Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed July 8,1905. Serial No. 268,766.

To all whom, it may concern:

Be it known that I, HARRY E. Thomas, a citizen of the United States, residing at Homestead, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Railway-Ties, of which the following is a specification.

My invention relates to certain improvements in metallic railway-ties, and has for its object the production of a simple, strong, and efficient construction which shall possess certain advantages over prior devices of similar character and one in which the various parts may be economically produced from rolled metal blanks or bars.

After a detail description of a tie embodying my invention the features deemed novel will be specified in the claims hereunto annexed.

Referring to the drawings furnished and forming a part of this specification, Figure 1 is a side view of one end of a railway-tie embodying my invention. Figs. 2 and 3 illustrate the same in plan and end views, respectively. Fig. i is a sectional view taken on line 4 4 of Fig. 1. the cross-tie in top and side views, res cctively, the rails and rail-clamping mem ers being removed therefrom. Figs. 7 and 8 illustrate the inner ra1lclampmg member in rear and side views, and Figs. 9 and 10 illustrate the outer rail-clamping member in rear and side views.

The cross-tie A employed by me may be varied as to form and structure without departure from the main features of my inven tion. It may be constructed of steel or iron, either rolled, pressed, or cast. In its preferred form it comprises a top plate (1, having a flat upper surface, a bottom plate a, and a central vertical connecting-web a It is preferably made by rolling an I-beam of proper dimensions and then cutting the beam into proper lengths to form the ties. The top plate (1 forms the support for the rails B, which are mounted thereon at opposite ends of the tie, only one of said rails being illustrated in the drawings, and adjacent to the inner edges of the rail said top plate is slotted, as at a on each side of the central web a to receive depending flanges on the inner railclamping members O.

Figs. 5 and 6 illustrate The rail is secured to the tie A by means of two rail-clamping members C and D, between which the rail is clamped. The inner clamping member C has a clamping portion 0, extending upwardly from its base portion 0 and so shaped and proportioned as to fit between the tread and base portions of the rail and bear against the web of the rail so as to firmly hold the rail against independent vertical movement. The base portion 0 of the clamp member C rests upon the base I) of the rail, and beyond the edge of the base portion of the rail it is provided with two depending flanges c and 0 which project through the slots 0 in the top plate of the tie A and extend sul'liciently below said plate to receive clamping-bolts E, which bind the tWo clamping members together. Between the flanges c and c the base portion 0 is provided with a rearward extension 0, which rests upon the top plate of the tie and serves to hold the clamping portion 0 firmly against the web of the rail and prevent it from being moved inwardly when the two clamping members are brought together for clamping the rail.

It will be noted that the shape of the clamping member C is such that it may be readily formed from aflat metal blank cut and bent to proper form; but I prefer to form said member from a rolled metal blank in the form of an angle-bar having a cross-section conforming to the cross-sectional contour of the clamping portion 0 and the base portion 0, with its extension 0, the angle iron or bar being cut into proper lengths to form the clamping member, the depending flanges c and 0 being formed by cutting and bending down a portion of the metal, as will be readily understood.

The rail-clamping member D may also be formed from a flat metal blank of proper shape; but I prefer to form this also from a rolled metal blank, the latter in this case being in the form of a channel-iron. Said clamping member D extends across the end of the tie A, and at each side it is provided with a flange (Z (Z, the two flanges embracing the side edges of the top and bottom plates of the tie and serving to firmly hold the clamping member against sidewise movement.

roo

Said clamping member is preferably made to member D is made to bear directly upon or, against the rail B, its bearing-face d should i be so shaped as to more or less closely fill the space between the tread and base portions of the rail; but as this would materially add to j the cost of manufacture I prefer to use the interposed bearing-plate F. Said bearingplate may be made from a flat metal blank or out from a rolledmetal angle-iron. Its railbearing portion f rests against the web of the rail, and its base portion f which is bent outwardly from the portion f, base portion 1) mg confined between said flanges against s1 ewise movement.

The two clamping members are drawn toheld in clamping engagegether and firmly ment with the rail by means of the bolts E, which are inserted through apertures in the depending flanges c and c of the clamping member 0 and through corresponding apertures in the clamping member D, the outer end of the bolts being provided with nuts 6 for drawing and holding the clamping members together, as will be readily understood.

