A CORPORATION OF DELAWARE.
Application filed August 25, 1926. Serial No. 131,343.
This invention relates to improvements in pen: desk sets, and has particular'reference toimprovements in desk sets comprising one or more fountain pens.
One object of the invention is to improve such desk sets by providing a simple and very efficient means for sealing the pen after insertion in a. cap forming part of the set in order to'prevent the ink from drying out and possibly clogging the pen. As a result of the. improved construction, a pen which has been supplied with ink is always ready for instant writing and the fact that the cap must be left behind when the pen is unsealed and withdrawn from the cap is a safeguard against putting the pen in the pocket and carrying it away.
With the foregoing and other objects in View, the invention consists in a novel construction and combination of parts, the novel features being pointed out in claims appended hereto, and a preferred form of em bodiment of which is hereinafter described with reference to the drawings accompanying and forming a part of this specification.
Of said drawings,
Fig. 1 is a side elevation, partly in section, of one of the improved sets with a fountain pen holder in pen receiving position.
Fig. 2 is substantially the same as Fig. 1, except that the parts have been moved to the pen sealing position.
Fig. 3 is a top plan View, partly broken away, and shows details of the way in which the holders are connected to the base.
Figs. 4, 5 and 6 show separately some of the parts shown in assembled relation in Figs. 1 and 2.
The embodiment illustrated in the drawing comprises a suitable base 10 provided with one or more upwardly extending lugs 11. There may be as many of these lugs as desired, the number depending upon the number of pens to be accommodated.
Each lug 11 is formed to constitute a stop shoulder 12, a cam surface or .eccentric 13 and a portion 14 which is nearly concentric with a pivot 15. Supported on the pivot 15 on opposite sides of the lug 11 are ears 16 integral with a sleeve 17. The sleeve 17 is flared at its other end as shown at 18 and the interior of the sleeve is provided with a circumferentially extending internal shoulder 21. Slidably mounted in the sleeve 17 is a cap 22 having its closed end rounded as shown at 23, this rounded end riding upon the cam 13 previously mentioned.
Between the upper or open end 24. of the cap 22 and the internal" shoulder 21 in the sleeve 17 is a gasket or ring 25 which is preferably made of live rubber and which, as made, has an internal diameter substantially the same as the internal diameter of the upper end of the sleeve 17. Vvhen the parts are in the positions shown in Fig. 1 the rubber ring resiliently holds the sleeve and cap in the relative positions indicated with the rounded end of the cap in contact with the cam 13 and with a portion 26 of the sleeve 17 in contact with the stop shoulder 12 of the lug 11. In this position the apparatus is ready for the insertion of a fountain pen.
After the pen has been inserted, until arrested by the end 21 of the cap 22, the cap and its supporting sleeve 17 are rocked on the pivot 15, causing the cam 13 to effect a movement of the cap 22 outward in the sleeve, thereby compressing the rubber ring 25 between'the end of the cap and the shoulder 21 in the sleeve, and causing the ring to be forced or bulged inward as shown in Fig. 2 so as to engage and form an air seal around the barrel of the pen.
The ring 25 will contact with the barrel of the pen before the sealing movement of the parts is completed and the sliding movement of the cap, in cooperation with the frietion afforded by the ring, will maintain or cause engagement of the internal shoulder 24 in the cap with the end of the pen barrel around the pen and ink feeding mechanism, thereby forming a secondary seal within the cap.
As the parts are moved from the position shown in Fig. 1 to the position shown in Fig. 2, the end of the cap 22 is brought in engagement withv the portion 14 of the lug 11, which. as before stated, is nearly concentric with the pivot 15 so as to retain the parts in the moved position with the seals about the pen in effective condition. It is preferred to make the portion 14 of the lug acting through the cap 22, as the latter passes off of the cam, to assst in completing the final movement of the sleeve 17 to the posit'ionshown in Fig. 2 and yieldingly holding it in that position. It is clear, of course, that the n'iovemcnt just referred to of the cap 22 must be comparativelyslight, as any COIlSltlQltlblO-lllOVtlllOllli relative to its support 17 would involve allowing the rubber ring to return so far toward normal condition as to effect a loosening of the seal around the pen barrel.
While the invention has been shown and described in one form of embodiment suitable for fountain pen desk sets, it is obvious that the apparatus may be used to hold pens and writing implements of other types. It is also apparent that the construction is capable of various modifications and changes to adapt it to different uses and conditions, and it is not the desire to limit the invention in any way except by such limitations as may appear in the claims which follow.
What is claimed is- 1. In a device of the character described, the combination of a base, a ca into Which the pen carrying portion of a fountain pen may be inserted, devices supporting the cap for movement relative to the base, and means whereby movements of the cap on the base will seal and unseal the portion of the pen within the cap.
2. In a device of the character described, the combination of a base, a ca into which the pen carrying portion of a ountain pen may be loosely inserted, devices supporting the cap for movement relative to the base, and means for effecting and releasing an air seal around the barrel of the pen by movements of the cap relative to the base.
3. In a device of the character described, the combination of a base, a cap into which the pen bearing end of a fountain pen may be loosely inserted, a support for the cap pivoted to the base, and means whereby movements of said support on its pivot will effect and release an air seal around the barrel of the pen and adjacent the cap.
4. In a device of the character described, the combination of a base, a receptacle for the pen bearing end of a fountain pen comprising a stop to engage the lower end of the pen barrel, a support for the receptacle movable relative to the base, and means whereby movement of the support and receptacle in one direction will effect an air seal around the pen barrel adjacent the re ceptacle and release said seal when moved in the opposite direction.
In a device of the character described, the combination of a base, a cam on the base, a receptacle for the pen bearing portion of a fountain pen, said receptacle cooperating with the cam, a support for the receptacle pivoted to the base adjacent the cam, and a resilient element for maintaining contact of the cam and the receptacle in all positions of the support and operated to form an air seal of the portion of the pen within the receptacle when the support is moved to one of its positions.
6. In a device of the character described, the combination of a base, a cap into which the writing end of a fountain pen may be inserted, a support for the cap movably attached to the base, means for effecting a relative movement of the cap and support by movement of the support in one direc tion, and a resilient device cooperating with the cap and support and actuated by said relative movement to form an air seal around the barrel of a pen inserted in the cap, said device operating to release the seal and effect a relative movement of the cap and support when the support is returned to its original position.
7. In a device of the character described, the combination of a base provided with a cam, a tubular element provided with ears pivoted astride of the cam, an internal circumferentially extending shoulder in said element, a fountain pen cap slidably mounted in the tubular element and having its closed end riding on the aforesaid cam, a shoulder on the ca to be engaged by the pen-carrying end 0 the pen barrel, and a compressible and expansible ring seated between the open end of the pen cap and the shoulder in the tubular element.
