and thoroughly efficient in operation, and

which will be so constructed as to be possessed of the resilient qualities found in the ordinary wooden tie to thus support the rails in like manner.

The invention has as a further object to provide a metallic railway tie wherein the ends of the tie in use, will be capable of free vertical movement to thus give under a heavy load and wherein resilient means will be employed for holding the ends of the tie in normal position, the said means coacting to maintain the rails in engagement with the tie, and being disposed to absorb the, shock of aload passing over the tie.

A further object of the invention is .to provide a metallic railway tie of substantially skeleton construction and wherein the resilient means employed for maintaining the ends of the tie in normal position will form a closure for the tie at its upper side and will be arranged to fulcrum upon the tie in such manner as to normally hold the means provided for connecting the rails with the tie in engagement with the rails.

A still further object of the invention is to provide a tie of this character wherein a single resilient means will be employed for maintaining the rails in engagement with the tie and for absorbing the shock of a load passing over the tie. And the invention has as a still further object-to provide a tie of this character which will be simple in construction, which may be easily placed in position within the road-bed, and which will be provided with means for engagement with the rails of such character that the use of spikes or other similar type offastening devices may be dispensed with.

With these and other objects in view my Specification of Letters Patent.

Application filed November 10, 1914. Serial No. 871,310.

invention will be more fully described, illustrated in the accompanying drawings and then specifically pointed out in the claims which are attached to and form a part of this application.

In the accompanying drawings :Figure 1 is a perspective view of my improved tie showing the rails operatively connected therewith, the said rails being broken away, Fig. 2 is a horizontal sectional view taken through the tie and particularly illustrating the peculiar formation of the rail chairs carried by the tie as well as the clamping plates employed for connecting the rails with the tie, the rails being shown in section, Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 2, the portion of the rail shown being broken away, this view particularly illustrating the manner in which the clamping plates engaging the rail engage around the rail chairs of the tie, Fig. 4; is a perspective view showing the seve'ral parts of the tie detached but in proper operative position, and Fig. 5 is a transverse sectional view showing the manner in which the sections of the tie are hingedly connected with each other.

Corresponding and like parts are referred to in the following description and indicated in all the views of. the drawings by the same reference characters.

The body portion of my improved tie indicated at 10 in the drawings, is preferably formed of suitable metal and in order that the said tie may be relatively light, it is of skeleton or channeled construction, the said tie including a bottom wall 11 and side walls 12 which extend at substantially right angles to the bottom.

As best shown in Fig. & of the drawings, the body portion 10 of the tie is formed of hingedly connected sections 1?) and 1%,. each of said sections, at its outer end, being laterally enlarged as at 15 to provide a tread. Preferably, the tread 15 of each of said sections is provided with an outer concave face 16 as best shown in Fig. 2 of the drawings, this construction facilitating. the engagement of the tie with the road-bed.

Formed within the sections1'3 and 14 at the inner extremities thereof and upon opposite sides of the said sections, are vertically arranged shoulders 17 and 18, each of said shoulders extending medially of the adjacent section transversely thereof and being provided with a flat end wall 19, the flat end walls of said shoulders confronting each other when the sections are operatively connected together asillustrated in Figs. 3 and 5 of the drawings.

The upper ends of the shoulders 17 and 18 terminate in spaced relation to the upper edges of the side walls 12 of the sections 13 and 14 and are preferably rounded in cross-section as shown at 20, this being for a reason which will presently appear. Formed on the end wall 19 of the shoulder 18 adjacent the base of the said shoulder, is a laterally extending stud 21 which is disposed to engage within a suitable aperture 22 formedin the end wall of the shoulder 17 In this manner, the sections 13 and 14 are hingedly and detachably connected together and in order to prevent dirt or other foreign matter from gaining entrance within the tie, the bottom wall 11 of each of the sections adjacent the shoulders 17 and 18, is provided with a laterallyextending flange 23 disposed to overlap the adjacent portion of the bottom wall of the opposite section while oppositely disposed side walls 12 of the said sections, at their inner extremities are each provided with a similar flange 24 disposed to receive the adjacent terminal of the corresponding side wall of the opposite section.

From the above description, it will be seen that the body portion of my improved tie is relatively light in construction, this being a very desirable feature in a tie of this character, since the said tie may thus be readily transported for use and it will be observed that when initially placing the tie within the road-bed, the sections thereof may be detached to be inserted beneath the rails from opposite sides of the road-bed and thence connected by inserting the stud 21 within the aperture 22. Consequently, in the construction which I provide, I gain, in thus being able to place the tie within the road-bed, an advantage over the ordinary wooden tie and shall now proceed to describe the construction whereby I attain, in my improved tie, the resilient quality disposed to cushion the load upon the tie, possessed by the ordinary wooden tie. However, before proceeding with such description, it may be stated that in order that snow or water may be prevented from standing within the tie, the upper faces of the bottom walls 11 of the sections 13 and 14 are preferably inclined toward the outer ends of the said sections as best shown in Fig. 2 of the drawings, so that moisture will drain from within the tie. v

Extending transversely above the treads .15 and supported by theside walls 12 are chairs 25, the said chairs being integrally formed with the side walls while the said 2 rails 28 are disposed to seat upon the upper.

