A Y

The machine is also provided with ,a dish stacking mechanism operable from the machine and comprising a plunger 138 the upper ehd of which is curved downwardly and has a'conical pusher head 139 mounted-on the end thereof and adapted to be movedinto a position to engage in a discharged receptacle or dish to move the same into the stacking mechanism as hereinafter described. The Also mounted on the clutch sleeve 117 Ais.

plunger rod 138: is slidably mounted and projects through a guide sleeve 140 integrally formed on the upper end of a standard or bracket 141 the lower end of which is securely supported on the horizontal flange ofthe angle bar 135. Secured to the lower projecting end of the plunger rod 138 below the guide sleeve 140 is a Coupler 142 to which the upper end of'a plunger link or bar 143 is pivotally connected. The lower end of the link 143 is pivotally connected to the end of the long arm .of a bell crank 144. The bell crank.144 is pivotally supported on a shaft 145 (Figure 3) supported in suitable bearings mounted on the machine frame. Pivotally connected to the end of the short arm of the bell crank 144 is the upper end of a connecting rod 146. The lower end of the connecting rod 146 is pivotally connected to the free end of a crank arm 147 the other end of which is secured to one projecting end of the shaft 108. Also secured on the shaft 108 between the bearing 110 and the hub of the bell crank 106107 is a crank arm 148 on the free end of which a roller 149 is mounted.

' The roller 149 is positioned to track on the periphery of the cam 119 to be actuated thereby. For the purpose of holding the roller 149 in resilient contact with the flange 119 a I coiled spring 178 isprovided with the lower end of said spring 178 connected to the short arm of the bell crank 144 while the upper end of said coiled spring is connected to a cross member of the machine frame. .For the purpose of holdingthe roller 112 in contact with the periphery of the cam 113 a coiled controlled spring 150 isprovided with the lower end of said control spring connected to the long bell crank arm 106 (Figure 3). The upper end of the coiled spring 150 is attached to a cross member of the machine frame.

The pusher head 139 is adapted to be actuated by the control cam 119 so that, when a dish 151 (Figure 3) is removed from the forming mechanism and transferred over the,

table 32 by the transfer bracket-99, said pusher head will move into engagement with the dish 151 to push the dish downwardly through an opening 152 provided in a plate 153 which is mountedcto set in the cut out portion in the table 32. Secured to the bottom of the plate 153 by means of screws or other suitable .means is a pair of oppositely positioned segment shaped retaining rails or guide segments 154. The inner curved edges of the guide segments 154 project into a peripheral groove 155 provided in the outer periphery of a dish receiving sleeve or collar 156. The dish receiving sleeve 156 is positioned below the plate 153. Secured on the inner face of the sldeve 156 between suitable guide ribs is a plurality of plates the upper ends of which are tapered and bent inwardly and downwardly to afford inclined spring tongues or fingers 15.7 which act to prevent dishes from, moving upwardly out of said having a longitudinal slot or opening 160 therein. 'The tube 159 is adapted to receive the dishes in nested relation one within the other due to the operation of the pusher head 139. Forined on the inner face of the bottom 161 of the can 159 is a plurality of vanes or ,plates 162 which serve to afford a pocket for receiving a tapered or conical dish receiving holder 163. The bottom of the holder 163 is provided with a boss or base 164 having a recess or notch 165 in the bottom thereof (Figure 10). The can 159 has the bottom thereof removably seated in a can holding disk or plate 166 provided with a passaged boss 167 which is supported upon the horizontal flange of the angle bracket 135. Projecting through an opening in the angle bracket 135 and through the boss 167 is the upper end of a slidable stem or rod 168. The upper end of the stem 168 also slidably projects through the apertured bottom 161 of the dish receiving can and seats in the recess 165 of the dish holder 163. .The stem 168 is long enough to permit the holder 163 to be raised to the top of the can 159. Secured on the lower end of the stem 1 68 is a head 169 to which a radially directed arm 170 is secured. "Connected to the outer end of the arm 170 is one end of arope or cable 17.1 to the other end of which a counterweight 172 is secured. The cable 171 passesover guide pulleys 173 which are supported on the angle bar 135.

For the purpose of rotating the can or tube 159 at predetermined times to cause the de-- posited dishes to be nested within the tube" with the folded portions thereof staggered, a pinion 174 is positioned to mesh with the ring gear 158 (Figure 9). The pinion 174 is secured on the upper end of a vertical shaft 175 which is positioned adjacent the can or tube 159 with the lower end of said shaft projecting through a bearing plate 176 mounted upon the bearing plate 111. Securedon the lower projecting end of the vertical shaft 175 is a bevel pinion 177 which is inmesh with the bevel pinion 118. v

The operation is as follows:

To operate the receptacle forming machine,

a driving belt connected with any suitable source of power is trained over the driving pulley 3 to cause rotation of the main drive shaft 2. A drive from the shaft 2 is transmitted through the chain 17 to the auxiliary shaft 18 and to the bevel pinion 20. The bevel pinion 20 is thus adapted to impart a drive to the blank feeding mechanism of the machine. The bevel pinion 20 being in mesh with the bevel gear 21 acts to rotate the same and the gear 46. The hollow shaft 22 is thus rotated.

