This invention relates to a new and improved machine for moulding .and pressing bricks from untempered o'r dry clay, and it consists in a novel and improved means for receiving and discharging the moulded clay or bricks, and in an improved means for regulating the feeding of the clay to the moulds; and also to an improved e the same, reference -means for pulverizing or granulating the clay in order to insurey it being perfectly fed to the moulds; and
further, to an improved means for operating the plungers, which compress the clay in the moulds.
A represents what may be termed the base of the machine, and B is a box placed thereon, in which a semicylindrical grating or screen, C, is placed, andl hung upon pivots, a a. One of these pivots, a, has a crank, b, attached, which ips connected by a rod, D, with a 'crank-pulley, E, and through which the screen C is oscillated when the machine is in operation. F is a shaft provided with teeth, c, which are of curved form, and workv between the bars of the screen C. These teeth are placed and keyed upon the shaft F in such a position that their ends will form two spiral rows, the teeth being of S' Vform and placed centrally on the shaft F, as shown in iig. l. The teeth c project up between the bars of the screen C a suitable distance, as shown in tig. I, and the shaft F is rotated by a belt, G', from a shaft, el, on the framing H of the machine. I is an endless belt, which has buckets, e, attached to it, said belt working over rollers ff, and operated by a cross-belt, g, from a shaft, h, on the framing H. .I is a hopper, which is secured to two hprights, iz', attached t the base A of the machine.
This hopper is provided with a sliding adjustable bottom, K, the outer end of which has a pendent nut, j, attached, l through which a screw-rod, L, passes, said rod having a toothed wheel, 7c, u pon it, which gears into a'correspending wheel, l, on a shaft, m, the latter passing horizontally through the lower part of the hopper J, and having a crank, n, on its outer end. The shaft h has its bearings in the upper part of the uprights z' i. This shaft has a toothed wheel, N, at one end of it, which gears into a pinion, o, on the shaft d, and on the opposite end of the shaft h there is a pulley, p, around which the cross-belt g passes. 0n the shaft h there are also keved two pinions, q (1 which gear into two toothed cams, O-O, on the ends of a shaft, P, the latter passing thiiough a bar, Q, to which plungers It R are attached. The ends of the bar Q are fitted and work in oblong vertical slots i' in the uprights z' z', and the cams O O are provided with flanges s s, which work between rollers t, placed two on the shaft It and two on a shaft u, the bearings of which are in the lower parts of the uprights The toothed cams O O are quite irregular in form, as will be seen by referring tog. 1, but they are of the same diameter at all points, and they are placed eccentric'allyl on thev shaft P, as shown in figs. 1 and 3. To each cam'O there is attached a cam, S. These cams, S, are irregular-shaped rims at the inner sides of the cams O, and they work between pins v v, attached to levers T T, the upper'ends of whichare secured by fulcrunipins w to the framing II of the machine. U represent crescent-shaped or bowlevers on the ends of a shaft, V, which passes horizontally through the hopper J, and have cach an arm, W, attached. The lower ends of the arms W have bars X attached to them by pivots, and the outer ends of the barsX are notched to fit over the ends of a bar, Y, which rests on parallel horizontal bars Z Z. This bar, Y, works between the nut j, of the bottom K, and the wheel k, on the screw-rodrL, as shown in fig, I. The lower ends of the leversT T have slots, 1;', made in them to'receive the ends of a shaft, c', which passes through thetsidles d it of a, pox, Af ,underneath the hopper J. This box, A', is open at its top and front and rear ends, and within it there is fitted a plate, B', the rear end of said plato having bars or strips a* attached, which are bent over a shaft, e', in the box, on'which they are allowed to turn or work. 'lhe rear end of the plate- B hasalprojection, f,'extending upwardand backward, as shown in iig. 1, and a plate, C, is securedtransversely upper surfaces of the sides d d of the box, the plate C', when the box A is shoved for-ivard, beingA underneath moulds D, in which the plungers R R work. y
Theoperation is as follows: The clay is introduced into the screen C, and is cut or lreduced by the action of the teeth c onw the revolving shaft F, and drops between the bars of said screen: into the buckets e of the belt I, and is carried upward and discharged into the hopper J.- As the plungers R rise from the moulds D', a result due to the Vtoothed cams O O, working between the rollers t, the bottom K of the 'hopper J, which is partially withdrawnor open, is moved forward'under the action of the curved levers U, which are operated by the hubs of the cams O,- and the front end of the bottom K being` curved or bent down, as shown at 0*, the clay in front of c* is forced into the moulds D. The plungers R- then descend and press the clay in the moulds, the plate C on the box A serving as a bottom 'for the moulds. Where theplungers R reach a certain point, the termination of their pressing movement, the pressure of the plungers is slackened or eased, and the box A is drawn backward, under the action of the levers T T, and the plate C is withdrawn from underneath the'moulds and'the pressed clay or bricks therein, and the plungers R `descend and expel the bricks from the moulds, discharging them upon the .plate B. The box A then returns, the plate C" clearing o" the bottoms of the moulds and the plate Bdiseharging the bricks, the plate tilting as it passes out from underneath the moulds, as shown clearly in iig. 1. As the plungers R make their nal downwardl movement, the lines of the cams O act upon the levers U,Iand thebottom K of the hopper J is movedfback to admit of another-quantity of clay to pass down in front of the bent end c* of the bottom K. The plungers R then rise and the operation is repeated. The quantity of clay fed into the moulds isA regulated by a'rljusting the bottom K'o` the hopper J through the medium of the rod m, pinions llc, screw-rod L, and nut j. l
Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is-
1. The 'sliding box A', provided with the "plate C', in combination with the fixed moulds D and the plungers R, all arranged to operate in the manner substantially as and- 1"or the purpose settorth.
2. The sliding bottom K, operated substantially as shown, in combination with thexed moulds D plungers R, and the plate C on the sliding boxA, substantially as and for the purpose specified.
3. The adjusting of' the bottom. K to regulate the supply'of clay to the moulds through the medium of the `rofl m, pinions Zik, screw-rod L, and nut j, substantially as set forth.
4. The pnlverizing or reducing of the clay by means of the oscillating screen C, and the teeth c on the rotary shaft F, substantially as shown ariddescrbed.
