To all whom it may concern:

Be it known that I, ERT H. HENDER- SON, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented new and useful Improvements in Combined Railway Ties and Tie-Plates and Rods, of which the following is a specification.

This invention, in respect to the tie element, is of that class in which comparatively small blocks of Wood are used with avmetallic structure as supports for the rails whereby the advantages of a timber tie, while presenting a minimum quantity of wood, are secured. Such composite ties also, among other advantages, have those ofstrength, of elasticity, of deadening sound, and of effecting insulation of the rails required when a signaling system is used involving track circuits.

In the improved composite tie which forms a part of the combination forming my invention, the wooden blocks are so ar ranged in their respective pockets that the upper surfaces of said blocks shall project above the upper edges of the metallic tie element whereby to prevent contact of the rails therewith. When the tie is placed on the roadbed and the ballast has been thrown in, there is effected a fast and permanent interlocking engagement between the tie and ballast, holding the tie in position, it being firmly-embedded and anchored so that it cannot move of creep, the construction and result being such that the tie forms a channel to receive and lock longitudinally and transversely With the ballast.

' The element of the metallic tie-plate and rod which enters into the combination constituting this invention is an important factor, not only by reason of its individual construction, but in that it is provided with shoulders which abut against the inner ends of the wooden blocks, whereby retention of the latter in position is assured in a marked degree.

In the accompanying drawings,--

Figure l is a perspective view showing a combination into which enter my improved composite tie and tielate and rod. Fig. 2 is a cross section on t e line 2-2 of Fig. 1. Fig. 3 is a plan view of the sheet metal blank from which the tie in one form is made. Fig. 4 is a top view of the tie-plate and rod blank. Fig. 5 is an enlarged end Fig. 6 is a longitudinal seea fragmentary longitudinal section of a modified form of the combined structure.

a central longitudinal section of Fig. 12 is the tie-plate and rod on the line l212 of Fig. 11, showing the inverted U-shaped character of the central or red member-of said structure.

In carrying out my invention, so far as the structure of the metallic tie is concerned, I take a sheet of metal, preferably steel, which by suitable machinery is stamped out to'form a blank A as shown in Fig. 3, and thereafter by suitable means give it the channel or trough-like shape indicated in Fig. l and other figures. In Fig. 3 the bend outline is represented by the dotted lines. In that figure the lon itudinal central portion is solid as shown y 1, and at the longitudinal center of the blank are stamped out or formed openings 2. Similar but smaller openings 3 are provided near the respective ends of the blank. Certain parts of the outer edges of the blank, and adjacent to the openings 3, are out out as indicated at 4, while at each end of the blank portions 5 are removed, leaving extremities 6. The longitudinal central portion 1 is projected at each end so as to form continuations 7 which preferably extend slightly beyond the extremities 6.

Supposing Fi 3 to represent the inner side of the blank A, points or spurs 8 are formed or projected y suitable means at each side of the blank in the portions 9, near the respective ends of the blank Bolt holes of the structure seen in the 11 .are made in the several parts of the brought to substantially trough or channel shape, each outer end of the tie forming a pocket inclosing and clamping a block of wood 12 which, generally considered, is usual in composite ties of this character. It will be found in Figs. 1 and 2, and understood from Figs. 6 and 11, that the points or spurs 8 at each side of the tie are embedded in a wooden block 12, and that the latter is clamped and additionally secured in the pockets of the channel by bolts 14 which pass through holes 11 and are strained and tightened by means of nuts.

The removal of sections of the blank at 2 provides in the completed structure, in Fig. 1, open sides at the central portion of the tie, and similar removal at 3 results in the formation of smaller openings near the ends of the tie. The function ,of the openings formed at 2 is to permit the entrance of ballast to the body, or what may be termed the interior, of the tie, whereby an effective anchor, lock or obstruction against longitudinal, creeping, or other movement of the tie with reference to the road bed is insured. The continuations 7 also serve to interlock with the ballast, and it is to be noticed that the ends of the channeled portions of the tie project at 15 beyond the outer ends of the blocks 12, and encroach upon the projections or feet 7 for the cooperation of the ballast in the anchoring of the ends of the tie with the road bed. Similar projections 15 of the sides of the channel are provided beyond the inner ends of.

the blocks 12, whereby the ballast resting upon the longitudinal central portion 1 may find its way up against the inner ends of the blocks 12 and be pocketed by the bottom 1 and the projections 15, thereby providing for the embedding and anchoring of the tie at its central portion in the road bed. Thus the tie is embedded and anchored in and held by the ballast so as to become practically an integral part of the road bed, this embedding and anchorage being effected not only at the central portion of the tie, that is to say, between the rails, but also at the ends of the tie or beyond the track.

If desired, as a. part of the means for preventing creeping or longitudinal movement of the blocks 12, a portion of the bottom 1 may be slit at the projections 7 that is to say, the solid projections 7 shown in Fig. 1 may be cut, as indicated in Fig. 8, so as to allow a portion 7 thereof to be turned up against the outer end of the block 12.

The open sided construction of the channeled tie serves also the important purpose of allowing free drainage between the rails, and the consequent protection of the roadbed and the wooden blocks 12. The clamping bolts 14 are intended to draw tightly together the sides of the channeled strucaeeaovo ture, clamping them upon the wooden blocks 12 and causing the effective penetration of the points or spurs 8 into the sides thereof. In Fig. l, and also in Figs. 2, 5 and 6, it will be observed that the blocks 12 extend above the upper edges of the channeled tie, and more especially that the part of the Wooden block upon which rests the tie plate, on which in turn the rail is placed, extends a considerable portion above the inner edge formed at the cut-away portions 4. Thus sufficient space is provided between the foot of the rail and the metallic tie so that any sinkage by wear of the wood cannot result in contact of the rail with a metallic body.

