Rotary Flour Bolt.
1, LEVI HERTZLER, Gentleman of Mechanicsburg Pennsylvania, Kingstreet 20
United States of America, do hereby declare the nature of this invention aud
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-—
The object of this invention is to produce novel means whereby the stock is
discharged from the ribs in their descent in an even and gradual manner
overcoming the objections so prevalent in bolts in common use where the rear
surface of the rib is flat. Furthermore in so forming the integral carrying board
of the rib that it extends outwardly from the main portion of the rib with its
surface greater than a right angle with relation to the rib proper.
A further object of the invention is to provide mechanism which will knock
or vibrate the screens and prevent the meshes thereof from filling; further-
more to provide means for securing or releasing the knocker at the will of the
operator.
With these and other objects in view, the invention consists in the novel details
of construction, arrangement and combination of parts to be hereinafter more
fully set forth and specifically pointed out in the claims.
In describing the invention in detail reference is had to the accompanying
drawings forming part of this Specification, wherein like characters denote
corresponding parts in the several views, in which,
Fig. 1, is a view in perspective of a bolt with the outer cloth removed,
Fig. 2, is a view in perspective of the knockers and their securing mechanism,
Fig. 3, is a view in perspective of a section of a rib showing the rear face
beveled.
In these drawings, A, denotes the shaft, B, the spider, C, the arms secured to
the spider and carrying on the ends ribs D, and the ribs in turn forming supports
for the bearings of the rod which carries the arms for securing the knocker, (to be
bereinafter referred to).
The spiders B, are provided with apertures b, to receive the rods 6', which pass
through the eyelets, in the knocker arms, said arms extending radially there-
from. By this means the knocker arms are secured in place by and are pivoted
on the rods b'. The outer ends of the knocker arms are connected by a wooden
piece, which, with the arms and rod form the knocker frame. The bearing
posts d', are secured to the ribs D, and the rods &, are mounted to rotate therein,
said rods being provided with integral extensions 66, which are curved, to fit around
the connecting piece 6, of the knocker, and secures said knocker in place against
action.
A plate 67, is secured on the head of the bolt and is provided with a semi-
circular groove to receive the thumb screw 68, which is secured in the head of the
bolt, and connected with the rod 6, for the purpose of adjustment.
As shown in Fig. 2, the knocker is held to the ribs, and in dotted lines the arms
are shown elevated out of engagement with the knocker frame. The operation of
the device will be understood from the foregoing.
Each of the ribs D, has its rear face oppositely beveled as at d', d², while the
opposite face is provided with an extension beveled at an angle approximating
60 degrees, with relation to the main section of the rib.
By thus increasing the bevel of this extension which forms the pocket, as the
ribs pass upward the pockets are filled and the discharge therefrom will commence

page_text: before the rib reaches the top and it will continue gradually to discharge until
empty.
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. A rotary bolt provided with ribs having the rear edges beveled, substantially
as described.
2. A rotary bolt provided with ribs having their rear edges beveled and having
an extension from its front surface beveled at an angle greater than a right angle,
for the purpose described.
3. A rotary bolt provided with a reel having knockers and means for securing
and releasing said knockers, for the purpose described.
4. A rotary bolt provided with knockers, bearing posts secured to the ribs, a
rod mounted to partially rotate thereon, curved extensions on the rod and means
for moving the extensions into and out of contact with the knocker, for the pu pose
described.
5. A rotary bolt provided with knockers, bearing posts secured to the ribs of the
bolt, a rod mounted to partially rotate thereon, curved extensions on the rod and
means for moving the extensions into and out of contact with the knocker and
securing the same in its adjusted position, as and for the purpose described.
Dated this 23rd day of September 1895.
