. l TO ALL WIIOM I'l MAY C'ONCERN:

Be it known that. I, JOHN M. Merian, ot' Pittsburg, in the county of Allegheny, and State of Pennsylvania, have invented a new and improved` Machine for ther Manufacture of Brick; and I do hereby declare the following to be a full, clear, and exact description of 'the construction and operation of the same, reference being had to the annexed drawings, made a part of this specification, in which- Figure 1 is a perspective view, Figure 2 a transverse section, and Figures 3, 4, and 5 sectional views, with letters of reference marked thereon. ,l lhe nature of my invent-ion consists in the arrangement and construction ota `new and improved soft-mud, self-tempering, portable brick machine, of which the following is Aa description of itsia-rrangement, construction, and operation. .7

I construct the mudtub or hopper A which receives the clay of wood, in circular form, `ofany given size, and secure it with bands, with raised metal bowl in the centre, letter K, fig. 3, and place it on the cast-iron bedplate B B, fig. 1, made secure in the raised groove C cast upon the bed-plate, which, with the parallel beam D i D, secures it in place. The beam I) D passes across the centre of the tub, and is held in place by bolts or rods ou the outside ofthe tub, secured to the bed-plate, through the centre ofr which the shaft E passes, with shoulder resting and revolving on a step in the bed-plate, through wl'iiclrthe" shaft passes-to receivepthe spur-whe`el beneath, secured. by a key. The sickle or shear-spuds F, fig/3, through which the shaft E passes, are firmly secured to the sides of the hopper by means of bolts, and-'remain fixed, over and beneath which the knives attached to shaft E set, or, regulated by washers,rcvolvefcutting, crushing, pulverizing, and mixing the clay, which is placed in the hopper together with a stream-fof water, as shown in fig. l; Bymeanslof the sickle or shear-spade F the cut-ting and crushing is consta-'nt and gradual, giving` increased surface and requiringr less l power. The lower knife or sweep II, fig./3,'attachcd to shaft E, is made in curvedor sicklc'fornuwith drag or trail filling the space between the sides' ot`thc hopper and the raised bowl in the centre, (the bowl filling the space to prevent the` sweep from carrying around an undue quantity of tempered clay,) carrying around the mixed clay to 'opening I in the bottom of the tub or bed-plate, and forcing the clay through the opening into plunger-box beneath, shown in fig. 2.' The spur-wheel beneath, :rlitached to shaft E, connects with spurwheel No. 2, fig. 2, joined on the end of power-wheel shaft with double-crank moving pitmen, connecting with cutter L and plunger M, made of cast steel, as shown in fig. 2, with openings in the centre, through which shaft E revolveswhich can or may be driven by cams or ccccntrics attached to shaft E in plunger-box, instead 'of double crank and pitmcn. The cutter L Vpasses before plunger M, severing fthe clay between opening I and uplungerbo.\', covering opening I, preventing the return ot' thc clay into hopper A when plunger M forces the clay from thc open end of plunger-box into the moulds in place in large brick-wheel. llunger M is regulated by means of an adjustable bur on pitmen, so as to admit arequisite amount of clay Ainto plunger-box and no more, to be forced out, and upon withdrawal forming a. vacuum und causing a suction, thus aiding the knife or sweep H in refilling the box, the knife L working backward and forward in advance of plunger M. Theplarge metal brick-wheel N, fig. I,I construct of any given size, with shaft passing through `the centre, resting upon arms of the bed-plate, te which it is secured by boxing, and provided with the slots 0 0 at equal distances, with grooves on both sides of the buse to receive and keep in place the brick-moulds, which arc provided with slides.I The wire P attached to the side of the wheel at the end of the slots O O prevents the moulds from passing beyond their` places, and is so arranged as to leave an opening for the removal of loose sand or dirt at the buse of the slot. The wheel N is provided with cogs upon the rim, by which, at regular intervals, it is drive'n by a one-fourth cog-whecl connecting with power "beneatln The brick-moulds being placed in thc slots O O, are carried around, by thc revolution of wheel N, to the open end of plunger-bor, when and` where they are filled in turn bythe action of plunger M, and when filled, while in pressure, before the withdrawal of the plunger, the knife Q, fig. 1, passes down betweenfthe mouth ofthe brick-mould andthe end .of plunger, cutting ofi' the clay smooth on the top of the mould, and acting as a covering for the mould, keeping the clay` in place until the withdrawal of the plunger, when the knife Q rises and wheel N revolves, acting as an olf-bearer, carrying the moulds thus filled up, Vevery second revolution of .the enefourth cog-wheel, to a level, when the mould is forced out from the slot on to .'t table, by means of the arm R- pnssng through the slet, which is u pci-rt of shaft S extending above and parallel with beam D D, upon which it rests by Ineens of uprights; the shaft S connecting with shaft E by menus of pinion-wheels R R,Whieh give' it power. On shaft S, place n. one-fourth cam, T, which :Lets in und upon the stop-cem frame U, which is attached by :trod to knife Q, causing it to rise and fall when shaft S revolves, cutting away all excess of clay from the moulds, which is retained in plungerbox. I construct the mould W ofsteel, (see figs. 4 und 5,) with slides to enter the grooves in slots O O, of the size of two or more bricks, the bottom swinging upon hinge which forms one of the slides, the other bein-g riveted to the opposite side. When the mould is full and upon the table, thefbrick is removed by inverting the mould and lifting the leaf or bottom, admitting the air, when the mould is readily removed from the brick, then sanded and replaced in the slot`0 of wheel N before it descends.

Whut I claim ns my invention, and desire to secure by Letters Potent, :1re-

The sickleror shenr-spuds F and lower knife or drag H in hopper A, in combination with the raised bowl,A constructed, arranged,Y and operated in manner set forth. Y Y

I claim the knife L and plunger M, constructed and applied in manner und form substantially as described.

I claim the briel -wl1eel N, with slots and grooves to admit moulds, operated substantially as set forth.

claim the arrangement of the stop-cam U in connection with knife Q mdnrm RQ arranged und operating in manner described.

claim the mould with hinged buse, constructed und used as described to and for the purpose intended.

n testimony whereof I, the said JOHN M. MOYER, have hereunto set my hond.
