Positioned at each end of the tube 88 are identical roller bearings 4| held in place by identical collars 48 and lubricant seals 44 pressed or otherwise secured in the said tube 88. This duplication of parts and machining operations greatly reduces the manufacturing costs in respect to the machine. Lubricant seals 44 not only prevent the escape oi lubricant but also protect bearings H from dirt and the like.
At the right end of the tubes 88 (Figure 8) are cone-shaped washers 45 pressed or otherwise secured in grooves 48 forming a V-shaped pulley designated 41 providing means for rotating the peeling rollers 34 about shaft 42. Two cylinders 34 forming a unit have pulleys 41 disposed in position shown in Figure 8, while the two cylinders making up the other unit have their pulley in the position assumed by the cone-shaped washers 45a indicated by dotted lines in Figure 8 or in the position shown in Figure 10, designated 41a.
A disc 48 (Figure 8) pressed or otherwise secured in groove 48 serves to protect the pulleys 41 and 41a from water constantly being sprayed upon the vegetables during the peeling operation. Disc 48 being thin and rotating at high speed acts as a slinger throwing off water at a tangent to its periphery.
Squared sections 58 at the right end of shaft 42 (Figure 8) are adapted to fit into the complemental square apertures 5i in the roller holder- 52 (Figures 9 and where they are secured by washers 53 and nuts 54, 55, and 58 (Figures 5, 8 and 10) The ends of shafts 42 also fit into the circular apertures 51 in the holders 52 to insure rigidity (Figure 9). The arcuate hooded section 58 (Figures 9 and 10) on the extended portion of the roller holder 52 prevents water slung from disc 48 from being thrown upwardly into the drive mechanism.
The squared sections 68 on the opposite ends of shafts 42 just described are adapted to fit in the complemental square apertures 8| in roller holder 62 (Figures 11 and 12) where they are secured by washers 83 and nuts 64. The circular ends of shafts 42 also fit in the circular apertures 85 of holders 82 providing additional rigidity.
Roller holders 82 are supported for oscillative movement upon studs 88 (Figure 3) pinned or otherwise secured in the end casting 38 and inserted in the circular aperture 68a of said holder 82 (Figure 12). Holders 52 are each supported upon a shaft 81 (Figure 5) for oscillative movement therewith, said shaft being pinned or otherwise secured in the circular aperture 88 of said holders 52.
Shaft 51 is mounted i'oroscillative movement in the lower end of support 88 (Figure 5). The uppermost portion of support 88 is bolted to the face of the T-shaped projections 18 (Figure 13) of an end casting II by bolts I2. End casting II is riveted or in some other conventional manner secured to member I88 (Figure 4).
Rigidly fixed in the cylindrical projection I4 of casting 'II (Figure 13) is a stud I8 upon which there is rotatively mounted a spur gear I5 (Figure 14) held in position upon said stud by a washer I8, pin I1 and a shoulder formed at the face of projection I4.
Journal box I8 (Figures 4 and 13) is secured to projection 14 of casting II by the arm 18. Spur gear 88, (Figure 4) has an extended solid hub (not shown) which is journalled in the box I8. V-pulley I88 is pinned or otherwise secured to the extremity of the above mentioned extended hub of gear 88.
Incorporated with the extended hub of gear I5 (Figure 14) is an eccentric 8I upon which rides the strap 82 held in position by the shoulder 88 and the plate 84 secured by bolts 85.
Integral with the eccentric strap 82 is the connecting arm 84 (Figures'4, 5 and 14) whose lower extremity is pivotally connected to the most rearwardly pair of peeling rollers by the stud-like projection 88 on the nut 54 (Figure 8) which fits in the complemental circular aperture 88a in arm Depending pivotally from the strap 82 is a connecting rod 88 (Figures 4, 5 and 14) held in position within the circular aperture '81 of said strap 82 by pin 88. The lower extremity of rod 88 is pivotally mounted in the circular aperture 88 in the nut 55 (Figure 10) which is mounted on the shaft 42 of the forwardmost pair of peeling cylinders 84 in the device. From Figure 5, it can readily be seen that the rotation of the eccentric III by the movement of gear 15 causes an oscillative movement in the two pairs of peeling cylinders 84 by means of the two connecting members 84 and 88.
A base plate 88 (Figures 2 and 4) for mounting an electric motor 8i is hinged upon the rod 82. Rod 82 is secured in circular apertures 88 in leg 2i (Figure 4) and in casting II at 84 (Figure 5) and held against longitudinal displacement by the pins 85 and 88. The motor 8I is attached to the hinge base plate 88 by the bolts 81 (Figures 1 and 2). Keyed to the motor shaft 88 (Figure 5) is a double groove V-belt pulley I21 which drives the V-belts 88 and I88, the main drive for the device.
A guard I8I (Figure 4) encloses the parts of the two V-belts 88 and I88 exposed above housing 24 as a precaution for the safety of the operator.
Although guard I8I encloses the V-belts 88 and I88, it has been hinged on rod 82 in such manner as to allow it to be swung in the clear when belts are replaced.
