RAILWAY-TIE.

` Speeilication of Letters Patent.

` Application led June'20, 1912. Serial No. 704,851.

Ties, of which the following is a specicaf tion.

My invention relates to new .and useful improvements 1n rallway ties and more parmy invention' is to provide an improved V form of metallic tie of the type in which road in the same manner as .the usualY wooden rail supporting blocks are mounted and held against movement in a metal frame which is embedded in the ballast of the wooden tie. A further obect of my invention is to provide a meta tie in. which the central portion of the tie is open vertically to per mit the positioning of lthe crushed rock -or other ballast of a road bed and to more firmly bank the tie in place, this construction also giving a slight resiliency to the central portion ofV the tie rendering t-he same more serviceable and of reater value' in road beds where the ground 1s frozen during a portion 0f the year.

A further obiect of my invent-ion is to provide a metallic frame for holding the rail supporting blocks and a plurality of braces for the frame whichnot only. stiften the frame but also serve to lock the blocks against movement when the rails are in position thereon.

` A further object of.v my invention is to provide certain of the above mentioned braces with extended portions or flanges which engage against the outer portions of the rails to prevent the rails from s reading, this not only simplifying the aying of the track but also reducing the number of spikes employed in securing the rails in ositionand' therebyI avoiding the danger of splitting the rail supporting blocks, the

splitting of the blocks being a common occurrence in ties in which the sole securing means for the ralls consists of spikes driven into the blocks.

A further object of my invention is to so construct the rail engaging flanges of the braces as to adapt them for use in connection with fish plates in the formation of an extremely rigid and strong railjoint4 for securing the adjacent ends of rails together.

With these and other` objects in view, the invention will be more fully described, illustrated Ain the accompanying drawing, and then specifically pointed Vout in the claims which are attached to and form apart of this application. i

In .the drawing: Figure 1 is a perspective k,view of my improved tie, showingthe rails in place thereon 'and showin the employment of the' rail engaging anges lin Patented Feb. 25, 1913. I

connection with a fish #plate for forming a rail joint; Fig. 2 is a central longitudinal sectional view ofthe tie, the blocks being removed to more clearly show the construction of the tie proper; Fi 3 is a vertical transverse section on the l1ne 3 3 of Fig. y

2, more clearly bringin out the arrangement of certain of the braces, particularly the rail engaging braces.

Corresponding and like parts are'referred to in the following description land indicated in all the views of the drawing by the same reference characters.

As previously stated my improved tie is of that type in which a metallic frame. supports blocks of wood which form bearings for the rails and said tie includes block holding end members, side members or plates secured to the side portions ofthe ends members and maintain the same in proper spaced and alined position, base plates forming tie supporting members and extending beyond the ends of the tie roper,

braces stiffening the frame and also ocking the blocks in place, and additional braces for the frame arranged to engage theouter portions of the rails to lock the same against spreading movement on the tie.-

VReferring more specifically to the draw-4 ing, each tie includes a pair of spaced end members 10, each formed in a single iece and Ushaped in section, having a orizontal base web 11 and spaced side webs 12. Each of these members has its side Webs cut-away or otherwise shaped to. form u wardlyextended shoulders 13 at their endg, the function of which will be hereinafter explained. These end members form a seat for the wooden rail supporting blocks'14 and are secured together in proper spaced apart, alined .position by sideV members or plates 15, the end portions lof which are riveted to the side webs of the members 10,

'the heads of the rivets being preferably the close engagement of the rail supporting blocks by the block holding members.

Secured to the lower face of the horizon- 'tall web portions 11 of the end members are` base plates 17, the outer ends of which ex- -tend beyond the outer ends of the block holding members andthe inner ends of which extend, beyond the inner ends and y terminate in spaced relation as shown 1n Fig.' 2. These base plates are preferably of such a width as to not only extend` beneath the block holding members but to also extend by their side edges beneath the loweredges of the side plates 15 and said base plates are secured to the horizontal webs of the end members by rivets in the same manner as are the side plates.

The members thus far described constitutel the main body or frame ofthe tie, the other Aparts shown in the drawing and hereinafter described consisting chiefly of braces for strengthening the tie and securing the rail supporting blocks in place. The outer eX- tended ends of each of the base plates 17 are strengthened and reinforced by'leveling plates 18 equal in thickness to the thickness of the horizontal .web portions of the end members vand therefore leveling the Outeiends of the base plates therewith to form a support for the blocks should the latter extend slightly beyond the ends of the blockv holding members. lIn like manner, the end portions of the b-ase plates which extend inwardly beyondthe block holding members are strengthened and leveled by, similar plates 19, all of these leveling plates being secured to the base plates by rivets or other preferred means. These leveling plates 19 permit the insertion lof one of the blocks 14 in the central portion of the rail when necessary for the positioning of a frog or switch rail and the central portion of the frame between the adjacent ends of the block supporting members is preferably equal in length to the length of one of the blocksupporting members.

