This invention refers to ice-cream cone forming machines wherein a plurality of heated mould units and a like plurality of mould cones are used, arranged in rows n endless tracks and adapted to be moved in termittently along the tracks and to be transferred one by one from one portion of the track to another, the batter being supplied to the mould units at the commencement of their movement along each of said portions of the track and the baked cones being discharged from the mould unit.) on the latter completing their movement along such portions, the operations of filling, baking and dischargmg heing continuous.

The object of the invention is to provide an improved general construction of such machines, and in particular improved means for transferring the mould units and cores from one side of the machine to the other, for raising the mould cores from the mould units prior to the halted cones being discharged, and holding same raised while being transferred from one side of the machine to the other, and to provide means for lowering the mould cores after being so transferred. The invention also has for its object to provide improved means for unlocking the mould units and mould cores from each other prior to their transference, and to improved means for reloclring the mould units and mould cores after their transference.

Fig. 18 is a front elevation of a part of the machine adjacent the point where the mould units enter a track, and such view shows in elevation certain parts by which the unit locking levers are controlled.

As shown, the machine comprises the two vertical shafts 1, 1, one at each end of the machine, see Fig. 2, and receiving to and fro, or oscillatory motion through spur wheels 2, 2, and toothed racks 3, 3 on slides 4L, 4, one of the slides being connected by link 5 to an eccentric. or crank pin 6 of a driving wheel 7. The shafts 1, 1, are supported at their lower ends and along'thei-r length by bearing bosses 1, 1 forming part ofthe machine framing. Encircling the shafts are the fixed semi-circular flanges 8, which form part of the inner tracks for the mould units. Extending from flange to flange are L-sec tion rails 9, 9,see Fig. 2,'the rails and flanges forming a continuous track. Parallel with I the rails 9, 9 are further L- section rails 10, 10,

supported by the machine frame members 11, 11, such further rails and the rails 9, 9 forming parallel tracks upon which the mould units travel.

The mould units each comprise a bar 12 of rectangular cross section, in the vertical faces of which mould cavities or recesses are formed so that when two barsare placed side by side and the recesses in one come opposite those in the other, complete mould cavities are formed, see Fig. .5. The mould units are transferred one by one by mechanism hereinafter described, from one parallel track to the other. The mould units are of a length such as to cause them to extend from rail 9 to rail 10, on each side of themachine, and the number of mould units on each side of the machine is such as to completely fill the length of the track on that side, there being the same number of units on one side as on the other side of themachine, see Fig. 2.

Enclosing the shafts 1, 1, are further fixed flanges 1'3, 13 see Fig; 4:, which lie above the flanges 8, 8, and form tracks for supporting the'inner ends of the mould core carrying bars, while transferring same from one side of the machine to the other. There is a core bar for each pair of mould units, and each core bar comprises a hollow rectangular bar 14:, from which depends a plurality'of hollow mould cores 15, see Fig. 5, one for eachmould cavity between the mould unit bars. Each core bar is suspended axially from a cross-' bar 16 so as to be free-to swivel about said bar, when necessary, At each end, each mould unit has .a rod 17, which passes through an opening in the cross-bar and acts as a guide for the cross bar, when moved up and down. A. roller 18 is fitted to each end of the crossbar,,and such rollers, on the cross bar approachingjthe discharge end. of the tracks,engage mechanism by which the core bar is raised to cause its mould cores to lie clear of the mould units, preparatory to the endmost mould unitbeing unlocked and the baked cones discharged therefrom, and also preparatory to the endmost mould unit and core bar being transferred to the entrance end of the tracks on the other side of the machine.

Each core bar is normally held locked to its mould units by a hook-like lever 19, pivotally mounted on the cross bar 16, and engaging a complementary hook-like shoulder 20 on the mould units, springs 21, between the cross bar and core bar, see Fig. 16, allowing the levers to engage and hold the parts together with a slightly yielding pressure.

