RAIL-CHAIR.

Application lcd April 28, 1913.

To all whom t may concern Be it known that l, AUGUs'r G. LIEB- MANN, citizen of the United States, residing at Butte, in the county of Silverbow and State of Montana, have invented certain new and useful Improvements in Rail- Chairs, of which the following is a specification.

This invention relates to railway track appliance and particularly to rail chairs, and means for holding the rail in place therein and adjusting the rail.

When rails are held to the ties merely by spikes engaging the base flanges of the rail, the thrust incident to the passage of a train tends constantly to loosen or withdraw the spikes. The vertical thrust of the rolling stock tends to force the rail into the tie crushing and breaking the fibers of the same. The lateral thrust tends to shear the spikes or loosen them, and the tipping thrust tends to tip the rails upon one side edge of the base flange and raise the other side edge, thus withdrawing the spikes. As a consequence, there is constant necessity of redriving and renewing spikes and ties. Furthermore, where spikes are used any depression or elevation of one portion of a rail or section of a track under, for instance, the action of frost or thaw, tends to cause either a withdrawal of the spikes, or the base flange of the rail will shear if the spikes can not be withdrawn.

The primary object of the present invention is the provision of a very simple form of rail chair in which the rail is to be seated which may be readily formed by rolling and pressing, and in which to this end the body of the chair is made from a deformed I- beam section.

rfhe further object is to so form a chair that the rail will be fully supported against vertical or lateral thrust or any tipping action. The chair with oppositely disposed abutments between which the rail is seated permits the use of rail clamping wedges between the abutments and the brace or lining plates of the rail, these rail clamping wedges permitting the rail to be laterally adjusted between said abutments so that' the rails of the track may be brought to gage and readily kept in gage.

The still further object is to so form a chair that the rail may be readily adjusted Specification of Letters Patent.

vertically by means of shims and then held rigidly in its adjusted position.

Another obj ect is to so form the chair that the clamping wedges whereby the rail is held shall be prevented from any vertical displacement.

Another object is to provide a type of chair and rail clamping means particularly adapted for use on southern lines with well drained sub-grade and rock ballast, and for either freight or passenger trafhc.

Other objects will appear in the course of the following description.

The invention is illustrated in the accompanying drawings wherein:

Figure l is a perspective of a tie and rail and the improved rail chair applied thereto; F ig. 2 is a plan view partly in section of the construction shown in Fig. l; Fig. 3 is a vertical sectional view on the line 2)-3 of Fig. 2; Fig. l is a transverse section of the structural member from which the chair is made showing in dotted lines the way that the member is pressed in order to form the complete chair.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

Referring to these drawings, A designates a tie and B the rail. rlhe rail B may be of any type but as shown is of a standard type. The improved chair comprises a bed plate 2 having a width preferably that of the tie and resting firmly on the upper face thereof. Extending transversely across the bed plate and parallel to the direction of the rail are the abutments 3 which are spaced from each other a distance slightly greater than the width of the rail base. These abutments extend vertically to a height nearly equal to the under face of the head of the rail` and are then bent inwardly at right angles to form overhanging lips 4L. The bed plate with its abutments 3 is preferably formed from an I-beam section. The metal of the plate is first rolled in the form of an I-beam and then the flanges of the I-beam on one side are bent outwardly at right angles to the flanges on the opposite side in the manner illustrated in Fig. 4, the dotted lines showing the manner in which the flanges are bent so as to form a bed plate. It will be seen that this bed plate may be easily formed by rolling and'pressing. and is an important feature in the practical construction of the chair. y

Disposed on each side againstthe web of the rail are brace or lining plates 5. Each of these plates has an inner face adapted-to lit the web of the rail and upper and lower fianges each having a beveled face adapted to fit the beveled face of the base and the under face of the head of the rail."

Disposed between the abutments 3 and the' lining plates-"5` are the' 'wooden wedges '6.

These wedges are' longitudinally tapered upon their outerf erJv innerA facesfand-I upon their' lower or upper faces andsnugly nt inI the space-"- deiined by the abutments,` the base flange of the rail and the l' outer faces of the liningplates Eachfwedge isfrabbeted upon its lciwer 'facey asatl'soI` as to t overy the lower yflange of the" corresponding cheaply made b'ut is well adapted 'i for usel on lines in f climates where the line is well drained. It will be obvious; however, that these wedges' may always be kept tight by` th'e track* walker withy very little trouble. It" often occurs'I that theV railv mustl be adjusted vertically in order to keep the line of track level as where 'one portionoff the track has beenlifted'by frost and itis necessary to adjust `the adjacent portions' of 'the` track. This 'may be readily* a'cc'omplislied'by' looseningl the" wedge's 6 andthen' inserting' a shim 9 vbetween the base of the rail aridi they raill After'thefshim is driven in* place',- the wedges 6* are again' seatI on the' bedplate.

forced inwaidluntilithe" lining plates 5 se curely clamptlfe rail: Itz is obvious thatby withdrawing one ofthe wedges and' driving the' opposite wedge/6 in farther thatthe' rail may be laterally'shiftedwith relationto the base plate and thus it is -"avery easyl matter for the track to be kept in gage'at all times whereas-where spikes' areused, it is a very di'licultima'tter to lkeep the trac'lrj in gage:-

It will' be particularly notedf fromv Figs'.

2 'andlS that thelining plates 5 areshorter than the `wedges and as a` consequence' when the wedges are forced inthelining plates will bite'Vv into the" wedges; thus preventing shifting' of the accidental longitudinal wedges unless theyl are positively 'drivenfou'tp It will also "benoted that the abutments' 3,

beingparallel to the rail and to each other have a tendency to stiffen the bed plate at points on each side of the rail where the stift enin'g is most desired,` andfurther' that any slight buckling downwardly ofthe bed-plate under rail pressure will cause said abutments to curve or bend slightly inward toward the rail, and thus press the wedges into the lining plates and hold said'wedges in a xedposition;

Particular attention may be calledin connection with my improved ra-ilichair to the oiiicial report of the Bloclr'Sig'nal and Train Qontrol Board of; the Interstate vCommerce Gommissiong-vthis report being dated J une 29, 1912, wherein certain requirements'are laid `down for rail supports andwherein the board"says:'LAQi fundamental defect inde-` sign which is most apparent is the failureY to're'alize and appreciate the overturning movementf du'e to l the wheel flange' pressure against'the head oftherail.IVA ltis not sufficient that the tie should support the'vertical loads `and" resist'` directly horizontal thrusts and thetendency of the trackl to more later! allyfand longitudinally, but theo verturning movement must be'l'r'esisted. the tie`n1'ay properly* support the stresses transmitted to itt by the rail,l asu'itable fasteni/iig offthe rails to" heties is most essential Further the reportstates that""under conditions existingina large preportionof the'railr'oads in thiscountry the means of adjustment of rail=to`tie must be su'chas to admit of blocking up or4^ shimming.7 The board further says that adequate' means should be' provided for shimining or tor widenii'igfgage andk this-means should not involve lost motion and change of adjust'- ment. It ispointedouttliat the improved railchair, as heretofore described, conforms to allof the requirements referred to in this report and at the same time the fastenings are not of a complicated'nature andfthat-the chairs may be made relatively i cheap. i
