Be it known that'I, RICHARD L. POWELL; a citizen of the United statesjresidin'g at Lewistown, in the county of Mifilin and State of Pennsylvania; have invented a new and hsefulSlf-Cushiohihg Metal Tie, of which the following is a specification;

The device. forming the subject matter of this application is railroad tie, and one object oi the invention is to provide novel means whereby the tie will have the desired resiliency. 7 Another object of the invention is to ro-f vide novel means for connecting a ml to the tie; V

' It is within the province of the disclosure to improve generally a'I-ld to enhance the utility of devices of that sort to which the invention appertai-ns. i

With the above and other objects in 'i iew which will appear as the description pro-- ceeds, the invention resides in the combine tion and arrangement of parts and in the details of construction hereinafter described and claimed; it being understood that; changes in the precise embodiment of thein vention herein disclosed, may made within the scope of what is claimed, without departing from the spiritof the invention.

In the accompanying drawings Figure 1 shows in top plan, a device constructed in accordance with the invention; Figure 2 is a longitudinal section; Figure 3 is a transverse section; Figure 4: is a plan of one of the rack bars Figure 5 is a perspective view of one of the cushion plates; and Figure 6 is a fragmental section.

in carrying out the invention, there is provided a metal tie 1, which may be described, roughly and generally, as being of inverted trough-shape. The tie 1 comprises a top 2 and side walls 3 equipped at their lower edges with inwardly extended flanges The top 2 of the tie has a trough-shaped longitudinal seat 5. In the base of the seat 5 there are key hole slots 6. An opening 7 is formed in the base of the seat 5 and is disposed between the key hole slots 6. In the side walls 8 of the tie 1 there are elongated openings 8. The openings 8 are enlarged at their ends, as shown at 9.

In the sides 3 of the tie 1 openings 10 are formed. The openings 10 are located, respectively, above and below the elongated openings or slots 8 and communicate therewith. In the openings 10 are located plates The endsnf the sideflangesv 12 engage the 11,-the plates ll' having side 12;

The:flanges 12 on the plates-11 prevent the block 16 "from in'ovingilengthwiseofthe tie'l, as Figure-2 will in-akefiinaiiifest. A securing element 1?, snich a'spike, is drii'enfdownwardly through the uppermost: plate 11, into the block 16, to hold the block against shifting transtersely of the tie "The opening 7 in the-seat '5 of the tie 1 permits the driringof the securing elementor spike 17 Arack bar fits closely ,nrthe .s'eat Fibf the tie '1".

The projection 20 ex'erc'ise's two functions Fir-shit aids in preventing the rack "bar 18 ltronr shitting eii chvise. Second, it siert'e-s to hold downithe securing element or spike 171 The rack bar 18 has key hole slots 21 which register with the key hole slots 6 on the tie 1. The rack bar 18 has depending fingers 22 which, engaging the tie 1 at the outer ends of thekey hole slots 6, aid in preventing the rack bar 18 from moving endwise.

The rail 23 rests on the top 2 of the tie. Retainers 24 are supplied, and are adjustable in the seat 5 of thetie 1. The retainers 24: have racks 25 cooperating with the racks 19 of the rack bar 18. Securing devices 26, such as bolts, are adjustable in the registering key hole slots 6 and 21 of the tie and of the rack bar, respectively, the bolts 26 passing upwardly through the retainers 21-. The head of each bolt 26 comprises a part 27 which fits in the restricted part of the key hole slots 6 of the tie l, to hold the bolt against rotation. The head of the bolt 26 includes, also, a laterally extended part 28, engaging the undersurface of the base of the seat 5, on each side of the restricted portion of the key hole slot 6. Nuts 29 are threadedon the upper ends of the bolts and engage the retainers 24.

tratfic conditions.

The tie forming the subject matter of this application is so constructed that it affords a simple but efficient means for holding the rail 23 in place, the tie having the necessary resiliency and thereby avoiding one of the main objections to metal ties, namely, their extreme rigidity.

The tie forming the subject matter of this application may be alluded to properly as a self-cushioning metal tie. Its construe tion is such that it will of necessity give a uniform cushion at all times, regardless oi": Especial attention is di' rooted to the fact that practically all of the fastening means are located well down in the trough-shaped seat 5, and, consequently, there is small chance that the mechanism alluded to will be broken or damaged by the wheels of cars, or in any other way. Furthermore, when the track gets out of line, the rails may be moved, to secure alinement, with respect to the tie, it being unnecessary to throw the tie, along with the rails, and

move the tie on the ballast, after the ballast has been tamped to a firm bed under the tie.

Having thus described the invention, what is claimed is securing element being insertible through the opening, a rack bar on the tie and having a projection received in the opening and located above the securing element, a rail retainer cooperating with the rack bar, and

- means for holding the retainer in place.

2. In a device of the class described, a tie provided in its top with an elongated trough-sl'iaped seat, a rack bar in the seat, means for connecting the rack bar to the tie to prevent the bar from shifting in the seat, a rail retainer extended into the seat and cooperating with the rack bar, and means for holding the retainer in place.

3. In a device of the class described, a tie provided with elongated slots in its sides, plates extended between the sides of the tie. a cushion block located between the plates, the slots extending on both sides of the cushion block, and means for holding a rail on the tie.

4:. In a device of the class described, a tie provided in its top with a trough-shaped seat, a-rack bar located in the seat, the rack bar and the seat being provided with registering key hole slots, a retainer coacting with the rack bar, and a securing device connected with the retainer, the securing device comprising a head engaged beneath the seat and insertible through the enlarged portion of the key hole slot, the retainer comprising a part fitting in the reduced portion of the key hole slot of the seat to hold the securing devices against rotation.

5. In a device of the class described, a tie, a rack bar on the tie, the rack bar and the tie having registering key hole slots, the rack bar having means for engaging the tie at the ends of the key hole slots of the tie to prevent the rack bar from shifting, a rail retainer cooperating with the rack bar, and a securing element adjustable longitudinallv in the key hole slot and connecting the retainer with the tie.

In testimony that I claim the foregoing as my own, I have hereto afiixed my, signature.

RICHARD L. POWELL.
