(Application filed Sept. 29, 1900.)

PENCIL-HOLDER ATTACHMENT FOR Dl VlDERS.
SPECIFICATION forming part of Letters Patent NO. 677,995, dated July 9, 1901. Application filed September 29, 1900. Serial No. 31,558- (No model.)
To all whom it may concern; Y
Be it known that I, CARL KLAUI, of the city and county of New Haven, in'thc State of Connecticut, have invented a newanduseful Improvement in Pencil-Holder Attachments for Dividers and Similar Tools, of which the following is a full, clear, and exact description when taken in connection with the accompanying drawings, which form a part thereof, and in which'- Figure 1 represents a pencil-holder attachment embodying my invention affixed to one leg of a pair of dividers; Fig. 2, a vertical central section of the holder when so affixed Fig. 3, an enlarged top view of the holder; Figs. 4 and 5, enlarged central horizontal sectional views of the holder with the brake shoe in its open and closed positions, respectively; and Figs. 6 and 7, detail views of the rotary pin and brake-shoe, respectively.
In all the figures similar letters of reference represent like parts.
- This invention relates to attachments for holding pencils on dividers and similar tools;
and it consists in an independent attachment which may be aifixed to the leg of a divider and locked thereon by mechanism which, together with the means for clasping the pencil in the attachment, is operatedbya single instrumentality, as more fully set forth and claimed hereinafter, together with other improvements and combinations of parts.
Referring to the drawings, the part designated by the letter A represents the divider,.
the invention.
Between the'sides b and near the upper edge of the holder is pivoted at c a brakingshoe 0, the lower and free end 0' of which may be formed substantially V-shaped, the apex of which extends in the opposite direction from the apex h of the holder B.
Through the sides I) and near the point where the sides begin to curve outward is in- A serted a rotary pin D, held from longitudinal movement by washers E and e. The washer E is sufficiently broad to bear with one edge on the outwardlycurved portion b of one of the sides bfor the purpose more fully set forth hereinafter. The pin D is formed at its middle with an eccentric groove or other cam-like device, whereby one side is of greater 'width from the central axis than the other side. As the apex c of the brake C bears against the middle of the pin D, owing to the eccentricity of the pin at that point, the brake C will be swung on its pivot toward the apex b of the holder B upon the rotation of the pin D from the position shown in Fig. 4 toward that shown in Fig. 5. To this end the pin D is provided with a thumb-plated at one extremity. The pin D is further provided with an annular flange or shoulder d of such eccentricity that when in the position shown in Figs. 3 and 4 it does not bear on that portion of the washer E which rests on the curved portion b of the side b of the holder, while in the position shown in Fig. 5 it not only bears on the said washer E, but forces the same toward the center of the holder. By this means on the rotation of the pin D the curved sides I) are squeezed toward each other to grasp the pencil or other article between them. Thesame rotation of the pin D swings the brake O on its pivot toward the apex b of the holder B to grasp the log a of the divider between the apex b of the holder and the brake C, so that a single partial rotation of the pin locks the holder to the dividers and forces the outer ends of the holder toward each other to grasp the pencil.
I would call attention to the fact that by the adjustable featureof my holder owing to the braking-shoe the attachment may be fitted atnvarious heights on the leg of the divider and may fit dividers having their legs either round or angular in cross-section.
Having now described my invention, (which may vary in its details without departingfrom the spirit thereof,) what I claim, and desire to secure by Letters Patent, is
1. The combination with dividers or similar tools,0f a separately-formed pencil-holder attachment consisting of a single piece of sheet metal bent back on itself to embrace a 2. In a pencil-holder attachment for divid-: ers and similar tools, the combination with a holder formed of a single piece of sheet metal bent back on itself; of a braking-shoe pivoted Within said holder; and a rotatable pin having an eccentric surface adapted to bear on said shoe to swing the same on its pivot;
upon the rotation of said pin, substantially v tion, and with its end adapted to grasp the as described.
3. In a pencil-holderattachmentfor dividers and similar tools, the combination with a holder formed of asingle piece of sheet metal bent back on itself, the outer ends of which i are adapted to grasp the pencil; of a brakingslioe pivoted within said holder; and mechanism for simultaneously swinging said braking-shoe on its pivot and compressing said free ends of said holder, substantiallyasdescribed.
4. In a pencil-holder attachmentfor dividers and similar tools, the combination with a holder formed ofa single piece of sheet metal bent back on itself, to embrace one leg of the divider Within said bent portion, and with its free ends adapted to grasp the pencil; of a rotatable pin extending transversely through said holder for compressing said free ends of said holder upon its rotation in either direction, substantially as described.
5. A pencil-holder attachment for dividers or similar tools, consisting of a single piece of sheet metal, bent back on itself to embrace one leg of the divider within its bent porpencil between them, and a pin having an eccentric portion within the holder for locking the said leg withinsaid holder upon its rotation in either direction, substantially as described In Witness whereof Ihave hereunto set my hand this 28th day of September, 1900,
