SPECIFLDATION forming part of Letters Patent No. 529,156, dated November 13, 1894. Application tiled March 31,1894. 'Serial No. 505,835. (No model.)

To a/ZZ vwhom it may concern:

Be it known that I, CHARLES W. BECK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Water-Meters, of which the following is a specification, reference being had to the accompanying drawings, which are made a part hereof, and in which- Figure 1 is avertical axial section of a meter embodying the invention in its preferred form. Figs. 2 and 3 are side elevations thereof showing the parts in the different positions that they occupy at dierent stages in the operation of the machine. Fig. 4 is aside elevation of a portion of a meter embodying the invention under a slight modification. Fig. 5 is an elevation of the register with the front of the casing removed. Fig. 6 is an elevation of a portion of one of the valve stems. Fig. 7 is a plan view of the walking beam.

The object of the present invention is to provide an improved water meter, and the invention consists inthe features of novelty that are particularly pointed out in the claims hereinafter.

In the drawings 1 represents the cylinder, 2 the piston arranged therein, and 3 the piston-rod extending through the cylinder head 4 and surrounded by a suitable stuffing box 5. Secured adj ustably to the piston-rod by means of a set screw 6 is a tappet 7, which is preferably perforated for the passage of a rod S which is mounted so as to be capable of sliding endwise insuitable bearings 9, and which is intended to transmit movement from the piston-rod to the valve gear. To this end collars 10 and -11 are adj ustably secured to it upon opposite sides of the tappet 7, by means of set screws 12, and it is connected with the valves through the medium of the gearing hereinafter described.

13 represents the induction chamber with which the supply pipe communicates through an opening 14, and which communicates with the opposite ends of the cylinder through ports 15 and 16, surrounding which are valve-V seats 17. 1S is the eduction chamber with which the eduction pipe communicates through an opening 19, andv which communicates with opposite ends of the cylinder through ports 2O and 21, surrounding which are valveseats 22.

23 and 24 are valves located in the induction chamber and adapted to control the ports 15 and 16, respectively, and 25 and 26 are valves located in the eduction chamber and adapted to control the ports and 2l, respectively.

The valves 23 and 25 are coupled together by means of a stem 126 which passes out through an opening in the top plate 27 of the induction chamber and is provided with a laterally elongated slot-28 through which passes a pin 29 by which it is connected to one end of a walking beam 30 mounted to oscillate upon a shaft 3l journal-ed in standards 32 rising from the top plate 27.

The

valves

24 and 26 are coupled together by a stem 33 which passes out through an opening in the top plate 27, and is provided with a laterally elongated slot-34 through `which passes a pin 35 by which this stem is connected tothe other end of the walking beam 30.

36 and 37 are brackets secured to the interior of the cylinder and provided W'ith openings through which the stems y126 and 33 pass, respectively, whereby the lower ends .of said stems areheld against lateral movement, their upper ends being held by contactwith the margins of the openings through 'the top plate 27. lvided with a loop or eye 38 for the passage The valve-stem 33 is proof the piston-rod 3.

39 is an arm which is rigid with the shaft 31, and may be either integral therewithvor else formed of a separate piece of metal and attached thereto by any suitable means, these parts being shown in Figs. 2 and 3 as being integral, and in Fig. 4 as being of separate pieces keyed together. To the lower end of the arm 39 is pivotally connected one end of a link 40, the other end of which is pivotally connected to an arm 41 which is adj nstably secured to the rod S by means of a set screw 42. I The walking beamis provided at its'center with an opening 43 for receiving the lower end of a lever 44, which latterv is provided with an opening for the passage of the shaft 31 to which it is securedso as to be incapable of movement relatively thereto, by a set screw 45,"011 any other suitable device, and said le,

IOO

43 and adapted to be engaged by the lever 44, as hereinafter more fully described.

