To all whom it nwz/omw w part at predetermined times movements of Be itknown that I, HOWARD K. KING, a citithe mold-box and plunger away from the anzen of the United States, residing in the city .vil and at other predetermined times to imand county of Philadelphia, in the State of part respectively to the plunger and the 5 Pennsylvania, have invented certain new and mold-box independently movements toward useful Improvements in Re-Press Brick-Mathe anvil, the construction and timing of the chines, of which the followingis a full, clear, mechanisms being such as hereinafter deand exact description, reference being had to scribed, whereby the clots of suitable size the accompanying drawings, of whichplaced in position upon the anvil with re- 10 Figure 1, Sheet 1, is an elevation of the forgard to the then-elevated mold-box and plunward or delivery side of the machine.

This shaft, through suitable crated upon, and mechanism adapted to imcams and connections hereinafter described,

operates all the movable parts of the .machine. It is driven by a belt (not shown) running over a pulley 3 on the end of a shaft 4, hereinafter referred to as the drivingshaft, also journaled in the frame and having on its other end a pinion 5, whose teeth engage those of a spur-wheel 6 on the camshaft 2. I usually mount a hand or fly wheel 7 upon the driving-shaft.

8 represents the mold-boxes (two in number in this instance) in a common partitioned frame 9, which are lined with hardened steel and whose ends may, if desired, be chambered out for steam-heating.

10 represents the plungers, that are fitted to and adapted to work vertically in the moldboxes.

11 represents T-shaped stationary anvils, as I shall term them, upon which the clot-s to be compressed are supported and upon which they are pressed by the plungers. These anvils rest upon an arched diaphragm 1 of the frame, and although I term them anvils they may be said to be stationary plungers, as they are in length and breadth but slightly less than the corresponding dimensions of the respective mold-boxes, so that the latter may in their descent pass below and closely adjacent to the sides of the anvils.

The necessary downward movement is imparted to the plungers 10 at the proper intervals as follows: The upper end of each of the plunger-rods 10 is secured to the lower limb 12 of a cross-head 12, that is adapted to slide vertically in guideways 13 of. inward projections 1 of the frame. The upper part of said cross-head has a transverse horizontally-rotatable shaft 14, to which are secured I connecting-rods 15, whose upper ends are secured to a similar rotatable shaft 16 of a crank-head 17, that has laterally-projecting studs 13, which are journaled in bearings of the posts of the frame of the machine. The shaft 14 and studs 18 are substantially in line vertically. Fixed to the crank-head 17 at an angle to the limbs of the former is an arm 19, which has a roller 20 at its free end that is adapted to ride on the face of a cam 21 of the form shown in Figs. 1, 5, and 10 on the camshaft 2. Secured to lateral extensions of the mold-box frame are vertical rods 22, whose upper ends are respectively pivotally connected to the lower cross-head 23" of a link 23, whose upper cross-head 23 is pivoted on the end of an arm 24 of a rock-shaft 25, Figs. 1 and 3, journaled in the main frame. On the latter shaft is also mounted a forked arm 26, the upper limb 26 of which carries at its free end a roller 26 that is adapted to ride 011 a cam 27 on the cam-shaft 2, and its lower limb 26 has a roller 26, that is adapted to ride on a cam 28, also on said cam-shaft. These cams are of the forms respectively shown partly in full and partly in dotted lines in Fig. 5 and seen in edge elevation in Fig. 1. The cam 28 operates to depress the mold-box and the cam 27 toraise the same at certain intervals and for purposes as here inafter explained. The cam 21 in its rotation serves only to depress the arm 19 of the crank-head 17,and consequently the plungers. In order to raise the plungers,I suspend a heavy weight 29 (indicated in dotted lines in Figs. 1 and 5) from the end of an arm 30 upon the projected end of one of the studs 18 of the crank-head 17. As, however, when the clot of clay has been re-pressed or molded a considerable force is required to retract the plunger, or rather to give it a start, I provide on the side of the plunger-cam 21 a cam ledge or projection 31', Fig. 1, (shown also in dotted lines in Figs. 5] and 10,) against which is adapted to ride at certain times in the rotation of cam 21 a roller 32, that is journaled on a lug 30 of the arm 19.

