HOIST.

` Application `filed May S1,

T 0 all 107mm may concern.'

Be it known that l, ALBERT' H. NELLER, a citizen of the United States, residing at Fairfield, in the county of Jeffersomf State of iowa, have invented a new and useful Improvement in Hoists, of which thefollowin is a specification. n

l y invention' relates to` hoists having gearing to increase the lifting power oimthe hoist, and it consists oi' an arrangement oit the parts whereby a hoistingwheel is mount- 'l ed at one end of the gearing and an eXtension or extensions are secured to the opposite end of the gearingv whereby an additional wheel or wheels may be mounted on said extension or extensions at some distanceirom the gearing and said. hoisting wheel or wheels will operate in unison with the first mentioned hoisting'wheel. Also, it consists otbraces secured to a casing which usually encloses the gearing to support the extension or extensions, and oit other improved features set forth. in the speciiicationuand de- Iined in the claims. p I

In the accompanying drawings which form a part of this specification, Fig. l is a side perspective rci a hoist mounted on an overhead track-way and embodying my invention. Fig. 2 is an enlarged perspective ci the part or" the hoist containing the gearingand the first hoisting wheel mounted therein. Fig. 3 is a similar view of the part containing the second hoisting wheel which is mounted on the extension. Fig. 4 isI an enlarged 'perspective of `the part containing theA gearing with the. casing removed and certain' portions` partlybroken away to obtain a better view of somle oi' the interior mechanism. Fig. 5 is a vertically disposed longitudinal section on line 5-5 of Fig. fl.

Gis a vertical transverse section on line 8-'6 or" Fig. 4f., looking in the direction oi the arrow. Figs. 7 andS are detail views which will be later explained. Fig. 9 is a transverse section on line 9"-9 of 8. s. i0 and ll are additional detail views.

Fig. l2 is a slightly enlarged transverse section on line 'l2-l2 oi Fig. 5, the cut away portion of Fig. 5 being replaced to make the structure complete.

.Referring to the drawings, A represents 1921. Serial No. 473,697.

an elevated traclnway on which trolleys B are mounted. The trolleys are preferably arranged in pairs joined together by connectingdevices C. D represents the main frame containing the gearing and D a supplemental frame between which and the main frame a hoisting wheel E is mounted and shown vin Fig. 5. The wheel is preferably provided with sprockets e, (see Figs. 5 and 6) to engage the links of `the hoisting chain F.

G represents an extension frame in which the second hoisting wheel is mounted. The mlain frame D and the extension frame G are attached to the connecting devices Cof the adjacent trolleys by means of a swivel containing a transverse pivot I, the object of which pivot is to revent the bending or breaking of the swive head should'either of the trolleysrun off the track-way, orbecome so disconnected from the end of the hoist to which they are attached thatsaid end would'drop down to an .approximately vertical position.

In Figs. 1 and 2, the'rm'ain lframe D is shown provided. with a casing J which removed in Figs. 4 and 5 to give a view of the interior mechanism. K represents la chain wheelupon which afhand chain L is mounted and by means of which the gearing ofthe` hoist is operated. The wheel K ismounted on a shaft M which has a small gear Non its inner end',v (see Figs. 4 and 5.). A revolving trame kO carrying two dual or diiierential gears and P', the larger oi which gearsare in miesh with the small gear N, is mounted in themain frame. On the circumference of -the main frame is an internal gear ,Q which. is iny mesh with the smaller of the `dualor differential gears F.

The hoisting wheel E is provided with an extension R (see Fig. 5) which is rigidly fastened by a key K,.as shown in Fig. l2, or otherwise rigidly secured in the revolving trame O, whereby they will turn in unison. Theshait' M to which the hand wheel K is affixed, is journaled in the wheel E and its extension fR, and will .turn freely therein. f

handr chain L will operate the entire'4 2 fr i/ise with tlie stationary internal gear Q, and

` being also rotated, will cause the revolving ling chain VF according tothe direction of the rotation. Consequently a pull on the mechanism and the leverage onthelioisting chain F will be largely increasediby the gearing. To provide for the operation of the second hoisting chain lfl, lfuse a shaitfi, preterablv ot tubular material., l ati/ii; to the revolving Jframe (l, shown. Ainy Figs'.j l ando, ac'oiipling member T has portion T adapted-toldo inserted in the adjoining end of'the;tubular shaft S, and tobe prete erably secured thereto by vbolts The cou-- plin'g member T is preferably? connectedl to the revolving traine by,passing'.the enf tended ends ot the axles t, on which the gears P andyP are mounted, th-rough holes in the extended ends' 'ot tliecoupliiig mei-liber and securing' them in this position by' cot'-A ters, as 'sliown' in Figs. stand v Thebther end of the shaft Sl is'y passed Y througliopeningsi'n the extension Jiraine G with the chain F.

