COMBINED METER AND VALVE.

To aZZ "whom it may concern:

jects of the invention is to provide im-,

proved means adapted to be set or adjusted with respect to the valve for tripping or releasing the valve when a predetermined quantity of the liquid has been discharged. A further object is to provide improved means whereby the valve tripping mechanism may be rendered inactive to permit an unlimited supply of liquid to flowthrough the meter without releasing the value.

A further object is to provide improved means for registering the amount of liquid which has passed through the meter, and improved operating mechanism for the register. A further object is to provide improved means whereby portions of the casings may be removed to permit ready access to the mechanisms and an improved manner of assembling and mounting the operatinggears and shafts whereby portions of the operating mechanism will be removed with the casing sections and without dismantling the said mechanisms.

A further object is to provide an improved device ofthis character which will be sim ple, durable and cheap in construction and effective and efficient in operation.

To the attainment of these ends and the accomplishment of other new and useful objects, as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating an exemplification of the invention, and in which Figure 1 is a side view, partlyin elevation, partly in section and with parts broken Specification of Letters Patent.

away, of an improved meter and valve of this character constructed in accordance with the principles of the invention. Fig.

2 is a top plan view of Fig. 1. Fig. 3 is an enlarged detail sectional view on line 33 of Fig. 1. Fig. 4.- is a sectional view on line H of Fig. 3. Fig. 5 is a detail sectional view of the connection between the register operating mechanism and the operating shaft therefor. Fig. 6 is a sectional view on line 6-6 of Fig. 5. i

Referring more particularly to the drawings and in the present exemplification of the invention, the numeral 10 designates a casing which may be of any ordinary and well known construction and is provided with an inlet opening 11 and a discharge outlet 12' in the form of a nozzle, and which outlet is provided with an air opening or vent 12*. Within this casing 10 is mounted a rotary pump which may be of any ordinary and well known construction but whichf;

forms no part of the present invention,

sufiice it to say that when the handle 13,

which is secured to the shaft 14, is rotated, the pump will be operated to draw the liquid into the inlet opening 11 and discharge the same through the outlet opening 12.

Arranged within the discharge outlet is a partition 13 which extends across the outlet, as shown, and is provided with an open- 1 ing 14 with which opening a valve 15 cooperates. This valve 15 is provided with a stem 16 on one side thereof which is adapted to move in a bearing 17 formed in a cap nut 18, which latter engages a threaded aperture 19 in one of the walls of the outlet. An elastic member 20 such as av coil spring or the like, is provided, one end of which preferably surrounds the stem 16 and has engagement with one face of the valve 15. The other extremity surrounds the bearing 16 and rests within a recess 21 in the nut 18. This elastic member 20 normally exerts its tension on the valve 15 to seat the latter. The bearing 17 preferably opens through the nut 18 and the end of thestem may be provided-with a groove 22 so that an instrument, such as a screw driver or the like, may be. inserted into the .bearing 17 and the valve 15 rotated upon its seat so as to grind the valve and seat.

bearing 17.

extremity 27 of the stem 28 on the other side of the valve 15. This stem 24 may be of any desired length and projects for any desired distance above the top of the casing.

The free end 29 of the stem passes through a suitable hearing 30 and is provided with a shoulder 31. The stem is adapted to be reciprocated in the bearing 30 and the nut or bushing 26, so that when it is movedin one direction it will open or'unseat the valve 15 and when the valve 15 is moved in the opposite direction by the tension of the spring 20, the stem 24 will move in its bearings to permit the valve 15 to close.

Any suitable means may be provided for adjusting the stem 24 to open the valve 15 and for this purpose the stem 24 may be provided with a collar or shoulder 32 which is adapted to be engaged by a projection 33 on a lever 34 which latter is pivotally mounted as at 35 to a suitable support 36.- When the handle or lever 34 is depressed, the projection 33 will force the collar 32 and the stem 24 downwardly to move the valve 15 against the tension of the spring 20. This movement of the stem 24 will also move the shoulder 31 to a position to be engaged by an arm or lever 37 which is pivotally supported as at 38 so that the stem will be locked in a depressed position and the valve 15 will be locked in an open position. The arm or lever 37 may be provided with a handle 39 whereby the former may be operated about its pivot and an elastic member 40 may be provided, one end of which engages an extension or projection 41 on the arm or lever 37 and the other end engages a fixed support and tends normally to move the arm or lever 37 in a direction about its pivot to pass over the shoulder 31 on the stem 24 when the latter is depressed to antomatically lock the stem in this position. In order to hold the lever 34 me position convenient to the operator or in a raised position, it is provided with an extension 42 arranged on the other side of its pivot 35 and this extension engages a tubular member 43 which telescopes into a bearing 44 on a fixed support, preferably the support 36. An

