April 8, 1930. .1. J. Ross REENFRCED MINE TIE Pild April 2:5. l1929 l l I Il Patented Apr. 8, 1930 UNITED STATES JUSTUS J. ROSS, OF HUNTINGTON, WEST VIRGINIA REENFORCED Minn TIE Application filed April 23,

This invention relates to mine ties and has special reference to means for reenforcing such tiles at the points where necessary, namely, where the rails rest on the ties and where the rail fastening clips are mounted.

Mine ties are sold almost entirely by weight and it is obvious that if. the weight of the ties can be materially reduced without sacriicing their strength a great saving in the. cost of laying tracks in mines will follow. It is therefore an object of the present invention to provide a tie which may be formed of very light metal and reenforce the same where it supports the rails and where the locking clips are mounted.

A further object of the invention Vresides in the provision of a reenforcing means placed at the pointv where the pivoted rail clips are riveted to the tie; thus eliminating undue wear on the tie by corrosion and rotation of the clips which would tend to loosen the clips with the consequent dangerof freeing the base of the rail and permitting it to turn over.

Other objects and advantages of the invention will be apparent from the following description when taken in connection with the accompanying drawing, in which Figure l is a side elevation of one form of mine tie embodying the present invention.

Figure 2 is a sectional view taken on line 2-2 of Figure 1,.showing one of the clips turned to inoperation position.

Figure 3 is a fragmentary, longitudinal section through a modifiedk form of construction.

Figure 4 is a. plan view of the structure shown in Figure 3.

Figure 5 is a transverse section through a slightly modified construction of tie; and

Figure 6 is a transverse section through a further modified form of tie.

Referring to the drawings in greater detail and especially to Figures l and 2 the nul? meral 1 designates a piece of metal tubing cut to the proper length and provided with flattened or collapsed ends 2; although if found desirable the tube may be flattened throughout its length. Mounted adjacent the ends of the tube on the flattened portion 1929.' `serial Nopaeaiso.

thereofand preferably on theV top side are reen'forcing plates 3. These plates reenforce thetie at the points where the rails are supported, which, as a/matter offactare the only. points where strength is required; itbeing neadily apparent thattheportion of thevtie intermediate the rails has as its sole function to maintain the proper gauge between the` rails.

The plates are securedl to the tieproper by vmeans of rivets@L and these rivetsalso serve asv aV meansv for pivotingV the. rail; clips 5E. This feature Aof mounting the rail-clips;

on clampsV on a. reenforcing. plate is kalso .of

considerable importance Afor the reason. that where pivoted cli-ps are used iny conjunction: with light metal ties,1the.latten are soon rendereduseless dueto the` fact that the clipsrapidly wear through the ties. LThiswearing afway of theV ties bythe clips is especiall'yem-r phasiz'ed inthe case of mine tiesbecause ofV theaccumulat-ion of rust between the: tie andi clip'due -to dampness of the` atmosphere andthe like. y l v g Y o Y lnztheaconstrllctgionshown in Figures and 4f L employv a conventional' type ofv light weight tie as indicatedby thenumelal 10,. and: on thetopof this tieiatithe points wher-e thera-ilsll-.are supported reenforcing plates 12Sare mounted. These platesfarepreferably riveted to the tie' and. certain ofthe rivets serve. aspivots forthe raill securing. clips 1 3.`

as indicated by numeral 1.4. In this form of the inventionfas well asthatv previouslyy described it will be apparent that lprovide, in a light .weight and therefore relatively lowpriced tie,.al l ofthe advantages ofthe heavier ties in thatthe tieis properly reenforc'ed at' the` points receiving the weightjof the cars,

and inY that'this reenforcement. also serves to i;

prevent destruction. of the tie: b v. reason off the action of the railsecuring clips.` in. the modified- Construction shown in Figure einploya tie l2,0 provided with.downturned sido walls. 21' and horizontal flanges 22. With this construction ofl tie the reen forcing plate takes` the form indicated in the Crossfsectional view; i. e., the plate 2B is mountedl on thetop of the'tieat the rail supporting position and is provided with flangesy 24 Which overlap and reenforce the side walls 2l of the tie. As in the previously described forms, the plates 23 are secured to the tie by means of the rivets 25 which form the pivots for the clips 5. Obviously, in this embodiment of the invention the advantages of a light weight tie of the particular design shown are secured Without the inherent defects, namely, fiattening out of the side walls y of the tie by excessive Weight and wearing away of the tie by the rail clips. Y

A further modification of the invention is shown in Figure 6, wherein the reenforcing plate 30 is attached to the under side of ya tie 31 which is of the same construction as that' shown in Figure 4. In this form of the invention the side walls 32 of the tie are reenforced by means of the flanges 33 of the `late 30 and b reason of the reenforcinfr f plate being o-n the underside of the tie it is possible to provideintegral alignment lugs K Se by striking out sections of the metal of the reenforcing plate.

From the foregoing description it will be apparentthat I have devised a novel form of mine tie, several modifications of which are shown in the accompanying drawings; that Y theV tiemay be made of very light metal and yet be strong and durable in operation; that reenforcement of the tie is so arranged as to` not only-strengthen the tie at the point of railsupport but also to cooperatewith the pivoted clips so as to prevent undue Wear on the tie by reason of corrosion until the clips'become loose and the rail freed from its anchoring means; and that in brief, I provide a tie of light weight and relatively low cost which provides the service and durability of heavier and more expensive ties.'

In accordance with the patent statutes I have described what I now believe to be the bestembodiment of the invention, but I do not wish to be understood thereby as limiting myself or the scope of the invention, as many changes and modifications may be made Without departing from the spirit of the invention; all such I aim to include in the scope of the appended claims.

What I claim as new and desire to secure by Letters Patent is l. A mine tie formed of light metal, reenforcing plates applied to the upper surface of the tie so as to aid in supporting the railsk to be mounted thereon, clips for securing the rails to the tie, and means for securing the plates to the tie and for pivotally mounting the clips on the plates.

2. A mine tie formed of metal tubing, portions of said tubing being collapsed, and reenforcing plates secured to the collapsed portions of the tubing.

3. A mine tie formed of metal tubing, portions'of said tubing adjacent the ends thereof being collapsed for the purpose described.
