Application f led November 9, 1811; Serial Ho. 659,301.

To all whom it may concern: Be it known that we, JOHN A; Gnome son and Jessie M. FLIOKINGER, citizens of the United States. residing at Kushequa, in the county of McKean'and State of Pennsylvania, have, invented certain new and useful Improvements in Brick and Block Machines; and we do declare the following to be full, clear, and exact description of the invention, such as will enable other skilled th art to which it appertuius to make and use the same. This invention relates to plastic block apparatus, and more especially to such as have a single mold with a cam-operated plunger and a cutter-rotating on the longitudinal axis of the machineyand the-object of the same is to produce improvements in a ma-. chine of this character. This and other objects are accomplished by the construction hereinafter more fully described and claimed and as shown in the drawings wherein- Figure 1 is a side elevation and Fig. 2 a

plan view of the machine complete; Fig. 3'

is a cross sectionon the line 3-3 of Fig. .1, and F igs. 4C, 5 and 6 are sections on the lines 4.--- l, 55 and 66 of Fig. 2; Fig. 7 is a front: elevation, and Fig. 8 a side View of the wire tightener on an enlarged scale, Fig. 9 is a side view thereof with the nearer pawl removed, and Fig. 10 is a section on the line 10 -10 of Fig.0; Fig. 11 is an enlarged perr-pective section ofthe gear ring and the outer end wall of the cutting mechanism,

.speciive (let: ii of the boil] g taken about on the line 111. 1 of Fig. (3 and on a larger scale; Fig. 12 1s a perthe cut-o'lt" plate.

in the drawings the numeral 1 desi ates the base of this improved machine which at one end -has bearings for the driving shaft whose pulley ills connected with any suit able source of power not shown. This shaft is connected as lily-gearing {with the main shaftj also -niouuted on the base and which, with its cams and eccentrlcs, constitute the driv ng mechanism 1) of this machine. The

latter consists broadly of theshaping mechanism S including a press box, a plunger.

therein operated from the main, shaft, a hopper, and a die; the cutting mechanism C to which the die delivers in a manner hereinafter described; and a brake B'interposed 1n the connections between the cutting mechanism and the driving mechanism so that the former is checked in its rotation at yoke for reciprocating proper times as will appear below. The de tails of the driving mechanism further than those that have been mentioned will be amplified below in conjunction with the de scription of the other coact.

The shaping mechanism S includes a press parts with which they box 10 (see Fig. 4:) having a hopper ll'at is connected by a link 16 with a yoke 17 which is pivoted at its lower end at 18 within the base 1, and whose side arms carry, loops 19 which are engaged by cams 20 on themain shaft 5. The plunger in the present embodiment of my invention is actuated by two rods 21 whose forward ends are pivoted to the plunger at 22 and whose rearward ends are connected with eccentric rings 23 mounted on eccentrics 24 which are fast on the main shaft 5.

The numeral 26 designates a valve located within an air inlet-port through the plunger 13 and drawn normally to its seat by means of a spring 27, the valve opening when the plunger is retracted by sald eccen-- t-rics so as to admit air at a proper. time to prevent the retraction of the plunger from drawing the molded plug of clay backward through the die 15.

' It will be well understood by those familiar with thisart that the clay is fed through the hopper 11 when the cutoff plate is retracted, and after a suficient charge has been fed into the box 10 the cams ,project the plate 12 and check the feed; and the parts are properly timed so that next the eccentrics come intonplay and the plunger 13 is moved'forward to compress the charge of clay within the box 10, force 1t toward and into the tapered extension 14, and

finally eject it through the mouth or die 15 p in the shape of a plug which has a cross section corresponding with that of the bricks or blocks to bcproduced and needs only to be out into proper lengths to turn out the finished articles.

The cutting mechanism 0 which operates in conjunction with the parts above de-i scribed is best shown in detall on Sheet 4 of the drawings and in connection with the other parts on the "remaining sheets. It

