Abstract
Abstract A cleaning machine including a front opening cabinet or housing having an upper cleaning chamber and a lower fluid reservoir and a fluid pumping system for transferring fluid from the reservoir to the cleaning chamber through a system of fluid conduits. Operation of the pumping system simultaneously sprays hot cleaning fluid over the objects to be cleaned, rotates a turntable supporting the objects, and operates a latch mechanism to free the turntable for rotation from a predetermined working position. Sediment collection devices may be disposed in the reservoir.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
80 words
In a heavy duty, industrial cleaning apparatus of the type having a cleaning chamber, a cleaning fluid reservoir, and a pumping system to transfer fluid under pressure from the reservoir to the cleaning chamber; a turntable rotatably mounted in the cleaning chamber for supporting objects to be cleaned during a cleaning operation, and latch means automatically operable in response to a change in fluid pressure due to deactivation of the pumping system for stopping the turntable in a predetermined position.
Claim 2
Dependent Claim
80 words
In a heavy duty, industrial cleaning apparatus of the type having a cleaning chamber, a cleaning fluid reservoir, and a pumping system to transfer fluid under pressure from the reservoir to the cleaning chamber; a turntable rotatably mounted in the cleaning chamber for supporting objects to be cleaned during a cleaning operation, and latch means automatically operable in response to a change in fluid pressure due to deactivation of the pumping system for stopping the turntable in a predetermined position.
Claim 3
Dependent Claim
55 words
Apparatus as defined in claim 1 wherein the latch means includes respective interfering stop members, one such member being mounted on the turntable and the other being disposed in the chamber, and actuator means for displacing said other member out of interfering relation with the one member in response to actuation of the pump means.
Claim 4
Dependent Claim
50 words
Apparatus as defined in claim 2 wherein the actuator means includes a displaceable plunger carrying said other member, bias means to urge the plunger into a first position wherein the stop members interfere, the actuator means being responsive to fluid pressure to displace the plunger away from said first position.
Claim 5
Dependent Claim
21 words
Apparatus as defined in claim 3 including means to prevent rebound of said one stop member from said other stop member.
Claim 6
Dependent Claim
16 words
Apparatus as defined in claim 4 wherein the means to prevent rebound includes a permanent magnet.
Claim 7
Dependent Claim
85 words
Apparatus as defined in claim 1 including a housing defining the cleaning chamber, a panel pivotally connected to the housing for rotation about a horizontal axis proximate the lower boundary of the panel to provide access to the chamber and to provide a horizontal surface exteriorly adjacent the chamber when lowered, first track means on the interior surface of the panel, and second track means on the turntable, the first and second track means being contiguously aligned when the turntable is in the predetermined position.
Claim 8
Dependent Claim
22 words
Apparatus as defined in claim 6 wherein the first and second track means include spaced rail members for supporting a wheeled carriage.
Claim 9
Dependent Claim
25 words
Apparatus as defined in claim 7 wherein the rail members of the first and second track means are provided with angularly complementary mating end surfaces.
Claim 10
Dependent Claim
21 words
Apparatus as defined in claim 8 including drive means responsive to the actuation of the pumping system to rotate the turntable.
Claim 11
Dependent Claim
30 words
Apparatus as defined in claim 9 wherein the drive means includes at least one nozzle operatively connected to the pumping system to direct fluid from the reservoir against the turntable.
Claim 12
Dependent Claim
27 words
Apparatus as defined in claim 10 including radial fins on the turntable and reactive with the fluid from the nozzle to impel the turntable by fluid reaction.
Claim 13
Dependent Claim
30 words
Apparatus as defined in claim 11 including at least one paddle operatively connected to the turntable for rotation therewith and extending into the reservoir to retard rotation of the turntable.
Claim 14
Dependent Claim
21 words
Apparatus as defined in claim 11 including a baffle disposed beneath the turntable and separating the cleaning compartment from the reservoir.
Claim 15
Dependent Claim
37 words
Apparatus as defined in claim 13 including a container disposed in the reservoir for catching fluid draining from the baffle, the container having at least one perforated wall portion for straining fluid released back into the reservoir.
Claim 16
Dependent Claim
46 words
Apparatus as defined in claim 14 wherein the housing is provided with a forwardly extending lower compartment defining the reservoir, an opening at the upper boundary of the compartment, a cover on the opening, the container being disposed in the compartment for removal through the opening.
Claim 17
Dependent Claim
28 words
Apparatus as defined in claim 11 including at least one shallow pan disposed on the floor of the reservoir to catch sediment and like matter entering the reservoir.
Claim 18
Dependent Claim
22 words
Apparatus as defined in claim 16 including a plurality of said pans, each pan having meaNs interlinking it with an adjacent pan.
Claim 19
Dependent Claim
29 words
Apparatus as defined in claim 9 wherein the latch means is operatively connected to the pumping system to be actuated in response to the deactuation of the pumping system.
Claim 20
Dependent Claim
55 words
Apparatus as defined in claim 18 wherein the latch means includes respective interfering stop members, one such member being mounted on the turntable and the other being disposed in the chamber, and actuator means for displacing said other member out of interfering relation with the one member in response to actuation of the pump means.
Claim 21
Dependent Claim
50 words
Apparatus as defined in claim 19 wherein the actuator means includes a displaceable plunger carrying said other member, bias means to urge the plunger into a first position wherein the stop members interfere, the actuator means being responsive to fluid pressure to displace the plunger away from said first position.
Claim 22
Dependent Claim
21 words
Apparatus as defined in claim 20 including means to prevent rebound of said one stop member from said other stop member.
Claim 23
Dependent Claim
16 words
Apparatus as defined in claim 21 wherein the means to prevent rebound includes a permanent magnet.
Claim 24
Dependent Claim
61 words
Cleaning apparatus comprising a housing having a cleaning chamber and a reservoir chamber, a turntable in the cleaning chamber for receiving parts to be cleaned, a latch for maintaining the turntable in a given position, and a selectively actuated fluid pressure system for transferring cleaning fluid from the reservoir chamber to the cleaning chamber and simultaneously unlatching and rotating the turntable.
Claim 25
Dependent Claim
61 words
Cleaning apparatus comprising a housing having a cleaning chamber and a reservoir chamber, a turntable in the cleaning chamber for receiving parts to be cleaned, a latch for maintaining the turntable in a given position, and a selectively actuated fluid pressure system for transferring cleaning fluid from the reservoir chamber to the cleaning chamber and simultaneously unlatching and rotating the turntable.
