Be it known that I, THADDEUS SELLECK, of Greenwich, in the county of Fairfield, and State of Connecticut,

'have invented a new and improved Mode of Securing Railroad Rails to their Sleepers or Ties; and I do hereby 'declare that the followingis a full, clear, and exact description thereof, which .will enable others skilled lin the art to .make and use the same, reference being had to thev accompanying drawings, forming part of this specification, iuwhich- Figure 1 is a plan or top view of my invention.

This invention relates toa new and improved mode of securing railroad rails totheir sieepers or ties, and it has for its .object the avoiding of several diHiculties attending the ordinary F chairs, so termed, and other fastenin'gs hitherto devised for the same purpose. The principal diiculty attending the different means hitherto employed for securing therails to the sleepers or ties has been the expansion and contraction of the rails, and also the vertical play of the latter due to the passage'of the car-wheels over them, and which cause the ends of n the line :c x, g. 1.

the rails to be hammered or battered down under the action of the wheels. These difficulties, it is believed, are' fully obviated-by my invention. n

A represents the rails of a? portion ot' a tracli,tl.e abutting ends or joints of the rails being shown.v B are the sleepers or ties on which the rails rest and are secured. C C represent two metal plates, the edges of which are curved or bent upward -to form lips or iianges,.a a, between Awhich the bases of theI rails are fitted, the lips or langes bearing against the sides of the vbases or lower parts of the rails, as shown clearly in tig. 4. The adjoining or abutting endsot the rails A. are at the centres of theplates C C, and the latter are shown in` the present instance resting on two sleepers', B B, but they may rest on more than vtwo sleepers if long plates be used. The plates C40, whether resting upon two or more sleepersfare fitted snugly between the sleepers at their` ends, designated in tig. 1 by ax ax, so as to preclude any longitudinal play or movement of said plates;

andin order to admit of this the sleepers-en which the plates rest are rather lower than .those at their-ends designated by ax, or the first-mentioned sleepers may be notched out to receive the plates G C, the same end being attained in either case. On each platerGthere is placed a strip oi` sheet metal, I), one"or more, and the rails rest on these plates, whichrserve to prevent the rails being subjected to any material amount of concussion or hammering under the weight or Aaction of the car-wheels. The plates C C, andy consequently theA rails', are prevented from moving laterally by means of the ordinary spikes c, which are fitted in notches in the'anges, the heads of the spikes projecting over the upper edges of the iianges a a, and also overv the bases of the rails if desired. The rails are secured firmly in the plates C C, between the anges a a, by means of clamps D E E. The principal clamp D is atthe centre of the plates, and it is simply a wrought or rolled rectangular plate placed under the plates, curved upward at each end, and secured down upon the rails by means of a hammer or any suitable means. (Sefe'g. 4.) These clamps D are fitted between the sleepers on which the plates C C rest, and they are consequently prevented from moving in a longitudinal direction. The clamps EE are constructed precisely similar to D, but they do not encompass the ilanges a a of the plates C C, said flanges being cut out or notchedfso that'theiclamps E E will bearer press against the sides et' the bases of the rails. (See tig. 2.)

From the abovedescription it will be seen that the plates C C are secured to the sleepers by the spikes c, and longitudinal play or movement of said plates prevented by said spikes, and also by having their ends fitted between the sleepers a? ax, while the clamps D E securethe rails in or to the plates. It will further be seen that the rails are not cut or punched in any manner near their ends for bolts or spikes to pass through, as is usual in ordinary couplings, and consequently the rails are allowed to expand and contract freely in a longitu` dinal direction withoutaifecting in the least any parts of the fastening described. The rails are secured at their centres to the sleepers by twoeerewsor spikes, bx, but these will not interfere with the free expansion and contraction of the rails, owing to their position being a central one. The` rails nmy'also be secured to tbe sleepers by the ordina-ry spikes, the heads oi`-the latter fitting over the ba-rs of the rails, but not in notches made therein so as to interfere with the expansion and contraction of `the mils.

Ido not confine myself to any particular length furthe plates C C, nor to any number of clamps D E E, 1101` to any number of metal plates I) for the rails to rest upon ou plates C C. I claim as new, and desire to secure by Letters Patcntl In combination with the rails A A the flanged plate C, extending the distance of three er more intervals` of the ties, the clamp D extendirigl across the middle interval :1nd embracing the point of junction of the rails,

and the cnil clamps E E, all arranged substantially as herein described and represented.
