F'INGER-HQLD FOR PENHOLDERS.

SPECIFICATION forming part. of Letters lateiit No 768,985, dated August 30, 1904. Application filed January 19, 1 904. Serial No. 189,683. No model.)

Tn Il :ft/mr if muy concern.-

Be it known that l, Bvro.\v B. (lotus-inrit, g a citizen of thev United States. residing 1n the .soft-rubber sleeve could have nogreat tliicltt city and State ot' `t\`e.v 5orlt, have invented a new and useful linproveincnt in Finger-Holds for lenholders, ot' which the following is a i sleeve by means ot tiny air-cells distributed invention is to provide a specitication.

The object of my linger-hold for pe'nholdeis which shall be Q easy of construction and which '.vill vet present an elastic and yielding' mass to the lingertips of the writer, so that the pcnholder may i be securely grasped with little eliort, an increased degree of elasticity and smoothness be i given to t'nc writing, and writers cramp be. avoided.

ltlias heretofore heen proposed with a view l oi' attainingr the objects at which I aim to construct linger-holds for penholders of coi-lt;

but these have been found unsatisfactory by solid sot'tl rubber, since in my form the walls' reason of their comparatively unyicldin; r`

chanac-ter. ,It has also been proposed to build the linger-hold ot' sot'trubher. Now a lingerhold of a solid cylinder of soft rubber without any core of rigid material on the inside is impmcticable, since it wabblcs in writinfr.

lt has therefore been proposed to build penholders with a solid coie'or ferrule, which supports and prevents the wabbling,r of the pen. and to surround this core or foi-rule with :lsoft-rubber sleeve inthe forni Gt' a tube. Since. however, the body ot the surrounding advantage that thc lingers ofthe user displace the air from the 'very point at which the lingers rest. thus practically permitting. the lingers to come into Contact with the rigid material of the penholder with nothing but a thin 'sheath of rubber between them.

Xoivl have found that l'can. construct a linger-hold com prisng a sleeve'of soft rubber having a comparatively thin body and incaspart way oi' entirely through the body of the linger-hold. A linger-hold thus constructed has far greater elasticity than one built of of sottruhher between the air-cells are comparatively thin and can be bentand stretched with the application of the minimum force, and this remains. too, in a measure even after the rubber has grown somewhatstili with age.

In the drawings, Figure 1 shows a crosssection of a penholder and my linger-hold. Fig. 2 shows a longitudinal cross-section of a modilied form of linger-hold. Fig. 3 is aseotion ot` Fig. .2 along the'line 3 3. Fig. 4 is a longitudinal section of another modilied form ot' linger-hold. Fig. 5 a 'section of Fig. 4 along the line 5 5.

\\'hile my linger-hold may be applied to penholders of various constructions, I have shown,- to lix ideas, a holder in the form of a. stem A, having a tenori A', over which is slipped the metal core or ferrule B, having fastened in the outer end thereof the usual penholder-elip ll'. The multicellular soft-rubber sleeve l) is shown as surrounding and embracing the metal core or terrule B. Manifest-ly, however. the material of the sleeve could be extended to cover the entire penholder.

The sleeve D in Fig. 1 is constructed of soft 4rubber having a very large number of tiny ot` these little air-cells is preferably lessthar u the linger-hold.

one-ftieth ofl an inch'. the radial thickness'of the c 'vlindriv the sleeve is not over an eighth er in extreme 1 somewhat regularly distributed,k and their number is in practice even larger than I have indicated. y

1n the formof sleeve shown in -i the air-cells are again prismatie rather than polyhedral in form; but instead of running longitudinally along the sleeve they eireumferentially aroundV it at the same and ab dif'- fering radial distances from the axis of the sleeve.

ll'hile I have referred to the materiell of the sleeve as "soft rubber." it is to be understood that I include by thisterm not merely pu re soft rubber, lbut also that form of soft rnbb which pure softrnbber is mixed with terating or other efiunpounds Vfor the sa greater eheapness or for imparting eth1 sirable characterisaies to the soft rubber 1. A penholder linger-hold compris rigid core for holding the pen and a surr ing soft-rubber slee're havingvair-eell tributed throughou its mass, substanti: described.

Q. A penholder Enger-hold compris rigid tubular pen-noldng ferrule and rounding soft-rubber sleeve having ai distributed throughout its mass, substtu as described.

In testimony whereof I have signed m5 to this specification in the presence of tu scribing witnesses. v
