escawBe itknown that I; JOHN S. SCHAEFFER, aeltizen of the United States of America, residing at Phoenix in the county of Oswego and. Sta-te'of New York, have invented certain new and useful Improvements in Cross- Ties; of which the following is a-speeification.

. This invention relates to railway tracks and particularly to cross ties and rail fasteners the'refor.

-An object of comprising preferably metal and a composition in which the metal is'embedded and the metal is preferably hollow and filled with concrete so that the concrete acts as a filler and anenvelop' for a metal shell.

A further object of the invention is to provide a'hollow metal core for a railway tie. the said core bein formed of a series of platessecured toget ier, the said plates being Wrapped With Wire or the like'for' the purpose of retaining them in assembled relation to'increase thevstrength of the tie. the said m'etal'shell thus formed being embedded in concrete and preferably having a concrete filler..

A furtherobject of the invention is to provide a tie having a body as indicated above, the shell heretofore referred, to having openings therein to receive the rail anchoring devices, and the rail anchoring device comprising clamping members suitably anchored with respect to the cross tie.

A still further object of the invention is to provide a crossltie having a rail securing device'in which bolts are used for holding the rails in place'or in which substitutes for.

bolts may beutilized in the shape of the ordinary -spike, and the invention further contemplates the provision of a'serrated spike and a'wooden anchorage for the spikes suitably held in the prismoidal holder.

' still further object ofthis invention is tln n-ovision of a novel cushion so positioned witlrrelatiou to rail seeming devices that the said cushion is held inplace against movement by the said rail securing devices, and-' the' invention further consists in the novel clamps acting in conjunction with the tie plates and the means for holding the relation: 7

With the view, the invention consists in the details of cushion, tie plates and clamps in assembled foregoing and othenobjects in Specification of Letters Patent.

"The cross tie isprei'cralily formed by utilizing metal and concrete and the metal. portion of the tie is preferably in the form of a shell A, comprising twoor more sections, the outer surfaces of the ,SGCUODS of the shell being grooved transversely and longltudi- The upper and lower walls of the shellare provided with apertures 6, adapted to receive a yoke (hereinafter referred to) for fastening the rails to the cross ties and these yokes are preferably applied to the apertures of the shell priorvto the application of the concrete to the shell. In constructing or first assembled and wrapped after which the said find its way to the interior of the shell and i side of the rail opposite to that engaged by the clamp L. The tie plates are, as stated, two in number one of which is made a right hand, and the other a lefthand in order to remove them without displacing the track 01- disturbing the tie, this being true as to the renewing of the bolts.

forming the tie the sections of the shell are shell is placed in a molding box which is tilled with concrete so that the concrete I In the form shown in Fig. 6, the cushion is provided, on which the tie plate It, rests and the said tie plate supports the rail h, the flanges of the rail being secured by clamps T, quite similar in construction to the molding box is of such size as to permit i the clamps L, heretofore described, although the shell to be coated on its whole external the external coating need not be very thick. I he rail fastening device is applied to the tie in position to receive the rails and said yokes compr se prisms, formed in two halves, one half being shown as comprising the sections G, I), connected and the two sections of each half of a prism have ears to receive the rods or bolts E, F, by which the two halves of the prism are joined. The tops of the prisms are open, except for the covering afforded by the clamping are aperturcd to receive the bolts G. use of the tie plates and bolts, the said clamping plates are held against movement owing to the fact that the hollow prisms are embedded in the crosstie. -When the shell heretofore described has been applied to the mold box and the hollow prisms are placed in the openings of the shell, the concrete which is applied to the shellfills the spaces between the hollow prisms and by this means, the hollow prisms are anchored in the shell. The prisms are connected by horisontally disposed bars d and the space between the bars and the tops ofthe prisms is filledby a cushion I, and it is preferable that such cushion extendslightly beyond the tops of the prisms in order that the tie.

t they have a surface and I have found in practice that plates H, which clamping plates In the 5 t be found very late may I provide for securing therails in place and slightly difi'erent contour. In this form, the threaded ends of the bolts U, extend through the cushion, tie plate, and clamps and the nuts u, are applied thereto. for the purpose of binding the parts in posil tion. In utilizing the bolts as here shown, f it will be understood that the heads of said by a base plate, and being connected near their tops by a bar (Z,

bolts will lie against the bottoms of the said prisms and the shanks of said bolts will extend through the apertures in said bottoms tengaging the base'fianges of the rails are I integral with the upper section V, of the tie plate and are bent to overlie and retain the base flange in 'position.

