Speeificatinoers Patent. Patented July 31, 1911 "K0 Application filed March 28, 1917. Serial No. 158,042.

To all whom it may concern Be it known that I, CLARENCE A. Bnonur'r, a citizen of the United States, residing at WVilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Writing Implements, of which the following is a specification.

This invention relates to fountain pens and particularly to the cap for covering the pen point which thoroughly protects said point from injury and dirt, and through which the pen may be thrust when it is de sired to use the pen for writing purposes, thus avoiding thenecessity and trouble of withdrawing the cap from over the pen point and placing the same on the opposite end of the pen and then reversing this operation after writing to cover and protect the point. v

With the above objects in view, the invention consists in the novel construction, combination, and arrangement of parts hereinafter described, pointed out in the appended claims, and illustrated in the accompanying drawing, in which Figure 1 is an elevation of a portion of a fountain pen provided with the improved cap.

Fig. 2 is a similar view of the fountain pen, the cap however, being shown incentral longitu inal section.

Fig. 3 is an end view of the cap, and. Fig. 4c is a sectional view of the outer end of the improved. cap with the pen thrust therethrough in position for use; 1 1 In the drawings 10 indicates a fountai pen, orpen of other. type, pencil or'like implement, and 11 a cap fitting snugly over the pointed end of the pen 0 the point 12. The cap 11, as shown, is ,provided near its lower open end on diametrically opposite sides with bow springs .13

that are convexed outwardly and seated in suitably, shaped grooves 14:, formed in the cap on the inner side thereof. These springs press against the sides of the pen 10.:and serve to hold the cap securely but removably on the end of the same. The outerend of the cap 11 is flanged inwardly as'at 15 for a short distance leaving a central nearly circular openin :16 in the end of the cap, the pen point 12 and a short length of pen 10 maybe thrust. The opening 16 is undercut, as at 17', and adapted to fit said opening; and its under-cut portion handle,

' locking the r protecting is a shutter 18 pivoted at 19 to the flange 15 and Qrming a tight closure when in position'for the end of the cap. At one side of the cap a short distance below its outer end is a button 20 from the inner side-of which there projects a short stem 21 that passes through a longitudinal slot and serves to guide the button when moved by the finger. The slot '22 is preferably made L-shaped, as shown in dotted lines in Fig. l, to permit the button to be turned laterally when moved downwardly its full distance for the purpose of locking the same in its depressed position. 0n the inner end of the stem 21 is an eye in which is fastened one end of a relatively stifi' coil spring 23, the opposite end of said spring being attached to the shutter 18 diametrically opp0- site the hinge 19, and being an expansion spring serves to hold the door closed when the button is in the normal position shown I in Figs. 1 and 2.

In use, the pen point 12 will be protected by the cap 11 placed over the end of the pen handle and held thereon by the spring .cap to prevent the entrance of dust and protect the pen point. When, however, it is desired to use the pen for writing purposes instead of slipping the cap from the pen the button 20 is drawn downwardly, pulling the spring 23 and the latter in turn 22 in the cap swings the shutter 18 open,'as clearly shown m Fig. 4. The button may now be turned into the angular portion, 24 ofthe slot 22 shutter open. Then, by slipping the-cap 11 down upon the pen handle 10, the point will be thrust through the mg the cap will be moved in the opposite direction, the stem 21 disengaged from the angular portion of the slot 22 and the button pushed to the outer end thereof, thereby closmg the shutter and returning the parts to normal position.

What I claim is:

LA cap for protecting the point of a writing implement having an opening in its outer end, a swinging closure for, said opening, sliding means on the outside of said cap extending inwardly through a hook shaped slot therein for closing and opening the closure and locking the same in open opening 16 in position for use. After writ-- position, and a spring connection between said closure and the sliding means.

' sliding button on the side of the cap, and a connection between the button and the closure. p

3. A cap for protectingthe point of a writing implement comprising a tubular member adapted to slip over the point of said implement and having an opening in its outer end, a closure for said opening hinged to said end and adapted to swing inwardly, a button slidable longitudinally on one side of said cap, and a resilient connection between the button and the closure.

4:. A cap for protecting the ends of a writing implement comprising a tubular member adapted to slip over the pointed end of said implement and having an opening through its outer end, an inwardly swinging shutter pivoted to said end for closing said opening, a button slidable longitudinally on the side of said cap, a stem projecting in wardly from said button through a longitudinal slot in the cap, and a spring connection between said pin and the shutter.

In testimony whereof I aflix my signature in presence of two witnesses.
