CONNECTICUT.
GAS AND AIR Mix'E'R,
SPECIFICATION forming part of Letters Patent No. 633,789, dated September 26, 1899. Application filed November 19, 1898. Serial No. 696,863. (No model.)
of New Haven and State of Connecticut, have invented certain new and useful Improvements in Gas and Air Mixers, of which the following is a specification, reference being had therein to the accompanying drawings.
Our invention relates to an automatic gas and air mixer, it being designed to automatically regulate the quality of carbureted gas or vapor.
The object of our invention is to provide a simple and compact device which will automatically regulate the mixture of air and a carbureted gas or vapor and which will operate in any temperature.
To this end our invention consists in the gas and air mixer constructed and operating substantially as described, and more particu larly pointed out in the claims.
Referring to the drawings, in which like numerals designate like parts in the several views, Figure 1 is a plan view, partly in section. Fig. 2 is a front elevation, a portion thereof being in section upon line A B of Fig 1. Fig. 3 is a fragmentary end elevation, the casing being in section upon line C D of Fig. 1; and Fig. 4 is a side elevation of the casing and cylinder-beam.
In the drawings the numeral 1 designates the bed-plate 2 and3, the air and carbureted gas-inlet hoods, respectively, which are integral with the said base and provided with. ports which are opposite each other; 4, the air-inlet and 5 the gas-inlet pipes, each being 1 threaded into the said bed-plate concentric to the hoods 2 and 3, respectively, and 6 the gas outlet pipe, also threaded into the said bed- 1 struction, as either tube can be the longer plate.
The mixing-chamber is within the casing 7, which is preferably a hollow casting having I two or more bosses or hubs 8 8 upon the top i side and secured'to the bed-plate 1 in any convenient manner that will prevent air or gas escaping therefrom. .A hole is bored in the casing 7 to provide means whereby access may be had to the interior thereof, and said hole is normally closed by the screw-plug 29.
The numeral 9- designates the hollow cyl- The balauce beam 11 is suspended upon the uprights 17 17, which are integral with the casing 7 and project upward therefrom, the top of the said uprights being'V-shaped, and resting within the same are the V-shaped lugs 18 1S, projecting laterally from the said balance-beam, the whole forming a knifeedge balance.
Within the bosses or hubs 8 S are secured the tubes 19 19 the tube 19 projecting slightly within the interior of the casing 7 "and the tube 19 extending to the top of the base 1, and rigidly fixed to the said tubes are the mercury-cups20 20, each of which is partly filled with mercury or other liquid to form an air-tight seal.
Attached to the cylinder 9 are the inlet and outlet tubes 21 and 22, which overhang from the said cylinder, the downwardly-projecting portion of the said tubes being submerged within the mercury in the cups 20 20. It is desirable that one of the said tubes should project into the cylinder farther than the other to prevent the gas escaping from one tube into the other before it has had an opportunity to circulate within the cylinder, whereby its specific gravity may operate the valve mechanism hereinafter described. In the drawings we have shown the tube 22 as being the long one, but do not confine ourselves to such conwithin our invention.
The valve 28 is fastened to the end of the valve-rod 24 by the screw 25, the said valverod being threaded into the'boss or hub 26 within the pipe 21. In its operative position the said valve is between the hoods 2 and 8 and is concentric with the open ports therein.
The operation of the device is as follows, it being understood that the several parts are illustrated in Fig. 2 as being in their normal positions: Air is admitted into the interiorol. the casing 7 through the pipe 4 and hood 2 and gas through the pipe 5 and hood 3 and unite as they come in contact with each other within the casing 7 and in such condition pass through the tube 19 and pipe 21 into the cylinder 9, escaping therefrom through the pipes 22,19, and 6 to the place of consumption. This process will continue so long as the gas and air are mixed in the propel-quantities, the weights being adjusted to govern the same. If too much gas is admitted into the cylinder, the increased weight of the same causes the cylinder to fall, and the valve 23, whichis upon the lower end of the valve-rod 24, swings toward the face of the hood 3 and closes the gas-inlet port, shutting oft the gas supply, at the same time opening wider the air-inletin the hood 2. There bei ng less gas admitted and the air supply having increased, the mixture within the cylinder becomes lighter and the cylinder and valve assume their normal positions. If too much air is admitted, the cylinder rises and the valve 23 is carried over toward the face of hood 2, sh u tting oft the air-supply until sufficient gas is admitted to bring the cylinder back to its normal position. The slightest variation in the weight of the carbureted gas within the cylinder, caused either by a surplus of air or gas, actuates the valve 23 automatically, shutting off the supply of the surplus ingredient untilaproperbalanceis attained,andthe process of mixing proceeds as before.
If the mixer is located where the temperature is liable to vary greatly from extremes of heat and cold, we find it of advantageto add an additional counterbalance which is affected by the temperature. In Fig. 2 is illusstrated one form of such a device, there being a tube 27 with a bulb at one end thereof, which tube is partially filled with mercury, and a bracket-arm 28 for supporting said tube, in this case the arm 28 being secured to the threaded rod 12; but it may be secured within the cylinder or in any other convenient position upon the beam within our invention. When the temperature is sufticientto heat the gas, which rarefies and becomes lighter, the mercuryin the tube 27 expands and its Weight is carried nearer the balancing-point of the balance-beam. ,This shifts suflicient weight toward the cylinder to make up for the decreased weight of the gas and the normal balance is maintained. In cases of extreme cold the operation of the temperaturebalance is the reverse.
There are minor changes and alterations that can be made within our invention, and we would therefore have it understood that we do not limit ourselves to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of our invention.
Having fully described our invention, What we claim as new, and desire to secure by Letters Patent, is
gas, of means for proportioning the gas and air supply into said mixing-chamber, the said means being operated by the movement of the said receptacle, substantially as described.
3. In a device of the character described, in combination with a mixing-chamber and a balanced receptacle, a valve operated by the movement of said receptacle and adapted to open and close the air and gas ports through which air and gas are admitted into said mixing-chamber, and mechanism for regulating the movement of said receptacle whereby the normal position of the said valve is varied, substantially as described.
4. In a device of the character described, the combination with a hollow receptacle havin g inlet and outlet connections, of a balancebeam rigidly fixed atone end to said receptacle and having weight mechanism upon the opposite end, a mixing-chamber, and a valve operated by said receptacle for proportioning the quantity of gas and air admitted to said mixing-chamber, substantially as described.
5. In a device of the character described, the combination of a hollow frame forming a mixing-chamber,inlet-ports for the admission of gas and air thereto, a valve adapted to operate between said inlet-ports, a hollow receptacle having a flexible connection with the said frame, and means for joining the said valve and the said receptacle whereby the said valve is operated, substantially as described.
6. In a device of the character described, the combination with a mixing-chamber having oppositely-disposed inlet-ports and'a single outlet-port,a balance-beam having adj ust able weights upon one end, a hollow receptacle secured to said balance-beam and provided with inlet and exhaust tubes and having a flexible connection with the said chamber, and a valve within the said chamber rigidly secured to the said inlet-tube and oper ating between the said inlet-ports, substantially as described.