The bolts E are provided with a square or polygonal head e, which bears against the under surface of the top, plate a of the tie A, as clearly shown in Figs. 1 and 4, the clamping-plate 0 being thus locked against vertical movement and the bolts E locked against rotation.

The bolt-apertures in the clamping member'D are preferably elevated slightly above the corresponding apertures in the depending flanges of the clamping member C, so

that the forward ends of the bolts will engage with the under side of the top plate of the tie, and thus more firmly hold the clamping member D against upward movement.

en the several parts of the devices are constructed and assembled as shown and described and the bolts E are tightened sufliciently to properly clamp the rail B, every part of the device will be firmly and positively held against independent movement.

The clamping member 0 is held against horizontal movement by the engagement of its depending flanges c and c with the walls of the slots a in the tieAand is locked against vertical movement by the'heads of the bolts E. The clamping member D is held against rests upon the of the rail and extends outwardly a sufficient distance to be engaged at its side edges by the side flanges d d of the clamping member D, said bearing-plate be-.

sidewise movement by its side flanges (Z (Z, which engage the sides of the top and bottom plates'of'the tie, and is held against upward movement by the bolts E and against downward movement by engaging with .the base portion f of the bearing-plate F. The bearing-plate F is held against vertical movement by the tread and base portions of the rail B and against sidewise movement by the side flanges of the clamping member D.

For locking the bolt-nuts 6 against rotation I have provided a nut-lock, which is at tached to the rail-clamping member D, said nut-lock consisting of a block or plate G, which is made to fit between said nuts when the latter are turned with their edges parallel to each other, as illustrated in Fig. 3. Said plate is suspended between the nuts by a link g, to which it is secured, said link being loosely connected at its upper end to the clamping member, as clearly shown in Figs. 1, 2, and 3, so that it may be readily lifted from between the nuts to permit of their ro tation and again placed in looking position, as will be readily understood.

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

1. The combination with a metallic crosstie, of rail-clamping members for securing a rail thereto, one of said clamping members being detachably secured to the cross-tie and having a portion extending below the same to form an anchor therefor.

2. The combination of a' metallic cross-tie, of a detachable rail-clamping member extending over the end of the cross-tie, and below the same to form an anchor therefor.

3. The combination of a metallic cross-tie, of rail-clamping members, one of which is secured to said tie, the other extendin over the end of the tie and being provided with side flanges which engage the sides of the tie, and clamping-bolts for drawing and holding said members in clamping engagement with a rail.

4. The combination of a metallic cross-tie having a central vertical Web and a horizontal top plate with a flat upper surface, said top plate having slots cut therein at opposite sides of said web adjacent to the edge of the rail to be secured thereto, a rail-clamping member having depending flanges projecting below the top plate of the tie through the slots therein, a cooperating clamping member, and clamping-bolts connecting the two clamping members below the top plate of the tie.

5. The combination of a metallic cross-tie having a central vertical web and a horizontal top plate with a flat upper surface, said top plate havin slots cut therein at opposite sides of said web adjacent to the inner edge of the rail to be secured thereto, a railclamping member for the inner side of the rail having depending flangesprojecting below the top plate of the tie through the slots therein, and having an extension which bears upon said top plate beyond said slots, a 00- operating clamping member extending over the end of the cross-tie, and clamping-bolts connecting said clamping members below said top plate.

6. The combination of a metallic cross-tie having a central vertical Web and a horizontal top plate with a fiat upper surface, said top plate having slots cut therein atopposite sides of said web adjacent to the inner edge of the rail to be secured thereto, a rail-clamping member having depending flanges projecting below said top plate through the slots therein, a cooperating clamping member extending over the end of said cross-tie, and clamping-bolts connecting said clamping members below said top plate, said bolts having their heads engaging with the under surface of said top plate for the purposes described.

7. The combination of a metallic cross-tie, of rail-clamping members for securing a rail thereto, one of said clamping members being secured to said tie, the cooperating member extending over the end of the tie and having side flanges which engage with the sides of the tie, a bearing-plate against which said 00- operating bearing member bears adapted to bear upon or against the web of a rail, said bearing-plate extending between the side flanges of said cooperating clamping member.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
