It consists in connecting together, as hereinafter described, several lengths or divisions of a rule of any desired length. Two of these lengths are connected by a set-screw, which allows the connections to be placed and set at any desired angle.

IMPROVEMENT IN JOINTED RULES.
Specication forming part of Letters Patent No. 131,407, dated September 17, 1872.
To all whom it may concern:
Be it known that I, EDWARD PAECKERT, of Stratford, Ontario, Canada West, have invented certain Improvements in Rules, of which the following is a specication:
The object of Vmy invention is in constructing a rule, of two or more feet in length, that will answer the function or perform the service of any-shaped triangle, and also of an instrument to 1ind the desired angle of any object. It consists in connecting together, as hereinafter described, several lengths or divisions of a rule of any desired length. Two of these lengths are connected by a set-screw, which allows the connections to be placed and set at any desired angle.
In order to describe my invention more fully, I will refer to the accompanying drawing.
Figure I is a view of a part of my rule length- Fig. II is a View showing the rule set in the shape of an acute angle. Fig. III
is a view showing the rule folded and set in the shape of a triangle.
A, B, and C represent three dividedoff lengths orparts of a rule or measure fastened together by rivets a. To give strength and rmness to the different parts I have out at or near the outer end of the length B a semicircular groove, b. Into this groove works a pin, o, fastened to the length G. As the lengths are laid out in a straight line the pin o strikes against the groove b at the point d, thereby preventing the lengths or parts from getting out of a straight line, whichwould otherwise be the case.` The lengths or parts A and B are held together by a set-screw, D. This is done for the purpose of obtaining any desired angle, and for holding it rmly in the desired angle, as in Fig. II. This obviates the necessity of having an independent tool for such purpose, as is generally the case. To the end of the piece C, I may attach an additional length, E, to allow the angle to be changed or the base of lthe-triangle to be elongated.
Having thus fully described my invention, I desire to claim- The within-described rule composed of the sections A B G, curved slots b, and pins c, and set-screw D, all constructed as and for the purposes set forth.
