Specification of Letters Patent. Patented B131. 28,

Application filed July 6,1921. Serial No. 482,754.

To all whom it may concern:

Be it known that l, lVILLm-M HoUsroN,

- a citizen of the United States, residing at Vinnemucca, in the county of Humboldt and State of Nevada, have invented certain new and useful Improvements in Rail Clamps, of which the'following is a specification. I

This invention relates toimproved devices for preventing rails from creeping and spreading, the general object of the invention being to provide a chair adapted to be seated upon a tie and having spike'receiving holes therein for securing the chair to the tie and to the rail.

Another object of the invention is to provide abutnients on the chair for engaging the rail, one of which is removable and is secured in place by a spike.

A still further object of the invention is to provide serrations on. this movable abutment for engaging serrations formed in the edge of the rail base and a lug on said movable abutment for engaging a hole in the chair. a

A still further object of this invention resides in the provision of a rail clamp having a locking plate provided with serrations which are adapted to either mesh with similar serrations in the base of a rail or be forcibly embedded in the adjacent smooth edge thereof.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and 1n wh1ch2- Figure 1 is a plan view showing the -in-- vention in use.

Figure 2 is a longitudinal sectional view on line 2-2 of Fig. 1. v

Figure?! is an elevation of the rail-clamp with a rail shown in cross section thereon. Figure 4 is a fragmentary view of a part of the rail.

Figure 5 is a view of the movable abutment or looking plate.

Figure 6 is a bottom view of this plate.

of sufiicient length to extend under both rails. The drawing shows a chair of short length engaging but one rail and it being understood that there will be another chair under the other rail. This chair is provided with a pair of spike receiving holes 2 for receiving spikes for engaging the outer edge of the rail and a spike receiving hole 2 for receiving a spike for engaging the opposite'edge' of the rail. A lug 3 is formed on the plate adjacent said hole 2 for forming a bearing for the head of the spike. A hook-shaped lug 4 is also formed on the plate on each side of the hole 2 for engaging the rail base, as shown in Figures 1 and 3. Depressions 5 are formed in the corners of the plate at its inner end, the hooked lugs 4 extending out of these depressions. An elongated hole 6 is formed in the outer part of the chair or plate, the inner wall of this opening being beveled, as at 6.

A locking plate 7 is provided for engaging the outer side of the rail and this plate has a downwardly extending lug 8 on its lower face for engaging the hole 6, said lug having its inner edge undercut to engage the beveled wall 6 of the hole. A hole 9 is formed in said plate adjacent the lug 8 to receive the spike which passes through the outer end of hole 6. Lugs 9 are formed on the top face of the plate at opposite sides of the opening for forming bearings for the spike which passes through said opening. This plate 7 is provided with an extension 10 which is of less width than the plate so as to leave angle recesses 11 at the inner corners of the plate for receiving the spikes which engage the outer edge of the rail base. Extension 10 has its edge serrated, as at 12,

and serrations 13 are formed on the edge of the rail base to receive these serrations 12, or the serrations maybe formed 1n the rail base by the serrations 12 of the locking as it is forced into its working posi- -l'. A spike 14; is driven through the hole 2 into the tie so that its lip will engage the rail in the ordinary manner, between the hooked lugs l. The lug 3 will help to hold the spike against movement away from the rail. Locking plate 7 is placed on the outer part of the chair with its lug 8 engaging the hole 6 and its serrations engaging the serrations in the rail. A spike 15 is driven through holes 9 and 6 into the tie. This spike holds the locking plate in position and keeps the undercut wall of lug 8 hearing against the beveled wall 6 of hole 6. Spikes 16 are driven through the holes 2 into the tie with their lips engaging the rail base and their heads engaging the shoulders formed by the recesses 11.

- Thus the rail is firmly secured to the tie and it cannot spread or creep thereon.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is In combination with a tie and a rail, a chair having spike receiving openings therein for permitting the rail to be spiked to the tie, one of said openings being elongated, a locking plate a depending lug thereon for engaging a part of said elongated opening, the rest of the opening registering with an opening in the locking plate for receiving a spike, an extension on the plate having its edge serrated for engaging serrations formed in the rail, said extension forming recesses for receiving the spikes which engage the rail. j

In testimony whereof I affix my signature.

WILLIAM HOUSTON.
