IMPROVEMENT- IN FLOUR-PACKERS.

Specification forming part of Letters Patent No. 24,963, dated August 2, 1859; reissue No. 4,626,`dated N0- vember 7, 1871; extended seven years; reissue No. 6,041, dated September 1, 1874; application filed August 19, 1874.

To all A20h-om -it may concern:

Be it known that I, ASAMUEL TAGGART, of Indianapolis, in the county of Marion and State of Indiana, have invented certain ,new and useful Improvements in Flour-Packers, ot' which Vthe following is a rfull and exact description, reference being had to the accompanying drawings and to the letters of reference marked thereon.

Figure 1 represents a perspective view, showing the construction and general arrangement ot' a portable flour-packer and the combination therewith of au adjustable friction-brake, by means of which the pressure of said auger upon the flour is controlled during the operation of packing; Fig. 2, a sectional view of the clutch-wheel detached, showing, in section,

the construction and arrangement of the bearing thereof, together with the lubricating de vice and thc bearing therein for the vertical packingshaft, to which the auger or packing blades are attached. Fi represents, in section, the suspension-bearing, by which the upper end ofthe packing-shaft is connected with one end of a Walking-beam or lever, the latter being connected by its other end with the friction-brake, by which the pressure ot' the auger upon the iiour in the process of packing is controlled, and also showing the mode of lubricating the saine; and Fig. 4, a side elevation of the machine, y barrel in section and a part of the Hour-chest cut away to show 'the packing-shaft and au ger. This invention relates to what is known as the auger-packer-that is, spiral bladesA or wings, with balancing issues tixed on or near 'the lower end of a vertical rotating' shaft, by means of which the flour is packed or pressed into barrels or otherreceptacles'; and my invention in such packer consists in the construction, combination, and arrangement ofdevices, hereinafter named and described,by which the/packer is rendered compact-and portable, and which may'be constructed in the shop as an article of manufacture, and transported to and set 'up in a iiouring-mill without material alteration ofthelatter, and is designed to take the place, especially in small mills, of the cumber` some and expensive stationary packers heretofore in use.

showing the As the chief object of my invention was to. reduce the packer within the least practicable dimensions, and at the same time retain, or possibly increase, its packing capacity, my iirstefforts were directed to means by which to so control the'pressure of the auger upon the flour that the requisite quantity (one hundred and ninety-six pounds) might be readily packed into suitable barrels,y even of varying size. This I accomplished by means of a friotion-brake, combined for action With the auger in a manner that the pressure upon the onr being packed is under perfect control.

The parts incidental in carrying` out this combination Will. be described hereafter, as

showing one mode of connecting the parts so combined, by which: the pressure upon the flour as it is being packed may be controlled, as stated.

A A is the frame-work, to Which is attached all the other .parts of the packe-r. standard on the upper plate or cap of the frame, in whichthe lever or walking-beam C is pivoted for a fulcrum, and which operates the packing-shaft. D D1 is the packing-shaft,

on the lower end of Which the auger or pack- The upper end of the ingblades are fixed. packing-shaft is hung by a swivel-bearing to oiie end of the lever or walking-beam C, and the other end of said lever is connected with the friction-brake by means of the rod K, which is provided withra cogged bar at its lower end, which, matching with a cog-pinion, M, lon the shaft of the friction-drum X, forms the connection, between-the auger and the brake, by which the desired pressure of the auger upon the flour is obtained. `E is a pulley, whichmay be connected by belt with any suitable driving part of the mill machinery. Fis a bevel-wheel on the same shaft with pulley E, and which gears with` the horizontal bevel-Wheel G, the latter having va Vclutch -plate, I, in its upper' part, through which the wings of the-upper part, D1, of the packing-shaft pass, and by which thevclutchconnection is obtained, which imparts a rie-` volving motion to the auger-shaft. The ribs or wings D1 serve as levers upon the clutchplate to revolve the shaft, and these ribs fit into recesses in said clutch-plate, to allow the Bisa packing-shaft to belraised and lowered while it is also revolved,'and thus causes the substance as it falls from the reservoir or chest A2 to recede from the lat surface of the blades while being packed in the barrel. Thel lour, falling upon the auger J J as it revolves rapidly, is laid in thin layers under the pressure or force applied by the friction-brake. clutch-wheel G has its bearing centered within a boxing formed by the casting H, as shown in`Fig. 2, which also serves as au oil-cup, to keep the bearing constantly lubricated. G2 is a plate, made in halves, and bolted to the box or bearing-plate H, to secure all together, and especially the holding-flange H2 of the clutch-wheel.

