To all whom it concern:

. Be it known t at 1,.THOMAKS OHALMERS GRANT, a subject of Great Britain, and resident of New Glas ow, in the county of Pictou, Province of ova Scotia, Canada, have invented certain new and useful Improve- I'nents in Fountain-Pens, of whichthe folfountain-gens and to remedy certain objections inei ent to fountain-pens as atpresent constructed and used.

Fountain-pens as heretofore constructed have been equi ped with a cap to protect the pgn-point, an this cap when the pen is to put into use, is removed from the point of the pen and applied on the outer end of the holder. After the use of the pen the 0:1: is removed from the outer end of the hotter and carefully restored to position over the point of the pen. My invention dispenses entirel with this cap and provides a slidable tu ular casin encompassing a portion of the length of t e en-holder and equipped with means for loc ing or retaining 1t in such given position as may be desir-edon the holder, whereby only the pen oint and adjacent part of the holder may e exposed when it is desired to use the pen in writing and whereb also an increased portion of the pen-hol 'er may be exposed when it is desired to remove the socket end of the pen-holder for filling thefountain with ink. The casing is also provided with a self-closing lid at one end and also with a concealed spring for moving it to its initial 7 or protecting position when its locking device is released to permit the spring to act.

The nature of the invention and the means for carrying the same into efi'ect will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in

Figure 1 is a central vertical section, partly broken away, on the dotted line 1-1 of Fig; 2, of a pen-holder equipped with an exterior casing and cooperating parts embodying my invention, the casing being shown m the position it will occupy when it Specification of Letters Patent.

Application filed February 27, 1909. Serial No. 480,342.

. is desired to employ the pen for writing purposes; Fig. 2 is an elevation of the same, taken from the right hand side of Fig. 1 and showing the exterior casing in the position it occupies when it is used for protecting the en-point, said casing having moved upward y from the shown in Fi 1 an its hinged end piece .having close over the pen-point; Fig. 3 is a view corresponding with Fig. 2 but showmoved downwardly to its extreme outer posit on so as to expose the socket for the penpoint preparatory to the removal of the with ink, and Fig. 4 is a view of the pensocket removed from the holder.

In the drawings, 10 designates a fountainpen holder having a pen-socket 11 and pen 12, all of usual or any suitable construction with the exception of such changes in the exterior surfaces thereof as become desirablein carrying out my invention.

The exterior casing or protector for the pen is numbered 14 and is in the form of a tubular shell which is less in length than the length of the pen-holder and is slidable is uppermost when the pen is in use, the casing 14 is provided with a spring-dog 15 of any suitab e construction for engaging,- when it is-s'o desired, one or the other of the recesses' 16 formed in the barrel of the holder 10. The engagin end of the dog 15 passes through a hole '1 in the casin 14 and is spring-pressed against the holder 10, and

with said end of said dog, the latter will become engaged with the holder and lock the casing 14 in fixed position thereon. The opposite end of the casing 14 is cut off on an inclined line approximating the inclination "of the side edgesof the pen-point and to cover this end of the casing 14 so as to conceal at the proper time the pen-point, I provide the casing with a bin ed end-piece or cover 18 adapted to fit against the edges of the end of the casing and to close said end, as shown in Fig. 2. The cover 18 will preferably be used in connection with a spring the casing moves to its protecting position shown in Fig.- 2 and to place a tension on said cover when the casing is away from its protecting position, as shown in Figs. 1 and 3", whereby said cover is kept pressed lightly Patented Sept. '7, 1909.

ing the inclosing casing as having beensame for enabling the fountain to be filled hence when either recess 16 passes into line osition in whlch it is i thereon. At its outer end or that end which 19 for automatically closing the same when against the pen-holder and prevented from swinging loosely.

It is my intention that the casing 14 shall remain a permanent art of the pen-holder and also that it shal have a spring action tending to move it to its protecting position, shown in Fig. 2, and to this end I provide within the casing a coiled spring 20 which at one end bears against an interior annular shoulder 24 on the casing and at its other end against a shoulder 22 formed on the holder 10. I also provide the casing with a screw 21 whose inner end enters a longitudinal groove 23 formed in the holder 10, and said screw and groove cooperate to prevent the holder from turning within the casing or the casing turning on the holder and also to limit the endwise movement the casing may have on the holder. When the casing 14 is in its protecting position, shown in Fig. 2, the point of the screw 21 is at and becomes arrested by the end-wall of the upper end of the groove 23, and at this time the spring 20 will exert a sufficient tension against 'the shoulders 22, 24, to maintain the relation of the casing and holder with proper firmness. \Vhen the casing 14 is in the position shown in Fig. 2 the pen-point will be well protected by the casing and its cover 18 and the pen may be carried in the pocket as usual. When it is desired to use the pen, the penholder may be withdrawn from the pocket and have its outer end placed on a table or other support and thereupon, the user only employing his one hand for the entire operation, the casing 14 may be pressed downwardly along the holder 10 and against the stress of the spring 20 to the position in which said casin 1s illustrated in Fig. 1, upon reaching whlch position the casing will become locked by the engagement of the dog 15 with the inner recess 16. The pen will then be ready for use, and when it is desired to restore the pen-holder to the pocket again, the user will simply release the dog 15 so as to enable the spring 20 by its expansion to slide the casing and holder into the relation in which they are shown in Fig. 2, the casing passing beyond the point of the pen and the cover 18 automatically closing over said point.

During the ordinary employment of the pen, the casing 14 will be at its intermediate position, shown in Fig.- 1, with the pen-point exposed for writing purposes, said casing being locked in such position by the engage-i ment of the dog 15 During the period that the pen-holder is carried in the pocket or laid away, the casing 14 will be in its protecting position shown in Fig. 2. When it is desired to re-. more the pen-point socket and fill the holder with ink, the exterior casing 14 will he slid downwardly on the holder 10 until thedog 15 reaches and engages the outer recess 16 with the lnner recess 16.

or to the position shown in Fi by ressing on the exposed en l of the dog, ena lin it to pass by the inner recess 16. When t 1e casing is in its extreme position shown in Fig. 3, the socket 11 becomes exposed and may be removed and the holder filled with ink, and thereupon after the socket is restored to the holder, the owner of the pen may release the dog 15 and per mit the spring 20 to restore the casing 14 to its protecting position shown in Fig. 2 or only to its intermediate position shown in Fig. 1, leaving the pen-holder in condition for immediate use. ably be slightly convex on its inner face, and during the movement of the casing 14 in a direction from the pen-point the penpoint does not strike does the lid strike against the pen-point, when closing the outer end of the casing 14, the edges of the socket for the pen being utilized for forcing the lid 18 to its open position and for receiving the pressure of the lid 18 during its closing movement.

The casing 14 answers as an entire substitute for the customary caps used on fountain-pen holders and constitutes a permanent part of the holder. The casing 14 is merely slid on the pen-holder when moved to its several positions and it may be operated with entire ease by one hand.

What I claim as my invention and desire to secure by Letters Patent, is:

1. In combination, a fountain penholder, a casing slidably mounted thereon having a closing cap at one end for protecting the pen-point, a spring normally acting to move said casing to its initial protecting position, and means for locking said casing when slid on the handle to expose the pen-point; substantially as set forth.
