RAILROAD-TIE.

Specification of Letters Patent.

Patented June 10,1913.

Application 4filed J'uly 20, 1912. Serial No. 710,713.

T 0 all whom 'it may concern:

Be. it known that We, EDWARD S. Prim-:Nv and l'niLnMoN Plenum', citizens ott the United States, and reSidentS oit' (flhieago. in the county ot Cool: and State' of illinois, have invented certain new and uset'nl 'lun provements in Railroad-Ties, of which the followingr is a full, clear, and exact specitication.

This invention relates to improvements in railroad ties bent from sheet metal, and be* t'ore 'use filled with eeinent, concrete or other suitable filler, renderingr them solid throughout, and in which the. tilting contracts and on drying' shrinltfs away from the metal Walls of the tie. l

The object ot this invention is a filled sheet metal railroad tie, the set and dried filling of which is closely1 and tightly em- Ybraced by they surrounding walls ot metal, and means hy `which the filling mayy he :so

embraced whether the shrinking he great or I small tliroue'hont, or at intervals oft; the

length of the tie. y"

A further object ot: this invention is to distri-2nd the metal oit' the tie at'ljiaeent its opposing longitudinal edges without changingthe linen oit other portions ot' the tic, and in auch a manner that the distended portion locks the filling against endwise movement in the tie. 1

it Stili 'further olrieet ot' this invention is to provide a tie with end closing caps for its filling, which cap` are ot simple eonstruction, and conveniently locked to the tie againet accidental detaehnieut.

ltVith these ends in View, our invention finds embodiment in certain features ot' noveltr in the construction. eomhination and :nrangenuuit ot pa rts hy which the Said olo- `jects and certain other objects are hereiie ait'ter attaiueifl, all as: fully described with retereucr.: to the accompauvmn d ra wing, and more particularly pointed out` inthe claims.

ln said drawiiur: Figure il illustrates ak bottoni plan view olE a railroad tie in which this invention finds euihmlinunt. ltiir. 2 illustrates a. transverse Section on the line of Fin'. il, with the tie bottom side up. Fig'. 3 is u bottom plan view illustrating' a moditied form of this invention. hier. t is Fig. 5 illustrate,l a de tail perspective ot' a tie provided with means tor Securing thereto an end closing' cap. and l `iff t3 `is a fare View* of Such a cap, Fin'. 7,

is a elosed section ot a tic provided with a T-t`a5teninn clip, and Fig. 8 is a perspective ol Athe T-elip detached.

Similar characters of reference indicate the salue parts in the several figures o'l the drawing.

7 indicntes a railroad tie composed ot" sheet metal 8, lient to the form shown, hut may he of amr other suitable form, and filled with cement., concrete or other suitable inaterial J adapted for the purpose, and which on dryingr contracts and shrinks away at one or more places. or in its entirety, from the Sheet metal walls of the tie, but form:y a solid, and when dried, a hard mass there in. For the convenient introduction and uniform packing of the filling in these tics, and may be a savingr in metal, there is usually an opening l() between' the opposing longitudinal edges 1l-ll of Sheet metal ties, hut so tar as advised no means have heretofore heen provided tor contractingP the metal ot' the tie to close the metal against the filling' after it has shrunk, or to expand the tie to a form looking the filling against' endwine movement' therein. i

A5 he'tore suggested, r-onirete and other filling` containing' moisture on their introduction to the tie, however tightly packed iu the tie, shrink from the Surface of the metal on drying, and unie: somenieans in provided :formingr and holding the metal against. this mass the concrete, soon heroiney disintegrated from jars,` und shoelis from handling', and when in use, and which by this invention is prevented b v perforation 1:2 adjacent the edges of the tie through which to pass 'lip plates lil subsequently having' their ends l-t heut over upon the metal in elip form at the proper time after Vforcing' the metal tie to close contact with the shrunken mans ot t'iling. Afn other words in carrying' out this invention the clip plates lil in straightened out condition are passed through the slots with their enda projet-ting,r from the tie, and this either he 'foro o after the filling is inserted. and then after the fillingr has dried and mrrespond inglv I*ln-nutten the. metal ot the tie is forced to close contar( with the filling', and so held until the clips have heen heut over to a Dosition locking' the Awheel metal t'rom Spread ing. and while three. rau-h rlips are shown at unit'orm intervals of the length ot the tie, n greater or leas number may be employed as Cit memes nel edges seperated from each other, lthe edges of one side or :Ence ol'r which tie exlend in parallel lines, und the other in re- 'versely-curved lines, and means locking und maintaining the opposing curved side edges thereof from expanding.

5. A railroad tie constructed from bent flexible sheet metal having on one face separated opposing longitudiiinl edges, e con'- traetible filler therein, and ineens in the fece oit the tie adjacent seid edges for forcing the Walls ol. the tie against and locking them in contact with the filler, following the contraction thereof from seid Wells.

(3. A eilroad tie coniposeiil of bent conti'netible sheet motel having separated opposinglongitudinal. edges in combination with caps, for closing the ends thereof, end means whereby seid cups are locked to the metal of the tie When Ethe letter is contracted.

7. A railroad tie oil sheet ,metal bent to form, with its longitudinal edges seperated from each other, end contractible, seid tie being provided with perforzttions adjacent its ends in combination with caps provided with lugs for projecting into said perforations, whereby when the tie is contracted :mid caps are locked thereto in a position substmitinlly closing the ends of the tie.

8. A railroad' tie of sheet metal, bent to form, .in combination with u T-'clip locking its opposing longitudinal edges with the stem of said T-clip, projecting substantially below the bottom face of the tie.

9. A railroad tie of sheet metal bent to form, the longitudinal edges of which hare' seperated from each other, in combination with a clip of T iform, the flanges of which connect and lock the opposing edges of the 4o tie with the stein of theT extending in a line parallel with the sides of the tie, substentinllyns described.

In witness whereof, we have hereuntoset our hands and affixed our seals this 16th day of July A. D. 1912*.
