COMPLETE SPECIFICATION.
Improvements in Machines for Cleaning Knives, Forks, Spoons,.
and other like Artioles.
1, WILLIAM WATSON, of Station Road, Wincobank, Sheffield, in the County
of York, Engineer, 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 :-
The invention in machines for purpose aforesaid comprises an improved con--
struction, combination, and arrangement of appliances, together with an improved.
automatic application and adjustment of pressure to the nip rollors of said.
machines.
Such being the nature and object of the said invention, the following is a.
complete description of same, reference being had to the accompanying drawings, in
which:-
Fig. 1 is a front elevation (partly in section), clearly illustrating the improved
machine.
Fig. 2 is an end elevation (partly in section) of Fig. 1.
At 1 is the framing, the standards 2 of which carry the bearings of the axles of
the rollers 3. 3 driven by toothed wheels 4. 4 and an intermediate wheel 5 carried
on a stud in the framing as ordinary; on the axis of the upper roller 3 is a wheel 6:
gearing with an intermediate wheel 7 which drives a similar wheel 8; wheel 7 is
carried on a stud in the boss 7, and the wheel 8 is carried on a through axis 9.
supported in the elongated boss 10, and having at one end a burnisher 11, and at
its other end a brush 12 and cylindroconoidal shaped burnisher 13, there being
polishing powder boxes or containers at 14 and 15, and 16 is a wheel guard.
At 17. 17 are spiral springs contained in casings 18. 18 and applied as shown,.
EO as to exert a direct upward thrust to the necks or axis blocks 19. 19, the latter
being free to move upwards in the open way of the standards 2. 2 of the end
frames.
The springs 17. 17 applied and operating as described, ensure at all times
uniform pressure or nip between the rollers, and the springs cannot be interfered
or tampered with, consequently the defect of unequal or excessive pressure as.
commonly applied to such rollers having downward adjustment by screws, is.
obviated.
The rollers 3. 3 may consist of india-rubber, or of close felt which forms a
durable and non-abraiding covering, especially for cleaning the flut handles of
forks or spoons, so likewise the burnishers 11. 13 are covered with close felt or
disce of buckskin; the one 11 is for use in cleaning the outsides of spoons, backs
of forks; the other 13 is for cleaning insides of spoons, forks, and the like, and the
brush 12 is for removing powder and cleaning between the prongs of forks, and for
other like use.
By constructing the machine in the manner described, there is no excessive
pressure on the rollers 3. 3, and consequently no flattening of either roller, and by
reason of the bottom roller having vertical movement occasioned by different
thicknesses of forks, spoons, and other articles, and the yielding action of the
springs 17. 17, there is consequent displacement and movement of the polishing
powder, and so the rollers 3. 3 are from time to time brought into contact with the
powder and obtain the requisite supply.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
(1.) The general construction, arrangement, and combination of parts constituting
the improved machine for purposes herein referred to, and as such machine is
herein described and illustrated by drawings annexed.
(2.) In machines comprising nip cleaning rollers such as 3. 3, the combination
therewith of cleaning devices such as 11 and 13, and as described herein and
illustrated by the accompanying drawings.
(3.) In machines comprising nip rollers 3. 3, spiral springs, moveable and moving
blocks 19, and stationary blocks 19 19, all in combination as and for the purposes
herein described, and as illustrated by the annexed drawings.
