Application filed January I4, 1905; Serial No. 241,071.

To all whom it may conce/rn Be ity known that I, ALBION E. Notons, a citizen of the United States, residing at- Cambridge, in the count-yet Middlesex and State vof Massachusetts, have invented an Improvement in Hoisting Apparatus, (Case AQ of which the following' description, in connectionwith the accompanying drawings', is aspecieation, like letters on the drawings representing like parts.

My invention consists in improvements in hoisting apparat-us; being particularly concerned Wit-hthe cont-rol and operation of load-lifting and load-carrying devices.

My invention will be best understood by reference to the following specification when taken in connection with the. aeco1npanying drawings, showing one specific elnbodinient thereof, While its scope will be more particularly pointed out in the an pended claims. v In the draWings,-]5`igure l shows in plan the. tivo drums of a double drinn hoistlng engine in'ivhich is embodied one :torni ot.

my invention; Fig. 2 is a side elevation oi the same; Fig. 3 1s an elevation partially 1n section, ot one of the hoisting drums shown in Fig. 1; Fig. l is asimilar view of'the other of the tWo drums; Fig. 5 is a similar View of a modified form of my invention; Fig. G shows diagralninatieallythe arrange; nient ot' the eontrollingropes in one system to which my invention may be applied;

" and Fig. 7 is a detail of the ltrolley carnage `re )resented in Fim 6.

-eferring to Figs. -1 to '4, inclusive-the -rope winding drums-a and b 'arerotatably mounted upon the respective drui'nsha'fts a' and of; i U

pon the, drum shafts are txedly secured the ititermeshingt gears and D?, so.

Y that, inV the particular arrangement here showin, the',moveinentotishaft a' in one direetion,4 1s accompanied by 'a corresponding movementof the shaft b inthe opposite direction. y Any 'suitable or appropriate ineans for transmitting driving movement to one or the' other ofthe tivo lshafts. may be employed; such, eXan1ple,'as the"driving pinion' o shown partially broken aiiiay in Fig. 1 and connected yto be driven by any suitable motor (not shown); or the motivev means,Y whether steam, electric or otherwise,

may be directly connected lto one yofthe said i drum shafts.

In ordeil that `the, two d rnlns may each be driven by and with its respective shaft ivhendesired, I have provided clutching means7 such clutching means herein being' trietional. In respect to the clutching means, the two drums are substantially the same and reference ishad to Fig. il, where I have shown secured to and carried by the inner tace ot the gear a2 suitable conical friction blocks d, adapted to `frietionally engage suitably-shaped surfaces upon .the tiange of the drum o, -When the latter is moved lengthwise' the shaft n', thereby to drive the said drum directly and With the speed of the shaft 11,. i

Any suitable clutch operating means Jfor :forcing the drum into engagement with the` friction clutchy may be employed, and I have here shown oneconst-ruetion which is particularly advantageous in connection with the. invention as hereinafter described.

At the opposite end of the drum from'the gear a2 and bearing against the drum hub, is a collar e, against which presses a sliding cross key e, the latter being engaged by `the sliding and axially arranged rod e2. Idearng against the rod is the end of the' operating screw et, which may be turned by means ot. the hand lever e5 (Figs. l and-2) thereby act-ing to force the rod e2 an the pin e toward and against the collar e lto compel frict-ional enga-gement between .the Winding drum` and the gear. of the said lever clutch is insured spring c.

The drum a. may be directly clutched to the shaft, as' described, or may `be driven, when desired, in the same dinection but at. ay slower speed by-ineans of planetary gearing, as follows: Keyed 4or otherwise secured ,di engagement of the through the action of the Ito the shaftl a to rotate therewith, isxthe pinion f engaging with one or more intermediate pinions f', the latter journaled upon and Carried by the drum a. The pinionor pinionsL-'f are in engagement with an internal gear f2, formed upon or carried by aro* tary member f3, the latter being journaled to rotate about the' shaft ai. The'` rotary member f3 is encircled by the brake band f", Which-,may be tightened to-'ela'sp a suitable brakesurface upon the Iface of the said rotary member; thereby acting tooppose or stop lrotary moi/ement thereof. IVhen the brake band is loosened, the member f is free forgrotation and the pinion f exerts no effect y (n reverse mo vementpinion y is 'provideih .keyed to the shaft 7;" and engagingI one or more internieiliate pinl ions g; thc latter being lilteivisein eligagement with an internal gear g2. Here, hoiv.

ever, the pinion g is yournaled upon and carried by the rotary member ffl; and the internal gear g2 is t'ornied upon or secured to the drinn itself. vVith this relation of the gears, when the rotary member g is held by the brake band the movement ot the winding drum is the reverse of that of the shaft b. lt will thus be seen that by means 2.5 of the controlling levers which tighten the brake bands and the friction clutches, and

' which, as'is usual in this class ot apparatus will be arranged within convenient reach of the operator, said drums may be clutched to the shaft either together or independently for direct drive, or driven through the planetary reduction gearing at a relatively lower speed and with a/ reversal of the relative movements of the two drums.

