Improvements connected with Gearing, applicable for Knife Oleaners
and other Machines.
1, JAMES WILLIAM SPONG, of 226 High Holborn, London, Manufacturer of
Domestic Appliances do hereby declare the nature of my said invention to be as
follows:-
The object of my invention is to arrange or connect gear wheels, friction wheels
or pulleys in such a manner that the two outside wheels may be adjusted to suit
varying positions between same, and at the same time be in gear through one or
more gear wheels.
As an example of my invention I will describe it as applied to a knife cleaner
of the roller type but it is equally applicable to all kinds of machinery where two
wheels, rollers or other revolving body have to be adjusted in relation to each
other and where the motion of one is communicated to the other through pinions
or similar appliances.
To each of the axles of the two rollers of a knife cleaner, I attach a pinion
and having in gear therewith another pinion, this pinion being connected to each
axle of the knife cleaner by a strap or bar and not to a fixed point of the machine
as at present, this allowing the centro pinion to be always in gear at whatever
position the two rollers may be adjusted to.

COMPLETE SPECIFICATION.
Improvements connected with Gearing, applicable for Knife Oleaners
and other Machines.
I, JAMES WILLIAM SPONG, of 226 High Holboru, London, Manufacturer of
Domestic Appliances, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described nud ascertained
in and by the following statement :—
The object of my invention is to arrange or connect gear wheels in such a
manner that the two outside wheels may be adjusted to suit varying positions
between samne, and at the same time bo in gear through one or more gear wheels.
As an example of my invention, I will describe it as applied to a knife cleaner
of the roller type but is equally applicable to all kinds of machinery where two
wheels, rollers, or other revolving body have to be adjusted in relation to each
other and where the motion of one is communicated to the other through pinions
or similar appliances.
To each of the axles of the two rollers of a knife cleaner, I attach a pinion and
having in gear therewith another pinion, this pinion being connected to each axle
of the knife cleaner by a strap or bar and not to a fixed point of the machine as
.

page_text: at present, this allowing the centro pinion to be always in gear at whatever
position the two rollers may be adjusted to.
I have in the annexed drawings, Figure 1 end elevation, Figure 2 front elevation,
abown which is known as the "Uneek" Knife Cleaner consisting of a frame A
affixable to a table, bench, or other like support by the pinch screw B. The knife
blade cleaning surfaces C, C, are of leather discs or rings clanipel upon axles D, D',
by screw collars E, E, one of said axles D being of greater length than the other
for additional cleaning discs F for operating upon the shoulders or hollows of the
inner ends of the blades, these discs being arranged of different diameters to quit
large and small knives.
The axles D, D', of the two cleaning rollers C, C, are genred to run in the
same direction to prevent the blades of the knives being drawn in by the nip put
upon them, this is effected by a loose pinion G carried by straps or links H, H,
suspended from both the axles D, DI, said straps or links otherwise embracing
the pinion G by their connection with the axles D, D', and the axle I in order
that when the two cleaning rollera C, C, are moved apart by the thickness of the
knife blade plared between them, their axles D, D', by being further separated
draw the outer ends of the links H, H, farther apart and consequently the inner
or coupled ends with the pinion G inwardly, the teeth of the three wheels G, G', G',
remaining in gear for the transfer of rotary motion from, say
the upper
axle D
(operated by the handle J) to the lower axle of the two cleaning rollers C, C, by
the wheel G.
The machine shown on the drawings is the invention of and is patented by
Mr. J. O. Spong, No. 9567 of the year 1895, and I make no claim thereto in my
specification but what I do desire to protect is:-Tho loosely hung straps or
links for suspending the intermediate or idle pinion which on being drawn nearer
to or pushed farther from each other maintain the contact of tho gear without
regard to the thickness of the knife blade inserted between the cleaning rollers.
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 :-
1. Suspending an intermediate or idle pinion G by links H, H, from axles D, D',
of main pinions G', G³, as and for the purpose set forth.
2. In combination with two gear wheels G', G', a pinion G whose teeth shall be
always in gear therewith by loose connections H, H, attached to or hanging from
the axles D, D¹, of the two gear whools G', G³, as set forth and substantially as
represented in the annexed drawings.
3. The hereinbefore described improvements in the goaring of kuife cleaners of
the kind indicated and as and for the purposes described.
