RAILWAY METALLIC 'IIE.

Specification of lietters Patent.

Patented Oct. 28, 1913.

Application" filed December7, 1911. Serial No. 664,428.

To all whom it concern Be it known that I, JOSEPH A. Mo- CRAGKEN, a citizen of the UnitedStates, re siding atAltoon'a, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Railway Metallic Ties, of which the following is a specification.

This invention relates to metallic railway ties of the built up type, and has for itsprimary purpose improved means for shifting the rails, when through use the side of the rail head becomes worn to such aneXt-ent that the track is no longer in gage.

Another object of this invention is to pro-- vide a tie, of the built up type, that readily adheres to the roadbed, without the usual difiiculty of center binding or weakening under the stress caused by heavy cars pass ing over the same.

Another object of this invention is to provide an improved means for holding the rail to the tie, as well as to shift the rail when necessary, together with means for obviating center binding, and at thesame time grip the ballast such that both longitudinal and With these and many other objects in view,

as will be more readily apparent, as the nature of the invention is better understood, the same consists of the novel combination, construction and arrangement of parts as will be hereinafter more fully pointed out, illustrated and claimed.

The essential features involved in carrying out this invention are necessarily susceptible to a wide range of structural modification without departing from the spirit or scope of the invention, but a preferred and practical embodiment of the same is illustrated in the accompanying drawings, in which:

Figure 1, is a view in perspective, showing my improved built-up metallic railway tie, and particularly illustrating the method of holding the rails as well as the means for shifting the same. Fig. 2, is a view in perspective of a modified form of my improved built-up metallic railway tie, showing particularly the means for gripping the ballast to prevent transverse movement of the tie on the roadbed, as well as clearly showing the method that I employ to obviate center binding.

Like reference numerals designate corresponding parts throughout the figures of the drawings.

The present invention coiitemplates a metallic railway tie of the built-up type, and primarily consists of a main portiondesignated by the numeral 10, having bot-tom :flai'igcs 11, which serve the purpose of interlooking with the ballast, thus materially assistingin obviatingmovement whenvin use on the l 'oadbed. The body 10 is further provided with oblong openings 12, intowhich the key 13 is driven, thus drawing the two end sections together this action being made possible by the peculiar construction of the tie, whereby the built up end arrangement designated in itsentiret-y by the numeral 14,

ismade integral, threugh the use of rivets or otherwise, with one of the body sections 10 of thetie, while the built-up arrangement, designated as a whole by the nuincral 15, is likewise attached-to the opposite'body section. This construction provides in a very practical way shiftingthc rails, which are attached to the top 16 of the tie.

The end sections of this improved railway tie. primarily consist of two flanged channelshaped sections 17, turned back to back, having sandwiched therebetween, the plates 18, WllTCh'lll addition to serving the purpose as spacing blocks, are continued above the top face 16, and provided with rail engaging notches 19, which engage the flange 20 of the rail.

Another important feature of this construction also noticeable in Fig. 1 of the drawings, is that the body section 10, upon which the end arrangement is made integral therewith, is also continued above the top face 16 of the tie as shown at 21, and 006perates with the sandwiched section 18, to hold the rail to the tie. The inside flange 22 of the rail is preferably held to the tie through the medium of clamp 23, which is held in position by the clamp bolt 24, as clearly illustrated in Fig. 1 of the drawings.

The end sections 14 and 15, in addition to being formed of channel section 17, are further provided with U shaped flanged ballast engaging elements, designated by the numeral 25, and primarily consists of a flanged base portion 26, ballast abutting ends 27, and a top portion 28, forming the top 16 of the tie. The combined ballast gripping and abutting member 25, is preferably held to the body of the tie through the medium of rivets, or if preferred the same can be welded to the tie.

A slightly modified form of tie is shown in Fig. 2 of the drawings, in which the ballast abutting portion 27 is turned upward and inward and preferably secured to the body 29 of the tie through the medium of rivets 30. This construction of tie shows the central web portion 31 cut away, allowing the tie to readily adjust itself to the roadbed. In this construction of tie, I prefer to form the same of two channel sections 32, turned back to back, with the central portion 33 cut away. Upon the top is preferably placed a rectangular binding piece 34, which forms the rail seat-s 35.

The channel sections are clamped, or secured together through the bottom flanged element 36, having flanges 37, and provided with upwardly and inwardly turned ballast abutting elements 38. This construction, in addition to forming a tie that is not susceptible to movement on the roadbed, has a resisting moment beneath the rail load sufficient to carry the load without deflection or creeping.

WVithout further description or elaboration, it is thought that the many advantages of my improved metallic railway tie are readily apparent, and what I desire to secure by Letters Patent is 1. A metallic railway tie comprising a body including rail-supporting end portions having channel members arranged back-to-back, a longitudinal central vertically disposed stifiening member rigidly united with said channel members of the end portions, and rail securing means carried by said end portion.

In a metallic railway tie, the combination of flanged body portions, terminating in and with the built-up end portions of the tie, keys cooperating with key-ways in the body portion for the purpose of shifting the end portions of the tie, channeled sections, turned back to back, flanged base portions having the body portion turned upward and outward, forming the base ballast gripping portion, the ballast abutting portion, and the top or rail seat portion.

3. In combination, the elements forming a metallic railway tie, channeled side sections, a combined top rail seat and channel binding plate, flanged base portions binding the channel sections, gripping the ballast and having upwardly and inwardly turned ballast abutting portions, the body portions having the bottom flanges cut away, together with a portion of the center web, substan tially as described, illustrated and claimed.

In testimony whereof I afliX my signature in presence of two witnesses.
