Specification of Letters Patent.

Patented Jan. 26, 1915.

To all whom it may concern:

Be it known that 1, AUGUST Gr. LIEB- MANN, citizen of the United States, residing at Butte, in the county of Silverbow and State of Montana, have invented certain new and useful Improvements in Rail-Joint Chairs, of which the following is a specification.

This invention relates to railway track appliance and particularly to rail chairs.

The primary object of the invention is the provision of a chair so constructed that it may be used at rail joints for holding the joined ends of. rails and will accommodate the usual angle bars or fish plates mounted at the rail joint.

A further object of the invention therefore is to provide a chair which will act to brace joined rails and which will provide for lateral and vertical adjustment of the rail without any loosening or readjustment of the primary fastenings of the chair to the tie or the joined rail ends.

A further object of the invention is to provide a rail chair of this character so designed that the proper support will be attained at the joint independent of re-spiking ties or joining of rails, which chair can be cheaply made of rolled steel.

A further object of the invention is the provision in connection with a chair of the character described, of spikes so formed as to provide for vertical adjustment of the joints upon shims and lateral adjustment for gage of track.

A further object of the invention is the provision in connection with a chair and a peculiar form of screw spike, of means whereby the rail joint may be either laterally or vertically adjusted with relation to the bed plate of the chair without any disturbance of the primary fastenings of the chair to the tie.

Other objects will appear in the course of the following description.

The invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of a portion of a tie, a rail thereon, and the improved chair applied thereto. Fig. 2 is a side elevation of the construction shown in Fig. 1, the rail being shown in section. Fig. 3 is an end elevation of the-construction shown in Fig. 1.

Referring to these drawings A. designates a tie and B a rail. The tie may be of any suitable form but is illustrated as an ordinary wood tie. The rail is illustrated as of standard cross section.

Mounted upon the upper face of the tie and having a width preferably equal thereto, is a bed plate 2, this bed plate having at its ends oppositely disposed vertical webs 3, these webs forming abutments. The webs 3 extend inwardly from the ends of the bed plate a predetermined distance and the in ner ends of the webs are spaced from each other a distance greater than the width of the base of the rail joint. Each web is provided with an opening 4 for the passage of an adjusting wedge and with an opening 5 for the passage of a compression bolt. It will be noted that the base plate with its abutments is T-shaped in cross section and that his bed plate or body portion of the chair may be designed from ordinary structural steel having a T-shape in cross section.

Disposed on each side of the rail B is an angle bar or fish plate designated C. As illustrated, each angle bar C has a basal portion D which engages beneath the base of the rail B, these basal portions of the opposed angle bars very nearly meeting. This is a common and ordinary form of rail joint, and further description is unnecessary except to say that preferably and as illustrated, these angle bars fit between the head and base flange of the rail and that the upper faces of the base flanges of the angle bars are formed with shoulders cl.

Disposed one on each side of the webs or abutments 3 are the fishing angle braces designated 6. Each of these braces comprises a vertical web 7, as best illustrated in Figs. 1 and 3, which is formed with inwardly turned flanges 8 at its upper and lower mar ins, these flanges engaging against the face of the corresponding abutment 3. The material of each of the fishing angle braces is outwardly turned at the base of the portion 7 as at 9. The vertical portion 7 is longer than the angularly extending'portion 9 as illustrated in Fig. 1, so that the vertical portion or web of each fishing angle brace extends over and bears upon the upper face of the base of the adjacent angle bar. These projecting portions of the webs 7 are scarfed or otherwise formed, as at 10, so as to engage snugly with an have the same contour as the base of the adjacent angle bar. The particular form of this scarf will, of course, depend upon the cross sectional form of the angle bar. The base of each fishing angle brace is longitudinally slotted as at 11 for the passage of a screw spike, designated 12. These screw spikes have a peculiar form. Each spike has a screw threaded shank 13 which is adapted to pass through a perfora tion in the base plate and into the tie, and the upper portion of the screw spike is threaded as at 14: for engagement with nuts 15. At the meeting point of the screw threads 14 with the screw threads 13 each screw spike is formed with a shoulder 16 which normally bears upon the upper face of the plate 2. The upper end of each screw spike is formed with a many-sided head 17 whereby the screw spikes may be turned.

