I g Q I Be it known that I, EDWARD H. DUTOHER, a citizen of the United States, residing-at Siegfried, in the county of Lehigh and State of Pennsylvania, have invented certain new and usefullmprovementsin S eed-Control ling Mechanism for Centrifuge Oil Extracting and Filterin Machines, of which the following is a specification.
My invention has relation to a speed-controlling mechanism for a centrifugal oil extracting and filtering machine; and in such connection it relates more particularly to the construction and arrangement of such a mechanism and being a'division of an applicationv for a patent filed by me under date of July 3, 1905, under Serial No. 268,105
The principal objects of my invention are, first, to provide a basket for extracting oil by centrifu al force with means for automatically an' manually retarding and stopping the rotation of the basket; second, 'to provide the basket for the oily material with wings actuated partially by air and partially by centrifugal force to prevent excessive speed of rotation of the basket, which speed by tending to shift the oily material therein causes an uneven distribution of the weight of the material in the basket, and thereby shakin of the same and an uneven wear of the bearings thereof, and, third, to provide the basket with means to permit of the retarding and stopping of the basket when reuired.
The nature and scope of my invention will bemore fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, in whic Figure 1 is a view, partly in front elevation and partly in vertical central section, of a basket for the oily material within a stationary housing and wings pivotally connected therewith to automatically retard the rotation of the basket and a ring normally held out of engagement with the basketadapted, when manually raised, to engage the same to retard and stop the basket, constituting features of my p'resent invention. Fig. 2 is a horizontal sectional view of the up%er portion of the housing of the machine 0 ig. 1 and the basket for oily material arranged therein and also illustrating the construction and ar-' plate b 1n its proper'position.
rangement of the wings connected with the outer perforated wall of the basket and held in engagement therewith'by springs. Fig. 3 is a horizontal sectional view of the u per end of the standard ofthe machine and i lustrating in top or plan view the means for raising the rin to manually retard and stop the rotation of the basket. 1 Fig. 4 is a detail view illustrating, partly in section and partly in side elevation, a cam and rod for actuating the ring; and Fig. 5 is a detail view of a por-" tion-of the basket, illustrating in side elevation one of the wings connected therewith and springs for holding the same normally in an inoperative position. I
Referring to the drawings, a is the standard of the machine, to the upper end of 'which is suitably secured a housing a, annular in cross-section, having a cover a provided with an 0 ening a This opening is normally closed by a lid a, which, by means of a leaf-spring a secured to the under side of the lid a, is normally connected with the housing a by engaging projections a thereof, as shown in Fig. 1. The housing a is pro vided with a centrally-arranged projection a,
whlch serves extending into the standard a,
The shaft a asa support for a shaft a within the housing a serves as a support for a basket 1), adapted to receive material more or less saturated with oil, which is to be extracted therefrom. The basket I) preferably consists of an annular disk or bottom plate I),
strengthened by ribs bfihaving a central upwardly-projecting portion 6 forming a chamber b and a support for a ball-bearing bicentrally engaging theupper surface of the sh aft a", and a roller-bearing 'b", surrounding the shaft adjacent to the ball-bearing If. These bearings, in conjunction with a roller-bearing 6 arranged in an extension 6 of the pro j ection b serve to support the plate I) on the shaft a," and to permit of an easy turning thereon. The plate I) adjacent to. its perimeter is provided with a flange 6 which holds aperforated cylinder b, carried by the In addition to the perforated cylinder 12 the plate I) isprovided with a second cylinder 1), preferably formed of coarse-meshed wire-netting, which,
in conjunction with the cylinder 1), forms an 20 ,wall b.
points.
45 h, assisted by centrifugal force.
and-2. The wire netting, forming an inner side wall b", is preferably held in position by annular-springs b ,-',which tend to force the same-against the, filter material c In, this 5 basket b is placed the material from which oil is'to be extracted, and below'the bottom plate ,andsecured to the extension I) of the projection b is"a'rranged an annular diskd,'
which is provided with blades d, against whi h a jet of steam is directe issuing from the nozzle e and impinging against the blades d; Thissteam, by the intervention of the blades (1, sets the disk (1 and the basket I) in ,rapid rotation, and by the same and centrifu- 5 ga force all oil in the material placed inthe basket I), aswell as impurities and other extraneous matter'in the same, are liberated therefrom and forced into the filtering material c by readily passing through the inner The filtering material 0, however, arrests all these impurities, not alone of the oil extracted from the waste material, but also those previously held by the oily mate rial, and only permits the extracted oil .to
ass through the-openings in the outer wall At a certain speed of rotation of the basket I) the oily material packed therein becomes dislodged and tends to unbalance the basket by crowding together at certain vweight of the material causes a shaking of the basket during rotation, and thus an uneven Wear ofthebearings b 1), and 5 thereof, In order to overcome this objectionable feature,
the basket Z; is provided with Wings h, pivotally securedto the perforated'side wall I) and held "in engagement therewith by leafsprings h, as shown in Figs. 1, 2, and 5. The free end of each wing h is slightly curved out- 40 ward, and thus forms an obstruction to'the air in the chamberb, formed by the basket I) and housing a, which air, when the speed of rotation of the basket 1) becomes too great, offers sufficient resistance to open the Wings The resistance of the air against the now open Wings h issufi icient to reduce the speed of rotation, and this eliminates the danger of shifting of the oily material in the basket I).
thereto is arranged a plate '5, surrounding the shaft a Opposite the disk i is arranged a ring 7c, having a projection is, preferably passing through a pipe a and terminating above a cam Z, carried by a shaft Z, supported by the standard a. When the shaft Z is turned by means of a handle Z the cam Z is brought into engagement with the projection Zc,
which, by raising the ring 7c, brings the same into engagement with the plate Z, and thus The uneven distribution. of the,
Beneath the turbine-disk d and secured retarding the speed of rotation'of the basket I). By the manipulation of the cam Z the ring is is brought to bear with greater or less force against the disk 7;, and thu'sthe speed of rotation of. the basket can be controlled at will and the 'b'asketbrought to'a standstill when desired.
' Having thus described the'nature and objeots of my invention, what I claim as new,
chines, a stationary housing having a basket for oil-containing material rotatably arranged thereimwings held in alinement and connected with said basket and adapted to be moved radially thereto by centrifugal force and by air acting upon a portion thereof, to automatically retard excessive s eed of rotation of said basket by exposing t e entire surface to the resistance of the air, and means supported by said housing and adapted, when manually actuated, to en age said basket to retard and stop rotation t ereof.
3. In a speed-controlling mechanism for,
centrifugal oil extracting and filtering machines, a stationary housing having a basket for oil-containing material, means connected with said basket adapted to actuate the same, wings held in alinement and connected with said basket and adapted to be moved radially thereto by centrifugal force andby air acting upon a portionthereof, to automatically retard excessive speed of rotation of said basket by exposing the entire surface to the resistance of the air, a ring arranged below the actuating means for said basket having an extension and a cam adapted, when actuated, to raise said ring by engaging said extension,
to force the same against the actuating means of said basket'to retard and stop rotation thereof.
Intestimony whereof I have hereunto set my signature in the presence of two subscribing' witnesses. Y
EDWARD H. BUTCHER.
