T at whont ii ntaq concern:

Be itknown that I, GEORGESAMUELBAKER, a subject of the Kingof England, residing at London, England, have inv nted Cert-all! new and useful Improvements in Sugarater- Biscuit Machines, of which the following is a specification.

This invention relates to the construction of automatic sugar-wafer-biscuit machines is for the production of wafer-sheets, inwhich the batter of the wafer-sheet is baked between two heated plates, and has more par ticnlarly reference to the manufacture of wafer-sheets with indentations, cups, or other 1-5 shapes such as would not readily allow the hinged plates of an ordinary sugar-wafer-biscuit machine or tongs being employed.

In constructing a machine according to my invention provision is made for the separat- 2o ing of the two plates forming the wafer-tongs and the raising of one from the other for the purpose of filling .in the batter and also removing the baked sheet of waters first by a movement which separates the plates at an equal distance from the four corners, the one being raised perpendicularly and parallel with the other, and, secondly, a fur her separation by means of a hinge, thus causing one plate to open at right or other angle to o the other and giving access to the interior of the plate 4 In one form of machine T construct the bottom part0? the wafer-tongs upon the circumferences of a hollow wheel or drum, which is 5 set in a suit ble casing of brickwork or other non-conducting material, with provision for the heating or" the plates from the interioror exteriorpf the drum by means of suitable gas-burners or other heating appliances The 0 drum is supported upon spindles El -.1 may be worked by means of gearing provided with a stopping device for arresting the wafer-tongs periodically at the point where th platc are filled and discharged, Each of the tcp'plates is carried in aframewcrl; to which itishinged. Each of the frames for carrying the'to p plates is carried by segmental flanges in annular grooves placed concentrically with the drum carrying. the bon1 plates. A portion of each of these annular grooves is cut out 1W PQWF EQEEAP tq segmental grooves corresponding with. the annular grooves are made to carry the frames:- at this ll-i.', -h'0l.l1":'.1 when the trams carrying '55 the top plate comes opposite tothis' point the drum is arrested by the stopping device and the frame carrying the top plate 'is away-from the drum by means of camiiie'chR- anisni or other device. This lifting motion causes the two plates to separate parallel from each other, thus giving the first separating motion. As the plates are further separated by the continued movement of the frame away Zrom the druma projection on the plate in a suitable position withregard to toe hinge-" jointcomes in contact with a fixed stop upon the frame'of the machine, causingthe top plate to revolve upon its-hinge to such angle with reference to the bottom plate as may be determined. v

The stopping device may be constructed with an interrupted disk with a lever or cam so arranged as to work in connection with a star-wheel at such time as the interruption in the d'sk (.Jmes into position for the said lever or cam to operate the said star-wheel. At all other times the uninterrupted portion of the disk will engage with a corresponding portion of the star-wheel to lock same and prevent the drum turning upon its axle.

Other devices maybe employed for auto: matically stopping the drum. The waferv tongs instead of being set upon the surface of a drum may be entended into an endless band revolved bysuitable gearing, or the plates may lie horizontally and radiate from a vertical a is.

A locking device may be arranged to hold the ates together when filled with batter. After the batter has been filled into the lower plates a cam arrangemert may be-brought into operation to lower t re sliding segments of annular grooves to the r first position, thus allowing the top plate 5' st to close upon its 5 hinges-udtil such a time as it again becomes parallel with the bottom plate, and, as the sliding'segment comes to its first position, making theannular ring complete, the plates are broughttogether-and the drum, together to:

the top plates, is

plates with batter by means of pumps or other appliances controlled by'cams or'other working parts of the machine.

