Application led February 17, 1910. Serial No. 544,367..

To all whom 'it may concern:

Be it known that I, JAMES A. KEYES, a citizen of the United States, and resident of the city, county, and State o f New York, have made a certain new and useful Invention Relating to Soap-Presses, of which the following is a specification, taken in connection with the accompanying drawings.

This invention relates to soap presses and relates especially to duplex soap presses which may have a single feed and a distributing plunger die coperating alternately'wlth two rear dies and die boxes, there being double delivery devices for discharging the completed cakes of soap or other generally similar material.

Inthe accompanying drawings showing in a somewhat diagrammatic way an illustrative embodiment of the invention, Figure 1 is a plan view. Fig. 2 is a longitudinal vertical section. Fig. 3 is a transverse vertical section. Fig. 4 is an enlarged plan view, parts being omitted; and Fig. 5 is an enlarged detail view showing the plunger slide and its cams.

In the illustrative embodiment of this invention shown in the drawings, a heavy frame may be provided, composed of suitable members, such as 3, 4, 41 and have secured thereto a suitable table 36 over which the soap blanks and completed cakes are fed.

The machine may be operated by the heavy pulley 1 mounted on the shaft 2 in suitable bearings 97 in the frame and Carrying a suitable crank 6. This crank may be connected with the plunger slide 10 by a suitable connector 5 which may be provided with the head 7 engaging the crank 6 and with the head 8 engaging the pin 9 in the plunger slide. This plunger slide, as is shown in Figs. 2 and 3, may be provided with the inclined upper faces 7 6 coperating with the guides 77 secured to the frame members 3, 4 so as to rigidly support this plunger slide as it is reciprocated by the crank. As shown in Figs. 2 and 5, the slide may carry a suitable head 74 on which the solid plunger die faces 68, 69 may be se cured in any desired way as by the bolts indicated. This head my be removably secured Vto the slide and given the desired rigidity by providing it with a reduced neck 174 passing through a slot in the table 36 and connected with the foot 78 which as shown in Figs. 3 and 5 engages with a corresponding dovetail slot in the slide. The

blocks 75 may be firmly secured in this slot at either end of the foot as bv the screws indicated so as to rigidly support the head and connected reciprocating double plunger die for proper coperation with the die boxes and rear dies.

Suitable die boxes 102 and 202 which may have any desired contour, such for instance as the substantially rectangular cross-section indicated may be rigidly mounted in any `desired way as by securing them to the rear dies at other times by suitable connections, preferably including cams on the plunger slide itself. For example, the rear die 71 may be secured in any desired way to the sleeve 21 provided with a suitable collar, such as 20, and longitudinally guided from the frame. The spring buferA may comprise the buifer block 30 adjustably mounted in the frame member 41 and the buffer head 31 mounted in the guide 104 provided with a suitable guide-slot 32 with which the screw 28 in the cover 27 may cooperate to limit the forward movement of this buffer head under the influence of the heavy spring 29. By adjusting the position of the buffer block the degree of spring resistance which the rear die meets with in its active compressing condition when the collar 20 engages the buffer head may be adjusted as desired.

