This invention relates to improvements in machines for pressing plastic material, such as soap, into cake form and is particularly directedfto a type of machine having a rotary carrier providing'mold openings, which car- Y rier is serially stationed by perlodlc rotation for the various steps in the handling of the material, such as thc loading of the carrier, cooperative positioning of the loaded openings relative to pressing dies to form a pressing chamber and discharging of the finished product.

It is therefore an object of this invention to provide an improved mechanism relative to 4a rotary carrier for cooperation with the mold openings thereof at a primary or loading station, for feeding the crude plastic cakes into the rotary carrier.

Another object is to provide an improved mechanism for actuating pressing dies, this mechanism synchronizing with the movement of the carrier and adapted to cooperate'there- ,with at an advanced or loaded station to press the soap within the mold apertures, to provide a mechanism incorporated in the die movement for permitting the proper compressibility in die engagement to govern the pressure applied to the soap, and to further provide die operating means for imparting successive pressures to each bar of soap in a single cycle of movement of the means.

Another object is to provide a mechanism relative to a further advanced or discharge station of the carrier, for moving the discharged or finished product from a point adjacent the carrier to a suitable conveyor.

Another object is to provide a machine of this type which performs each of the serially arranged foregoing .operations on a plurality 0 of the articles simultaneously, thereby increasing the output of the machine.

Another object is to provide a die pressing mechanism which operates a plurality of dies simultaneously and in which the respective dies are cushioned independently so that they automatically adjust to accommodate for variations in the quantity of material upon which they act and thereby produce articles which are uniformly pressed and sharply contoured.

Figure l0 is a perspective View of the discharge trough removed from thc machine.

The crude blocks of soap a re fed into the machine over a dual conveyor, the respective belts of the conveyor moved by an intermittent motion device for feeding two cakes of i soap into the mechanism for each quarter turn thereof and each movement of the various mechanisms.

The conveyor in its intermittent motion moves the blocks of soap into conduitsin the path of reciprocating hfter plungers which elevate the soap to a plane for engagement b horizontally moving feeder plungers at whic time a pair of mold openings in the rotar carrier frame is in alignment'- with the fee in plungers. l L

pon retraction of the feeding plungers the rotary carrier frame is rotated a quarter vof a turn by a Geneva gear movement which brings the loaded openings in alignment with s pairs of dies coming in from the respective opposite sidesthereof, these dies beiner operated from a common eccentric plate and pressing the soap in the desired shape within the mold openings. Thereupon the rotary carrier frame is turned a quarter of a turn and the pressed, bars of soap are brought into' alignmentwith ejector' plungers which push them laterally from the carrier frame into al discharge trough. A feed slide moving through the discharge trough pushes the finished products through the trough and discharges them laterally of the machine.

r Every time the fully loaded carrier frame is moved a qua-rter of a turn, three distinct functions thereupon take place; two bars of soap are ejected, two are pressed, and two are fed thereinto so that it may be said that vupon each quarter turn of the carrier frame all mechanisms of the machine perform their respective functions.

Referring to the drawings illustrating an embodiment of the mechanism performing in the above described manner, the details thereof are as follows:

The frame of the machine, indicated at 11 is cast hollow and providesa body portion, and an overhanging forward end, the throat formed between the overhanging portion and the body being the location where the various operations are performed on the article.

The soap is fed into the machine in a pliable condition and in this instance is cut in cruderectangular blocks indicated in the drawings at 12. These blocks are fed in rows on conveyor beltsv13 mounted in a rack 14, this rack being suspended from the overhanging end of the frames by means of a bracket 15 bolted to the underside thereof, and at the other or outer end being mounted on standards v16.

Angle iron lengths 17-17, are secured to `'the bracket 15 at their inner ends, and at their outer ends carry a journal frame 18 cross shaft 25 journaled in the side anges 26 of the bracket 15.

The conveyor belts passing around the re- I spective aligned pulleys at each end of the the top of the conveyor frame, pass alon frame, the angle iron len s bein secured flush with the to `of the bracket. s shown in Figures 2 an 9, the respective conveyor belts are slightly spaced apart and a parti-v ing a vertical passageway 30 at the discharge ends of each conveyor' belt. The conduit passageways are open at the base ends and enter horizontal passageway portions 31 which are adapted to be traversed by plungers moving the block'of soap into the mold openings of the carrier. The vertical conduit passagef ways are traversedby plungers 32 secured to a slide 33 vertically reciprocable ina slideway 34`formed in a casing 35 bolted to the body of the frame 11.

