- i represents a printing or stamping machine of a generally conventional type and having a stationary die 2 and a printing bed or platen 3, vertically movable toward and from the die in a printing action.
- the platen which supports the article which is to be printed or embossed, moves upwardly to raise i the article and foil to printing position whereby the foil is pressed against the printing face of the die which impresses the foil, the impressed portion of the foil being separated from the foil strip and adhesively applied to the article, after which the platen moves downwardly to retracted position to release the article: for removal and the foil for a feed action to bring a new portion of the foil into stamping position and in readiness for arepetition of the above described stamping operation.
- the stamping machine may be of any conventional type and operated in any suitable manner. It is not shown in detail and is only conventionally shown for the purpose of illustrating the application of my improved feeder thereto, as, except for its mode of operation in connection with and upon the foil supplied to it by the feeder, its particular construction is immaterial and merely representative of one of various makes of stamping machines to which the feeder may be applied.
- the feeder generally indicated at i, is illustrated in the form of an attachment to the printing machine, although it is to be understood that it may, if desired, be built into a stamping machine as a component part of the machine.
- the feeder 4 comprises a casing of generally oblong form in plan and including side walls 5 and 6, an inner end wall I, and a top wall 8, said side walls and the top wall 5 having sloping outer end portions 9 and ID, the latter closing the upper portion of the outer end of the casing.
- a portion of the wall 8 is cut away or recessed as shown at H to receive a bed plate 12 supporting an electric motor 13 and an instru ment board it having plug in connections i 5, I6 and IT, to theterminals of which are connected conductors of an electric controlling circuit generally indicated at S8 in Fig. 14.
- the timer may consist of a micro-switch member 19 adapted to be periodically opened and closed by a contact element 2E3 on or actuated by a suitable part of the running gear of the stamping press, whereby on each printing cycle of the press the circuit 18 will be periodically opened and closed.
- the feeder is suitably attached at its end 1 to one end 2! of the frame or casing of the press above the level of the bed plate 3 so as to be disposed in proper position to feed the foil strip or strips longitudinally of the frame and between the bed plate and die for the action of the die thereon.
- a support 23 Arranged at the opposite end 22 of the press is a support 23 in which are journaled a plurality of supply spools or rolls a, b and c on which alike number of foil strips, sheets or tapes (1, b, c are wound and from which the strips are extended downwardly over guide rolls d, thence horizontally over the platen 3 to guide rolls (1', and thence upwardly to set-s of gripping and feed rolls mounted in the feeder and in the operation of which the foil strips are drawn or pulled forwardly the same or different distance on each feed motion, as required, to bring them in stamping position.
- the feeder is shown as equipped with sets of supply and feed rolls for feeding a single strip or two or three foil strips at a time, although in practice the structural organization may be designed to feed more or less than three strips according to the use to which the machine is to be put.
- the sets of gripping and feed rolls are arranged in properly spaced rotation in the casing of the feeder, and each set comprises a knurled or serrated drive roll 24 and coacting pressure and drive roll 25.
- the roll 2 is preferably made of metal and is rotatable on a fixed axis, said roll having a spindle 26 at one end journaled in the wall 5 and a spindle 21 at its opposite end journaled in the wall 6 and extending outwardly therethrough.
- the roll 25 is preferably a rubber surfaced roll arranged to yieldingly press the foil against the surface of the roll 24, whereby the foil is gripped for a feed action sufficiently tight to prevent slippage.
- Roll 25 is journaled at its ends in a bracket embodying spaced arms 29 pivoted at 29' to the walls 5 and 6 for swinging adjustment of the roll 25 toward and from the roll 24, said arms being connected by an upper arcuately curved or hood shaped deflector plate 3
- the lower ends 30 of these arms project below their pivots to form counterweights and handles for convenience in moving the roll 25 away from the roll 24 to release foil in case the foil is started in the wrong place.
- Springs 3 i arranged between the forward portions of the bracket arms and seat blocks 32' cooperate with the counterweights to overcome this tendency and to cause the roll to press the foil with just sufficient pressure against the roll 24'. to cause the foil to be gripped without injury but for a positive feed motion during a feed action of the rolls and a positive holding action when the rolls are at rest.
