ATTACHMENT FOR PENS.
SPECIFICATION forming part of Letters Patent No. 671,371, dated April 2, 1901 Application filed fieptember 6, 1900. Serial No. 29,219. (No model.)
To all whom it may concern.-
Be it known that I, ARTHUR BENJAMIN CRUIOKSHANK, mine proprietor, a subject of the Queen of Great Britain and Ireland, residing at 62 Chancery Lane, London, England, have invented a new and useful Attachment for Pens, of which the following is a specification.
This invention relates to an attachment for pens, the purpose of which is to permit an ordinary pen to take up and retain a larger amount of ink at a single dip than it would otherwise do, and consequently enable it to write a greater number of words for each dip.
The said attachment consists of a bulb or pear-shaped sheath or sleeve, of elastic material, in the body of which are holes.to admit the ink. At its broad end is a neck or opening to enable it to be slipped onto the pen, while at its narrow or pointed end it is slit up longitudinally, thus forming two lips, the extreme end of the lower one being cut away in order to prevent it touching the paper while writing. These lips check the toosudden flow of ink to the end of the pen-nib, and thus prevent blotting of the paper. The slitting is preferably continued far enough to leave two slits, one on each side, between the lips beyond the point where the extreme end of the lower lip is cut away. These slits allow a slight play of the lips while writing, thus facilitating the flow of the ink. They also allow the edges of the nib to pass between them. The space inside the sheath or sleeve forms a reservoir in which the supply of ink admitted through the holes is retained by capillary attraction.
Referring to the drawings, Figures 1 and 2 are respectively a side elevation and an under side view, considerably enlarged, of one form of the improved attachment. Fig. 3 is a plan, to a somewhat smaller scale, showing the attachment applied to a pen. Fig. 4 is a longitudinal section on line 00 w of Fig. 3.
a is the body of the attachment, which is hollow and constitutes the sheath or sleeve. It is circular in transverse section.
b is the neck or opening through which the pen is passed when the attachment is to be fitted onto it and which serves to grip the pen and hold the attachment in position.
0 and d are respectively the upper and lower lips,formed at the taper end of the body a. The upper lip c is so formed that it lies along the upper side of the nib, while the lower lip is partially cut away, as above referred to.
e is the slit which is left on each side between the lips and the purpose of which has been already mentioned.
frepresents the holes for admitting ink. They are preferably situated on the wide part of the body a, but somewhat toward the neck I), as shown.
g is a pen, which may be of any ordinary kind, and h is its nib.
It will be seen by a glance at Figs. 3 and 4, especially the latter, that the body a forms a reservoir which extends all around the pen and holds the ink by capillary attraction on the upper side of the pen as well as on its lower side. The projecting upper lip 0 serves to conduct the ink toward the'end of the nib, while the lower lip also assists in this action. The cutting away of the said lower lip obviates any risk of blotting which would otherwise occur if such under lip were extended to the same degree as the upper one, since in that case it would be likely to come in contact with the paper when writing.
The improved attachment can be applied to any existing pen, and therefore enables persons who have become used to one particular kind of pen to continue to use the same.
Having now described my invention, what I claim, and desire to secure by Letters Patent, is-
1. In an attachment for pens, the combination of an elastic bulbous body forming a reservoir both above and below the pen, a neck on said body for gripping the pen, and a pair of lips one of which lies along the nib of the pen and the other of which is partially cut away, substantially as described.
2. In an attachment for pens, the combination of a hollow elastic bulbous body having holes and slits therein, a neck at the broad end of said body, and a pair of lips at the taper end of said body, the upper of which projec-ts and the lower of which is partially cut away, substantially as described.
In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
