CQIR'EBINATION RULE, CQMPASSES, SQUARE, AND ANGLE.
Specification of Letters Patent.
Patented Jan. 156, 1917.
Application filed May 29? 1916. Serial No. 109,614.
To all whom it may concern:
Be it known that I, Euros A. Pannx'r, a citizen of the United States of America, residing at South Tacoma, in the county of Pierce and State of Washington, have invented certain new and useful Improvements in a Combination Rule, Compasses, Square, and rllnglc, of which the following is a specification, reference being had there in to the accompanying drawing.
This invention relates to a combination rule, compass, square and angle, and has for its object the production of a simple and eiiicient instrument which may be used especially for educational purposes in schools and the like, wherein the same instrument may be employed for a number of difieu cnt uses.
Another object of this invention is the production of a simple and efiicient construction whereby the ruler may be so operated as to be conveniently used for a compass or as a pair oi dividers for measuring distances and the like.
A still further object of this invention the production of a simple and eilicienr means for holding the two sections of the ruler in a closed position when not in use, while being used simply as a ruler or measuring instrument.
With these and other objects in view this invention consists of certain novel combinaaions, constructions, and arrangements of parts as will be hereinafter fully described and claimed.
in the accompanying drawing: Figure l is perspective view of the device shown in a closed position. Fig. 2 is a perspective iew of the ruler having the sections swung with respect to each other for use as a compass. Fig. 3 is an end view of the device in a closed. position. Fig. 4c is an end view of the primary section of the ruler showing the pencil or pen gripping jaw carried thereby. Fig. 5 is a detail perspective of the pencil or pen gripping jaw removed from the ruler.
By referring to the drawing it will be seen that 1 designates the primary section of the ruler which comprises an elongated body having a beveled face 2 upon one side thereof. The auxiliary section of the ruler 3 is pivotally secured to the primary portion 1 by means of a pivot bolt 4:- A wing nut is threaded upon the pivot bolt 4 and is adapted to hold the respective sections of the ruler in a set or adjusted position with respect to each other. The auxiliary section '3 of the ruler is also provided with a beveled face 6 which is adapted to form a continuation oi the :tace 2 of the primary section 1 while the ruler is in a closed position. 'lhe rear face oi? each section is rounded as indicated by the numeral '7 in Fig. so as to constitute an even surface to prevent injury or scoring of the desk upon which the ruler may be placed.
The primary section 1 of the ruler is provided with. a concave groove 8 upon the inner face thereof, which concave groove 8 extends at an angle diagonally across the outer end of the primary section 1 of the ruler. A metal jaw 9 is secured to the inner face oi the ruler and has an angularly extending flange 10 which is fixedly secured to the inner face of the ruler, and this jaw 9 is provided with an overhanging or curled lip 11 as illustrated clearly in Figs. 2 and 5 of the drawing, which overhanging lip 11 is adapted to firmly grip pencil or other suitable marking instrument 12 for the purpose of firmly holding the same in engagement with the primary section 1 of the ruler. The primary section 1 of the ruler is also provided with a longitudinally extending channel or groove 12 within which a pivot point 13 is adapted to be placed while not in use. This point 13, however, While the ruler is being used as a compass, is adapted to fit in the aperture or socket 1 1 termed in the outer end of the auxiliary section of the ruler. It will, therefore, be seen. that by placing the point 13 in the aperture let as illustrated in Fig. 2 that an ellicient compass has been produced for the purpose of drawing circles should it be so desired.
A stop pin 15 is secured to the inner face of the auxiliary portion 3 of the ruler, and this stop pin 15 is adapted to fit in a socket 16 formed upon the inner face of the primary section 1 of the ruler, and when the auxiliary section 3 is swung to aclosed p0- on upon the primary section 1, this pin 15 by fitting in the socket 16 Will prevent the two sections of the ruler from swinging apart when the thumb screw 5 is firmly clamped down upon the bolt 4.
The primary section 1 of the ruler is provided with a right angularly extending indicating line 17 formed upon one face thereof which is adapted to register with the face 6 of the auxiliary section 3 of the ruler when the blade or section 3 of the ruler is swung at right angles to the blade or section 1 of the ruler. A diagonally extending line which may extend at an angle of substantially 45 to the longitudinal axis of the primary section 1 of the ruler is also formed upon the inner face of the primary section 1 as illustrated by the reference numeral 18 in Fig. 2. This line 18 will constitute an cilicient indicating means to allow the proper adjustment of the blade or section 3 with respect to the blade or section 1 for permitting lines to be drawn at right angles to each other or at angles substantially 15. It, of course, should be understood that any other indicating lines may be formed upon the primary jaw or section 1 for the purpose of securing other desired angles.
Having thus described the invention what is claimed as new, is
1. As a new article of manufacture, a ruler comprising a primary section and an auxiliary section, means for locking one section in an adjusted position with respect to the other section, one of said sections provided with a pocket, means cooperating with said pocket for firmly holding a marking de- XlCO in engagement therewith, means carried by the other section to secure a pivot point thereto, one of said sections provided with a socket formed upon the inner face thereof, the other section being provided with a pin adapted to fit in said socket and firmly hold said sections in a closed position against accidental swinging movement.
2. As a new article of manufacture, a ,ruler comprising a primary and an auxiliary section, means for pivotally connecting said sections together, one face of each section provided with an inclined edge, said primary section provided with a longitudinally extending pocket, a metallic spring jaw secured to one of said sections and fitting in said pocket to constitute an efiicient grip for holding a marking device in engagement therewith, said other section having a socket registering with said spring jaw of said first mentioned section, said other section provided with a pocket to secure a pivot point therein, and means for holding said sections in a closed position against accidental swinging movement.
3. As a new article of manufacture, a ruler comprising a primary and an auxiliary section, means for pivotally connecting said sections together, one face of each section provided with an inclined edge, said primary section provided with a longitudinally extending pocnet, a metallic spring jaw secured to one of said sections and fitting in said pocket to constitute an elficient grip for holding a marking device in'engagement therewith, a socket formed in said other section registering with said spring jaw of said first mentioned section, said other section pro vided *ith a pocket to secure a pivot point therein, means for holding said sections in a closed position against accidental swinging movement, and one of said sections provided with indicating marks formed thereon for facilitating the adjustment of one section at an angle with respect to the other section.
In testimony whereof I hereunto affix my signature.
