. IMPROVEMENT- m slr'Ao Letters Patent No. 109,997, dated December i870.

the Schedule term-ea to in these Lottoxi mm and making part or the same.

Be it known that I, J n nes M. Ausrm, of'Georgetown, in the county of Pettis and State of Missouri, have invented a nenf'and improved Brick Machine; and I' do hereby declare that the following is a full, clear, and exact descriptionthereof, which will enable others skilledin the art to make and use the same,- reference being had to the accompanying drawing. forming part of this specification. 7

- This. invention relates to improvements in'briele,

machines, and consists in anarrangement of they mold-carriage. ona pair offlanged rollers at the rear, and a pair of plane -faced rollers at the front,

the latter being connectedbyvertically-sloited plates on the-carriage and pins on the 'sidesof the rollers in such 11' way that the carriage, whiclrismovedin and out by the turning of thesliaft; of the front will be very: accurately, guided bythe said boarrested ,at the proper time by the pins coming against the bottoms of-the slots.

i- Theinvention also consists in the connection of the press-operating devices with thecaM-iage-operatin g dev'ices in such away that the 'risingoi the press at the time of the'outward movement of the carriage will always be insnred. p v The invention also consistsin the application to ''tlie grate, through which the clay is pressed, of dej tacliabie plates, with .holesthrough them for forcing 'the clay throriglnso that plates with larger or'sinallerholes may he used, according to whether the clay is thick Ol' thi|1,-th0 flow of which into the molds varies I Y according to its consistency, which flow it is the oh- 1 jest-of this part of the'invention to regulate.

' -FigureIis a sectional elevation of my improved machine, taken on the line a: :r-of fig. 2.

- Figure 2 is a horizontal section on thi: line 3 3/ of fig; 1, with someparts broken out.

; Figure 3 is a section through thc'gra'te v of reference indicate corresponding :B, theepressywhich may be of ordinary constructhe flanges.

The outer end isarranged on the large plane-faced I, rollers 1*, ,and the slotted flanges are arranged on the earrnige to project downward, one on the outer's'ide of eaehrolllr, snnglyagainstflio said side, and mom a pin, H, projecting from the wheel into the slot, shown in fig. 1.

Thegreater part of the weight of the carriage is borne by-these rollers, and the-motion is imparted by the turning oftho shaft I through the medium of the lever K, r olling thesa'id carriage back and forthmainly by the frictional contact, but the slotted -plates "G and pins H prevent any slipping other.

They also cause the stopping of the oarriage at the ,reqnired plaee, when moved either ivay, by the contact of thepinswith the bottoms of the slots.

The press-follower I is. suspended from theorosshead K workingon the vertical'gnides L, and the said cross-head is connected by the rods M and bar N with the foot-lever O, for forcingthe follower down to v press the elay'thron'gh the grate P, into the mold-boxesl).

, Inorder to insure the risingof thefolloiver at the cnrved'rods R, pivoted to the {lamest S, with the rods Maud-the pins H, as shown, so that the-pins lil'lOlilllg, .l ill(l61'tile 1;ods R, -which; are suitably curved downward for the purpose, raisethemand the follower-during the outwardn ovoment of the carriage.

The 'clay or mud varies" considerably at diii'erent times in consistency; according toftho nat'ure oi the sand and the amount of water 'm'ixed'with it,"so that, with the gratings, of the same size, more clay will be forced into the molds at one time than at another.

I therefoleprovide the main grating Pvwith open-' lngsof the largest size, to be used when the clay is stilf and flowsthe slowest; and -I arrange the said grating-plate'with grooves or channels, in which-I may slide other plates, '1, containing 'smalleropenings, for the clay to be placed on the gratingP when the clay isof the character to run more freely;

--Any number of these plates'l. may be'provided,

the holes being varied in size to suit any condition of the clay; r ,l g

The said plates are inserted through small openings through the front side .of the mold-hex, coinciding with the grooves or channels in plate 1.

Having thus described my invention, I I claim. as new and desire to secure by Letters Patent 1. The combination of the press-follower, the operating wheels 1*. of the cai'i-iage;.pins H, slotted plates K, and connectingaodsM, substantially as G, levers specified. I r

i 2. The combinationwith the niold-box and-press ing oase of the grate-bars or'plate 1!, and the detachable plates '1, the-saidplates having the holes. arranged in the order substantially as specified.
