a w/wrn it may concern Be it known thatI, MARVIN A. NEELAND, of Youngstown, Mahonin r county, Ohio, have invented a new and usefu Valve for Blowing- Engines, &c.', of which the following is a fit l, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is atop plan view showing one form of my improved valve. Fig. 2 is a crosssectional view on the line II II of Fig. 1, showing thevalve in closed position. F 3 is a view similar to Fig' 2, showing the valve in open position. Fig. 4 is a to plan view showing another form of the va ve. Fig. 5 is a longitudinal section or" the form of Fig. 4. Fi 6 is a view similar to Fig. 5, showing the va ve in open position; and Figs. 7 and 8 are partial plan views of the head of a blowingen in'e, showing difierent arrangements of the va ves of Fig. 4.

My invention relates to that type of valves valves aretormcd by cutting strips from the valve-body. v

. The object of the invention is to give a substantially parallel lift to the valve] and uni-,

'iorrn bending of the valve-stripand to r0- vide guards for the valve which will a low passage of the air theretllrough, as well as around the valve,

In the drawings,referring to the form of Figs. 1, 2, and 3, 2 Srepresent valve-ports arranged intwo annular series. 4 is the valve, which consists of a thin sheet-Inetaldisk with curved spring portions 5 cut therel'rom, these curved springs lying intermediate between the two series of ports. As shown in Fig. 1 the side edges of this cut strip are not'parallel, but are tapered from both ends toward its central portion. The end portion of each strip is secured by a screw-bolt 6 or other suitabledevice to the head of the compressor or blowingengine cylinder. In the rear of the valve is a back-stop 7, consisting of a plate of circular form, secured by a screw-bolt 8, extending through its central portion and through the valve into the cylinder-head. Thisback-stop is provided with curved ports 9', which are ar ranged in' two annular series out of registry with the ports in the head.

In the normal position of the valve the spring-strips hold the valve in. closed position, F ig. 2, and when pressure is brought upon the lower side or suction exerted on the of Fig. 3. In this opening movement, owing to the tapered form of the sprin the bending action of the spring-strips will be uniform and regular, thus preventing excessive strain and injury. to the springs. When the pres sure or suction is released, the springs again draw the valve to itsseat.

In the form of Figs. 4, 5, and 6 the valve is in the form of a rectangular strip 10, having at one end a spring-strip 11, secured at 12 to the valve-seat or cylinder-head. The springstrips 13 are substantially the same as those of the first form, except that the extend straight instead of on a curve. T e r ends are secured to the cylinder-head, as before,

ports 14, the closed position being shown in Fig. 5 and the open position in Fig. 6. In Fig. 7 I show one arrangement of these valves of Fig. 4 on a blowing-en ine head in which they extend parallel wit each other. In Fig. 8 I show another form in which the ward the circumference of the head.

The advantages of my invention result from the tapering form of the integral sprin also from the back stop or guard, which a lows the passage of air past each edge of the valve from the closing of the valve by the The valve is simple an cheap and not'liable to get out of order.- l

Variations may be made in the form and arrangement of the valve, the spring-strips, &c., without departing from my invention.

1.. In a blowingen inc or compressor, a thin sheetmetal va ve having a ta ered spring described. I

2. In a blowing engine or, compressor, a thin sheet-metal valve having spring-strips out of registry with the air-ports, said strips 3. In a blowing-engine or compressor, a thin sheet-metal plate with integral springs cut therefrom, the endof each s ring being secured to the cylinder-head, an the spring being tapered from each end toward its central portion; substantially as described.

' i. A blowing-engine or compressor having a valve comprising a thin sheet-metal late having strip springs out therefrom an free upper side the valve will lift into the position valves extend radially from the center to integral therewith; substantial y as being tapered; substantially as described.

at ne end, and a back-stop having ports in and they are placed between the series of springs and the substantially uniform lift, due -to the shape and arran ement of the springs;

5. In a, blowing-engine 'or compressor, an. airwelve consisting of per-ellelstrips of thin (sheet metal united at intervals, with tapered gsprings between and integral with said strips, and a back-stop arranged to limit the lift of ithe valve and permit passage of air past each edge 5 substantially as described.

6. In a blowingengine or compressor, a thin sheet-metal Valve having integral strips the s rings; Substantially as eut therefrem "with their free ends secured to the piete eenteining valveports, and ranged. to normeaiy drew the valve to its seat substantieliy as described.

In testin'iony whereof I have hereunto set my hand.
