UNITED sTATEsl PATENT OFFICE.

ARTHUR THOMPSON, OF 'BROOKLINE MASSACHUSETTS.

VACUUM- To all whom t may concern:

Be it knownithat I, ARTHUR Tiioiiisoi, of Brookline, in the county of Norfolk and State of Massachusetts, a citizen. of the United States, have invented a new and` useful Improvement iii Vacuum-Cleaners,

of which the followingv is a specification.

The purpose of my invention is to increase the usefulness of the cleaner by giving its nozzle a greater range of-,adjustment yso.v that it may be readily usefully used upon:comparatively thin carpets and also upon carpets having -a thick pile; also, to

Pi/Vide means whereby .threads and other like matters maybedislodged from the floor so that they maybe readily attracted by the air blast and drawn into the dirt receptacle.

Theconstructionof my cleaner also provides a ready means fory connecting the eX- haustfwith a secondary nozzle-of some chari acter whereby the cleaner may be used upon furniture or other `articles than the carpet orfloor. f f l n My invention will be understood `by reference to the drawings in whichit is shown in its preferred and simplest form.

Figure 1 is a side elevation of a cleanerembodying my invention, tlie nozzle,

thread-lifting device and rod being shown in a section-taken on line l-gfl of Fig. 4.

Fig. 2 isv a detail showing .thelieight-adjust- 'ing mechanism in section on line 2-2 of' Fig. 3. 'Fig'. 3 is a view toillustrate particulaijly the under side of the nozzle, the thread-lifter being in placeTand Figliis a longitudinal section of the nozzleshowing the meansv of attachment. of the thread-` are all of ordinary construction and needA not`v be further explained except that the conduit SB has anopeningl'i over which lies.

a .pivoted cover B1. which is adaptedto be swung up out of tlieway to allow a hose 4coupling to be passed in through the open- -f'ing b to the fan chamber within the casing A1, thuscutting' out the licor nozzle` and .CLEANER v specification of Letters rt-ent." Patnted Apr, 25, 1916 Application filed J une 4, 191.5. Serial No. 32,182.

cansing the -fan to draw `through the couj .pling and hose. This is useful when it is de* siredto connect the fan chamberwith any 'other form of nozzle than that shown. This construction allows the Hoor nozzle C to be made integral with the casing A, A1.

A1 is a yoke piece attached to each side -I of the casing A, A1, having pivotally mounted thereon a wheel A4. These parts being also common to the art are not shown in detaih They form a unitary structure whicliismounted to swing with relation to the aXisof the supporting wheels. For this purpose. this (structure has brackets C2 integral with. the nozzle C, and .in Ithese brackets is-carried a rod C1 on each end of which is mounted an arm D, D1 and each one of these arms D, D1 carries a stud .upon

which is mounted a, wheel i to turn thereon so that the device as a whole is supported on theiloor by the three wheels A, (l, d.v

The casing is thus mounted eccentric to the wheelsd, the rod C1, arms D, D1 forming a wheel frame carrying the wheels d, d. The height` of the nozzle C rfrom the ioor depends upon the angle of the arms D, D1 f with' the floor. As shown in Fig. 2, the

nozzle is quite cl'ose to the floor, but-by turnqg ing and locking these arms so that they are more nearly horizontal than as shown in Fig. '2 it'will be seen that the nozzle C will be'lifted with relation tothe axles of the wheels. To accomplish this lifting I have provided at one end of the device a handle (Z1 which is attached to and forms part of the arm D, andl fast upon the rod C1 I have provided one member (Z2 of a lock, the other member comprising a pin J3' sliding in a recess or passage in a portion of the casing A1, this passage being lettered d* .and coni taining also a spring d5, the front end of which bears against said pin da and the rear end of which engages a shoulder d6 in the passage.l The purpose of the spring Z5 is tokeep the'pin Z3 in its forward. position. The lock member d? is segnieilitalfin character and is provided with "recesses d1 adapted to receive and engage the end of tliepin d3. This mechanism is such that upon moving thev handle al1 in either direc- .tiorthe arm D" and rod C1 vto which-,it is pinned is turned either to depress or raise the arm D, andas the arm D1 is pinned to the rod C1 parallel with the arm D the y turningof the rod C1., raises or lowers the arm D1 at the further end of the machine as welhaiid as Athese twoA arms carry the Wheels (Z, the position of the rod C1 and nozzle C with relation to the axles of the Wheels is thus changed and the nozzle C raised or lowered.

lVithin the nozzle C is located a threadlifter E. rI`his thread-lifter comprises preferably a. wooden bar to the under surface of which felt or other textile material is applied. In practice I prefer to use a series of pieces of felt e or the like preferably set at an angle as shown so that alternate pieces will be parallel With each other. For best results these pieces oi felt project slightly beyond the plane of the lower face of the nozzle, and the thread-lifter E is yieldingly supported in the nozzle, the felt pieces c as the nozzle is moved over the Carpet, engaging the threads and the like to loosen them 'from the carpet so that they are lifted by the exhaust and drawn up into and through the nozzle. They with-the dust, etc., passingr through the fan1 are carried into the pipe F to the end F1 of which the usual dust bag (not shown) is attached.

I prefer to support the thread lifter in the nozzle in the following manner: The thread-lifter is provided with openings e1 at each end, these openings being located with reference to the screw pins e2 so that the pins serve as guides to the vertical movement of the thread-lifter. Springcatches e3 are attached to the interior of the nozzle. These spring catches are in the nature of loops having a contracted opening as at e* and the thread-lifter E has at each end a link e made of Wire or the like Wl ich, when the litter is pushed into place, snaps by the portion c* of the spring catch,v so that the lifter E hangs normally upon this portion c.

In order to keep the thread-lifter in proper relation to the opening in the nozzle, I provide leat1 springs e attached at one end to the tln'eadliftei', the free ends of these springs bearing against the shoulder el within the nozzle. Thus the lifter may be easily withdrawn from the nozzle if it is not desired to use it, and may be as easily replaced and When replaced will serve its purpose projecting preferably slightly beyond the opening to the nozzle so that it will engage the surface of the carpet.

To operate this cleaner I have provided a bail G of ordinary torni which is mountedv to swing on the rod C1, one arm of the bail being at each end of the rod Cl, and in addition I may provide means for adjusting the angle of the handle with relation to the `floor. such as a. segment G1 attached to one oi the brackets C and a slotted, threaded pin y, the .slot in which fits over the segment (il (s ec Fig. 2), the outer end of the pin g carrylng a thumb nut, the Whole forming a clamp by which the pin and the segment may be bound together. Theend of the bail G carries a socket piece Gr2 to receive the end ot' a handle, a set screw Gr3 being provided to hold the handle in place. This matter I have not illustrated fully, nor is it necessary to describe it further as it is common in all machines of this class.

I do not mean to limit myself to the precise construction shown as other means of adjusting and locking the height of the nozzle from the floor may be adopted which Will be within the scope of my invention. Moreover, the thread-lifter may be otherwise constructed and supported and yet be Within the scope of my invention.
