I BENJAMIN PLOWMAN KENT, OF OUTLOOK, SASKATCHEWAN, CANADA.
MACHINE FOB HULLING- WHEAT.
'- Application filed June 27, 1924.
To all whom it may concern:
Be it known that I, BENJAMIN PLowMAN KENT, a subject of the King of Great Britain, and resident of the town of Outlook, in the Province of Saskatchewan and Dominion of Canada, have invented certain new and useful Improvements in Machines for Hulling Wheat, of which the following is a specification.
This invention relates to improvements in machines for hulling wheat and the objects of the invention are to provide a machine of this character that will leave the wheat practically free from creasedirt, fuzz and outer fibre, and in better condition to go to the rolls.
'Still further objects are to provide a ma chine of this character of efficient and durable construction that can be manufactured and placed on the market at a reasonable price and generally better adapted to perform the functions required of it.
With the foregoing and other objects in View, my invention relates to a machine adapted to beused for the preparatory treatment of Wheat after it hasbeen thoroughly cleaned, and before goingto the rolls for reduction to flour.
The machine consists essentially of an outer casing having a shaft centrally mounted therein on which a drum of rotary milling blades is carried, means being also provided for admitting water to the machine to temper the wheat and also means for discharging the whole product after being operated upon by the machine.
Referring now to the drawings in which like characters of reference indicate corresponding parts in each figure,
Figure 1 is a side elevation.
Figure 2 is a top plan view.
Figure 3 is an end view.
Figure 4 is a longitudinal section.
Figure 5 is a section on line 5--5 of Figure 4.
Figure 6 is an end view of the rubbing plates on end of drum.
Figure 7 is a plan view of one of the hulling blades.
Figure 8 is an enlarged section through one of the rubbing plates.
In the drawings 10 designates the head or end casting of the machine provided with a Serial No. 722,833.
being provided with suitable legs14,adapted through openings 15 to be secured in position.
Supported by these castings in an outer casing 16 having centrally arranged. therein a longitudinally extending shaft 17 provided with a driving pulley 18 at one end. It will thus be seen that the two castings form respectively one half the frame of the machine and are so formed as to accommodatethe shaft 17 journalled therein, and provided with suitable caps 19.
The outer casing 16 is preferably made of heavy galvanized iron and when in place its ends lap over circumferential flanges on castings 10 and 13, all being securely held by four horizontal rods thus completing the frame.
A water intake 12 is also provided in the form of a conical raised opening which may the water to pass through before it enters the machine. The casing 16 is also provided with a discharge spout 16 of galvanized iron or other suitable material and adapted to carry the wheat, after it is crowded up from the rubbing plates by the centrifugal force of the milling drum. At the top of the spout is attached a hinged lid 9, a heavy member and perfectly flat to close the dis charge spout opening entirely. This lid is controlled by a spring 8 which has an ad justable screw 7 to govern the pressure in operation and on the shaft being rotated the wheat is delivered through the hopper first. On the casing being charged and the water being admitted through the intake 12 the wheat passes to the hulling blades and from them to the rubbing plates arranged on the outer discharge end of the hulling drum and also on the discharge end casting, registering with said plates on the outside of the discharge end of the hulling drum, then as the wheat is operated upon by these plates it is delivered by the centrifugal force exerted by the hulling drum to the discharge spent 16.
Within the machine and on the shaft 17 is fixedly mounted a hulling drum 22 comprising two heavy cast flanged hub collars 23 with set screw 24 for attaching the drum solidly to the shaft 17, and on these flanges are securely riveted the boiler plate ends 25 "be provided with a grating or the like for y feed opening 11 to which is attached a feed spout 12. 18 is the other casting which is in all respects similar to the casting 10, both of the'drum. On the outside of the dis charge end of the hulling drum 22 are mounted a set of rubbing plates 26. The
head end plate of the hulling drum is similar to the discharge end except that rubbing plates are provided on the outer surface of the discharge end.
The hulling blades 27 are preferably made of heavy, woven, scouring case material and consist of two pieces) securely riveted to gether to make one blade. The cutting surface of the blades is on the outer side and their outer edges come in direct contact with the crease of the wheat berry as it circles endwise around the drum. The rubbingplates, on the other hand, are made from pressed steel sheets, and formed with faces having saucer-shaped indentures, therein.
In use and as illustrated in Figure l, a plurality of hulling blades are carried in the hulling drum, slightly spaced from one another and are hung in sets preferably about an inch apart on two horizontal rods 30 and 31 and are divided by cast iron washers 32. At each end of these rods is a nut 24F and by operating these nuts the points of the hulling blades may be moved to right or left. When moved slightly to the right it will cause the wheat to become much deeper between and around the hulling blades before travelling on to the rubbing plates at end of drum. Vhenmovedslightly to the left exactly the reverse will happen, and the hulling action will be less severe. This constitutes the adjustable feature of thehulling drum and is most important.
As many changes could be made in the above construction and many apparently widely diflerent embodiments of my invention, within the scope of the claims, constructed without departing from the spirit or scope thereof, .it is intended that all matter contained in the accompanying specification and drawings shallbe interpreted as illustrative and not in a limiting sense;
What I claim as my invention is: v
1. A. machine for hulling wheat, comprising a suitably supported outer casing,'a rotatable shaft journalled through said casing, a driving pulley on said shaft, a hulling drum within the casing and fixedly mounted on said shaft, a plurality of hulling blades on said drum, rubbing plates on the end of said drum and rubbing plates registering therewith on the inner end of the casing, intake and discharge means for the casing, means for adjusting the hulling blades and water intake means in the casing.
2. A machine of the character described, comprising a pair of castings, an outer cas ing supported by said castings, a shaft.
through said casing and supported by said castings, an intake hopper in onev of said castings and a. discharge spout in the casing, and awater intake in the casing, rubbing plates carried by one of said castings, a hulling drum comprising a plurality of spaced, adjustable hulling blades carried by said shaft within the casing and means'for rotatingsaid shaft.
3. In a machine as described in claim 2, in which the'hulling blades are formed in two sections mounted on rods in spaced relationship to one another and having washers therebetween and adjusting nuts on said rods whereby the blades are moved apart or close together. c I,
4. In amachine as described in claim 2, a plurality of ,rubbing plates fixedly mounted on the outer end of the hulling drum and similar plates adapted to register with the afore-mentioned plates on one of said castings, whereby on the wheat passing from the hullin blades it is operated upon by said rubbing plates. 1.
5. In a machine of the character'idescribed in claim 2, a hulling blade of Woven material fo'rmed'of two pieces riveted together and having a'cutting surface on the outer side adapted to fit around a hulling drum.
In Witness whereof I have hereunto set my hand. I
BENJAMIN PLOVVMAN KENT.