elastic member 45 is provided between the member 43 and the bearing 44, which tends normally to extend the member 43 with re.- spect to the bearing 44 so that the member 43 will engage and depress the extension 42 of the arm or lever 34. It will thus be seen that before the pump is operated, the valve 15 must be opened by depressing the arm or lever 34 and when depressed the arm or le ver 37 will pass over the shoulder 31 to lock the valve open. This arm or lever 37 may be operated either by the handle 39 or the spring 40. With the valve thus locked open, the handle 13 is operated, which will operate the pump and draw the liquid into the inlet opening 11 to force the same through the outlet opening 12. This operation may be continued until the arm or lever 37 is switched about .its pivot to release the stem 24 which may be accomplished through the medium of a handle 39. The specific construction of all of the above described parts, however, form no part of the present invention but constitute the subject matter of a separate application filed by me in the United States Patent Ofiice June 19, 1908,

Serial No. 439,398.

It is one of the objects of the present invention to associate with this mechanism improved means whereby the valve 15 may be automatically released during the operation of the pnmp when a predetermined quantity of liquid has been discharged, which quantity may be varied by the adjustment of the releasing mechanism which will now be described.

The motor shaft 14 to which the handle 13 is connected is provided with a gear 46 which gear is connectedto a stub shaft 47 through the medium of a train of gears 48, 49, 50,51, 52. This latter gear 52 is secured directly to the shaft 47 for rotation therewith in any desired or suitable manner and all of the gears 48 to 51 inclusive are mounted on suitable bearings 53 (see Fig. 3) and which bearings are secured in any desired or suitable manner to the outer face of a removable portion 54 of the pump casing 10. This section 54 is secured to the casing in any desired or suitablem-anner, preferably by means of the ordinary and well known fastening bolts 55 which pass through the member 54 and into the casing. The shaft 47 is adapted to pass through a suitable opening 56 in the flange 57 of the pump casing 10 and into which flange the fastening bolts 55 pass. This shaft may be of any desired or suitable length but is of a length sufficient to project slightly beyond the flange 57 on the side opposite to the side on which the section 54 of the casing is secured. This free extremity of the shaft 47 is enlarged as at 58 and is provided with one or more bifurcations 59 (see Fig. 3). A supplemental cover or casing 60 is provided, which is provided for inclosing the gears 48 to 52. This supplemental casing 60 rests against the outer face of the section 54 of the pump casin 10 and is removably secured in position y means of suitable fastening devices 61 which pass therethrough and into the section 54. The supplemental casing 60 is also provided with an opening in its top 62 through which the shaft 14 of the pump passes so that when it is desired to gain access to the gears 48 to 52, all that is necessary is'to remove the handle 13 from the shaft 14 and also remove the fastening devices 61 when the casing 60 may be lifted out of place. If desired, the section 54v of the pump casing may be removed without removing the casing 60 when it is desired to gain access to the interior of the pump casmg.

Journaled in suitable bearings 63 on a fixed support such as the top of the pump casing 10 and extending transversely of the casing, and in line with the shaft 47 is a shaft 64 which is provided with one or more lateral projections 65 adjacent one end and this end is arranged with respect to the pump casing in such a position that when the section 54 of the pump casing is placed in position, the enlarged end 58 of the shaft 47 will receive one end of the shaft 64 and the lateral projections 65 on the shaft 64 will enter the bifurcations 59 in the portion 58 so that when the parts are thus assembled and the handle 13 operated, to rotate thegears 48 to 52, the stub shaft 47 will be rotated and this shaft will in turn impart a rotary motion to the shaft 64. The tripping mechanism or the mechanism which is adapted to directly engage and operate the arm or lever 37 is controlled by the operation of this shaft 64 in the manner which will now be described.

Arranged on the shaft 64 is a worm gear 66 which meshes with a gear 67 and this gear is arranged to rotate about an upright pivot. The gear 67 is provided with a hub 68 which is hollow as at 69 and is provided with notches arranged opposite to each other. A shaft 70 is rotatably mounted in the portion 71 of a casing designated generally by the reference numeral 72, and this shaft is adapted to project into the hollow portion 69 of the hub 68 of the gear 67. The shaft 70 is provided with lateral projections 73 preferably in the form of a pin which passes transversely throughthe shaft adjacent its extremity so that when the said extremity enters the hollow portion 69 of the hub 68, the projections formed by the pin 73 will enter the notches in the hub so as to lock the shaft 70 for rotation with the gear 67 This shaft 70 projects beyond the portion 71 of the casing 72 and is provided with a tapered or conical .portion 74. A cam 75 is provided with a conical aperture 76 therethrough which is adapted to receive the conical portion 74 of the shaft 70. The shaft 70 projects beyond the cam 75 and is preferably reduced as at 77 and a locking cam 78 is pivotally supported by the ex tremitry of the portion 77 of the shaft 70. A collar or washer 79 is also provided which surrounds the reduced portion. 77 of the shaft 70 between the cams 76 and 78 so that when the cam 78 is rocked about its pivot 80 in one direction, the collar or washer 79 will force the cam 75 onto the conical portion 74 of the shaft 70 and will lock the cam 75 for rotation therewith. When the cam 78 is adjusted in a direction to move the high portion of the cam out of engagement with the collar or Washer 79, the cam 75 will be loose with respect to the shaft 70 and the conical portion 74 thereof and the shaft 70 will rotate independentlyv with respect to the cam 75 when the latter meets an ob struction inits path of movement.

