To a/ZZ whom it may concern.-
Beit known that I, SIMEON OAKEs HOLMES,
England, have invented new and useful Im-` provements in Presses for Preparing Block,
Fuel and for other Purposes, of which the following is a specification.
This invention relates to the use in the manufacture of block-fuel of presses employed for compressing the materials so as to form suitable blocks. I use a rotary table constructed as hereinafter fully described for. carrying the molds and stamps which are thereby brought in turn into position for charging, compressing, and discharging.
In order that my invention may be more fully understood and carried into practice, I Will now proceed to describe the same with reference to the accompanying three sheets of drawings, in all the figures of which like reference-letters are employed to distinguish similar parts.
Figure 1 is a side elevation, and Fig. 2 a plan partly in horizontal section, of a press constructed as used by me. Figs. 3 and 4 are detailed drawings of the rotary table to be hereinafter more fully described.
The molds in which the fuel composition is compressed are mounted in groups of any convenient number at the ends A, B, 0,'D, of a number of tubular equidistant radial arms, which, together with the rim T, constitute the rotary table. Though but four of these equi-` distant radial larms are shown in the draw.y
ings, any number maybe employed; and itis I l and keyed to, the horizontal shaft Q jouradvantageous so to arrange them that while two are vertical, two are horizontal. For convenience of manufacture the rotary table is shown made in one casting. It will be readily understood that lthe molds are supported only by theradial arms of thesaid table, the rim T being, as already stated, simply for the purpose of closing the orifice in the charging apparatus. If Adesired the said orifice may be closed by a sliding door or other suitable means, in which case the rim T may be dispensed with, the table then consisting of the radial arms only.
As shown in the drawings, each group A, B, C, D, consists of a single cellular casting .I of gun-metal or other suitable material. Thiscasting .I is inclosed within a cast-iron or steel socket K which'may be shrunk u upon, or otherwise permanently attached to, the said cellular casting J. It is obvious that each group of molds may consist of one casting, the object of the socket or outer casting K being to take the 4compressing strain to which'rthevmolds are submitted during the operation of compressing each charge, and thereby relieve the table-of such strain and allow of its being constructed in a lighter manner. Each group of molds is secured in position in the periphery of the rotary table-by means of set screws L as shown,
so that it may be readily removed when required. Each cell or mold of each group is provided with a solid stamp, ram, or plunger E made to fit freely within its respective mold. The stamps E are so arranged that their ends never leave the molds, the inner vends of which are thereby always closed. All
the stamps E for each group of molds A, B, C, D, are carried by a stout plate or bearer F to which they are secured by bolts Gr or other suitable` means. These plates F are fitted within the hollow arms of the rotary ta ble so that they may slide freely therein and, in so doing, carry the stamps E backward and forward in the molds. these plates or bearers F are extended so as to pass through slots in the sides of the arms of the rotary table, against the edges I of Vwhich they take their bearing, and project into the. path of lugs A on the reciprocating slides Z. l l
The rotary table described is mounted upon,
naled at R in the bearings of the main casting or frame Work P. The shaft Q, and with it the rotary table, is intermittently rotated The ends H of by means of the pawl J actuated by the crank disk I on the main shaft S and taking into a ratchet wheel on the said shaft Q. This ratchet wheel consists of two disks L held apart from one other by a suitable distance piece and connected by as many equidistant studs or pins K as there are arms in the rotary table. The pawl J Works between the disks L and engages in turn with each of the studs K. The parts are so arranged that the pawl J acts tolbring each group of molds IOO A, B, C, D, in turn opposite the stationary pressing block B2, one of the said groups being brought to this position for each revolution of the main shaft S. The main shaft S is journaled at U in bearings in the frame P and carries, besides the crank disk I already referred to, two eccentrics V with their straps XV the eccentric rods of which are connected by means of pins Y with the slides, blocks or shoes Z Working within guides projecting from the inner sides of the framework P. It will be seen that the rotation of the shaft S, through the eccentrics V imparts a reciproeating motion to the shoes Z. Though I have shown the eccentrics V in the drawings it is obvious that cranks may be employed for the same purpose. As shown at Fig. 2, the shoes Z are placed one on each side of the rotary table with their lugs A projecting inward toward the said table so as to engage with the extended ends Il of the stamp supporting plates F previously7 described. The main shaft S receives its motion from the first motion or driving shaft D', E', through the spur wheel Il and pinion G. The driving shaft D', E', is provided with a iiy wheel F. M0- tion is transmitted to the machine by means of belt, toothed, or other suitable gearing connecting the driving shaft D', E, with the motive power.
