TIE-PLATE Specification of Letters Patent.

Patented ma 11, 1909.

Application filed May 5, 1908. Serial No. 480,992.

To all whom it my concern: Be it known that I, MILTON BARTLEY, a citiburg, in the county of Allegheny and State of Pennsylvania, have invented certainnew and useful Improvements'in Tie-Plates, of which the following is a specification, reference bein s.

Ily invention refers .to an improved tie plate and spike holder for rails, and is designed to provide .a device adapted to be fiXedly'set on the tie, provided with means for engaging the edgeof the outer rail flange, and having securing spike openings and means for positively holding the spike in place against accidental removal or loosenin under the strains and vibrations of continue( use.

The invention consists of a plate, preferably of rolled metal, having along one or both lower edges "downwardly extending securing projections adapted to be driven into the tie, an upwardly extending lateral flange-retaining abutment, oppositely arranged spike receiving ogenin s and laterally extending tongues a apte to be bent over to en age the spike heads after insertion to retain them in osition. p

n the drawings illustrating the inven- -tion:Figure 1 is a plan view of a portion of a tie and rail showing my improved plate in osition. Fig. 2 is. a sectional elevation of Fig. 1. Fig. 3 is .a similar view at right angles to Fi 2. Fig. 4 is an enlarged plan view of the p ate. Fig. 5 is an edge view .of Fig. 4. Fig. 6 is a similar view at right angles to. Fig. 5. Fig. 7 is a sectional detai view on the hne VII; VII. of Fig. 4. Fig. 8 is a similar View showing a modified construction. I Fig. 9 is a sectional viewwn the line IX. IX. of Fig. 4. Fig. 10 is an enlarged sectional view on the line X. X. of Fig.

2is the main body of the plate, rectangular in form, having along its opposite lower edges downwardly projecting tapering ridges or blades 3 ada ted to be driven into the tie 4 lengthwise 0 its grain, and along one or both of its upper transverse edges alongitudinal abutment 5 for retaining engagement of the flange 6 of rail 7.

Extendin laterally of the plate, preferably housings 8 having spike openings 9, preferably rectangular in form to receive the shank of the spike, and provided with terminal lugs or tongues 10. These tongues are referably bent upwardly at any suitable ang e as indicated in Fig. 5 to facilitate final turnin overtie and the rail is set in place and thespikes driven in, the tongues 10 are finally bent over into embracing engagement, as shown in Figs. 2 and 10, thereby positively and effectively retaining the spike against removal except by force. The tongues 10 are referably narrowed or tapered as shown to a mit of the insertion of a claw bar or withdrawing tool under the sides of the spike head, and by originally turning the tongues 10 artially up in the manufacture of the plate, t ey may be more readily turned completely over u on the spike heads by a hammer in the nal operation. When thus secured, the spikes are positively retained in position against removal by jarring or in anymanner otherwise than by first forcibly turning back the retaining tongues 10, which may be readily done by the workman, after which the spikes may be taken out if desired. In service, the plate is held solidly down upon the tie, not only by the spikes and theretaining rojections entering the wood, but also y the weight of the rail; and the device as a whole will be found to effectually prevent the com- "mon well known trouble of loosening of the ering cross section, as indicated in dotted ines, and then turning them down at right angles in the same operation of shearing and bending the other parts. These blades may also be originall rolled in their right angle arrangement wit equal facility.

In manufacture, the device is referably made from continuous rolled blan s sheared off, punched and bent to produce the, construction described, at a minimum cost, re-

sulting, in a device of great efficiency, durability and simplicity.

, It will be understood that the number'or arrangement of the spike recesses and tongues may be varied, as well as other roportions, features or details, by the sk edv mechanic; but all such changes are to be considered as within the scope of the following claims.

What I claim is: 1. A tie plate consisting of a rectangular integral metallic body portion having its oposite edges turned downwardly and tapered or driving into a tie and its intervening transverse edge portion bent upwardly to 1provide a rail retaining abutment, said plate ing flange retaining rib extending transversely along one of the sides of the plate at right angles to said portions, an outwardly extending apertured spike receiving portion located at one end of said rib and wlth the rear edge of its a erture in alinement with the inner edge of t e rib, saidspike receiving portion having a narrow spike holding extension extending upwardly and outwardly from its outer portion and adapted to be bent over the head of the spike when in position, and a similar spike holding extension located at the opposite diagonal portion of the plate provided with a similar terminal member, substantially as set forth.

In testimony whereof I aiiix my signature in presence of two Witnesses.
