iMPRovEMsNT N BRICK-MACHINES.

.To all whoin it 'may concern.' l Be it known that we, BENJAMIN M. GARD, ofUrbaila, in the county of Champaign and State of Ohio,

andEMERY R..`GAnD,vof Chicago, in the county of (look and State of j1llinois l 1 ave invented Improvements iu Machines for Molding and Pressing Bricks and we do hereby .declarethat the following is a full and exact'description theieofreference beinghadto the accompanying drawing making part of this specilication'- Figure 1 being a side elevation of a brick-maohine provided with our several improvements.

- Figure 2, a rear elevation of the same.

I Figure65a horizontal section thereof, ina plane indicated by the line y y, figs. 1 and 2 Figure 7, a vertical section of a `part, as indicated by the linee/@tig 6. I Like letters designate corresponding parts in all of the figures.

The general construction vand operation of the ma chine to which the present improvements are applied, as repres'entedin the accompanying drawing, are the same as in the brick-machine. for which Letters Patent of thefUnited States were granted to us on the 22d day of February, 187 0;V but We do not intend to `restrict the .use of these improvements, so far as they may be applicable to other brickfmachines, to a machine of that construction.

Thus the machine to' which we have applied our improvements, as represented inthe drawing, has itsworkng parts, comprising its mold-wheel H, feedingscrew l, and mixing-arms J J, arranged and secured upon a single driving-shaft, 1),.and-its principal stationary functional parts, comprising thetub`bottom B,

'trib O, and cam-track E, also4 arranged 'around the same shaft as compactly as practicable.

' The first-feature of our present improvements lies` in the formation ofthe frame-work of themachin'e. The frame proper A consists of side nprights 'a c; connected by a skeleton of brace-bars, b '11, at the base,

the whole'being a single casting, of a form suitable for.

supporting. the several parts. of the machine.

As an additional part-of the frame-work 'or support of the machine,- t-he tub-bottomB has lateral anches ."c c .extending outward'and resting on the tops of Ythe side nprights a 'd vof the`-f1ame A, being securedby `set-screws dll soas to beadjustable thereon, tolevel thesaid bottom and -to trim'ittol theother vparte. of

the machine.

. l Also,:npon this tubebottomvthetub C is vinount'cd, one sideor half, f, thereof being rmly bolted orotherwise secured thereto; 'and the said fixed partis braced at-thetop with' cross-bars g g, -to support thc .npper bearing h of the driving-shaft D of" the machine.

rlhus the frame .proper is lof the simplest,"eheapes t, and mostcoxnpact construction, not encumbering' the upper part of the machine; and two functional parts of the machine are made to do the additional duty of support to other 'par-ts, effecting thereby further simplicity and economy of construction.

'lhev tub .C being th'ns required. to assist inthe sup-l borto'f the operative parts ofthe machine, provisionl is made for getting access to the inside,v thereof, for tnypurpOSe, by hinging'the h alt s ide or part' i, which is not attached to the tub-bottom below, tothe fixed half or part f at one edge, nsgshown in fig-1', so .that it may swing away from-the said .ixedparlg like a' door. l

.The free edge is fastened to theiixedypartby any suitable means.

This swinging part may have a' brace-bar, j, figs. 3

and 4, extending across from edge to edge,- with'a' curved portion in the middle, to it partially around the driving-shaft, and lassist. in supporting or'steady ing the said shaft, as rfell as also to prevent the turning ofthe clay in the tub.

It also may'have aflaring mouth or hopper, lato afford ample room for the introduction.of-the clay or. composition to be molded.

"When the machine is drivenbyanimab power, the same is applied through a'sweep, K, directlyto the` drivingfsha'ft D. If,howev'er, the machine is to'bedriven by `steam o r other stationary power itls mostconvcnie'ntto communicate the motion. tliroughashaft, G, mounted in one side of the frame, andby! a cog-wheel, l', theref.. on, gearing into a set ofcogs, -m, on thelperiphery of the mold-wheel I-I.-

For convenience iii-adapting the machine to"`all s`il; nations, it vmay be .permanently 'p rovidedwi-tl1 vbothvof thesel means of dexjivingits Incisioni Another important featurefofour invention-consists Ain the improveddevice for automaticallyremoving the? bricks from the mold-wheel -successivelyfas.tast as' formed and pressed.' f

