Description
FIELD OF THE INVENTION
The present invention relates try portable battery powered shredders and more particularly to ;such portable battery powered shredders for shredding the readi_1y yiel.dir~g parts of a plant, such as the leaves, flowers, and roo~s, to render products such as spices, herbs, medicinal ingredie~zts in a shredded form.
BACKGROUND OF THE INVENTION
spices, herbs, and other parts of various pl.ant-s, such as the leaves, flowers, and roots, and ~~o on, have been used for many years in cooking. Typ:ir_ally, it i.s reces nary, or at least useful, to grind or in some manner cut the desired parts of the plant into very small pieces. These pieces <~re added to the food being cooked, as is well-known.
Also, over many years, it has been learned that. parts of various plants could be used medicinally, such as t.a decrease the sensation of pain or to improve a person's health. A disr_.ussed in U.S. patent 5,788,92, for the last few uundred years, plants such as camphor and peppermint have been used to ameliorate the pain of skin lesions, and witchhazel oi.l has been found to relieve dermal and muscular aches and pains. Further, for several centuries, capsaicin, the active ingredient irr chili peppers, has been used in a variety of mariners to treat v;~riaus types of rural pain.
Similarly to preparation for use in food, it is typically necessary, or at least useful, to grind, or in some manner cut, t:he desired parts of the plaint into very small pieces.
Many types of grinders a.re avai_l.able for grirnding spices, and other parts of plants, for use in coo~;ing, for use in natural medicine, and so on. C)ne such spice grinder is taugrit in U.S.
patent 5,86.5,384 issued February 2, 1999, to Pai. This spice grinder is used to grind spices, :>ucri as black peppers, into very small particles of substantially uniform size. The raw black peppers are retained in the space grinder, and a portion of t:he black peppers are ground, as reqL~v~re~:i. The particles drop out of the bottom of the spice grinder a:> t:2ey are ground.
The ac'~ual grinding mechanism iz the spice grinder comprises a conical grinding disk and a grindin~~ base. The grinding disk has a polygonal hole that receives a spin<~le t:herethrough. A plural.it:y of oblique radial disk wings extend .integrally from the periphery of a wall defining the polygonal hole. The end of the disk wings are configured to be pointed in shape, f_or moving the spice to be grol.znd. The grinding disk further has a multiplicity of obliquely arranged teeth below the wings for moving the spice. The grinding base is a circular stepped structure having a larger base rim at a lower portion thereof and a grinding cylinder of a smaller diameter at an upper end thereof. The base rim teas a notch at either side thereof, and the grinding cylinder i~> provided with an indentation at either side thereof corresponding to the notches for retaining the ribs so that the grinding base may be secured and located in the partition seat. In addition, r_he periphery of an i.r~ner wall of the grinding cylinder is provided with a plurality of oblique grinding teeth. Since the inner diameter of the grinding cylinder is slightly smaller than the outer di.amet=er of the bottom grinding disk, there is always a clearance x:~etween the grinding disk and the grinding cylinder. Therefore, when the grinding disk rotates, pieces of spice fal7_ among the c:~isk wings, and are pushed about by the disk wings and the disk teeth, so as to displace along the grinding teeth and thus be ground, the ground particles displace dawnwardly into the clearance betGaeen 'the grinding teeth, and the disk teeth and drop outs of the grinding device. Powdered spice of uniform particle size may thus be ac:zieved.
Such spice grinders can only grind certain types of material, arid are especially good at grinding hard parts of a p:Lant, such as black peppers, and the like, and are not meant to grind the softer readily yielding portions of the plant, such as the leaves, flowers, and roots. Such readily yielding portions of the plant, such as the leaves, flowers, and rc~ats, must be cut into small usable pieces in some other manner.
It .is an object of the present; invention to provide a portable battery power shredder for used in sh~_edding readily yielding parts af_ a plant.

_ g _ DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
Reference will now be made tc Figures 1 through 7, which show a preferred embodiment of the portab~.e battery powered shredder of the present invention, as indicated by general. reference numeral 20. The portable battery powered shredder 20 is for' use in shredding an apportionment of readily yielding parts of a plant, as indicated by the general ref_erencF~ numeral 22 in Figure 1, such as the leaves, flowers, and roots, to render products such as spices, herbs, medicinal ingredients in a ;shredded form. The portable battery powered shredder 20 compri:>es a substantially cylindrically shaped outer housing 30 having a substantially hollow interior 32 defined by an interior wall surface 34, and having a top end 36 and a bottom end 38. The outer housing 30 is preferably made from a robust plastic material, but may also be made fram a metal material, or any other suitable material.
