VACUUM DUST-nanowar..

To all whom 'it may concern:

Be it known that' we, CHARLES B. FOSTER and lViLMoT lV. GLIDDEN, citizens of the United States, residingat Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Vacuum Dust-Removers, of which the following is a. full, clem-,and exact deoperator, regardless of thc angular position of the handle with respect to the nozzle, and thereby maintain the dust inlet in the proper relation with the object to be cleaned.

Another objectis to simplify the construction of devices of this type, and to avoid the necessity of providing packings and. the like vto' prevent leakage between the movable members of the nozzle.

Other objects and advantages will appear in the course of this specification and the essential features will be more particularly pointed out in the claims.

The invention is clearly illustrated in drawings furnished herewith in which- Figure l is a perspective view of a cleaner embodying our invention. Fig. 2 is an un`y der plan view. Fig. 3 is a side view with thc handle portion broken away. Fig. 4 is a cross section taken through the nozzle.- Fig. 5 is a perspective view of a fragment of a hood. Fig. (i is a vertical section taken on t-he line (3&6 Fig. 3. Fig. 7 is a plan view of a fragmentof the foot. Fig. 8 is a cross section on the line 8-8 Fig. 2. Fig. 9 is a plan view of a slightly modified form of the device, with n portion of the handle broken away. l0 is a sideview thereof. Fig. l1 is a central vertical section of said modiedform, anzi lig. 12 is a side-view of one of the members of the nozzle portion.

Referring first to Figs.- 1 to 8 inclusive of the drawings, A, represents-a handle that is arranged to be connected to a hose 10, which -leads to a suitable vacuum apparatus for Specication of Letters Patent.

producing the necessarysuction. The handle, A, is in the form of a tube and has secured upn its lower end a nozzle B, which is moved back and forth along the carpet or rug in' the usual manner in cleaning the same. The nozzle is preferably constructed of two members 202l, the me1nberf20,' being tubular in form and fitting within the open lower face of the member 21. The member 20, acts as a pressure foot and contains a dust inlet upon its loweiyface, which dustinlet is in the form of a series of perforations 29., extending longitudinally of the pressure foot, and through which the dust 'enters the nozzle tened to present a flat pressure tace for con-- tact with the object to be cleaned. The upper side of the wall of the foot 20, is slotted longitudinally as shown at 23, thus forming a direct passage way throughthe foot 20, andI extending through the ent-ire length thereof. Shoes .24, are provided upon the ends of the foot Q0, which "shoes practically form continuations of the fiatlower face, the objectbeing to give to vthe nozzle a large base or bearing surfaceupon the carpet, so that pressureupon the nozzle from above will always tend to hold the lperforated pressure face in close contact with the carpet.

rIhe hood Q1, incloses the slot in the upper side of the foot 20, and contains two bearing faces 25 that ht snugly upon the eX- terior walls of the foot 20. The hood `and foot portions are pivotally connected together, as by lugs 2(1,wl1ich'project out from the end walls 27, of the foot portion, and ears Q8, that are secured to the hood. i 'As shown, the ears '28 are in the form of plates, that are screwed to the end walls 29, of the hood. The pivot connection is provided merely to loosely connect the two parts together. As soon as suction is applied, the foot portion is drawn into firm contact `with the bearing faces Q5, of the hood, and the pivot;- connections tenjiporarily lose their usefulness. A nipple 30 extends outV from the hood 2l A, forming the connection between the handle and nozzle.

In the modified form, illustrated in Figs. 9 to l2 inclusive, A represents7 the tubular handle and B theinezzle, the pressure foot of which is rotatably mounted with respect to said handle. The nozzle contains two

members

20, 21|', the' member 21'., secured upon the handle A', hyp/,means cfa and this lower side is Hab being lil) nipple 21a, and rotatably connected to the member 530 by means. of a hood 2lb thatl partially encircles the member 20. Said member; 20 acts as the pressure toot and contains inlet perforations 322 through which the dust enters, andan outlet opening 23 provided which registers with the openmg inthe nipple 21, thereby affording a direct assageway through the nozzle to the han le. The member 21, contains a segmental bearing tace upon its lower side upon 'which the pressure foot is seated, and

-said member 2l', is held against longitudinal movement upon.t`ne pressure foot by suitable means here shown as pins or screws 21C. that pass through slots Qld formed in. the hood 2l". The hood 2lb, has a segmental bearing tace, somewhat more than a semicylinder in extent, and the nozzle member 201, is cylindrical and lits in the concave face of the hood 2lb. rllhe cylindrical wall of the nozzle member 201, is iattened on its lower side to form the face which bears upon the object to be cleaned, and also to facilitate the removal or replacement ot' the member E201, on the hood without the removal. of the shoes Q41. This is accomplished by unscrewing the screws 200, and turning the member 201, until its flat side comes in front of either edge. of the hood, Awhereupon the member 201, may be removed laterally through the gap in the hood Bearing shoes 24S, are secured upon the pressure i'oot, 20 to provide means for preventing the tilting of the pressure foot, which would otherwise be occasioned on account ot the shifting ot the handl in the use of the device upon the object to be cleaned.

ln operating the cleaner, suction is applied to the hose l0, and the cleaner is moved back and forth across the carpet, rug or other lilre object to be cleaned, the flat bearing tace of the toot being held in close conln moving the nozzle.

tact with the carpet. bach and forth, the hood is caused to` roclr or turn upon the foot portion, by reason of the .'act that the angular position of the handle is constantly chan ing with respect to pressure toot ando en the handle is swung down quite close to the floor, as for instance when the nozzle is pushed under some article ot furniture. ln order that the best results may be had, the flat bearing face should be held in hrm Contact with the object that is being cleaned, inasmuch as the suction then causes air nap of the carpet from both sides ot the periorations before passing into the foot. 4ln this rn anner a more thorough cleaning of the object can be had because all of the suction force is utilized and practically none is lost. Furthermore, the nozzle is under control oft the operator and the pressure upon the carpet can be maintained at his will. 'We are-thus enabled not only to remove the surto pass throng the i i l evt/,eso

tace dust but practically all of the dust that has lodged in the body ot the carpet, This is practically impossible whore the nozzle travels lightly over the surface of the carpet or part or" the slot is uncovered so that the air will rush directly into the nozzle withhout irst passing through the nap or body of the article to be cleaned. lt will be perfectly obvious that the pressure which the operator exerts in operating the cleaner will ,at all times maintain the toot in an upright position upon the carpet, and that no particular care need be taken by the operator to do this as the'tlat bearing tace will practically prevent the tilting or rocking of the toot.

We realize that various alterations and modifications of the device are possible without departing from the spiritof our invention, and we do not therefore desire to limit ourselves to' the exact construction shown and described except as particularly pointed out in the claims appended hereto.

We claim as new and desire to secure Letters Patent l.
