- 2 Claims.

This invention relates to a pan washing machine, and more particularly tosuch a machine adapted for the washing of pans utilized in cooking or the like.

A primary object of the invention is the provision of an improved pan washing machine, including a plurality of rotary brushes, which brushes are doubly rotatable, both about their own axes and about a common-central axis.

An additional object of the invention is the provision of such a device wherein the relative position of the brushes may be varied to accommodate a variety of sizes of pans.

A still further object of the inventionis the provision of means in association with such a device for supplying a cleaning fluid, such as water or the like, to the pans during the washing and scouring operation.

A further object of the invention is the provision of such a device which will be sturdy and durable in construction, reliable and-efficient inoperation, and comparatively simple and inexpensive to manufacture and operate.

Still other objects reside in the combinations of elements, arrangements of parts, and features of construction, all as will be more fully pointed out hereinafter and disclosed in the accompanying drawings, wherein there is shown a preferred embodiment of this inventive concept.

In the drawings:

Figure 1 is a side elevational view of one form of device embodying this invention, certain concealed parts thereof being indicated in dotted lines,

Figure 2 is an end elevational view of the device of Figure 1 as viewed from the left,

Figure 3 is an end elevational view of the device shown in Figure 1 as viewed from the right,

Figure 4 is a sectional view taken substantially along the line l4 of Figure 1, as viewed in the direction indicated by the arrows,

Figure 5 is a sectional view taken substantially along the line 5-5 of Figure 3, as viewed in the direction indicated by the arrows, and

Figure 6 is a sectional view taken substantially along the line 6-6 of Figure 4, as viewed in the direction indicated by the arrows, but showing the outer plate in position.

Similar reference characters refer to similar parts throughout the several views of the drawmgs.

Having reference now to the drawings, there is generally indicated at H) a base plate, which carries a supporting member ll, having a, bearing member l2 thereon, which supports an interme- 2 diate portion of a rotatable hollow shaft l3. The extremity of the shaft I3 is journaled for rotation in a bearing member l4, secured as by bolts IE, to

' a supporting plate I6, which is secured in any desired manner, as by welding IT, to the base 10. The shaft [3 carries a gear 18, by means of whichit is adapted to be rotated, any suitable mechanism (not shown) being provided to accomplish such rotation. I

Suitably secured to the outer face of plate It, as by welding I9, is a ring gear 20, provided, as best shown in Figure 4, with internal teeth 2 I.

Secured to the shaft l3, as by akey 22, is a plate 23 adapted to be rotated by rotation of he shaft. The outer extremity of the hollow shaft i3 is closed, as by a threaded plug 24, and a plurality of tubes 25 communicate with the interior of the shaft, and extend outwardly beyond the plug 24, for a purpose to be more fully described hereinafter.

The plate 23 has positioned on the inner face thereofa plurality of stub axles 26, as best shown in Figure 6, which axles carry rotatably mounted gears 21 adapted to engage the teeth 2| of the ring gear 20. The gears 21, which are preferably of fiber or similar composition, are adapted to mesh with gears 28, which may be of metal or similar material, which gears are keyed or otherwise suitably secured to shafts 29, which extend outwardly through suitable arcuate slots 30 (see Figure 3) in plate 23. Locking nuts 3| surround each of the shafts 29, extending through the slots 30, and threadedly engage threaded apertures in the extremities of links 32, the opposite ends of which links encircle the axles 26. Brushes 33 of any desired type are adapted to be carried by the shaft 29. Clamping plates 35 are positioned over the apertures 30, and between the plate 23 and the locking nuts 3|, suitable apertures in the plate 35 permitting the lower extremity of the 'nut to be passed therethrough. Guide pins 36 are provided adjacent the plate 35, to guide the path of movement thereof when the shafts 29 are moved in a manner and for a purpose to be more fully pointed out hereinafter.

As best shown in Figure 4, each of links 32 has pivotally secured, as by a pivot 31, to a mid point thereof, an additional link 38, the opposite end of which is pivotally secured as by a pivot 39 to a point of a triangular member or plate 40 coaxially mounted with respect to the tubular member 13, for rotatable movement thereabout. Secured to one of the pivots 39 is an angled link M, at the opposite extremity of which is a handle member 3 42 which extends exteriorly of the plate 23 through an arcuate slot 43 (see Figure 3).

From the foregoing, the operation of the device should now be readily understandable. In adjusting the device for a given size of pans, the lock nuts 3| are first loosened, permitting the shaft 29-to1move freely-in the slot3ll. The handle 42 is thenmoved in-la desireddirection, "which through the arm 4|, moves the triangular plate 40, which, in turn, through the links 38 andi '32; varies the position of the shaft 29 and their associated brushes within the limits defined-by the slots 30. Thus it will be seenthat a variety$of sizes of pans may be utilized in: conjunctionwith the device, the brushes being so placed as toz thoroughly scour the rims ofsuch, pans After the brushes are set in the desired position,"'the lock nuts 3| are tightened, water or otherbsuitable cleansing fluid introduced through the hollow shaft 13, fromwhich it escapes through-v the tube 25-to the interior surface of the pan, andthe shaft- I3 rotated relatively rapidly. This rotation -will vcause the plate-23 to rotate, and hence the brushes to-rotate about acommon -axis,v.-while simultaneously the'engagement ofthe gears'Z'I With the teeth 21 of ring gear 20 will, through the gears'28, occasion rotation of the shafts 29,

and hence their associated brushes each about its own individualaxis.

Thus it. will be seen, that there is herein'provided'an improved cleaning device particularly adapted for use with circularfiobjects, such as cooking pans, or the like, which accomplishes all the objects oi-this invention and others, including many advantages of great practical utility and commercial importance.

As many embodiments maybe "made OfithiS inventive concept, and as many modifications may be made in the embodiment "hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative; and not in a'limiting "sense,

I claim:

1. In a pan-washing device, in combination, a hollow rotatable shaft, a stationary ring gear surrounding said shaft, a plate rotatable by said 5 shaft, driver gears mounted on said plate meshing with said ring gear, driven gears meshing Withvsaid driver gears; brushes' rotatable by said -;second=mentioned gears, tubes extending from said shaft adjacent said brushes for introducing mashing fluid to a pan, and means for varying the relative position of said rotatable brushes with respect to said ring gear, said last mentioned 5 11183118 comprisingran apertured plate positioned onv-saidkshaft, :means including links coupling 15. pairs of. driven. and driver gears for rocking move- ,ment, and rods.v connecting said apertured plate and' said links. "2;:The combination of claim 1 and said first mentioned plate being attached to said shaft for rotation .therewithvand shaving slots therein, shafts attached tosaid driven. gears mounting .said brushes,.and sa-id last mentioned shafts extending through the slots in said cover.
