Letters Patent No. 93,426, dated August 10, 1869.

IMPROVEMENT IN 'coMPosINsTIcKs The Schedule referred to in these Letters Patent-and making part of the same.

To all whom it may concern.- v

Figurel is a plan of my improved composing-'s'tick;4

Figure 2 is a front elevation; and Figure 3 is atransverse section on line y y on figs.

The same letters refer to the same parts in all the figures.

The nature of 'my invention relates to the manner of attaching the movable jaw or gauge to the back and holding it at the desired point, and consists in the use of alongitudinal'groove formed in the inner face of the back of the stick of such a form as to hold the head of the'claniping-bolt, so as to clamp the movable jaw or gauge firmly to the back when the holding-nut is screwed up. .t y t t -My invention also consists in theuse, in combination with said groove, -of a clamping-bolt and thumbnut, so arranged and applied that no portion of the clamping-device shall project above the common level of the'top of the stick, said bolt being fitted to slide in the groove formed in vthe backoftle stick, the

whole stick being so'constructed'thatthe outer sury l face of back and bottom shall be perfectly smooth and level. v

My invention produces a composing-,stick that is' easily and readily adjusted, that will rest in a steady position 011 any flat surface, whether resting on its bottom or o n its edge, and at the same time there are no-projections about it that interferewith taking an impression of the matter set up while it remainsinthe-stick.

AIn the drawingst A is the bottom, B the back, and C the fixed end, which constitute the main body of the stick. D is the movable jaw or' gauge.l

E is a groove formed in the back B, said back being made' from two pieces of metal to facilitate the construction of said groove-and riveted together.

' F is the clamping-holt, and v G, the'tl1umb1n1t,by means of which the clamping-v bolt is made to bind the parts together. l

The operation of my improved stick is so obvious that it needs no description.

v What I claim as new, and desire t`o lsecure by Let- 1 ters Patent, is y 1. The formation of a longitudinal groove upon the inner face of -the back, fitted4 to receive the'headl of a clamping-bolt, in such a manner that the gauge may be `set at any desired pointv by slightly slacking the holding-nut, substantially as described.

`2. In combination with the .groove E, the use of the clamping-bolt F, and-the thumb-nut G, arranged and applied substantially asl described.

Executed at Boston, this Sthday of June, 1869.

JOHN M. EATON.`
