HENRY W. PLEISTER, OF WESTIEIELD, NEW JERSEY, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO HENRY B. NEWHALL CORPORATION, OF GARWOOD, NEW JERSEY, A COR- PORATION OF NEW JERSEY.
OSCILLATING CENTRIFUGAL MACHINE.
Application filed August 11, 1926. Serial No. 128,624.
This invention relates to centrifugal machines and more particularly to machines and methods for removing excess molten metal from articles being coated.
The invention relates particularly to modifications of the method and apparatus described in my United States Patent No. 1,580,614, issued March 24, 1925.
One object of the invention is to provide a simple machine and method of this kind for subjecting articles to centrifugal force in varying directions.
Another object of the invention is to provide an apparatus of this kind entirely free of planetary gears.
Another object of the invention is to provide a method and apparatus of this kind for revolving a round basket in such a manner that loose articles therein tend to move circumferentially around the basket.
Other objects of the invention are to improve generally the economy, simplicity and efficiency of such methods and apparatus and to provide an apparatus of this kind which is economical, durable and reliable in operation, and economical to manufacture.
Still other objects of the invention will appear as the description proceeds; and while herein details of the invention are described and claimed, the invention is not limited to these, since many and various changes may be made without departing from the scope of the invention as claimed in the broader claims.
The inventive features for the accomplish ment of these and other objects are shown herein in connection with two improved machines. each of which, briefly stated includes a vertical rotary shaft carrying fast thereon a beam having an arm provided with a supporting ring in which is loosely supported a perforated basket provided with a handle-like member fast thereon and engaged at the outer end portion by suitable means permitting sliding movement of the handle member and holding it against revolution and thereby the basket against complete rotation.
In the accompanying drawing, showing by way of example, two of many possible 50 embodiments of the invention,
Fig. 1 is a central vertical sectional view, partly in elevation, showing one form of the machine;
Fig. 2 is a fragmental end elevation of 55 a detail;
Fig. 3 is a somewhat diagrammatic horizontal sectional view, partly in plan, showing paths of articles in the machine;
Fig. 4 is a central vertical sectional view, partly in elevation, showing another form of the machine;
Fig. 5 shows a section taken on the line 5-5 of Fig. 4, looking in the direction of the arrow of said line; and
Fig. 6 is a longitudinal vertical sectional View, partly in plan, the section being taken on the line 6-6 of Fig. 4, looking in the direction of the arrow of said line.
The various parts of the machine of Fig. 1 are shown carried on a platform base 10 having thereon a pedestal 11 having vertical lower step, thrust and upper annular bearings therein receiving a vertical shaft 15 carrying a horizontal beam 16 intermediately secured fast on the upper end of said shaft and having one arm formed into counterpoise rod 17 carrying an adjustably disposed weight 18 and the other arm provided with a large axially vertical supporting ring 20 entirely eccentric to said shaft and supporting a bearing ring 21 rotatably received therein and provided with upper and lower exterior retaining flanges 22 and 28.
A downwardly disposed basket 25 loosely received in said opening has a perforated bottom and perforated sides 26 for the passage of spelter, the sides being vertical or at least sutliciently steep to prevent the discharge of articles when the shaft is rotated and the basket revolved. The upper edge portion of the basket is provided with a, heavy strengthening band 27 loosely received in said bearing ring and provided 95 with an upper lateral flange 28 for supporting the basket on bearing ring.
A tall pedestal on said platform base a distance from said bearing pedestal is provided in its upper end with a vertical bearing bore supporting a T-shaped bearing member 32 provided with a lower stem 33 rotatable in said bore. Said member is also provided with a transverse slide bearing bore or groove 34 (Fig. 2) in which is received a long, slightly upwardly offset horizontal ggdlal handle 35 mounted fast on said band A miter gear 38 on said main shaft 15 between the pedestal and beam meshes with a similar gear 39 fast on a horizontal shaft 40 mounted in brackets 41,42 on said base beneath the path of said basket. Said shaft 40 is provided with an outer-pulley 43, and an intermediate clutch 44. A motor disposed a distance from said base and having its shaft 46 horizontal is provided with a drive pulley 47 receiving a belt 48 disposed around said pulley 43 for rotating said horizontal and vertical shafts 40 and 15 for revolving the basket 25.
A series of brackets 49 disposed around said bearing pedestal carry a drum or spelter baflle 50 disposed around the orbit of said basket to stop spelter thrown through the sides thereof. Said drum is provided with "an upwardly opening cutout opening 51 near the slide bearing member to receive the handle 35. A quickl removable cover 52 is disposed over the rum.
An upwardly pointing cone-shaped deflector 55 mounted on said platform base around the bearing pedestal and said gears to receive the spelter from the basket and drum is provided with an outlet for said horizontal shaft 40 in which is disposed a protecting bushin 57 receiving said shaft.
In t e form of invention of Fig.4, the vertical rotary shaft 15 driven by means similar to that of Fig. 1 and the horizontal beam 66 intermediately secured fast on said shaft has also one arm provided with a large axially vertically supporting ring 70 eccentrio to the shaft rotatably receiving a flanged bearing ring 71 in turn receiving a downwardly disposed perforated basket 7 5 provided on its upper edge portion with a flanged band 78 loosely supported in said bearlng ring. In this form, however, the handle member 85 is differently supported and controlled, as will be explained.
