SPECIFICATION forming part of Letters Patent No. 488,195, dated December 20, 1892.

Application filed December 21, 1891- Serial No. 415,800. (No model.)

To aZZ whom it may concern.-

Be itknown that I, WILLIAM Gown 2. citizen of the United States, residing at West Bay City, in the county of Bay and State of Michigan, have invented certain new and usefullmproveinents in Railway-Rail Fastenings, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in fastenings for securing the rails to the ties or sleepers of a rail road, and the object of the invention is to furnish a substantial and secure fastening fora rail road rail, which, while holding the rail firmly in position againstia lateral and a lifting strain, can be easily and quickly removed and replaced for repairing the track.

Another object of this invention is to provide a rail fastening for rail roads, in which the holding down action and the resistance against a crowding strain, are brought to bear upon different parts of the device, whereby the devices for retaining the rail upon the tie are not disturbed by a lateral strain exerted upon the rail.

The first part of my invention consists in a blank for a rail clamp and brace, and composed ofa body portion provided with a centrally located elongated opening, and having a central tongue portion projecting from its opposite end portions, and provided on each lateral side of one of the central tongues with a side tongue having its outer ends cut to a V shape.

The invention consists, secondly, in a rail clamping device composed of a plate of metal with a body portion provided with an elongated opening for a bolt or spike and having a middle tongue portion of its front end bent upward and forward for reaching over the railflange, and with the lateral portions beside the tongue and also a reduced part of its rear end bent downwardly to a right angle with the body portion for driving into the tie. And the invention also consists in the combination, arrangement and form of construction of the several parts, and in the method of securing the rail to the tie as I shall presently proceed to explain, apd which will also be specifically pointed ouf'in the claims following.

My invention is illustrated in the accompanying drawings in the several views of which the letters and figures of reference will be found designating the same elements or parts, and which are to be considered as a part of this specification.

Figure 1, represents a transverse vertical section of a rail and tie and of my improvement in position for holding the rail. Fig.2, is a side view of the same in elevation with the securing nut removed. Fig. 3, is a plan view of ,the same. Fig. 4, is a'top view ofthe rail brace ready for use, andenlarged. Fig. 5, is a side View in elevation, and, Fig. 6, is a front View of the same. Fig. 7, isa plan View of the blank cut to form for bending to produce the brace. Fig. 8, is a vertical transverse section of the rail and tie, and of an implement for fixing my fastening device in place. Fig. 9, is a plan view of the brace in a modified form. Fig. 10, is side view of the same.

a, represents a rail road tie or sleeper of the common form laid transversely with the road bed, and b, is one of the rails laid across the tie in the usual manner. Atashort distance from the edge of the base flange c, of the rail, the tie is provided with a vertical opening d, and into this opening is passed, by driving the securing bolt 6. This bolt e, is provided on its lower portion which passes into the tie, with coarse threads f, which have an abrupt lead, so that in driving the part into the tie the threads will impinge into the side walls of the opening and cause the bolt to turn in driving so that when the bolt is in place the threads thereon will have an engagement with the walls of the opening which precludes its withdrawal therefrom without turning the bolt in the opposite direction. The bolt is provided at the upper end of the lower threaded portion with a part g, of rectangular form which when a withdrawal of the bolt from the tie is required, is in perfect form to receive a wrench for that purpose; directly above the portion 9, is arranged a shoulder h, the upper portion 2', immediately above the shoulder being of a cylindrical form and ofa slightly less dimension transversely than the portion below, and is provided with a thread j, of ths usual form and dimension for bolts of this form. The bolt is forced into the openor upsetting the upper end, the bolt turning in the opening m, to allow the threads f, to engage with the wood, and leaving the stud por tion 01, projecting above the tie surface. lhis bolt is preferably made by'first preparing a rectangular bar with a cylindrical threaded upper portion and the shoulder, and then forming the threadsf, on the rectangular portion' by twisting, to bring the former corners of the bar to the form of four spiral threads which have an abrupt lead and which easily enter the opening and engage with the walls thereof by turning the bolt as it passes into the tie.

