SPECIFICATION' farming part of Letters Patent No. 290,013, dated December 11, 1883.
Application filed October 15, 1983. (No model.)
To all whom, it may concern:
Be it known that I, Josnrn ELDER, a citizen vof the United States, and a resident of Peoria, Illinois, have invented an Improved Mode of and Mechanism for Packing Bran, 81e., of which the following is a specification.
My invention consists of a mode or process, fully described hereinafter, of packing-bran for transportation, and also of certain mechanism for carrying this process into effect,'the process and mechanism being so fullyexplained hereinafter as to render a preliminary description unnecessary. K
In the accompanying drawings, Figures 1v and 2, Sheet 1, are diagrams illustrating the main feature of my invention; Figs. 3 and 4. exaggerated sectional views, showingthe manner of turning the edge of lthe can; Fig. 5a vertical section of a machine which I prefer to use in carrying out my invention; Fig.' 6,
7,-a sectional plan on the line 1 2, Fig. 6.
The main feature of my invention may be best explained in connection with Figs. 1, 2,
3, and 4, Sheet 1, in which A represents a cylinder containing a piston or plunger, B,
which may be operated by hydraulic pressure, or by any mechanism such asis used in connectionwith ordinary presses,the cylinder having, in the present instance, a bottom plate, e, which is removable or pivoted, so as to be turned to one side, and which may be locked in place by any suitable devices. A sheetmetal can D, closed at the bottom and open at the top, is deposited in the cylinder and rests on the plate a. A disk, b, of sheet metal, to form the top or cover ofthe can, is attached to the under side of the piston, preferably in the manner described hereinafter After the cylinder, as well as the can D, has been filled with bran or other material of like consistency, the piston or plunger and the disk b, attached thereto, are depressed, thereby tightly packing the bran into the can, and thrusting the. disk a short distance into the same, the pressure of the piston being continued, so as to force the upper edges of themcan inward and bend them i over the edges of the sheet-metal disk, which is thus firmly secured, after which the plate 5o a is unlocked, so as to permit the packed can Sheet 2, an enlarged view of Fig. 5; and Fig.'
'invention in the machine'shown in Figs. 5,6,
to fall or be forced through the bottom of the cylinder. K y
rlhe manner in which the disk is secured to the can isv shown in the exaggerated sec-- tional diagrams, Figs. 3 and 4.'
In Fig. 3, D represents a portion of the upper edge ofthe sheet-metal can, this edge being slightly bentinward, as shown. A die, B', is secured to the under side of the piston or plunger B, and the under side of this die has near its cdgean annular recess, e, bounded by the annular inclined rib j'. rlhis recess and the rib by which it `is bounded may be I formed on the piston' itself; but I prefer to use a die attached to the piston in anyconvenient manner. s The disk b is carried'by the die,being temporarily attachedthereto. As thc piston descends and compresses the material into the can the disk is thrust into saidcan, and the rib f of the die then bends the edge of 7o the can inward, thereby effectually preventing the escape of the disk when pressure is removed from the contents of the can.
I prefer to embody the main feature of my and 7, which I will proceed to describe.
A long casing, A, Fig. 5, preferably of cylindrical form, has at each end a hydraulic cylinder, h, for a. plunger, t', attached to or forming part of the piston B, which is arranged to slide'in the long cylinder. Suitable pipes carry water under pressure from any suitable pumping mechanism to the two hydraulic cylinders, so that both pistons may be moved toward or from each other. At or near the middle of the long cylinder a portion of lthe same is-cut away, leaving an opening into which the can-blank to be filled may be in toduced, the opening being furnished with suitable doors, referred to hereinafter.
Adisk having been placed on the die of the upper piston, and a similar disk on the top of the die of the lower piston, both pistons are retracted, and a can-blank, which is simply a hollow cylinder of sheet-iron open at bot-h ends, is introduced into the opening in the large cyl inder A', so as to rest on small yielding dogs m. The opening in the cylinder A having been closed, the bran is introduced into a hopper, and is permitted to flow therefrom into roo v the large cylinder until the latter and the canblank are filled, after which the gate w of the hopper is closed and the pistons are moved toward each other until the entire mass of bran is compressed within the can and the two heads secured to the same by the dies of the two pistons in the manner described above.
Figs. 6 and 7 are enlarged views of the middle portion of the cylinder, n being the opening for the reception of the can-blank and for the withdrawal of the iilled can; M, two doors hinged to the cylinder, the upper edge of each door having a rib,p, to overlap and iit snugly to the rib q on the cylinder, and the lower edge of each door having a similar rib to underlap a rib on the cylinder, so that when the doors are closed and secured by any appropriate locking devices they will enable the cylinder, which is necessarily weak at the opening, to resist the tensile strain to which it is necessarily subjected. Each dog m is partly contained within a pocket in the cylinder, is pivoted in the bottom ot' this pocket, and is connected to the back ofthe same by a spring, which tends to force the upper end of `the dog outward, but prevents it from falling out of the pocket. There are preferably three of these dogs, which yield as the lower piston is completing its upward movement.
There are several ways of temporarily connecting the top disk to the under side of the upper pistou; but l prefer to make a small lip, t, 011 the cover by forcing outward a portion of the same, and this lip may be hooked onto a projection in an orifice in the die or piston, the lip being withdrawn from its connection with the piston, when the latter is retracted, after the cover is secured.
I am aware that materials have been packed into a cylinder by pistons operating from op posite ends of the same 5 hence I disclaim this feature. I also disclaim the heading of cans by pistons or disks operating in contrary directions while the body of the can is under connement.
I claim as my invention- 1. The mode herein described of packing bran and other material into cans, the said mode consisting in forcing into a can-blank, while it is under coniinement laterally, both the bran and cover or covers of the blank, and turning the edge or edges of the blank while pressure is being applied to the bran, substantially as set forth.
2. rlhe combination, in a machine for packing bran and other material into cans, of acylinder or casing, A, with a piston or plunger adapted thereto, and having at or near its edge an annular recess, e, bounded by an annular rib, f, substantially as set forth.
3. The combination ot' a cylinder having a communication with a hopper, and a lateral opening having a door or doors, M,with two pistons, one on one side and the other on the opposite side ot' the said opening, and with mechanism for moving the said pistons simultaneously toward each other, and for retracting the said pistons, substantially as specified.
4. The combination of the cylinder and its lateral opening and the ribs q on the upper and lower edges ot' the said opening with a dooror doors having ribs p, substantially as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
