ADOLPHU'S Y. CLARK, OF SHORT CREEK, ARIZONA, ASSIG-NOR T SAFETY FIRST METAL TIE comrm, or SALT ILAKE crrY, UTAH.

i RAILWAY-TIE.

To all whom it may concern. 7

Be it known that I, ADOLPHUS Y. CLARK,

. of Short Creek,'in the county of Mohave and State of Arizona, have invented certain new and useful Improvements in Railway- Ties; and I do hereby declare the following to be a full, clear,cand exact description of the same, reference being had to the accompanying drawings, forming part of this specification, and to the figures and letters of reference marked thereon.

This invention relates to railway ties in which the body of the tie is made of metal and the direct supports for the rails are small cushion blocks of wood or like material, thus securing all the advantages of a timber tie with the employment of a small quantity of wood. The advantages are the 1 sound-deadening effect and elastic support ofthe rails the ability to secure the rails in place with the ordinary spikes and the insulation of the rails so as to 'render'them capable of use in the ordinary signalingsystems employing track circuits.

The object of'the present invention is to I lock the cushion blocks in the tie body in such amanner as to greatlyreduce the quantity of metal material necessary for the construction of the tie body,

In the accompanying drawings:

Figure 1 is a perspective view ofa tie embodyingthe present invention,

Fig. 2 is a similar view of the locking elements-shown in Fig. 1, removed from the tie body.

Figs. 3 and 4: are like views showing modified forms oflocking elements.

As illustrated in the drawings, the body of the tie is formed of sheet metal bent into substantially trough shape, 2'. 6., having vertical sides A and substantially fiat bottom A. A tie of this form possesses a certain inherent resiliency which will relieve the rolling stock from vibrations incident to a rigid bed. 'I-Iowever, to increase this effect the rails are supported on cushion blocks B instead of being supported directly on the metal portions of the tie. The cushion blocks B are fitted in the trough-like body in proper position to receive the rails and are of such length as will afford sufficient strength to support the rails and retain the Specification of'Letters Patent. P t t t 1 1 Application filed January 26, 1920. Serial No. 354,126. i

wood and as shown in Figs. 1 and 2 they are held in the tie against vertical displacement by shoulders 0 formed by turning down the upper edges of locking members C which are positioned in the trough-like body against the ends of the blocks.

To prevent vertical displacement of the locking members C, said members are provided with lateral extensionsc which fit in the longitudinally disposed receiving ends of bayonet slots 0 formed in the sides A of the tie body.- Y

1 In the modification shown in Figs. 3 and 4, the cushion blocks are held against vertical displacement at one end by. locking members such as shown in Figs. 1'and'2,but the locking membersD used atxthe other ends of; the blocks are. formed by a, strip of metal struck up from the bottom A of the trough shaped body, the strip ofmetal bemg sufiiciently long to permit its upper end 03 being bent down over the top of the block.

In Fig. 3 the locking member is shown as cut out of the central portion of the tie body a lateral'extensions eslotted as at 0'; These slotted extensions fit in the receiving ends of the bayonet slots 0 and overthe sides A of the tie body, and when the several parts are assembled, the extensions 0 on the locking members are forced well into the receiving ends of the bayonet slots so that the locking members and consequently the cushion blocks are securely held down in the trough-like body. In both forms of the device it will be seen that the locking members alone serve to hold the cushion blocks against 'movement longitudinally of the tie in one direction as well as to hold them against vertical displacement.

If desired, the transverse plates and the adjacent locking members may be provided with apertures F, F for fasteners, such as screws or nails, to retain the plates, locklocking members and transverse plates for locking the Cushion blocks against longitudinal and vertical movement renders it possible to form the tie body from a comparatively small sheet ofmetal, it only being a necessary that thesides of the tie body extend up alongside of the cushion blocks short distance. This, of'course, greatly re-.

duces the cost of manufacture of ties-of'th-istype.

What is: claimed is: p 11 A; railway tie embodying ametal trough-like body'having relatively low sides, a cushion block seated in the trough-like body and projecting above the sides of said body throughout its length to form'a rail seat, locking members positioned interme-' diate the sides of said bodyandengaging the topvof'the' cushion block for preventingvertical displacement of said block, and" a- V transverse holding plate positioned against one of'the lockingimemb'ers and having lat eral extensions interlocking with i the sides I ofthe trough-like body to prevent relative longitudinal movement ofthe cushion block andbody.

2. A- railway tie embodying a metal trough-like body, a cu'shion block seated in the trouglwlike body and'projectin'g above the sides of said'body to forma rail seat,

locking memberspositioned against the ends of said-block and having their upper ends turned d0wn"overthe top offsaid block, and

a transverse holding plate positionedagainst one of'th'elocking members and having lateralextensions interlockiflgwith the sides 7 of the trough-likebodyfto prevent relative longitudinal movement" of the cushion block and body."

3. A railway tie embodying a metal trough-like body, a cushiomb'lock seated-in the trough-like body and projecting above the sides o-fsaid body to form a rail seat, a

locking member engaging one end and the top of the block to hold said block against a longitudinal movement relatively to the trough like body in one direction and against vertical displacement, a second looking member engaging the opposite end and 'top of" the block, andmeans interlocking with the sides-0f the trough-like body to prevent relative lo-ngitudina lmovement of the block and body:

4:. A'railway tie embodying a= trough-like body having oppositely disposed I bayonet slots in itssides, a-cushion bloek seat'ed irr:

the trough-like body and projecting at the top ofthe-body to forma'rail seat,a loclringmember engaging one end and the top of the block to hold said block-against longi tudinal movement relatively: to the trough body in one direction and againstvertical V displacement, a second lock-ing member en gaging the'opposite end and top of the block and h avinglateral extensions fitting-in the receiving ends of'said bayonet slots,'-and a" transverse holding plate'hav1ng=lateral ex= tensions fitting in the entry" ends: of said} bayonet slots whereby said holding platewill be interlocked with the sides" of the 7 trough body toprevent relative longitudinal movement ofthe block 'and' body.

5, k railway tie embodying a trough-like- 7 body having oppositely disposed bayonetslots in its sides', cush iorrblooks seatedin the trough-like body and proj ecting" at I the top of said body to form: rail-seats; locking members engaging the ends and tops of the" blocks and having lateral extensionsfittingin the receiving ends of the 'bayonet 'slots,'-

and transverse holding plates having lateral extensions fitting in the bayonet slots, whereby said holding plates willbe inter locked with the sides of the body to prevent relative'longitu'dinal "movement of the cush ion block and body.