The operation of the device thus constructed is as follows: As shown in Fig. 1, the piston is at the centerof its stroke to the right, or in the direction indicated by the arrow. When in this position the tappet 7 comes in contact with the collar 10, and during the remainder of the stroke of the piston ro the rod 8 partakes of the movement of the piston. At the instant the piston has completed its stroke, the parts are in the positions shown in Fig. 2, the center of gravity of the weight 46 having been shifted from one side x5 of the vertical plane of its center of movement tothe other. When the parts have arrived at the positions shown in Fig. 2 the weight moves by gravity in the direction of the arrow in said iigure,and, operating through zo the shaft 3l, arm 39, link 40 and arm 4l, shifts the rod S from the position shown in Fig. 2 to the position shown in Fig. 3. This same movement of the weight also brings the lever 44 in contact with the shoulder 48 and shifts the Walking beam from the position shown in Figs. 1 and 2 to the position shown in Fig. 3, and this movement of the walking beam in turn shifts the valves from the positions shown in Figs. 1 and 2 to the positions 3o shown in Fig. 3. This shifting of the valves closes the ports l5 and 21 and opens the

ports

16 and 20, thereby placing the left-hand end of the cylinder (as shown in the drawings) in communication with the eduction chamber 18, and the right-hand end in communication with the induction chamber 13. Water being thus admitted to the right-hand end of the cylinder, the reverse stroke of the piston takes place and discharges the water from 4o the left-hand end into the ed uction chamber and through the opening 19 into the eduction pipe. As soon as the piston arrives at the center of the return stroke the tappet 7 comes in contact with the collar 11, and during the remainder of said stroke moves the rod,which, in turn,operating through the arm 41, link 40, arm 39 and shaft 3l, moves the weight from the position shown by full lines in Fig. 3 to the position indicated by dotted 5o lines in said ligure, thus shifting its center of gravity from one side of the vertical plane of its center of movement to the other. `The weight then falls by gravity to the position shown in Fig. Land in so doing shifts the parts to the position shown in Fig. l.

The capacity of the cylinder being known, in order to make this mechanism available asa water meter, it is simply necessary to apply to it a register having such connection 6o with some of the moving parts that each stroke of the piston will be registered. To this end I have applied a register 14S, which may be of any desired construction, but which is preferably constructed as shown. It has a train of registering

disks

49, 50, 51, upon the rst of which is an annular series of ratchet teeth 52 with which engages a paw153 having teeth meshing with said teeth 52, and held in engagement therewith by a spring 54 snrrounding the stem upon which the pawl is adapted to oscillate. The arm 55 of this pawl extends out through an opening in the casing, and is connected by a link 56 with a collar 57 that is mounted loosely upon the piston-rod 3, between the collar 5S that carries the tappet 7 and a second adjustable collar 59. These

collars

58 and 59 are so located that as the piston is nearing the completion of its stroke in one direction or the other, one or the other of them strikes the collar 57 and shifts the arm 55. Upon the rst registering disk 49 are a number of pins 60, which are engaged successively by a spring actuated pawl Gl secured to the inside of the casing, whereby said disk is prevented from moving at random.

It is manifest, however, that while this machine is useful and primarily intended for measuring the quantity of water passing through it,it is at the same time equally as useful as a motor. In order to make it available for this latter purpose, it is simply necessary to make suitable connections between the piston-rod 3 and the device to which it is desired to apply the power. I have not shown these connections in the drawings, because they will vary with the nature of the machine to which the power is to be applied, and, furthermore, they will readily suggest themselves to any one skilled in the art.

The foregoing description contemplates a valve-operating mechanism which is conditioned to operate by the movement of the piston, but which is in fact operated by a force which is not derived immediately from the piston-that is to say, the movement of the piston simply lifts the weight to such position that it can fall by gravity and in so doing shift the valves through the medium of the described gearing, the arrangement being IOO IIC

such that the Valves are moved after the i movem'ent of the piston has ceased. This is preferable but not essential. If desired the valves ma) derive their movement from the piston immediately, through suitable gearing, such, for example, as shown in Fig. 4. In this figure the lever 44 and weight 46 are dispensed with, and the Walking beam 30 is rigidly connected with the shaft 31 so that the former partakes of the movement of the latter. Here also the link 40 is dispensed with and the arm 41 engages the arm 39 directly, so that the latter partakes of the movement of the former. In other respects the machine shown in Fig. 4 is the same as that shown in the preceding figures, excepting that the collars 10 and 1l are located at such distance apart and in such relation to the tappet 7 that the latter comes in contact with one or the other of said collars an instant before the piston completes its movement in one direction or the other, as the case may be.

The parts are so proportioned that a very slight movement of the piston, say one-half inch, will suffice to impart a quick movement v to the valves which will shift them. It will be understood that unless the valves are moved quickly they may become balanced with all of the ports open and this, of course, would stop the operation of the machine.
