CROSS-TIE.
laterally to compensate for the expansion and contraction thereof and ,to partlyab- 'sorb the transverse thrust of the vehicle trucks thereon, particularly at curves, switches, etc.
With this and other objects in view, such as are brought out. fully in the following specification and appended claims, the invention presents a construction illust-rated in the accompanying drawings, in which- Figure 1 is a side elevation; Fig. 2 is a top plan view; Fig. 3 is a central, vertical, longitudinal section; Fig. 4 is a bottom plan view; Fig. 5 is an end view; Fig. 6 is a section on the line 6-6 of Fig. 3, Fig. 7 is a perspective of the immediate rail support; Fig. 8 -isa plan view of a curve of track employing the device; Fig. 9 is a section on the line 9-9 of Fig. 8; and Fig. 10 a section on the line 10--10 of Fig. 3. ,y
Referring to the drawings, the tie consists primarily in a hollow casing 10, slightly 'oblong in cross section, with a bottom wall -11 considerably thicker than the others, and oppositely extended in the regions of its ends to form a reinforced supportingA surface 12. The bottom wall is furthermore vprovided with a recess 13, increasing in depth toward the transverse center, and this recess is in turn provided with a series of converging grooves 14, for a purpose hereinafter described. Extending from the recess 13 into the casing 10 are a plurality of holes 15, adapted to drain the interior of the tie, while protruding outwardly and downwardly therefrom are abrupt projections 16. The to wall of the casing is substantially at, with its side edges 21 rounded throughout a part of their length, to offer less obstruction to any chains, hose-cou plings, etc., which miglithang from cars passing thereover. The wall 20 is furthermore provided with `rectangular apertures 22, disposed centrally above thereinforced sup- Specicaton of Letters Patent.

porting surfaces 12 of the bottom wall and extending Hush with the inner side walls of the tie. Immediately adjacent to said apertures and integral with the side walls 23 of the casing' 10 are inwardly projecting shoulders 24, beginning directly beneath the top wall 2O and extending to within a short distance of the bottom 11 of the casing.
Within the tie resting upon the reinforced portions 25 of the base and extendingv approximately one-half inch through and beyond the apertures 22, are blocks 30, from one-half to one inch shorter than said apertures. The block is made of any suitable material, and this may act when made of wood, for instance, as a cushion for the rails 31 secured in any desired manner thereto. Covering and secured to the bottom of the block is a metallic plate 32, while L plates 33 are secured to and arranged to protect the vertical edges thereof. Each of the blocks 30 is drilled substantially centrally throughout its length, and extending through and between the two blocks is a rod 35. The rod 35 is provided with threads 3G for a considerable distance inward from each end, and around said threaded portions are similar heavy tension springs 37, pressing normally against washers 38, adjacent to the respective blocks and held in semi-compressed condition by nuts 39, said nuts in turn being prevented from disengagement with the rod by cotter pins 40, or the like. Furthermore, the rod 35 at intervals throughout its length between the blocks 30, extends through and in sliding engagement with a plurality of brackets 41, integral with and extending upwardly from the base of the tie casing. By this construction the tie as a whole is raised when the rails 31, secured to the blocks 30 are raised, and said blocks are thereby maintained in normal position adjacent to the bottom of the tie casing. On the outside of the casing and extending upwardly from the lateral projections of the reinforced portions 12 are webs 42, tying the said project-ions to the side walls of the cross tie and adaptedto make the latter aid in the support of the upward pressure upon the former.
The device as a whole in its preferred form when assembled is best shown in Fig. 3 in cross section, and operates as follows: The rails 31 are secured to the blocks 30, lwhich are normally pressed wit-h equal force against the innermost walls of the apertures 22 in the top wall 20 of the casing' of: ballast (not shown), which extends up` ward into the recess 13 and encircles the projections 16. As is customary, the bailast is tamped beneath the tie, and engaging the projections 16 and the end walls of the groove 13, prevents the tie'vfrom any material longitudinal `movement. There is then left practically unrestrained the horizontal vibrations of the tie, principally those in a longitudinal direction, and these vibrations by the construction of the recessed and grooved base are utilized to solidify or settle the ballast once tamped thereunder, the inverted V-shaped recess tending to :torce the particles of ballast toward the transverse center, while `the converging grooves also assist to the same end in the same direction, as well as increasing l track.
the compression toward the longitudinal center.
In the operation of the device, when in position on the road-bed and with the re spective rails secured to the blocks thereover, said rails are normally maintained at their innermost limit of movement, which may be any vpredetermined gage. When a car or train is sent over the rails at any rate of speed within a. predetermined limit, no relative change takes place in the position of either rail, but when a train at high speedl takes a curve or switch provided with this device, as with all others, the coetlicient of safety of the outer rail against spreading decreases with an increase in the speed ot' the train. `When the speed of the train has becomesuch that all of the coefficient of safety on the rail mentioned is eliminated, something must give, such as a wheel, flange or rail, either of which often breaks, or in the latter case, are thrown from their fastenings and spread, ,and -in either case permitting part or all of the train to leave the With these facts in view, the present invention has been designed to permit the necessary something l to give, and that something is the rail against which the great side thrust is exerted. But in permitting the rail to yield, in extreme cases the amount and extent of that same yielding is governed and limited, the former by the tension of the springs, and the latter by the extent ofthe aperture surrounding the rail supporting blocks. Furthermore, by the longitudinal position of the rod 35 being entirely governed by `the blocks, any displacement of either block causes one-half as much displacement of the rod, thereby permitting bot-h springs to share equally any rail displacing thrust on either block.
Leccese While the foregoing use of the device, as
stated, is designed for controlling the outcome in the caseof excessive speeds only, there is another use for which it is designed, and which makes the venlployment ot' the cross tie on straight stretches of track desirable as well as on curves, switches, etc. This use is to. control the shape and position of the rails when forced to curve by con-4 traction and expansion, due to changes inv temperature. Whereas in the` present case in which rails so affected pull out or shear 0E the spikes intended tosecure them to the ties and bow upwardly or horizontally, the device yherewith presented forces the bowing to remain in a horizontal plane and permits it to extend over a greater portion of the track without loosening the grip of the spikes thereupon., and at everyypointlimits vthe extent of the bowed displacement from one-half to one inch. TWith this restriction and the fact that a standard wheel base outsidet-he flange is at least three inches, it is clear that while one or both rails may be zigzagged for quite a distance, at no place will a wheelever get nearer to the inner edge of a rail'than from one to two inches.
It is not intended in the foregoing de scription to limit this device to the exact details of construction described and illus-- trated, but any alterations may be made therein which do not depart from the spirit oi"A the invention or the scope of the appended claims.
Having thus described my' invention, what I desire to protect by Letters Patent or' the United States is:
