As is shown particularly in Figs. 55

4, 5 and 9, the band is provided with a pair of lugs 29 on opposite sides of the caddy, each lug having a divergent cam face 30 so arranged as to spread the legs 3| and 82 of the support when the legs are brought to right angles to' the body of the caddy. The legs are hingedly secured by means of hinge pins 33 extending into the lugs 28. The legs are composed of resilient material which is adapted to withstand torque and each includes a web portion 34 of channel shape and each is provided with flat portions 35 and 36 on which there is no web. The legs are connected by a two-part brace member 31 hinged at 38 and constituting a toggle Joint. The lower portions of the legs are provided with telescoping members "and 40, respectively, which are parallel to the floor, the member 39 fitting over the member 40. Bumps or projections 4i are provided on the inner member while a pair of apertures or indentations 42 and 43 in the outer member cooperate therewith and are adapted to serve as blind catches to hold the channel members either in extended or in contracted positions, as indicated in Figs. 4 and 5 respectively. Rollers 45 are provided which may be of the general type disclosed in my Patent No. 1,541,280, dated June 9, 1925, without the spring shank.

The center rivet or axle of the roller is riveted to the corners of the channel shaped legs, which corners are reinforced so as to make them strong enough to sustain the riveted ends of the roller axle or spindle.

Operation When the support is swung so that the legs are at right angles to the central axis of the caddy, it will be apparent that the cam action of the divergent face 30 of the lugs 25 to which the legs of the support are pivoted, will cause the legs to spread to the fullest extent as illustrated in full lines in Figs. 1 and 4, and in dash lines in Fig. 3. A detent 46, projecting from the band 28 and located near the lugs 29 serves to limit the swinging movement. The. legs are forced apart to their limit and are held in such position by the brace 31 and by the bump or detent 4| in the inner channel member 40, engaging in the indentation'42 in the outer channel member.

To collapse the support the toggle connection is first broken at 38 as indicated in dot and dash lines in Fig. 4, whereupon the bracket may be swung to the inoperative position shown in Figs. 2 and 3 and fully collapsed, as indicated in Fig. 5.

It will be apparent that there is a torsion in the flat portions of the supporting legs and in the brace 31 but these parts being made of resilient material will withstand the torque and said torque tends to return the legs by a swinging action to the open position as soon as released. The blind catches in the channels ,38 and cause them to remain in open or in closed position but the catches may be overcome by the application of sufficient force.

In Figs. 11, 12 and 13, the support is shown as applied to a different form of cleaner. As illustrated, the reference character A denotes generally a floor tool which includes a motor housing 43, a fan casing 44 having an outlet 45 and an intake 60. A suction box 45 in the lower portion of the floor tool is separate from the interior of the fan casing and is provided with an outlet 41 for dust laden air.

Reference character B denotes generally a cylindrical housing or caddy hingedly connected to the floor tool A by means of bracket members 48 and 48, while the interior of the caddy is connected to the fan casing inlet 80. by means of a collapsible tube Si or equivalent device which permits the caddy to be swung in a vertical plane with reference to the floor tool. The caddy houses a dust filtering device (not shown) which is preferably connected to a transparent removable cap or cover 50 and is adapted to be withdrawn therewith by means of a tubular member 5] which serves as a handle grip and also as an inlet pipe for dust laden air which is drawn into the dust filter within the caddy B. The handle 5| is preferably secured to the cap 80.

A flexible hose extension 52 is shown connected to the end of the handle grip ii and its opposite end may be connected to the outlet pipe 41 of the suction box, as illustrated in Fig. 12 or may be provided with a nozzle or other application tool 53 as illustrated in Figs. 11 and 13.

The caddy B is shown as equipped with a collapsible support 0, similar to what has been described in connection with Figs. l-10, inclusive, which is attached to the caddy by means of a band 54 surrounding the caddy and adjustably connected as described in connection with Fig. 4. A suitable limiting stop 55 is provided on the band adjacent the point of attachment of the legs of the swinging support.

As illustrated in Fig. 11, the caddy is held in vertical position by tightening the hinge connection between the bracket arms 48 and 49. The hose 52 may then be used for cleaning walls, draperies or the like, the bracket or support C being collapsed and swung out of the way. The handle may, if desired, be supported by a suitable hanger, such as illustrated in Fig. 2.

In Fig. 12 the support C is shown swung to a position at right angles to the central axis of the caddy and in such position the legs are extended by the cam action of the lugs to which the legs are secured. The bracket arms 48 and 49 are preferably loosely connected in this instance so that the caddy may be fully swung up or down. When swung downwardly the rollers of the member C may rest upon the floor and support the weight of the caddy in cooperation with the rollers of the floor tool, to facilitate movement of the entire apparatus across the floor without the necessity for the operator bearing any of the weight thereof.

In Fig. 13 the bracket C is shown as resting upon the floor and as supporting the caddy while the hose extension 52 and the working tool or nozzle may be used for floor cleaning or other purposes. The tool 53 may be of the 90 angle type as shown in my Patents Nos. 1,403,524 and 1,994,871. Such tool may be removed when the hose pipe is to be connected to the outlet 41 of the suction box as in Fig. 12, and in such case the member 53 may be attached to the end of the outlet pipe 45 and serve to direct air against the motor casing 48 to cool the same.

The invention has been described in detail for the purpose of illustration but it will be understood that variations and modifications may be resorted to without departing from the spirit of the invention.

I claim:

In a device of the character described, a tubular body member, and a collapsible and extensible hinged bracket adapted when extended to support the body member in inclined position, and when collapsed to permit the body member to lie flush against a plane surface; said bracket Fur mi, J

together when the legs are folded into inoperative position, and a pair of telescoping tubular members connecting the ends of the legs, said members having coacting means for holding the legs close together or spread apart in the col- I lapsed or expanded positions respectively.