A pair of tall uprights 90 on opposite sides of the path of said basket carry a bar 91 carrying a slideway 92 (Fig. 5) longer than the diameter of the orbit of the basket, secured on the under face of said bar and comprising a channel member 93 and a pair of inwardly projecting rails 94 slidably receiving lateral grooves 95 of a slide block 96. 1
As the basket-is rigidly connected to the handle 35', and the handle held by the sleeve 32 from revolving entirely around the shaft 15. and never revolves around the axis of the pedestal 30, as shown in Fig. 3, the basket and the articles, if packed therein, never make a complete absolute rotation, that is, they never make a complete rotation about their own axes relative to the base of the machine, but do make an oscillatory or swinging movement about the axis of the pedestal 30. If any article held p'ackedin the basket points toward the pedestal, it is obvious that it will continue to do so and will therefore not rotate, though it does revolve about the shaft 15. This is contrary-to the action of the usual centrifuge or the planetary centrifuge in that these latter articles not only revolve about the axis of the main shaft, but in so doing make absolute rotation about their own axes.
The horizontal handle-like member 85 is here shown as flat slightly upwardly offset and secured fast on the ring 71 radial to the axis thereof and with its outer end pivoted to a bolt 97 on said slide block 96. The drum or battle 100 disposed around the orbit of the basket is provided with a pair of upwardly opening cutout openings 101 to receive said bar and slideway. The cover 102 is disposed on the drum above the bar 91.
The purpose of the invention is to impart to the articles after immersion in the galvanizin kettle a centrifugal motion somewhat simi ar to that described in my above named patent except, that in the new device herein the eccentric basket 25 will revolve about the main shaft 15 without a continuous rotation about its own axis, remaining approximately parallel to one vertical plane at all times, with a slight oscillation first in one direction and next in the other direction about its own axis as it passes around the main shaft, the oscillation being insutficientto cause a complete rotation in one direction.
As the beam 16 is rotated about the main shaft 15 and the long handle 35 of the basket held substantially in a constant direction, the basket will be caused torevolve around the main shaft 15 and at the same time to oscillate through the action of the handle slidably held by the member 32.
Articles placed in the basket thus mounted,fafter having been preliminarily treated in the galvanizing process as described in my Patent N 0. 1,530,614 will be subjected to a motion whereby the lines of centrifugal force radiating from the main shaft will act upon the articles in continually changing direction relative to the article being thus treated.
While no material change in the influence of the lines of centrifugal force will be protaken by the articles when the basket is filled and when only a few articles are placed in it.
In order to explain this difference I will first describe the path or orbit O of any fixed point in the basket, as when the basket is full, selecting for convenience point A (Fig. 3) which is located degrees from the point at which the handle is attached.
The basket is shown in four positions around the shaft 15 which positions of the basket are marked 1, 2, 3 and 4. In position 1 point A is practically at its greatest distance from the shaft 15, as it reaches position 2, the point A has somewhat approached the shaft; when the basket has reached position 3. the point A has almost attained its nearest approach to the shaft; at position 4 it has increased its distance from the shaft. In the various positions the influence of the centrifugal force upon an article fixed at A will cause changing lines of centrifugal force passing through every sub-division of the points of the compass, and the article will travel through a path represented by the ellipsoid orbit 0.
If, however, the articles are loosely sprinkled in the basket so that they may shift or fly or roll about in the basket they will be influenced by the lines of centrifugal force radiating from the axis of the shaft 15 to move from one point in the basket to another toward the point farthest removed from the shaft. This will cause the article marked X always to take a position in the basket as remote as possible from the shaft 15 and move about 90 degrees around the circumference of the basket as shown at X every time the basket moves 90 degrees around its orbit or path P.
The path P of Fig. 6 is practically the same as the path P of Fig. 3; but the orbit 0 because of the shortness of the handlelike member 85 is slightly more pointed than the orbit O.
lVh-ether one or a few articles are placed in the basket the rolling motion around the edge of. the basket will cause a continuous change of the lines of centrifugal force in relation to the article being coated though mssiblv to a greater degree and with more frequent changes than when the article is one of many which fill the basket, or a combination of the twodepending upon how nearly the basket is filled. The agitation of the articles thus caused will serve to prevent their freezing one to the other when in a mass.
The use of the long handle 35 to the basket 15 makes it convenient for the galvanizer to use it as a lever on the edge of the pot as a fulcrum for moving the basket around in the molten zinc; and by means of a hook conveniently suspended between the end of the kettle and the centrifugal machine the handle can be used as a lever with the hook as a fulcrum for swinging the basket from the kettle into the machine. However, the invention is not limited to the long handle to accomplish the oscillatory motion, since this motion can be given just as well to the basket 75 which may have a shorthandle or bail.

1. A method of removing excess molten metal from articles, said method comprising moving the articles in a curved path; and subjecting the article to oscillation while being thus moved.
