Y No. 865,945.

To mhmn it may concern.

lle it known that we, Joux Rousn'rs unl .Latins E. Buss. citizens of the United States. residing at Faust, in the county of Franklin and State of New `:'ork. have in vented new and useful Improvements' in Ties. of which the following is a specification.

The invention relates to an improvement in ties,'and particularly to a metallic tie constructed to'provide a firm support for railroad mils. Y

e The main object of the present invention is the pro-` duction of n metallic tie constructed to afford a firm support for railroad mils, and to provide a means for securing the rail in position on the tie, the tie structure including a rail cushioning means arranged to absorb the vibrations of the rail incident to the travel thereon and prevent transmiidori of such vibration tothe tie.

The invention will be described in the following 7 specification, reference being had particularly-to the accompanying drawings, in which:-

Figure l is a plan view illustrating the use of our improved tie, Fig. 2 isa longitudinal section through the tie on line 2-2 of Fig. l, illustrating the preferred form of cushioning means, Fig. 3 is asimilarview illustratinga modified form of cushioning means, Fig. 4 is a plan viewof the tie removed. y Fig. 5'is a transverse section on line 5-50f1fig. 2.

Referring particularly to the drawings, our improved tie comprises a rectangular body 1 formed in the relatively upper surface withacentrally disposed depression 2. Beyond thedepression the tie isapproximately solid to provide heads El to receive the rails, the end walk of the depression being arranged within the mil r11-cking portion of the tie. The depression 2 is of mmc-what less extent transversely and vertically than the simile:- dimensions of the tie,- whereby the tie is in effect of holow construction between the heads.

Each head 3 is formed on 'the relatively upper surface with a mil receiving recess 4. one-half of the recess being formed by undeicntting the maierial of the head, Where-A by to provide a lip 5 oveily'ing a portion of the recess and spiced imm the bottom wall thereof. Between the relatively inner-ends of the lips 5 of the tie, the thickluw of the body l is reduced by a distnnce approxinuitcly equal to the thickness of the lip. so that the inner lmlf of thc rect-m4 is fully open. the inner boundary thcuuf being defined by a unzqmnltively slight shoullder 6. tcntizdly of thc length of the recess l the heads 2t an* zich formed with n vertically extemling'oinning 7 adapted to contain Ille vilmttion absorber. as will puse-nth' uppczir. I'

The iunci' surface of the lip 5 is shaped to conform to tlurllrvntnrc .Jamil buse S, :ind the dcpll of the 11u-css 4- Ilm! i.; tile distance from ilnel itfncr sul'l'me of thc lip Patented sept. 1o, 1907. i

5 to the bottom .wall of the recess is slightly in excess of the thickness of the rail flange 8. A tie plate 9 is arranged to cover the surface of the tie between the recesses 4, the respective ends of mid plate overlying the open portion of the recess and sha pcd. as at 10, to conform to the contour of the base flange of the mil. The tie plate is tro-extensive in width with the width of the tie, thereby covering the depression 2 therein. The tie plate is secured in place by means of bolts 11, shaped at their lower ends to provide hooks 12, adapted to engage appropriately formed openings 13 in the side walls of the depression 2, the upper ends of thi` bolts' being threaded and passed through registering openings 14 in the tie'plate 9, said bolts being secured beyondthe tie plate by nuts 15'to cooperate with the threaded ends thereof.

The openings 7 in the recesses 4 are adapted to contain a means for absorbing to a considerable degree the vibration of the rails, whereby, to avoid transmission of this vibration to the tie with the consequent injurious effect upon the road As shownin Fig. 2 the predrical body of resilient material, as rubber 16, snugly fitting in the openings 7 in the tie with the upper end of the body projecting above the bottom wall of the rece-.w 4. In Fig. 3 the Ashock absorber is shown in the form of' a coil spring 17, seated in the openings 7 and norm-.illy projecting above the bottom of the recesses 4.

The rails are secured in position on the tie in the manner illustrated in Fig. 2, the outer projection of the base flange of the rail being inserted beneath the lip 5; the inner portion of said flange being secured beneath the appropriately formed end of the tie plate l). T hev latter is secured in position by the use of the bolts 1]thercby securing the rails to the tie in a trimmer to provith` a firm support therefor without interfering with the independent movement of the rail essential to its expansion and contraction under changes oi the temp-culture.

The rail rests directly upon thc shock absorbingr bt n'ly, hence materially reducing the tntnsmisdou ot' thc vibration of 'the rail to the tie, and thcrcby avoiding; 'lo :i considerable extent a vibration of thc tic with conscqucnt danxging influence upon th rondbcd. 'lbc uuder surface of flic tie is for-mcd with a wnon'l lot' greater longitudinal extent than that of thc dcpi'ifiou 2, fming in effect a recess for tlwwn-ptiou ci material forming the roadbed, u'lxicli'in plumufill Icnd to prih vent indqiondcnt longitudinal tnovcnlcnl of thc fio.'

In tbe use ofthe tic :isa support forlhc nwclingcnib ofmilroad mils, n'c prcfcr to combine with thv tic' rcinforcing plates l!) dcsigucd to be applied to opposinsidcs of thc u'cb lmrtions of tbc t'cs}mti\'c rails n nilbc wcui'cd to tlnmil und to nich other by bolts '.UfV llni'erred form of shock absorber is in the forni of n cylinlun plates i9 Lire adapted to rest sqimrely upon the lips 5 :uid the ilange engaging purlion ui the ie plate 9, thereby materially minion-ing the rail securing means 0i the tie, While at the sume time securing the meeting ende nf lli-. milfsl in manner to insure their alimentent. under uml-nl cenditions 0i travel. A

The tie uumlr-timed :Le described provides a simrrfle and Convenen: suppnrt for milrlmd rails, in which the vihmlinn rn' the rniis will be absorbed to a material ex- Lent` The .zils may he released al any time by removing the tie plate fi, as will be obvious. i

While preferring the use of duplicate reinforcing plates 19. it is obvinus that only one such plate may be nfwl it' desired. Furthermore, the tie plate 9 may be farmed in une or more sections with independent securing means. The depression 2 maj1 be used to contain a tie ballast, if desired.

Having thus described the invention Wlint. is claimed as new, isz- A tie formed with a central depression. und beyond said depressien with transversely extending rail receivingr rercesses. a portion u! the tiev overlying a part of euch rer-ess. a tie plate extenriing from one ree s to the ether und terminally farmed to ovez'lie :i pox'tiun nf ei-znli reeess. :1nd bolts having removable engagement with tlie walls nl' the dep'ressivn and adapted tn secure the tie plate in plane. in eumbnaiqn with tie reinforcing: plates to lle secured tu the rail and rest upon the rer-ess oxerlying; portions of the llc plate.

In testimony wl1ere0f,'we allx our signatures in presence of two witnesses.
