HOISTING DEVICE.
Specification of Letters Patent.
Patented Aug. 23, 1921.
Application filed August 2, 1920. Serial No. 400,616.
To all whom it may concern Be it known that I, HIRAM MYnRs, a citi zen of the United States, residing at Sterling, in the county of hiteside and State of Illinois, have invented certain new and useful Improvements in Hoistin Devices, of which the following is a speci cation.
My invention pertains to hoisting devices, and has reference more particularly to mechanism for the operation of silo tamping devices, well drilling machines, pile drivers, and other machines of that kind- One of the purposes of the invention is to provide a simple and efficient means for quickly connecting the power mechanism of the machine with the drum devices, upon which a cable or chain is wound, and as quickly release the same, to permit the dropping of a weighted object on the opposite end of the cable.
Another purpose thereof is to provide means for the interruption of the movement of the drum, the instant the cable is unwound therefrom, and prevent rotation of the drum rearwardly, which might result in the breakage of some of the parts.
The construction, arrangement, and op eration of the various parts of the machine will be more fully apprehended from the following specification, reference being had to the drawings accompanying the same, in which:
Figure 1 is an elevation,taken left hand side of the machine.
Fig. 2 is a similar view, from the right side thereof.
Fig. 3 is a invention. I
Fig. 4 is a detail of the brake. devices.
Fig. 5 is a detail of the cable guiding mechanism. 7 r r Fig.6 is an enlarged plan view of the drum connecting mechanism, with part of the wheel 11 broken away, to more fully disclose such mechanism.
Corresponding parts are indicated by similar reference characters throughout the several figures. I
1 indicates the frame of the machine, supported for portable purposes on front carrying wheels 2 and rear carrying wheels 3. Mounted on the forward part of the frame is a motor 4, having a main drive shaft 5, on which is fixed a pulley 6, connected by a belt 7 with a pulley. 8 on a shaft 9, journaled on the frame 1, transversely thereof. A shaft from the fragmentary plan view of the 10 is also rotatablv mounted on the frame, parallel with the shaft 9, and adapted to be driven therefrom by means of a gear-wheel 11 on the shaft 10, in mesh with a gearpinion 12 on the shaft 9. 1
Supported on the shaft 10, so as to have independent rotation thereof, is a drum 13, at one end of which is a collar 14, in close proximity to the wheel 11. The collar 14 is of cam-face formation, with a shoulder 15, which is engaged by the end of a pin 16, having a pivotal connection with one end of a lever 17 fulcrumed on a bearing 18 fixed to two adjacent spokes 19 and 19 of the wheel 11. The pin 16 passes through an opening in a plate 19*, whereby the pin is held inclose contact with the shoulder 15, causing the wheel 11 and drum 13 to rotate in unison. The pin 16 is held normally in engagement with the collar 14 by means of a coiled spring 20, connecting the end of the lever 17 with a spoke 22 of the wheel 11.
Fulcrumed on the sp0ke22 is a lever 21, one end of which is formed into an arch 23, which passes over the spring 20. -The inner end of said arch is adapted for engagement with a recess 24 in the pin 16, when said pin is moved outwardly, such engagement operating to hold the pin in outward position, disconnected from the drum 13. The engagement of the lever 21 withthe pin 16 is v maintained by means of a coiled spring 25, connecting the long end of said lever with the spoke 22. The lever 21 can be released from engagement with the pin 16 by means of a push-pin 26, supported beneath the frame v1, and adapted to be moved inwardly into the path of the long end of said lever, forcing the short end thereof away from the pin, and permitting such pin to move inwardly into engagement with the collar 14. Connected with drum 13, so as to rotate therewith, is a sleeve 27, on which is fixed a sprocket-wheel 28, connected by a sprocketchain 29 with a sprocket-wheel 30 on a shaft 31, rotatably supported on the frame 1. Fixed to theshaft 31, outside the plane of the wheel 11, is an arm 32, carrying a cam 33, which is adapted to be brought into the line of movement of the long end of the lever 17, forcing such end inwardly, and withdrawing the pin. 34 is a cable, connected at one end to, the drum 13, and at the opposite end to a tamping device, or other weighted object which it is desired to raise for a predetermined distance and then perdrum 13.
mit to drop of its own weight. The cable passes around a sheave 35, mounted on a shaft uniting a pair of guide-plates 36, slidably supported at their lower ends on the rear axle A, and at their upper ends on the shaft 31. This provides a guiding device for the cable which is capable of lateral movement in following the cable variation as it is being wound on the drum, or unwound therefrom. I
i In. the operation of the machine, assuming that the lever 21 is holding the pin 16 in withdrawn position, with the cable 34 entirely unwound, the pin 26 is. forced inwardly, tripping the lever 21, and permitting a'quick movement of the pin inwardly, into engagement with the collar 14. The movement of the wheel 11 and shaft 10 is then imparted to the drum 13, winding the cable 34 thereon. The movement of the drum is communicated to the shaft 31 at a reduced rate of speed, causing a comparatively slow movement of the arm 32 and cam '33, in the direction indicated by the arrow. 7 In practice, assuming that it is desired to give four rotations to the drum 13, the shaft 31 would in the same period of time describe about a four-fifths revolution, bringing the cam into contact'with the lever 17, instantly releasing the pin 16, and permitting the weighted object at the outer end of the cable to drop. The end of the pin 16 is beveled, so that it will be self-releasing upon reach ing a point near the outer end of its movement. This insures the prompt release thereof, in case it should not be fully withdrawn by the action of the cam, or in case of any tendency of the lever 17 to react after passing the cam.
The unwinding of the cable causes the drum 13 to revolve at a rapid rate of speed, with a tendency of the movement of the drum continuing after the cable is'fully unwound. This would result in the rewindingof the cable in the opposite direction, with a possibility of breakage thereof, or of some of the parts of the machine. To obviate this difficulty a brake mechanism is provided, which is constructed and arranged as follows: Pivoted on a bearing of the frame, as at a, is a pair of brake- jaws 37 and 38, each partially encircling the end of the The arm 38 is projected upwardly, and pivoted thereto is an 'arm 39, connected at its lower end by a link 40 with the arm 37. The upper end of the arm 39 is connected by a rod '41 with a chain 42, fitted to be wound on a sheave 43, fixed to the shaft 31. A yieldable attachment of the arm 39 and rod 41 is provided by a coiled spring 44, and an adjustment of the length of the rod may be had by means of a turnbuckle of usual patternfitted therein.
The chain 42 is wound and unwound from the lower side of the sheave 43, so that when the cable 34 is Winding the chain is being unwound. On the contrary, when the cable unwinds the chain is wound, so that at the instant the cable is entirely unwound, and it is desired to stop the movement of the drum, the chain exerts a tension upon the rod 41, moving the arm 39 toward the rear of the machine and causing the brake-jaws to tightly engage the drum, interrupting the movement thereof. As soon as the drum commences to rotate in the opposite direction again, the tension is released.
What I claim and desire to secure, is:
