Abstract
Abstract A centrifugal dryer for drying small machine parts. The dryer features means such as an access door and a biased ramp leading thereto to facilitate the loading and unloading of a basket containing the parts into and out of the dryer. In addition, the drying process is expedited by utilization of heated air driven directly from a heater above the basket bearing the part through to the bottom of the work basket thereby minimizing duct work.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
123 words
A centrifugal dryer for spinning machined parts at a high rotational velocity to dry the said machine parts, said dryer comprising a base section, said base section supporting a cabinet section rising from said base section, perforated basket means for holding said machine parts, spinner assembly means located within said cabinet for spinning said basket, motor means mounted on said base section for supplying power necessary to spin said spinner assembly, clamping means for clamping said basket to said spinner assembly, control means for selectively starting or stopping said motor means, coupling means for coupling said motor to said spinner assembly, and access opening means in the side wall of said cabinet section for loading and unloading said basket on said spinner assembly.
Claim 2
Dependent Claim
123 words
A centrifugal dryer for spinning machined parts at a high rotational velocity to dry the said machine parts, said dryer comprising a base section, said base section supporting a cabinet section rising from said base section, perforated basket means for holding said machine parts, spinner assembly means located within said cabinet for spinning said basket, motor means mounted on said base section for supplying power necessary to spin said spinner assembly, clamping means for clamping said basket to said spinner assembly, control means for selectively starting or stopping said motor means, coupling means for coupling said motor to said spinner assembly, and access opening means in the side wall of said cabinet section for loading and unloading said basket on said spinner assembly.
Claim 3
Dependent Claim
44 words
The centrifugal dryer of claim 1 wherein said base means includes a biased platform section, said biased platform section being adjacent to said access opening, whereby said basket can be slid up said biased platform section through said opening onto said spinner assembly means.
Claim 4
Dependent Claim
53 words
The centrifugal dryer of claim 2 wherein door means are provided for covering said access opening, vertical hinge means for coupling said door means to said side wall, latch means for selectively locking said door means, and means for preventing the operation of said spinning assembly when said door means is not latched.
Claim 5
Dependent Claim
43 words
The centrifugal dryer of claim 3 wherein said spinning assembly means comprises a spinning platform, post means on said platform for abutting said basket when said basket is properly placed on said platform, and clamp means for locking said basket onto said platform.
Claim 6
Dependent Claim
31 words
The centrifugal dryer of claim 4 wherein said post means comprises three spaced apart angle irons vertically mounted to said platform and arranged to describe the outer contour of said basket.
Claim 7
Dependent Claim
68 words
The centrifugal dryer of claim 5 wherein said clamp comprises hinge means securred to one of said angle irons, clamp body means conforming to the outer periphery of said basket attached to said clamp means, and means for attaching the end of said clamp body means which is not connected to said hinge to an adjacent one of said angle irons to thereby lock said basket in place.
Claim 8
Dependent Claim
33 words
The centrifugal dryer of claim 3 wherein said motor means includes automatic brake means electrically operated to brake the rotation of said motor when said control means is operated to stop said motor.
Claim 9
Dependent Claim
60 words
The centrifugal dryer of claim 7 wherein said coupling means includes first wheel means attached to the shaft of said motor, second wheel means attached to a drive shaft on said spinning platform, belt means coupling said first wheel to said second wheel whereby the operation of said motor causes said drive shaft to be rotated to rotate said platform.
Claim 10
Dependent Claim
36 words
The centrifugal dryer of claim 8 wherein fan means are coupled to said drive shaft, said cabinet having a screened opening at the top thereof, whereby the rotation of said fan draws air through said cabinet.
Claim 11
Dependent Claim
36 words
The centrifugal dryer of claim 9 wherein the top section of said cabinet is immobile, and heater means mounted to the top section adjacent said screened opening whereby said fan draws heated air through said cabinet.
