IMPROVEMENT IN DRY GAS-REGULATORS.v
TO ALL WHOM IT MAY CONCERN:
Be it known that I, JOHN B. HorrMAN, of Philadelphia, Pennsylvania, have invented an Improvement in i Gas-Regulators; and I do hereby declare the following to bc a full, clear, and exact description of the same.
My invention consists of a bellows-like recciver applied to a gasregulator, substantially as described hereafter, so as to obviate the necessity of using the fiuids which lave been heretofore employed, and which have a tendency to corrode the metal parts of a regulator.
The invention further consists of a ecrtain chaubor, with a tight detachahle cap arranged on the top of the regulator, in the manner and for the purpose described hereafter.
In order to enable others skilled in the art to make and apply my invention, I will now proceed to describe its construction and operation, reference being had to the accompanying drawing, which forms a part of this specification, and in which- Figures 1 and 2 are vertical Sections of my improved 'gas-regulator, with tho recciver'and valve in different positions, an'd Y i Figure 3 a'plan view;
Similar letters refer to similar parts throughout the several views.
Ais the cuter casing of the regulator, near the lower end of which is a horizontal partition, d, the space between the latter and the bottom plate B being divided by a vertical partition, a, into two compartnents, C D, the formar communicating with a n outlet or distributing-pipe, E, and the latter with an inlet-pipe, F. At or about the centre of the casing A, and secured to the partition d, is a cylinder, G, which communicates through an opening, b, with the compartment D, and at the top of this cylinder is a screw-cap, e, having an opening, y, through which passes a conical valve,f, suspcnded from the top c ofa receiver, H. The body of this receiver is of leathcr, or other fiexihle material, impervious to gas, is socured at its l'ower edge to the partition d), and is corrugated, as shown in the d'awing, so that it may be exterded und contractcd vertically, in the same manner as bellows of a similar form. The receiver communieates through an opening, bf, with the chamber C, and from the top ofthe receiver projects a rod, through the top of the casing A, and into a chamber, I, on the top of the said casing, the chamber being covvered by a perfectly tight but detachable cover or cap, j,. and on a disk, k, secured to the rod z', within the chamber, rest one or more Weights, x. Near the bottom of the easing A are two tubes, un, one communieating with the compartment C, and the other with the compartment D, and each tube has a screw-cap at its outer end. The pipe F communicates with the street-main, and conducte the gas from the latter to the compartment D, from which it passes through the tube G to the receiver H, and thenoe through the opening' 5' and compartment C to the distributing-pipe E. I
Such a weight is placed upon the disk k that when the pressure within the receiver is in excess of the amount reqircd, the receiver will be extendcd, and the valve f will be raised until the opening y is so con= tracted, and the fiow of gas is so retarded, that the pressure within the receiver will be reduced to the extent required. In like manner, a decrease of the pressure within the receiver will be followed by a contraction of the latter, the descent of the valve, and such an enlargement of the opening y as will permit the gas to pass into the receiver as rapidly as is necessary to restore the pressure in the latter. By increasing or reduciug the `weight upon the disk k, any desired pressure may be maintaincd within the outlet or distributingpipes, this alteratio n of the weights and regulation of the pressure being eti'ected without interfering with the continuous fiow of gas through the regulator.
Any matter which condenses within the regulator, cr within thespipes E F, will fiow into the compartments C D, the interruption of the fiow of gas in consequence of the stoppage of the passages being thus prevented. The condensed material may be withdrawn from the compartments O D at any time, by removing the caps on the tubes rn n.
By the use ofa bellows-like receiver, as above described, the corrosion of parts of the regulator which occurs when-fluids are employed is prevented, the apparatus is cheapcr and more uniform iu its action than those in which fiuids are used, and= is not aiected'by ordinary changes in temperature.
Should the receiver be injured, no escape of gas from the regulator can take place, exceptin'g where the rod z' passes through the top of the casing; and even should there be a slight lealage here, lthe tight cap j of the ohambe' I prevents the gas from esceping beyond the lattet', while addess to the weghts x is readiy obtained by the removal of the cap.
claim as my invention, and desire to secure by Letters Patent- 1. A. beHoWs-like reeeive', H, applied to a. gasegulator, and connected to the valve of the letter substantially a-s deseribed, so that as the pressure of the gas varies, the reeeiver will expan or contract, zm the opening for the passage of the gas Will be inceased o' diminshed in size. v
2. The chamber I, and its tight (letachable cap j, an'anged on 'the top of the regulator in respect to the v weights x, as and for the purpose set forth.
v In testimony Whereof, I have sgned my name to this specificztion in the presenee of two subscribn'g' Witnesses.
J. B. HOFFMAN.
