is made without inconven'ence to the patient, 
nor is he in this, or any of the other changes, 
once touched or exposed to sight of cold. 
The bedstead is also convertible into an 
easy chair, and can be restored to its hori- 
zontal without disturbing the patient or de- 
ranging the bed clothes ; the bed-rest and 
pan are brought into use upon a new and 
most easy pi'inciple ; the latter is closed by 
an air-tight, self-acting valve, and all its 
operations are conducted without the least 
noise or jarring from the machinery, which 
is entirely concealed when the bed is made 
up. 
The revolving cylinder bedstead is an 
elegant structure, in the newest French style, 
with scroll back and canopy top, that it is 
not only applicable to cases of sickness, but 
available for ordinary use, imparting, from 
its peculiar construction, much greater com- 
fort, with a mere mattress, than is derived 
from a bed of the softest down when laid

jn short, it fully justifies the patronage of 
the most eminent of the faculty, possessing 
every conceivable convenience, unimpaired 
by a single objection.* — Ibid. 
HEBERT’S PATENT FLOUR-MAKING 
MACHINE. 
' From 0 personal inspection of the machine 
'delineated in pe'spec'.ive on the preceding 
■page, and from a caiefol perusal oi theinven- 
boiL specification, it appears to us to be his 
desian to construct flour-mills of tlie utmost 
-simplicity and duiabillity ; in which, not only 
the ^ri, tiling of tl>e corn, but the dres»i)i!r (sift- 
ing) of tlie meal into flour, pollard, bran, 
&c., are simultaneously performed. It is not, 
however, to be understood that these com- 
bined operations are effected by the nieie 
nnae.ratton of a dressing-machine to a mill, and 
driving them both together ; for in such an ar- 
rangement there would be neither novelty nor 
economy. But the combined operations of 
grinding and dressing aie in this new patent 
mechanism so simplified, and so intimate, that 
they are continuously going on, upon oneconti- 
tiiioiis snrfiice. The essential members of the 
machine are thereby reduced to onlytuari 
• one stationary, the other rotative. This re. 
tnarkable simplicity conduces to many advan- 
tages. which our mechanical rearlers will at 
tdnce appreciate, without our entering upon 
“ tlie details. The inventor has shown in his 
specificatian. and has actually put into beue- 
"flcial practice, several modifications of the 
principle so as to adapt the scale of their ope- 
rations to any required magnitude. We have 
selected for the present ai tide what the pa- 
tentee denominates his patent 'Jo/nest iV flour-

ofone man : but the power requisite to woik 
thi-i, may be diminished or incteast^'d at the 
pleasure of the operator, by a corresponding 
reduction or augmentation of the feed. oi quan- 
tity of coni permitted to pass under the opera- 
tion of the grindeis in a given time. In a sub- 
sequent Number we purpose inserting a de- 
scription of one of the same kind of machine.s, 
which is in use at the workhouse of Ail Saims 
near Heitford, where it i-s worked by any 
nuinlier of men, from two to ten (by a suitable 
alteration of the feed), and i-; capable of pro- 
perly grinding and dressing as much corn in 
a given time as other mills will giind only 
the estimated power required to vvork if effi- 
ciently, treing that of one horse. whetiier work- 
ed by that animal, or by wind, water, or

of the fly-wlieel ee. The axis a also carries a 
bevelled wheel, /, which drives a pinion jr 
fixed upon a vertical spindle h, that revolves 
in the centre of a metHllic hopper i, and car- 
ries at its lower extremity the upper grinder ; 
and to the perifihery of the latter is attaoiied 
a scries of brushes, that revolve together wdth 
it inside the circular case j, cast in one piece 
with the hopper t. The lower grinder is fixed 
in the centie of the flat top k of the pedestal ; 
and around the lower grinder, in the same 
plane as its superior surface, is an annulus of 
fine wire-gauze ; over the area of whicli the 
brushes sweep in their revolution, continually 
scattering every particle of the meal, as the 
same is constantly projected in minute quan.

ers, on to the wire-work ; causing the flour to 
fall through the meshes into the drawer mnt 
below: wliile the bran and pollard, which 
cannot pass the wire-gauze, are continually be- 
ing freed from their adiiering flour by the ac- 
tion of the brushes, until they are diiven 
through an aperture, at llie outer circum- 
ference of the wire-gauze, on to an inclined 
screen of coarse wire-work, where the offal 
separates itself, in tlie mere act of falling, into 
pollard and bran ; both of which deposit 
themselves into separate compartments made 
in the drawer n. All is a screw for regulating 
the admission of the corn ; and at o is a lever, 
over an engiaved plate, which directs th'o 
operator which way to move it, according 
as he may desire to regulate the grinding, 
whether coarser or finer than it was previous- 
ly set. I'ltese adjustments are obvious to the 
sight, and unerring in their action. 
Amongst the advantajges which this ma- 
chine presents to the economist, may be stated 
its convenience, portability, and perfect clean^ 
liness, and there being no dust or waste of
