.SON, of Lsnsdownc,-Delawcre county, and

SAMUEL G. THOMSON; of Altoona, Blair county, Fennsylvcnic', have inventeda new and useful RoilrJoint, of which the following is a full, clear, and exact description, referonce being had to the accompanying drowings, forming part of this specification, in which- Fi 'ures l, 2, 3, 4i, and 5 are cross-sections of joints constructed in accordance with our invention, and Fig. 6 is a detail view of a slotted washer which we may employ.

{Bur invention relates to that cliiss 'of rail woy' joints which are connected with splice bsrs or angle-burs, and it is designed to pro-' vide on improved splice-bur and joint cine oloying such bars. l loretoforc in such splicears or angle-burs the web portion between the head and base of the mil has been substsn'tielly vertical and the securing-nut bears directly against the vertical outer face of thc splice -bsr. We have discovered that by using a splice-bar having it web which is in clincd or curved downwardly and outwardly we can obtain 9. stiffer and stronger angle-bar and joint with less amountof motel than in the. ordinary T his outward inclination or curving of the web enables us to use bot.

tom flanges on tho angle-bar, thusgiving substontislly c T-rcil section.

Another important feature of our invention consists in providing an cnglcrbar or splice-bar with a flange which depends below the rail-base, the upper web being outwardly inclined or curved. in such case the slantv ing web acts cfhcicntly to transmit the strain around the roil-foot to tho depending flange,

and thus eliminates or grr stly rcducos tho tendency of an angle-bar with a depending flange to buckle in the middle portion fitting the top of the fopt of the rail. in this case the slanting web also enables the metal to being a deep splice-bar with concentrated in the top of tho bar and the lower part of the depending flange, thus givgreat stiffness for the amount of metal used and without any tendency to buckle.

In the drawings, referring to Fig. 1, 2 represents (the hood, 3 the web, and 4 l the buseflangcs of the rail. The splice-bars are pro vided with a head?) and outward ly and downwardly inclined webs 6 and an outer base dang? 7, which ms on the upper face of the rail use. The splice-bar is also provided with an inner'base flange or rib 8. On acobly employ 2i washer 9 between the nut 10. and the single-bar, which washer is inclined on its inner face and has a flat outer face. The head 11 of thcboltis also preferably shaped on its inner face to fit the web of the other 'splicebar.

In Fig. 2 weshow a form similar to Fig. 1, except that the bars are provided with depending flanges 12, extendin below the railbase. We have. shown the i angcs 12 in this form as inwardly inclined and provided with an enlarged head or rib 13 along the lower edge. It will be understood, however, that tion and be of any desirable width and shape rind may havoeither a. singlor double rib or made without .a rib. Inthis figure parts similar to Fig. 1 are designated by the some numeral with the letter it applied.

In, Fig. 3 we show a form similar to that of Fig. 2, except that tlic'ilengrs 12 are curved to prcscnt a convex inner face. .In this form thc letter b is applied to the parts desig- In this form we shbw a washer 14 between the head of tho bolt and the corresponding anglebnr, and it will be undortsood that this washer may be employed in any of the forms to avoid the use of a special head on the bolt. In F ig, 4 we show a form similar to Fig. 3, except that the depending flanges 12 are curved outwardly to. present a. convex outer face. In F ig. 5 we show a form similar to that of Fig. l, cxccpt that the inner portion of 'the head .5 is removed, the web extending from the base. plied to the parts corresponding to parts of the.prcccdingfigures. '1 v The advantages of our invention result from the use oi the downwurdl and out- Rvcrdly inclined or curved web 0 the spliceber. 'lhisgivcs a much better distribution ()f.1118l18.l and makes a stif'icr bar than fornierly for the some amount of metal; It also presents a better sectional form. Where the depending flange is used, the slanting web the inner tr o-c oi the-head directly down into.

in lll'll iorm the letter -d s aptransmits the strains more directIy-.-and etficount of the inclination of the web 6 we preferthe depending flange may extend in any direcnoted by numerals similar to that ol Fig. 1.

l ciently and prevents the tendencyof the bar-' to buckle in its middle portion fitting the top of the footof rail. The slanting web also prevents the bolt from turning, thus avoiding the use of elongated holes in the bar. If the 5 beveled washer is used under the head of the bolt, such washer can be slotted or punched to' revent the bolt from turning' The was er may have an inclosed hole or may be open at one side and may be of suflicient 0' length to provide holes or slots for two or more bolts.

By the word inclined,in the claims we I intend to cogrer either a straight inclined or curved surface.

I 5 Many changes may be made in the form,

shape, and size of the bar, the depending flange maybe used or not, as desired, and other changes may be made without departing from our invention.

2o Although weshow our invention as applied to'the ordinary'form of T-rail, we intend to cover the same when applied to any type'of rail, especially girder or street-car rails.

We claim 5 1. A rail-joint having a splice-bar with an outwardly and downwardly inclined boltingface, said spmze-bar constituting in itself the one side 0 the joint, andbo'lts" extending horizontally through the splice-bar; substan- ,0 tially as described. 4

2. A rail-joint havinga splice-bar with a head, a foot and a downwardly. and outwardl' inclined web, said s lice-bar forming in itse f the one side of the ra1l-joint, and bolts 5 extending horizontally through the splicebar; substantially as described.

3. A splice-bar havin an outwardly and downwardly slanting we and provided with a flangearranged-to extend below the rail- 0 base; substantially as described.

4. A splice-bar having a head and foot, with a downwardly and outward 1y inclined .web', the foot having a depending flange arranged to-extend below the rail-base; substan'tially as described.

5. A s lice-bar having a downwardl and outward yslanting web, an outer baseange, and an inner base rib or flange; substantia ly as described.

6. In a rail-joint, a splicebar having an outwardly and downwardly inclined boltingface, awasher arranged t0 -fit 'against said. face and having a flatouter face, and a bolt extending through the bar and washer; sub stantially as described. 7. In a rail-joint, anangle-bar having a curved or inclined outer face, and a slotted washer arranged to fit against said face and having an outer vertical gripping-face; substantially asdescribed: 1 6o 8. A s lice-bar having an inclined bolting T web and provided with. depending flange having a rib or enlargement along its lower portion substantially as described.
