EDGAR D. MISNER, OF ST. LOUIS, MISSOURI, ASSIGNOR TO WILLIAM C. RENFROW, OF JOPLIN, MISSOURI.

BRIQUET-MAKING MACHINE.

Speoicaton of Letters Patent.

Patented Feb. 5, 1907.

To all 1071//11, 'luft/j con/cern.- A

Be it known that I, EDGAR D. MISNER, of St. Louis, State of Missouri, have invented certain new and useful Improvements in Briquet-Making Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, suoli as will enable others skilled in the art to which it appertains to make and use the same.

The primary object of this invention is to provide in a briquet-making machine means for preventing any of the pulverulent material from adhering to the walls of the feeder or supply-openings of the die-housing, insuring thereby in each operation the presence between the cooperating dies of an uniform amount of suoli material.

A further object is to improve the construction of several of the operative parts of the briquet-making machine shown and described in Letters Patent No. 796,921, issued to me August S, 1905, including thereby means for effecting the thorough agitation of the aggloinerated mass and preventing the same from adhering either to the walls of the inclosing casings or to the agitator-shafts and a further object is to enable the hot mixer and the agitators to be operated independently of each other and of the die-actuating mechanism.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation with parts broken away. Fig. 2 is a horizontal longitudinal sectional view with parts omitted.v Fig. 3 is an end view. Figs. 4, 5, and 6 show the dies, feeder,

and ejectors in various positions, together with the actuating means therefor. In Fig. l the die-carrying body is shown in section.

The die actuating mechanism is constructed substantially after the manner shown and described in my Patent No. 796,921. The main shaft 1 carries two large gearheels 2, which are rotated through intermediate gearing by the operating-shaft 3, driven by a belt a from a counter-shaft. (Not shown.) As in my before-noted patent, shaft 1 is connected by rods 5 with the central die-carrying body 6, said rods being litted on wrist-pins 7, projecting from the ends of said shaft. The relative arrangement -of the double set of dies 8 in the die-carrying body 6 and the outer end dies 9 to the inner end dies 10 is the same as pointed out in 'my said patent, the carrying-body 12 of vthe outer end dies and the carrying-body 13 of the inner end dies being connected to move in unison by nutted rods 14. The dies v8 are held in their carrying-body as against longitudinal displacement by nuts 14a, (see Fig. 4,) located within the chambered center of said body, and the dies are also held in perfeet horizontal position by coil-springs 14h, Fig. 4, mounted in openings in said body, said springs carrying the Weight of the dies to prevent friction on the die-housings.

The die-carrying body 13 is directly connected by rods 14d to frames 15, which are moved longitudinally by cams 16 on shaft 1, engaging idlers 17 of said frames. To provide for evenness of movement and perfect alinement of the dies, idlers 18, with which projections 19 of said frames 15 engage, re mounted in vertically-adj ustable bearings 20. These bearings may be readily adjusted by the turning of screws 21, working in the main supporting-frame la. (See Fig. 1.) These adjustable bearings carry loops 22, through which projections 19 extend, said loops serving to prevent the latter from jumping the idlers 18. In thepresent instance the reciprocating feeder 23, mounted on the connecting-plate of the two die-housings 24, is actuated by rods 25, each of which is connected to the upper end of a lever 26, fulcrumed at 27 to the adjacent side of the main frame, said levers at their lower ends being slotted for engaging with pins 28 of the reciprocating frames 15, the movement Whereof effects the rocking of levers 26 and the reciprocation of the feeder. The latter is provided with two series of pockets 29 for alternately feeding the pulverulent material to the vertical-supply openings 30 of the two diehousings, which latter openings intersect and empty into the horizontal openings, wherein the dies effect the compression of the material into briquets.

