Application led November a, 1922. Seal No. 599,096.

To all whom t may concern.'

Be it known that I, ALBERT L. DETRIGK, a citizen of the United States, residing at Jersey City, in the county of Hudson and State ofn New Jersey, have invented new and useful Improvements in Writing Instrumentalities, of which the following is a specification.

This invention relates to writing instrumentalities.

Some of the objects o f the present invention are: to produce a writing instrumentality comprising a pen and a pencil and in which the pen and the pencil embody features which coact for feedin or extending the lead of the pencil and- W ich allow the pen and pencil to be separated; to provide means allowing the pencil to have either end thereof inserted into the hollow end of the pen-holder so that the pencil may have a holder or staff of proper length when used for writing, and so that the writing end of the pencil may be covered when not in use;

and with these and other objects in view, the invention resides in the particular provision, construction andfunctions of the .A lead pusher 21 is place parts hereinafter fully described and illus- ,y trated in the accompanying drawing, in'


Figure 1 isa longitudinal central sectional view of the instrumentality.

Figure 2 is a transverse sectional View taken on the line 2 2, Figure 1, enlarged.

Figure 3 is a transverse sectional view taken on the line 3 3, Figure 1, enlarged. Y Figure 4 is a perspective view of the'head forming a partof the pencil which carries the lead pusher guides.

Referring now more particularly to the several views of the drawing, it will be apparent that the writing instrumentality of the present invention, is made up of a pen 1() and a pencil 11, and means which constitutes the salient feature of the invention for allowing the pencil to be supported by one end of the pen; to allow the pencil to be supported for writing and to be supported with its writing end covered; and to eifect the extension or projection of the lead of the pencil.

The mentioned means includes the hollow end 12 of the pen-holder 13 which also embodies the barrel of the pen; a barrel bein used because the pen is a fountain en and it therefore has a cap which covers t e writing nib when the pen is not in use. In-

teriorly of the hollow end" 12 there are grooves 14 which extend longitudinally, and which are opposite each other. A barrel 15 is employed. The barrel 15 is internally screw threaded as at 16; it has a bore 17 1n one end thereof through which the stick writing lead is projected or fed; a knurled manipulating ring 18; and portions on opposite sides of the ring 18 which are equal infdiameter so that either end of the barrel 15 will fit in thehollow end 12. A head 19 is employed and this head carries s aced guides 20 which are disposed interior y of the barrel 15 in the assembla e of the parts. between `the guides 20, and the opposite ends'iof the-lead pusher are milled to provide teeth or threads 22 capable of screw threading action with the screw threads 16. The head 19 has portions 23 so arranged as to be capable of being received in the grooves 14. It will now be manifest that when the end of the pencil having the head 19 is disposed in the hollow end of the pen-holder 13, and by reason of the portions 23 of the head being disposed in the grooves 14, the head 19 and therefore the guides 2() will be held against turning movement relatively to the said pen-holder 13.

-The lead pusher 21 being arranged between the guides 20 will only be allowed to be moved back and forth. ELUpon the turning of the barrel 15, the-lead pusher may be advanced'or it may be brought back at will.

It should therefore be understood that leadl 24 may be projected the ydesired degree throughthe bore 17 simply by turning the barrel 15. It should also be manifest that the pencil in its entirety may beseparated from thepen and that the writing end of the pencil may be inserted into the hollow end 12. When the pen is to .be used, the cap thereof may be readily placed on the exposed end of the pencil.

What is claimed is:

i 1. A writing instrumentality comprising a pen-holder having a hollow end, a pencil having a head at one end which is insertable into said hollow end, means embodied by said hollow end and said head for holding said head against turnin spaced guides carried by said head, a lea pusher movable between said guides, a barrel ca able of being turnably carried by said ho ow end, and means between the barrel an'd the leed usher for eecting the movement of said ead pusher.


2. ln a device of the class described, the combination With a holder having a hollow recess, diametrically opposed grooves eX- tending the length of said recess, a pencil comprising a revolveble barrel, the inner Walls of seid barrel being threaded, e heed provided with longitudinal ribs for co-action with the said grooves, and a lead pusher co- Leoeee acting with the threads of seid barrel, and

guides carried by said head and disposed on il@ opposite sides of seid leed pusher, subtantially as and for the purpose specied.
