Application filed June 21, 1.309. Serial Ho. 503.337.

T all-1117mm it concern Be it lgnowvn that We, THEODORE Nicos- DEAN}? and JOSEPH H. Tmrrmx, citizens of the United States, and both residing in the cit and county of Philadelphia, State of Pennsy 'ania, have invented a new and us ful Vacuum Cleaning Apparatus, of which the following is a specification.

This invention relates to vacuum ceasing apparatus and more particularly to the type of portable cleaners adapted for removing dust. dirt and foreign material generally from carpets, upholstery fabrics the lilze by currents of air and in which the pump lug mechanism and its adjuncts are as compac ly arranged and small and light as post. is for eliicient operation.

In vacuum cleaning apparatus as heretofore construct-ed it has been proposed to arrange the entire mechanism Within a single casing in order that the same may be more readilyhunclled and curried from one place to another,.but it has been found in vievv of the variety of uses to which such an apparatus is adaptable that such a construction is notentirely practical for all the intended purposes, since it is frequently undesirable for the air passing through the apparatus to he laden with dust and dirt which has been removed from the carpets, upholstery or the li and therefore the single casing construction becomes open to serious objection.

in our present invention. we provide an apparatus substantiull as compact and transportable as those heretofore devised and wherein the (lust laden :ur drawn i to a. receptacle entirely separate and dis ct from the casing inclosing the operat- V mechanism hutvvl'iich may readily in: n ctetl thereto, thereby assembling the utus into =1 single unit when used for g purposes. l" often very desirable to frequently use the meclmnismfor blowing purposes. such as reuiovingl'particles of dust and dirt from crevices and places inaccessible to -the suction hose or using the air for drying the hair or giving a bed an air hath; lllgl'll or which uses it is of course obvious thut'the blowing 01 dust and dirt from the machine is highly objectionable.

\Yherc the oevxce is operated solely as :1 cleaner and the dust collecting: receptacle is in attached position. it is dwiruhle to have the parts so pos' tioncd as to iuuner divert or conduct l'llv dust laden current air into the said rcccg'itncle or separating apparatus untl the locatu 1 of this receptacle is such that it is iuuxu .l conveniently accessible to; the purpi sol reumvu. inspection or repairs. novel m ans living provided for retaining the dust sa arsti g devices adjacent the apparatus. and suitable locking devices liieingeniploved vvnich (2:11 be readily manipulated so that the several urts of the apparatus can be reudilv connectecl or c requirements.

lt is further c 'ahle that on 'lsiou he made; for euiploraueut of a 5H1 :lJ-le pumping or suction and discharge apparlus in corijunction with :1 motor having :1 direct c nection. the to which not liable to easuv get out of order and which can he convexiiently located so as to be at all times capable of convenient inspection and rc mirs. it necessary, there being tl us turnout adjacent the apparatus :1 vacuum reserroir \alwiein the discharging devices :u'e locutr-d. vvhilc in the casing proper there is a prsssurc r 31\0llcontaining the motor and pumping chamber or pump proper. the h: 'ter lflt'z'lllll in the present instaucrulmve the said motor.

To the above ends we have devised :1 novel and simple construction of pumping uppura which is located iutcrumliutc oi the umand its adjuncts and the dust scpnratiog deviccs, whereby the power is applied rectly to the suction creating devices out our loss of energy. and provision is turther mode for enabling any part of the suction or discharge apparatus of equivah devices colic rczulilv acccssihle at all tinus low as possible. 'lltl'llly provision made to:- arranging the PIHUPIUQ apparatu chamber 11: one or mutumiug rho tor and pressure while the vacuum reservoir dust cleaning or scpululn= :l'

:onuectcrl in accordaurr with illll lllfi laden air current is contained in with.

moving .the dust and dirt from the dust a compact receptacle adjacent the a foresaid'casing and adapted for detachable connection there- It further consists of other novel features of construction, all as will be hereinafter fully set forth. v For the purpose of illustrating our invention we have shown in the accompanying drawing one form thereof which is at present preferred by us. sin e the same has been found in practice to give satisfactory and reliable. results. although it is to be understood that the various instrumentalities of which our invention consists can be val-i ously arranged and organized and that our invention is not limited to the precise'arrangement and organization of these'instrumentahtles as hcrem shown and described.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the. drawings:l designates our novel construction of vacuum cleaning apparatus, the same consisting of a casing 2' containing the operating mechanism, and a receptacle 3 for the dust separating devices. The l ormer casing 2 comprises a base portion 5 and an upwardly extending flange (l, the latter being provided with a shoulder 7 upon which rests the outer wallor casing 2, which in the present instance is preferably round or cylindrical, although it will be apparent that the exterior shap" or contour ol. the apparatus may be changed or varied, according to requirements.

