GUSTAV B. PETSOHE, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO SOUTHWARK FOUN- DRY AND MACHINE COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.
BLOWING-ENGINE OR COMPRESSOR.
Specification of Letters Patent.
Patented June 30, 1908.
Application filed August 4, 1906. SerialNo. 329,176.
To all whom it may concern:
Be it known that I, GUSTAV B. PETsoHE, a subject of the Emperor of Germany, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Blowing-Engines or Compressors, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.
My invention relates to blowing engines or compressors and has for its object to provide an engine of this kind having the maximum port space for both the admission and de- 'very of the air.
The leading feature of my invention consists in forming the cylinder with a circumferential series or set of ports extending through its side at each end, and with a set of ports extending through each cylinder head, the two sets of ports at each end of the cylinder forming, the one, admission ports, and the other the delivery ports, and in providing valves controlling said ports and operating connections for the valves by which the admission valves are opened and closed and the delivery valves are closed in definite relation to ,the movement of the compressing piston in the compressing cylinder, and in providing means by which the delivery valve at each end of the cylinder is opened when the ratio of the pressure in the corresponding end of the cylinder to the pressure in the receiver into which the pressure discharges rises to a predetermined value. By preference, I employ an oscillating annular valve ring with ports adapted to register with the circumferential ports at each end ofthe cylinder to control the circumferential orts.
Other features of my invention wil be best understood as described in connection with the drawings in which I have illustrated an partial plan view of a modified form of en' gine and Fig. 6 is a section on the line 6-6 of Fig. 5.
A, is the central portion of the cylinder body, B, B, the heads having cylindrical portions which are secured to the cylinder body A so as to form continuations thereof and in which are formed a circumferential series of delivery ports indicated at B. To the end portion of the heads are formed the radial series of admission ports indicated at B. A bearing hub B extends upward from the center of the hub and to one side of the head is formed the supplemental hub indicated at B Through the supplemental hub extends the snifting port B and the hub also serves as a bearing for the shaft indicated at J, and has at its inner end the crank chamber indicated at B said chamber lying outside of the seat for the admission valve which is formed on the inside of the head. As shown, the head casting is formed with an inwardly projecting annular wall B which serves as one wall of the delivery chamber and it is also forrlped with strengthening ribs as indicated at O, C, indicate cast heads fitting on the heads B, as best shown in Fig. 2, and constituting the outer walls of the delivery chambers, said delivery chambers being made up of an annular portion indicated at D, Fig. 4, and merging mto an outlet opening indicated at D, to which openings are connected the delivery pipes or reservoir.
E, is an annular valve ring fitting over the circumferential series of delivery ports and connected through a head E, with an actuating rod P, which, in turn is connected with the piston P of an actuating cylinder 0, the cylinder having a cylindrical extension 0, in which fits an extension P of the piston, said piston extension being made in the form of a hollow cylinder as well shown in Fig. 4 and having fitting in it a plunger Q, actuated through an actuating rod Q, and crank Q by a rock shaft Q which is actuated in turn through the lever arm Q by the rod extension N of an eccentric ring N, fitting on an eccentric N, secured to a positively moving shaft S. The action of the mechanism for actuating the plunger Q, is such as to cause the plunger to move toward the piston at the times when the valve E should be closed, the plunger forcing the piston inward and through its connection with the valve casing, the valve. The 0 ening of the valve is effected by the auxfiiary cylinder and piston O P in any convenient and well known manner, an ordinary plan being that indicated, namely, by connecting the cylinder 0, by a pipe It with the interior of the cylinder A, the valve box R, being situated in the pipe R, as shown and described in my prior patent No. 780,911, dated January 24, 1905.
F, is the compressing piston of the engine which is actuated through piston rod F, in any convenient and usual manner, G, G, indicating stufling boxes at the end of the hubs- B through which the piston rod passes.
II, is the oscillating grid admission valve which works 011 the inner face of the head and over the radial ports B, I, indicating the circular bearing for the hub of the admis sion valve.
J, is a rock shaft supported in the hub 13 and having at its inner end a crank J which moves in the crank chamber B and is connected by a crank pin II with the oscillating admission valve. The rock shaft J and the valve actuated with it as described is actutric N, which is connected with a lever arm,
- as best shown in Fig. 1, the lever arm having a connecting rod K pivotally attached to a crosshead K, moving in a crosshead guide L and actuated through a connecting rod K supported in a bearing L, said lever arm K being actuated by the eccentric strap N through a connecting rod K It will thus be seen that the motions of the admission both of opening and closing and of the delivery valves in closing are performed in fixed. and definite relationship to the movements of the engine which actuates the shaft S while the opening of the delivery valves oc curs at relatively varying times, depending on the pressure in the receivers.
M, is a snifting valve for closing the snifting port B, and this connection it should be noted that the admission valve is formed with a transverse slot H see Fig. 4, which re isters with the snifting port 13 so that the vefive M is always exposed to the full pressure in the compressing cylinder and is free to act at any time if the full pressure exceeds the determined amount for which the valve is set to open.
While I have shown the circumferentially arranged orts as extending around the entire cylint er end and have also shown the radially arranged ports symmetrically disposed about the entire heads, it will be obvious that in either case only such parts as are necessary for the desired. port area need be employed.
Instead of employing an annular valve for the circumferential )orts B", the outer ends of the latter may afl terminate in the same plane as shown in Figs. 5 and 6 and be con trolled by a sliding grid valve B. In this form of my invention a wall 13 corresponding to the Wall E in the construction first described may form three sides of the wall of the delivery chamber, the other side of the chamber wall being formed by a portion of the corresponding cast head C. In this form of my invention, I have shown the cylinder Wall as formed with a water acket.
Having now described my invention, what I claim as new and desire to secure by Letters Patent is,
1. In a blowing engine or compressor, a compressing cylinder having radially arranged ports in its heads with valve seats formed on the inside of said heads in combination with oscillating valves seated 011 said inside seats, shafts extending through the heads and means connected to the inner ends of said shafts for actuating the valves.