A two-piece take-off late 36 is secured to the top face of the brac et 15. at the conduit endofthe conveyor frame, one element 37 of the plate being adjustable toward and from the lifter plungers 32-32 in order to provide that the bars of soap being displaced from the conveyor belts and from the plate 36 are'disposed in proper alignment for engagement by the lifter plungers.

The conveyor belts 13 are intermittently fed by means of a pawl and ratchet mechanism. A bell crank lever 38 is loosely mounted on the outer end of the inner pulley shaft 25, one arm of the bell crank lever carrying a pawl 39 spring urged into engagement with the teeth of a ratchet wheel 40 secured to the shaft 25. The other arm 41 of the lever is provided wilh a series of apertures' 42 for adjustable connection to a link 43, the opposite end of which is pivotally connected to one end of a lever 44 fulcrumed on a bearing standard 45 secured to the frame 11, the opposite end of the fulcrum'ed lever being connected to an eccentric movement by means of a link 46. The link 46 is connected for actuation from the eccentric movement by virtue of its connection to a depending lug 47 formed on the lower end of a die crank lever 48 (see later description) in direct connection with an eccentric -pin 48a providedon a flywheel 49 secured to the main drive shaft 50. of the machine.

The means for reci rocating v the lifter plungers 32 is of the fo lowing nature;

A pitman 51 is connected at its lower end to the wrist pin of the slide 33 and at its upper end to the crank in of the crank wheel 52 secured to the orward end of a shaft 53, this crank mechanism being housed in the before-mentioned casingv 35. The shaft is driven by meansl of a gear 55 keyed thereto and in mesh with a companion gear 56 keyed to a shaft 57 journalled in the respective end walls of the body of the frame 11. A spiral gear 58 is keyed to the shaft 57 toward the rear end ofthe machine, and is in mesh with a companion spiral gear 60 keyed to the main drive shaft 50 which extends crosswise of the frame and is suitably journalled in the side walls thereof.

The rotary carrier 61 is secured to the end of a shaft 62 journalled longitudinally of the body portion of the frame 11, the rotary carrier. 61 being disposed for rotation in the vertical plane with pairs of mold openings 63 therein moving into periodic alignment with the horizontal discharge passageways in the conduits. As shown in Figure 4, the rotary carrier has the pairs of mold openings 63 formed laterally therethrough, the openings,

regarded in pairs, being disposed at right angles to each other, in the same relation to the axis of rotation andalong each side of the substantially square rotary carrier.

Intermittent motion is imparted to the rotary carrier for causingzeach pair of mold openings to be disposed adjacent the loading conduits upon 90 of carrier revolution. This movement is imparted by means of a Geneva gear movement at the opposite end of-the machine, the slotted follower or star wheel 64 of the Geneva gear movement providing four points and being keyed to the outer end of the rotary carrier driving shaft, and the driver 65 of the movement providing a pair of diametrically disposed rollers 66 cooperating with the slots of the iirst mentioned element to impart a quarter turn to the rotary carrier driving shaft upon a half turn of the driver of the Geneva gear, this driver 65 being loosely mounted on the outer end of the before-mentioned lifting element driving shaft 59.

A collar 67 is keyed to the shaft adjacent the Geneva gear driver and provides a series of apertures therethrough selectively traversible -by screws 68 which connect the keyed driving collar 67 to the loosely mounted driver 65. This adjustment is provided in order to vary the movement of the rotary carrier relative to the movement of the pressing dies as will be hereinafter described.

In order to move the elevated bars of soap from the con duits into the aligned mold openings. of the rotary carrier, a loading device is provided of the following nature:

A slide 69 is horizontally slidably mounted ably secured therein by means of set screws 74, these rods traversing the discharge pas` sageways ofthe conduits. The rods carry shoes at their outer ends having wide faces for engagement with the bars of soap.

