TQ all whom t may @www Be it known that HAROLD ASHLEY STEVENS, subject of the King of Great Britain, residing at No. 388 Clapham Road,L
London, S. W. 9, England, have invented new and useful Improvements in Reservoir Pens and the like, of which the following is a specification.
This invention relates to propelling reservoir pens and the like, and its object is to provide clutch means for preventing breakage of a fountain pen of the propelling type, when the rotary effort applied thereto is continued beyond what is necessary to bring the parts into their respective end positions.
For the above purpose, a reservoir pen of the propelling type is, according to the invention, provided at the endv piece with a rounded spring-pressed laterally acting plunger, which engages with longitudinal grooves of a sleeve which may be the cap of the pen itself, to provide an eventually yielding clutch to avoid the effects of overrotation.
A suitable spring-pressed plunger is a metal or other rigid ball partially protruded yby a spring from a recess or socket of a configuration such as to prevent complete ejection of the ball.
Examples of the application of the invention are shown on the accompanying drawing, in which Fig. 1 is a sectional elevation of the rear end of a propelling fountain pen, and
Fig. 2 is an elevation partly in section of its cap.
Fig. 3 is an elevation partly in section of a propelling fountain pen with its cap in position on the rear end thereof, showing a modification,
Fig. 4 is a transverse view partly in section of the pen of Fig. 3, and
Fig. 5 is a similar view with the parts in a different relative position.
a is the barrel of a fountain pen and b is the end piece thereof. c is the removable cap. d is a ball pressed outwards by a spring e located in the end piece b to protrude laterally into contact with the inner surface of the cap c when the latter is fitted over the end piece.
The propelling fountain pen, mentioned above, is the well known one wherein the nib .122?" .Srie No'. me
g. is retracted into; and protruded from the 'barrel by being'inunte'd in a cup having a stem displaced longitudinally by a transverse pin on the stem engaged in a helical slotway or slotways 7i in a rotary sleeve rotated by the end piece b of the pen.
With such a propelling pen, as shown in Fig. 1, the ball d protruded by the spring e from the rotary end piece b, by coacting with one or more longitudinal internal grooves y' in the cap c fitted asusual on the end piece b, acts as a-yielding feather or clutch permitting the cap c to rotate idly over the end piece b when rotated beyond the extent necessary for protruding or retracting the nib g. The ball d in such event snaps from groove to groove in the cap.
The ball d and spring c are mounted in a transverse bore lc. The bore 71: extends only part way through the end piece b and the ball d and spring e are retained (Fig. 1) by a metal sleeve ring m, fitted over the end piece b and having a hole of less diameter than the bore lo, through which hole the ball d can merely partially protrude. f
Figs. 3, 4, and 5 show how the longitudinal grooves for the clutch engagement of the ball d by the cap b, canl be provided on the inner periphery of a rotary sleeve ring n, permanently surrounding the end piece b and gripped frictionally by the cap c removably placed thereon in the usual manner. Fig. 4f shows the ball Z engaged in a driving groove j whereas Fig. 5 shows such ball d ymidway between two such grooves j, in snapping from one groove to another after the nib g has beenI fully protruded or retracted.
The sleeve ring n, being permanently on the kend piece b serves also to retain the 2. In a propelling reservoir pen and the like having an end piece, Aan internally longitudinally grooved separable cap, a ball in Said end piece and a spring inrsaid end piece pressing said ball laterally outwards into a position to engage a groove of said Cd Y g. In a propelling reservoir pen and the like having an end piece, an internally longitudinally grooved lsleeve Surrounding said end piece, a rounded plunger in said end piece and a spring in' Said end piece pressing said plunger laterally outwards in- In testiinon whereof I have Si ned In Y naine to this Specification.
