Letters Patent No. 110,155, dated December 13, 1870.

IMPROVEMENT IN VFLOUR-PACKERS.

The Schedule referred to in-these Letters Patent and making-part of the same.

To `whom it may concern:

Be it known that I, ADDISON H. NoRDYKn, of the city of Richmond, Va-yne county, Indiana, have invented certain new and useful Improvements in Flour-Packers; and I do hereby declare thefollowing to be a full, clear, and exact description of the same, reference being had to the drawings which accompany this specication, vforming a part of the same, and to the let-ters of reference thereon, in which- Figure l represents a rontelevation of my improved machine, and

Figure 2 represents a side elevation of the same.

Like letters refer tov like parts.

The nature of my invention consists in the employnient of a supplemental tube or case, in which the` ilour is packed or compressed previous to being deposited or discharged into the-'barrel or 'sack used to contain the same.

To enable those skilled in'the art to construct and operate my improved Hour-packer, I will proceed to describethe' same.

In Figure l, AAA A represent an upright frame, having a cross-piece, A', secured across the top.

Within the upright -side pieces of said frame, and

occupying the upper portion thereof', is a cylinder or hollow case, )Tn-secured to vthe framing at the upper end rigidly in any suitable manuel'.

.A perpendicular shaft, F, is placed iu the center of the'yliuder E, the lower end of which is furnished with spiral anges, permanently affixed, while to .the upper portion of the same, andabove the top of the case E, a bevelpinion, L, is attached by keys o o, which are constructed to slide in grooves or splines which traverse the opposite sides of that portion of the shaft F vertically, and which communicate motion to said shaft by means of the bevel pinion K' on the shaft J operated by the driving-pulley I;

f The lower end of the bevel-pinion L, which has its bea-ring in the cross-piece A', is provided with an an- .nular recess, N, into which are fitted the forked jaws of the lever M, pivoted at a to the cross-piece A', and which is used to elevate or depress the bevel-pinion L into or ont of gear with the corresponding bevel-pinion K, by which it is operated, the motion of which is shown in red dotted lines.

Secured to the top of the frame, in a proper manner, is a yoke-frame, It It, the inner surface of which is in the form of a guide, upon which a cross-head, H,

has a vertical motion, being raised by the upward mo-v tion of the shaft F, and lowered by the4 operation 0f the weight O, by means of the cord or chain j, which passes over the pulleys I), c, and d, and is attached to the cross-head Hat k, tig. 2.

The inner surfaces of the upright postsA A are grooved to receive a sliding frame, having a platform,l

Y O, and, on one side, curved guards B B B, intended as rests or supports for the barrel or sack, which may.

be placed upon the platforinO to be filled.

lraversing the bottom `of the platform O, and attached thereto, is a catch-bar, provided with catches D D', which rest in keepers l and 2, when the platform is raised.

' This catch-bar is so arranged as to slide in its bearingsfand may be released by the operation of the jointed arm V of the rocking-lever U, and is restored to its place by the operation of aspriug or other suitable device.

Attached to the platform O is a belt or strap, y provided with holes, said belt passing over thepulley Z, and attached to which is a Weight or connterpoise, for the purpose of raising the platform C when ready for use.

. The rockingllever U, iig. 2, is pivoted to the upright A, and is provided with a sliding weight, u, and the lower portion is curved to correspond with the periphery of the pulley P, upon whichv it acts as a brake, and, iis the brake is applied, the downward motion of the handle of the lever operates the jointed arm V, which serves to disen gage the catch-bar and its catches D D' from the keepers l and. 2, when the weight of the package upon the platform G causes it to descend.

In its descent the strap or belt y raises the weight Y over the pulley Z, Whiclris secured upon the ceutral portion of the shaft t'.

Upon the end of the kshaft t is a scroll-pulley, W, which is intended to make a little less than a revolution in the entire traverse of the platform O.

The lever X,pivoted to the framing, is provided with a rubber block, x, at the end opposite its handle, which rubber block has more or less pressure or friction given to it by means of a spring, on, graduated by a wedge, n.

At the beginning ofthe descent of the platform the rubber block :o is opposite the smallest diameter of the lscroll-pulley W, and traverses the circumference to the point of its greatest diameter, lthus increasing the friction automatically', until it reaches its destination,

Aas 'shown in the drawings,` Figure 2.

