Spray Gun

William R. Brown |
Chicago, Cook County, IL |
Abstract:
An object of the invention is to provide self-regulating means which, regardless of the fact that a higher than necessary air pressure may be delivered to the device, the pressure will automatically be cut down in the device so that the same operates at some predetermined lower pressure. Another object of the invention is to provide adjustable means for determining the pressure utilized in the device, such as ten, fifteen or twenty pounds, even though the source of air pressure may be very much higher.
Claim:
n a hand spray gun, having a handle for holding the gun, a valve between the supply pressure and its outlet, and means for controlling and regulating the atomizing pressure comprising finger controlled means for opening said valve and pressure actuated means operable by the atomizing pressure for variably closing the valve, said finger controlled means being mounted convenient to the handle so that it can be controlled by the same hand which holds the gun. |

Original application filed 11 Jan., 1943. Divided and this application filed 07 Apr., 1944. This application is a division of my co-pending application, Serial No. 472,020, filed January 11, 1943 which is now abandoned.
Abstract:
n object of this invention-is to provide a new and improved valve structure for the control of a pneumatic tool and arranged for foot actuation, so that both of the operator's hands are free for other work.
Claim:
In a foot controller for a pressure fluid actuated device, the combination of a base, a valve casing mounted on said base, said casing having therein a valve operable by linear motion to the operating positions, means comprising a resilient member biasing said valve to one of said positions, an actuating member movable linearly an adapted to effect movement of the valve again: the normal biasing force to the other of said or operating positions, said actuating member having a cam surface, an operating member providing a protecting cover for the valve casing and supported for rocking movement, and said operating member having a pair of cam surfaces there on in cooperative relation with the cam surface of said actuating member, one of the cam surfaces on said operating member being adapted to move said actuating member to effect operation of the valve, and the other of said cam surfaces on said operating member being adapted to hold said actuating member in a fixed position. |
