Letters Patent No. 108,451, dated October 18, 1870.

IMPROVEMENT IN COMPOSING-STICKS.

The Schedule referred to in these Letters Patent and making part of the same.

We, AUcsrUs F. CLoUDnax, ot Brooklyn, in the countypof Kings and State ot' New York, and GEORGE W'. COFFIN, of Charlestown, in the county of Middlesex and AState ot' Massachusetts, have invented an Improved Printers Oomposing-Stick, ot' which the following, taken in connection with the accompanying drawing, is a specification.

Nature mi Objects of lllc Invention;

Our invention relates tothe means employed to secure the movable jaw to the back ofthe stick; and

It consists, first, in the formation ot' a groove in the bottom, said groove being located in the angle formed by bending up the back, into which tits a tongue formed upon the lower side ot' the movable jaw; and it also consists in the use, in combination with the above tongue and groove, of a clasp, formed by riveting a piece of sheet metal to the top of the movable jaw, 'and bending it down outside ofthe back, and under the bottom of' the stick, so as to completely surround the back of the stick, and form an L-shaped slot, extending the whole length ot" movable ja\v,into which the back ofthe stick slides.

It consists, in the second place, in the use oi' a paul-lever to clamp the movable jaw, said pawl-lever being pivoted to the jaw in a horizontal position, and nearly parallel to the projecting ar'm of the jaw, so as to move in a plane parallel to the bottom of the stick, the toe or point of the short arm ofthe lever resting against the inner surface of the back of'the stick.

Description of the Drawing. .Figure l a plan ot' our improved composingstick;

Figure 2 is an end view;

Figure 3 is a longitudinal section on the-linexx, on fig. 2; and

Figure 4 is a transverse section on line c' 5, on f 1.

General Description.

A is the botton'i,and D the back ofthe stick, formed from one piece of sheet-steel, bent at right angles, and having the groove c formed in the angle so made.

C is thc tixed jaw ot'the stick, and

1) is the movable jaw, havinga tongue formed upon its lower side to fit the groove a, as shown.

E is a piece of-shect-steel riveted to the upper side, ofthe jaw l), and bent down outside of the back and' under the bottom of the stick, to hold `the parts together.

The ja\v-.D has a mortse, l1, cut through it, parallel to the bottom, in which is placed vthe pawl-lever F,

pivoted upon the pin c, and having the spring d secured to its outer arm, and resting against the projecting arm of the jaw D, said spring serving the purpose of forcing the toe of the pawl F against the back of the stick, in a peitectly obvious manner.

rlhe short arm of the pawl-lever is so constructed that the point or toe ofthe pawl, where it touches the back ot' the stick, shall be at such an angle. to a line drawn through the center ot' its axis, and perpendicular to the back of' the stick, that when it is forced in v contact with the back, by the action of the spring (I, any attempt to Inove the jaw D in adirection to make the distance between it and the ti-xed jaw C greater, will cause the pawl to bite the harder, and resist all attempts to move the jaw D in that direction, without first releasing the pawl by pressing upon the long arm ofthe same, so as to compress the spring el.

The point ofthe pawl D is provided with teeth, to assist in securing a grip.

The groove a andthe tongue on the bottom of the jaw D, titting into the same, help to secure the jaw to the back, and prevent the strain of holding the jaw from bending the light clasp E, and thus enables us to use a much lighter clasp than we otherwise could.

1t is obvious'that the groove a, and the tongue to fit the same, may be used with other varieties oi' clasps and clamping devices than those shown, as, for instance, the clasp, instead ot embracing the whole back otl the stick, might be made to embrace a lip t'ormed upon the upper edge of the back "of the stick, and a set-screw might be used to clamp the jaw to the back in the usual manner, in combination with the clasp and the groove a, shown and described.

We do not, therefore, wish to confine ourselves to the particular combination and arrangement of the parts shown.

Having thus fully described our improved stick,

lVh-at we claim as our invention, and desire to secure by Letters Patent of the United States, is-

1. The pawl-lcver F, constructed, arranged and operating substantially as described, for the purpose specified.

2. The clasp E, the movable jaw D, andthe groove a., all constructed and arranged as set forth, in combination with any suitable clamping device, substantially as described.

Executed at Boston this 26th day of April, 1870.
