1 Claim.
Our invention refers to cleaning and polishing machines for household tableware, such as knives, forks, spoons, and the like.
The object of our invention is to provide a simple and effective motor driven polishing machine, whereby tableware may be quickly and efiectively polished.
The invention primarily embodies a housed electric motor, carrying a disc, jacketed with a removable burnishing or polishin cloth and in addition thereto, a removable oval polishing unit for treatment of concave, oval, or curved articles; or ther shapes.
With the above and other objects in View, which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of parts, substantially as hereinafter described, and more particularly defined by the appended claim, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim.
In the accompanying drawings is illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.
In the drawings:
Fig. 1 represents a sectional elevation of a polishing machine embodying the features of our invention, the section being indicated by line II of Figure 2.
Fig. 2 is a plan view of the same.
Referring by characters to the drawings, I indicates a domed base having a bottom open mouth.
The crown of the base is apertured and provided with an anti-friction bearing 2.
The bearing has extended upwardly therethrough a shaft 3 of an electric motor 4, having a flange bottom secured to the base mouth by a screw 4', the said motor flange serving as a closure for the dome or base bracket.
The end of the shaft 3, which projects through the bearing 2, is formed with a threaded socket 5, and secured to said shaft end is a disc 6. The periphery of the disc is stepped downwardly in an offset and terminates in a peripheral flange 6.
The fiat upper face of the disc has fitted thereto a burnishing cloth I, the outer edge of which conforms to the off-set flanged portion of the disc and is secured thereto by a ring 8, Thus the ring forms a frictional clamping member for the cloth and it is secured to the disc flange by screws 8. Hence, the cloth may readily be renewed and the burnishing nature of the cloth may be varied indefinitely.
The burnishing cloth is provided with a center aperture through which the threaded shank 9 of an oval burnishing unit It], is fitted and secured in the socket 5.
The current to the motor is controlled by a switch I l, and also a speed control.
In the operation of the polisher or burnisher, it is obvious, as for example, when it is desired to polish knife blades, the knife, as indicated in dotted lines, Figure l, is pressed flatly upon the cloth whereby said knife blade is properly burnished on either side.
It is understood in polishing all flat household utensils, the oval polishing unit may be removed whereby the entire face of the disc is clear for use.
When it is desired to polish spoons or the like,
as indicated in dotted lines, Figure 1, the bowl of the spoon will snugly fit the oval polishing surface of the unit it), which unit for this particular purpose is inserted into the motor shaft socket.
It is also understood that various curved surfaces of household utensils may be similarly treated by applying said surfaces to th oval unit. It is also apparent that the domed housing is closed and encases the motor unit to guard the same against damage from moisture and the like.
We claim:
A polishing machine of the character described, comprising a domed open bottom base, an electric motor encased therein having a flange secured to the open bottom of the base, a motor shaft extending through the upper crowned portion of said base, the shaft being provided with a threaded socket at its ends, a disc secured to the shaft having a step edge, terminating with a flange below the disc face, a polishing cloth fitted to the face of the disc, having its edge stepped downwardly and engaging the disc flange, a ring fitted to the edge of the cloth disposed below the disc surface, means for securing the ring to said disc flange, and an oval polishing unit having a threaded shank in engagement with the shaft socket.