011 each end of each mould unit are two lugs 22, 22, each of which when the adjacent units lie close together, lies against a like lug on the; next unit, and by means of such lugs and fork-ended levers 23 pivotally mounted on a further lug 24 of the mould unit, the unitsare adapted .to be held firmly one alongside the other, each of the levers 23 normally engaging the lugs 22 under the force of a spring 25 acting as between the lower end of the lever and a bracket 26 below the unit, see Fig. 16. On each mould unit reaching the end of its traverse along one side of the machine, the locking levers 23 of such unit are operated to release the unit by means of cams. One of such cams forms part of a slotted lever 27, see Fig. 16, which by means of a pin 28 in a vertical slide bar 29 moving upwards and entering the inclined part of the slot, moves circular flange 30'surrounding the shaft 1,

against which flange the small roller 23 at the lower endof thelever-23 on the inner end of the mould unit bears, thetwo cams thereby releasing'the endmost unit from the next unit. i

The bar 29 at each end of the machine is raised and lowered at the proper time by inclined track icams 31 on the slides 4, 4, the

bar having a bowl 29 to travel in the cam groove. 1 Y

The raising of the core bars 14, preparatory to unlocking the endmost mould unit to discharge the baked cones, and transfer the mould unit to the other side of the machine, is efliected partly by means of fixed brackets 32, 32, one at each side of each track, and each having an inclined upper part, see Figs. 1 and 6, on to which the rollers 18 of the cross bars passas they reach the end of the traverse of the mould units and core bars, and just after the end core bar has been released from the m'ould'units'by the lower hook-like end of the lever 19 moving .outwards and clear of the hook-like shoulder 20 on the mould unit. The means for effecting mould core bar is effected by the vertical bar 29, at each side of the track having at its top end a plate 33, which on its underside carries a further plate 3 1, normally lying level on its top face with the top horizontal part of the upper face of the adjacent bracket 32. On the cross bar rollers passing on to the plates 34: at each side of the track, the bar 29 is then raised by the inclined cam tracks 31 of the slide 4 immediately below the mould 111111138 on the same side of the machine until "the plate 34 of each bar lies level with the top ,face of a further fixed bracket 35 at one side of the track and with the top face of the flange 13 at the other side of the track. Simultaneously with the arrival of the crossbar 16 at the said raised level, the bar is caught by the mechanism hereafter described, for transferring it to the other side of the machine While being raised and moved forward the end core bar 14; is tilted about its axis, to cause the cores to move clear of the baked cones and facilitate their discharge from the moulds as the mould units are separated. Such tiltlng of the end core bar 18 effected by means of a small bent arm 36 at .broken lines in Fig. 6. The spring 14* acting between the core bar 14 and the cross ,bar 16 assists in returning the cores to the =vertical position, and a roller 1 t on the core bar, meeting the bar 17, limits the return of the core bar.

The means used for releasing the core bars from the mould units consists of a plunger rod 39 at each side of the track and below the bottom ends of which the rollers 18 on the cross bar 16 pass, at which moment the plunger rods are depressed by means of lever arms 10 carried by a cross shaft 41 and by means of a further lever arm 42 on said shaft, which, in turn, receives movement from the mechanism used for transferring the end core-bar to the other side of the machine. To ensure of the levers 19 leaving the shoulders 20 when the core bars are depressed, a spring pressed linger 19 is provided, against which each lever 19 bears and by which it is moved clear of the shoulder 20 as the core.

bar moves forward.

S a pair of long lever arms 43, 44, the lower lever arm 13 being adapted to engage and transfer the endmost mould unit when such unit is timed to be taken to the other side of he machine, and the upper lever arm 44 being adapted to engage and transfer the endmost core bar and cross bar when requiring to be taken to the other side of the machine.

As shown by the broken lines in Fig. 1, the inner end of the mould unit, while being transferred, is carried upon the track plate 8, and

the inner end of the cross bar 16 is carried by i the flange 13. The outer end of the mould unit is carried by the lever arm l3, which is furnished with a bracket 45 with bevelled cross head, upon which the mould unit rests, see Figs. 14 and 15. a

