TIE PLATE.

Application filed June 1, 1925.

To all til/m it may concern:

Be it known that we, JULIUS Knows- SCI-INl'lT and EDWIN H. BELL, citizens of the United States, residing, respectively, in the town of'NeW Canaan, of the county of Faii'field, State of Connecticut, and in the city of Chicago, county of Cook, State of Illinois, have invented certain new and use ful Improvements in 'lie Plates, of which the following is a specification, reference being had to the accompanying drawings, and to the reference characters marked thereon, which ilorm a part of this specification.

This invention relates to tie plates, more particular.

and '0 plates of channel form, i. e. having tieei acing side flanges.

Many plates 51 ble as to form, section or weight to one l tion in track will not give satisfactory service in another location where dilierent conditions exist. In sandy country, for example, ertrcine atmospheric conditions afi'ect the tie and shorten its life, The tie is aliected with a species of dry rot, the fibres separate, it splits longitudinally, and disintegration occurs. In such situations, the spikes loosen and tail to hold the plate to the tie, and the gauge of the rails cannot be maintained, requiring constant regrauging and replacements.

This destructive atmospheric action upon the tics is' grcatlyincreased when the tie plates used are of a section and weight desirable for use in track in mountainous country having sharp curves and high grades. The wave motion of the rails produces a hammering action of the plate on the tieand the heavier the plate, the greater the blow.

it is the primary object or" the present invention to produce a tie plate adapted for all atn'iospheric and topographical conditions in track and especially to meet and overcome the ditiicultics above mentioned.

To the accomplishment of these and other objects, our invention consists in the devices and combinations of devices herein illustrated, described and more particularly pointed out in the appended claims.

In said drawings, in Figures 1 to 6, in-

elusive, our preferred form of tie plate is shown, positioned upon a tie B, ready to be but not actually seated or imbedded thereon. The plate A, is provided upon its top surface with a transverse rib or rail abutting shoulder 1, preferably extending higher at its two ends 3, 3. The rail bearing surface of the plate is canted, that is to say, it inclines from the base of the shoulder 1 above the plate at its central portion 2 than towards but not entirely to the inner end 5 of theplate, the inclination beingindicated by the line a. The rail bearing surface is, also convexly rounded or curved from one side margin to the othen-tq-nroduce a crowned or cambered top, asindicated by the convex line he n ntberedrail boa-r its plate, i. e. in the direction of the tie l3, and

transverse to the direction of the rail.

' The bottom of the plate is thus of general channel form, the two parallel side flanges 7, 7, being spaced apart sufliciently to embrace or lie over the upper portion of the side surfaces of the tie B.

The tie bearing surface of the bottom of the plate, intermediate the flanges 7 may be of various configurations. As shown in Figs. 1 to G, inclusive, the bottom is provided with a median,'undulated section, indicated as a whole by the letter C, and extending from the outer to the inner end of the plate. This section C is formed by a plurality of parallel, arcuate undulations, grooves or depressions 8, the long dimension of each groove being transversely of the plate and at right angles to the longitudinal side flange 7. These arcuate surfaces 8 intersect to form a plurality of parallel, short, intermediate ribs 9 which also extend transversely of the plate. These undulations 8 and ribs 9, in this form of plate, do not extend to the flanges 7 at the sides of the plate, thereby forming, interme diate their ends and said side flanges 7, relatively narrow, flat, tie bearing surfaces 10, 10, which extend longitudinally of the plate and arallel to the flanges 7 Spike holes ll may be placed, as shown, or otherwise, as desired. The flanges 7 are preferably somewhat tapered, the inner surfaces 12 inclining slightly outwardly and downwardly, thereby cooperating with the other features of the bottom to compress the fibres of the tie and hold the plate A more firmly to the tie B.

