To all whom t may concern.'

Be it known that I, AUGUST G. LIEBMANN,

, a citizen ofthe United States, .residin at his invention relates to pliances and more particularly to rail chai-rs. The object of the invelitlolgz orally stated, is to provide means ing rails under all conditions of for use with rany type of 'tis that considered most economical .from an eligiering point of view. i, j

At present, inferior grades of wood ties,

previously' subjected to treatment, are. ,the

most economie form of tiesI and, as it is in'iperativethat such tiesbeltreated to resist decay, the present invention aims to; pr'o vide a. composite adjustable chair having an eicient' fastening to obviate mechanical wear upon such treated oruntreated ties.

The essential factors in a composite adjustable' rail chair are as follows:

First, the elimination of mechanical wear.

Second, eiciency in maintenance.

Third, the factor of resultant economy.

Fourth, the factor of safety.

Recognizing the need of a rail chair embodying, in a unitary structure, these essential factors, the invention comprehends the elimination of mechanical wear by providing means for track gage variations on curves and tangente and rail surface variations in shimining without disturbance of ythe primaryV fastenings; for' yan -increased area of plate support on the tie to prevent cutting and Vcrushing of said tie; for supporting the bed plate per ae to prevent bucling and curling` of the ends of the plate;

for ermanently supporting the bed plate on t e tie to revent abrasion; and for eliminating respiking and 4consequent splittii'i'lg of the tie..V

heinvention further comprehends an increased eiciency in maintenance by providfing means for expediting rail renewals of -jo1ned"rails;. for preventing the ties from ffskewingrifor adapting the chair. to all conditions of track; for permitting the use of the chair ongnew 4or old ties, and for-pre- -venting lostinotion and change of adjust-4 ment.

'the appended claims.

Further to increase the-factor of economy i further to insure 'the factor of safety by compensating for the recoil of the rails nder stress; b supporting the rails against` lateral, vertica and tipping thrusts; by the prevention of broken rails in a permanent` rail `seat su port; by holding the rails secure in shiiiime positions; and by increasing the holding power of the plate fastenings t0 prevent 'rail displacements.

Further objects and advantages will appear in the following description, it being Vunderstood'that .various changes in form,

tion may be resorted to within the scope of In the drawings:

vCorresponding land like parts are referred to in the followin description and indicated in all the views o the drawings by the same reference characters.

Referring to the drawings,'A represents a rail having a standard cross section, and B a tie supporting the ra. l. Mounted upon the cross tie B, is a bed plate 5 referably a rolled shape, although. the p ate may be cast or otherwise formed, if desired. The bed plate 5 is substantially rectangular in shape, as shown, and preferably extends the entire width of the u per surface of the tie, the opposite longitu mal ed es of the plate being bent downwardly to orm depending fianges 6 which not only serve to reinforce the plate, but by contact with the adjacent sides edges of the tie assist in preventing displacement of the plate on the tie. The extended area of the bed plate support serves to prevent uttin and crushin of inferior wood ties, while the depen ing flanges 6, in conjunction with the clamping members, hereinafter referred to, prevent Athe bed plate from buckling and curling at its ends and also prevent splitting of the cross tie. y Y.

Projecting upwardly from the bed plate `5 at'the o osite ends thereof, and preferably forme integral therewith, are abutments 7, these abutments being hollow and having their exterior walls preferably of octagonal shape to present a plurality of flat faces 8. Openings 9 are formed in the bed plate, one in alinement with the socket of each abutment for the reception of screw spikes 10, said spikes constitutingv the rimary fasteningdevices for securing the ed plate to 'the-:cross 'tie and having their u per portions provided with machine threa s 11 and their lower portions formed with screw threads 12 for engagement with the tie. Shoulders 13 are formed on the screw spikes at the junction of the threads, the lower face of each shoulder being convex and adapted to rest on a correspondingly concaved seat 14 formed in the uppersurface of the bed late. spike is pre erably forme with an angular head 1-5 so as to permit the screw spikes to be conveniently grasped by a wrench or other suitable tool.

The u per end of each Mounted on the abutments 7, are frustoagainst rotation on the abutments after said i clamping members have been actuated to adjust the rail vertically or laterally with respect to thebed plate. The lower face of each rail clamping member is provided with an eccentric portion 18 adapted to bear against the adjacent longitudinal edge of the base flange of the rail A for shifting the rail laterally with respect to the bed plate when the clampin members are ad- )usted with respect to t e abutments, the eccentric portion of each clamping member defining a circumferential clamping lip 19 for contact with the upper face of the base fiange of said rail.

