BOLT ING MACHINE Filed Sept. 24, 1955 Patented Dec. 7, 1937 I PATENT oFFicE H BOLTING MACHINE Edward Schultz, Evansville; Ind.
Application September 4 Claims.
This invention relates to an improved bolting or screening machine and has for an object an improved bolting machine for graduatingcracked grains of any kind into various degrees of fineriess and coarseness. A further object. of this invention is to provide an improved bolting machine wherein the cracked grain or wheat enters at one side, passes across screens of gradually increasing mesh .so as to :discharge the cracked grain into suitable receptacles according to its 7 across the sifting screen by means of a rotatable brush the. arms of which are adjustable so as to compensate for wear.
An additional feature is an adjustable mechanism for cleaning the brushesas they rotate, which mechanism may be adjusted to clean a greater or lesser section of the brushes, thus increasing or decreasing the available effective brush area and thus the speed with whichthe material being bolted may flow across the screen.
With the foregoing and other objects in view, as will hereinafter become apparent, this invention comprises the constructions, combinations, and arrangements of parts, hereinafter set forth, claimed, and shown on the accompanying draw- In this drawing,
Figure 1 is an elevational broken away view of the machine.
Figure 2 is a section on line 2-2 of Figure 1.
Figure 3 is a section on line 3-3 of Figure 2, and,
Figure 4 is a section on line 44 of Figure 2.
There is shown at H] the bolting machine of this invention. This bolting machine Ill includes a housing ll having an entrance side 12 and an exit side I3.
Journaled through the sides I2 and I3 is a brush shaft l4 having a power receiving pulley [5 at one end thereof adapted to be operated by an endless belt from any suitable source of power. Fastened on the shaft M as by set screws l6 are a pair of spiders ll having a plurality of arms l8, four arms being provided in this particular case. The arms of each spider are fastened to the shaft so that the arm of one spider is in the same plane with the arm of the other spider thereby enabling a long horizontal brush 19 to be adjustably secured as at 20 on the aligned arm of the spiders.
The housing II is divided into a plurality of grain receiving compartments 22, 23, and 24 and 24, 1935,. Salem. 41,909
The inlet channel extends centrally into a compartment 29 thru the side l2 while the outlet channel 3! extends through the side 13 adjacent the bottom of the brush compartment 29. A valve 32 held closed by light weight 33 tends to provide some resistance to the passage of the grain from thecompartment 29 to the outlet 3| so as to give the grain an opportunity to be brushed against the mesh of the screen before it is discharged.
The upper end 34 of the housing H is formed into a cylinder concentric with the cylin-derdefined by the screens 25, 26, and 21, but of slightly larger diameter. The brushes I!) are adjusted on the spider arms l8 so that they will justbru'sh against thescreens 25, 26, and 21 as shown'in Figure 3 and hence will not contact the inside of the cylinder portion 3| of housing H thus properly agitating the grain as it passes: from the inlet 30 to the outlet 3|. In order to clean the fibers of the brushes l9 as they rotate, a plurality of cleaning blades 35 extending thru cylindrical portion 34 of the housing II on stems 36 into the path of the brushes. l9 and clean the brushes as they rotate.
These stems 36 of the cleaning blades 35 are each provided with pitmans 31 journaled at 38 to a control rod 39. At one end, the control rod 39 is provided with a control handle 40 having a plurality of notches 4| so as to cooperate with a finger 42 and thus hold the cleaning blades 35 at any desired angle.
In operationthe cracked grain or wheat enters the compartment 29 thru the inlet 30 and is agitated by the rotating brushes l9 over the successively coarser sieves 25, 26, and 21, the finest cracked grain falling into the compartment 22, next into compartment 23, and the next into compartment 24. That part of the grain which is too coarse to be discharged thru any of the sieves finally works its way to the outlet 3| past valve 33. As the blades rotate the fibers are cleaned by means of the cleaning blades 35, the angle of which may be adjusted by shifting the control handle 4|].
The novel features and the operation of this device will be apparent from the foregoing description. While the device has been shown and the structure described in detail, it is obvious that this invention is not to be considered limited to the exact form disclosed and that changes may be made therein within the scope of what is claimed without departing from the spirit of the invention.

1. A grain bolting machine comprising a housing, a fixed screening means of increasing mesh dividing said housing into an upper agitating compartment and a plurality of lower receiving compartments, partition means separating said lower compartments from each other, a grain agitating brush journaled in said upper compartment, a grain inlet conduit leading into said agitating compartment, a grain discharge conduit leading from the lower edge of said upper agitating compartment, a weighted valve pivoted at the entrance of said discharge conduit, and a plurality of adjustable cleaning blades in said agitating compartment in the path of rotation of said agitating brush. 2. A grain bolting machine comprising a housing, a fixed screening means of increasing mesh dividing said housing into an upper agitating compartment and a plurality of lower receiving compartments, partition means separating said lower compartments from each other, a grain agitating brush journaled in said upper compartment, a grain inlet conduit leading into said agitating compartment, a grain discharge conduit leading from the lower edge of said upper agitating compartment, and a weighted valve pivoted at the entrance of said discharge conduit, said screening means being in the form of a semicylinder concentric with the axis of rotation of said agitating brush and having a radius slightly less than the radiusrof said brush whereby said brush will agitate the grain thereagain, the top of the housing forming the agitating compartment being of semi-cylindrical shape concentric with the axis of rotation of the brush but having a radius greater than the radius of the brush.
3. A grain bolting machine comprising a housing, a fixed screening means of increasing mesh dividing said housing into an upper agitating compartment and a plurality of lower receiving compartments, partition means separating said lower compartments from each other, a grain agitating brush journaled in said upper compartment, a grain inlet conduit leading into said agitating compartment, a grain discharge conduit leading from the lower edge of said upper agitating compartment, and a weighted valve pivoted at the entrance of said discharge conduit, said brush including 'a shaft, a pair of spiders, one spider being secured to said shaft adjacent each end of the shaft, said spiders including a plurality of outwardly extending arms, the arms of each spider being secured in common planes, and a plurality of brushing arms, each brushing arm being adjustably secured on the pair of spider arms in the common plane.
4. A grain bolting machine comprising a housing, a fixed screening means of increasing mesh dividing said housing into an upper agitating compartment and a plurality of lower receiving compartments, partition means separating said lower compartments from each other, a grain agitating brush journaled in said upper compartment, a grain inlet conduit leading into said agitating compartment, a grain discharge conduit leading from the lower edge of said upper agitating compartment, a weighted valve pivoted at the entrance of said discharge conduit, said brush including a shaft, a pair of spiders, one spider being secured to said shaft adjacent each end of the shaft, said spiders including a plurality of outwardly extending arms, the arms of each spider being secured in common planes, a plurality of brushing arms, each brushing arm being ad justably secured on the pair of spider arms in the common plane, a plurality of angularly adjustable cleaning blades for said brushing arms in said upper compartment, stems for said cleaning blades extending thru the sideof said upper compartment, a control rod, a plurality of pitmans securing said stems to said control rod and a control handle on said control rod for adjusting the angle of said cleaning blades in contact with said brushing arm.
