SPECIFICATION forming part of Letters Patent No. 398,999, dated March 5, 1889.

Application filed March 3, 1888. Serial No. 266,018. No model.)

To ((7/1 "who/1r it may cancer/z:

Be it known that I, Hanan A. LARNARD, a bevel-gear,

of Moline, in the county of Rock Island and l State of Illinois, have invented certain new and useful Improvements in FlouePackers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawi lugs, and to the letters of reference marked thereon, which form, part of this specification. in which- I Figure 1 is a front elevation of my improved flour-packer. Fig. is a side elevation of the same. I3 is a side elevation showing a modification. Fig. l is avie'wol' the gearingframe detached. Figs. 5 and 6 are details.

This invention relates to improvements in flour-packers; and its objects are to provide improved mechanisms for starting the packer and for automatically stopping the same, and, further, to improve the supports of the gear iug of the packer. These objects I attain by the present invention, which consists in the novel construction and arrangement of parts hereinafter d escribed, illustrated in the drawings, and particularly specified in the claims hereto appended.

Referring to the drawings by letter, A designates the main frame of the packer, consisting of two vertical uprights, a a, suitably connected at top and bottom, which may be provided with any suitable guides for a vertically-reeiproeating platform, XV, hereinafter referred to. At the top of frame A is mounted a rectangular frame, B, made of cast metal. This frame has bearings 19 I) cast integral on its upper and lower rails and forming half of the journal-boxes of the vertical anger or packer shaft 0, which is confined in bearings 12 b by half-boxes c c, bolted to frame B, as shown.

At one end of frame B is formed an offset arch, D, provided with a bearing, (1, which stands at right angles to bearings 19 b and corresponds with a similar bearing, E, formed on the adjoining end rail of frame B, as shown, the latter bearing, E, however, being lengthened, as shown, to properly align and support a short shaft, F, which is retained'in bearing E by a cap, 0, bolted to frame B, as shown. The shaft F, it will be seen, stands at right angles to shaft 0, and bears on its inner end meshing with gear on shaft 0. On the outer end of shaft F is mounted the cup wheel of a friction-clutch, G, hereinafter referred to. Gear f and wheel 9 are set on shaft F,so that it is kept from any longitudinal play in hearing E.

H designates a shaft, one end of which is supported and journaled in bearing (7, being retained therein by a cap, 72., as shown. Shaft H lies in line with shaft F, and bears on its inner end, within. offset D, the iuorable disk g of the friction-clutch G, as shown, which is properly mounted on shaft H, so that it can be engaged with cup-wheel g and impart motion to shaft F. The other end of shaft H may be journaled in any suitable support in the building where the packer is mounted, and motion is imparted to said shaft by any proper power. The shafts F and H constitute a sectional counter-shaft by which the packer is operated.

I indicates a movable arch. bolted to the upper rail of frame B through openings i-i therein, so that the arch will stand directly over the upper end of shaft 0.

J designates an oil-cup fitted on the upper end of shaft C, andj is a set journal screw mounted in arch I and entering cup J, so that the shaft C will be kept from rising in its bearings on frame B. Cup J can be filled with oil to prevent wear of the parts J and j.

i 1" are openings in the lower rail of frame B, corresponding in position to the openings 2' 2', so that, if desired, frame B can be re versed and shafts G and F be on the lefthand side of the machine.

K K are similar arms or studs projecting rearwardly from the arch D at equal distances from bearing d. Stud K in this instance forms the pivotal support for a lever, L, the bifurcated upper end of which loosely engages the hub of the movable disk g of clutch G, as usual, so that by oscillating lever L the parts 9 and g may be engaged or disengaged. hen the frame B is reversed, lever L is mounted on stud K. The lower end of lever L is pivotally connected to one end of toggle -1ever M, the other arm of which is pivoted to a proper keeper on the main frame A, and this toggle-lever M is pivotally engaged at its joint with a depending rod, N, by which the toggle-lever is opened or extended.

