- PNEUMATIC CLEANING IMPLEMENT. 1

To all whom. #may concern:

Be it known thatLSEY'MoUR L. GU'rHonN, a citizenof the United States, residing in the city, county, and Stateof New York,`have 5 invented certain new and useful Improvenieiits in Pneumatic Cleaning Implements,

` of which the following is aV full disclosure.A

My invention" relatestotliatclass of pneumatic. cleaning implements' adapted to be 10.

moved over the surface tov be cleaned, and in which a -suction is created means of any suitable lapparatus, in order that dirt .and air may be drawn from the floor or surface being lcleaned, into the implement, .and through suitable pipes or 'con-y cariied away duits.

I The .objects of my invention. areto p'ro;

vide an implement of fewfparts, simple. in construction, cheap-to manufacture, .and so necessary tewerk beneath obstructions such as benches and desks in-school rooms,"and yet'that the operator may rotate the suction head upon the Hoor in Whatever position the handle may be, by twistingthe handle. I 'accomplishA these objects a combination ofparts. y Y M The preferred embodimentfofmy invention is shown in the drawing accompanying and formingapartof this specification. In this-drawing Figure lis aside elevation of a 'cleaning .implement embodying my improvements, the handle beingf'broke'n away. Fig. 2 isasectional view taken on the line 2 2 of-Fig. 1. Fig.' 3 is a transverse sectional View" of the 'struct-ure shown in Fig. 1 takenon theI line 3--3 ofthat figure. 10 :4,- 5 and Gare detail viewsv showing fmodifed suction heads.

.Referring in detail to the structure'shown in Figs. 1,-2 and 3, the numeral' 1 designates the base of the suction' head .which has feltl "45'pads 2 secured .to its lower-surface. AL

threaded ring"3 is mounted'on the Asocket element 4, secured' to the base y1^. The ring land extends up into the vs'phericalhead 6;

55 Pins 10 are secured to the conduit 9 on o'ppo constructed l and arranged that, while the'.

` of the suction head, communicates with' two' site sides and engage. slots 11 formed 'on the specificati@@Lezers-faena Arfarented sepas, 1'9'13. 1 Appiication ined Juiy aaien. fv'seriaindamgs'z.: Y i

inner side of this spherical head 6. 4The combination of parts forming the joint. be-

tween the handle and-the suction head 'is such that the handle ofthe device can be inclined in vany direction with respect tothe .suctionhead' without disturbiig the proper position of the. head on the oor, and by means of the pins' 10' in the slots 1-1 the suc.

tion head is prevented.' from .twistingwith respect to'thehandle but the suction 'head' can be rotated on the door by twisting the handle 7 in whatever position gthe. handle may be'. The members Sand 4 form with the spherical head 5 a ball`and-socket joint' which can' always `be ladjusted or taken apart by .adjusting or removing A--themember 3,

'which has a screw threaded engagement with! the member 4.

The suction .orifice 8 .formed in the bottom suction conduits 12 which open outwardly onl opposite lsides of the suct'10n"head. The

'outer ends or openings of the conduits are substantially as wide as the head is long, and when the head .is moved along the floor all particles of chalk and the like will enter the enlarged openings and be guided by the' inclined walls'16 4of the conduits tothe ori.

tice The oppositelv disposed conduits 17 have their outer ends closed and are in tended to pickup the fine articles of dustwhich pass under the hea along.

as it is moved isisy in shape. and the suction conduits 12 Vextend totwoA opposite corners of the' device. -This shape', and arrangement'of conduits is ad-4 vantageous'in some instances when used with my improved implement,- particularly where it is desired to removedirt and dust from among chairs, furniture and similar articles.

In the construction shown in -F ig. 5 the suction head-is made triangular andthe central suction orifice 8 communicates by 'three sepaof the triangular base. In Fig.l 6 the suction head is o ctagonal inshape, and there are four dust slots or ,suctio'nl conduits 12" tml suction orifice 8, and at their outer ends' iny enlarged openings '13; The relation 4ot' 'which terminate at theirinner ends in a centhe enlarged openings13'" and the sides 14 of the head`is such that as the suction head move'd alon-g the floor,r a particle Will "either enter one ot` the enlargedopenings 13 1n the first instance or else Will strike one of the inclined edges 14 and be forced .along the edge until-it arrives opposite one 'of the enlarged openings 13s, so as to then be .drawnthrough Athe suction or dust conduit 12c into the entrai orifice andreinoved in the usual Wav.

The' 'operation` ot-the devicelwiit rthe suc,

tion head shou'ui in' Figs. 1,'2 and ,br either. of the modifications shown rn Bilge: 1, 5 and who controls the position dtp-the deviceby vmeans of the handle 7, and nioves it ,ver`

' the' floor. The dust. and are Adrawn in through the dust `conduits 1231.12.12, 19;'into the central oriceand then'out-,through'the conduit 9 and the hollowhandle of the'de- Vice. The ball-andi-'soket joint permits the `'operator to incline the"handle"als slhoufnatl) and 2O in Fig. 1, orflin Fig. 3 or in any other inclined position :which may be de Sired. This makes it possible to conveniently 'Witnessesz andf speedily insert the 'device beneath benches` and pieces off furniture, "andirhere-- forefto reach accunntl'ations of dirt wilder such-articles which it would notbe possible to reach with a device having a fixed handle, or having a handle adapted to move only a single plane. NotI only can the device be inserted as above described, but the suction' head may be rotated While the handle is inclined, by nierely twisting the handle.

I do not claim herein the improved arrangement ot suction conduits or slots shown on the lower face of the suction head but Vhave claiined'such matter in my pending application Serial No. 662,27 9.

That l cla-iin is:

`1. The combination in a device of the kind described, of a suction head and a hollow handle connected therewith by a ball-andsocketuniversal joint, substantially as described. 9.. ,The combination, in a device of the ind described, ot' a suction head and a fhandle connected therewith by a'ball-andsocketwniiversal joint, and nieans for preventing said handle troni being rotated about its axis with respect to said..headsubstan' tially asdescribed. 1
