SPECIFICATIQN forming part of Letters Patent No. 301,056, dated June 2%, 1884-.

Application filed July 3, 1883.

.To all w/z, m, t may concern:

Be it known that I, JOHN C. SHARING, of

' Jersey City, Hudson county, in the State of New Jersey, have invented a new and useful Improvement in Pencil-Gases; and I do hereby declare that the following is a full and accurate description of the same.

This invention relates to an improvement on the pencil-case for which Letters Patent No. 214,820 were granted to me on the 29th day of April, 1879. In that patent I have described a pencil-ease containing a pencil holder or point arranged to have a longitudinal movement 4of protrusion and retraction, being actuated in the former direction by a coiled spring within the case arranged to expand or contract in a line axial to itself and the case, and actuated in the other direction by the rotation of a cylindrical shell provided with the spiral groove commonly used for that purpose. \Vhen the pencil-holding point has been retracted, a small detent arrests the spirally-grooved shell in its rotation, and retains the pencil-holder within the case. IVhen it is desired to protrude the pencil-point the detent is withdrawn, and the coiled spring immediately acts in its axial direction and the pencil is protruded. In the improvement described herein I substitute i'or the coiled spring a spiral spring acting in a direction transverse to the axis of its coil and of the pencil-case, and instead of attaching said spring to act directly upon the pencil holder or point, I now attach it to the spirally-grooved cylindrical shell, so that the pencil holder or point is caused to protrude by the revolution of said grooved shell when actuated by the expansion of the coil or" said spring, and to b e retracted by the revolution of said shell in an opposite direction, actuated by the fingers of the user, the spring being then contracted or wound up; and instead of the detent-sleeve described in my said patent, I terminate the. spiral groove with a shortsection of one of its edges eut parallel with the axis oih the case, and arrest the traveling stud upon said longitudinal section of the spiral groove. A slight push upon the upper end of the pencil-point moves the traveling stud ofi" its rest into the spiral groove, and the spring then rotates the grooved sleeve and protrndes the pencilholder.

(No model.)

Having now pointed out the differences between my invention and that which was previously known, I will more particularly describe it, having refereuceto the accompanying drawings, wherein- Figure l is ainexterior view of my pencilcase. Fig. 2 is a similar View of the operative parts, the exterior ornamental shell being removed. Fig. 3 is a longitudinal section of the same.

A is the pencil holder or point, provided with y c, in which the stud d (protruding from the tube a) slides, and not only limits the longitudinal motion of said tube A a, but also prevents any rotation of the same.

Outside the tube l there is at the upper end, covering theslot c, a sleeve, E, having aspiral groove, c, into which the pin (l protrudes. The sleeve E is restrained from longitudinal movement, but may revolve. When it is revolved, the pin cl is caused to move along the slot c in one direction or another, according to the direction of the sleeves rotation. This is a common way of moving the pen-point out of or into its ease, the rotation ofrsaid sleeve being effected by the fingers of the user. My present invention substitutes for other modes of applying force to etlect a rotation of said sleeve a spiral spring, F, one end of which is secured to the non-rotating tube B, and the other end is attached to the rotating tube E, andthe coils are disposed in a direction which will cause theni in unwinding to so rotate the sleeve E that the pencil A will be protruded. It will be evident, however, that so far as the mechanical effects are concerned the invention would not be changed if the" uneoiling spring should cause the pencil-point to withdraw into its case; but the means for releasing said spring would be less simple and direct than I have herein provided, and for that reason only I prefer the organization shown. The arrival of thestud d at the forward or inner end of the slot c limits the forward movement or protrusion of the pencil-holder A, and at the same time arrests the rotation of the sleeve E. The

arrival of said stud at the `other or outer end of said slot in the same way limits the movements of rsaid parts in the opposite directions. The pencil-point is drawn into the case B by a rotation of the sleeve E in the direction of the arrow, and therefore by contact ofthe pin d with the side g of the slot e, and therefore if at its upper or outer extremity the side h of thel slot e is cut in the direction of the axis, as at z', the counter rotation` of the sleeve E will cause the pin d to engage the surface z', and the parts will be arrested and so held until the tube A a has been pushed forward far enough to passagain into the groove e, and in contact with the oblique surface of h. These operative parts are inclosed within an orna- The section 7c covers the point, and is rigidly secured to the tube B. The section Z vis similarly secured to the sleeve E, so that by holdingthese sections in the fingers the sleeve E may be rotated. The section M covers the extremity of nal part i of the groove e.

the tube a, and has a longitudinal movement in section Z, so that pressure by theV finger upon said section m pushes said tube a end- Wise, and moves the stud eZ off lthe longitudi- .Therefore a forci- 1 ble rotation of the section Z and' the sleeve E other is merely the usual one, but that they might be differently located without changing the mechanical effects in any way.

Having described my invention, what I claim as new ist l. A pencil holder or point, A, adapted to move in its case longitudinally for the purpose of protruding or retracting it, a stud, d, attached to said pencil holder or point, a sleeve, E, provided with a spiral groove wherein said stud Z may travel, combined with a spiral spring, F, which acts in a direction transverse to the axis of said pencil, whereby said sleeve may be rotated in one direction bythe ngers, and in the opposite direction automatically by said spring and a detent-surface, t', substantially as shown, and for the purpose set forth.

2. A pencil-case tube, B, and a pencil-holder, A a, fitted to slide therein to protrude or retreat, as set forth, combined withapart having a spiral groove, e, a stud, d, projecting from said pencil-holder and traveling in said groove, a spiral spring, F, coiled around said pencil-case, and adapted to rotate'said casein relation to the part containing the spiral groove e, whereby said stud may be caused to traverse said groove, and a detent to hold said pencil-carrier when drawn into the case, adapted to be released by an endwise push of the upper end of the pencil-holder in the direction of the axis of the pencil.

3. The pencil-holder A, fitted to slide Within the case B, which is provided with a longitudinal slot, c, the sleeve E, provided with the spiral slot e, the pin (Z, projecting from said pencil-holder into and through the slotsI c e, the spiral spring coiled about the case A and adapted to rotate .the sleeve E by its recoil, substantially as set forth, the detent Z, and the inelosing ornamental shell in three parts, k Z on, substantially as set forth.
