WILLIAM PALLISER, 0F THE ARMY AND NAVY CLUB, FALL-MALL, ENG- LAND, ASSIGNOR T0 JOSEPH VALENTINE'SMEDLEY.
Letters Patent No, 99,5-87, dated February 8, 1870.
IIMPROVEMENT IN RAILWAY-RAIL FASTENING.
l The Schedule referred to `in thse Letters Patent and making part of the same;
To all whom it may concern Be it knpwn that I, WILLIAM FALL-Issa, of the Army and Navy club, Pall-Mall, in the county of Middlesex, England, have invented an Improved Fastening for the Permanent Way of' Railways, partlyapplicable to other pnrposes; and I do hereby decla-re that the following is a full and exact description of the. said invention, reference being `'had to the accompanying sheet of drawings, and to the figures and letters marked thereon; thatis to say- My invention consists of an improved'construct-ion of and mode of securing metallic keysor wedges -for fixing iails in chairs, wherein such wedges are forcedin .by the application of a screw-bolt, of peculiar corn` struction, which eectually prevents `the wedges from working loose by the jarring orvibrating actionfoccasioned by the passing cfa tiain,
Ou the accompanying drawings are shown the v'arions arrangements I employ for carrying Ymy invention into practice.
Figure l shows a sectional pian, and l Figure 2 shows a side ele ation of a railway-chair, A, and ruil B, with one of my improvedarrangements C C are two folding wedges,- ot' which C is pre;
.vented from altering its position relative to the c hair,
by I neans of two .projecting fillets or-tianges c c, as shown.
Each wedge has a groove along its meeting-sur-v face, which grooves `together fonti a hole, c', through which the screw-bo1t 1)-is passed, the hole being so arranged. that the head d of the bolt bears against the broad end of the wedge C', while the nut d b ears against the opposite end of the wedge C.
, From. this arrangement it will be seen, that by screwing up the nut d1 ot' the bolt, after the wedges have been put in position,'ythe wedge C' will he drawn in, and will he causedto.hold the rail firmly in the chair, while any loosening ofthe wedges through vi' brations, is prevented by the screw-boit.
Figures' 3 to 6 show my improved constrnctionof the holt which VI prefer to employ,,in order the more 'securely to hold the wedges.`
For this purpose, the nut d (shown in section at tig.
3, and in front view, at tig.l 4,),is formed with a conical or tapering recess at its .front end`, into which itsa4 tapering or wedge-nut, d, (shown in section at tig. 3,
and in detached side and front views at iigs. 5 and 6,) which is split either` wholly or only at the tapering part. 'iat x. i
The incline or taper of the recess and wedge-nut is such, that when the nut d1 has been screwed uptight, 'und the nut dA is then screwed into the recess, a jamming or wedgiug-action will takev place, whecahy the *Hum nut d (on account of its being split) is pressed forcibly against the screwbolt D, so as to firmly-nip the same, while the uut fl, by being jammed or wedged upon the nut d2, will prevent the latter from releasing its nipping hold on the bolt, even when, by any jarring or vibrating action, the pressure exerted hy the nut d1 againt the wedge orA key, held thereby, is, for certain short intervals of time, entirely or partially removed,and thus the 'unscrewing .of the nut, which usually takes place with ordinary nuts, through such' alternate applying and releasing the pressure in any vibrating action, is entirely prevented.`
In place oi arranging the splitI and recessed nuts, as i shown at fig. 3, their position may be reversed, as shown y at F igure 7, the split nut d, being screwed on tirst,so as to ytake a bearing against the object G, to be secured, andthe recessed nut d bring screwed an over d; or, in place of Athe nut dl, a recessed washeud, may be employed, as shown in section and plau'at Figures 8 and 9; or, again, a conical recess may befforxned in the object C, to he` secured, as at Figure 10, in to which recess the split nut is screwed. i
It will be evident that this 'improved construction of nuts to screw-bolts may be applied with great advantage in all cases .where rails, pluminer-blocksof crank-shafts, the ends of wheel-axles, &c., `I prefer to employ for the purposes of my invention screw-bolts, with reduced Shanks, as previously invented by me, -aud as shown in tig. 3, whereby the breaking of the. .bolt 'at the last/thread', through undue strains; as occurs in ordinary. screwbolts, is prevented, any elongation of the boltj being made to take place in the reduced shank.
I `am aware that wedges have been insertedptoward each other, end to end, but not meeting, from oppo;` .site sides of the chair, and between inclined faces on the inside of the ange of the chair, 4andthe web of the rail. But the lapping'wedges described require less, breadth of ehaiuand may readily be applied to the chairs in ordinary use, the iuclinedices not being l necessary in the tiange of the chair.
I am. also awareyof the use, in connectiorgwth a recessed nut, of a conical washer, split through iapart Vof its length, at several places', but 1 claim, as arrimprovemnt thereon, the washer described, splitat one point, from end ,to end, since, by' this construction, I
vsecure a more perfect'and more powerful spring-action` in' the washer,-and on this .feature it .depends chiey for its utility.
Having thus describedthe nature ot' myinvention,
and in what manner the same vis to beperformed What I claim, and desire to be secured to me by' Letters Patent, is-
the bolts are subject to a jarring or vibrating action, such as for fish-plates, for 1 1. The' lapping or folding wedges C C', arranged other recessed, substantially as and for the purposes between the chair and web of the mil, held in place described. by fillets c, or their equivalent, and tightened by bolt In testimony whereof, I have signed my name to and nut,the bolt passing throughs. recess, c', iu the this specification, in the presence ot' two subscribing inner inclined faces of the wedges, substantiaily as witnesses, this 5th day of June, 1869.
set forth. i f Witnesses: W. PALLISER.
2. The combnationof nut and washer, one, at least, CHAs. D. ABEL, l
of which'is conical, and split, from end to end, and the WM. SHIPWRIGHT.