33 represents fixed plates or tables that are boxes.

Between and below the line of the top of the anvils and the tables 33 extends a horizontal bar 35, which I term the feed-bar, on one end of which is a cross-bar 35 at right angles to the latter, like the head-bar of a T- squa re, and projecting above the plane of the tables, as shown. The other end of the bar 35 is secured to and beneath the horizontal limb 36 of a gooseneck 36, and on the top of the gooseneck is fixed a horizontal plate 37, hereinafter termed the off-bearing plate, that is a short distance above the line of the anvils and whose inner end is upturned to form a flange 37, whose front edge is at right angles to the top of the plate, and its lower edge is beveled, as shown. The vertical limb 36 of the gooseneck is provided with flanges 36, that are fitted to and adapted to slide horizontally in guideways 36 of supportingbraekets 36 fixed to a part of the main frame. (Seen most clearly in Fig. 1.) The lower end of the gooseneck is pivotally connected by a rod 38 to an arm 39 of a rockshaft 40, that is journaled in bearings of the lower part of the frame 1. On the outer end of this rock-shaft is a crank-arm 41, to the free end of which is pivoted a vertically-extending rod 42, whose upper end is pivoted to the lower limb 43 of a bell-crank 43, that is journaled on a stud 43 that is fixed to and projecting from the side of the frame. The upper arm 43 of the bell-crank has on its free end a roller 43, that is entered in a cam-groove 44 in the face of a cam-wheel 44*, Figs. 1 and 4, on the camshaft.

The anvils have vertical vent holes 45 therein of comparatively-small diameter, preferably located as shown more clearly in Fig. 7, and whose purpose is to permit the escape of a certain quantity or excess of the clay during the process of pressing the clots in order to avoid liability of fracture of the machine and also in order that the successive bricks may be of-uniform size. In order, however, to obviate the escape of too great a quantity of the clay through said holes, I provide a mechanism for at the proper times cutting off the outflow. This cutting-off mechanism is as follows: Below the vent-holes of the anvils and adjacent to their neck are two similar rock-shafts 46 46, that are journaled in the main frame and extend transversely to the anvils. On the end of one of the shafts, 46, is an arm 47, with teeth on its free end that are in engagement with the teeth of a similar arm 47 on the other shaft, 46. Pivoted to a part or extension of the latter arm is a connecting-rod 48, whose upper end is pivoted to the end of an arm 49 of a bell-crank 49, that is journaled on a stud 49 projecting from the side of the main frame. The other arm 49 of the bellcrank carries at its free end a roller 49 which is entered into a cam-groove 50 in the side of a cam-wheel 50, that is mounted on the cam-shaft, as shown in Figs. 1 and 2. The configuration of this groove is most clearly shown by dotted lines in Fig. 2. Secured to the rock-shafts 46 46*, or rather to arms 46 thereof, are pins 51, whose upper ends are in such proximity to the line of the lower ends of the vent-holes 45 that when the pins are rocked outwardly they will cut off the noodles or small stems of clay that have been forced through said holes and will also close the latter at predetermined times, as and for a purpose hereinafter explained.

