HENRY W. CROWELL, OF GLEN RIDGE, NEW JERSEY.
MACHINE FOR SHU'CKING VEGETABLE IVORY NUTS.
Application filed October 28, 1921. Serial No. 511,124a
T all whom it may concern 1 Be it known that I, HENRY WV. CROWELL,
' a citizen of the United States, and a resident of Glen Ridge, in the county vof Essex and State of New Jersey, have invented new and useful Improvements in Machines for Shucking Vegetable Ivory Nuts, of which the following is a specification.
This invention relates in general to rotary cutters, and more particularly to a machine for shucking vegetable ivory nuts.
The objects of the invention are to provide a rotary cutter embodying novel features of construction and including a revoluble body portion having a plurality of cutting elements on its peripheral surface adapted to be thrown into cutting position by the centrifugal force developed by its peripheral surface adapted to be thrown outwardly by centrifugal force developed by revolving said body portion with their cutting edges disposed in axial planes of said body portion; to provide such a rotary cutter in which the cutters have their cutting edges curved in axial planes of said body portion; to provide a rotary cutter including a revoluble body portion or rotor having a plurality of radially disposed eyes secured in its periphery and washer-like cutting elements mounted in the said eyes whereby the cutting elements are adapted to be thrown outwardly by centrifugal force developed by the revolving motion of said portion; to provide such a cutterin which the washers are disposed in axialplanes of said body portion when in operation; to provide such a rotary cutter in which'the cutting element is adapted to be automatically moved by engagement with an un yielding surface to present different portions of the cutting edge to said surface on successive engagements of the cutting element with said surface; to provide a ma-' chine for shucking vegetable ivory nuts comprising a rotary cutter of the character described revolubly mounted in a casing; and to obtainother results and advantages as may be brought out by the following description.
Referring to the accompanying drawings, i
in which like numerals of. reference; indicate the same views,
Figure 1 is a front elevation-ofv amachinev for shucking vegetable ivory nuts constructed in accordance with my invention showing the cutting elements 'in working position;
Figure 2 is a transverse sectional view through the machine taken on the line 2- -2 of Fig. l; s
Figure 3 is a vertical longitudinal sectional view through the machine taken on' the line 3-3 of F ig. 2,, showing the rotor and cutting elements in idle position;
Figure 4 is a detached side elevation of the rotor with the screw eyes removed there from, and o Figure 5 is a development of the rotor showing the helical and circumferentially spaced arrangement of the screw eyes.-
In the embodiment of my invention shown l inthe drawings, the reference character l designates the revoluble body portion or" roparts throughout the several-- tor of the rotary cutter which in the present instance is shown in the form of a sleeve made fast upon a shaft 2 in any suitable manner so asto rotate with the shaft. The
4t are arranged in planes at right angles to the axis of the rotor as clearly shown' in Figures 2 and 3, and the inner ends of the screw eyes are riveted or otherwisepost tively secured, as at 6, against rotation'in" the rotor 1. The screw eyes 5 arearranged in two'helixes 7 and 8 as shown on thede velopment of the rotor in Figure 5 of'the drawings and a plurality of screw eyes in the present instance three, are arrange in the same axial plane. The screw eyes are spaced circumferentially of the rotor atangles of substantially 30 apart as clearly shown in Figure 2, andjwiththe above described arrangement of the screw eyes and washers, it will be seen that the cutting ele ments 3 are arranged in close proximity'tof' each other both circumferentiallys and lon-f gitudinally of the rotor, the screw eyes being longitudinally spaced on the rotor at just sufficient distances to allow a slight clearancebetvveen the edges of the adjacent cutting elements 3.
In operation of the rotary cutter above described, the shaft 2 is rapidly revolved, and the centrifugal force set up by the revolution of the rotor causes the cutting elements to be thrown outwardly so that their cutting edges are disposedin axial planes of the rotor as shown in Figure 2. An article or surface to be operated. uponby the cutter is forced intoengagement' with the edges ofthecutting elements, and the said cutting elements due to their circumferentially spaced relation on the rotor will shecessively'engage the said surface by impact; so thatthe cutting edges of the cutting elements will chip or break off portions of the surface being operated upon. The cutting elements being loosely mounted in the eyes 4 willyield slightly upon engagement with an unyielding surface so as to strike an effective glancing blow to chip or break the surface, and when the cutting elements engagethe surface at a point at one side of the ax s of the corresponding screw eye 5, the cutting, element will be slightly rotated in its ownplane in the corresponding eye l so as to present another portion of the cutting edge thereof to the surface on the next engagement of the cutting element with the surface. The cutting edges of the washer-like cutting, elements 3 are curved in axial planes of the rotor so that they. act upon. anunyielding surface with a shearing effect which facilitates in the rapid chip ping or breaking of the surface being operated upon. v i
The rotary cutter above described is particularly designed for use in machine for shucking vegetable ivory nuts, that is, for removingthe shells from the nuts. For this purpose the rotarycutter is mounted in a casing 9 which is substantially circular in cross-section and provided with axial bearings 10 at opposite ends thereof in which the shaft 2 is journaled. Portions" of the bearingslO project inwardly of the casing, as shown in Figure 3, and the rotor 1 is arrangedbetween the ends of said bearings so as to be efl ectively held against longitudinal' movement in I the casing. The shaft2 is adapted to be rapidly revolved in the bearings 10 in the direction indicated by the arrows in Figure 2 by any suitable meanssuch asthe pulley l1 and belt 12. The casing is fastened upon a table. or other suitable support by meansof bolts 18, and the front of the casing i's provided with an opening 14- through which the nut 15 to be shucliedis inserted by the hand of the operator. The nut 15 is held in the fingers of the operator as shown in Figure 2 so. as to be engaged by the cutting elements 3. As the cutting elements rapidly revolvev they chip or break off pieces of the shell of the nut and the nut is turned in the fingers of the operator-until all of the shell has been thus removed. The casing also prevents the pieces of the shellrof the nut from being scattered, and the back of the casing is preferably provided with an opening 16 to facilitate in the removing of the pieces of shell from the casing.
it will be noted that the cutting elements 3 have only a slight leverage and are cornparatively light in weight so that the force of the impact thereof with the object or surface being; operatedupon is comparatively light. The effect of the cutter is thus that of a substantially continuous cutting surface formed with a plurality of spacedv yielding cutting elements, and the. freedom of movement of the cutting elements in; all directions provides a very effective cutter for removing the shells from ivory nuts. Due to the light weight of the cuttingelements and their short leverage, there is no danger to the operators. hands, it having been found that the worst effect of engagement of the fingers with the cutting ele-- ments is a stinging sensation. The curved or'arcuate edges of the cutting elements. 3 and the close arrangement of the cutting elements in the same axial plane longitudinally of the rotor enable two adjacent cutting elements to simultaneously engage different portions of a curved surface, such as the shell of a vegetable nut, when a portion thereof is held between said adjacent cut ting elements.
While I have shown and described one possible embodimentof my invention, it will be understood that this is for the purpose of illustrating the principles thereof only, and that many modifications and changes can be inade in the detail construction of the invention without departing from the spirit or scope thereof. Therefore, I do not wish to be understood as limiting myself except as required by the following, claims when construed in the light of the prior art. I
