MoToR MOUNTING.

Application filed-October 24, 1924. Serial No. 745,545.

To all whom it may concern:

Be it known that I, HARR V. HAIGI-IT, a citizen of the Dominion of Canada, and a resident of Sherbrooke, Province of Quebec, Canada, have invented a certain Motor Mounting, of. which the following is a specification accompanied by drawings.

This invention relates to hoists, but more particularly to the winch type of hoists which is especially useful in hoisting or moving comparatively light loads.

1 This type of hoist is usually mounted; on a portable frame and is actuated by hand through the medium of a crank attached either directly to the'shaft upon which a drum carrying a cable is mounted or to a separate drive shaft through reduced gearing. A hoist thus operated, however, is lim ited to loads which can be moved when the crank passes through that are of its revolution where only the weight of the operator can be applied.

While this method of hoisting is practical within certain limits, it does not prove satisfactory in all cases, due in part to the limited turning power which can be applied by means of a crank and partly to the low rate of speed at which a hand winch may be operated. It has been found that through the use of a suitable attachment, a reversible motor may be substituted for hand power and that a more rapid and greater turning power may thereby be obtained.

One of the objects of this invention is to detachably support a mounting for a reversible motor on a winch.

Other objects will hereinafter be disclosed in the following specification and accompanying drawings, illustrating the invention in one of its preferred forms.

Figure 1 is a plan view showing a mounting on a winch and supporting a pneumatic motor,

Figure 2 is a perspective view of a yoke for a motor mounting,

Figure 3 is a perspective view of a bracket for a motor mounting, and

Figure 4 is a perspective view of a wedge for holding the motor mounting in position on a winch.

Referring to the drawings, the invention is shown mounted on a hand hoist or winch A and supporting a pneumatic motor B of the portable air drill type in operative relation with the Winch for applying motive power to the winch. Fluid pressure, as for instance,- compressed air, 1s supplied through a flexible conduit O connected to the control handle D of the motor B. In this instance the motor is assumed to be of the reversible type, reversal of which is controlled by a sleeve E suitably connected to a control valve (not shown). On one side of the winch is shown a yoke F mounted on the ends of the drive shaft G and a drum shaft H which are designed to project through suitable apertures J and K in the yoke F. a

In order to hold the yoke F securely in place, a clamping member L, preferably in the form of an angular bracket, is adapted to be attached to the side M of the bearing stand O by common means, as for instance, the tap bolts P through the holes P. A projecting arm Q, of the bracket L having a slot R is adapted to extend through a suitable slot S in the yoke F to receive a wedge T.

Suitable means have been provided for holding the motor B in the yoke F and to this end an aperture U in a leg V of the yoke F is designed to receive a reduced portion W of the removable handle X of the motor B, while a slot Y in a leg Z of the yoke F is designed to accommodate the handle D which is preferably held in place by a suitable pin 7) removably disposed in the hole 0 within the leg Z. I

Assuming that the motor B is mounted on the yoke F and that the crank has been removed from the drive shaft, the yoke may then be mounted on the projecting ends H ill and K of the shafts c and G respectively.

At the same .time a chuck f of suitable design on the motor B will receive the polygonal end 9 of the drive shaft G whereupon the Wedge T may be placed in the slot R of the bracket L to hold the yoke firmly in position.

Suitable automatic brakes not shown.) within a casing h are used for holding a drum stationary when the load on a cable 70 has reached the desired height, whereupon the motor may be reversed and the load lowered by means of the motor.

The motors to which this invention is particularly applicable are of the light portable rotary type, asv for instance, pneumatic or electric drills such as are usually found in shops where compressed air or electricity are available, and which, oftentimes not being otherwise employed, may readily be substituted for a winch crank, thereby temporarily converting a hand vvlnch into a motor driven hoist and providing a more rapid and efiicient means for operating the winch.

I claim:

1. In combination with a winch havin "a plurality of laterally extending shafts, a yoke adapted to fit over the ends of the shafts to be held in position thereby, said .yoke being adapted to receive a motor and to hold the same removably in operative relation with one of said shafts.

2. In combination with a winch having a plurality of laterally e'xtendingshafts, a yoke adapted to fit over the ends of the shafts to be held in position thereby, said yoke being adapted to receive a motor and to hold the same inoperative relation with one of said shafts, and means to hold said yoke removably in position on the shafts.

3. In combination with a winch having a plurality of laterally extending shafts, a yoke adapted to fit over said shafts to be held in position thereby, one end of the yoke being apertured to receive the handle of a. motor, the other end being forked to receive another handle of said motor, and to hold the same removably in operative relation with one "of said shafts.

4. In combination with a winch having a plurality of laterally extending shafts, a yoke adapted to fit over said shafts to be held in position thereby, one endjof the yoke being apertured to receive the handle of a motor, the other end being forked to receive another handle of said motor, and to hold the same in operative relation with one of said shafts, and means to hold said yoke removably in position on said winch.

5. In combination with a winch having a plurality of late-rally extending shafts, a yoke adapted to it over said shafts to be held in position thereby, one end of the yoke being apertured to receive the handle of a motor, the other end being forked to re 'ceive another handle of said motor, and to hold the same in operative relation with one of said shafts, and means including a slotted inember attached to the winch and a tapered member removably arranged within the slotted member to hold the yoke against removal from the winch.

V In testimony whereof I have signed this specification.

HARRY VERCOE HAIGHT.