Fig. 5 represents a see the pumping apparatus In order to permit removal of the baseA from the casing 2, a number of plates 8 are fixedly secured to the casing at suitable intcrvals in any well known manner, each of said plates having a screw threaded end 9 11 designates a plate secured to the casing 2 and having an opening 12 therein sopositioned as to aline with an opening 13 of the casing 2, which latter serves as an inlet port to the interior of said casing and a source of connnunication between the recep tacle 3 and the casing 2. The plate '11 is provided with angular extensions 14 forming a dove-tailed recess with which a suitably shaped plate 15, secured to the receptacle 3,

cooperates, it being understood that an aper-- g5 ture or port 15 is'formed in this latter plate, communicating with they interior of' the receptacle 3.

It will be noted that a packing ring or bushing 13 is located in the opening 13 and preferably projects therefrom sufli-' ciently to contact with 'the plate 15 and thus insure a tight joint and prevent leakage when the parts are in assembled position.

16 designates a top suitably secured to the casing 2 and having an opening 17 ther through, forming an outlet port' or dischargev for the air, which passes through and in the present instance this opening 17-has a suitable union 18 mounted therein, whereby attaching devices may be connected, as desired.

19 designates a handle secured to the top 16, said handle being preferably of sufficient lengthsofliat when it is'desired to transport the apparatus from one apartment or .room to another it can be readily grasped by two people, if necessary.

The receptacle 3,. which:- we term the acuum chamber or reservoir, is providedwith an outlet 20 a'lined with respect to the openings 13 and 1f) and servingto permit the air passing therethroiigh to exit to the pumping chamber. As herein disclosed, 21 designates a ring flange fixedly mounted in' any well known manner and adjacent the top of the receptacle 3 and serving as a securing "'ineans for a protecting screen 22 formed of wire mesh or gauze or the like, ,and vwithin which is removably secured a dust. bag 23. In the present instance this dust bag is provided with a bottom '24 of wood or othersuitable material and has its rovided-with a looped portion 24* surrouncmg a ring 25 of a fl l ameter substantial-ly tha tof' the interimof upper end open and the receptacle 3, wherebywvhen the same is placed within the'rcce tacle it will rest uponthe flange .21 and bolt the dust bag incol rect operative position. 1 i

To this huh 53 is secured a flap valre 5;. here shown as comprising a plurality of sectims,

Cr (D vsition shown in 1 Fig. 7), while npan an opposite movement of the diaphragm the arms 01 the spider L9 will prevent movement of the valve M in the reverse directions. the position being that indicated in Fig. 6.

I? designates a. partition preferably formed integral with the section &2 and liil)\lllk(l with a l ilurality of openings 58 therein forming: a spider-like construction; th arms of which emanate trom a hub 59, which lait -r forms with the screw 60 a se-' curing; means for a valve 1 of similar 00nstrurtion to the ralve'fil already described.

lt will he noted that the inlet passage 41 for the dust laden air discharges on the 0pposiie side of the valve 61 from the dia- -phraem if and theretnre to separate the suction from the exhaust a top 62 is pro vided and secured by means of a screw or the like to the hub 59. ivhile the outer edge or thesaid top contacts with an annular packing: ring: H ha ring: a portion suitably 10- rated in a recess 65 prorided in the Wall of the section and it will therefore be. apparent that when the screw (33 is firmly secured to the huh .15) the top 62 will conipress the parkin; 4 and prevent escape at air to the pressure reservoir.

W dcsienalcs arms \rhirh are s ruzwd. t0 the ring or spider se ured lo the d e, phra nz I the said a ms lwing fastened rods 6 139 which latter terminate in the eccentric 70, it being noted that said eccentric. strap and connecting, rod 9 and head 68 are preferably jointless or made integral or in one piece i 71 designates an. eccentric by means of which the eccentric strap and connecting rod are actuated,' isu itahle bearings being located therebetwee'n, for the usual purpose. In the present instance we preferably employ a motor 72 of thc' ele ztric driven type, since the same capable of being readily coupled to electric light fixtures of usual, construction.

