RAILROAD-TIE.

Specification of Letters Patent.

Patented Oct. 27, 1914.

Application filed May 5, 1914.. Serial No. 836,389.

To all whom it may concern Be it known that I, OLIVER P. MEGAI-IAN, a citizen of the United States, residing at VVesterville, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Railroad-Ties, of which the following is a specification.

My invention relates to railroad ties, my more particular purpose being to produce a railroad tie made of metal and provided with backwardly-turned ends, and to provide a pillow for supporting said back wardly-turned ends, in such manner as to brace the same effectively, and at the same time allow them a proper degree of resilience.

More particularly stated, I employ a? metallic tie made of angle iron and having its ends bent backwardlv and toward each other, and mount upon the body portion of the tie one or more stout springs for engaging the flange ofthe reverting ends of the tie, and thus supporting said flange, while allowing the ends of the tie to spring downward slightly in consequence of pressure upon the rails, which are supported by the ends of the tie. I further seek to strengthen the tie, and to prevent its creeping in the general direction of its length.

Reference is made to the accompanying drawings forming a part of this specification, and in which like letters indicate like parts.

Figure 1 is a cross section through a pair.

of rails resting upon my improved tiethis view showing the pillows for supporting the ends of the tie. Fig. 2 is a plan view of the mechanism shown in Fig. 1. Fig. 3 is a section, on the line 3-3 of Fig. 1, looking in the direction of the arrow. Fig. 4 is a detail view, showing in perspective one of the pillows or spring devices. Fig. 5 is a perspective showing another form of pillow. Fig. 6 is a fragmentary section showing a special form of fastener, which may, if desired, be employed in connection with my improved tie. Fig. 7 is a detail view, showing in perspective a bolt forming apart of the fastener appearing in Fig. 6. Fig. 8 shows in detail a key used for locking the fastener in position. Fig. 9 is a fragmentary elevation showing a form of my improved tie differing slightly from the form appearing in Figs. 1 to 3 inclusive. Fig. 10 is a section, on the line 1010 of Fig. 9. looking in the direction of the arrow.

A web 11 is integral with a base 12, these parts together constituting the body portion of the tie, as may be understood from Figs. 1 and 2. web portions 13 and with flange portions 14, the latter being merely continuations of the web 11 and base 12. The ends of the tie are bent upwardly and inwardly, toward each other, as indicated in Fig. 1, so that the tie as a whole suggests roughly the form of a flattened C.

The base 12 is provided with two spurs 15, made preferably by merely shearing portions of the base without severing them, which are employed to prevent creeping of the tie in the general direction of its length.

A tie rod 16 is provided at its ends with' eyes 17, and by bolts 18 these eyes are secured to the base 12. The tie rod 16 extends obliquely over the top of the web 11, and the depth of the tie rod is slightly greater than its thickness. This tie rod is for the purpose of bracing the tie. at its middle portion, and is desirable because the tie, by its tendency to move slightly, is always liable to become centerbound, and when thus affected, the strains upon it need to be resisted.

T he rails are shown at 19, and rest upon the reverting ends of the tie, being held in position by fasteners 20, 21. These fasteners are alike, and may be understood more particularly by reference to Figs. 6,

7, and 8. Each fastener 20, 21 has the form of a stout leaf spring, bent back upon itself, as shown in Fig. 6. The dotted lines in this figure show the original form of the fastener which, as indicated in full lines in. this figure, is compressed or squeezed, and its two divergent portions are held together by a massive bolt used for the purpose. This bolt is provided with an angular head 23, and with a threaded portion 24; also with a groove 26. A key 27 extends through this groove, and also through a notch 27 with which the fastener 21 is provided.

A. nut 28 is fitted upon the threaded portion 24, and a lock nut 29 is also fitted upon this portion and adapted to engage the nut 28.

Extending through the web 11 are two bolts 30 which are provided with nuts 31, as may be understood from Fig. 3. Encircling each bolt 30 are two eyes 32, and integral with these two eyes is a web 33 of stout spring material provided with spring'fingers 34, 85, which are bent in opposite direc- The tie is provided with g I p 1,115,227

tions, as indicated in Fig. 4. The web 33 is further provided with a slot 36, one edge 37 of this slot resting directly upon the web 11, as shown in Fig. 3, in such manner as to re- .lievethe bolt 30 of undue strain. That is to say, the downward pressure upon the web 33 is carried by the upper edge of the web 11 rather than by the bolt 30. The Web 33, with its spring fingers 34 and 35, constitute a pillow, or massive and strong spring. When the parts are assembled, the spring fingers 34, 35 engage the inner surface of the flange portion 14 and are located directly below the rails 19, as indicated in Fig. 1.

When great pressure is placed upon the rails 19, by the passage of trains thereover, the ends of the tie tend to bend downwardly,

and in doing this, the spring fingers 34, 35 are bent slightly. The ends of the tie are thus effectively cushioned. In some instances, as indicated in Fig. 5, I provide two separate spring fingers 38, 39, and locate the same upon opposite sides of the web 11, se-

vided with anotch 45. Located within this notch are two spring fingers 46, which are secured to the inner flange l2 by bolts 47 and nuts 48. The stiffness and resilience of the spring fingers 46 allow the ends of the tie an adequate amount of spring play, due to vary ing pressure upon the ends of the tie.

I do'not limit myself to the precise mechanism shown, as variations may be made therein without departing from the spirit of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is as follows:

1. In a railroad tie, the combination of a metallic bar provided with reverting ends and with means for supporting the rails upon said ends, and a tie rod secured to said tie and extending upon opposite sides of the proximate middle thereof.

2. In a tie, the combination of a metallic body portion provided with reverting ends and further provided with a web, and a tie rod extending across said web and secured with its ends'upon opposite sides of said web.

3. In a railroad tie, the combination of a body portion provided with reverting ends and further provided with a web, a tie rod extending obliquely across said web, said body portion beingprovidedwith spurs in-' tegral therewith for preventing longitudinal travel of said tie. i

4. In a railroad tie, the combination of a metallic body member provided with reverting ends, means for supporting the rail upon said revertingends, and resilient metal pillows consisting of a straight lower portion with a base, and said ends being provided with flanges which are continuations of said base, and pillows mounted upon said body member and provided with portions loosely engaging the flanges of said reverting ends.

6. In a railroad tie, the combination of a metallic body portion provided with reverting ends, spring mechanism connected with said body portion and provided with curved portions extending into loose engagement with said reverting ends, and means for mounting rails upon said reverting ends, at points adjacent points of engagement of said spring mechanism therewith.

7. In a railroad tie the combination of a metallic body member provided with revert,-

ing ends, spring mechanism connected with the body portion, said spring mechanism consisting of a base portion adapted to be secured to the body portion, and vertical curved fingers adapted to engage the under face of the said reverting ends.

8. In a railroad tie the combination of a metallic body portion provided with reverting ends and further provided with a web, spring mechanism connected with the body portion and adapted to engage the said reverting ends, said spring mechanism comprising a base member adapted to be secured to said web and vertical curved fingers adapted to engage the under face of the reverted ends.

9. In a railroad tie the combination of a metallic body portion provided with reverting ends and further provided with a web, spring mechanism connected with the body portion and adapted to engage the said reverting ends on each side of the web.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
