DRAWING-PEN.

SPECIFICATION forming part of Letters Patent No. 479,270, dated July 19, 1892.

Serial No. 431,145. (No model.)

To all whom it may concern:

Be it known that I, OscAR F. GRANT, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Drawing-Pens; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form part of this specification.

This invention relates to that class of drawing instruments generally designated as right-line or ruling pens; and the object of this invention is to provide a pen which can be readily filled with ink without soiling the fingers of the draftsman and which when filled does not require to have the surplus ink removed before using the pen.

This invention therefore consists in the production of a pen of a peculiar and novel construction whereby one of the blades of the pen can be utilized as a filler or inker. I

This invention further consists in the novel construction of a pen whereby one of the blades can be utilized as afiller or inker and also as a fountain for ink, whereby a large quantity of ink can be taken up and retained by the pen.

This invention still further consists in the novel construction, combination, and arrangement of parts more fully described hereinafter, and specifically pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a side View of my improved pen with the blades closed; Fig. 2, a like View with the blades open; Figs. 3 and 4, detail views,

v and Figs. 5 and 6 views of modifications.

A represents the handpiece, and B G the blades, of the pen. The blade B is attached to the handpiece in the ordinary way by being screwed therein or in any desired and suitable manner. The blade 0 is hinged to the blade B, as shown at D, and a fiat spring E, placed between the two blades above the hinge, serves to keep the points or nibs of the blades together, an adjusting-screw F regulating the distance between the points of the blades. may be, as shown in Fig. 3, concaved to form a fountain or reservoir for the ink, or one of The lower or nib ends of the blades the blades, as shown in Fig. 4, may be provided with a reservoir on the outside of the blade, the reservoir communicating with the inside of the pen by a suitable orifice formed in the bottom of the reservoir.

In practical operation of the device, when it is desired to fill the pen with ink the finger is pressed on the short end G of the blade 0 and the blades separated sufficiently at their points to permit the nib of the blade 0 to be dipped into the ink well or bottle, and a sufficient quantity of ink will adhere to the same to fill the pen, and as the point of the blade B is not placed in the ink it will remain clean and not require to have the surplus ink removed before using, as would be the case where both blades of the pen are put into the ink well or bottle, thus saving time and ink, as in the ordinary pen more ink is wasted in the operation of cleaning the pen than is used on actual work. If the pen is of either of the forms shown in Figs. 3 or t of the drawings, a sufficient quantity of ink will be taken up and retained in the reservoir to complete an ordinary drawing.

In the modifications as illustrated in Figs. 5 and 6 of the drawings the pen may be constructed of the ordinary and well-known form of drawing-pen having the handle A and the blades 15 and O and adjusting-screw F, the blade 13 being provided with a slot or orifice I), through which the ink is supplied to the points by means of an extra blade H, which is hinged at I to the blade 13 and is provided at its point with any suitable form of a reservoir J, which in the drawings is shown as a spiral; but any other suitable form of reservoir may be used. When the extra blade is closed, the reservoir J is directly over the opening I) in the blade B, so that the ink which is taken up by the same may enter through the slot, and thus supply the pen with a constant flow of ink during the time of its use.

It will be readily understood that in the form of feeder shown in Figs. 5 and 6 the point of the extra blade is the only portion of the pen that is placed in the ink, and that consequently the points of the pen itself are not only free from the surplus ink, but that they will remain in better condition than where the points are being constantly dipped into ICO the ink bottle or well and thereby worn away and roughened.

Having thus described my invention, what I claim as new, and desire to secure by Letters 5 Patent, is-

1. A drawingpen having two blades, one of said blades being hinged to the other and having an inkreservoir on its lower end, whereby ink may be taken from a receptacle 10 and conveyed to the stationary blade, substantially as described.

2. A drawing-pen provided with an auxiliary blade hinged to one of the blades of the pen, said auxiliary blade having an ink-re- I 5 cept-acle on its lower end, whereby ink may April, 1892.
