APPARATUS FOR DISPENSING CLEANING FLUIDS.

Specification of Letters Patent.

Patented Feb. 14, 1911.

Application filed November 18, 1909. Serial No. 528,640,

To all whom it may concern:

Be it known that I, JOISEPH N. l 3. BoNn, a citizen of the United States, residlng 1n the city of New York, borough of Manhattan,

I machinery require thorough overhauling labor, and, in many instances, expert skill is and cleaning at certain intervals. According to the present practice, .the parts composing the motor or machine are separated or taken apart for such purposes, an'opera-- tion which involves conslderable t1m e and necessary for the the parts. j

proper ire-assemblage of The object of my invention is to obviate,

' in many cases, theforegoing objections, and

to this end I provide an apparatus adapted to be easily carried by a Workman and capable of dispensing, under pressure, a clean-' ing fluid'which will reach or penetrate into the crevices of the machineor motor for the purpose of flushing out the dust, oil, dirt and other matter which tends to clog up the working parts.

In a preferred embodiment of the invention, my apparatus comprises a closed tank constituting a chamber for the storage of the cleansing fluid, a pipe or hose at the bottom part of said tankfa nozzle on said pipe,

. a. faucet or like device for controlling the flow of fluid through said pipe, an air com- I pressor-or pump, and a pipe leading from saidcompressor or pump to the tank above the fluidlevel therein.

The invention will be hereinafter described more fully in connection with the accompanying drawings.

In the accompanying drawings I have illustrated one practical embodiment of the invention, but the construction shown therein is to be understood as illustrative, only, and not as defining the limits of the invention.

Figure 1 is a vertical longitudinal section,

partly in e1evatio-n,'of a dispensing apparatus embodying my invention.- Fig. 2 we cross section, partly in plan, the plane of the section beingindicated by the dotted line 2-2 of Fig. 1. Fig. 8 is a horizontal sect ion on" the line 33 of Fig. 1.

relation to the tank, the handle, may be A designates a tank which may be composed of sheet metal or any other suitable material. Said tank isprovided with a sub stantially. closed chamber, a, wherein a cleaning liquid of any desired character may be deposited. The upper head, a, of tank, A, 1s provided with a filling orifice, b, which is normally closed by a cap, B, whereby the cap may be-removed so that the cleaning liquid may be poured into chamber, a, up'to any desired level therein.

Attached to the bottom part of tank, A, is a cook or faucet, C, and connected to this faucet 1s a pipe or hose, D. Said pipe is, preferably, in the form of a flexible tube, and at the free end of the tube is a nozzle, (Z of any suitable construction.

In connection with the tank I employ an a rcompressor or pump, the cylinder,.e, of

which is positioned substantially cent-rally within tank, A. The lower part of the cy1- inder 1s fastened to a foot piece, a, by a liquid and air tight joint so that cylinder, 6, W111 not communicate with chamber, a, of the tank, whereby the liquid in the tank is precluded from flowing into the pump cylinder. Within the pump cylinder operates a piston,

'E, which may be of any suitable or preferred COIlSlSIlIClJlOIl, and attached to said piston is a rod, E, the latter extending upwardly above the head, a, of the tank. The pump cylinder is substantially closed at its upper partbya cap, f, the .latter being, preferably, screwed upon a projecting part of cylinder, e, and said cap, f, is provided with an aper ture, f, through which freely passes the piston rod, whereby the piston may be reciprocated, and air is free to flow through the aperture, f, into the pump cylinder. Suitable means are provided for the operation of v i the piston by hand,and in Fig. 1, the piston rod isshownashaving a handle, F, said handle being provided with a collar, g, the latter being attached to piston rod, E. The collar, 9, isprovided with a lockingplate, Gr, shown in Fig. 2, and opening through one edge of this plate is a notch, g, in which is adapted to fit a headed locking stud, 9 said stud being attached fixedly to the head or cap, f, of the pump cylinder. The handle, F, and rod, E, may be rotated by hand as well as moved endwise, andshould it be desired to lock the handle and piston in fixed turned in order to engage the notched plate, G, with headed stud, 9 whereby the entire apparatus may be easily carried by the handle, F. In order to reciprocate the' piston, however, handle, F, and plate, G, must be turned in ordercto disengage the notched plate from'the headed stud, and' at this time the handle may be operated for the purpose of reciprocating the piston rod and the piston. 4

