RAILWAY-TIE.

SPECIFICATION forming part of Letters Patent No. 461,571, dated October 20, 1891.

Application filed June 6, 1891.' Serial No. 395,346. l(No model.)

To a/ZZ whom it may concern:

Be it known that I. ALVAN B. FISHER, a citizen of the United States, residing at Rutland, in the county of WVorcester and State of Massachusettshave invented a new and useful Railway-Tie, of which the following, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.

The obj ect of my presentinvention is to provide a cheap and efficient railroad-tie; and it consists in the peculiar structure and arrangement of parts as hereinafter explained, and as illustrated in the drawings, wherein- Figure 1 is a plan View of my improved railway-tie. Fig. 2 is a half side view and half longitudinal section of the same at line fr. Fig. 3 is an end View drawn to somewhat larger scale. Fig. 4 is a transverse section at line y y, and Fig. 5 is a Vertical section of the adjustable brace on a somewhat larger scale.

In my improved railway-tie the main body A consists of a trough or.channelbeam about eight inches (more or less) in width, formed of rolled iron or steel of the required length and havin ga thin horizontal web-plate a, with integral longitudinal sides or upright fianges c along the edges thereof, said flanges being about four inches (more or less) in height. These can be formed by passing through suitable rolls or by bending up the edges from a flat rolled plate.

B B indicate removable rectangularr blocks, of wood or other suitable material, upon which the track-rails R are seated. Said blocks are fitted within the hollow of the body and confined by means of flanged plates C and D, that abut against the ends of the blocks. The blocks are preferably thicker than the depth of the body, so that the top of the block will stand somewhat above the level of the earth when the body of the tie is buried. The plates C, disposed at the inner ends of the blocks B, have their upright edges flanged and are riveted or rigidly attached to the side flanges c of the body, thereby each providing a solid abutment against which the end of the respective blocks have support. The plates D at the outer end of the blocks are respectively fitted to theinteriorof the channel of the body A, so as to abut squarely against the block, and are arranged to be conveniently removed, each plate being confined and sustained by a detachable fastening, preferably by the bar or bolt F, that passes transversely through openings in the body-anges a adjacent to the back of the abutmentplate in the manner illustrated. Said bar has a head f at one end, and is secured by a pin or key j", that passes through its opposite end. By knocking o ut the key and removing the bolt or bar F the plate D is freed, so that it can be taken out for releasing the block B, and thus facilitating the renewal of the same when required. The top edges and angles of the plates C and D are formed with overhanging lips or flanges c and d, respectively, which extend over the end angles of the blocks B for confining the blocks in position and preventing the splintering of their top edges. The plate C is fitted with a slot or recess c, through which acrowbar can be inserted. between the abutmentplate and the block. At the central part of the body lugs or wing-plates H are arranged on the outside of the tie, against which a bar can be placed for shifting the tie endwise without digging it entirely out of the earth. The lugs also helpto support the tie when in the earth.

Afeature of my invention consists in'an adjustable brace for sustaining the rail against outward side pressure. (See Fig. 5.) Said brace comprises a movable bearer l, a supporting-socket I., and suitable means foreffectin g the adjustments. One end of the bearer I is formed to fit against the rail adjacent to its head, while its other end is supported within the fixed head or socket I', preferably fitted therein by a round joint that matches againsta seat-piece z', while a screw J is threaded to the end of said socket behind the seat-piece for forcing forward the parts or permitting their retraction, thereby giving the requisite adjustment, so that the brace can bear against the rail with proper degree of resistance. The sides of the socket I are best provided with engaging-lugs m, iitted to interlock with suitable ears h, formed on the outer abutment-plates D, whereby the adj ustable brace devices are sustained at fixed position in relation to the tie in the manner substantially as illustrated. The rails R are IOO VIO

fastened to the blocks B by ordinary railwayspikes fa or in any suitable manner. 'lhe end of the brace I which bears against the rail can move up or down with the springing of the rail as trains pass or to accommodate the position as'the rail wears into the seat-block B, at the same time maintaining its bracing action. This brace device may not be used in all cases or on all of the ties, but can be put on to such of the ties as will afford side support Y for the rails at any required interval. The socket or brace-head I and the abutmentplates being provided with interlocking ears, the brace can be readily put on or removed by first releasing the abutment-plate D and then engaging or disengaging the ears and lugs while the plate is some distance back from its normal position. It will be understood that the brace-socket can, if in any instance desired, be secured in position by ordinary screw-bolts in lieu of the interlocking ears and lugs.

It will be observed that with my improved structure the blocks B can be removed and replaced without disturbing the rail R or the body of the tie, such operation simply requiring the excavation of the earth or ballast in the end of the tie and the removal of the bar F and plate D. Then after the spikes have been drawn a crow-bar is inserted behind the block through the hole e andthe block forced out longitudinally from beneath the rail. A new block can then be introduced and the parts replaced as before.

Metal railway-ties of different construction, comprising wooden blocks for rail-seats, having been heretofore devised, it will be understood that Ido not herein claim such feature as broadly of my invention.

I claim as my invention herein to be secured by Letters Patentl. rlhe Within-described railway-tie, consisting of the metal body A, having upright side iianges a', the trausversely-disposed abutment-plates C and D, having overhanging flanges c and d, respectively', at their tops and upright ianged edges fitting between the upright sides of sai body,the former rigidly fixed in position by rivets through the side flanges and the latter removably secured by transversely-disposed bars F, inserted th rough Openings in the side tianges at the back of plates D, and the rectangular wood blocks fitted between said abutment-plates within the channel of the body and confined by the overhanging top flanges c and d, said parts being constructed and combined all substantially as shown and described.

2. In a railway-tie, the combination, with the body A and the rail-seat block B, of the transverse abutment-plate C, having its overhanging flange c provided with the recess e, substantially as and for the purpose set. forth.

The adjustable brace composed ot the movable bearer and the supportingsocket provided with engaging-lugs, in combination with the body of the tie, and the abutmentplate D, having ears that interlock with said engaginglugs for sustaining said bracesocket, and means, substantially as described, for securing said plate to the body of the tie, for the purposes set forth.

4. In combination with the track-rail and railway-tie, the adjustable rail-brace com posed of a head or socket sustained at fixed position upon a stationary part. of the tie, the movable bearer seated in said socket and capable of limited upward and downward swinging action, and the adjusting-screw fitted in said socket and adapted for pressing forward said bearer, substantially as set forth.

Vitness my hand this 1st day of J une, A. D. 1891.

ALV AN B. FISHER.
