CALIFORNIA, A CORPORATION OF DELAWARE u BRI/ISH MOUNTING IOR FRUIT BRUSHES Application led Icy 18, 1930. Serial N0. 451,657.

Thisinvention relates to rotary brushes such as employed in the washing of citrus fruits or the like. In the operation of these machines the fruit isy rolled between 'under 5 brushes and upper brushes. The under brushes are mounted on a rotating frame or wheel and it is now customary to nail the 'brushes alongside of each other in a substantially radial position all around the wheel.

satisfactory as it entails special fitting of the last brush that 1s 1nserted in the wheel. The upper brushes that rest on the upper side of the fruit and asslst in cleaning it are suspended yieldingly 1n a 15 'substantially fixed position and perform their function as the rotary Vframe or wheel rotates. The general object of this invention 1s to provide improved means for mounting and supporting these brushes. As' regards the 20 under brushes, oneV of the objects-of the invention is to provide* simple-'means for removably mounting the brushes in position, thereby enabling the entire circumference of the wheel to be divided'into attaching points for the brushes spaced substantially equidistant all around the wheel.

As regards the upper brushes,it has been customary to nail them to backs that are suspended from an upper frame or spider. One of the objects of the invention is to provide*A improved means for supporting the upper brushes and connecting the brushes together so that they form a substantially continuous ring extending around over the wheel.

Further objects of the'invention will appear hereinafter.

The invention consists of novel parts and combinationslof parts to be described hereinafter, allv of which contribute to produce an efficient brush mounting for fruit brushes. A preferred embodiment of the invention is described in the following specification, while the broad scope of the invention is pointed out in the appended claims. 4 In the drawings: Figure 1 is a 'plan ofa short portion of a washer wheel embodying my invention, cer- 5 section. This view also shows several of the tain parts being broken away or shown in upper brushes lying over the wheel in substantially the position which they occupy when suspended over the wheel in actual use. Figure 2 is a vertical section taken about on the line 2-2 of Figure 1 but showing the 55 brushes in elevation and broken away at points to further-il1ustrate the invention.

Figure 3's a vertical section taken in the plane ofthe line 3-3 ofFigure 1 upon an enlarged scale-and articularly illustratingwu the means for clamplng the' inner ends of the brushes in position.

Figure 4 is'a cross Vsection-through one of the upper brushes taken about on the line 4 4 of Figure 2 and upon an enlarged scale.= c5

Referring more particularly to the parts, 1 represents the lower rotary frame or wheel that carries the lower brushes l2. In applying 'my invention to the wheel, I provide the same with an outer ring 3 andan inner ring `A70 4 and I provide the brushes 2 with backs 5 that are supported near their middle paint on an intermediate ring 6. Between the ends of the brushes and the rings 3 and 4 I pro- .vid an interlocking connection such that the "l5 brushes can be laid into place and held there. One or the other of the rings is provided with a removable clamping ring which when removed will permit all of the brushes to be removed. The brushes are all tapered in -80 form, being smaller at their inner ends. In other words, I provide a plurality of means around the rings 3 and 4 for holding the 'brushes equidistant from each other. In this way a .certain number of brushes fit in the '85 wheel at a uniform distance from each other. This avoids the necessity for fitting in a special brush completing the insertion of the brushes in the wheel,

An suitable interlocking connection may 9 vbe employed between the brushes and the rings. In the present instance I provide the outer ring 3 with a plurality of inwardly projecting pins, such as the pins 7 (see Figure 1),' and these pins are received in a vertical 95 slot 8 formed in the end wall of the brush back.

` These pins 7 project radially inwardly. The other ring, for example the inner ring 4,

is constructedwith a horizontal flange 9 that 10 rojects toward the other ring and which is ocated at the under side of the rin 4f.l This iange is provided with a plurality o? upwardly extending pins 10 and bolts 11 which are received in slots 12 formed at the inner ends of the backs 5. After all the brushes are in place a clampin-g ring 13-is laid over their inner ends and fastened down by wing nuts j 14. A' suiiicient number of clamping bolts 11 are employed to insure that t e clamping ring 13 will be securely held in place.

The outer ring 3 may be also of angle iron form but with its flange 15 disposed upwardly. In placing-the brushes in position their lower ends would be aligned under the iange 15 with the brush back resting on the intermediate ring 6 and the brush is then swung in a vertical plane on the ring 6 asa fulcrum so as to cause the outer end of thebrush to move upwardly against the under side of the ange 15, the inner end of lthe brush becoming depressed against the upper face of the flange 9. Brushes constructed as described can be manufactured at very small increase of cost and they greatly reduce the amount of-labor necessary in placing them Iin the wheel. Furthermore, any worn brushes can be very readily replaced by a new brush or brushes.

' Above the rotary wheel 1 there are provided a plurality of upper brushes 16. Upper brushes such as these are usually supported on chains 17 from an upper frame or spider 18. It is the customary practice to nail or otherwise 'attach these brushes to their hangers. According to my invention, I secure the backs of these brushes to brush carriers preferably in the form of plates 20 having the shape ofthe brush and provided at their sides with dogs 21 that project down on the sides of the backs and hold the same'in place. This `enables a single fastening device, such as a screw 22, to be inserted from above, passL ing downwardly into the brush back.`

l According to my invention I link these carrier plates 20 together and ,this is preferably accomplished by connecting the lug 21 by means of hinge pins 23. For this purpose, i

the hangers are constructed with two lugs 21 on each edge, the lugs on one side, being suf- Aficiently far apart to enable them to receive between them the lugs on the next adjacent hanger plate. The hanger plates or carriers 2 0 are all tapered so that their side edges are disposed -substantially Vradially from 'the center of the wheel and in this way the conyIlected brushes form an arc about the center of the wheel. The hanger plates 20 are supported on the chain 17, preferably by hooking the lower ends of the chains into perforated lugs 24 on the ends of the hangers. l

It is understood that the embodiment of -th invention described herein is only one of the many embodiments this invention may take, andI do not wish to be limited in the practice 1,a51,4sc
