METALLIC RAILWAY-TIE.

Specification of Letters Patent. Patented Nov, 29, 1910.

Application flled lltay 6, 1909, Serial N 0. 494,430. Renewed July 23, 1910. Serial No. 573,537.

the State of Ohio, have invented new anduseful Improvements in Metallic Railway- Ties, of which the following is a specifica-- tion.

My invention relates to improvements in metallic railway ties, and the object of the same is to provide a metallic railway tie which shall have the following means, ca-

pacities, and advantages, to-wit :-Bases which will properly distributetheloads of trains crossing over the railwayin the construction of which said ties enter; cross pieces which, together with said base pieces and other members, form the body of said tie, which is elastic resilient, flexible enough to bend to passingloads and of suflicient resiliency to recover its normal position and shape after the passing of trams; saidtie having solid load supporting devices between the bottoms of the rails and the base plates of said tie, so as to transmit the weight of the load passing over the rails to the ballast or roadbed without crumpling or deforming the cross pieces-or any member of said tie; rail fastening means which permit the driving and withdrawing of spikes to fasten the rails placed thereon with greater frequency than spikes can be driven in and withdrawn from wooden ties, without injury to said fastening means; pieces and members entering into the construction of said ties that can be rolled by the processes of; rolling mills as now operated; members.,.

which when fabricated or rolled can be assembled at the mill where produced or on the roadbedof the railway.where constructed, without skilled labor and without the use off-machinery; means of insulating rails resting thereon where necessary for signaling purposes; general construction which is cheaper in cost of construction and installa-- tion,. and lighter in weight than metallic ties heretofore made, which willlast and can be made use of for five to six times as long as wooden ties and at the end of thatperiod of use have a value as scrap metal; which can be made of any length so as to accommodate switches and special work when furnished with a sufficient number of rail fastening devices; and having an adjustable rail fastenas shown at A. in Fig ing device so that rails can be laced thereon for any gage of rails, switc es and special work.

In the accompanying drawings WhlCll I illustrate my invention, Figure 1 is a perspective view of my im rov'ed railway tie with sections of rails a ed thereto. Fig; 2 is a perspective view of the channels forming the cross pieces of my tie and the grooved blocks forming the rail fastening device usedwith said tie. Fig. 3 is a vertical cross section of Fig. 2 on the line X-X; A and A being plans of the ends of bushings inserted in Fig. 2 for a bushing when a round spike is used and when a square spike is used respectively. Fig. 4 is a perspective view of-' my improved tie with means of fastening more than two rails thereto, to be used in connection with special work and switches. Fig. 5 is another form of my improved railway tie.

Similar reference characters refer to like parts throu hout the several views.

In the ollowin'gdescription' the term spike is employed .to deslgnateany form of spike driven into the rail fastening device, whether the same have a' shank of round, square or other cross section, or whatever may be the shape .of its head.

In Fig. 1, 11 are the crosspieces of my improved tie preferably made of rolled shapes known as channels, but may be made of any shapes capable of being held between the top and base 'platw hereinafter re ferred to.

2 is a to plate having lugs 2 and a hole 2" and a apted to engage the flanges of cross pieces 1l.

'3 is a base plate havin lugs 3 and a hole 3", said lugs being capa bottom flanges of the cross ieces 11.' y

In Fig. 2, H are bloc s of metal, 'or other solid material. If metal, the same are rolled in bars with the groovebeing a halfcircle, and when blocks 4-4 are placedso that the grooves register, they form an afper ture into which the bushing 5, made 0 rere'ferably of fiber), fits silient material bushin 5 a metallic closely. Inside 0 le of engaging the bushing, 6, is placed. If t e shank of the spike be of round 'cross section, then the bushing. v6 should be a. metallic slit sleeve, 7 .3. If the shank of the spike used to fasten therafls be ofsquare cross section," then bushing 6 is formed of two half-round metallic rods, having a V shaped groove in them, as shown at A, in Fig. 3. As the shank of the spike is round or square, the apertures 7 and 7 are formed in the metallic bushing as shown in A and A.