A receptacle means comprising a receptacle 40 ire the form of a bowl that is preferably ma<~e from metal material, such as stainless steel, or alternatively from a plastic material, or from any other suitable material. The re~Jeptacle 40 is mounted in the interior 32 of the outer housing 30 and is retained iri place by means of interference fit. The rec.;epvacle 40 has a concave annular recess 42 ar~d the outer housing 3!~ has a co-operating convex annular projection 39 in its interior wall surface 34 to form the interference fit. In this manner, the receptacle 40 is removable and replaceable.
There is a first opening 50 disposed in one end of the cylindrically shaped outer housing 30, specifically the top end 36 in the preferred embodiment, as illustrated, to permit access to the interior 32 of the outer housing 30, especially to the receptacle 40.
A lid means for selectively precluding access to the receptacle 40 comprises a disr~ shaped lid 60 that is removable from and replaceable onto the outer housing 30. Accordingly, the lid E0 can double as a retaining dish for retaining the shredded apportionment of readily yielding parts 22. of a plant, when the lid 60 is removed from the outer housing 30. The lid ~0 is retained in place by means of interference fit of a small protuberance 64 on the interior wall surface 66 of the lid 60 with a co-operati.ng circularly shaped indentation 3'7 ~~isposed at one end of an horizontally disposed channel 35 in the exterior wail surface 33 of the reduced diameter p;~rtion 31 of the outer housing 30. A
vertically disposed channel tnot shown) is connected with the opposite other end of the horizont:al:Ly d~.sposed channel 35 and is open to the top end 36 of the outer housing 30. In use, when the lid 60 is put in place on the outer housing 30, the protuberance 64 engages the vertically disposed channel anal 'travels down the vertically disposed channel whi__e the lid i~0 is being pushed downwardly onto the outer hcusinc~ 30. When the lid 60 has been pushed all the way down onto the outer housing 30, tlue lid 60 is then turned (about one quarter of a full rotation) so as to cause the protuberance 64 to engage the horizontally disposed channel 35, until the protuberance 64 reaches the co-operating circularly shaped indentation 37. The protL.berance 64 engages the co-operating circularly shaped indentation 37 such that there is an interference fit that temporarily locks the lid 60 in place. The Iid 60 is removed in an oppositely directed manner.
There is also a second opening 52 in the opposite other end, namely the bottom end 38, of the cylindrir_ally shaped outer housing 30. An end cap 62 is provided for_ selectively closing the second opening 52.
A shredding means comprising a sharp blade 70 preferably made from metal material, such as stYainless steel, is operatively disposed within the receptacle 40. More specifically, the sharp blade 70 is mounted on the shaft '7a? of an electrically powered motor 74 and is thereby connected ._n driving relation with the sharp blade 70, and is retained on the shaft 72 by a cap member 73 threadibly engaged on the er~d of the shaft 72. The shaft 72 of the electrically powered motor 74 extends through a co-operating aperture 44 in the bottom portion of the metal receptacle 40. The electrically powered motor 74 is preferably a high-speed high-torque motor, so as to permit ea:,y :shredding of readi7_y yielding parts 22 of a plant.
A means for powering the electrically powered motor 74 preferably comprises a rechargeable battery 76 securel~r mounted in the bottom portion of the outer housing 30. A. jack 78 for receiving the plug of a recharges (not shown) is mounted in the interior wal_1_ surface 34 of the outer housing 30. The rechargeable battery 76 is connected in electrically conductive relation with the electrically powered motor 74 by means of ~rires 80 and first and second switch means 81,82 electrically connected in series one witru the other. The first and second switch means 81,82 provide means to permit selective actuation of the electrically powered motor 74. In the preferred embc>dvwme::~t, as illustrated, the first switch means 81 comprises a conventional manually operable momentary contact sinr~le-pole single-throw switch mounted an the outer housing 30 so as to be readily ~~ccessible. The second switch means 82 comprises a pair of normally open Contacts 85a, 85b mounted in a recess 86 in the interior wall_ starface 34 of the outer housing 30. The pair of contacts 82 is elec.w~rically open when the lid 60 is not in place on the outer hou~:ing 3c~, such as can be seen in Figure 1. Further, the pair ofc:on1_act,s 82 becomes electrically closed by the plunger when the Lid 60 is positioned in place 84 on the outer housincx 30, such as earl be seen in Figure 2. In this manner, the electrically powered motor 74 can be powered only when the lid 50 is in place, thus precluding unsafe operation of the portable battery t6 powered shredder 20.
As can best be seen in Figure 3, the outer housing 30 encloses the receptacle 40, the sharp blade ?0, the electrically powered motor 74, and the rechargeable battery 76.
The present invention also relates to a method of shredding an apportionment of readily yielding parts 2.2 of a plant in a portable battery 76 powered shredder 20. ~,he method comprises various steps, as now discussed. In use, the portable battery '7H powered shredder 20 is pl,~ced upright, as can best be seen in Figure 4A.
The lid 60 is then removed, as can best be seen in Figure 4B, so as to access the interior 32 of the portable battery 76 powered shredder 20. An apportionment of readily yielding parts 22 of a plant to be shredded is passed through the opening and deposited into the receptacle 40, as indicated by arrow "A" in Figure 4C.
The lid 60 is then replaced onto t:he outer housing 30, as can best be seen in Figure 4D, thus r.losing the second switch, which is the safety switch. The first switch i~> then manually depressed, as can best be seen in Figure 4E, thereby c:las~.ng an electrical circuit including the electrically powered motor 74, thus powering the motor 74 so as to actuate a shredding means - namely the sharp blade 70 - within the receptacle 40. The apportionment is trim shredded by the sharp blade 70 upon t:he selective actuation of the e7_ectrically powered orator 7~1. The resulting shredded appcrtionment of readily yielding- pay°ts 22 of a plant is best seen in Figure 4F. The apportionment _i.s subsequently removed from the receptacle means by turning the ~;ortable battery ~6 powered shredder 20 upside dawn, as can ~~est be seen in Figure 4G, thus causing the shredded apportionment: of readily yielding parts 22 of a plant to fall into the lid E~O. Removing the shredded apportionment of the plant Pram the ~;hredder 20 is accomplished by separating the outer housing 30 from the lid 60, as carp best be seen in Figure 4H, thus allowing access to the shredded apportionment of readily yielding parts 22 of a plant in the l.id 60, and finally collecting the shredcLed apportionment from the lid 50.
As can be understood from the above description and from the accompanying drawings, the portable battery powered shredder of the present invention can easily shred the readily yielding parts of a plant, such as the leaves, flower;, ,end roots, to render products such as spices, herbs, medicinal incfredients in a shredded form, which is unknown in the prior art.
Other 'Variations of the above p:cinci_ples will be apparent to those who are knowledgeable in the field of the invention, and such - I_4 -variations are considered to be within the scope of tree present invention. Further, other modifications and alterations may be used in the design and manufactures ci- the apparatus of 'the present invention without departing from the spirit and scope of the accorr~panying claims .
The present invention relates try portable battery powered shredders and more particularly to ;such portable battery powered shredders for shredding the readi_1y yiel.dir~g parts of a plant, such as the leaves, flowers, and roo~s, to render products such as spices, herbs, medicinal ingredie~zts in a shredded form.

There is a first opening 50 disposed in one end of the cylindrically shaped outer housing 30, specifically the top end 36 in the preferred embodiment, as illustrated, to permit access to the interior 32 of the outer housing 30, especially to the receptacle 40.
A lid means for selectively precluding access to the receptacle 40 comprises a disr~ shaped lid 60 that is removable from and replaceable onto the outer housing 30. Accordingly, the lid E0 can double as a retaining dish for retaining the shredded apportionment of readily yielding parts 22. of a plant, when the lid 60 is removed from the outer housing 30. The lid ~0 is retained in place by means of interference fit of a small protuberance 64 on the interior wall surface 66 of the lid 60 with a co-operati.ng circularly shaped indentation 3'7 ~~isposed at one end of an horizontally disposed channel 35 in the exterior wail surface 33 of the reduced diameter p;~rtion 31 of the outer housing 30. A
vertically disposed channel tnot shown) is connected with the opposite other end of the horizont:al:Ly d~.sposed channel 35 and is open to the top end 36 of the outer housing 30. In use, when the lid 60 is put in place on the outer housing 30, the protuberance 64 engages the vertically disposed channel anal 'travels down the vertically disposed channel whi__e the lid i~0 is being pushed downwardly onto the outer hcusinc~ 30. When the lid 60 has been pushed all the way down onto the outer housing 30, tlue lid 60 is then turned (about one quarter of a full rotation) so as to cause the protuberance 64 to engage the horizontally disposed channel 35, until the protuberance 64 reaches the co-operating circularly shaped indentation 37. The protL.berance 64 engages the co-operating circularly shaped indentation 37 such that there is an interference fit that temporarily locks the lid 60 in place. The Iid 60 is removed in an oppositely directed manner.
There is also a second opening 52 in the opposite other end, namely the bottom end 38, of the cylindrir_ally shaped outer housing 30. An end cap 62 is provided for_ selectively closing the second opening 52.
