Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1883 edition. Excerpt: ...low down on one side, while on the upper side is a tube, open at both ends and projecting into the can; this tube contains a piston which, when pushed downward, throws the Buhach out of the distributing tube in a fine shower, while a spring again pushes the piston upward in its proper place as soon as the pressure from above has been removed.

It was formerly constructed with an opening in the piston leading into the interior of the insufflator, through which the latter was tilled with the Buhach, the opening being afterwards closed with a tight-fitting cork; but an improvement has lately been made by having nearly the whole bottom in the form of a screw-cap, like that on glass fruitjars, which can be removed by being unscrewed; by this arrangement the insufflator can be filled much easier and quicker than by the old way. The present price of this insufflator is 25 cents each. The second instrument, referred to above, is intended for distributing the dry Buhach in large quantities. It consists of a tin can somewhat resembling a common lard-can holding 5 pounds of lard. In the lower part of the can, upon one side, is an opening, into which the nozzle of a small hand-bellows is inserted, while on the opposite side, also near the bottom of the can, is a smaller opening, leading into a spoon-shaped nozzle on the outside. This nozzle is furnished with a slide, so arranged as to regulate the quantity of the buhach that is forced through it by the bellows. The top of the can has an opeuiug 4 inches in diameter, and is closed by a tightly-fitting screw-cap, similar...show more
