I, JACOB BELL HOLGATE of 1, Junction Street, Burnley, in the County of Lancaster,
Miller, 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 machine, in which these improvements are embodied, comprises several new and
useful devices, whereby the conveying properties of the machine are increased; the
cost of construction of the parts and the liability of such parts of the machine to
derangement are considerably reduced; less friction and consequently a reduction of
power is ensured.
And in order that my invention may be properly understood, and readily carried
into practical effect, I have hereunto attached the accompanying sheet of drawings,
marked with figures and letters of reference, the same letters referring to the same, or
corresponding parts, in the various figures. Fig. 1 represents a side elevation, Fig. 2
a plan, and Fig. 3 an end elevation, in section, of a machine, for conveying substances,
constructed in accordance with my invention, Figs. 4 and 5 are detached views of
the apparatus or machine. A is a trough like receptacle, in which the material to
be conveyed is placed. Within this receptacle is mounted a traversing frame B,
preferably constructed of metal in tubular form, to combine strength with lightness.
From the traversing frame B projects stud C, connected by arm D to crank E,
secured to shaft F, to which is also secured driving pulley G.
To reduce the power and friction in driving the machine, the traversing frame B is
mounted upon anti-friction rolls, distributed at suitable distance apart. These rolls
may be of a form similar to roll H, seen in Figs. 1, 2 and 3, which are capable of
traversing to and fro in the longitudinal slots 1, at the sides of the trough like
receptacle A; or, rolls J, seen in Fig. 6, may be substituted for roll H, and may roll
or traverse the longitudinal strips K, secured to sides of receptacle A.
These rolls having no axle or stud bearings require no lubrication, renders the
machine particularly applicable for conveying such material as flour grain, or the
like, as the objectionable feature of grease lumps, appearing in the material conveyed,
is altogether avoided.

page_text: From the traversing frame B are suspended, in steps L, blades or flaps m, which,
traversing with the said frame in the direction of the driving shaft F, are raised, as
seen in dotted lines in Fig. 4, when riding or trailing over the substance to be
conveyed.
Upon the return movement of the traversing frame and the blades or flaps, the free
ends of the latter penetrate the material, pushing it forward the length of the frame's
traverse where such material is left to be pushed forward another length, on the next
return of the traversing frame and blades. The substance to be conveyed is thus
pushed intermittently, step by step, through the trough like receptacle A.
To prevent the lower ends of the blades or flaps in from trailing on the hottom of
the trough like receptacle, they are arrested in their descent, as seen in Figs. 1, and 4,
by stop piece n, attached to step L, or other suitable part of the traversing frame,
against which they rest, while pushing the material through the trough like receptacle.
The steps L are each provided with a projecting lip O, which is inserted in the hole
of the bracket P, as seen in Fig. 5, to which it is secured at the time of fixing the
said bracket to the traversing frame B, by set screw S. The direction may be
reversed, in which the material is to be conveyed, by simply reversing the stops Land
blades or flaps m from one side to the other of the bracket P, and without removing
the latter from the traversing frame B.
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. The frame B mounted on rolls E. or J substantially as described.
2. The blades or flaps m, stop piece n, bracket P, and reversable step L.
3. The general arrangement and combination of parts constituting a machine or
conveyor for conveying substances, substantially as described.
