“In inserting this casing in the window frame it is only necessary to bore auger-lioles corresponding with the swellings, and chip out between the holes. The swellings fit snugly in the anger-holes, and it is not necessary to cut away wood neatly between the two auger-holes, as the sides of the box are less in diameter than the diameter of the swellings. The boxes can, by reason this construction, be more easily and cheaply inserted in windpw frames, and will be held just as securely and snugly in place as if the sides were more neatly fitted to the wood. ”

“My improvement relates to the ease, 11, made with an external surface composed of segments of cylinders, 0, at opposite sides, so placed that they are adapted to enter mortises formed by holes bored in wood, such holes intersecting so that the interior of the opening made in the wood will be corrugations corresponding with the corrugations upon the surface of the case.”

When Cowell made his improvements in pulley-boxes it was customary to insert pulley-boxes in the frame by making an auger-hole at each end of the proposed recess, and cutting away the intermediate wood; and a patent
The defendant has appropriated the invention of the Cowell patent, and a decree is therefore ordered for an injunction and an accounting.
