METALLIC RAILROAD-TIE.

Specification of Letters Patent. Patented Aug. 20, 1912.

To all w/LOm it may concern:

Be it known that we, MARY J. FRANCIS and ALLISON Morrn'r'r, citizens of the United States, residing at Galeton, in the county of State of Pennsylvania, have invented t a new and useful Metallic Railroad-Tie, of which'ithe following is a specification.

The present invention relates to improve ments in metallic railroad ties, the primary object of the invention being the provision of a metallic tie having two parallel upstanding webs longitudinally thereof and provided with rail flange and rail brace -receiving slots at the rail bearing portions thereof, a plate being provided to fit within the slots and below the rail flange and brace to lock the webs against spreading, whereby a rigid and light metallic tie is provided and one which will lock the tie against turning and will permit the desired longitudinal ex ansion thereof.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement .of parts and in the details of construction hereinafter described and claimed, it beingunderstood that changes in the precise embodiment of the invention herein disclosed-can be made withinthe scope of what is claimed without departing from the spirit of the invention. In the drawings-Figure 1 is a perspective view of several of the ties placed in rail supporting position. Fig. .2 is a section through a rail showing the supporting edge of each one of the webs and the adjacent brace portions in elevation. Fig. 13 is a longitudinal sectional view through one end of one tie. Fig. 4 is a top plan View of a portion of the tie showing the means for preventing the creeping of the tie. Fig. 5 is a perspective view of the railflange engaging wedge and brace. Fig. 6 is a perspective view of the plate for preventing the webs of the tie from spreading.

Referring to the drawingsl the numeral 1 designates the base plate of a tie, which is formed of metal and provided with two parallel upstanding webs 2. Cut from the body of the webs 2 of the tie is a prong 3, which provides a means to engage the surface and prevent the longitudinal creeping of the tie due to any cause whatsoever.

The upper edge of the respective webs 2 at the rail supporting .portion of the tie are each provided with a recess 4 so cut as to Application filed April 5, 1912. Serial No. 688,797.

provide an inclined projection and a rectangular projection 6.

In order to hold the webs against spreading, the plate 9 is provided with the two parallel flanges 10, is positioned within the respective slots or recesses 4 so that the flanges 10 thereof project upon the outer faces of the webs 2 and are held thereto by means of the apertures 11 and bolts 12. The plates also provide the proper base for the fitting of the rail flanges rail 8, which as clearly shown in Fig. 2, fits upon the plate 9 so jected below the projection 5 and is locked therein by means of the rail brace and wedge 13, which as shown in Fig. 5, is provided with the recessed portion 14 and the projection 15, so that the said brace may be inserted within the remaining portion of the recess t. By this means the projection 15 and the reduced portion due to the recess 1% receives the projection 6 of its and rail brace relatively to the rail and also support and carrying web. The rail flange engaging lip 16 of the brace 13 is curved as at 17 to fit upon the flange 7' of the rail and thus securely holds the rail in the proper position against spreading or turning, but permitting the necessary longitudinal movement due to the contraction and expansion of the rail. A rectangular aperture is provided through the brace 13 and when the brace is properly positioned, the aperture 18 is upon the opposite side of the web 2 to the projection 15, so that the locking pin 19 may enter the aperture 18 and act as a wedging means or locking means to hold the wedge relative in position against any movement.

The upper edges of the webs 2, may be straight, but in order to reduce the weight and economize metal, they may be curved as shown, both intermediate of their ends an at the ends.

From the foregoing description taken in connection with the drawings, it is evident that a metallic railroad tie made according to the present invention will permit of the easy introduction and removal of the rail, while the wedging and bracing device 13 will lock or wedge the respective flanges of the. rail in the pro-per rail supporting position, the coaction thereof with the respective lugs 5 and 6 of the webs'holding the rail in place against spreading or turnrespective web 2, will limit the movement of the wedge 7 and 7' and the ing. By reason of the plate 9 and the positioning thereof upon the upper recessed ,cdges of the webs, the webs are prevented against spreading at the rail engaging portions thereof and thus form a ri id structure at this point.

What is claimed is:

1. A metallic railroad tie havin longitudinal base plate provided longitudinally disposed and parallel flanges, the rail,

bearing edges of each flange prcvided with a rail flange receiving recess of greater length than the'rail base and one side of which recess is engaged by the rail base a plate of substanti lly the sin is width as the rail base having its ends seated with in a recess of each flange and forming a means to retain the flanges against spreading and a support for the rail base between the flanges, and a removable rail base and flange locking block insertible in each rccess to hold the base downwardly and seated against the opposite side of the recess. I

2. metallic railroad tie, having a longitudinal base plate provided with longitudinally disposed and parallel flanges, the rail bearing edges of each flange being provided with a rail flange receiving recess of greater length than the rail base and one side of which recess is engaged by the rail base,

a plate of substantially the same width as the rail base having its ends seat-ed within a recess of each flange and forming a means to retain the flanges against spreading and a support for the rail base between the flanges, two blocks to each rail base, each of which is provided with a rail base engaging lip and a recessed portion upon the opposite side to the lip for insertion witlr in the recess of its flange when the lip is in rail base engagement, and a'removable locking pin for co-action with the block and flange to lock the block against longitudinal movement.

3. A metallic railroad tie, having a longitudinal. base plate with two parallel upstanding flanges, said flanges at the rail support- I ing edges thereof being provided each with a modified dovetailed recess for the reception of the base of a rail, said recess being of greater width than the rail base, a plate connected to the upper edges of the flanges with its ends seated within the opposite recess to form a tie to hold. the flanges against spreading and to provide a support for the rail base the full width of the tie, a removable rail base engaging block insertible in each recess and having a lip to engage one- MARY JANE FRANCIS. ALLISON MOFFETT.
