zen of the United States, and ares'ident of.

Perrine, in the county ofDade and State of-Florida, have invented certain new and useful Improvements in Chairs for Rail Joints, of which the following is a specificationq g My inventionrelates chairs for rail joints, and it consists substantially in the construction and manner use herein described and claimed. i I One ofthe foremost objects of the invention is to provide a chair designed to ab solute'ly prevent sagging and side play.

Other objects and advantages will appear in the following specification, ing had to the accompanying I 'whichfzj Figure 1 is a plan view of the improved chair, only so much of a rail being shown as is necessaryto illustrate the application, and

Figure 2 is a cross section onthe line 2-2 of Figure 1. I

Attention is first directed to Figure 2. The chair which constitutes the invention, comprises the sole plate 1, which is formed at 2 to embrace the outer flange 3 of the rail base, thereafter extending vertically into a a part hereinafter properly termed the fish plate 4. The fish plate includes an upward extension 5, which preferably rises slightly above the head of the rail so that it may be engaged by the sloping face of the wheel. The ends of the extension 5 are inclined at 5 so. that there will be no ar when the wheels strike the extension in going over the 'oint. J This extension 5 is of no little importance because it serves to support the weight of the wheels and the train above in passing the joint. The usual pounding, jarring and vi bration occasioned by the wheels 7 moving over the space between two abutting rails 6, is thus entirely eliminated by theprovision of the extension 5. A shoulder 8 flts snugly against the rail head on the outside, as is somewhat common in practice.

There is a recess 9 in the bend 2 in which the outer flange of the rail base fits in a rather peculiar manner. Instead of the walls of the recess contacting similar parts of the flanges 3 throughout, only the innermost part of the top of the recess is intended to engage the flange. The recess then bedrawing, in

to improvements in reference be- "tighten them at comes. slightly'larger, so as to leave the tapering space illustrated.

" Observa'tionhas shown, that ajar can occur even when the rail ends '6 are'tight together, thus indicating that the jar is not produced by the wheels passing over an open space between adjacent rails. The jar is really caused by the sagging of the rails at the ,joint, thus forming a valley into which the wheels ride, striking the rail at the opposite side from thejpoint of entrance and thus causing what is commonly known It isthefpurpose of this invention to prevent sag ing, thus eliminating the jar,"and also sidewise play of the rails. When the lateral thrust of the car wheels 7 is exerted againstthe, railsat the joint,a tendency to the bottom, and the chair therefore becomes self-adjusting by virtue of the slight flexibility afforded as just described.

In making these plates, they will be rolled Y a trifle close in the space'between the point 10 and the bottom of the sole plate 1, with suflicient space at 9 so that there'will be no interference, always permitting a perfect fit at 10. By a tool, designed especially for the purpose of fitting these plates, the sole plate will be supported along the inner edge and pressure applied to the fish plate and chair between and on either sideof the rail securing bolts. This will insure a close fitat the points 10, and across the top of the sole plate 1. I By "having a proper thickness of plate over the space 9, the strain will be transmitted through the bend 2 to the plate 1,

which will'then be in tension and offer a sufficiently strong mass from the top of the extension 5to the bottom of the plate 1, to resist sagging.

Spikes p the points indicated 10, be "comesevid'e'nt. The space afforded by the peculiarshape of the recess 9 provides am I ple room for the tightening ofthe flange at llsecure the chair in place. The r bend 21s vertically recessed at 12 to provide There is another feature of no little importance. many rail joint-making consti gctions, a'f lock washer 16 is used in connection with the nut 17 of the securing bolt 18. But instead of letting the lock Washer 16 rest on the outer surface of the chair 4, a recess 19 is provided for its reception. The now common danger or the washer jarring out and leaving the bolt loose in case the washer should break, is entirely obviated by housing the washer in the recess. Even should it break, the bolt cannot come loose because the parts of the washer are prevented from falling away.

i hile the construction and arrangement of the improved chair as herein described and claimed,is that of a generally preferred form, obviously modifications and changes may be made without departing from the spirit of the inventionor the scope of the claims.

v lclaimz- I a 1. The combination in a rail joint, of a sole plate su'fficiently wide to extend well beyond the inner flangeot a rail base, perforated to receive spikes; an inner fish plate bearing against a rail head and inner flange, extending from the flange and provided with notches registering with said spike perfora- U ti-ons; a bent portion extending from the sole plate and embracing the outer flange of a rail base, including a recess contacting said 'aseflflahge at the innermost point to provide adjusting space; and a fish plate extending from said bent portion, includin a shoulder contacting beneath a rail head, with an upward extension coming flush with the to of the rail head for the support of car wheels across the rail joint and a recess in the side of the fish plate for the housing of a lock washer of a bolt which secures the parts together. i

2. The combination in a rail joint, of a sole plate sufficiently wide to extend well beyond the inner flange of a rail base, perforated to receive spikes; an inner fish plate bearingagainst a rail head and inner flange extending from the flange and provided with notches registering with said spike perforations; a bent portion extending from the sole plate and embracing the outer flange of a rail base, including a recess said bent portion contacting said baseflange at the innermost point only to provide adjusting space; and a fish plate extending from said bent portion, including a shoulder contacting beneath a rail head said fish plate havin a recess in one side for housing a lock Wasner of a bolt which secures the parts together.