A convenient construction of apparatus for carrying out my invention is illustrated in the accompanying drawings, of which Figure l'is a plan of the machine; Fig. 2, an elevation of one side, and Fig. 3 an elevation of one end, of the machine; Fig. 4, a vertical section on the line 44 of Fig. 1. Fig. 5 is a sectional elevation showing the molds cover raising and lowering device. Figs. '6 and 7 are detached views of the drum rotating and locking mechanism in locked and rotating positions, respectively, the mold-cover raising and lowering mechanism being also shown in their relativelycorresponding posh tions. and pump-piston-operatingcams, illustrating their extreme positions, respectively. Figs. 10 and 11 are views of mechanism of the pumps, showing positions corresponding, respectively, with the position of the pumps shown in Figs. 8 and 9. Fig. 12 is a plan view of the pumps and part of their operating mechanism. Figs. l3and 14 are diagrammatic views illustrating the starting motions. Fig.'15 is a plan, and Figs. 16 and 17 elevations, of a'modified form of machine in which the molds are arranged on one end ofa drum rotating ona vertical axis; and Fig. 18 an elevation, ofa form of machine in which the molds are carried on an endless band.

Like letters indicate like parts in all the drawings.

The machine is provided with six .wafer trays or molds, each mold being arranged to make twenty wafers and comprising a bottom and upper plate A and A, respectively. The bottom pla tes A of these trays carry the matrices for the wafers and form the circumference of a drum B, carried on hollow trunuions B Birotatahle in bearings 0, formed in the side plates 0 of the frame of the apparatus. Fixed onthe outer end of the trunnion B is the dru m locking and rotating wheel B The wheel is provided with six locking-curves B and six actuatin slots B ,-alternatiu with.

the curves B Secured on a rotatable shaft D, carried in bearings formed in the side plates of the frame of the machine, is a locking-disk B Figs. 2, 6, and 7, the curve of whose periphery corresponds to and is arranged to engage in the curves B A portion of its periphery is cut away at B, so that as the disk revolves that portion is free of the drum-wheel B Fixed on the same shaft D and placed so as to cut the portion B of the disk B centrally is a short arm [3 having a pin B arranged as the shaftD revolves to engage in one of the slots B of the drumwheel B The pin .8 preferably carries a roller. It now the shaft D' be revolved while the periphery of lhe'disk B corresponds with one of the curves B, (as shown in Fig. 6,) the wheel B and consequently the drum B, is held motionless and locked, but-when the'cut-away Figs. 8 and 9 are views of the pumps.

the operating" the side frame-plates C yon'd thefnlcrhnrpin has a ;A ending in a nose'A which engages a .portion B corresponds with the wheel B as shown in Fig. Z, the latter is free, and the pin vB being 'now engaged in one of the slots B the wheel is rotated through one-sixth of a revolution. 1

v To rotate theshaft D, the following' device (shown most clearly in Fig. 13) may be provided. On the end of the shaft D is a loose pulley D, connected by a belt with a source of power and kept constantly running while the machine is at work. Fixed onto the pulley isa toothedwheel D and one member D of a clutch. Arranged on the shaft D so as ,to revolve .with it, but capable of-movement along it,- is the other clutch member D arranged -to be operatively engaged with the memberD by'meansof a forked lever B, rod D and handle'D; a spring D being provided to hold theclutch membersnormally inoper ative. Fixed onfthe shaft D immediately behind the clutchanember D is adiskD with a slot D in its periphery, adapted to engage a nose D on the lever D when the machine is in'its stopped position,-as shown inFig's. 2,

3, and 4. If now the operator pulls the handle DF, bringing the clutch D D into operative position, the nose D is disengaged from the disk-slot D and the disk revolves with the shaft D. If now the handle is atonce released, the nose-D comes in contact with the surface of the disk, and the clutch consequently remains operative during one revolution, at the endof'whic'h the nose, under the action of the spring D again engages with the slot and' the machine stops. Thus each time the operator pulls the handle D the drum revolves one-sixth of a revolution, removing one mold and bringing the next into the top position.

The upper plates A carry the mold-cores A and are each mounted on a sliding frame consisting of an upper flange A and side plates A, one on each side of the drum. Each plate A.i -s fastened onto one side of its frame-flangeby hinges A and has one or more lugs A, adaptedwhen' the frame is raised to ehgage with a nose or noses A", fixed on the frame'of the machine.

The side plates A are carried inslides A", Fig. 4, formed on the sides of the drum B and are provided with curved flanges A adapted to runiu grooves C ,;formed in the side plates C when the plate-frame is lowered. Each groove C forms a complete circle in which the corresponding flange A runs as the drum B revolves; but at their upper portion instead of being formed in the frame of the apparatus it is placed in a slider A adapted to reciprocate in vertical guides in The slider is reciprocated'by means of a lever A, Fig. 5,

-pivoted. on a pin A on the machine-frame.

One end of the lever is provided with a slot A in which works a pin A carried on the slider A The otherend of the lever becurved portion cam A fixed on the shaft D, before referred to. This cam and lever raise the slider, and the weight of the slider and parts carried by it tend to lower it when the raised portion of the cam, is disengaged from the lever-nose; but to insure certainty in the closing action a second lever and cam are preferably provided, as follows: Fixed to the boss of the lever A is a short arm or lowering-lever Al 'with a pin A engaged in a cam-groove A formed in a second cam A on the shaft D.

. A slider and its reciprocating mechanism are preferably provided, as shown in the drawings, for each side plate of the mold-cover frame. I

As before described, the locking-disk and rotating arm for the drum are also carried on the shaft D, and the raising and lowering mechanism for the slider is so arranged relatively to the rotating and locking devices that the frame carrying the upper mold-plate commences to rise directly the drum stops and is lowered before the drum again starts. Thus each time the handle D is pulled by the operator the upper mold-plate is lowered, the next mold brought into position, and its upper plate opened ready for the wafers to be removed and fresh batter placed in the molds.

. by two slide-blocks G In order to hold the plates A A of the mold closed when the drum is revolving, a circular flange 0 Fig. 5, is provided on one of the side plates 0 which corresponds with the curved end of the upper plate A.

The following mechanism is provided in order to automatically fill the molds with batter. This mechanism is shown detached in Figs. 8, 9, 10, 11, and 12. Placed at one side of the moldis a series of pump-cylinders E, equal in number to the rows of matrices in each mold. This number is arbitrary. Conveniently twentyare used, as shown in the drawingsviz., four rows of five each. The pump-cylinders are carried side by side on a cross-bar G, each end of which is formed in- 'tegral with or bolted to a slide-block G, adapted to reciprocate horizontally in guideways G placed one on each side of the machine. Each slide-block G is hollowed out to form a chamber G in which is a coiled spring G one end of which abuts on the bottom of the chamber, the other against one side of the end G of a cross-bar G the ends G being also adapted to slide Within the guideways G The ends of the pump piston-rods E are fixed to this crossbar, and carried in lugs toward each end is a small roller G each held by the tensionof the springs G against the periphery of acam G3. These cams are fixed .on a shaft G rotatable in bearings formed eachmovably held within one ofthe guideways G Each pair of slide-blocks G G are rigidly connected together by a spindle G, the ends G of the cross-bar G being bored to permit of these spindles passing through them. The pumps E are Single-acting pumps of known construction, each having a valve E discharge-port, which is connected toa pipe E of a length sufiicient for its mouth to reach over the wafer-matrix farthest from the pump when this is in its most forward position, as shown in Figs. 1 and 8, and a valve E controlling the suction-port, which is connected to a pipe E of which the free end dips into the batter-tank E, supportedon the frame of the machine between the guideways G but at a lower level. The pistons of the pumps are operated by the springs G and cams G previously referred to; but it is evident that besides operating the pump-pistons it is necessary to bring the end of each dischargingpipe E successively over each of the five mat rices in its corresponding row and also to draw it clear of the moldswhile these are being opened and shut. The following mechanism maybe employed for this purpose: Fixed on one end of the rotatable shaft G ,which carries the cams G is a toothed wheel G gearing with a toothed rack G carried on the machine-frame outside one of the guideways G Extending across one side of the machine and carried in bearings in brackets O is a rock ing shaft G, ,'on each end of which is fixed one end of an arm G the other end of which is connected by a link G to the pump-cam, carrying shaft G 1 Carried in bearings O in controlling the brackets fixed on the machine-frame above the brackets G is a shaft H, carrying an eccentric H, of which the rod H is pivoted to the free end of an arm G fixed on the rocking shaft G. The shaft H extends beyond the framework of the machine on one side and has running free on that end a toothed wheel 11?, gearing .with the constantly-rum ning toothed wheel D before described. The wheel H carries one member H of a clutch,

and a similar arrangement to that already described for revolving the drum-operating shaft D is provided for the shaft H, comprising clutch member H forked level-H 11 disk H H", rod H handle H spring H This arrangement is seen most clearly in Fig.

