it is separated by the action of the

The materials 1 find, best for this .pur-

from the weight of the drag, and as the 
rake recedes by the eccenuric motion, 
draws away the fur cut off; the drag 
now presses on the fur, while a second 
stroke is made, and another portion of 
fur cut, while the rake is raised by its 
machinery, sufficiently high in its back- 
stroke to be clear of the fur, and fall 
the next stroke in contact with the 
drag as before, and is again ready to 
draw away the fur about to be cut. 
The patentee next explains all the 
drawings attached to the specification, 
and shews ‘the manner in which they 
act; aud he adds: “I declare, that the 
description of the apparatus, and their 
parts, is the result of careful and prac- 
tical experiment, and are what I prefer 
and adopt in practice ; but further I de- 
clare, to prevent the infringement of 
adopting my principles, or any parts 
thereot, under the disyuise of a change 
of materials, dimensions, or prepor- 
tions, I claim the privilege of using 
any or all of the metals, or their com- 
-binations ; of altering my materials, di- 
aneusions, or proportions, according. to 
ithe intended scale of operation. And 
further, I do not confine myself to any 
particular mode of connecting my sad 
improvements .with the engine, or of 
communicating motion to them, -but 
adopting.all or any of those modes with 
which mechanics are well acquainted ; 
and claiming as my exclusive right all

In describing, this invention, Mr. Bun- 
dy says, the frame, or stock is made of 
metal, in which are fitted a,pair of stect 
dies, in manner of those ,generally used 
for, making screws, held together by cy- 
linders; the dimensions may be various, 
as the quality of the work requires: 
the dies generally used, are about .two 
inches long and one inch square. In 
the prominent. parts, and that side of 
each the two dies which come jin cons 
tact when in use, are made correspond- 
ing grooves, which, when pressed toge- 
tlier, form holes, each to, be the diameter 
of the shaft intended to-baye the head 
fixed on; these holes may be made: ta- 
pering upward, or contracted .at that 
part close under the. head, where half
