, To all whom it may'concern nIsK=vALvE ivr'norraNrsm Be i known that I, FRANK -E. TE N-EroK,

a citizen of the United f States, residing at Auburn, in'the,county of, Cayuga and State of New, York, have invented certain new and useful Improvements in Disk-Valve Mechanism; and I do hereby declare the following to be a full, clear, and exact de- "scription of the invention,-such as will enable others skilled .in the art to whichit appertains to make and use the same.

My invention consists in the novel features hereinafter set forth reference being had to the accompanying drawing which Fig. 3 is an elevation'of the inner face of.

illustrates two embodiments of the invention, selectedby-me for purposes of illus tration, and the said invention is fully dlsclosed in the following description and claims.

Referring to'the said drawings, Figure 1 represents a vertical sectional view of one embodiment of my invention designed more particularly for use as a distrlbuter.

Fig. 2 is a front elevation of the apparatus shown in Fig. 1, with cover and valve removed.

the disk valve proper. Fig. 4 is a top plan .view, partly in section, of a different form or embodiment ofmy. invention, adapted more particularly for'use as a controlling valve to be operated by hand or otherwlse. Fig. 5 is a vertical sectional view of the I same. ,Fig. 6 isfa front elevation of the device shown in Figs. land 5 with the cover and valve removed. ."Fig. 7' is an elevatlo of the inner face ofthe disk valve.

- .My'invention relates todisk. valve mechanism adapted especially for use .in connection with compressed. fluidstarting mechanism for internal combustion engines, such forexample, as. is ,l illustrated in 1 my former applications ,for- Letters Patent ,of. the United States, SerialNos. 844,611 filedJune 12, 191 1, and 22,551, filed: :April '20, p 1915, although this valve mechanism is not limited to use in a system-of this kind,- v In the drawing accompany ng and form-- ing a part of this applicatidn, I have shown form illustrated in Figs. 1-, 2, and 3 being adapted for use particularly, although not necessarily, as a distributer for distributing compressed fluid to the several cylinders of an internal combustion engine for starting Specification of Letters mat-j 1- Application filed May 12, 1915; Serial K012 7515.

the! same,;in "-{a predetermined manner, in

whlch case the valve proper will ord1- narily be rotatable, as shown, and operated 'by any suitable connectionsin timed'relavalve proper oscillates instead of rotating as in the other form of the invention.

Referring to the form of my invention illustrated in Figs. 1, 2, 3, the valve casing or body '22 is provided with a cylindrical wall interiorly threaded near its outer edge, and with a plane circular inner or bottom face 23, which is preferably ground so as toi be perfectly true, and is provided with 'one or more delivery ports or outlet ports 24. In this instance there are four ports 24 communicating by passages in the valve body with pipe connections 2*, 3 4 and 5,

which, when the device is used as a distributer, lead" to the several cylinders of the internal combustion engine. 21 represents the.

valve actuating. shaft which has a portion extending through the valve body'concentrically with-the cylindrical portion 22 and preferably projecting slightly beyond the inner ground face 23 of the valve body. The inner end of the shaft 21- is provided -with means to interlock with the valve proper in order that the latter may rotate witlithe shaft, and in this instance I have 1 shown the s'haftprovided with a pair of circular holes or recesses 27 in its inner face, located on opposite sides of the axis of the shaft. 'The valve body is also provided --W1tl1 an annular recess 33 surrounding the inner end'of the shaft. The disk or valve proper is indicated at 25, and the inner face 26 thereof, which is shown in Fig. 3, is