Each mould unit, between the mould cavities, is hollow, forming flue passages forthe heating medium, and the front and rear walls of the passages, are used to effect the transference of the units. That is to say, pivotally mounted on one side of the lever arm 43isa metal bar 46 with inclined upper extremity, which is normally held raised by a springl'l. On the lever arm 43 moving aorossthe machine, the inclined extremity of the bar 46' meets the outer lower edge of the mould unit and then moves down to pass below said edge, after which, on coming below the unit, it moves up again, and thereby becomes engaged with the unit. On the other side of the lever arm 43 is a further pivotally mounted and spring-held bar 18, with bent upper end extending towards the bar 46, and the nose of the bar 4:8 then lying close to the mould unit, which is thereby held relatively to the lever arm 43, and is ready to be transferred to the other side of themachine. On such transfer taking place, the plate 46 pushes against the unit which is thereby caused to move with the lever arm to the other side of the machine. On the bevelled edge of the upper end of the bar 4-8 meeting the last transferred mould unit, it is depressed, and held depressed by the final movement of the mould then carried by the lever arm. On the lever arm then making its return or idle movement, the inclined upper endof the bar l6 meetsthe other lower edge of the mould unit, and owing to the unit being then held against return movement, as hereinafter explained, slips below the said edge, the bar 48 by that time be ing below the mould unit last transferred, see Fig. 14;, when the lever arm is free to return to the starting point to engage and transfer the next mould unit, the bevelled upper end of the bar 46 engaging such next unit by passing below it and upwards into the flue passage.

The bars 16, 418 are held to the lever arm 4-3 by links 49, which are pivoted to a plate 50 clamped to the lever arm. The upward movements of the bars 46, 48 are limited by pins 51.

Each cross bar and core bar is transferred simultaneously with a mould unit, by the lever arm 14, whichhas a hook-like bracket 52 at its free end, see Figs. 12 and 13, with which the hook-like part 14 of the core bar engages when the lever arm moves to engage the cross bar. On the lever arm 44: are pivotally mounted-gravity fed'ba-rs53, 54 the lower endof the bar 53 being inclined, in order that.- it

may rideover thecrossbar, when moving'to engage same;

The bar 54 at its lower end extendstowards and away from the bar. 53 andthe front and rear edges of such end are bevelled. As the lever arm 44 moves-to engage a crossbar, the bar 53 rides over and then drops behind-- it,

\ while the lower end of the bar 54'lies opposite the cross bar, see Fig. 11. The lever arm isthen moved totransfer the cross bar and with it the core bar to the other side ofthemachine, on reaching which, the bar 54 meets and rides on to the preceding cross bar, and in such po.-

sition allows the cross bar, then being transferred,tto pass into the correct position-for subse uent lowerin and" 3388111 forward.

Onthe lever arm 44 making its return movement, the bar 54 rides off'the last transferred cross bar, and resumes its original position, ready to co-operate with the bar 53 1n engaging and transferring the next cross bar. As the lever arm 44 moves back to its original position, a projection 55 on the lever arm meets and presses against the lever arm 42 on the cross shaft 41 and depresses the plunger rods 39 by which the'cross bars prior to running on to the inclined brackets 32' are pressed down against the springs 21 to release the latching levers19, which by means of the finger 19a previously described are moved clear of the shoulders 20-to unlatch-the core bars from the mould units.

reaching the other side of the machine, that is, on reaching the entrance of a track, a hook- 56 is provided, under the bevelled end of which the stud of the roller of the mould unit passes and which engages-the roller stud toprevent its-backward movement.

On reaching-the opposite side of the machine, the roller 18 on the cross bar comes to rest upon plates carried at the upper endsof the link bars, designed to be lowered until the core bar and-its-cores engage the mould.

Alongside the bar 59'is a-fixed slotted plate 61, the slot in which has two parallel vertical.

parts and two parallel inclined parts, produced by an island piece 61*. Inthe-slot works a pin 62 carriedby a-f'urtherlink bar 63 pivoted byfshort links 64, 64 to'the. link.

bar 57. I

To the upper end of eachcambar-59. is

fitted a horizontal plate 65which:overhangs2 To prevent themould units rebounding or moving back on the cross bar; roller 18 when such rollerzis.

restingupon the plate .58: (see Figs. 8 and 9)- so that in lowering. the link bars 57', 63 by means ofthecam bar 59 to lower the cross bar, the plates 58,. 65 compel the cross bar rollers to move down also. On the core bar reachingits lowest position, i. e. resting upon the mould units the cam bars-59 commence to rise up again, the cam 31 having then reversed its direction, and in order to causethe plates 58 of the link bars 57 to pass. from beneath the crossbar rollers 18before rising, so as not again to-raise thecore bar, the pin 62 in the cam slots 61b of the plates 61 causes the plates 58 to be drawn-from 'below-the rollers (to the right in Fig. 8) during the latter portion of the'descent' of the cam barsas-shown-in Fig. 1,. and owing to the cameslot 610. and to ascend in a path in which they remain clear of: the rollers, and finally'resume their original positions, shown in-Figs. 8 and 9, immediatelyibehind the cam bars; and level withthe fixed parts of the 7 track orbracket13 on to which the rollers run when'transfer-red from the otherside of the.

