toenai s To al'l 'wkom it my concern Be it known that I, Harmon H;
a citizen of the Un-ited States, and a resident.
ofCanal Dover, countyofi Tuscarawas, and
State of Ohiofhave invented a new anduse.
ful lmprov'emei-it in Pumps for Vacuum;
Qleaneraof which the tollowingis a speci y 7 ficatio-n, the principle 'of the-invention being trons.
herein explained and the best mode in which I'have contemplated applying that lprinci ple, so as to distinguish: itfrom other'inven The .'present;-;invention:' relates to vacuum clea -hers, and more articula'rly wan. type of'cleaners whichare adapted to be operated hand. Variouscleaners of thisv type are. nowyindmore orflless general-use, but I have toned: that the majority ofthesei'are not only extremely inconvenient to operate, but
are-also d-ifficult .to manipulate by'reason' of theconsiderableamount' of power necessary to create the suction. I
"Thepresen t machine is adapted to efiiciently' clean a surface with biit little exer tion on thepart of the-operator, and is so made. that it is extremely convenient, andea'syto handle. It may,,.of course, bemoui fied adapting itto different types of work,
and the cleaning of surfaces such as oors is but one of the many operations which my r machine is intended to perform.:
- andrelated ends, said invention, then, con-' 405 ofjjvarious mechanical forms in which'thehand operated, it is extremely. dilhcult to] 'manipulate the same for any length of side elevation of my' cleaner, showing To the accomplishment of the foregoing sists of the means hereinafter-fully described and particularly pointed out in the claim.
The -annexed drawing and the following description set forth in detail certain mechanismembodying the inventiomsuch disclosed means constituting, however, but one a view similar to Fig. '1, but showing the machine. fully extended at the end of theop erati ve stroke; Fig. 3 is a section on the line 3 in .Fig. 6 Fig. 4 is a section on the line l eiin Fig. 5; Fig. 5 is a section on the line 55 in Fig.3; and Fig. '6 is a view taken-,on the line ,66 in Fig. 2..v
My'machin'e consists of a dustreservoir or inlet chamber'l, as it may beca'lled, which Specification-0t Letters Patent. I. Patented [11y Application new '24, 912. Serial1 \'o."699 ,380.' i

I The cylinder 5 willbe-open at its lower end i adapting-1t to engage the piston and to slide ;over the dust chamber, as shown in Fig. 1; gThe head 6 of. the cylinder will have two valves land an apertured handle 8 attached centrally to; this head and adapted to I 'receive a manipulating handle 9" passing through the aperture and attached at, one '1' end to the-piston. (i. The latter is attached by means of a bayonet connection, shown in Fig."2, tothe dust chamber. This piston leather" or some-other suitable "material 12 which will engage-the cylinder and prevent the passage of air around the-removable headmf r In the dust chamber-there is mounted a wire screen 13 which is cylindrical inform and is adapted to hold extended a cloth bag 14 which will prevent the dust entering the dust chamber with the air 'passing out of the same into the suction mechanism. The
nozzle 2 will have an extension 15 which will extend into the dust chamber andwill tendto prevent the dust fromialling back down into this t-ub'e, afterit has entered this chamber.- y i The important-features of my invention have now been described, and the operation of the same will be taken up.
In machines of this general type, namely time by reason ofthe force necessary to operate the suctionmechanism"at a suiiicientspeed to draw dip .the dust from the surface being cleaned." This is particularly true of mechanism in which the suction means comprise bellows, since a bellows does not begin to operate until it has been expanded for about' onethirdpof its totalcapacity. .This necessitates -an' extremely long stroke',- or else the machine must be operated at a 'veryhigh speed, neither of.
,which is feasible in hand erated Ina-f chines; the first on account of t e inconvenience, and the second on account of the j here shown, there 1s 0 cien'cy. 1n the operation,

'- discharged from it through power required. When the suction; mechanism COIIIPIISGS a pum such'as the one air being drawn in throughout:- the suction stroke.- The pump, however, cannot be made ofvery large diameter, and it is necessary to lengthen the stroke, which means that one of the handles must be separated'from the other by a considerable distance at'the limit of thesuction stroke. Thisis extremely inconvenient and fatiguing to the operator. U'pon an up ward movement of the cylinder a vacuum s produced, the valves 7 in the cylinder belng closed thereby and the valves 10in the piston being opened. Air is thus" drawn into the dust chamber 'throu h the cut off from the length of the machine when extended, and, the operation is made that much more convenient and sim le. By means of the bayonet connection 'etw'een the piston and the dust chamber, it is possible to separate the same instantl when the Wire'screen and the dust retaining bag course no inefiiton member,

The advantages of my'j cleaner are. its simplicity, ease of assembly and itsextremely convenient operation. Other modes of a plying the principle of my invention mag e employedinstead of the one explaine ch ange being made as regards the mechanism herein disclosed, provided the means stated by the following -'claimor the equivalent of such stated, means be employed. a
I therefore. particularly point out and distinctly claim as my inventmnz-g In a devlce of the character described, the
combination of a c lindrical open-ended suction chamber, a cy inder open at one end and adapted to fit snugly over said suctionchamber and to slide thereon; a head adapted to removably engage andcoversuch open end in said suction chamber;'a handleat-g tached to said head, thereby forming a pisi I I said head hav ng an external: circumferential groove and a packlngrlng mounted in such groove, said-cylinder hav-- ing an aperture in its closed end-adapted to; engage said handle, flap valvesrnounted in said head and said cylinder adapted to pro.-
vide, ingress and egress of air from said chamber upon relative reciprocation of said cylinder and said piston; and a second handie attached to the closed end of said cyl inder.