Should it be desired to renew the wooden blocks 12 when worn, it is required, first,

to release the bolts 14:, whereupon the points or spurs 8 may be detached or forced from the wood when, after the removal of the end bolt 14, a block 12 may be withdrawn endwise as will be evident from Fig. 1. In the modification shown in Fig. 8 the turned up portion 7 would necessarily have to be flattened. However, if desired, either block, on the taking out of the ballast at the center of the tie, may be drawn inward and lifted out, it being understood that the obstructing bolts have been removed and the points or spurs forced from their hold upon the wood.

In Fig. 9 a blank similar to that described with respect to Fig. 3, is indicated, the main difference being that in Fig. 9 the central longitudinal portion 1 is lightened by the removal of a central section 2 and also of a section 2 near each end of the blank. These removed portions may be of any desired size and shape and, as is obvious, their removal lightens or reduces the weight of the blank without materially impairing its strength as a tie. This lightened form of blank may have advantages over the more solid form found in Fig. 3, inasmuch as it allows greater facilities for anchoring with the ballast, and also for carrying otf drainage. Either form may commend itself to the practical engineer when considering the character of the rolling stock and the amount of traffic intended to be provided for.

In Fig. 7 such a tie as is hereinbefore described as stamped out of sheet metal, is shown as a casting of steel or other suitable material. The tie, whether stamped or cast, may be galvanized for its protection from exterior influences.

As has been stated my present invention contemplates a com ination between the composite, that is to say, metallic and wooden structure thus far described, and a metallic tie-plate and rod. This combination will be understood by reference, more especially, to Figs. 1, 6, 11 and 12, although shown to some extent in other figures. The tie-plate and rod, generally represented by B, is also stamped from a sheet of metal,

raeao preferably steel, and is indicated in two equivalent'forms in Figs. 4 and 10. In each the central or rod portion 20 of the blank, in the completed structure, is preferably bent to the inverted U-shape shown by 20 in Fig. 12, which is a section. on the line 12-12 of Fig. 11. The outer ends 21 of the tie-plate section proper, see Figs. 1, 4 and 10, are of somewhat extended area, the under side of each of said parts 21 being provided with points or spurs 8 which, as seen in Fig. 6, are embedded in the upper surface of one of the wooden blocks 12. The upper surfaces of the parts 21 serve as the .immediate seatsfor the flanges of the rails C, so indicated in Figs. 1, 2, 5, 6, 8 and 11. The rail having been laid upon the outer end of the plate member 21, certain tongues formed at the end of said plate are turned over upon the respective sides of the flange of the rail whereby to clamp it to the tie-plate and supplement the work of the usual spikes a. Such tongues, in the blank tie plate and rod, Figs. 4 and 10, are shown by 22 and 23. In Fig. 4 the left hand end of the tie-plate proper is seen provided with two exterior tongues 22 and one interior tongue 23, while the right hand end is furnished with one exterior tongue 22 and two inner tongues 23. This system of illustration is to explain that it is optional with me to select the number and arrangement of these tongues. Thus in Fig. 10 each end of the tie-plate has three exterior tongues 22 and two inner ones 23. It will be understood that in Figs. 4 and 10 the bending margins, whether of the central portion of the structure or of the tongues, are indicated by dotted lines. The disposition of the tongues is left to the discretion of the engineer. The length of the tongue 22 or 23 will also be left to his judgment, in view of conditions to be encountered. Thus the tongues 22, 23 may be long enough to reach to the web of the rail, as indicated in Figs. 1, 6, 8 and 11, or have lesser lap upon the flange. It is obvious that these tongues do not interfere with the ordinary spiking which confines the tie-plate member and its superposed rail to the wooden block or cushion 12.

The formation described,'while primarily designed to give to the tie-plate and rod great inherent strength, serves other purposes. Thus, the cavity or channeled under side of the central or rod member of the tieplate and rod 18 receives and pockets a portion of the ballast, the structure thereby being effectually anchored with the road bed. Furthermore, the ends 25 of this inverted U-shaped part of the rod member abut against the iner ends of the blocks 12, thereby cooperating as a lock with the points or spurs 8 to prevent distortion of the track.

My combined tie and tie-plate and rod may be used with a worn out wooden tie by cutting the tie in the center and reversing the ends, the, arts worn in the old tie by the flange of tlie rail not being used for the seat of the rail in my improved structure.

While the use of such points or spurs as 8 or8 is considered advisable and as adding to the efliciency of my invention, they may be omitted if desired.

This invention is believed to constitute a practical improvement consisting of a composite metallic and wood tie in operative combination with a unitary metallic tieplate and rod, the whole structure forming a substantial effective and immovable seat for the rails, and lock with the road bed.

It is my intention to file a separate application for the composite metallic and Wooden tie, and another for the unitary metallic tie-plate and rod, the combination of which two structures froms the subject mat- ,ter of the present case.

Certain details entering into this invention, hereinbefore specifically described, may be varied in manner and form suggesting themselves to the skilled engineer or me chanic without involving invention.

While wood is mentioned as the substance of which the blocks 12 are made, any other material or combination of materials having suficiently the function of wood in this use may be substituted therefor, and therefore where wood is mentioned in the claims it is to be understood that its equivalent is to be included.
