SUCTION CLEANING: DEVICE.

erence.

To all whom it may concern.

Be it known that 1, WILLIAM V. ORR, a citizen of the United States, residing at fCleveland, in the county of Guyahoga and State of Ohio, have invented a certain new.

Suction Cleanand useful Improvement; in

full,

ing Devices, of which the following is a clear, and exact description, reference beto the accompanying drawings.

inghad invention relates to suction cleaners This . or" the tpye comprising a suction device conappear tained in a movable casing and provided with a collecting nozzle adapted to be moved around the floor or floor covering and collect the dust and litter-therefrom.

l The objects of the invention are the provision of new and improved arrangements for attaching an extension hose thereto whereby, an extension tool can be used upon walls, hangings, furniture, and the like; the provision of new and improved means whereby the attachment; of the extension hose shall .cut off the main collecting nozzle; the provision of new and improved means for retaining the hose connection in place; while further objects and advantages will as the descriptionproceeds. Generally speaking my invention may be defined as consisting of the combinations and constructions recited in the claims annexed hereto and illustrated, in one embodiment, in the drawings accompanying and forming a part of this application wherein: Figure 1 is a perspective view of a suetion cleaner havinglan extension hose secured thereto according to my invention; Fig. 2 is a vertical longitudinal central section through a part of the nozzle adjacent to its junction with the fan casing, showing the hose connection in operative position; Fig. 3 is a perspective view of the hose connection removed from the cleaner; Fig. i is a top plan view of a portion ofthe nozzle and fanicasing, the cover plate being removed Fig. 5 is a view similar to Fig. 2 showing a modified form ofsecuring device for the hose attachment; and Fig. 6 isa per 'spective View of the cover plate which is employed when the hose connection is absent.- V

Describing the parts by reference characters, 1 represents the fan casing of a port able suction cleaner, 2 the motor casing axially secured. thereto, and 3 the collecting nozzle which projects obliquely forwardly from the end of the fan casing opposite the motor,

' said nozzle increasing in width as it departs from said'fan casing and being formed at its extremity'with' an elongated inlet mouth,

transversely arranged, whose plane is substantially parallel to the axis of the fan chamber 1. Said nozzle is supported by means of suitable-rollers 6-6 'for movement about the floor in the usual manner by means of thhandle'7, and the dust and dirt collected is received in a suitable bag 8 secured to an outlet neck 9 projecting from the periphery of the fan chamber.

The interior of the nozzle 3 is formed with one or more passageways establishing communication between the inlet mouth' and I the opening 12 in the end wall of the fan chamber. The upper and lower walls of said nozzle consist of generally flat triangular plates, 13 and 14 respectively, the former being provided adjacent to the .wall of the fan chamber with an aperture 15, normally closed'by means of a fiat'cover plate 16. The part of said aperture nearest to the inlet mouth is curved or semi-circular as shown in Fig. 4, while the other part of the aperture merges with an, elongated slit 17 formed immediately adjacent to and parallel with the fiat end-wall of the fan chamber and also in alinernent with vertical ways 18 formed inside of the nozzle at each side of the aperture 12.

The hose 'connection consists of a fiat metal plate 20 adapted to be inserted edgeiwise intothe slot 17 and along the ways 18 so as to cover the aperture 12, there being a hose nipple 21 projecting obliquely from the forward face of the plate and adapted to be receivedby the aperture 15 when the plate is fully seated. A flexible extension hose is secured to this nipple in any suit- The aperture 15 is preferablyof such a size as to allow the nipple to extend freely therethrough, thus facilitating manipulation.

In the construction illustrated in Figs' 1 to 4- inclusive 1 have shown the upper and lower walls of the nozzle as connected by a wall 24 forming an oval symmetrical deflector extending along the longitudinal axis 1 of the nozzle from a point adjacent the inlet 1T1011i3l1 to a point adjacent the opening 12. In the present embodiment this wall 24 defines a, recess or cavity which is open upon the bottom of the nozzle but whose The wall 24:

cooperates with the sides of the nozzle to form two separated passage-Ways leading from the suction slot to the opening 12. Projecting through the Web 23 upon the center line of the'machine, I have showna longitudinally slidable bolt 25 normally held yieldingly in forward position by means of the spiral spring 26. I. have shown this bolt as provided intermediate its ends with a rigid thumb-pin 29 which projects through the slot 30 in the top Wall of said recess and also serves as an abutment for the spring 26. The forward end of the bolt 25 is formedfor engagement with the boss 31 formed at the lower side of the hose nipple, so that upon the insertion of the plate this bolt will first be pressed back and afterward automatically lock the con nection in place. Disengagement of the .same is readily effected by moving the pin 29.

'In Fig. 5 I have illustrated a slightly modified construction of hose attachment, wherein the top and bottom walls 13 and 14 of the nozzle are unobstructed; Tn this embodiment I have shown the nipple 21 as provided With-a rigid radial boss 32, apertured for the reception of a rotatable screw 33 adapted'to enter a threaded aperture 34 formed in the wall 13 adjacent to the opening 15 The cover plateld, employed when the hose connection is removed and the machine is being used in the usual manner, is pref erably of substantially semi-circular shape as shown inFig, 6, and is secured in place in any suitable manner, preferably by means of a spring clip 35 secured to its underside. A rib 36'is preferably provided for insertion in the slot 1-7 tofix the position of this plate.

While I have described the present embodiments in detail, I do not confine myself to such embodiments or limit myself to such details except as the same may be positively recited in the claims hereto annexed or may be rendered necessary by the'prior state of the art.

Having thus described my invention,'
