RAILWAY-TIE.
SPECIFICATION forming ar. of Letters Patent No. 752753, dated February 23, 1904.
Application filed April 27, 1903. Serial No. 154,384- (No model.)
To all whom it may concern.-
Be it known that I, ARTHUR M. BOWMAN, a citizen of theUnited States, residing at Bellevue, in the county of Allegheny andState of Pennsylvania, have invented a certain new and useful Improvement in Railway-Ties, of which the following is a specification, reference being had therein to the accompanying drawings, forming partof this specification, in which Figure 1 is a view inside elevation of my improved tie, showing the rails in place. Fig. 2 is a plan view of the tie- Fig. 3 is an enlarged view of one end of the tie and rail bearing and fastening device, partly in section. Fig. 4 is a cross-sectional view on the line IV IV of Fig. 3. Fig. 5 is a plan view of Fig. 3, the rail-key and key-plate having been removed. Fig. 6 is an end view of the tie, showing the bearing-plate resting on the upper surface. Fig. 7 is a detail perspective view of the key-bearing plate. Fig. 8 is a similar Fig. 9 is a de- Fig. 10 is a cross-sectional view showing the tie provided with protecting-coverings for the key-holding anchors. Fig. 11 is similar view showing a further modified form of holdinganchor screwed into a nut embedded in the tie.
My invention relates to composite railwayties; and it consists of a tie made of cement, concrete, or other similar substance having an inclosing sheathing or reinforcing surrounding shell, preferably slightly embedded in the materialof the tie, extending approximately throughout its length and adapted tov confine and protect and to firmly hold the entire mass of the structure in one integral piece.
It is well known that concrete structures or bodies acquire great strength and capacity to resist strains of different kinds, and I have utilized these qualities and features with a view to providing a solid and durable tie,with
means for providing rail-bearings and holding elements at a minimum of cost.
Referring to the drawings, 2 is a body of concrete or similar material adapted to harden and set to any desired form in a suitable molding device, with which is incorporated a metallic sheath 3, of expanded metal, wire-netting, or any other suitable material which is adapted to the purpose and having the required confining strength. The sheathing is designed to surroundthe mainbody of the tie, as shown, from one end to the other, a thin outer coating of the concrete covering the sheathing along the sides, top, and bottom to protect it from moisture. It may, however, be entirely on the outside, if desired, and I do not desire to be limited to the exact construction or aring, providing a bonding hold between the concrete and the sheathing, and abutting against the inner surface of the mold, pressure being exerted by any suitable tamping or compressing means.
Various means may be incorporated with the tie for providing bearings for the rails and for securing them in place, and I have shown a plate 4, which is either partly embedded in the concrete at each end on the upper side of the tie or which may merely rest on the top surface, as shown in Fig. 6. The plate is provided with openings 5 for the holding-bolts and at each end with upwardly-extending flanges 6, providing end bearings for the securing-keys 7. The holding anchors or staples 8 are embedded in the concrete, either in the operation of manufacture or separately, being of inverted-U form or otherwise suitably formed to give a good binding or anchoring hold. These holding-anchors maybe of varying forms, as shown in the various details views, and I donot desire to be limited to any special or particular construction, as. it is evident that various forms or means for securing the rail in position may be used with good resultsas, for instance, a holding-anchor having a hook-terminal.
With the form of construction shown in the principal figures of the drawings I prefer to use under-supporting key-plates 9, adapted to fit over the holding-staples upon the plate 4 and to bear against the edges of the railflanges. An advantage of these plates is that they may be made in varying widths to suit varying dimensions of rails, thus permitting of a standard dimension between the holdingstaples, which is of advantage in making the ties of uniform sizes and types. The plates also give good bearing for the holding-keys.
If desired, the holding meansmay be in the form of bolts passed through the tie and held by nuts, as in Figs. lOand 11, inwhich case i I prefer to provide armored openings by using hollow sections-l0, as of pipe, thus permitting of easy removal orrenewal of the holdingbolts. If'desired, however, a single bolt 8", provided with an upper key-eye'll, may be secured by a nut embedded in the tie, as in Fig. 11, thus permitting the bolt to be screwed out and renewed. The anchors may be of the form shown in Fig. 9 or of modifications of such general type. The upper end of the bolts may also be provided with nuts and any suitable clamping devices adapted to engage the flanges of the rail. 1
Various other changes or modifications may be made in the details of constructionor. in the shape, design, proportions, or other features of the invention by the skilled mechanic without departing from it; but all such are to be considered as within the scope of the follow- 1 ing claims. a
What I claim is 1. A railway-tie consisting of a body portion of concrete or cement, and a reinforcing surrounding sheathing incorporated therewith immediately under the surface of the tie, substantially as set forth.
