DEVICE FOR TIGHTENING BOLTENG- CLOTH.
SPECIFICATION forming part of Letters Patent No. 309,4:97, dated December 16, 188%.
Application filed Februarylfi, 1884. (N0 model.)
To aZZ whom, it may concern:
Be it known that 1, CHARLES A. SMITH, a itizen of the United States, residing at J ackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Devices for Tightening Bolting- Cloth, of which the following is a specification, reference being had therein to the accompanying drawings.
Figure 1 is a side elevation of a flour-bolt containing the invention. Fig. 2 is an end elevation, partly broken away. Fig. 8 is an elevation of the opposite end of the reel, partly broken away. Figs. 4. and 5 are detailed views. Fig. 6 is an end elevation, showing the invention as applied to a many-sided reel.
In the drawings, A B are the reel-heads, which may be of any usual or approved construction, although in this instance they are shown as being provided with central hollow trunnions, such as are commonly used in that class of bolts known as centrifugals. O is the bolting-cloth.
Referring to Fig. 2, 1) represents a strip, binding, or extension of the bolting-cloth, which in this instance consists of a narrow sheet or strip of stout woven fabric of double thickness stitched at its edges to the edge of the bolting-cloth. E is a circular tightener, which in this instance consists, essentially, of a hoop-like wire or small red, turned up at its ends to form ears 0 e, which are perforated to receive a tightening-bolt, E, cz'rrrying at its threaded end a nut, c, and at its opposite end a head, which prevents the bolt from passing through the ear in which it is supported. This circular tightener is seated in the fold of the fabric 1), and it will be readily understood that by turning the nut e in the proper direction the two ears 0 a can be made to approach, and thus reduce the diameter of the circular tightencr E and draw the bolt-cloth over the edge of the reel-head and toward its center.
Under many circumstances it will be found desirable to construct the reel-head B with a concentric flange, 1), against which the circular tightener shall bind the fabric D; and when it is desired to mount the reel upon anti-friction rollers F, as is sometimes done, it may be provided with a second flange, b, ofsomewhat less diameter than the flange b. By providing the reel-head with the two flanges b b the rollers F can rotate in contact with flange or rim 6 without danger of their running upon the drawn-over edge of the cloth, should they become loose, the step between the two flanges keeping the rollers upon their proper way or rim.
Referring to Fig. 3, D is a strip of fabric, doubled and attached by its edges to one end of the bolting-cloth. F is acircular tightener, provided at one end with a head, f, and at its opposite screw-threaded end with a nut, f. G is a metal plate, attached to the fabric D by rivets g g or otherwise, and provided at its lower or inner end with a seat or groove for the reception of one end of the tightener, the seat or groove being of such size that the tightcner may move freely through it. The other end of the tightencr is also supported by the plate G, and in this instance is shown as passing through and resting in a groove or seat formed in one or both legs of the plate, between the screw-threaded end of the tightener and the rivets y 9; but it is not intended to limit the invention to the precise construction of parts shown, it being apparent that one end of the tightcner might be riveted or otherwise firmly attached to the plate G, the threaded end being free to move relative to the plate without departing from the spirit of the invention. WVhile in the construction shown the plate is formed of a thin sheet or strip of metal doubled upon itself and riw eted at f/ g and 5 yet it (the plate) might be made of cast ,metal, with projecting lugs or cars for the reception of one end or both ends of the circular tighteuer.
In Fig. 6 the invention is shown as applied toa many-sided reel, in which instance it may be found preferable to cut the fabric H in the form shownthat is to say, with its outer edge or periphery many-sided, to correspond substantially with the outline of the reel, its inner edge, when doubled, being substantially circular, because this form will facilitate pro ducing a uniform tension upon the bolting cloth, as will be readily understood without further explanation. Of course in this instance the reel may be of any usual or approved constructionas, for instance, with a central shaft, spokes radiating therefrom, 1ongitndinal bars attached to the spokes, an encircling hooprim at the discharging end, with a centrally open head at the receiving end. It 5 is not necessary that the plate or its equivalent should be attached to the fabric D, because the device will operate satisfactorily under many circumstances, even if the plate be connected direetl y only to the circular tight- 'ener, although the construction shown is believed to be the preferable one for use under ordinary circumstances; nor is it essential to the working 'of the invention that the parts D D, or either of them, should consist of a fabric separate and apart from the boltingcloth, because under many ci'rcui'nstances the cloth can be hemmed, the fold being of such depthas to provide a seat for the circular tightener, although'it is probably better to employ ticking, canvas, or similar material for these parts D D, one or both of them.
What I claim is- 1. In a flour-bolt, the combination of the reel-head B, provided with the flange b and I the smaller flange b, which forms a rim for friction-rollers, the bolting-cloth extending longitudinally of the reel and turned over the edge of the reel-head toward the center, the circular tightener connected to the turnedover end of the bolt-cloth, and means for gripping the tightener and the bolt-cloth upon the flange Z), substantially as set forth.
' 2. In a flour-bolt, the combination of the reel-head A, the bo1t-cloth extending longiof the reel-head and toward its center, the circular tightener connected with the turnedover end of the bolt-cloth, the plate having both ends of the circular tightener attached the circular tightener relative to the plate, substantially as set forth.
In testimony whereof I afiix my signature in presence of two witnesses.
