This inventionrelates toan air. pump. and a cumulator. and more. particularly to. suoh-ad vice dapted. for use. in opening; clogged, drains. and thelike.
The. principal object, the invention, is the. provision. or an improvedformof; air. pump an accumulator.
A. further object of the; invention is the, provision. ofan. air pump and accumulator which may. be inexpensively formed. and advantageously. used due. to the novel. arrangement of therarts: thereon A. still further object of the,- invention is the. provision. or an. air pump, and. accumulator ine eluding; a normally closed outlet valve and means for. opening the: outlet, va1ve,0p.erable by. applying; pressure. on the. device to. simultaneously engage. the deviceonor. adrainopening andto open. saidvalva,
A. still further object. of. the; invention. is. the. provision. of an. air pump; and; accumulator, hebody. Portion; of. which acts as a uide for the; valve element ther.eof-..
A still further object of the invention isuthe, provision ofan air pump and. aocumulaton, the body portionofi which comprises an impact ex: trusion oi a. shape.- contributing to: the. operating efficiency of the device.
The; air pump and accumulator disclosedhere in comprises. an improvement in the artand partioularly with respect, to theconstruction, and. formation and assembly of parts, ofthe;deyic.e as compared with those devices heretoioresknown. in. the. art. The. air pump. and accumulator dis, closed. herein. also. d-iiiers considerably with. re,-: spectto the prior art in that it is so-;formed astoenableit to be engaged in a, drain outlet. suitable. pressure to; eiiect a seal. between the device and the drain outlet and the; motion necesssary tooperate the; devicezapplied tojthedevicain the same direction.- whereby; the device remains: securehz impinged. upon orin the drain; outlet. and avoids the-heretofore commona tendency. of mo d ing away from the drain outlet atthemomentotoperation.
In the. devices. heretofore known; in. the art. the accumulator portions included, release-valves op, erable by handles movable awayfronr the. point: of discharge of the". device. In utilizing the devices the tendency of the operator to move the device. away from the drain; opening; atthepreoi' e moment of discharge continually occurred with the result that only partially efiective results were obtained.
In; the present invention the valve arrangemfint,
is such that continuous and increasing pressure.
on the device in the direction of. the drain'ouir let inwhich the device is positioned is made possi-- ble. up to. and including the moment. of discharge; of the accumulated air in the device and at such time thereafter as any. air pressure exists in the accumulator. and/or. draineoncerned'.
W th. thaforesoine. and. other obj cts in view. which will, appear asthe. descriptionproceeds, the. invention residesthe: combination. and rrangement oi. parts and. in the. details or con.-
struction. hereinafter described and. claimed, it.
beingtheintentionto cover alllchangesand modifications. of the example. of the invention herein chosen for purposesoi the, disclosure, which, do.
not constitute. departures, from the spirit and;
scopeof theinvention.
The inventionis illustrated in the, accompanying drawing whereinrz.
Figure 1 is. a. side. view. of the, air. pump. and accumulator with; parts. broken: away...
FieureZ is at p p view or the-air. pump. and accumulator taken on line, 22. of; Figure, 1'.
Eigure3 is a vertical section. of the. air pump and accumulator taken on lin.e. 3..3., of, li igure 2.. By referring to theidrawings andE sures 1 a d'. 2 in particular it will. beseen, that the air pump.
with a. central. orifice. Iii hrou h. which a. valve rod I1 is. positioned. pac ing. glandv assembly t8. being positioned in the, orifice [6, about the, rod l1. to insure, the retentionof air pressure in. the, cylindrical body. H) which. forms the. accumulator portionpof the device.
The lower conical end ll. of the. cylindrical, body to; forms an annular valve, seat [9. at, its, point of discharge into. the. tubular, discharge end. [2' and a resilient valve member 29 carried on the lower end of the valve rod' IT is provided'for engagement with the valve seat, l9 to close theoutlet communicating with the discharge end l2: A pump cylinder 2| is provided and is positioned within the cylindrical body Ill as best shown in Figure of the drawings. The pump cylinder-2i is provided with an outwardly flanged upper end 2:2 which registers on a seat- 23' formed about a secondary orifice-24 in the top l5 and the pump cylinder 2| ismaintained in position by the presence of a nut 25 which in turn. is provided with holes 26 for the dual purpose oi admitting air to the interior of the pump cylinder 21 and providing means for engagement by a spinner wrench. A piston rodil'llis. positioned through a central opening 28 in the nut25 and is. provided with a piston 29 on its lowermost end and a handle 30 on its uppermost end. I
The lowermost end of the pump cylinder 21 takes the form of a tubular discharge pipe 3! over which a rubber check valve 32 is positioned;
The rubber check valve 32 is normally closed and air pressure built up within the pump cylinder 2| by reciprocating action ofthe piston 29 causes the same to open and discharge the air pressure into the accumulator formed by the cylindrical body of the device. An air pressure gauge 33 is positioned on the top l and communicates with the interior of the cylindrical body member through an orifice therein so that the air pressure built up within the accumulator portion of the device may be readily determined thereby.