The connecting-rod Z'is secured, at its lower end, to the rockingdever U, and at the upper end to the lever M, and produces the-simultaneous motion of these two levers.`

rI he perpendicular rod Q passes through ears f f, fixed to the framing, and is provided with one or more weights at its lower end, together with acord or chain, j', which cord or chain passes over the pulley I in a contrary direction to that of the cord or chain j.

' The motion of the pulley P winds up the cordj', and, at the same time, raises the rod Q until the adjustable collar e with which said rod is provided comes in contact with the trigger T, which releases the lever my, and allows the bevel-pinion L to drop out of gea-r,

and stops the motion of the shaft F.

rlhis movement elevates the end of the lever M, to which the handle is attached, which, in turn, elevates the handleof therocking-lever'U, relieving the friction upon the pulley P, and, by the same motion, operates the jointed arm V, which in turn releases the catch-bar of the platf'orm O, allowing that to descend in the manner already described.

S, g. 2, is a hopper, through which the liour passes into the supplemental packing-cylinder, suitably sccu'red to the top of the framing.

The operation of the packer is briefly as follows The barrel, sack, or other article to be lled is placed upon the platform C, and raised up outside of andin-y closing the supplemental packing-cylinder E, when the catch-bar drops into the keepers at each end, where it remains during the process of packing each parcel. The operator throws the bevel-pinions in gear by means of the lever M, which puts the shaft F and the packing-flanges G in operation. VAs the packing-cylinderbeconles lled the shaft F rises through the center of the bevel-pinion, carrying the cross-head H with its cord or chain 7' andthe weight O, which creates a pressure upon the sha-ft F, which is modified or increased by the pressure given upon' the periphery of the'pulley P by the weighted a-rm of the rocking-lever U, as well as by increasing' or diminishing the number or size of the weights attached to the lower end of the rod Q, thus giving more or less density to the flour in process of packingin the packing-tube E.

The adjustable collar e on the rod Q is set at such a point as will stop operations when the desired anion nt isvreceived into the packing case as the said rod is elevated in the manner just described. \Vhen the triggerjl is operated by the collision with the cllar e the bevel-pinion L recedes from gear operating the lever 'M, the connecting-rod l, the rocking-lever U, the jointed arm V,releasing the'.catchbar of the plat- .form 0,7when the said platform instantly begins its descent, which is governed and controlled by the lever a: and'its connections operating upon the scroll-pulley, as herein fully described.

It will be seen that, i'n the process of packing, the the supplemental packing-cylinder' E receives allA the pressure, and that no strain or pressure is exerted upon Athe barrel, bag, or sackto be packed, and that the our is sulistantially delivered into its appropriate receptacle after having been packed or compressed to the required degree.

It-willalso be seen that, as the platform O descends from the point at which the packing is completed, the shaft F, with its spiral packing anges G, follows simultaneonsly, forcing the contents of the cylinder-E into the barrel, sack, or bag. i

Having thus fully described my said invention,

Y What I claim as my invention, and desire to secure by Letters Patent, is

l. The method herein described of packing our by holding the platform which sustains the package stationary while the lour is packed in a supplemental cylinder within the package, substantially as s'et forth.

2. The combination ot' the stationary cylinder E lwith the platforrnO, sustained during the packing operation by the catch-bar D D and keepers l and 2, arranged to operate substantially as set forth.

3. The platform C, constructed and arranged as described, in con'ibinationwith the strap y and weight Y, used in'connection with the flanges G G and supplemental packing-cylinder E, operating in the inanner and for the purposes herein set forth and described.

v 4. ThehereinQdescribed mechanism for releasing the platform G from its keepers simultaneously with throwing the wheel L out of gear to stop the packing operation, consisting of the cross-head H, cord j, pulley P, weighted cord jO, tappet-rod Q e,trigge1"l, lever M, connecting-rod l, brake U, wedge V, and catchf bar D D', all arranged relatively to one another as set forth.

5. The ycombination of the packing-shaft -F G, crosshead H, cord i, pulley P, weighted brake U u, and weighted cord jf O, 'substantially as and for the purpose set forth.

6. The shaft i, the drum Z, andthe scroll-pulley lV, in combination with the lever X, and its spring m and wedge n, when used as and for the purposes set forth.
