HARMON V. SLU'1Z,v 0F CHICAGO, ILLINOIS.

Be it known that I, Hannon V. Surry., a citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new' and useful Improvement in Railway-Ties, of which the following is a specification.

This invention relates to cross ties for v railways, and the prii'icipal'object of the invention is to provide an improved, siinple,' strong and resilient device. ot the class described which is effective and efficient in op eration.

A fiirtherobject oif the invention is to provide a tie which prevents the wheels of a vehicle passing over the rails secured there- 'fto,l from becoming rail-bound.

. j 'A still further object is to provide a tie of 'this kind which has a strong hold on the road ballast, thereby preventing the track from slipping and permitting the use of less expensive ballast.

Another object is to provide improved means for tainping the ballast about the tie and to permit the resilient action of the tie in the center.

For the attainment of these ends and the accomplishment ot' other new and useful ob- -eetS, as will appear, the invention consists in the features of novelty in the construction, combination and arrangement oi' thc several parts generally shown in the drawing and described inthe specificationi but more particularly pointed out in the appended claims. y

'In the drawing, Figure, l is a side elevation of a tie constructed in accordance with the rinci les of this invention' Fifr. 2 is a .plan View of the saine; Fig. 3 is a longitudinal sect-ion of the saine showing,l the ballast disposed about the tie; Fig. 4t is a cross sectional view 'on the line 4-4 oit' Fig. t.

` One of the difficulties to be overcome in railway construction is to provide means for preventing the rails from beinginelined outwardly When a-load is imposed upon ,the

`rails. This iscaused in case of the ordinary 'action of the car trucks in passing over any tie, will cause, in time, an up and down movement of the end of the tie, since itis Specification of Letters Patent.

evident that. the center of the tieLis lsupported by the ballast underneath it, and the weight imposed upon the tie is directed to- 'ai'd the` ends thereof.' ".lhis causes a bulging action in the centerv o'f tht` tie which finally results in the ends of the tic being permanently depressed, whereby the i'ails will be. tilted outwardly from their original position and the inner edges of the balls ot the rails, will be moved upwardly and will engage the flanges of the wheels as they pass over the rails. This causes the wheels to become bound between the rails and results in an undue wearing of the rails. larticulai-ly is this true in"constructions where the pal object to obviate this dilliculty as well as to provide an improvedlight. and simple resilient construction which has a superior hold upon the road bed7 and which may be regulated as tai' as the resilient action ofthe tie itself, is concerned.

teferring now more particularly to the drawing', a resilient member l() preferalily i of channel shape in cross section` as shown clearly in Fig'. fl, is composed of any suitable inetallie material, such as 'steel l or wrought iron aml the like` and is forined with substantially vertical dependin;l sid/e portionsl 11 lwhich are. preferably thinner in construction than the connecting web portion 1Q. This member l() is preferably of a length substantially the saine or slightly less than the standard tie, and is preferably formed at its center with a rounded and raised portion 1P neeessitatingl cci-responding curved reeesses 14 at the lower edge of depending side portions ll.V This rounded poi-tion `l?) is preferably provided with a tan'iping"opening 15 substantially rectangular in forni and disposed within the longitudinal axisv ofthe opening extending lengthwise of the tie menilier l0. A lid or closure lt is provided yfor this` openingF 15 and fastening devices '17, preferably bolts or'the like, are positioned at the corners to fasten the 'lid in place over theopenine'. ln

i the connecting;r web portioni12` and adjacent ipo Fig. 2, to receive fastening devices for se curing the rails 19 to tlie tie. ln the present exempliication of the invent-ion, spikes 20 are employed as the fastening members or devices as will bel presently set forth.

Disposedjat the ends of tie member 10, are blocks 21 which may-be of anydesired or suitable material, and inthe present exemplilication of the invention,.are intended to ras 'are other ties. noted in this connection that4 either one orbecomposed of wood. These blocks are positioned vbetween the. side members -of the tie, preferably extend to .the end of the tie member, and are ofsuch a length that a greater portion 'of'each block is disposed rWithout the center line of the rail than be* ltween therails. The raily is fastened to the block 21l by means of the Spikes 20 which pass through the openings 18 provided for themat the proper places adj'acent'the ends ot the tie members. It has been found with this construction that a much cheaper grade of material can be used for the blocks 2l .tor the reason that they are entirely 'covered exceptat the outerv end by thetie' member 10 and for this reason are notso'muchl subject to the action of the Weather or moist-ure .It will furthermore be are inclined weight passing over the rails,

each rall 1s inwardly for the reason that positioned nearer the inside endl of block than the outside, and if there is any tendency of 'the block to be inclined, it will be toward the center, thereby eliminating tbn possibility of tbc rail tilting' outwardly, and preventing it ,from bending thef'langcs of the wheels passing over the rails. ln

