JOI-IN F. REEVE, OF RICHMOND, VIRGINIA.

WRITING-PEN.

Specification of Letters Patent No. 16,496, dated January 27, 1857.

To all whom it may concern:

Be it known that I, JOHN F. REEVE, of the city of Richmond, county of Henrico, and State of Virginia, have invented certain new and useful Improvements in friting-Pens; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.

My invention consists in so jointing together two strips of rigid metal, glass, porcelain, or o-ther similar substances so as to form a writing pen, the point of which isy caused to open and close, for making line or coarse lines, not by the yielding and recoil of elastic material, resulting from the greater or less pressure of the point on the paper as in ordinary pens, but by the greater or less pressure on the point so acting upon the two rigid halves of the pen that with the aid of a wedge and spring, or equivalent. devices, the said two halves may so turn laterally at their joint that the point of the pen may open and close. Pens thus made are not only much more durable than those of ordinary construction, but they are also capable of producing the very linest lines with even greater accuracy than common metallic pens, and at the same time possess, in the hands of the writer all the freedom and boldness common to quill pens. In conjunction with the jointed halves of the pen I employ a regulating spring (fully described hereafter) by means of which the pen may be readily made hard or soft at pleasure.

In order to enable others skilled in the art to make and use my invention I will now proceed to describe its construct-ion and operation.

On reference to the drawing which forms a part of this specification. Figure l is a longitudinal section of my improved writing pen, on the line 3, et (Fig. 2). Fig. 2 a plan of the same showing the point of the pen closed, and the sliding tube in section. Fig. 3 the same as Fig. 2, but with the point of the pen open. Fig. 4 a transverse section on the line l, 2 (Figs. l and 2).

All the views are drawn to a scale of three times the actual size, and the same letters of reference allude to similar parts throughout the several views.

The handle A and ferrule form the holder of the pen. To the projecting portion ZJ of the ferrule is jointed a lug a on the top of which is a pin e the latter passing through the two halves c and c and so riveted as to hinge them together. To the projecting portion of the ferrule is also secured a wedge shaped piece It, (see Fig. 6) against the inclined sides of which bear the ends of the arins c and c of the two halves C and C of the pen; the ends of the arms also bear on one end of the spring D, the opposite end of which is secured to the stem A in any convenient manner. A steel or gum elastic spring E serves to keep the two arms c and c, and consequently the point of the pen closed; this spring is arranged to slide backward and forward along the arms.

Secured to one half only of the pin but in contact with the other half is a strip f which, together with the orifice formed by the notches x, zr, serves to retain a large body of ink on the pen.

In writing pens the opening and closing of the points has been hitherto effected by the elasticity of the material of which they are composed, together with the greater or less pressure of the point on the paper; the material of which the pens are composed being thus submitted to a continuous strain becomes rapidly deteriorated and the pens rendered useless. In my improved pen which is composed of rigid or non-elast-c material the required opening and closing of the point is effected as follows. On pressing the point hard on the paper the two halves of the pen will simultaneously turn on the pin which passes through the lug a, the point of the pen being raised and the arms c and c depressed, at the same time the ends of the arms acting upon the inclined sides of thel wedge shaped piece 71., the two halves of the pen must necessarily turn on the pin e and consequently the arms 0 and c as wel] as the points of the pen will open, (see Fig. 3) and this to an amount commensurate with the degree of pressure employed. Then the pressure ceases the spring I) raises the arms c and c until their the pen is much more durable than any of the ordinary pens and can be handled with as much freedom as common quill pens.

The amount of pressure required for the opening and closing of the point may be regulated by sliding the spring E backward or forward along the arms c and c; when the spring is close to the joint as in Fig. 3 comparatively little pressure is required to cause the required opening, but when near the ends of the arms as in Fig. 2, a greater pressure is required, and thus the pen may be readily made hard or soft to suit the convenience of the writer. G is a plain or ornamented metal tube arranged to slide over the ferrule B so that the arms c and c with the sliding spring E and wedge-shaped piece h may be covered or exposed at pleasure.

Although I have shown a peculiar arrangement of joints, springs, and wedge, I do not desire to coni-ine myself to the precise form or disposal of the several parts, as

the same may be considerably modified without altering the result, but

IVhat I claim and desire to secure by Letters Patent isl. The so jointing together of the two pieces c and c of rigid or nonelastic metal or other material that the same may form a pen the required opening and closing of the point of which may be effected by the greater or less pressure of the said point on the paper, assisted by the within described springs and wedge, or equivalent devices.

2. The regulating spring E as applied to the arms c and 0 in the manner and for the purpose herein set forth.

In testimony whereof I have signed my name to this specification before two subscribing witnesses.

JOHN F. REEVE.
