Z'palbwhom, may concci'nl Be it known that 1 JULIUS T. Dn Sooonn'r,

a citizen of the United States, residing at Ohicage, in the county of (look and State of Illinois, have invented. certain new and useful Improvements in Iie-lP latos, of which the following is a full, clear, and sheet-specification.

lfllhis invention relates to improvements in 1 tieQplates interposed between railroad-rails I flanges or'ribs so arranged that when driyen into the tie they expose the resulting brokendown fibers to saturation by water from rain and other causes, rotting and deteriorating the tie and correspondingly weakening and reducingits stability so quickly and to such an ex tent as to permit an objectionable shifting movement of the tie-plates and require the turning of a tie before it is otherwise injured in order that a sound surface may be presen;

ed to the tie-plate, all of which is not only 0 bj ectionably expensive in time, but in money. I

The object of my invention is' a tieplate so constructed that the lateral movement of railroad-rails held down spikes is substantially, ifnot entirely, resisted by the tie-plate and that the fibers broken down b flangosor ribs-0n the tie-plate shall not be exposed to water or other elements tending to rot the fibers or reduce the stability of the f: tie-plate when in its operative position on the tie. a v

With these ends in viewrny invention. consists in certain features of novelty in the construction, combination, and arrangement of parts" by which the said objects and certain other objects hereinafter ap earing are attamed, all as fully desoribec with reference to the accompanying drawm s and more par tioularly pointed out in the c aim. in the said d rawinge, Figure 1 IS a perspective view of a t1e-plate embodying my 111vention with a part thereof broken away to'illustrate the constructionby which fibers broken down by the ribs or flanges are isolated from moisture and with a portion of the rail in its operative position on the tie-plate against the abutment thereof. Fig. 2 is alongitudinal section of Fig. 1 on' a line longitudinall of the tie-plate and centrally through the rib thereof. Fig. 3 is a transverse section on the the as great as when the pistonline 3 3, Fig. 2. Fig. 4 is a transverse section 55 Similar numerals of reference indicate the i same parts in the several figures of-the drawings.

wood tie havin 1 1ndicates an ordinar mounted thereon a tieQ'l a length, but of such Widt that its side flanges 3 may overlap and embrace the opposing 'sides of the tie, as distinguished from a tie-' plate narrowerin width and having its side flanges forced into the fibers of thetie. The flanges 3 when embracing the opposin sides of the tie preferably extend the entire ength te 2 of the usua'.

of the plate; but in tie-plates in which these tie-plates are narrower than the tie and the flw' ges are to be forced into-the fibers thereof the flanges to cover and isolate from moisture the fibers broken down and crushed by the flanges are sufficiently shorter than the tie-plate, asillustratcd in Fig. 5, to enable the plate proper to project sufficiently beyond forcing of the flanges into the body of the tie.

To further and more effectually isolate from moisture the. fibers broken down by the flanges, said flanges 3 may be-in the natureof ribs-that is to say, inset sothat the sides of the tie-plate will project outwardly beyond them; but whether so inset or not and whether or not the side-flanges are to be forced into the face of the tie, as illustrated in Fig. 5, or overlap the sides of the tie I also preferably provide the under surface of the,

tieplate with arib 4 parallelwith and inter meciate of said side flanges, which rib 4 is adapted to be depressedinto the fibers of the tie and terminate at a point inwardly removed. from. the ends of the tie-plate and a suflicient distance therefrom to enable the tie-plate to entirely cover and isolate frohi moisture. the fibers broken down idtorcing the rib 4 into the tie. 1 I By having the rib and the flanges shorter than the tie-plate their resistance when forced into the fibers of the tie to the lateral movement of the tie-plate is not only practically are extended to the ends of the tie-plate, ut the length of time they may so resist this lateral movement is substantially increased, for the reason that by the exclusion of moisture from thebrokendown fibers they are prevented from, softening and finally rotting, and thereby destroy tie-plate they will not deteriorate nor the tieplate loosen until the entire body of the tie is so nearly worn out that its reversal and the shiftin of the tie-plate will not be justified. As s own in the drawings, the rib 4 is triangular in cross section, as obviously the form of the rib and also the flanges?) when forced into the fibers of the wood is immaterial, exce ting so far as this forcing may be facilitated and it is within my invention to form the flanges and also the ribs in short and separated sections or in the nature of a series of teeth or points, if so desired. When the width of the tielate is such that the side flanges 3 embrace t e outer sides of the tie, said flanges may be curved or inclined, as indicated in Fig. 3, and forced to their operative position on-the tie after first slipping the plate on the end of the tie, or, if desired, said flanges may be of sufficient distance apart to rovide for dro ping the plate, so to speak, into place and a 'terward bending and forcing the points of the flange tightly against and even into the sides of the tie. On the other hand, the flanges 3 may be straight, as indicated in-Fi 4, or but slightly inclined, so as to be force downwardly into their operative position, as indicated b the construction shown in Fig. 4. The tie-plate is provided with the usual, preferably square, perforations 5, through which the s ikes 6 are driven into the tie for holding bot the rail and the tie-plate in their operative position and against moving or creeping longitudinally of the tie; but in order to relieve the body of the spikes 6 as much as possible from the pressure due to the lateral movement of the rails and'increase the effectiveness of the s ikes for resisting the movement of the tiep ates both laterally and longitudinally of the tie the lates embodying my invention are provided on their upper surface with ribs or other projections forming stops or shoulders 7, against which the outer edge of the 'base or flange 8 abuts when the tieplate, the

' rail, and the spikes are in their operative po sition, which stops are so constructed and arranged as to substantially, if not entirely, relieve the body of thesplke from any lateral Contact with the raiLflange, while at the same time the head of the spike fully performs its function of holding the rail down upon the tie-plate and the tie-plate upon the tie, and therefore against vertical movement. To

faces in a line with and may be in advance of the side walls of the perforations which are parallel with and adjacent the rail-flange, so that the lateral bearing of the rail-flange is substantially against the stops and not against the spike, or, in other words, so that the stops to the substantial'exclusion of the spikes resist the lateral movement and pounding of the rail, and to these ends the sto or stops 7 may be of any desired form an arrangementthat is to say, may consist of raised rib-like projections extendin entirely across the tie-plate, but sectioned by the spike-perforations in the plate, or such stop may consist of a single enlarged lug or bar or a series of bars at a right angle to and projecting against the edge of the railflange, for my invention broadly includes any stop device on the upper su face of a tie-plate, however formed or arranged, forming a bearing for the rail-flange or its web and by which the moisture tending to rot the fibers broken down by the "ribs my invention extends to and includes side flanges of the tie-plate, whether one or both embrace the outer sides of the tie, and also asimilar tie-plate narrower than the width of the tie on which it is placed.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is- I A tie-plate rovided with flanges projecting downwardly and inwardly over upon and closely embracing the tie upon which it is used and having ribs provided with cutting edges on its under face at a point intermediate said flan es, said ribsterminatin at points inwardly removed from both on s of the'tie-plate, said tie-plate being also provided with spike-holes and having on its upper face a transverse rib or ribs, the bases of which project inwardly beyond the inner walls of the spike-holes, whereby a tie-plate closely embraces both sides of a tie, moisture I is excluded from the broken-down fibers thereof and the lateral thrust of the rail is re- JULIUS T.
