GEORGE D. I-IILL, .OF LOUISVILLE, KENTUCKY.

BAIL-EASTENING.

To all whom t may concern:

Beit known that I, GEORGE D. HILL, a citizen of the United States, and a resident of Louisville, in the county of Jefferson and 5 State of Kentucky, have invented new and useful Improvements in Rail-Fastenings for Use with Reinforced Railway-Ties, of which the following is a specification.

My invention has reference to reinforced composite railway ties, having new, improved and effective means provided for fastening and retaining the railway rail to the reinforcement in said improved reinforced tie, and consists of a body of any desired form -or shape having embedded therein twisted metal reinforcement of the shape and style shownby the accompanying-draw ing, to strengthen and reinforceithefconcrete or other suitable plastic material, by which this reinforcement must be surrounded in reinforced railway ties of this class, to

said improved Vreinforced 4railway tie, by' means of the novel features hereina'ftenmore sfully described, that-will allow for longif k40 Atudinal expansion and contraction of the rail, and also allow for the gaigeofthe'railway rails being fastened to the j-reinforced railway tie, to be widened when necessary.l The invention will be ibest understood by consideration of the Afollowingdetail de' A `1 scription taken in connection with the 'ac' companying drawing, forming a part of this specication, in lwhich drawinga 4Figure 1 is -a -longitudinal half vertical sectional view of a reinforced railway ftie,`` reinforced 1n any desirable manner. F1g.2

is a vhalf plan top view ofthe rail `fastening and its reinforcement, showing a rail in place in said fastening, anda fastening plate,

having clips attached -to vthe flange yof thei rail ready to be driven vinto place.

lineation of the one section o-r half ,part willl suffice forthat of the other. Fig. 3 is a longitudinal vertical sectional view showing the method and means of fastening and supporting the rail. Fig. 4 is a perspective view of the fastening plate. Fig. 5 is a transverse lcross section of a type of insulated connection `joining together the duplicateparts -cf the reinforcement, showing the two halves of rthe reinforcement electrically insulated from each other. Fig. 6 .is a perspective view of a metallic collapsible form showing one side and one end collapsed.

.Referring to the figures by characters of reference, in whichsimilar characters refer to similar 'parts throughout the several views. the Ymetal reinforcing members 6 consist-of four twisted rods fastened to the rail fastening devices, .and positioned so as to resist tensional stresses, being embedded in concrete or other ysuitable plastic material, as'shown in Fig. 1.

.6 is the `reinforcement with a rail 2 in place in rail fastening 3 with fastening plate 4 rhaving its clips 14 and 15 attached to the Aflange of the rail 2 ready to be driven into splace,.as shown in Fig. 2.

yFor economy of `manufacturing the reinforcement in .the `reinforced railway vtie 6, the metallic 4reinforcement is made in duplicate parts so that the four twisted metallic longitudinal frods 6, forming Apart of the reinforcement, vimay be joined on to corresponding Vends of the duplicate part by means of metallic `joints 7, which Amay be made in any suitable Away. f

:2 is a rail in place.

.3 .represents shoulders -formed in ythe,

flanged shape shown, and fastened Ato fthe reinforcement l6 v'by 'means of rivets 13 yin such .a lway as :to leasilyadmit the flanges of the rail l2 .between the inside faces of these shoulders 3 and at vthe same time allowing the metal fastening -platel4 to vbe applied to the fIianges ofthe rail 2 and the said fastening plate 4 to bedriven'sofas to-be interposed in ftheispace between the inside faces of the shoulders 3 and ythe flanges of the rail 2. The yfastening plate 4 has clips 14 and 15 bent to fit the flanges ofthe rail these-clips 14 and 15 being located at 'two opposite diagonal cornersof plate 4. (See Fig. 4:) r1.[`heou'tsideedgesofclips 14 and ,15 when of reducing to a minimum the jar to which plate 4 will be subjected, by reason ofthe weight or pounding effect of a vehicle passing over rail 2 which is fastened to the reinforced railway tie by means of the plate 4, thus tending to loosen the fastening plate 4 Yfrom between the shoulders 3, a metallic box 16 may be provided (which may be filled with asphalt or other suitable material), said matallic box 16 being fastened to the reinforcement 6 by rivets or bolts 13 underneath the fastening device.

Clips 14 and 15 are loca-ted at two opposite diagonal corners of the fastening plate 4, it being so formed that one of these clips 14 and 15 is thicker than the other, so that being of different thicknesses.

when rail 2, Fig. 3, is placed between the shoulders 3, for the reception of the fastening plate 4, and the fastening plate 4 is driven along the flanges of the rail 2, into its final position, as shown between the shoulders 3, the longitudinal center line of the rail may be to the one side or the other of the longitudinal center line of outside plate 4 by reason of the said clips 14 and 15 This permits Hthe rail to be thrown slightly to one side or to the other of the center line between the shoulders 3, depending upon which way the plate is driven between the sholders 3.

l Thus, if 15 be the thin clip, and 14 the thick clip of the fastening plate 4, the rail will be thrown nearer the shoulder of -the thin clip 15 than it is to the shoulder of the thick clip 14. Vhen both thin clipsof the plate 4 sof the fastening plates, under each rail of this fastening device, in this class of reinforced railway ties-are toward the center line of the two rails so fastened by the fastening plate 4, the gage of the track is standl i Yard; when both thick clips of the two'fasten- Vsary for curves.

ing plates holding each of the two rails in the fastening herein described are towardl the center line of the railway track, the rails are at maximum gage distance apart, necesthe gage of the maximum and standard, is regulated by a graded variety of fastening plates of the general shape shown in 4 with the thickness of clip 14 over that of clip 15 so regulated that it will give the desired gage between the rails. I do not, however,

confine myself to this method alone of ad- This variation, between Ajus'ting for the 'variation of gage of rails on curves when the reinforced railway tie of this class, with the Vrail fastening device herein described, is used. The bolt holes in joint may be fitted with eccentric bushings for the purpose of substantially varying the gage. (See Fig. 5.)

8 is any insulating material placed between the metallic parts of joint 7 and the reinforcement 6.

10 is a bolt of this joint.

'The side 18 and the end 19 of the metallic casting-box form, in Fig. 6, are collapsed, with side 17 standing in a vertical position with reference to its base. The side 17 has vertical slots 2O near each end, and at the proper distance apart for the reception of the shoulders 3 of the rail fastening device, after the duplicate parts of the reinforcement 6 shall have been fastened together by the joint 7, Fig. 2. These slots 20, in the` side 17 of the metallic casting-box form, thus suspend-without any additional support or contrivances for holding same in position-the metal reinforcement in reinforced railway ties of this class, so that the collapsible ends, 19 and 19, and the other side 18 of this metallic casting-box form,

may be moved on their hinges so as to form a receptacle for the retention of the concrete or other plastic material in which the reinforcement must be embedded to form the body of the railway tie.

and 19, to. be collapsed from around the con# crete or other suitable plastic material form- By reason of the sides 17 and 18, and the ends 19 and 19, be-

ing the body of the reinforced tie of this sort, the whole'tie may be removed from the metallic casting-box form, by simply raising the shoulders 3 of the fastening devices from off the slots 20, that is, after the concrete or other suitable plastic material shall have become sufficiently set.

Having fully described my invention, what I claim as new and desire to secure by Lety ters Patent, is
