PENHOLDER.

SPECIFICATION forming part of Letters Patent N 0. 630,133, dated August 1, 1899. Application filed August 5, 1898. Serial No. 687,859. (No model.)

To all w/tom it may concern:

Be it known that 1, WILLIAM THURMAN, of Denton, in the county of Benton and State of Texas, have invented a new and useful Improvement in Penholders,of which the follow ing is a full, clear, and exact description.

The object of the invention is to so construct the penholder that the pen may be adjusted to and from the outer end of the holder,whereby the pen is located in a spring controlled plunger arranged for free end movement within the casing or body of the holder and likewise for endwise adjustment.

A further object of the invention is to so construct the penholder that it will allow freedom of movement to the thumb and fingers, obviating cramping or tiring of the hand of the writer.

Another object of the invention is to secure a uniformly light touch of the pen on the paper, except where a heavy stroke is desired, and to prevent the pen from sticking or hanging in the paper, enabling one to write easily and evenly upon paper of inferior quality.

Another object of the invention is by the use of the improved penholder to obtain a smoothness in writing, even under unfavor able conditions, which is not attainable by the ordinary pen and penholder.

Another object of the invention is to provide a free moving support for the pen that will largely overcome the irregularities in the movement of the hand of a writer,malcing the correct formation of letters comparatively easy.

The improved construction of penholder facilitates speed in writing and is adapted for arm movement, finger movement, or a combination of the two.

The improved holder is equally adapted for vertical or slanting writing,and, furthermore, it enables one to readily determine the rightdistance from the end of the forefinger to the pen-point, usuallya fault with ordinary penholders, thus facilitating accuracy in the formation of letters.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improved penholder, the interior parts being shown in dotted lines. Fig. 2 is a perspective view of the casing or body of the penholder. Fig. 3 is a detail perspective view of one extensionsection of the body. Fig. 4 is a perspective View of a plug adapted to slide in the extension shown'in Fig. 3. Fig. 5 is a side elevation of the plunger which is located in the bodycasing of the penholder and an improved pen located in theplunger. Fig. 6 is alongitudinal vertical section through the improved penholder complete and the pen in the holder. Fig. 7 is a transverse section on the line 7 70f Fig. 2, and Fig. 8 is a plan view, of a pen especially adapted for use in connection with my invention; and Fig. 9 is a longitudinal section through the outer end of the penholder and likewise a longitudinal section through the pen, the view being upon a large scale.

The body A of the holder is made of rubber, gutta-percha, or other suitable material and is in the form of a tube, the preponderance of material being at its upper portion, as shown in Fig. 7, and in the upper portion of the body A an interior longitudinal groove is made, (indicated at 10,) which extends usually from end to end. The extension-section B is provided for the body, being adapted to enter its upper end and closely fit within the body; but while the extension-section has end movement it is held against rotary movement bya pin 11, secured on or forming an integral portion of the extension-section, which pin enters the groove 10 in the body.

- A plug 0 is adapted for end movement in the extension-section B to and from an apertured partition 12 made in the said extensionsection. The plug 0, as shown in Fig. 4, is preferably provided with an enlargement 13 at its forward end, and when said enlargement is snugly fitted in the extension-section Bthe plug cannot be accidentally entirely withdrawn from said extension-section. The plug is provided with a pin 14-,-which enters a groove 15, made in the interior of the extension-section B, so that the plug 0 cannot turn in the interior of the extension-section.

A plunger 16 is adapted for end movement in the body A and in a portion of the extension B of the body. This plunger is preferably made quite Wide at its forward end and is provided with a slot adapted to receive the body portion of a pen, such as the pen 19. The upper end of the plunger 16 is loosely passed through the opening in the partition 12 of the extension B of the casing, and the plunger is prevented from leaving the extension of the casing by passing the pin 17 through the plunger at the rear of the partition, as illustrated in Fig. 6. I A spring 18 is attached to the upper end of the plunger and to the inner or upper end of the plug 0. When a pen is introduced into the forward end of the plunger and is employed in writing, the spring 18 will act as a cushion, preventing the pen from hearing too severely on the paper and also preventing the stiff action common to pens and penholders that causes a cramp in or a Weariness of the hand. By moving the plug 0 inward or outward, more or less tension maybe brought to bear on the plunger 16.

The plunger is prevented from turning in the body by forming on the plunger a pin 21., which enters the groove 10 in the body A of the casing, the pin being held in position in the said groove by means of a spring 22, located on the plunger at the surface below the pm.

By moving the extension-section B it is evident the plunger may be given end movement, causing the pen to extend a greater or a less distance below the lower end of the holder.

The spring 22 is secured to the plunger at its rear end by a screw 23 or its equivalent and the outer end of the spring is bent upward in front of the plunger, as shown at 24, an adjusting-screw 25 being passed through the upturned end of the spring and into the plunger in order that the spring may be made to bear with more or less force against the plunger and bind the pin -21 more or less tightly against the body or barrel A.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A penholder consisting of a casing, a plunger having guided end movement Within the casing, the plunger being provided with a seat for the pen, a cushion-spring attached to said plunger, a plug having end movement in the body of the holder and attached to the cushion-spring, a tension-spring located between the plunger and the body, and an adjusting device for the tension-spring, substantially as described.

2. In a penholder, the combination, witha tubular body having a longitudinal groove therein,an extension-tube for the body having a projection entering the groove in said body, the extension-tube being capable of end movement within the body, and aplug having end movement in the extension, being provided with a'projection adapted to enter a longitudinal groove in said extension, of a plunger having aseat for a pen, a projection entering the groove in the body, and a spring below the extension, having bearing against the inner surface of the body, an apertured partition in said extension, through which the plunger freely passes, and a spring connecting the plunger with the said plug, substantially as shown and described.

3. In a penholder, the combination of a tubular body portion with an interior groove, a tubular extension-section mounted to slide in the body portion and having a stud fitting in the groove thereof, a plug fitting in the end of the extension-section, the plug and extension-section havinglan interlocking groove and projection to prevent the turning of the plug, a plunger mounted in the body portion and adapted to carry the pen, the plunger having sliding connection with the extensionsection, and a spring connecting the extension-section and the plunger.

4. In a penholder, the combination of a tubular body portion having an interior groove therein, a plunger fitting in the body portion and adapted to carry apen and having a stud fitting in the groove of the body portion, a spring attached to the plunger adjacent to the stud and adapted to push the stud into the groove an extension-section fitting in the body portion, and a spring connec tion between the extension-section and the plunger.

5. In a penholder, the combination of a tubular body portion, a plunger fitting in the body portion, a tubular extension portion also fitting in the body portion and having connection with the plunger, a plug fitted in the extension-section, and a spring connecting the plug and the plunger.