- ground to fit the ground face 23 of the valve casing and is provided with a central cylindrical recess 29 to .fit over the-end of the shaft 21, and the valve is provided with interlocking devicesv for engaging the shaft, comprising in this instance, a pair of pins "28 extending-intotherecess 29 and adapted to engage the recess 27 in the end of the shaft. The general shape of the valve proper is that of a circular plate or disk, but the-exterior face of the valve is providedwith a thickened central portion forminga hub or boss preferably circular in cross section. The plate portion of the valve outside-of the hub is provided with a port or aperture extending entirely through the disk or valve, and the inner face 26 is also provided with a recess 31 locatedat about the same distance from the center or axis of the valve as the aperture 30. and connected by a recess or passage 32 which extends toward the center of the face 26, in this instance, to the recess 29,

' but it is suflicie'nt if it extends far enough end of the spring will engage the outer plate portion of the valve, while the outer end of the spring will engage the inner face ofthe'cap or cover, thus serving to hold the ground face 26, of" the valve in frictional and fluid tight engagement with the ground face 23 of the valve body, while permitting the valve to be rotated by means of the shaft 21. The valve being removable from the shaft and connected thereto by interlocking means, it can be readily removed from the casing when desired for regrinding or other purposes, and it is not essential to secure the perfect perpendicularity of the shaft 21 with the plane of the ground faces 23 and 26 .as the interlocking connections between the valve and shaft'will accommodate variations therefrom and still permit the valve to be maintained in proper relation with. the ground face of the casing.

The valve body is also provided with a relief passage 34 extending from the annular V recess 33 to the exterior ofthe valve casing andcommunicating with the atmosphere, as

I shown in Figs. land 2, for the purpose of permitting an outward discharge or relief from the ports of the valve body through the recess 31 and passage 32 in the face of the disk valve;

When this device is used as a distributer,

it will be understood that the shaft 21 will be operated in timed relation with the crank shaft of the engine. The compressed fluid will be admitted throughpipe'38 to the interior of the va-lve'casing and w-ill be distributed through the aperture 30 in the.

valve-to the successive ports 24 as the valve rotates, and thence to the appropriate cylinder' of the explosive engine with which the apparatus is used. I prefer to locate the centers of the aperture 30 and the recess 31 at the same distance apart as two o'f'the disk valve are provided with interlocln'ng ports 24 and to locate the recess 31 in advance of the aperture 30 as shown, so that, as the valve is rotated, when the aperture 30 is over one. port 24, the recess 31 will be over the preceding port, which will be in communication with a cylinder which is next in firing order, and which is compressing, thus permitting the exhaust 'or relief of pressure in that cylinder through the recess 31, passage 32, annular recess .33, and relief aperture 34, as will be readily understood. I

In the form of my invention shown in' Figs. 4 to 7 inclusive, the body of the valvecasing is provided with'a cylindrical wall having an internally threaded portion near its outer edge and having an inner ground circular face 61 to engage-the inner ground face of the disk valve 65, which is constructed with an exterior central boss The inner face of the valve body is provided in this instance with two ports 62 and 63 which are connected respectively by passages with thepipes 18 and 38, The valve 65 is provided with two apertures 62 and 63 through the disk or plate portion there of, and its inner face is also provided with a central recess 65? and with recessed portions 65 and 65 communicating in this instance with the central recess 65 and forming the relief recess or recesses.

7 0 represents the. actuating shaft for the a valve, which is provided with anenlarged portion within the valve body having formed therein an-annular recess and provided with a longitudinal groove or recess 70 communicating therewith and ex tending through to the inner end of the shaft. The inner end of the shaft and the means, in this instance pin 71, projecting from the valve and extending into recesse in the inner face of the shaft.

