Application filed October E 1836. Serial No. 215,799. (No model.)
T0 (225 whom it may concern:
Be it known that I, DANIEL S. WAUGH, a citizen of the United States, and a resident of Denver, Arapahoe county, Colorado, haveinvented certain new and useful Improvements in Hoisting-Machines, of which the following is a specification.
My invention relates to improvements in hoisting-machines of that class wherein rotary motion is imparted to a rope carrying or hoisting drum from a steam-engine or other motor through the medium of friction-clutches, and has for its objects the provision in a device of the class named, and in connection with the hoisting-drum thereof, of peculiarlyconstructcd driving mechanism, means for throwing said mechanism into or out of operative connection with said drum without exert-ing undue end or side pressure or thrust upon the main or drum supporting shaft and its bearings, means for imparting an increased area of frictional surface to the drum-driving clutches, and means for imparting the proper adjustment to the several elements comprised in the device, all substantially as hereinafter set forth, and illustrated in the accompanying drawings, wherein similar figures of reference denote similar parts.
In said drawings, Figure l is a a top plan view of a hoistingmachine constructed in accordance with my invention. Fig. 2 representsa longitudinal section th erethrough,taken on the line A B of Fig. 1. Fig. 3 is a transverse section thereof, taken on the line C D of Fig. 2, looking in the direction of the arrow on. Fig. 4 represents a transverse sectional view taken on the line B F of Fig. 2, looking in the direction of the arrow n. Fig. 5 is a similar sectional view taken on said line E F, looking in the direction of the arrow 0. Fig. 6 represents a transverse sectional view taken on the line G H of Fig. 2, looking in direction of the arrow 1',- and Figs. 7 and 8 represent detached detail views of parts of the operating, mechanism.
It will be understood that motion may be imparted to my improved hoisting-machine by any desired form of motor, operated by any desired poweras steam, water, wind, gas, &c.-and I have not, therefore, herein shown, nor shall I hereinafter describe, any particular form or description of motor or machine for accomplishing this purpose, but will confine my description solely to the construction and combination of the several elements comprised in the present embodiment of my invention, and to the manner in which said elements co-operate when the machine is in operation.
In thepresent embodiment of my invention I provide the base or bed 1, which may be common both to the hoisting-machine and to the motor which operates said machine, with pillow blocks or standards 2 and 3, that form bearings for the opposite ends of the main or drum carrying shaft 4, as shown. I provide the opposite ends of the shaft 4. with collars 5, which bear against the outer surfaces of the pillow-blocks and prevent longitudinal movement of the shaft.
Upon the shaft 4, adjacent to the pillowblock 3, I mount a drum, 6, one end of which is provided with a flange, 7, about which a brake-strap, 8, extends. (See Fig. 3.) To the flange 7 I secure an annular flanged casting, 9, the opposite surfaces of which are engaged by friction-blocks, presently to be described.
Upon the shaft 4, within the flange 7 of the drum, I loosely mount a disk, 10, and provide one surface of said disk that toward the flange 9 and upon opposite sides of the middle of said diskwith projecting portions 11, and provide said portions with apertures 12, which receive friction-blocks 18, preferably of wood, and which at times, hereinafter stated, bear against the flange 9. I provide the opposite surface of the disk 10, opposite the middles of the projections 11, with lugs or cars 14, between which is pivoted in pairs, at 15, angular dogs 16, which extend thence through apertures 17, formed in the disk 10 outwardly and between projecting ears or lugs 18, formed upon the.
opposite ends and sides of a casting, 19, which is loosely mounted upon the shaft i, adjacent to the disk 10. The ends of the dogs 16 are 9 connected by pivoted links 20 with said casting 19, as shown. Between and to each pair of dogs 16 I pivot a block, 21, from which extends a rod, 22, to and through a spur-wheel, 23, which is mounted upon the shaft 4: outside of the flange f the drum 6, and is held from rotation upon said shaft by a key, 24, as shown The free ends of the rods 22 are screwthreaded, and adapted to receive adjusting nuts or burrs 25, which bear against the outer surface of the spur-wheel.
I provide one surface of the spur-wheel 23- that adjacent to the flange 9 of the drum 6- with projecting portions 26, having apertures to receive friction-blocks 27, which in practice are placed opposite the blocks 13 of the disk 10, and cooperate with said latter blocks to clamp the flange 9, as will be hereinafter ex plained.
Rods 28 extend from the casting 19 at opposite sides of the shaft 4 outwardly through the spur-wheel 23, and are connected at their outer ends with arms 29 and 30, which project from semicircular disks 31 and 32, that extend about the shaft 4 outside of the spur-wheel 23, and are connected together by bolts 33, which extend through laterally projecting ears formed on said disks 31 and 32, as shown.
