Tb ciZZ wig-m ifmdy 00mm} Be it known that I, HARRY SlMrnns, a citizen of the United States, residing at Van, in the county of Venango and State of 7 Pennsylvania, have lnvented certain new a and useful Improvements in the Arrange=' ment of Winch Elements,'of which the following is a specification.

his inventionrelates to anarrangement of winch elements, and more'particularly to the disposition of the elements of a hoist machine in whlch 1t is desired to'secure a maximum efiective'windingjdrum capacity .to aggivenvwidthrof space available for the The particular adapta- V tionselected for-the purpose of illustration is a hoist attachment fora tractor, in which I the available space is that defined at the rear of the machine by the tractive wheels. "'-The winch as a whole.

winding drum in such an attachment must have sufficient width. to accommodate the -necessary length of wound-cable without V associating With'a drum-carried drive gearinterfering with i the coupling and operation of a tractor drag bar, particular reference being had to the F ordson tractor. Such an attachment comprises a framework -upon' which is supported the active elements'of the winch, and this framework is attached to the differential housing .of the tractor and to the drag bar casing. However,'it willbeunderstood that the invention may be em ployed in any sltuation inwhich economyfof 1 space is a fundamental requirement.

7 The object, of the invention'is the produc tion of a hoist attachment whichwill occupya minimum; of space and have 'armaximum of winding capacity; A. further object is the arrangement. of hoist. elements upon :a supporting framework in' such a manner that a minimum width of framework-can :be used with awinding drum of large capacity.--.T

A further object of the invention'is the Y disposition of element-sin a chine, which will distributethe driving hoisting' niastrain'npon the parts bestcapa'blexof sustaining them.

It will n ers de-5a'aaiaaa eaioa may be 'va ried in its details of construction 1 and that the specific embodiment" illustrated I Tand' described -herein is ;only-"indicative thereof; the 'saidspecific embodiment, how'- ever, is one which has been found to-be f f practical in its construction andoperation':

The winch-is supported inany sultahle framework 10, there being pro'vjided' 'beara drive shaft and a shift=rod,"respectively,-

. which are mounted in: substantial paralle1 ism. The drivenshaft carries -the1w1nd1ng drum 14, the drive shaft carries the-drive sprocket l5 and the drive pinionlihfy hile the' h ft rod'carriesthe ,y k l7 dw takenupon the line if 'ings 1'1, 12 and 13 thereon for a driven shaft,

tuated by the lever 18. The numerals 19, and 21 have been chosen to designate, re spectively, the driven shaft, drive shaft and shift rod. v

These and other parts of the hoist will now be specifically described and their individual functions pointed out, after which a recital of their conjoint operation will be given. I

I The hoist is shown as embodied 1n an attachment for a tractor but its use is not so drum with a removable partition 31, such limit-ed; there is one result obtained in the tractor to which special attention may be called. Between the rear or tractive wheels 22, 22, of a motor vehicle of the F ordson type is the differential housing, below which is a draw bar casing to which the lower member 24 of the frame 10 is secured. WVhen the tractor isnsed for hauling another implement, adrag bar is attached to the eye plate 25. It will be appreciated therefore that in order to prof-ride a facility of-attachment of this drag bar, it is neces sary that therablc wound upon the drum let. shall not exceed a certain thickness of wind and hence the desirability of providing a winch having a maximum of drum width in a given width of available space for the hoist machinery as a whole. This result cannot be accomplished through the provision of a smaller sized drum, since it is de-' sired to take advantage of the larger sized drum at times when the tractor is not being used for hauling purposes, as hereinafter will appear.

In my copending application for patent serially numbered 532,992 filed January 31, 1922, I have shown, described and claimed the particular construction of winding drum and mounting therefor whereby av maximum of width of drum is obtained between the sides of the framework 10. Briefly, this drum is keyed to the shaft 11 at both of its ends, and at one end carries as a part thereof the gear 26 protected by a suitable guard 27. At the opposite end of the drum is the brake 28 cooperating with the band 29 and operating lever 30 to stop or retard the driving of the hoist when desired.

