COMPRESSOR FOR COMPRESSING BEAN AND OTHER SUBSTANOES INTO PACKAGES.

SPECIFICATION forming part of Letters Patent No. 291,683, dated January 8, 1884.

. l Application filed June 5, 1883. (No model.)

ofaZZ whom it mag/concern: Be it known that I, GENRY A. CHAPMAN, of Strawberry Point, in the countyof Clayton andState of Iowa, have invented certain new 5 and'useful Improvements in Compressors for Gompressing' Bran and other Substances into Packages, of which the following is a full, clear, and exact description. i y

This invention has more especially for its Io object the compressing oi' bran and otherlight `substances into packages which may either u be square, cylindrical, or other desired shape in their transverse section, and may be niade shaft is fitted to slide longitudinally in its bearings b Z, and carries or has connected with it a frame, e, which is free to slide with the 5 shaft, and within which and fast on the shaft, so as to rotate with it, are inner and outer l large and small bevelgears, E E and F F. y The longitudinal movement of the shaft D and l frame e, carrying the gears E E and F F 6o along with it, to the right or to the left, as required, is controlled by a lever, f, connected with an arin from the frame c. u is an upright shaft, fitted to rotate and capable of sliding up and down within bear- 6 ings g g, attached to the main frame. Fast on is shaft is a combined spur and bevel gear, I-I EI; or it may be separate gears. The spur gear or portion II gears with a horizontal spur-gear, I, arranged to workin between the 7o upper cross-ties, (l C, and through which, as a nut, a screw-threaded pistoirrod, J', works, and the bevel gear or portion II gears with either ol" the wheels E la" or F lil/,accordingly as said wheels'arc slid to the right or to the left, and the gear I-I l-I is raised or lowered for the purpose. Said gear I-I H may be made to drop or lower ofits own weight onsuitabl. lowering a step bearingarin, 71 on which the shaft G rests, and which is connected with an 8o l up-and-down slide, K, on one of the uprights A. rlhis slide is lowered. or raised as required to adjust the bevel-@ear I-I relatively to the gears E E and F F by means of a bellcranklever, L. The piston-rodJ has asquare- 85 shaped piston, J', on its lower end, arranged to work within and up out of a correspondinglyshaped iilling-tube, M, which may be of l l thin metal, and which is capable of being adjusted up and down by a windlass, N, and 9o ropes or chains 13 i, attached at their one end to the windlass, (which may be controlled by pawl and ratchet,) and, after passing around sheaves s, are made fast at their opposite end to a crossslide, O, that carries the filling-tube, and that is guided by and arranged to slide up and down within the uprightsAA. When the piston J'l is within the :filling-tube or filler lM, it and its rod are of course prevented from turning as the wheel I is rotated to raise or roo lower the piston; and to prevent the piston I5 Will here be'described as being sacks of square or right-angled shape, with bottoms to corre spend, and which it is my intention to make the subject of a separate application for Letters Ifatent. 2o The invention, by way of illustration, will also here be described as used for the compression of branV into such packages; and it consists in certain novel constructions and combinations ofpaits in acon1pressor, and in 2 5 a method of filling and closing the package, i whereby great simplicity and eiiiciency are obtained and the packages may be sealed un der aheavy pressure, which gives great density to the-mass. f'

l 3o Reference is .to be had to the accompanying `corresponding parts in all the figures.,

` igure l is a front view of a compressor 3 5 constructed in accordance with inyinvention, and as in the act of compressing bran into a sack or package of square shape in its transverse section. Fig. 2 is a vertical section of the same on the line x x in Fig. 1; and Fig. 3 4o horizontal section, in part, on thelineyj/in ig. l. A A are the sides or uprights of the frame of the compressor; B, its base, and C C u1 e per cross-ties, connecting the uprights A A. 45 Saidframa however, may be otherwise suitt ably constructed.

is the main 0r operating shaft, arranged to occupy a horizontal position on erin bearings b b, projecting outward from and in front 5o of the :main iraine, which shaft may be rotated by hand applied to a crank, c, or by any suitable motor powerapplicd toa pulley, d; This tion of the rod is made square,

' of which is of a capacity to fit snugly over suitable material or tached sack,

the lower portion of the filler M, and which has a square top and bottom, may be made of sack-cloth, ducking, burlap-cloth, or other materials.

