CARL J". VELEY AND LINCOLN S. DEAL, OF KALAIVIAZOO,

MICHIGAN, ASSIGNORS TO COMSTOCK AUTOMATIC PUMP COMPANY, OF COIVISTOCK, MICHIGAN, A CORPORATION.

PUMP.

Application filed April 15, 1914.

To (6% whom it may concern:

Be it known that we, CARL J. VELEY and LINCOLN S. DEAL, citizens of the United States, residing at Kalamazoo, Michigan, have invented certain new anduseful Improvements in Pumps, of which the following is a specification.

This invention relates to improvements in pumps.

The main objects of this invention are: First, to provide an improved pump which is especially desirable for use in pressure systems. Second, to provide in a motor pump an improved pumping jack. Third, to provide an improved motor pump structure adapted for pumping both hard and soft water which is automatic in its operation. Fourth, to provide an improved pump which is very quiet in its operation. Fifth, to pro vide an improved motor pump in which the driving connections are so arranged that the strains are balanced and friction minimized. Sixth, to provide an improved motor pump which is very compact and is comparatively simple and economical in structure.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

We accomplish the objects of our invention by the devices and means described in the following specification. I

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the pump cylinder 1 is arranged within the well and is shown, as is quite common portion of the well pipe. The plunger 2 of this cylinder 1 is provided with a ball check valve 3. A check valve 4 is provided below the plunger 2. On the upper end of the well pipe is a cylinder 5. The cylinder 5 is of larger area than the cylinder 1, the object of which will appear later. A piston 6 is provided for the cylinder 5.

The piston 6 is connected to the plunger 2 by means of the pump rod 7 so that the plunger and piston reciprocate together. The pump rod 7 is extended through the top of the cylinder 5 and connected to the cross head '8. The piston 6 is provided with a .downwardly opening check valve 9 which opens on the upstroke of the piston and closes on its downstroke, being held yieldingly on its seat by means of the springlO.

The upper end of the cylinder 5 is provided with an air inlet valve 11 which is practice, as :1

arms for the uprights.

opened. by the downstroke of the piston 6 to admit air to the cylinder 5 above the piston. This valve is closed on the upstroke of the piston so that the air passes through the valve 9 into the cylinder below the piston. The valve 11 is held yieldingly on its seat by means of the coiled spring 12. vent cock 13 is provided for the upper end of the cylinder. When this vent cock is opened air enters and passes from the cylinder above the piston as the piston reciprocates. The cylinder 5 is connected to the storage reservoir 1 1 by means of the pipe 1 5, the tank and connections being shown: in conventional form in: Fig. XV. I

The pipe 15 is provided with a check valve 1-6. On the upstroke, water is lifted by the plunger 2 into the. cylinder 5, and since the cylinder 5 is ofgreater diameter than the cylinder 1, air passes thevalve 9. On the downstro-ke, the air andwater is forced out of the cylinder 5 past the valve 16 into the tank 1 1. The air in the cylinder 5 below the piston serves as acushion. preventing shocks and. noise as the pistons move downwardly. \Ve thus secure a combined air and water pump which. maintains the desired pressure in the tank 1 1.

The cross head 8 is mounted to reciprocat-e upon. the front uprights 17 of the jack frame. The rear uprights 18 of the jack frame are supported by-a suitable'floor plate 1 9 having sockets rights.- The uprights 17 and 18' are connected by the H shaped horizontal frame members 22 having holes at the ends of their These uprights are preferably sections of pipe, as shown, and the frame members 22 are secured thereon by means of set screws 23.

The well pipe 26 serves as an anchor and support for the pump frame. The shafts for the driving and crank wheels are supported by a frame member 27 which constitutes the bottom: horizontal frame member of the jack frame. The member 27 is secured to the well pipe 26'- by means of a clamp comprising clamp members 28 and the clamping bolt 28. The uprights 18 extendthrough the frame member 27, which is secured thereto by set screws 24:. The crank wheel shaft 29 extends through member 27, there being a crank wheel- 30 on each end of the shaft. The pitman or connecting rods 31 are connected to the crank wheels by suitable crank or wrist pins 32. To regulate the stroke of the pump, the crank wheels are provided with a plurality of wrist pin bearings ferent distances from the shaft.