As shown in Figure 1, I have provided the as is common in the art of winches, providing two' drum portions, the smaller of which is shown to the left of the figure.- The cable is attached at one end to the drum in any suitable manner. If it is desired to wind the cable upon the drum preparatory to transporting the tractor to another place'or for use in hauling other implements, it'is permitted to wind npon the smaller portion of the drum until that portion has been completely filled. It is then passed through aslot in the partition 31 and permitted to wind upon. the larger portion until the re mainder of the cable has been wound. It

in the oil fields;

will be seen however that by winding the layers of cable upon the larger portion will be greatly decreased. The space saved 18 sufficient to permit of the easy coupling and operation of a draw bar in connection with the eye plate 25.

The full capacity of the drum is desirable in its use as a hoist attachment for a tractor Its two major uses here are to bail a well and to draw a casing from the well. To, bail wells requires a long length of cable, and it is necessary to carry, say, twenty-five hundred feet of three-eighth inch cable for this purpose; In drawing a casing from a well, a cable of larger size but not so long is required. In either event a drum of large capacity is desirable. In use it is usual to wind upon the smaller portion of the drum the excess of cable over that necessary to the particular use, which fore provided a guard 33 lying under the pinionwhen in its inactive position and pre venting the winding of the cable upon that portion of thedrum in excess of certain amount;

The guard is shown in Figure 2and comprises an attaching end secured to a, portion of the framework. It extends sulii: ciently forward to lie fully under thepinion and is curved upward slightly at its forward end. Being made of stiff material and bolted at the point 35 to the rail of the frame, it is suflicient for the purposes intended. -But in Figures 3and i I have shown a modification in which the guard 33 is provided with an attaching leg 34 braced c position shown in Figure 1. I have therewith a portionof the gear guard 27, and a,

connector 36 is provided for securing this end to said guard. 'Through this connector these two parts will mutually brace each other, and insure that the forward end of the guard will not engage the teeth of either the gear 26 orthe pinion 16. It will be ap preciated that the guard 33 will act as a guide to the operative of the hoist in determining the winding capacity of the smaller portion of the drum, and that it will form a-brake for the overwinding of the cable upon this portion of the drum. A suitable 1 ta e-2 Itwillbe obviou's'that' the provision of the sliding pinion obviates the necessity f" aiclutch and its mounting "so asto shift into an inactivekposition Within the contour of the drum "does not increaseythe. width necessary forthe hoist 'as-.a whole. This results in a distinct saving of space due-tothe absence of a clutch... It, also reduces the numberof elements in ahoist transmissiom as the pinion was necessary even. though a' clutch were present; V

In my copending application 1922, I have described-and "claimed. the

pinion mounting andnshiftingnmechanism shown herein. rBriefiy setforth, this: comgrooved collar'37 engaged by. the .yoke 17 secured to the shift rod21. ;.Upon aishifting V of therod 21 the pinion willbe movedl' into andout of operative relation with the. gear- 26. Therod 2l..'is mounted in'ears rising from; the bearings12, 12 and to 'limitthe movementof the rod in one 1 direction a pin 384s passed throughtan aperture in the rod and comesintoicontact with'the face ofgone of theears, as clearly. shown iniFigurel.

The limit of movement .ofthe shiftrod in the opposite direction is controlledbythe .pinionfacecoming into contact with-.the

endof the extension '32 of bearing12as" zheretofore eXplainecl: To shift thenrod a lever is {provided having one end attached.

to the framework and pivotally connected intermediate its'ends to the shift rod bya special connection 39, All of these parts are described more'in detail in mysaid co-' pending application. 7 V

'Beneath the guard 40 is a driving sprocket held to the shaft 20 and by means ofwhich power is received from the engine of the tractor through the mediuln of a sprocket chain and pinion on thejpulley shaft. The particular mounting ofthe sprocket on the shaft 20 is clearly shown in. Figure 5. The shaft 20 carries a collar 47 which is held by a set,

' screw against one'face of the bearingl2. On

the shaft at the other side of the bearing is mounted the hub 48, heldbya set screw, the I hub being provided with a'flange 49'to which is bolted the sprocket .15. It will be seen that the-collar sand hub48 abutting opposite sides of the bearing 12 and held to the shaft 20 constitutes means fofmaintaining the shaft against lateral movement in theframe.

From the bearing 12 to the right of Figure 1 there rise two lugs 41. in which is mounted a short shaft 42 having keyed thereto at one end the cam 43, which is encircled by the brake band 29. It will be apparent that-the movement of the lever 30 in proper direction 7 for patent I I serially numbered 532,9911fi1ed January-'31,