T is a hinged or opening and closing clamp, arranged externally of the sack 'when on the filler, and of about the same depth as the sack, to hold the sack in position and to support or stiffen the filler against the pressure exerted within it by the compression ofthe bran.

In the operation of the compressor the filler or tube M is drawn up to its top or extreme upward limit by the windlass N, and the clamp T, if in place on it, removed. The sack S is then drawn up over the lower end portion of the filling-tube M, so that the bottom of the sack comes in contact with the lower end of said tube, after which the tube, with the atis let down onto the base B of the compressor. The clamp T is then applied around the sack and locked. The bran to be packed is now charged within the tube M from its top, which may be done by a spout, and which is continue( until the filler M is full, or sufficiently s'o to l the sack after compression. Then the sack cover or top S', which is squarc'and somewhat larger than the filler, is placed upon the loose bran in the filler, and the lever f is moved to the left and engaged with au outer lleft-hand side locking-pin, a. The lever L is also moved to the left until the bevel-gear H engages with the large bevelwheel E. Motion then being communicated to the shaft D, the wheel I will be rotated to work down the piston J into the iilling-tube M for a distance of about one-fourth the depth of said tube, more or less. The lever f is then adjusted onto a second locking-pin, c2, to slide the frame e and its inclosed gearing somewhat to the right, and the bevel-gear I'I' is raised into mesh 'with the smaller bevel-wheel F. This will cause the piston J' tobe carried down slower and'with greater power as the resistv ance increases, land is continued unt-il the piston J reaches the top of the body of the sack or to a level with the top of the clamp T. The gears are then `adjusted so as to stop the motion of the' piston, and the filling-tube M is lifted by the windlass N out of the sack, and the clamp T is' opened and removed. This leaves the sack-body with the bran compressed within it and under heavy pressure, ready for the top S to be sewed on, after which the leverf is adjusted onto the locking-pin a3, and

It, suitably placed for the lever L suitably moved to put the bevel-gear l-l' in mesh with the reversing small wheel F', to back up the piston a little when the sack is removed. Another sack-body is then drawn onto or over the lower end of the filling-tube, and said tube is let down onto the floor or base B again and the clamp T applied and seeured,'after which the lever f is adjusted into lock with the pin a* and the lever L adj usted to bring the bevel-gear II into mesh with the reversing larger wheel E', for the purpose of ruiming the piston quickly out of the filling-tube, which then is charged with bran, the sack-cover placed on top of the tube, and the compressing action repeated, as before.

A sufficient pressure may be obtained by this compressor to reduce the bulk of the bran in the sack, so that its weightwill be even greater than a sack of like size filled with the grain itself, and the bran may be compressed, as described, into sacks or packages of both small and large dimensions.

The compression, place without the bran coming in contact with the sides of the sack and without any strain being thrown upon said sides, and the bottom of the sack is also supported from strain by its resting on the floor or base of the compressor,

it will be observed, takes and the cover of the sack is secured while the 1 bran is under heavy pressure.

I-Iaving thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a compressor, the combination, with the sides A, baseB, and reciprocating piston J', of the filler-tube M, receiving within it the piston, the sack S, receiving the tube extended to its bottom, a detachable cover, S', and the clamp T, substantiL lly as shown and described.

2. In a compressor for compressing bran and other substances into or within packages, and in which the material to be compressed is supplied to and compressed within the package without coming in contact with or straining on its sides, the combination, with a raising and lowering iilling-tube, ranged to work within and in and out vof the charging end of the same, of diierent speeding-gearing for operatingthe piston at different velocities in either or both directions of its travel, essentially as described,

8. The combination of the sliding gears E E F F', the rising and falling gear or gears H I-I', the wheel I, constructed to operate as a nut, the screw-threaded piston-rod J, the piston J', the filling-tube M, made capable of being yraised and lowered, and the clamp T, substantially' as and for the purposes herein set forth G 'ENV t* A.
