Application filed June 9, 1911 Patented Feb. 6,1912. Serial No. 632.220.
To all whom it may concern:
llr it known that l, .hamwxm-zu lllACKEN- mi: Java, :1 subject of the King of Great Britain and Ireland, residing; at Shetlield, in the county of York, llngland, have invented improvements in Portable Air \\"itlulrawing or Vaeuuni-Producing Apparatus, of which the following is a specification.
This invention haa reference to air withdrawing or vacuum producing, apparatus suitable for use. in that kind of portable raemnn cleaning apparatus for removing dust from carpets and other articles, wherein the neeessaiw' vacuum is produced by bellows. Such vacuum cleaning apparatus as heretofore. constructed with bellows or other air withdrawing devices operated by pedals or bv hand, has, when being used by one person only, a small range of action so that the bellow: or equivalent portion of the apparatus has to be frequently moved from plat-e. to plaee, as the cleaning: proceeds, net'essituting frequentinterruptum in the cleaning operation and in\"ol\'ing liability of damage to furniture. 'lhese. dirii'dralr tages (-an only be avoided or minimized by employing two persons to work the. apparatus, one to operate the bellows or equivalent and the other to apply the suction nozzle or equivalent device to the carpet or other artiele to be clean d, in which casea suitably long length of suetion pipe is HOCEHstll') to secure the tlt'sll't'tl range of action without frequent shilling of the bellows or equiva lent Stu-h apparatus is therefore not adapted to be operated in an easy and conrenient manner with the minimum of labor and M: llh to enable the desired cleaning, by r llttlon to he etl'eeted in a rapid manner.
Now the prext'nt invention has for object to pro ide improved air withdrawing or vacuum produt-ing apparatus specially adapted for use in vacuum cleaningapparatus ot' the kind referred to, whereby sut'h apparatus can be easily and conveniently used in a continuous manner by a single person and have an unlimited range. of action with a coinpa .-at'1\'el short length of flexible suction tubing.
For this purpose the invention consists in the novel construction of bello'ws, constituting portable air withdrawing or vacuum producing apparatus, and m the combinations and arrangomenta of parts all a here inat't'er more partieularl described and pointed out in the-claim.
In the accomtmnying drawings Figure 1 shows vacuum cleaning apparatus of the kind referred to embodying bellows (ul|- structed according to the present invention, the said figure showing the manner of using such bellows. Figs. 2 and 3 show reaper tirely in central vertical section and plan and to a larger scale than Fig. 1 one of the bellows used in such apparatus.
Air withdrawing means to constitute the exhausting portion of vaeuum (leaning upparatus comprises, arr-outing to the. present inventio au shown in Fig. 1, two entirely separate and independent bellows A and ll adapted to be attached to the feet of the person using the apparatus and movable there,- with frdm' place to ilaee and to be worked continuously by slltll'ptlhttll raising" and depressing earl] leg: alternately, either while remaining; in the aame position, or by and while walking about the room or other place in which the apparatus is being used, the opening movement of (llt'll bellows, to produce the suction or air exhausting action, being etl'eelt-d l muor :utuc springs arranged within the bellows and the closing of the bellows, to discharge. the air drawn into the llt'lluh's on the suction stroke, being ell'eeted by bringing the weight of the operator to bear upon the. top of the bellows.
In the example shown each bellows (:omprises top and bottom boards a and 1/ respeetirel that may he of the shape shown, or of other suitable shape, and are eunneeted together by impervious tlexihle material a, such for example as leather arranged to allow of the top board being moved toward and from the bottom board to form a bellows within which a spring device such as a coiled spring (I, preferably of the double \Ollll'C shape shown, is arranged to raise the top board, when relieved of pressure, and cause an exhausting aetion. The spring, which may be varied in strength to suit the operators weight, can be held in place in any convenient way, as for example by projections e that enter the ends of the spring and are formed on blocks f fi xed to the top and bottom boards. The sprmg and bottom block f are inserted apparatus to work in ii. with an air suction through a hole formed in the bottom board I) and normally closed in an air tight manner by :i plate (1.
The bellows is provided with an air inlet valve i. normally held against its :tlli by a spring j, and with an air deliver port and valve l.'. The top is hinged .Iirewtlv to the bottom board I. the air inlet It and suction valve 2' heiu; rar ied by the top board. The top board a is provided with convenient means. such for example as rlips, or straps, or both, by hi-ch it can Ir;- t-a il v and conveniently serum-l to the operators boot in such a manner as will permit of its being very quickly attached thereto and detached therefrom. 1n the example shown, each top board a is provided with a fixed heel piece in and a movable and adjustable toe piece u ar ranged to slide in guides 0, a strap p serving to lirmly fix a person's boot between the heel and toe pieces after insertion between them.
The means used for securing the bellows to a persons boots is such as to allow of the bellows being worn and moved by the person from place to place as indicated in Fig. 1. Also, both toe and heel pieces should be so shaped as to tit approximately either wide or narrow boots, the toe piece allowing of the use of either long or short boots.
In the case of hand operated bellows or equivalent devices, the muscles of the arm may soon become fatigued owing to their being called upon to perform novel or unusual'duties. In operating bellows according to the present invention however, the muscles of the feet and legs are only called upon to perform work such as they are usually accustomed to. Consequently no novel or unusual muscular movements are involved by the operation which is carried out with a minimum of muscular fatigue. Vith the arrangement of bellows described, the hands of the operator are leftfree to manipulate the suction nozzle or, a combined suction nozzle and air filtering device, constituting part of the vacuum cleaning a )paratus and which, in each case, is suitably connected to the bellows by flexible tubing, suction and delivery valves being rovidcd in suitable positions to enable the the well known way.
In the example shown in Fig. 1, 'r is an air filtering device of any suitable construction and z a suction nozzle. lhe air filtering device, whatever its construction, may conveniently be arranged between and suitably connected to the separate bellows A and B, and the suction nozzle 2 with which latter it may be combined, as shown, so as to form a combined air filtering device and suction nozzle that can be manipulated as one article by a suitable handle. In the example shown in Fig. 1, the upper end of the casing of the air filtering device 1* has a socket 3 to which a handle, formed by an air outlet pipe 3, can be detachably secured so that. the combined air filtering device r and suction nozzle 6 can be readily moved, by either hand, over the floor or other place from which dust is to be removed. The air inlet pipes it of the two bellows are connected to the air outlet pipe 3 by a pair of flexible tubes 5 and a single length of flexible tubing 4. which will allow of free movement of the combined nozzle and air filtering device, do not necessarily drag upon the ground, and will not. hamper the operator. The air filtering device 1' is pro vided with an end cover a that is removably attached to lugs on the said device by hinged levers or handles, one lug and lover being indicated at u and t respectively in Fig. l.
The bellows A, B, flexible tubes 4, 5, handle 3, air filtering device 4' and nozzle 2 are readily detachable one from the other to allow of their being conveniently packed up when not required.
That I claim is 1-- "he combination of a pair of independent bellows adapted to be secured severally to the feet of an operator whereby they may be moved from place to place while being 0 aerated, flexible piping connecting the suction inlets of the bellows, and a suction pipe connected to the said flexible piping at an intermediate point of the length thereof whereby a continuous inflow will be established through the suction ipe.
