FRED E. YOUNGS, OF ALLEGHENY, PENNSYLVANIA.

AIR OR GAS METER.

SPECIFICATION forming part of Letters Patent No., 485,075, dated October 25, 1892. Application filed December 19 1891. Serial No. 415,672. (No model.)

To all whom t may concern.-

Be it known that I, FRED E. YOUNGS, ot' Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvementsin Valve Mechanisms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to improvements in valve mechanisms which are especially intended and adapted to be used in connection with meters; and it consists in certain novel features ot construction and arrangement of parts, which will be fully described hereinafter.

The object of my invention is to provide a valve mechanism for controlling direct-actin g valves so constructed and arranged that under no conditions can t-he valves leading to or from both sides of the pistons be opened at the same time.

In the drawings, Figure l is a vertical section of a meter embodying my invention taken on the dotted line .e e, Fig. 3, and on the dotted line o. b of Fig. 2, above the line y y, and the boxes into which the piston-rods extend being sectioned on the dotted line c (l of Fig. 2. Figr2 is a horizontal section taken on the dotted line ocxof Fig. l. Fig. 3 is a similar View taken on the dotted line yy of Fig. l. Fig. 4 is a horizontal section taken on dotted line @c of Fig. l with the valve mechanism revolved. Fig. 5 is a vertical section taken on dotted line 5 5 of Fig. 4L. Fig. 6 is a vertical section taken on dotted line 6 6 of Fig. 4. Fig. 7 is a vertical section taken on dotted line 7 7 of Fig. 4. Fig 8 is a vertical section taken on dotted line 8 S of Fig. ft.

A indicates a cylindrical chamber, which is divided by a horizontal partition B into an upper valve-chamber and a lower cylinderchamber, which latter is divided into two chambers D E by means of a vertical partition F. Placed within these cylinder-chambers are the vibrating pans or pistons I J, which are made of a crescent shape, as shown in Fig. 3, to allow room for ports between. The valve-chamber is divided into two chambers L M by the boxes K and the vertical partition O, which extends from the top of the case to the horizontal partition B. Passing through the pans are piston-rods N, which are guided by suitable bearings at their upper and lowerends, as shown. Connected at their lower ends to a cross-head placed on the piston-rods are the links P, which have their upper ends connected to the 'inner ends of arms Q Q', which extend inward from the rock-shafts R R. These rock-shafts are journaled upon suitable supports, which extend upward from the partition B, as shown.

The chambers D and E are lled with liqqid, preferably oil, to the level indicated by dotted line f g in Fig. l, so that gas passing into the said chambers D E forces the pans I J down, as will be understood. Secured to the under side of the bottom of the chambers D E is the passage S, serving to connect the lower ends of the ports b g with the opening V directly under the pan I. Also placed under these chambers D F. is a passage T, which serves to connect the bottoms of the parts ce with the under side ofthe pan .l through the opening U. The parts a, d, f, and h are connected directly into the upper ends of the cylinder D E.

The rock-shafts R R are operated by the pans IJ, as will be seen, and these rock-shafts operate the valves. Connected with each of the valves are two arms c', which have their outer ends pivoted upon the shaft j, which are supported a suitable distance above the partition B by means of brackets, as shown.

Secured to the rods or shafts j between the ends ot the arms vL' are collars 7.3, which hold the arms against lateral movement upon the rods and the valves in place upon or over their seats, as will be seen. The inner ends of these rods are connected with the valves by means ot' any suitable universal joint, so that'the valves will seat themselves squarely and evenly upon the whole surface of their seats, thus making at all times a gas-tight joint. This joint consists of a circular cap (Z2, having a suitable filling, upon which a disk a2 rests, and upon this filling the disk rocks in any direction, being loosely held in place by lips b2, extending inward over the said disk. v

