FOUNTAIN DRAWlNG OR RULING PEN.

SPECIFICATION forming part of Letters Patent No. 727,433, dated May 5, 1903. Application filed July 29, 1902. Serial No. 117,530. (No model.)

Z'o all whom, 7125 11mg/ concern: v

Be it known that I, WALTER CLiNToN PET- TEE, a citizen ofthe United States, and a resident ofthe city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Fountain Drawing or Ruling Ien, of which the following is a full, clear, and exact description.

The invention relates to drawing instruments; and its object is to provide a new and improved drawing or ruling pen which is simple and durable in construction and arranged to supply ink to the pen-points without the ink unduly drying up, and permitting vconvenient setting, filling, and cleaning whenever desired.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of-the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a side elevation of the improvement. Fig.l 2 is a sectional side elevation of the same. Fig. 3 is a sectional plan view of the same on the line 3 3 of Fig. l, and Fig. et is a similar view of the same on the line 4 4 of Fig. l.

The pen-points A and A', of spring-steel, have their Shanks A2 and A3 removably secured to opposite sides of an ink-reservoir B for containing liquid ink to be supplied to the pen-points at their inner faces and in close proximity to the terminalsv thereof, and for this purpose the tubular reservoir B is provided with a tubular tapering end B', extending between, but free of, the pen-points A and A', as plainly shown in the drawings, the outlet of the said tapering end being split transversely to form members B2 B3, curved outwardly in opposite directions toward the inner iiat faces of the pen-points A and A', as plainly indicated in Fig. 2, to contact with the said faces of the pen-points to insure a ready low of ink from the reservoir B equally to both pen-points A and A'.

In order to set the pen-points A and A' for heavier or liner lines, a handle C is provided inclosin g the reservoir B and held lengthwise adjustable relative to the reservoir and the pen-points. The lower end of the handle C is for the purpose mentioned arranged to engage inclines or bevels A4 and A5, formed on the pen-points adjacent to the Shanks A2 A3, so that when the handle is moved downward this lower end engages the said inclines or bevels A4 A5 to press the pen-points toward each other for reducing the space between the terminals of the pen-points to set the same for drawing finer lines. When the handle C is shifted upward, then the inherent resiliency of the pen-points A and A' causes the same to open to increase the space between the terminalsfthus setting the penpoints for heavier lines.

In order to shift the handle C lengthwise relative to the pen-points, various means may be employed. For instance, the upper end of the handle C may be provided with bearings C' for engaging the peripheral face of a nut D, screwing on the upper threaded end B4 of the reservoir B. Now when the operator turns the nut D in one direction to screw the nut downward on the reservoir B then it carries the handle C along to cause the latter to act on the inclines or bevels A4 A5 to close the pen-points, as previously explained, and when the nut D is turned in the opposite direction to screw the same upward on the threaded end B4 then the handle C is moved in a like direction and the pen-points A and A' are free to open by their own resiliency.

In order to clean the lower contracted outlet of the end B', I provide a needle E, eX- tending lengthwise in the reservoir B and passing through the upper closed end thereof to support a knob E', adapted to be taken hold of by the operator to push the needle in 1 and out of the outlet to clean the same when ever necessary. The needle E also carries a piston F within the reservoir B, so as to draw the ink into the reservoir when moving the knob E' outward at the time the end B' is inserted in ink to be illed into the reservoir.

I do not limit myself to the particular construction described, as the same may be varied without deviating from the spirit of my invention.

Having thus described my invention, I

l. A drawing or ruling pen, comprising a reservoir for ink having a reduced tubular end, pen-points between which the said endV of the reservoir extends, and means for adjusting the pen-points, as set forth.

2. A drawing or ruling pen provided with pen-points, and a reservoirv having a reduced tapering end formed with a split, to produce two members curved outwardly toward the inner faces of the pen-points, as set forth.

3. A fountain drawing or ruling pen, comprising a reservoir for ink and provided with a tapering outlet, pen-points secured on the reservoir and projecting therefrom, free and outside of the said outlet of the reservoir, and means for adjusting the pen-points for drawing heavier or lighterlines, as set forth.

4. A fountain drawing or ruling pen, comprising a reservoir for ink and provided with a tapering outlet, pen-points secured on the reservoir and projecting therefrom, free and outside of the said outlet, the said pen-points being formed with bevels, an adjusting device for the pen-points, consisting of a tubular handle for inclosing the reservoir and engaging the bevels on the penpoints, and means for shifting the handle lengthwise, relative to the pen-points and reservoir, set forth.

5. A fountain drawing or ruling pen, comprising a reservoir for ink and provided with side of the tapering outlet, and a manuallycontrolled piston in the said reservoir, as set forth.

7. A fountain drawing or ruling pen, comprising a reservoir for ink and having one end formed into a tapering outlet and the other end threaded, pen-points secured on the reservoir and projecting therefrom, free and outside ofthe said outlet, said pen-points having hevels, a handle inclosing the said reservoir and engaging with one end the said bevels, thehandle being provided at the other end with bearings, and a nut screwing on the threaded end of the reservoir and held in the said hearings, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WALTER CLINTON PE'ITEE.
