4 Claims.

My invention relates to improvements in tie plates and it more especially consists of the features pointed out in the claims. J

The purpose of my invention is to produce tie plates from single flat plates by die press stamping; that provides raised projections on the upper surface of the plate by pressing corresponding recesses on the under side of the plate so as to maintain the structural integrity of the plate; that forms a cant on the upper surface over'a central area of the plate; that combines a camber with the cant so as to produce a curved face for the rail to rest on; that in one form provides supporting projections for rail holding washers; that in another form produces rail positioning ledges pressed up from the body of the plate; and that in the latter embodiment a co-mbinedcant and camber is formed between the rail positioning ledges. The exemplification shown in Figs. 1-6 includes the special rail fastening means cmbodied in applicationSerial Number 558.396.

With these and other ends in view I illustrate in the accompanying drawings such instances of adaptation as will disclose the broad underlying features of the invention without limiting myself to the specific details shownthereon and described herein.

In producing and installing my improved tie plates I may use whatever alternatives or equivalents of structure that the exigencies of varying conditions may demand without departing from the broad underlying features of the invention.

It has been proposed heretofore to form tie plates with a canted upper surface running from end to end of the plate crosswise of the rail length by rolling methods and also formthe camber crosswise of the plate fromoneedge to the other parture from this practice by pressing up the central portion of theplate to ,form the sloping and cylindrical curved upper .faceof theplate by pressing the material up Ifromthe .undersideari d avoiding the defect of running the cant and camber to theedges of the plate. Such a rolling operation is quite expensivebecause special rolls mustbe made for each change in sizelandsty'le of tie plate. Furthermore, it is .wellknown that it is not practical to securea uniformly shaped plate byro-lling the camber in it.

It has also been attempted to press a camber in a punch press with the curve of the camber forming a true arch from one edge of the plate to the other. Without a reinforcing between the margins of the camber and. theedges ofthe plate it .does not possess the required .ri lqi y. This causes it to soon flatten out under the recurring vpoundingof heavy traffic. In my methodonl'yfthe center of theplate is canted or cam bered as desired or both configurationsmay be made on .a single plate. Inthisway the opposite edges of the plate are made parallel with each other thus producing adie plate that at all times will lieflat onthe tie andthe raisedcenter poi tion wilLnot.become flattened under the heaviest loads of railway traflic. Plates embodying my invention may be nanufactur'ed at less cost than other forms in use at thepresent time. *In addition theycan be made more uniform in every way. The same advantages of pressing up the cant or camber from the body of the plate over a central portion only enables me to produce the by the same method. I havemade a radicaldeordinary type of tie plate which is held in place by means of driven spikes.

The exemplification illustrated in Figures 1-6 inclusive comprises a flat plate 1 provided with holes 12 for securing it to the tie by means of screw spikes or otherwise. of the plate has a lengthwise cant 2 formed with its lowest point at 3 and its highest point at 4. Likewise the same area may have a curved contour or camber 5 crosswise of the plate and lengthwise of the rail (not shown). The cant 2 or camber 5 is formed so as not to reach the side edges of the plate. This leaves a flat margin along side of the raised center. In this type of plate special rail fastenings are shown, that is, the projections on which fastening washers (not shown) are attached. These projections include raised bosses 6 adjacent the center area and raised supports 9 in which recesses 10 are formed.

Between the supports 9 and the bosses 6 an The center portion opening 8 is made through the thickness of the plate. This opening leads to a recess 11 on the under side of each one of the bosses 6. It is connected to the slot 7. The openings 8, recesses 11 and slots 7 are for the use of fastening bolts (not shown). Recesses 11 permit the heads of the bolts to be seated therein and the openings 8 permit the insertion of the fastening bolts from above Without loosening the plate from the tie. It will be noted in Fig. 5 that the camber 5 pressed up from beneath substantially leaves the raised portion of the plate of the same thickness with a hollow 19 on the underside. tant point in my method. The cross section of the plate is preserved so that its strength is not reduced. In the formation of the bosses 6 and Washer supports 9 the extent thatthe material is raised above the upper surface of the plate corresponds to recesses beneath. The metal re moved from theopenings 8 and slots '7 is used to build up the projections 9.

In Figures 7 to 12 inclusive a modified tie plate 13 is exemplified. It simulates the ordinary form of plate which is fastened by well known spikes or otherwisethrough openings 16. The center area is formed thesame as in. Figures 1 to 6 inclusive. On each side of the canted-cambered area rip-standing flanges 14 and. 15 are formed. The base of the rail (not shown) is positioned between these fianges. There are two at one side and one at the other side, respectively at 15 and 14. Beneath the flanges or abutments 15 recesses 17 are formed and beneath the shallower abutments 14 recesses 18 are formed by pressing the metal upward. The difference in height of the

flanges

14 and 15 conforms approximately to the slope of the canted surface 2. This relation is also followed in Figs. 2 and 3 in which the left hand projection 9 is shallower than the one on This is an importures it is obvious that my tie plates can be made of less weight than is usual, thus effecting a large saving in their use.

What I claim is:

1. A tie plate comprising a relatively thin and fiat unitary plate, a raised area on the upper surface inclined in one direction and curved in a direction approximately at right angles to the incline adapted to receive the weight of passing trafiic, a corresponding recess on the under side of the plate, and a reinforcing margin of the unitary plate enclosing the raised area, said plate being provided with rail positioning and fastening means within the reinforcing margin.

1 2 The tie pla-te comprising a relatively thin and flat uniform plate, a raised area on the upper surface canted lengthwise of the plate and cambered crosswise of the plate, a recess of approximately similar shape on the underside of the plate, a reinforcing margin retaining the original thickness of thepla'te which margin entirely encloses the canted and cambered configuration, and rail positioning projections formed on theupper sur face of the plate adjacent the configuration, said projections having a recess beneath the same of approximately the same contour.

3. As an article of manufacture, a fiat plate of approximately uniform cross section with a portion enclosed by a reinforcing margin, said plate having a canted and cambered raised portion on which a railway rail is to be seated the surface not included in the canted and cambered area being raised at isolated points to position the rail and having recesses on the underside of the plate of approximately the same contour as the .configura tion on the top of the plate.

4. As an article of manufacture, a tie plate for the support of a railroad rail, said plate having an approximately uniform thickness throughout, the upper and underside surfaces being an ap proximate duplicate of each other, the upper surface having a raised canted shape in one direction and a raised cambered shape at approximate right angles to the canted surface, without encroaching on a margin of the original plate that extends all around the outer edge of the plate and projections formed on the upper face adapted to position a railroad rail on the formed surfaces.