It will of course be understood that we employ two eccentric straps connecting rods and their adjuncts, as will befappwrent from Fig. although it is evident that a single eccentric strap and connecting rod might be employed, if desired. It will also be apparent that we have a direct connection from each eccentric to the diaphragm 49.

it will be clear from the description above given that between the diaphragm l9 and the partition member 5,? is formed a somewhat enlarged pumping chamber 73, such chamber extending nearly across the casing of the apparatus, while/the proportions of this chamber with respect to the area of the adjacent pressure chamber 74-. as well as to other correlated parts is such that there will always be a substantially uniform quantityflof air forced" into'the pressure reservoir 7+ and discharged from the outlet port 17 so that the speed of the motor will be at all times substantially uniform, irrespective of whether the nozzle 37 is placed against the carpet, upholstery or the fabric to be cleaned. or whether it is Withdrawn therefrom and the motor is simply running free. so that thepumping apparatus is simply sucking in air at atmospheric pressure.

In Figs. 2. 7 and we have shownthe preferred manner of enabling the operator to readily connect the apparatus up with an electric light socket, 75 designating the plug for attachn'ient to a socket of ordinary construction, whereby when the same is connected to the usual electric light fixture and the current is conducted through the flexible connection 76, the motor may be started.

It willbe noted that we have preferably arrang d a cut out-switch 77 see Figs. 7 and S at a convenient point on the apparatus in order that the same may be con-v trolled directly at the machine in case ofa long connection 76 or other reasons.

rr en-t oi 'omf invention wherein the vacuum reservoir 3 may be positioned directly on top of the casing 2. in which case it will of course be understood that suitable changes inv construction are necessary for.

proper operation. As here shown, these in Figs. 9 and 10 we disclose an emhodi-'- changes consist of forming the outlet 20 in the bqlttom of the. vacuum reservoir 3, to which latter the plate 15 -is attached and the plate 11 fixedly mounted on the top of the casing 2,.it of course being seen that the openings 13 and 12-are properly alined to form the air passage. In connection with this arrangement a suitable apertured cap 78 is employed to $01111 a retaining box or the like for the packing 13*. The outlet -'opening 17 or exhaust is here shown located in the side of the casing 2.

It will be apparent that the angular extensions l-t form a dove-tailed connecting means between the two plates and permit the two receptacles being detachably secured together ina firm and substantial manner and practically sealed by the packing .employed. .The operation is as follows :In operating the device the vacuum reservoir 3 is first attached to the pump casing 2 by inserting, the plate 15 within the extensions l-l and then sliding the two plates together so as to bring the apertures into alinement to permit the passage of air from one to the other. Assoon as the fitting 75 is pl'aced in connectionni ith a suitable socket and theswitch 77 clnsed the current is admitted to the motor. the parts then appearing as seen in Figs. 2 and according whether the vacuum receptacle 3 is at the side or on top of the casing 5 In Figs. 5 andG the diaphragm 49" and its adjuncts are seen in the positions they may assume upon the rotation of the eccentrics 71 and it will be evident that the diflerent positions'ot' the parts will rapidly in succession assume the appearance seen in these figures, it being apparent that as the connecting rod (39 moves upwardly they will raise the diaphragm--19 into/the position seen in Fig. 5, whereuponthc air in the chamber 73 will be compressed and will cause the several diaphragms to assume the positions there indicated whercupon the air will pass in the direction of the arrows as seen in F 5, downwardly into the presf sure chamber 74 and thence to the opening 17of the atmosphere. A further rotatioir'ot the eccentrics 71 will cause the descent of the connecting rods 69, whereupon the dia-- the accumulation 0t resu e-inure"pres:

sure chamber 7- as willbe apparent to those skilled in the art.

' \Ve have found in practice that the most satisfactory results are obtained from the employment of a motor actuating two cranks or eccentrics, each having a connecting rod connected at one end to or actuated by one eccentric, while the opposite end of merated as desirable in the statement of the invention and the above description and while we have in the present instanceshown and described the preferred embodiment thereof which has been found in practice to give'satisfactory and reliable results, it
