llVlACI-INE FOR BREAKING DOUGH.

Specification of Letters Patent No. 3,102, dated May 26, 1843.

To all whom, t may concern Be it known that I, LUKE SHAW, of Bath` county of Lincoln, State of Maine, have invented a new and useful Machine for Breaking Dough Preparatory to Kneading the Same for Baking, of which the following is a full and exact description.

The nature of my invention, which I call the bakers friend, consists in applying a crank, moved by hand or other power, affixed to the axle of a cog wheel, which moves two other cog wheels, on the axle of each of which is ailixed a crank, connected by a connecting rod to the outer end of a brake, the other end of which brake plays up and down in a mortise, secured by a pin or pivot, at the center of a circular platform, containing the dough, and revolving on trucks, by means of a band passing around it and over a pulley or axle, moved by another band passing o-ver the same, and also over the first axle. I

The machine is constructed by electing an upright frame, marked A, A, supported by four posts, marked B, B, B, B, in the drawing, rnily connected together by cross pieces or girts, C, C1, C2, placed at suitable distances from each other to support the axles herein described. On the middle of the girts or cross pieces marked C1, placed little more than one third of the distance from the top toward the bottom of the posts, is to be aiiixed on gudgeons, marked a, the axle, marked b, of a cogwheel, D, as large as the frame will permit, to be moved by a crank, c, atlixed to the outer end of said axle. 0n the two cross pieces C2 place the axles of two other cog wheels, d, d, one on each side` of the first, of the size proper to have the cog wheels mesh in with those of the first axle. On the outerend of each of these two axles is to be affixed a crank, e, attached by a connecting rod, f, to the outer end of a brake, marked Z, the other or inner end of which plays vertically by a tenon secured in a mortise,rg, at the center of a circular dough platform, marked E, by a pin or pivot, so that the outer end of the brake may be alterare inserted into the` lower cross pieces,V

nearly level with the platform; the band passing iirst around rollers inserted into the upper and lower crosspieces, at equal distances on each side of the axle, and at a distance from each other nearly equal to the diameter of the platform, for the purpose of keeping the band in place' on the axle or pulley; this last axle being moved by a band passing around it and also around the first axle. On the other end of the axlesl of the two upper cog wheels should be atlixed fly wheels, F, F, to regulate the motion. Instead of the band, cogs ori-the platform and axle intended to move it, may be substituted.

Another inode of operation is that of having a fixed semicircular or quadrant plat-k That l claim as my invention, and desirev to secure by Letters Patent, is-

The arrangement of t-lietable or platform,

and breaker, in combination with the cranks y i and cog gearing arranged and operating in the manner herein described. y A
