RAILWAY-Tl E.

SPECIFICATION formingpart of Letters Patent No. 281,806, dated July 24, 1883.

Application filed March 24, 1883.

To all whom it may concern Be it known that I, Annrson It. SPAULDING, a citizen of the United States, residing at Lake City, in the county of \Vabasha and State of Minnesota, have invented certain new and useful Improvements in Railway-Ties, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to improvements in railway-ties; and it consists in the novel construction and arrangement, all as will be hereinafter more fully explained.

The annexed drawings, to which reference is made, fully illustrate my invention, in which Figure 1 represents a plan view of my device. Fig. 2 is a vertical sectional view of the same, and Fig. 3 is a cross-sectional view taken through line 1 y, Fig. 2. v

Referring by letter to the accompanying drawings, A designates a railroad-tie c011- strueted preferably of metal, having a longitudinal channel, a, extending the entire length, and in cross-section the tie is of H form, thereby saving material in its construction, and at the same time affording a strong and durable tie. At each end and 011 the upper face the tie is provided with a transverse dovetail groove, b, in the bottom of which is seated a cushion, 0, having bevel sides to correspond with the shape of the groove, as shown in the Upon this cushion c, and within vided with notches e in each side on its basefiange to receive the pointed end f of asliding latch-key, g, which latter is seated and slides within a longitudinal dovetail groove, h, on opposite sides of the groove 1), as shown. Adjoining the said groove, and on'opposite sides thereof, are formed shallow dovetail grooves 'i, to receive a wedge-key of metal, as at 70, which is provided on one side withnotches Z, in which the point m of the sliding latch g engages. Within the said groove, and in rear of said wedge-key 7c, is placed a wooden wedge-shaped clamping-key, n, that binds and firmly secures the slide 9 and key 75 when the same are in position.

On the under side of the tie A, and directly beneath the rail seat or groove Z), at each end thereof and within the channel a, I provide a recess, 0, to receive a cushion, p, of any suitable material, whereby jarring or shock caused (No model.)

drawings that in looking the rail to the tie the operationis very simple, and can be quickly done after the rail is seated upon the cushion and within the groove 1). The slide-latch is placed in position, with its point f engaging the notch e in the rail, while the opposite point, m, enters the notch in the metal key k, after which the wooden wedge-keyn is driven home and a spike or nail, q, driven in the narrow end, thereby preventing the wedge n from working loose by said spike coming in contact with the edge of the tie, as shown in the draw ings. Again, it will be seen by reference to the drawings, I economize in material by taking off the edges and corners of the tie, and channel the same underneath, and yet preserve a strong and durable tie, and the packing ma terial and wooden keys give sufficient elasticity to the rail to allow contraction and expansion due to atmospherical change.

The tie can be made any desirable size and of any suitable metal, cast whole or in sections and riveted together, galvanized or coated with other substance for preservation, and the rubber or other cushion may project somewhat beyond the sides of the tie. Furthermore, it will be noticed that my railway-tie is so constructed that by means of the clamping wedges and slide-latch the rail is held firmly in place, the parts easily and quickly separated when desired to detach the rail from the tie, and at the same time is cheap to manufacture, and is light to handle.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The combination, in a railwaytic channeled 011 its under side, forming 5 1) shape in cross-section, and provided with recesses 0 0, to receive the cushion, and having on its upper face a transverse dovetail groovef b, in which is seated the cushion c, of the latch-keys g,

wedge-keys K, and clamping-key n, sliding in dovetail grooves h z, formed 011 the upper face of the tie, as sh wn and described.

2. A railway tie provided on opposite sides of the rail seat with dovetail transverse grooves i, to receive clamping-wedges 70 n, and longitudinal dovetail grooves h, to receive the slide-latches 9, whereby the rail is removably locked to the tie, as shown and described.

8. The combination, with the rail and tie having transverse grooves i and longitudinal grooves h, of the slide-latches pointed at both ends, one end to engage the notch e in the rail, and the opposite end to engage a notch in the metal key is; the latter clamped against the IO slide by the wooden wedge n, as shown and described.

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