To all whom it may concern:

Be itknown that I, JOHN H. MILLER, a citizen of the United States, residing at Mercersburg, in the. county of Franklin and State of Pennsylvania, have invented certain new and useful Improvements in Rail Tie-Plates and Fasteners, of which the following is a specification, reference being had to the accompanying drawings.

This invention comprehends certain new and useful improvements in rail supports and fastening devices, and the invention has for its primary object a simple, durable and eflicient construction of tie plate and rail fastener, the parts of which can be easily formed and quickly placed in proper relation to the rail.

A further object of the invention is a device of this character which, in applied position or operation, will securely hold the rails from tilting and spreading, which will be so constructed and arran ed that movement or displacement of the tie plate and its component parts will be effectively prevented, which will securely hold the rails as against any laterally shifting movement and which may be easily and quickly adjusted, so as to shift either rail, when required, to restore and maintain the required age.

'A still further object of. t e invention is to provide, more specifically, an improved construction of tie plate and rail support and fastener in which the parts that directly support and engage the rail are so proportioned and arranged that the'fstronger or heavier bearing willlie on the inside of the rail so as to assist in. efliciently withstanding any tendency to tilt and spread. And the invention also aims to generally improve devices of this class-and to render them more useful and commercially desirable.

With these and other objects in view, as

will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations ofthe parts that I shall hereinafter fully describe and claim. 1 a

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing in which,

Figure 1 is a longitudinal sectional view of my improved tie plate showing it attached to a metallic tie. Fig. 2 is a top plan view thereof. Fig. 3 is an end view,

and, Fig. 4 is a detail perspective view of one ofthe plates or sections of the rail sup-.

, s eineamntr Letters Patent. PatentedJuly 23,-191 2. .Alpplication filed April 12, 1912. Serial'No. 690,325.

Referring to the drawing, the numeral 1 designates my improved tie-plate which is composed of metal and which may be formed as a single or one-piece steel casting, requiring no mill or machine work for its formation, said tie plate being formedat its ends with a ertures 2 for the receptlon of spikes or ot er fasteningdevices, whereby t e. plate may be rigidly and permanently connected to the tie.

The tie plate 1 is formed near its ends with undercut flanges 3 which extend from one side of the tie plate to the other, in the present embodiment of the invent-ion, and which are formed, preferably, with slightly sloping outer faces 4 and with threaded apertures 5 extending inwardly and slightly downwardly therethrough to the inner sides of the flanges. In the present instance, there is a pair of these apertures formed {in each flange. The threaded apertures 5 are. de-

signed to receive bolts 6 which work inwardly therein and which are preferably. provided with pointed inner ends and with square or other many sided heads 8, whereby the. bolts may be easily turned by the application of a socket wrench or similar tool thereto.

The inner ends 7 of the bolts 6 work in sockets 9 that are formed in the outer side edges of chair sections 10 and 11 which'are adapted to be-slipped by an endwise movement into engagement with the plate and underneath and between the flanges 3, each of said chair sections bein formed with an undercut flange12designe to overhang and securely engage one of the base flanges of arail, as clearly illustrated in the drawing. The chair section 11 is formed in its lower face with a recess 13 and the chair section 10 is formed with a corresponding tongue ex- Fig. 1. These two parts are preferably so arranged that spaces will be left at the ends of the joint thus formed so as to compensate for wear and permit the two sections to be adjusted inwardly, one upon the other,

as required. They are also so proportioned relative to thespace between the undercut flanges 3 that the entire chair may be shifted laterally in either direction so as to adjust the rail-for ga e. V

From as much 0 'the description as has preceded, in connection with the accompanying drawing, it will be understood that in the practical operation and use of my improved tie plate and rail fastening devices, after the plate has been secured by spikes or other fastening devices to the tie, and the rail supported between the undercut flanges 3, the sections 10 and 11 of the chair are slipped by'a transverse movement into engagement with the base flanges of the rail and the chair is then slipped by an endwise movement in between and undehneath the undercut flanges 3 until the sockets 9 register with the inner rounded ends 7 of the bolts 6, whereupon the bolts are worked inwardly and downwardly in the threaded apertures 5 into firm engagement with the chairsections which are thus forced inwardly toward each other and the rail ti htly clam edin position upon the tie p ate. In or er to shift the rail for gage, it is only necessary to loosen up on one pa r of bolts 6 and to insert a crow-bar or similar instrument between the vertically disposed shoulders 12, 3 of one of the chair sec tions and the adjoining flange 3, whereby to secure the required leverage "to move the rail over to the required point. The bolts are then again tightened up so as to securely hold the rail in the position to which it has been adjusted.

It will thus be seen that I have provided a very simple, durable and eflicient construction of tie plate and rail fastening devices, by the use of which a rail will be positively prevented from tilting and spreading, in which the bolts 6 not only securely clamp the chair sections 10 and 11 upon the rail to prevent any lateral movement or shifting thereof, but also by engagement in the sockets 9, prevent any longitudinal displacement of the chair sections, and in which the parts are so constructed and arranged that the chair sect-ions will, when the bolts are tightened up, be held firmly down upon the tie plate and also firmly hold the rail in position.

It is to be understood that my invention is not limited to the precise construction and arrangement of parts hereinbefore described and illustrated in the accompanying drawing, as various changes may be made without departing from the scope of the invention, as defined in the appended claims. It is also to be understood that my improved tie plate and rail fastening devices may be used with equal facility with wooden or metallic ties.

When used with wooden ties, it is obvious that the tie plates will serve, to a considerable degree, to increase the longevity of the tie for actual service, as it will be only necessary to spike .the tie once when the tie plate is initially placed and secured in position, ,thereby avoidin the disinte 'ation of and injury to the tie by repeats spik- I f desired, the tie plate and rail fastening devices may be used with a metallic tie that I have designed, such as that illustrated in Fig. 3, said tie being formed of a single sheet of steel bent u on itself to produce a hollow structure with downwardly and inwardly beveled sides 16 and with a bottom 17 which lies substantially parallel with the flat top of the tie, the'side edges of the sheet being brought into abutting relation with each other, but preferably not directly connected. With a tie of this formation, it is evident that proper ballast may be had, as the ballast may be fastened and packed down underneath the inwardly beveled sides 16 and thus prevent the tie from sinking, the ballast between two adjacent ties being banked at the ties by this bevel formation so as to effectually resist downward stresses. Preferably, in arranging the parts, the heavier chair section 10 with its extended tongue 1%, is disposed on the inner side of the rail, so that the device may resist, to a maximum degree, the tilting strains to which the rail is subjected, particularly on curves.

What I claim is 1, A device of the character described, comprising a tie plate formed for attachment to a tie and provided with undercut flanges facin each other, a chair consisting of sections a apted to he slipped by an endwise movement underneath said flanges, one of said chair sections being formed in its lower face with a recess and the other section being formed with a tongue extending into said recess, both of said sections being formed with flanges for engagement with the base flanges of a rail, and bolts working inwardly through the undercut flanges of the tie plate and adapted to engage the outer side edges of said chair sections, for the purpose specified.

2. A device of the character described, comprising a tie plate formed for connection to a tie and provided with undercut flanges facing each other, said flanges being formed with inwardly and downwardly opening threaded apertures, bolts working in said apertures, and a chair consisting of mating sections adapted to he slipped by an endwise movement underneath sald undercut flanges, said sections being formed with undercut flanges for engagement with the base flanges of a rail, one of said sections being formed with a recess and the other with a tongue extending into said recess underneath said recemed section, both sections being formed in their outer side edges with sockets for engagement by the inner ends of said bolts.

3. A device of the character described, including a tie plate arran ed for attachment to a tie and formed wit undercut flanges facing each other, a chair consisting of sections adapted to be slipped by an endwise movement underneath said flanges and formed with undercut flanges designed for engagement with the base anges of a rail, and fastening devices extending throu h said undercut flanges of the tie plate and a signed for engagement with the side edges of the chair sections, for the purpose specivertically dis osed shoulders spaced from each other, w ereby a tool may be applied thereto to wedge the chair in one direction or the other, as required. i

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