The side plates 15 of the frame are braced against inward movement toward each other by U-shaped braces20 which arel secured byA their side portions to the inner faces of the side members and which bear by their base .l portions against the inner edges of the block receiving members and consequently against `against upward movement, I have provided U-shaped braces 21, the body portions of which-extend across the inner ends of the cure the side plates yto the block holding members. Additional 4U-sliaped` braces 22 zare secured across the outer ends of each of the block holding members, the-side portions of these braces bearing against the outer faces of the shoulders 13 to which they are riveted, lwhile the body portion extendsJ transversely of the tie between said shoul. ders. These' braces 22 are provided at their inner sides with upwardly directed extensions or flanges 23 which bear over the outerl flanges of the rails when the latter are in place, the edges -of the rail fianges seating against the inner ends of the shoulders 13 and being thereby held against outward movement upon the tie.

Combined braces and rail engaging members 24 are mounted upon the body portions of the braces 22 and comprise U-shaped members,'the side portions 25 of which are riveted to theend portions of the side plates 15 and the body portions of which rest upon the body portions of the braces 22 and have extensions 26 bearing uponthe extensions 23 of the braces 22 and terminating in vertically directed fianges 27 which engage against the outer faces of fish plates carried by th'e rails and which are perforated as jsh'own atv 28 to receive bolts which pass through said fianges, the fish plates and rail to securethe rail in place.

In operation, the blocks are positioned in the block holding'members as shown in Fig. 1 and the tie is properly positioned and ba'llasted in the usual manner, ballast alsol being positioned between the-inner ends of 'the blocks and the side portions of the side members to additionally anchor the tie in place. The rails are then positioned upon the tie and moved to bring their outerflanges beneath theextensions 23 and 26 of the braces 22 and 24 and against the inner ends of the shouldersl.

In 1 I'h'ave shown conventional rails y 28 applied to the tie and fish plates 29 positioned upon either side of the rail webs,

the outer fish plate beingpositioned between the vertical web of the rail and the flange 27.

Bolts 30 are passed through the perforations of these flanges, through the fish plates and through the vertical rail webs and are secured in place by nuts 31. l

It will of course be understood that the fish plates may be done away with if desired and the braces which engage the rail proportioned and arranged to engage directly against the vertical web of the rail. When so employed, the flanged portion 27 of the brace 24 will take the place of la fish plate at a rail joint and but one fish plate will be necessary, said plate being of course applied against the inner face of the rail web to co-act with the flange 27.

From the foregoing description, taken in connection with the drawing, it will be apparent that I have provided an extremely simple and eiiicient form of metallic tie and one in which the main frame of the tie is firmly braced by braces which also serve to hold the rail supporting blocks in position and to hold the rails against spreading movement upon the tie.

It will of course be understood that various changes in the details of construction, such as the omission of the leveling plates, or the extending of the horizontal web portions of the block holding members to take the place of the base plates, may be made if desired, without in the slightest degree departing from the spirit of my invention.

The outwardly extended ends `of the base plates is one of the important features of the invention in that it gives an added supporting area to the tie, thereby permitting the leaving'of the central portion of lthe tie open for ballast and also because the ballast may be banked against the ends of the tie and over said extended portions to further anchor the same in place.

The inner flanges of the rail are secured in place by the customary spikes 32 driven into the blocks 14 and it will be apparent that the blocks may be readily removed and renewed when decayed or otherwise unfit for useby the sim le Withdrawal of these spikes, the blocks eilig driven out of the ends of the tie by blows administered against their inner ends, thebraces 20 being ,so roportioned as to expose the inner ends o the blocks for this purpose.-

Having thus described the invention, what is claimed as new is:

l. A metallic tie including block receiving members, side members connecting said block receiving members, and base plates secured to said block receiving members and havingv their inner ends spaced apart and their outer ends extended beyond the outer ends of the block receiving members, said base members being equal in width to the block receiving members.

2. A metallic tie including block receiving end members, side members connecting the end members, base plates secured to the end members and extending at their ends beyond the same, braces extending between the side members and acting as stops to limit the inward movement of the blocks, and

braces extended transversely over the blocks to limit their upward movement and having their ends secured to the outer faces of the side members. y l

3. A metallic tie including a frame having block receiving end portions including side members and base plates,`brace members extending transversely of .the tie and having their side -portions secured to the side members, and extensions formed integrally with said braces and adapted to engage over the outer flanges of arail.

4. A metallic tie including block receiving ends members, side members connecting the end members, base plates, and braces-for the side 4members including flan ed extensions Y rected spaced side webs, the outer ends of which Iare provided with upwardly extended shoulders adapted to receive the' outer flange Y of a rail, and braces connecting said shoulders adapted to bear over the outer rail flange. i

6. A metallic tie including end members having a horizontal weband upwardly di' rected spaced side webs, the outer ends of which are provided with upwardly extended shoulders adapted to receive the outer flange of a rail, braces connecting said shoulders adapted to bear over the outer rail flange, and additional braces bearing over the firstbraces and having vertical flanges at their inner edges adapted to bear against the web of the rail.

y 7. A metallic tie including block holding end members having a horizontal web and upwardly directed spaced side webs, the ends of said members being open, side 'plates equal in height to the side webs of the block holding members and secured thereto to i maintain the block holding members in spaced relation, and base members equal in width to-the width of the horizontal webs of the block holding members and secured thereto, the outer ends of said base members extending beyond the outer ends of the block holding members and the inner ends of said base members extending beyond the inner ends of lthe, block holding members but terminating in spaced relation to each other.

In testimony whereof I affix my signature in presence of two witnesses.
