CHARLES MALITCH, OF HAMILTON, OHIO.

nuncnam.

To all whom it mayconcern Be it known that I, CHARLES MALITGH, a citizen of the United States, residing at Hamilton, inthe county of Butler and State of Ohio, have invented certain newand useful Improvements in RaiLChairs, of which the following is a specification.

My invention, which generally has reference to that class of rail joints of boltless construction, more particularly has reference to improvementsin the particular form of rail chair disclosed in my Patent No. 958,964, dated May 24, 1910, and primarily my present invention has for its purpose to render the construction of the form of the chair disclosed in my aforesaid patent more economical and more compact, and in Which the means for holding the wooden wedges thatclamp the adjacent faces ofthe rail Web and thechair, is simplified and yet effects the desired engagement with the wedges, and which tends to positively hold the wooden wedges from working loose or working endwise out of their rail and their clamping adjustments.

hMy present: invention includes in addition to the type of rail chair structures disclosed in my patent before referred to, a thin steelwedge that is held transversely of the chair between the abutting ends of the rails and which has the cross sectional shape of the rail and whose rail web engaging portion, when the parts are as sembled, extends laterally for entering into the opposing wooden wedges, and with which is also combined a simple and effective means for holding the steel wedge from working upwardly and out from between the adjacent railends. a a a With other minor objects in view that will appear in the following detailed decha1r,specifically pointed out in the appended claims and illustrated in the accom panying drawings, in which t Figure 1 is a erspective view of my 1m proved construction of rail chair.

'Fig. 2 is a horizontal section thereof i taken particularly on theline 2-2 of Fig. 3.

Fig. 3 is a cross section taken on the line 3&3 on Fig. 2. W

- Fig; 4 is a perspective view of the steel Wedge member h reinafter specifically redarned-to. i 4 1 Specification of Letters Patent. Patented S t. 13 1921 Application filed June 14, 1921.

Serial No. 477,596.

Fig. is a detail horizontal section taken on the line 5-5 of Fig. 3. i

In the present development of my inven' tion, the chair 2 is reduced to about 8 inches 1 tioned singlespike 5. The chair 2, in my present structure, has the opposite upwardly extending parallelly disposed webs QL-Q whose inner faces, as in my patented chair, lie in parallel planes, but are not parallel with the central longitudinal plane of the chair, as a whole, but lie at an angle thereto,

to form wedge faces for cooperating with the wooden tapered keysor wedge blocks 3-3 whose inner opposing faces are parallel with and engage the web of the rail,"

as is clearly shown in the drawing.

The base 2 of the chair is chambered as at 2", as stated, to conform to and receive the rail face 1, and the wooden bed plate 4 on which the rail ends rest, the several parts being substantially the same as the like endsshown in my patent referred to. Instead of corrugating the inner faces of the wedge block 3, as in my patented construction, four V shaped grooves 6 are pro-u vided, one of said grooves Gbeing formed in the inner face of each end of each of the vertical webs 2 of the chair2 and into each ofthese notches or grooves 6, after the several parts that constitute my im proved rail chair have been operatively assembled, is driven a steel tapered pin 60, which issquare in cross section, and which pins eat their way into the wooden wedges as they are driven in and they serve to firmly hold the wedges from creepingendwise from their rail wedging position. scriptionzofmy present constructionof rail For further holding the several parts to their firmly clamped position, a thin steel wedge plate 8 is employed, and it has sub-w stantially the cross sectional T shape of the head, and the web of the rail, the head portion of the said plate 8 being, however, of a slightly greater depth than the head portion of the rail to thereby provide cars 81 that project below or under the flange edges of the rail head (see Figs. 1 and 3) the web portion 82 of the plate 8 being also of a slightly greater width than the rail weband somewhattapering to thereby cause the laterally projected edges of the plate 8 to penetrate into the Opposite wooden wedges 3 as the said steel wedge 8 1s driven home and there- 60 are"driven into the grooves 6, and the lower opposite ends of the head portion of the wedge constitute ears 81, each of which is apertured and projects below the opposite under face of the rail head, as shown in Fig. '3. a

"The-ears 81 of the plate 8 receive cotter or s lit ins 9 which 0 throu h their re- 21 t) sp'ective ape'rtures and fit under the flanges of the head of therail'and thereby prevent the; wedge plate 8 from working loose and being readily 'removed from between the rail ends.

- By roviding this steel wedge adapted to be driven between the adjacent ends of the two opposing rail members, a tight closure between the rail ends is-provided for, as'also a supplemental means for gripping into and holding the wooden wedge members 3-3,

- which means in connection with the key pin -*devices 60 at the outer ends'of the chair, and which engage the chair and the wedge blocks 3-3, produce a simple and effective means for holding the wedges to their driven position and does away with therelatively expensive clamp screw devices necessary in my patented construction and WlllCll, 1n praesticei'workloose andbecome'deta ched from :the railchair by the jarring produced by thepassing train.v In my present construction, the means for holding the wedges tightly up to their rail clamping position a will not readily becomeloosened or thrown out of operative connection with the rail and the wedges or pin fasteners, as the steel 'wedge' operates to positively maintain the said wedge inits proper operative condition irrespective of any jars or shocks incident .1 durmg the passing'of trains thereover. From the foregoing description taken in connection with the drawing, the complete :constructi-on, thelm'anner of its use and the advantages'of: my present invention will be readily: apparent tothose familiar with railway appliances o'f'the kind to which my inavention relatesi rf 1 a '"What l cljaim 'isz k 7 1. A rail joint comprising in combinatlon,

- a base'adapted' for being spiked onto a tie,

the-said base having a seat, apair of opposinn railendswho'sebase portions are re- 'ceived inthe chair seat, the chair having parallellyi extending webs 'held in planes at fan angleio'their opposing rail web face,

wooden wedg'efl keys interposed between the chair' andr'ail web races, the opposite inner ends "ofeach ehai-r' web face having a V shaped vertically extending groove and key pins square incross section adapted for being driven into the said V shaped groove and topenetrate the wooden wedges and thereby lock them from displacement.