The driving wheel 3% is connected to the crank wheels by means of the belts 35, the hub of the driving wheel being provided with pulleys or belt wheels 36 for these belts' Belt tighteners are provided for the 21 therein for the up-' the frame 33 positioned at difthe wheel- 3a. A belt tightener is provided for the belt ll, the belt tightener consisting of a pulley if carriedbv the. forked arm 45 r which:ismounted on the shaft 80, asare the arms 38:. By this arrangement of. the parts described, we secure a. very compact and sim'ple'structure. V

The soft water pump cylinder 18 is supported by a pair of brackets extending between the uprights 17. These brackets consist of a pair of members 429 clamped together upon the pump cylinder 18 and the uprightsby. the bolts 50. The plunger 51 forthe cylinder as is provided with a pump rod which isco-nnccted to the cross head .8; Thus connected-,1 the pumps arezoperated together. The cylinder 18' is connected to the soft water pressure or storage by the pipe 54,-see Fig. XV-and to the cistern or supply 55 by the pipeeo. .The pipe 56 is provided with a check valve 5T shown conventional-1y only, the check valve being disposed between the supply and the connection of the pipe54 to the cylinder es. The pipe 541 is provided with a check valve 58 controlled bv an electromagnet, the valve stem 59 constituting the armature of such electromagnet. See Fig. XVI. pressure is supplied tothe-tank 53 through the pipe 60 connecting the tank 53 with the tank 14;. A return check. valve 61 is provided for the pipe 60.

The electric motor 40 is-controlled by the switch 62 operated by the "heat 63 in the pressure tank 14;, the switch 62'being opened by the rising of the float when the tank is substantially filled, thus stopping the motor, the switch being connected to themotor through; the circuits 6%. hen the water withinthe tank 14; fallsbelow apredetermined point, the float falls, closing the switch 62 and starting the; motor. The plunger 51 is,

tank 53' Air under 7 of course, owing to its connection to the cross-head, operated whenever the cross head 8Eis operated,

The soft water pump lsrenderedinoperatlve for pumping water by the opening-of the valve58 in 'theconnection-M: for the reai son that, when this valve is opened, the water travels-from the cylinder 4:3 into the pipe 54 andback to t "6' cylinder as the plunger reciprocates. The, valve 58 is auto; matically held open by the electromagnet,

the delivery of current to the magnet being controlled by the float in the tank 53 which operates the switch 66 of the circuit 67, the switch being open when the water within the tank is below a predetermined point and closed when it is at this point. lVith the parts thus arranged, when the Water fills the tank 53 to the desired point, the float operates to close the switch and the clectromagnet is thus operated to hold the valve 58 in its open position, thereby rendering the soft water pump inoperative as the water merely passes from the cylinder into the pipe as and vice versa. A safety valve 68 is provided for the tank 53, the

safety valve being automatically opened, al-

lowing the air to escape,.when the pressure within the tank exceeds a predetermined point. The water is drawn from the tanks through the house systems 69 and 70, which are shown only in conventional form in Fig. XV. lVhere an alternating current is used the electromagnet is preferably supplied through the induction coil 71 connected to the motor circuits 64.

To lubricate the crank pins 32 and the crank wheels 30, the wheels are formed with oil chambers '75 which embrace the crank pins and also the ends of the shaft :29. The shaft is formed hollow and provided with lubricant openings 76 communicating with the oil chamber 75. See Fig. III. The idle bearings 33 for the crank pins are closed by plugs 77 which prevent the escape of lubricant from the lubricant chamber 75. The oil is introduced through the shaft which is provided with an oil hole 78. See Figs. II and IV. By providing this lubricating means for the bearings, very little attention is necessary. The driving wheel 34 is lubricated by providing its hub with a chamber 79 which is filled with a suitable absorbent material adapted to retain the lubricant. The shaft 80 is supported on the arms 81 of the frame member 27, the arms having holes 82 therein for the shaft. See Fig. VII. Set screws 83 clamp the shaft against the spaced rest Between the arms 81 and the ends of the hubs are thrust collars 85 which are flared at their inner ends as at 86. The ends of the hub of the driving wheel are chambered to receive the flared ends of these collars and provided with oil openings connecting the chambers and the oil reservoir. The chambers are expanded i11- wardly and the oil passages are disposed so that the centrifugal force tends to carry the lubricant back into the oil chamber 79.

Eur improved pump is automatic in its operation, and is substantially noiseless and without vibration, which is a feature of very great advantage as it is especially designed for use in residences although advantageous for use elsewhere. The pressure is automatically maintained ethat is, air

and waterare simultaneously pumped if desired-so that the water is under pressure and may be delivered to any part of a house system as desired.

We have illustrated and described our improved pump in a practical embodiment. lVe have not attempted to illustrate or describe various modifications which we contemplate, as we believe the disclosure made will enable those skilled in the art to which this invention relates, to embody or adapt the same as may be desired to meet the particular conditions. We desire, however, to be understood as claiming our improvements specifically in the form illustrated as well as broadly within the scope of the appended claims.

Having thus described our invention what we claim as new and desire to secure by Let ters Patent is:
