PEN-HOLDER.

' SPECIFICATION forming partlof Letters Patent No. 294,478, dated March 4, 1884. Application filed January 16,1884. (Nomodeh) To all whom it may concern/.- I Be it known that I, FREDERICK M. LIBBY, of Portland, in the county of Cumberland and State of Maine,'have invented certain new and useful Improvements in PenHolders and I do hereby declare that the followingis a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, refer ence being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 isaside sectional view of a penstock with my device inserted therein. Fig. 2 is a perspective view of a part of Fig. 1.

Same letters show like parts.

My invention relates to pen-holders in penstocks. It is intended to impart elasticity or a yielding property to the pen when it is pressed upon the paper in writing. This quality of yielding affords greatrelief to the fingers and wrist in writing, and prevents much of the fatigue and pain consequent upon the use for a long time of a pen that is stiii' and rigid in the holder and stock. The pen, when placed in my holder, has aslight tipping or vibrating motion when pressed on the paper, and so rethenrby the pressure of the nib of the pen' on the paper in writing. Being elastic, the wings yield, and so imparting a slight give or tipping to the nib of the pen, afford great relief to the fingers, hand, and wrist, especially in prolonged writing. Different degrees of elasticity can be imparted to the pen by the length and stiffness of the wings I) b.

The structure of the tube is clearly seen in the drawings. It is a sheet of metal rolled up into the proper size and form and furnished with wings or springs b b. This is then inserted into the hollow end of a pen-stock. Any pen-stock so constructed as to admit of its insertion can be' used to receive it. The

tube can be secured in place by rivets enter-- ing through the walls of the hollow end of the pen-stock and penetrating the tube, or in any well-known manner. The pen is inserted into the annular space between the outerperiphery of the tube and the inner periphery of the hollow of the penstock.

What I claim as my invention, and desire to secure by Letters Patent of the United States,

The tube at, having wings or springs 12 b,