It will here be noted that the frusto-A conical rail clamping members are disposed concentric with the abutments, while the portions 18 are disposed leccentric to said abutments. lVith such a construction, it will be readily seen that b clamping members around t ie abutments, the raily may be adjusted laterally withl respect to its seat for gage. It will, of course, be understood that in order to adjust the clamping members around the abutments, said clamping members must first be disengaged from the abutments, that is to say, they must be elevated above the upper ends of the abutments and then turned until the desired fiat faces of the abutments and clamping members register after which the clamping members are again positioned on the abutments and secured in adjusted posi tion by means of the cap screws.

Threaded on the screw spikes or primary fastening devices, are secondary fastening devices, preferably in the form of screw caps 20, each screw ca n being provided with an interiorly threade depending cylindrical portion 21 for engagement with the machine threads on the adjacent spike and having a polygonal shaped head and a circumferential Harige 22 adapted to bear against the upper flat face of the adjacent rail clamplng member so that when the screw caps are adjusted home, the flanges 22 will bear against the members 16 and clamfp the ase a latter in engagement' with the b nge of the rail.

moving the It will here be noted that the ripper face of each clampin member 16 exten s a slight distance above t e upper surface of the adlso 'i lals i so

jacent abutment so as to cause the llangeQQ to bear directl on the rail clamping member and througli the medium of said member transmit a clampin action to the base flange 5 of the rail. It wi l also be noted that the y flange 22,'by contact with the upper face of the clamping member, compensates for recoil ofthe rail under stress. Should the screw cap 20, for any reason, become loose, the. rail clamping member-will have a slight vertical movement on the adacent abutment and thus revent fracture o the base flange of the rad. l n

. As the clampin members are substan- 16 tially frusto-conica in shape, the outer faces of said clamping members lwill form, in

effect, skidways andthus expedite rail renewals with joined rails,- it being merely necessary to remove one of the clamping members 16 and then move the line of joine rails laterally from engagement with the li ofthe other clamping `member when lsai joined rails may be readily removed, the inclined faces of the clampin membersform- :will further be noted that the screw caps 20 not only serve to clamp the members 16 in engagement with the base flange of a rail, but also serve to house and protect the screw spikes or 'rimary fastenings and resist the action of t ewheels of derailed cars so as to prevent injury to the primary fasteningdevices. The rail clamplng members are pref erably disposed in staggered relation on the bed' late and are so constructed as to allow for ongitudinal expansion and contraction of the rails. The primary fastening devices in conjunction with the flanges 6 o the bed plate, serveto prevent ballast from working under the bed plate and destro ing-'the be plate support. The rimary astening devices also revent bucliling or curling of the ends of sa1d bed plate.'

In orderto adjust the rail laterally on'the remove the screw caps 20 andpositionone of the rail clamping members on the adjacent abutment with the large portion of the eccentric bearin against the base flange of theI railon one si e thereof, and with the short ortion of the eccentric of the other clamplng member bearingy against nthe base flange of the rail on the other side of said rail, after which the screw caps are threaded on the screw s ikes and adjusted home, which clamps t e members 16 in engagement with the base flange of the rail and eifectually prevents accidental displacement of said rail. It will be understood that by moving the rail clamping members 16 to di'erent positions of adjustment, around the .abutments, the rail may be shifted laterally in j either direction for gage, as re uired. In

` order to adjust the rail vertical y for sur- 05 face, the screw caps are rotated to elevate 1in th1s application is of minimum weight ing, in effect, skidways, as efore stated. It' 4 interchangeablel and may be moved'in either direction to different positions around the n l bed plate for "gage, it is 'merely necessary to 1n Figs. 8 and 11 ofthe drawings, there is the same and a shim 23 placed beneath-the A rail, after which the screw caps are. tight` ened, asbest shown in Figai ofthe drawsVA ings. I f desired, the shim 23 may extend beneath theadjacent rail clamping members 'I0 so that when the screw caps are tightened, f said rail clamping members will prevent ac-4 cidental displacement of the shim. Attention is here called tothe fact that by reason of the large radiusof the eccentric portions 18 of the rail clamping membersan extended bearin surface is presented to the i n base flange oft e rail,4 thus preventing the ties from skewin ,and further inasmuch vas the members 16 ear against thefiiange of, the raily at "diagonally opposite points, said members will assist in supporting the rail against vertical, lateraland ti ping thrust. The particular form of fastening disclosed B5 and of few partsand is so constructed as to prevent rattling, due to wear of the parts or, lost motion with consequent change of adjustment. The rail clamping membersare 1 abutments to eilect the adjustment of the rail for gage. 4Wheny the chair is `madeof a casting, a copper content will preferably be added to the material so as to cause the fas- `Sli tening to resist rust and thus prolong `the life thereof in saline soils and withstand the drippings from,.refrigerator.cars.