When the machine is started a stack of circular sundae dish blanks is deposited inthe magazine33 with the lowermost blank resting upon the pin.35 and upon the disks 29 of v or handle thereby causing the the feed reel.

When it is desired to cause dish be. fed out of the magazine 33 onto the table 32 an operator pushes inwardly on the knob shaft 24 to slide inwardly with the plus 26 moving in the slots 27 of; the hollow shaft 22 into a position tokcoact with the pin 28 secured in one end of the feed reel. The pins 26 thus act to transmit a drive from the hollow shaft 22 to the blank feed reel through the pin 28. The reel 293O is thus rotated and when the friction pad 31 on said reel moves into its uppermost position it frictionally engages the lowermost blank in the ma azlne 33 and feeds said blank from the magazine between the rollers36 and 37. The roller 36 receives a drive from the gears 46 vand while the lower roller 37 is rotated from the upper roller through the small gears 41 and 42. The rotating feed rollers 36 and 37 act to feed the bank from the magazine onto the table 32. As the above operation takes place the pusher arms 5,3 are in their retracted position engaged in, the grooves of the lower feed roller 37. After the. dish blank has been sufliciently advanced by the rollers 36 and 37 the pusher arms 53 are actuated-by means of the cam '47 (Figure 7) blanks to which coacts with the roller48 on the arm 49 -to cause said arm to slide away from the hol- "blank forwardl stops 55. As th low shaft 22. The crank arm 50 is thus actuated to rotate the shaft 51 to cause the pusher and compression of the spring 73 and at U1e so that the forming member is permitted to be gradually lowered so that the gripping plates 191 are closed by the action of control springs to permit said gripping plates to grip the centered dish blank. At the time a dish blank is advanced onto the table 32 against the stops 55 the cam 61 on the shaft 2 is adapted to actuate the fulcrumed' bar 57' thereby causing the rod or pin 56 to be projected upwardly through the opening in the table to elevate a "portion of the a vanced I disk blank so that said blank engaged between the gripping plates of the dish forming mechanism may be moved away from the stop pins 55 and bepositioned at an angle to more easily pass over an edgeof the table whenthe gripping plates are rotated to form the blank into a sundae'dish.

' The action of the disk 7 and its roller 8 upon the Geneva gear 9 now commences and the gripping ,7 plates 191 are thus rotated through a half revolution to fold the blank into the form of a conical sundae dish. After the forming of the dish as described a raised portion on the cam 88 comes into engagement with the roller 87 to raise the. formingmember 65 to cause separation of the gripping plates. The advanced blank having been formed into a receptacle or dish by the forming mechanism it is now ready to be discharged from the forming mechanisms and delivered to the stacking attachment of the machine. v

At the beginning of the operation of the arms 53 to swing upwardly through the table machine an operator merely swings the con slots 54 to engage and ush the advanced disli on t e table 32 against the e pusher arms 53 push the blankagainst the stops 55 the upper ends of the positioning arms 74 are actuated in the table slot 75 and move inwardly toward the front of the machine to further position and center the dish blank on the table in the field of operation. of the dish forming mechanism.

The positioning arms 74 are carried by the arm 76 which is secured on the shaft 77. The shaft 77 is rocked or partially rotated by means of the bell crank 79 the roller 83 of which coacts with the cam 84 mounted-on the cam shaft 2.

The gripper plates 191 of the dish forming mechanisms are separated during the time the blank is being positioned; this separation is accom lished by swinging the member '65 about its pivoted point 69 by means of the cam 88 which acts on the roller 87 to raise the bar 89. Elevation of the bar 89 causes one end of the fulcrumed arm 90 to move upwardly thereby contacting the shoe 91. The shoe 91 being mounted on one of the arms 66 thus causes elevation of the forming member 65 trol arm 131 into the position illustrated in Figure 1 thereby causing the arm 129 to tension the spring 130 while is moved into a position to. engage inthe notch-in the horizontal flange of the angle bar 135. Swinging ofthc arm 129 causes a partial rotation of the vertical iaft 127 thereby causing the yoke 124 to' nove the clutch collar 122 into the position illustrated in Figure 4 wherein the pin 120 is adapted to engage in the notch 121 of the shiftable clutch collar 122. WVhen the clutch is thrown in as described a drive is imparted to the cam 113 and thereby to the crank 106-107 which in turn operates the connecting rod 105 and the bell crank 101104 to cause the receptacle pusher bracket 99 to move outwardly across the table 32 to transfer the formed receptacle gripped the latch rod 134 ring gear 158.

