PUMP.

Application filed October 10, 1921. Serial No.. 506,547.

To all/071cm` t may concern:

Be it known that I, EDWARD J. DE VILLE, a citizenof the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new rand useful Improvements in Pumps, of which the following is a specification, reference being had therein tothe accompanying drawing. K l

y This invention relates to pumps, and more particularly to domestic pumps of the deep well variety and the objects seek toaccomplish are 'I First, the provision of mechanism by which I am enabled to use a high speed motor, such as an electric motor, with a low speed pump, whereby the high rotary speed ofthe motor is transformed into slow reciprocating motion and applied to the slow moving piston rod of such ,ya pump. l

Second, the division of the power headI into a base section to receive the water, a second section to yform an enclosure for the operating mechanism and a third section made removable to aord access to the bearings of the crank shaft, as also a support for the motor.

` ln the accompanying drawings forming a part of this specication: v

Fig. 1 is a partial side elevation and sectional view of my improved pump.

Fig. 2 is a vertical sectional view `ofthe same, showing the motor in elevation;

Fig. 3 is an enlarged vertical sectional 735 view of the upperportion of the casing showing the driving and driven sprockets, driving chain and oiling arrangement, taken on the line 4 4 of Fig. 1 and looking in the direction of the arrows;

`l:|`ig.-4 is a vertical sectional view of a part of the upper portion of the casing illus trating the driving worm and driven worm, crank shaft, worm gear and oiling arrangement, taken on the line v5 5. of Fig. 2 and `looking in the direction of the arrows;

The numeral 1 designates an electric motor.

of any ap roved commercial type capable of developing high speed so as to rotate the driving sprocket 2, say 17 50 revolutions per minute, or such a matter.' This motor is mounted on the upper section 3 of my improved power head and this section in turn is fitted upon an intermediate section 4 to which it is( connected, as by bolts or screws l 5. Panels 6 in the nature of doors are made removable so as to give ready access to the interior of this section at one side or the other; or the whole section may be lifted 0E byI removing the screws or bolts 5, which will be the case in exchanging one size of crank and crank shaft for another and in exchangingone length of connecting rod section for another, as will hereinafter appear.

This intermediate section 4 consistsof a shell-like structure havinga removable plate 7 which leads into a compartment 8 enclosed by walls 9, made integral with the remainder of the section. This intermediate part also contains a compartment 10 enclosed by walls 11. A depending wall 12 from the. upper section completes the enclosure of the compartment 10 which extends into the upper section. And it will be seen that an intermediate compartment 13 results from the presenceof the walls 9, 11 and 12.

The lower portion of the section 4 has removable door-like plates 14 adapted to close an opening 15 and which when removed gives ready access to the operating parts within. The base section designated 16, to which the section 4 is secured, as by bolts 17, comprises a hollow structure into which the water is delivered from the water cylinders. The channels within this base are designated 18 -where the water venters and whence it passes through a valve 19 into the circular chamber 20 and from which it issues through either or both of the discharge openings 21 to which water pipes may be connected. A central opening 22 in the base section is closed by a cap 23 to which the upper `or plunger cylinder 24nis secured and which is held by screws-25, permitting of the removal of the cap for withdrawing the pump pistons .and piston rods should occasion require, as hereinafter explained. The upper wall of this section 16 is fashioned with oil basins 26 `into which the cross head dips to distribute a lubricant on its guides, as will be presently explained.

The upper wall of the section- 16 is also provided with an opening 27 into which is fitted thel ain pump block 28; and an opening 29 over which is secured an air chamber 30 which communicates through the open- 105 in 29 .with the chamber 20 in the base 16.

o this base is also attached the drop pipe 31, as by bolts 32. This pipe extends down into the casing of a bored well, or into any .other type of well, such distance as the par- Mo ticular installation may Theupper or so calledy plunger cylinder '24 depends into vit, while the lower or lift cylinderl 33is l0- cated near the base of it,'as by being connectedfwith a valve seat spider 34l carrying a check valve 35 which lifts on the up-stroke and seats on the down-stroke. lA conventional strainer 36 is usually attached to the foot ofthe drop pipe. i y

rlhe pisten-rod 's usually made in two or more sections 37 and 38, coupled together in any well known way. The lower section 37 .carries a conventional piston or socalled lift bucket 39 with the usual check valve@ 40. And the upper section 38 carries a common-kind of piston or plunger 41.

, Thus the --water pumps are constitutedn v Referringgnow to the mechanism for operating-the water pumps'and the airpump, after which l shall give a description of the air pump itself, it will be noted that guides in the form'of rods 42 are mounted within the middle .section of the head with their lower ends located in the ylubricant' basins 26 and their upper ends in the sockets 43. On these guides l mount across head 44, Vthe j lower tapered ends of which are ada ted to enter the lubricant basins 26 and pic up oil for lubricating the' guides. vThe cross head is' secured to the upper section 38 of the water pump piston rod which passes through the bore 46 of the head and is supplied with nuts 47 above and below.

And to the cross head is also connected the lower section 48 of the connecting rod which in any convenient way is detachably fastenedto the upper sectionl 49, as by an overlappedjoint seen at 50, with the parts y caps 53. v

section 4 of the power head.` The. crank shaft carries a disk 61 to which is attached a worm, gear rim 62, as by screwsA worm pinion 64 mounted on a drive'nlshaftv 65 meshes with the worm gear 62 and rotates it through motion received by the 'shaft 65 from the `-sprocket 66 generally located in they compartment 10, but extended down into a sump" or well 10a. A; driving 'chain 66 islocated within a housing 66"v built on to and above the upper section 3. This housing extends over and receives within itthe motor A driving sprocket 2. By these several means the driving sprocket 2, the driven sprocket 66 and retenes the driving chain 66a are all -enclosed and kept dust free, as also lubricatedl in the manfrom the chamber l() and sump 10?1 unless the lubricant were returned as used. I"ll`o this end there is formed within the housing 661 p an oil compartment 10@L which receives lubricant from the chain and housing above it.

