showing the manner of removably securin the grater to the disk. Fig. 8 is a detail o the clip for securing the grater to the disk. Fig. 9 is a section of part of one of the graters, enlarged, and morel clearly illustrating the formation of the burs thereon. Fig. 10 is a detail perspective view of the grater for the inner concave wall of the casing. Fig. 11 is a detail perspective view of the door. Fig. 12 is a detail perspective view of one of the cleats for holding the door andgrater in position. Fi 13 is a detail perspective view of a cleat o modied construction. Fig. 14 is a detail perspective view. of the lug for holding the nozzle -on the u ward extension of the hub of the As illustrated, and as I prefer to embody my invention, the casing 1 is of cylindrical formation having its convex wall formed of a sheet 2, supported at its upper and lower edges, respectively, by hoops 3 and 4, and has `a conical bottom 5 converging to a tubular support 6,to which said bottom is ri 'dly secured with its joint therewith ren ered water tight. At one Side of .the casing an opening is provided in the convex wall thereof to forman outlet 7 which is provided1with'a`spout k8 of suitable formation secured to the hoops 3 and 4 and to the sheet 2 of the casing. As shown, the hoo 3 con tinues around. over' the outlet 7 an behind this hoop v3 adoor'9 is mounted to slide vertically upward to open the outlet or downward to -close it. This dooris supported at the sides by. cleats 1Q, which are secured to the inner concave-wallet the ycasing and have lips-11 'takingo'ver the parts ofthe door 9 -near its Avertical edges. This door 9 .is .provided with a flange l2 to affords. handle for operating the door. The lO also have lips 13 4on their'other sides, and a removable. grater-14 is adaptedto' t closely against the inner'concave wal-l of* l e casingl therearonnd with its ends under these lips 13 of the cleats 10. This grater 14 consists in a long sheet provided with a series of burs 1 5 formed by perforating it in the well known manner o constructing graters from metal sheets, as is best shown 1n Fig. 9 of the drawings. This sheet is slid into the casing vertically from the top with its burs 15 presented inwardly of the casing, being,r just long enough to spring closely against the Wall of the casing when its ends are held under the lips 13 of the cleats 10. The door 9 is provided witha grater 14 having similar burs 15, this grater being permanently secured to the door and terminates close to the lips 11 on the cleats 10 which overlap the door. It will thus be seen that the grater 14 may be most conveniently withdrawn and inserted, thereby allowing the adjacent parts of the grater and the wall of the casing to be cleaned and dried thoroughly, and allowing the grater, when it is worn out, to be replaced conveniently.
The cover 16 is frusto-conical in shape and ts into the top of the casing after the manner of sheet metal lids, its smaller end 17 being up, and this end being open to conveniently admit the vegetables to be peeled. The adjacent part of this cover 16, preferably, is cut away to it around the vertically slidable door 9, and permit the free operation of the door when the cover 16 is in place on the casing.
The tubular support 6 extends above its juncture with the conical bottom 5 of the casing to about the height of the lower part of the hoop 4 of the casing, and is provlded with a series of openings 18 in its wall adjacent to its juncture with the bottom 5, these openings being so located and arranged that water, carrying refuse from the vegetables, will readily pass from the bottom 5 of the casing through these openings 18 into the interior of the tubular support 6. The lower' end of this tubular support 6 is rigidly secured to a suitable base 19 for the machine, conical -in general formationz with its smaller end up. Rigidly secured 1n the lower end of the tubular support 6, is a conical or funnel shaped coupling 20 with its large end up and having a waste pipe 21 fitting into its lower smaller end. At one side of this waste pipe 21 the supply pipe 22 passes throughV the funnel shaped coupling 20, having a water tight joint therewith at 23, and thls supply pipe 22 passes upwardly and is deflected at 24 interiorly of the tubular support 6 so that it is'brought into the center of said support. The up r end 'of this supply pipe 22 fits into a headp25 which has arms 26 extending radially therefrom in a horizontal direction, driven into the interior of the upper end of the tubular support 6. This head extends above the upper end of the tubular support 6, and is reduced so that it has a spindle 27 and a shoulder 28 at the beginning of said spindle.