A plate 76 is provided extending across behind the pairs of mold openings and adjustably secured to the main frame by a bracket 77, this plate limiting loading movement of the bars into the mold openings. A pair of ejector rods 78 is provided at the upper side of the horizontally movable pusher yoke element 72 for the purpose of discharging the finished product from the upwardly disposed mold openings. The yoke element thus loads and unloads the carrier in the same movement and the dies act at the side or intermediate position of the mold openings. l

The slide 69 is reciprocated by means of a bell crank lever 80 journalled in the overhanging portion of the frame above the slide, one arm of the bell crank lever carrying a wrist pin 81 having a headed end engaged between a pair of spaced bosses 82 cast on the slide. The upper end of the bell crank lever extends through a slot in the top of the frame and is connected to one end of a link 83, the other end of the link carrying a yoke 84 adjustable thereon, the arms of the yoke 84 being pivotally connected to the eccentric pin 85 of an eccentric plate 86 keyed to a rocker shaft 87 disposed crosswise to the frame and journalled in its respective side walls. The rocker shaft 87 is oscillated by means of the crank lever 48 as will be described in the description of the mechanism for operating the die.

The before-mentioned crank lever 48 as described, has its lower end connected to the crank pin 48a of the flywheel 49 and its upper end is connected to a cross pin 88 extending between and journalled in a pair of dieoperating spaced toggle plates 89 keyed to the rocker shaft 87 on the outer end thereof exteriorly of the frame. The toggle plates also carry a pair of cross pins 90 diametrically related relative to the rocker shaft, the connection of the crank lever 48 to its cross pin being toward the rear of these diametrically related pins.

A pair of pitmen, 91, 92, forward die-operating and rear die-operating respectively, have their. adjacent ends connected to the diametrically related cross pins. The lower pitman 92 is comparatively short in length and has its outer -end connected to the wrist pin 93 of a horizontally mounted slide 94. The slide is mounted on the side wall of the llO i frame in a slideway and is maintained theref in by means of a gib plate 95 and overhanging plate 96. i

One end of the slide 94 disposed toward the` rotary carrier is provided withI a headed portion 97 providing an attaching face for a pair of dies 98-98, these dies in their reciprocation being in perfect alignment with a pairof the mold openings 93 when the rotary carrier is at rest. The upper or long pitman 91 is connected .at its outer end to the wrist pin 99 of a forward die-carrylng slide 100, this slide being maintained in a slideway parallel with the rear die sl1de and in the ovcrhanging portion of the frameby means of av gib plate 101 and overhanging plate 102.

Forward dies 10S-103 are mounted on the l headed ends. of individual rods- 104-104 slid'eably mounted parallel with and in the slide. Thev portion of each slide rod adjacent the head thereof is square at at 105, moving in a square channel in the side face of the slide and a plate 106 is attached to the p side of the slide by means of screws vfor maintaining the slide rods against rotatlon within the channels.

The rods 104 pass through respective lateral openings 107 in the slide and a pair of washers 108 is provided on each rod, one washer being disposed against a shoulder formed by the termination of the squared portion and the other being slideably disposed against the opposing Wall of the lateral opening.

A coil spring 109 is d1sposed W1th1n each lateral opening under compression between the washers. 10S- 108. A pair of adjustment nuts 110 is screwed onto the forward end of each rod, t-hese nuts engaging the respective side walls of a second pair of openings 111 for limiting the action of the compress-ed springs, the nut housing openings 111 being of sufficient dimension to allow movement of the nuts relative thereto under lspring compression. The springs compress under die engagement and cushion the engagement of the dies with the cakes of soap being pressed. The dies are easily removable from the respective slide heads and may be of any desired formation.

The pairs of dies as mounted on the re' msaass sure is alwaysimparted to each -cake suf-- cient to form and'pack the material.

The toggle plates 89 are moved by means of the crank lever, and in combinatlon with the pitmen or toggle levers 91, 92 impart great force to the dies. The movement of the diametrically related pins and the swing of the eccentric plate is past dead center and to a position shown in dotted lines in Fi ure 6, the point of greatest pressure being in icated in full lines in this View.

This movement of the toggle elements past dead center; imparts a double die pressing action on each pair of cakes, there bein a slight retraction of the dies in the perio of movement past dead center. This double action insures a Vsolidly pressed article with the material permanently set, the slight retraction permitting any air to escape which might be trapped between the dies. There is also a longer period over which pressure is being exerted on the soap, this aiding in the permanent formation of the finished roduct.

