The method usually pursued in attaching bolting cloths to reels is clumsy and inefficient, being by means of tacks, which tear the cloth, and will never keep it at the same tension or tightness aU around the bolt. It is extremely troublesome to remove, and should any portion get tom or damaged it cannot well be repaired, so the millers usually paste up the hole, whieh helps to clog the bolt, and prevent its perfect action. The method of attaching cloths to reels, which is the subject of our illustration, is the invention of John Woodville, of Chilicothe, Ohio, and was patented by him April 21, 1857. Fig. 1 is a perspective view of a bolt, A be-1 ing the central axle, with journals, a, on . which it cnn rest, and from the axle projects 3 two or morc scts of radial arms, B, that carry the slats, C, which run parallel with the axle from the reel. Each of these slats, C, has two semi-circular grooves in it, c, and there fits on the top of each of them another slat, D, having corresponding semi-circular grooves; C and D, being secured together by square headed screws, E. At one end of the bolt, plates, F, pass between the slats, giving rigidity to the reel, and helping to hold the cloth (seen in Pig. 3). They are attached to a rim with which that end of the reel i. provided, by screws, e, passing through a slot in the metal plate, f, that is on the wooden plate or piece, F. G are the cloths, each of which, whether of silk or fine wire gauze, should be bound with canvas to protect the edges and ends. The canvas of one of the long sides is stitched round an iron or other rod, which, being inserted into the semi-circular groove in C, and thA plate, D, screwed down tight over it, holds the bolting cloth perfectly rigid at one side. The other side is now passed round a loose rod, H (seen in Fig. 2), which is placed in the nearest groove, c, of the next slat, and the cloth being pulled tight round it, the slat, D, (having first a side of another cloth placed in its other groove,) is partly screwed down, and the cloth can be pulled to any desired tension by the projecting slip, g ; but when D is once thoroughly screwed tight it will not move. The ends nrc now pulled " taut," and the piece, F, secured, and the bolting cloth is fixed. In this way the whole reel is quickly made up. This system has been in use some time, and has fully ans,vered the inventors' expectations, giving, by the evenness of its surface, a superior bolting reel, and being easily repaired, cleaned, or adjusted. We recommend it to the notice of every miller. Any more particulars can be obtained from the inventor, as above.
