The operation of the machine is in general as follows:

Starting with the left-hand unit, the operator closes the female molds on the mold carrier and moves the batter supply mechanism into registration above the closed molds. He then operates a handle by which a multiplicity of nozzles are opened to discharge a predetermined quantity of the batter into each mold cavity. The mold carrying frame is then moved rearwardly on its slidesinto a position of registration with the burners below and the male cores above. By operating another lever at the forward end of the unit, the core carrier is caused to descend into the molds forming the batter up around the cores and closing the cavity provided between the side walls of the female molds and the outside walls of thecores. In giving this movement, the operator works the cores up and down slightly, allowing expansion to take place and the steam gases to escape, after which the cores are secured in baking position by a toggle effect of certain levers in the actuating mechanism.

The operator then proceeds in the same fashion with each one of the eight, or more units of themachine, the length of time taken to perform these operations on the remaining units of the machine being gauged to allow the complete baking of the batter introduced in the first unit. The operator then returns to the first unit, operates the core carrier to raise the cores out of the mold so that the subframe with the finished baked cones may be withdrawn from the oven and located over a discharge trough. In this preferred embodiment of the invention the female molds are arranged in separable halves so that by the use of a hand extractor having a series of properly spaced projections, the operator may split or separate the molds and push off the cones at the same time. As the cones are pushed off, they fall from the open mold halves and are directed by the discharge chute usually through the floor of the building to another department where they are stacked and packedfor shipment.

Referring now more particularly to the drawing there is indicated at 20, (Fig. 3) a flooring through which passes a discharge chute 21 having an enlarged mouth 22.

The main frame is built up from the fioor- 7 ing by spaced uprights 23, longitudinal angle irons 24 at the rear of the machine, and longitudinal irons 25 at the front of the machine.

'core.

uprights 23. Upper slide bearing pieces are fixed to the rails 26 and lower slide hearing pieces 31 are fixed to the members 29, the structure forming vertical slide bearings for a core head 32 which has oppositely disposed vertical slides 33 arranged in the bearings.

Lengthwise of the machine, but traversing the individual units thereof, is a pair of rails 34. These rails are supported by uprights 35 from the flooring 20, the uprights tying to the rails 26 as indicated at 36. The rails 34 extend some distance beyond the extreme left hand unit as shown in Fig. l. of the drawings so that a batter supply mechanism 40 arranged for sliding movement on the rails may be movedto a position of rest beyond the units, enabling the operator to manipulate the molds of the first or left hand unit without the interference of the batter tray.

The fuel supply is by a gas main 41 coming through the flooring 20 and from which separate feed frames 42 run to the individual units between the rails 26. The feed frames 42 supply thefuel for heating the mold units from below. For heating the cores on the core head 32 a series of pipes 43 is fixed above the core head and connected to the main 41 by flexible conductors 44. Individual valves are provided for the core gas feed and the mold gas feed and these valves are controlled by handles or hand wheels 45 and 46 respectively, arranged at the front of the'machine and at each unit.

The mold carrier'27 of each unit is in the form of a rectangular frame 50 in which are journalled wheels 51 adapted to roll on the track constituted by the spaced rails 26. The side pieces 52 of the frame 50 form a slide for a plurality of split female molds 53, the'frame being sufficiently long to permit the comple- 'mental mold sections to be separated successively to allow the baked products to be extracted. Each pair of female molds is formed with mold cavities 55 so that when closed a cup or cone shaped opening is formed to receive a charge of batter and the male In this present embodiment of the in vention there are eight baking units. Each baking unit comprises ten mold pairs and each mold pair is formed with seven cavities. The baking time allowed for each unit is from two and a half to three minutes. This allows the operator suitable time to do the unloading and refilling operations on the remaining seven units, returning to the first unit at the end of the baking period to unload and refill. The capacity of the machine is, therefore, per unit of baking time five hundred and sixty cups or approximately ten thousand per hour.

The core head 32 carries seventy male cores each mounted on the head by a bolt, the shank of which passes through a hole in the head slightly larger than the shank. This allows the cores a slight lateral shaft in any direction to adjust the cores to the molds when the head is moved downwardly into forming and baking position. v

The actuating devices for the core head and the mold carrying frame are shown best in Figs. 1 and 30f the drawings. On' lugs 61, spaced on and projecting from the front cross piece of the mold carrying frame, two arms 62 are pivoted. These arms with a cross connecting rung 63 constitute a handle by which the said frame may be withdrawn from and returned to the burners. The arms 62 extend I upwardly or inwardly beyond the pivot points onlugs 61, and pivotally connect at 64 with links 65 which in turn-pivotally connect with lugs 66 secured to the front wall of the most forward femalemold section 53.

When the handle 63 is moveddownwardly around its pivot on lugs' 61 the forward moldsection is moved forwardly separately from itscomplemental section. Theother I molds are then broken by the operator with the useof a handle 7 0 shown by dotted lines in Figs. v4 and 5, the handle having a cross bar 71 reinforced by diagonal struts 72. The cross bar has a plurality of depending fingers 7 3 of suitable shape and in number correarated from the walls of the 'mold cavities I and they then dropto the chute 21. The completion of this operation leaves the molds as shown in the second unit of the machine in Fig. 1. of the drawings. "The'operato'r thenmoves the handle upwardly, which, through links 65 moves the mold sections back. closing the gap at'the rear of the mold carrier and locking the sections together'by a toggle effect of links and lever arms'62, as clearly shown in Fig. 3.

