GENTRIFUGAL MACHINE Patented July 20, 1909.
Application filed November 1, 1904. Serial No. 230,915;
To all whom it may concern:
Be-it known that I, GEORGE N. GODDARD,
citizen of the United States, and resident of Newton Center, county of Middlesex, Massal 5 'ichu'setts, have invented certain new and useful Im rovements in Centrifugal Machines, of whic the following is a specification.
This invention relates to centrifugal machines and is intended to provide a simple and efficient construction whereby the perfect lubrication of such machines is secured I by the use of only a single shaft,-whilc at the same time making it possible to employ a direct connected motor for driving the machine, These objects are accomplished by a novel construction and arrangement of parts which will be fully described in this specificsi tion and ointed out inthe claims, reference being had for the sake of illustration to the accompanying drawings which show one of the modes of embodying my aforesaid inven- Fi ure 1 isii vertical sectional View showing t e novel construction and arrangement by which the machine is supported and driven. Fig. 2. is a plan view on the horizontal plane intersecting the oscillatory bracket and shaft immediately beneath the hanger in order to show the motor carrying yoke. Fig. 3 is a central. vertical section through the stationary hanger from which the machine is suspended.
Referring now to the drawings, a desighates the rotary shaftl -to the lower end of which is secured the basket or receptacle 7).
The shaft is supported by means of abearing head o having the general shape of an in- 5 verted cup, the shaft a being securely fas- 5 tened thereto by means of clamping nuts or other suitable means' This bearing head a is earned by a non-rotatable oscillatory which has a balland socket engagement with the stationary hanger (Z. Above the'bearing bracket having a spherically curved face 0 surface this oscillatory. bracket 0 is provided 1 with an annular channel provided with a 5 bearing ring or surface 0 which. supports the rotary head a. so as to permitits free rotaj tion.
In this instance 1 have shown bearing 5 balls 0 which are used as theanti riction medium between the rotatable head a and The bearing 5 This forms an annular oil reservoir which is closed by means of the lid or cover a which is provided with an upward extension 0 for engaging the upper end of the rotary shaft a so as to give an elongated bearing surface extending from the plane of the bearing ball c to the top of the extension 0 of the cover.
' to support a yoke or hanger f for carrying t field magnets or non-rotatable element of a direct connect-ed electric motor. 'As shown in the drawings thls downward extension 0 is of conical shape and at its lower end has a projecting flange c for sujpporting the hub f of the carrying yoke This carrying yoke for convenience in assembling may be made 111 two parts which may be put together to surround the downward extension 0 after which they are bolted together by means of the retaining bolts 0 as best shown in Fi e 2. to th: bracket 0 partakes fully of itsoscillation, the yoke and its carrying bracket being heldagainst rotation by means of any suitable contrivance such as the spiral springs f one end of which is hookedi-nto'eye bolts f 4 adjustably secured to the yoke f, while the other ends are secured to depending lugs or Ears (1 formed on the exterior of the hanger vents the rotation of the carrying yoke and hence of the non-rotatable motor element while at the same timesecuring simultaneous and equal oscillation of the two motor elements.
cooperatin elementf.
The hanger-d is made practically in the form of upper and lower rings d and (1 connected by vertical arms d. This notonly eonduces tolthe lightness of the construction but the spaces between the vertical arms (1 permit access 'to the interior parts without necessitating any disassembling of the ma- ,C llillO. The tension or" the springsf" may be varied by sel ing up the eye-boltsf which This arrangement and construction pr'e-.
This yoke f being rigidly secured The stationary motor elem ntf is secured directly to the rotary shaft a so as to lie in proper operative relationship to its middle of said arms.
are tapped into the flanges or ribs formed on the yoke f and are held against accidental movement by means of jam nuts f If desired, for the purpose of greater steadiness horizontal arms may be carried across the yoke f .both above and below the motor parts, to connect the 0 posite arms thereof in order to afford an ad itional hearing for the rotary shaft or for the rotating element of the motor. In such case suitable bearing boxes would be provided at the In machines of the larger size this would be efiective in giving greater rigidity between the rotatable and nonrotatablemembers.
Without attempting to set forth all the variations in the details of construction and arrangement that may be made in the practice of my invention, what I claim is 1. A centrifugal machine embracing in its construction, a rotary basket-carrying shaft, a bearing head secured to the upper part of said shaft to support the same, an oscillatory bracket by which said head is rotatably supported, said bracket being provided with a downwardly extending central, portion a yoke secured to said centraldownward ex tension, and a direct connected motor whose rotatable element is secured to the shaft and whose non-rotatable clementis secured to said yoke, substantially as described.
2. A direct connected electrically driven centrifugal machine embracing in its construction, a hanger whose bottom portion is formed with a central orifice, an oscillatory bracket having a ball and socket engagement with said hanger, said bracket being formed with a downward extension projecting through the central orifice in the hanger, means for securing the non-rotatable element of the motor to said downward extension for support, a rotary basket-carrying shaft, a bearing head to which said shaft is secured, said bearing head having rotatable engagement with the oscillatory bracket above its ball and socket connection with the hanger, the rotatable element of the motor being .directly connected to the rotary shaft in proper operative relationship to the nonrotatable member, substantially as de scribed.
A direct connected electrically driven centrifugal 'rnachine embracing in its 0011- struction, a rotary basket-carrying shaft, a supporting bearin head to which said shaft is secured, an osci latory supporting bracket provided with a spherically, curved bearing surface, said bracket having its upper portion provided with an annular bearlng for supporting the rotary bearing head, and having lts lower portion below its spherical bearing surface sion, said downward extension beyng prordvided with a downward eXten- Vided with a yoke for carrying the non-rotatable element of the motor, the rotatable element of said motor being directly connected to the rotary shaft, substantially as described.
4. A direct-connected electrically-driven centrifugal machine embracing in its con struction, a fixed hanger formed with a spherical seat or socket provided with a central aperture, an oscillatory bracket formed intermediate of its ends with a s herical bearing surface adapted to be seate in said spherical socket, a basket-carryi'n shaft susended to hang through a vertica axial bore ormed in said bracket and having a basket secured to its lower end, abearing head rigidly connected with the upper end of said basket shaft and supported upon a rotary bearing carried by said bracket, an electric motor whose rotating member is.secured to said basket shaft and whose field magnets are rigidly secured to the lower portion of the oscillatory bracket beneath its seat, substantially as described.