8 is an insulatin washer of fiber or other insulating materia placed in the aperture formed by the grooves in blocks 4-4 on top of the base plate.

9 is a spike which in cross section is slightly larger than the aperture 7 and 7 in bushing 6 and 6 respectlvely.

10 is a rail of ordinary cross section.

.11 is a sheet of insulating material of any. desired composition adapted to be placed between the rail 10 and the top plate 2.

12 is a key placed in two key- holes 12 and 12" in channels 11. The key is placed in the channels to retain blocks H in position and to resist any tendency of the rails to spread on curves or at any other point in the railway line where force is applied to them laterally to cause such separating. Blocks4-4 may be made in single pairs, 1n which case two half-circle grooves will be rolled in each block; or said blocks 4-4 may be used in two pairs, in which case each block 4 will have a single groove rolled in it. The separation into pairs is shown by line 4-4 in Fig. 2:. The in side of the channel may be serrated, as shown at a, Fig. 2, in which case the outside of the blocks 44c should be corrugated or ribbed, so as to be held more firmly in a given position by the channels -11.

In assembling my improved tie, the channels 11 are inserted in the .lugs of the. base plates, 3-3. The blocks 4-4 are placed approximately at the gage of the rails to be fastened to the ties and the grooves in said blocks H are adjusted so as to form a round aperture. In this aperture, if the rail is to be insulated, washer 8 is placed so as to rest upon base plate 3. Then there is inserted in the aperture formed by the grooves in blocks H the resilient bushing 5 and inside of the resilient bushing, the metallic bushing 6. While the metallic bushing is shown in the drawings as a slit sleeve, it may be formed of a spiral spring or any metallic, cylindrical construction which is elastic and will give and its motion be limited by the sides of the resilient bushing when the spike is driven. into said me tallic bushing. When the bushings are thus in place, the top'plates 2-2 are placed on the cross pieces 11, so as to engage the topflanges thereof, and so that the hole 2'-' in said top plates shall. permit of the passage of the spike to be drlven into the metallic bushing in such a way-that the spike shall not be in contact with the sides of said hole 2. A sheet of insulating material is then placed on top of the top plate and the rail to be carried by my improved tie is placed on the insulating material and the spike 9 to hold the rail in position is driven into the metallic bushing 6 and because of the larger cross section of the spike than the aperture in the elastic metallic bushing, the bushing is spread and becomes wedged and firmly fixed in the resilient bushing 5, with the eflect that the spike is held therein firmly and effectively, the force of the grip of the bushing upon the same being limited only by the area of the cross section of the spike. Practice will indicate the proper cross see tion of the spike, and when of the proper cross-section the spike can be re eate ly driven in and withdrawn'without reaking the shanks thereof, or substantially affect ing the bushing into which said spike is inserted. the bushing it may be withdrawn and again driven in repeatedly and hold the rail in position with the same force and effect substantially as when first driven. In the event that the head shall be broken or sheared 011' of the spike it can be driven into the roadbed of the railway by driving the same through aperture 3 in base plate 3. If the aperture 1n the metallic bushing becomes filled with dirt or gravel or other foreign -material, the same can, with the proper punch or tool, be driven out of the aperture 3 in the base'plate 3.

The blocks 4- when pla'ced between the base plates and the top plate should fit snugly between said plates and rather loosely between the channels 11, so that there will be a continuous metallic support from the top plate to and through the base plate to, the roadbed below'the base plate.

The key 12 is placed through suitable When the spike is thus driven into r holes in the channels 1-1 at points where there is a tendency of the rails to spread on account of lateral stress applied to them and this tendency can thus be checked.

WVhile I have shown the specific forms of base and top plates and cross pieces and blocks exhibited in the drawings forming part of this specification, I do not wish to be limited in the fabrication of my im-' proved tie to the shapes andforms shown.
