TaaZZ whom t may concern.'

, Be it known that We, CHARL'EszM. TRUNDLE.

and EDGAR T. .M1LLs, citizens off-.the United'` ments intRail -.Joints,l of which thefollovvlng is a specification.

5 This invention relates to improvements in rail joints V'of the type inwhicli the rails (are w States, residing at Millville, in the-.county-,o-f.

Jefferson and State offWest Virginia, have,v .lnvented certain new and. useful Improve-v joined without the employment of bolts, and one of the-objects of' the present invention:

is to provide a 'rail `joint of thistype -ofsuch construction that; the use l oflxboltsis entirely obviatedl 4asf-Wellas-the use kofkeys, pins,A oriiotherinitially loose and sepa-rate fasten-- ing elements-for connecting the fish plates tothe ra-ils, the. invention contemplating the employment of means-at alfl times fixed With relation'to the rail ends, for so securing the parts.

.Another object of the,V invention is to provide anovel construction [and arrangement l f of the fish plates such that the plates may-be necessary Where such elements are separate;

readily loosenedandf removed by merel'y striking one end thereof and without disturbing the lconnecting-elements with 4vwhich' they have been associated, Which, l1oWever,`-Iis from the railsV andf fish-plates as-isAv-.usually the case. f

Another object ofthe' invention (is to Apro-` vide a rail joint so constructed'that by merely extracting thejspikes Which-secure the fish plates to the ties, the fish plates may be completely separated from the `rails by merely striking one end of each plate, thereby greatly facilitatingthe application and removal of the fish plates to and from the vrails. l

Figure 3 is a vertical transverse sectional view taken substantially on the line 3 3 of Figure 1, looking in vthe direction indicated by the arrows.

The rails, indicated in the draivingsrbythe numeral 1, Vcomprise the usual base flange 2, Web 3, and head 4, and the rails do not differ from ordinary rails except that their customary bolt openings 5 are roccupiedf'by the intermediate portions of doubleended. studs. which arel indicated' in general by. the numeral 6 and constitute-,the means for holdingthewfish plates, indicated-by the numeral 7, to the y rail lends. studs 6 vcomprises ashank 8.5 formed at a Each of the pointinidway bet-Ween' its ends WithVVacy-- f lindrical-,enlargement 9 which is forcedinto position Within the-respeetiveopening 5 and,-

The fish plates 7 are vof counterpartconstruction `kand,so.ffar astheiry general contour isconcerned, do notjdifer from `fishplates nowin use, leach .plate kcomprising the usual upstanding-body portion Tr12V fordisposaleagainst'lthe Websv` of the' rails to be' joined., and the-usual basejflange 13 to rest i upon'vtlie b-as'eflanges ofthe 'said rails,;thef lbase flange ofeach `fish platefbeing .provided with i the usual -ynotches 14 `to` accommodate the spikes 15 which are driven through the usual tie plate 16 and into the ties to secure the sh plates in place.l Each fish plate is formed with aV suitable number of openings to receivethejheaded projecting ends lof the studs 6, and each opening, indicated by the numeral 17, is preferably of the elongate form shownin Figure 1 of the drawings, the openings being of a height greater than the diameter of the heads 10 of the studs Vand of a' length preferably somewhat greatparallel to and between the upper and loWer edges of the body portion 12 of the fish plate. The outer face of the body portion 12 of the fish plate is formed With a recess 19 at that end of the opening 17 from which the extension 18 extends, and the side Walls of the recess, indicated by the numeral 20. are beveled so as to provide Wedging faces above and below the extension 18, these faces gradually merging with the 1outer face of the bodyvmember 12 of the fish plateat a point adjacent the end of the extension 18 and the angular disposition of the faces the drawings.

being substantially the same as the faces 11 of the stud heads 10 so that the faces of the said heads 10 may coact with the Wedging faces a() When the fish plate is disposed vagainst the sides of the rails and slid into the position shown in Figures 1 and 2 of lltwvill be observed by referencey to Figure 2 of the dra-Wings that when the fish plates are disposed against opposite sides'of the meeting ends of two rails to be `oined the corres Jondino Wedoinfr faces 7 b b 2D 20 beside the openings 1T Will occupy parallel vertical planes coincident with the planes occupied by the inclined or oblique faces 11 of the heads 10 of the studs 6, when the fish plates are slid to bring the said faces 2O into Wedging engagement with the faces 11. In assembling the fish plates With the rails,

,the fish plates are, ofcourse, first disposed so that the heads of the studs Will projectr through the openings 17 and the fish plates are then slid longitudinally, 'thel plates being, however, slid in opposite directions due to thel reverse inclination of the faces 11 of the heads of the studs.

have been shifted as far as possible, manual-` When the plates ly, each plate is struck one or'more blows withv a Sledge, at that end toward which the thereby firmly Wedging the faces 2O into engagement With the faces 11 and firmly binding .the fish plates to the rails. The spikes 15 are then driven intoplace-randf in this manner the rails are firmly joined at their meeting ends and securely held against any relative displacement .which would throw them out of alinement.

It Will be evident that in order to remove the fish plates, it is lonly necessary to Withdravv the spikes 15, whereupon a bloT may be struck against that end of each fish plate opposite the end referred to above so as to shift the plate out of engagement with the heads of the studs.

Having thus described theinvention, what We lclaim is:

1. A rail joint fastening consisting of a stud having a' medial cylindrical enlargement andsimilar heads at opposite ends, Ythe inner faces of the headsbeing para-lleland reversely inclined. p

'2. A yrail joint comprisingadjacent rail ends having openings in their Webs, a stud for each of the openings secured therein by, a medial cylindrical enlargement and having similar heads at vopposite ends with their inner faces parallel and'reversely inclined,

veo

and fish plates at the sides of the jointpro-- openings constricted and the outer side of the fishplate recessed at each side ofv the constricted portion of the openings and longitudinally inclined to correspond with the inclined face of the adjacent stud head to coact therewith by a Wedging action.
