Lockwood, Portland, reg., assignors to The Regina Corporation, Bahway, N. 1., a eorpora tion of New Jersey Application August 15, 1935, Serial n 3034a 11 Claims. (01. 242-85) means of a cable or cord, one end of which is connected to the switch mechanism of the apparatus and the other end of which is adapted to by means of a connecting plug carried'thereby to an electrical outlet. Such cable, when the apparatus is not in use, is usually wound upon the handle of the ambulant frame by means of a pair of hooks secured upon the handle, one of such hooks being secured to the lower portion of the handle so as to have its free end, bent outwardly from the handle, extend downwardly, the other hook being secured to the handle near its upper end with its bent free end extending outwardly and-directed upwardly. The cord or cable is then wound about the hooks by overlapping loops and retained im position upon the handle of the-apparatus by said hooks. In releasing such cable, it has been necessary to unwind successive portions thereof by the tedious operation of unwinding the successive loops necessitating the bending of the operator so as to disengage successively the ends of the loops from the upper and lower hooks.

While it has been proposed to reduce the tediousness of this operationv by providing one of the supporting hooks, usually the upper, of a construction which permits such hook to be brought 35 into a position'in which it will release the successive loops of the cable with a single manipulation of the hook, for instance, by having the same hinged upon the handle at or near its point of securement thereon, such a releasing device is characterized by certain disadvantages, for instance, in cost of manufacture, cost of application to the handle, and the complicated nature of its operation, including the necessity of returning it to its original position after therelease 45 of the cable.

In accordance with our invention, we provide a cable releasing device extremely simple in construction, cost of manufacture, application to the In accordance with .our invention, we provide 55 acable releasing device which constitutes a hook cleaner.

for supporting the wound loops of the cable and necessitating no more than the grasping. of the extending portion of the hook and its rotation to a positionin which the extending free end of the hook is pointed downwardly, thereby eilfecting the 5 automatic releasing of the wound loops of the cable from the hook.

A particularyembodlment of our invention is -illustrated in the accompanying drawing, in

j latter broken away to illustrate the mounting 2, structure; Fig. 4 is a section on the line 4-4 of Fig. 3; and Fig. 5 is a detail of the portion of the shaft upon which the hook is rotatably mounted showing the split washer by means of which a spring retaining cup is secured to the shaft.

Referring more particularly to the drawing, in which similar reference characters identify similar parts in the several views, 6 designates generally the vacuum cleaner apparatus mounted uponan ambulant frame from which extends upwardly the tubular handle I to the upper end of which is secured in the usual manner one end of the cable 8, the other end of such cable being provided with the usual connecting plug .9 adapted to be inserted into an electrical outletfor supplying current to the electric motor of the vacuum The usual dust bag It is supported upon the handle by means of spring I l secured upon a hook l2 extending from the handle 1. Near the 40 lower end of tubular handle I and secured thereon is a hook member 13 riveted in the usual manner to such handle and having its hook portion l4 extending downwardly.

At a point remote from the lower hook l3 and from the upper end of the handle is mounted the upper cable supporting hook ii. In accordance with our invention a shaft l6 extends through the tubular handle 1, through aperture ll at one side thereof and through aperture ill at the other side thereof, the end of the shaft l6 extending beyond the aperture l 8 being formed into the hook l2 for supporting the dust bag I 0 by means of a ring at the upper end of the spring 'I i.

The surface of the tubular handle I immeindented as shown at I3 soas to provide a seat for the hook l2 and thereby prevent rotation of said hook and of the shaft it when the cable releasing device is operated as hereinafter described.

The end of the shaft l3 extending through and beyond the aperture I! on the other side of the tubular handle I is provided with a tapered head 20 and a groove 2|. The hook member i 5, shown in enlarged detail in Figs. 2 and 3, comprises a body portion 22 of substantially the same configuration and curvature as the surface of the tubular handle I, the hook member 23 extending from such body portion. A compression spring 24 is positioned over the shaft l6 so as to have the widest convolutions thereof bear against the 3 outside surface of the body portion 22 of the hook element, the other end of the spring, constituting the convolution of smallest diameter, bearing against a cup 25 secured upon the shaft It by" means of the split washer 28 which, after the cup 25 has been placed over the shaft, is clamped upon the shaft adjacent the tapered end 20 and within the groove 2i, the washer being seated within the groove and compressed therein for securement within the groove.

The operation of our novel cable releasing device is as follows:

When the cable 8 has been wound in the usual manner so as to secure the ends of the successive loops thereof between the hooks I3 and i5 and it is desired to release such cable, the hook portion 23 is grasped and the entire hook is rotated about the shaft Hi from a position illustrated in full lines in Fig. 3 to its position illustrated in dotted lines in such figure; 1. e. by turning the hook in an arc of approximately degrees. This is accomplished by compressing the convolutions of the spring 24, the operation being effective to bring the wider convolutions of the spring over the narrower convolutions thereof, and without any rotation of the shaft l6, which is maintained in its original position by reason of the indenture in the side of the tubular handle I, in which indenture the dust bag hook i2 is retained. When the hook portion 23 has been brought to the dotted position in Fig. 3, the ends'of the loops of the cable will be released from the upper hook, as will be apparent from a mere inspection of the drawing. The hook l5 by means of its element 23, may be rotated in either direction as shown by the arrows in Fig. 2.

Our novel structure as hereinabove described is characterized by simplicity in construction and facility in operation, the novel means for mounting the spring 24 and the securement thereof upon the shaft I 6 being effective to prevent rotation of such spring to any degree which will interfere with the effective operation of the cable releasing device. Our novel structure also prevents the rotation of the hook I2 upon which the dust bag "I is supported by reason of its securement in positive locked position by the indentation I! in the tubular handle 1. The provision of the cup 25 and the particular mode of its securement upon the end of the shaft l6 constitutes an important feature of our invention as they prevent the working loose of the structural elements of our device upon repeated use as would occur if an ordinary nut were secured upon threads upon the end of the shaft to retain the spring in position.

While we have described a particular embodiment of our invention as applied to the tubular handle therefor and a cable, comprising a shaft passing through said handle, and a support for the successive loops into which the cable is adapted to be wound, constituted of a hook adapted to be brought from its supporting position in -which the hook element thereof extends upwardly to'a position in which said hook portion is directed downwardly, by the turning of said hook portion in an arc of approximately 180 in planes perpendicular to the said shaft and parallel to the axis of the handle.