In order to insure the discharge of the material from the feeder-pockets and for forcing it from the supply-openings into the horizontal openings of the die-housings, I

IOO

faces of wheels 2..

provide two separate series of verticallymovable ejectors 3l, located directly above the supply-openings and capable of being lowered down through the several pockets of the feeder and into said supply-openings when the pockets are coincident with the latter. Each ejector of each series is shown in the form of a rod depending from a common cross-bar 32 andy carrying at its lower end laterally-extended wires 33 of brush formation. The cross-bars 32 at their outer ends arecarried downwardly and their ends connected at points beneath the dies and their housings by cross-bars 34. To these ,crossbars are pivotally connected the ends of levers 35 36, fulcrumed on a common rod 37 and carrying at their other ends rollers 38, which fit in cam-guidewa'ys 39, preferably7 formed of channel-bars secured to the inner opposite rl`he offsets in these camgrooves, as indicated in dottedlines, Fig. l, are so arranged relatively as to effect the alternate reciprocation of the two series of ej ectors. Y

40 designates the supply-hopper, between which and the die-housings the feeder 23 is designed to reciprocate. Within this hopper are two revolving shafts 4l, each carrying agitator-arms 42, the arms of each shaft in their revolution approaching closely to the other shaft, so as to prevent any of the pulverulent material from adhering to the latter. These arms are composed of rods passed through their respective shafts at rightangles to the axis thereof and deflected on each side of the shaft, so as to occupy an angular position relative thereto, as shown in dotted lines, Fig. 3. The shafts are rotated in opposite directions, so that the two sets of arms will conjointly lift the material and effect the thorough mixing thereof and at the same time leave it loose to fall into the pockets of the feeder. These shafts at one end have intermeshing gear-wheels 44, and on 4the other end of one shaft is a sprocketwheel 45, which is actuated by a chain 46 of a sprocket-wheel 47 on one of two shafts 48, mounted in a superposed hopper 49, said shafts also carrying agitator-arms 50, constructed similarly to the arms 42. The outlet from this superposed hopper to the feeding-hopper 40 is controlled by sliding doors 51 after the manner pointed out in my before-noted patent, said doors being actuated by a hand-wheel 52 on shaft 53. Access may be had to hopper 49 through doorcovered openings 53,

54 54 designate horizontally-disposed hot mixer-chambers, into each cf which the material is supplied at one end, such chambers having each a surrounding jacket to which and to the chambers themselves steam is supplied by piping 55. Centrally within each chamber is a shaft 56, carrying spirallyarranged agitator-arms 58, the blades of which are set obliquely to the plane of rotation, so as to effectively cut through the material and force it toward one end. The arms at their outer ends scrape the interiors of the chambers while forcing the pulverulent material therethrough. The shafts 56 are actuated in opposite directions by gearing 60 at the discharging ends, and the material is discharged througli passage-ways 61 directly into the superposed hopper 49.

The Agearing 6() for the hot mixers is actuated by a belt 62, driven by the same countershaft as that which drives the belt 4. @ne of the shafts of the superposed hopper carries at one end a sprocket-wheel which is engaged by a chain 63 which is actuated by` a sprocket-wheel 64 on a shaft 65, carrying a band-wheel 66, which is driven by a belt 67,

actuated from the same counter-shaft. By this means l am enabled to separately control the actuation of the hot mixers, the agitators of the hoppers and the mechanism for actuating the dies enabling any one or two of these to be operated alone. advantage when it is necessary to additionally work the material either in the hot mixers or in the hoppers, or in both, but without operating the dies and feeder.

The operation is as follows: The mass of finely-formed or pulverized material is deposited by any suitable means into the hot mixers, wherein in the presence of steam it is thoroughly agitated and caused to travel therethrough by the obliquely-set agitatorarms 58. The mass falls through passageways 61 into the superposed hopper, wherein it is still further agitated by the two agitators traveling in opposite directions, and.

from this hopper the material passes in regulated quantities into the feeding-hopper 40, where it is further worked by the two agitators. The die-feeder is being constantly reciprocated, its two series of pockets alternately coinciding with the outlet from the supply-hopper. The material filling such pockets is conveyed to the vertical supplyopenings of the die-housings and is forced into the die-openings by the vertically-movable ejectors 3l, which latter are alternately actuated by the rocking of their respective levers by cams 39. The material once deposited in the die-openings is acted upon by the several sets of dies and formed into briquets after the manner indicated in my abovenoted patent, such briquet falling from the die-housings onto a conveyer 68, by which they are carried beyond one end of the machine. This conveyer is shown in Fig. l as being actuated by a chain 69, operated by one of the agitator-shafts 41;
