BUCKET-HOIST.
Specification of Letters Patent.
Patented Apr. 7, 11914.
Application filed June 16, 1913. Serial No. 773,936.
and State of New Jersey, have invented a.
certain new and Improved Bucket-Hoist, of which the following is a specification,
My invention relates to bucket hoists and particularly to that type in which the bucket is hoisted in a bight in the hoisting rope, the object of my invention being to provide means to cushion the strain incident to the initial hoisting motion after the bucket has been closed.
In the accompanying drawings, Figures 1, 2 and 8 are diagrams showing several embodiments of my invention.
In the customary construction of hoists of' this general character, one end of the closing rope and one end of the holding rope is made fast aloft to the trolley or frame-work of the hoisting tower, depend ing on the design, and after passing around sheaves in the bucket, the other end of each rope is taken to the closing and holdingdrums respectively of the hoisting machine.
structure in general. My invention relieves" this condition. In its simplest form, (shown in Fig. 1) it consists of a heavy spring 2 on the dead end of the closing rope 1 so that some definite yield can be counted on during the first instant of acceleration of the bucket 3 upward immediately after the jaws meet. Only the closing rope wound on drum 4: is here shown, the'holding rope attached to the frame of the bucket being omitted for clearness. Another arrangement is shown in Fig. 2 in which a heavy counterweight 5 is used with many parts of rope multiplied by sheaves 6 so that when the jerk comes the counterweight will tend to move very little and thus its inertia will be substantially less than that of the bucket, and will therefore relieve the rope by substituting the inertia of the counterweight for the inertia of the bucket. The spring 2 may obviously be arranged in the dead end of the rope 1, thereby still further cushioning the strain,
In hoists using a counterweight to assist the lifting of the bucket the same counterweight may be utilized to cushion the initial hoisting strains if the rope be arranged as shown in Fig. 3. In this case one end of the counterweight rope 7 will be opposed to the dead end of the closing rope 1 as a shock absorber, while the other end of the counterweight rope is wound on the counterweight drum 8. In Fig. 3 l is the closing rope fro-m the bucket which is wound in on the closing drum 4 while the other end is made fast preferably, though not necessarily, through a spring 2 to one end of a lever 9, while on the other end of this lever one end of the counterweight rope 7 is attached. The lever l'is used because the amount of counterweight for lifting the bucket may not be exactly right for absorbing the shock of the closing rope and this difficulty may be overcome by fixing the fulcrum of the lever at the proper point.
Various other devices for efiect-ing this end will readily suggest themselves.
I claim as my invention 1. In, hoisting apparatus of the type described, a hoisting rope having a fixed end, drum end and an interposed hoisting bight, a hoisting bucket on said bight in the rope and a yielding device of predetermined resistance arranged at said fixed end of the rope to cushion the initial hoisting strains after the bucket is closed, in combination with a counterweight rope having a fixed end, a drum end and an interposed bight in which a counterweight is arranged, and means in connection therewith for exerting an auxiliary cushioning action, substantially as described.
2. In hoisting apparatus of the type described, a hoisting rope having a fixed end, drum end and an interposed hoisting bight, a hoisting bucket 011 said bight in the rope and a yielding device of predetermined re sistance arranged at said fixed end of the rope to cushion the initial hoisting strains after the bucket is closed, in combination with a counterweight rope having a fixed end, a drum end and an interposed bight in which a counterweight is arranged, and name to this specification, in-the presence' means in connection therewith for exerting of two subscribing witnesses, 7 an auxiliary cushioning action and a rock lever to the ends of which the iixed ends of AUGUSTUS SMITH said hoisting and counterweight ropes are attached, substantially as described.
In testimony whereof I have signed my Witnesses:
