RAIL-TIE.

Specification of Letters Patent.

Patented Oct. 3, 1905.

Application filed March 15,1905- Serial NO. 250,255-

To It whmn it may concern:

Be it known that I, HENRY DE FORD, a citizen of the United States of America, residing at Hardwick, in the county of Caledonia and State of Vermont, have invented new and useful Improvements in Rail-Ties, of which the following is a specification.

This invention relates to rail-ties, and has for its object to produce a simple inexpensive device of this character which will be exceedingly strong and durable,one which will be practically free from expansion and contraction due to climatic changes, and one which will possess the requisite amount of elasticity or yieldability necessary for heavy trafiic.

l/Vith these and other objects in view the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a vertical longitudinal section centrally through a tie embodying the invention. Fig. 2 is an elevation, partlyin section, the section being taken transversely through one of the ties on the line 2 2 of Fig. 1.

Referring to the drawings, it will be seen that the improved tie comprises an up er member 1, a lower member 2, and an inner lling member or core 3, the parts being connected by members or bolts 4, entered vertically through and adjacent the ends of the tie.

The member 1, which is practically composed of steel or other suitable metal, is of box-like form, comprising side walls 5 and end walls 6, the side and end walls having their inner faces downwardly and outwardly beveled or inclined, as shown herein, while the member 2, which is likewise composed of steel and comprises side walls 7 and end walls 8, has the outer faces of its walls beveled or inclined to coincide with the inclination of the inner faces of the walls of the upper member, into which the lower member telescopically seats.

The filling member or core 3 is composed of wood or other appropriate material and is of a thickness slightly greater than the depth of the member 2, into which it seats, whereby when the member 1 is placed in position over the member 2 it will rest upon and be sustained by the core 3, thus to impart a vertical resiliency or yieldability to the tie requisite for heavy trafiic.

Formed in the upper member 1 at appropriate intervals are suitable openings, through which spikes or other fastening members 9 are entered and driven into the core 3, thus to secure in place upon the tie rails 10.

In assembling the parts of the tie the core 3 is arranged in the member 2 and the member 1 seated over the latter, thus to wholly inclose the core, whereby the tie will be rendered exceedingly durable, it being obvious that owin to the members 1 and 2 being provided with inclined meeting faces they will under pressure be caused to fit tightly one upon the other, thus to exclude moisture from entrance to the core 3. It may be observed that in ractice the tie will be partially embedded which fact, in connection with the members 1 and 2 being secured to the core 3 by means of the bolts 4, will practically obviate expansion or contraction of the tie under climatic influences, thus materially reducing liability of the rails spreading and dispensing with the em loyment of railbraces, and, further, that t e rails may be readily spiked to the ties and maintained securely in osition upon the latter.

From t e foregoing it is apparent that I produce a simple inexpensive tie, which Will be strong and durable and one which while possessing all of the desirable qualities of a solid-metal tie will further have the elasticity requisite for heavy traffic, it being understood that in attaining these ends various minor changes of the details herein set forth may be resorted to without departing from the spirit of the invention.

Having thus described the invention, what is claimed as new is 1. A rail-tie comprising upper and lower box-like members, one designed to fit within the other, said members having the meeting faces of their walls correspondingly inclined, a filling member or core inclosed by the members, and means for uniting the parts of the tie.

2. A rail-tie comprising upper and lower box-like members, one designed to fit within the other, said members having the meeting faces of their Walls correspondingly inclined, a filling member or core inclosed by the members, and connecting members entered transversely through the tie for uniting the parts thereof.

In testimony whereof I aflix my signature in presence of two witnesses.

HENRY DE FORD. Witnesses:
