WILLIAM BAsuoii, or JOHNSON Grrr-TENNESSEE.-

IMPRovnn :decameron PACKING FLoUa, am.

The Schedule'refen'ed to in these vLetters Patent: and making part cf the same vl'o all whom it mag/concern.-` y Y Be it known that I', WILLIAM BAsHoR, of Jobnson City, in the county of Garter and in the State of Tennessee, have invented a new and'usefnl Improvement in Flour-Packers; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, snnicient to enable any one skilled inthe art to make, construct, and use the same, reference being had to the accompanying drawing making part of this specification, in whiclndrawinginafter be described;

Like letters of' reference indicate Acorresponding parts. Y

A,in the drawing, may represent the .base of the flour-packer.

BeB, upright standards.

O O, cross-beams..

D D, lSliding-standards vor connections secured to the top P, and carrying the case F.v

G is a movable vertical shaft, carrying a bandwheel, H, and the conical-shaped rollers K K and K' K';

A is the base or foundation ofthe'our-packer, upon -the outer ends of which are firmly secnred,in a suit-- to be mentioned.

G is the vertical revolving shaft, provided at its lower end with suitable metallicjournals c ccc, bearing the conical-shaped rollers K K K' K', i-n such a'manner that the said rollers may adjust themselves while the shaft lis revolving, the rollers acting upon the flour or other material inthe sacks', bags, or other packages.

The rollers K K are made preferably double the size or of a much greater diameter than the rollers K K, in order, that the rollers K K; will perform lat least two revolutions'to one revolution of the rollers K K.

The object of employing the large and small vconical rollers-is that, asthe flour is thrown into a case, or conveyed intcfthe same from a hopper or other suitable device, the shaft revolving and the rollers coming in contactwith the lour,the flour is snugly and closely packed infthe center, and at the same time forced outward toward the yinterior surface of the sacks by the small rollers, when the rollers K K,per forming their function, press down vreliably all onr or other material coming in contact'with them.v

The lower part, or about. one-halof theshaft G is made of a circularforruation, while'rthe upper portion, except -its extrme end, is made square or aug.nlar. i y A The ltop part of theshaft Gr is made circular, and is provided with a netallie washer, hung either loosely or made fast with `the'shaft, yas maybe desired..

' H is a band-wheel, hung looselyfupon and isthe means whereby .the .vertical'shaft G is revolved, while theilour or other material is being packed.

This band-wheel 4H is` formed on provided with projecting armsorangeshla and may embrace the vertical shaftxGgtheentire `4distance between the two cross-beams 0.0.'

The opening-ork space -inf the center of the `bandl wheel, and its arms or vlanges','is made of a form. corresponding tothe square or angular portion ofthe shaft G, so that, when the power is applied 'to the 'band-wheel, by meansof a belt attached Ato a suitable pulley, the shaft `will revolve with it while packing the nour or other substance, but when the shaft is raised, until the circular portion of the vertical shaft enters the opening in the band-wheel and its arms or flanges, the latter will revolve while the shaft remains stationary.

This is an important function', as it not only allows the ready .attachment of an empty sack, bag, or other package, when the one on the case is packed as full as desired, but also saves power and machinery, there being no resistance offered by the vertical shaft during the-intervals of placing and replacing. the sacks, bags, or other packages upon the case. M M are arms, arranged transverse between thel cross-beams C C, and are'provided with circular openings O, seen in dotted lines, of a diameter greater than that of the arms or flanges 7:A h of the bandwheel,in such a manner that the said arms or flanges of the band-wheel are embraced and supported by the circular openings of the arms O C, at the same time not'interfering with the free revolution of the bandwheel. ,l

' These arms M 'M are provided near their outer ends with openings a c, for a purpose vhereinafter to be mentioned.

D D are upright standards or connections sliding freely up and down in the openings a a of the cross- 'beam G .G and the openings e c, in the transverse arms M. M. l

F is a case, made either of metal or wood, as may be desired, and upon which case the bag or sack to be packed is placed.

The upright connections D D arc secured to the A`inner surface of the case F by. means of bolts or screws,

and extending upward pass through the openings a a and ce, and are then either `secured firmly to the top `plate I or pass tln'ough-openings g g, formed in said when placed upon thercase, and its e'nds fasteued'to-- gether by means of suitable hooks or catches.

r.ihe several parts'cemposing this packer are made either of cast, wrought, or other suitable metal, although wood can bc used in its construction.

I am aware that conical rollers of equal size have ,long been known and used in machines for packing flour and like materials, but such I do not claim.

'I am aware, too, that broad band-wheels or drums have been used for rot-ating the shaft carrying packing-rollers of equal size, but they have been uniformly keyed fast to the shaft, consequently t-he rotation of the one could not be stopped without stopping the i rotation of the other.

I am also aware that cog-wheels, provided and combined with sliding-sockets, clutch-pins, friction-rollers, and various other clutching devices for stopping the rotation of the shaft carrying the packing rollers when raised to a certain height, without discontinuing the rotation of said operating wheels, have been known and used, but these have proved to be` too complicated and expensive `in construction and uncertain in action, and I disclaim all such.

I am not aware, however, that an arrangement for accomplishing the desirable object above stated so cheap and simple in construction', and certain. in function as mine, has ever-before been devised.

Having thus described my invention,

WVhatI claim as new, and desire to secure by Letters Patent, is

1. The combination and arrangement in a machine for packing flour and like material, ot' the conical dif-' ferential rollers K K', and revolving shaft G, substantially as described, and for the purpose set forth.

2. The band-wheel H, provided with the shoulders h, and an angular opening through its center, in combination with the vertically sliding shaft G and arms M, when said parts` are 'constructed and arranged to operate substantially as described, in 4the manner and for the purpose specified and shown.

3'. The machine for packing iour and like material herein shown, consisting ofthe frame A B, crossbeams C, sliding standards D, arms M, wheel H, shaft G, case F, and plate l), constructed, combined, and arranged for operation, snbstantiallyas described.

To the abovel have signed my name this 24th'dzty of May, 1870. i