It will be seen, by reference to Fig. 2, that, by means of the wheel G furnished with the clutch-plate I, and having its bearing in the oil-cup H, the Acentral part c of which is so vformed as to constitute a bearing for and support in an upright and central position the packing-shaft D D1, that the latter may havea vertical movement, so as to be lowered 4into the barrel, and automatically rise as the tlour is packed into it, the resistance to rise, and consequently the pressure ofthe au ger upon the ilour, being controlled by the friction-brake. The friction-brakeis composed of afriction drum or pulley, X, hand-wheel L, pinion M, and ratchetwheel O, all lixed on the same shaft, which is mounted in suitable bearings, and levers or brake-clamps R1 R2 and ratehet-pawll). The ratchet-wheel O and pawl P are designed to keep the packing-shaft and auger from dropping down by their own weight when the packed barrel is removed, and the hand-wheel L is designed as a convenient means of lowering the auger into the empty barrel, the pawl P being disengaged from the ratchet- Wheel O for this purpose. The brake-blocks R1 R2 are arranged,to nearly surround or embrace the friction-drum, one of these clamps,

' R1, being pivoted at D2 and having a lever, It,

extending horizontally from its upper end, so as to clamp the drumX again st the fixed jaw R2. The force with which the clamps gripe the drum is regulated by means of a weight, S, hung upon the lever R. It is found more convenient to lpack a little more than the. requisite quantity of our, so thatby taking out a little of it the right quantity Inay be more readily determined. In the operation of the machine, the weight of the iiour in the barrel is determined' approximately by the weight of vthe brake, and then weighing the lled barrel upon scales. If there be too little flour in the barrel, l move the weight toward the end of the lever; if too much, the weight is moved toward the brake, the weight being only to regulate the pressure of the auger on the flour when packing; but in this way the brake is set so as to pack in every barrel one. hundred and ninety-six (196) pounds, or a little over, rather than under, and then, in weighing on the flour-scales, the surplus is taken out of the barrel'.

The

A very important advantage results from the combination of the hand-wheel with the diction-brake and packing-shaft, in enabling the attendant, in lowering the paekingauger into the barrel,- to obtain the beneiit of the 4partial aetion'of the brake land thus prevent the too sudden descent of the shaft. The mo`- tion of the friction-drum, in lowering the auger, tends to open the jaws of thevbrake and thus relieve the friction very considerably, but the Y' brake will still bite sufficiently upon the drum to overcome the weight of the packing-shaft to a degree that will eliect and insure its safe descent to the bottom of thebarrel, and thus greatly relieve the labor of the operatorin this movement.

The top of the shaft D, as shown in Fig. 3

is constructed with an oil-cup, in which the bearing F2 rests as the shaft `D is revolved, by which arrangement a safety oil-cup is formed, insuring a good supply of oil without dan ger of greasing the packin g-shaft and m aking the friction at the point of suspension very light. The use of the oil-cup H H, with the eap G2 G2 holding the fiange H2 H2 ot' the clutch-wheel G, makes it unnecessary to have more than one bearing or journal for the clutch-wheel, and by the arrangement of two interior bearings, one, c, within the oilcup -ot' the clutch-wheel, and the other, b, at the bottom of the `flour-tube, I am enabledwto shorten the packing-shaft, dispense with the fixed bearings above the clutch-wheel, and place the whole machine in the single story of a mill without diminishing the capacity of the machine. The oil-reservoir and bearing for the clutch-wheel G is formed in a fixed plate, H, which also serves as a bearing for the packing-shaft, by having a tubular portion or sleeve, c, for that purpose. The horizontal bearing forms the oil-cup, and, being an annular chamber, forms lalso a centering-bearing for an annular flange on the clutch-wheel, and thus maintains its central position with the packing-shaft. The iiour isvfed into the feeding-tube through a spout, d.

I have shown one of the commonest forms of brakes, butv it is obvious that any desired construction of variable weighting-brake may be used, so long as the results herein described are attained.

Having described my invention, I claim- 1. A portable auger packing-machine, having a short packing-shaft and a pressure-controlling brake, and the several 'parts constructed and arranged to occupy a single tloor ot" a mill, instead of two or three stories, as heretofore, as described.
