llc it known that l, Purple H. KELLS, of Adi-inn, in the county of Lenawee, und Stute of Michigan, inne invented :t new nml improved Bi'i :i;-\Iucliine; und I flo hereby7 declare the following` to be nfull, clear, und exact description ot' the sume, sufiicient to cnnble one skilled in the nrt to which the invention uppertuins to make use of il, reference being html to the accompanying drawings, forming o. port of thespcciiieution, nntl in which- Figure l. is n' top view, partly in section.

Figure il is r. sectional elevation. y

Figure is n rcrticnl section through one of the pug-mills, the line zvrc, lig. l, indicating the plane of section.

Figure -l is e vcrticol -Section on the liuc y y, iig. l. l

Similar lettersef reference indicate corresponding parts in the several figures.

'lhe clay is ground in` two pugnnills, und pressed into moulds on opposite portions of the uppei side of a. bed or wheel rotating on n. vertical nxis, which is uliorzlccl by u central hub upon which the mould-wheel rests. The untold-wheel is :ilse supported by carrier-wheels. The clay is pressed into the moulds by the blades ofthe pugnuill shafts, und the superlluity is removed, leaving,r the upper surfucelcf the brick smooth, by the pussagcpf the inouhl under n wedge shaped eut-off. lhc bricks ure raised und discharged from the moulds'bv followers moved from below hy the pnssngn of their cnrrinr-r-lmcls up un inclined plne ou the boil-track- In the.drnwings, A A is u frame, haring un unnulnr mould-bed, B, which is supported by u. central hub, C, und carrier-wheels l), us it. rotates beneath the pug-mills E E, which occupy positions at opposite portions ofthe upper siile of the mould-bell. The motions of' the various parts nre derived from the main shaft; F, whose bevelpinions G rotute the wheels ll Il I l. The wheels Il II rotate the shafts Kl Kl, "which carry at their lower ends the rotating pinions K K, which engage or lgem' with the cogged periphery of the mould-wheel Bythrough the medium of the intermediate pinions K2 K2, snid 'inould'wheel thus receiving n. sleucly rotary motion by power applied :it its opposite sides. '.lhe bcrel-cogs l l imfmrt n rotary motion to the vertical central shuftsJJ of the pug-mills. '.l`he pug-mills are supplietlvfith clay, which is tempered therein by the rndiul arms Jl J1, und forced therefrom bythe ohliqhe' blades Ji Ji, which project from the shefts l J, The oblique blades J2 press the clay through the throat (l into the moulds e, in which it is solidly pticlieil` As the mouidvbetlrotntcsftho moulds ure brought uiulcr the wedge-shaped piece d, the sharp cdgcol' which shores oil all the clay not in the moulds, und smooths the moulded clay on its upper surface. The pug-mills nre supported upon bridge-picces or be lplates h h; which rest upon the centi-ul hub C und the ironie A. '.lhe brick, haring pussed from beneath the pugqnill, is ejected from the mould hy the raising ci' the follower m, which forms the bottom of the mould. This is aecomplished by efmsingl the carrier n, which supports the follower, to risc on the incline p, and thrust the followfer up .even with ,.hc surface of the mould-bed, when thc brick is removed by tho attendant. If desired, the gearing may he so urrnngcd :is to rotate the mould-wheel and the png-mill shafts in the same direction. A

llnving ricseriteil my invention, what I cluiin therein as new, und dcsireto secure by Letters Patent, is-' l. 'llw romhinntion of the annular moulthherl B, and the central hub or support C, substantially as described und represented.

2. 'the adjustable wedge-shaped cut-olf d, arranged-und employed in the manner and for tho purpose explained. Y v

3. The errati-ement upon thc mouhl-wheel ot the two pug-mills on opposite portions, substantially as described.

4. An :tnuulur mould-wheel, provided with cogs or geur-teeth upon its periphery, und mounted upon u central hub or support, substantially us und for tho purpose set forth. l

To the above spceilicntion of my improved brick-machine, I have signetlmy hond, this dey of PHILIP H. KELLS.
