. y G. G. FELT CAP ATTACHMENT FOR FOUNTAINPENS Patented Jan. 25, 1927.

UNITED STATES GEORGE G. FELT, E wAsrrINGToN, DISTRICT' or' conclusie.

CAP ATTACHMENT FOR FOUNTAIN PENS.

Application led December 8; 1925.

The present invention relates to a cap attachment for fountain pens and the like, and aims to provide a novel and improved device of this character whereby the cap will be at all times carried by the pen and may be conveniently moved and placed on either end of the pen, according to whether or not it. is desired-to use the pen, thus eliminating the danger of losing the cap as often occurs with pens now on the market.

Another object of the invention is to provide a device as above outlined comprising a pair of bars arranged on opposite sides of and pivotally connected to the pen and cap, said bars having their ends that are pivotally connected to the pen arranged for sliding longitudinally thereon and having yieldable means for normally returning or holding the endsl of the bars pivoted to the pen approximately midwayl ofthe length of the pen, so as to yieldably hold the cap on either end of the pen.

It is also an obj ect of the invention to provide a device ofthe above indicated character, which is simple and substantial in construction, which can be manufactured economically, which will'not interfere with the efficiency of the pen, and which will be thoroughly efficient and practical in use. l

With the foregoing and'other objects in view, which will be apparent as the description proceeds, the inventionresides in" the construction and arrangement of part-s, as hereinafter' described and claimed, it being understood that changes canbe made within the scope of what is claimed, without departing from the spirit of the invention.

The invent-ion is illustrated in the accompanying drawing, wherein:

Figure 1 is an elevation of my improved pen, showing the cap in various positions as indicated by dotted lines,

Figure 2 is a longitudinal section taken on line 2-2 of Figure 1,

Figure 3 is a cross section taken-on line 3-3 of Figure 2, and

Figure L is a cross sect-ion tak-en on line' @-4 of Figure 2.

Referring to the drawing by numerals, the numeral designates the barrel of the pen which carries a point 11 on one end and has positioned therein the usual ink retaining bag 12. The cap 13 for the aen has the usual spring clip 14 carried there y for yieldably holding the pen in the pocket ofits owner when not in use.

serial No. 74,068.

In carrying out my invention, the numeral 15 indicates aipair of longitudinal slots arranged in the barrel '10 and on opposite sides thereof, said slots extending practically the entire length of the barrel 10 of the. pen. Positioned in the barrel 10 and secured at the slots 15 are cylinder members 16, which are provided with reduced ii.eckportioiis 17 along the longitudinal sides thereof, said neck portions having the edges thereof turned over, as at 18, for securing the cylinder members 16 within the barrel 10. From the foregoing, it will be noted that the cylinder members 16 are provided with a' reduced opening extending to the exterior of the barrel 10.

Arranged in each of the cylinders 16 .is a

head/or piston 19, provided'with a reduced extension 2O which extends, through theyreduced neck portion of the cylinders.y Connected to each ofthe headsor pistons 19 is one end of apair of bars 20, saidbars having their ends which are connected to the heads or pistons 19 turned or bent at right angles, as at 21, and extending through openings 22 provide-d through the heads or pistons 19 and their reducediextensions 20. The ends of the angled portions 21'ha-ve heads 22 arranged' thereon for preventing disengagement of the bars 20 from the heads ory pistons 19.

Arranged inthe cylinders 16 and upon both sides of both pistons ,or heads 19 are small coil springs 23, which abut against the heads or pistonsA 19v at one end and -have their opposite ends abutting against end Y closing walls 24C provided upon the ends of the cyl-v inders. From the foregoing it canA be seen that the coil springs will normally hold the heads or pistons in positions approximately midway of the length ofA the cylinders against tension of the springs 23.

Theopposite ends of the bars20 are also turned at rightangles, as at'25, and extend through a metallic band 26 arranged upon the cap 13, said right angled bent portions 25 also having heads 27 thereon for preventing dis-engagement of the bars 20 from the ring 26 and cap 13. It will be noted. that the bars 20 each have one end therof pivotally connected to the barrel of the pen while the opposite ends thereof are ypivotally connected to the cap 13, so asto permit relative swinging movement of the cap with relation to the barrel of the'l pen.

In operation, the-cap 13 may be positioned CII upon either end of the barrel l0 of the pen. and by sliding the cap 13 away from the barrel l0 until the same is beyond the end of the barrel or the point 1l of the pen and then swinging the cap to a position such as indicated by dotted lines in Figure l, the cap may be swung around and moved to the opposite end of the barrel by exerting a pull on the cap against tension of certain ot the coil springs 23. As soon as th-e cap is properly positioned at either end of the barrel l() and released, the coil springs 23 Will move the cap upon the barrel and hold said cap in such position. From the foregoing, it can be seen that the cap is at all times carried by the barrel ot the pen, thus eliminating the 'danger ot losing the cap While changing the same from either end of the barrel.

Having thus described my invention, what claim as new is:

l. A device of the character described in combination with a pen and cap, comprising means slidably mounted on the pen and connected to the cap for permitting the cap to be placed on either end of the pen.

2. A device ot the character described in combination with a pen and cap, comprising` a pair ot bars each having one end thereof pivotally connected to the barrel ot the pen and the other end pivotally connected to the cap, and means t'or slidably supporting said pivotal connection ot said bars on said pen so that said cap may be positioned upon either end ot said pen.
