Description:

This invention relates to improvements in the construction of retainers or clips for fountain pens and mechanical pencils, and has reference particularly to a resilient support for the clip, whereby the latter may be a rigid member and still perform its proper function of clamping itself to the material of a pocket or other carrying medium.

The clips ordinarily used in connection with pens and pencils are constructed of spring steel or other suitable material which allows itself to be sprung outwardly under pressure to slide over and clamp itself to a supporting pocket. After extended use the clip loses its resiliency at the bending point and breaks. With this in mind it is the principal object of my invention to provide a rigid clip removably mounted in a cap of a fountain pen or directly in the end of a mechanical pencil, which clip is resiliently urged into clamping position by means of a separate spring disposed within the cap or pencil and adapted to exert its pressure against the clip to hold it in clamping position.

Another object of the present invention is to provide a novel clip of the character described which may be readily replaced in case of breakage without requiring tools or rivets to make the replacement.

I accomplish the objects of my invention by means of an arrangement hereinafter described, set forth in the appended claims, and illustratively exemplified in the accompanying drawings, in which: Figure 1 is a side elevational view of the upper portion of a fountain pen cap or mechanical pencil showing the clip broken away to disclose the arrangement thereof in the cap.

Figure 2 is a longitudinal, partially sectional view taken on line 2-2 of Figure 1; Figure 3 is a transverse sectional view taken on line 3-3 of Figure 2.

Referring to the drawings, 10 denotes the usual fountain pen cap or top portion of a mechanical pencil and comprises a cylindrically shaped housing having a transverse partition 11 disposed in its bore adjacent its outer end, the partition being integral with the housing and having a longitudinally arranged internally threaded core 12, which is approximately one half the height of the chamber 13 beyond the partition II and smaller in its outer diameter than is that of the chamber 13 to provide an annular space 14. The upper or outer peripheral wall of the chamber 13 is provided with an open slot 15 to accommodate the clip 16. The clip 16 is an inverted L-shaped rigid strip of metal or other suitable material, the shorter arm thereof being an annular member 17 and the longer arm forming the clip depending along one side of the cap 10. The curved angular section 18 of the clip begins at the slot 15 and turns outwardly and downwardly as illustrated particularly in Figures 2 and 3. The clip 16 is virtually a lever which pivots on the edge above the slot 15 and the longer arm of this lever is urged against the exterior of the cap by means of a helical spring 19 seated in the annular space 14 of the chamber 13 and adapted to engage under the shorter annular arm 17 of the clip to exert an upward yielding pressure upon the arm 17.

The outer diameter of the arm 17 is of the approximate diameter of the chamber 13 and is held therein and the angular section 18 within the slot 15 by means of a tip 20 which is of the diameter of the cap 10 and which is provided with a conical central opening 21 to receive the conical head 22 of a screw plug 23 projecting into the chamber 13 and screwing into the threaded bore of the core 12.

To install the present clip 16, the spring 19 is placed in the annular space 14 and the annular portion 17 is arranged over the spring with the section 18 projecting through the slot 15. The threaded end of the screw plug 23 is projected through the conical opening 21 and then through the annular portion 17 and into the threaded core 12. As the plug 23 is screwed down the tip 20 will seat on the end of the cap to close the chamber 13 and the spring will be compressed under the annular portion 17 as the conical head 22 seats against the conical wall of the plug. It will be seen that operation to open the clip to place it in clamping position over the pocket will not cause the clip itself to spring at its angular portion 18, but will simply cause the shorter arm 17 to swing inwardly against the pressure of the spring 19, which will continue to exert its pressure to continue the clamping action.

Having described my invention what I claim and desire to secure by Letters Patent is: 1. A cap construction of the character described, comprising a cylindrical shell having an annular chamber, a clip projecting into said shell over said chamber, a compression spring in said chamber to engage the clip to cause it to clamp against said shell, and a tip to close over the shell to hold the clip therein against the pressure of the spring, the said clip being positioned intermediate of said spring and said tip in said chamber.

2. A cap construction of the character described comprising a cylindrical shell having a transverse partition with an upright thereaded core, a helical spring embracing the core and projecting above the latter, a rigid L-shaped clip having its shorter arm projecting into the shell over the core and being engaged by the upper end of the spring, a tip to close the shell over the shorter arm, and a threaded plug screwed into the core and against the tip to hold the same on the shell. 3. A cap construction, as claimed in claim 2, in which the shorter arm of the clip is annular in shape to embrace the plug, and the complementary engaging surfaces of the plug and tip are conical. 4. A cap construction, as claimed in claim 2, in which the upper end wall of the shell is provided with a slot through which the angular portion of the clip projects to allow the depending longer arm thereof to be yieldably urged against the exterior of the shell by upward pressure of the spring against the shorter arm of the clip.
