Specification of Letters Patent.

Patented Nev. 22, 1910.

Application filed August 4:, 1910. Serial No. 575,591.

To all whom it may concern:

Be it known that I, DAVID H. MARTIN, Jr., a citizen of the United States, resident of Harrisburg, in the county of Dauphin and State of Pennsylvania, have made a certain new and useful invention in Means for Fastening Railway-Rails and Preventing the Spreading Thereof; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a side view of the invention applied. Fig. 2 is a plan View of the same. Fig. 3 is a section on the line 3-3, Fig. 1. Fig. 1 is a section on the line .9-4, Fig. 3.

Fig. 5 1s a detail perspective view of the lever block. Fig. 6 is a detail perspective view of the stop block. Fig. 7 is a similar view of one of the bolts connecting the lever blocks with the surface plate. Fig. 8 is a detail perspective view of the spreader tie showing the same spiked to the railway cross tie.

The invention has relation to rail fastening devices to secure the rail to the tie, and in connection therewith means for preventing the spreading of the rails, both the fastener means and the spreader tie being designed to be of practical and durable nature, capable of being easily and expeditiously made at small cost.

In the accompanying drawings, illustrating the invention, the numerals 1, 1 designate the two rails, 2 the wooden cross-tie, and 3, 3 the metal surface plates between the rails and the tie and spiked to the tie at 8 3 For the purpose of fastening the rails to the tie I provide at each side of each rail a block 4, having at one end portion a flange 5, closely engaging the rail flange, andv at its opposite end lower teeth 6 parallel to the rail and located as a whole at an inclination to the horizontal, said teeth 6 having engagement with upper teeth 7, also located as a whole at an inclination to the horizontal and forming a part of a stop block 8 having a depending lug 9 detachably engaging an aperture or slot 10 in the surface plate 3 to maintain the stop block in position. The block 1 is hollowed out from below at 11 between its toothed portion and a transverse lug 12 located just in rear of the flange 5 and separated by an interval 5 from the surface plate. fin interval 8 separates the stop block 8 from the lug 12 of the block l, the hollowed out portion 11 being located at this )oint.

A bolt 13 engages a slot 1 1 of the block 4: and is provided with an elongated lower head 15, which in application is passed through a slot 16 of the surface plate and turned at right angles to engage the lower side of the surface plate at the sides of the slot, the nut 17 being then engaged with the threaded upper end of the bolt and turned to bear upon the block 1-. The shank of the bolt has a squared portion 13 adjacent to its head and fitting closely within the slot 1 1- to preventturning of the bolt when adjusted to position.

Thus the clamp bolt 13 takes a bearing upon the block 4 centrally of the length of said block, which in its turn takes a fulcrum bearing upon the stop block 8, with which it has toothed engagement, to press down the flange 5 against the flange of the rail, the block 1 acting as a lever. Lateral movement of the rail is resisted by the block a, which in moving must ride up the inclined toothed plane of the stop block 8, against which it is held down by the bolt and nut. A very secure clamping engagement of the block 1 with-the rail flange is the result.

The flange 5 of the block l engages the entire width of the rail flange and abuts at its end 4 against the web 1 of the rail, the lug 12 bearing at 12 againstthe free edge of the rail flange, this block being capable of adjustment by loosening the nut of the bolt 13, when it may be shifted forward or back one or more teeth as may be required.

The metal surface plates 8, 3 upon each tie, with which my rail fastening means has engagement, are connected together by means of a spreader tie-bar or rod 18, having at opposite ends thereof upward extending hook lugs 19, 19, turned inward or toward each other and passing through slots 20, 20 at the inner end portions of the surface plates, which are offset upward as shown at 21, 21 for this purpose. The tie bar or rod may also be spiked to the tie as shown at 18*.

In this way not only are the rails firmly held down to position, but they are also prevented from spreading. The necessary slots of the metal surface plates are readily punched therein, and the toothed fastener blocks are readily cast, the tie-rod between the surface plates being also of simple nature easily manufactured.

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

1. In a rail fastener, the combination of a surface plate, a stop block having engagementwith said surface plate to hold it in position and an inclined surface, a rockable lever block having an interval between the same and said surface plate, a bearing at one end adapted for fulcrum engagement with the rail flange, and at its opposite end an inclined surface for engagement with the inclined surface of said stop block, and a clamp bolt connecting said lever block intirmediately of its length with said surface p ate.

2. In a rail fastener, the combination of a surface plate, a stop block having an engagement with said surface plate to hold it in position and a toothed inclined surface, a rockable lever block having an interval between the same and said surface plate, abearing at one end adapted for fulcrum engagement with the rail flange, at its opposite end an inclined toothed surface for engagement with the toothed inclined surface of said stop block, and an intermediate perforation, and a clamp bolt engaging said perforation and connecting said lever block with said surface plate.

3. A rail fastener having in combination a metal surface plate having a plurality of slots, a stop block having a depending lug detachably engaging one of said slots, a lever block having an inclined plane toothed engagement with said stop block, a bearing upon the flange of the rail and a clamp bolt having an elongated head detachably engaging another of said slots of the surface plate and detachably connecting said lever block and saidsurface plate.

4. A rail fastener having in combination a metal surface plate having a plurality of slots, a stop block having a depending lug detachably engaging one of said slots, a lever block having at one end portion there of an inclined plane toothed engagement withsaid stop block, and a bearing at its opposite end portion for engagement with theflange of the rail, and a clamp bolt located intermediately of the length of said lever block and having an elongated head detachably engaging another of said slots of vend portion thereof an the surface plate and detachably connecting said lever block and surface plate.

5. A rail fastener having in combination a stop block, and a lever block having at one inclined plane toothed engagement with said stop block and at the opposite end portion thereof a bearing for engagement with the flange of the rail, and a clamp bolt located intermediately of the length of the lever block and capable of connecting the same with the railroad cross tie, said lever block having an end bearing for engagement with the web of the rail, and a depending lug having a bearing for engagement with the free edge of the rail flange.

G. A rail fastener having in combination metal surface plates having a plurality of slots, and upward offset inner end portions provided each with an aperture, stop blocks having each a depending lug detachably engaging one of said slots, lever blocks having an inclined plane toothed engagement at one end portion thereof with said step blocks and at the opposite end portions thereof a bearing for engagement with the rail flanges and clamp bolts having each an elongated head detachably engaging another of said slots of the surface plates and detachably connecting the lever blocks and the surface plates, and a spreader tie rod having upturned lugs detachably engaging the apertures of said upward offset portions of the surface plates. 7 7. A rail fastener having in combination metal surface plates provided with upward offset inner end portions provided each with an aperture, stop blocks having detachable engagement with said surface plates, lever blocks having each an inclined plane toothed engagement at one end portion thereof with said stop blocks and at the opposite end portion thereof a bearing for engagement with the rail flanges, and clamp bolts located intermediately of the length of the lever blocks and having detachable engagement with said surface plates, and a spreader tie rod having upturned lu 's detachably engaging the apertures of said inner end portions of the surface plates.

In testimony whereof I aflix my signature, in presence of two witnesses.
