1 Claim. 1

My invention relates to improvements in scrubbing and washing machines for the lids of cheese boxes. 7

By Way of premise, the cheese box lids with which my invention is concerned are round, large Wooden covers with wooden strips on one side and are hard to handle and scrub clean by hand, as is the common practice.

With the foregoing in mind, it is the primary object of my invention to provide a simply constructed rotary brush, scrubbing and washing machine which will thoroughly clean such lids on both sides quickly and thus save considerable time and'labor in rendering the lids sanitary and fit for repeated use.

Another object is to provide a machine for the above purpose which is economical to service,

operate and manufacture and not liable to get out of order under prolonged use.

Other and subordinate objects, within the pur View of my invention, together with the precise nature of my improvements will be readily understood when the succeeding description and claims are read with reference to the drawings accompanying and forming a part Of this specification.

In said drawings:

Figure 1 is a view in plan of my improved machine in the preferred embodiment thereof;

Figure 2 is a view in side elevation of the same;

Figure 3 is a, fragmentary view in vertical transverse section taken on the line 3-3 of Figure 1 and drawn to a larger scale;

Figure 4 is a view in transverse section taken on the line 4-4 of Figure 3.

Referring to the drawings by numerals, my improved machine comprises a rectangular, skeleton frame 1 including a pair of upper angle iron side bars 2 supported at the ends thereof by legs 3, of tubular stock pipe, connected in pairs on opposite sides of the frame I by longitudinal lower side members 4, also of stock pipe. A cross pipe member 5 connects the legs at opposite sides of the frame I at what constitutes the front of the machine, and a similar rear cross pipe 6 connects the legs at opposite sides of the machine at what constitutes the rear of the machine.

A pair of upper and lower cylindrical vertically aligned brushes H), H extend transversely of the frame I in the transverse center thereof, the

brushes, having flexible bristles l2 extending from a tubular core [3. The brushes it, it are spaced slightly apart, and parallel, with the upper brush I0 slightly smaller in diameter than the lower brush l l for a purpose presently explained. lJhe brushes III, II are mounted as follows:

The core l3 of the upper brush I0 is fixed on a shaft [4 having its ends journaled in bearings I5 bolted, as at I6, to short angle bars ll supported at the ends thereof above the side bars 2 parallel therewith by vertical rods l8 threaded into the side bars 2 with retaining nuts 19 thereon. The lower brush H has its core l3 fast on a shaft 26 journaled at its ends in bearings 2| suitably fixed on the side bars 2.

A drive for the brushes in, II rotate the same in the same direction as indicated by the arrows in Figure 3, and the upper smaller brush l0 faster than the larger one H to feed a cheese box lid 22 therebetween from the front to the rear of the machine. The brush drive comprises a suitable electric motor 25 supported on a platform 26 suitably bolted, as at 21, on one of the side members 4. Twin belts 28 extend from a twin pulley 23 on the armature shaft 30 of the motor 25 around a twin drive pulley 3| on one end of the shaft [4 of the upper brush l0. One run of the belts 28 drives a twin pulley 32 on one end of the shaft 20 of the lower brush H. The twin pulley 32 is larger than the twin pulley 3! so that the lower brush H is driven slower than the upper brush l0 and the speed of the upper brush [0 is considerably faster than that of the lower brush. As will be clear, the arrangement of the belt drives the brushes H), H in the same direction.

A pair of laterally spaced, parallel lid supporting rollers are supported in a common horizontal plane at what constitutes the front of the machine, in front of the brushes I0, H and by a pair of horizontal angle bars 36 at the sides of the machine in which the ends of said rollers 35 are journalled, said bars 36 being supported above the side bars 2 by vertical rods 31 welded, as at 38, to said bars 2 and threaded into the angle bars 36 with retaining nuts 33 thereon.

A pair of lid supporting rollers 43, like the rollers 35 are supported at what constitutes the rear of the machine, in the rear of the brushes ill, I! by angle bars 4| like the bars 36 supported in the same manner by vertical rods 42. As will be understood, the rollers 35, 40 are disposed in a common horizontal plane to support the lid 22 horizontally and spaced substantially equidistantly between the cores l3 of the brushes 56, H.

A metal brush guard of inverted trough shape covers the upper brush in for confining water fed to the upper brush and by means presently described, and said guard has its ends 46 resting on a pair of canvas splash sheets 41, 48 depending from the bars ll with upper edges underlying the bearings I and secured to said bars I! by said bearings, the sheet 4'! being similarly secured under one of the bearings 21 with the shaft extended therethrough. The sheet 48 is hung from the side bars 2 by rope loops 49 and is similarly secured to the lower member 4 by loops 56. The sheet 41 on the side of the frame I opposite the motor is longer than the sheet 41' to protect the belts 25 in a manner which will presently be clear.

A metal water catch trough 5| underlies the lower brush II with the lower portion of said brush II running therein and has its ends 52 loosely suspended on the shaft 20 of said lower brush II.

A Water feed pipe 54 is extended through one end of the splash guard is to extend longitudinally along and over the top of the upper brush iii to spray water downwardly into the upper brush it. Above the upper brush It? the water pipe 5 has a portion perforated for spraying onto saic. brush. A coupling on the pipe 55 provides for securing thereto a pipe 52 leading from a suitable source, net shown, of hot water under pressure. A branch pipe 58 extends from the pipe 5:3 to the lower portion of one end 52 or" the catch trough 5! to feed water into said trough. A suitably valved drain pipe 59 depends from the bottom of the catch trough 5i for draining water therefrom.

The operation of the described invention will be readily understood. The lids 22 are pushed over the rollers and in between the brushes I3, ii. As the edge of a lid 22 enters between said brushes Ii II, the brushes rotating in the direction indicated by the arrows in Figure 3 feeds the lid rearwardly over the rollers ed. The upper brush it} receives and is saturated with hot water from the pipe 54 and the catch trough filled to a predetermined depth of hot water to saturate the lower brush ii running therein. The saturated brushes I 0, E I act against opposite sides of the lid 22 with a scrubbing or scouring and washing action to thoroughly clean the same. Since the upper brush is rotates faster than the lower brush H, it tends to feed the lid 22 relative to the lower brush II so that the lid moves ahead relative to the lower brush I I which rotates oppositely relative to the direction of feed of the lid 22 whereby to facilitate scrubbing, or scouring action of the lower brush I I against the bottom side of the lid 22 which is usually coated from exposure to cheese and is difficult to clean. The catch trough catches water drained from the upper brush I!) after the lid 22 has passed said brushes. The valved drain pipe 59 provides for draining the catch trough as the occasion may require. The splash sheets 47, 48 confine the water against escape at the sides of the machine and, as will be clear, the belts 28 being outside the splash sheet 4'1, said sheet protecting the same against being splashed by water.

The foregoing, will, it is believed, sufiice to impart a clear understanding of my invention, without further explanation.

Manifestly, the invention, as described, is susceptible of modification, without departing from the inventive concept, and right is here reserved to such modification as falls within the scope of the appended claim.

Having described my invention, what is claimed as new is:

In a machine for scouring and washing box a frame comprising a pair of bars having supporting legs, a pair of upper and lower cylindrical brushe: the upper one smaller than the lower one, means rotatably mounting said brushes on said side bars transversely of the frame in parallel relation for receiving a lid between the rollers at opposite sides of the pair of bru has for supporting a lid fed between the a power drive for rotating said brushes in the direction and the upper one faster than the lower brush to cause the upper brush feed the lid relative to the lower brush with a scouring action by both brushes againstopposite of the lid, and means for saturating said brushes with water for washing the lid.
