ASSIGNORSTO OXWELD RAILROAD SERVICETGOMPANY, A CORPORATION OF WARE Application filed September 28, 1929.

This invention pertains to a device for fastening. a railroad rail to a tie, and more specifically to adouble wood tie. This device comprises a tie plate adapted for being attached to a double wood tie, and a clamping device for attachingthetie plate to the rail..

Thisclamping device is claimed in our coending patent application bearing Serial Number 395,862. 1

.Double wood ties fore butthe. means railroad rails have not been. factory. .For instance, a common means of joining the ties and attaching them, to the rail was to employ a tie plate large enough have been used heretofor attaching them to holding spikes were driven into. the ties. This fastening means was unsatisfactory because the spikes could not be kept tight and consequently the rail pounded the tie plate and wore the tie underneath. Therefore, one object of this invention is bination tie plate to whichthe rail and tie may be firmly secured. I v

. Another disadvantage with tie plates used heretofore is due to the fact that the holding V downward through the tie plates into the tie. Vertical spikes are loosenedby the movement of the rail and also by the expansion of the tie due to the water that runs down the spikes. Furthermore, the water carried intothe tie by the spike holes tendsto rot the tie., Consequently, vertical spikes must be tightened frequently, and. the spikeholes must bev plugged and the spikes redriven at intervals. Therefore, another object of this. invention plate that is attached to a tie by spikes driven horizontally into the side of the tie so poundingof the rail bypassing trains does not loosen them. Another object is to provide a tie plate thatshields the spike holes from rain and other falling water thereby preventing loosened spikes. Another object is to provide a tie plate that may be attached to a tie more easily than those used heretofore. Another object is to provide a tie plate that ,maybe. attached to the ties before they are sent out along the right .of way and, also, so thet-ie plates may be secured to the ties more entirely satisto provide a comis to provide 'a tie' stantially central of I oFFics OF LA GRANGE, AND ISAIAH ALLISON, 0F FOREST PARK, ILLINOIS,

firmly than has been the .practiceheretofore. Still another object is to provide a: combination tie plate tiat may be attached to a railroad rail with suflicient security so the rail will not creep thereby eliminating the need for anti-creepers.

Still other aims, objects, and novel features will be apparent from the following description and the accompanying illustration in which:

drawing comprising a plate a back block 13; a key 14:;and a 11; a clip 12; a wedge cotter 15; constructed, assembled and associated with a rail 16 and a ie 17 in the 01- lowing manner.

A double wood tie is usually composed of duplicate sections 17 which are joined'near each end to form asingle tie to which the rails are fastened. For simplicity, only one end of such a tie will be shown and'described I herein together with our improved means for joining the duplicate portions thereof and for fastening a rail thereto.- It being understood that the means. for joining the sectionsof the tie and for fastening the rail thereto is the same at each endofithe tic.

The plate 10 is formed of a fairly heavy sheet of metal such as iron or steel having the edges 18 thereof turned downward and provided with vertically elongated horizontal openings or spike holes 19. turned edges 18 form the sides of the plate 10 which are spiked to the tie sections 17. Subone end of the plate 10 sides formed by separating the is a tongue 20 I the pl te 10.- lhis t ngue thereof from sides andoutside face,

than thewidth of the 27, so the key will pass bent upward and over to form an abutment or socket for the edge of the rail 16. In the portion of the plate 10 not covered on the upper side by the rail 16 or on the under s de by the tie sections 17 a rectangular opening 21 is provided having the outer edge 22 thereof substantially flush or in vertical alignment with the inner edge of the rail 16 when the outer edge of the rail is seated in the. socket .20. The opening 21 is substantially midway btween the edges of the plate 10 and in longitudinal alignment with the socket or abutment 20. Welded or otherwise secured to the under side of the plate 10 substantially midway between the depending edges 18 is an inverted U-shapedseparator 23 that-holds the tie sections 17 apart. .The'back block 11 has parallel sides and a Width slightly less than that of the opening '21 in plate 10. The top and bottom are at right angles to the si(les, and the back 1s at right angle to the top and bottom, but the face 24 or inside surface is inclined'outward from bottom to top for a purpose that will be described presently. Theback or inside surface of the block 11 has a recess 25 therein adapted to fit overthe inside edge of the opening 21 for the purpose of holding the block in fixed position with relation to the plate 10 when the device is assembled.

The clip 12 is rectangular in shape and about the same width and height as the back block 11. The outside surface of the clip has j a recess 26 therein with the upper wall thereof inclined relative to the lower. The distance between these walls is such thatwhen the clip is forced over the contiguous edges of the base of the rail 16 and the opening 21 .of the plate 10, the inclined walls of the recess 26 will clamp the rail 16 to the plate 10,

The wedge 13 is about as wide as the back block 11 and the clip 12. The top, bottom, are at right angles to each other, but the inside face is inclined outwardly from bottom to top at the sameangle as the outside surface 24: of the back block 11. Also, the wedge 13 is somewhat longer than either the back block or clip, and it has a rectangular"aperture 27 extending therethrough from side to side near the small end thereof. This aperture- 27 is positioned so a portion thereof is above the top of the plate 10 when the device is assemblethand the top of the aperture is inclined with relation to the top'and sides of the wedge so it is at an angle thereto. The key 14 has a thickness slightly less aperture 27, and one of the sides is inclined with relation to the other. The Width of the key at the larger end is less than the length of the aperture therethrough; This feature is not important as the mechanism will perform itsintended function if the key does not pass through the aperture n the 'ient places and then attaching them to the the plates have been {two plates attached thereto have been wedge. Extending from side to side through the small end of the key are a plurality of holes 28 of such size that the cotter 15 may be inserted in one of them to lock the mechanism together in a manner to be described later.

