2,706,301 BRUSHING, CLEANING, AND SCRAPING MACHINES Philip A. Gango, Farmington, W. Va. Application October 24, 1949, Serial No. 123,119 3 Claims. (Cl. 15-23) This invention relates to improvements in cleaning, abrading and/or scraping machines, particularly well adapted for cleaning butcher blocks, etc.

The primary object of this invention is the provision of a very compact, durable and efficient cleaning and scraping machine having an improved brush head mounting means.

A further object of this invention is the provision of improved means for maintaining scraper or brush blades in detachable relation within a brush head.

Other objects and advantages of the invention will appear in the following detailed description.

In the accompanying drawings, forming a part of this specification and wherein similar reference characters designate corresponding parts thruout the several views-- Figure 1 is a side elevation of the improved cleaning machine.

Figure 2 is an end elevation of the improved cleaning machine.

Figure 3 is a bottom plan view of the improved brush head mounting structure.

Figure 4 is a cross sectional view taken substantially on the line 44 of Figure 3, showing the brush or cleaning head details and drive gearing connected to the same.

Figures 5 and 6 are cross sectional views taken substantially on the respective lines 5-5 and 6-6 shown in Figure 4 of the drawings.

In the drawings, wherein for the purpose of illustration are shown preferred and modified forms of the invention, the letter A may generally designate the im- It includes a casing structure B; motor C associated therewith, and a rotary cleaning or brush head E which may be used selectively therewith", said brush head being driven by means F connected to the motor C.

The casing structure B is preferably of cast aluminum or other suitable material, including a top wall 10, end walls 11 and 12, and side walls 13 and 14. These walls may be cast integral and the compartment 15 formed thereby is open at the bottom of the casing.

The motor C may be of any approved type, and in this connection it will be noted that its mounting is on the top wall 10, as shown in my assigned U. S. Patent 1,702,007. The motor may be mounted upon an insulating pad on top of the wall 10, by any suitable means (not shown). The motor C includes a shaft 21 extending into a gear box 22 housing the means F.

The brush head E is mounted upon a horizontal axis within the compartment 15, with bearings upon the end walls so that the brushes or scraper elements thereof project slightly below the compartment. The depth of brushing or scraping is regulated by depth regulating members 25 and 26, best shown, as to structure and mounting, in Figures 1 and 2, for vertical adjustment upon the side walls 13 and 14.

The depth regulating members 25 and 26 are preferably of the same material as the casing structure. I prefer aluminum and each includes a body portion 27 overlying the outer surface of the side wall and at the bottom thereof it is flanged inwardly at 28 to define a groove which receives the lower marginal portions of the side walls and presents downwardly facing convex surface 29 which at times may engage the butcher block or the surfaces to be scraped or cleaned; the convex surfacing preventing injury thereto. The body portion 27 of each guide member is provided at its ends with upstanding attaching portions 31 slotted at 32 to receive clamping screws 33 attached to the side walls, as shown. The slots 32 are vertical and enable the members 25 and 26 to be vertically regulated upon the side walls of the casing structure for the purpose of limiting the cleaning depth of the brush head.

Referring to the means F for driving the brush head, the same includes a pinion 40 keyed upon the shaft 21 of the motor C and meshing with an idler gear 41 mounted upon a shaft 42 which in turn is secured upon the mounting wall 43. The gear 41 meshes with another gear 45 keyed upon a shaft 46 which bears within a bushing 47 mounted upon the end wall 12 of the casing B.

The gearing is enclosed in gear box 22 which includes the mounting wall 43 and a cover 50, both of which are bolted as at 51 to the end wall 12. Bushing 47 in which the shaft 46 bears is mounted not only upon the end wall 12 but also upon the gear box wall 43, as shown in Figure 4. The shaft 46 extends into the compartment 15 of the casing structure where it is intended to be secured to the brush head.

The wall 11 of the casing is provided with a bushing 70 apertured at 71 to receive a detachable endwise removable shaft 105. At its opposite end the shaft has a bearing extension received in the opening of a discshaped member 78. The disc 78 receives the end of the gear shaft 46 therein and is keyed thereto by a bolt or set screw 80.

The brush E furthermore includes a tubular frame or body portion which receives the shaft 105 therethru. The tubular body 110 at the ends thereof has annular flanges 111 and 112. The tubular body 110 between the flanges 111 and 112 may be provided with other blades or brush stabilizing flanges 114 and 115. These flanges are all radially slotted to receive the

blades

116 and 117. The blade 116 differs only from the blade 117 in that the latter is provided with a straight scraping edge and the edge of the blade 116 may be saw toothed, or brush tufts 101 substituted, as shown in Figure 2. The

blades

116 and 117 at the ends thereof are reduced for fitting in the radial slots of the flanges 111 and 112 wherein they are secured by

detachable rings

120 and 121. The former is secured at 122 against accidental detachment and the latter at 123, both by means of bolt structures.

The brush head E may be keyed to the disc 78 by means of an L-shaped portion extending from and rigid with the ring 121, shown in Figure 3, an extension portion of which fits within a suitable slot 131 disposed across the outer periphery of the disc 78 as shown in Figure 12, and a right angled portion which engages the outer side of the disc 78*.

The machine is provided with U-shaped handle structures and 141 detachably mounted at 142 upon the side walls and extending beyond the end walls for hand engagement; the extreme ends thereof being provided with curled hand engaging portions 143.

It is believed the operation of the brush will be apparent from the foregoing. The vertically adjustable side wall members 25 and 26 regulate the scraping and brushing depth, as is apparent, and the brush heads, as well as the individual blade members or brush members thereof, may be readily detached. All of the parts may be disassembled for ready cleaning, as will be quite apparent from the foregoing.

Various changes in the shape, size and arrangement of parts may be made to the form of the invention herein shown and described without departing from the spirit of the invention or the scope of the following claims.

I claim:

1. In a machine for cleaning butcher blocks the combination of a frame structure including spaced mounting walls, a shaft directly rotatably mounted at one of its ends upon one of said walls for endwise removal from the frame structure and having the other end terminating just short of the opposite wall, a drive shaft rotatably mounted upon said opposite wall in axial alignment with the first mentioned shaft and projecting adjacent to said first mentioned shaft, means on the casing for rotating said drive shaft, a disc having an axial passageway receiving in bearing relation therein the adjacent end of the first mentioned shaft and the drive shaft, a single set screw threaded in said disc and releasably keying said disc to the drive shaft, a cylindrical type of brush head having a longitudinal axial passageway therethrough wherein the first mentioned shaft is freely received without direct keying, said disc having a transverse slot therein, and a lateral extension mounted upon the brush head having a portion removably keyed in said slot of the disc.
