UNITED STATES PATENT OEEICE.
l JOHN F.' ALLEN, OF BROOKLYN, NEW YORK.
AIR-COMPRESSOR.
SPECIFICATION forming' part of Letters Patent No. 237,359, dated February 8l, 1881.
Application filed November 1, 1880. (No model.)
To all whom 'it may concern:
Be it known that I, JOHN F. ALLEN, of Brooklyn, Kings county, and State of New York, have invented new and useful Improvements in Air-Compressors, ot' which the following is a specification.
The nature of my invention consists in the combination, with an air-compressing apparatus, ot' induction and eduction valves, each` the other, and the pistons of both cylinders are attached to one and the same piston-rod O. At the end of the piston-rod O a heavy Weight, D, 'is attached, to which the connecting-rod E connects, the other end ot' Which being connected to the crank F. To simplify the construction this heavy weight D is arranged to act as the guide for the end of the piston-rod.
The steam-cylinder B of the prime motor is constructed,in the usual manner, with suitable valves operated through the eccentric-rods G and H. v
The air-compressing cylinder A is provided with a slide-valve, J, for the induction of the air and suitable ports for the eduction of the same, and having another valve or valves, J arranged on the back face, or it may be arranged on a separate seat, for regulating the eduction of the air. For simplicity and cheapness I prefer to seat this last-mentioned valve or valves on the back of the valve J. These valves receive positive motion through suitable connecting-rods, L L', which connectthe valves directly with the shaftlor it may bea counter-shaft) of the prime motor, the attachment of the rods in this instance to the shaft or counter-shaft of the prime motor being eccentrics.
In all air-compressin g apparatus 'heretofore devised the valves of the compressing-cylinder for the induction and eduction of the air were either of the self-acting kind operated by the pressure of` the air acting underneath them, uncontrolled by any positive motion of the machine itselffor else were at a certain portion of the stroke of thepiston operated so as to cause them either to open or shut, as the case might require; but at all other times they were Wholly uncontrolled by any positive motion, as Was the case ot' the Whollyself-acting valves above described. Consequently, when it was desirable to run the compressing apparatus at a high speed, or any speed above the ordinary, the apparatus lost all, or nearly all, control of the valves, especially the induction -valves through their inertia While at rest and their momentum Whilein motion, and the air-cylinder would therefore compress less air at a high rate than it would at a low rate of speed.
By the combination, with the air-compressing cylinder, of a positive-motion induction and eduction "alve gear the quantity of air that I am enabled to compress is in direct proportion tothe speed ofthe machine.
The eduction-valve J may be placed on a separate seat, as shown in Fig. 3. K is the separate seat, and located in this instance just above the induction-valve J.
Iclaim- In an air-compressing apparatus, theinduction-valve of the compressing-cylinder, connected directly with the prime motor by means ot' a connecting-rod, so that -such valve shall always be moved and controlled in :a positive and uniform manner, in combination with a valve moved and controlled in a positive and uniform manner for regulating the discharge of the compressed'air, each of which valves is operated by mechanism independent of the other, substantially as described.
JOHN F. ALLEN.