- other words, the tilting action ol the blocks prevents wheels passing;` over the rails from becoming rail-bound.

ln order to strengthen and to properly distribute the stresses and strains in thev tie member, it is provided with braces 22 and 23 which are secured on the outside ofthe depending side portions 11 of the said member 10. These braces are preferably of the same or a similar material to that of which the member 10 is composed, and they are disposed at an angle to a vertical center line and at different distances from the rails 19.

ln the present. cxeinplilication.of the inven-` tion. the braces 22% are disposed adiacent the ends et ihr lie member, andthe braces the `22 are disposed between the center lines of edge of the side portions 11 and extending between the lower ends of the braces 22 and 23, are braces 24.v These braces 24 are adapted to strengthen the support of the braces 22 and 23 and to form a lower ed of increased width for the depending si e portions.

To secure the blocks 21 in position at the ends of. the member 10 and to properly diw rect the weight imposed upon the blocks to the tie member 10, bolts or bars`25 are provided which. extend through' the blocks 21, the depending side portions v11 and the braces 22 and 23. These bolts 25 are secured in position by nuts 26 or other fastening devices at the ends thereof, and it is evident that the weight imposed upon the blocks, will be communicated by means of the bolts to the tie member' 10, so that nc severe strains are placed upon the blocks 21.

It will also be noticed that these bolts 25 are spaced with respect lto the center line of the rail so that as shown in the resent exemplifcation of the invention,L the olt at the outer end of the block is farther front the line of the rail than the bolt ofthe inner -end of theblock.

ln order to strengthen the central l' ortion of ythe tie, braces 27 are provided which are secured o-n the outside of the depending side portions and extend from the uppermiddle portion of each side at an angle, to the lower edge ofthe side at a point intermediate of the center line of the tie and the outer .end thereof. The lower end of each of these braces preferably extends to a point-adjacentthe inner end of the block 21 which is secured in the end of the tie. The object ot these braces 27 is to strengthen the tie mem-- ber at its central portion and to direct the weight imposed upon the tie by the rails toward the center of the'tie, thereby resulting in a resilient action of the middle por tion of the tie member. p

The resilient action of the middle portion of the tie member is aided .by reason of the' disposition of the blocks at the ends of the tie member leaving the' portion between the innerends of the blocks4 unsupported, and providing a space for the reception of ballast.' In ractice,- this space between the inner en s ofthe blocks 21 is filled with ballast, and a space is usually left at the top of the ballast (.seeFig. 3) boe.

tween therballast Aand the upper web of the tie member 10 so' that the upper side of the tie4 member is free tobend downv wardly upder a sullicient strain caused by si' weight imposed upon the rails. rlhe ballast within `this space is tamped in position through the tamping opening'lo, any den ist,

sired or suitable tainping tool being insei'ted through the opening for this purpose. As this chamber is closed, it is evident that the ballast contained in the chambei is not subject to the weather and nnder ordinary co1iditions even in rainy weather, is in dry condition. liy leavino' a space between the top otl the ballast in this chamber and the web connecting portion of the tie member, the resilient action of the middle portion ot' the tie member is permitted in a greater degree than would be permitted if the ballast entirely fills the chamber. As has been pre` viously described, a weight imposed upon to the track.

the tie member and upon the rails is directed toward the middle of the tie, and results in a bending action upon the middle portion which tends to bend the tie concavely. In other words, the lower edges of the depending side portions 1l of the tie member are subjected to the greatest tensional strain. The bending ot' the tie member is' by means ot' the braces which are disposed along the sides of the tie member, and which are positioned to distribute and direct the weight and tension toward the lcenter ot the tie member. With this construction, it is evident thatv a very firm hold upon the ballastis possible, for the reason that the two end blocks are embedded in the ballast and bear against it upon all sides, thus providing a double bearing surface to prevent lateral movement with respect to the track, and an additional bearing surface is afforded by the channel shaped middle structure ot' the tie member whereby both of the depending side portions engage the ballast to prevent a longitudinal movement of the tie with respect The downward bearing surface of the tie is of course the same as any other tie .of equal width. Vith this construction, it is possible and is found expedient to reduce the length of the tie slightly from that of the standard length which is considered eight feet, so that this tie is found very efficient in curves of short radius. v

A further advantage of this construction on curves of short radins is that the superior holding powerof the tie upon the ballast keeps the tie, and consequently the track, nioi'e firmly in position upon the curves, for it is upon the curves that the greatest danger of slipping of the ties, is present.

While I have thus described thepreferred embodiment of my invention,v it'is evident. that others skilled in the arts to which this appertains, may make various changes in the construction',combination and arrangement of the several parts Without departing from the spirit and scope of the invention.

What I claim is:

1.