The plate A is initially positioned upon the tie as shown in Figures 1 to 6, inclusive. When pressure is brought upon it by the passing of train loads over it, or otherwise, the relatively narrow surfaces 10, 10, will bear into and make seats below the normal top surface of the tie. The ribs 9 will also enter the tie lengthwise of the grain of the wood, spreading the fibres apart. lVhen the plate is firmly seated, it will be found that the fibres of the tie have been compressed and that the originally flat surface of the tie has become changed into a configuration complemental to the under surface of the bottom of the plate. It will also be found, after a comparatively short period of use in track, that this. complemcntal tic surface has become considerably hardened and the tie compacted, so to speak, wherebfliihe tendency to disintegrate is reduced an g-iaite life of the tie prolonged. t

The normal function of a camber or crown on the-rail bearing surface to counteract the tendency of plates to move or shift and to cause rattle due to the wave motion of the rails, is raised to a maximum, when the plate is provided with the downwardly projecting, tie embracing side flanges 7, 7, the crown and the flanges thus cooperating with each other and with the spikes to hold the plate A firmly upon the tie B.

By making the rail abutting rib 1 of unequal height, we are enabled to save metal, which is a consideration when plates are sold by weight, and at the same time retain a high shoulder across the median longitudinal line of the camb'ered rail bearing surface of sufficient strength and size to withstand the side thrusts and strains 'rom passing trains, while the parts 3, 3 of the shoulder are sufficiently high and strong for this purpose. The rib 1, though of unequal heights, is of such-length as to cooperate with the side flanges 7 to prevent the tendency of the plate A to twist or shift angularly on the tie B.

In the plate above described, the tie hearing surfaces 10 and the points of the ribs 9 are in the same horizontal plane, as will be seen by reference to Fig. 4.

In the modification shown in Figure 7, the bottom, as awhole, is concavcd or curved substantially parallel to the curvature of the crowned top. The body of the plate, therefore, will be of even cross-sectional area throughout its width, instead of being thicker at the center than at its sides, as is the plate illustrated in Figs. 1 to 6/ In all other respects, the plate shown in Figure 7 corresponds with the plate shown in Figs. 1 to6.

The bottom of the plate intermediate the flanges 7, 7, may be of various configurations, and in the -.modification shown in Figure 8, the grooves 8 are omitted and the tiebearing surface 13 is continuous. Itis shown as concavely curved corresponding with the convex curvature of the crowned top and of even thickness, as is the modification shown in Fig. 7. In all respects other than by the omission of the grooves 8, it corresponds to the plate shown in Figure 7.

In the modification illustrated in Figures 9 and 10, the plate is in all respects like that first described with the exception that the grooves or recesses 8 and their dividing ribs 9 extend from one side flange 7 to the other side flange 7, thereby omitting the flat tie bearing surfaces 1O, 10.

In the modification shown in Figures ll and 12,'the plate is in all respects like the plate shown in Figures 1 to 6, inc., with the exception that the grooves or recesses 8 and their intervening ribs 9, while parallel to each other, extend lengthwise of the plate at a different angle to the side margins of the surfaces 10; that is, diagonally instead of at right angles thereto.

In the modified form shown in Figures 13, 14 and 15, the space between the inner faces of the side flanges 7 is provided with a pair 'of flat surfaces 14, 14, one at each tnd of the plate, and with an intermediate recessed or grooved section C. The grooves 15 and intervening ribs 16 (corresponding with grooves 8 and ribs 9 before described) 'while parallel to each other, are also parallel to the sidev flanges 7.

In all of the plates, it will be' 'seen that considerable metal may be saved, to lighten the weight, by tapering the top surface downwardly from behind the shoulder rib 1 towards the outer end of the plate, as shown at 17, and similarly, tapering the other surface, from where the cant and camber leave on, downwardly toward theinner end 5 of the plate, as shown at 18.

The plate in all of the forms shown, and in other modifications which will be obvious to railway engineers familiar with track construction and conditions, is strong, durable and adapted to meet all the various requirements of road conditions.
