HOISTING MECHANISM Filed Oct 28, 1925 Patented Feb. 10, 1931 UNITED STATES PATENT OFFICE ROBERT C. OSGOOD, OF CLAREIMONT, NEW HAMPSHIRE, ASSIGNOR TO SULLIVAN MACHINERY COMPANY, A CORPORATION OF MASSACHUSETTS HOISTING MECHANISM Original application filed December 18, 1923, Serial No. 681,432. Divided and this application filed October 28, 1925.
While my invention relates generally to improvements in hoisting mechanisms, it is directed more particularly to improved motor and drum supporting means for. hoisting 8 mechanisms.
The hoisting mechanism of the type herein disclosed comprises generally a base, a motor, supporting means therefor carried by the base, and a drum driven by the motor. In
such mechanisms the motor is herein preferably of the electric type and, as is usual with such types of motor, lead wires extend substantially radially, from the periphery of the motor casing. Inasmuch as the drum partiallv surrounds the motor casing, it is essential that improved means be provided for allowing access to the lead wires. It is accordingly an object of my invention to provide such improved means and in a more specific aspect of the invention to provide means whereby the lead wires may extend through the motor supporting means. A further object is to provide improved means whereby the motor may be substantially freely longitudinally removed from the supporting means without any substantial interference from the lead Wires which extend through the supporting means. A further object is to provide means for permitting the longitudinal removal or insertion of the motor from the supporting means and yet permit a suitable operative relation between the supporting means, motor and drum.
In the accompanying drawings I have shown for purposes of illustration one form which my invention may assume in practice.
In these drawings,
Fig. 1 is an elevation of the hoisting mechanism partly broken away to show details of construction.
Fig. 2 is a fragmentary longitudinal sec tion of the motor supporting means showing means permitting removal of the lead wires therefrom. I
The disclosure in this application is the same as that in my copending application. Serial No. 681,432, filed Dec. 18, 1923, of which this application is a division.
Inasmuch as the invention herein resides in the means for permitting removal of the mo- Serial No. 65,445.
tor with. its projecting lead wires, the hoisting mechanism in general will be only briefly described. A base 1 is provided at its central portion with an upstanding standard 2 forming a split clamp and provided with a bore 3 within which a motor 4 is insertible. The motor preferably has a close slidable relation to the bore walls while no clamping action is being exerted. The standard 2 is split as at 5 to permit passing a pair of bolts 6 through lugs 7 formed on the free ends of the standard 2 to clamp the motorwithin the bore 3. The drums 8 and 9 are j ournaled at their adjacent ends on the periphery of the motor casing as by roller. bearings 10 and 11 While the remote drum ends are j ournaled in suitable standards 12 and 13. Suitable gearing is provided between the armature shaft 14 and the drums,
The motor herein shown is preferably of the electric type having lead wires projecting from the casing; but it will of course be understood that many other types of motor might be used which, if having a generally similar characteristic such as a projecting'element, would permit utilization of my inven-" tion. The standard 2 has a radial boss15 carrying a terminal plug 16 to which may be connected. the lead wires 17 which extend substantially radially from the housing of the motor 3. To permit insertion or removal of the motor there is formed in the boss 15 a chamber 18 having communication with a slot 19 extending to one side of the standard.
2. By this construction, the lead wires (should an electric motor be used) or other laterally projecting part of the driving m0- tor are accommodated by the passa eway or slot 19 when it is desired to slip t e motor take the hoisting mechanism apart, the bolts or screws fastening the standard 13 to the base 1 are first removed together with the portion of the brake mechanism which is sesured to the base. The standard 13 and the drum 9 are then slipped from their position by longitudinal movement to the left. The ring 20 may now be removed; and loosening of the bolts 6 will permit the motor casing to be moved out of the clamp or standard 2. It is of course obvious that the lead wires 17 must first be disconnected from the plug 16 so as not to interfere with the removal of the motor. These wires pass without diificulty along the slot 19 which has been provided in the clamp2.
In order to present a substantially continuous bearing surface and also to close the open end of the slot 19 for prevention of oil leakage through the slot 19, there is provided a removable annular ring 20 adapted to slidably engage the motor housing periphery adjacent the side of the standard 2 thereby to close the open end of the slot 19. An annular groove 21 is provided in the ring to receive a suitable packing 22 while the roller bearing 11 engages the outer side of the ring at points spaced inwardly from the packing 22. The drum has a flange 23 overlying the ring 20. While the above construction is utilized on only one side of the central standard, this is because the motor need be removed from only one side of the standard although it is obvious that if for any reason it should be desired to remove the motor from either side of the standard, this construction could be duplicated on the other side thereof. It will also be noted in Fig. 2 that the drum flange 23 abuts the standard 2 at a point radially beyond theslot 19 so that, should it be desired to dispense with the ring 20, the slot 19 would nevertheless be closed. It is or course clear that this construction is also adapted for a single drum hoist.
While I have in this application specifically described one form which my invention may assume in practice, it will be understood that this'form of the same is shown for purposes of illustration and that the invention may be modified and embodied in Various other forms without departing from its spirit or the scope of theappended claims.
