parts, which secures the rail against displacement. The lugs situated upon the opposite side of the rail firmly bear against the web and slightly support the head, no other form of fastening means being used at this point than heretofore described. When the wedges are removed,

the rails can be readily withdrawn from the chairs, or the chairs can be slid longltudinally upon the rails for the purpose of releasing the ends of the rails therefrom. It is my purpose to place one of the chairs at each joint of the rail, insert the wedges as described, and by this means lock the rail-sections together, thus preventing lateral displacement of the rails owing to traflic upon the road.

While I have shown in the accompanying drawings the preferred form of my invention, it will be understood that I do not limit myself to the precise form shown, for many of the details may be changed in form or position without affecting the operativeness or utility of my invention, and I therefore reserve the right to make all such modifications as are included within the scope of the following claims or of mechanical equivalents to the structures set forth.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. Ina device of the character described, a chair having a base portion, lugs projecting inwardly and upwardly from opposite sides of said base whereby flange-recesses are formed, a wedge adapted to enter one of said recesses, a pin connected with said wedge, a second wedge and means for locking the said wedges together.

2. In a device of the character described, a chair having a base portion, lugs projecting inwardly and upwardly to form recesses of different sectional elevation at opposite sides of said chair, a plurality of slidable lugs in the higher of said recesses, a pin in positive engagement with one of the wedges, said pin being adapted to be projected through an opening in the other of the wedges, and looking means adapted to engage with the pin.

3. In a device of the character described, a chair having lugs projecting inwardly and upwardly from one side thereof, each of said lugs being adapted to bear against a rail-web, an opposing lug extending to a relatively higher plane and forming with the base of the chair a recess, a wedge, a companion wedge having a stop-flange thereon and a perforation extendingtherethro ugh, and means adapted for locking said wedges together.

4. In a device of the character described, a chair having a base portion, a lug extending toward the central portion thereof, an opposing lug extending to substantially the plane of the upper surface of the rails and forming a recess, in combination with a plurality of slidable wedges, and locking means therefor.

5. In a device of the character described, a chair having a base portion, a lug extending toward the central portion thereof, an opposing lug extending to substantially the plane of the upper surface of the rails whereby a substantially continuous support is provided for wheels passing the joint, in combination with a plurality of slidable wedges, and locking means therefor.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
