HARRY E. JENKINS; or JOPLIN, MISSOURI, assronon or ONE-HALF'TO GEORGE H.
" Y sLaDE, or JOPLIN, MISSOURL HOISTING MECHANISM.
To'hll whom itma y'c oncern:
Be it known-that I, HARkY- E; JENKINS,
' citizen ofthe United States, .residing at Joplin, in the county of Jasper and State of Missouri, have. invented certain new and useful Improvements in -Hoisting .Mechanism, of which-the followingis a specification.
My invention relates to improvements in hoisting mechanism, adapted to .be driven by an'electrie notor, or; any other source of power, suitable for use'in mines 'or' the like, while not necessarily restricted to such use.
The recent application ofthe electric motor as a prime mover for hoisting mechanism, employed in mines or the-"lil(e,.ha's
created a demand for a drum embodied in such hoisting mechanism, "which will, upon starting, wind up or move the cableslowly, without jerks, and quicklyf-accelerate"the movement of the cable until the,niaximui l v speedis reached. I am'aware that attenipts have heretofore "been made" to accomplish this result," but these have not generally proven satisfactory. For instarrce,v it has been roposedv tokmploy a stepped coneshaped drumfor this purpose. l he',disad- 'vantages of the cone-shaped 'drum are -nu- I merous, among whichmay be mentioned the fact that the movement of the cable is gradually accelerated from the minimum to .the maximum circumferences of the-"cone, the intermediate"circumference determining the average speed of the upward gitravel of the cable, and the maximumvelocity of the cable being reached only when the can, bucket, or the like hasreached the end o'fl its travel and must be stopped. A further disadvantage of this cone-shaped drum is that it can receive nly' apsingle'layer ofcable, and for shafts of considerable depth, the drum would have to be extraordinarily large and unwieldy, to hold sufficient cable to meet the requiremenm. i'
I have discovered that if the drum of the hoisting mechanism is provided at one end with a groove or slot, inclined inwardly with respect to the longitudinal axis of the drum, and in the direction of thesheave or pulley over which the cable passes the friction be tween the cable and the adjacent end or edge of the drum would be reduced to the minimum, and highly satisfactory results obtainable.
The invention also consists of improved Sp ecifieationof Letters Patent.

An important object-of theinvention is to provide a machinfe of the above mentioned character, which {is "simple in construction, IIIGXPBXISIVG to manufacture, and rellable in operation.
Other objects and advantages of the inof the following descriptionf I In the accompanying drawings forming a .part of this specification and inwhichlike: numerals are employed to designate like parts throughout the same, Figure leis aside gemsmet hoisting nechanisin embodyiiig the invention, Fig. 2 is centralgvertieal.

is a detailed section taken 3 01i line 6 -6 of i r35 Fig. 3, Fig. 7 is aplanview of the drum and sheave or pulley, and, Fig. 8 is a detailed section through the clamp. ff
In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 10 designatqs a base ofthe hoisting mechanism, as; whole, upon which is suitably mduntedean electric motor 11, having an armature sh 12'. This armature shaft is connected,) means of a coupling 13, with a shaft of the hoistingmechan'isni, This shaft is jour naled through stationary bearings lfias shown. v
Mounted upon the shaftl4 isa cylindrical drum 16, embodying ends or heads 17 and 18, having hubs 19, mountedupon the shaft 14. The cylindricaldrum lfiis to be revolved by an expanding or contracting clutch, or any other approved means to lock it to the 7 shaft 14, but not shown. These ends or heads 17 and 18 are} rovided with flanges 20, ex tendingeutwai fl beyond the drum lfiifor a substantial distaribe, as shown. i
The end or head 18 is provided with an annular groove 21, which is inclined in means of a lever '19. or the like.
exterior-of the end or head 18 and is held thereto by means of a-clamping late 24, attached'tothehead 18 by nieansio bolts or the like. This cable 22 extends upon the outer side of the head 18, .as surplus cable,
and is rolled or coiled in a space 2.6, afforded by -a flange 27, and held in the space by strips- 28, detachably connected with the head 18 by bolts 29 or'the like.