The lubricant runs back to the compartment 10 and sump 101L through a spout 66d. vAll this is clearly seen in Fig. 4.

Referring' to Fig. 5 it will be seen that above theV sump 10a extends a partition 10b n' with a small orifice 10c to establish communi-l s cation between the sump and the compart- 'llhis partition prevents the ment 10. sprocket 66 and chain 66a from drawing the ylubricant, more rapidly from the. compartment 10 than it returns thereto, by reason of the orifice 10` permitting the lubricant from passing more rapidly into the sump l()a than it returns to the compartment 1.0 through the spout 66d.- y.

The shaft 65 has suitable ball bearings in the walls of this section, as`.shown at 65a in Fig. 5. 'l

rlhe lubricant in the compartment is also taken up by the worm 64 and utilized in lubricating both the worml and worm gear.

It will be noted that the driving sprocket 2 of the motor is small compared with the diameter kof the driven sprocket 66 and that in turn the worm`pinion 64 is small compared with` the worm gear 62. ln the proportions shown, when the motor has a speed of 1750 revolutions per minute the worm 64 will revolve at600 per minute and the crank 55 at but 45 revolutions per minute. Thus,

a high speed small motor, economical in cost and current consumption may be used to y Aoperate my pump with its heavy water loads and strokes of pistons varying from four to six and eight inches with a crank l55 with a radius of two, three or four inches. These figures are examples which conform to what my assignee, the. manufacturer of this apparatus, is vcommercially practicing with this invention.

yReferring again to the connectin rod and to the objects in formingit in detac able sections, it .will be understood that two essential results are thus-accomplished.

c First, this permits of the use lof cranks of different radius or throw without interfer-` ing with the suii'icient descent of the cross head to take up the lubricant. from the basins 26. When a short crank is used a 'longer section, say section 49, ofthe con nectmg rod lis employed so that whenthe crank is down the rod is still long enough to let the cross head enter the basins. When a longer crank is used a shorter section, say section 49, of the rod is employed. This still permits the cross head to enter the lubricant basins.

Second, pumps whose pistons are of different lengths of stroke may be used with this power'head by shortening or lengthening the connecting rod to agree with the length of the crank employed for the particular stroke of the particular pump.

Referring now to the air pump which is used to force air along with the water supplied by the water pump into the storage tank .from which the water is to be forced bythe expansion of the air through the distributing pipes, as in a house, it will be seen that this air pump consists of a cylinder 67 open at its upper end and fitted at its lower portion in the block 28. Within the block is a valve seat 68 against which closes an air valve 69 by means of a spring 70 located in a cage 71. When the valve 69 opens downward air passes by it and through the cage into the chamber 20 and joins with the water in going to the pressure tank. rIhe valve seat 68 is grooved at 7 2 so as to always communicate with a` passage 73 and through an orifice 74 with the interior of the air cylinder. As the passage 73 joins with a passage 75 which leads to a pet cock 76, the air forced by the pump may be diverted and discharged without passing into the chamber 20, as will be the case when it is not desirable to pump any further supply of air into the storage tank. The pet cock 76 may be located within the section 4 of' the head, as would be the case with the cock located as in Fig. 4, or it may be connected to the block 28 by an intermediate pipe 77, as seen in Fig. '1, and in this case be located out, of the power head.

rIhe air pump piston rod 78 has at one end a piston 79 which on the up-stroke collapses or recedes enough from the cylinder to allow of the accumulation of air under it, while on the down stroke it expands against the cylinder and forces the air out of the cylinder. This rod is operated by a connection with the cross head through an arm 8O and nuts and lock nuts 81 above and below the arm. The arm is detachably connected to the cross head, as by a screw 82.

Thus the same cross 'head and power which operate the water pistons voperate the air piston; and the same relation rof speed as between the driving mechanism and the water pistons is maintained with reference to the air piston.

The air chamber 30 is connected by a pipe 83 to the wall 9 of the section 4 of the head and opens into the compartment 8 and enables the air to act o n the electric switch generally designated at 84. The air acts on the diaphragm 85 of this switch in the manner set forth inamy copending application filed Aprily 7th,1921, ser. No.. 459,268. I will not, therefore, describe this matter in this specification. It is sufficient to say that when a predetermined degree of pressure is created in the storagcftank the airunder compression in the air chamber 30 will react and operate this .switch or circuit breaker to cause it to open the circuit and stop the operation of the electricI motor. Andl likewise, when the pressure in the tank has been lowered vsutliciently v the switch or circuit `breaker will automatically act through the spring 85a and cause a closing of the circuit to restore the motor and' the pumping of air and water. l

It is sometimes necessary to withdraw the water pistons and piston rods in these pumps, as for repairs. v My construction readily permits of this. Simply disconnect the cross head from the a-ir pump piston rod, disconnect the sections of the connecting rod and disconnect and remove the section 4 of the power head from the base and remove the lcap 23, and then the water pistons and piston rods can be Areadily removed. The upper cylinder 24 will go with the cap 23.

It-will now be seen that my invention comprehends an electrically operated pump possessing numerous features of vmarked advanta e and practical utility. 4 y
