VILILIAM H.

(These springs are simply straps of steel fastened at one end to the cross pieces of the frame of the carriage and supported about midway of their length, by a cross strap of iron or steel). F, F, is the curved lever or eccentric semicircle, which revolving with the shaft and playing against the friction rollers E, E, moves the carriage backward and forward horizontally beneath and parallel with the bottom or floor of the cistern. G is the shaft which should be in size about 39j inches square. Fig. 3 also shows with sufcient accuracy the relative positions of the filler and curved lever upon the shaft. As the shaft revolves, the curved lever playing against one of the friction rollers moves one end of the carriage out to deliver the mold, and places the valve under the opening at that end in its stead, and as the curved lever leaves this roller, the filler commences passing over the mold under the opposite opening to fill it, and by the time the filler has accomplished this, the curved lever has reached the other friction roller to move that end out for the delivery of its mold and vice Versa. The filler is represented in Fig. 3 by A the handle and B, the blade or inclined plane; (to give an idea of its dimensions we will state the size of the one from which this is drawn), length of shank or handle 2 feet from center of shaft extending across the back near the middle, to the outer edge of the blade; blade ll in. by 17 in., rounding on the outer edge reducing the ends to l0 in. in width; it may however be ymade of other dimensions suited to the size of the cistern and of the openings in the bottom. v

lraised edges of the floor on which the plank of the cistern rest. The dotted lines represent the additional openings and the partitions (if fixed partitions be used) when two mold cars are used. D the shaft or `hole where the shaft passes through.

The foregoing isa full description of the machine as used with one mold car or carriage; it may also be worked with two carriages or mold cars in the manner described as follows:

Fig. 5 represents in perspective the second carriage (drawn also on a scale of an inch to the foot, with suflicient accuracy to give an idea of its proportions,) with the first carriage as it runs across it, showing the relative positions of the two carriages at the moment when, as the shaft revolves, the curved lever (which moves both carriages F, F, Fig. 3) has passed by the roller under the upper valve of the upper or i'irst carriage and thrown or moved that end out far enough to deliver its mold, and is just commencing on the next, being the right hand end of the second or lower carriage to move it-s mold out and so on of the rest, one after the other; A A A A the rst carriage with its valves and friction rollers (as represented in Fig. 3) B, B, B, B, the frame of the second carriage running under that of the first; C, C supports or elevation of valves; D, D, surfaces or valves extending over their supports and elevated higher than the valves of the first carriage; under the valves are friction rollers (represented by` dotted circles) as in the other; the space between the supports of the valves (at the sides) of the second carriage; is greater than that of the first (see Fig. 5). This second carriage is supported and moves like the first on 2 rollers placed on the other two opposite sides of the cistern or frame, and runs across beneath the first carriage except its valves which rise above the valves of the iirst carriage and close up to the under surface of the floor of the cistern. Bot-h carriages are alike in principle and nearly alike in construction except the differences above pointed out. The second carriage has the same alternate horizontal motion as the first and is moved by the same curved lever playing against its friction rollers (so placed as to be even or level with the friction rollers on the other carriage). When two carriages are used, the floor of the cistern must, of course, have four orifices or apertures for the mortar to pass through, one at each of its four sides; two of these openings, those under which the first carriage runs, must have necks or raised edges on the under surface, so as to meet the valves on the first carriage, which first carriage, when two are used, runs lower (under the floor) than when used alone, (say to an in.) to allow the corners of the valves on the under or second carriage to pass over the corners of those of the first and to prevent the valves on the two carriages from hitching or coming in contact with each other; (these necks may also be used with advantage when there is but one carriage). rlhe sides of the frame of the second carriage are deeper from the valves outward than the rst, (as the drawing will show) so as to .u so

raise the molds even With its valves. The 2. And `We also claim the manner in which molds on both carriages are illed by the We have combined With the cistern and its same filler (described in Fig. 3). revolving shaft for tempering the mortar,

l/Vhat We claim as our invention and dethe mold carriages constructed and operaty 5 sire to secure by Letters Patent, is-` i ing substantially as above set forth.