Having now described the construction of the machine (not going into minor details or describing parts tending to render the operation more perfect, which parts will be hereinafter described) and premising that the said several cams carried by the cam-shaft 2 are so shaped and timed as to effect at the proper instants or intervals the movements of the respective parts actuated thereby, I shall now proceed to explain the operation of the machine,as follows: The clots to be repressed, whose length and width are less than those of the interior of the mold-boxes, are placed upon the tables against the sides, respectively, of the guide-bar 34 at the time when the feed-bar has been projected to its farthest outward extent by operation of the cam 44 and its connections with the rock-shaft 40-that is to say, when the crossbar 35 is at the outer end of the tables 33, as seen in Figs. 15 and 16, Sheet 7. The latter figure bar 34 just after the re-pressing of the previous clot. Now as the cam-wheel 44 continues to rotate, and thus actuates the rockshaft 40 through the connecting-rod 38, &c., the gooseneck slides forward, and the crossbar 35", impinging against the rear end of the clot O, carries the latter into position upon the anvil ll, beneath the mold-box. As, however, the momentum is liable to carry the clot too far, and thus out of register with the mold-box, I provide a means for arresting the clot when it arrives at the required position. This consists in the present instance of a bent or approximately U-shaped spring 52, whose lower limb 52 is fastened to a bracket 53, that is secured to the top of the anvilsupporting diaphragm, and whose upper limb 52 extends above the plane of the anvil and its inner side is in line vertically with the inner edge of the mold-box on that side. The timing of the mechanism which actuates the feed-bar is such that when the bar has reached substantially the limit of its forward movement the clot G will impinge against the spring-stop 52. As the cross-bar 35 is then directly beneath-that is, in the path of-the forward wall of the mold-box, as in Fig. 11, it is necessary that it should be gotten out of the way before the box shall descend to incase the clot. \Vhen the said bar is at the limit of its forward throw, the roller 43 is riding in the rounded portion or swell (marked 44 Fig. 4) of the cam-groove 44, and as the cam-wheel continues to rotate the said roller enters the depression at 44 of the said canigroove, and a slight rock is thereby imparted to the shaft 40, which carries back the feedbar a short distance sufficiently to cause its cross-bar 35 to amply clear the line of the mold-box-that is, from the position of Fig. 11 to that of Figs. 12, 13, and 14, Sheet 7. The bar remains in this position until roller 43 passes from the semicircular part 44 and comes to the part 44 of the cam-groove 44. The mold-box now descends by the action of the rotating cam 28 upon the roller 26 of the lower limb 26 of forked arm 26, as in Fig. 12, and continues its descent, finally incasing the clot C, as seen in Fig. 13, the stopspring being at the same time depressed by the mold-box. The plunger 10 is now forced down by the cam 21, and thus the clot is compressed upon the anvil. Any excess of clay is forced through the vent-holes 45; but just before the final pressure is givenby the plunger the pins 51 are rocked outwardly by the action of the suitably-timed carngroove 50, in the high part 50", Fig. 2, of which rides the roller 49 of the bell-crank arm 49", that is connected by the rod 48 with the toothed arm 47 upon the shaft 46 upon which latter said pins are mounted, as before described. These pins break off the noodles and stop the flow of clay through the vent-holes. As the cam 21 continues its rotation and the roller 20 rides 011 the highest point of the cam, as in Fig. 10, the final pres- IIO 5 sure is given'to the clot by the plungers while the said holes are thus closed. This latter pressure while not wholly essential is designed to impart a uniform texture to the clay-that is, to compact that part of the clot at or about the points whence the clay has flowed through the vent-holes. The mold-box and plunger now being in the position shown in Fig. 13 rise thence to that of Fig. 14, the mold-box ascending through the action of cam 27 and the plunger by the weight suspended from the arm 30 of stud 18, it (the plunger) being, however, started by the positive action of the cam-ledge 31 of the cam 21 impinging against the roller 32 on arm 19, so as to overcome the suction of the clot to the anvil, as seen in Fig. 10. While at this time the plunger has reached its upward limit, the mold-box, still incasing the clot, (which has been carried up from the anvil by the box,) has, for a purpose hereinafter appearing, not reached its highest point. At this juncture-that is, after the box and plunger have ascended, as seen in Fig. l t-the feed-bar 35 is retracted by means ofthe before-described mechanism, suitably timed for actuating it, from the position seen in Fig. 14, also in Figs. 12 and 13, to that of Figs. 15 and 16that is to say, the off-bearing plate 37-is carried into position over the anvil and beneath the mold-box and the re-pressed clot therein, the lower beveled edge of said plate in its inward movement impinging against and depressing the spring-stop 52 out of the way, or rather against an incline 52, Fig. 9, upon the spring. The cross-bar 35 is also carried to the rear part of the table in position to slide the next clot to be repressed from the table to the anvil. The mold-box is now caused by its operating-cam 27 and connections to rise to its highest limit, as seen in Fig. 16, the distance from the under side of the plunger to the top of the off-bearing plate being a little greater than the thickness of the clot that has been operated upon. This ascent of the mold-box freeing the clot therefrom causes or permits the latter to drop upon the off-bearing plate, by which it is carried forward into convenient position to be taken away by the attendant of the machine, when the feed-bar is again advanced to carry the succeeding clot into position beneath the mold-box, as in Fig. 11. In order to insure the drop of the clot which may adhere to the plunger, I usually impart a final down: ward movement to the latter by providing the .edge of the cam 21 with a projection 21, of substantially the form shown in Figs. '5 and 10. This projection impinging against the roller 20 at the proper instant-that is, at the same time the mold-box is ascending to its highest limit-gives a slight descent of the plunger and with it the repressed clot, thus positively delivering the latter to the off-bearing plate.

