I Improved Flour` Bolt.

PATENT OFFICE.
WILLIAM BASHOR, OF JOHNSON CITY, TENNESSEE.
IMPROVEMENT IN FLOUR-BOLTS.
Specification forming part of Letters Patent No. 118,508, dated August 29, 187,1.
To all whom it may concern:
y Be it known that I, WILLIAM BAsIIoR, of Johnson.Oity, in the county of Garter and State of Tennessee, have invented'a new and useful Improvement in Expanding the Cloth in Flour- Bolts; and I do hereby declare that the following is a full, clear, and exact description thereof, sufficient to enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this speciiication.
The nature of my invention relates to an improved method of expanding the cloth in iourbolts, which I accomplish by sets of arms radiating from a central shaft pivoted at their outer ends to longitudinal bars or ribs, and their inner ends to the circumference of collars tted to and sliding upon said central shaft. By means of these said sliding collars with their accompanying pivoted radiating arms, which constitute the leading feature of my invention, actuated by certain other suitable devices, I am enabled easily and quickly to expand or contract the boltingcloth, as the necessity of the case may require.
To enable others skilled in the art to which my invention relates to understand the manner of making and using the same, I will proceed to describe its .construction and operation, reference being had to the accompanying drawing forming part of this specification, in which- Figure l is a side view of a bolting-reel with the cloth removed, showing the several parts of my invention. Figs. 2 and 3 are end views of the same. Fig. 4 is a detached view.
A represents an annular wooden or metallic shaft having formed on it or provided at its ends with suitable bearings. Surrounding and sliding on this shaft are wooden or metallic collars c a, on the circumference of which, at equal distances, are formed slots or lugs b b. The inner ends of the radiating arms cl el fit within these slots and are pivoted to the collar, which admits of a vibrating movement in the direction of the shaft A. At their outer ends they are pivoted in any suitable manner to the longitudinal bars or ribs cc ofthe reel, which form a support for the boltingcloth.
It will be observed that the arms d d are made to set at an incline or diagonally to the shaft A; but by sliding the collars in the proper direction, causing them to approach a perpendicular with reference to the shaft A, they force out the ribs c c of the bolting-reel and thereby expand the bolting-cloth.
I will now proceed to describe the devices by which this movement of the collar is produced. The shaft A is formed hollow its full length or for a suitable distance, and is also centrally slitted for the same distance. Within this slit or openingf slides the flat metallic plates g g", their centers being expanded into a ring within which screw-threads are cut. The plate g has a lefthand cut, while the plate .g has a right-hand cut. The outer ends of the plates g and g pass through and are secured to the collars at a al. A crankshaft, h, rests in suitable bearings within the hollow shaft A. Its inner half has a right-hand screw-thread cut upon it, and its outer half a lefthand thread, to correspond with the screw-threads in the plates g g. The shaft is provided with the crank t', by which it is rotated.
It will be observed that by giving the shaft h a right-hand turn, owing to the opposite screwthreads upon its surface, will cause the collars c a bearing the radiating arms to approach each other and stand perpendicularly to the central shaft A, and thus force equally outward the bars or ribs c c of the bolting-reel, thus stretching uniformly the bolting-cloth, and, by a reverse motion, to recede and slacken said cloth.
NN are rods arranged opposite to each other on the circumference of the central shaft A, having formed upon their ends eyes or hooks m m, by which means they are secured upon opposite sides of the collars a1 a2 c3, and by which said collars are connected together and their joint and uniform movement in either direction upon the shaft A is produced. It is thus evident that if the sliding rings are made to approach each other by turning the crank z', the pivoted arms radiating om the collars a2 a3 correspond in their movement to the arms al, and as all correspondingly approach the perpendicular they force the bars or ribs c c of the reel outwardly, and thereby secure the equal and uniform expansion of the bolting-cloth. Upon the ends of the bars or ribs constituting the reel are the heads D D', formed with central openings, through which the journal of the shaft A extends. These heads are formed or provided with guide-grooves 0 o, within which slide freely the metal or wooden plates p p, secured within the slots 1' r of the bars or ribs c c; or the said bars may be formed with the plates r r, if it be desired. Thus it will be seen that the attachment of the bars of the reel upon the reel-heads are adjustable; hence they do not interfere with the free movement outwardly or inwardly of the said reel-bars for the purpose of expanding or contracting the bolting-cloth attached thereto. The head D of the reel is provided with a hollow conical guard, E, which is secured within the opening of said head, and is designed to prevent the lour or bran-specks ilying out of the bolt. G G are braces for connecting and bracing the central shaft and reel-head together.
The bolting-cloth is constructed the same as that usually used, With the exception that each end is overlapped and surrounds a flexible wire, said wire with the cloth surrounding it being interposed between the heads D D and the disk or strips H by means of screws or fastenings passing through the latter into the head of the reel.
A boltin g-reel provided with my improvements dispenses with the necessity, expense, and delay of removing the bolting-cloth for the purpose of tightening the same, as is now the ordinary way.
It will also be noticed that the novel means provided for contracting the reel and cloth enables me to cause the whole bulk to occupy a very small space in comparison to flour-bolts now in use, which is a very great advantage, especially in transportation.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. The arrangement of the loose collars a a1 a2, rods N N, shaft A with hollowed end section, pivoted arms d d, bars o c, plates g g, and screw h, all constructed and operating substantially as set forth for the purpose specified.
2. The heads D D provided with guide-grooves o o, in combination with the plates p of the reelbars or ribs c c, substantially as and for the purpose set forth.
3. The shaft A with hollowed end section, gear g y', screw h, loose wings a al a2, and connectingrods N N, in combination with the pivoted arms dal, reel-bars cc, and guide-grooves o o of the reelheads, for the purpose of expanding the boltingcloth, substantially as described.
To the above I have signed my name this 24th day of June, 1871.
