FRANK SMITH, OF LINDSEY, OHIO.

TR'ACK-FASTENING.

SPECIFICATION forming part of Letters Patent No. 795,071, dated July 18, 1905.

Application filed April Z7, 1905. Serial No. 257,611.

To @ZZ whom, it ntcty concern:

Beit known that l, FRANK SMITH, a citizen of the United States of America, and a resident of Lindsey, county of Sandusky, State of Ohio, have invented certain new and useful Improvements in Track-Fastenings, of which the following is a full and clear specilication, reference being had to the accompanying drawings, in which- Figure l represents a vertical longitudinal section of my device applied to a tie of ordinaryconstruction, the tie being partlybroken away to show the anchoring-bolts; Fig. 2, a plan view of the same; Figs. 3 and 4, detail perspective views of the rail-clamping plates; and Fig. 5,a transverse section on the line 5 5 of Figl.

The object of this invention is to provide an improved rail-fastening device which will not only avoid the necessity of spiking the rails to the ties, but which will also effectually prevent spreading of the rails and serve las an efficient means for quickly gaging the track, as more fully hereinafter set forth.

To the accomplishment of this object and such others as may hereinafter appear, the invention consists of the parts and combination of parts hereinafter described, and particularly pointed out in the appended claims, reference being had to the accompanying drawings, forming a part of this specification, in which the same reference characters designate like parts throughout the several views.

Referring to the drawings by letters, a designates the tie, b the rails, and c the main railsupporting clamp-plates, these plates being fastened to the tie so that the rail shall rest thereon and each plate being provided at its outer end with a lip c, which engages the -outer flange of the rail.

Each of the chair-plates c is slotted longitudinally at g inside of the rail, and passing through this slot is a long bolt c', which eX- tends entirely through the tie, its head engaging the under side thereof and its upper threaded end passing up through the slot g and being provided with a nut. The upper threaded end of this bolt also passes through a longitudinal slot e in a plate d, which is clamped down on plate g by the nut on bolt e and which is provided at its outer end with a lip d', which engages over the inner flange of the rail. The plate d is provided with another longitudinal slotj'between the bolt e and the inner end of the plate, and passing through this slot is a short boltj". rl`his bolt f passes up through slot g and the slotjI and is provided with a nut on its upper end which clamps down on the upper face of plate d and assists the bolt e. in clamping the plate d in its adjusted positions. This bolt f is prevented from rotating and sliding in the slot g by having its head countersunk in the under side of the chair-plate c, as shown more par ticularly in Fig. 5.

The inner end of each chair-plate is provided with an upturned lug 7L, which is provided with a threaded opening h, the threaded opening in one lug being in line with that of the other. Screwed into these openings are the opposite ends of a reversely-threaded bolt c, which is provided with an angular en-` largement or head 7c about midway its length for the reception of a wrench. Lock-nutsm are screwed on the threaded parts of the bolt k and are adapted to impinge against the inner faces of lugs h, and thereby lock the adj usting-bolt in its adjusted position and prevent it being jarred loose.

By loosening the nuts on bolts e it will be observed that the rails may be spread farther apart or drawn nearer together by sim- -ply turning the adjusting-bolt 7C one way or the other. This adjustment of the rails, it will be observed, is accomplished without loosening or removing the clamp-plates d, the short bolts j" being allowed to remain tight; but if it be desired to adjust either of the clamp-plates d this may be readily done by loosening the nuts on both the long and the short bolts.

lt will be observed that my track-fastening avoids altogether the use of the usual spikes and will permit the use of old ties which will no longer hold spikes, new ties being necessary only every eight or ten feet to give the track-holder a firmer support than the old ties afford. It will be observed also that with a tie-holder constructed like mine it will be possible to use concrete, cement, or other IOO ties. The contacting faces of the plates d and c may be transversely corrugated to prevent them slipping.

It Will be apparent to those skilled in the art that various mechanical embodiments of the invention are possible, and I therefore do not Wish to be limited to the exact arrangement and construction shown.

What I claim, and desire to secure by Letters Patent, is-

l. In combination With a tie, a pair of chair-plates provided With means at their outer ends for engaging the outer langes of the rails and slotted longitudinally at points Within the rails, an adjusting reverselythreaded bolt connecting the inner' ends of these chair-plates, lock-nuts on this bolt, a slotted clamp-plate on each chair-plate and provided with a lip engaging the inner flange of the rail, a short bolt clamping each pair of plates together, and a longer bolt clamping each pair of plates together and to the tie, substantiallyT as set forth.

2. In combination with a tie, a pair of chair-plates resting on the tie and adapted to support the rails and provided at their outer ends with means engaging the outer flanges of the rails, each oi these plates being slotted at a point inside of the rail, means for adjust-
