COMBINED RAILWAY TIE AND CHAI R.

SPECIFICATIONforming part of Letters Patent N 0. 647,317, dated April 10, 1900.

Application filed June 24. 1899. Serial No. 721,775. .(No model.)

To all whom it may concern;

Be it known that I, TIMOTHY W. MURPHY, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Impr0vements in a Combined RailwayTie and Chair; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. a

My invention is in the nature of a combined railway tie and chair whereby the rails are firmly locked to the tie and held against spreading.

It has been the experience of railroad men and the public that a very large proportion of the loss of life and property by railroads is due to accidents caused by the spreading of the rails. This spreadingis caused by lack of sufficiently strong and secure supports and ties and lack of proper durable means for connecting the ties and rails. In the ordinary way in which wooden ties, ordinary chairs, and fish-plates and spikes are'used numerous kinds of defects are liable to develop by the old method, any of which would permit of the spreading of the rails under heavy lateral strains. The wood of the ties is liable to rot out withoutshowing the defect, no matfor how careful and faithful the track walker or inspector may be, and this will loosen the spikes, leaving but very little support against lateral strain. The continuous contracting and expanding of thewood' due to dry and wet and of themetal due to heat and cold also contribute to the loosening of the spikesf The absence or inefliciency of nut and bolt fastenings are also responsible for many accidents.

The object of this invention is to provide means whereby the possibility of all such accidents is avoided and whereby the rail, either intermediate of or at the joints, will be firmly clamped and held on strong and durable chairs without fish-plates, bolts, or nuts and the chairs themselves firmly held to strong metallic ties in such a manner that nothing short of the destruction of the metal will permit of the displacement or spreading of the rails.

With this object in view my invention consists in the improved construction, arrange ment, and combination of the parts of a combined railway tie, chair, and joint, as hereinafter fully described, and afterward specifically pointed out in the appended claims.

In the accompanying drawings, Figure lris a perspective view of the invention complete, the rails being shown in section. Fig. 2 is a top plan view, the rails being broken away. Fig. 3 is a view in side elevation, the rails being shown in section. Fig. 4 is a bottom plan View, the rails being broken away. i Fig. 5 is a longitudinal sectional view on the broken lines 5 5 of Figs. 2 and 4. Fig. 6 is a top plan view of the bases and connecting-bar or crosstie, all the upper parts being removed. Fig. 7 is a bottom plan of one of the chairs. Fig. 8 is a longitudinal section on the broken line 8 8 of Fig. 7. Fig. 9 is a perspective view of the movable rail clamping jaw detached. Fig. 10 is a similar view of the key-block for locking the movable jaw laterally. Fig. 11 is a perspective view of the dovetail key for locking the movable jaw and locking keyblock against vertical displacement. Fig. 12

is a perspective view of the bars for prying out the key-block. Fig. 13 is a perspective view of a modification illustrating a cross-tie and base-plates made separable. Fig. 14 is a top plan view of one of the separable baseplates. Fig. 15 is a detail sectional view on the broken line 15 15 of Fig. 14. Fig. 16 is a detail perspective view of one end of the separable cross-ties. Fig. 17 is a detail sectional view on the broken line 17 17 of Fig. 16. Fig. 18 is a top plan view of a section of road constructed in accordance with my invention.

Like numerals of reference indicate the same parts wherever they appear in the several figures of the drawings.

Referring to the drawings by numerals, 1 and 2 indicate the base-plates, which may be cast or otherwise formed integral with the connecting-bar or cross-tie 3, the latter being formed with a depending central foot 4 to prevent bending at that point. The base-plates are rectangularin form, the ends of the crosstie reaching somewhat beyond their longitudinal center and lying in their transverse center, each tie being formed with an enlarged head,,as at and 6, at its ends, said heads each having a transverse groove in its upper at 9 and 10, reaching to the plane of the foot i 4, the flanges 9 being at the inner ends and the flanges 10 at the outer ends of their respective plates. The base-plates are further provided with vertical elongated slots or openings 11, 12, and 13 and upwardly-projecting ribs or flanges 14, '15, and 16, the slots 11 and 12 being near the inner corners and parallel with the cross-tie and the slots 13 near the outer ends of the plates, their inner walls being inline with the outer faces of the heads 1 5 and 6. The ribs or flanges 14 and .15 are the ribs orflanges 16 in the same-positionsalongside of but a short distance from and parallel with the side faces of the heads and l relative .to the outer faces of the heads, the

middle portions of ribs 16 being cutaway, as at 17. The tie-heads 5and 6 and the baseplates 1 and 2, as well as the chairs 18 and 19, about to be described, are duplicates in construction; but the head 6, chair 19, and base- 1 plate 2 are larger and stronger than their opin the form to support a rail on the leftandparts arranged in the same manner and also .posites, the latter being intended to clamp and support a rail intermediate of its ends,

. while the former are intended to clamp and support theabutting ends of two adjacent rails. In Figs. 1 to 6 the parts are illustrated a joint on the right, while in Fig. 18 Ishow the arranged to support a rail at each end inter- '1 heads, andchairs being used at both ends of.

mediate its joints, the smaller base-plates, tiethe ties in the last-named arrangement.