In the form shown in Fig. 8, of the drawings, which is a transverse sectional view similar to the view shown in Fig. 3, the shell A, for the filler isprovided with outturned'portions 6, adapted to partially support the rail securing plates 6, the rail, in

this instance resting directly bn' the filler hnd being clamped firmly by means of bolts 6,

I as is clearly shown therein.

The tie plates which-I show in Fig. 2-, will desirable in practice as they be raised on the cushion, so that saitijljushion bracing them from opposite sides. In this may absorb the shock and vibration inci-' dent to the use of the rails which are supported by the tie plates.

The means for securing the bases of the rail and the tie plates may be variously modilied and for the purpose of illustrating some of the forms. that may be advantageously formed, I show in Fig. 4, a tie plate J, with rods K, for connecting the tie plates and the PIlSII'IIS and1 in tllls'fiilm 1 1the inventionMI em 0 a cam in ate iavin s urs ad pt d to be e mb edlied in the tie late and I alsdemploy bolts -.N, which exten through the apertures in the tie plate and as shown in this figure, the clamp overlies a portion of the base of the rail 0, and hence said rail is secured in place. In this, form, the tie pl which extends over the ase flange on the constrpction, there are two tie plates on each end ot the cross tie, and said he plates havingcin-ve'd lugs X, X, extending in o posite directions so that one tie plate Y, Will I pro ect on one side of the rail and be securedby a bolt Z, with the lug X, of said plate Y,

overlying the flange on ene side of the rail, whereas the plate Y, will project on the gp posite side of the rail and its curved lug will overlie the base flange of the rail on the side of the rail opposite to that engaged by the curved lug In connection "with the hollow prisms here; tofore described,'I may employ other fastenlates with curved lugs X, XI, applied.

a spike C, is driven. into the filler and anchored therein, the same as it would b'e-a'nchored in an ordinary wood tie. In this form, the cushion I, is employed in the same relation and for the samepnrposes as heretoforedescribed; I

In the form shown in. Fig. 11, a cushion E; is employed with 'atie plate 'F', and a hollow prism G, also employed having its internal wall rovided with shoulders ll, and the said s oulders are designed to be eiwaged by teeth You the shank of a I 's p'ike 3". The wall'o'f theip'rism opposite the shoulders H, is provided-with a series of shoulders K, deslgnedtobe engaged bya spring L','which springhas a curved end engaging the serrations M, on'the shank of the spike and as the said spike is'appli'ed i to the hollow prism with itshead engaging the base of a-i'ail N, the spring'will act to force theshank of the spike into engagement with the shoulders of the wall of the prism and by this means the spik'ewill be held against upward'moyement.

The form shown in Fig. 12, is somewhat analogousit'o thatshown in Fig. ll, except that in this. form, the hollow .prism 0, 1s,

provided with a. wood or composition filler l",- which is held in the prism by the roughened surface Q of'the prism and these'rrated spikeR, is driven into the filler and i anchored therein as fully illustrated insaid Fig.12.

' Figs. 9, and 10,- show another means for anchoring spikes and it consistsin a' hous-- f eounecte nitlulrawn from the housing until the spike strengthened to prevent bending of ing S,- adapted to receive two prismoidal ore blocks T and'U, respectively and the sa id blocks are connected b'ythe spike when it is driven. intothe said blocks. By reason of the fagt that the sections 'ofthecor are prismoidahthey can be assembled in the housing in SOCtlOHShlld then when they are removed. This anchoringmeans. may be substituted for the prisms and clamps heretofore described, as the housing may be applied to the shell of-the. cross tie before or at, lllCllll'lO the. shell is placed in the mold to receive the concrete;

'Two such rods are placed on each side of .the tie and the space inclosed by them is elliptical and as shown in this figure,

at the top to carry out the prismodial conchoring device.
