TIE-PLATE.

Specification of Letters Patent.

Patented May 5, 1914.

Application filed June 6, 1910. Serial No. 565,320.

To all whom t may concern."

Be it known that I, EDWARD L. ADREON, Jr., a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Tie-Plates, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to tie plates, my object being to construct a tie plate which is especially designed to be used as a double tie plate in connection with a guard rail and a split switch, whereby the plate is securely looked to the rail.

My special object is to construct the tie plate for use with a screw spike, the screw spike opening being provided with a yielding bracing wall which permits the spike to be completely seated, and when seated the wall or backing forces the screw spike up to the rail, thus prevent-ing any lost motion.

To the above purposes, my invention consists in certain novel features of construction and arrangement of parts which will be hereinafter more fully set forth, pointed out in the claims, and illustrated in the accompanying drawings, in which Figure 1 is a top plan view of my invention; Fig. 2 is a section taken on the line 2 2 of Fig. 1; Fig. 3 is a section taken on the line 3 3 ofFig. 1, showing my invention whenapplied to' double guard rails; Fig. 4 is a top plan view of a modified form of the bracing wall for the screw spike; Fig. 5 is an end view of Fig. 4; looking in the direction ofthe arrow 4t; Fig. G is a top plan view showing a split switch tie plate constructed according to my invention; and Fig. 7 isa section taken on the line 7 7 of Fig. 6, showing my invention when applied to the main `rail with the split switch in position on the raised portion.

As heretofore stated, one of the essential features of my invention is the yielding backing for the screw spike. This backing is formed integral with the shoulder of the tie plate.

Referring by numerals to the accompanying drawings: 1 indicates the tie plate proper, which is preferably cast from malleable iron, and, as illustrated,is especially designed as a double tie plate, to be used in connection with a main rail and a gnard rail. However, the same principle of construction may be employed so as to make the tie plate for use as a single plate. Formed on one end of said tie plate is a shoulder 2, and on the opposite end is a shoulder o. Formed on the plate opposite the shoulder 2 are lugs t and 5, which are capable of being bent over the edge of the base flange of the rail, and formed on said plate opposite the shoulder 3 are similar lugs G and 7, capable of being bent over the edge of the base of the rail, and formed intermediate of the lugs 4 and 5 and 6 and 7 is a screw spike opening 8. The ends of the plate are provided with screw spike openings 9 and 10, and surrounding these openings on the outside are yielding walls 11 and 12. The yielding wall 11 is formed integral with the shoulder 2, and the yielding wall 12 is formed integral with the shoulder 3.

The spike openings 9 and 10 flare outwardly; that is, they are greater in diameter at the bottom than at the top, as illustrated in Fig. 3, thus permitting the yielding bracing lug back of the screw spikes to give or yield as the spike is seated, the objectl of these walls 11 and 12, as heretofore stated, being to hold the screw spike up to the rail.

It will be seen from Fig. 1 that the screw spike openings 9 and 10 project inwardly beyond the inner walls of the shoulders 2 and 3. The object of the projections 4, 5, 6

and 7 is to prevent the rail from lifting or canting. These are formed, as heretofore stated, s0 they can be bent over the edge of the base of t-he rail or they can be cast, in thek first instance, in hook form to receive the edge of the base of the rail.

In Fig. l I have shown the bracing wall 13 of the screw spike opening slit or made in sections. This is preferable when the wall is thick and does not yield readily.

In the construction shown in Fig. 1, the

bracing walls are made comparatively thin,

In Fig. 7 I have shown the screw spike and its yielding backing lug forcing the inain rail 14 against the riser plate 15, with the hooked lug 16 bent over the edge of the base of the rail 14. The walls 11, 12 and 13 partially surrounding the spike openings, as heretofore stated, are for the purpose of holding the screw spike up to the rail while the screw spike is being seated, and to keep the shank of the screw spike from backing away from the rail base when the spike is fully seated, and also to forni a partial support for the spike head when the saine is under tension or fully seated.

I claim:

1. A tie plate provided with a rail bearing surface and a downwardly and outwardly flaring passage-way for a screw spike, the upper portion of the wall of the passageway capable of being expanded by a screw spike as the same is being seated, and gripping and binding the screw spike adjacent and beneath the head when it is seated, thus preventing the spike from loosening by vibratio-n.

Q. A tie plate, provided with a spike opening, a yielding bracing wall arising from the opening, the said bracing wall being slit to form practically ndependentsections. 3. A tie plate provided with a rail-bear ing surface, a shoulder projecting from the top surface of said plate, said plate having a screw spike opening set back from the rail line of the shoulder, a yielding bracing wall integral with said shoulder, and a lug arising fro-in the top surface of said plate opposite said shoulder, said lug capable of being bent over the edge of the base of the rail.

4. A tie plate provided with two railbearing surfaces adjacent each other, a transverse shoulder projecting from t-he top surface of each end of said plate, said plate having a screw spike opening, a bracing lug arising from the top surface of said plate' and formed integral with said shoulder, a double set of lugs arising from the top surface of said plate between said rail-bearing surfaces, said lugs capable of being bent over the edges of the bases of the rails lo cated on said rail-bearing surfaces, and there being a spike opening formed through said plate between said lugs.

5. A tie plate provided with two railbearing surfaces, one arranged above the other, a transverse shoulder arranged adjacent the lower surface, there being spike openings formed through said plate adjacent said shoulder, and there being spike openings fornied through said plate adjacent the higher surface, and a lug projecting from said plate adjacent the shoulder formed between the lower and higher surfaces, said lug capable of being bent over the edge of the base of the rail.

6. A tie plate having a transverse rail bearing shoulder on its upper surface and there being a spike opening in the line of said shoulder, said spike opening having an upwardly projecting and yielding riin flange surrounding the rear and sides, but not the fro-nt portion thereof, and said flange forniing a backing for the shank of the spike to prevent it from backing away from the rail while being seated, and a partial support for the head of the spike when fully seated and under tension.

In testimony whereof, I have signed my naine to this specification, in presence of two subscribing witnesses.
