STEM CUTTERS Joseph A. Schanno, College Park, Ga. Application November 2, 1955, Serial No. 544,501

11 Claims. (Cl. 30-232) This invention relates to a stem cutter andjmore particularly to a one hand operated cutter of this sort to be held substantially fiat in the hand with a blade arrangement thereon actuatable to snip stems and the like from plants, trees, bushes,vines, and in other instances for easy penetration and operation between branches or other awkward situations.

In many instances it is necessary to cut stem-like members, cords, strings, and the like where only one hand can be used to position and actuate the cutting arrangement and sometimes to hold the severed object with the same hand that cuts it. This arises in removing fruit, flowers, and other parts from their branches or stems where a clean cut must be made. For example, in thecommercial harvesting of such plants as cucumbers or the picking of fine citrus. Likewise, this would apply in theremoval of roses with stems; or cords tangled in fish nets; or many other situations. Furthermore, it is desirable that the cutter not be bulky or protrusive and that the hand be free and unencumbered so that the hand is readily inserted through branches between leaves, and all other tight situations, and that the hand be free to grasp the severed object if need be.

The primary object of this invention is to provide a cutter which is readily held close to one hand, is supported entirely by that hand, and is operated solely by a movement thereof.

Another object of this invention is to provide a cutter for one handed operation which is readily aligned on a slim stem member or the like and actuated with the one hand to snip with a minimum of difliculty. Furthermore, the device may be used to clip and hold the severed item in the same hand.

A further main important object of my invention is to provide a cutter arranged to cut the stem of a fruit with the one same hand and upon at least part of the normal grasping movement of said hand whereby the grasping action moves the cutter.

An additional object may be found in one form of this invention which may be palmed in the hand and operated solely by a type of squeezing or normal grasping action. Cutting entrance being attained by using two of the fingers as guides.

Many other objects and advantages will be'found upon an understanding of the construction of my device. Generally described without regards to the scope of coverage, one form thereof consists of a number of movable members formed flat and joined to be held flat in the palm. There is a bottom, palmjmember curved to lie across from the thumb, a first flat finger contact and blade member provided with pivot means connecting it with the palm member and normally lying adjacent the top of the palm where some of the fingers join the hand, and another blade member pivoted on the palm member above the thumb adjacent the index finger, the blades on said blade members being formed at the inside side of each nited States Patent ice thereof and the blade sides being positioned adjacent each other so that said blades intersect at the lower portion thereof forming a gap at the top thereof, said gap being positioned between two of said fingers so that a stem or the like to be cut can be aligned between the fingers and the blades moved around said stem to cut same upon the movement of the palm and the fingers to pivot said palm member and said blade members.

The above described form of my invention has been used as the illustration in the detailed description found herein which is taken in conjunction with the accompanying drawings, in which:

Fig. 1 is an elevation view of my invention shown flat in the palm of a dotted diagrammatic hand about to clip the stem from a plant.

Fig. 2 is an end elevation view taken at the right end of the device in Fig. 1.

Fig. 3 is a view similar to that in Fig. l but with the hand therein squeezed and doubled up in a manner of grasping which has caused my device to close its blades.

Fig. 4 is an elevation view of the back of my invention removed from the hand.

This invention is normally used on the hand and on either one, so in the present drawings it is shown for a right hand It) with palm l2, thumb 14, index finger 16, and second, third and fourth fingers 18 which are shown as though flat on a table or vertical in the air. The cutter 20 is comprised of a strip-like curved, palm actuating member 22 wider than the normal hand 10 and pivotally joined by braded pivot pin 24 on one end of a first blade member 26 which is constructed from flat metal plate with a sharp cutting edge 28 on the inner side thereof and having slightly indented fingercontact portions 36 on the top thereof. Blade member 26 normally lies at the top of the hand in the palm just at the junction of the second, third, and fourth fingers. Palm member 22 is joined at the other end thereof by braded pivot pin 32 to one end 34 of a pivoted, drive'link 36 having its other end thereof 38 pivotally joined by braded pin 46 to one end 42 of another second flat blade member 44 with a cutting blade 46 on the inner side thereof adjacent the cutting blade edge 28.

Second blade member 44 is formed with a flat, roundedend protrusion 48 lapping over a portion of first blade member 26 and juxtapositioned thereon to receive an adjustable bolt pivot pin 50 connecting the two blade members together for movement relative to each other, about the common pin 50 and their

respective pivot pins

24, 40. It is pointed out the mean or substantially cen tral axis X between cutting edges 23, 46 with respective axesY and Z, all intersecting at O, is offset laterally from the pivot pin 50, having axes V and H, a distance shown as D in the drawing Fig. 1. This arrangement upon actuation of

blade members

26, 44 causes blade 46 to advance at a faster rate of blade surface toward axis X than the other blade '28 which compels blade 46 to sever one side of a stem or the like between the blades at a rate of faster penetration on that side than the other. This prevents the two blades from advancing substantially equally and meeting at the center which would press then suddenly snap the severed object with some jar and vibration not present in the disclosed arrangement. Less shock, jar, and vibration means less tiring work. The

blades

26, 44 are limited in relative movement by means of stop pins 51 protruding adjacent link 36 limiting its movement.

Extending from an opening 52 at the bottom of blade member 26 is one end 54 of a spring 56 hooked in the opening and leading across to a similar opening 58 with the other end 60 hooked therein. In normal position of the

ayrsasrs blade members

26, 44 relative to each other the spring 55 is under tension very little if any but upon closing of the edges 28, 46 the spring 56 stretches under tension tending to open the blades to normal position when released.

For ease in holding the cutter a loop of leather boot or the like 62 is attached on the back of blade 26 by means of hammered rads 64 forming a stall for the three fingersld. A similar boot stall 66 is formed and attached by brads 64 on the back of blade 44 for the index finger 16. The

stalls

62, 64 by their separate loops form an entrance along axis X between their ends. The device is held in the hand with the fingers in their respective stalls 62,. 66 in the manner shown by Fig. l and with the arcuate palm member 22 nested in the heel of the palm and with link 36 adjacent the thumb 1.4, alldepending upon the particular size and comfort of the individual. To make this more comfortable, a foam rubber strip or the like 67 is attached to. member 22 By squeezing the hand lit to double up the palm l2 and bending the fingers. l6, 18 the device is brought to the position in Fig. 3 where blades 28, 46 meet and out anything confined therebetween. For example, if the stem 68 with bad 70 in Fig. 1 were guided between the stalls 62;, 64 and between the blades 28, 46 it would be readily severed upon one simple forward and squeezing hand action and hand it) can close on bud 70 if desired. When the hand is relaxed, spring 56 will return the blades to normal. Therefore normal grasping of a fruit would also operate the cutter.

It is pointed out that the device may take other forms or refinements. For example, an entire mitten or glove may be used in place of the abbreviated

boots

62, 66 or all of that may be eliminated and simple stop barrier members used adjacent the finger 1 6 and the. first finger 18. to hold the fingers apart. In cutting fruit, such as citrus oranges, the device is practically held entirely nested within the hand and flat in the palm by virtue of its flatness. and thinness as may be seen in Fig. 2. With. this arrangement, the hand can dart in and out between branches cutting stems in a most expedient manner, or the hand can be moved straight forward on a branch down a line of fruit. And as mentioned. at the general outlines of objects at the beginning hereof, the position and arrangement of this device allows one to move into place. Onto the stern and cut same at the same time the cutting hand grasps or. holds the fruit.
