@o all whom 'it may concern:

"Be it known that I, JOHN G. SNYDER, a citizen oi the United` States, residing at Altoona., in the county of Blair and Stateof Pennsylvania, have invented nertain n'ew and*v useful Improvements in Metallic 'Railway-Ties, of which the following is aspecification.

The invention lrelates to improve'mehtsin metal railway ties and it has for` its object the 'provisionof such a devine that will not only have suiiicient stability to withstand the wear and tear of'tradic, .but which will .also have'suflicient elasticity@ to givelthe rails the resilient support necessary 'to' movement of the rolling-stock. i'.

It also has foiits object .the provision oi means for' adjusting the clamps so that the railcan be easily posi tioned and secured in place.

The inventionconsists in the novel construction,

. combination and arrangement of parts, such as will'be hereinafter fully described, pointed out in .the-Jappended claims, and illustrated in the accompanying In the drawings, in which similar reference charac-y ters designate' corresponding parte, Figure 1 is a per-- spective view of a tie embodying the invention. 2 is a plan view of the casing or shell forming the tie with the rails and clamps removed. Fig. 3 is a longi tudinal sectional view of one end of the tie with the' rail and clamp in position. Fig. 4 is a cross sectional Vview showing the shell and elastic filling. 5, 7 and 9 are, respectively, plan, end, and side 'views'of the clamp. Figs. 6, 8, and 10, are, respectively, plan, end, and side views f a modified form of the clamp. Fig. 1l, isan enlarged detail perspective view showing the bolt.A

The tie is formed of a casing or shell of 'sheet steel or other suitable metal and Vin general shape and dimen-v sions resembles the ordinary wooden tie. It has the dat upper surface or crown 1 and the rounded sides 2,' ,and it is open atboth ends .and at lthe bottom. The edges of the sides," as at 3, are curved inwardly and upwardly to form semi-elliptical springs, on the rounded part of which the tie rests. These springs, together'` with the curved sides, give to the tie the required elasticity to meet the tratlc conditions of the road. In the casing is the elastic 11ing`4 of such a nature as to give to the tie the stability required `and also which will permit the tie to yield to take up the shock of the pasing load. The filling is preferably comprised of a mixture of asphalt, bitumen and liber, which latter' may be either mineral or vegetable. The asphalt and' .bitumen give the required body and cohesion to the lilling andthe fiber acts as a binder to hold the mass' together. The fiber also serves to render the elastic so that it can yieldtb the movement of the tie form springs, but also serve hold the lling within the easing. Owing to their-formation the inwardly l under the stress oi a load. The edges not only 5 turned edges 3 cannot spread apart under.' the weight of a passing load, but will" have atendency to move inwardly, which would be opposed by the filling.

Owing to their formation, the inwardly and upwardly turned edges 3 of the tie penetrate the material of the road-bed to a considerable extent; also the compara tively wide opening in the bottom of the tie ,permits road-bed material to enter the tie and adhere to the filling. In this way the tie is held against movement.

The rails are heldin place on the tie by the clamps 5. Each clamp at its inner end is shaped to fit the baseand web of the rail and to abut against the under side ofthe crown. Inthe outer end of the clamp is the obli-(jue slot 6 throgh which passes the bolt 7 mounted 'in the tie. When the bolt is placed in`position its head is inserted in the opening 8 in the tie and its shank, v

which is flattened, as at 9, is moved into the recess 10 extending towards the'rail. When in this position the head of the bolt projects beneath` the edges of the tie andis thereby held in place. By means of the oblique .slot 6 theclamp can be moved from one side to the `other to move it toward or from the rail so that a proper adjustment of the rail and the tie can be secured. The

flattened 'part 9 of the bolt prevents the turning oi the latter when the nut is applied. The purpose of the bolt is to hold the clamp down upon the/tie.

Longitudinal movement of the-clamp 5 is prevented by the lugs 11 which project from the under side of the outer end of the clamp at its corners. `These lugs are adapted to register with the slots 12 in the tie. The

slots are parallel with the longitudinal axis of the tie.

the latter is in place. Consequently the ends of the slots .approach and recede from the rail by very shallow steps. By moving the clamp from one side to the other a very close adjustment relative tothe railcan be secured. When the clamp is in position the lugs engaging with the slots hold the clamp against the end thrust exerted by the rail. The bolt; when it is secured, holds the clamp in place and also holds the rail 'down on the tie. By loosening the bolt theclamp can be very easily moved from one 'side to the other tosecure a vchange in the adjustment. l 'In the modificationv shown in Figs.,6, 8 a'nd los iongitudinaliyhnd then transversei'y so that thestrips of metal can be turned down to form the lugs inside of the edges of the clamp. The clamp iti this instance is adjusted in the saine way as in the formerinstanee. Other modifications of the -deviee are obvious. l

Having thus described my invention what Incl-:Juin

and desire to secure by Letters Patent is:

1. A metallic railway tie comprising :l casing 0l: shell open atthe bottoni with the edges of the sides turned inwardly and upwardly to form springs, and means for securingthe ruil to said tie. l

2. A metallic railway tievcomprising; a ensingor shell open ut the Bottom with the edges of the sides turned inwardly und upwardly to form springs, an eiustie filling for the easing, und ineens for securing the ralil to Athe tie'.

3. A metallic railway tie comprising;l .ft easing or shell provided with :1 plurality of slots parallel with the longi- `saisie?" tndinai axis of the tie and said slots arranged so that their ends meet u line extending,l obliquely around the tie, und n mii-clamp provided with lugs' adapted' to register with said sluts. Y

4. A metalle railway tie comprising a casing; or shell 'provided with :l plurality of pnruliel siots extendim,r iong'hl tndnnlly of the tie and arranged to extend obliqnely around'the tie, :i rail-clamp having; lugs adapted to register with Said slots and `provided with n groove extending parallel with the oblique line running through tlleends of salid slots, and n holt mounted in said casing und engaging with sslid groove in thc rnil chimp,