Foot plate, 6, is provided with an air passage, h, one end of said air passage opening upwardly so as to communicate with the lower part of piston cylinder, 6. other end of theair passage opens'into a check valve chamber, h, which is providedin foot plate, 6', and communicating with this check valve chamber is (the lower bent part, i,"of an air tube,"I. A check valve, H, preferably of the ball variety, is fitted loosely: in chamber, h, so as to open in one direction when air is compressed bya down- -ward movement of piston, E,thus permit-- ting the air to flow through the piston cylinder into and through tube, I.

;The--,air tube is positioned, preferably, within chamber, a, 'of the .tank and it lies adjacent and parallel: .to piston cylinder, 6. The upperpart of the air tube is held firmly in position by suitable means, such as the 'brace, 71', and at its upper extremity the air tube is provided with a valve seat, This- .upper part of theairtube communicates with chamber, a, of the tank above the liquid level therein, and the air compressed 'in pump cylinder, 6, is-free to flow from the pump; cylinder through the foot plate, and. through tube, I, into the upper part of.

- chamber a..

J designates a needle valve, the lower tapering, end of which is adaptedto operate in the orifice provided in thevalve seat,

at the upper extremity of tube, 1. The

j, for conveniently operating the same.

- Should it be found that the check valve, H,

- 'leaks, the needle valve, J, "may beoperated to tightly'close the exit at the upperen'd bf tube, I, thus precluding the air stored un-- der pressure in the upper part of chamber, a, from leaking through tube, I, and into the pumpcylin'der; In lieu of employing aball and a 'suitable cleaning fluid is poured through" opening, I into chamber, a, of the tank, after which cap, B, is. replaced. Faucet, C, being closed, the pump 'or compressor is operated by hand for the purpose of establishing air pressure upon theliquid con- The F, is turned in a-direction to release notched plate, G, from headed stud, g and said handle is then operated to reciprocate rod,

E,'and piston, E. The air below said piston is compressed and forced through passage, h, and tube, I, the air escaping from s the upper part of the tube into chamber, a.

The piston is operated a proper number of times to establish the required pressure of air upon the cleaning liquid in the tank, and after this-operation the handle, F, may be turned in order to engage notched plate, G,

with stud, 9 for the purpose of locking the. handle and the pistonin fixed relation to the tank. The apparatus may be carried by the handle, F, or it may be placed beneath the arm of the operator. In using theapparatus, faucet, C, is opened, and the liquid is expelled from chamber, a, by air pressure sons to flow through tube, D, and nozzle, d. The cleansing liquid is ejected under pressure through the nozzle, and it will find its Way into the cracks, crevices and other inaccessible places .of a motor and variousother kinds of machinery which it is desired to clean. The cleaning liquid will flow out of the motor or other machine, and carry with it the dust, oil,- greas'e, dirt and other.

impurities which tend toclog the working parts of the machine and interfere with its working operation. I

The employment of a check valve, such as H or K, precludes the air under pressure in chamber, a, from flowing throu h pipe, I,

assage, h, andpiston cylinder, e, but should 1t :happen that the check Valve H, is defective, valve, J, is operated to tightly close the'opening in the upper part of tube, I,

whereby air under pressure in chamber,- a,

is precluded fromescaping through tubes, I,

and e. needle valveoperates in a suitable stufiing box, 7', attached to head, a, of the tank, and said valve is provided with a thumb wheel,

Any. suitable cleaning, liquid may be employed, such as kerosene, and this cleaning liquid may be easily introduced when cap, B, is removed. Under some circumstances I may omit the use-of-a cleaning liquid and dispense air from the chamber, a, the air 'beingifforced under pressure into the tank by the operation of the pump, the air being retained underpressure in said chamber, a.

When using the apparatus for cleaning purposes with air as the cleaning agent, valve,

the upper art of'tube, I," was to preclude the air un er pressure in chamber, a, from escaping through'the tube, I, and passage, h, into the piston cylinder, and then it is J, is adjusted to tightly close the opening in only necessary toopen the faucet, O, and

direct the current of airin tp theplaces to be cleaned by moving the nozzle, d, as required;
