VALVE-REGULATOR FOR SMOKE-CONSUMERS.

SPECIFICATION- forming part Of Letters Patent NO. 629,489, dated July 25, 1899.

Application filed May 23, 1899. $erlal No.- 71'7,965. (N0 model.)

To all whom it may concern.-

Be it known that I, CHARLES E. BRINEY, of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Valve Regulators for Smoke-Consumers, of which improvement, the following is a specification.

My invention relates to means for automatically regulating the admission of steam and heated air above the grate-bars of a furnace during and immediately succeeding the periods in which fuel is supplied. thereto in order thatthe delivery of steam and air to the furnace shall be effected in proper relation to the supply and combustion of the fuel.

The object of my invention is to provide mechanism of such character which shall be readily applicable and effectively. operative in connection with smokeconsuming furnaces of various constructionsheretofore em-- ployed and which may be installed and maintained at comparatively slight cost and without liability to breakage or derangement of its parts in service.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a vertical longitudinal section at the line w w of Fig. 2 through a steam-boiler furnace, illustrating the application of m yinvention in connection therewith; Fig. 2, a view in elevation of one-half of the fire-front thereof; Fig. 3, a transverse section at the line 00 00 of Fig. 1 Figs. 4 and 5, half horizontal sections at the lines y y and z 2, respectively, of Fig. 1-, Fig. 6, a vertical central section, on an enlarged scale, through a valve-regulator embodying my invention; and Fig. 7, a plan or top view of the same. Y

My invention is herein exemplified as applied in connection with a steam-boiler furnace and steam and air feeding accessories of the construction set forth in Letters Patent of the United States No. 609,225, for improvement in smoke-consuming devices, grant-ed and issued to me .under date of August 16, 1898. It is not, however, limited in application to that or any other specific construction of air and steam furnace-feeding devices, and as these do not in and of themselves constitute any part of my present invention they will not be herein described further than is necessary to explain their relation in Opera tion to the mechanism of my present invention.

In the practice of my invention I provide ton 3, and a release or by-pass pipe 9, in which is fitted a regulating cook or valve 10, leads fromone end of the cylinder to the other, on the outside thereof. having a removable cap or cover 12, leads into the upper end of the cylinder 1, and adis= charge-cock 13 controls a passage leading from the lower end of the cylinder to the atmos phere. l v

The cylinderl is provided at or near its lower end with a handle 14, by which it may be raised or lowered as desired, and its circumferential movement about the axial line of the piston-rod is prevented by a recessed lug 15, fixed upon its outer surface and fitting a guide-rod 16-, secured to the supportingbrackets 6 of the piston-rod. An operatingarm 17 is secured to the cylinder and projects therefrom in proper direction to be pivotally connected to an arm 18, secured upon the stem 19 of a steam-supply valve located in a casing 20 and controlling a pipe 21, through which steam is admitted to a plurality of airinjeoting devices 22, which are herein shown as being of the construction'set forth in Letters Patent No. 609,225 aforesaid, by which devices steam and air are'delivered into the furnace 23 above the grate-bars 24: and firedoors 25 thereof.

A supply-passage 11,

In the operation of a valve-regulating mechanism embodying my invention the pistonrod, piston, and cylinder are adjusted in proper operative relation, and the operatingarm 17 is coupled to the stem of the steamsupply valve, the arms 17 and 18 being so set that the supply-valve shall be fully open when the cylinder 1 is at or near the upper limit of ICC its range of traverse and closed to such extent as will admit the volume of steam, which is proper during the intervals between firing, when the cylinder is at-the lower limit of its range of traverse. The cylinder 1 and bypass pipe 9 are then filled with an incompressible liquid, as oil or water, and the regulating-cock l0 opened to a greater or less degree as desired. When either of the firedoors is opened to-fire the furnace, the cylinder 1 is raised by its handle 14 to the upper limit of its range of traverse, the valve 8 in the piston 3 opening automatically and permitting all the liquid in the cylinder to pass to the space above the piston as the cylinder is raised. When the cylinder is released, it graduallydrops by its gravity and that of the contained liquid to its lowest position, coincidently and correspondingly closing the connected supply-valve, the period of the closing movement thereof being dependent upon and proportionate to the degree of closure of the regulating-valve 10, which controls the flow of fluid from the upper to the lower side of the pistonthat is to say, the more fully said valve is closed the longer will be the period during which the supply-valve is moved from its. maximum to its minimum degree of open-.

ing,and vice versa. The adjustment of the regulating-valve is effected by the fireman in accordance With the manner of firing and the character of the fuel employed.

The essential feature of structural novelty which distinguishes my invention from prior constructions designed or adapted to effect the gradual and regulated closure of a steamsupply valve consists in the employment of a cylinder moving relatively to a fixed piston, by which means the Weight of the cylinder and the liquid contained therein is utilized as a motor and the special independent weights and their connections, which have been heretofore provided and which were necessary td that end in prior constructions, are dispensed with. The apparatus is not only thereby correspondingly simplified and reduced in cost, but is also of such character that power sufficient for actuating any desired number of valves may be afforded by correspondingly proportioning the volume of the cylinder.

1 claim as my invention and desire to secure by Letters Patent 1. In a valve-regulator for smoke-consumers, the combination, substantially as set forth, of a steam-supply valve, 21. piston-rod supported vertically adjacent to said supplyvalve, a piston fixed upon said piston-rod, an upwardly-opening valve controlling an opening in the piston, acylinder fitted to traverse on said piston and rod, a by-pass pipe connecting the opposite ends of the cylinder, a valve controlling said by-pass pipe, andan arm connected to the cylinder and to the steam-supply valve.

2. In a valve-regulator for smoke-consumers, the combination, substantially as set forth, of a steam-supply valve, supportingbrackets fixed to a fire-front adjacent to said supply-valve, a piston-rod and a guide-rod, each connected at its opposite ends to said brackets, a piston fixed upon said piston-rod, an upwardly-opening valve controlling an openingin the piston, acylinder fitted to traverse on said piston and rod and having an external lug engaging I he guide-rod, a by-pass pipe connecting the opposite ends of the cylinder, a valve controlling said by-pass pipe,

an arm connected to the cylinder, andan arm connected to the supply-valve and coupled directly to the arm on the cylinder. 7
