UNITED STATE RAILROAD TIE.

Application filed December 30, 1924. Serial No. 758,846.

To all whom it may concern:

Be it known that I, ammi Jorrmsnn, a citizen of the United States and a resident of the city of Vancouver, in the Provinc of British Columbia Canada, have invented certain new and useful Improvements in Railroad Ties oi which th following is a specification.

My invention relates to improvements in railroad ties, and the object of my invention is to devise a tie of great strength capable of being easily manufactured and of being easily laid with great facility and expedition and which is of great durability that ties of this character when laid last over a long term of years and thus the frequent renewals which are necessary with ordinary wooden ties are done away with, enabling great economy in railroad track maintenance to be effected.

I attain this object by the construction illustrated in the accompanying drawings in Which Fig. 1 is a perspective view showing one tie and a portion of another in place on a track.

Fig. 2 is a longitudinal sectional view taken through the tie,

Figs. 3 and 4 are detail views in perspective of the opposite rail joint connection members.

Fig. 5 is a fragmentary plan view, in part section, showing th rail joint connection members assembled.

Fig. 6 is a fragmentary plan view showing the movable clamp guide slots.

Similar figures of reference indicate similar parts throughout the several views.

The tie proper consists of a hollow body formed of a plate, indicated generally by the numeral 1, with flat bottom 2 and upwardly and outwardly inclined sides and a flat cover or top plate 3 riveted to the inrlined sides. At suitable points on the top plate 3 spaced in conformity with the gauge of the rail clamps 5 and 6 are rigidly secured by any suitable means such as riveting, clamp 5 being on the inside or one rail and clamp 6 on the outside of the other rail, and the inner ends of the respective clamps are offset upwardly as at 7 and 8 respectively so as to provide a space between the clamp and the top plate 3 to permit the bottom flanges 9 of the rails 9 to be placed between the plate and the clamp, as shown more particularly in Fig. 2.

On the sides of the rails opposite to the fixed clamps 5 and 6 are placed movable clamps 10 and 11 having their inner ends 12 and 13 ofi'set upwardly and formed similarly to the inner ends of the clamps 5 and 6 so that they may engage over the bottom flanges ot' the rails when moved thereagainst and to the underside of each clamp 10 and 11 are rigidly secured downwardly extending blocks 14 and 15 adapted for longitudinal slidable movement in slots 16 and 17 formed in the top plat 3, each of which blocks is provided with a threaded bore, 18 and 19 respectively, extending through it from side to side, as indicated by the dotted lines in Fig. 2. The clamps 10 and 11 are also provided on the underside with downwardly extending pins 2021 and 22-23 respectively slidably engaged in slots 24-25 and 2627 respectively formed in the top plate, which may be headed on their lower ends,- if preferred, and serve to guide and brace the clamps against lateral play during their longitudinal movements when being adjusted.

28 and 29 indicate threaded rods passed through the correspondingly threaded bores 18 and 19 of the blocks let and 15, which rods are supported in suitable cap bearings 30 81 and 3233 respectively mounted on the underside of the plate 3 and project at their outer ends through apertures 3a and 35 in the closed ends 36 and 37 of the tie, these outer endsbeing squared, as at 38 and 39, so that a suitable handle or wrench may be placed thereon for the operation of the rods. Lock nuts 10- 11 and -l2- 13 are mounted on the respective rods 28 and 29 on opposite sides of the end closures 36 and 37, shown in Fig. 2, and collars 2828 and 2929 are secured to the respective rods 28 and 29 on each side of the cap hearings to hold the rods against loi'lgitudinal movement during operation.

The clamps 56 and 10-11 described in the foregoing are for use at points intermediate the rail joints. To provide for connecting the rails at the joints the clamps are modified by the integral formation therewith or rigid attachment thereto at their inner ends of plate members 44 and 45 respectively adapted to bear on the web of the rail, plate 1a being made a part of the movable clamp indicated in Figs. 1 and 3 by the numeral 16 and t5 being made a part of the fixed clamp, indicated by the numeral 47 and shown in Figs. 1 and 4.

The tie on which the ends of abutting rails rest is made somewhat broader than the intermediate ties and the clamps 46 and 47 are mounted thereon and operated in exactly the same manner as clamps .5.6 and 10-11, On the face of the plate 44 are two projecting pins 48 and 49 spaced to engage and pass through the holes 50 and 51 farthest from the rail jointpwhich holes are generally found in the rails adjacent'their ends,*and also to pass through correspondingly spaced holes 52 and 53 in the oppositeme'mber 45, while on the face of member 45 are two projecting pins 54 and 55 spaced to engage and pass'throughthe'rail holes 56 and 57 found adjacent the abutting rail ends and alsoto pass throughcorrespondingly spaced hole-s 58 and 59 formed in the member 44, so that whenthe rails are in place and the clamps 46 and 47 tightened up the plate members 44 and 45 will grip the opposite sides of the rail web 61 while straddling the rail joint, indicated by the numeral 60 in Fig. 1, with the pins4849 and 5455 passing through the rail holes from opposite sides respectively and engaging the respective holes 52-53 and 5859, as shownmore particularly in Fig. 5; The manner in which the tie is used will be readily apparent, onreference being had to the drawings, as it will beseen that if the movable clamps 10-11 and 46 be moved away from the fixed clamps 5-6 and '47 by the operation of. the threaded rods 28 and 29 in thepr'operdirection the rails may be laid on the ties when these are spaced at the proper distance' apart and placed with their flanges on one side engaging under the offset inner ends of the fixed clamps and then secured most'rigidly by screwing in the movableclamps until their offset inner ends engage tightly on and over the rail flanges nearest them, after which the lock nuts have devised a railtie which is stron 49 41 and 42---43 are tightened up ,to prevent'any slackening of the clamps through inadvertent unscrewing of the rods 28 and 29-.

From the foregoing it will be seen that I and efiicient, capable of being laid expeditiously and with the utmost facility, and which is characterized by great durability and lasting qualities. i What I claim as my invention is l 1. A railroad tie comprising, a base, a fixed clamp for each rail carried bythe base, I a movable clamp for each rail also carried by tliebase between which and the fixed one the rail is disposed provided with an underside block having a threaded bore disposed slidably inja longitudinal baseslot, a correspondingly threaded rod for each block extending through the threaded bore thereof, "capbearings in which the respective rods are rotatably mounted, and collars secured tosaid rods on each side of the respective cap bearings. V

A railroad tie comprising, a base,a

fixed clamp for abutting rail ends carried by said base, a 'novable clamp co-acting with the fixed clamp also carried by the base, each clamp being provided on its inner end with a plate member adapted to straddle the abutting rail end jointand bearon the webs of the abutting rails on opposite sides thereof, said plate members having pins on their inner faces adapted to extend through the said webs and into and through i the plate members respectively from opposite sides when these are positioned, and means for moving andtig'htening the movable clamp'against the rail whereby the latter is gripped between the clamps. i

Dated at Vancouver, B. (3., this 12th day of December, 1924.
