Specication of Letters Patent.

Application tiled September 9, 1911.

To all whom it may concern:

Be it known that I, WILLIAM L. Monnrs, a citizen of the United YStates, residing at Fort Wayne, in the'county of Allen and State of Indiana, have invented certain new and useful Improvements in Automatic c Valves, of which the following is a specification.

This invention relates to automatic valves more particularly designated and described as an automatic throttle valve, and used in connection with apparatus for maintaining fluid in a receptacle at a given level.

The principal object of the invention 1s to provide an improved, simple and cheap device o'f' the clasps described which shall be effective and efficient in operation.

For the attainment of these ends and the accomplishment of other new and useful objects, as will appear, this invention consists in the features of novelty; in the construction, combination and arrangement of the several parts generally described in the specication and shown in thedrawing, but more particularly pointed out in the appended claims.

ln the drawing, Figure 1 is a view partly in section of a valve and the preferred construction ofy an apparatus for operating it;V Fig. 2 is a detail cross-sectional view on the line 2 2, Fig. 1; Fig. 3 is a detail sectional view of a valve wh1ch operates oppositely to the valve shown in'Fig. 1.

ln maintaining a Huid in a tank at the proper ievel, it is frequently desirable to 1n action for accomplishing the desired result. lt may be that it is desired to pump liquid into the tank or from the tank or' recegtacle to some other place. v

his invention has 'for its object to probe re lated` and adjusted to effect either one oL these actions with a single valve.

\ Referring now more particularly to the drawing, and in the present exemplication o this invention, a portion of a tank r certain height therein, and a oat 12 supported in the liquid. Connected to the reeeptacle is a pump 13,- which has a steam inlet pipe 14 controlled by a valve 15. This valve- 15 is of any desired or suitable construction, and preferably has avalve stem 16 movable into and out ofthe valve caslng, and operative to position the valve disk 17 upon the valve seat 18.

Attached to the valve 15 in any desired 0r suitable manner, such for example as by threading it u on the valve casing, is a frame 19. Thls frame is preferably composed of metal and is formed with a bifurcated extremity 20 and a guideway 21 intermediate of the ends. A guide 22 is secured to the valve stem 16 and is-adapted to slide in the guideway 21. At the outer end of the guide 22 are pivotal bearing members 23 which are adapted to provide apivotal mounting or the in 24 and the wheel or roller 25.` The bi rcated extremity 20 is adapted to provide a pivotal mounting for `theroller 26 which has a pivot pin 27 extending from the sides thereof. Positioned between the rollers and 26 are resilient members or springs 28 which are preferably secured to the extending pivot pins 24 and 27, and the tendency of these springs is to draw the roller 25 toward the roller 26.

Secured to the float 12 is a rod 29, and

adjustably secured to the rod is a member 30. This member 30 is preferably formed with a groove 31 on one side, at the ends of which are collars 32 and fastening screws 33. The rod 29 is adapted to be inserted in the collars 32 to be positioned along the groove of the member 39 and to be adjustabl locked in position by means of the loc ing bolts 33. The other side of the member 30 is formed with an inclined face 34 to 'vary the width of the member 30 from one end tothe other. The rod 29 and the member 30 are positioned between the rollers 25 and 26, so that the latter bears against the rod 29 and the :tace 34 bears against the roller 25. It is evident that as the member 30 is moved through the bifurcated extremity of the frame v19, and relatively thereto between the rollers 25 and 26' that theroller 25 and the uide 22 will be moved in accordanceiwith t e movement of the member 30. In* other words', the valve stem and the valve will be opened or closed in'accordance with f steam against the valveV is considerable, and

if the Weight of the float 12 is not sufficient to move the member 30 downwardly, as shown in Fig. 1, the valve Will beheld open. Tocounteract lthis tendency and to equalize the pressure i1' 'vided adjustab e weights 35 Which are preferably positioned upon'the rod 29.

In the exemplification of my invention" shown by Fig.

1the pump 13 maintains a constant leve in the receptacle 10 by pump- 'ing fluid from thereceptacle'. It is evident that by reversing the member 30 so that the widest portion is located at the bottom that the pump 13 Will be actuated by-means of the valve 15 to maintain a constant level in the receptacle 10 by pumping fluid to the receptacle. It is also evident that a valve 36 such as shown by Fig. `3, in which the valve disk 37 is drawn outwardly by the valve stem 38 to-close the valve, may also be used in connectionv with the apparatus shown by Fig. 1. With thiskind of o erating mechanism the action of the va ve is entirely automatic and no attention need be paid to the operating mechanism. It is also evident that the valve 15'may be useddirectly to control a flovvv of fluid through the valve to a tank or receptacle in which the float 12 is located; -In this case, to maintainthe fluid at a given level it would benecessary to have the member 30 reversed.

While I have thus described the preferred construction, combination and arrangement of the several parts which constitute my invention, it is evident that others may make various changes Without departing from the spirit'and scope ofi my invention.

What I claim is:

1. The combination With a valve, of an adjustable member With an inclined surface movable relatively to the valve, means to support said member in its adjusted position, and operative connection between `the v "member and the 'valve to open and close the latter in accordance with the movement of the member. i

2.' The combination with a valve, of a rod movably supported adjacent the valve, a member graduated in width adjustably positioned on and movable With the rod relatively to the valve, 4and means supported by the valve and having connection with ythe said member to operate the valve in accordance with the movementof the rod.'

3. The combination with a valve having a valve stem movable therein, of a frame attached to the valve, a member with opposite faces one of which is inclined adjustable and movable in said frame, and means bearing on the valve, there are pro-v resiliently upon one of said faces and operatively connected to move the stem in accordance with the movement of the said member.

4.
