TO ALL WHOM I'l MAY CONCERN:
Be it known that I, JOHN McDONALD, of the city and county of New York, and State of New York, have invented certain new and useful improvements in BrickiPresses; and I' do hereby declare that the following is a full and exact description thereof. y, i l
I My invention relates to that class of brick-presses which are' adapted for rta-pressing the'material after it has been previously pressed or moulded, and subsequently ldried orprtially dried. I willirst describe` what; consider the best means of carrying` out my invention, and will afterwards designate the points which believe to he new. The accompanying drawings form a part of this specification. i 'i Figure l is a side view of my press with the platen raised. I A o Figure 2 is an end elevation, partly in sectiom-representng the press in the same condition.
Figure 3 is a' side elevation, representing my press with'the platen depressed. v
Similar letters of reference indicate like parts in alll the figures. Tints are 'employed merelyto aid in distinguishing parts, and do not indicate materials. The materials of the whole may be iron and wood.
A is a framing of wood, mounted on wheels a, tomake it more conveniently propelled, and havingan upright guide, A 1, of cast iron, properly compressed, and securely bolted to the other`- portion of the framework. B is a slide, which embraces the upright guide A 1 at its upper end,- and is guided near its lower'lend by passing through the framework A, which carries a. stout horizontal arm, B 1, which formsa platen to the press. C is s link, which connects the piece B to a ,crank .in the rocking-shaft D, which latter is'operated bythe tender by means of a lever, D 1. E is a movable bed-piece, supported onI a spring, e, with .liberty to rise and sinkto a small extent, as represented. The partially-dried brick is placed upon the` upper surface of the part E, which latter should be very nearly as large as the brick. The descent of the platen B 1 compresses the brick ilatwise between them. Thesprug e yields by its elasticity as th'e'pltiten descends, and forces the brick downiupon the bed.piece E, and thus allows the latter to be supported upon t'he'solid framing, A, which surrounds the opening. As the platen rises the brick andmovable bed E rise with .it'to a limited extent. When the bottom flanges E 1, which extend outward from the sides of the base of the `piece E, meet the corresponding anges, which project over them from the part A, its upward motion is arrested, and the continued ascent of the platen liberates the'brick, and allows it to be removed and another placed in its stead, after which the operation is repeated'. G1 G 2 are levers, turning on centres g, which are mounted in, theisides of the platen B 1. H isha corrersppnding lever, mounted on thepivot h; carried also on the platen B 1 J J J are links, connecting the upper ends of these three levers to the extremity of the arm A 2, which is secured on the upright A 1 ata point above the highest travel of the slide B. This arm A 2 is made adjust-able by meansiof the set-screw, as represented, so that itmay be changed up and down on the upright A 1,V and thereby vary the conditions under which the levers G 1, G 2, and H are operated. All these parts are so lproportioned and adjusted, as represented, that; while. theplaten B 1 -compresses the upper face of the brick, the lever G 1 shall'compres's one of its edges,`the lever G 2 compress the opposite edge, and the lever H compress one end. It is practica-ble, by addingaan'other 4lever, andmziking the framework more open, as will be 4readily understood by mechanics, to also'pro'vide an additional lever, and compress the end opposite the lever H ;v but I do not esteem this generally necessary. 4 The re-pressing of bricks as the operation is ,usually performed is imperfect, by reason, o'ffithe action being only on the two broad faces-tbc upper andjlower faceswhen the brick lies twisc. My pressybyacting on the edges at the same time, makes a more uniform pressure of the material, pressing it in ali directions. 'My
mechanism. consistingoi` the three levers, mounted on pins,rmoving with theplaten, and connected by links to acomuion adjustable fused point, for effecting. these moiiements, is very simple, and may be cheaply' constructed and easily kept in ord-er. l
The movements of the movable bed E, under the action of the spring e, accomplish the highly important end of causing the brick to ascend with the platen while the levers G V1, G 2, and H are being slowly turned on.
their respective pivots to release the edges of the brick from pressure. In the absence of this movement there would be a tendency to crumple the edges, but for the fact that the bed E lifts the brick during the early portion of the rise of the plate, and follows it until the respective levers have entirely released'their held on the edges und end of the brick, and leaves the material t `rest Withou employment of levers adapted to press the bricks on their edges,
t exposing it to 'any strain otherl than the direct compression. i
l Having now fully- 'describedmy invention, APatentl isgas follows:
1. II.claim, in combination with tbe platen B 1, or its equivalent, adapted to what claim as new tl1erein,'and desire to secure by Letters asG-1 `Gr 2, `with or 'without the end-pressing, lever'H, 'substntially as herein. specified.
2. I claim', in' connectionA with. the above, the within-described method of o say, mounting `the said levers on pivots g h, carried on the platen, and connecti of the adjustable piece A 2, or its equivalent, ali arranged for joint operation `In testimony whereof` I hve hereunto set my'hand in the presence of two perating said levers, that is to ng the upper ends of the levers as herein specified.
