FLEXIBLE SHAET.

Specification of Letters Patent.

Patented-Sept.f2,'1919.

Application inea' January 10, 1919. :serilNoL 276,467.

To all 'whomiz't may' concern:

5 Be' it? lmown that IQALERED MCCASKEY, a citizen'eflthe United States, and a resident of Chicago, in the county lof @ook and State' of'Illinois, have invented certain new and useful Improvements in* Flexible Shafts and Iido hereby declarethat the following is a full, clearjand exact description thereof, reference being had to the accon'ipanying drawings, and 'to the letters of Ireference marked there-on, whichformy a part of this specification.

This invention relatesto improvements 1n flexible 'shafts and consists of the matters hereinafter idescribed and more particularly pointed out in the appended claims. t

In flexible shafts of that type wherein each shaft unit is made'w'ith ai bearing notch in one end and a projecting lug at the other adapted to engage the corresponding bearing notch of an adjoining unit in suclrmanner as to permit of flexibility between the engaged shaft units, it' has been found desirable heretofore to use means for 'retaining the units in theirfassembled relation. For example, Letters `Patent No. 1,258,233 dated March 5,1918, illustrates thisty'pe of shaft, in which the units were tubular and wherein it was lfound necessary to employ rings withinthe unitsto retain the lugs within ithe bearing notches.`

Inl other instances, it has been found desiralble to 'employ a mandrel 4within the tu bul'ar units for'the same purpose. Such retaining mandrel 'may be, for example, a

`coiled spring 'er 'a flexible body such as a hose or metal ttibe whichwonld usually extend longitudinally of the shaft through several units.

The principal ebjec-t of inyinventionis to climinfatehll extra locking parts or devices in flexible shafts composed of inter-engaging shaft units of the general'type above referred to, and to accomplish the locking of the assembled units by means integral with the unit. yThis may be accomplished not only in that vtype 'of flexible sha-ft wherein the units areef'caist orforged tubular form, as well as 'withthose units'stam-ped out of a blankand `fashioned in tnbiilar form, but also with'iinitsiformed of rods or other solid metal. The integral locking means may be employed in various ways. For example, in the sheet metal type, the locking agency may be created when theblank is stamped out and may be brought into action as and when the blank is fashioned'in Atubular form. 'In thecasc of cast or forged ti'iliillar nnits or units 'out ont of ysolid l'rnetahthe "lo'cking agency may ljclci'c'ate'd anfhhroh'ght into ac" tio'nisA part of the shaftiass'embly eperation. Agai'min" tlie"ca'se ofa tiiblular'int,'the locking `agency may consist of integralpro- Je'ctions or protuberances" created" when the unit is lfrnie(l":'n`i` 1l which, after' two iinits are assei'nblled, may bebent i'nto'a dill'e'rent position to'engage' 'opposite sides of the adjoining unit.

The obje'ct ofthe inventin is toprovide a flexible lshaft, nfhich'is cheap to manufacture, easyto assemble,'ellicient in operation for its intended purpose,"an'd which is strong and" durable, thl's insnring greater amount ofse'rviee than has heretofore been attainable in ilcxiblelshaft-s as now made.

@ther objects and advantages willy appear as It proceed' with my specification.

Fig. 12 is a plan View 'of la blank from which Vthe unitillusti'ated in Figsff), y10 and llrnay bemade.

Referring new to that embodiment of my invention as illustrated in thedrawings'and .a length approximating its diameter. This proportion could be materially changed without departing from the spirit of the invention. l

,The body 2 of each unit l is provided at one end with a pair of longitudinally extending, diametrically opposite lugs 3, 3,

and at its other end .with complementary shaped, bearing notches 4, in which the lugs 3, 3, of an adjoining unit are adapted to engage in a manner coupling said units together. The diametric plane of the lugs 3 of one unit is arranged at right angles to the corresponding plane of the .bearing notches 4 in the same unit.k The advantage of such an arrangement is manifest.

Each lug 3 consists of a head 5 which is connected to the end of the associated body 2 by means of a neck 6, the lateral edges of which diverge outwardly as they approach said body. Each bearing notch 4, formed in the oppositeend of said body is of a contour corresponding to and adapting it to receive the lugs 3 ofy an adjoining unit. Each bearing notch 4 opens into the free end of `said body by means of a somewhat restricted passage or throat 7, through which the neck 6 of an associated lug 3 extends when said units are coupled or connected together. v

As shown in Fig.1, the left-hand, endmost unit 1 is coupled or connected by means of its lugs 3 in bearing notches 8 (which are identical to the bearing notches 4, before mentioned), formed in a terminal unit 9.l

Said terminal unitmay be either a tool holding chuck or. the like or it may constitutea coupling connection with a suitably driven member. f Y