The core heads are moved upwardly "and downwardly by handles and connected links and levers as follows. ,Ineach'unit the slides 33 to which the core head is connected have attheir upper extremities a connecting cross pivoted link couples the bar bar 80. A 80 with one end 81 of a beam 82 fulcrumed at 83 on the main frame. Theother end- 84 of the beam is pivotally connected at 85 to the upper end of a link 86, the lower end of which has a pivoted connection at 87 with v an arm 88 journ'alled in a fixed bracket 89. Thearm has a connection by means of a long link 90 with a lever 91 j'ournalled in a fixed bracket 92 at the front of the machine. The

upper end of lever 91 is formed as a handle 93..

Movement of the: handle upwardly into the position shown by the full lines in Fig. 3 forces the core head down causing the cores to enter the mold cavities and finally locks theparts .by a toggle efi'ect oflink 86:.and v arm.88. A counterbalance weight 94 is suspended from the end OfllllQ beam 82 to assist the operator in lifting the. core head. .Sheet metal cover plates 95 may bearranged over; the gas feed for the core head, asshownin" Fig. 1 for the purpose of confining the heat.

In the modified form of core actuating means shown in Figs. 9and,10 of the drawings,- additional pressing and toggle. locking means are employed for the purpose of applying pressure at a plurality ofpoints on theocore head. An extra framelOO is built up on each rail 26, supporting a cross bar 101. Journal boxes 102on either side of the unit centerv line, have pendant links 103 connected to link" 104 by pivot'pins 105. Thelinks 1 04connect to the crossbar, 80 in the same manner'as links 80 are connected. Pivotally secured to the. joined ends of links 103 and 104 by the pivot pin 105' is a linkol06 which'connects at 107 with a forked connection 108. Opposite V with extensions 110 of the uprights 23, .and

below at 11 1 with the arm 88 by pivot pin 87.;

By this construction the arm 88 controls the toggle links 103 and 104 as well as the toggle link 86. Movement of'the handle 93 applies pressure at three jpointson the' cross-bar of the core head and locks the. latter with its 7 branches of the fork ,108connect above at 109 cores. in-vthe molds by actuatingthe three toggles. Generated steam 'and the batterexpansion under the heatofthe molds-exerts a great upwardpressure'on the core head. The

modified form of "locking'means serves-[to resist this pressurekand holds" the core headfirmly down against the molds, fresulting in a high degree of cups.-,.

The batter supply mechanism '40 comprises bearings in straps 121. the batter supply tray may be moved along when all have been supplied the tray may be returned to a positionat the left ofthe machine out of registration with'any of them.

The tray l20 has a sheet metal bottom 124 andupstanding walls .125 (Figs. 6, 7 and 8). Spaced barsv 126 extend lengthwise of the tray and partitions 127. are provided to: fill the spaces between the bars. These "partitions have their tops infthefform of an inverted V,

as clearly shownin Fig. 8,'permitting the bat-' ter to flow and fill the spaces between the partitions. Discharge openings 128 are formed the bars and'tray' bottom, the openings belng normally closed by a frame comprising a-I'nultiplicity'of closure slidesql29, one for uniformity 1 in the baked each opening, spaced apart and connected in rows. to slide bars 130, which in turn are atg tached toa cross bar 131. The port closure frame is operated by a handle132 fulcrumed 1 "105 a rolling tray suspended bystraps121y. from rails and having rolling engagement, thereonby meansof wheels122having their I By this construction 5110 a the rails to register with successive units and at 133 on a lug 134: projecting from a cross bar 135 which is a part of a subframe connected to the main frame of the tray.

The handle 132 at its lower end has a pin and slot connection with the cross bar 131 of the part closure frame. A spring 136 pulls the handle in a direction to close the discharge opening.

After the mold carrier has been withdrawn from the ovens, the contents of the molds discharged, and the molds re-closed as herein previously described, the batter supply tray is moved along the rails into exact registration with the mold carrier. The operator then moves the handle 132 opening each of the ports 128 simultaneously, letting drop a quantity of batter in each of the mold cavities. As the operator releases the handle 132 the spring 136 returns the slide frame to close 'the ports. An equal quantity ofbatter is dropped into each cavity. An adjustable stop 140 is provided for arresting the movement of the handle 132. The operator re leases the handles as soon as this stop is reached so that by varying the position of the stop the opening time of the ports may be varied. This provides for gauging the amount of batter delivered to the molds.

To more accurately determine the amount of batter delivered, the form of delivery tray shown in'Figs. 11 and 12 may be used. In

this formthe tray bot-tom is above the valves as indicated at 150 androtary plug valves 151 are arranged below. The valve casings 151 have upperandlower ports 152 and 153 respectively. The valve plug has a port 154: adapted to be moved into and out of registration' with the inlet port 152. The plug has an outlet port 155 adapted to be moved into and out of registration wit-h the delivery port 153. Lengthwise of the valve plug, which is hollow,'there are partitions 156 forming chambers, so that when the tray is filled with batter and the valve inlet ports registered with openings 157 in the tray bottom, a quantity of batter will be received in each chamber. Each valve plug has at one end a lever 158 connected to a bar 159. The bar is operated by a handle 160 between adjustable limiting stops one of which is shown at 161. If desired a spring may be used for elfecting the return movement. 7

The split female molds are shown as having top'plates 170 providing lips 171 with recesses 172 for the batter overflow.

The advantages of these plates are fully set forth in my copending application Ser. No. 77,910, filed December 28th, 1925, for improvements in automatic machines for making cup pastry. These plates have one special advantage in the present machine not apparent in the automatic machine. The lips 171 form the opening which receives the fingers 73 of the extracting rake 70.
