Specification of Letters Patent.

Patented Dec. 14., 1909.

Application filed January 26, 1909. Serialflo. 474,225.

1 '0 all whom it may concern:

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 Railway- Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to railway fasteners and is designed as an im rovement upon the device'shown and descri ed in the patent to William Boyer, No. 895,949, and issued on- August 11, 1908, of which I am a joint owner.

This invention may also be considered as an improvement on, 'pr an adaptation of the forms of locking boltsshown in my pending applications, Serial No. 433,243, filed May 16, 1908, and Serial No. 461,403, filed Nov. 6, 1908.

It .is the object of the present. invention to simplify the construction of the securing devices shown in the patent to Boyer, re-

ferred to above, whereby the slabs or plates comprising the laminated steel tie maybe made as thin as possible, thus saving weight in handling and expense in manufacturing said slabs, and at the same time to provide means for securely holding the tie in place so that it will not slip on the road bed.

The invention consists in the use of a rotatable bolt which is provided with a laterally projecting lug adapted toengage the under surface ofthe tie, a head having a cam-shapedunder face adapted to clamp upon the foot of the rail, and a downwardly rojecting portion or extension adapted to be driven into theroad bed when the bolt is inserted through. the opening provided therefor in the tie and before said bolt is turned to clamp the rail. This bolt may also be used in connection with an ordinary wooden tie, in which case it is preferable to place a metal plate on thetop and bottom surfaces of the tie to hold the bolts up against the rail and prevent them from wearing away the wood which might happen if said metal plates were not used and result in the bolts slipping away and losing their grip upon the rail. The bottom plate also serves to protect the wood of the tie from engagement by the laterally extending lugs of the bolts and provides a non-yieldingsurface for them to bear against when the bolts are tightened. 3

The invention also consists in the features of construction and combinations of parts hereinafter described and specified in the claims.

In the accompanying drawing illustrating the preferred embodiment of. my invention: Figure 1 is a broken longitudinal vertical section of "a laminated steel tie showing a rail secured thereto by means of my improved fastener. Fig. 2 isa plan view thereof. Fig. 3 is a longitudinal vertical sectionalview of a wooden'tie showing the invention applied thereto. Fig. 4 is a detailed View of one of the bolts, Fig. 5 is a detailed view ofoneof the plates used with the wooden tie, and Fig. 6 is a broken sectional view showing a modification.

' Referring more particularly to the drawing, and first to Figs. 1 and 2 thereof, 1 designates the laminated steel tie which is here shown as being composed of three plates or slabs 1 1", and 1 It is of course understood that any desired number of plates or slabs maybe used for constructing 'thetie according to the strength required or the strain to. which it is to be subjected. Vertical key slots 2 are formed through the tie, one at each side of the foot ofthe rail 3.

The extensions 2 of the key slots are shown arran ed at the sides thereof farthest from the rail but they may extend parallel to the edge of the'rail or at any angles thereto desirable; L

One of my improved bolts 4 is arranged in each of the key slots with its laterally extending lug 5 engagin the bottom surface of the tie and the cam-s aped under face 6 of its head 7 clamping upon the foot of the rail.

The lower pro ect1on 8 of the bolt extends down into the 'roadbed,'as shown in Fig.1, thereby preventing the tie from moving or slipping from its proper position. A washer 9 maybe interposed between the foot of the rail and the head of the bolt. The washer may be made of various thicknesses to take care of any discrepancy between the lengthof the bolt, between its head and the lateral lug, and the thickness of thetie and foot of the rail. The washer may also have portions thereof-cut and bent up, as illustrated at 10, to engage serrations 11 in the periphcry of the head of the bolt to lock said bolt against reverse turning.

Each bolt is made sufficiently heavy and strong to permit its being driven into place with its downward extension 8 engaging the roadbed. The length of said downward ex tension of the bolt may vary to suit the physical condition of the roadbed, the cost of the material, etc. The head of the bolt is preferably formed with a square wrench-engaging portion 12 whereby it may be turned to obtain the desired clamping action after the bolt has been driven down into its proper position. When the bolt is driven 'in, its lateral lug 5 passes through the extension 2 of the key slot 2. As soon as said lug reaches a position below the tie, it is disengaged from the extension of the key slot and may revolve out of line therewith when the bolt is turned.

In Fig. 3, 13 designates an ordinary wooden tie to which. a'rail 1 f is secured by the same kind of fastener or bolt hereinbefore described in Connection with the laminated steel tie. Metal plates 15 are preferably placed on the top and bottom surfaces of the wooden tie to protect it and form bearings for the shanks of the bolts, the bottom plate also forming a bearing for the lateral lugs of said bolts. These plates extend across both of the key slots in the tie and are of course provided with corresponding openings 16 therein as shown particularly in Fig. 5. Said plates may be secured to the tie in any suitable manner, such as by having their corners bent up and driveninto said tie.

In Fig. 6, I have illustrated a modified form of bolt adapted to be used with a wooden tie without any top plate. This bolt is made with the upper portlon of its shank, that is, the part arranged within the opening in thetie, enlarged as at 17 while it is reduced in size where it passes through the the tie is round and of a size to opening in the bottom plate. The 0 ening in t the enlarged portion-of the bolt but the opening in the bottom plate is smaller and shaped like a key slot so that apart thereof extends inward beyond the edge of the opening in the tie, as at 18,.to provide a bearin for the projecting lug 19 which extends rom the reduced portion of the shank and terminates within the plane of the eripheral surface of said enlarged portion 0 said shank. It will be noted that in this construction the opening in the tie is filled by the enlarged portion of the shank in such a manner as to revent the bolt from slipping and that the olt is also heavier and stronger.. I claim:
