Application filed November 30, 1903. Serial Nor 183,190- No model.)

To all whom, it may concern.-

Be it known that I, HAROLD V.MORDAUNT, a citizen of the United States, residing at Maiden, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in a Combined Tie bodying my invention, and said invention is fully disclosed in the following description and claims.

" Referring to the drawings, Figure 1 is a perspective view of a railway-tie and railfastening embodying my invention and show- .ing the part of a rail in vertical section. Fig.

2 is a top plan view of the construction,showing the portion of the rails in hd'rizontal section. Fig. 3 is an end view of the tie. Fig. 4 is a perspective view of the rail-locking key. Fig. 5 isa vertical longitudinal sectionalyiew taken through a portion of one end of the tie, showing the rail in position. Fig, 6 is a detail view representing a slight modification.

The object of my invention is to provide a metal tie for railway construction and afastening device cooperating therewith for supporting -the rails and holding them rigidly to the ties without the use of bolts or screws, and,further,to provide a construction of great simplicity, and consequently comparatively inexpensi've,and one which will give the greatest possible stability to the road-bed.

In the drawings, A represents the tie, which is provided with a solid flat base-plate aaof the requiredlength and width and of such thickness asto give the necessary strength. This base-plate is provided with two integral hollow blocks B, which are preferably of the same length transversely of the tie as the baseplate and of a width longitudinally of thetie' sufiicient to support the foot of a rail and leave a considerable space at either side of the' same, as shown. cored out to lighten the construction, and I prefer to formv a recess 6, triangular-shaped in vertical cross-section and with its apex adjacent tothe top face of the block, extending through the block B from one edge of the tie to the other, as shown. This form of recess gives the required amount of strength in the block at-each side of the rail-foot. The top face of each block Bis provided with two parallel vertical grooves or recesses 6', located so that their-inner edges are a distance apart equal to the width of the rail-foot, said recesses extending transversely of the tie and each of said recesses being provided with undercut portions on each side adjacent to their Each of these blocks Bis 5 bottoms, forming. shoulders b 6 The,bot-

tom of the recess is preferably tapered or V shaped, as shown at 15 although this is not The blocks B B are connected byessential. a central vertically-disposed web 0, integral with the base-plate and with :the blocks and of slightly-greater thickness than, the baseplate, and I prefer .tocut away the central portion of the vertical web C to lighten it, as shown at 'c. The vertical web is preferably produced from the blocks B B to each end'o the base' plate, as indicated at C C', the c tral portions of these extensions ofithe web being also cut away, as indicated at c 0'.

D represents 'the form of the locking-key for. securing the rails to the tie, four of which are used with each tie, as shown. This locking-key consists of a main body constructed to fit one of the recesses b and is provided adjacent to. its lower edges with shoulders d "Z projecting on opposite sides of its main body d to engage theshoulders I) b of the locking-recess. The lower part of the key is preferably V-shaped in cross-section, as

shown. at d, to fit the bottom of the recess 6. The upper part of the main body (l of the locking key is provided with a lateral pro" jection clintegral therewith and of any 'desired width to engage the foot of the rail and hold it firmly down upon the block B, the central portion 6 of which affords a broad unbroken surface the full width of the rail.

E E represent the rails, which are shown 5 ing inward and engaging the foot of the rail,

-1 have the upper face of the key secured in position. Inattaching a railto the tie A it is placed upon the central portion b of one of the blocks-B thereof, and two of the locking-keys D are driven in transversely of the tie, theirlateralprojections d extendwhile the shoulders of of the keys engage the shoulders b of the block B, and thus form a very rigid fastening for the rail. I prefer to D on each side of the locking projectiond flush with the top face of the block B; but in somecinstances I may have the main body d of the key project above the top face of the block.

I5 B, as shown in Fig.6, so that the foot of the rail lies in a channel'formed between the two keys D, thus holding the rail against lateral vibration at each side of the locking proj ection. I wish it to be understood also that, as be- 2 fore stated, the locking projection cl may be coextensive with-the length vof the key, if desired, or of any desired width less than the length of the key without departing from my invention.

On accountof the long hearing which the locking-keyshave in the recesses of the blocks there is little or no tendency'for the keys to move under the action of jar or vibration. In any case these keys could only move horizontallyor endwise, and as the entire tie is embedded in the road-bed and the earth or ballast firmly packed around the tie and above the, ends of the keys such ballast will prevent the keys from moving endwise should they have any tendency so to do.

