, cross-head cleaning tool on the floor end of the legs of the support,

thereof.

Because ,oithe swiveled' connection between theii'loor tool and the suction tube or suction handle of the cleaner, it is evident that cleanersot this type may be read ly employed tor sweeping beneath furniture or the like, by merely swinging the device about the atria oi the cleaner handle, as fully set.

forth in my Reissue Patent no. 16,224. According to the present invention, I have provided an adjustable support hingedly and rotatably connected to a portion of the ri id frame of the cleaner, whereby when the an and motor casing and other portions of the frame of the cleaner are swiveled about the floor tool, the adjustable support by reason oi its swiveled and hinged connection to the frame cooperates with the floor tool to support the cleaner in its various positions.

The object, therefore, of the present invention is to provide greater versatility in such roller supports, to materially strengthen, and to simplify the adjustment of such supports.

To these ends the invention consists of the design, the arrangement and construction of parts as herein specified, and illustrated inthe accompany drawings, in which:

Fig. l is a side elevation of the suction producing means, suction tube and cross-head floor tool, of a bag type air-way cleaner having the present invention attached, and suggesting the hinge adjustment thereof in dotted lines;

Fig. 7 shows a cross section of one of the the legs are to be curved strips preferably used in the construction of the legs and cross-brace of the device;

Fig. 8 shows a bag type air-way cleaner in the ordinary working position with the present invention in place, lines how the support is designed to hold the cleaner in an erect position when working attachments are connected to the cleaner handle;

Fig. 9 shows the tank or caddy-form airway cleaner in the ordinary working position, with the present improvement in place;

Fig. 10 shows the bag type air-way cleaner, with the present improved support in the swiveled-over position, as occurs in cleaning under furniture with the swiveled cross-head or air-way cleaning tool; and

Fig. 11 shows the operation as last set forth, when connected to the tank or caddytorm' air-way cleaner.

Similar characters of relerence denote like and corresponding parts throughout the several views.

Referring to the drawings, 1 designates a suction tube, 2 a tan case, 3 an electric motor, as they are combined to form the suction producing means in the construction of an air-way cleaner to which this roller support is attachable. A projecting plate or lug t extends from either the motor casing or the fan case so as to have pivoted to it the ele ment 4, the said element being provided with a pair of lugs 7, 7 and with radial furrows 5', 5, etc., which are to engage radial frets 5, 5 of the lug or bracket 4, any two of them coinciding, or snapping in, according as the some is turned on its pivot.

The lugs 7', 7 are designed to have pivoted to them lugs 8, 8 of the legs 14 of the device.

and suggests in dottedwhen the same are to be held'in the upright position as shown in Fig. 1.

The legs 14 are further framed together by means of the bow-shaped brace 15 connect- 5 ed at 17, 17, at which points the rollers 16 16 are attached. The frame thus assemble is adapted to swing on its hinge 9, 9 so as to take the position shown in full lines in Figs. 1,

8, 9, 10 and 11. When adjusted to this pos 10 tion, as shown in dotted lines, a detent 18 1s ada ted to engage with the brace so as to hol them in the position desired. This detent is secured to the motor case or fan casing at a suitable point, as 19.

By making the legs 14, 14 andthe brace 15 of a semi-circular cross section, as shown in Fi 7, they are materially stifiened and fit togetEer so as to make a secure joint when the rivet and spindle 17 securing the wheel 16 is put into lace.

An assemb mg bolt 12 is passed through the center holes which coincide when the ele ment 4 is placed into position underneath the bracket or lug 4. A compression spring 13 is arranged on this bolt so as to permit an adjustment upward or downward of the element' underneath, thus permittin it, under stress, to be sna ped into one 0 two positions in which t e frets 5 fall into opposite furrows 5', 5' on the face of the said element 4'. In addition to this rotative movement, a hinge movement is permitted on the rivets '9, 9, passing through the eyes 9, 9', and connecting the lugs 7, 7 with the legs 14, 14 of the device. The projections 10, 10, snapping into the depressions 11, 11 of the lugs, are

designed to hold'the device inthe position shown in fulllines in Fig. 1 sufliciently rigid for urposes of standin the machine vertica y as shown. Snapping into the detent 18 is suificient to stand the machine at an angle of about degrees, or holds the su ports in the working position, suflicient y ri 'd as shown in dotted lines.

he general utility and operation of the a device may now be explained. A pair of rollers 16, 16 similar to the ones on the framework of the device described, are found on the'cross-head of the machine to which they are to be attached; onl one of these rollers v is shown in the view w ich is taken endwise of the floor tool 22. This cross-head floor tool 22 has a swivel joint 23 rmitting free rotation on the tube or han le 1 of the del3 vice, For the ordinary working position of the bag type machine, the adjustment rollers are swung directly back so that the machine sits at an angle of about 45 degrees, as shown in Fi 8. Likewise the tank or is shown in Fig. 9, where the adjustment rollers are swung directly back.

Where it is desired to cleanunder fumiture, however, the entire frame of the machine is rotated through an arc of about caddy-form mac ne in the working positiondegrees on the swivel joint 23, thus bringing the sweeper on its side. It is apparent, then, that in order that the roller bracket su port should function as heretofore, it sho d be rotated in an opposite direction about 90 derees, which is accom lished by a stress ringing the frets out 0 their then occupied furrows to a corresponding set of furrows at the required angle which is turned. The rollers 16, lfi-are now again in position, so that there are four rollers, two at the crosshead and two at the roller supports, resting upon the floor, in the plane 24.

By the term caddy form, as em loyed in the present specification, I have re erence to a type of cleaner in which the dust collector is housed within a ri id tank or can, as dis tinguished from the ag type of cleaner in which a flexible bag is employed for this purpose.

By the term cross-head floor tool, I have reference to a tool which extends laterally on both sides of the cleaner handle.

Having thus described the invention and the operation thereof, what I claim and desire tosecure by Letters Patent is:

1. In combination with the suction producing, means of an air-way cleaner, a casing for said means, a cross-head floor tool rotatively mounted with reference to said casing, and
