PEN.

Specification of Letters Patent.

Application filed January 29, 1909. Serial No. 474,919.

To all whom it may concern:

Be it known that I, HERBERT lV. KUEFF- man, a citizen of the United States, residing at Burlington, in the county of Alamance and State of North Carolina, have invented new and useful Improvements in Pens, of which the followin is a specification.

My invention r ates to improvements in ruling pens.

The primary object of the invention is the provision of a (pen of this character which shall be provi ed with a reservoir from which the ink shall flow on to the inner sides of the nibs of the pen and with a valve by means of which tie flow of ink to the pen nibs 'can be controlled.

A further object of the invention is the provision of a fountain ruling pen with means by which the ink in the reservoir may be kept under ressure at all times.

A still furtier object of the invention is the rovision of a fountain rulin pen which shal be simple, durable and eiiicient, and which may be manufactured and sold at a comparativel low cost.

With the a ove and other objects in view, the invention consists in the novel construction, combination, and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawing, wherein Figure 1 is a view in side elevation of a fountain ruling pen constructed in accordance with my invention. Fig. 2 is a top plan view thereof. Fig. 3 is a sectional view taken on a plane extending centrally and longitudinally through the pen. Fig. 4 is a detail view in side elevation of the valve of the pen. Fig. 5 is a sectional view taken on the horizontal lane indicated by the line 55 of Fig. 1, 100 ring in the direction indicated by the arrow.

Referring to the drawing by reference numerals, 1 designates the body of m improved fountain ruling pen. A air 0 relatively spaced nibs 2 are forme integrally with and project from one end of the body 1. The opposite end of the body 1 is provided with a circular socket 3 WlllCh has the inner side of its annular wall 4 screwthreaded. The body 1 is provided with an annular o ening 5 which opens at its ends out throng the ends of the body, the wall of said openin being screw-threaded. The nibs 2 may. relatively ad'usted and retained in adjusted positions y means of a set-screw 6 which is provided with a milled operating head 6 and which passes freely through one of the nibs and threadedly engages the other. The handle 7 of the pen is of hollow cylindrical formation, one end thereof bein closed while the other end thereof is fu ly open. At its 0 en end the handle 7 is provided with a re uced stud 8 which is externally threaded for engagement with the threaded wall 4 of the socket 3, said stud detachably securing the handle tothe body 1. A flexible reservoir 9 also of cylindrical formation, is removably mounted in the handle 7, one end of the reservoir being closed while the other end thereof is fully open. The open end of the reservoir 9 1s secured to the stud 8 by means of a hollow bushing 10, the bushing clamping the end of.the reservoir between its outer inclined side and the inner inclined side of the stud.

The free end of the reservoir is also clamped between the end of the stud 8 and the bottom wall of the recess 3. The opening in the bushing 10 registers with the opening 5' in the body 1.

The ink is conveyed from the reservoir 9 on to the inner sides of the nibs 2 by means of a rigid feed tube ll'which is located between the nibs and which is provided with a reduced discharge end 12 having its discharge openin 13 located in close proximity to the ends 0 the nibs. The opposite end of the feed tube has threaded engagement with the opening 5 of the body 1, and the discharge end 12 is detachably secured to one of the nibs 2 by means of a lug 14 fitting in a lug 15 formed on the inner side of said nib. The discharge of the ink from the tube 11 on to the nibs 2 is under the control of a valve 16 which comprises a fiat body 17 which is slidably mounted in openings 18 formed in the feed tube and in an opening 19 formed in one of the nibs 2, the thickness of the feed tube being increased about one of the openings 18. The valve 16 also comprises a stem 20 which passes through an opening 21 formed in the other nib 2, and a head 22 which is mounted in a socket 23 formed in and opening out through the inner side of said nib. The valve 16 is provided at a point adjacent one of the ends of its body 17 with an opening 24 which when it registers with the passa e of the tube 11 allows ink to flow on to the nibs 2. When the opening is in this position the valve is opened. The opening 24 is Patented Apr. 5, 1910.

normally retained out of registration with the passage of the feed tube 11, that is to say, the valve is normally retained closed by means of an expansiblecoiled spring 25 which is mounted in a casing 25. The casing has one end fully open for the reception of the head 22 of the valve stem v20, the spring being located between the closed end of the casing and the head.. The casing 25 is suitably secured in the socket 23 of one of the pen nibs 2. When the valve 16 is closed the stem 20 projects above the nib 2 through which it passes whereby to enable it to be engaged when it is desired to open the valve. The valve is arranged in such relation to the set-screw 6 that the stem 20 is within convenient reach.

The ink in the reservoir maybe retained under pressure at all times to insure itsproper feed to the nibs 2, through the medium of a pressure plate 26 which is located in the handle 7 outside of the reservoir and which is carried by and under the control of a feed-screw 27. The feed-screw 27 has threaded engagement with the handle 7 and it is provided with a milled operating head 28. The several parts of my improved fountain pen may be made of any suitable materials and the weights of the parts are such that the pen is well balanced.

It should be apparent from the above description, taken in connection with the accompanying drawing, that I provide a fountain ruling pen which is simple, durable and eflicient, and which may be manufactured and sold at a comparatively low ,cost. It should also be apparent that a body carrying an ordinary writing nib may be substituted for the body 1 which carries ruling nibs 2.

While I have described the method of operation of the invention, together with the apparatus which I now consider to be the best embodiment-thereof, I desire to have it understood that the apparatus shown is merely illustrative and that such changes may be made when desired as are within the scope of the claims.

Having thus described the invention, what is claimed as new is 1. A pen comprising a body, nibs projecting from one side of the body, a reservoir secured to the opposite side of the body, a feed tube located between the nibs and communicating with the reservoir, a valve'slidably mounted in the feed tube, said valve being provided with a stem passing through one of the nibs, and a spring adapted to retain the valve normally closed.

2. A pen comprising a body, nibsprojecting from one side of the body, a set-screw carried by the nibs, a reservoir secured to the opposite side of.the body, a feed tube located between the nibs and communicating with the reservoir, a valve slidably mounted in the feed tube, said valve being provided with a stem passing through one of the nibs at a point adjacent the operating head of said screw, and a spring adapted to retain the valve normall closed.

3. A pen comprising a body, nibsprojecting from' one side of the body, a reservoir secured to the oppositeside of the body, a feed tube located between the nibs and communicating with the reservoir, a valve slidably mounted in the feed tube and provided with a stem passing through one of the nibs, a casing secured to the nib through which the stem passes, the stem passing through said casing, a head secured to the stem, and an expansible coiled spring mounted between the head and one wall of the casingand adapted to normally retain the valve closed.

4:. A pen comprising a body, nibs projecting from one end of the body, the opposite end of the body being provided with a circular-socket having its annular wall screw threaded, the body being provided with a passage opening at its ends out through the