In Fig. 6 of thV drawings, the rail chair is a shown in4 connection with joined rails, the construction and operation of the device being otherwise the same as that shown in Fig. 1 of the drawings, with the exception that the lips19 of the rail clampin members engage angle bars 24, instead of aring directly on the base flange of the rail and in that the eccentrics 18 are of greater depth to permit the lips 19 to bear lagainst. saidl an le bars. j i

further modification is illustrated in Fig. 7 of the drawings, in which the abutments', instead of being rolled or cast with'y the body of the bed plate, are formed sepal rately and seated in suitable openings 25 formed in said bed plate. In` this form of the device, the abutments 7 are providedy with laterally extending circumferentialv 1 Ilanges 26 which fit in countersunkportions y f '27 in the upper surface ofthe bed plate so es to prevent accidental displacement of the abutments and at the same time present a y j smooth surface fory the rail yclampmgfmem` ber. It will ofcourse be understood thatthe C abutments 7 may be secured `with-in the openings 25 in any` suitable manner. l

The device shownin. Fig. l is particularly adapted for attachment to new ties. yThe chair, however, may be applied `with equally results to old or spike killed ties, and

ico f los l y `illustrated avstructure for this purpose.

When the chair is used on old or spike killed ties, the bed plate is preferably formed with a plurality of square openings 28 and 29, the openings 29 being adapted to receive screw bolts 30, the heads of which extend through the openings 29 and are preferably j countersunk in the upper surface of the tie.

Ordinary spikes are preferablyA driven in the openings 28 for the purpose of holding the chair securely in position on the tie. As the openings 28 and 29 will bes aced from the spike killed portion of an,ol)d tie, it is obvious that a. fresh or unmutilated area of the tie will be presented for the driving of vthevv ordinary spikes, when using thistype of the invention, as ybest' shown inf11 of.

theidrawings.

Where the fastening is used on curves, a brace 31 is preferably employed, the inner endrof said brace being provided with a head v32 for contact with the lower face of the head of the rail and the base flange thereof, respectively, and the outer end of the brace being -interposed between the upper face of the rail clamping member and the lower face of the flange of the screw cap or secondary fastening. In order to cause the brace to bearj-,against the rail and prevent displacementi of the brace, when the rail is adjusted laterally for gage, the lower face of the flange-of the screw cap 4is preferably formed with one orv more ribs or corrugations 33 adapted to enter corresponding grooves 34 formed in the upper face of the brace, there being a slot 35 formed in the brace adapted to receive the cylindrical portion of the screw cap and permit adjustment of the brace to accommodate the rail. This brace 31, as

will be understood, prevents tipping thrust.

of the rail on curves.

In Fig. 12 of the drawings, the improved fastening is shown in connection with a conventional form of frog, .while in Figs. 13 'and 14, the fastening is-shown for clampingV a stock and guard rail, respectively. The

fastening device may be employed with ually od results for use; in connection wlth switch points and in Fig. 15 of the drawings, the fastening is shown supported on a base plate and engaging the stock rail adjacent a switch point.

While the abutments and sockets of the rail clampingmembers are shown as being of octagonal formation,y it will of course be understood that they may be square, hexagonal or ofany other angular shape or that other means may be employed for preventing rotation of the clamplng members on the abutments after adjustment for gage, without departing from the spirit of the inventlon.

From' the foregoing description, it will be seen that the improved chair provides for gage variations on curves and tangents; for

the restoration of gage without respiking; and for rail surface variations, low joints,-

kinks, shimming and the like, without vrespiking. The chair and fastener forming a part thereof is so constructed 'that it will effectually eliminate mechanical wear to cross ties, and consequently prolong the life of treated or untreated ties by providing for lateral v and vertical adjusting of the rail for curves o r tangents without the necessity of disturb# ing the primary fastening devices or resplk-y 'ing or shifting the bed plate ofthe chair on the tie to effect such adjustment.
