PEN AND PENCIL HOLDER.

SPECIFICATION forming part of Letters latent No. 420,083, dated January 28, 1890.

Application tiled May 16, 1889.

fom/,ZZ whom it may concern:

Be it known that I, ULRICH BOHREN, a citizen of the United States, residing at Hoboken, in the county of Hudson land State of New Jersey, have invented new and useful lImprovements in Pen and Pencil Holders, of which the following is a specification.y

This invention relates to a pen and pencil holder of that class which I have described in Letters Patent No. 387,042, granted to me July 31,1888.

The improvements which constitute the subject-matter of'my present application for a patent are pointed outin the following specification and claims, and illustrated in the accompanying drawings, in which- Figure l represents an elevation, the outsidecasing being partlycut -away to expose the working parts when the device is adj usted to operate the pencil, both the pencil andthe pen being retracted. Fig. 2 is a longitudinal central section in the plane Va;

Fig. et. Fig. 3 lis a similar view when the pencilis pushed out ready foruse. Fig. 4- is a. transverse section in the plane y y, Fig. l. Fig. 5 is an elevation of the tube which contains the guide-groove, which, togetherwith a rotating latch, controls the position of the pen or pencil. Fig. 6 is alongitudinal central section of this tube..` Fig. 7 is a longitudinal section of .aV portion of the pen and pencil. holder, showing. portions. thereof in elevation in thel .plane tt, Fig. 4; Fig. 8 is a transverse section in the plane w w, Fig. l. Fig. 9 is alongitudinal central section, partly in elevation, when the holder is adjusted to operate the pen. Fig. l0 isa 'longitudinal central section in the plane o o, Fig; l2, when the pen is'retracted. Fig. 11 is a similar section when the pen is pushed out. Fig. l2 is a transverse section in the plane z e, Fig. 9. Fig. 13 is an inside elevation of the pen. Fig. 14 is a longitudinal centralsection ofA a portion of the holder in the plane o o', Fig. l2.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates the outside casing, which is open at both ends, and into the upper end of this casing is fitted' the hollow head C, from which extends a tube D down into a tube B, which is firmly secured in the lower end of the casing A. On the interior of the tube D is situated @seau misiones. (r invano' lower end of said sheath being split to form spring-jaws,:which are caused to grasp the lead by means of4 a cap E in the manner well known in the art. The tube D is firmly connected to the head C by a rivet or other suitable means, so that it is compelled to turn with said head, and also to move lengthwisewith the same. On the tube D is fit-ted a cam-sleeve d, the cam-surface of which bears upon a4 corresponding cam b, formed on the upper end of the tube B, and between the cam-sleeve d and the head C is placed a spring G, which has a tendency to force the head up to the position shown in Figs. l, 2, 9, andV l0. From the innersurface of the cam-sleeve CZ projects a key CZ into a slot d2, formed in the tube D, so that when this tube l is turned the cam-sleeve can be brought from the positionwhich it occupies in Fig. l

to that which it occupiesin Fig. 9. y

On the lower part of the tube D is formed a circular groove for the reception of the latch I, which'can turn freely in either direction,-

' gages a groove J, which is. formed in the invner surface of the tube B, Figs. v5, 6, 2,13, l0,r and 4, and the lower portion of which spreads andeXtends round a heart-shaped projection D moves down in the tube B, and as the tooth c' of the latch strikes the projection j at the point j', Fig. 6, the latch I is caused to turn, and the tooth z' finally strikes the depression` head C is released and permitted to follow the action of the spring G, the tooth 'L' passes into- -the depression e7'3 of the projection j, and the further upward movement of the tube VD is arrested. p the tooth c' of the latch I strikes the.dep`res,- sion ,7'4 inl the bottom of the groove J, and if .follow the action of the spring G the tube Dl rises to its original position. If the sheath E, which carries the lead F, is brought in engagement with the tube D and the head C is depressed and then released, so that the tooth 1I of the latch occupies the position js, Figs. 6 and 3, the sheath E is retained in the position shown in 3, and the lead can be used for writing, and if the pen P is thrown in enthe head C is then released and permitted to`- the sheath E, which contains the lead F, the

and from which projects a tooth vl, which enf When the head C is depressed, the tube L7'2 at the bottom end of the groove J. If the- If the head C is again depressed,

IOC

gagement with the tube D and the head C is depressed and then released, so that the tooth t' of the latch occupies the position j3, Figs. 6 and l1, the pen P is retained in its forward position ready for use. By depressing the head C a second time and then releasing it the lead or the pen is retracted.

