Application filed. May 4, 1907. Serial No. 371,947.

To all whom it may concern:

Be it known that I, OCTAVE CROCHET, a citizen of the Republic of France, and resident of Alais, France, have invented a new and useful Improvement in Agglomerating- Machines, which improvement is fully set forth in the following specification.

This invention relates to a press with two rams and an intermittingly revolving molding table with molds open on both sides, in which one of the rams is driven directly by means of a hydraulic piston which is under hydraulic pressure capable of regulation, and the other by the hydraulic press through the medium of a lever system, and both rams exert a simultaneous double pressure on the material to be pressed which is contained'in the molds.

In the invention a double transmission of the regulatable pressure of the press cylinders is striven for. To this end the lever driving the upper ram is so connected by means of crank drivers with a compression piston which the fluid in the press cylinder places under regulatable pressure, that the respective lever arm makes a strokecorresponding to the stroke of the compression piston and therefore always even. On the other hand a special hydraulic piston likewise exposed to the regulatable pressure of the press cylinder operates on the other arm of this lever.

Figure 1 shows a side view of the briquet press. Fig. 2 is a plan view. Fig. 3 is a section on the line AA of Fig. 2. Fig. 4 is a cross section on line B-B of Fig. 2. Fig. 5 is a cross section on the line CC of Fig. 2. Fig. 6 is a cross section through the connection between the press pot and the valve box.

In the lower part of the frame are three

cylinders

6', 11, 8, connected with each other. In the cylinder 6 operates a compression piston 6 driven by a cranked shaft 1; in cylinder 11 operates the hydraulic piston 11 bearing the press ram 10, and in the cylinder 8 operates the hydraulic piston 8 connected with one end of the lever 4.

At one end of the cranked shaft 1 is a toothed wheel 1 in which engages a second toothed wheel driven by a motor. To the crank of shaft 1 are attached two driving rods 2 extending upwardly and to which are attached a bar 3 borne by one end of the lever 4. To the crank is also attached a driving rod 5 extending downwardly and to which is linked a sliding shoe 5 which bears underneath the hydraulic compression piston 6. The other end 7 (Fig. 1) of the lever 4 is connected by means of a rod 7 and yoke 7 to the hydraulic piston 8 (Figs. 3 and 5). Secured to the under side of the central part of lever 4 is a semi-cylindrical pressure piece 4 which operates upon the upper press ram 9, (Fig. The lower press ram 10 is connected at its lower end with the hydraulic p1ston 11 which rests upon an elastic cushion 18.

A valve box 12 is in communication with the three

cylinders

6, 8 and 11 and this box contains an inlet valve 15 and an outlet valve 16, the inlet valve controlling the flow of water to the box and cylinders from a suitable supply. A plate 13, capable of be ing revolved on a table 13 around a cylindrical frame piece 14, (Fig. 5) bears a certain number of mold openings (Figs. 2 and 3) lying in a circle, of a size corresponding to the cross section of the press rams. This plate 13 intermittingly rotated by means hereinafter described comes to rest in a position in which one briquet can be pressed in one opening and a finished briquet out of another and the press rams withdrawn in order to allow the plate to again be given a partial revolution.

The molding of the briquets is accomplished in such a way that the cranked shaft 1 when its crank goes upward and the press ram 9 moves up raises the hydraulic compression piston 6, whereby the suction or inlet valve 15 is raised so as to fill the press cylinders. At the beginning of the downward stroke of the crank shaft the suction valve 15 is closed, andthis movement being maintained, the upper press ram 9 is moved downward, and under the action of the'hydraulic compression piston 6 the lower press ram 10 is moved upward, and under pressure of both rams 9 and 10 the material contained in the mold is pressed.

For each kind of material the pressure must have for the measuring unit of surface, a measured strength. The pressure or outlet valve 16 (Fig.1) opens downwardly and compresses by means of its rod a plate spring 16 which presses against the valve box 12 and said spring can be adjusted by a nut and a check nut 16*, according to the measure of the pressure which is to be attained on both sides of the briquet. safety valve1'7 (Figs. 1 and 6) with weighted rod 17 a and a manometer 18 (Figs. 1 and 6) serve for the supervision of this regulati on. The measurement of the longer arm of the lever 4 and the diameter of the compression cylinder (5 are so'proportioned that the lift of the lower press ram 10 amounts to only two-thirds of that of the upper press ram 9.

If the pressure for the measuring unit of surface exceeds the determined measure, the valve 16 allows water to flow from the box 12 until equilibrium in the press cylinders isposition by the springv 20 which has been compressed and by the water flowing into the boX 12- and: acting on piston 8. There cannot therefore be produced an excessive pressure. leading to the injury of the parts of the machine. Thepiston 21 effects the ejection ofthe briquet from the mold. This is movedby a link 22' (Fig. 1) attached to oneend' to the-lever 4 and with its other end attached to a lever 23capable of turning on 27.v This operates by means ofthe rod- 24 on a lever 25 capable of turning on 28 (Fig.

which by means of the rod 26 is connected to the; upper end of the rod of the piston 21-. The movement of the ejecting piston 21 is therefore independent of; the hydraulic regulation. Therefore a briquetis with certainty ejected each time from the mold. j j

Theintermittent revolution of the molding-table plate 13 is transmitted by theshaft 1. One ,endof the latter bears a crank 29 (Fig. which by means of a driving rod 30 moves a sliding piece 31, which slides in a: guide. A fork 33 of the sliding piece embraces constantly apin 34, the end of which is fixed on a two-parted collar 35, which is revolved back and forth in a circular groove of the molding table plate 13 by means of the-crank and driving rod:

.In the groove of the molding table plate there are a number of teeth corresponding to thenumber of molds on which the pawl 36 which is fastened to the ring 35 operates. By this means a partial revolution of the molding table plate is produced at each revolution of the shaft 1. On the front part of the sliding piece there is an adjustingsc'rewf38, which. at the end of the revo-' lution of the molding; table 13 strikes the arnrof a trigger-pin 37 and this presses into a depression 38 of the plate. The latter is In the upward movement of t-hen'stopped exactly at the moment inwhich I the briquet' to be' pressed finds" itself oppositethe'two pressrams 9 and 10.

It sometimes occurs that on account of too strong friction of the lower press ram 10, that this does not fully withdraw from the. moldingtab'le 13 and thus hinders themove ment"of the tablei- In order to avoid this a 'roll' 39 (Fig. 2) set on an opposite arm of the crank 29 acts on the arm of a lever 40 (Fig. 1') the other arm of which is connected by means of a rod 41' with the arm 42- whose axle carries a pressure lever 43. This-,under, the action of the roll 39, presses u'pon' thebottomof a notch in the rod connecting the hydraulic piston 11 with I the press ram 10' and: withdrawsthe latter from the opening of the molding table 13;
