RESERVOIR PEN Filed Dec. 29. 1932 2 Sheets-Sheet 2 Patented June 5, 1934 RESERVOIR PEN Herbert Weld, London, England Application December 29, 1932, Serial No. 649,261 In Great Britain December 30, 1931 2 Claims.

This invention relates to improvements in reservoir pens. Reservoir or fountain pens as heretofore proposed have been fairly satisfactory but the supply of ink in the same is not sufficient if 5 a large amount of writing has to be done. Also,

fountain pens will not always write when required to do so, and the user has then to shake the same to cause the ink to flow. All these disadvantages are overcome by means of the present invention which provides a reservoir pen which can be used for great lengths of time without refilling, which can be easily handled, and in which furthermore the rate of flow of inl: to the nib may be adjusted to suit the speed at which any individual person writes.

According to the present invention, the reservoir pen comprises a standard supporting a reservoir which is connected by flexible tubing to the pen, a needle valve or other like device being provided by means of which the rate of flow of the ink from the reservoir to the pen may be adjusted.

The said standard may be flexible to prevent any strain being put on the flexible tubing.

It has heretofore been proposed to provide a reservoir pen in which the pen itself is connected by means of a flexible capilliary tube to a reservoir containing a large supply of ink, the flow of the ink along the flexible capilliary tube being controlled by means of a spring clip which may be provided on the pen, reservoir or tube for the purpose of stopping the flow of ink when desired. As distinct from this prior proposal, the valve of the present invention provides means for control- 35 ling the rate of ow of the ink from the reservoir to the pen.

In order that this invention may be the more clearly understood and readily carried into effect, I will proceed to describe the same with reference to the accompanying drawings, which illustrate by way of example and not of limitation one convenient form of this invention, and in which Figure l is a perspective view of the complete device.

45 Figure 2 is a sectional View through the upper end of the standard and the reservoir.

Figure 3 is a sectional view through the base,

Figure 4 is a sectional view through the pen, and

Figure 5 is an elevation of the reservoir detached from the standard.

Referring now to the drawings, the device comprises a base a from which projects a standard b made of wire coiled into the form of a tube in the known manner. The standard is thus ilexibleV (see Figure 1) but at the same time suiiiciently rigid for the purpose in View. The flexible tubular standard b may be secured in the base a in any suitable manner, but I prefer to mount the same by providing in the base a screw-threaded hole al, the pitch of the thread of which is equal to the pitch of the wire spiral forming the standard b, and the diameter of which is slightly less than the diameter of the standard. The lower end of the flexible standard is then screwed into this hole, and this may be easily accomplished by turning the end of the wire spiral diametrically across the end o the spiral, as at b1, and gripping'this end in a slot in the end of a rod. The spiral may then be tightened and easily screwed into position. The upper end of the standard supports the reservoir which comprises a tube c closed at the bottom with the exception of an outlet tube c1 and closed at the top by a screwed cap c2 carrying a needle valve c3 75* adapted to co-act with the upper end of the out let tube c4 to regulate the rate of now of ink from the reservoir.

The reservoir is mounted at the upper end of the standard b by means of a pin d which slips into the upper end thereof. This pin, which lies parallel with the axis of the reservoir but off-set therefrom, may be mounted on the reservoir in any suitable manner, preferably by means of a metal band e surrounding the reservoir which is secured to the pin d in any suitable manner.

The outlet tube oi the reservoir is connected to the upper end of the pen g by a length of ilexible rubber tubing f which may, ii' desired, be reinforced by means of a spiral of wire f1 surround- 90' ing the saine, partly or wholly. Inside the pen g, which may be of the usual shape, is a tube h from which the ink is fed to the nib through a iine hole h1. The upper end of the tube projects above the end of the pen in order that the rubber tube may be attached thereto.

When not in use, the p-en is placed nib downwards in a tubular or conical holder 7' for the same on the base a.

The reservoir will hold considerably more ink than the usual fountain pen and so the pen according to this invention may be used continuously for long periods. Also it has the advantage, not present in ordinary fountain pens, that the flow of ink may be adjusted to suit the speed at which any person writes.

1. A combined standard and ink reservoir for supplying a reservoir pen, comprising a length of closely coiled spiral Wire forming a eXible hol- 11'0 low standard, a base having therein a screwthreaded aperture to receive the lower coils of the standard to support the saine on the base, an ink reservoir, a control Valve to control the oW of ink from said reservoir, a pin off-set from the ink reservoir to take into the upper end of the Wire spiral to support the reservoir thereon and a rigid rod of less length than the flexible standard inside said spiral to limit the flexibility to the upper part of the standard.
