- 5 the Weightofthe abradi-ng disk and-its goperating shaft, whereby; they are capable of rotating at high speech-the, lower end ofthe shaft 'bei'ngsteadie'd in a. bearingto prevent lateral swinging.
20 Further: objects of myinvention-comprise the locating. of the abrading orxparingmech- 'anism at a. relatively low; elevation whereby low' vibration is assured, and. easy access in charging and discharging may be had, While the'motorgan-d driving'means are arranged at a higher and rear position so as to'form no bs truction and permit free access to. the operative or Working part-s; andalso in providing an organized machine in which Water :30 may be freely used during its operation'without 'danger to the driving or motivepower.
hly object is also to provide a light running machine in'thatthe rotating abrading disk and shaft therefor are suspended on ball 5 bearings and in a manner that the bearings are protected "from objectionable contact with Water.
With the above and. other objects in View, the nature of'vvhich Will be more fully under- 4 stoo dfromthe descriptionhereinafter, the
invent-ion consists in the novel construction of vegetable paring machine, as -hereinafter more fully described and defined in the claims.
45 Referring to the drawings Fig. 1 is afront elevation of my improved paring machine Fig. 2 is-a sect-ional planview taken on line 2-2 of Fig. 4 Fig. 3- is a plan view of:the machine; FigAL-is-a vertical section'ta-ken on line 4-4 of Fig. 3; Fig. '5 is a vertical section of the lowerbearing for the operative shaft of-the' abrading disk; andj Figt is a vertical section corresponding toEFig. 5 but showing a modified construct-ionthereof.
2 is apedestal or floor baseandupon-it is "securedthe central hub 3 madelintegralvvith a circular inclinecbfioor 5 whichis bounded by acimular flange 4. Immediately above the'floor 5 and hub 3 is a'step bearing depening upwardly forreceiving andsteadying the lower end. of the vertical shaft 2'8 to 'WlllCll the abrading disk 26 is secured. -T-he' inclined floor 5=has at'itspovverportion-a drainage aperture-7 through which all surplus-water may freely escape.
"The body or bowl His formed of Tfou-r curvedsections- 8 which, When-placed edge to e'd-ge, f0rm a-circular or cylindricalchamber which "fits down uponthe' upper edge of the circular flange-4 of: the hubhndfioor portion above referred to. These sections Soverlap as-at- 9' (Fig. 2)' and are secured together by screws 150. The lowerportions: 8 "of the sections 8 are-sleeved down into the circular flange 4" (Fig. *4) and moreover; are secured in place thereon ;-by'=-bolts 12 extending through lugs 11 (Figs'l and 2'). "The rear section i8 1 is formed With an "inwardly eX- tending perforated avail to {form a spray chamber from -W-l1-ich --water freely passes through the aperture and into'th efbowl 14L Whiohcontain-s the potatoes to be pared. The diagrammatically opposite section B is formed. With a discharging aperture 15 provided-With. a threshold 17 having inward drainage aperture 18 to permit excess water running back into the space above "the floor Sand under the rotating abrading'di'sk 26 (Fig.1). Azspout 19 extends 'forvvard from'about the bottom and sides of the discharge opening 15 and constitutes a discharge chute. A door 15 hinged at 16 to the upper part of the section 8 provide-s a closure for the opening 15 and may be held in closed position by the handle 20 pivoted to the door at 21 and adapted to engage a lug 22 on the threshold portion. By opening the door 15 when the disk 26 is being rotated, the pared content will, under centrifugal action, be discharged.
The upper part of the body or bowl 14 is provided with a cover 23 which is flanged and fits to the sections 8 as shown in Fig. 4. This cover is provided with a feeding aperture 24 having grooved side walls and in which a closure 25 is freely movable in a horizontal lane. When the slidable closure 25 is moved in a circular direction, it provides an elliptical opening 24 (Fig. 2) at the front por-.
tion of the machine and through which the charge of potatoes or other vegetables may be introduced. The closure 25 is so shaped that in effect itis hinged adjacent to the shaft 28 and center of the cover 23 and with its outer curved edge guided in the curved groove 24 (Figs. 2 and 4 The interior walls of the sections 8 are formed with abrading material such as corundumsprinkled in the molds in which. the sections 8 are cast so as to become attached to the iron. The abrading surface may be of any other suitable substance and attached in any other manner, as I do not limit myself in this respect. The rotatable abrading disk .26 is made of more or less dish-shape and with its upper surface 27 similarly provided with corundum or other abrading material, as in the case of the body sections 8. The disk 26 may be of uniform concavity as in Fig. 4, or provided with irregular raised portions 26 of any desired shape as preferred.