It is desirable with panel cakes of soap or the like to have amovably mounted panel member mounted in the rear die and this may be conveniently effected by having the panel 222 mounted in a suitable recess in the die 71 and secured to the stem 23 by the rod 24, for example, which may screw into the rear end of this panel member and be drawn rearward therewith by suitable nuts, such as 26. The connections for operating the rear dies may comprise suitable die levers, such as 13 pivoted about the pin 33 and having an inwardly projecting yoke or pin members 18 engaging the lcollar 20 as shown in Figs. 2 and 4. The free end of this lever may be provided with the roll 16 coperating with a suitable cam 11 preferably connected with or formed integral with the plunger slide 10 and this cam may be provided with a relieved portieri 211 at its upper end so that during active com-- pression the rear die and buffer may yield to the desired extent so as to insure a detinite degree of compression as the plunger die 63 is forced forward by the slide as shown in Fig. 2. The soap cake 72 is thus formed inthe desired way and then as the pressure is relieved the spring buffer carries the rear die and its connected lever down into the position shown in Fig. 2 and then the further movement of the plunger slide and its cam`11 brings the rear die 71 forward practically in time with the plunger die 69 until the bottom portion 212 of the cam is reached. At this time a suitable spring gripper, such as 59, is brought firmly into engagement with the soap cake and then the slight rise in the cam 11 retracts the rear die slightly and moves it clear of the soap cake which may be engaged by delivery mechanism to be discharged. This is shown in the case of the soap cake 7 2 engaged by the spring-pressed gripper 157, the rear die 171 having been retracted out of engagement therewith so that this completed cake when again released by the gripper 157 may be engaged by the delivery finger 56 and carried awajv7 over the table 3G. This rear die 171 is as indicated similarly connected with the sleeve 121 provided with the collar 19 to cooperate with the buffer head 131 sliding in the guide 105 of the similarly constructed buffer device. The die lever 14 pivoted about the pin 35 is provided with the yoke 17 similarly engaging this collar and its free end may be provided with the similar roll 15 engaging the cam 12 shown in dotted lines in the plunger slide 10. The panel member 221 of this rear die may be similarly connected with its stem 123 by the rod 124 and nuts 126. The panel die member may during this operation be moved sufiiciently to assist in disengaging the soap cake from the rear die and this may be accomplished by suitable trip devices such as are shown in Fig. 1. A suitable bracket 107 may be secured by its collar 120 upon the sleeve 121 and a trip 111 may be pivoted about the pin 108 in this bracket so as tocooperate with the two collars 117, 11S secured on the stem 123. The spring 122 normally tends to force the stem and its connected die panel rearward so as to rotate the trip 111 into engagement with its adjustable stop 207 on the bracket, but when this rear die has moved forward to its eXtreme position the roll 106 on the trip is brought into engagement with the releasing cam 110 on the frame so as to rock this trip about its pin and project the die panel forward beyond its normal position, thus disengaging the soap cake from the die. At this time the spring gripper comes down into engagement with this soap calze 72 and holds it in delivery position while the rear die moves back slightly out of contact therewith. This trip device is identical in construction with that provided in connection with the other rear die, whose trip 112 is mounted about the pin 113 and operates between the collars 116 on the stem so as to project the die panel slightly when 4the roll 114 on the trip engages the stationary cam 115. The spring grippers 57, 157 referred to may be provided with a yielding face of rubber or other suitable material and may be mounted on the gripper arms 58, 15S which may be disengageably connected with their pivots or stub shafts 144, 145, so that these gripper arms may be released therefrom and bodily swung up away from the dies for inspection or adjustment thereof. Any desired means may be used for this purpose, as for example by releasing the nuts 244, 245 and then swinging the arms upward. As shown in Fig. 3 these gripper arms are provided with depending portions connected with suitable springs, such as 80 connected to the stud 81 in the frame member 4 so as to normally bring the cam roll 7 9 on this gripper into engagement with its cam 133 on the gripper shaft 137. As shown in Fig. 4, a similar cam roll 135 is brought into coperation with the cam. 136 on this same shaft. In this way, the gripper springs bring the grippers down into momentary engagement with the completed soap cakes at the time the rear dies are being withdrawn therefrom and then the grippers are again raised while the discharger fingers engage and carry away the cakes. As is indicated in Fig. 1, this gripper cam shaft 137 is provided with the gear 93 meshing with the gear 94 on the stub shaft 98 which also carries the beveled gear The corresponding beveled gear 9G on the main shaft 2 drives this cam shaft through these connections.

The feed devices may comprise a removable feed frame 51 which may be pivoted about the feed shaft 52. The free end of the frame may be held in any desired position as by providing the latch G0 having the pivoted operating handle so that the latch may coperate with any one of the catches 64 in the sector 63 mounted on the main frame. The spring locking handle 59 also mounted in this swinging feed frame coperates with a suitable hole in the sector support so that on pulling out this locking pin shown in Fig. 1, the frame may be swung upward to the desired extent in which it will be held by the latch 60 shown in dotted lines, Fig. 3. The latch may be swung out of engagement with its catch 64 by operating its handle and then the frame may be again lowered. It is desirable to provide a suitable spring 54 to counterbalance the weight of this feed frame and this spring may be connected between the pin 55 and the extension 53 of the swinging frame. The soap blanks 72 may be fed into the machine on the supply belt 37 passing over the roll 38 adjustably mounted in the bracket 39 so as to be taken up by the adjusting screw 40 shown in Fig. 2. This supply belt as indicated in Figs. 1 and 4, passes over the roll 101 at its forward end and feeds a continuous row of the soap blanks against a suitable stop 285 so as to be carried through the felt faced cleaners 66 by the feed fingers 49 on the feed chain 45 shown in Fig. 3. This chain runs on the sprocket 48 having its pin 49 mounted in suitable bearings in the bracket 50 and thechain also runs over the driving sprocket 43 on the shaft 67. The feed finger 47 engages the fixed retractor 62 mounted on the swinging frame and the feed linger is thereby swung up out of engagement with the soap blank which is thereby left in proper position on the table 36.V The soap blanks are thus always left by the feed fingers 47 in the central position shown in Fig. 2 and distributed by the reciprocating double plunger die which as it travels to the left feeds the first blank into the left hand die box 102, then as it travels back to the right feeds the succeeding blank into the right hand die box 202 to be pressed in connection with the rear die therein. This feed frame 51 also carries the

duplex delivery chains

46 and 146 mounted on suitable sprockets and provided with the delivery fingers 56 arranged at suitable intervals on the chains. These delivery fingers engage the finished soap cakes as 73 in Fig. 3 and carry them forward over the table 36 upon the

discharge belts

156 and 256 on the rolls 85 on the shaft 86. This shaft is provided with the spur gear 87 meshing with the gear 88 on the gripper cam shaft 137 operated as described. As shown in Fig. 1, the sprocket wheel 90 of this same cam shaft operates the sprocket chain 138 passing over the corresponding sprocket 91 on t-he feed shaft 52 so as to operate the feed and delivery chains. Any suitable gearing may be used to operate the supply belt as for instance the sprocket chain 285 passing as shown in Fig. 3 over the

sprockets

185 and 84 on the shaft 34 which may carry the beveled gear 85 meshing with the beveled gear onv the shaft 83. This shaft also carries the beveled gear 82 which as shown in Fig. 4 meshes with the beveled gear 182 on the gripper cam shaft 137 operated as described. Y Having thus described this invention in connection with illustrative embodiments,
