Application filed April 18,

T 0 all 107mm it may concern Be it known that 1., Cinemas lllALITCH, a citizen of the United States, residing; at Hamilton, in the county of Butler and State of Ohio, have invented certain new and useful Improvements in Rail Chairs, of which. the following is a specification.

My present invention. which generally relates to im rovenients in that type of rail chair and joint structures disclosed in my Patents No 1.390.919, dated September 13, 1921 and No. 1311,7238, dated r-rpril t, 1.922, primarily has tor its purpose to provide a new and improved rail chair, of the general type stated, oil," a relatively simple construction, in which the direct connection oi? the rail ends and the chair is a boltless one and in which provision is also made for a more convenient and positive interlocking engagement of the rail enc s and their coengasing chair parts, and in such manner that the us semblage of the chair and the rails is tacilitated when the chair parts are to be secured upon the rail tie.

In my Patent No. 1.;l1lgi'38 betlorc mentioned the chair structure includes iron and wooden wedges and wooden filler members that are adapted for being inserted, in the direction of their length at each side of the rail web and between the said web and the vertical flanges oi the opposite or two-partrail chair sections.

My present invention does away with the use of wooden wedges or tiller members. since all the parts thereof are of metal. The present invention includes an ini in'oved de sign of a single malleable iron wedge, that is not adapted to be driven into operative position by forcing it endwise into place, as in the patented construction mentioned but is adapted for being driven., in vertical direction along the full length thereof, beti'veen the vertical chair flan e at one side of the rail and a filler member held against the jacent side of the rail web, the filler and wedge members being also provided with means interlockably connecting; them to hold the wedge from working loose in horizontal direction.

Another object of my present invention is to provide combination of rail chair parts, for engaging the ends oi adjacent rail sec tions in which is included a single wedge member that is designed for being on god by and held from Working loose in vertical Specification. of Letters Patent.

direction by the impact of the flanges of the passing Wheel which tend to constantly hold the said single wedge to its downward or wedging position and secured against loosening upwardly under the jars and hammering action incident in the use of rail chairs oi the general type referred to.

In the construction disclosed in my patent aforesaid, the rail ends receiving seat or chair body is held down by spikes whose heads directly engage the opposite base flanges of the chair or seat body proper.

in my present construction provision is made, by reason oi special formation of the said base flanges oi the chair, whereby the spikes, when driven home, are caused to engage the opposite flanges of the rail base to thereby eli'ectively hold down the rail end under the varying condition of expansion and contraction of the parts and in a more positive clam ping engagement with the chair or seat base than is possible where the spikes engage the chair flanges. as in my patented construct-ion mentioned.

With the above and other minor objects in view and which will hereinafter be incident-ally mentioned, my present invention coniiprehends an improved rail chair which embodies the peculiar features of construc tion and novel arrangement of the parts tully mentioned in the following detailed descriptioin specifically stated in the appended claims and illustrated in the accompanying drawings, in Which:

Figure l is a perspective view of a pre terred form of my new and improved rail chair. I

Figure 2 is a horizontal section thereof, tak n substantially on the line 2'2 of Figure 3.

Figure 3 is a transverse section of the same on the line 33 oi Figure 2.

4 is perspective view of themeinher which constitutes the filler tor the space one side of the rail web.

Figure 5 is a perspective view of the sin le TVQClgQ member used in my present and rable construction of rail chair.

Figure 6 is a transverse section of my improved. construction of rail chair, taken substantially on the line 66 on Figure 7, and illustrating the manner in which the chair, the filler the wedge member and the rail ends may be held together with the ordinary standard bolts.

Figure 7 is a horizontal section thereof taken substantially on the line 7? on Figure 6, the bolts being omitted.

Figure 8 is a perspective view of the form of wedge used in the modified construction of my invention illustrated in Figures 6 and 7.

In my present invention, the rail chair or seat is a single casting, preferably 10 long, and which, when operatively applied, may, as in my patented chair structure mentioned, lit down in a recess 7 in the top of the cross tie or be secured directly on top of the said tie, as best shown in Figure 6, by a pair of spaced spikes 55 at one side and a midwaypositioned spike 5 at the opposite side, the said spikes, in my present invention, when driven home, engaging the opposite flanges of the rail base, as will hereinafter he further explained.

In the preferred construction of my present in'iprovements, and as best illustrated in Figures 1, Q and 3 of the drawings, the rail chair is a single casting 2, the opposite sides of which each terminate in an upwardly extending vertical flange, one of such flanges, in the present construction, constituting a shoe or filler for directly engaging one side of the webs of the adjacent rail ends and against which the said rail webs are laterally clamped in the manner presently explained.

