I, WILLIAM FREDERICK MASON, of Longsight, Manchester, Engineer, do hereby
declare the nature of this invention to be as follows:-
The improvements relate to dough-kneading machines, and have for object the
tilting of the trough by mechanical means.
To accomplish this and to effect my improvements, I mount the trough in journals
by means of shafts attached to each end, and to one of these shafts is affixed a worm
wheel or quadrant. This is actuated by means of a worm upon a shaft running at
right angles to the motion of the trough, and holds the same in such position as is
desired. The other end of the worm shaft is fitted with a friction wheel,-by
preference bevil in form, but other forms may be employed, and this is mounted in
bearings which places the friction wheel in position to be acted upon by two other
bevil or other formed friction wheels, which are upon the main driving or counter
shaft for the purpose.
These latter wheels are capable of being slided upon the shaft, so as to be brought
in and out of gear, by means of suitable mechanisms actuated by hand lever or other
means, and as they are placed one on each side of the worm shaft friction wheel this
shaft is caused to be turned either one way or the other, as one, or another of the
driving friction wheels is brought in gear, and thus actuates the tilting of the trough
in either direction as required.
Variations may be made in the details, such as the employment of friction discs
acting upon a plain wheel, or of cones, with any form of hand mechanism for
actuating the same, without departing from the peculiar character of the invention,
which consists in the employment of friction mechanism actuating a worm shaft for
the purpose of tilting the trough in dough-kneading machines.

page_text: moveable journal 7, 1, is fitted either in a slide, or, is attached to the framing at a
fulcrum point only, around which it is free to turn or take slight motion, and held in
position & governed by the rod or shaft kk. By this means the bevil friction wheel
on the worm shaft may be brought in gear with the wheels f, f, or f', f, at will, so as to
operate such worm shaft in either direction, according as one or other of the bevil
wheels on the shaft is brought into gear with that on the worm shaft, or it is brought
into gear with them.
?
This shaft h, h, carries the worm h³, h, which gears into the toothed wheel or
portion of a wheel m, m, and as this is keyed or otherwise attached to the shaft
carrying the trough, the same may be automatically tilted to any degree or angle.
Instead of the worm shaft being caused to oscillate for the purpose of bringing
the friction wheels into gear, the same may turn in fixed journals, and the wheels on
the shaft may be moved in and out of gear by sliding upon the shaft, or the shaft may
slide in its journals with or without the trough bodily.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is :-
The employment of friction mechanism actuating a worm shaft for the purpose of
tilting the trough in dough-kneading machines in manner substantially as shewn and
described.
