IMPROVEMENT IN PRESSUREATTACHMENTS FOR AIR-PUMPS.
Specification forming part of Letters Patent No. l 84.456., dated November 2,1, 1876; application led 'Juiy 1'2, 1876.
To all whom it may concern Be it known that I, DAVID E. BANGS, of Medford, county of Middlesex, State of Massachusetts, have invented certain new and useful Improvements in a Regulating Attachment for Air Pumps, of which the following is a specification:
This invention relates to certain improvements in a regulating attachment for airpumps, whereby a more even dow of air may be obtained, and is especially designed to prevent any jar or sudden change that might arise from the uneven working of the pump. It consists of a valve working within an eX- pansion-cylinder, and attached to the outletpipe of the pump, and so arranged as to be operated by the action'of the air itself, closing when a certain pressure has been reached, and opening when the pressure is reduced, thus working automatically to keep an even pressure in the pipe.
In the drawing, Figure 1 is an elevation of my invention, with the outlet-case broken away, to show the expansion-cylinder Within. Fig. 2 is a vertical section of the same.
A is the outer case; B, the expansionchamber, C, the diaphragm. a is the inletpipe; b, the outlet-pipe; c, the valve attached to the lever d. e is the chain connecting the lever With the movable diaphragm C.
The operation of my invention is thus described: Air coming from the pump enters ,to allow the diaphragm to fall.
In the drawing the diaphragm is shown in its highest position, with the valve closed. The diaphragm may be weighted to give any pressure required.
Having thus describedmy invention, what I claim as new, and desire to secure by Letters Patent, is-
The cylinder A, inlet-pipe a, outlet-pipe b, valve c, with lever d, and chain e, operating in combination with the movable diaphragm C, in the manner and for the purpose Specied.