While it is obvious that the tie and locking key could be made of any metal having the necessary strength and rigidity, I prefer provided with means for receiving rail-securing devices, anda vertically-disposed web connecting said blocks and formed integrally therewith and with the base-plate of rail-securing devices for engaging said blocks, substantially as described.

2. The combination with a tie comprising among its members ahorizontal base-plate, separated railsupporting blocks formed integrally therewith and having their upper faces provided with means forreceiving rail-secur-.

g devices, avertically-disposed Web connecting said blocks, and formed integrally therewith and with the base-plate and extensions of said Web extending from said blocks to the end oi' the tie and formed integral with said .scribe'd.

blocks and base-plate, of rail-securing devices for engagtng'said blocks, substantially as described.

i 3. The -combination with a tie comprising among its members a horizontalbase-plate, separated rail-supporting blocks formed integrally therewith and having their .upper faces 'provided with means forreceiving rail-securing devices, a vertically-disposed web connecting said blocks andj formed integrally there- -with and with the base-plate, said web being cored-out to'enable the ballast to be packed around and through said web, of rail-securing devices for engaging said blocks, substantially as described.

4. The combination with a tie comprising among its members a horizontal base-plateseparated rail-supporting blocks formed integrally therewith and having their upper facesprovided with means for receiving rail-sechring devices, said blocks being cored out transversely of the tie, a-vertically-di'sposed web formedintegrally with said base-plate and blocks and extending between said blocks, and being cored out to permit the ballast'to pack around and through said web, of rail-securing devices for engaging'said blocks, substantially as described. e I 1 5. The combination with a tie having albaseplate and separated 'rail -supporting blocks formed integrally therewith and having theirv upper faces above the plane of the base-plate, said blocks being each provided with a long recess extending'trans'versely of the tie and having undercut fpo'rtions' throughout its length, of a locking-key having a main body- ,of substantially the length of said recess, and

I constructed with lateral projections to engage theundercut portions thereof, said keys being provided with lateral rail-engaging projections, each ofsaid blocksbeing provided with means for engaging the foot of the railon the side opposite said key, substantially as -de- 6. The combination with a tie having abaseplate, and separated rail-supporting blocks 'i'ormedintegrally therewith and having their upper faces above the plane of the base-plate, said blocks having their upper faces provided with parallel vertical recesses extending transversely of the base-plate, said recesses having undercut portions below the face of said block perpendicular to the walls of said recesses, of a locking-key having a main body of substantially the same length as said recesses, and adapted to fit therein, said main body being provided with lateral pro ections forming perpendicular shoulders to engage the undercut portions of said recesses, and

being provided with a rail-engaging projection for engaging the foot of the rail, substantially as described.

i 7 The combination with a tie comprising among its members, a base-plate, separated rail-supporting blocks formed integrally therewith and having their upper faces provided with parallel recesses, having undercut portions, and a vertically-disposed web connecting said 'blocks andformed integrally therewith and with the base-plate, of a key.

having a main body provided with projections to fit the undercut portions of said recesses and having at its upper edge a rail-footengagingprojection, substantially -as described.

8. The combination with atie having a baseplate, a pair of separated rail-supporting blocks, cored transversely of the tie, and a vertical cored web connected to said base-plate and tie, said blocks having theirupper faces tie, a vertical web connecting said blocks and formed integrally therewith and with said base-plate, and extensions of said web extending from said blocks to the ends of the baseplate, of a locking-key having its main body adapted to fit said recesses and provided with lateral projections adjacent to its lower edge to engage the undercut portions of said recesses and provided at its upper edge with a lateral projection to engage the foot of the rail, substantially as described.

10. The combination with a tie having a flat horizontal'base plate, integral rail-supporting blocks thereon, cored transversely of the tie and having their upperifaces provided with undercut locking-recesses extending throughout the length of the block transversely of the tie, a vertical web connecting said blocks and formed integrally therewith and with said base-plate, and extensions of said web extending from said blocks to the ends of the base- "plate, of a locking-key having its main body adapted to fit said recesses, and provided with lateral projections adjacent to its lower edge to engage the undercut portions of said recesses, and provided at its .upper edge with a lateral projection to engage the foot of the rail, the main body portion of said key being of such extent vertically as to project above the face of the block, and forma support for the edge of the rail-foot throughout the length of said key, substantially'as described.