- The movements for this purpose'are all derivedfroin' the mold-wheel, which, iu this .fu nctio1'1f,performsthe additionalduty of akdrivigvpulleyor;Wheel.` Thus the lower part of'themoldfwlieeh receives a driving-belga, -which also passesfaround a pulley,.o, Ona transmitting-shaft, L, mounted in a sitablepositionin the-frame'.. A I Ou this .transmitting shaft` is .'another p1- 1lley,. 11,

frolnfwhich belt, q', passes toa pulleyon aborizone tal-shaft, nin' `the outer` end of' the'att-achedfr'ame on which is-mounted the carrien-b'elt Othat comA veys the bricks from the mold-wheel, theinner return of the said carrier belt being around a small roller close to the .upper edge of the periphery of the molduheel. In this'manner the movements for conveying off the bricks from themold-wheel are obtained.

But the essential part of this feature of our invention is the means employed for automatically transfen'ing the bricks from the mold-wheel t'o the carrier-fv belt O.

To accomplish this we combine the actions of two motions, one ,of the revolution of the mold-wheel itself, and the lother that of 'a vertical belt,'P, which has a traverse movement over the mold-wheel in the open space beneath the raisedlside of the tub' bottom B, in a ldiagonal direction, or oblique, between a radial and a tangential direction It passes round a pulley, s,'on the transmittingshaft L, from which it derives its motion, and atits yinner'turnaround a fiietionfpulley, hung beneath `the tub bottom.` v

In its outward 'traverse the belt passes alongside of a stationary plate or board, t, which prevents its yieldinglaterally, as the bricks"are pressed against it.

Themolds Q Q of the mold-wheel haveltwo peculiarities forthe purpose in view rst, they are located diagonally or obliquely both to radialand. tangential directions of the moldwheel, as shown clearly in fig; 5, the forward ends thereof', iu respect to the'motion of the mold-Wheel, being nearest to the periphery of the same, so .that as the molds are brought round under the traverse belt Pthe,bricks, then raised `from the molds, but lying directly over them, will come laterally in contact and-nearly parallel wit-h thebelt; second, the molds are arranged to form the bricks vertically edgewise therein, that is, with the thin sides or edges up and down, sol that as they'are; raised out ofi-the molds'and are brought around against the traverse belt P, their-,broad sides willcome in contact therewith and afford more frictional surface thereby;Av

orthey may come out flatw-ise.A

'lhe result'of the combinedv motions of the moldwheel and traverse belt, withzthis arrangement ofv parts, is to slide 'the bricks as Vthey are brought successively to the belt, eudwise outward, as .indicated by dotted lilies inig. 5,A upon the carrier-belt O, which is located in line with the 'bricks as they are thus moved', and iiush with the upper surface of the mold-wheel.

The bricks thus conveyed iu .an edgewise'position bn the carrier-belt, are also more readily seized and lifted from ythe belt by the attendants.-

The formation of rrthe bricks in vertically-edgewise molds QQ', also has anvadvantage irrespective of` the y purpose of conveying the bricks automatically from the machine; for, by this formal-ion, the thickness of the bricks is always' uniform, which is always of the most importance, while the width only is subject to variationpin pressing them in the molds, a mat-ter oi' less consequence.'

Ilhe cam-track E, on which the mold-followers travel, has one or two removable sections u u, resting in recesses, or between anges c fu, of the track, in the ,portion where the pressure is given to the molded lbricks under the striking and pressingplate R, so as to be replaceable vwhenworn too much; and under one or each of these removable portions is an adjusting screw, w, arranged as shown iu iig. 7, or in an equivalent manner7 for adjusting the height thereof, to compensate for the wear 'ci' the track, and to adj ust the amount ofcompressiomor the thickness or width of the bricks, as desired. Only one end of the track section need be thus adjustable; v 4

Itbeiug necessary either to adj ust the tub-bottom B to the-inold-wheel H,'or the moldwheel to the tubbottem, in order th'at'the former may turn closely by the lower surface of the latter, we eli'ect this purpose Vby adjusting the height of the driving-shaft D, on

which theP mold-wheel is accurately secured.` v

lo accomplish this adjustment a screw, e, is set inA thebotto'm of the lower bearing S of the shaft, asv shownin fig. 3, thc shaft resting on the screw or upon an intermediate step or block.

Vhat we claim as our invention, Vand desire to sc cnre by Letters latent, is

1. The combination of the frameA,.composed of Vthe uprights a n, and connecting braces b b, with the vvbricks from the mold-wheel, substantially as herein specified. .l 1 BENJAMIN M. GARD.