As more clearly ShOWIl in- Fig.6, the numeral 30 designates an equalizing wedge, rigidly mounted-within the bottom of the groove 2.1 and having its large end disposed adjacent the opening 23 through which the cable passes, such wedge tapering away from suchopening The large .end of-the wedge is of substantially the thickness of-the cable, whereby the next'turnof the cable will pass overthe first turn without forming' a prononnced hump. Y
numeral 1 designates 33, the tension of which'may beregulated by adjusting the nuts 34. The inner-ends of these hooks engage with coractin'g hooks: 3 3, attached to a brake-band 36.: having a suitable lining 37, operating. in groove 38 formed in the adjacent annularllange 20. One end of this brake-band, as clearly shown in Fig. =2, is connected with a stationary rod 39, while its opposite end s pivotally connected with a vertically swinging crank 40 rigidly mounted upon a rock-shaft 41. This rock-shaftadapted ,to' be operated by The function of the liooks32 and associated elements is to'pro ide-mcans for holding the brake band out o: improper contact with the flange 20, when-toe brakes are not set.
In operating hoisting mechanism in mines or the like, the end of the-cable winch is connected-with the can or bucket ordinarily quickly wears out necc-ssitating'sueh end of the cable being out off and the cutcnd being again attached to the can; This of course shin-tens the cable, and in order torompensale for this, I have provided the means intion is imparted tothe drum 16, by a clutch, or any other approved meanspnot shown. -'The diameter of the bottom wall of the AS clearly shown in'Fi'gs. -2 and 1, the
a supportingrail or member, surrounding the adjacent flange 20 "and held stationary with relation thereto.
This supporting rail is apertured at suitably. spaced intervals for receiving reci-procz-itong" hooks 32-, moved oi'itwardly by coil springs.
cluding the clamps 28 and associated elements to retain the surplusaount of the cable upon the outer side of the head 18, whereby when the end of the cable is cut off for the purpose above stated, the clamp 24 '.7qmay be loosened and a suitable amount of the surplus cable fed into the slot 21, subsequently to which the clamp is again tightened up.
W hen the motor 11. is running, its rota groove 211bei-ng small, upon starting, the cable is pulled s owly, which movement however isquickly accelerated untilthe cable completely fills the inclined groove 21, at which time the maximumsp'eed of travel ofthe cable is obtained,.'the-cable thenbeing wound upon the periphery of the drum 16, in any suitable number of layers. -I have found that, by having agroove 21 inclined inwardly with respect to the longitudinal axis of the drum 16 in alinement with the pulley or sheave 21' (Fig. 7) that the cable is not cut or worn by contact with the edge of the drum 16, upon passing thereon: The rotation oft-the drum 16 may be ar rested by depressing the-brake -le ver"or' pedal/i2 which swings the crank 40 downwardly and tightens the brakegband, the springs 32 yielding 'to-permit' of the proper contraction of the brake-band. I It is to be undei's'tood that the'form of my inventionherewith shownand described is to be taken-as a preferred example of the same, and that various changes in the. shape", size, and-arrangement of parts-inayb'e ref sorted to without departing from-the spirit v of the invention or the'scopeof -the'- subjoined claims.
Having thus described the invention,- what I claim is:-' J 1. In hoisting mechanism a winding drum provided near one end with a cable receiving 10 groove which has a Width substantially equal to the diameter of the cable and has a substantial depth so that a plurality ofturns of the cable may be arranged thereimszud groove-being inclined inwardly with rela-' 5 t on to its longitudinal axis" a 2. In hoisting mechanism, a winding drum provided near its ends with flanges a ndtad jacent one flange with a cable rec'erving I groove which has a Width substantially equal to the diameter ofthe cable and has a substantial depth so that a plurality of turns of the cable ma be arranged therein, saidgroove bein inclined inwardl with r ect c D V to the longitudinal axis of thefdrum. I
3. In hoisting niechanism, -a' drum pro vided with flanged ends and having a groove formed in one end and inclined inwardly with respect to the longitudinal axis of the drum and an opening leading into the 129 groove and passing'to the exterior of such end, a cable passing through the opening and adapted to be wound within the groove and upon the drum, and means to clamp the cable to the exterior of the grooved end of the drum.
4. In hoisting mechanism, a drum provided with flanged ends and having a ve formed in Zone end and inclined inwardly with respect to the ion 'tudinal axis of the drum and an opening ormed in the grooved end and leadin into the groove and passin to the exterior of such end, a cable passing through the opening and adapted to be wound "within the groove andupon the drum, adjustable means for clamping the cable to the exterior of the grooved end, and means carried by the exterior surface of the grooved end for receiving sur plus cable.
5.'In hoisting mechanism, a drum pro vided with a cable receiving groove having a lateral opening adjacent the bottom of the groove for the passage of the cable, and an equalizing wedge arranged within the bottom of the groove adjacent the lateral opening and tapering away from the opening.