10 indicates a suitable sheath or covering for the shaft which may comprise an innerA metallic member of coiled wire 11 and an outer member of flexible material 12, such as rubber or textile tubing. A collar 13 is fixed to the terminal end of said sheath, and a bearingk ring 14 is 4placed within sail collar to provide the proper `bearing for the terminal unit 9. y f

To prevent any tendency of the several coupled together or connected units to pinch` or cut into the sheathing and to prevent binding between the adjoining ends of the several units, especially when the shaft as a whole is arranged on ay curve or arc, it is desirable to round oil' the sharp edge at the ends of the body of each unit as indicated at 15, 15, in Figs. 2 and 3. At 16 is indicated a recess extending part way around the inner part of the bearing notch 4 and 17 is a small projection extend ing outwardly from the lug 3. These prof jections and recesses 17, 16 are complemental and serve to bind or lock adjacent units. 'Ihat is to say, the projections 17 hold thelugs 3 within the notches 4. The recess 16, being much longer than the width vof the, projection 17, affords a desirable range of flexibility of movement between said locked units. I prefer to construct the recess 16 and the projections 17 by a suitable mechanism after theunits are constructed,and as part of the shaft assembling operation. That is to say, the units 1 are first made without the recesses 16 and projections 17, and two units lare then assembled by placing thevlugs 3 of one unit within ythe bearing notches 4 of the next unit, and then the two units so assembled areA subjected to the action of a suitable press whichforms the recess 16 and then acts upon the lugs 3 and forces out suflicient of its `metal to form the projection 17. Manifestly, the only way to disassemble the units thus flexibly locked together is to physically remove one of the projections 17 from its lug 3.

In the form of my invention illustrated in Figs. 5 and 6, the units 1 are also tubular in form, and correspond in every ,particular with the units shown in Figs. 1 and 4 inclusive, just described. with this exception, namely: that -instead of subjecting ,the assembled units to the action of a suitable machine to form the recesses 16 and projections 17 there are no such recesses, and inilieu of the projections 17 of the first form, I construct on each lug`3 ay downwardly and inwardly directed l projection or lug 18 as clearly seen in Fig. 5. When the units having projections 18 are assembled, said pror jections are bent forwardly in prolongation of the lugs 3 and extend under and against the innersurface of the bearing notches 4, as clearly disclosed in Fig. 6, thus forming interlocking shoulders 19 and preventing th-e disassembly of the units.

In that form illustrated in Figs. 7 and 8, thev units 21 are made from solid metal, such for example as a rod;l `Each unit has a cylindric body 22, a longitudinally extending projecting lug 23 extending across one end, and at its-other end a complementary shaped bearing notch 24 in which the lug 23 of the adjoining unit is adapted to engage, will be manifest from the drawings, the diametric plane of the lug 23 being arranged at right angles to the corresponding plane of the notch 24.

When the units 21 are being assembled, a suitable press may form recesses 25, 26 on .its

opposite sidesof the body 22 .at tlie`oiiter @dsGS 0f the bearing notches 2t (simi-.ier .t0 tlierecess .1G of Fig. 2), and alsoprgss ont a lock projection You the enter lendskof Ghehe Said' projections 12T .being 1.1M-

roweixthan tbelength of the recesses 25,126, and adapted licenses@ there .as yilhletrated inV Fi i to lock two adj oiningl and assembled iiiiitsl, 2l from; disengagement.

- tliemargin a, it follows that on theopposite side c, there Will be one recess Z and two halt recesses l, CZ. The diametric ,plane of the recesses Z and d', when the blank 4is' folded into ltubular lform, will be .at right angles totliecorresponding planeet the projections 7) in the same unit.

The margin of the two projections b, b, on the sanieside of the blank B,.are beveled ott' at to constitute, in effect, `a projecting or overlapping part of the projections .6, b. The corresponding marginsof the .recesses d, (Z, onv the opposite side of `the blank are similarly beveled lat f, the latter ybeing 3indicated by dotted `ilines in Fig. l2.` It follows that when the blank B is bent up to form a tiibiilariinit,as C, and a secondi'blank then similarly termed, ,in ,juxtaposition to the formed unit C, as indicated at D, not only .willthe projections Z), b, ofthe ,iinit D properly engage `the recesses (l .and cl of the unit C, but the beveled overlapping .portions c of the unit .will have flocking bearing engagement with `the `beveled portions of the i'init C and thus prevent the ,disassociation of the units C and D.

Thus ,it will appear that whether the units arm-fashioned lbefore or diiringor as a part of .the shaft-assembling operation,4

provision madel for projecting lugs on one iinit to flexibly engage bearing notches in the adjoiningiinit, to form the shaft, .and that cooperating means, :integral .with each unit, is provided lto look lthe iinits in flexible relation and prevent disassembly.