Each of the fishing angle braces 6 is slotted, at 18, for the passage of an adjusting wedge 19 and passing through the brace and through the perforation 5 in the adjacent web or abutment 3 is a compression bolt 20, one end of which is headed and the other end of which is screw threaded for engagement by a nut 21. Preferably the wedges 19 are locked in position by means of cotter pins or bolts 22. It will be seen from Fig. 3 that by having the flanges 8 bear against the side faces of the webs or abutments 3, the braces are spaced sufliciently apart to receive between them the head of one of the bolts 23 which hold the fish plates or angle bars to the rail. In case the chair is used between joints, this space would contain a wood bearing block. While this rail chair may be used with or without a shim, there is illustrated a shim 24: disposed between the upper face of the bed plate and the basal portion of the angle bars. Shims of various heights or no shim at all, it will be understood, may be used. In practical use the rail with its attached angle bars is first set down in the space between the inner ends of the webs or abutments 3 and properly adjusted therein. The fishing angle braces 6 are then disposed one on each side of each web 3. These fishing angle braces are forced in against the rail or joined rails by means of the wedges 19 and when in position the wedges are prop erly locked by bolts or cotter pins 22 and the braces compressed against the webs 3 by means of the compression bolts 20. Vhen it is desired to elevate the rail the jamb nuts 15 are loosened and a shim is disposed beneath the bases of the angle bars at the junction of the rail ends. The braces are likewise lifted, the openings in the webs 3 being large enough to permit lateral and vertical movement of the compression bolts, and the braces locked in position by means heretofore described. It is obvious that by loosen ing the jamb nuts 15 and driving one wedge 19 in while driving the other wedge out, that the fishing angle braces, together with the rail, may be laterally shifted so as to adjust the rail to gage. The slots 11, of course, permit a lateral movement of these fishing angle braces.

There is provided by the construction heretofore described, a secure fastening for rail joints wherein the greater stability of the joint is attained and which allows for lateral and vertical adjustment without disturbance of the primary fastenings of the chair to the tie and without the necessity of respiking the tie. Furthermore, the rail chair and its accompanying parts may be formed of rolled steel and thus the chair may be made relatively cheap. By the use of screw spikes having the peculiar form illustrated and described, I provide for a rigid attachment of the bed plate to the tie but permit of a precise adjustment of the railbraces to suit the elevation or depression of the rail or for widening and narrowing of gage.

By providing a plate having a relatively great area which rests upon the face of the tie, cutting or crushing of the tie by the rail joint deflection is eliminated and by doing away with necessity of respiking the life of the tie is greatly increased. Under these circumstances it is possible to use treated ties. Treated ties ordinarily are too expensive to use where the life of the tie is greatly shortened by cutting and crushing action and by the necessity of constant respiking.

It is to be particularly noted with regard to this chair that it braces the rail and joined rails against vertical and lateral thrust and against tipping thrust so that the rail or rail joints are securely held, the head of the rail bears upon the upper edges of the angle bars, the rail braces bear upon the entire extent of the angle bars and therefore bear downward upon the full upper face of the base flange, and any tipping thrust that is transmitted to the rail braces will in turn be transmitted to the vertical webs 3 which are of a design best calculated to resist this tipping thrust. The bolts 20 are designed to compress the angle braces solidly against the vertical webs 3, thereby making a thoroughly tight joint between the braces and webs and bracing the vertical webs or abutments against warping or twisting strain. The angular braces 6, therefore, not only brace the rail against any tipping strain but brace the vertical webs against any outward deflection under stress.

It is obvious that the chair may be used to support either joined rails or the rail between joints. p

In that this chair permits of a vertical and lateral adjustment of the rail and yet provides for a solid fastening of the rail to the tie and for the adjustment of the rail without the necessity of respiking or change in the primary fastening, it conforms to the requirements laid down in the final report of the Block Signal and Train Control Board of the Interstate Commerce Commission.
