JOHN KRALUND, OF BROOKLYN, NEW YORK, ASSlGNOR TO JAMES Al EDEN, SR.
' Specification of Letters Patent.
Patented Dec. 25, 1906.
Application filed April 6, 1906. Serial No. 310.387.
To all whom it may concern.-
Be it known that 1, JOHN KRALUND, a-'citi zen' of the United States of America, residing at the borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Rule Attachments, of which the following is a specification, reference being had to the accompanying drawings, forming part of the same.
Figure 1 represents a rule to which my attachments have been applied. Fig. 2 is an enlarged view of a broken portion of a rule with one attachment thereon showing plainly some of the special features of the at 3 is a plan view of the blank plete attachment ready for use.
p Figs. 5, 6,7, 8 show the pencil-holding form.
. My invention relates to attachments for rules or similar devices whereby a scribingcompass of any length may be readily made e use with such rule or a similar rod of a simple and economical attachment small enough to be readily carried in the pocket; and it consists in making an attachment adapted to be readily adjusted to any rule and when adjusted to render the combination a complete'compass ready for immediate use.
The attachment consists of a fiat plate, preferably resilient, bent, as shown, into a three-sided form, the free ends f f being preferably curved or concaved from the outer face to constitute finger or thumb ieces held together by the intermediate part and preferably at a little less than a right angle to the said intermediate part. The metal isthin and, as stated, is preferably resilient, that it may of itself bind slightly upon the rule when attached thereto. The intermediate part b is preferably of a width (from piece f to piece f) about equal to the ordinary thickness of a rule, that the extension therefrom leading to the concaved portions of the thumb-pieces may closely embrace the rule, and the bending to a little less than a right angle is done to provide a slight spring-pressure for holding the attachment upon the rule. The necessary pressure can, however, be produced by the pressure of the thumb and finger upon pieces ff.
From the intermediate part b a pin or point p, centered therein and usually riveted thereto, extends outward in a direction opposite to the direction in which the parts f f are projected. It may be a plain steel point or it may be a socket-piece adapted to hold a lead for marking, as may be desired, or a socket or clip may be secured to piece f, as shown in Figs. 5 8.
The extensions f f are apertured, as shown at a a, .to permit the user to note on the rule the measurement of the distance from one point to another, and said apertures are preferably so cut that there shall be a rentrant point of metal i exactly in line with the point of the pin 1) of the device or the axial line ofa pencil placed in the socket, if one be used on plate I), the result being that said indicatorpoint '5, lies over the exact line of the rule, which will show the distance between the two points of the complete device.
In use the clips or attachments arepressed upon the rule, being held there, as related, by a slight spring-pressure. They are adjusted to the proper lines and distances, that adjustment being facilitated by the views of the pieces and by that action clamps the attach-' ments tightly to the rule, and he may then scribe an are or a circle of the desired and already determined radius with great facility. The change to a greater or smaller radius is equally simple, and, as is manifest, the device may be used with any ordinary rule or even a simple strip of wood, metal, or other material. It may be applied, used, and re moved in less time than it takes ordinarily to adjust large scribing devices heretofore known, and when removed it takes u very little space in a tool-chest or pocket, w e at the same time it is so inexpensive as to strongly recommend it to mechanics who need & ome article for such service.
What I claim, and desire to secure by Letters Patent, is-
1. In a rule attachment the combination of a plate having two yielding finger-pieces, one of which is provided with an aperture through which anything clasped between said pieces may be seen, and an intermediate piece joining said finger-pieces and a clippiece extending from said plate and adapted of a spring-metal plate, combined'to' form an to hold a pencil as described,.all substantially intermediate piece andtwo finger-pieces exas set forth.- tending therefrom inthe same general direc- 2. In a rule attachment the combination tion, an aperture in said finger-piece, an indiof a plate having two yieldinglfinger-pieces, eating-point extending into the finger-piece one of which is provided wit an aperture aperture, and a markersecured to said sprin through which anything clasped between metal plate and provided with a point whic said pieces may be seen and an indicatingregisters with-the indicating-point of thefinpoint projecting into said aperture in line l ger-piece aperture aforesaid, all substantially with the center of the marker-holding piece '1 as set forth. hereinafter named; an intermediate piece In testimony whereof I have signed my joining saidfinger-pieces and a holding device, 1 name to this specification, in the presence of 30 secured to the main plate and adapted to i two subscribing witnesses, this 17th day of JOHN KRALUND.
holda pointed projection with its point reg- March, 1906.
istering with the indicating-point projecting into the aperture aforesaid, all substantially as set forth.