The caps of both thebearingsinclosing the journals U of the main shaft S form parts of the casting XV carrying the abutment or thrust block `B2 against which the fuel coniposition is pressed by the stamps E. This casting lV is held in position against the thrust of the said stamps by the four tie-rods which also serve to keep the caps Z of the bearings of the shaft Q in position. These tie-rods are provided with nuts Y at both ends by means of which the parts may be tightly drawn together. Strong springs A2 are interposed between the casting XV and the nuts Y', so as to allow of the parts yielding slightly in the event of some uncompressible material accidentally gaining access to the molds. The greater part of the weight of the casting W is taken by the bracket N upon which its lower face rests.
Pivoted at M to each of the eccentric straps XV are connecting rods N one foreach eccentric, which are each connected to a lever P pivcted at R to the bracket Q. It will be readily seen that the movement of the eccentrics acting through the rods N causes thelevers P to oscillate upon their pivots R'. The lower ends of the levers P carry rollers S', which, in their outward movement bear against the inner sides of the ends H of the plates F carrying the stamps E and act as pushers to drive them outward to discharge the finished blocks of' fuel from the molds. It will be seen that this operation takes place simultaneously with the compressing of the contents of the opposite group of molds to those discharged, the 011e movement of the cccentrics effecting' both operations.
The opening by which the composition is discharged from the said pan is in immediate contact with the rim T of the rotating table. It will be readily seen that this rim T prevents the composition leaving the pan by acting as a sliding shutter to the said opening. In Fig. l the lower portion of a pan is indicated by dotted lines over the upper part of the rotating table. A curved guard or shield C2 extends from the outlet of the pan to the thrust block B2 and serves to prevent the escape of the full composition from the molds in their passage from the charging to the compressing point.
In use, one of the group of molds is brought beneath the outlet ot' the pan as shown at A Fig. l, and. the composition caused to enter the molds. Motion is then communicated to the machine and with the last half of the first revolution of the main shaft S, the rotary table is turned through a quarter of a revolution (when as shown in the drawings it has four arms) by means of the pawl J. The table then remains still While the main shaft makes another halt` revolution during which the molds carried by the next arm of the table are being filled from the pan at A, and at the same time, the eccentrics V are acting to compress the contents of the first group of molds and to discharge the. finished blocks M from the molds at D which are diametrically opposite to those being compressed in the manner already fully described. With the next half rotation of the main shaft S the rotary table is given another quarter of a revolution which brings those molds last discharged into position for charging (the stamps E at the same time falling back of their own weight) those last charged into position forcompressing and those the contents of which were last compressed into their lowest position. Vith the next half revolution of the shaft S charging, compressing, and discharging, is effected as before described. The rotary table is then again shifted so as to bring the compressed molds into position for discharging and others to the charging, compressing, and lowermost positions as before described. These opera tions are repeated in regular order While the machine is in motion.
The table may when necessary be held at the right point for each compressing operation by providing the rims of the ratchetdisks L with a number of shalloW-indents D2 into which a spring latch E2 drops as the said indents are brought before it, so as to prevent the further rotation of the table. The said indents have flaring mouths so that the latch.

- is driven out from them on motion being It will also be understood that the points of.
charging and compressing maybe arranged at any suitable relative position to one another and not necessarily at right angles.
For instance, they may be placed at any angle with one another or directly opposite each other in a line. It will also be readily seen that the general arrangement and construction of the various parts of the press other A than the rotating table may be varied Without departing from my invention.
