PROVISIONAL SPECIFICATION.
Process and Apparatus for Glazing Leather.
We HERMANN BOGENSCHILD, Locksmith, and FRIEDRICH BUSCH, Engineer, both
of Zimmerstrasse, Berlin in the German Empire, do hereby declare the nature of this
invention to be as follows:-
This invention has for object to improve the glazing or glossing of leather by
means of an apparatus in which the glazing cylinder is not only moved to and fro
but also has a pendulous or tilting motion communicated to it. A pendulum rod
in connection with the glazing cylinder is operated from a crank rod so that the
glazing cylinder receives a pendulous motion. The latter is mounted between wood
bearing blocks and held in its fixed position in a casing by a cramp pressing it
between said blocks. The glazing cylinder casing is fixed to a cross head which
pivots at each end in a bearing at the side of the pendulum rod. These bearings
may slide up and down. The cross head is in connection with the crank rod by
intermediate rods. The leather to be operated upon is laid upon a table underneath
the glazing cylinder and the crank rod set in motion, whereupon the pendulum rod
moves to and fro, communicating this motion to the glazing cylinder. Whilst the
crank rod is moving towards its lowest position its presses down the rods connecting
with the cross head so as to turn this latter round on its bearings and consequently
also the glazing cylinder pressing the leather between cylinder and table. On the
upward motion of the crank rod the pendulous or tilting motion of the glazing
cylinder takes place in the contrary direction.

COMPLETE SPECIFICATION.
Process and Apparatus for Glazing Leather.
We, HERMANN BOGENSCHILD, Locksmith and FRIEDRICH BUSCH, Engineer, both of
Zimmerstrasse, Berlin in the German Empire, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention has for object to improve the glazing or glossing of leather by
means of an apparatus in which the glazing cylinder not only moves to and fro but
also has a turning, pendulous, or tilting motion communicated to it, owing to which
the cylinder presses the leather with greater energy, at the same time sliding, with
the alteration in the direction of force, over the leather.
The apparatus of the invention is shewn in the accompanying drawing
Fig. 1 being a side view.
Fig. 2 a front view.
Fig. 3 a bottom view and
Fig. 4. a view shewing the glazing cylinder in the tilted position.
A is the glazing cylinder pressed between wood blocks B by clamp C. The glazing
cylinder casing is fixed by screws or bolts to a crosshead D having a pivot E at each
end. The crosshead is connected to a pendulum rod F operated by crank rod G.
Pivots E are carried in bearings H which are held each by a screw I in side frames K
in which they are mounted to be capable of sliding up and down. L is a rod fixed
by one end in crosshead D and at the other end jointed to rod M which in turn is
jointed to cramp N attachable to crank rod G.

page_text: To perform the glazing process the leather is laid upon table O and rod G worked
from a crank set in motion by a motor so as to communicate a pendulous movement
to rod F and with it to glazing cylinder A. Whilst the crank rod G is moving
towards its lowest position the rod L is pressed down through rod M thereby turning
crosshead D round on its bearings. When, on the other hand, the crank rod moves
towards its highest position, the rod L is raised and crosshead D turned in the
opposite direction. The turning movement of the crosshead is communicated to the
glazing cylinder which during a pendulous motion has simultaneously an oscillating
motion on pivots E. By reason of the peculiar motion of the glazing cylinder so
obtained the leather under treatment receives a particularly beautiful gloss or glaze.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :
1. The process of glazing leather by sliding to and fro over the same a glazing
cylinder which simultaneously therewith and at given intervals is tilted or turned so
that the glazing cylinder is simultaneously in sliding and turning contact with the
leather, substantially as described and shewn.
2. For the purpose of performing the process referred to, a glazing apparatus
consisting of a glazing cylinder suspended on pivots E so as to turn thereon and
connected through rods L, M with a crank rod substantially as described and
shewn.
