Our bolts are so well known that a full description seems superfluous. Their constant use for fourteen years has suggested some marked changes, which together with a brief outline of the bolt itself, we will describe. The object gained is a more efficient bolt for custom work, either for a Portable Mill or any flouring mill however large or small, where a bolt is wanted specially adapted to the demands of custom grinding; at the same time a bolt that can be shipped to any point on a navigable river or railroad in the United States or Territories. We have already sent a number of them into Northern Minnesota and Wisconsin. Also, Texas, Kansas, Georgia, &c., &c. When so ordered they are taken apart and boxed, previously marked how each part belongs, and drafts and description of how to set it up, sent so that one at all skilled can put it up in the mill and have it ready to run in two to three days time. For those residing within a few hundred miles of our works, we mostly send on open cars or boat, well protected by paint and varnish, and out of the great number shipped within ten years past, have not had a single one at all damaged that we know of. They are made in large quantities, the parts being duplicated and cut out from patterns, and by machinery adapted to the purpose. The lumber contained in them is thoroughly seasoned, and selected of the best quality. The parts usually sent with them unless otherwise ordered are: 1st. All the gearing and shafts required, with supporting frame and bearings for the elevator head, spout, gear and shafts. 2d. Extra heavy cloth of Dufour & Co.’s Dutch Anchor brand made up to fit the reel, with strips of ticking to come in contact with the ribs of reel, and proper arrangement of numbers to make flour that will bear inspection. This is generally sent by express in a separate package. 3d. The elevator complete, as follows: forty feet of 4½-inch leather or gum belt, thirty 4-inch heavy tin, iron banded, cups, with improved copper clasp fastenings, head and foot with turned pulleys in them, including an outside pair of bevel or spur wheels or turned pulley to receive power. (See cut of elevator head and foot under head of “Elevator, Cups and Fastenings.”) 4th. A cooling conveyor geared by suitable wheels to the shaft in foot of the elevator, so that it can be located in any direction to suit the situation. To fill some special orders we have put the cooling conveyor on top of the chest; in most cases it is best to have it below. The frame work of the bolt is made of hard wood and well bolted. Conveyor for flour and one for returns full length of bolt; conveyor flights are of hard wood; cut offs are provided so that one-fourth, all or any degree of the flouring cloth may be used for fine flour, at the option of the miller.
