On the other hand, by reversing invention consists in the novel form, combina the direction of relative rotation of the fountain tion and arrangement of parts hereinafter more pen proper and barrel II, they may be relatively ‘ fully described, shown in the accompanying shifted in the opposite direction so that the pen drawing and claimed. point I0 is retracted to a position within the In the drawing, wherein like reference char barrel II, as shown in Figures 1 and 5, so that acters indicate corresponding parts throughout it is enclosed and protected against accidental the several views: damage. In order to close the outer end of the Figure l is an elevational View of a fountain barrel I I when the point II] is in the retracted pen constructed in accordance with the present position of Figures 1 ‘and 5, said outer end of invention, the fountain pen proper being in re the barrel II is provided with a spring-closed tracted position with respect to the barrel of closure disc I6 hinged, as at I1, to a band l1’ the pen point enclosing and protecting device, as secured on the barrel II and adapted to auto desired when the fountain pen is not in use. matically close when the pen point ‘I0 moves to Figure 2 is a view similar to Figure 1,'partly the retracted position with respect to the barrel broken away, with the parts relatively shifted II. This disc is preferably of concavo-convex so that the point of the fountain pen proper is form, thereby enabling the user to fit the end of projected outwardly of the outer end of the bar the index ?nger therein while utilizing the rel of the point-enclosing and protecting device. thumb nail of the same hand in opening the Figure 3 is a side elevational view of the device 60 disc I6 preparatory to projecting the pen point as shown in Figure 2.

It will be noted Figure 4 is a central longitudinal section taken that the threaded portion I4 disengages from the on line Iii-4 of Figure 2, and barrel I l and moves out of the latter to the posi Figure 5 is an enlarged fragmentary section tion shown in Figure 1 when the pen point is taken on line 5——5 of Figure 1. 65 in retracted position, as desired when the pen 2,405,958 3 4 is not in use. In order to limit the amount of relative longitudinal movement which may be ordinarily given to the fountain pen proper with respect to the barrel H, removable set screws I8 are threaded through the barrel H at a point between the threaded portions l3 and ll of the barrel of the fountain pen proper, said screws and minor changes in the details of construction illustrated and described are contemplated with in the spirit and scope of the invention as claimed. being adapted to engage the threaded portion What I claim as new is: A fountain pen comprising a fountain pen proper having a barrel and provided with a pen point at one end of said barrel, and an enclosing and protecting device for said pen point includ [3 when the pen point is retracted and to en gage the threaded portion l4 when the pen point 10 ing a second barrel ?tted over the outer portion of said pen barrel and having threaded engage is projected, thus providing the necessary limit ment with the latter, whereby the pen and the ing action.

An important feature of the pres; upon relative rotation of said pen and said sec ent invention is that the pen point enclosing and ond barrel, said threaded engagement embody ing spaced external threaded portions on the pen protecting device normally remains in assembled barrel having threaded engagement in the inner relation to the fountain pen proper and is not detachable therefrom so as to be readily mis 20 end portion of said second barrel, and set screws placed or lost. The construction is such that in the second barrel cooperating with said spaced it may be conveniently and easily actuated, and threaded portions to limit the relative longi the construction is also comparatively simple and tudinal movement between the pen proper and durable. It is believed that the construction and said second barrel. manner of use of the present invention will be 25 readily apparent from the foregoing description, JOSEPH J. KELLEY.
