RAILWAY-TIE'.

STPEUFICATION forming part of Letters Patent No. 535,155, dated March 5, 1895.

Application filed April 21,1894. Serial No. 508.417. (No model.)

To all whom t may concern:

Be it known that we, STEPHEN W. BALDWIN, of New York, in the county of New York, and -WILLIAM A. SWEET, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Railway-Ties, of which 'the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.v

Our invention relates to metallic railway ties, and means, appliances and mechanisms for connecting or securing the rails thereto and securing it in the road bed.

The object of our invention is to produce a metallic railway tie, in which the body is composed of sections secured together by transverse plates; in which each section is constructed of two or more bars of T-shaped iron or steel, or of other rolled shape; in which the transverse connecting plates constitute chairs upon which the rails lie; in which abutments, or an abutment plate is connected tothe tie, and grip plates bear at one end upon said abutments and at the other upon the rail anges to secure each rail upon its chair plate; in which each tie is provided with a vertical transverse anchor, or anchors, which prevents the tie from shifting longitudinally; and in which the longitudinal sections are separated from each other, thereby creating a tamping-slot between them.

Our invention consists in the several novel features of construction and operation hereinafter described and which are specifically set forth in the claims hereunto annexed. It is constructed as follows, reference being had to the accompanying drawings, in which- Figure l, is a top plan of a tie and parts of two rails. Fig. 2, is a front elevation thereof. Fig. 3, is an end elevation of a tie, and part of a rail thereon in side elevation. Fig. 4, is a top plan of the tie. Fig. 5, is a vertical sectional elevation of part of the tie, rail thereon and means ford/connecting the tie sections, and securing the rail thereon. Fig. 6 is a side elevation and a top plan of the abutment plate, detachedmFig. 7, shows two perspectives of grip bars, showing slight differences in construction. Fig. S, is a front elevation of one style of anchor, detached, before it is bent. Fig. 9, is a like view of another anchor, slotted to receive the webs of the tie sections. Fig. 10, is a side elevation of the anchor showing the arms bent laterally with a single angle or curve. Fig. ll,isalike view showing the arms bent over with two angles, or curves. Fig. l2, is a top plan of part of a tie, showing partly in full and partly in dotted lines an anchor of the style shown in Fig. 9, secured to the tie sections. Fig. 13, is a side elevation of an abutment like that shown in Fig. 6, and having one of the grip-plates integral with the body. Fig. 14, is a side elevation of an anchor and a brace connected thereto.

-A- is the tie', comprising a body consisting of two or more longitudinal sections -a, of any suitable metal, each being of T-shape, or of other rolled shape, in cross section and inverted so that the longitudinal web is on the under side, or buried in the cart-h, while the space -bbetween them is the tamping space. Chair plates -care secured to and connect said sections, andthe heads, or the outer projection of the bolts or rivets -cform a channel iu which the flange wdof the rail cZ lies, said heads bearing laterally against it.

A plate -chaving its ends upturned to create the abutments -cis inserted under each of said chairs and between said sections, and lthare grip plates, at one end engaging with said abutments, and at the other bearing upon the flange of the rail, -hbeing a bolt inserted through each of the grip plates, chairs and plate -e--on each side of the rail, by which said parts are adjustably secured together and the rail is secured upon the tie.

To prevent the longitudinal shifting or movement of the tie, where necessary, as upon curves, an anchor -cis provided, comprising a plate having arms -twhich are bent over in opposite directions by a single angle or curve, as shown in Fig. 10or by two angles or curves as in Fig. ll, the latter being the stronger method, and less liable to frac ture under strain.

In Fig. 9, the anchor is shown as provided with vertical slots mcreating two arms at each end of the anchor, the arms of each pair being bent in opposite directions, and

ICO

the webs ot said sections fitting into said slots, whereby the area of the anchor is largely increased, as well as its strength, against lateral strains, to prevent the longitudinal shifting of the tie. These anchors are secured by bolts or rivets through the ange of each section, and stand vertically transverse thereto.

The sections can be produced by cutting the heads off from old railroad rails, and rolling the web and ange down to the desired thickness, and cutting to length.

In the drawings the tie sections are shown as T-shaped in cross section, but we do not. limit ourselves to that form, inasmuch as the principle of our invention will enable us to use many different types or styles of rolled shapes for such sections in constructing ties in sections which are spaced apart and connected or secured together by chairs, connections or anchors in separate pieces, or combined to create either a combined chair or anchor or a combined connection and anchor.

Vhat We claim as our invention, and desire to secure by Letters Patent, is-

1. A railroad tie comprising two or more parallel rolled-shape sections, flat chairs secured thereon, grip-plates inserted under said chairs and provided with end abutments projecting above them, clips engaging with said abutments and with the flanges of the rails lying upon said chairs and bolts through them andthe chairs and grip-plates in combination with a rail.

2. A railroad tie comprising two or more parallel rolled-shape sections, chair plates secured thereon transversely, grip-plates secured to said chairs and having upt-urned ends projecting above said chairs, clips engaging with the rail flanges and provided with tongues engaging with the grip-plates and means to adj ustably secure them, in combination with a rail lying lupon said chairs.

3. The combination with a rail of a tie consisting of T-shaped sections, rail chairs connecting them, an anchor fitting over the ribs of the sections and having oppositely bent arms secured to the sections on the opposite sides of said ribs and extending below them, abutment plates secured to said chairs, gripplates engaging with the abutments and with the rail flanges, and bridging over the spaces between said abutments and said flanges and means to secure said grip-plates tothe chairs and abutment plates.

4. The combination with a rail, of a sectional tie having a tamping slot between the sections, a chair connecting the sections and engaging with the rail, an abutment plate, grip plates engaging with the abutments and with the rail anges and bridging over the spaces between them, and means to secure said plates in position.

In witness whereof we have hereunto set our hands this 9th day of January, 1894.

STEPHEN W. BALDWIN. WM. A. SWEET. In presence of- JoHN L. WILKIE, HOWARD P. DENIsoN, M. M. Bonsr.
