Specification of Letters Patent. A lication filed May 27, 1910.
CEliTTRIFUGAL MACHINE.
Patented J uly 4. .1911. set-m1 No. 563,734.
To all whom it may concern:
Be it known that I. \Vnnconn H. Lawson, a citizen of the United States, and a resident of the town of Poughkecpsie, in the State of New York, have invented certain new and useful Im provements in Centrifugal Machines, of
county of Dutchess and which the following is a specification.
My invention relates to centrifugal separating machines, and the object of my invention is to provide a novel means of driving the separator bowland to provide means whereby said bowl may run in balance when rotating at a high rate of speed.
lteferrii'ig to the drawings which form a part of this specification, Figure .1, shows a vertical sectional view of the driving shaft of a milk separator with the bowl mounted on its upper end and in its normal position when the bowl is not rotated. Fig. 2, is a similar view illustrating position that it usually takes whenslightly out of balance and running at a high speed.
Fig. 3, is a modified form in which the shaft is provided with two yielding springs,
indicated in this czse by rubber bands, and in which the shaft is provided, midway between said bands, with a circular bead which serves as a fulcrum.
Referring to Fig. 1, A, indicates the se arato'r bowl which is provided with a cone shaped opening A in which opening is formed an annular groove A in which is located a yielding-spring B, which may be formed of rubber or other suitable yielding material.
Referring to Fig. 2, I have illustrated a separate casting I) which is formed cone shape and carries the element B, to permit the element D to be removed and renewed when it becomes worn. 0, indicates a vertical shaft which is driven by a suitable gearwhich cooperates with the worm thread (J'. The lower end of the shaft C indicated by C is located in a proper bearing and the shaft C is supportcd'at at its surface to prevent any lateral movement thereof. Herctoforc it has. been customary to provide means to allow the shaft 0 to move out of its vertical position to a prcdctcrmined degree to assist in l'ialanciug the I My improvement consists 'in'providyielding spring matherotation of the shaft (1 imparts motion to the bowl A, and when the bowlA runs out of balance, it will ing the bowl with the the bowl in the projecting means. a
suitable point on tend to swing to one side as illustrated in Fig. 2, until it finds its true center of rotation. I prefer to form a groove in the shaft C at C to increase the surface contact of the driving shaft with the material 13 and also assist in preventing the accidental dis placement of said material.
Referring to Fig. 3, l have illustrated the element as cylindrical in cross section and have shown a shaft D provided with two grooves D and D respectively, each of which is provided with a rubber spring B, and located on the shaft, preferably midway between the springs It, is a projecting bead D which contacts with theelement l), and as the bowl I) rotates and tends to find its center of gravity, the bowl rocks on the bead D asit slightly shifts its position relative to the shaft 1), thereby bringing pressure to bear on the upper spring B ,on onc sideo'f the shaft D and on the om'iosite side of the spring B the head I) acting as a fulcruml By this means, the bowl E can rotate on the true axis of its mass and each of the spring rings B may be used to drive the same through frictional contact with the element D which is connected to the bowl E, either by friction or by any desired mechanical In starting the machine, acertainrelative movement will exist between the shaft C and bowl A until the inertia of the bowl is over come and it comes to the same speed as the shaft C.
The bowl is supported on the upper end of the shaft at C as illustrated. The means illustrated are very simple and accomplish the object of my inventi'on'most successfully.
Having thus described my invention, what I claim as new and desire to secure is:
1. In a centrifugal separating machine, a bowl having a. recess in its .bottom located at the center thcreo f, a driving shaft, the upper cnd'of which projects into said recess and supports said howl, one of said elements being provided with an annular head to serve as a fulcrum, and a ring of resilient material located above and below said annular head in contact with said shal'tmul servin; to drive said bowl. 1
2. In a centrifugal separating uuucbine, w bowl having a recess in its bollmn located at the center thereof, a removable clement titled in said recess and provided with a recess, a vertical shaft the upper end of which projects into said recess and carries said bowl;
groove located above and one below said fulcrum, a ring'of resilient material located in each of said grooves and serving as the medium through which said bowl is driven.
4. In a centrifugal separating machine, a bowl having a recess in its bottom located at the center thereof, a removable clement fitted a loosely in said recess and provided with a recess, a vertical shaft the upper end of wh ch projects into said recess and carries said bowl; said shaft having a projecting IlIlgOI bead which serves as a fulcrum, and
a ring of resilient material located above i andone beloi'v said fulcrum-and serving as the, medium through: wh1ch' .sa1d"', b0wl 1S drlven.
5. In a centrifugal separating machine, a
bowl having a recess in its bottom located at the center thereof, a removable element fitted in. said recess and provided with a recess, a vertical shaft the upper end of which .pro-
jects into said recess and carries said bowl;
said shaft having a projecting ring or head which serves as a fulcrum, and having-a groove located above and one below said f'ulcrum at equal distances therefrom,a rihg of resilient material located in each, of fsai dfio grooves and servlng as the medium through 1 which said bowl is driven.
