' I This invention relates to an improved railway tie plate or chair, and it has reference toan improvement in the general construction of sai reinforcing chairs, whereby to permit the rails to be seated and fastened thereto.

.In carrying out the invention it is my aim' to generally improve upon structures of this class by providing a novel arrangement of features and details which cooperate in a manner to produce a moreeflicientrail chair construction, one which is economical, susceptible of rapid installation and removal, and 1 otherwise eflicient in fulfilling the requirements of a structure of this class in a highly.

satisfactory and de endable manner.

7 Another object o? the invention is to provide novel metallic channel shaped chairs or bed plates made'in left and right t es to permit throwing in to compensate or adjustment as the rails wear.

Other features and advanta es of the invention will become more readily apparent from the following description and drawings.

In the drawings; Figure lis a fragmentary elevational view showing the opposite end portions of the wooden tie with the metallic chairs fastened thereto and the rails fastened thereon. Figure 2 isa top plan view of the structure ?.seenin Figure 1, a Figure 3 is a view like Figure 1 with portions broken away and shown-in section, and further showin the'cooperation of features and the Shifte or adjusted position of one ofFthe rails. f Y 1 i re4' isa ra enta top p an view ofvon hf the chairs v i t h the l hil removed.

'Figurej is a pers ective view of the complemelital chair, an

Figurefi is a perspective view shown in Figure 3' by-itself.

In the drawings in Figure 6=the reference of the chair character 7 designates a chairor bed plate,

which-is adapted to be fastened on the wooden'tie 8. This plateeis of general U-shaped configuration and includes acentral web por-' tion 9 which forms thebed for the base flange of the complemental rail 10. The chair .7 is provided with down turned reinforcing and anchoring flanges, 11 provided with almed i929. Serial no. 871,848.

holes to accommodate the fastening bolts 12 and 13. These bolts extend transversely through the tie at about the center and in the same horizontal plane. The bolts are of course in spaced parallelism, In accordance with this particular species of chair, it is provided on one side with an'upstanding vor elevated portion constituting a shoulder14. In addition it is provided with staggered holes 15 and 16 to accommodate spikes 17 and 18. The, tie is notched out adjacent one end as at, 19 to permit the portions 9 and-14 to fit 'there-' in to dispose this ortion of the chair sub- 'stantially flush with the tie top.

The complemental rail is designated by the reference character 20 and this cooperates with the chair 21. This is of the same configuration as the chair shown in Figure 5, and

it includes the central web portion 22011 the opposite sides of which are spaced parallel j elevationsforming shoulders 23 and 24, producing a channel in which the base flange of the rail 20 is seated. Here again I provide holes 25 and 26 for the spikes 27 and 28. In addition the attachin flan'ges29 are prbvided, and these are astened to the tie by the cross bolts 30 and, 31. .The tie has its end portion notched to permit the .web portion of the chair to be seated flush therein.

Particularly do I wish to emphasize the reinforcing flanges for the wooden tie and thebolts for fastening the metallic'chairs in place. Then too I call attention-to th fact that the openings 15 and 16 of the 1e and chair 7 are enlarged somewhat. This is to allow for the so called throwing in of the rail at -predetermined intervals. After the" rail is worn a certain distance it 'is customaryto shift the rail over, that is, in a direction from left to rightin Figure/31 Normally it occupies the position see 9 in Figure .1, and after the wear takes place it is moved over slightly th the position seen in Figure 3. This necessitates withdrawal of the s ikes 17 and 18, and placement of wedge p that the rail can be shifted over at least a ugs 32 '95- 'therein.- These plugs constitute fillers'and" half inch which-is the reason for the elongated formation or enlarged holes 15 and 16.

It is obvious that the spike holes are such as to permit regular spikes to be used in anchoring the rail chairs to the tie and the rail to the chairs. When the rail in thrown in a half inch or so,- the track men will insert one of their regular tie plugs (a wooden plug the same size as the steel spikes) and this will '0 eflectively ill the hole where the spikesis removed. on it will be necessary only to insert the spike in a new place after the rail is thrown in. The bolts of course will not be disturbed at an time during the life of said tie, the only di erence in the position of the bolts is that the bolts on the side where the rail is to be shifted will have to be one half inch nearer together than on the other end or side to allow for the adjustment.

p A careful consideration of the description in connection with the drawings will enable persons skilled in the art to which the inven tion relates to obtain a clear understanding of the construction, method of. assembly, handling, adjustment, etc. Therefore, a more lengthy description is believed to be unneces- "Minor changes in shape, size, materials, and rearrangement of details coming within I the field of invention :elaimed ma be re- ,sorted to in actual practice if desire Having thus described the invention what I claim as new and desire to secure by Letters Patent is f t5 A rail chair of the character described comprising a web portion having transversely ex tending slots adjacent its longitudinal marginal sides for the passage of anchoring s ikes, said web portion being further pro- 00 vided, on its upper face, with a longitudinally extendin raised marginal portion pro-' viding a rai v engaging shoulder intersecting the respective slot, all of the slots being of a size to permit the spikes to be shifted therein 46 to permit the rail to be shifted laterally and secured in shifted position on the web portion.

In testimony whereof I aflix my si ature.