A shredding means comprising a sharp blade 70 preferably made from metal material, such as stYainless steel, is operatively disposed within the receptacle 40. More specifically, the sharp blade 70 is mounted on the shaft '7a? of an electrically powered motor 74 and is thereby connected ._n driving relation with the sharp blade 70, and is retained on the shaft 72 by a cap member 73 threadibly engaged on the er~d of the shaft 72. The shaft 72 of the electrically powered motor 74 extends through a co-operating aperture 44 in the bottom portion of the metal receptacle 40. The electrically powered motor 74 is preferably a high-speed high-torque motor, so as to permit ea:,y :shredding of readi7_y yielding parts 22 of a plant.
A means for powering the electrically powered motor 74 preferably comprises a rechargeable battery 76 securel~r mounted in the bottom portion of the outer housing 30. A. jack 78 for receiving the plug of a recharges (not shown) is mounted in the interior wal_1_ surface 34 of the outer housing 30. The rechargeable battery 76 is connected in electrically conductive relation with the electrically powered motor 74 by means of ~rires 80 and first and second switch means 81,82 electrically connected in series one witru the other. The first and second switch means 81,82 provide means to permit selective actuation of the electrically powered motor 74. In the preferred embc>dvwme::~t, as illustrated, the first switch means 81 comprises a conventional manually operable momentary contact sinr~le-pole single-throw switch mounted an the outer housing 30 so as to be readily ~~ccessible. The second switch means 82 comprises a pair of normally open Contacts 85a, 85b mounted in a recess 86 in the interior wall_ starface 34 of the outer housing 30. The pair of contacts 82 is elec.w~rically open when the lid 60 is not in place on the outer hou~:ing 3c~, such as can be seen in Figure 1. Further, the pair ofc:on1_act,s 82 becomes electrically closed by the plunger when the Lid 60 is positioned in place 84 on the outer housincx 30, such as earl be seen in Figure 2. In this manner, the electrically powered motor 74 can be powered only when the lid 50 is in place, thus precluding unsafe operation of the portable battery t6 powered shredder 20.
As can best be seen in Figure 3, the outer housing 30 encloses the receptacle 40, the sharp blade ?0, the electrically powered motor 74, and the rechargeable battery 76.
The present invention also relates to a method of shredding an apportionment of readily yielding parts 2.2 of a plant in a portable battery 76 powered shredder 20. ~,he method comprises various steps, as now discussed. In use, the portable battery '7H powered shredder 20 is pl,~ced upright, as can best be seen in Figure 4A.
The lid 60 is then removed, as can best be seen in Figure 4B, so as to access the interior 32 of the portable battery 76 powered shredder 20. An apportionment of readily yielding parts 22 of a plant to be shredded is passed through the opening and deposited into the receptacle 40, as indicated by arrow "A" in Figure 4C.
The lid 60 is then replaced onto t:he outer housing 30, as can best be seen in Figure 4D, thus r.losing the second switch, which is the safety switch. The first switch i~> then manually depressed, as can best be seen in Figure 4E, thereby c:las~.ng an electrical circuit including the electrically powered motor 74, thus powering the motor 74 so as to actuate a shredding means - namely the sharp blade 70 - within the receptacle 40. The apportionment is trim shredded by the sharp blade 70 upon t:he selective actuation of the e7_ectrically powered orator 7~1. The resulting shredded appcrtionment of readily yielding- pay°ts 22 of a plant is best seen in Figure 4F. The apportionment _i.s subsequently removed from the receptacle means by turning the ~;ortable battery ~6 powered shredder 20 upside dawn, as can ~~est be seen in Figure 4G, thus causing the shredded apportionment: of readily yielding parts 22 of a plant to fall into the lid E~O. Removing the shredded apportionment of the plant Pram the ~;hredder 20 is accomplished by separating the outer housing 30 from the lid 60, as carp best be seen in Figure 4H, thus allowing access to the shredded apportionment of readily yielding parts 22 of a plant in the l.id 60, and finally collecting the shredcLed apportionment from the lid 50.
As can be understood from the above description and from the accompanying drawings, the portable battery powered shredder of the present invention can easily shred the readily yielding parts of a plant, such as the leaves, flower;, ,end roots, to render products such as spices, herbs, medicinal incfredients in a shredded form, which is unknown in the prior art.
Other 'Variations of the above p:cinci_ples will be apparent to those who are knowledgeable in the field of the invention, and such - I_4 -variations are considered to be within the scope of tree present invention. Further, other modifications and alterations may be used in the design and manufactures ci- the apparatus of 'the present invention without departing from the spirit and scope of the accorr~panying claims .
