PROVISIONAL SPECIFICATION.
A Polishing and Surfacing Apparatus for Cylinders.
I, PHILLIPP ALFRED MOCK, of Arlen, near Constanz, in the Empire of
Germany, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is a polishing and surfacing apparatus to be applied,
in preparing and spinning machinery to pressing cylinders covered with cloth or
leather in order to compensate irregularities of surface produced by various
causes.
The improved device is in the main constructed as follows: On a rectangular
bearing frame are secured four adjusting bearings two on each of two opposite
parallel surfaces of the frame. These bearings serve to receive a polishing drum
and a friction drum which are arranged parallel to each other at a distance of from
5 to 8 millimetres, so that the cylinder to be polished can be placed between the
upper portions of the drums.
The polishing drum consists of a cylinder made preferably from sheet iron. On
clongations of its shaft can be secured respectively a rope or strap pulley and two
strap pulleys, one loose and the other stationary. The friction roller is made the
same as the polishing roller its shaft however carries only a rope or strap pulley on
the same side as the corresponding pulley of the polishing roller. The surface of
the latter is coated with a layer of fine adhesive glass substance and the friction
roller with a layer of an emery substance.
The pressing cylinder to be treated is placed on and between the two cylinders.
The polishing cylinder is rotated by suitable gear in the direction towards the
pressing roller.
This rotation is transmitted by means of the rope or strap pulley
connection to the friction roller whereby the two drum-circumferences move in one
nd the same direction. The polishing drum and the friction drum arc in diameter
f the approximate proportion of 4:3 and rotate at a circumferential velocity of
bout 5 and 4 respectively. Great speed of rotation is required. The size and
isposition of the cylinders may vary according to the sizes of pressing rollers to be
reated.

COMPLETE SPECIFICATION.
A Polishing and Surfacing Apparatus for Cylinders.
I, PHILLIPP ALFRED MOCK, of Arlen, near Constanz, in the Empire of
Germany, Manufacturer, 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 relates to a polishing and surfacing apparatus for cylinders which
has for its purpose,
1) To so polish and surface newly dressed (i.e. covered with cloth or leather)
pressing cylinders of iron or wood used in preparing and spinning machinery and
liable to become untrue by unevenness or defective dressing of the leather or cloth,
[Price 8d.]

page_text: impressions or grooves produced by the continually passing threads, that they
regain the appearance of new or newly dressed pressing cylinders and can be
employed as such.
Referring to the accompanying drawing,
Fig. 1 is a top view and
Fig. 2 a cross section of the improved apparatus.
On each of two opposite sides F F of a rectangular frame E are secured two
bearings and which serve to receive the polishing drum A and friction drum B.
Said drums are arranged parallel at a distance of 5 to 8 millimetres from each other
so as to leave a space between them at their upper portions for giving support to
the cylinder to be polished and surfaced.
The polishing drum A. consists of a cylinder preferably made from sheet iron
having a shaft a which is so clongated as to allow it to have secured on it at one
end a rope- or strap-pulley m and at the other end loose and fast pulleys R
and R'.
The friction drum B is made the same as drum A except that the fast and loose
pulleys on one side are omitted. The outer surface of drum A. is covered with a
fine adhesive glass powder g, while the friction drum B is provided with emery
covering f.
The pressing cylinder C to be polished and surfaced is either a shaft of cast or
wrought iron or of wood, on the circumference of which is firmly glued a covering
of leather or cloth.
The pressing cylinder, which as may be seen from Fig. 2, is laid between the
drums A and B is polished and surfaced as follows:
The polishing drum A is set in rotation through a strap, guided over pulley R,
in the direction indicated by an arrow. This rotation is imparted by means of the
rope pulley connection to the friction drum B, so that both drums revolve in one
and the same direction.
The diameters of drums A and B are in approximate proportion of 4:3 and their
circumferential rotary speeds are approximately in the ratio of 5:4.
Drum A will have about 800, and drum B about 1000 revolutions.
The drum A works the periphery of pressing cylinder C with its vitreous
coating setting this cylinder into rapid rotation and grinding it off in the
direction indicated by arrows, while the drum B acts in the same way with its
emery coating ƒ.
By the described arrangement and owing to the rapid rotations coming into
operation, the pressing cylinders covered with leather are made precisely round,
while used and defective cylinders of this kind are made into such with smoothly
polished circumferential surface.
The improved machine is adapted to polish and surface all sorts and sizes of
pressing cylinders occurring in spinning machinery.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
A polishing and surfacing apparatus for pressing cylinders covered with cloth or
leather in preparing and spinning machinery characterised by the application of a
polishing drum A coated with glass powder and a friction drum B coated with
emery powder, said drums having unequal diameters and being adapted to rapidly
rotate at a distance slightly smaller than the diameter of the cylinder to be
treated in one and the same direction but with unequal circumferential speed,

page_text: thereby uniformly rotating and polishing and surfacing the cylinder to be treated'
substantially as set forth.
