Description

UNITED STATES BENJAMIN O. WHITE, OF DES MOINES, IOWA.
IMPROVEMENT IN MILL-BOLTS.
Specification forming part of Letters Patent No. 120,137, dated October 17, 1871.
To all whom it may concern: A
Be it known that I, BENJAMiN O. WHITE, of Des Moines, in the county of Polk and in the State of Iowa, have invented certain new and useful Improvements in Mill-Bolts 5 and do hereby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawing and to the letters of reference marked thereon making a part of this specification.
The nature of my invention consists in the construction of a mill-bolt, as will be hereinafter fully set forth.
In order to enable others skilled in the art to which my invention appertains to make anduse the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure l is a transverse vertical section of a bolt-house with my improved bolt. Fig. 2 is a longitudinal vertical section of the head of the reel, and Fig. 3 is a sectional view of a portion of the bolt.
A represents the bolt-house, which may be made in any of the known and usual ways. B is the reel-shaft, from which the rods C C radiate, supporting` the ribs D D. This bolt-reel is made in sections of any number and of any diameter required. By making it in sections I mean that the reel is so constructed that when it is all put together ready for use two ribs can be removed at a time, stretch the cloth on them, and put that section back to its proper place on the rods or spokes of the reel, and then remove the next section to put on the cloth 5 and so on until all are clothed, and the ribs screwed together firmly, and the reel is ready for use. The bolting-cloth is put on the inside of the ribs of the reel all round; or, in other words, on the inside of each and every rib all round the reel, and the whole length of the reel, if necessary.
Putting the cloth inside ofthe ribs ofthe bolt reel leaves the meal or chop to slide smoothly over the cloth, besides getting more cloth surface, as there are no ribs in the way to carry the chop almost to the top of the reel, causing specks to drop through the cloth by the heavy concussion.
With my improved mode of putting on bolting-cloth I can make an evener grade of flour and at least two shades whiter out of the same grade of wheat, and make from three to four pounds of No. 1 flour more to the bushel of wheat, and scarcely any middlings for second grinding.
At the head of the reel the ribs D D are curved, as shownin Fig. 2, the cloth being stretched on the inside of the curved portion of the ribs as well as on the straight portion. This is a decided improvement over the old straight-ribbed reel, as it receives the chop or meal with less dusting back, and carrie-s the chop forward into the bolt with greater ease. The friction is also lessened by using a much smaller flange or head. The head end of the reel-shaft B passes through a circular conveyor-box or spout, E, and is provided with a sorew-iiange, I. The box or spout E receives the chap or meal from the elevators, and the screw I conveys it into the head of the reel and distributes it evenly on the cloth. The conveyer-box or spout E may be either square or round; but I prefer the round spout, as that is best for many reasons, one of which is a sheep skin packing, marked a, fastened on the inside of the reel-head all around next to the conveyerbox. The sheep-skin of which this packing is made should have the wool on and placed so as to rub against the box or spout to prevent any dust or specks from escaping through the reelhead around the box.
Having thus fully described my invention, what I claim asnew, and desire to secure by Letters Patent, is,-
l. In a Hour-bolt the ribs D, when curved and converging at the head of the reel, substantially as and for the purposes set forth.
2. The combination of the shaft B, radial arms (l, converging bisected ribs D, and bolting-cloth box E and conveyer I, all constructed and operating substantially asset forth.
3. The packing a, attached, as ldescribed, on the inside of the head of the reel and operating on the outside of the box or spout E, substantially as and for the purposes herein set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 17th day of December, 1871.
