Patented Sept. 30, 1952 SUCTION CLEANER RUNNER AND BRACKET I ASSEMBLY All en P. Cawl, Painesville, Ohio, assignor to General Electric Company, a corporation of New York . Application June 4, 1949, Serial No. 97,289

4 Claims.

This invention relates to suction cleaners of the tank type, and more particularly to a runner and bracket assembly for slidably supporting the tank of the cleaner on a surface.

Tank type suction cleaners, to which this invention relates, conventionally include a motor or other suction-creating means and a suitable dust separator within a tank. This tank is connected through a flexible hose to an appropriate cleaning nozzle. For convenience in operation,

it is desirable for the operator to be able to move the tank from one position to another by merely pulling on the flexible hose. Thus, a convenient supporting structure is required for the tank which will permit it to be readily moved over a surface. I

It is, therefore, a primary object of my invention tovprovide a runner assembly which will support the tank itself in a stable position but of contact with the surface upon which the cleaner is to rest, and which will permit the tank to be readily moved.

A further object of my invention is to provide such a runner assembly which is economical to manufacture and assemble and readily attachable to a tank of a suction cleaner.

It is also an object of my invention to construct a tank supporting runner a'ndbracket assembly presenting smooth exposed surfaces.

In accomplishment of the foregoing objective, a feature of my invention consists in slidably supporting a cleaner tank on a pair of runners having a substantially 'C-shaped' 'cross section with the open face of each runner facing inwardly so that the exposed or outer surfaces are smooth. Another feature of my invention consists in the use of improved-bracket members attachable to the under surface of the'tank and which have end portions quickly connected to the runners by relative rotation of approximately 90 degrees between bracket and runner.

The features. of my invention which I believe to be novel are set forth with particularity in the appended claims. My invention itself, however, both as to its organization and use, together with further objects and advantages thereof, may best be understood by reference to the following description taken in connection with the accompanying drawing, in which Fig. 1 is a front elevation of a tank type suction cleaner embodying my invention; Fig. 2 is an end elevation of the device shown by Fig. 1 with one of the runners shown in cross section; Fig. 3 is a perspective view of my improved runner and bracket assembly; and Fig. 4 illustrates a' portion of the runner with part of its surface cut away to illustrate the method of attaching a bracket end to a runner. Referring to the drawing, in Figs. 1 and 2 I have shown a tank. I of a suction cleaner. This tank serve as an enclosure and mounting means for a motor or other suction-creating device and a dust separator toaccumulate the dust anddirt picked up in the. cleaning operation. Tank lhas a suction opening into which a flexible hose 2 is inserted, hose 2 leading to a cleaning tool (not shown). A handle 3 is provided onthe top of tank I so that the cleaner may bereadilymoved from place to place, such as between. rooms. However, during normal cleaning operations with.- in a given area, it is inconvenient. to pick up tank I by means of handle 3 for short movements of the cleaner. For this reason, I-find it desirable to mount tank I on runners which are slidable over a surface. This permits the user of this appliance tovmove the tank from placeto place by merely pulling on suction hose 2.

As clearly shown by Fig. 2, tank I is supported above a surface on a pair of runners 4 and .5.

These runners present a substantially flat outer surface and the edges are rolled inwardly so that a completely formedrunner member has a substantially C-shaped cross section. Thus, the exposed runner edges present a smooth surface which will not catch or drag as the tank is moved about from place to place. As shown by Fig. 3, the end portions of each runner are sloped upwardly from the bottom edge, as at 6 and i, so that the tank may be moved readily in either direction and any irregularity or unevenness on the surface upon which the device is restingwi11 not interfere with movement.

Runners 4 and 5 are attached to tank I by means of supporting brackets 8 and 9. The intermediate portion of each bracket is shaped to conform substantially with the-under surface" of tank '1. Each bracket is also provided with a pair of apertures l0 and H through which fastenin devices [2 and I3 extend for attaching the bracket members to the tank. Obviously, any suitable fastening may be used between the brackets and the tank.

r The end portions of each bracket are preformed so that the bracket may be attached to the-runners by a simple rotational movement of each bracket with respect to the runners. As shown by Fig. 3, each end of the flat metal strip forming a bracket is bent downwardly to form a foot l5 so that the tank will be supported in spaced relation with respect to the surface upon whichthe device rests. However, a part of the'strip near each end is out to permit an ear I4 to extend upwardly. The upper extremity of upstanding ear II and the lower extremity of foot I5 are so dimensioned as to be substantially equal to the inside dimension of a runner. However, the lateral width of the strip forming each bracket is slightly less than the distance between the rolledover edgesof a runner. This construction permits the end portion of the bracket formed by ear I4 and. foot I5 to be inserted into the open face of the C-shaped runner by rotating the bracket member approximately 90 degrees from the position shown in Fig. 3. Then by rotation back to its initial position, as shown by the arrow in Fig. 4, the outer extremities of ear I4 and foot I5 on the end of each bracket member are engaged within the rolled-over edges of the runner with a tight fit.

To facilitate the rotation to bring the end of the bracket into engagement inside of the C-shaped runner, a corner I8 of foot I5 is rounded; and likewise a corner I? of ear I4 is rounded. Then to maintain the bracket in its final assembled relation in the runner, a notch I8 is cut from each of the foot portions I5. 'By use of a prick punch the runner may be dimpled into this notch to prevent both rotational movement of the bracket with respect to the runner and also longitudinal displacement.

V The manufacture and assembly of my improved runner and bracket assembly is greatly facilitated. The runners and the brackets for this construction may be prefabricated andpreformed to their final shape by mass production methods. At the time of assembly,.the brackets are positioned so that the runners may be placed over the bracket end portions. Then, while they runners are held stationary, the brackets are rotated approximately 90 degrees into locking and engaging relation with the runners. This entire operation can be readily adapted to automatic or semiautomatic performance by machine because of the simplicity of the components. By the dimpling b of each runner'at each of the notches I8, the

runners and brackets may be more rigidly connected together. Finally, the runner and bracket assembly is attached to tank I by means such as y the fastening devices 'I 2 and I 3.

From the foregoing, it-is seen that I have provided a mounting and supporting structure for the tank of a suction cleaner permitting it to be slidably moved over a surface. My runner and bracket assembly results in increased stability for the tank, while at the same time presenting a smooth outer surface. This is especially true when the runner members are made from a chromium plated sheet metal. v This assembly also results in greater economy of manufacture and assembly since the component parts may be prefabricated in their final form by mass production methods, while permitting the bracket members to be readily attached to the runners and then the entire assembly to be secured to the tank of the cleaner.

While the present invention has been described by reference to a particular embodiment thereof, it will be understood that numerous modifications may be made by those skilled in the art without actually departing from the invention. I, therefore, aim-in the appended claims to cover all such equivalent variations as come within the true 7 spirit and scope of the foregoing disclosure.

What I claim as new and desire to secure by Letters Patent of the United States is:
