GEORGE S. BLAKESLEE, OF CHICAGO, ILLINOIS.

POTATO-FEELING- MACHINE.

To all whom it may concern:

Be it known that I, GEORGE S. BLAKESLEE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Potato-Peeling Machines, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to potato peeling machines of the type in which the peeling is removed by agitating the potatoes in contact withan abrasive surface, and has for its object to provide certain improvements in the machine illustrated and described in my pending application Serial No. 5:39AM, filed January 20, 1910, in which the receptacle and the rotary bottom on which the potatoes or other articles to be operated upon rest are composed throughout of abrasive material, such improvements relating particularly to the construction of the bottom as hereinafter set forth. I accomplish this object as illustrated in the drawings and as hereinafter set forth,

What I regard as new is set forth in the claims.

In the accompanying drawings,Figure l is a front elevation of my improved machine; Fig. 2 is a vertical section on line 22 of Fig. 1; Fig. 3 is a plan view of the bottom-plate; Fig. 4 is an under side view thereof; and Fig. 5 is an edge view thereof.

My improved machine comprises a stationary receptacle cylindrical in form and having an aperture at the top for the admission of the potatoes or other articles to be operated upon. Said receptacle also is provided with a bottom formed integral with the sides and having a spout or discharge opening for the escape of water and parings,the receptacle being mounted on a suitable stand or pedestal which carries mechanism for rotating the bottom-plate, the latter being mounted in the lower portion of the rece tacle upon the upper end of a vertical sha driven either by hand or power through the driving mechanism above referred to. Both the receptacle and the ro- Specification of Letters Patent.

Application filed September 25, 1911.

Patented Oct. 1, 1912. Serial No. 651,102.

tary bottom-plate are formed throughout of an abrasive substance composed of comminuted flint, or other suitable material, bonded together by cement or its equivalent substance that is of a lower degree of hardness than the flint. so that in use the bonding material disintegrates more rapidly than the abrasive substance proper and consequently the abrading surface is always sharp and effective. By this construction the machine is made practically indestructible and cannot wear out since the walls of the receptacle and the bottom-plate are made of such thickness that it is practically impossible to wear them out. 7

In my present invention a bottom-plate of improved construction is provided to assist in moving the potatoes or other articles out toward the inner wall of the receptacle so as to bring them more efiectively into contact therewith, and also to cause the articles operated upon to roll over and thereby insure their being peeled completely. This is accomplished by making the bottom-plate conical in form through the greater portionof its area, the upper surface sloping downward to a point near the margin, which is comparatively fiat. Small recesses or cups are provided, preferably at diametrically opposite points adjacent to the margin, which, in the rotation of the bottom-plate, has the effect of causing the potatoes to roll more or less and thereby insure the proper peeling thereof.-

Referring to the drawings for a description of the embodiment of my invention therein shown,6 indicates the cylindrical receptacle in which the potatoes or other articles are placed, said receptacle having an integral bottom 7 provided with a spout or outlet 8, as shown in Fig. 2. The receptacle 6, including the bottom 7, are made integral and are composed of comminuted flint or other suitable hard substance mixed with cement or other suitable bonding material.

9 indicate'san additional outlet adjacent to the bottom 7, the upper surface of said bottom being inclined in opposite directions toward the outlets 89 for the discharge of water and peelings.

10 indicates a door provided at one side of the receptacle 6 and also formed of the same material.

11 indicates standards or legs which support the receptacle 6.

12 indicates the inlet opening at the top of the receptacle. The legs 11 are preferably made adjustable vertically so as to provide for regulating'the height of the receptacle 6 to any desired extent.

13 indicates cross-braces connected with the several legs and forming supports for the driving mechanism.

14 indicates a vertical shaft mounted in suitable bearings on the braces 13 and eX- t-ending up through a bearing 15 in the bottom 7. The shaft 14 is provided with a beveled pinion 16 which meshes with a bevel d pinion 17 carried by a shaft 18 and provided with ahand-wheel 19, or other suitable means for rotating the same, as shown in Figs. 1 and 2.

20 indicates a water-pipe communicating with the upper portion of the receptacle.

21 indicates the rotary bottom-plate, which is composed of the same material as the receptacle 6 and is mounted upon the upper end of the shaft 14 and connected to it so as to rotate therewith. As shown in Figs. 2, 3 and 5, the upper surface of the bottomplate is made convex or conical, sloping downward toward the margin thereof.

22 indicates recesses or cups in the bottomplate 21 adjacent to its margin, said recesses being large enough to receive a potato, apple, or other similar article. The marginal portion of the bottom-plate be tween the recesses 22 is substantially flat, as shown at 23, in Fig. 3.

24 indicates a handle for lifting the bottom-plate out of the receptacle when desired,

as for cleansing purposes.

When the potatoes or other articles are placed in the receptacle they rest upon the bottom-plate 21. By rotating the latter the potatoes are caused to roll more or less upon the bottom and are also carried around in contact with the inner wall of the receptacle so that by the action of the abrasive surfaces they are effectively pared, the parings, and water which is supplied during the operation, esca ing through the outlets 89.

That w ich I claim as my invention, and desire to secure by Letters Patent, is,-

1. A peeling machine, comprising a suitable receptacle having an abrasive inner wall and a rotary bottom-plate therein composed throughout of abrasive material and asuitable bonding substance, said bottom-plate having one or more cups or recesses formed in the upper surface thereof, and means whereby said bottom-plate may be rotated.