By referring now to the lowermost discharge end 12 of the cylindrical body l9 it will be seen that a resilient fitting 34 is secured thereto and includes a passageway 35 through which the air pressure may be discharged into a drain or the like. The resilient fitting 34 is half-spherical in shape and includes an upstanding annular fiange 36 which enables the resilient fitting 34 to be distorted for air-tight registry with various sizes and shapes of drain openings and the like.
In order that the resilient valve member 20 may be moved upwardly and opened at such time as a suitable accumulation of air pressure is built up within the cylindrical body H! of the device, a handle 31 is provided for imparting movement to the valve rod l1 and is mounted on the top l5 by way of a bracket 38 to which it is pivoted by means of a pivot pin 39. The handle 3'! is formed with a projecting end 40 having an opening therein through which the valve rod I1 is passed and adjustment nuts 4! are positioned on the rod 11 above and below the projecting end 40. A spring 42 is caged between the underside of the handle 31 and the upper surface of the bracket 38 and normally urges the handle upwardly and the projection 40 thereof downwardly and thus normally biases the valve 20 toward closed position.
It will thus be seen that at such time as it is desired to operate the device, suitable air pressure is built up within the accumulator comprising the body by the air pump portion and the device then engaged upon the drain outlet or opening with the resilient fitting 34 being held in tight registry therewith by downward pressure brought upon the air pump and accumulator. Similar downward pressure is then exerted on the handle 31 which causes the valve 20 to move upwardly and permits the discharge of the accumulated pressure into the drain, it being observed that at all times the pressure imparted on the device by the operator is in the direction of the drain and opposes the force of the air pressure released thereinto.
Having thus described my invention, what I claim is:
1. In an air pump and accumulator comprising a cylindrical body member having an apertured closure at its upper end and a conical extension at its lower end with a tubular discharge end extending therefrom, and a valve rod positioned centrally of said cylindrical body member and a valve member on the lower end of said valve rod for registry with the conical extension and self-centering in the tubular discharge end, and
pump means for introducing air pressure into a handle being engaged upon said valve rod and movable upwardly with the rod when the other end of the handle is moved toward said tubular discharge end of the device, a spring engaged by the said closure in the other end of said handle, said spring being of suificient stifiness to hold the air pump and accumulator strongly against a clogged drain.
2. An air pump and accumulator comprising a hollow body member formed as an impact extrusion with a conical end having a tubular discharge end extending therebeyond defining a valve seat, the opposite end of said hollow body member having an annular rolled shoulder and a closure disc seated thereon, the outermost end of the hollow body member being clinched over said closure disc, said closure disc having spaced orifices therein, an air pump positioned in the hollow body member through one of said orifices and an apertured nut engaged in said orifice and holding said pump in position, a piston rod of said pump passing through said apertured nut, a valve rod positioned through another orifice in said closure disc, a valve element on the innermost end of said valve rod for selfalignment with the valve seat in the outermost portion of the conical end portion of the body member, a bracket positioned on said closure disc and a handle pivoted to said bracket intermediate its ends, one end of said handle adjustably secured to said valve rod, and spring means of sufiicient stiffness to hold the device securely against a drain biasing the other end of the handle away from the closure disc whereby movement of one portion of the handle toward the closure disc moves the portion thereof engaged upon the valve rod away from said closure disc and the valve element away from the valve seat in the conical end portion.
3. In a drain cleaning air pump and accumulator having a closed cylindrical body provided with an internal air pump and an external pressure gauge for building up a preselected air pressure within said cylindrical body and a release valve for controlling the discharge of the air under pressure from said cylindrical body, the discharge end of said cylindrical body being conical and forming a valve seat, a valve rod extending from said discharge valve and having an end projected from said closed cylindrical body, a lever pivoted intermediate its ends on said cylindrical body, one end of said lever connected to said valve rod and spring means between said cylindrical body and the other end of said lever normally urging said rod and said discharge valve into said conical end of said cylindrical body, said spring means being of sufficient stiffness to forcibly seat the device securely against a drain whereby movement of the spring loaded end of said lever toward said cylindrical body imparts outward movement to said valve rod and said discharge valve with respect to the conical end of said cylindrical body.
