2 Sheets-Sheet 1 P. S. ERVIN' BERRY STEMMER HAVING HELICAL RUBBER TUBE Filed Feb. 7. 1956 FIG.
July 16, 1957 INVENTOR PRESTON S. ERVIN BERRY STEMMER HAVING A HELICAL RUBBER ATUBE:
Filed Feb. 7, 1956 P. S. ERVIN July 16, 1957 2 Sheets-Sheet' 2 INVENTOR W .V .R E S. .N O T S E R P BERRY STEMMER HAVING A HELICAL RUBBER TUBE Preston S. Ervin, Topeka, Kans. Application February 7, 1956, Serial No. 564,000 Claims. (Cl. 1465S) This invention relates to berry stemmers.
It is an object of the present invention to provide a berry stemmer which is simple and eicient in operation and is constructed so that the berry is carried around a number of times in contact with an exterior fabric wall, a sharp auger edge and an inner air containing rubber tube whereby to rub off and to catch the stem of the berry in an improved manner.
t is another object of the present invention to provide a berry stemmer of the above type which is adapted to receive and stem berries of various diameters simultaneously.
Other objects of the invention are to provide a berry stemmer bearing the above objects in mind which is of simple construction, has a minimum number of parts, is inexpensive to manufacture and eiiicient in use.
For other objects and a better understanding of the invention, reference may be had to the followingdetailed description taken in connection with the accompanying drawing, in which:
Figure 1 is a side elevational view of a preferred embodiment of the present invention shown partly in section (with parts broken away);
Fig. 2 is a top plan viewthereof Alooking along the line 2-2 of Fig. 1;
Fig. 3 is a horizontal sectional view thereof, looking along the line 3-3 of Fig. 1
Fig. 4 is an enlarged fragmentary vertical sectional view of a portion of the device;
Fig. 5 is an enlarged sectional view showing the rubber tube forming a part of the invention; and
Fig. 6 is a view similar to Fig. 5 showing a modified form of sponge rubber tube which may beemployed with the invention. .v .v
Referring now more in detail to the drawing, 10 indicates a frame which is formed at its lower portion with a plate 11 adapted to overlie the table 12, being secured thereto by an underhanging plate 13 within which is screw threaded the stud 14 having a knob 15 at its lower end and a clamp foot 16 at its upper end whereby to engage the undersurface of the table, as will be obvious. The frame 10 extending upwardly in the standard 17 which terminates at its upper end in the arcuate plate 18 to which is suitably secured a semicylindrical casing 19 formed along its open edges with the vertically spaced lugs 20. A complementary semicylindrical casing 21 disposed opposite the casing 19 is formed with the vertically spaced lugs 22, the casings 21 and 19 being yieldably secured together by means of the nut and bolt assemblies 23 which pass through the aligned lugs 20, 22 and coil springs 24 mounted thereon intermediate the nuts and the lugs 20. A washer 25 is provided intermediate the nuts and the ends of the springs. l The upper ends of the complementary casings 19, 21 are integrally formed with the frusta-conical enlarged portions 26 and 27 which cooperate to form a unitary hopper.
A separator plate 28 is mounted in the upper end of United States Patent .ICC
the cylindrical chamber thus formed at the bottom of the hopper, the separator 28 having the openings 29 whereby to limit the size of the berries passing downwardly into the cylindrical chamber. The cylindrical chamber is provided with a fabric lining 30 extending over the interior surface thereof the entire length thereof.
A horizontal bushing 31 is provided in frame 10 above the plate 11 thereof and rotatably mounts at shaft 32, the ends of the shaft 32 extending beyond frame 10 at both ends thereof. A crank arm 33 is keyed to the outer end of the shaft 32 and terminates in the rotatably mounted handle 34 whereby to impart rotary motion to shaft 32 manually and to drive the bevel gear 35 mounted on the inner end thereof. A bearing 36 is formed in the frame 10 above the plate 11 and bevel gear 35 and mounts a vertical bushing 37 within which is rotatably mounted a shaft 38, the lower end of which extends below the bearing 36 and mounts a bevel gear 39 keyed thereon and in mesh with bevel gear 35. The upper surface of the bearing 36 is inclined downwardly away from standard 17 and mounts thereon a chute 40 having the semicylindrical side wall 41 and adapted to move the berries 42 deposited from the cylindrical chamber forwardly into any container or pan on the table 12. The shaft 38 extends upwardly the entire length of the cylindrical chamber and terminates at its upper end (Fig. 2) in the cylindrical extension 43 which is journalled in the separator plate 28. i
A cylindrical auger forming member 44 is fixed to the shaft 38 within the cylindrical chamber, being slightly j spaced from the fabric lining 30 thereof.
