specification, in which- Figure l is a side elevation of-the pug mill and molding machine; Flg. 2 1s a plan of the frame .and ycarriage of the molding machine; Fig. 3 is a sectional elevation.; and Fig. L is 'a front view. Y
, The same letters indicate like lparts in all the figures.l
The nature of my inventionconsists in a 1 I A' peculiar v construction of machinery to be worked by'hand and horse power for producing in'an expeditious and. eflicient manner, bricks, tiles and other .articles from clay to the molds.
y. In the accompanying drawings A) is the pug mill set on brick work (B, B); ,at
'the bottom of .thejmill is .a metal step (a) in which a vertical 'shaft (b) works. This shaft is supported at its upper end Around .the shaft (b) a number lof horizontal 'cutters -or lknives (c, 0, 0)* are .setj radially; theinner ends of the knives are.
chamfered olf .so that vthe ends of two opposite knives may enterthe samesocket as shown by the dottedlines (0') Fig. 3,; when l thus arranged they Aare secured in their proper position by clenching as shown in the` At .the lower vsectional :elevations at (0.2.). end of the shaft (b) are four radial plates (al. fl) extending horizontally from the shaft each pair `crossing vthe other'at right angles.'
-'the chamber of the molding machine; vtheir facesare setobliquely .to "the shaft as `shown'at Fig. 3, f(rZj)lf(D`) lis the chambery The molding i 'by .a `g .framing attached :to .the top lof jthemill .and is furnished with a lever to vwhich 'horse power is applied .for 'turning the same..
which receives the clay or other plastic material from the pug mill and forthis purpose iits close over the opening (c) as will be hereafter described. The sides .of the chamber are formed by two iron plates (f, f.)
boltedV to a strong frame (E, which supy po-rts the various parts .of the moldin machine. The shape of these plates will `be, best seen by referring to the elevation Fig. l. (g, g) is acast iron grating connected to the side plates (f, f) and .forms the bottom l.
of thechamber (D), Fig. 3. The constructionof this grating consists of arectangular frame withcross bars` or divisions equal yin number to the bricks or tiles to be produced at one working, lor rather with the number ofecompartments in the molds which `are succssively placed beneath it. (la.) ,is ahorizontal shaft which has its bearings in the side plates (f, f), Fig. 4, and -is intended to carry the quadrant `brackets which are ,v e,
each provided with a segment rack; The shaft (71,)l also forms the fulcrum of peculiarly formed pressing plate (7a," la) which,l extends the whole width of lthe chamber (D.)
land forms a partial covering thereto. This.
plate is intended yto rise and *fall vin ,order to .force the clay in the` chamber (D.) :through thel grating into 'the molds, but it will' as to cause .it to break. To prevent the'escape of .clay over the pressing plate a segment .piece is provided which will be in close it two pinions (m, m) are mounted,fthese pinions gear into the segment racks on the brackets (i, i), and are actuatedfby a Ahand lever keyed on the same shaft; (0) .is a rod which passes through lugs or ears on the vquadrantbrackets (t, i) and the rpressing plate (7.5) and isintended to attachthem together in order that theirV movements (when the pinion wheels (m, m) are caused to revolve) Vmay be simultaneous these rsegments are connected with the pressing plate as. far back as possible, so that the .fullpmotion can be ygiven tothe said plate withoutmakingslits in the side plates, as has been heretofore customary by simply cutting out 'the plates (f) on the back edge, by which'I dispense with the slides used in my 4former press without leaving openin s forthe escape of the clay at the sides p) i's a board f secured to the plates (ff) and is intended to cover the opening between the presser plate (lc) and the side of the pug mill (20') is a rod having its bearings in the plate (f, and serves to carry the scraper .(s), which extends the whole width of the chamber (D), and is for the purpose of cleaning oif the clay from the segmental portion of the pressing plateV (7c) at certain Vperiods of the operations of the machine. The rod (p) also supports the catches or hooks (y) which hook into a staple in the pug mill and thus hold the chamber (D) firmly thereto.