Connected at their lower ends to the valves ICO a essere manner the valves 3 and 4 are connected -to the upwardly-extending arm r on the rockshaft R, and on the other side of the partiv io tion the valves 5 and 6 are connected to downwardly-extending arm a: on the rockshaft R, and the valves 7 and 8 are con-` nected to an upwardly-extending arm 'y on rock-shaft R. and V and extending upward from the bot- Ytom of the chambers 'D E are'the walls G and 5o tion the port A will be described as the in- H, which are vof a shape corresponding to the shape of the pans and titclosely within them. This arrangement reduces toa large .extent vthe amount of oilnecessary to illithe chambers to the proper level, as shown bythe dotted line f g. lOn the rock-shafts R and R arms tare connected by the links u with a @rank on the sha-ft w, Vwhich operates lany suitable registering lmechanism vand also Vserves t0 keep the Pacs in the sameleiative position with reference to their stroke, So that when one pan is at the end of its stroke and its connection to the .crank on it-s dead-center the other pan will be ,about in the middle lof its stroke, thus permitting a uniform urotation of the Icrank.

Owing to the fact. vthat one valve of each pair forms the fulcrum upon which the other is raised, it is absolutely necessary for one valve of each pair to be properly seated before the otheris opened, which prevents abso- Yluteiy the opening ,of Vbothvalves Aat the same time, or Ithe opening .of one valve in each pair in advance `of ,the closing of the other valve, even -to ,the slightest degree. This is a serieus and .common defect rof ordinary meters, which is positively avoided in my meter in the manner just set forth In operation the gas, air, or steam may be `fed into either the chamber L or the `chamber M, as desired, the only eifect being to reverse the motion of the meter.

'For the purpose of illustrating the operalet and the port B as the outlet port, As shown iu Fig. 1, the pan I is at the upper limit of its stroke, the pan J moving down, and gas passing from the chamber M through the open valve 4 to the chamber E above the pan and forcing it down, while gas is passing from the under side of the pan J through the passage T and port e, controlled by valve 5, to chamber L. The continued downward ,movement of Vthe panY J opens the valve l, controlling port a, communicating with the chamber D, and on the other side of the .partition C opens the valve 8, controlling the port 7i, which communicates with the under side of the pan I through the passage S at the instant the pan I has reached the upward limit of its stroke. When the pan J reaches the Surrounding the'openings UA downward limit 'of its st rQke, the valve 4, con trolling the port d, which communicates with the upper side of the pan J, is closed by the downward movement of the pan I, and the valve 3, controlling the port @,which communicates with the under side of the pan J through the passage T, is opened, thus admit-v ting gas below the pan J,and at the same time the valve 5 is closed and the valve 6 is opened, allowing the gas from the upper side of the pan J to escape through the port f into the chamber L and through the outlet-port B. The valves l, 2, 7, and 8, which control ports for admitting and exhausting gasto operate the pan I, are operated and controlled by rock-shaft R", which iswoper-YY ated by .the pan J, and the valves 3, 4, 5, and 6, which coact with the pan J are operated and controlled by the rock-shaft R, which is ,connected with the pan I. From athis i-.t will be seen that ithe valves which ooact with .one pan are .operated and controlled by themovementof the other pan. It willalso be understood from this description that gas is fed .to and exhausted from `opposite sides .of the pans in a manner similar toadmitting and exhaust.- ing steam to and from opposite sides of the piston of a steam-engine. v

While I here showand describe a pan which is operated upon by the gas, I do not limit myself to the use thereof, for itwill be understood that a diaphragm-piston or other similar device may be substituted therefor without affecting the construction oi'foperation of my valve mechanism in any manner whatso" ever. Neither do I limit myself'to the use of this valve mechanism in a meter, for it will Yloe read-ily conceived Vthat it may be used inY connecticn with marine or other engines, pumps, and in many other similar machines which feed and exhaust steam, air, gas, water, or other `4fluid to opposite sides of the piston, pan, diaphragm, or vother similar me.- chanieal element..

l do not i-n thisapplication make any claim yto a valve mechanism comprising two or more valves connected and moving in pairs and each pair fulcrumed upon another pair, for this is made the subject-matter of my pend.- ing applica-tion, Serial No. 415,673.
