SPECIFICATION forming part of Letters Patent No. 340,279, dated April 20, 1886 (No model.)

To all whom it may concern;

Be it known that I, LUOIUS BRIGGS, of Glasgo, in the county of New London and State of Connecticut, have invented certain new and useful Improvements in Condensers for Steam- Engines, ofwhich thefollowingis afull, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification.

My invention relates to the class of condensing steam-engines which condense the exhauststeam by injecting the same into a chamber, where it is brought in contact with a jet of water. In these engines it becomes necessary to provide means whereby the water of condensation from the condensed steam and the water from the cold-water injector for condensing the steam are readily and effectively removed from the condensing-chamber.

The object of my invention is to provide what I may term individual condensers" for each exhaust-valve of the steam-cylinder, and which are worked automatically, each in conjunction with its connected exhaust-valve, so that the complete system of my condensers is operated and controlled by the steam valve cut-off motion.

To the above purposes my invention is in the nature of the combinations and sub-combinations of theessential parts, as hereinafter fully described and claimed.

The accompanying drawing illustrates an elevation of an ordinary steam-cylinder with a portion of the steam-pipe and engine-frame, and with my improved condenser shown in section as attached below the cylinder and extending below the floor 40.

Referring to the said drawing, 1 designates the steam-supplypipe leading into the steamcylinder 2, which is clothed with a wooden jacket, and having the portion 3 of the engineframe extending from one side. At the two upper corners of the figure are located the steam-valves 4 and 5, respectively, which are in turn connected to the governor of the engine by the bars 6and 7. (Shown in portions.)

The stems of the steam-valves 4 and 5 are each provided with a crank-arm, 8, keyed to them. At the two lower corners of the figure are located the exhaust-valves 9 and 10, respectively. The stem of the exhaust-valve 9 is provided with an approximately Y- shaped crank,-11,

and the stem of valve 19 is provided with an Lshaped crank, 12. Upon the shaft 13, fixed upon the side of cylinder 2, is looselyjournaled the wristplate ll, which is something 6f a balloon shape, and has its small end connected suitably with the rocker-shalt 15, which is in turn connected with the main eccentric. (Not shown.) The wrist-plate 14 hasloosely mounted thereon four wrists, 16, from which run the rods 17, which are jointed to the valve-stem cranks 8 8, ll, and 12, respectively.

It is evident that these above-described connections operate in the usual manner of the well-known form of Corliss engine to control I the induction and eduction of the steam driving the piston.

The following description relates to the construction of my improved condenser. The exhaust-pipes 18 lead from the exhaust- ,ports of the valves 9 and 10, respectively, into the chambers 19, which are small cylindrical condensingchambers with the injectors 29 projecting through their outer ends and lying in their long axes. These injectors 20 are suitably perforated upon their uppcrsurfaces, and have their outer ends connected with the cold-water-supply pipes 21, and are provided with the ordinary rotary valves, 22, have keyed to their stems the cranks 23, the other ends of which are fastened one to the Y- crank 11 and the other to the L-crank 12 by means of the rods 21. From the lower sides of the chambers 19 lead the pipes 25, which are shown as screwed into the mouths of the valve-casings 26, which are suitably shaped like small cylinders, and have therein the rotary valves 27 ,which open and close the communication between the condensing-chamber l9 and the main 33, into which the valve-casings 26 open from their lower sides. This which 8:

main 33 is an ordinary pipe-main which leads to the hot-water tank. (Not shown.) The rotary valves 27 are rigidly fastened to the cranks 28, which are connected by movable joints to the rods 29, both of which are loosely jointed to the disk 30. The disk 30 is mounted and turns on the fixed journal31, directly below the journal 13 of the wrist-plate 14. The disk 30 is connected upon one side loosely to the rod 32, which is likewise connected at its other end to the wrist-plate 14. All these described connectingrods which connect the wrist-plate with the various valves, and the exhaust with the injector-valves 22, and the condenser-valves 27 with the disk 31, and the disk 31 with the wrist-plate 14, operate in a mutually reciprocating and rocking manner.

In the position shown by the figure the steam-valve 4 is opened and its corresponding exhaust-valve,9,is closed,its injector-valve 22 is closed,and its condenser-valve 27 opened.

Considering the right-hand condenser, the

steam-valve 5 is closed, its corresponding exhaust-valvc, 10, is opened, its injector-valve 22 is opened, and its condcnser-valve 27 is closed. These condensers alternately operate one at a time, and a description of one will suflice for both. Referring to the right-hand condenser, the piston (not shown) in cylinder 2 having reached the limit of left-hand traverse, the steam-valve is closed, the exhaust 2o 10 is opened, likewise the injector-valve 22 (to inject the water-jet through the perform t-ious into the chamber 19) and the condenser valve 27 is closed. The exhanststeam flowing through the exhaust-valve 10 is carried onto the injector 20, which sprays the cold water whereby the exhaust-steam is condensed, and the resulting water of condensation and water from the injector together gravitate from chamber 19 to pipe 25, where it remains confined by valve 27. XVhen the rocker-shaft 15 is now drawn to the extreme left, the wrist plate 14 turns on its shaft and comn'iunicates motion to all its connected parts. Then the piston is at itslimit of right-hand traverse and 35 the condition of all the valves is reversed from the order above described, and the wateriiow-s" out from the righthand condenser. being released by eondenser-valve 27, and into the main 33, which subsequently conveys it to the.

0 hot-water tank.

It is obvious that my condensers are autostance, if necessary for the more perfect operation of the condenser in discharging the waste water, there may be substituted for the oneway valves 22 threeway valves which open into the little air-vents 50. (Shown in broken lines.) This will operate to admit sufiicient air into the condensing-chamber at the proper moment to drive the water out into the main 33.

Having thus described my invention, I claim as newai'iddesire to secure by Letters Patent- 6 5 '1 In a condenser, the injector eoacting and connected with its corresponding exhaustvalve. substantially as set forth.
