To ALL WHOM 1T MAY c0NcERN:
Be it known that I, ELIAS S. HUTCHINSDN, ofthe city and county of Baltimore, and State of Maryland, have invented a new useful Automatic Check-Valve for Liquid-Meters `and other purposesg. and I do hereby declare the following to be a full, clear, and exact description ot' the same, reference being had to the accompanying drawing, which is made a. part of this specification, and which represents asectional view of a distilling apparatus embodying my invention.
This invention consists in the application, to 'a pump pipe, of a thermo-dynamic valve, governed by an expansible rod, and employed to seal or close the pipe when the apparatus is in its cold or inoperative condition. Thus, as it is only necessary, in the legitimate operations of a sti1l,-to pump into thedoubler while the apparatus is heated, Ivpropose toarrange a valve in the pump lpipe or discharging pipe, said valve to be securely closed while the doubler'is cold and not in operation, and allowed to open when thedoubler is heated, by the contraction and expansion of a brass or other suitable metallic rod or tube, as hereinafter-explained. By thus closing the valve it becomes impracticableto perpetrate fraud by pumping vhigh wine back into the doubler, when the apparatus is cold, so as to add to the amount recorded by the credit-meter oi' the s'till.
l A represents a metallic valve, having a. seat, C, within theinlet pipe DV leading from the pump to the doubler or distilling vessel E. As the doubler cools the enclosed metallic rod F contracts, and its free extremityf being bent downward, as represented, assumes a position in contact with the valve A, which is thereby held snugly to the seat C, thus etfectually closing communication with the stilllthrough the pipe D While the apparatus is in its cooler inoperative condition. As the doubler becomes heated, the' rod F expands, and its extremityf receives sulcient motion to place it out of the way of interference with the upward motion of` the valve A, which opens freely in the direction of the incoming current, when the apparatus is in its heated or operative condition. The valve .A may,l if desired, be applied to the pipe G, through which the liquid is introduced for the first operation. p
I do not wish to be understood as confining the application of the valve to a doubler, as it maybe employed in other pump pipes without departing from the essential principles of the invention. v
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The application to a pump pipe of a thermo-dynamic valve, substantially as described.
To the above specification of my automatic check-valve for liquid-meters I have signed my hand this second day of May, 1867.
ELIAS S. HUTCHINSON.