When the combination tie plate described herein is assembled and performing its intended function, the upper or horizontal portion of the plate 10 rests upon the upper side of the two tie sections 17 which are heldlaterally between the separator 23'and the downturned edges 18. Railroad spikes 29 are driven through the spike holes 19 in the downturned edges and into the sides of the tie sections 17 The spike holes 19 are elongated and the spikes 29 are preferably in the lower end of these elongated holes so that any downward does not tend to move the spikes but,'instead, moves independently thereof. By this arrangement the relative movement between the plate 10 and the tie sections 17 caused by passing trains does not tend to loosenthe "spikes 29. Also, the plate 10 shields the tie sections around the spikes from rain or other falling water so that this portion of the tie is kept from getting wet' and expanding or swelling and thereby drawing the spikes. Furthermore, as the tie is kept dry around the spike holes, water ,doesnot enter the tie alongside the spikes and rot it.

The plates 10 may be attached to the ties at the railorad shops, yards, or other convendistributed along the right of way and placed in service by simply rails. It is customary to attach the plates 10 to the ties so that the .rail abutments or sockets 20are on the outside of the rails but, in order to make it more convenient to attach the ties to therails after attached to the ties, the to each tie, may be positioned thereon so that the abutments 20 are between the rails or so that one is inside and the other is outside. I

After the ties with the, plates 10 attached I placed in service by attaching the plates to the railroad rails, each plate is joined to its respective rail in the followmg manner: I

" The outer edge, of the base of the rail 16 is firmly seated in the socket or abutment 20 which is formed so that the inner surface thereof conforms closely to the contour of the rail. The recess 26 of the clip 12 surrounds the inner edge of the rail 16 and the outer edge 22 of the opening 21. Thewalls of this recess 26 are mclined so the bottom conforms to the bottom of the plate 10 and the top conforms to the topeof the rail when the inside wall ofthe clip 12 is substantially vertical or at right angle to the upper surface of the plate 10. s i

The back block 11 is also positioned within the opening 21 so that the inner edge of the opening is in the recess 25 of the back block, and the inclined face thereof is toward the clip 12 a d the rail 16. The recesses in the back block and the clip hold them securely in assembled position and prevent them from moving either up or down with relation to the plate 10.

The wedge 13 is positioned within the opening 21 with the small end thereof upward so that the inclined face of the wedge is in contact with the similarly inclined face of the back block 11, and the vertical face thereof is in contact with the vertical face of the clip 12. The wedge is of such thickness that when in this position enough of the aperture 27 eX- tends above the upper surface of the plate 10 to provide room for the key 14 therein.

The key 14 is within the aperture 27 in such a manner that the inclined face thereof is uppermost and in contact with the similarly inclined upper wall of the aperture 27, and the lower face thereof is in contact with the upper surface of the plate 10 at each side of the opening 21.

During the operation of assembling the component parts of the device into the relative positions just described, the key 14 is driven some distance into the aperture 27 of the wedge 13 thereby forcing the wedge in an upward direction between the back block 11 and the clip 12. The wedge, in turn, forces the clip 12 over the edge of the rail 16 and the plate 10 with sufficient force to clamp the rail to theplate withsufiicient pressure to prevent the rail 16 from creeping or moving relative to the tie plate.

This method of clamping a rail to a tie plate is unique in the fact that a series of three wedges are employed in a combination that is arranged so the first exerts a strong force to move the second, which, in turn, exerts a much stronger force on the third, and theclamping pressure is that exerted against the inclined sides of the third wedge. By this unique arrangement clamping pressure is secured than that usually employed. Therefore, the rail is held to the tie more securely and with sufficient pressure so it does not creep. This eliminates the necessity for anti-creepers which are a source of trouble and only partially effective. a

The major elements of the three wedge combination, referred to above, are: the tapered key 14 which is considered as being the first wedge; the wedge 13 which is considered as being the second and is moved by the first; and the contigous edges of the base of the rail 16 and the outer edge 22 of the opening 21 of the plate 10 are considered as the third upon which the pressure of the second is exerted through the medium of the clip 12. The pressure exerted upon the tapering sides of this third wedge is also the pressure which a much greater clamps the two portions thereof together and, as one of these is a portion of the rail and the other is a portion of the plate, the pressure exerted upon the tapering sides of the third wedge is, therefore, the pressure that clamps the rail to the tie plate and, in turn to the tie to which the tie plate is attached.

It is understood, of course, that this combination tie plate may be modified so that it may be attached to ties of difiierent kinds and shapes, and the size of the component parts thereof may be changed and the arrangement thereof may be varied to meet the needs of varying conditlons wlthout departing from the spirit of the invention or sacrificing anyv of the rights thereunder.
