PATENT QFFIGE.
EDGAR ROUSE SUTCLIFFE, OF LEIGII, ENGLAND.
.RICKNIAKING-NIACHINE.
Specification of Letters Patent.
ratented March 5, 1967.
Application led October 22, 1906. Serial No.` 340.063.
To ctZZ whom it mwyconcerm Be it known that I, EDGAR RoUsE SUT- CLIFFE, a subject of the King of Great Britain, residing at Leigh, in the county of Lancaster, England, have invented certain new and useful Improvements in Brickmaking- Machines, of which the following is a specification.
This invention relates to the construction of 'means for enabling the plunger of a brickmachine to enter and leave the molds in a revolving table without the risk of damage to the machine.
It is more especially applicable to the apparatus for which an American patent, numbered 744,430, has been granted to me and to which it is shown attached, though it also is capable of being adapted to other machines having a revolving table.
It is found in forming bricks or blocks up on which a very great pressure is brought to bear that better results are obtained if both a top and a bottom pressure on the material is used. This necessitates the top plunger entering the mold in the revolving table, and so great are the forces made use of in machines of this class that serious damage to the apparatus may result if the table is not exactlyin position for the plunger to enter the mold when brought under the press-head or if the table commences to revolve before the plunger is clear of the mold.
The object of this invention is to construct apparatus which allows of a top pressure being exerted on the material by the top plunger entering the mold, and thus of obtaining a better pressed brick or block.
The accompanying drawings illustrate the invention applied to a revolving-table brickmachine.
Figure l shows in side elevation the toggle mechanism connected with the top and loottom plungers and the safety apparatus. Fig. 2is a plan of the safety apparatus. Fig. 3 shows the safety apparatus formed with slotted links and the dummy mold-box. Fig. 4 is a front view of Fig. 3, and Fig. 5 is a plan view of the dummy mold-box.
It will be seen on reference to Fig. l that Athe top plunger 0 is just within the mold in the table 12, being supported therein by the bottom plunger 8 and the compressed material, and that before the table can move on the top plunger must be raised. This is accomplished by means of the bowls i g', interposed in the path of the extensions 7L and ig of the toggle-joint pin 45. As the crank 10 in its rotation moves the connecting-rod 3 to the left these pins h and ;g surmount the bowls i and y', and the toggle-joint being connected with the plunger mechanism raise the plunger clear of the table while moving on to bring the next mold into position. The bowls 'i and j are supported by a bracket a, which is supported at one end by the screwed eyelet-rods b and c, iixed in the bracketsf, attached to a stationary part of the machine framing and so that they are adjustable therein by means of their screwed ends, and the lock-nuts thereon. The other end of the bracket a is supported by pins d e, ixed to the framing about which the bracket can turn as about a hinge to allow of the adjustment of the front end. Since the bottom plunger 8 may push up the material above the surface of the table before the descent of the to'p -plunger o, a dummy mold pis provided, which surrounds the top plunger and is kept in con'- tact with the surface of the table by springs r r, (see Figs. 4 and 5,) working in the recesses g g. The material is thus retained and may be pushed back into the mold proper by the top plunger. Instead of springs lugs may be provided on the machine to prevent the molds p rising. The plunger 0 having been raised after pressing the table is moved on until the next mold comes beneath the presshead, and in order to make sure that the mold-opening is exactly beneath the plunger for the next pressing, a series of holes are made near the edge of the table and a peg -7c is provided attached to the mechanism operated by the pin l4,which raises and lowers the preliminary plunger 6. This pin is tapered at its end and is provided with a spring m behind it, pushing on the collar Z, so that as the hole reaches the peg the tapered part enters, and upon the spring forcing the whole peg into the hole the table will be drawn exactly to the position for the plunger to enter the mold. rI'he pin remains in the hole until the rise of the preliminary plunger, when the pin is also withdrawn.
A modified form of apparatus for raising the plunger is shown in Figs. 3 and 4, where instead of bowls xed pins t t are held in brackets u u, attached to a stationary part of the machine. On the toggle-joint pin 4,5 on each side of the toggle rods s s are pivoted,
being provided at their bottom ends with I-'r'o IOO slots v, which work over the pins t t. Upon the connecting-rod moving to the left the pins will come against the ends of the slots and upon the continued movement of the connecting-rod will raise the pin 45 vertically, as the pin 45 is connected to the plunger o. This also will be raised clear of the table, which can then move on for the next mold to be pressed. By this means the great advantages accruing irom both a top and a bottom pressure on the material are obtained, and all risk of injury from premature movement of the table is prevented, since the table is turned by the same shaft which eii'ects the raising or the plunger.
I am aware that prior to my invention pressing-machines have been made with stops entering a notch in a'revolving table. I therefore do not claim such a combination, broadly; but
What I claim as my invention, and desire to secure by Letters ratent, is-
