VALVE FOR BLOWING-ENGINES.
Specification of Letters Patent,
Patented Nov. 13, 1906.
Application filed December 26,1902. Serial No. 136.653.
To all whom, it may concern:
Be it known that I, JOHANN FREDERICK MAX PATITZ, a citizen of the United States, residing at Milwaukee, ill the county of Milwaukee and State of Visconsin, have invented certain new and useful Improvements in Valves for Blowing-Engines, of which the following is a specification.
This invention relates to that class of valves which is used as inlet-valves for air compressing or blowing engines, and particularly to the arrangement and construction thereof, as will more fully hereinafter appear.
The principal object of the invention is to provide a simple, economical, and efficient balanced inlet-valve for air-compressing and blowing engines.
Further objects of the invention will appear from an examination of the drawings and the following description and claim.
This invention consists principally in the combination of an engine having an inletopening the side walls of which are provided with a plurality of inletpassages, a cylindrical valve reoiprocatingly mounted in such opening to cover and uncover the inlet-pas sages, and a passage or passages for conveying fluid to the rear of the piston-valve to balance the same, substantially as described.
The invention consists, further, in the combination of an engine having a hollow cylinder-head, an inlet-opening formed of a removable cylindrical shell which also forms a valve-guide and having a plurality of inlet passages in the side walls thereof opening into the hollow space of the cylinder-head, means for holding this removable wall in engagement with the cylinder-head, and a cylindrical valve reciprocatingly mounted in the interior bore of the valve-guide to cover and uncover the inlet-passages.
The invention consists, further and finally, in the features, combinations, and details of construction hereinafter described and claimed.
In the accompanying drawings, Figure 1 is a sectional elevation of one end of a blowingengine cylinder as it appears when fitted with an inlet-valve constructed in accordance with these improvements; Fig. 2, a plan view of the same, and Fig. 3 a plan sectional detail taken on line 3 of Fig. 1 looking in the direction of the arrow.
In illustrating and describing these improvements I have only illustrated and described that which I consider to be new, taken in connection with so much that is old as will properly disclose the invention to others and enable those skilled in the art to practice the same, leaving out of consideration other and wellknown mechanisms which if described herein would only tend to confusion, proliXity, and ambiguity.
In constructing an engine in accordance with these improvements I make a cylinder a of the desired size, shape, and strength and provide one or both ends thereof with a hollow cylinder-head b, detachably securedthereto in any usual manner, so as to close such end in the desired manner. To provide for the inlet of air at the desired time or times to such cylinder, so that the reciprocating piston c therein may compress it as desired the cylinder-head is provided with a cylindrical inlet-opening formed by a cylindrical tube or shell d, open at its inner end into such cylinder and closed at its outer end by means of a cap or cover 6, which is secured to the mechanisms outside the flanged end f of such cylinder-shell. This securing means may be bolts, studs, or other similar mechanisms, all of which are well known and need no further or detailed description herein. This cylindrical shell, as above stated, forms what may be properly termed the cylindrical inletopening above described, in that the opening into the compressing-cylinder is free and unobstructed, and it acts, further, as a guide for the valve, as will hereinafter appear. It is further provided with a plurality of inletpassages g in the side wall or walls thereof, which connect the cylindrical opening of the compressing-cylinder with the space h in the cylinder-head, which head is also provided with an opening into the outer air. (Not shown.)
-To cover and uncover the inlet-passages by and during the movements of the engine, a cylindrical piston-valve i is provided, mounted in the central bore of the cylindrical shell and provided with the usual packingrings j, which prevent leakage of the air through the same and also take up the wear of the parts. This cylindrical piston-valve is provided with a plurality of longitudinal balancing-passages is, extending fromthe front to the rear end, so that the fluid may pass therethrough and serve to balance both sides of the piston-valve. The piston-valve is further provided with a valve-stem Z, axi ally secured thereto and passing through a stufling-box m in the outer cap or cover. To operate this piston-rod, across-head *n is pro vided having screw-threaded engagement therewith, which engagement is locked or regulated by means of a jam-nut 1). To guide the cross-head in its movements, the cap or cover is provided with two outwardlyextending guiding-arms g, integrally formed therewith, between and in which the crosshead is slidingly mounted, as shown particularly in Fig. 1. A rock-shaft r is provided, vibratingly mounted in arms or brackets t, removablysecured to the outside of the cylinder-head, and such rock-shaft is further provided with a lever arm or arms a, which engage with a sliding block 2; in the crosshead by means of a pin or rod w, so that during the vibrations of the rock-shaft the crosshead, and through it the cylindrical. pistonvalve, is reciprocated to cover and uncover the inlet-passages at the proper time or times I claim- In an engine of the class described, the combination of a cylinder provided with a reciprocating piston, a hollow cylinder-head detachably secured thereto having circular openings in the upper and lower walls thereof, a cylindrical valve-shell extending through the upper opening and secured to the inner face of the lower opening and having upper iinperforate and lower perforate portions, the latter communicating with the air-spaces of the cylinder-head, a piston-valve arranged in said cylinder-shell and provided with a plurality of large-sized continuous openings extending entirely therethrough and parallel with the axis thereof for free balancing, an inwardly-extending lip upon the lower opening into the cylinder-head to prevent the valve-piston from falling into the engine-cylinder, a cap or cover 6 removably secured to the valve-guide and closing the outer end thereof, a valve-stem axially secured to said piston-valve and extending out through the cap of the valve-guide, cross-head guides on said valve-guide cap extending outwardly therefrom, a cross-head mounted in said cross-head guides and having adjustable screw-threaded engagement with the valvestem, and rock-shaft mechanism for operating said cross-head and thereby the parts secured thereto, substantially as described.
