- the channel l5 at the rear end communicates with the cylinder 8' and its forward end opens toward the die I.
- the forward end of the channel is smaller than the rear end and the walls of the channel converge from the rear end toward the forward end so that the soap material which is forced through the die will be compressed before it is extruded from the forward open end of the die.

- the cylindrical member l6 extends to the forward open end of the die and it is by means of this cylindrical member that an aperture in the stream of soap being extruded will be made which is annular in cross section.

- the motors 2 and 3 are driven at such speeds that the rate at which each stream of soap is being extruded through the complementary dies wil be substantially equal. This permits the-soap streams to be extruded from the dies at the same time and the ends of the streams to reach the center of the space between the die at substantially the same time after which the streams will become interfitted. As there is continuous movement of the streams in opposite directions, the interfitting will continue until the end of each stream approaches the die opposite the die from which it is extruded.
- the interfitting portions of the two streams of soap can be severed from the streams and thus produce a cake of soap which has embodied therein and extending completely therethrough an indicia of a color contrasting to that of the cake body.
- the soap material being extruded is plastic in form, the streams will nevertheless interfit readily since the unsupported portions of the streams, before interfitting takes place, are so short that there will be no harmful sagging of the streams prior to interfitting.

Referring to the drawings in detail, the improved apparatus shown for carrying out my improved method of soap cake manufacture has a frame :1 upon the opposite ends of which are mounted electric motors 2 and 3 Which are of the variable speed type, the varying of the speeds of the motors, being under the control of suitable levers l :and 5 on the exterior of leg compartments fi and! atopposit'e ends of the frame. On the frame adjacent the motor 2 is mounted a casing 8 having a cylindrical bore 8 in which is a screw 9 driven :by said (motor 2. There'is also :shown a hopper Id wherebysoap material in suitable form may be fed into the cylinder of the easing and forced out-its-forward 'end by rotation of the screw 8.. In a-similar manner there is associated with the :motor 3 a casing l I provided with acy-l-indrical bore H having mounted therein a screw 12 which is driven by the motor 3. There is also provided a hopper l3 for feeding soap material to the cylinder 1to=be forced out its forward end by the screw [2. Soap material can be fed to the hoppersin any suitable manner, as by means of conduits. The cylinders" andthe screw therein are arranged :to handle a soap imaterial tor the body portion of the finished cake of soap, whereas the. cylinder 11' and the screw [2 are arranged to handle a soap material for the indicia which is to be: embodied in the main body of the soap cakasaid soap material to be of contra-sting color with respect to the cake body. As an example of the contrasting colors, the soap loodyfmayrbe made of white soapnmaterial vand the indicia may be made of green colored soap material. The particular indicia which is illustrated as being embodied in the soap cake is the letter 0, but it is to be understood that other letters, monograms, emblems, words, trade-marks, etc., may be embodied in the cake of soap in a color which is contrasting to the color of the body of said cake.
The casings 8 and I l are aligned and in spaced relation with the forward ends of the cylinder in each casing opposed to each other. On the forward end of the casing 8 at the open end of its cylinder, there is mounted an extruding die indicated by the letter B and on the forward end of the casing ll there is an extruding die I. These dies are bolted to the ends of the casings by suitable stud bolts l4 so that they may be readily removed and replaced by other dies when dilferent indicia is to be embodied in the cake or the general outline of the cake changed, as for example, from a rectangular shape to a round shape.
The dies B and I are shown in detail in Figures 3, 4 and 5 and reference is now made to these figures. The die B, from which the main body of soap is to be made, has a rectangular shaped channel l5 therethrough and is employed to make a rectangular shaped soap cake body. The channel l5 at the rear end communicates with the cylinder 8' and its forward end opens toward the die I. The forward end of the channel is smaller than the rear end and the walls of the channel converge from the rear end toward the forward end so that the soap material which is forced through the die will be compressed before it is extruded from the forward open end of the die. Compressing, of course, will be brought about by the action of the screw 9 continuously forcing soap material into and through the channel l5. Centrally positioned within the channel is a hollow cylindrical member l6 provided with a desired wall thickness and being longitudinally arranged in the channel. This cylinder is supported in the central part of the channel by spokes I! which are relatively thin so that they will not obstruct flow of the soap material and readily permit the soap to flow around the spokes and. become united under the compressing action before the soap is extruded from the open forward end of the die. The cylindrical member l6 extends to the forward open end of the die and it is by means of this cylindrical member that an aperture in the stream of soap being extruded will be made which is annular in cross section. When the material of contrasting color is received in this annular aperture the letter 0 will result which is the letter being used as an illustration in the particular embodiment shown. With the die 3" arranged, as shown, it is seen that the stream of soap material being extruded from the forward open end of the die will have a square outer perimeter and an annular aperture extending in a longitudinal direction.