actuates the bell crank 144 on the shaft 145 to cause reciprocation of the link bar 143 and the pusher rod 138 of the receptacle stacking mechanism. With the lowering of the pusher rod 138 the plunger head 139 is lowered to seat in the formed dish and push said dish from the transfer bracket-99 through the opening 152 in the table plate 153. The dish is thus pushed into the rotatable sleeve 156 past the resilient fingers 157 and into the upper end of the receptacle receiving tube or can 159. As the dish is pushed through the sleeve. 156 the edge of the dish is slightly indented while passing the resilient fingers 157 When said fingers have passed the fingers 157, the dish automatically opens up again so that the rim of the dish will engage beneath the retaining fingers 157 to prevent the dish from moving or spring upwardly out through the table plate aperture 152. When a dish is pushed into the tube 159 the dish holder 163 is held in its uppermost'position in the can by the counterweight 17 2 which acts to hold the stem or shaft 168 in a raised position thereby also causing elevation of the dish holder 163 within the tube 159. The dishes when formed are thus stacked in nested relation one within the other in the receiving tube 159 supported by the dish holder 163;

When the clutch sleeve 122 is in driving position the bevel gear 118 is also rotated thereby causin rotation of the bevel gear 177 on the verticzfi shaft 175. The pinion 174 on the upper end of the shaft 175 is thus also rotated and acts to transmit a drive to the Rotation of the ring gear 158 causes rotation of the sleeve 156 and the tube 159 each time a formed dish is delivered into said tube. By rotating the receptacle or dish receiving tube 159 when dishe sn delivered thereto the dishes are stacked ested one Within the other so that the folded portions of the dishes are deposited in staggered relation to permit the dishes to form] a straight stack which will not tend to bend or curve as is the case when dishes are stacked with the folded portionsof said dishes deposited one above the other. The dishes are thus transferred from the forming mechanisms and delivered into the receiving tube 159 and are prevented from springing upwardly out of the table opening 152 by the retaining fingers 157. Each time a dish is deposited in the tube 159 the dish holder 163 is lowered a predetermined amount so that the stack of dishes may be increased in height with the counter weight 172 acting to hold the dish holder 163 resiliently against the lowermost dish thereby serving to apply a continuous pressure against all of the dishes in the stack. When the dish holder 163' reaches the bottom of the tube 159 the'operator in charge of the machine manually pulls the knob 25 outwardly thereby causing the driving pin 26 on the shaft 24 to be moved out of engagement with the reel pin 28. The

blank feed mechanism may thus be stopped at any desired time either when the tube is completely filled or'only partially filled.

The dish transfer mechanisms controlled by the operation of the cam 11.3 and the dish stackin mechanisms controlled by the operation of the cam 119 may be stopped at any desired time by the operator who merely presses downwardly on the control lever 133 (Figure 3) thereby lifting the latch rod 134 against the action of the spring 136. \Vhen the latch rod 134. is lifted the lower end of the rod is lifted out of engagement with the horizontal flange of the angle bar 135. The clutch control arm 129 is thus unlatchcd or released permitting the control spring 130 to swing the arm 129 away from the tube 159 thereby causing theclutch control shaft 127 to rotate to cause the yoke 124 to move the clutch sleeve 122 into a released position out of engagement with the pin 120. The drives to the cams 113 and 119 and the bevel gear 118 are thus discontinued thereby stopping the dish transfer mechanism and the dish stacking mechanism.

The shaft 13 is driven from the gears 11 and 12 the operation of which are governed by the Geneva gear 9 which is adapted to receive a drive from the roller 8 carried by thev disk'7mounted on the main driving shaft 2. The bevel pinion 14 being mounted on the shaft 13 acts to operate the bevel pinion 15 thereby causing operation of the dish forming mechanisms. If, however, at any time, it is desired to stopthe operation of the dish forming mechanisms the hand wheel 64 may be operated to cause theclutch 63 tobe'moved into a position wherein the drive from the ar shaft 13 is not transmitted to the dish form-' ing mechanisms. It will thus be noted that a dish or receptaless cle forming unit is adapted to receive a drive from a common source and furthermore is adapted to have the blank feeding mechanisms, and the dish formingmech nisms to be controlled independently of the dish transfer mechanisms and the dish stacking mechanisms to permit starting or stopping of said various mechanisms of a unit at the will of an operator, without interfering with the operation of similar mechanisms of other dish or receptacle forming units which may be connected with the same driving source.

A receptacle forming machine has thus been provided wherein any desired number of units may be connected to receive a drive from a common source with each of said units having the various mechanisms thereof adapted to be independently controlled without interfering with the operation of any of the other machine units.