ln Fig. 5 l haveshown a different form of drinn corresponding to the drinn a' but which is capable of substantially the same movements. Instead o t' clutching the gear a directly to the drum fr, the said gear is 4o clutched to the rot-ary member f, vwhich v herein ispi'ovided with friction surfaces adapted for that purpose and is loeatcd'between the drum and the gear. This causes lau interlocking of the planetary gearing and compels the drum a. to move with the said gear. When unclutchcd, the friction band f" may be tightened in the usual way to cause aY slower movement of the winding drum. Obviously, a drinn similar to drinn t) may also be constructed upon the plan shown in Fig` ln Fig. 5 l have also shown a different form of .clutch operating device. The gear a2 is tixedly secured to the shaft c and the latter is provided at its opr positeend with a collar el bearing against which is asleeve e", which may be forced outward .from the stationary abutment c by the twin operating screws 0"; the latter being turned by suitable links and levers (not G0 herein shown) but similar to those shown in my reissued l atent No. 12,085. lVhcn said screws are turned to torce' the sleeve outward frein the abutment, the sleeve. c? engages with the collar c and draws the eutire Shaft with the attached gear z2l in the saine direction. `forcing the friction ineinhers ot' the clutch into clutching engage-v ment. lVith either the clutch-operating de; vice shown in Fig. 5 or that shown in Fig.

'3, the operating iii/einher or members are 10- 70 cated outside ot` the journal or abutment-,cf of the engine frame and l am enabled to bring the drinn close to thc said abutment; this heilig ot particiilar-advantage with the construction ot', drinn shown in Figs. 3 and 75 where the strain which is introduced by the. friction hand f* may be brought nearly into line with the said journal or abutment. 'lliis 'feature is a point wh'icligives pre-ference to the drinn construction shown in Fig. 3. lt is to be observed that in the construction exhibited by Fig. 5 the friction blocks engage the more slowly rotating rotary member f so that the force required for holding the friction clutches in engagement is less with a pair of drums constructed as in Fig. 5 than as in Fig.' 4.

ln Fig. (S l have oiitlined diagran'nnatically a hoisting system to which my invention as described may be usefully applied. o This comprises a cable or trackway system along which is adapted to run a trolley /i carrying a suitable load-lifting device, such as the clamshell bucket or grab ii'. The rope winding drums are represented di agra mmatically at a and b and from these the ropes .Zi and Z respectively lead tothe trolley carriage approaching the latter from opposite directions." Theirope 7c which after passing" over guide sheave /i upon the trolley passes around and aboutl sheaves c and o2 on the grab, and thence to the trolley to which it is secured. Theil-ope Z passes about a guide shea ve h2 upon the trolley, thence about the sheave v3 upon the grab and thence to the 105 trolley, to which itis secured. The grab illustrated is ot'4 an ordinary,well-known construction. When both ropes are length'- ened, the grab is lowered and wheirthe ropes are shortened, the grab is raised.

lVheu one is lengthcned relatively to-the -other. the jaws of the grab are opened or closed. .The trolley is controlled and maintained as desired in any fixed position by the endless controlling rope ne attached thereto 115 and passing about ,the drinn u adjacent. `he drums a and D; the said drinn nl having appli d thereto a. foot-brake (not shown)` un! dei the control of the operator. y

llfith the drums a and constructed and arranged as described, the operator is en-,H abled to traverse. the carriage with its'attached load in either direct-ion'desiredby rel asing the drinn n, throwing in the friction clutches and starting the driving'mo- 125 tor in the required direction. This, as is l evident, turns the drum to wind in .one of the ropes Lor 7c, while similailyfunviiinding the other, and., as will be sceii from"Iiifgf; this will cause the trolley to travel along'l the cable or trackvvay. at the highest speed'ot which the engine is capable without altering the elevation of the attached load. lVhen, however, it is desired to hoist the load upon the trolley, the vdrums are unclutched from the shaft and the brake bands tightened to render eilectiveI the planetary gearing. Thislresults in reversing the relavtive rotation of the drums. so that both druiifis may be turned to wind in both of the hropes l and .71. and raise the load but at a greatly reduced speed, thus rendering more effective the power of the driving motor.

ln Figs. 6 and 7 I have shown an attachment for the trolley h adapted to engage and hold the gral) when tha latter is elevated. Thisiconsis'ts in a pair of levers 0 and 0 pivoted at 02 rand having jaivso, the latter adapted to catch andehold the pin o5' of the slieave n upon the grab. y The opposite ends ot the levers are secured to links 09 and 07, connected each tothe roll 08 to forni a toggle joint.' The tivolevers are, slotted as shown at ,the point Where/the pivot o2 passes through them, s'o that as the grab is lifted the pir-r o5 pushes the leversupwardly' and therefore apart to perni`-t the pin tolenter Vbet-Ween them, after' Whic they drop from their own Weight' and drai` together, secur- 1 ing and l y lfore'lease the grab the jaivs must he drawn apart, 'and this is accomplished/hy lifting up the-roll. 0S. ,lifted and thcfjmiis sprgad to release the grahffivheneveidesired/by the `operator lat l the hoisting engine/If/provide a stationary rope or cable p. rf'ii'ich passes over suitable guide sheaves-ian the trlley and' beneath therolloa, being lixedlvsecured'at one end .of-the' track or'cableJivay and at the' opposite and to the hellc'ianl lever p", `to which at'teiis attached tlie depending rope p2, secured to the levei'p. The lattenmay be noved at ivill'by the operatorio-tighten on the rope p and thus raise the roll o* and release the grab. wWhilel` have herein lt'or illustrative pur- -poses shown one form of my invention and with reference to one special application, it will be obvious that my invention mayloe applied in many other ways than that herein shown. and may he modified extensively without departing from the spiritthereof.
