To all whom it may concern Be it known that I, JOHN H. SNYDER, of the city of Troy, county of Rensselaer, and State of New York, have invented certain new and useful'Improvements in Rolling Railroad- Ohairs and I do hereby declare that the' followingis' a full., clear, and exact description of the saine, reference being hereby had to the accompanying drawings, and 1.o' the letters of reference marked thereon, which said drawings make a part of this specification. A

Like letters represent and refer to likeor corresponding parts. Y

Figures land 2-are perspective views showing railroad-chairs with single and double continuous jaws'or lips to firmly therein, and rolled by means of thev imparolmenfshereinafter described, or byl any; machinery substantially the same. Fig. 1 shows a railroad-chair rolled-with a jaw'or lip thereon, so as to hold one side of the base f of the rail, while on the opposite side thereof there is rolled a flan ge for the purpose of holding that side of the rail. Fig. 2 shows a railroadchair rolled with a continuous jaw or lip upon each side thereof, and projecting inward for the purpose of holding therein each side yof the lbase of said rail. In either case the bottom of the chair projects from and beyond the outside part of said jaws or lips to any required distance for spike-holes, or for lany other shows the machinery for the reductiouand formation' ofv a railroad-chair, having a continuous jaw` or lip on one side thereof for the purpose of holding the base of the rail as aforesaid, and a continuous upward projecting flange, each of hereinafter described. -1' Fig. 4 shows the ma-v chinery for the reduction and: formation Of'a' railroad-.chair having two continuous jaws or lips, one on each side thereof, and more fully described hereinafter. Fig. 5 shows machinery like Fig. v3, dii'ering in oneparticular only,

which is asib1l'ows,to wit x '.lhe collar or tongue o (more fullydescribed hereinafter) in Fig. 3 has a sharp or cutting edge, while in Fig. -4'

it has a., square edge. Either may be used for yth-purpose of making the jawvor lip A, hereinafter more fully described. Figy shows a transverse section of a 'blank bar prepared for.

the purpose of forming a chair with a single lipby means of the machinery hereinafter described, or by means secure` the trackrail which is more fully` by rolling,

Reissue No. 1,316, nasav of any machinery analogous thereto. Fig. 7 shows a transverse sec` tion of a blank bar prepared for the purpose of forming -two jaws 'or lipsfby means of the machinery hereinafter described, or by means of any .machinery analogous thereto. `The nature of my invention and improfvef ments consists in the mode herein described Y of making the continuousjaw or lips of rai l road-chairs by rolling, and thereby forming the same from prepared bars, as'shown at Figs. 6

of suitably-shaped rollers and 7, by means j mounted and running in conjunction with each other, and hereinafter described.

It also consists in the mode of forming the continuous jaws or lips of railroad-chairs Vby rolling into the solid iron of a flange prepared for that purpose; as 'shown at'Figs. 6 and 7,

by means of the machinery herein described, or by any analogous means.

Having thus described the nature of my invention andfjimprovements in rolling railroad-u` chairs, I will here proceed to describe the conf struction and operation of machinery for that purpose, which is as follows, to wit: I form the jaw or lip A of the chair, Figs. 3 and 5, by means of the. rollers D and E, suitably shaped for that purpose, mounted and run together in the usual manner of mounting and runningl together rollers for rolling iron. The

arrows indicate the direction of motion of said rollers. F, Fig 3, represents a section of the frame which holds s'aid rollers in their proper position. G G, Fig. 3, are setscrews by which the upper roller, D, is correctly adjusted to and kept from receding too far from the lower roller E. These said rollers are provided with front f guideplatedliaekguardplates, (not necessary to be shown in the drawings,) correspon'ding in form or sha-pe to the blank or prepared bars,-Fi'gs. 6 and?. I

In rolling railroad-chairs having but one jaw or lip, A, I run 'each bar properly prepared be reversed as to position, D maybe thelower roller and E the upper one, if vfound desirable.

The Vinvention and improvements, however,

asshown at Figs. 6 and 7, between l lthe said rollers D and E, or any equivalents and N, a'shown at I, Figs.3 and the collar ortongue o is enabled`A` 'to do its work. These rollers D and E may `shown at J, Figs. 3 and 5.

would remain the salue.l The said roller E has upon it the said collar or tongue o which said collar or tongue rolls into the solid iron of the said blank bar, prepared as lshown at i Figs. 6 and 7, by means of which the outside -of the said blank bar and to keep it in place while running through between: the said rollers.

The said tongue or collar o may be made of any form desired.

Itv may have a sharp or cutting edge, round or square one, as the case requires, and may be in thickness to corre-A spond to the web of the ba'se of the rail'. After i the-said blank bar has been' passed through the said rollers and grooves P and N, it is then and thereafterfpassed ilatwise between the rollers and grooves U and V therein, as This operation is for Vthe purpose of straightening the base of the chairs, or the jaws or lip thereof, if such be'required, and puts the entire bar thus rolled into proper shape and condition to be sawed into ch airs of the right length ready for punch.- ing thejspike-holes and for' use. The said blank bar may be of any desired length.

In rolling railroad-chairs with two jaws or lips, A A, fromV blanks or bars prepared for that purpose as seen at Fig. 7, the same is passed twice between said rollers D and E, as shownat Fig. 4. 'The blank bar at each vtime l' of passin g said rollers is in an ed gewise position. 'The-said collar or tongue o, in conjunction with Y the said roller D and groove P therein, rolls a recess into the' solid iron for the web of the base of the track-rail, thus and thereby form-- ing the jaws or lips A A. This operation of makingrailroadchairs with a continuous jaw or. lpon each side thereof differs fromthat of making chairs withbut one jaw or lip onlyI by being passed through the said rollers edgewise twice instead of but once, and having Athe grooves in said rollers in shape to correspond thereto. vThe form or shape ofthe saidv collar or tongue 'o'will vary according to any requiredsha-p'e of the recess to be; rolled into the solid iron of the iiau'ge prepared on the blank baraud shown at Figs. 6 and 7 as aforesaid, and the formof the grooves N and P and U and V willalso vary to correspond to and with any desirable change of shape or form in the said jaw or lip.

In rolling railroad-cha1rs,asherein described I avoid the'use of a stationary core, mandrel,'

or former as heretofore requiredin the mannfactureof wrought-iron railroadgcha'irs. 1n

the use of said core, mandrel, or former it is very diiiicult to keepl either in the required place between the rollers used therewith, more especially i'n' making a chair with but one jaw or lip, and they also become rapidly heated and quickly wear down, so' as to leave the chairs too narrow to receive the track-rails and hence, with great expense and delay the.

said core, mandrel, or former is a great obstruction to the introduction of the blank be# tween the drawin glrollers above and below the same, while the blank/is drawn along the saidl core,- mandrel, or former with much diiculty.

By my mode a stronger,"better cheaper, and

more durable railroad-chairf is made thanby any other way or manner of making wroughtiron chairs.

Having thus described my invention and improvements, what I claim', and desire tose- 1. -Making the continuous Jawor lipi'of railand running in conjunctionA with each other,

substantially as herein described and set forth.

2. The forming of continuous jaws vor lips of railroad-chairs by'rolling into the solid iron of the flange on the blank bar, of which the .said lips are composed, and which flange for said jaw or lips is raised upon the blank bar as aforesaid, by means of the said roller herein described and set forth, or by means of any rollers substantially the same.

In testimony whereof I have on this 20th.

day of May, 1862, hereunto set my hand.
