- and others, for a Machine for finishing, 
glazing, and glossing of Leather. 
FJ NDEPENDENTLY of the combinati- 
on of the several parts of the machine, 
as represented in the specification, the pe- 
 culiar principles and properties of the in- 
vention consist, first, in placing any con- 
_ venient number of glazing or graining cy- 
lindrical rollers, at the extreme diameter 
of a wheel, or circular platesto which 
(a they are connected, with the ability of ex- 
tending or contracting the distance of the 
extreme of eachi roller or glazer from the 
centre of the wheels or plates to which 
_ they are joined, by any suitable machi- 
nery capable of promoting an accurate 
— ailjustment of the rollers or glazers over 
the whole extent of their length; which 
_ properties insure the same correctness of 
adjustment to any number of rollers or 
_ glazers, by which they are rendered ca- 
pable of traversing in one and tlie same 
circle, bearing in all their parts upomany* 
_- curve of the same radius which they de-, 
scribe. “A body of rollers or glazers so. 
placed upon’ a revolving spindle, axle, or 
_ shaft, act as so many burnishers, glazers 
or grainers on any docile surface with. 
_ which they come incontact, The degree 
_ of gloss which their friction will necessa~, 
rily create depends entirely on the velo- 
' city, pressure, aud quality of the.mate- 
rial on which they may-act.—Secondly : 
Tn the construction of the table which’ 
; ives or supports the leather while the. 
ing rollers, &c. act ‘on it, it must be: 
efully observed that the extreme of the 
lazing rollers, while connected to the 
evolving shaft, describe a cirele suitabie, 
4 to the curve of the tabie. When the rol-. 
Jers or glazers are thus adjusted to the ta- 
__ ble, it is brought up t0 any required de~» 
gree: of contact with them, having the

leather to be glazed placed between them 
and the table; she leather being therein 
subject to any degree of discretionary 
pressure which the operator may de- 
termine on, , The table approaching the 
revolving shaft, not only enables the lea~ 
ther to be passed across, but dowr the ta- 
ble in any required direction, while the 
roller-shaft is moving at any rate of velo- 
city; the quantity of any skin of leather 
to be glazed ata revolution of the roller 
shaft will depend on the length of the 
glazing roller, the length of the skin lying 
on the table, and the specd with which: 
it is moved across. the table to feed the 
operation of the glazing rollers. «The 
approach of the table to, the roller-shaft 
secures also the whole surface of any 
skin of leather being perfectly glazed or 
grained, notwithstanding any inequality in 
its substance, as the table accommodates. ~ 
such inequalitics by advanging to, and re 
treating trom, the revolving shaft as often 
as the inequalities in the substance of the 
leather may eccur. Under all cireums 
stances of inequality in the thickness of 
‘the leather, it. is still, however, by the 
power of the table, at all times eapable of 
creating an uniformity of pressure, if re= 
guisite; which contributes Jargely to pro- 
duce an uniformity of gloss ever the 
whole surface of any skin of leather, note 
withstanding the inequalities of substance 
‘and the «impediments, of holes which 
many skins of leather possess.—Thirdly <

shall determine the exact degree of coun 
tact to which the table shall approach, the 
roller-shaft. The apparatus for secnring 
this object is denominated the ‘ Table- 
guide, or Stop.” By the application of 
this -apparatus the table is prevented 
from running, jn upon the. rollers,. when
