RAILWAY-TIE AND FASTENEZB;

Specification of Letters Patent.

Patented Apr. 29, 1913.

Application filed January 3, 1913. Serial No. 740,059.

' In order to more fully describe my said improved tie and 20,

invention, reference will be had to the accompanying drawings wherein,

Figure 1, represents a longitudinal vertical sectional elevation of one form of my fastener, showing the clamp-in mechanism in clamping mechanism the position 1n which it clamps the rails 0n the tie;Fig. 3,

an enlarged section on line 3"-3" Fig. 2, looking in the direction of the arrow; and Fig.4, a detail perspective view of one of the locking dogs.

My invention in the form shown comprises, among otheg parts, a metal tie .consisting of, a troug1-like casting having a base portion 1,

' cross-webs 4 and 5 to stifien the structure.

, clamping dogs 15 and 16. Each the rails and plate The ends of the tie are open.

The upper edges of thesides- 2 and 3 are provided respectively with flanges 7 and 8. The rails 11 and 12 are held down on this tie by fixed shoes 13 and 14 respectively and by movable of these dogs is provided with a nose 15, the lower edge of which is adapted to engage the upper edge of the rail base; an undercut or recessed portion 15 dapted to receive the inner ed e of the rail base as well as one edge of t e plate 9 upon which the rail rests, and with a shoulder 15 under the edge of the plate 9 referred to, the said shoulder extending in the form of two wings 15 and 15 to each side of the dog, or as most clearly shown in Fig. 4. These shoulders on the dogs not only cooperate with the noses of the dogs to securely-clamp 9 together, but they act also as sup orts to the plate 9, and, therefore, as a ditional supports for the rails themselves."

The shoes 13 and 14 consist eadh of a cast the released POSltion; Fig. 2', a similar view showing the tumblers 23 and vertical sides 2 and 3, andadapted to fit up are locked in another way ing integral With-201 rigidly secured in any plate 9 of the tie, and

desired way to tlie itop and web of are adapted to engage the base the rails as shown.

The dogs 15 and 16 are hinged by means of bolts 17 and. 18 respectively, on lugs or uprights 19 and 20 cast on the base of the tie, and the heads of these dogs are adapted to swing into the locking position through openings 21 and 22, respectively, in the plate 9..

The dogs 15 and 16 are operated, re-

spectivel-y, by tumblers 23 and 24, and the latter are' operated respectively by horizontally movable arms or bars 25 and 26,

connected to said tumblers by rock shafts 27 and 28 respectively. These rock'shafts are provided each with two ofi- sets orcrank sections 29, 30 and 31, 32. The crank sections 30 and 32 carry the tumblers, while the sections. 29 and 31 are pivotally connected respectively to the ends ofthe operating arms 25 and 26. a

i Vhen the clamping mechanism is in the released position, as shown in Fig. l, the 24 rest upon the base of the tie, while the dogs 15 and 16 rest upon the upper ends of the tumblers. When it is.

desired to operate the dogs to send them into the'clamping position, the bar 25 is pulled to the left, while the bar right, Fig. 1. These operations rock the cranks 30 and 32 upward, raising the tumblers, which in turn push the clamping dogs into the positions shown in Fig. 2. In these positions of the tumblers, a fiat vertical face of each lies directly up against the back of each clamping dog, while an opposite 'face of each tumbler abuts against the top plate 9 of the .tie where the said plate forms a wall of the openings 21'and 22. The turnblers are locked in this position in two ways. This locking is efi'ected in one way by providing the bars 25 and 26 with notches 33 and 34, respectively, which are caused to engage with web 4 where the latter forms one of the walls of an opening 35, through which the said bars pass. The tumblers by wedge keys 26 is pushed to the.

36 and 37 which pass transversantly through crating the tumblers are moved to raise i any likelihood that the rails will become disthe rails from vertical displacement and act as vertical supporting braces therefor, but

placed. Not only do thedogs securely hold they are rigidly-braced by means of the tumblers from any possibility of displacement transversantly of the rails.

While I have herein described but one specific embodiment of my said invent on, it will be understood that the same is susceptible of modification without departing from the spirit of the invention. It should also be ,understoodfthat I do not limit the application of my improved clamping mechanisms to the special style of tie shown, since there are many other forms of tie with which it may be used.

What I claim is:

1. The combination with a railway crosstie, of a clamping dog hinged within the tie and adaptedto engage the base of the rail, a tumbler adapted to raise the dog into the clamping position and to form a chock against the back of the dog when the dog is in the clamping position, and means to operate said tumbler. I

22 The combination with a railway crosstie, of a clamping dog hinged below the rail and adapted to engage the base thereof, a tumbler adapted to raise the dog into the clamping position and to form -a ,chock against the back of the dog when the dog is in the clamping position, means to operate said tumbler and means to lock said tumbler in the clamping position.

3'. The combination with a railway crosstie, ,of a clamping hinged dog adapted to engage the base of the rail, a tumbler adapted to raise the dog 1nto the clamping position and to-form a chock between the back of the dog and a portion of the tieqwhen the dog is in the clamping position, a shaft having a crank portion on which said tum-J 55,

bler is mounted,an d means to rock said shaft to operate said tumbler.

4c. The combination with a hollow metal railway cross-tic, of a pair of clamping dogs hinged within the tie and adapted to engage the baseof the rails,a tumbler for each of saiddogs adapted to raise said dogs into the clamping position and to form each a chock between the back of a dog and a portion of the tie when the dog is in the clamping position, asha-ft for each of said tum blers having a crank portion on which the tumbler is mounted, means to rock said shafts-to operate said tumblers, and means to lock said tumblers in the clamping position. s w 4 s 5. The combination with a railway crosst -ie, of a clamping dog below the rail and adapted to engage the base of the same, a tumbler adapted to raisethe dog into the clamping position and to form a chock against the back of the dog when t-he dog 7 is in the clamping position, means to operatesaid tumbler, and a shoe rigidly'secured to the top of the tie and adapted to engage the railbase on the opposite side thereof from said dog and tocooperate with said dog to secure said rail to said tie.-

6. Thecombination with a railway crosstie and the track rails carried thereby, of a pair of clamping dogs hinged below the rail bases and each having a shoulder extending to each side of. the dog to form twowings or lugs and adapted to rest beneath the base to form a support therefor when the dogs are in the locked position, the base of the railbeing clamped between the head of the dog and the said shoulder.

In test-imony whereof I aftix'my signature in presence of two witnesses.