where it maybe lfreely rotated by itscon= nection with tlieievolvable Vtroine i). nthis end oit the shaft and' within the ,traine aiixed a hoisting wheel to' receive the hoisting chain H. riilhis hoisting wheel (not v shown in detail in the drawings) isoi' the saine diameter as the ywheel and is preferably:`p'rovided with similar sprockets vto engage andoperatevv the chainipH` in' unison Tojhold the extension frame Gf 'fixed 'ielation'with the main traine D, l 'use braces U, preferably of tubular materiakan'd three in number.'l Tubular shaped sockets V are formedy on ythe face of the casing'J and'` also on 'the adjacenty facey of the frame G, vand after passing over ythe hoisting wheels, are

the ends of thebraces U areL inserted in said socketsfand are lseciiredthereiiipref;

erably by lbolts b'. liiuse the ycasing .l is securely lheld in; place on the frame Df by means 'of bolts d, (shown in Fig. 4)" and therefore theiranies D` and G 'will be securely held in iixed'relationj by the braces U.

The upperl slack ends of ,the hoisting chains F and ll,kdesignated by F and H',

'preferably connected to' adjacent 'ends of the extension shait S, and are arranged to wind and unwind thereonas the lower ends of the chains which carry the loads are raised and lowered. To assist in, winding and unwinding the chains, I usev guides W yto slide 'on the shat'tSv 'and also on lone ot the braces U. To prevent the sticking of these guides in sliding onthe shaft Sand brace U, (preferably the lower brace) I use roll- 'i-ers X, as most plainly'shownin Fig. 10.

The rollers ars locatedon the guidesso as to run on opposite sides of the brace U and will thereby prevent it from catching or sticking thereon, as itV would be liable to do'wit'hout the rollers. v f

In using the hoist, thefloads `which are attached to the lower ends ot the hoisting .chains F and lH, (loads not shown), vwill sometimes swing around and twist the chains so they will not run straight to the vhoisting wheels but will climb on one side `ifis'showfnby F l8,9 and il, the hollow V portions oi these guides, through 'which the `chains pass, 'are made to Vloosely tit the general contour ot the links of the' chains, and thechains willbe straighteiiedv in passing through them, by the angular' cornei'sg coining iii Contact lwith the sides ot the links 9 sliouldthe chains become twisted.I By this means the' chainsl will Vbe straightened and f will be prevented Atrom climbing upon thek edges of the hoisting wheels. The guidewY v is' pivoted at its upper end betiveen` lthe trames D andD on one side of th'e'wh'e'el E at Z, andthe guide 'Y `is pivoted near its lower end between the frames on the otherV side of the wheel E at Z', as shown in Fig. 6.

lt isA necessary sometimes that the lower end of the guide Y'sho'uld be free toswing side-wise toa* certain extent to accommodate the line Aot draft of the chain. Therefore it 'is pivoted at its iippere'nd This is not necessa'ry in the descending or' slackends F and H of the chains, and tor this vreason the yguide Y' is pivoted'near its'low'er end.y The guide Y" Ais provided with an upstanding prong 7i `which is adapted toproject'into the recess vin the center of the lhoisting jwheel between the sides e, topreven't the slack chain from followingA around thel wheel on its underl side. Also, with upstanding prongs c' to further assist in separating the sla'ckchain from the wheels to form the loop F", and alsothe loopI-l.

Itl is obvious that additional y.extensions may be made by placing'additionaltrolleys on the ltrack-way and connecting to saidtrolleys additional extension iraines G, similary to that shown in Figs. l and 3. Sockets V will;

have to be placed on the outertace of the frame@ and ythe additional trame or liframes it used, except the last one similar to those on the inner face of the lrainey G, or other iso 1 ,asefioe means will have to be provided for the attachment thereto of additional extension braces, similar to the braces U. .An additional extension shaft or shafts willy also have to be provided and coupling means will have to be used to connect said shaft or shafts to the preceding extension shaft.

As shown in the drawings, the hoist is adapted to lift twol separate loads in unison at one operation, the loads being attached to the chains F and H, but by using `additional extension frames and extension shafts with wheels thereon carrying hoisting chains, as explained, it will be adapted to lift additional loads. 0n the other hand, if only one load is to be lifted, the extension shaft S and braces U may be disconnected from the gearing and from the casing J, in which case it-.may be used as an ordinary single hoist, thus making it adaptable to a variety of uses either single or plural as may be required. Also, the loads, whether single or plural, after being lifted maybe readily carried along the elevated track-way. It will be observed, as most plainly shown by Figs. l, 3, 5 and 6, that in addition to the transverse pivot l, there is also a longitudinal pivot fm in the swivel connecting together the trolleys and the frameseD, Dv and G. This longitudinal pivot will permit the tilting of the hoist side-wise to a considerable extent, should this be required, without straining the swivel connection or disarranging the trolleys on the track-way. A guard for the chain wheel K is represented by a and r is a pivoted cover for an opening in the casing J, said opening being convenient for the oiling of the gearing within the casing. In Fig. 5 a common arrangement is shown at X and adjacent thereto, whereby the chain wheel K will be automatically thrown into rigid connection with the shaft M or be released therefrom, which arrangement being common in the prior art need not be explained.