13. The mechanism operates as follows: On

the operator pulling the handle H the clutch members H H are engaged during one coinplete revolution of the-shaft H. If new the pumps are in the position shown in Figs. 9

and 11-that is, farthest removed from'the molds with the cylinders filled with batter and the delivery-pipes E clear of the molds the shaft H, revolving the eccentric H by means of rocking shaft G arm G and link G gives a forward movement toward the molds of thepumps and their connections, the slide-blocks G G being rigidly connected together. At the same time the gear-wheel G is rotated by the rack G and the cams G are revolved. These cams are so shaped and positioned, as shown in Fig. 9, that as the cam begins to revolve no movement is given to the pump-pistons, allowing the nozzles of the pipes E to be brought over the first matrices of the mold without the discharge of a I v 712,473

batter. As the cams continue to revolve they drive in the pump-pistons against the tension of the springs G discharging batterinto the fire-molds until the eccentric has made onehalf of a revolution, when the pump-pistons are at the end of their stroke and the discharge-pipe nozzles are over the last matrices of the rows in the position shown in Figs. 1 and 8. The lever G now commences its return stroke,-'the pressure of the springs G returns the pump-pistons, sucking up batter from the tank E through the pipes E and the pumps themselves are returned into the position shown in Fig. 9, with the dischargepipes E clear of the molds. orator pulls the handle D, the upper cover of the mold which has just been filled is lowered, the drum revolved, bringing the next mold into position and its upper plate raised," as beforedescribed. The operator can then remove the baked wafers if such be present and repeat theoperation.

The following mechanism (shown detached in Figs. 13 and 14) may be provided to make the opening and closing of a mold and the rotating of the drum follow automatically on the filling of the molds, so that the operator has only to pull the handle H to cause the 1 machine to make one complete operation: Pivoted at K in a bracket fixed on the frame of the machine is a bell-crank lever K, one arm of which is connected to the rod D while the other is connected to a square rod K carried in guides, so as to be capable of endwise movement, and with a nose having a vertical face K and an inclined face K Fig. 14, secured, preferably adjustably, on its outer end. Fixed on the pump cam-shaft G is a short arm K, slotted to receive a pivoted catch K, normally held, as shown in Fig. 14, by a spring K with one end abutting against the body of the arm. The other end of the catch projects beyond the arm, and the rod K is so placed relatively to the catch that at the end' of the backward movement of the pumps the catch K engages the vertical face K of the nose on the rod K pushing the rod back and through the cranklever K the handle-rod D thus setting the drum and mold-operating mechanism in action. On the return movement of the pumps the catch K engages the inclined face K of'the'rod-nose, and the spring K yielding passes under the nose without any action on the rod. The operator therefore by pulling the handle H causes the machine to perform one complete cycle of operations-viz., fill the matrices with batter, close the mold, rotate the drum, bring the next mold into position,;.and raise its upper plate. If, howev er-say when. stopping work-he wishes to empty the molds without refilling them, he pulls the handle D when the drum revolves, presenting another mold; but the pumps remain inoperative.

The molds are heated, preferably, by gassay by burners, as shown in Fig. 4. One, P,

If now the opplates, it is'evident that the one side plate to which the upper mold-plate is not hinged may be dispensed with, in which case only one set of operative mechanism for the frame would be used.

Figs. 15, 16, and 17 illustrate a modified form of apparatus, in which. the drum carrying the molds is arranged on a Vertical axis.

follows closely that'already described and doesnotrequire a detailed description. The drum instead of being driven directfby the wheel B is provided with intermediate bevelgear M M, as shown in Fig. 16.

Fig. 18illustrates a further modification, in which the molds are mounted in an endless band instead of on'a drum.
