Specification ofiLettersPatent? No. 1,539, dated April 8, 1840.'`

`and`v useful Improvement in Machines for Making Bricks from Dry Clay, which is described"l as follows, reference beinghad to the annexed drawings oft-hesame, mak-ing part of'this specification.

Figure 1 is an isometrical perspectiveview1v ofthe machine. Fig. 2' is a vertical section through the centerv of the molding.

part of the machine showing the molds, the discharger, presser,.connecting rods, guides', &c. Fig. 3 is a top view of thetable.-

Similarletters in thefigures refer to similar parts.

`A frame or-bench A isA made of suitable size and strength to contain and support' the parts hereafter described. Upon v this frame at one end is secured av large cast iron plate B let into the frame from which rise two standards B1 B2 between which the main or pressing lever H is placed, the fulcrum being at 00. This plate may for the sake of distinction be called the stand. The molds are secured on this stand. They are formed iso by two vertical parallel side plates l, 2 flanged at their lower edges and perforated for bolts which secure them to the stand B, between which side plates are division plates C1 C2 which form the molds. A table Gr is formed on a level with the top of the molds having rectangular openings Y therein the size of the molds and two ribs W at the sides of the table which serve as guides for the sliding feeding boX A piston for pressing the clay into the molds is attached by connecting rods to the short end of the main lever H. This piston consists of a plate E having fixed to its under side as 'many rectangular blocks b as there are molds made the same size as the molds into which they are intended to enter, during the operation )of pressing the clay- An ear e projects from the upper side of the plate E through which.

passes a horizontal pin which also passes through the lower ends oftwo parallel connecting rods R connected to the short end of the main lever by'a similar pin passing horizo-ntally through the same- A vertical rod V1 rises from the top of the ear in the center of the plate E and passes through an aperture in a horizontal guide 3 fastened to one of the standards B2- A similar rod V2 rises from the plate E passing through a short tothe level ofthe table'.

side of said'plateD'there projects downward:

horizontal guide t; these rods and guides are for causing the piston to movevertically in the molds.

The discharger for throwing up the bricks from the molds is attached to the short end ofthe-lever Lby a connecting rod Si This dischargerA consists of' a horizontal' plate D upon whose upper side are placed' as many rectangular blocks T as there are molds-into which they enter being the same size and while the pressing` operation is performing theseform thebottom of said molds the plate resting'firmly upon the' standy and when the bricks are to be discharged these blocksl are made torisein the molds and lift the'bricks a vertical stem Z the round part" of which. passing'accurately'through a roundt opening.

in the stand andserving as a` guide to*l cause thev discharger to move correctly' in the' From the under molds; to this stem the rod S is connected which attaches the discharger to the leverY L which moves it-which lever has its fulcrum at M below the top of the frame or` forms the double operation of conveying the clay to the molds and at the same time pushing the bricks from them to the end of the table. This boX is attached to a lever N, O, made inthe following manner: It consists of two arms or branches N, O, radiating from the periphery of a barrel 5 to which they are permanently fixed, which barrel turns on a permanent stud P rising vertically from a casting 6 fastened to the top of the frame near the center thereof. The branch O of the lever acted on by the cams Q g is made forked so that the prongs shall be acted on alternately by the cams on either side of the wheel Q2 as it revolves for moving the boX F in and out from under the piston. The cams for moving all the levers are fixed on the main shaft I which turn in standards 10 fastened on top of the frame which shaft is turned by any suitable power the cam marked J moves the main lever H for pressing the bricks-the cam marked K moves the lever L for discharging themand the cams marked' Q g move the forked lever N, O, for supplying the clay and removing .the bricks fromv the molds.

Operation: The power being applied to it into the molds and thus forms the bricksfthe piston and discharger then rise simul-` taneously the latter pushing the bricks out of the molds from which they are removed by the sliding box inl bringing afresh supply of clay to the molds. When the cam J is in the position represented in the drawing the pressing has commenced and when the greatest extremity of it marked 7 reaches the anti friction roller in the end Vof the main lever Hthen will take place the maximum of pressure-this part of the cam having left the roller the long end of the lever Will begin to descend and simultaneously with this movement the cam K-Will commence to depress the long end of the lever L- and raise the short end With the dischargers and also at the same time the cam Q will begin to vact on the prong 8 of the lever O causing the box F to move toward,

the molds-WithA a fresh supply of clay which it deposits in the molds and the `cam `Q having left the prong 8 the other cam g on the opposite side of the Wheel Q2 strikes the prong 9 and reverses the movement of the lever bringing back the box F Vemptythe cam J then acts on themain lever as before and presses the bricks and so on. The bricksare borne o' by boys or in any convenient manner.

What I claim as my invention and desire to secure by Letters Patent is- 1. The mode of producing the pressure on the piston E by means of the lever H operated by the ca m J in combination with the mode of operating the bed D of the press fory throwing up the bricks when pressed by means of thelever L operated Y by the cam K-t-he Whole being constructed, arranged and voperating as herein set forth.

2. I also claim in combination With the foregoing the mode of operating the box F and removing the bricks by the same, the box being operated bythe forked lever O moved by the cams g VQ all as herein set forth.
