RAILWAY-TI E.

SPECIFICATION forming part of Letters Patent No. 375,996, dated January 3, 1888.

Application filed September 27, 1887. Serial No. 250,837. (No model.)

To all whom it may concern.-

Be it known that I, TILLIAM P. HALL, a. citizen of the United States, residing at Piqua, in the countyof Miami and State of Ohio, have invented certain new and useful Improvements in Railway-Ties, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention'has relation to certain new and useful improvements in railway cross-ties, it having particular reference to that class or character of ties whichconsist, essentially, of

a single strip or sheet of metal bent or formed into shape while hot by means of suitable tools and appliances, as will fullyhereinafter ap pear.

The invention also relates tonovel improvements in rail-chairs to be attached to the tie to hold and clamp the rails securely thereon.

The principal objects of the invention are to produce an extremely light and durable cross-tie at a minimum cost, which will at the same time possess sufficient strength and firmness to support the great weight transported over the railway; also, to provide a tie that will possess and retain the requisite amount of elasticity to prevent injury to the rollingstock; also, to provide a tie which will present a bearing surface that will possess the necessary superficial area for the adequate support of the rails; also, to provide a tie whose sides or limbs will not spread while in use, but will retain their original shape and elasticity for a comparativelylong time; also, to provide a bearingsurface for the rails which will afford a sure and ready means of attachment for the rail chairs or fastenings; and, also, to provide for attachment to the improvedtie a rail-chair of simple and inexpensive construction that may be readily applied to the tie, and which will, when so applied, preserve the alignment of the rails and at the same time serve to assist in preventing spreading of the tie and add materially to 'its elasticity and strength, as will be more fully hereinafter specified.

That others skilled in the art may use and construct my invention, I will now proceed to describe it, reference being had to the accompanying drawings, in which Figure 1 represents a perspective view of the tie with the rail'chairs' attached thereto;

.by means of suitable appliances.

Fig. 2, a vertical transverse sectional view of the same taken through one of the rail-chairs; Fig. 3, a vertical transverse sectional view of the tie taken through the switch-rail chair; Fig. 4, a perspective View of the switch-rail chair before it is applied to the tie; and Fig. 5, a perspective view of one end of the improved tie, showing the slight notches or indentations in the edges of the T-shaped bearingsurfaces for the reception and retention of the rail-chairs.

My improved tie A is constructed of a single sheet of metal formed or rolled into shape The broad bearing-surface B is formed by making two bends orfolds, a, longitudinally through the sheet of metal at equal distances from a central line drawn through the sheet and folding or bending the two outer portions of the sheet close under the center portion, preferably until they meet midway thereof, wherethey are again bent or folded at b and turned downwardly, the contiguous faces of these folded portions being pressed into close contact. The two outer portions of the sheet are separated a short distance below the bearing surface 13, and carried downward and curved outwardly to form the convex elastic sides 0, the lower extremities of which are slightly turned in toward the vertical center line of the tie to prevent them spreading and afford the desired amount of elasticity. The sides, when thus bent, form, approximately, arcs of the same circle, and their lower longitudinal edges are bent outwardly at c and turned up, so as to form flanges ,D, which set at an acute angle to the sides 0, as shown, to assist in preventing spreading of the same.

It will be readily seen that by folding the metal upon itself, in the manner described, I have a broad and ample bearing-surface for the rails, that will be very strong in proportion to its weight, and will also afford means whereby the rail'chairs may be rigidly secured to the tie to resist spreading of the rails when in place. The sides 0, as constructed, are not only prevented from spreading, but also add strength and elasticity to the tie.

In the projecting longitudinal edges a of the bearing-surface of the tie, at the proper distance apart, I form indentations, notches, or

depressions d, for the reception and retention of the rail chairs or clamps E, these notches serving to hold the rails in perfect alignment and obviating the necessity of using belts or rivets or shoulders in the tie for that purpose.

The rail-chairs are each formed of a single strip of metal cut to a proper length, and provided about midway its length with ears 6, which are adapted to be bent over to clamp the flanges of the rail when in place upon the tie. The strip is bent to a shape similar to the tie, and is slipped over its end while hot, and it is then shrunk and forced into the notches (Z and under the projecting flanges of the bearing-surface, the ends of the strip being carried down to the side of the tie, and turned up at their ends to rest upon the flanges D. The chair thus formed will closely embrace and strengthen the tie, and all possibility of lateral movement upon the tie is obviated by means of the notches (Z, in which the chairs are forced or shrunk. The chairs are so formed and secured to the tie that the ears for clamping the rails will be on top of the rail-bearing surface of the tie, as shown. By thus forcing or bending the limbs of the chair up under the flanges of the bearing-surface I not only strengthen the same, but the chair is rigidly and permanently attached to the tie, so that it will not work loose from the continualjarring of the trains passing over the road; and by continuing the limbs of the chair downwardly, as shown, and bending them so as to closely embrace the curvcd's'ides O and rest upon the upturned flange D, I greatly strengthen the sides and render them more elastic, and also assist them in retaining their original curvature. The switch-rail or guard-rail chairs F are also formed of a single strip of sheet metal, and are adapted to be clamped upon any desired portion of the T-shaped bearing-surface of the tie. The strip is provided at a proper point in its length with ears 6 for clamping the rail-flanges, and at one of its ends is bifurcated so as to form two tongues, h, for clamping the flanges of the bearing-surface of the tie. The strip is first bent into the shape shown by Fig. 4t-that is, one end of it is bent and curved so as to closely embrace the flange of the bearing-surface and extend a short distance down upon the convex elastic side 0, as shown at 7;, and one of the ears 6 is turned up to the proper position to clamp the railflange. The chair is then applied to the tie and forced or pressed into the slight notches d in the edges thereof, as shown clearly in Fig. 3, the tongue it being bent around closely under the flange of the bearing-surface to clamp the chair securely thereto.

The object in extending the end 7c of the strip of the chair Fdown upon the side of the tie is to assist in securely and permanently attaehing it to the tie, as the tendency of a heavy weight upon the chair will be to clamp the side of the bearing-surface upon which the extension is placed, as is evident.

It will be evident from the foregoing that the essential features of my present invention are the broad, firm, and very strong bearingsurface for the rails, so constructed as to afford a ready and secure means of attachment for the rail-chairs, the elastic sides so con structed as not to spread or lose their shape, and the rail-chairs adapted to embrace the T- shaped bearing surface and the elastic sides of the tie in such a manner as to be permanently attached thereto and strengthen and render them more elastic.

I wish it understood that I do not confine myself to the exact construction of parts shown and described, for it is evident that any person skilled in the art might vary some of the parts without departing from the spirit of the invention.

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