The shaft 28 is centered at its lower end in the step bearing 6 to prevent lateral displacement and extends upwardly through the cover 23 and journaled in a bearing 33 on a frame 34 which is hinged at 35 to the upper ends of two frames 36 secured at their lower ends to the flange 4 at the rear part of the machine. This frame 34 is provided with lateral arms 34 (Fig. 1) which rest upon the upper ends of the side brackets 42 which also are firmly bolted to the flange 4 at 44 and may also be detachably bolted to said brackets by bolts 43. In thismanner, the frame 34 is firmly positioned during the operation of the machine, but by removing the bolts 43 it may be swung upward for reasons now to be described.
When the shaft 28 is in operative position (Fig. 4), it is secured at the top to a bevel gear 37 between which and the top of the bearing 33 is interposed ball or roller bearings 38 so that the shaft may be freely rotated notwithstanding the weight of the parts. A collar 39 may be secured to the shaft 28 by a set screw below the bearing 33 to prevent the shaft and gear lifting. An electric motor 40 is bolted to the frame 34 above the hinged portions 35 and is provided with a small bevel gear 41 which meshes with the large gear 37 (Fig. 4) and by which it is driven.
The motor 40 is enclosed within a casing 48 also secured to the frame 34 and this casing may extend laterally in a fixed portion 45 and in a hinged portion 46. These portions 45 and 46 form a box enclosing the gears 37 and 41 andalso the ball bearing 38. When it is desired to oil the gears or bearings, the case part '46 is lifted upward and swung about its hinges 47. It will be understood that in this manner the motor and driving mechanism are protected against injury from moisture.
The manner in which the disk 26 is suspended upon the shaft 28 is best shown in vvFigs. 4 and 5, from which it will be seen that the disk is provided on its under side with a hub 29 through which the shaft extends. This hub has upwardly extending side notches or. recesses 31 which receive the ends of a transverse pin 30 which extends through the shaft. In this manner, the disk is made to rotate with the shaft but by raising the disk, the pin 30 may be removed and the shaft withdrawn from the, disk. When this is being done, both the shaft and disk are raised part way up throughthe body or bowl 14 so as to permit access below the disk. To permit the raising of the shaft 28, the collar 39 must be loosened, the case part'46 raised and the gear 37 and shaft 28 lifted. In this waythe shaft may be lifted entirely clear of the machine. The disk 26 may be sustained wholly by the shaft 28 and its ball bearings 38 or, if desired, the hub 29 of the disk may lightly rest on the hub portion of the step bearings 6. It is desirable, however, to rely on the ball bearings as the sustaining means so that the machine may be run with the least power. Vhen the shaft 28 is removed, the frame 34 may be swung upward and back, the cover 23 removed and the disk lifted out In assembling, the reverse order is employed.
The water is supplied to the machine in the following manner. A pipe 51 connected through a union 52 with a plate which seals the spray chamber 4-9 and by which water is sprayed upon the materials within the bowl 14. A branch pipe 54 delivers water to a horizontal nozzle pipe 55 terminating in a curved spraypipe 56 arranged in the space below the disk and above the floor 5 which insures thorough washing of waste matter including the peelings from the machine through'the waste pipe 7.
The hub 29 of the disk 26 may have an annular apron 32 about it to shield the bearing 6 from p'eelings and excess moisture. In Fig.
6, I haveqshownia:modified constructionifor supporting the "disk-26 upon the shaft 28. In .this construetion :there is provided: a collar "29 secured'to' the shaft bya set screw 30. [l -his collarisprovided on the lower part with the apron and-at the upper part with lugs 30 -.corresponding to 'the endsof the pinRO in 5. This: construction obviates the neeessit-y of reinovingzthe pin 30.
It will now be apparent thatI have devised a novel and useful cohstruction which embodies the features of advantage enumerated as desirable, and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that I do not restrict myself to the details, as the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention.