v The arm or lever 37 is provided with an extension 81 on the extremity of which is preferably mounted an anti-friction roller 82 and this roller 82 is arranged within the path of movement of the cam 75. It will thus be seen that when the valve 15 is locked in its open position in the manner already set forth, and the cam 75 is unlocked with respect to the shaft 70' so that the shaft 70 will rotate independently with respect thereto, the handle 13 may be operated to operate the pump to discharge any amount of liquid through the outlet 12 and this operation may be continued as long as the supply of liquid lasts and until the lever tion to engage the shoulder 31 on the stem 7 24, the anti-friction roller 82 on the extension 81 of the arm or lever will assume a position to be engaged by the cam 75. If ;the cam 75 is loose on the shaft 70, it will be apparent that even though the cam 75 is carried around with the shaft 70 by imeans of its frictional engagement therewith, even when the cam is unlocked, its motion will be arrested as soon as it strikes :the anti-friction roller 82 without tripping the arm or lever 37. \Vhen it is desired to automatically trip the lever 37, the cam 75 is first adjusted to any one of the graduations or indications 83 on the pump casing 10 and which graduations or indications are provided for, indlcating the amount of liquid which will be discharged by the meter or pump during the time that the cam 75 will move from such graduations to a point 'to engage the anti-friction roller 82 and ;trip' the arm or lever 87. When the cam 75 is thus adjusted, the cam 78 may be moved about its pivot 80 so as to force the collar or washer 79 against the cam 75 so as to bind or lock the cam 75 for rotation with the shaft. When thus locked, and when the valve 15 is locked open, it will be apparent that as the cam 75 advances to engage the anti-friction roller 82, a further advancement of the cam will force the lever 37 about its pivot 38 to move the lever out of engagement with the shoulder 31 to automatically release the valve 15 and when so released the elastic member 20 will close the valve.

In order to register the amount of liquid discharged, a register 84 is provided in the form of the ordinary cyclometer provided with an operating shaft 85 and this shaft 85 receives its motion from the shaft 64 ously, the gears 86, 87,'are properly proportioned with respect to the rotation of the shaft 64 and the discharge of the liquid.

- In order to permit the shaft 64 to be rotated in a retrograde movement, an'd at the same time prevent injury to the registering mechanism, a loose connection isprovided between the gear 87 and the shaft 85 (see Figs 5 and 6). This connection comprises a pawl 90 which is housed within the gear 87 and coiiperates with a shoulder 91 on the shaft 85. An elastic member 92 is provided which tends normally to move the end of the pawl 90 in a direction to engage the shoulder 91 on the shaft 85. When the shaft 85 is rotated in one direction, the gear 87 will be locked for rotation with the shaft but when the gear 87 is .rotated in the opposite direction, the pawl 90 will move out of engagement with the shoulder 91 and ride over the shaft 85.

The casing 72 incloses the registering mechanism as well as the gears 67, 66, 86. and

87, and is provided with a sight opening 93 through which the registering mechanism 84 is visible. This casing is removably secured in position in any desired and suitable manner preferably by means of a lip or ear 94 which is adapted to engage under a shoulder 95 on the casing 10, and a fastening device 96, such as a bolt or the like, is provided which passes through an extension 97 on the casing opposite to the lip 94 and also into the pump casing 10. The sides of the casing 72 are provided-with openings 98 into which the bearings 63 of the shaft 64 project. When it is desired to gain access to the registering mechanismall that is necessary is to remove the fastening device 96 and lift the casing 72.. As the casing 72 is lifted, the lateral projections on the shaft formed by the pin 73 will be raised out of the notches of the hub 68 of the gear 67 to permit th casing to be readily removed. I

mamas It will be apparent that when it is desired to discharge a predetermined amount of liquid, the cam 75 will be first adjusted and then secured in position with respect to the shaft 70 after which the valve 15 may be opened and the handle 13 rotated. At any time it is desired to discharge an unlimited amount of liquid, the cam 7 8 is first shifted to release the cam 75.