For the purpose of throwing the sheath E, which carries the lead F, in engagement with the tubeD, said sheath is provided with a toe e, which extends through the tube D and into the tube B, and in order to permit this toe to pass the slot d2 in the tube D is provided with a lateral branch cl3, (best seen in Fig. 7

and the tube B is provided with a slot b?, Fig. 5, which also has a lateral branch b3. If the tube D,- with its cam d, is adjusted in the position shown in Figs. l, 2, and 3, the lateral branch da of vthe slot d2 in said tube catches over the toe e of the sheath E. (Best seen in Fig; 7.-) If the head C is new depressed and released, the lead F is brought into the position vshown in Fig.` 3, and retained there ready for use and if the head C is again depressed and then released the lead F is retracted, as already explained, During these operations the toe e moves up and down in iheslot b2 of the tube B.

For the purpose of putting the pen' P in engagement with the tube D, said pen is provided with a toe p, (best seen in Figs. 1l and 13;) and if the peli is adjusted in the holder its toe p extends through a slot b5 in the tube B and into the slot cl2 of the ltube D, which is provided with an additional' lateral branch d4. (Best seen in Fig. 7.) This'branch 'extendsin a direction opposite to that of the branch d3, and it is made narrower than the toe e of the sheath E, so that it cannot engage thlS/e; Y y

Then the holder is adjusted to operate the lead F, Figs. 1 2, and 3, the toe p of the pen is situated in line with the slot cl2 of the tube D, and if said tube is depressed the penremains stationary; but when the tube D is turned to the position shownin Figs. 9, 10, and 11 the toe -e of the sheath Eis thrown out of the lateral branch da and in line with the slot d?, While the toe 1J' of the .pen is thrown into the lateral branch d4, (see Fig. 9;) and if the head is lthen depressed and released the pen P is brought into the position shown in Fig. l1 and retained there ready for use; and if the head C is again depressed and released the pen is retracted,l while the lead F is not moved, since the toe e of the sheath E occupies a position in line with the slot cl2 in the tube D and engages the lateral branch b3 of the tube B.

In order to compel the sheath E to turn pliied, since a single cam-groove J has been substituted for double series of teeth, and this cam-groove can be produced at a single blow of a suitable die, so that I am enabled to manufacture my pen and pencil holde' at a suiiic'iently low price to renderthe saine accessible to the poor as well as to the rich;

rI do not claim in this application anything shown and described in my patent, No. 387,042, heretofore referred to; Y

What I claim as new, and desire to secure by Letters Patent, is-e l, The combination, with the 4casing A, spring-actuated head C, inovablytted into said casin g, and the tube D, secured to the head C, of the latch I, carried by the tube D, and the tube B, secured in the casing A and provided with the cam-groove J, which is made to extend round its heart-shaped projectionj, substantially as described. Y p

2. Ina pen and pencil holder, the combination, with the casing A, the spring-actuated head C, movably fitted into said casing, and

the tube D, secured to the head C, of the latch I, carried by the tube D, the tube B, secured in the casing A and provided with the camgroov'e J, a sheath E, a pen P, and mechanism,

substantially as herein described, for throw- I ing either the sheath E or the pen P in engagement with the tube D. p

3. In a pen and pencil holder, the com'biiiafV tion of the casing A, the spring-actuated head C, movably fitted into' said casing, the tube D, Secured to the head C and providediwith a longitudinal slot d?, having lateral branches' d3 d4, the lead-sheath E, having a toe e, the pen P, having a toe p, the latch I, 'carried by the tube D, the tube B, secured in the casing A and provided with the cam-groove J, and

the cams b d, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
