Application led February 2.1, 1925. Serial Q. 10,835.

This invention f relates to railroad rail shaping devices and has special reference to novel means for `formingnotches in the lower opposed ycorners-ot thebulb of `a railroad rail upon which portable superstructures are supported,v such torv example as dock cranes, or the like, and which are provided with rail Vclampsor holding devices, notched for cooperation with such rails. e Theprinci'pal object is to produce a practical andsimple 'device forthe economical andu-niform'- shaping yof such a rail, and one that may be readily adj-usted so as t0 be apvpli'oable'to various sized rails.

Other 4robjects and advantages' of the invention will appear in the further description thereof. f

` Referring now 'to the laccompanying draw ings, forming part ot this application, and in which-like reference characters indicate like parts): Y

Figure 1 is bodimentot my improved rail shaper vas ap Pli'edjt'ofa railroad rail; v

Figure 2 is a top plan view; and" Y -Figrure 3 isa central transverse section fon the'line tie-3, Figure 2.

1 represents an ordinarysteel railroad rail, and2 is'the body portion ofthe Shaper 3o carriage which issuper'unposed upon .the rail; this .carriage comprising an elongated narrow metal member supported at either end upon a, roller 3., the journals of which are shown atl 4, within laterally Aextending, brack;

:35 ets-5, upon either side of the lower corner of the member 2; this being to permit of as wide `a tread roller 3fas possible, the same being preferably approximately the same `width vas the body member 2.;

the carriage are upwardlyv extending brackets t.6', they being somewhat triangular in sha ve from an end view of the carriage and havinfrin the uppermost extremity the shaft 7, Whittle in their lateral extremities Aare jour` nalled two `like shafts Sand 9, `The shaft 7 is that which transmits power to theshaper from a source offsupiply which-may either be manual or byfmeans `ot anyform of motor either directly connected wor otherwise, though I havesimply shown a crank 10'as representing such adaptation. This crank isV shown as applied directly to the large 'disc @1V-gear 11,- whch,as is obvious, may beso a side elevationV of one gem-V Upon either end of the body portion 2 of uponthe shaftS' and the other upon theV constructed as to receive action p firombother forums-of power thanthe crank. y0n the oppos1teend of the shaft ,7 is -mounted a small spur gear 12 which` meshes with fthey larger gearl keyed to ltheshatt 8 externally of the vbracket 6, the saine being for the rotation of said shaft as well 'fas the shaft 9, the cooperative action of which will be described ater.-

Slightly to one-side of 'the middle lofthe l carri-age body 2 are rigidly attached thereto two upright spaced members 14, .the shaft 7 These l.members 14 act asvguideways for the pivotally vunited

members

15 and 16 which are so .united centrally kas at 1 7, and their pivotal pin y'is -extended- `suiiciently to be .guided within the `s lot. 18 in the lmembers 14.

rotatively passing through said members.

There are two members Lor links 16, one upon either side of Vthe member `15,-andtl1e links 16 are pivotally connected;as.at 19 tolthe upper endeof the cradle 20, while one end of the member 15 is pivotally united as at 21 to the cradle 22. The opposite `endvof jthe i e member 115 is arched upwardly, overreaching the pivotal connection'lQ ofthe links 1 6v and cradle 2O and extends outboard of same as a manipulating -handlje, indicated yat 23.-y To this handle, just outwardly of the pivotal con-A necti'on 19 ispivotally supported as at`l21e (the depending link 25 carrying an externally screwjthreaded rod l:2 6 Vpassing through the slotted lug27 projecting, from thefupper end ofthe cradle 20, and said rod beingiprovided with the adjusting j nut 28 provides conf venient mea-ns for raising and lowering they pivotal point 17, thus Vdrawing together or' the upper ends .of vthe cradles 20 y separating and 22. Y

These cra les arey pivotally mounted, one

shaft 19,. and the upper extremities of Vthe cradles f are of single wide constructionhavrespectiveshafts, wh-ile their lower ends com'- `prisetwo spaced leg-like members 29 lonl the 'cradlef20 and 3 0 on the cradle 22.

