Application filed March 12, 1923.

T 0 all whom it may concern:

Be it known that I, SAMUEL COFFMAN SAMUELs, a. citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in RailroadeTrack Constructions, of which the following is a specification.

My present invention relates to improvements in track constructions, which will be best understood from the following descrip tion and the annexed drawing of an illustrative embodiment, in which Fig. 1 is a vertical longitudinal section on the line 11 of Fig. 2 of a portion of a railroad tie, showing an illustrative form of my invention applied thereto. Fig. 2 is a plan view of Fig. 1, and Fig. 3 is a section on the line 3-3 of Fig. 2

Like parts have like reference numbers in h se re-1 ie In the form of my invention which I have chosen for purposes of illustration, the tie is t r-me O an upp r p r 10 and a lower portion 11 with the grain extending lengthwise of the tie and with the joint between the two sections also extending lengthwise of the tieand horizontal.

On the top of the tie is a rail plate 12 extending beyond the vertical edges of the tie and having integral portions 131$ ext n ing o n ard, P l l to t e S of the tie. On the bottom of the tie is a suppor ng p a a ac d to he iey bo t 15, which extend through the two plates and through holes extending down the sides of h e Th plate l2 ma he fo med w th dg 16 t oc te th m l 3, n th bolts m y e u e to clamp the rai to the Plate 2 en lth t e y mean .o mm er en a t e ads of h o s 1.5, he x n ed p of h membe 1 White:- ing over the flange of the rail as shown best inFig. 1. The member 18 may be provided wi dowel p s 191 0 p e e t mem ers 18 from turning.

The integral portions 13 are connected to the supporting plate 1.4: so as to prevent motion away from the vertical sides ,of the tie, and preferably this connection will also be me so hat he Plat 1.2 and ay be moved relatively vertically, and as a mean to his end, .I av p v d d h i al mem rs 3 wi h a p ura i y .of mois Serial Ne. 624,350.

tions 20 on the lower end of each of the integral portions 13, which projections extend through corresponding openings in the plate 14, all of the projections 20 being of sulficient length to permit the

plates

12 and 14 to approach each other before the solid portion of the integral portions 13 cont act with h Pla e 4:.- i

In order to transmit the weight and force applied to the rail R by the moving trains tothe plate 14:, I insert between the sides of the tie and theintegral portions 13 blo cks 21 of wood, with the grain thereof vertical, these blocks being of sufiicient length so that the weight on the plate 12 will be trans mitted through the blocks 21 to the supporting plate 14. It will be understood that the plate 14L will rest on the ballast of the roadbed so that any weight transmitted through the blecks 21 Will not be applied to the tie Pr per a the fw ha the tie Pr p will be relieved of a corresponding amount of pressure which would otherwise tend to crush it. The plate may be provided it Pro ecti ns 2 f It will be noted that the integral portions 13, by their connections to the top and boton plates 2 a d y their a with-the sides of the blocks 21 will bind the tie laterally to prevent its being crushed and forced out laterally. Preferably, when the-tie up of the two pieces. 10 and 11, I will apply to the tie additional members to prevent the crushing of the tie, and to end I may provide a plate 23 having .dc w' rd 'p ittt ns an me a P tions 24 in'contact with the sides of the tie, th intt a membe :1 xtend n r u hQles. in a bottom l e v th i h ustre v farm co stit e a portion o e upp r n Pla .4, h h it Will b un too th t; a epa a P at m h Pr ide forth is purpose. bolt extends through Th ie a ou h pla e 23 d th .e f rei d h bo tom p e- When the rail B is on a curve it will be subjected to horizontal pressure, as is well man, a .1 Pr v de a m an for h ldin the rail anchored to resist this horizontal pressure and to prevent overturning of the rail. To this end provide member 27 having, in the illustrative embodiment, an i e 'thp r t .2 en a d in a h e i h ra l Pla 1. we in 1 the te me to fit the side of the rail R, a boss 29 on either side of the member 27 being provided to give additional area. The end of the member 27 away from the rail engages, in the illustrative form, the bolt 26, the member 27 being provided with a slot 30 adapted to permit the extended end 31 of the member 27 to swing into position beneath the nut on the bolt 26. A locking member 32 may be provided, this member having a hole through which the bolt 26 extends, and having a downwardly projecting portion 33 which extends over the edge of the extended portion 31 of the member 27. In addition, I may provide a recess 331 through which a spike or the like may be driven into the tie to hold the member 27 in position.

In present practice, and as is well known, the constant blows of the moving train will cause a crushing or wear in the tie beneath the track plate 12, and when this wear has proceeded sufficiently far, the tie is withdrawn and a new tie substituted for it, although a very considerable portion of the discarded tie is not damaged. By my invention two of these discarded ties may be sawn longitudinally and the undamaged portions of the discarded ties be put together to form the portions 10 and 11, thereby saving one tie and by using the arrangement which I have described, these two p01"- tions may be held together to function as effectively as the original solid tie. The metal members which surround the tie and carry the weight on the rail R will so distribute the load that the two-piece tie will have sufficient strength and moreover will be protected against the crushing blows delivered to the rail R. It will be-understood, however, that my arrangement may be applied to a solid tie. a

It will also be understood that the arrangement which I have illustrated is merely one form of my invention and that the embodiment thereof may be widely varied. 7 It will also be understood that some parts of my invention may be used without other parts. y g

By using the relatively thin blocks 21 at either side of the tie, all or a greatportion of the weight and the force of the blows on the rail R will be transmitted lengthwise of the grain of the wood, instead of crosswise thereof, as inthe usual tie. As is well known, wood has a much greater resistance to crushing when the force is applied-endwise of the grain than when applled crosswise, so that, with my construction, there is little tendency for the wood to be crushed or for the plate to be worn into the side of the tie.

By fitting the end of the member 27 beneath the head of the rail as well as against the side, the side thrust in the rail which would tend to upset it, is more completely resisted, such upsetting motion being transmitted directly to the plate 12 and furthermore being resisted by the other end of the member 27 through its connection to the tie.

By providing the form of connection between the

plates

12 and 14, which I have described, it will be understood that the plate 12 may sink into the tie without interfering' with the operation of the

integral portions

13 and 24 to sustain the sides of the tie, the bolts 15 and 26 being tightened up as required, and the

projections

20 and 25 sliding through the corresponding openings in the plate 14 to permit this adjustment.

The member 27 may be connected to the rail plate 12 in any of anumber of ways and, if desired, may be made integral therewith.
