To all 'whom i may concern:

Be it known that I, CHRISTIAN KORTE, a subject of'the King of Great Britain, andV resident of Leeds, in the county of York, England, have invented a lcertain new and useful Improvement in Briqueting-Presses, of which the following description, having reference to the accompanying sheets of drawings, is a specication.

In the working of metals such as in the turning of shafts of steel, wrought iron or the like, curled strips of considerable length so that they are diiicult to handle to bring into such a state that they may be again made use of. The object of my present invention is the production of means as will enable me to take such curled strips of metalA and form them into briquets so thattheir subsequent treatment may be carried out in manner well known. l

My said invention consists in theJ production of apparatus into certain parts of which I may place' bundles of these cuttings, c Xercise pressure over them to press them into certain flat or slabformation from which I then cut or shear portions of such forms,

shapes or dimensions as will enable me afterward to mechanically transfer said cut-off portions to dies, where by pressing tools they are finally acted upon so that they are there- 'by brought into the condition or briquet formation stated. l In` the accompanylng sheets of drawings Figure 1 is 'a side elevation illustrating my improved apparatus, certain of the parts being shown in section in order that parts behind may be more clearly illustrated.

Fig. 2 is a plan of arts shown by Fig. 1 and again certain of tlhe parts are cuit away so that the parts beneath might be seen.

Fig. 3 is a sectional elevationftaken on an irregular line) of the main pressing and shaping apparatus while Fig. 4 is an elevation of the parts shown by Fig. 3, as seen in the direction indicated by the arrow a.

In carrying my invention into effect, I make use of a receptacle 2 which is somewhat of the character well known as being used in connection with baling apparatus. This receptacle 2 is mounted so that its wheels 2a may run on rails 3| from the yposition beneath the hopper or chute 4 as shown in full lines Fig. 1 to occupy a pothe parts cut away are often in thin the accompanying drawings. In this feed-- mg apparatus a pit 5 may be appropriately formed or it may be dug into the ground in va yard or space adjoining the building in which my improved apparatus is mounted and leading from this pit 5 is an inclined trough 6 preferably of sheet metal. This trough 6 terminates at the edge of t'he mouth piece 4a leading to the hopper 4. Through the lower part of thi-s pit 5 and along the trough 6, over the top of the mouth piece 4el and takingover the driving sprocket wheels 7 and other guiding wheels 8, 8a and 85, are chains 9, 9a the two Shown being endless and having on their outer surfaces cross- 'bars 1() which extend between them and above them as shown 'by Figs. 1 and 2. Thus as the curled strips of metal which are to be briqueted are deposited in the pin 5 they are carried by these slowly traveling chains 9, 9a and their crossbars 10 until they reach the hopper 4a where they will immediately descend down the chute 4 into the receptacle 2. The motion transmitted to .the chains 9, 9a may be derived from any prime motor through a belt 7a which rotates the pulley 7", and by the gearing wheels 72.7d and 7e transmit the motion to the chains as desired. As :the curled strips of metal are deposited into the receptacle 2, a workman by employing a bar of wood or metal will force such strips down in the sai'd receptacle 2 in order that same maybe, in a certain measure, compressed therein while resting upon the stationary base or support 2b beneath. When the receptacle 2 is su'liciently charged, the workman then forces it or causes it to travel over the rail-s 3 into position within the press as illustrated by Figs. 3 and 4 and during its passage from one position to the other its contents are retained within it by the base 2b and a plate 2c forming an extension of said base. On reaching its position within the machine, its base is formed by a tab-le 13 which is mounted upon the rams 14, 14a, 14b which act within the hydraulic cylinders Patented Feb. 4, 1919.

15, 15b. 15a, 115b are sup-ported by a suitable base while, by the vertical columns 16, 16, 16h, 16, the head 17 is firmly and securely connected to said hydraulic cylinders. Beneath the head 17 is Amounted a block or plate 12 within a shield y19.

In this hea'd 17 is formed another hydraulic cylinder 18, the ram 13a in which extends vertically through an appropriate opening within the pressure plate 12 while a oorresponding opening 13u is made in thetable 13. At the end of the ram 18a-areqmounted two shearing blades b and c while within the opening 13a are mounted two other shearing blades d and .6 which .aie ar.- ranged to act asI hereinafter described. The shield 19 which surrounds the plate 12 has elongated openings made laterallythrough it for the pressure plates 20, 20a the ram 29L and the discharge material y moved .by said ram, to pass through so that 1 cylinder may enter table 13.-

bearings 24 in the said 'devices mayV operate beneath the pressure plate 12 and above the tab-le 13 when this latter is in its raised position hereinafter described. .The pressure plates 20, 20a are mounted upon rams 21 and 2 1a respectively and these operate within their hy- -draulic cylinders 22, 22a.

At the rear of the machine a having a ram 291 that said ram, on

cylinder 29 being forced out of its the opening 13a 1n the Mounted upon -a horizontal shaft 23al is a rotary die plate 23 which is supported by its front of the several hydraulic cylinders hereinbefore referred to so that as this circular die plate 23 is rotated each Vof metal h in order to of the molds f formed therein may be successively brought opposite the opening 13a made within the table 13. The die plate 23 is manually rotated byfthe handle 25b which is iXed upon the shaft 25 upon which is also fixed a pinion 25a arrange-d to gear with teetliyformed on the periphery of said die plate 23. Fixed upon Suitable ibase pieces and bearings 26, 26*1 are two hydraulic cylinders 27, 27 a the rams of which are in alinement with one or other of the molds f When another of said molds diametrically opposite to it is opposite the opening or space 13a in the table 13. A.