The third step or discharging operation is performed on the pressed bars of soap after they are moved a quarter turn from the pressing position. The before-mentioned soap discharging rods 78 have shoes 112 on their outer ends and move into engagement with the pressed bars of soap resting within the mold openings as the previously described loading operation is being performed by the lower pusher rods 7 3.

As shown in Figures 4, 7, and 10, a trough 113' extends latera ly of the machine from a point just in back of the upper portion of the rotary carrier, this trough 113- being cut away adjacent the mold openings as at 114 and being supported on a standard y115 adjustably secured to the side of the casing 35. The standard is vertically adjustable so as lo correctly align the base of the trough with the base of the mold openings as shown in Figure 7. The trough is also adjustable as ,to width (see Figure 10) by means of a slotted connection 116 of the side wall thereof relative to the base, and the trough is adjustable relative to the carrier by means of a slotted connection 117 to the standard.

A pusher blade 118 extends vertically into the trough and is movable longitudinally thereof from a point beyond the cakes of soap as pushed into the trough to slide them through the trough to any sort of a conveyor extending from the machine. The blade 118 Vis secured to a slide 119 by means of a bracket 120, the slide having its top and bottom edges longitudinallyslotted as at 121 for engagement with top and bottom rails 122, 123, these rails being secured to brackets 124 attached to the frame.

A link 125 is connected to the wrist pin 126 of the slide 119 and to a lever 127 secured to a stub shaft 128 journalled in a bearing .129 secured to the side face of the frame. The opposite end ofthe stub shaft 128 carries a lever 130 having its grooved swinging end 131 engaged `by the eccentric roller 132 of a rotary clement 133 pinned to the end of the shaft 53. i

The shaft 50 is driven by means of a driving pulley- 134 loosely mounted thereon and a clutch 135 for connecting the pulley to the shaft, this clutch being controlled by means of a lever 13G fnlcruincd on a bracket 137. The handle extends to the intake end of the machine. The lever connects to a translatable clutch member 138 actuating the clutch lever 139.

A detailed description of the operation of the machine follows, this description following a pair of the cakes of soap through the machine and describing the operations. as they are performed successively on the cakes. It will be understood that the mechanisms are acting upon three sets of cakes simultaneously, that is to say, a pair is being fed into the machine, a pair being pressed, and a pair discharged, these three operations being performed each time the rotary carrier is moved a quarter of a turn.

The blocks of material 12 are fed into the lower end of the intake conduit 29 by means of the intermittently actuated conveyor belts 13. As the blocksare displaced from the plate 36 at the end of the conveyor belts, they are engaged by the upwardly moving lifter plungers 32 and are elevated to a plane within the conduit which is in alignment with a pair of mold openings in the rotary carrier, which may be described as in a loading or lower position.

At the time the blocks are brought into this alignment, the pusher rods 73 for loading the carrier come into engagement with the blocks of soap and move them horizontally into the registering mold openings. (It is simultaneously with this loading movement of these plungers that the three operations are performed on'the cakes of soap within a fully loaded carrier.)

As soon as the yoke carrying the loading pusher rods has moved back from the rotary carrier, a quarter turn is imparted to the rotary carrier and the described loaded mold openings are brought into alignment with the incoming dies.

An adjustment is provided as described, relative to the Geneva movement for causing the rotary carrier to receive motion just at the time that the dies are passing out of the respect-ive sides of the mold openings. This close synchronism provides that the soap is effectively stripped from the dies and is left in the mold openings. The soap will normally adhere to the side of the mold openings except in some cases where the quality of the material is not conducive to this adhesion.

After the dies have retracted sutliciently to clear the rotary carrier, another full quarter turn being imparted, the pressed bars of soap yare then disposed at the upper side of the carrier and in alignment with the discharge pusher rods 78. These rods pass entirely through the carrier and move the soap laterally therefrom into the discharge trough or channel 113, the pusher rods then being retracted to permit the ensuing quarter turn of the carrier lto be made.

Intermediate of the discharging of the pressed soap a movement is imparted to the pusher blade 118 in the trough to move the bars of soap laterally from the machine, the pusher blade moving back in time to leave the space clear for the next discharge. Any sort of traveling arrangement may be provided at the end of the trough for receiving the pressed bars of soap.
