ELEVATING PULLEY. 7 APPLICATION FILED OCT- 28. 19I5.
Patented Sept. 5,191
WILLIAM J. BLACK, OF CHICAGO, ILLINOIS.
ELEYATING-PULLEY.
Specification of Letters Patent. Patented Sept, 5, 1916.
Application filed October 28, 1915. Serial No. 58,385.
certain new and useful mprovements in Elevating-Pulleys; and I do hereby declare that the following-is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and tothe numerals of reference marked thereon, which form a part of this specification.
Various types of pulleys have been constructed for use in connection with linkbelt and other belt hoisting and conveying machines, but in practically all types of such belts, that is, belts to which scoops or buckets are secured, some of the material to be hoisted or, conveyed spills and lodges between the outer surface of the rim of'the pulley and the inner surface of the belt. The material is thus compressed and ground between the pulley and the belt, scraping and cutting into the belt, and tending in a very short time to so damage and-mutilate the belt that replacement of the same becomes absolutely essential, in order that the elevator may be kept in working operation.
This invention relates to. an improved type of pulley for use in elevating or con- .veying machines wherein material which tends to lodge between the pulley and belt is permitted to pass through the outer surface of the pulley into the interior thereof, from which it is forced out at both ends of the pulley into the material retaining compart-' ment.
It is an object of this invention to construct an elevating pulley having openings in the outer surface and in the ends adapted to permit material to pass through the surface and out at the ends of the pulley.
It is also an object of this invention to construct a drum shaped pulley having end web members, connected together by T-bars in such a manner that material dropping between the T-bars is allowed to work its way.out through the end web members of the pulley.
It is also an object of this invention to' construct a drum pulley embracing a shaft having web wheels mounted thereon and secured together by means of a double conicalinner drum mounted on the hubs of said wheels and with cross bars connecting the peripheries of said wheels, said bars spaced from one another to permit material to drop therebetween upon said conical inner drum, from wh1ch the material slides outwardly through the end web wheels.
It is furthermore an object of this invent10n to construct an improved type of drum pulley wherein an inner hub member is conically tapered toward both ends and upon which are secured apertured end wheels, having cross members,- fequally spaced from each other to form the periphery of the pulley to allow material to pass between said. cross members and drop upon the hub to be worked outwardly through the apertures 1n the end wheels.
It is finally an object of this invention to construct an improved type of drum pulley adapted to permit material to pass through the surface thereof on to the exterior of a drum and out through the ends of the pulley.
The invention (in a preferred form) is illustrated in the drawings and. hereinafter more fully described.
On the drawings, Figure 1 is a section through a hopper showing a conveyor belt trained about a drum embodying the princ ples of my invention. Fig. 2 is an end view of the drum. Fig. 3 is a sectional view taken on line '33 of Fig. 2, with parts shown in elevation. Fig. 4 is a sectional view taken on line 44: of Fig. 3.
As shown in the drawings,v a hopper or material container of any'desired make is represented as a whole by the reference numeral 1, and journaled in the bottom thereof is a shaft 2, upon which is mounted a drum pulley comprising spider wheels 3 and 4:, keyed upon the shaft 2, near the ends thereof, in parallel relation to each other. As clearly shownin Fig. 2, said spider wheels are formed with radially disposedintegral ribs affording discharge openings therebetween, adapted to permit material falling upon aconical inner drum 5, to be discharged from the drum through the apertures in said spider wheels. .The ends of said conical inner drum 5, are adapted to fit over circular flanges 6, integrally formed on the inner surface of the wheels 3 and 4, thus centering the conical drum 5, and holding the same spaced within T-bars 7, secured in grooves cut in the rims of said end wheels 3 and 4, and circumferentially disposed in parallel relation with one an- Wheels, to afi'ord a hearing or tread surface for a belt 8, passing over said drum pulley as clearly shown in Bi L The operation is as ollows: As shown in Fig. 1, the drum pulley is mounted inside of a hopper or material container of any desired type and near the bottom thereof. Passing around. said pulley is a continuous belt, the buckles secured thereon acting When at the bottom of the hopper to scoop the material. During the elevating operation some of the material conveyed by the buckets may be spilled or jarred out of said buckets and in falling to the bottom of the hopper, particles of the material tend to lodge between the outer surface of the drum pulley and the inner surface of the conveyer belt. The tread of the drum pulley being made up of spaced parallel bars 7, however, permits the material to drop down between said bars upon the-conical inner drum 5, and due to the taper of said drum toward both ends, and also due to the revolving motion of the pulley, the material is gradually Worked toward both ends of the pulley and discharged out through the apertures provided for the purpose in the spider Wheels 3 and 4:. V
I am aware that various details of construction may be varied through a Wide range Without departing from the principles of my invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art,
I claim as my invention:
1.- In a device of the class described, shaft, spider Wheels keyed near the ends thereof and each having a circular flange in" tegrally formed on the inner face thereof, rims on said Wheels, a conical drum between said wheels rigidly secured to said flanges, and spaced bars secured to the s of said Wheels and extending therebetvveen, the same providing openings for material to drop upon said conical drum to be ejected laterally through said spider Wheels.
2. in a device of the class described, a
shaft, spider Wheels keyed near the ends thereof and each having a circular flange integrally formed on the inner face thereof, rims on said Wheels, a conical drum between said Wheels rigidly secured to said flanges, and E -bars secured to the rims of said wheels and extending there-between, the same providing openings for material to drop upon said conical drum to be ejected laterally through said spider Wheels.
In testimony whereof l have hereunto subscribed my name in the presence of two subscribing Witnesses. WILLIAM J. BLACK.