The actions of the several parts herein'before described are as follows Prior to the workman moving the receptacle 2 over the top of the table 13 (when this table is in its lowest position as shown 3) he will have placed in the rectangular opening 13 a solid bar fill said opening so that the table V13 will by its aid present a flat unbroken surface to the contents of the receptacle 2 in order to press same into a slab against` the plate 12 by risinglinto the' These hydraulic cylinders 15,

is mounted in position so l other shearing l13a into the mold f in the position shown in full pletion of said pressing actions, said table 13 will have reached -the position shown in full lines Fig. 3. When the table 13 has reached this position the contents of the re ceptacle 2 will have been moved into or within the shield 19 to form a slab of material of a thickness corresponding to the space b tween the upper surface of the table 13 and he lower surface of the plate 12.

The operator will then cause the ram 29awithin the hydraulic cylinder 29 to advance and press-the block h out of its position within the table 13 into that mold or opening j' in the die-plate 23 that happens to be opposite to itand in position'to receive same. rlhe ram 29L is then caused to ,re-

' cede so that" the space 13a Within the table 13 is left vacant,

p. and at this time water is admitted to the cylinder 18 so that the ram 18a commences to descend and shear ol siicli l lines Fig. 3. After` the block 71. has been-.placed inmthe position 4 into position over the this table will support a portion of the slab of compressed material above the table 13 as might lie within its path, the shearing blades b, c on this occasion lacting in conjunction with the blades d, e so tliatthe portion of the slab of pressed materialcut off is forced down into the space 132l in the table 13. Now-,Water pressure is admitted to the cylinders`29 so that the ram 29'a on 'commencing to advance will force thecut off portion of material from the opening die plate 23. This first cut-oli' portion of material to enter the mold f will force the block of metal h that had been previously carried into same, beyond said mold.

h is thus forced out of its position in the die plate 23 it may be received by any appropriate support admit pressure water to the two cylinders rot Thus it will be clear of the die plate 23. When this block of metal l where it may remain until the operator again requires it,as herein- 22 and 22a so that the pressing plates 20 20a s u are caused to advance to force the remainng'portions of' the slab of compressed cuttings between the table 13 land the pressing plate 12 so far forward that they will close the -spacefiom which the ram 18a had previously cut the portion which was then suppliedl to the v.mold f in the die plate 23;

\ opened so that the and the step forward that the operator has moved the plate 23, to bring another moldf opposite the opening 13a in the table 13, enables him to bring the next mold f into position, while at the same time he will have opened the valve leading to the pressure cylinder y18 so that the ram 18*l will again cut ofi' another portion of the curled stripsof metal overhanging the opening 13 in the table 13. Ait ythis time, the operator again causing pressure water to enter the cylinder 29 and its ram 29a will advance to force the cut-off material from the opening 13l into the mold f waiting ready to receive it. The operation of closing up the material between the table 13 12, the cutting-ofi' of said material and the charging of same into the die plate 23, are repeated until the which was first supplied with this material opposite the rams The water-pressure valves are now to be rams from these cylinders 27 27a are caused to advance one on one side the die plate 23 and the other on the other side thereof so that the contents of the mold opposite are compressed in both directions by these rams and that to the desired extent. The operator then shuts off' the pressure water from one of these pressure cylinders, say cylinder 27a, but allows the pressure water to act within the other pressure cylinder 27. continues its motion and ejects the compressed 4briquet from the mold. The pressure water within the cylinder 27a will now be reversed so that it will cause the ram therein to release its pressure upon the discharged briquet (which up to this time will have been held between thetworams) so that this latter is thereby permitted to fall into any place or receptacle arranged to receive it. The operator then proceeds with the advancing of the die plate 23 together with the carrying out of the several functions herein'before described in connection therewith until the last or final portion of the material compressed between the table 13 and plate 12 have been exhausted or depleted. The valves are now again opened to enable the pressurewater to cause the table 13 to descend by removingv said pressure water from the cylinders 15, 15a, 15P on which the receptacle 2 is moved and placed beneath the hopper 4, the block of metal being `again replaced in the opening 13a within the table 1 3, to vreinstate all the parts 1n their original orinitial positions for the full series" of operations to be recommenced.

For the convenience of the workman who has to operate the valves which govern the `actions of the series of rams in the mechanism hereinbefore described, I [have the valves connected and the pressure platedieplate brings the mold in the cylinders 27 27a. v

- pillars for supporting `said Thus the ram therein I sure plate to levers 30 which are situated near the handle 25" where the workman stands to operate the die plate 23.

Although I have described said apparatus as being controlled entirely by the workman through the levers and other devices hereinbefore described itis obvious that 4many parts of the apparatus might be madeto operate or work automatically under the actions of the pressure water by the employment of valves for controlling such pressure water somewhat of the character already known and which I have described in previous specifications of British patents granted to me and another for this class of appara.- tus, viz: in No. 7365 of 1911 and in No. 16826 of 1912. As the curled 4strips of metal vary in length and volume to a great extent it may be necessary that the chain which is used for feeding said material to the hopper 4 may be required to travel in a path at a greater or less distance above the base of the inclined chute and to enable me to do this I make the guiding bowls or pulleys 8b so that I may adjust them in order to raise or lower said chain relatively with said chute. Or I may make use of adjustable chute so that I may extend them when it is desired to raise the chute, or I ma-y reduce their length when said chute has to be at a greater distance from the chain.

Such being the nature and object of my said invention, what I claim is 1.