machine. I

The endmost mould unit, after meeting the last transferred mould unit, is locked to such unit. by'means of the levers 23-and lugs 22. The levers: are moved and held out of en.- gagement with the lugs 22 during the latter part of their being carried from one track tothe other anduntil the mould units are in correct position for relocking by means of. cams, one of which is in the form of a swellingo30 'on thejfixed flange 30 and the other in the form of a flat-sidedmetal bar 66 slidably mounted in abracket 67 against the resistance of aspring 68, see Figs. 17 and 18. As a mould unit passes from one side ofv the machine to the other, the lower end of the lever 23 at the inner end of the unit,.engages the cam swelling, 30 on the flange 30, and thereby holds the forked'end' of the lever clear, of the lugs 22 on the unit until. the unit is in contact with the prescedingunit. Similarly, the lower end of the lever 23at the outer end of the mouldunit, meets and presses against and travels. over the faceof the bar 66, and the forked end of the-lever23v is thus held; clear of the lugs 22 on the units. WVhen, however, the next mould. unit is-broughtround to that part of the machine, the previouslyubrought unit is moved along the track to. a position where the inner roller 23 leaves the cam swelling 30 so that the inner lever 23 looks the units together. Asthe radial arm 43 now commences its return movement (to the right in- Fig; 18) a-plate 69 thereon meets a trip lever 7 0 on a bell-crank lever 71, see Figs. 16, 17

and 18, and moves such lever 71 aboutits' pivot, and by means of the rod 72 retracts the bar 66 out of contact withithe'roller 23 so that the lever 23 may regain the locking position. The spring 68 serves normally to keep the bar 66 in position for actuating the levers 23, although it cannot regain that position to unlock the units once the mould unit has passed. The trip lever 70 and its spring 7 0 permit the arm 43 to pass in one direction, i. e. the mould transferring direc tion, without influencing the bar 66, see Fig. 18 The new batter is delivered to the mould units immediately they are locked together, and before the mould core bars are lowered.

After a core bar has been lowered on to the mould units, it passes forward along with them and becomes relocked to the mould units by means of the levers 19 and shoulders 20, the rollers of the cross bar coming below a pair of presser bars 73, which are operated to depress the cross bars against the springs 21, there then being no support under the rollers 18, by a cam swelling on a disc 74L on the adjacent vertical shaft 1, and by levers 75 on a cross shaft 76 which also carries lever arms 77 connected at their outer ends to the presesr bars 7 3. The lever arm 75 has a bowl 75* to engage the cam, and is kept in engagement by a spring 78. As the cam 74 rotates, the levers 7 5 and 77 are rocked and the presser bars 73 depressed, whereupon the levers 19 fall by gravity into the locking position.

The mechanism for delivering and controlling the batter comprises the pivotally mounted feed pipes 79 which are moved clear of the incoming core bars and moulds by means of the reciprocating slides 80 connected to the slides at, a pin 80 on the bar 80 working in a slotted arm 79'" on the axis of the pivotally mounted feed pipes 7 9. The mould units are advanced along the tracks step-bystep by the pawls 81 on the pivoted lever 82, which is connected by the rod 83 to further pivoted arms 84, adapted to be moved about their pivots by the slides i, upstanding projections 85 on the slides l engaging rollers on the lower ends of the levers 84. The pawls 81 are timed to engage the last transferred mould unit just prior to the radial arm 43 commencing its return movement.

The machine illustrated is fitted with fast and loose belt pulleys 86 to receive power, which is transmitted by shaft 87, bevel gears 88 and pinion 89 to the wheel 7.

The cones are baked whilst the mould units pass along the tracks over gas burners 90 supplied with gas from pipe 87 along the sides of the machine.

It will be understood especially from a consideration of Fig. 2, that the mechanism at one end of each track of the machine is a replica of the mechanism at the end of the track diagonally opposite, or that one half of the machine, taken to right or left of a line drawn through the shafts 1, 1 is a duplicate of the other half, the inlet end of one 1.