In using this device as a-controlling valve, I preferto oscillate it instead Ofrotate it,- and to provide means for limiting the movement of the valve in both directions. In this instance I have shown the shaft 70 provided with a sleeve adjacent to the rear por-' tion of the valve body, said sleeve being rigidly secured to the shaft 70 by'set, screws 110 and the'sleeve being provided with a stop lug or pin 111 projecting from the inner end of the sleeve, "and adapted to engage stop shoulders 112 formed on the adja':

cent portions of the valvebasing. 4

In some instances it is desirable to make the shaft 70 in two sections, to wit, a. short section extending into the valve casing and a longer section united thereto and extending to some point where an actuating arm or other hand operated or other device is to be applied for oscillatingthe shaft, and p as the, length of the exterior portion of the shaft may vary in different situations in, 1 0

6 which the valve is used, it is convenient to make the shaft in two parts as here shown, in which case the sleeve 110 may be applied to the inner section of the shaft and secured thereto by one of the set screws 110 and the exterior portion of the shaft may be inserted in the other end of the sleeve and held in relation to the sleeve and the other section of the shaft by the other set screw 110 so that the sleeve will also act as a coupler, but this is not essential to the invention. In some instances it is desirable to attach a pressure gage to the controlling valve, and for this purpose I conveniently provide the valve casing with a screw threaded aperture at its upper end to receive a pipe 109 as shown, which may lead to the pressure gage, the said threaded aperture being connected by a passage 64 with the interior of the Valve. casing. If the pressure gage is not desired, the aperture and passage 64 can be closed by a plug. The valve body is also provided with a relief passage 60 which communicates with the annular-recess 70 and longitudinal recess 7 0 and hence with the relief recesses 65 and 65 in the face of the valve 65. The valve body is also provided with a closure or cover 67 which screws into the threaded portion of the annular wall 60 and is pro vided with a centrally threaded opening to receive the inlet pipe 80, which may be connected with a source of compressed fluid. A. coil spring 66 is also inclosed between the cap or cover and the rear face of the valve and surrounds the boss 65 to hold the ground face of the valve and casing in contact. The

operation of this valve mechanism is analogous to that of the mechanism previously described, but it differs therefrom on account of the fact that the valve is intended to oscillate instead of rotate. In the neutral position of the valve 65, that is to say, with the pin 111 midway between the two shoulders 112, the relief recess 65 and 65 will be in engagement with the ports 62 and 63,- thus relieving the pipes 18 and 38 and their connections to the atmosphere through the recesses 70 and 7 0 and passage 60*, and as the openings 62 and 63 -are over .closed and solid portions of the face 61 of the valve casing, pressure fluid from the pipe 80 cannot pass through the valve mechanism. When the valve is oscillated in one direction 112 the aperture 63 will be brought into registration with the port 63 and will therefore admit pressure fluid to th pipe 38, while if the valve is oscillated 1n the opposite direction until stopped, the aperture 62 will be brought into registration with the port 62 and establish connection between the pipe 80 and pipe 18. As soon as the valve is restored to neutral position, either (or 'both) of said passages 18 and 38 and until arrested by the stop and shoulder their connections will be relieved of pressure through the exhaust ports to the at mosphere, as before described. This form of valve I find'advantageous and eificient foruse as a hand actuated controlling valve for compressed fluid starting mechanism for internal combustion engines, in which case the pipe 80 will ordinarily extend to the tank or reservoir of compressed air and the pipe 38 will lead to the distributer which may be the form shown in Figs. 1, 2, and 3, or of some other form, and the pipe 18 will lead to a pump or air compressing device so that when the valve is moved into shaft journaled in said bearing aperture,

said shaft and casing being provided with a relief passage communicating with the atmosphere, a disk valve engaging said face and provided with a port extending through the Valve, and with a separate relief recess on the inner face of the valve adapted to register with a port-or ports in the valve seat, and also with said relief passage, and means for admitting pressure fluid into said casing adjacent to the rear face of said valve.

2. In a disk valve mechanism, the combination with a valve-body provided with a plane valve engaging face having ports therein, forming a valve seat, and having a bearing aperture extending through the body to said face, of a disk valve engaging said face and provided with a port extending through the valve, and with a separate relief recess in the inner face of the valve, said port and recess being adapted to register with ports in the valve' seat, a shaft separate from the valve mounted in said bearing aperture, said shaft being provided with an annular recess connecting with the relief recess in the face of the valve, the
