Patented Feb. 3, 1931' PATENT oFFicE JULIUS L. SCHNELL, OF ARLINGTON, NEW JERSEY Application filed May 8, 1929. Serial No. 361,286. g

The invention relates to improvements in desk sets and has for its object to provide a means of exceedingly simple nature whereby the writing instrument or holderis easily removed from the funnel of the desk set and positively. prevented from binding or becoming stuck or frozen in the funnel.

Ordinarily desk sets of the type to which V the invention relates are provided with a hard rubber funneland aholder made ofa similar material. When not in use the holder is inserted into the funnel and is held there by friction. Very often the holder is inserted in the funnel somewhat harder than necessary.

Whenrit is desired to remove it again considerable force must be usedin withdrawing it. This entails many disadvantages.

The base of the desk set which is made of .a substantial heavy material is often lifted bodily when withdrawing the holder. This is very annoying as it may slam back and scratch the'desk and the-jerk that is given as the holder leaves the funnel will result in ink being spattered from the pen. In cases" where ink has congealed on the holder and the holder has been inserted into the funnel with undue effort the holder has actually been broken off in removing it from the funnel and it has been necessary to drill out the part remaining in the funnel.

7 It is also very bothersome when a person is using the desk set to be forced to hold the base and funnel with one hand and remove theholder with the other. The holders also are very often scratched and 'marredin their appearance due to the harsh friction set up between the hard materials of the funnel and holder.

Funnels have been provided with a' large mouth and spring clips below the mouth to maintain the holder in position. While this construction eliminates some of the difficulties it is also disadvantageous due to the fact that an excessive amount of air is supplied to elimination of these serious faults by provid- This will result in the ink drying or hardening around the point and the feed and the pen will not be ready for use ing a simple means adjacent the mouthof the holder for positively maintaining the holder in position in the funnel without setting up undue friction and permitting at all times of the easy withdrawal of the holder regardless of the fact that it may have been inserted with unnecessary vigor. v

Other objects and advantages will become apparent as this specification proceeds. Iteferring to the drawings forming a part th'e're of and in which a preferred embodiment of the invention is illustrated:

Fig. 1 is an elevational view of a desk set with the holder in position in the funnel. In this view part of the funnel is broken out and in section to better illustrate the invention;

Fig. 2 is a fragmentary longitudinal sectional View of the funnel on a larger scale with the holder withdrawn and the parts positioned accordingly; Fig. 3 is a cross sectional View taken on line 33 of Fig.2;', I i

Fig. i is a detail perspective View of the sliding friction sleeve which engages the holder when in position in the funnelyand Fig. 5 is a detail perspective view of the threaded flanged member which acts as a stop in one direction for the friction sleeve and also provides an ornamentation for the funnel of the desk set. Referring again to the drawings the reference numeral 6 designates the base of the desk set. I I

Swiveled or otherwise secured at 7 to said base is a funnel 8. When not in use the holder 9 is inserted into the funnel. The holder 9 as illustrated'is a combination pen and encil.

However, it is to be understood that the, older The mouth of the funnel is threaded for I the reception of a retaining ring 13. The retaining ring is externally threaded at 14- to engage the interior threads at the :mouth of the funnel and is provided with a flat sloping flange 15. This flange insures the proper positioning of the retaining ring and when plated acts as a handsome ornamentation for the funnel. i

The friction sleeve 12 fits snugly within the counterbore 10 and the length of the sleeve is preferably somewhat less than the I depth of the counterbore. When the holder 9 is inserted in the funnel it will be engaged by the upper end of the sleeve 12 and the 15 sleeve will be carried downunti'l stopped by the shoulder 11. This position is illustrated in Fig. 1.

In removing the holder the sleeve 12 will be moved in the opposite direction and will contact with the retaining ring'13 secured in the mouth of the holder. This contact will be suflicient to break the friction bond be tween the holder and the sleeve and thus permit of the easy withdrawal of the holder from the funnel. Fig. 2 shows the position of the sleeve as the holder is being withdrawn. The movement of the sleeve 12 is so slight that it will not be felt by a person when inserting the holder into the funnel or withdrawing it yet this slight upward movement and contact of the sleeve with the retaining ringis ample to make certain of the easy withdrawal of the holder even when it has been forced with undue vigor into the funnel.

ULLL/ sleeve the light friction thus established willalways maintain the holder in its proper position and as heretofore stated allow for. its easy withdrawal at any time.

'The friction. sleeve maybe rounded off slightly as indicated at 16 to allow easier insertion of the holder into the funnel. The sleeve also beprovided with a plurality of saw cuts or slots 17.' The diameters ofthe holders very often vary and the slots 1Z will compensate for these variations.

A small opening 18 is provided in the funnel. This opening permits of sufficient air entering. the funnel to prevent the ink from running from the pen point but does not al low enough air to enter to dry or harden the ink about the point and feed portions of the I From the foregoing description and an inns spection of the drawings it will be apparent a funnel secured to said base, a friction sleeve slidably mounted in said funnel adjacent the mouth thereof, said friction sleeve snugly fitting the interior of said funnel and being made of a compressible resilient material adapted to engage a holder when inserted into said funnel and permitting of the easy withdrawal of the holder from said funnel,- and a retaining ring secured in the mouth of said funnel toprevent said friction sleeve from being displaced in relation to said funnel. y

2. A desk set having in combination, a base, a funnel secured to said base, a friction sleeve made of a compressible resilient material, said funnel being counterbored and said friction sleeve being slidably mounted in said counterbore, the shoulder formed by said counterbore acting as a stop to limit movement in one direction when a holder is being inserted into the funnel, and a retaining ring secured in the mouth of said funnel, said retaining ring being adapted to limit movement in the opposite direction and act to break the friction bond bet-ween the holder and said friction sleeve when the holder is being withdrawn from said funnel.

A desk set having in combination, a base, a funnel secured to said base, a friction sleeve made of a compressible resilientrmaterial, said funnel being counterbored and: said friction sleeve snugly fitting said counterbore and slidably mounted therein, a plurality of cuts in said friction sleeve to compensate for slight variations in the diameters of holders, the shoulder formed by said couns. terbore acting as a stop to limit movement in one direction when a holder is being inserted into the. funnel, and a retaining ringseoured in the mouth of said funnel, said retaining ring being adapted to limit movement in the opposite direction and act to break the friction bond between the holder and said friction sleeve when the holder isbeing withdrawn from said funnel.

movement in the opposite direction and act to break the friction bond between the holder and said friction sleeve when the holder is being withdrawn from the funnel, the inside diameter of said retaining ring being more than the inside diameter of said friction ring so as to insure against the holder contacting with said retaining ring.

5. A funnel for a desk set having in combination, a friction sleeve made of a compressible resilient material slidably mounted in said funnel, a shoulder to limit the movement of said sleeve in one direction when a holder is being inserted into said funnel, and a retaining ring secured in the mouth of said funnel to limit movement in the opposite direction and act to break the friction bond between the friction sleeve and the holderwhen the holder is being withdrawn from the funnel.