se 'l i-ng'a bearing the full width thereof on their i ico double train of gears, 'one uponv eithersideof each cradle, such gears being numbered 34, 35, 36 and '37, the trains or sets being identical andare used in multiple in this manner to provide ystability and 4 evenness of driving power. The gears 37 on the shaft 8 and like gears onthe shaft 9 are madeof bulb of the rail l when the cutters 33 arev the proper diameter to intermesh so that lone pair drives the other at a uniform rate of speed, they both deriving their power from the shaft 8. t Y A Upon what I choose to call the rearmost end of each shaft 3lV and 32 is keyed aA worm 38 which is of a suitable diameter to snugly mesh within the nished notches 39 formed upon the lower corners ofthe in operating position against thev bulb of the rail, and vwhich position as is obvious 1s determined by the linked connection just described of the upper ends of the cradles 2O and 22. Now it will be observed that if they large gear 13 keyed tothe shaft 8 imparts a clockwise rotation to lthe shaft 8 as viewed vfrom the front of the machine the same will rotate the cutter or tap 33 on the shaft 31 in an anti-clockwise' direction, and the Y substantially Yso in the front end of the tap t Figure l of the drawings;

and finished full depth in the rear,kv each tooth will cut its respective depth as the device is advanced by the` worms 38', they rotating as is obvious at the same speed as the taps and in the finished notches made byl said taps. 'j Y Thetaps 33 diler from an ordinary thread formingA tap as used in making cuts or the like in that the clearance ways or channels'longitudinally of the tap are slightly spiral 'in form as'clearly indicated in This is done as is` obvious for the purpose of avoiding chatter and kjumping of the VtapsV by the continuityv of the cutting process due to the spiral form of the clearance channels.

There is illustrated at 40 a transverse reinforcing bar'or member, it being Vmounted securely upon the upper edge of the body portion 2 of the carriages, and through the opposite ends of which the shafts 8 and Y 9 extend, forming an additional journal and bearing for same. Intermediate of this auX- iliary bearing and the bracket'on'the front end of the carriage is-swingingly journalled as in the depending bracket 4l from the shaft-8 a vertically disposed cutter shaft 42,

` carrying upon its upper 'end and just beneath the: shaft 8 a miter gear 43vmeshing with the similar gear 44 keyed to the Vshaft k8, and 'upon its lower end-a tapered'cutter headv 45. rlhs cutter head is for planing the side edge of the bulb ofthe rail as the shaper is passed therealong. Upon the shaft 9 is an identical cutter head andthe two brackets 4i of whiclnarefheld together as by the' through bolt 46 having 'adjusting nuts 47 thereupon externally of each bracket, so that the adjustment of the brackets laterally may be accomplished to a'nicety and resulting in 'a uniform sizing of the bulb of the rail prior to being operated upon by the notch forming tapsyand Vit is also obvious that the lower corners of the bulb of the rail must be chambered by hand orotherwise for the initialstartingof' the device. l Y

`While I have shown the .bolt 46 and nuts 47' as a siinpleimeans of adjustmentforthe bracket 4l it is evident that the bolts may y be dispensed withand a link mechanism identical with that for similarly adjusting the taps b e employed above the brackets 41.

J ust inwardly of thebracket 6 ateither end of theV shaper is a pair of depending laterally adjustable arms 48, one suspended from each .ofthe

shafts

8 and 9,1and in the lower end of the each of these arms is rotatably mounted a guiding roller 49, it khaving an extending'iange 50 about the ylower l end of same, ,the latter being engageablebeneath thel lower corner of the bulb of the against the side of the bulb, they being for the proper guiding and supporting ofthe shaper upon the rail.. Furthermore each pair of the arms-48 are made laterally ad- .rail and the thread thereof i engageableV justable by a bolt 5l and suitable nutsf52 similar tothe manner in which the depending brackets 4l are made adjustable.

From the foregoing itfis apparent that I have devised an exceedingly sim le and compact shaper for the forming of a series vof notches uponjtho lower outer corners of the bulb of a rail inpreparing .theV same for use in connection with the rail clamps equipped vfor such engagement; such a Y clamp being fully disclosed in Vmy copending application Sen'No. 730,936.' While IV have illustrated oneV practical embodiment of the invention such as has already been 'employed itis apparent that various ymodio fications may be resorted to without departing from ythe scope of the following claim s, f

it being understood that the device may be used as a planer only 1n restorlnga` deformed rail to uniform size,1or thatany oneV or more of the four corners ofthe bulb .of l

the rail may be shaped, as desired.