-18 indicates the lighter chair for use on the bed-plate 1, and 19 the heavier chair for use on base-plate 2. As before stated, they are of. the same construction, each being provided with downward-depending side flanges 2O 21 and ,end flanges 22 and 23, the side flanges being provided with thickened dowj n-. .ward-depending lugs 24 and 25, adapted to enter slots 11 and 12 of the base-plates and be securedtherein by pins 26 and 27., having split ends, which will be expanded when driven in against wedge-shaped lugs 28 and 29 on the underside of the base-plate. End flange 22 has a similar lug 30, which passes down through slot 13 and is secured by a similar split-ended pin 31, which when driven will base-plate the side and end flanges are seated in the spaces between the tie-head and the . ribs 14, 15, and 16.

be expanded by a similar wedge-shaped lug 32 on the under face of the base-plate. The end flange 23'is notched at 33 to straddle the tie, and when the chair is inplace onthe Under the top plate of eachchair is a transverse rib 34 to fit in the transverse groove of the tie-head.

Each chair is formed with a solid clampingjaw 3,5v tooverhang the outer halfof the base flange 36 of rail 37. The chair is provided with a central longitudinal slot 38 and lugs 39 40 in pairs on each side thereof, said lugs beingundercuton theiradjacentfaces. Movable cl-amp-jaw 41 is provided with a key 42, depending from its under face to fit in slot 38 in thechair, provided with an outer flange.

43 to slip under the top of the chair and a similar inner flange 44. A key-block 45 slips into that part of slot 38 not occupied by key 42 and secures the movable jaw against inward movementin the slot, a flange 46 overlapping flange 44 of the movable jaw. The key-block 45 has an overhanging head 47, which may be withdrawn by means of. small crowbars 48, as shownin Fig. 1.2, the point of one-of them being placed under each side of the head and both operated simultaneously. Thetop of the flange 46 and of the inner edge of the movable jaw are flush with thetop of the chair and meet between the two pairs of undercut lugs 39 and 40. Adovetail key 49, driven between the undercut sides of the lugs 39 and 40, overlaps these parts and prevents them from being vertically misplaced, the key being split at the end to permit of its being spread, when desired. lVhere asolid rail is clamped, I have marked it 37, and where two rails abut each other in the chair I have marked them 37iand 37*.

As before stated, the-base-plates .1 and 2 may be made integral with the tie; but they may also bemade separate therefrom, as illustrated in Figs. 13t0 17. In these figures I show the tie without the enlarged heads, although this is not necessarily so. The head may be used or not, as may be desired, and

, under each end of the tie is formed a wedgeshaped dovetail. lug 50, which is adapted to engage in a recess between the undercut ribs or lugs 51 on the upper face of the base-plates, the smaller ends ofthe lug 50 and of the recess being inward. The dovetail arrangement holds the tie tight upon the base-plate, and the wedge shape prevents the further separation of the base-plates after the lugs have beendrawn into the recesses At the inner edges of the base-plates are knobs or projections 12 for supporting the tie level with the .topof the undercut ribs 51 of the base-plate.

By means of this arrangement a tie or-a base plate maybe renewed when broken .or: faulty without the necessity of renewing the solid tie and base-plates, thus economizin g to that extent.

. Combined metal ties and chairs constructed as hereinbefore described may be used, as before stated, either at the joints of rails or between the railsat other places than the joints, and their application is fully illustrated in Fig. 18, in which the invention is shown applied in both situations. In repairing or refitting a rail already built with wooden ties my improved tie and chair can be first placed at the joints and in a number of places between, leaving the remaining Wooden ties until they are worn out, when they can be replaced with those of myinvention until the whole road is thus equipped, there being so little wear that the first placed in position will be as solid and perfect as the last. It will of course be understood that with a new road as many may be used as is desired, the whole road being built' with my invention,if so elected. Rails may be slipped in position laterally from the inside, instead of, as heretofore, from end to end or endwise.

Of course the first cost of equipping a railroad with my new tie and chair would far exceed the old method, as the new steel rail did the old iron rail; but when a road is once equipped it will last, it may be said, forever, and I may add that the avoidance of accidents, wreckage of engines, cars, and suits for damages would soon pay for the laying of the entire railroad-bed with my improved tie, besides the assurance of safety to passengers. The improved tie and chair may be adapted to the underground trolley and form the tie and chair for the yoke with good results.

While I have illustrated and described the minute details of construction of the various parts composing my invention, I desire it to be understood that I do not restrict myself thereto, but hold that any slight changes or variations, such as might be made by the ordinary mechanic after inspecting my specification, would be clearly included within the limit and scope of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The combined tie and base-plates, the base-plates being provided with supportingflanges and with undercut ribs on the upper faces, converging inwardly, and the tie with dovetail wedge-shaped lugs on its under faces to engage between the undercut ribs, said base-plates having openings to receive lugs on the chairs, and the ties having transverse grooves to receive ribs of the chairs, whereby the chair may be secured to the base and tie substantially as described.
