PROCESS FOR MAKING RAiIl-JOINT BARS:

specially designed for the production of a rail" joint bar having a base section whose central portion is crowned or raised to provide a central IElll; seat or zbase'bearing for the ends of the rails, at the center of the joint, while the remainingportions of the base section of the joint bar are out of contact with thebott'oms of the rails; ii Tothis end the invention contemplates a practical, expeditious" and economical method" of producing rail joint bars with central crowned, or raised, seats for the railends, entirely by 'a novel manipulation ofthe metal in the bar through the medium of roll-passes, so that after the-bar: is cut into rail joint lengths it is only necessary to bend or fold the base section of the bar into its operative plane by 'any' suitable means such for instance as by a press or a bulldozer. 1

'lVhile variousinstrumentalities may be utilized in'carrying out this invention and various designs of rolls and roll-passes may be adapted to the making'of bars according to the present invention, one ofthe Waysfin which the process may be carried out in a practical manner is suggested in the accom panying drawings, in which- Figure 1 is a sectional elevation of a pair of rolls of a rolling mill d'esignedto proj vide two final finishing passesfor giving to the. bar such reductions, distribution-of metal, and-form as contemplated bythe present invention. FigrQf is a sectional view of portion of a folding machine or press that may befemployed'in the final step, after reheating of the bar, of folding or bending the railsupporting'base sect on to its operative plane with respect to the f other members of the joint barl Fig. a side elevation offa portion of the. said folding; machine, portions being broken awayl Figs is an end view'of'a continu vous type of rail joint, the 'jointbars of sp fi n f et rs Pet Patented'Feb. 22, 1916.

which'are adapted to be produced by the hereindescribed process, the view indicating dotted lines the position of the base sec tlon before being folded into its operative plane bythe folding machine or othersuitable means. Fig.6 is a side elevation of a rail. joint with one of the joint bars removed,- to expose the central crowned 'or raised portion of the other bar at the center of the joint. a

The billet or bar blank that is taken up" for final development by the present invention is subjected to a series of roll-passes of knownpform and which secure-the progress ve dlstrlbutlon andreductlon'ofthe 7 metal, and. theigradual shaping'of-the bar," until it reaches a form substantiallyxthat of its final cross-section, wherein the bar includes the main splice member a having a flange member 7' and an integral rail-sup porting base section b formedsimult'ane ously' with the'fiange member and rolled at an angleto its normal operative plane with respect to 'said'main splice member-a of the bar, as may be best seen from Fig. 2 of the drawings. In substantially this design, the metal bar, which is being handled in'the rolling'mill, is 'takenup by the presentprocess" and subjected to the action of passes j formed betweenapair of finishing rolls'A :and B. For the purposes of the present invention'these finishing rollsA and B are designed and constructed to provide between them-"two passes designated respecg tively by the reference letters L and F, the passfF being the final or finishing pass and thepass L being the nextpreceding pass and the last of the regular series of passes to develop a bar havingfthe design of'the conventional continuous type of rail joint The portions of th'cp'ass L which conform I respectivelyfto the design of the splice designatedbythe'reference numerals 1 and lnember 'andrbase section of-the bar are 2,"and similar reference numerals designate corresponding portions of the final pass F, but itwill be observed Lthat'these portions those of theip'ass F so thatthe splice mam her and base section of the bar as it enters of the pass-L areconsid'erably wider than and 'leaves' -the next to t'ne last pass'L are considerably tanker than the corresp ondin'g parts of thebar as it leaves the final'pa'ss .-*Accordingly, there is a-very consider able reduction or breaking down in the section of the material in its progressive and final development by the pass -'F The neXtto the lastpass L' of the-finishing rolls distributes and prepares the ma: terial for resisting, as well as adapting itself to, the deforming, reducing, and final shaping action of the'passF, and in this connection it may be observed 1that'the'width of.

the section 2 of the pass L is somewhat greater than the-total-thickness' of the base section of'the-rail joint bar where it'forms a seat or support'for the ends of the rails.

The outer .or bottom face of the base section I) of the joint bar is intended to be flat and horizontal throughout. This -is' provided for in both of the passes Land Fby having the corresponding faces 3 ofthe pass sections. 2 flat and uniform throughout, though disposed obliquely or at an angle corresponding to the angular dispositio-nof the base section. b as it is formed in therolls. However, in thefinal pass F a very radical treatment of-the inner or upper face of the base section biof the bar takes placer This action. involves a very great reduction in the thickness of thesaid basesectionat intervals tojproduce a central crownin-gportiona for each joint .bar length, which central crowning portion constitutes a seat and support for the rail ends at the central partofthe joint as clearly shown inlFigs. 4- and. 5 of To accomplish this-.reduction, distribution of the metal, and shaping i in andjoni the upperface of the base section the drawings.

of the bar, one ofthe rolls, A, is provided with a die ring, designatedas' a unit'by the reference numeral 4, andwwhose circum'ference: is formed with a series of relatively long die projections 55, and a-seriesof forming recesses 6- alternating therewith. The effect of this construction is for the die proj ections 5 to break down or reduce the thic-lo.

ness of portions of the base-section of. the bar being rolled, while, the forming recesses 6 only effect a slight reduction in other portions of the base section, leaving such other portions raised or elevated above the depressed. portions and thus producing ;on; one

side or face of the base-section the crowning portions which constitute the central "rail seats :0 of the joint bar lengths. In Fig. 1

of the drawings, the full andjdott'ed lines at 5 one side of the pass section 2 ;r'espectively designate theriction. of the depressed and raisedportionsofthe die ring 4: on the inner or upper face section b of the j oint bar.

In constructing rolls tocar'ry outthe .oper-.

ation above described, the depressions 01''. forming recesses 6,-of one of the rolls are equally spaced around the circumference thereof in such manner that the center of one ofsuch recesses to the center of the next adjacent-zoneis equal to the length of: the. standard rail joint,"inasmuchas joint bars of the length er the standardj oint. 'Hence,- the line of severance of the bar into rail joint lengths necessarily occurs at approximately thec'enter"of'the'said'recesses, or in other words, at approximately equal distances fromit'h'e rail seating projections, and=in this a connection it will; be further observed that since the bar is delivered from the final pass with the base member .openjshears may be. employed for cutting the-bar into rail joint 5 lengths. Also it may be noted that in carrying out the rolling operation of the final pass F, the drag of the material inpassi-ng through theroll-s mayrequi'rea special shaping of the recesses 6,-bu't these-and similare details of: manufacture may obviously be rce sorted towithout affecting .or departing? from the: process of the present invention. I The cross section ofthe rail jointbar as. it
