An object of the invention is to provide a novel formation of tie, with which specially designed rail fastening'means coact, to prevent lateral thrustof the rails, even should undue pressure be exerted thereon.

Another object of the invention isy to associate 'a reinforcing medium with the tie, 'inl order to reinforce themetallic tie structure or casing, and-to hold the cushioning elements fr om displacement.` Other vobjects as well as the nature, characteristic features and scope of m invention will be more readily understoo from the following description taken in connection with the accompanying-drawings and pointed out in the claimsV forming a part of this specification. Referring to the drawings: Figure 1 is a of atie constructed in accordance with my invention, illustrating the Aapplication thereof, Fig. 2 is a top plan view of a pair ofties constructed in accord ance with my invention, and illustrating the application' thereof, Fig. 3 lls a'loiigitudinal Sectional view taken on the line 3-3 of Fig.

Portions of the reinforcing coinposition '.5 are removed, to provide recesses' G. Ears 7 are formed by extending the in# ner face of each side of the tie,above said openingsv for a. purposeinore fully hereinafterv described.

Detachably mounted lin the shell or casv ing 2 and in proximity to the vOpposite ends of the latter are rail fastening means.8each of the latter in the present instance comprisy laterally therefrom for engagement with the base Harige of the raill. t The fastening means 8 are arrangedv'in such close Vproximity; to the-lateral margins'vof the shell 'or casing 2, that it is necessary to provide reinforcing ribs 11 on the casing, in order to prevent casual displacement of said means'` should undue pressure be exerted thereon.

lBoth of the threaded Shanks 9 depend-into corresponding recesses 12 in' the Opposite lateral margins of the casing 2, wherebyv ac cess is gained to a nut 13-on each of1said threaded Shanks 9, thereby positively locking said fastening means-from displacement.

Reinforcing blocks 14 are mounted in the Opposite ends'of the shell 2, in-thepresent instance being preferably made of wood, in view of their inherentshoclr absorbing characteristics, likewise in view of their inexpensive nature. Theblocks 14 are/arranged siibjacent the openings 3 `'in the to of the shell and are provided with recesses i'n their upper faces, so as to receive the base lianges of the rails 1, said anges being thereby arranged below the upper plane of the tie, so as to minimize the possibility of lateral movement of therail. The inner terminals of' the cushioning block 14 abut 1the plastic ice order to expedite removal of the same Should tlieybe'renclered wornunsuitable for use. f -s `previously stated, the fasteningmeans are utilizedl'for preventing lateral thrust of thev rails 1 toward the'op'positeends of the Shell 0r casing 2, while lateraijtln'ust of the ra'ils in a Cou'ntertlirection is precluded in view of rail fastening' means generally designated 15. Th means 15 embodies a gravity atch member 1G,l one end of which has a portion'theieof removed, to conform to the contour of the base flange of'the rail, and adapted for engagement with the latter. Theopposite end ofv the gravity latch 16 is pivotally' connected to one end of a bolt 17, the opposite end being screw-threzuled and ergagedfthiough nn ear` 7 in the upper face ofjtlie easing 2, nsadvantageously illustrated inf Fig. 3. A` nut 1,8 is threadecl'on each of the bolts 17, vhereby the latterare movable a vertical; plane irrthe casing, so as to actuate the gravity latch 1G into engagement wtliffo'r outA of@ engagement from the base flange ofthe rail, I; "A bracing rib 19 is del-st hat the vills ljare first arranged ing'fbl'ocks "1 4, after which stt ""i-lans 3 are snugly en-v tpigedfw at the i aange f am 4ma, by aa, exertion' of'p'ie." ure iipori the nuts 13.

rat-ion' therefore, itis of course, un-` ment with the base flanges with which the rails 1 on the opposite side from that of the means 8 engage. thereby precluding possibility of the rails being laterally thrust in either direction. When it is desired to remove the rails from the shell or casing 2, the nuts 13 and 1S are, of course, removed from their respective bolts, .to permit. removal of the rail-fastening means, `and disengagement of the-.platches 16. A suitable instrument may then be inserteil beneath the rail 1, through the openings 3 in the top 'of the shell, when itv is`desired tovraise the rail out of engagement with the casing. .It will be understood thatthe .abovevdescription and accompanying drawings comprehendonly the general and preferred embodiment of my invention and that various minor changes inzdetails of construction, proportion and arrangement of' parts, may be made within the scope of the appended claims without sacrificimgT any of the advantages of myinvention.

Having thus fully described my invention what I claim as new and desire to Letters Patent-is:

1. A rail fastening means including the combination, with a tie structure, of means mounted therein and engaging tme'side of theI base flange of-afrail to hold the latter from displacement iriaone direction, a floating clamping bar positioned in said tie and having a working;r ,end engagedavith the posite side of Said base fiauge, member within said tie, said floating clamping secure by a stationary the opposite end'of bar being,l engaged with said stationary member, and nuans connected with .said fioating clamping bar for adjusting the latter tionary member and Saidraih 2, A rail `fastening,r means including. the combination withla tie structure, of means between said sta' mounted on the tie for engagement with one side of a rail base flange, an inclined statlonary memberwlthln sald tie, a clamping;r

bar engaged with said imfli'ned stationary member and lhai/'ing a workingend enfaged with the opposite sideof the base dange, 'means to preventupward movement of the working end of said clamping bar, and means pivoted .to said tighten the latter flange.