The inner edges of the disk- sections 31 and 32 are placed and operate in a peripheral groove, 34, formed in a short sleeve, 35, which is placed partly upon a boss or hub, 36, formed upon the spur-wheel 23 and partly upon a boss which projects from the pillow-block 2. The lattecnamed boss is provided upon its opposite sides, within the sleeve 35, with inclined peripheral slots 37, into which pins 38 project from the sleeve 35, (see Figs. 2 and 7,) for a.
purpose hereinafter to be explained. An arm, 38, extends downwardly from the sleeve 35, and is connected by a bar or rod, 39, with a lever, 40, pivotally connected to the base 1, as shown.
The outer ends of each of the arms 29 and 30 of the semicircular castings 31 and 32 are apertured to permit the passage of screwthreaded adjusting-bolts 41 and 42,which pro ject from the spur-wheel 23.
As the drum Bin operation is moved slightly in longitudinal direction upon the shaft 4, its flange 9 might, when said drum is heavily laden, remain for a time in contact with the friction-blocks of the wheel 23, when it is desirable to instantly remove said flange from said blocks. To obviate this objection I provide the shaft 4 within the drum with a collar, 43,-secured in place by a set-screw, 44, and surround said shaft with a coiled spring, 45, thcfopposite ends of which bear, respectively, against said collar 43 and the inner surface of the drumliead, or against a boss formed thereon, as shown in Fig. 2.
I connect the opposite ends of the brake 8 of the flange 7, respectively, with a foot, 46, formed upon the base 1, and an adj ustable screw-threaded rod or bar, 47, which connects to a lever, 48, pivoted to said foot 46. The opposite end of. said lever 48 is connected by links 49 with the lower curved end ofa lever, 50,'also pivoted in said foot 46, as shown. The teeth of the spur-wheel 23 are engaged by gearteeth formed upon a spur-pinion, 51, which is mounted upon the main shaft of the motor.
The operation of my device is as follows:
It being understood that the frictionblocks 13 and 27 of the casting 10 and spur-wheel 23, respectively, are normally maintained at adistance from the flange 9 of the drum, said casting 10 and spur-wheel rotate in unison with the shaft 4, inasmuch as. said shaft andspurwheel are keyed together, while the drum 6 It will is maintained in stationary position. also beunderstood that the castings 19,31, and 32, move in unison with the spur gear-wheel and casting 10. \Vhen it is desired to cause the drum to rotate, the lever 40 is drawn outward, which action, through the connecting, bar or rod 39 and arm 3S,causes the sleeve:
35 to rotate upon its bearing, and by said rotation to be moved, through the medium of the inclined slots 37 andpin 38, toward the.
spur wheel 23. The connected castings 31 and 32, from their described connection with said sleeve 35, will also be moved toward said spurwheel, and, inasmuch as said castings are, through the rods 28, connected with the casting 19, it also will move: in unison with the parts named, thereby, through the dogs 16, moving the disk 10 in. the opposite directionfi. 6., toward the flange 9. The movement of parts thus described will bring the friction- blocks 13 and 27 of the disk 10 and spur-wheel 27, respectively, into engagement.
with the opposite sides of the flange 9. The continued movement of the parts named will cause thelinks 20-to swing into alignment 9 from. engagement with the friction-blocks as will be understood. This latter action. of the parts described is aided ingreat measure by the spring 45 of the drum 6, the said spring operating in manner hereinbefore described.
Movement ot' the lever 40 and its 1 The adjustable bolts 42 and castings 31 and 32 serve to draw the spur-wheel backward should such wheel from anycause not be moved by the action of the parts above described.
In applying the brake S to the drum the lever 50 is drawn backward, which will at first:
rapidly move the lower arm of the lever 48 through the medium-of the links 49. As, however, said links will be swung upwardby the above-described. movement, the upward speed of the point at which said links are connected: to the lever 48 will be gradually decreased until said links are nearly in alignment with said lever, and so operateas a lockto holdthe brake-band 8 in close contact with the flange until said brake is released therefrom by the opposite movement of the lever 50.
proper adjustment as to length is imparted to the brake-band 8 throughithe rod 47..
, The
It will be observed from the foregoing description that the main or drum bearing-shaft is practically free from the longitudinal and lateral strains consequent in machines of this class upon the direct connection to such shafts of the clutch-controlling mechanism.
If desired, material other than wood may be employed as i'rictioirblocks.
Modifications in detail of construction may be made in the within-described invention without departing from the spirit or sacrificing the advantages thereof-as, for instance, the friction-blocks may extend entirely-around the casting 10 and wheel 23, respectively, or said blocks may be attached to the opposite surfaces of the flange 9.