To compensate for any elongation of the V- belts 88 and I88, and insure proper tension in said belts an adjustment means has been provided. This adjustment means consists of a thumbscrew I82 (Figure 1) in threaded relation with a nut I83 welded or otherwise secured to the base plate 88. Manipulation of the thumbscrew I82 which bears upon shelf-like portion I84 01 the longitudinal side member 22 (Figure 5) raises or lowers the motor shaft 88 due to the hinged action of base plate 88 on rod 82, thus varying the tension in belts 88 and I88. Thumbscrew I82 may be locked in any position by means of the nut I85.
A portion of the housing 24 consists of a hopper I81 having front and back sides 22 and 28 (Figure 6) in common with the left end of the housing, and an end wall I88 (Figure 4) depending downwardly into the housing. From Figure 6 it will be seen that the lower edge of end wall member I88 contains juxtaposed arcuate indented sections I88 out upon a radius corresponding substantially to that of the arcuate sections of the roller holders 82, the faces of which are allned with and complete the end wall of hopper I81 and housing 24. Similarly, at the opposite end of hopper I81 (Figure 7) the wall member I88 contains indented arcuate sec- A spray pipe III positioned within the hopper I01 is shown in Figures 6 and 7. The pipe enters the end wall I08-through an arcuate opening and is held in position by the bolt I I2 (Figure l). The purpose of the spray pipe I I l is to supply a liquid to be sprayed over the vegetables to cleanse them while they are being peeled and to, wash the refuse toward and out a refuse spout I I3.
A cover II4 confines the spray and particles of vegetable peelings or skins within the hopper during the peeling operation. Rivets II5 (Figure 6) serve to pintle ears I35 at the back corners of the cover to the hopper end members I08 and I09.
The peeled vegetables are discharged through opening II1 (Figure 6) at the front side of the hopper I01 and guided therefrom into any suitable receptacle by the spout II8 riveted to the hopper wall about the opening. A hinged door I I9 with its lower edge adapted to fit into groove I20 may be employed for closing the opening 1 during the peeling operation. Slots I2I in ear-like extensions I22 of the door H9 and through which a rod I23 passes coact with such rod to form a hinged mounting for the door. Rod I23 is suitably secured to the upper end of side members of spout H8. A handle I24 riveted to door I I9 provides for easy manipulation thereof. A groove or trench I25 positioned laterally at the end of the spout II8 collects any liquid that might escape while the vegetables are being discharged. Liquid collected in said groove is returned to the bottom of housing 24 to be discharged through spout II3 by means of duct I26.
Nut I 21 containing a circular aperture I28 and in threaded relation with the inner walls of the duct I26 serves to make a liquidtight joint between duct I28 and longitudinal side member 22.
The bottom of housing 24 forms a drain indicated generally by the reference character I28. Substantially all of the refuse which contains waste water and particles of peeling is conducted away through the drain I I3.
Although gear 15 and the eccentric mechanism must be withdrawn before v-belts 89 and I00 can be replaced, the replacement of said belts is a simple procedure since only pin 11 (Figure 14) needs to be extracted and then the said gear and eccentric mechanism may be removed from stud 13 as a unit.
The same procedure is followed when it is desired to remove the peeling cylinder units except that the bolts 12 (Figure 5) securing the supports 69 are also removed permitting the rollers to be withdrawn from the device in a longitudinal direction.
- Door I28 (Figures 2 and 4) at the right end of the device disposed in grooves I29 and I30 of straps 25 and 26, provides accessibility to the drive mechanism. An upward movement of door I28 releases it and permits withdrawal from the grooves. Handle I3I has been riveted to door I28 to facilitate its manipulation.
Motor 9|, by means of pulley I21 (Figure 5) and V belt I00 drives pulleys 41 thereby rotating the forward pair of cylinders 34. Disposed in another groove in pulley I21 is belt 88 which acts upon pulleys 41a imparting rotative movement in the rearward pair of cylinders 34. Belt 99 also drives pulley I06 which in turn drives spur gear in meshing relation with gear 15. Gear 15 actuates eccentric 8|, thus causing the two connecting members 84 and. 86 attached to eccentric strap 82 to oscillate the two pair of cylinders 34. The oscillating or rocking movement of the cylinders is about stud 66 (Figure 3) at one end of the A device, and in the lower extremity of support 69 (Figure 5) at the drive end of the cylinder.
The rocking or oscillating movement of the cylinder which takes place at the time of their rotation constantly changes the contour of the supporting surface of the bed of cylinders, thus permitting all sides of vegetables or other articles supported thereon for peeling to havetheir peel or skin come in contact therewith. All cylinders 34 rotate in the same direction.
Such rotative movement together with the oscillating or rocking motion of the cylinders causes the whole mass of vegetables in hopper I01 to revolve slowly in a unitary mass, thus allowing each individual vegetable to come in contact with each cylinder 34. After each individual vegetable comes in contact with the last or most rearward cylinder, having traversed the others in turn while progressing rearward at the bottom of the unitary mass, such vegetable is carried upwardly to the top of the mass and progresses forwardly along the top of the mass until it again progresses downwardly to the bottom of the mass to be again conducted over the cylinders. This process is repeated until all of the articles are peeled. The rocking movement of the cylinders 34 more thoroughly agitates the vegetables and thus facilitates more rapid peeling. The constant turbulation of the articles by the upward and downward movement of the cylinders overcomes any ten'dency of the vegetables to pack into a relatively stationary group.
Upon completion of the peeling process, door H8 is opened and the vegetables are released through opening H1 in the side of the hopper,
and are guided by chute II8 into a suitable receptacle.
