CONFECTIONERY-MACHINE.

7 V Specification of Letters Patent. Patented Nov. 28, 1911. Application filed July 5, 1910. SerialNo. 570,297.

' To all whom it may concern:

Be it known that-I, SPEERO PooLEY, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and-useful Improvements in Confectionery-Machines, of

which the following isa specification.

This invention relates to confectionery machinery, and has for its object to produce an improved machine for forming confections suchas cocoanut biscuits, macaroons and the like.

I Another object isto simplify and otherwise improve upon thev construction of machines of this class and to such and other ends this invention consists in certain novel features of construction, arrangement and combination of parts, a description-of which will be found in the following specification and the essentialfeatures will be more definitely pointed out in the, claims appended hereto.

The invention is clearly illustrated in the drawings furnished herewith,.in which Figure'l is a sideelevation of a complete machine embodying my invention, Fig. 1

Referring: to thefldrawin which illusiii-tea form, the

main frame of the machine is seen at 11, said frame comprising upright members 11, and longitudinally extending members 11", connectin said upright members to form a frame 0 substantial construction. Supported upon this frame are two side frames 12, that carry the operating mechanism for m'anufacturing'the goods. Upon one end of the side frames 12, is supported'a press 13, in which the material is placed and said press contains a substantially rectangular chamber 14, in which is slidably mounted a reciprocable plunger 15, operated from a rock shaft 16, by arms 17, secured to the shaft, and links 18, pivotally connected with the outer ends of thearms 17 and with ears 19, upon the rear end of the plunger 15. Arms 20, are secured upon the outer ends of the rock shaft 16, and receive their motion from pitmen 21, which are adjustably secured to said arms and operated by arms 22", of rocker members 22, 22, rotatively mounted upon a shaft 23, which is journaled in bearings upon the side frames 12. The rocker member 22, has a number of arms for actuating various of the operating members of the machine as will ap ear more fully later on in this specification. has a hopper 24, which opens down into the forward end of the compression chamber 14, and on the uppenend of the hopper 24, is journaled a-rock shaft 25, which has a blade 26, secured thereto, and adapted to be swung the forward end of the compression chamber 14. i The *rock shaft 25, is operated by arms 27, secured uponits end and pivotally connected with pitmen 28, whichare pivotally connected with the arms 29, of the rocker members 22, 22*. The forward end of the 'presshas a transversely extending wall 30, which contains a-discharge opening 31, through which the material is fed out into dies, where it is given its shape. A plate 32, is secured upon the outer face of the wall 30, and has a plurality of discharge openings 33, in front of the discharge openin 31 of the wall 30. i

The shaft 23, is located'in front of the press and has an intermittent rotary movement as w1ll' a pear later;

head contains the forming dies 36, in which The press I the material is molded or shaped. In the preferred form, said head comprises two die supporting members 34*,here shown in the form of circular disks, rigidly secured to 5 the shaft 23, and said disks are slotted radially as at 3-5, to receive the ends of the dies 36, and plunger carrying bars 37. The dies 36, are formed with a plurality of holes 38, of substantially the same size and shape as the discharge openings of the plate 32, which holes are brought to register with said discharge openings in the operation of the press. As shown in the drawings, four of these dies are provided on the head 34, and each die has lugs 39, which project into the slots 35, of the disks and is" guided to move longitudinally therein. The plunger carrying bars 37, are provided with plungers 40, that normally project part way into the holes 38, of the dies and said plunger carrying bars are also provided with lugs 41, upon their ends which extend into the slots 35, of the disks. Said plunger carrying bars are mounted upon adjustment screws 42, that are rotatively mounted in struts 43, 44,, extending across the slots 35, and said screws are provided with shouldered portions 45, 46, that abut against the struts 43, and against the bottoms of sockets 46, in the struts 44. Said adjustment screws are threaded as at 47 and engage with internally screw .threaded holes in the lugs 41'. It is evident, that by rotating the adjustment screws, the plunger carrying bars may be adjusted toward or away from the center of the rotating head to bring the outer or end faces of the plungers at the desired points within the openings of the dies, so as to increase or decrease the depth of the sockets formed between the walls of said openings and theend faces of the'plungers, thus determining the size and shape of the confecgtions molded or shaped by the dies. Be.-

tween the lugs 39, 41, are interposed springs 48, which hold the dies in their outward position to receive the, material from the press whenever they are brought into register therewith. Secured upon the inner sides of the frame like members 12, are two cams 49, which have cam faces 50, that are arranged to move "the dies 36, back upon the plungers to discharge the confections from the dies and the latter are provided with rollers 51, upon their ends, ,which rollers run upon the cam faces 50, and onto concentric faces 52,-that is to sa faces that are concentric with the axis 0 rotation of the shaft 23where they remain during theinterval that the rotating head is stationary. The cam faces 50, are so shaped and arranged that each die will be forced back sufliciently to expose the end faces of-the plungers therein, thereby exposingthe confections'which have been contained in the die;

A stripping device 52, extends transversely them after the die has been forced back.

As shown said stripping device comprises a piece of wire extending between the cams 49, and arranged immediately under the concentric faces 52, thereof, so that after the dies have been movedback to expose the confections, the wire will be in position to remove them.

Adjacent to the discharge plate 32, are two cams 49 for retracting the dies, as they move by said plate, so that the corners of the dies will not strike said plate., Said cams have inclined faces 50 with which the.rollers 51, contact and are forced back sufficiently so that the corners of the dies will clear ;the discharge plate. Recesses 50*, are provided in the cams'49 into which the rollers move as the head comes to a position of rest, whereby the dies may be forced into contact with the discharge plate by the springs, 48.

At some point between the discharge openings of the press and the point where the confections are stripped from the dies, is a roller or other smoothing device'54, which contacts with the outward faces of the dies and rolls upon the exposed sides of the confections to smooth the exposed surfaces thereof. This roller is movably mounted, and as here shown is carried by arms 55, that are pivoted upon the side frames 12, and yieldingly pressed toward the rotating head by springs 56, a stop 57, being provided to limit the movement of the roller toward the head. It is obvious that as the diepasses by the roller, the latter will follow the outer face thereof and press against the exposed side, of \the material contained in the die. I

Mechanism is provided for severing the material, which has been forced into the die, from the stock in the press, and as shown said mechanism comprises a vertically re .ciprocable lmife 58, carried by across-bar 59, which is secured upon the upper ends of the vertically reciprocable posts 60, that are slidably mounted in guides 61, secured to the 'side frames 12. The posts 60, receive their reciprocatcry movements from a pair of ,ec-

centri'cs 62, fast upon the main drive shaft A, and connected with the posts by pitmen 63. The knife 58, extends across all of the discharge openings 33, and'the mechanism is so timed that the knife moves down to sever the material after the latter has been forced into the holes of the die which is in register with the plate-32, andbefore the rotatable head begins to move to its next position. It isfound highly desirable to lubricate the knife so that the material will not stick .thereto, and, with this objectin viewI have provided a number of spraying nozzles 64,

upon a header 65, that is connected to .a suitable source of water'supply. The nozzles have projecting valvestems 66, which are arranged in the path of travel of the knife carryipg bar 59, and open the nozzles whenever struck by said. bar 59, In this manner the knife is lubricated each time that it operates to sever the material.

The rotatable head 34, receives its intermittent rotary motion from the rocker member 22*, which has a spring actuated pawl 66 pivotally secured thereto and arranged to engage with the teethv of aratchet 67, rigidly secured to the shaft 23. There are as many teeth upon the ratchet 67, as there are dies upon the head, and the rocker member'is given one forward and backward movement for each cycle of'operation of the machine. Both rocker members22, 22, receive this motion from eccentrics 68,- fast on the shaft A, being connected to said eccentrics by pitmen 69, that extend from arms 70, of the rocker members.

Means are provided for positively holding the rotatable head stationary during its periods of rest and as shownsaid means comprises a latch 71, secured to one of the side frames 12, and having a bolt 73, adapted to project into any one of the holes 72", in a collar 72, fast upon the shaft 23.' The bolt 73, of the latch is pressed toward the collar 72, by a spring 74, and remains in engagement with one of the holes in the collar during such period of time as the head is to remain at rest. A cam-block 75, is carried by the rocker member 22, and engages with a pin 76, upon the bolt ofthe latchto withdraw it from its engagement with the collar at such time as the pawl 66, picks up the ratchet 67. In this way the rotatable head is positively held in a stationary condition during its period of rest and is unlatched just in time to be moved to its next position. I

Mechanism is provided for lubricating the sockets in the dies and as shown said mechanism comprises a number of nozzles 77, that open out from a header 78, which receives its water supply through a flexible connection 79. The header is slidably mountedin ways 80, that are carried by the side frames 12, and said header carries a shaft 81, which is connected to rocker arms 82, by links 83.

The rocker arms are secured upon a rock shaft 84, journaled in bearings upon the side Below the operating parts of the-machine I is a conveyer adapted to support and convey the baking pans or boards underneath the head. As shown in the drawings, said conveyer comprises a pair of chalns 87, which travel over sprockets 88, fast upon shafts 89, 89 journaled in bearings upon the ends of two'rails 90. Said rails are secured upcn'the inner sides of the frame 11, and the upper bights of the chains 87, travel upon said rails. At suitable intervals the links of the chainvare provided-with laterally extendin lugs 91, which are adapted to propel the ba ing pans or boards B, that are placed upon the chains as shown at Ifig. 3. The chains are driven by an eccentric 92, upon the shaft A, which eccentric 15 connected to an arm 93, loose on the shaft 89*,-by a rod 94. The arm 93, carries a pawl 95, which cooperates with a ratchet wheel 96, fast upon theshaft 89*, to par tially rotate the same when thearm 93, is

moved in one direction; The arrangement of the parts is such that the conveyer will be moved a distance somewhat greater than the length of the confections made in the die, once during each cycle of the machine.

It is desirable to sprinkle the pans or boards B, with some substance, as for 1nstance powdered. sugar, and tosprinkle the upper-surfaces of theconfections with the same substance after they have been deposited upon the said pans or boards, and.

with this object in view I have provided a pair of shaking or vibrating sieves 97, 98, which are supported from the side frames 12, by links 99. .Said shaking sieves may be given a shaking motion to discharge'the finely powdered su ar, by any suitable mechanism, here 's own as toothed segments 100, fast upon the rock shafts 16, 94, respectively, and engaging with lugs 101, u on the sieves; It is obvious that as the s afts turn, the teeth of the segment will force the lugs back and move the sieves forward and that by providing springs 102, between the links 99, and frame,

the sieves will be forced in the opposite direction.

v Whenever the 'machine is driven from a high-speed power shaft, it is desirable to speed the machine down somewhat and in order to accomplish this I have provided gearing between the shaft A, and the power shaft, which as shown, comprises a gear wheel 103, 11 on the shaft A, a pinion 104 fast upon a s aft 105, journaled in bearings upon the frame of the machine, a gear wheel 106 fast upon said shaft 105, and meshing comprising with a pinion 107, fast upon a shaft 108,

journaled in bearings upon the frame 11,

thereby causing the nozzles 64, to spray the;

knife, and the stems of the nozzles 77, have been brought forward into engagement with the plungers in front of them to spray the sockets in the die. the plunger 15, and nozzles 77, are moving that the shaking sieves 97-, 98, will be agitated to sprinkle the baking pans or boards and the completed confections. When the plunger .15, has reached its limit of compressing movement, and begins its return movement, the knife is brought-down, thereby severing the material in the full die from the remainder in the press, after which the pawl 66*, on the rocker member 22, strikes a tooth on the ratchet 67, and turns the head one fourth way around, thereby bringing the full die down to its lowermost osition. As said die leaves its position in out of the plate 32, it is forced back slightly by the cams 49 and as it passes by the roller 54,

said roller smooths down any uneven places on the exposed side'of the confections contained in said die. Just before coming to its position of rest, the die is forced back sufliciently by the cam 49, to completely expose the confections, which engage with the stripping device 52*, and are thereby positively removed from the'plun ers. The conveyer is shifted by the eccentrlc 92, and the pawl and ratchet mechanism 95, 96, to

move the confections deposited on the baking board or pan out of the way of the next batch. \Vhile the confections are being discharged from the ,lowermost die, another die has been brought into register with the discharge openings of the press and is being filled with material, and the operation just described is again gone through vious that the discharge end of the conveyer may run to or through or over a baking ovenlor other heating device by simply extending said rails .sufiiciently and placing plate or other heating apparatus about it.

It is obvious that in place of the dies shown in the drawing, other dies may be substituted therefor having holes of different contours, so that a variety of shapes may be given the confections. In Fig. 12 a, rep- It is obvious that while It is obresents a confection made in; dies like those shown in the drawings, wh le I), a, represent confections made from dies having holes corresponding in shape to said contion shown and described.