By referring to Figures 2 and 3, it will be noticed the shoe or filler 2, before mentioned, and which is an integral part of the chair body or casting, is the full length of the chair body and of a thickness to fill the space between the adjacent faces of the webs of the rail ends and the outer vertical plane of the rail heads, as is clearly shown in Figure 8.

designates a filler member or plate and it is of a thicltness similar to the chair shoe 2 and it engages the opposite faces of the rail webs and the said member 3 has a series of horizontally arranged serrations on the faces thereof, the purpose of which will presently he explained.

referring to Figures 2 and 3, it will be observed in my present construction of rail chair, the vertical flange 2 of the chair body is spaced a sufficient distance from the rails to position its vertical face far enough away from the corresponding faces of the rail webs to provide for a proper and convenient fitting of the filler 8 and a wedge member wiich, the practical development of my invention, is a steel bar or plate the full length of the chair body, and is slightlyv tapering from the top to the bottom in cross section.

The inner face of the wedge member f has a series of ratchet-like serrations 40 and these are adapted for interlocking with the like serrations 30 on the filler rneinber 3,

before referred to, and other serrations ll to engage serrations 2 on the member 2 as the said wedge l driven down, its full length, between the flange 2 and the tiller 8, it being understood that as the wedge a is driven down, as stated, the coengaging parts mentioned will be held in a tightly clamped relation. The filler 3 is held from endwise displacement by the provision of lateral studs 31, cast with the filler, which fit into the apertures in the rail web, the latter being of the usual shape to allow for 1 he normal expansion and contraction of the rails without effecting the connection between the said rails and the said filler member 3. I

To hold the wedge +1: against working end- .vise, that is, in horizontal direction, the outer face of the said wedge has one or more vertical ribs eh? adapted for engaging vertical grooves 26 in the adjacent face of the chair flange2 and the inner face of the said wedge i is formed with a series of vertical grooves 457 for engaging correspondingly shapet ribs 37 on the tiller 3, as shown.

By referringmore particularly to Figure 2 of the drawings. it will be seen that one of i the opposite horizontal flanges of the chair has a pair of spaced semi-circular edge notches and the opposite chair flange has a single semicircular notch 22 and the several mentioned notches extend inwardly sufficient v to expose the opposite outer-edges of the rail base flanges to provide for. readtioned low enough to permit the flanges of.

the trur-l: wheels to clear the said high point 454. of the wedge but should, for any reason, the wedge ll loosen or work upwardly, the said 11 'h or crown portion 44 will come within the path of movement of the wheel flanges which, they engage the crown edge of the said wedge at, will force such wedge downwardly back into interlocked engagement with the filler 3 and flange 2 In Figures 6, 7 and 8, is shown a slightly modified arrangement of my present inven' tion, and in such showing instead of providing the filler 8 with studs 31 for interlocking with the rail webs, as stated, the said tiller at one side of the rail and the shoe 2 at the opposite side of the rail, as

also the chair flange 2 are provided with suitable apertures 33%?) and 23 respectively, the said apertures being relatively arranged so that when the several parts mentioned are operatively assembled the said apertures will register with the apertures 60 in the rail webs and when the parts are thus assembled the usual standard bolts 9 may be utilized for clamping the several parts mentioned together in transverse relation, as will be readily understood from Figure 6 of the drawings.

When used in connection with the standard bolts 9, as in Figures 6, 7 and 8, the wedge member is preferably formed with slotways tit-43 that extend upwardly from the lower edge thereof and which are so disposed along the wedge that when the parts are assembled with the wedge down between the tiller 3 and the adjacent chair flange the said Wedge member will be held from working loose in the horizontal direction by the bolts 9.

From the foregoing, taken in connection with the accompanying drawings, the complete construction, the manner in which the chair parts are assembled for use in connection with or disconnected from the rail ends, as may be necessary, will be readily understood by those familiar with railway track construction.

What I claim is:

1, A combined rail chair and joint comprising a chair including a base adapted for being secured upon a rail tie, the said base having a seat, a pair of opposing rail ends whose base portions are received on the chair seat, the said chair having at each side a vertically extended longitudinal flange, one of the said flanges opposing the adjacent web faces at one side of the rail ends, a filler member at the other side of the webs of the rail ends, the said filler opposing its respective adjacent vertical chair flange, a wedge interposed between the said filler and the adjacent rail chair flange, and means for clamping the several parts in interlocked engagement. the said wedge member having its upper edge crowned from the ends toward the center whereby to present a top surface on the wedge adapted for being enweb faces at one side of the rail ends, a liller member that engages the faces at the other side of the webs of the rail ends, the said filler opposing its respective adjacent vertical chair flange, a wedge interposed between the said filler and the adjacent rail chair flange, and means for clamping the several parts in interlocked engagement, said means including clamp bolts that pass through the rail ends, the vertical flanges of the chair and the filler, the aforesaid wedge member having vertical slotways in its lower edge for fitting over the aforesaid bolts when the aforesaid parts are operatively assembled.