0, is a rail brace and clamping device, and is composed of a plate of metalpreferably rolled, and cut to a blank as shown in Fig. 7, and consists of .a body portion 1, provided with an opening q, elongated longitudinally with the .plate, and with a tongue 1", projecting from one edge of the body and provided with a V point, while the opposite edge of the body is provided with the centrally located tongue 8, and with a tongue 25, on each lateral side of the tongue 3, each of the tongues 15, being provided with a V, point, with cutters for driving into the tie. In forming the clamp the central tongue .9, is provided with an upward and outward bend forming a shoulder u, for contact with the rail flange, and the lateral tongues t, and also the tongue 0", is bent downwardly to a right angle with the plate. The brace is placed in position with the opening q, passed over the stud c', of the bolt, and with the parts 25, against the lateral edge of the rail-flange, and the implement 7c, is then placed upon the stud with its face upon the body of the brace, and then a few blows of a hammer upon the implement k, forces the parts If, and 0", into the tie in a perfectposition with the tongue 5, reaching over upon the rail flange. A washer or spring nut lock '0, is then passed over the stud 71, upon the brace and a nut to is turned on the stud 1', above the nut lock and firmly clamps the parts in position.

For moving the brace to repair the track the nut w, is removed, and then the brace is free to be raised from its position, and the brace can then be removed or replaced as necessary, and for lifting the track slightly, the nut is turned partly off and a thin web can be placed between the rail and tie, and the nut againtightened down, or anew brace having a tongue portion 5, raised higher to coincide with the height of the rail flange from the tie can be substituted or whatever other changes in the brace portion found necessary can be made.

The bolt e, is designed as a permanent fixture in-the tie, the elongation of the opening q, providing for an outward movement of the brace without contact with or bearing against the stud, the downwardly turned portions 1, and t, of the brace receiving and providing the required resistance against the crowding strain upon the rail, so that the stud and the nut. thereon serves only for retaining the brace against a lifting action of the rail, or for retaining the brace firmly upon the tie.

From long use and contact with the moisture contained in the tie, the bolt is liable to corrosion on its contact surface,which has the efiect to retain the bolt more solidly and perma= nentlyin position and is an advantage so long as the parts are not too greatly weakened by the corrosive action, andin order to remove the bolt when corroded-and held against turning thereby, the tool is placed upon the stud and is provided which requires an immense strain to withdraw or loosen the bolt while for a lateral resistance the tongues r, and 15, provide a great area against the end grai'n'of' the timber for sustaining the rail againsta crowding strain, and the shoulder u, together with the upper front faces of the tonguest, provides a large surface to receive the chafing and abrading action of the edge of the base flange of the rail, so that it is at: once evident that a lengthy and superior service is obtained by Y the use of my improved fastening.

Of course it will be understood that while I have described the most convenient and sat-- isfactory method of constructing the improved fastening I do not limitmy invention entirely to the structure explained, as other forms of constructionsubstantially the same may be used if desired, and a' fastening upwardly projecting threaded stud, allowsseveral braces to be used in succession without disturbing. the hold of the sustaining bolt in the wood, as the bolt so long as it is not subjected to a crowding or lateral strain, is not liable to displacement, so that the perma= nency of the upwardly projecting stud isassured,and the mutilation and cutting out of the tie by the usual method of respiking the rail is altogether avoided, while at the same time a stronger and more'reliable fasteningis produced,

As shown in Figs. 9 and 10, the tongue 3, is formed with a greater thickness of metal than the portions 25, and the thickness of metal in the tongue 3, is carried across the body portion 19, forming a centrally located rib y, which provides a reinforce for the brace against bending from lifting the rail, and the part 7', may, in that case, be omitted if desired, and this form would be preferable for use with heavy rails as agreater thickness of metal is provided for resisting a heavy upward strain while the parts i, which enter the tie are of a thickness to drive easily and without mutilating the tie.

Having described my improvement what I claim as my invention is:

1. A blank for the manufacture of a rail road brace, consisting of a plate of metal having a body portion 19, provided with an elongated longitudinal opening q, and having the tongue port-ion r, projecting from one end and provided with a V, point and having extended from its opposite edge the lateral tongues 15, provided withN shaped points and a centrally located tong! is, substantially as and for the purpose set forth.

2. A brace for a rail road rail consisting of the bodyportion 10, having an elongated centrally located opening q, the downwardly turned tongue r, upon the rear edge of the body portion, and having on the opposite edge of the body an upwardly bent and forwardly extended central tongue 5, provided with a shoulder to, and with the downwardly turned tongue portions 25, on the lateral sides of the said tongue 8, substantially as and for the purpose set forth.

3. The combination of a rail-road rail and the supporting tie beneath the rail, provided with an upwardly proj ectingfixed stud having a screw thread, with a clamping device, having an elongated opening passed over said stud, and having a portion reaching over the rail flange, and downwardly turned portions driven into the tie, and a nut upon the stud above the clamping device, substantially as set forth.

4.
