: INLET-VALVE FOR CQIVI PR ESSING-ENGINES.

SPECIFICATION forming part of Letters Patent No. 749,323, dated January 12, 1904. Application filed December is, 1902. SerialNo-135,807. (remade) To all whom it may concern: s

provide a simple, economical, and efficient inlet-valve for air compressing and blowing engines.

Further objects of the invention will appear from an examination ofthe drawings and the following description and claims.

The invention consists in the features, combinations, and details ofconstruction herein. after described and claimed. a p In the accompanying drawings, Figure 1 is a vertical sectional view of part of an air compressing and blowing engine as it appears when fitted with an inlet-valve constructed in accordance with these improvements, taken on line 1 of Fig. 2 looking in the direction of the arrowsyFig. 2, a plan view of the same looking at it from above; Fig. 3, a cross-sectional detail taken on line 3 of Fig. 1 looking in the direction of the arrow, and Fig. 4: a

similar view taken on line 4: of Fig. 1 looking in the direction of the arrow.

In illustrating and describing these improvements I have only shown and describedthat which I consider to be new, taken in connection with so much as is old as will properly disclose the inventionto others and enable those,

skilled in the art to practice the same,leaving out of consideration other and well-known parts which, if shown and described herein, would only tend to confusion, prolixity, and ambiguity.

In constructing and carrying out these improvements I take an air compressing or blowing engine having a cylinder at, with a compressing-piston b reciprocatingly mounted therein, all constructed and arranged in the usual manner and the piston being provided with a piston-rod c, which is connected with the prime mover in the well-known manner. One or both ends of this engine-cylinder may be provided, as occasion requires, with a cylinderhead d, through which is arranged a cylindrical passage formed by the fixed wall a. This cylindrical passage, formed by the fixed wall 6, forms a part of and, in fact, is the ;main part ofthe inlet-passage through which the air is admitted to the engine for purposes of compressing. To provide simple and economical inlet-valve mechanism,this cylindrical opening has a flanged cup-shaped piece or wall f axially and removably secured therein, with its outer end flanged at g and also open and its inner end formed of an imperforate wall 72 The flange of this cup-shaped wall is removably secured to the cylinder-head in any wellknown manner, either by bolts or nuts, and its side walls are provided with a series of quadrangular inlet-perforations z, diagonally arranged therein at or near its lower imperforate end. The body of this cup-shaped removable wall is also cylindrical and of a diameter smaller than the fixed wall, so as to provide an annular valve-chamber 7' between it and the adjacent fixed wall. The lower part of this annular valve-chamber is enlarged at 70 to a diameter exce'edingthat of the upper part of such annular valve-chamber, so that the air may have ready ingress, and thus minimize thefrictional resistance as it enters the compressing-chamber. To cover and uncover the inlet-perforations z', a reciprocating sleeveshaped valve Z is provided and mounted in the annular valve-chamber. The upper part of this sleeveshaped valve is preferably provided with an outwardly-extending flange m,

which fits the valve-chamber at its greatest diameter. A packing a is arranged in the fixed wall between it and the reciprocating of the valve-chamber.

the upper end through the wall 1, forming passages for air to and from the upper part To reciprocate such valve and alternately cover and uncover the inlet-perforations during the operation of the engine, a cross-head g is provided and slidingly mounted in the guideways r, secured to a relatively immovable part of the cylinderhead. This cross-head is secured to the reciprocating valveby means of two pins 0 and by means of a link 8 and lever-arm a is also secured to a rock-shaft a, mounted in brackets or standards 'v on the cylinder-head. This rock-shaft is provided with a crank and pin 20, by which it may be secured to some mobile part of the engine-for instance, by means of an eccentric-rod mounted upon an ecentric secured to a rotating shaft on such engine. It will be seen, therefore, that during the ordinary operations of the engine this rock-shaft will be vibrated the desired amount and the valve reciprocated to alternately cover and combination of an engine, a cylinder-head secured thereto having fixed and removable walls forming an annular valve-chamber therebetween, one of which Walls is provided with inlet-perforations, a sleeve-shaped valve in such annular chamber for alternately covering and uncovering the inlet-perforations, and means for actuating said valve during the operations of the engine, substantially as described.

2. In mechanisms of the class described, the combination of an engine provided with a head having a cylindrical opening therein, a cupshaped piece or wall axially and removably secured therein forming the inlet-passage proper and having a plurality of inlet-perforations in the side walls thereof forming an annular valve-chamber between it and the outer immovablewalls of the engine, and a cylindrical sleeve-shaped valve in such annular chamber for alternately covering and uncovering the inlet-perforation in said side walls during the operations of the parts, substantially as described.

3. In mechanisms of the class described, the combination of an engine, a cylinder-head secured thereto and having a cylindrical fixed wall forming an opening therethrough, a flanged cup-shaped piece or wall axially and removably secured therein with its flanged open end portion secured to the outer end of the cylinder-head and provided with a plurality of inlet-perforations in its side walls forming an annular valve-chamber between it and the fixed wall of the cylinder-head, a sleeve-shaped valve in such annular chamber for alternately covering and uncovering the inlet-perforations, a cross-head connected with said valve, and rock-shaft mechanism connected with the cross-head,substantially as described.

4. In mechanisms of the class described, the combination of an engine, a cylinder-head secured thereto having a cylindrical opening therein, a flanged cup-shaped wall or piece removably and axially secured therein with its flanged open end at the outside and provided with a plurality of diagonallyarranged inlet-perforations in its side Wall and forming an annular valve-chamber between it and the adjacent fixed wall, a reciprocating valve in such annular chamber for alternately covering and uncovering such inlet-perforations, guideways secured to a relatively immovable part of the engine, a cross-head in such guideways secured to the valve, and a rock-shaft for operating such cross-head,substantially as described.

5. In mechanisms of the class described, the combination of a main cylinder provided with a pressure-chamber, a cylinder-head secured thereto provided with an annular wall forming an opening communicating with the chamber of such cylinder, an annular wall mounted within such opening and provided with inletopenings therethrough communicating with the inner chamber of the cylinder, and an annular valve movably mounted intermediate such annular walls, substantially as described.

6. In mechanisms of the class described, the combination of a main cylinder'provided with a pressure-chamber, a cylinder-head secured thereto provided with an annular wall forming an opening communicating with the chamber of such cylinder, an annular wall mounted within such opening and provided with inletopenings therethrough communicating with the inner chamber of the cylinder, an annular valve movably mounted intermediate such annular walls, and crank and shaft mechanism connected with such valve for operating it, substantially as described.