An opening 29 extends entirely through the head and its reduced part which forms the s indle 27, communicating with the inlet pipe 22 at its lower end and forming an outlet at its upper end. The disk 3() rotates on the spindle 27 in a horizontal plane, having a hub 31 extending above and below the disk and having radial ribs 32. This disk is provided with a heavy rim 30', and on the periphery of this rim a series of teeth 33 are provided extending radially. Thus, the disk constitutes both a 'Hy-wheel and a spur gear. A pinion 34 meshes with the teeth 33 of the disk at one side of the casing, preferably at the side opposite to that on which the outlet 7 is provided, this pinion having a shaft 35 which extends vertically through the conical bottom of the casing at which point it is provided with a suitable gasket 36 to form a water tight joint between the shaft and the bottom of the casing. As shown, this shaft 35 forms part of an electric motor 37 which is mounted on a plate 38. However, it will be understood that any other suitable motor or driving mechanism may be provided for the machine and supported on this plate 38. For supporting the late 38, a/clamp 39 takes around the tubu ar' support 6 at any bottom 5 of the casing an the base 19, and has an arm 40 on which the plate 38 may be bolted. By having the clamp 39 thus adapted for adjustment vertically of the tubular support 6, the proper relative ad- `ustment o the pinion 34 and disk 30 may e provided and maintained with great convenlence, the clamp 39 being thoroughly rigid after the bolt 41, taking through its jaws, is tightened.
The hub 31 of the disk 30, where it extends above the disk, receives the nozzle 42 in the form of a tube with its upper end closed and its lower end open, this open lower end fitting over the spindle 27 where it extends above the hub 31. This nozzle 42 is provided, near its u per closed end, with perforations 43 aroun it in its convex wall, these perforations being, preferably, provided 1n two series, the upper of which extend radiall in a horizontal direction and the lower o which are inclined downward. For conveniently detachably securing this nozzle`42 on the upward extension 4of the hub 31 the lower end ofthe nozzle is provided with a slot 44 which extends upwardly parallel to the axis of the nozzle and then circumferentially thereof a short distance. The upward extension of the hub 31 is provided with a lug 45 extending vertically and then radially inwardly of the hub to take throu h the crcumferentially extending part of e slot 44 when the lower oint between the cnd'ofthe nozzle rests against the top of the upper extension 'of the hub. Thus, in putting the nozzle in place it is only necessary to push it down onto the spindle 27, allowing the lug to enter the vertical part of the slot 44, and then turn the nozzle so that the hub 31 and adapted to lie flat on the flat.
upper surface ofthe disk. This grater has burs 15, like those on the grater 14 around the concave wall of the casing, and is secured to the disk 30 by means of clips 48 consisting in wires each with a horizontal' part joining two Vertical parts, the vertical parts being inserted downward through twoopenings 49 in the grater and through two openings 50 in the disk, the lower ends of the clips. being bent under the lower suriace of the disk. These clips may be of soft material so that they are conveniently bent and unbentto allow the grater to be placed in position or removed for cleaning and drying the adjacent surfaces of the grater and the disk. Preferably, the grater 46 has to extend down over the periphdry ofthe disk do. The disk 3o is provided with a series of perforations 51 which allow drainage of water from under the grater. The disk 30 and its grater 46 are of somewhat less diameter than the interior diameter'of the casing 1 so that an annular space 52 is left therea'round adjacent to the wall of thefcasing. The parts are so proportioned that the concave grater'illon the wall of the casing terminates substantially level with the upper surface of the circular grater 46 on the disk.
Thus constructed, Vegetables, such as 0- tatoes, or fruits of a similar nature, having skins to be removed, may be thrown into the casing through the open top 17 of the cover 16 onto the grater 46 on the disk 30,
which is rotated, 'and the vegetables. will be thrown outward by centrifugal` force against vthe concave grater 14l on the wall of the casing and will rebound repeatedly with the result that after the operation of the machine for a short time the skins of the vegetables will be entirely removed by the continual abrasion of the burs 15 lof the` graters. Water being' admitted through` the inlet pipe 22 4and throu' h the" o ening 29,
in the head 257and its 'spindle 2 into the nozzle 42,] this Vf water will escape through the'openings 48 in the nozzle and when un-` .operated upon.
