This invention relates .to an improved household power unit, the novel features of which will be best understood from the followin description and the annexed drawings. ln the drawings, I have shown selected embodiments of the various features forming the invention, and referring thereto; 7

Fig. 8 is a section of the ring only, taken on the line 8-8 of Fig. 7.

I have shown the invention as comprising a movable'base 1 which may be provided with a plurality of rollers 2 whereby the base and the parts supported thereon may bereadily moved to any desired position when in use, and may -be easily stored away in an out of the way place when not in use. Extending upwardly from the base is a standard 3 upon which I'have shown a vertically slidable sleeve 4 supporting a shelf 5 which may be rotated about its pivot 6 and secured in any desired position. Suitable handles 7 and 8 are provided forclamping the shelf in such a desired position, in which it may support a container which is to be 'used with the unit.

Disposed on top of the standard is a gear casing 9 supporting a motor 10. The details of the gearlng in the casing are not shown,

, because they may vary quite widely. It is deemed sufficient to say that the motor has a shaft 11 upon which is mounted a pu11 ey 12, and the gearing includes a shaft 13 carrying a pulley 14 which is driven by means of a belt running over the two pulleys. By this arrangement the various gears and shafts in the casing are given their movement. The casing is preferably provided with a plural- 5 1ty of power outlets, each in the form of a rotatable shaft. In this form, I have shown two

shafts

16 and 17 extending from opposite sides of the casing, and each surrounded with a shroudso as to protect the shaft and to pre- Vent accidental engagement thereof by the fingers of the person employing the unit.

Each of the shafts l6 and 17 is provided with a clutch element, a suitable type of, which is shown in Fig. 6 In this figure I have shown as the shaft 16 as provided with oppositely disposed recesses 18 which form extensions of a central recess in the shaft. Within the central recess may be placed a shaft 19 of a device which is to be operated by the shaft 16, and this shaft 19 is provided with oppositely extending pins 20 which may be received in the recesscs l8.

operated from the In this form, I have shown hinge members in the form of pins 21 adjacent one outlet,these hinge members being adapted to cooperate with hingemembers 22 on a bracket 23 which can be readily lifted from the hinge pins 21 and can likewise be placed on the pins by vertical movement. The bracket may be releasably held in position by means of a spring latch indicated by a pin 23 coacting with an ear 24 on the bracket. By this arrangement the bracket and any device carried thereby may be easily swung out of operative engagement with the power unit, in case of any accident such as catching the operators fingers in any of the moving parts. Adjacent the other power outlet I have shdwn ears 25 having apertures therein to receive pins 26 ona ring 27. This 5 ring forms another kind of bracket adapted to support other types of devices tobe operated from the power unit. It may here be "said that the two

outlets

16 and 17 will ordinarily be operated at different speeds by suiti that by this arrangement the bar 31 may be head on the pin 29in the slot bar 31 and prevents lifting able arrangement of the gearing in the easin 9.

I will first describe the best shown in Figs. 3 and 4. This bracket is preferably in the form of the ring 27, and has the pins 26 secured thereto.- It may thus be easily placed in position and removed by a simple vertical movement. If desired, the ring may be provided with inwarly extending lugs 28 to engage a container which may be supported thereon. Extending upwardly from the ring on opposite sides, are headed pins 29, and the line between these pins is preferably at right anglesto axis of the shaft 19 on the device supported on the ring. In the form shown, this device is exemplified as a beater 30, this device being supported upon a transverse bar 31 which has slots 32 and 33 at its opposite ends, to receive the pins 29.

It will be noticed that the slot 32 opens towards the casing, while the slot 33 opens towards the end of the bar, or at right angles to the slot 32. The slot '33 is deep enough so that when the parts are in operative position the pin 29 disposed therein does not touch the bottom of the slot. I have found placed in position by sliding it lengthwise with one pin 29 in the slot 33, and then by rotating it about that pin until-the other pin enters the slot 32 and the clutch elements on the

shafts

16 and 19 come into engagement. A latch 34 may be provided to aid in holding the bar in position.

The shaft 19 will always be rotated in one direction, which in this case is counterclockwise, as indicated by the arrow in Fig. 7 The 33 engages the of that end of the bar, an action which the rotation of the shaft tends to cause. There is also a tend-,

ency to rotation of the bar about the center of the ring, and this rotation is prevented by the pin 29 in the slot 33 and also by the latch 34.

In Figs. 7 and 8 I have shown a different embodiment of the structure just described, in which the bar 31 is provided with a slot 33 adjacent one end extending in a direction at right angles to the shaft 19 and receiving a headed pin 29. In this form the bar is provided at its other end with a hole to snugly receive a headless pin 29. By this arrangement the head on the pin 29 will prevent the lifting action referred to above, while rotation about the center of the ringis prevented I by both the pin 29 and the pin 29.

I will now describe the bracket shown at the left of Fig. 2, this bracket also being shown in plan in Fig. 5. This bracket is designed to support a container such as a pan 35 having a rim 36 of the usual beaded form. On the side of the bracket'adjacent the casing this beaded rim is received within grooves 37 in the bracket, and on the opposite side the form of bracket rim is received in forked cars 38. These ears are spaced relatively close together and mounted between them on a pivot 39 is a latch 40 having a lipadapted to catch under the beaded rim, as plainly shown in Fig, 2.

The latchis also provided with a'projection I device just described above, a container 1s placed with its beaded rim in the grooves 37 and then the outer portion of the rim 1s swung upwardly be-' 38. The latch 40 tween the forks of the ears may be swung away of the rim. The handle 44 of course is raised to a substantially'vertical position and then it may be used to swing the latch on its pivot 39 into and out of engagement with the rim. The bottom of the lip on the latch is adapted to permit the rim to force the lip and latch outwardly in a well-known manner.

Afer the rim is brought into position, the

be used to bring the latch v with the rim by movement about the pivot 39, and then the handle is depressed into engagement with one of the camsurfaces 45. This will lock the container in position wherein it may be used to holdany substance which is being acted upon by the handle 44 may into engagement to permit this movement 7 device 46. This device in turn is actuated by ashaft' 47 having a clutch 48 adapted to cooperate with corresponding clutch elements on the shaft 17. The above arrangement is one which will simpl and easily support the container without de orming the container or its rim.
