' ToaZZffwh'om t may concern: Y

Y Be it knownfthat I, CHARLESE.' KLELLDY, ya citizen of the United States, residing at `Superior-,in ,the county of vDouglasand l State 'of Wisconsin, havelinvented certain new Vand 4usefull Improvements inv Raill Clamps, of which `the following isa specification, reference being had therein to the accompanyingfdrawing.

This :invention relates to'rail clamps and has particular reference' toma clamp or holding device for traveling cranes or other large superstructures such jas .coal dock derricks, bridges,` or 'the like, adjustably umounted v upon railroad rails. The principafobjectof -the'inyention' is to provide-a simple vand efficientv formv of rail 'cla-mp vor securingv means forsuch "struc- "tures l A' v L Another object is to providenmeans 'whereby suchv adevice when in clamped engagement with lthe. rail' isl positively secured f against longitudinal movement thereupon.'

` Still another Objectis to provide simple ,fmeansffor both applying andi'r'eleasing the clamp, and'one that whenreleased laterally' from the rail will' alfsobe' raised vertically -freeing same. i 'l i ,l

Other lobjects andadvantages will appear in the further description ofthe invention.A

Referring now to the accompanyingdrawings forming partof this application and f in which like reference characters indicate like parts:V v ff'- Figure 1 Lis an eleva-tion lof one''embodiment of the improved rail clamp as' yiewed longitudinally ofthe-rail; l v Figure 2 is a side elevation of Figure '1; Figure 3 is a view similar to Figure 1,)but

reduced in scale, illustrating a modified a'r.- i rangement 'of .the clamping member;

Figure 4; is a side elevation of Figure 3 v Figure 5 is a perspective view of improved railconstruction; and Y Figure 6 is a perspective view of'one vof the gripping jaws of theclamping member.

1 represents the improved form of rail upon which the superstructure, as indicated at 2, is carrled, there being shown, 1n Figures 3 and 4, common wheel construction for such purpose, the particular arrangement ofV which does not constitute part of my pres ent invention. y Y

f represents a horizontally disposed shaft, -which, fin the preferred arrangement lof the clamping member, is disposed parallel with anddirectly above the/'rail 1,' and @represents that portionof the superstructure in which the shaft is mounted. From this 'shaft depend 'the twopendulum likefmembers 'and 6, their upper fends being altermember 75 are identical o'peningsS. Through these openingsextend thev links or Varms '9,

k10 and vl1, they' 'being pi'votally mounted nately recessed andengaged upon the shaft"l` vas clearly shown in vFigure 2, so that each Lare a plurality of vertically elongated rec-*v tangularly shaped openings 7, Vwhile in the upon the shaft 12 in the knuckle 13y of the'VV vmember 5', and at -their opposite endsare Vmounted upon the shaft 14 outboard of the lconvex portion 15- ofthe member 6. The arms 9 and 11 lextend considerably beyond lthe'V shaft 1a-and are carried by the short shaft 35, which extendsthrough their eX- treme ends,v1and pivota-lly4 engaged within the. lower extremities 'of thejd'ependin'g oper'- atin'g members 16., Thusf'when the operating members 16 are raised and'hlowered,"

the shaft willlalso'be raised and lowered, carrying with itthe arms 9 and. "11 directly, 'and the armV l() indirectly. as' the latter is l mounted only uponv the shaft 111, it prefer-. v.ably not *beingfdirectly connected to the shaft 35.`

''Mounted upon the shaft Mare four spaced rollers 17 they bearing against theconcaved 'surface of the memberI 6, and roll freely thereupon when the shaft 14', is raised or Alowered for forming as nearly as possible a non-frictional` engagement with the surface of Vsaid member 6; Tovone end of theshaft 14 is latt'ached'the' link or pitman 18 which extendsy upwardly' 'to' the crankarm 19Qcarried upon; the shaft 3, said pitman and crank arm being pivotallyf united` vasat 20.` vThe crankarm 19l is securely fixed' to the shaft 3 so that when the former is raised or lowered it will rotate the latter, and in the bearing for the shaft 3 is mounted an eccentric sleeve 21, the same being rigidly attached to 105' the shaft so as to rotate with the latter,

there being one of such eccentric .sleevesv is raised by manipulation ofthe operating levers 1.6 it will rotate the shaft Sand therevbyslightlyr raise same, lifting the clamping members and` 6, freeing same from the top ofvr the rail simultaneously with the later-al f Vfreeing of the jaw portions of the clamping members 5 and 6. v A

The jaw portions of the clamping memfbers 5-,and 6,-arefrecessed as yat 22to receive ytheremovable jaws r23, these latter'loeingv .of

vharder material than 'that of )which the .members 5 vand 6 are `composed and which may be renewed or removedffor repair from timel to time without the expenseand time incident to further dismantling ofthe clamp.

y. These removable jawwmembers 23 fare adeftobe heldsnugly in place, and maybe proquatelylflanged at either end as -at '24 so as y.wvided withl-temporary tap screws or ,pins

'as `at 25. TheY lower inwardly projecting 'corner 26 off each -jawy 23 is ycorrugated ,or

notched as at 27, ysaid notches registering 1 with like' notches-28m the lower corners of :the bulb of the rail 1;, thisbeing considered a novelI formY orfshapingofrail to :prevent f longitudinal movement ofva clamp attached -.thereto,V it positively insuring against the v movementof the clamp evenv when slightly insecurely clamped thereupon. Y

i However, from the .abovedescriptiomit isapparent 'that by the depressing of the levers 9, 10 and 11 to anywhere near. their .ultimate clampingA position, the pressure ofsaid membersgt'oo'rjromll .the frail. l

Q the jaws ofthemembers andrG :is greatly augmented andmade positive VYby ltherollers verse the rail l, the object being to illustrate .how such a` modification Vmay be accom- V,the-member 6. v f v In lFigures Sand 4 I have illustrated the -dulum-r clam ing members pivotally `carried 177 traversing the inclined convex-surface ot clamp suspending shaftf'as being transplished without departing from lthe spirit lever indicatedat 29 which is controlled by thebell-,crankv lever 30, the same being for spondto .the clamping members-5. and 6 Ain the other views. In Figure 3 I havefshown -a' bracing memberv33 pivotally mounted `asV at 34; in the superstructure 2 for bracing the rail clamp longitudinally ot the rail.

From the foregoing it isevident that I "have provided-an exceedingly simple and signature.

reiiicient. rail vclampingmeans which wheny applied tothe-rail even 1inv an slight degree will insure positive anchorage of the superstructure to whichit is .attached,. ,and,`one that if not positively adjusted 'ftojthe contralry will remain securelyattachedo the rai I claim and desire to secure by Letters Pat- 'ent, is: ,n Y n e 1.