The die I is formed to be complementary to the die B. This die I is therefore shaped to form a hollow cylindrical stream of soap which is of such cross section that it can fit into the annular aperture in the stream of soap being extruded through the die B. To make the cylindrical stream of soap, the die is formed with a channel I8 of circular cross section, the rear end of which communicates with the cylinder in the casing II and the forward open end thereof be opposite the end of the cylindrical member ll; of the die B. The diameter of the channel l8 at its forward open end is slightly less than the external diameter of the cylindrical member It in the die B and the axis of the open end of the channel I8 is so positioned as to coincide with the axis of the cylindrical member I6 of die B. The rear end of the channel I8 is flared so as to readily receive the soap material from the cylinder ll and .to also compress the soap' material as it is forced into the channel by the screw l2. Within the channel I8 is a solid cylindrical member I 9 which is held therein by spokes 20. The axis of this cylindrical member coincides with the axis of the channel and the external diameter of the cylindrical member at the forward open end of the channel is slightly larger than the diameter of the hollow cylindrical member IS in the die B. Thus it is seen that as the soap is extruded through the channel I8 it will come out of the die in the form of a cylindrical tube and will be of such size as to fit within the annular aperture of the stream of soap material coming from the die B. Therear end of the solid cylindrical member [9 tapers to a substantial point at the rear end of the channel l8, thus aiding in compressing soap material in the channel as the material is forced therein by the screw [2.
Theopen ends of the complementary dies B and I are spaced apart a distance which is slightly greater'than the thickness of the soap cake which is to be produced. In making the soap cake the motors 2 and 3 are driven at such speeds that the rate at which each stream of soap is being extruded through the complementary dies wil be substantially equal. This permits the-soap streams to be extruded from the dies at the same time and the ends of the streams to reach the center of the space between the die at substantially the same time after which the streams will become interfitted. As there is continuous movement of the streams in opposite directions, the interfitting will continue until the end of each stream approaches the die opposite the die from which it is extruded. At this time the interfitting portions of the two streams of soap can be severed from the streams and thus produce a cake of soap which has embodied therein and extending completely therethrough an indicia of a color contrasting to that of the cake body. Although the soap material being extruded is plastic in form, the streams will nevertheless interfit readily since the unsupported portions of the streams, before interfitting takes place, are so short that there will be no harmful sagging of the streams prior to interfitting. The cake of soap being made will probably not be thicker than an inch and a half, thus it is seen the greatest unsupported length of extruded soap will not be greater than approximately threefourths of an inch.
Although I prefer to cause the streams of soap being extruded to move simultaneously from the dies at the same rate of speed, it is possible to first cause one stream to be extruded and then the other stream to be extruded, provided, of course, the thickness of the soap cake to be formed and the soap material is such that no such sagging will take place that the two streams cannot be caused to readily interfit. Such a procedure in obtaining interfitting of the two streams is within the scope of my invention.
The mechanism for cutting the streams to form the soap cake will now be described and reference is made to Figures 1, 6, 7 and 9. The
anemone andso related-tothe dies that when'the. shaft 2i is rotatedthe blade will passalong. the forward face of the die B andrthe-blade- 26 will pass along the face of the die I, thereby performing cutting of thetwostreams-of material being extruded-bythe dies. I he cutting-of each stream will occur at the faoe surfaceofthe die.
The shaft 2 lis arrangedto be-driven by suitable gearing 21 from a motor shaft- 2B of anelec-- tric motor 2 9-. As shown. in-the schematicview of Figure 9 this motor shaft 28 has associated therewith a brake 30 which: is normally: held applied-by a spring 31 and: released: by a solenoid or magnet S. Associated V with the line 32 leadingto-themotor 2 9 isa timer; a main switch for the motor and: also a switch for the solenoid S of the brake which is connectedtothe line by conductors 33-. The timer andthe two switches are all: enclosed in-a single-box generally indicated by the letter T. Thetimer at periodic intervals will cause a closing.- of: the main circuit of the motor and-a simultaneous closing of the circuit for the solenoid. Thus the brake 5t willbe released and the-motorstarted. Starting of the motor will=swing the cutting blades 25 and it through one revolution and these blades will cut the two streams of soap-material being extruded by, the-dies. Thetimerislsdarranged that it will cause abreaking-of the circuit to motor 29: and tothesolenoid o-f thebrake when the motor has rotatedthelbladesthrough the one revolution; Therewillthen be are-application of the brake and thestopping of themotorat the proper time. Thetimerswitch is-socoordinated with the speed of the extruded streams ofsoap material that the bladeswill be operated when the end of each stream of extruded materialsubstantially reachesthe opposed 'die; this condition being illustrated in Figure 3. Undersuch circumstanceseach blade will only be required to cut one stream, the blade- 25 c-utting the stream from the die B andthe'blade 26= cutting; the stream from thedie- I 3 The end surface of the die adjacent thetops thereof are-beveled so that the blades, when-rotated, will be guided to move along the end surfaces of the diesso as to make aclean shearing out.
It is possible-that when theinterfittedportions of the streams arecut from the streams by the blades, the cake of soap will not freely drop-out from the streams by gravity; In order to-insure that this will be done, -there-isassociated with the blades a kick-out paddle. This paddle extends from a collar 35- loosely-mounted on the shaft 2i between the blade collars 23 and 24. The blade collars are provided with-lugsSGwhich fit into slots t'l-inthecollar-fi. The-slots-3-I are of considerably greater arcuatelength than the lugs to thusprovide a lost motionarrangement between thebladesand the paddle. A= hair pin type of spring 3B is' connected between each lug 36 and the paddle collar-35;as-best shown in Figures 8and-9.-- Thesesprings bias-the-paddle so that it will be normally insubstantially; the same plane asthe blades (see- Figure-- 8), yet will perm-it the blades tomoverelativelytothe paddle by a compressing of the hair: pin springs: 13? this. arrangement, when. the blades are: operated to perform a. cutting: operation, the paddle: will be moved along with: the..b1ades'= towhere itengages the top surface of the interfitted portions of the streams where it will remain: while the blades move relatively thereto .and'. out: the streams.

When the beam between the photo-electric tubes is broken the timer will close the switches so that the brake will be released and the blades given one rotation to perform the cutting operation. When this one rotation is accomplished the timer will permit the opening of the switches, thereby reapplying the brake and stopping the motor. When th interfitted portions of the streams of material have been severed and kicked out the beam will no longer be broken and thus the cycle will be set up for the next cutting operation.
