IMPROVEMENT IN FLOUR-PACKERS.

Specification forming part of Letters Patent No. 197,533, dated November 27, 1877; application filed November 27, 1875.

To all whom it may concern:

Be it known that I, FREDERICK WOLF, a resident of the city of Cincinnati, and State of Ohio, have invented certain new and useful Improvements in Flour-Packers, of which the following is a specification:

My invention relates to that class of machines which are employed for packing fiour or other pulverized or ground materials into barrels or similar receptacles; andmy improvements are more especially applicable to the form of apparatus patented by Judson Mattison, March 9, 1858, and arefully described hereinafter, having for their objects to properly and uniformly feed the flour and regulate the movements of the platform supporting the barrel.

In the accompanying drawings, forming part of this specification, Figure 1 is a view, in perspective, of my improved packer, the platform being shown in its elevated position, and .the clutch-coupling disengaged. Fig. 2 is an axial section. through the lower part of the cylinder or trunk. Fig. 3 is a view, in perspective, of the fImnel-section, with the cylinder detached therefrom; Fig. 4, a detached perspective view. Fig. 5 is an elevation of the disengaging mechanism. Fig. 6 is a view, in perspective, of the devices employed for counterbalancing the platform; and Fig. 7 is a vertical section through the hopper and funnel.

ver, 1), situated at the rear side of the machine.

This gate or cut-off serves to regulate the quantity of flour that escapes from hopper B into funnel O, which latter is attached to the frame of the machine in the manner represented ,orinanyotherconvenientway. Coupled to the neck 0 of this funnel, by bolts d or otherwise, is a removable trunk, cylinder, or conductor, D, that conveys the flour or other pulverized material into the barrel.

By thus temporarily coupling the cylinder to the funnel-section, I am enabled to readily apply a trunk of greater or less length or diameter, according to the kind of receptacle that is to be filled, whether it be a barrel, halfbarrcl, or bag.

Occupying an axial position within the fun-'- nel G and cylinder D is a shaft, E, the lower end of which carries two separate and distinct pairs of screws or angers, F F and G G, which are respectively attached to said shaft by means of set-screws.

In applying these screws to their drivingshaft IE, it should be done in such a manner as to bring the open spaces between the upper pairs F F, directly above the solid portions of thelower screws GG,as this arrangement will completely obstruct the cylinder, and efiectually prevent any escape of flour from the cylinder when its lower end is exposed by the removal of the filled barrel.

Attached to shaftE is one ormore radial arms, 0, which act to agitate the flour within funnel O, and thereby prevent it becoming clogged or choked up.

H is a clutch-coupling, which is capable of being thrown either in or outof gear with bevel-wheel h, by means" of lever I, whose office will presently appear. The wheel h meshes with another bevel-wheel, J, secured to a horizontal shaft, j, that is rotated by a band passing around the pulley j.

K represents the flour-barrel, which is supported upon a platform, L, attached to a cage, M, whose cross-beam m is connected to the winding-drum N by means of two or more chains, ropes, or other flexible connections, 0 O. The lower ends of these connections take hold of ring-bolts 0, which traverse the beam m, and

riphery of which is passed a strap, 8, that is connected to a lever, T, upon which rides a shiftable weight, t. V

The object of this strap and weight is to produce a greater or less degree of friction upon the wheel S, and thereby act as a brake or tension device to regulate'the rotation of drum N.

The clutch-lever I, previously alluded to, has attached to its outer end a rope, U, which, after passing over two rollers, u u, carries a weight, V, that is heavy enough to disengage the coupling H as soon as said lever is 1mlocked by the descending platform.

This unlocking of the lever is accomplished in the following manner: By referring to Fig. 1, it will be noticed that a connecting-rod, W, extends from said lever to a hand-lever, X, the latter being pivoted at a: to the stanchion a. Secured to this hand-lever is a hookcatch, Y, that is adapted to engage under a strap, 9 which is attached to the main frame of the machine. y is a guard that prevents the hook Y becoming accidentally disengaged from the stop. Z is an adjustable tappet that is secured at any suitable elevation on the cage M of the platform.

The operation of my packer is as follows: An appropriate cylinder, D, is first applied to the neck 0 of funnelO; the barrel K is then properly located upon platform L, and the latter elevated by rotating the winding-drum N with hand-wheel 1?. As soon as the platform has been elevated far enough, the cage M strikes against the fixed cushions z, and thereby arrests the further movement of the devices L M. The weight 15 is now adjusted upon lever T, the gate B opened, and the catch engaged under stop y. The flour at once flows down hopper B into funnel O, and thence into conductor D, as indicated by arrows in t Fig. 7.

The engagement of catch Y with stop y throws the coupling H in gear, and conse quently the shaft E is driven by shaft j. This rotation of axial shaft E causes a corresponding movement of the'two pairs of attached screws F F and G G, which act to pack the flour evenly in the barrel. This continued and forcible packing of the flour causes a corresponding descent of the platform, and as soon as the latter has been carried down far enough to insure the complete filling of the barrel the tappet Z strikes against the catch Y, and at once 'disengages it from the stop y. The weight V instantly elevates the outer one substituted in its place, after which the above-described operations are again repeated, with the exception of the adjustment of the braking mechanism S s T t, which requires no attention after it has once been properly regulated.

I have described my apparatus as a flourpacker, that being the use to which it will genera-11y be put; but Ido not propose to limit the" machine to this purpose alone, as it is evident it may be employed for packing calcined and land-plaster cement of any kind, &c.

I am aware that elastic couplings have been heretofore used, but I am not aware that they have been combined with apower-driven drum the sudden movement of which, when thrown in gear,'renders it very desirable to provide means for overcoming the abrupt action.

' What Iclaimas new, and desire to secure by Letters Patent, is-

1. The combination of vthe detachable trunk D, the hopper-gate B, the intermediate funnel O, expanding toward the top and communicating with the trunk at its contracted lower end 0, and the shaft E, provided with arms 6, arranged in the funnel above the lower end thereof, all as set forth.

2. The combination of the sliding platform L M, the screw-shaft E, driving-pinion h, clutch H, and connecting mechanism whereby the said clutch is operated on the movement of the platform, substantially as set forth.

3. The combination of the sliding platform, winding-drum N, and connecting chains or bands secured through the medium of a yielding or spring coupling to the platform,.as set forth. 7

4:. The combination of the sliding platform of a flour-packer, a balance-weight and cord, and a drum of gradually-increasing diameter, whereby the leverage exerted by the weight increases in proportion to the increased weight upon the platform, as set forth.

FREDERICK WOLF.