Within the frame work (E, E), (which may be termed the stationary frame work) an adjustable" framing (F) is suspended in the following manner: pendant from the upper part of the frame work (F) are four bolts (l, l) and (2, 2) tapped at their lower ends and furnished with nuts. The bolts (l, l) support the brackets (3, 3) which slide in guides, (see front view, Fig. 4), and these brackets form bearings for a horizontal shaft (4) upon which two sockets (5, 5) are keyed which receive and support the arms (6, 6) attached to the framing (F), and at the right hand end of the shaft alever (7) is keyed as shown in the drawing. The bolts (2, 2) at the other end' of the frame work (E) support a cross bar (8) which carries the inner end'of the framing (F). This framing is attached to and forms one with the cast iron beds or gratings (r) and (s), (see Fig. 2.) which support the molds for forming the bricks, tiles, or other articles. VBetween these beds or gratings anti-friction rollers (g, g, g) are 40 loosely mounted, as shown in sectional elevation Fig. 3, the top of the rollers being on a level with the upper surface of the beds. At the lower part of the framing (F) arel bearings to receive a horizontal shaft 45 which carries a vibrating lever (t), to the upper end of which a lever (u) is jointed which branches out into the form'of aV and turns up at its ends at right angles; this is bolted to an axle (w) having on it a pair 50 of guide wheels (fw, lw); Ithese wheels are each provided with a flange which runs upon a rail (15) see Fig. 3, that is attached to the inside of the upper face of the framing; these rails (15) are curved down'- 55 ward on their upper edgeV as shown in the figure, the curvature being such as to prevent the forward portion of the axle or cross bar (m) from rising or falling as it is moved l`forward by the arm (t) as would 60 otherwise'be the v case from its connectionV with the arm (t) on a vibrating shaft, for it will be perceived the curvature of the rail so corresponds withthe curvilinear motion of the end of the arm (t) as to always keep the front part of the axle or carriage m 'j shown only in Fig. 4. To Vthe ends of the V shaped lever(u) a cross bar is bolted; (y) is a-lever for actuating the lever (t) and the parts connected therewith.
. Having described the various parts of the machinery whereby I am enabled to mold bricks, tiles, and other articles, I will now proceed to describe the action of the same. Rotary motion being given to the vertical shaft. (ZJ) of the pugmill, the plates (d, d) will force the clay through the opening (C) into the chamber (D) and supporting the mold to be placed upon the rollers (g) in the position shown at Fig. 3, the hand lever (u) is brought down forward, which giving rotary motion to the p-inions (m, m) in gear with the segment racks, will bring down the pressingplate (7c) and force the clay into the compartments of the mold; `when a sufficient pressure has been p-ut on` the clay by this means, the workman thenpulls down the lever (y) (letting go at the same time-the hand lever (n)) which action `will cause the lever (t) to 4advance and draw forward the lever (u), and with it the cross bar or axle (H), This bar (guided in its course by the wheels (w) will push forward a mold previously placed in front of it as at (e) Fig. 3 and drive that mold to the position of the mold nowfull ofclay from under the grating (g) in escaping from which ythe superfluous clay willbe rei moved by the inner edge of the inclined side of the gratings (g3). The full mold will then arrive at the position on theframing of the mold (z2) from whenceit is ready to be carried to the drying ground. By throwing up the lever (y) the bar (I-I) will recede to its former station and an` other empty mold being placed beforel it the same movement will be repeated after the vmoldv last pushed under the grating ('g) is filled with clay as before described. If by any accident a stone or otherhard substance should get into the clay and st-op the proper action of the molding machine it is only necessary to depress the lever (7) on the shaft (4) which will bring down the framing a suflicient distance for the mold to be released.
I would here remark -that in order to insure `the moldingof perfect bricks it is necessary to make` the cross bars ofthe grating (g) so that that face of the bars which is nearestthe center of the grating shall project farther over the divisions of the molds than their opposite face and thus Vthe free lateral course of the clay is regulated which will prevent the sand from being swept from the sides of the molds, as shown at (fu, lv), Fig. 4, by dotted lines (v) being the partitions of the molds.
To prevent the oscillation of the inner `framing (F) projecting pins are provided Which abut against the stationary frame Work (E) as will be seen in the Vplan at (y', j), Fig. 2. It is obvious that by employlng molds of a suitable shape and a grating (g) corresponding thereto my improved machine may be made to produce bricks and tiles of various, shape.
In conclusion I Wish it to be understood that I do not limit myself to the exact construction of apparatus above described for molding bricks as many parts may be modied Without departing from the nature of my invention.
What I claim as my invention and desire to secure by Letters Patent is- 1. The combination of the press with the pug mill, as above set forth so that While the clay is being pressed into the mold it the mill by Which much of the danger of breaking the parts is obviated.
2. I also claim thecurved railway in com- I bination With the movable carriage for forcing inthe molds, s'othat said carriage shall have its front at the same level at' all times. f
3. Lastly I claim the method of constructf ing the press so that the side plates do not require to be made with a slot in them, by carrying the shaft that connects the press with the segments back so as to be free to ac t as herein specified, Without passing beplate moves back to..
low the point the press ALFRED HALL. Witnesses:
