IEEN' PENCIL.

Application filed February 8, 1926. Serial No. 86,873.

This invention, relating as indicated to a combination pen and pencil, refers more particularly to an lII'lPl'OV-OCl article of that class wherein the ink containing reservoir is of the self-filling type, and the pencil of the expulsion type. An object ofthe invention is to provide novel means for both effecting the control of the lead and for compressing the ink containing reservoir. Another object of the invention is to provide a combined pen and pencil which issimplc in construction and inexpensive in manufacture.

To the accomplishment of the foregoing and related ends, saidinvention, then consists of the means'hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mecha nism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principl of the invention ma be used.-

In said annexed rawing:

Fig. 1 is an elevational view of the present novel device; Fig. 2 is a central longitudinal section through the same; and Figs. 3 and 4 are sectional views taken on lines 3-3 and H of Fig. 2 respectively. I

The illustrated embodiment of my invention consists of a cylindrical tube constructed of two parts and 11 secured together at their adjacent edges by a cylindrical spacer 12. This spacer 12 has provided at its ends threads 13 and 14 which engage respectively with internal threads 15 and 16 011 the adjacent ends of sections 10 and 11. Positioned at the outer end of section 10 is a fountain pen 17 which may be of any conventional feed piece 18 are secured in the bore of said bushing 21. The other end of the device may also beprovided with threads 23 to which the cap may be secured when the device is being used as a fountain pen. in this cap member 20, in a recess at its outer end 24-, is provided an eraser 25.

To the inner reduced end of the bushing 21 within the section 10 is secured the open end 26 of an ink containing sack or reservoir 27, the same being here. shown as a compressible corrugated rubber member which may be compressed longitudinally by pressure applied to its closed end 28. In the filling operation of the present device certain mechanism, as will appear hereinafter, is provided to exert a longitudinal pressure on the end 28 whereby the air is exhausted from the ink containing sack 27. When such pressure is relieved the inherent resilience of the sack 27 will tend to restore the same to its normal extended position and thus draw in a supply of ink through the usual hole at the outer end of the pen 17 and through the hole 19.

As stated, the section 11 of the present combined pen and pencil device carries at its outer end, certain mechanism for containing and feeding pencil lead. This end 30, shown in Fig. 2, is formed conical and has a central longitudinal opening 81 therethrough which is of proper size to accommodate a pencil lead 32. Permanently secured to the end 30 of section 11 is an inwardly extending cylindrical tube 33 which serves is an inp nor support and guide for the lead as well as a guide for the lead propelling mechanism. A spacer 34 may be employed between such tube 33 and the inner periphery of thecy-lindrical section 11 to strengthen the entire. lcad containing structure.

As will be seen from an inspection of Fig. 2, the cylindrical spacer 12 is of sutticient length to provide an annular space at its outer surface between the respective ends of sections 10 and 11 when secured to said two latter members. I propose to mount in such space a revolvable sleeve 37 which is confined from longitudinal movement by engagement with the ends of sections 10 and 11. On the interior of this sleeve 37 are provided screw one leg 40 of a U-shaped member 41 which is utilized both to expel the lead through the tube 33. and to compress the ink containing sack 27. The leg 40 has provided at its outer surface, rack teeth 42 which engage with the internal threads 38 of the revoluble sleeve 37. Itwill be obvious that any rotation given to the sleeve 37 will impart reciprocatory movement to the U-shaped member 41.

facilitate the manual operation thereof.

The connecting portion 43 of the U-shaped member 41 is positioned adjacent the end 28 er projection 47 fitting within the interior of,

of the ink sack and has a projecting lug 44 thereon disposed centrally of the interior of section 10 adapted to contact with a disc 45 slidably mounted withinthe section 10 at the closed end of the sack.

, The other end or leg 46 of the U-shaped member 41 is extended parallel with the leg 40 and is reduced in size to provide a plunge the tube 33. This plunger end 47 is adapted to engage with the inner end of the lead 32 and as the member 41 is moved to the left of Fig. 2 through actuation of the sleeve 37, such plunger will force'the lead through the outer conical end 30. I

It will be apparent from the foregoing that I have accomplished the objects primarily stated and that I have provided a new and improved combined pen and pencil which is simple in operation and which may be inexpensively manufactured and assembled. The mechanism provided for ejecting the pencil lead is'so designed that it may be utilized for compressing the ink containing sack; I am aware that there are many patents relating to combined pen/and pencil devices. but in none of them is found the improved feature of providing a single .mechanism which is adapted -to serve both as a self-filling device for the ink reservoir and as means for expelling the pencil lead, b

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

'I therefore particularly point out and distinctly claim as my invention 1. A device of the character described comprising a two-part cylindrical tube, a spacer securing said parts together, a fountain pen in the outer end of one part, a lead guide in the outer end of the other part, a compressible ink sack mounted within said tube and The outer surface of the sleeve 37 may be knurledto connected to said pen, a rotatable sleeve mounted on said tube, and connections actuated from the rotation of said sleeve for compressing saidsack and for expelling lead through said guide.

' 2. A device of the character described com-- prising a two-part cylindrical tube, means for securing the adjacent ends of said parts in spaced relation,-a lead guide mountedin one of said parts, a fountain pen mounted in the other part, an ink sack connected to said pen, machanism for expelling lead from said guide, and means mounted between the ends of said cylindrical parts for actuating said mechanism and for compressing said sack.