of openings 43 in the nozzle 42. The streams from the upper series of o enings will be directed in a horizontal ireetion, while those from the lower series will be directed downwardly. The result of such an arrangement of the streams of water from the nozzle, is that the horizontal streams strike the conca-ve ater 14 near itsupper termination, whi e the downwardly inclined streams strike it near its'lower terminat-ion. These rotating streams thus strikin the stationary concave grater 14 are de ected backward onto the circular g'rater 46 and the particles of each streamjstriking with the particles of the other, dueto the rotation of the nozzle, so distributes the water/ that bothv of the graters are continually washed in the most effective manner during the operation of the machine upon the vegetables. The skins of the vegetables, removed by the graters in small particles, are thus washed down from the concave grater 14 and o from the horizontal circular grater 46 through the annular space 52 around the disk 30 and down along the bottom 5 of the casing through the openings 18 into the tubular support 6, and from there into'the waste pipe 21 which may be connected with anygsuitable means for disposin of the refuse.
he supply pipe 22 may be connected with suitable supply of water under pressure and may be provided with any desired means for controlling the flow of the water,which need not be herein shown or described.
The cover 16 of frusto-conical formation, as hereinbefore described, extending over the parts of the casing near' its convex wall, prevents the splashing of the water out .of the casing durlng the operation of the machine, but at the same time is always open for the ready insertion of the vegetables to be When the vegetables have been `operated upon for a sufclent length of time, as may be readily noted by lnspec'- tion through theopen top .17 of the cover of 'this casing, it isuonly necessary to slide the door 9 upward, opening the-outlet 7 while a suitable receptacle is held under the spout 8, leaving the disk to rotate at full speed, upon wh1ch the vegetables will be thrown out through the spout into the receptacle by Aa -gapin it adjacent to the` inion, which `is closed by a bulging late 4 secured to the ends of the hoop at t e gap and holding the hoop-to ether around the casing. As illus-v trated, t is plate may have, formed integral with it, part of the water tight joint aroundv the shaft 35, where it extends through the bottom of the casing and is provided with the gasket 36, as hereinbefore mentioned.
As illustrated in Fig.`5 of the drawings, instead of providingthe disk 30 with the radially extending teeth 33, it may have downwardly facino' teeth 33 in such form that the disk constltutes a bevel gear, and a bevel pinion 34 may be mounted on a horizontal shaft 35', this bevel pinion meshing with the teeth 33 of the disk. This shaft passes through the lower hoop 4 of the casing and has a Water tight joint formed therewith by means of the gasket 36. A suitable bearing 53 is provided for the shaft outside the casing, mounted on a plate 38 of an arm 40 which may be secured to the tubular support of the casing by means of a clamp similar to the clamp 39, as hereinbefore set forth. The shaft 35 may be the shaft of a suitable motor, or it may be otherwise suitably rotated.
Another modification of the driving mechanism consists in providing the periphery of the disk 3() with a series of teeth 33 in such form that the disk constitutes a worm gea-r, and providing a worm 34, which meshes with the teeth 33 of the' disk and is mounted on a shaft 35 extending tangentially through the wall of the casing and being part of a suitable motor 37. This motor is mounted on a plate 38 of an arm 40 supported like the arm 40. Here the hoop 4 of the casing is provided with a gap closed by a bulging plate 4 to accommodate the Worm 34 and provide a bearing for the shaft 35 where it passes tangentially through the Wall of the casing in such form that a suitable gasket 36 may be provided around the shaftat this point to make a water tight joint.
It will be noted that with either the spur gear and pinion or the bevel gear and pinion considerable speed reduction from the motor to the disk may be attained, allowing the use of a small motor running at a high speed, which is conducive to economy in the first cost of the motor, as well as in the maintenance of the device. I With the use of the Worm gearin it will, of course, be understood that this speed reduction may be further increased with correspondingly increased advantages. In any instance, the disk, when provided with the rim 30', will rotate steadily and insure smooth and even operative engagement of the gear teeth meshing at its periphery. Thus, this disk, performing its primary function of carrying the grater 46,l constitutes part of the simple driving mechanism comprised by it andthe pinion in mesh With'its teeth and also the vfly-wheel of the machine, all of which is entirely inclosed in the cylindrical Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:
