EDWARD BAPTIS, OF HUDSON, NEW JERSEY.

PEN AND PENCIL CASE.

Specication forming part of Letters Patent No. 17,776, dated July 14, 1857.

To all whom t may concern:

Be it known that I, EDWARD BAPTIs, of Hudson, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Pen and Pencil Cases; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, making a part of specification, said drawing being a longitudinal section of the external shell or tube of the case and showing my improvement.

This invention relates solely to an improvement on a pen and pencil case formerly patented by me and bearing,r date of April .29, 1856. In the patented case referred to two tubes were used, one placed within the other, said tubes having spiral grooves made or formed in them, one in each, the two grooves being in reverse positions, or one a right and the other a left hand groove. These spiral grooves, when the tubes were turned, shoved the pen and pencil or drew them within the case according to the direction in w lich the tubes were turned, the pen and pencil mov-A ing simultaneously in opposite directions.

The invention has for its object the reducing of the size of the case as regards its thickness or diameter, rendering it much more portable, and also adding greatly to its ap pearance.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the external shell or tube, which may be constructed in any of the wellknown forms. Within the shell or tube A an inner tube B is secured. The tube B is not equal in length to the shell or tube A- that is, when the tube A is extended-for the tube A is provided with a sliding or extension part a at the end opposite to that whence the pen and pencil are moved out.

The tube A is formed of two parts b c, the extension-slide et being fitted on the part Zi Y The tube B is so arranged that it may turn within the tube A, and the partb of the tube is attached to it, so that if the part c is held with one hand the inner tubeB may be turned `.by turning the part b.

The tube B has two spiral grooves cl e vcut in it.. These grooves are equal in length and extend from the ends to the center of the tube. The groove e is out entirely through the tube B, but the other groove d is not cut through.

Within the tube B a tube C is placed, and the tube C has the pencil-tube C fitted within it, and between the outer part of the tube B` and the tube A the pen-slide D is placed. The pen-slidehas a pin f attached to 1t, said pin being fitted in the groove d. The pencil tube has a pin g attached, which pin lits in thc groove c.

By referring to the drawing it will be seen that the spiral groove d'diminishes in pitch as it approaches the center of the tube and the inner turns of the groove are very much p slower than the outer ones. The same may be Said of the outer portion of the thread e at the end of the tube. much slower pitch than toward the center of the tube. This peculiarity in the spiral grooves constitutes the invention.

It will ,be seenl that by turning the tube B the pen-slide and pencil-tube are moved simultaneously, and as the grooves d e are in reverse positions, one being a right and the other a left hand thread, they will be moved in opposite directions, one being drawn within the `case as the other is being shoved out. In pencil-cases for desk or counting-house use all that would be required would be to have the spiral grooves of an equal pitch and have the tube suiciently long, so that the pen and pencil may be drawn alternately within the case. In this arrangement, however, both pen and pencil could not be drawn within the case at the same time, and the implement could not be advantageously carried in the pocket. In the case formerly patented by me the grooves were cut in separate tubes, one

Y tube placed within the other, and these tubes were made sufficiently long to allow the pen to be withdrawn within the case before the pencil was forced out, and vice versa. By this arrangement quite. long tubes were necessary, and as 'each groove was formed in a separate tube and-one tube placed within the other, the case was quite large and cumberf some. In order, therefore, to remedy this difliculty, I gradually decrease the pitch o the grooves CZ e, as shown, so that suficien time will be allowed to draw in the pen b( fore the pencil is shoved out, and vice versa By this improvement I am enabled to pla-r Atthis point it has a the two spiral grooves in line one back of the other, instead of using separate tubesand placing one Within the other. Inthe latter arrangement, formerly patented, as already alluded to, the case is necessarily quite thick, and decidedly too thick to be carried conveniently in the pocket.

By my improvement the case is not. longer than usual and may be made quite small in diameter, as small as would be desirable.

I do not claim the employment or use of two spiral grooves placed in reverse positions or one having a right and the other a left wave thread and so arranged as to operate simultaneously the pen and pencil slides, for spiral grooves have been previously used for this purpose; but

I claim- The employment or use of such grooves when made with a varying pitch, substantially as described, for the purpose set forth.
