RAILWAY-TRACK STRUCTURE.
To ctlwhom). it may concern,.-
Be it known that I, GEORGE M. ERVIN, of Johnstown, in the county of Cambria and State of Pennsylvania, have invented a new and useful Improvement in Railway-Track wherein a base or sup orting portion carries asurface plate of har er metal.
My invention is designed to provide simple means for supporting and securing these surface plates to the supporting-body and is applicable to various s ecific structures wherever vthe surface p ate is of considerable length, such as mates, ton rie-switches, connecting-arms of crossings, s ot work,and separable tread-rails.
The invention will be better understood by reference to the accompanying drawings, in which- Figure 1 is a plan view of a switch mate embodying-my invention; Figs. 2, 3, and 4, sections taken, respectively, on the lines 2 2, 3 3, and .4 4 of Fig. vl; Fig. 5, a plan view of a crossing also embodying the invention; and Figs. 6 and 7, sections taken on the lines 6 6 and 7 7, respectively, of Fig. 5. Fig. 8 is a detail view of a fastening, taken on the lines 8 8 of Figs. land Referring'iirst to the mate, (shown in Figs. 1 to 4, inclusive,') the letters A A A2 deslgnate the connecting rail members of the ortion, which is in the present instance an integral steel casting. "lhe end portions of this casting are cored out to form pockets, in which the said members are seated and surrounded by" a metal filling a, introduced in a molten state, this part of the construction being in accordance with my Patent No. 784,7 35, dated March 14, -1905, 'to which reference may be had.
C designates the hard-metal surface plate, on which are formed the track-surfaces, including the guard for connecting the rail A with the rails A AZ and whose ends directly abut the ends of the heads of all these rails, so that the car-wheels pass directly from the rails to the plate without the intervention of Speccaton ofwLetters Patent. Appiicaaonfiidzrunee,1905. seralNo. 264,024.
Patented oct. '50, 1906.
i any partof the casting B.' Said casting is formed .at one side with the upwardly-ex.- tending-iiange b, forming oneV side oa-pocket for th'e y plate C. The opposite side of the casting has its flange b cut off at a lower level and undercut to form the li b2, toward and underneath which the sai pocket is dee ened, as shown at b3. Formed on the un er side of the late C is a longitudinallyextending hook Fange or lip c, which .is shaped to loosely engage or interit with the lip b2, as clearly shown in Fig. 3, s ace being preferably left at this point, as wel as underneath and at the opposite side of the plate, for a filling and bedding d, of spelter or like material. The iange b is recessed. at b4 to form seats for plate-securing keys. These keys may be of any character capable of being released from the surface of the structure. I prefer to use those shown in my Patent No. 729,049, dated,
May 26, 1903, and indicated in Fig. 8, the divided keys being marked H. The bottoms of the plate and of its pocket and also the parts b2 and c are curved, so that when the fastening-keys are removed the plate can be readily removed from its seat by a plying a lifting or prying device to its straig t side at the key-seats.
It will be readily seen that by reason ofthe curved sha e of the interitting parts above described t e plate C will move readily under a prying action on the interposed layer of spelter, which will thus offer no resistance to its removal.
Figs. 5, 6, and 7 show a surface plate E applied to the connecting-arm F of a crossing between the usual intersection-plates G. Said plate E may be a separable plece, or it may be cast inte rally with one or both of the plates G. T e manner in which this plate is seated on the arm F is in all respects similar to that shown on Sheet 1, and corresponding parts are indicated by corresponding reference characters.
The sectional views shown by Figs. 2 and 6 may also be taken to represent the invention jIoo as applied generally to removable tread-rails.
I claim as new, and desire to secure by Letters Patent, isn
l. A railway-track structure having a base portion provided With a pocket, and a removable surface portion seated in said pocket, said portions having interfitting hook members, the bottom of the surfac-eportion and the bottom wall of the pocket being curved. 2. In a railway-track structure, the combination with a base portion having a raised pooket-formin flange at one side, and a depressed hooke flange or lip at the opposite sidegof a removable surface ortion having a hooked flange engaging the hooked flange of the base portion, the bottom of the surface portion and the bottom Wall of its seat being curved.
3. In a railway-track structure, a body portion, and a removable surface portion, said portions having intertting hooks at one side, removable securing means at the opposite side, and the surface portion having a curved bottom bearing.
In testimony whereof I have aliixed my signature in presence of two witnesses.
GEORGE M. ERVIN.