The auger forming member 44 is provided with three helical grooves 45, 46 and 47 of large, intermediate and small size to accommodate berries of varying sizes.
A rubber tube 48 is mounted within each of the grooves 45, 46 and 47. Each of the rubber tubes 48 includes a relatively thick back portion 49 and a relatively thin outer portion 50, the portions 49 and 50 coming together in the overhanging anges 51, as shown in Fig. 5..
As shown in Fig. 4, each of the grooves 45, 46 and 47 is integrally formed with a depending sharp edge 52.
In the operation of the device, the berries are placed in the hopper and at the same time the crank handle 34 of the crank 33 is rotated to cause a counter-clockwise rotation ofthe member 44 whichV constitutes a berry carrier. As the handle 34 is rotated, the berries drop into the upper ends of the spiral and helical grooves 45,`
` or rubbed olf. The travel of the berries through these helical passageways causes the berries to rotate upon each other and against the line cloth which lines the chamber as well as the rubber tubes 48 and as a consequence the berries will be polished, trash and dirt will be removed therefrom, the stems will be detached and when discharged, the berries will be ready for use.
Referring now particularly to Fig. 6, there is shown a modified form of sponge rubber tube or member 55 designed in the same manner as the rubber tube adapted to be used instead of the tubes 48 of the previous form.
The rubber tubes 48 are filled with air to effect a cushioning action and having a one-half twist from end to end with a taper similar to that of a ychisel at the top of the tube.
The carrier 44 may be formed of any suitable material and may be provided with any number of such grooves of any varying size. As the upper ends of the grooves become aligned with the openings 29 of the separator 28, additional berries will pass downwardly. As the various sizes of berries pass into the passages, they are caught upon the rubber air tubes 48 and held to the outer edges of the auger 52, where they come into contact with the fabric lining 3i). As the berry enters the auger passage and upon the foam or sponge tube or the rubber air tube it encounters a twisting, turning and rolling motion plus a downward motion caused by the thin face of the rubber tube and its thick back plus the forward auger edge. The stems are caught between the outer auger edge sides and the fabric that is glued to the inside of the two halves that surround the auger. Thus the stems are caught, pulled, and rubbed ofI' as well as polishing the berries, and discharging them ready for use.
It will be readily apparent that the carrier may bev driven by other means than that shown, for example an electric motor, without departing from the spirit and scope of the invention. Further berries will not be admitted into the grooves from each opening 29 in the plate 28 until the latter have made one complete turn, due to the separator 28.
The sizes of the tubes 48 will, of course, vary with the size of the grooves 45, 46 and 47.
The tubes 43 are suitably mounted within the grooves 44, 46 and 47.
The rubber tubes 48 together with the auger edges 52 and the fabric lining 30 cause the berries to be pushed downward with two turning motions and three bearing surfaces: the first bearing is the rubber tubes 4S, the second is the auger edges 52 and the third is the fabric lining 3G. rThe stems, including the green, or anchor end or blossom end are taken off the berry in the opening portion of the auger groove against the canvas lining 3d, the stems being caught between the auger edges 52 and the cloth lining 30. Thus, the berries are polished, pushed and turned along by the rubber tubes 48, auger edges 52 and lining 30.
While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.
The device can be made of any suitable material, for example metals or plastics such as iron, aluminum, or Bakelite, or can be made of any combination of hard materials, such as pressed wood, pressed cloth, pressed paper, and any coloring or degree of coloring may be used in all the hard plastics material used to make machine this device, therefore, may be milled, or poured moulded, and poured moulded under pressure.
What I claim as new and desire to protect by Letters Patent of the United States. is:
` passageway, a resilient rubber air tube within each of said grooves, and an overhanging edge formed along each of said grooves, each of said resilient rubber air tubes comprising an elongated hollow rubber tube having a relatively thick inner wall and a relatively thin outer wall, said tubes being inilated with air and twisted through one-half a turn over the length of said carrier.
