UNITED STATES PATENT lPrion..
ALBERT L. REINMANN, OF PITTSBURG, PENNSYLVANIA.
VALVE-CASE FOR MERCURIAL AIR-PUMPS.
SPECIFICATION forming part of Letters Patent No. 331,546, dated December l, 1885.
Application liled September 24, 1885. -Serial No. 177,967. (No model.)
To a/ZZ whom it may concern,.-
Be it known that I, ALBERT L. REINMANN,
residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in Valve-Cases for Mercurial Air Pumps, of which improvements the following is a speciiication.
In the accompanying drawings,which make part of this specification, Figure l is a sectional elevation of a length of pipe forming part of a mercurial air -pump, said pipe having valvechambers for the reception of iioat or automatically-acting valves. Fig. 2 is a similar view showing certain moditications in the shape of the valve-chamber and the contained valve. Figs. 3, 4, and 5 are views showing diiferentforms of valves in elevation.
In making these valve-chambers it is customary to enlarge a portion of the pipe in which said chambers are to be formed, and then after inserting the valve to draw down the pipe at each end or side of the enlargement to the normal or desired size of the pipe, thus inclosing the valve in a chamber having walls integral with the pipe at each side thereof. This. construction is objectionable,for the reason that ii'the contained valve is broken or injured in any way it is necessary to remove all that portion of the pipe in which the valve-chamber is located, and substitute therefor an entirely new length of pipe, thus adding considerably to the cost of oper- -ating the pump.
The object of my invention is to so construct such portions of mercurial pumps as include chambers in their length as to permit of the ready insertion and renewal of the valves without destroying the chamber in which the valve is located; and to this end my invention consists in the construction of parts, all as more fully hereinafter described and claimed.
In carrying out my invention the pipe is made in sections l, 2, and 3, as shown, the length of such sections being determined by the location of the valve-chambers. The adjacent ends of two adjoining sections are then enlarged, as at 4, 5, 6, and 7, for the reception of the valve 8, the pipe at the ends of the enlargements being contracted, as shown. The outer ends of the enlargements of two sections are made of such relative diameters that the end of one will t within the end of the other, the ends being correspondingly tapered in order that they may be ground together, thereby making a hermetic joint.
In a mercurial pump having the valvechamber constructed as described the valves are not put in place until the parts of the pump are placed together, thus avoiding any liability of breaking the valves in handling, the pipe-sections having the valve-chambers integral therewith.
Another import-ant advantage arising from the above described construction of valvecase is the possibility of inserting atool within the enlargement for the purpose of properly shaping the Valve-seats at the ends of the enlarged portions, Aand also of properly shaping and sizing the enlarged cavity to suit the kind of valve to be inserted in the chamber. rlhe valves used in these chambers are varied as to shape and size, as shown, and are adapted to close the opening at either end of the chamber, as desired. y
The valves employed in closing the lower end of the valve-chamber are preferably made hollow for the reception of a small quantity of mercury, which, from its weightwill seat the valve before all the mercury can escape from the valve-chamber, the mercury caught in the chamber by the seating of the valve serving as a seal.
The desired amount of mercury may be sealed in the hollow valves, if desired; or an opening, 9, may be formed in the side of the valve, the mercury filling the valve through said opening as it lls the valve-chamber.
It will be noticed that in the above-described construction of valve-case the valve and valve-seat may be ground together for the purpose of 'producing a perfeetlytight joint combination with a valve located Within said case, substantially as set forth. 1o
In testimony whereof I have hereunto set between them, and that the case can be easily taken apart for the purpose of cleaning the oase-Valve.
I claim herein as my inventionmy hand. 5 In a mereurial air-pump, a va1ve-ease oon- ALBERT L. REINMANN.