flat faces 27 of the chairs 25 and are engaged by the shoulders 26. I Embracing the chairs 25 and engaging the base flanges of the rails 28, are coacting clamping plates 30 and 31, the said plates being shown in detail in Fig. 4 of the drawings. More particularly, the plates 30 are each formed from apiece of suitable resilient metal and include outwardly diverging and longitudinally extending flanges and 33, the flange 33 be ing preferably wider than the flange 32. As best shown in Fig. 2 of the drawings, the flange 32 of each of said plates is disposed to engage over the adjacent side of the base flange of one of the rails 28 with the flange 33 embracing the adjacent chair 25 and disposed within the seat 29 thereof. The clamping members 31 are also each preferably formed from a suitable piece of resilient metal and each of said members at one extremity thereof, is provided with a terminal longitudinally extending flange 34 disposed to engage over the base flange of the adjacent rail upon the outer side thereof and extending from the said flange is a resilient longitudinally curved arm 35 which fits around the curved face 28 of the adjacent chair to extend over and engage the flange 33 of the adjacent clamping plate 30, it being observed upon reference to Fig. 2 of the drawings, that the flanges 33 of the plates 30 are transversely curved to conform to the curvature of the adjacent walls of the seats 29 as well as the curvature of the arms 35 so that the said arms will bear against the said flanges throughout their entire length.

The arms 35 of the members 31 are preferably of such length as to extend at the adjacent extremities thereof above the up per edges of the side walls 12 of the tie and terminate in longitudinally extending and laterally disposed hooks or flanges 36, the free extremities of which are arranged to project downwardly toward the tie. Engaging the said hooks is a combined locking and closure member 37 The closure plate 37 is preferably formed from a single piece of relatively heavy resilient metal, and, as

shown in Fig. 4 of the drawings, is longitudinally bowed. Formed on the member 37 at the extremities thereof, are transversely extending hooks or seats 38 which are disposed to receive the free terminals of the hooks 36, the member 37 being of a length to extend between the said hooks-and being of a width to fit snugly between the side walls 12 of the tie to close the tie upon the upper side thereof.

In assembling the several parts of the tie, the sections 13 and 14; thereof, are oper atively connected in the manner heretofore described and the clamping members 30 are then arranged in position for engagement with the rails 28 as shown in Fig. 2 of the drawings. One of the clamping members 31 is then applied in the manner heretofore explained, and the terminal hook 36 thereof is engaged with the adjacent extremity of the member 37, it being observed that the said member is disposed to fulcrum substantially midway its ends upon'the shoulders 17 and 18 which are accordingly provided with curved faces 20. The free eX- tremity of the member 37 is then bent downwardly between the side walls of the tie and the opposite clamping member 31 is then engaged with the adjacent rail and the arm 35 thereof is inserted between the adjacent end of the member 37 and the contiguous member 30, whence the hook 36 of the said arm is then engaged with the adjacent seat 38 of the said member. It will be observed that when thus in position, the member 37 will be held substantially straight, the resilient action of the said member normally tending to force the arms 35 of the members 31 upwardly into engagement with the curved faces of the chairs 25 and with the flanges 33 of the members 30. As will be obvious, such action of the member. 37 will cause the flanges 32 and 34 of the members 30 and 31 to firmly engage the base flanges of the rails28 to thus securely clamp the rails to the tie.

Attention is now called to the fact that a load passing over the rails 28 would tend to force the extremities of the tie clownwardly against the road-bed and owing to the fact that the sections 13 and 14 of the tie are hingedly connected, consequent vertical movement of the tie will be permitted. However, it is to be noted that the member 37 is disposed to normally maintain the sections of the tie in alinement or in proper horizontal position and any load upon the rails 28 tending to depress the extremities of the tie will be communicated directly to the said member which by its resilient action, will cushion the impact of the said load.

The tension of course, be determined upon experiment but since the resilient action of the tie in cushthe member I can, of

ioning the load is entirely dependent upon the said member, it is preferable that the member be relatively heavy so as to normally exert a considerable tension upon the clamping members 31. It is to be noted that in the provision of the clamping members 30 and 31 that the necessity of spikes or other similar type of fastening devices is obviated. At the points where the meeting ends of the contiguous rails 28 occur, the said meeting ends may be arranged medially of the chairs 25 to be thus held in position by the members 30 and 31, thus obviating the necessity of fish plates.

It will thus be seen that I provide a metallic. tie which will be relatively light in construction but which will through the provision of the member 37, which is disposed to coact with the hingedly connected sections 13 and 14 of the tie, be possessed of the resilient qualities in cushioning the load, found in the ordinary wooden tie. It will further be seen that in the provision of the member 37, the sections of the tie will be resiliently held in normal position while the said members will also coact with the clamping members 30 and 31 to maintain the rails firmly seated upon the tie.

While I have illustrated and described the preferred embodiment of the invention, still, it will be readily understood that the construction disclosed could readily be formed from suitable sheet metal without, in the slightest, departing from the spirit thereof as defined in the appended claims. For instance, the bottom wall 11 of the tie could be formed with reversely arranged and longitudinally extending tongues at their confronting extremities. One of the said tongues could then be rolled upon itself to receive the pivot pin 21 which could also be formed of suitable sheet metal, while the opposite tongue could be similarly rolled to loosely receive the free extremity of the pivot pin. In thus rolling the tongues and providing a sheet metal pivot pin of a relatively large diameter, it will be clear that the rolled portions of the tongues will provide shoulders similar to the shoulders 17 and 18. Further, the chairs 25 could each be formed from a length of suitable sheet metal provided at its extremities with reduced flanges or lugs disposed to engage over the side walls of the body of the tie, the intermediate portions of the piece of metal forming the chair being rolled inwardly to provide the curved lower face 28 and the seat 29.

l/Vhile I have shown the clamps 31 as be ing each provided with a terminal hook or flange 36, still, the said clamps may be formed with a terminal flange or lip ex tending at substantially right angles to member 37 in which event, the terminal hooks formed on the said member would be eliminated. 5