' 6, andthe rod stands at their axis; and

around their peripheries are tracks 34 on which more two rings 35 having radial gear teeth 36 by means of which the rings are driven in a manner yet to be described. On said rod 33 are loosely mounted collars 37- three in number in the present'instance although of course there might be more or less-and these collars are connected by ra- I dial wires 38 with rods 39also three in number in the present instance-which connect said gear rings 35 so that the latter are forced to revolve in unison around the circular end walls and the several wires 38 and collars 37 revolve with the rings. The outer end of each wire is by preference connected with a wire tightener best shown in detail in Figs. 7 to 10 inclusive. andcomprising a hook member 40 mounted loosely on the rod 39 and having a spring 41 within its body pressing radially inward against a bolt 42 which connects two dogs or pawls 43 whose teeth are thereby normally engaged with those of ratchet wheels 44 that are fast on the rod 39. The inner end of each wire 38 is carried by its collar 37 while the outer end. is secured to the hook of saidmember 40, and when the wire becomes slack or stretched the tightener' is manipulatedto take up the looseness thereof. Carried by said axial rod'33 are L:shaped teeth46, four in number in the present instance, properly spaced to permit the three wires 38 to pass between them as the gear rings 35 revolve, and the inner faces of the teeth are alined with the inner and lower edges oftwo rectangular openings 50 and 51 made through the walls 30 and 31 in line with the outlet end of the die 15. If the latter sits close to the inner wall 31, the plug formed by the shaping mechanism may pass therefrom into the cutting mechanism without any intervening means; but by preference 8. table or chute 52 is interposed to prevent the possibility of the plug of clay getting out of shape between the'time when it leaves the die and the time whexf it passes to the cutting-mechanism C.

The-brak B is herein shown as part of the driving mechanism for the cutter.

, Mounted on the main shaft 5 is a mutilated gear wheel 55 which meshes with a gear pinion 56 mounted on a shaft 57 the latter in the present: case being connected by gears 58 with a counter shaft 59 which in turn is connected by gears 60 with theteeth 36 of the rings 35. The parts are so timed that the toothed portion of the mutilated gear 55 engages the pm1on;.56' so astoactuate the cutting mechanism while the drivingmech opening 50 in the again out into bricks.

anism is retracting the plunger for a second stroke, whereas the blank portion of said mutilated gear 55 passes the pinion 56 and permits the cutting mechanism to remain idle during the forward movement of the plunger and when the plug of clay is being forced through the die into the cutting mechanism. But in order that the latter shall not under any circumstances rotate by momentum or even be turned by accident until the freshly formed plug has been passed into proper position to be cut by the wires, I make use ofa brake B interposed 'in the connections between the main shaft and the cutting mechanism and herein shown as composed of 7a band wheel mounted on the-countersh ft 59 and partly surrounded by a band 66 which constitutes the shoe, the same being connected to one end of a lever 67 pivoted at 68 in the niain frame and having a pin or finger 69 in its other end. On the main shaft 5 adjacent the mutilated gear is a cam 70 (shown in dotted lines in Fig. 1) with which the tip of said pin engages; and all these parts are properly proportioned and timed so that the pin 69 drops into the low portion of the cam 70 and applies the brake just as the teeth of the mutilated gear'55 pass off the pinion 56 and its blank portion comes opposite to said pinion. The applicati n of the brake at this moment instantly c ecks the rotation of the cutting mechanism C just at a time when the'eccentrics are about to project the rod and move the plunger forward to eject the plug of cement.

We have not considered it necessary to go into details further than as above nor to give the proportions and materials of parts, because considerable latitude in these matters will be permitted to the manufacturer and may be embraced without losing sight of the principle of, our invention.

In operation the clay is fed thr-wt-fgh the hopper in'a manner forming no. part of the present invention, and compressed within the box 10 and ejected therefrom by the plunger as described above. Passing over the table 52 in the form of a plug, it is driven through the openmg51 in the inner wall 31 of the cutting mechanism and across the teeth 46, meanwhile pushing out the bricks or blocks which previous operation, and these pass out the outer wall 30 onto a suitable table whence'they are conveyedvto the proper point for burning. As soon as the plunger ceases its begins to recede, the cam 70 releases the brake B and the teeth of the mutilated gear 55 come into engagement with the pinion 56 so. that the cutting mechanism 0 is rotated one step and the pro ected plug of clay is wires 39 aroundthe peripheryofthe gear forward movement and When there are three have been cut at the I three such Wires be so many but what would assume while the rings :35 as shown, one step. will be one third of a revolution; but it is clear that there might, be a greater or lesser number than although there should not during the idle moment-s of-the cutting mechanism the plug of clay'can he projected-between two of the sets of wires 38. Fig. 6 shows the cutting mechanism with one set of the wires passing acrosstheline of the clay plug and between theteeth 46, but in Fig. the wires 38 are shoWnin dotted lines in the position they plunger is being projected forward. As the latter is re tracted its valve 26 opens to admit air to' the interior of the press box 10 whose cut-oli "plate 12 is thenuclosed, and this valve we partial vacuum find useful. for otherwise a -might be createdthereinor' the plug of clay sucked back a trifle through the die 15.

Just as the plunger has reached its rearmost fed 'into thevbox 10'.
