Mechanician do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:—
The object of my Invention is to provide a new and improved machine, for
kneading and working dough and other similar parts.
The invention consists in the construction and arrangement of parts, as will be
hereinafter described and claimed.
Reference being had to the accompanying drawings, forming a part of this
specification, in which similar letters of reference indicate corresponding parts in
all the figures.
Figure 1. is a cross sectional elevation of my improved dough-kneading machine
on the line - Fig. 2. Fig. 2. is a longitudinal sectional elevation of the same
on the line y y Fig. 1. Fig. 3 is a detail view of part of the revolving frame
carrying the blades. Figs. 4 and 5. are perspective views of the beater-frame.
Through the ends of a hollow cylindrical drum, A, the shafts B are passed, which
are journaled in boxes O¹, formed on the upper ends of plates C, arranged to slide
vertically in uprights D, held on the end-supporting frame E on a base F. A cam
lever, F, is pivoted to each upright D, and the upper cam ends of the levers rest
against the journal-boxes C', the lovers projecting downwards as shewn.
On the outer end of each shaft B, a cog-wheel, G is mounted, which wheels
engage with pinions H on a shaft, J, journaled parallel with the drum on the
frames E.
On the inner ends of the shafts B a quadrilateral frame, K, is secured in such a
manner that it can revolve in the drum. This quadrilateral beater-frame K is
composed of end bars, K', beveled in opposite directions above and below. their
centres, and cross bars M M M M, that connect the end bars near their ends.
Each pair of cross bars M are in practice placed about four inches apart, thus
The
leaving the central part of the frame open, and clear of obstruction.
beveled surface of the end-bars, K³, on one side of the centre are provided with
blades L, projecting beyond the outer edges of the end bars, in order to scrape off
dough that may adhere to the ends of the cylinder carrying it inward.

One cross-bar M of the frame uniting the end bars has apertures N for receiving
lugs O, projecting from a blade, P, held on the said slide bar adjacent to the inner
surface of the drum. Binding screws Q on the said bars hold the lugs O securely
on the bars M.
•
Curved flanges R project from the inner sides of the frames E in such a manner
that they can support the drum. The drum has openings S, which can be closed
by suitable gates.. A box, T, mounted on wheels serves to receive the kneaded
dough.
The operation is as follows:-The yeast, flour, etc. are placed in the drum A,
which rests upon the projections or flanges R, and the frame K is revolved in the
drum. The frame K and bars M, passing through the dough, work it. The dough
is pressed against the ends and inner surface of the drum and is again scraped off
by the blades P and L. The boxes C are then raised by means of the levers F,
whereby the drum is raised off the flanges R and can be turned on the shafts B so
that the openings S will be at the bottom and the worked dough can drop through
the said openings into the box, T.
The openings in the drum are large and extend the entire length of the same, so
that the attendant can see the dough drop and can watch the operation of the
machine.
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:
1. In a dough-kneading machine, the open beater-frame K, consisting of end
bars, connecting cross-bars, a transverse scraper having lugs passed through
apertures in a cross-bar at one end of the frame, and set screws for adjusting
and holding said scraper at any desired point, the said end bars being provided
at that side of their centre opposite the transverse scraper with scraping-edges
projecting laterally beyond the outer edges of the opposite half of the said end
bars, substantially as described.
2. In a dough-kneading machine, the combination, with a supporting frame a
cylinder resting thereon having a door or opening, and means for raising the
cylinder, of a beater-frame within the cylinder and shafts secured to the beater
frame for operating the same, and passed through the ends of the cylinder,
whereby the dough may be kneaded by the beater and the cylinder raised and
rotated to discharge the dough through its opening, substantially as set forth.
3. The combination of the frame E, uprights D, plates C, sliding, therein and
bearings on the plates C with the cam levers F¹, adapted to raise the plates and
their bearings, the vertically-movable dumping-cylinder A, supported by frame E,
the beater-frame within the cylinder, and the shafts B, secured to the ends of the
beater-frame for operating it, and passed through the ends of the cylinder and
through adjustable bearings C¹, whereby the cylinder and its contents and attach-
ments will be raised vertically from the frame with the plates C by the cam levers,
substantially as set forth.
