CREAM-REGULATING DEVICE FOR SEPARATORS.
SPECIFICATION forming part of Letters Patent No. 733,273, dated July 7, 1903.
Application filed April 14, 1908.
To (all whom it may concern:
Be it known that 1, WILLIAM 7. PRICE, a citizen of the United States, residing at Poughkeepsie, county of Dutchess, and State of New York, have invented a new and useful Improvement in Cream-Regulating Devices for Separators, of which the following is a full,
clear, and exact description, reference being had to the accompanying drawings, which to form a part of this specification.
The object of my invention is to regulate and vary during the revolution of the bowl the density of the cream discharge. I accomplish this object by the mechanism herein-' after described.
In the drawings, Figure 1 is a side elevation of my separator with a'portion of the cover broken away, showing the ring in section and the adjusting-screw. Fig. 2 is an enlarged section on line 2 2, Fig. 1. Fig. 3' is an enlarged inside view of the ring and wings. Fig. at is a section on line 4 4, Fig. 3. Figs. 5 and 6 are perspective views of the wings. Fig. 7 is an enlarged section of rollers and end of adjusting-rod.
A is the case of a centrifugal separator; B, the bowl; I), the neck of the bowl; O,the feedcup.
D is the skim-milk outlet, and E the creamoutlet.
Surrounding the neck of the bowl so as to make a sliding fit is the ring F, having the flange f. This ring F is placed upon the neck of the bowl in such position that the fiangef is above the top of the neck of the bowl. In the side of the ring F is the elongated orifice or slot f. Projecting outward through this orifice is the tube f having secured to it at a point on the inner side of the ring a wing G, having angular faces g g. The wall of the inner end of the tube f is cut away, forming orifice the inner end of which is flared outwardly by inclined ends 9 Surrounding this tube f within the ring is a tube f having raised above its outer end a wing G, corresponding to, but projecting in opposite directions from, the wing G. The inner end of the tube f is cut away to correspond with the inner end of tube f forming an orifice g with inclined ends 9 In one position, as hereinafter described, the orifices g" and g Serial N0.l52,503- (No model.) 1
and the inclined ends g and g coincide. The tubes f and f are slidably fitted one upon the other. As may be seen, by sliding one tube upon the other through the medium of the wings the orifices g and g may be brought from a position of coincidence to positions where the orifice in the tube f is more or less cut off. The wings G and G are in alinement with and on the same level with each other, and thus the limit of motion is obtained by the inner ends striking in the movement in either direction. This is so adjusted that it occurs before there has been suficient movement to cause the inclined ends g to pass beyond the inclined ends 9 and thus entirely inclose the orifices g and g. The orificed ends g and g of the tubes f and f i are inserted within the bowl through the creamoutlet E in the bowl. As may be seen, by moving the wings G G, so as to more or lessclose the orifices g and 9 the density of the cream delivered from the bowl will be varied. I accomplish this movement of the wings while the bowl is rotating in the following manner: The outer end of the tube f 2 extends outwardly through the orifice or slot f, as hereinbefore described. The inner surface of the ring is cut away at H H to form seats for the wings G G, re- 86 spectively, the cut-away portions being bound by upper and lower concentric curved portions h and h, the width of the cut-away portions being equal to the width of the wings G G. The tubes and wings are placed in position so that the orificed portions g and g are on the lower surfaces of the tubes. As may be seen, the vertical positions of the tubes f and f are fixed. It may also be seen that by moving the ring upwardly the ori- 9o fices g and g are enlarged. By moving the ring downwardly the orifices g and g are contracted. I move this ring up and down,when the bowl is rotated by the following mechanism: 5
I is a rod having at its lower end the projectin g rollers '2? t the space between which is slightly greater than the thickness of the fiangefof the ring F. The upper portion of this rod has the thread i cut thereon and the mo internally threaded nut 2'. Above and below this nut i" and surrounding the rod are the bearings J, secured to the feed-cup D, Any other non-rotatable portion of the machine will answer as well as the feed-cup D to which to secure the bearings D. Near the upper end of the rod I is the projecting rod K. The position of the parts as shown is such that by moving the rod K the rollers i and i will be brought respectively above and below the flangef. 'When in this position, by turning the nut 2 in one direction the rod I is elevated, and through the medium of the roller '5 the ring F is elevated and the density of the cream decreased, and when the nut is turned in the other direction through the medium of roller 7; the ring F is depressed and the density of the cream increased. As the ring F is rotating with the bowl and thus rapidly, the action of rollers 11 or i is practically upon the whole circumference of the flangef of ring F.
Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is-.
