Jan. 26, 1932. v. l.; KEECH RAILROAD TI E Filed July 15, 1951 www M Patented Jan. 26, 1932 UNITED STATES VERNON I.. xenon, or DUALUTH, ninnnsora Y RAILROADTIE t Appncatipn ined July 13,

l i This invention relates to railroad ties, the

principal object beingto provide a metal tie having the characteristics of a firm and positive support for the rails of a track, together with the requisite resiliency of such a suport. i i p Another object is to provide a tie and rail ,fastener therefore whereby as nearly as pos-` sible permanent attachment of therail upon `the tie is accomplishedbyultimate holding adjustment of the fastener. f

metal tie having means associated therewith to insure same against longitudinal movement or slipping as for `example around a curve inthe track or the like.

Still other objects and' advantages of the invention will appear "in the followinglde-i scription thereof.` y y Referring now tothe accompanying `drawings, forming part of this appllcatlon, and

1 wherein like reference characters indicate Figure 2is a plant view of the reverse or bottomof the tie;

`like parts 4 1 Figure lis a top plan View of one of the `improved ties;

Figure V is an enlarged fragmental sectional view longitudinally the center ofthe tie at the `point of rail mounting; and t Figure Il is avertical section transverse the tie as taken on the line 44, Figure 3;

TheV tie and fastener herev illustrated are i identical with those shown in mycopending application upon an improved rail and tie fastener, filed concurrently herewith.

The tie is `of sheet metal, and generally V* shaped in crossgsection, the upper flat surface of which is illustrated at 1 and the inclined `sides at 2. The lower edges of the side portions are spaced apart throughout the lfull length of the tie, and directly beneath each rail engaging area of thetie these side walls are bulged outwardly in angular from asV at 3, the apex of whichangular bulge portion is vertical or at right angles to the flattop `1, so that a transverse section through the i i center of suchbulgedsides would illustrate l a rectangularly shaped tiehaving no bottom w whatever." These bulged portions are to protermediate bulged portion maybe formed in' thesidewalls of the tie as illustrated-in dotted v lines, `Figure 2, at 4; thismodilication being considered no departure from the invention. As a preferred rail fastening attachment I `have illustrated the tie as having spaced rectangularly shaped holes 5, centrally of the, 6 0` tie, and oneupon either side of the rail tread `A further object is to produce a resilientV portion thereof. Within the outermost edge o'f each hole, `farthest from the rail tread portion, is formed an upwardly arched tongue 6 for cooperative engagement with the fastening or holding dog 7 to be installed i one Within each hole and ultimately brought into holding position as by swaging or pound- `ing into place with a hammer or sledge. The dog V7 is provided with a head and tail por*- tion, the head having a suitable mouth for graspingengagementwith the edge of the base 13 of the rail, and the top portion 1 of the tie.` The lips of the mouth portion are indicated at 8 and 9 and the tail at 10, so that `after the rail is in position the dog may be slipped into one of the holes 5 head first, its tail forced downwardly upon the upwardly y arched free extremities of the tongue 6 sufficient to level the latter to its normal posil 8dl `tion wh'en the corners of the tail will over lap the opposite corners of the hole 5 left as by the tongue 6 being narrower than the hole ;s these corners being clearly illustrated at 11 in the two plan` views of the tie aswell asin Figure 3.

Onel materially novel feature is the resilience or yieldability thereof in that the tie is made of a proper thickness of sheet material` y from which it is stamped to permit of breath- 90 ing motion of the inclined sides thereof when a car wheel passes over same; this resulting of ,course from the free spacededges of the inclined sides.

Having thus described my invention, what 95` I claim and desire to secure by Letters Patent, is: t i y Y Y 1. railroad tie made of a single piece of sheet metal, triangular in cross section with a Y the apexof` one angle being open, andlater-` 3f?? ally projecting means spaced longitudinally of the tie to prevent longitudinal movement thereof.

2. As a new article of manufacture, a rail- 5 road tie made of sheet metal, substantially triangular in cross section throughout except at spaced intervals where it is substantially square in .cross section.

3. As a new article of manufacture, a rail road tie made of sheet metal, substantially triangular in cross sectionftliroughout except at spaced intervals where it is substantially l square in cross section, the lower apex yand ends being open.

4. A stamped sheet metal railroad tie characterized by having inclined sides Vand open bottom to afford yieldability to the tic, and bulged portions in the sides thereof to prevent longitudinal movement.

VERNON L. KEECH.
