TO WHOM IT MAY CONCERN: l

Be it known that Ponsen L, Swonn und Gnonos S. TIFFANY, of Adrian, in the county of Lenawee, und State of Michigan, invented e new and useful Improved Brick Machine; and I do hereby declare that the following is a. full, clear, and exact desoriptionof the same, reference being had to the annexed drawings, making part of this specification, .in whichy Figure 1 is an elevation, showing the side of the machine fromwhieh the completed bricks are removed.

Figure 2 is an elevation, showing the side of the.ma.chineon which the bricks are formed.

Figure -3 is a plan of the partsvbelow the mould-wheel.

Figure 4 is a part of a. vertical section through the line a: z z in lig. 5.

Figure 5 is a horizontal section through line y y, iig. 2. I

A is the pug-mill, for preparing and feeding the clay to the moulds. A set of knives are arranged-upon the vertical shaft Af, to which the power is communicated in any convenient manner. The knives or paddles A" have their faces so inclined-aste work the clay downwards, the lower onesrunning' in close proximity to the bottom formed by the bed-plate l),and presenting to the Opening therein a face so inclined as to press the clayinto the mould, which rvolv'es immediately below the bed-plate. The spur-wheel A on the pug-mill shaft A drives the spur-wheel B on the shaft B, which passes through the' bed-plate D, is attachedv to and turns the mouldqvhcel C. The mould-wheel is a heavy cust-iron wheel, made thick enough at the rim to permit openings to be formed vertically through it of the-size of a'briok.' These rectangular Openings are formed 1n succession around the entire rim., and in each is 'ttedneatly a follower, F, having a stem, F1, projecting downward through guide plates F2 fastened to the solid portions of the rim of the wheel. A flange, C', projects from the periphery of the wheel a little distance below its upper edge. The bed-plate D is a heavy plate of cast iron, resting upon suitable supports, which carries the entire mechanism. It covers the ventire mould-wheel except where cut awajgjupon the sides to show the rim of the wheel. The vend D2 opposite the pug-mill ie raised, as shown in fig. 1, for purposes which will be explained. The cylinder of the pug-mill A' rests upon a band, A, which maybe cust separately from and bolted to the Abed-plate, or'it may be cast as u part thereof. A curved opening -is formed in the bed-plate under the pug-mill and immediately-above-the line of moulds in the rimof the mouldd i.

wheels. The curve of this-opening is an arc of a circle of the same radius as that'of the mould-wheel. From this opening, and upon the same curve,extends a tubular aperture, DL, over the line of moulds, and in it is placed a plate, E, hingdat the top ythereof nearest thc png-mill, and inclined so as to bear upon or in very close-proximity to the upper face of their-rim of thenpould-wheel, the endlbearing against the adjusting A'sete screw E', by which its position is regulated. -As the clay is pressed'down by the paddles A3,' it will heforeedl into the moulds, and also fill Athe spuce'betwcen the mould-wheel and the adjustable press-plate E; the action olIl the revolving wheel will' closely nolnpressthe clay between it andthe inclined 'press-plate, and ll thereby the moulds as they successively pass under the curved opening and tubular extension` thereof. G is a wheel, tui-nf ing freely upop the shaft G1, oneA end of which isfastened to the central block L, and the Other'to avertieal rod, G, passing through the bed-plate D, vand havingon the upper end a. nut', by which it may be raised or low-I ered for the adjustment Of the height of the wheel D. As the mould-wheel revolves. the ends of the stems F of the follower F will be successively brought against the upper part of the wheel G, and, in lpassing upwards i over tl'eisnmo, force up the followers and compress the clay in the moulds against the press-plate E. After the moulds ure thus filled, they pass from under the press-plute, and the clay projecting from their upper surface is shaved olf by the edge of the adjustnbleknife K, secured to the bed-plate by a set-screw passing through u. slot in the rvertical flange to which the lhorizontal plate, forming the knife, is attached. After the mouldsl have passed under the'knfe, the stem Fof the followers will Vstrike against an inclined plane, M, resting upon suitable supports, bywhieh the followers will be forced upwards, lifting the bricks out ofthe moulds, under he raised portion D2 of tlie'becbplatc, which is here carried up for the purpose. Whcnthe bricks have been lifted from the moulds, as they pass the part ofthe bed-plate cut away on the side of ythe machine, they are to be lifted oif and carried away. The portieri of the way M under this part of the wheel is horizontal, and it begins to decline immediately'aftel" passing this part, so that, when thebrick has been removed, the followerl tney full as it passes under the pug-mill, opening the mould for tho reception of the clay again. The shaft B and the mould-wheel C are carried upon wheels H, which are placed under the' nnge C. These .wheels turn freely upon 'shafts Hl, wbibpre sustained at one end upon bearings in the block L, sind at the outer end by the rods Hpassig through thebed-plate, andsuspended by nuts H3, `for the purpose of adjusting them to the wheel. Toprevkent any lateral motion in the mould-whee1 C, an .adjustable guide-plate, I, is attached to the under side of the bed-plate, bysets of screws passing through slots in the guide-plate, so lasi'to permit the latter to be kept iu contact with, or in 'very close proximity to,lthe .periphery of the mouldwheel immediatolyvover the flange C.r A convex Plate, I, is in like manner attached to the bed-plate within the rim of the mould-wheel.

What I claim, and desire to secure by Letters Patent, is-L 1. Adjujtably-suspending the mouldfwheel C from-` tbe bed-plateupon wheels I-I, upon which yit: revolves substantially as set forth.

2. The combination of the mould-wheel C, and pug-mill vwith a. bed-plate, C, having a curved lineal opening under the pug-mill and over the moulds, substantially as described. 8. .A curved tubular extension, D1, lending from the bottom of thepug-mill, over the rim of the mouldwheel, thiough'whch the clay is fed 'to the moulds','substantially as set `forth.

' 4. The inclined adjustable press-plate E, placed-in the tubular extensionD, in combination'withl the mould-wheel C. 'A l A Y .Y

5. 'The combination of the press-plate E, mould-wheel C, followers F, and wheel G, substantially as and for the purpose set forth. v

6. Adjuitably suspending thc whecl'G from the bed-plate D by rods G', substantially.' as and for the purpose set forth.l

f 7. The combination of the uiould-wbeel C, bed;plnte D, and the adjustable packing rings I and I attachedv thereto, substantially 'asset forth.

8. The combinationl of the adjustable press-plate E, and adjustable knife K, having a horizontal blade,

substantially as set forth. n l

In testimony-whereof I have signed'my; name toy this specification before two subscribing witnesses.
