Abstract
Abstract A stand for holding and sealingly retaining a plurality of India ink drawing implements includes a like plurality of sleeves for holding the drawing implements and for sealingly retaining the implements to prevent India ink therein from drying. Each implement comprises a tubular drawing point, a grip having a front end to which the point is attached and an annular bid of the grip rearwardly of the front end. A tubular packing in each sleeve surrounds the drawing point and has an annular sealing lip at an end thereof remote from the drawing point. A packing insert in the interior of the packing has a plane face adjacent the drawing point. A tubular clamping element in each sleeve surrounds the grip adjacent the packing and has an inwardly projecting cam. A first spring biases the packing insert to press the plane face thereof against the drawing point and a second spring biases the annular sealing lip into contact with the front end of the grip while engaging the annular bead of the grip with the cam whereby the drawing implement is doubly sealed and retained.

A stand for holding and sealingly retaining a plurality of India ink drawing implements each comprising a tubular drawing point, a grip having a front end to which the tubular drawing point is attached and an annular bead of the grip rearwardly of the front end, the stand including a like plurality of sleeves for holding the drawing implements and for sealingly retaining the implements to prevent India ink therein from drying, a tubular packing in each sleeve and surrounding the drawing point, the tubular packing having an annular sealing lip at an end thereof remote from the drawing point, a packing insert in the interior of the tubular packing has a plane face adjacent the drawing point, a tubular clamping element inserted in each sleeve and surrounding the grip, the clamping element being adjacent the packing and having inwardly projecting camming means, a first spring means biasing the packing insert to press the plane face thereof against the drawing point, and a second spring means biasing the annular sealing lip of the tubular packing into contact with the front end of the grip while engaging the annular bead of the grip with the camming means whereby the drawing implement is doubly sealed and retained.
Claim 3
Dependent Claim
23 words
The stand of claim 1, wherein the first spring means has a bias of smaller force than that of the second spring means.
Claim 4
Dependent Claim
50 words
The stand of claim 2, wherein the annular bead of the grip and the camming means of the clamping element cooperate so that the combined biasing forces of the first and second spring means against the packing insert and the packing, respectively, securely seal the drawing point within the packing.
Claim 5
Dependent Claim
36 words
The stand of claim 1, further comprising an inwardly projecting bead on the packing, the inwardly projecting bead limiting movement of the packing insert towards the drawing point under the bias of the first spring means.
Claim 6
Dependent Claim
42 words
The stand of claim 1, wherein the tubular packing and the tubular clamping element have plane ends facing each other, contact between the plane ends limiting movement of the packing towards the clamping element under the bias of the second spring means.
Claim 7
Dependent Claim
19 words
The stand of claim 1, wherein the tubular packing and the packing insert are of elastic and vapor-impermeable material.
Claim 8
Dependent Claim
15 words
The stand of claim 1, wherein the clamping element defines a plurality of venting grooves.
Claim 9
Dependent Claim
27 words
The stand of claim 1, wherein the tubular clamping element is peripherally slotted to permit the camming means to engage the annular bead of the grip resiliently.
