TO dZ Z LU YZOWZt-t mag concern." v a Be it known that L- Crmnnns SLoc M, a citizen of the UnitedStatesanda; resident of Newark, county ofEsseX, and-Stateof New Jersey, have invented certain newand useful Improvements :in Grips for Penholders, 1 of which the following is a specification.

- Thisinvention relates to animproved grip for ipen holders or for pencils, but in this specification it is described as i applied to a pen holder, but it will-be understood that it can be 'used on any kind-of writing-instrument, being designed :to Zreceivethe thumb andftwo first fingers "of the hand and to provide rests for the thumb and these fingers, when they are injproper .position, -for writing with freedom and comfort and at the same time to give 'sufiicient power-s'o as'to makethe writing easy.

Thegrip is designed particularly for the use of pupils in writing, and :is designed to 'put the hand ina position that overcomes theten'dency to write by-g'ripping the-fingers aroundthe Writing instrument in a cramped position and writing with a finger movement,thus encouraging the arm movement, and while the grip is thus particularly adapted for-pupils, it can also bej'used by writers in general and 'conduce's'to greater comfort "and -mor e-;perfectwriting.

. The grip can be made in any suitable form and the finger rests are suitably, di sposed "around a shank'of the writing implenient, the preferred form described in the specification and illustrated in thedrawing consisting of. a sleeve which can be slipped over a pen holder or a pencil and can be .made to fit a certain size holder,.-or'it can be made of spring material and split so that it is adapted fora number of'diiferent sizes, being held in place by the spring action of the material, and I al'sodesire to make the finger rests of the same size as the sleeve, the preferred way being by: striking up the finger rests from the material, thus cheapening the cost of production and making a grip that is of good appearance.

In the drawing I have illustrated the improved grip as appliecl to a pen holder, and in Figure 1 I show a perspective view of the grip, a pen holder being shown in dotted outline and a human hand being also shown in dotted outline to illustrate the position of the grip in the hand. Fig. 2 is an enlarged front view of the grip. Fig. 3 is a e emanate of Lett eisPatntw @P'ateiitetl Ja'n. 18,1916.1 "Appliceti rilif filed aii'rii ao, 1-915! {serial em gre.

perspectiwe "view with the :grip shown. in

Fig. 1 turned over so as to illustrate the bottom side thereof, and Fig. 4 is a section. on line 4, 4, in Fig.3.

In the drawingI illustrate an ordinary pen holder 10 which is provided with the improved grip, the grip in the illustration being of the type that is formed of spring material,.preferably spring metal, bent into the shape of a sleeve, this in order to make it adjustable and to give itthe proper spring being usually splitlongitudinally. The sleevell is preferably'made of spring metal and-I have found in order to make it light that aluminum is adesirable material to use. Thesleeve 11 is split as at 12, which split can be suitably disposed as desired, but I prefer to form the split so that it avoids the finger rests andleaves enough space between the finger rests and the split to prevent weakening of the material andthus sleeve and I ma provide the finger: use;

with suitable means for preventing slipping of the fingerfrom" the tablet, this being usually done by providing a marginal flange 15. The tablet 13 on the top of the holder is arranged near the forward end of the grip, the forward end, for identification, being that end which is nearest to the end of the pen holder that receives the pen point-1 6. At a material distance in rear of the tablet on the top of the grip is a Substan- I tiallyvertically arranged tablet 17 which forms a rest for the thumb and is provided with similar 'meansfor preventing the slip ping 50f the thumb, in the form shown this being done by providing the tablet 17 with the marginal flange 18. These tablets when struck up from the shell of the grip, when the grip is made in the form of a sleeve, are tangential and are connected at points with the undisturbed material of the shell, these connecting strips being substantially flush with the outside of the sleeve as at 19 and 20.

The tablets are preferably made of semicircular halves which are struck up from both sides of said flush parts 19 and 20 to form the tangential tablets of sufiicient stiffness and adequate surface.

On the side of the grip opposite the side on which the vertical tablet17 is placed and at the lower part thereof is arranged'a wing 21 struck up from the material ofthe sleeve 11 and being obliquely arranged slightly' in rear of the tablet 13. The wing provides a rest for the side of the second finger, and when the second finger rests against the wing it is held against slipping back along the grip, as will be readily seen from Fig. 1,

and inorder to prevent any unpleasant projection in the groove or channel in which the second finger rests I prefer to provide a part 22 which is bent slightly outward substantially parallel with the wing 21, but this latter portion 22 is not absolutely essen tial, but it does, however, assist the second finger in. placing itself in position against the wing; 21. These finger rests are so disposed that they indicate proper positions of the thumb and the first two fingers of the hand and tend to overcome any tendency that a pupil might have to cramping the fingers and to writing with a finger movement which instructors find is a ditficult fault to correct when once established. To further prevent any tendency to cramp the fingers, and to. prevent, especially the index finger, from riding back along the grip, I provide a raised portion in rear of the top tablet of the grip, this raised portion being, of any suitable form, the grip as illustrated in the drawing having the projection formed in the shape of knobs or protuberances 28 i whiclnwhile they are not sharp, are small enough to provide gripping surfaces for the finger and prevent its slipping back along the grip.

The tangential disposition of the tablets gives them an amount of spring which forms a resilient surface against which the thumb and forefinger are pressed, and in this way the fatigue of grasping the pencil or pen is minimized. 7 Having thus described my invention, I claim:

1, A grip for pen holders comprising a shank having a tablet on the top near the front, a second tablet at one side and verside opposite the second tablet, the wing being slightly in rear of the first tablet.

2. Agrip for pen holders comprising a shank having asubstantially flat horizontal tablet on the top near its front end, a substantially fiat vertical tablet on one side of the shankin rear: of the horizontal tablet, and a wing projecting from the lower part of the side opposite the vertical tablet, the wibnlg being slightly in rear of the horizontal a et. r

3. A grip for pen holders comprising a sleeve having a tablet'struck up tangentially therefrom near its front end at the top, a second tablet struck up tangentially therefrom on one side in rear of the first tablet, the second tablet beingvertically arranged, and a wing struck up from the sleeve at a point slightlyin rear of the first tablet and at the lower part of the side opposite the side on which the second tablet is placed, the wing being obliquely arranged with its forward upper end tangential to the sleeve.

4. A grip for pen holders comprising a sleeve having a tablet struck up therefrom near its front end at the top, a second tablet struck up therefrom on one side in rear of the first tablet, the second tablet being vertically arranged, a wing struck up from the sleeve at a point slightly in rear of the first tablet and at the lower part of the side 0pposite theside on which the second tablet is placed, 'and transversely arranged raised portions struck up from the sleeve immediately in rear of the first-mentioned tablet.

5. A, grip for pen holders comprising a split sleeve of sheet material, semi-circular parts struck up therefrom to form a tangential tablet on the top near its frontend, semi-circular parts struck up therefrom to form a second tangential tablet vertically arranged on one side in rear of the first tablet, and an obliquely arranged wing at the lower part of the side oppositethe second tablet and slightly in rear of the first tablet.

In testimony that I claim the foregoing, I