'from the upper roller.

In order to obviate the liability of sticking of the top and bottom of the clot, I apply oil or other lubricant to these surfaces of the latter. This I do by the following means: 54:, Fig. 5, is a box or tank for containing oil, in the bottom of which is a pipe 54 having a petcoek 5t therein for allowing oil to fall or drip from said tank onto a roller 55, covered with felt or the like and journaled in bearings of arms 56, that depend from the tank. Directly beneath this roller are two second similar rollers 57, that are journaled in posts of a bracket 58, fixed to the frame of the machine, and whose peripheries are substantially in line with the tops ofthe tables 33, respectively. These rollers are located in advance of the line of the forward end of the tables 33 and a short distance to the rear of the line of the mold-box frame. The distance between the said rollers is substantially the thickness of the clot to be operated upon and in order to adapt the rollers for variations in the thickness of clots the bearings of the journals of the upper roller are vertically elongated, so that the roller may adapt itself to the clots. The lower rollers are supplied with oil by the dripping As the clot is carried between the rollers by the movement of the feed-bar its top and bottom will be oiled by coming into contact with the peripheries of the rollers.

In order to adjust the relative height of the plunger for clots of different thickness, I connect it (the plunger) to the limb 12 of the cross-head 12 in the manner shown most clearly in Fig. 9, Sheet 6, as follows: is a flanged tubular head which is secured to the top of the plunger 10 by means of bolts 60" and is internally screw-threaded to receive a threaded bolt 60*, with a contracted stem that extends through an aperture in the part 12, and is secured to the latter by means of a nut 60 in the projecting end of the stem, whereby the bolt is clamped to the cross-head, as shown. It will be obvious that byloosening the said nut and turning the bolt the plunger may be brought toward or away from the cross-head to suit the thickness of the clots to be operated upon. As it may sometimes occur that the resistance of the clot to compressionwill be such as to break or strain some part of the machine under the heavy pressure, I usually insert between a shoulder 60 at the bottom of the stem of the bolt (30 and the under side of the part 12 of the cross-head 12 a safety-washer 61, composed of soft metal or material, whose strength is sufficient to resist ordinary strains, but which will crush under abnormal pressure,and thus obviate fracture of the machine. The frame as well as all the parts of the machine are, however, made heavy and of great strength, having regard to economy of space.

The mold-boxes and vent-holes, as also all the parts of the machine that come in contact with the corners of the clot while pressure is being applied thereto, are preferably lined with hardened steel, as seen.

IVhile I have shown one way of carrying out myinvention, I do not wish to be understood as limiting myself to the precise constructions or mechanisms shown and hereinbefore described, as substantially-identical results may be attained with other mechanisms adapted to operate in substantially the same way or upon the same essential principle.
