Specification of Letters Patent.

Patented as. e, 1915.

Application filed March 16, 1914. Serial No. 825,034.

Be it known that I, CHARLES H. CORNELL, a citizen of the United States, residing at Valentine, in the county of Cherry and .State of Nebraska, have invented certain new and useful Improvements in Rail- Fasteners, of which the following is a specification.

This invention relates more particularly to means for fastening railway rails to cross ties and holding them securely position.

Among the objects of this invention are: to provide a simple and eflicient device of the character indicated; to provide such a device which may be readily and economically manufactured, and which will be cilicient and durable in operation; and in general, to provide such an improved structure as will be more fully described herein: after.

Inthe accompanying drawings illustrating my invention: Figure 1 is a cross sectional view of a rail showing a preferred form oit'my device in locked position, at the left hand side, and in its initial position on the right hand side; Fig.2 is a plan view of the same; Fig. 3 is a bottom view of the samegsli ig. 4 is a detail of the bolt and looking member; Fig. 5 is a plan View of the locking member; and Figs. 6 and 7 are details showing a modified form of construction. F

In accordance with my invention, a railway tie such as shown at 8 in the drawings is provided with holes 9 on either side of the rail 10, for receiving the fastening bolts 11.

The tie is provided with a bottom plate 12,

and is preferably provided with a top plate 13, upon which the rail rests. The locking bolt 11 is preferably tapered or reduced at its lower end which lessens the weight there of, andalso permits the forming of one or more fastening lugs or projections 14 at the lower end thereof, and the total length of such lugs or projections preferably will not exceed the diameter of the bolt. These lugs or projections are formed for the purpose of locking the bolt to the lower plate 12. In the forms shown particularly in F i gs. 1 and 3, these projections form substantially a locking button which may be passed down. through a slot 15 in the plate 12, and then turned substantially 90 to locking position. The lower surface of the plate 12 is provided with depressions 16 at substantially right angles to the slot 15, for receiving the lugs 14: after the bolt has been inserted and turned. The locking bolt 11 is provided at its upper end with any suitable form of head such as indicated at 17, for receiving a wrench to hold it in position while the pressure or locking device 18 is being turned. This pressure or locking device comprises a washer-like member, with its lower surface made in the form of a helicoidal cam or screw 19 and provided with means, such as the angular, upwardly extending portion 20 for turning the same. This angular por tion is preferably made in a standard size, so that the locking member can be turned with a wrench. This locking device 18 is provided with a hole 21 which is sufficiently large to allow the passage of the projection on the lower end of the bolt, and will fit the upper end of the bolt fairly close. The

outer periphery of this member is provided with a plurality of slots or indentations 22 for engagement by a nail 23, which is used for holding the device in locked position. This cam washer may engage directly with the lower flange of the rail 10, or a clip or plate 24 may be placed with one end resting on the plate 13, and the other resting on the flange, so that when the washer is turned to locking position, it will press this plate against the flange.

When a rail is to be locked in position, the bolt 17 is provided with a locking cam 18 as indicated, and its lower end is passed down through the slot 15 in the plate 12. The clamping plate 24 is then placed in position and the cam washer 18 may be turned by hand until it engages closely with plate 24, for instance as seen at the right hand side in Fig. 1. Then by applying a wrench to the angular portion 20, the cam washer may be turned until it presses the plate 24 tightly against the rail flange, and will fasten rail to the tie. The depression 16 in the plate 12 will prevent the turning of the bolt,

In the modified form of construction shown in Figs. 6 and 7, the bolt 25 is made with an angular section, preferably square,

as indicated at 26, to engage with a square readily seen that, if the bolt becomes injured, the cam washer may be utilized with another bolt. Furthermore, these cam washers maybe made in different sizes, so that if one washer will not lock the parts sufficiently tight, another one may be used, thereby giving a convenient means of adjustment. If the ties become shrunken, or

if the fastening device becomes loosened onaccount of wear, they may readily be turned within their limits of cam adjustment, in order to take up for the wear or looseness. Then if a further takeup is necessary, a new cam washer may be used, or a thicker clip or plate inserted. From this descriptionit will be readily seen that I provide an exceedingly efiicient and durable rail fastening device which may be readily applied,

I and which has the advantage of protecting the ties rather than injuring them, as oc curs with the common forms of spikes.

It will also be observed that changes may be made in the particular form or arrangement of my device without departing from the spirit of this invention, and therefore I do not wish to limit myself to the exact construction shown and described, except as specified in the following claims, in which I claim:

1. The combination of a tie having a hole therethrough, a plate under said tie having a slot in alinement with the hole through the tie and having depressions at the sides of the slot, a bolt having a locking end adapted to be inserted through theslot and turned to engage with the dept sions, a

rail, and a cam washer rotatably engaging with the upper end of the bolt, with its cam surface engaging with the lower flange of the rail.

2. The combination of a railway tie, an upper plate on said tie and rail resting on said plate, said plate and tie having a hole therethrough, adjacent to the rail, a lower plate having a slot in alinement with said hole, and having a depression in its lower surface arranged transversely to the slot, a bolt having a lug at its lower end adapted to be passed through the slot and turned to engage with the depression in the lower plate and having a head at its upper end, a locking member rotatably engaging with said bolt and having a camlike lower surface for locking the rail in position, and also having an upwardly extending portion adapted to be engaged by a wrench for turning the same, said locking member also having a plurality of recesses in its outer periphery, and a nail engaging with the tie and passing through one of said recesses.

3. The combination with a fastening bolt for a rail, of a removable locking member having its lower surface made in the form of a helicoidal cam.

4. The combination with a fastening bolt for rails having an angularly formed upper portion, of a locking member, having an angularly shaped hole therethrough for engagement with the bolt, and having a camlike lower surface for engagement with a rail or the like for pressing the same down.

5-. The combination of a tie, a plate on the lower surface of the tie, a bolt passing through said tie, means for locking the lower end of the bolt, to the plate, a rail, a clamping member engaging with the flange of the rail, a cam washer rotatably mounted on said bolt, having its cam surface engaging with the clamping member, and means for holding said washer in adjusted position.
