UNITED STATES PATENT oEErcE'f 14 STEPHEN USTICK, OF PHILADELPHIA,PENNSYLVANIA.

BRICK-nonnina MACHINE.

Specification of Letters Patent'No. 5,187, dated Tuly 10, 1847.

To all whom t may concern.'

Be it known that I, STEPHEN USTICK, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Machines for the Manufacture of Brick, and thatthe following is a full, clear, and exact descrip-V tion of the principle or character which'distinguishes them from all other things before known and of the manner of making, constructing, and using the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1` is a plan of the machine; Fig. 2, a. view of the underside; Fig. 3, a side elevation; Fig. t, mold and parts detached, and Figs. 5 and 6 modifications of the machine.

The same letters indicate like parts in all the figures.

The nature of my invention consists in an apparatus for molding dry clay, which is pulverized and sifted for that purpose.

It consists of the following parts: first, a pulverizer into which the clay is received from the bank; this pulverizer is an inclined revolving shaft (a) surrounded-by a cylinder that turns in an opposite direction, the upper end of this shaft within the cylinder is armed with projecting pins that mesh in between similar pinsV standing out readily from the insidev of the cylinder; as this is similar in construction to many other machines for like purposes the interior is not shown. The clay after passing down through the cylinder past the pins Vtothe lower end is then sifted through perforations (b) made in the cylinder for that purpose and is caught on an apron or hopper (c) under it which conveys the clay into the circular hopper that supplies the molds.

The large pebbles and coarse clay being car` ried out of the end of the cylinder into a trough down which it runs out of the ma.

chine. The outer cylinder (b) is turned by a band (CZ) from a pulley on a shaft (e) above; on the same shaft there is a spur wheel (f) that gears into a pinion (7L) on shaft (a) by which it is turned in a direction contrary to the surrounding cylinder. rlhe short shaftv (e) receives its motion from the driving shaft (g) through the spur wheel (i) and pinion (7c). The clay is dried by means of a hot air tube that enters the shaft (a) at (a), or by surrounding the outer cylin-V der with a furnace if required. The hopper (Z kinto which the clay is received from the pulverizer is of annular form and is at-V tached to a horizontal wheel that is'made to revolve by means of t-he bevel gearing (m) and (a), that connects it with-the driving shaft (g) which are within the hopper while j,

the wheel (Z) is extended out some distance beyond it. This wheel turns on a stout center stud firmly fixed in the stationary frame thatpartly surrounds the wheel to which several cams hereafter described arefv i also attached beneath the wheel for moving,

the different pistons, belonging to the molds that are connected with the wheel, as they revolve. in the'bottom of the annular hopper (Z), they .are lettered (0), beneath which the molds are situated. These molds (see Fig. t) consist of a box (p) below which there is a frame (g), for the pistons to Vslide in horizontally which extends out a little in front, and from this frame the shanks of two pistons project radiallyq one of which (r) I denominatethe inner piston is toward the axle of the wheel and forms the side of the press on that side, the other Y(s) projects toward the periphery of the wheel and forms the opposite side of the'l press: between these the clay is consolidated. The underside of each of the pistons is furnished with a small stud roller (u) and ontheir extreme outer ends they have broad friction rollers (u), the `former work in light'V grooves to regulate the motion of the pistons when not pressing; the others come in contactwith permanent cams aty the proper When i i the mold arrives at thepoint (o) where it v is to receive its charge of clay both of the pistons are spread apart so as to leave an open space from the box (29) down between E them; they are brought to this position by j.

means of the cam grooves in which the stud rollers (u) above named run; these cam grooves (w) are adjustable andtheir distance apart is regulated by a radialV screw which determines the quantity of clay that shall be filled into the mold, by causing the pistonsto approach or recedeA from each other as they are adjusted. When i'illed the mold moves on as the wheel turnsy in the '10 The openings into the molds are Y outside the mold.

(y) bears against the friction roller on the end of the piston rod (r) while this inner piston is thrust forward the outer one is allowed to recede a little by the form of the cam groove (fw), which guides it, till the clay between the pistons, which is to form the brick, is thrust outward far enough to carry it beyond the boX (7J) into the space where it is pressed, the outer piston then stops and resists the pressure of the inner one which is still borne forward by the cam (y) till a certain amount of pressure isV produced on the brick, the cam then become concentric with Vthe wheel so as to keep the piston (r) stationary in the mold'` and then the outer piston (s) isforced inward by an outer stationary cam (e) till the brick is suiiiciently pressed. The stud wheels on the pistons are then acted on by stationary guides orV cams (y) and (e) which move both pistons out carrying the brick with them under a `vertical piston (s) placed at right angles to them in a frame in the wheel When the face Vof the outer piston has advanced to the outside of the mold, by a suitable form of the cam groove (w) in which the stud roller of the piston works, the piston is moved more rapidly than the inner one to remove it entirely from the brick. When the brick is thus pushed out of the mold the horizontal wheel (Z) has revolved far enough to bring the upper end of the rod of piston (3') into contact'with a stationary cam (15') attached to the frame above, see Fig. 3, this forces the piston (s) `down and discharges the brick below, whence it can be carried olf by an endless apron or other convenient device;

and the pistons are by their guides brought into the first position for receiving clay. A series of any number of molds may be put into the wheel which follow each other consecutively through all of the above described positions, being supplied with clay at the point (v) and discharging the brick at the cam (t). The frame can be made of any 'w and 6.

suitable material and should be suiciently bracedV to Vresist the pressure upon the stationary cams attached thereto; this is shown inthe drawings and designated by letters (A` A) but these parts are not described, as they may be indefinitely changed to suit the views of the manufacturer or purchaser.

Many parts of my machine can be modified, an example of which I give in Figs. In these figures corresponding parts .or those which are substituted for others in the main description bear the same letters:` the. most essential change is in the cam (z) for pressing` in the outer piston l (s), this has a little carriage running on two horizontal wheels (11') with flanches on them Vthat fit on and are guided by said cam (z) this carriage is kept in place and guided by a third wheel that is also horizontal and grooved, this fits a rail (Z) parallel with cam,(z), the end of the outer piston (s) as it comes 4around to this carriage strikes 1t andcarries 1t around the length.

of the cam where it is disengaged; Fi'g. 5 shows the piston and carriage in contact. When disengaged the carriage is drawn back. by a cord and weight over proper pulleys.

Having thus fully described my machine, what I claim'therein as new and desire to secure by Letters Patent is- 1. The combination of the pistons with the camsin the manner described, said cams y being adjustable and guiding the pistons during the whole revolution of the wheel substantially as herein set forth.

Y 2. I claim the combination of the revolving screen and pulverizer with the horizontal wheel of molds, constructed substantially as hereinbefore described.

3. And lastly, I claim in combination withithe double piston mold the apparatus for discharging the brick from the mold Y,

andvcleaning the face of the pistons consisting of the vertical piston and cam arranged as described.