on designates a coiled spring connected with the upper end of rod N and to a point on the frame 13, and serving to retract the rod after it has been depressed, and there by retract the toggle-lever. It will be observed that when the toggle-lever is extended the lever I, is shifted so as to throw the parts of the friction-clutch into engagement and keep them so until the lever is released and retracted, so that by depressing or elevating rod N the packer will be set in operation or stopped. The rod N extends downward nearly to the base of the machine and is attached to an angular dog, 0, playing vertically through a keeper, I, secured to the main frame. \Vhen rod L is depressed, the dog 0 is engaged byits tooth with the side of keeper P, and the dog has an inwardly-projecting bent arm, 0, which is adapted to be struck by a lug, '1 011 the platform \V and knocked outward, disengaging the keeper -P and releasing rod L. The rod N is connected with a short hand-lever, Z, pivoted to the upright a above keeper P, by which the rod can be depressed when desired, or after it has been released by the platform.

The platform WV, which is adapted to support a barrel or sack while being filled, is operated by means of a chain, Q, which passes under friction-pulleys on the top rail, 10, of the platform-support, and is attached to grooved cone-drums q g on a horizontal shaft, R, suitably journaled on the main frame at the rear thereof and extending outward on the side be low shaft H, and receiving motion from a pulley, s, on the latter shaft by a belt, S, and a pulley, r, on shaft R, as shown. Belt S is made very slack, however, so that it has to be tightened in order to operate shaft B. This is accomplished by means of a tightener, T, composed of a bifurcated angular frame mounted onshaft R and embracing pulley '7', and carrying in its upper end a friction-pulley, t, as shown. The lower end of frame T is pivot- .ally connected with the upper end of a stiff push-rod, U, which is operated by a treadle, u,

secured to the floor at the side of frame A, as shown, in convenient position to be operated by foot. The pulley-t stands within belt S,

which is preferably crossed and bears against theinner face thereof, as shown.

The belt S is used solely to cause the lifting of platform IV, and its descent is by gravity, regulated, however, by means of a frictionwheel, V, on shaft R, surrounded byafrictionband, 1:, one end of which is fixed to the main frame, and the other end is connected to an oscillating pivoted scale-beam lever X, which ported on frame A above platform \V and surrounding shaft 0, which latter is provided within the cylinder with a worm or worm-fingers, which force the material down in said tube. The upper end of cylinder Z is provided with an enlarged receiving mouth or funnel, a, into which the material is fed.

WVhile the rod N can be readily depressed by hand, as described, yet, in order to expedite the working of the packer, I employ another means for depressing the rod from treadlear. To do this a chain, L, is attached to rod N, above the dog O,'and passed over bracketpiccc M, attached to one upright a, so as to keep the chain from interfering with the dog and cause the chain when depressed to draw rod N inward, and thereby cause the automatic engagement of dog 0 with its keeper. The outer end of the'chain is attached to the treadle u, as shown.

In operation a barrel or sack to be filled is placed upon platform IV. Treadle a is depressed by the foot, simultaneously causing the tightening of belt S and the depression of rod N. Belt S causes shaft R, to rotate, winding chain'Q and lifting platform IV, with the barrel or sack, into which cylinder Z enters and delivers the material. The depression of rod N engages dog 0, causing the closing of parts 9 and g of clutch G, so that shaft C is rotated and begins to forcibly feed the flour through cylinder Z. As soon as platform is sufiiciently elevated, the treadle is released, stopping the rotation of shaft R and applying the'brake thereto. The weight on the brake-lever is so adjusted as to overcome the-gravity of the platform and require a certain downward degree of pressure to be expended upon the platform to lower it. pressure is imparted by the worm on shaft 0 as the material is packed, so that the barrel is filled properly. The cone-drums on which chain Q is wound are so graduated as to diminish the leverage of the chain on shaft R as the platform descends, and thereby compensate for the weight of the material in the barrel. hen the platform descends, the lug.

yis so arranged as to strike the dog 0 and cause it to disengage the keeper, and the parts acting as already described cause the disengagement of the parts g and g of clutch G from shaft F and the stoppage of shaft 0, and consequently of the packing operation.

Having described my invention, what I Y claim is 1. In a packer, a metal frame having bearings cast integral with it for the support of the auger and driving shafts, and a detachable arch, constructed substantially as described, attached to said frame and adapted.