- the rolls operate to pull or draw the foil forwardly when they are in motion, the foil passing between them and beneath the deflector 3
- the function of the curved deflector 3! is to guide the foil as it issues from the roll toward the guide plate 32, by which further contact of the foil with the rolls beyond the gripping point is prevented.

- the free end of the dog has a seat face 68 normally engaged by the beveled outer end 69 of a sliding latch 16.
- the dog 64 is adapted, when free to swing outward, to engage a tooth 63 of gear 56 to couple said gear to the shaft and effect the driving of the shaft for a working operation of the strip feeding devices, but when the dog is engaged by the latch I6 it will be held retracted and out of the path of the teeth 63 so that, although the shaft 48 and gears 55 and 56 may be continuously driven, shaft 51' will remain idle until the dog 64 is released by the latch 16 and engages one of the teeth 63 to couple the gear 56 and shaft 51 together.
- a double cam embodying a cam member ll having a 90 cam rib or portion 12 and a cam member '16 having a cam locking recess M adapted to be engaged by a stop roller 15 on one end of a sliding detent or looking plunger 76 mounted in a guide casing 11 on the bottom of the motor bed and normally urged to engaging position by a spring 18.
- Latch 10 is mounted in a guide casing 19 and normally urged outward to locking position by a spring 19 and said latch is connected to the armature core 86 of an electric solenoid 8
- the solenoid and a micro-switch 82 are arranged in the controlling circuit IS.
- the solenoid and detent as well as the latch are preferably mounted on the underside of the motor bed to form therewith and with the motor, and the instrument board and its attachments, if desired, a readily attachable and detachable unit.
- the lever member 83 of the micro-switch 82 is arranged so as to be periodically engaged and released by the cam rib 12 of cam member 1 I.
- the circuit I8 includes the solenoid coil, themicroswitch and three plug-in sockets l5, l6 and I7 adapted to be engaged, respectively, as hereinbefore stated, by a connector plug I5 on a cord or conductor leading from a power circuit or source of current supply, a connector plug I6 on a cord or conductor leading from the motor, and a connector plug ll leading from a timer, as previously stated, mounted on the stamping machine.
- This timer may consist of a microswitch member i9 arranged so as to be periodical- 1y closed and opened by an operating or controlling cam or element 20 arranged on or actuated by some suitable part of the running gear of the stamping machine, so that the feeder will be operated in synchronism or timed accord with the'stamping die of the stamping machine.
- the rib 12 on the cam H engages and moves the micro-switch lever 83 and actuates the micro-switch 82 which breaks solenoid circuit, causing the solenoid to release the latch I6 on a turn so that thereafter the free end of the latch will travel in contact with the surface of the shaft 51 until the shaft has made one complete rotation when the latch will again engage and retracts the dog to stop the motion of the shaft 51 and operation of the feeder.
- the use of the micro-switch allows a quick stopping action to be obtained at the instant the foil strips are brought up to the exact impression position for each strip.
- the setting of the shaft 57 in motion causes movement of cam member [3 to withdraw its locking recess M from engagement with the roller 15 of the detent I6 and to hold the detent retracted until the recess 14 again comes into register with the roller, whereupon the detent will be projected into locking engagement with the recess to lock the shaft 51 and the strip feeders against casual motion and in retracted position, at the instant the rotation of the shaft 51 ceases at the end of a strip feeding operation in readiness for the next succeeding strip feeding operation of the stamping machine and feeder.
- the setting of the shaft 51 into motion effects actuation of the rack and pinion strip feeding devices, which on their forward strokes rotate the sets of rolls 24 and 25 for a feed action and then return on an idle stroke or traverse back to normal position, such idle traverse being permitted by their one-way clutch connections with the rollers.
- the construction and arrangement is such that the drive shaft, transmission shaft, crank disks, and gearing for operating the disks are disposed and supported at the upper portion of the feeder casing in spaced relation longitudinally of the casing, while the sets of feed rolls are disposed and supported at the lower portion of the casing below the first named parts and likewise in spaced relation longitudinally of the feeder casing, and that the drive pulley 49 is mounted with the drive shaft at one side of the casing, while the crank disks, their drive gears and the rack and pinion connections between the disks and feed rolls are disposed wholly at the opposite side of the casing.
- This arrangement adapts the feeder to be mounted on a conventional stamping machine having a stationary die and a platen movable upwardly toward and downwardly from the die so that all parts of the feeder are arranged at a low level for ready accessibility in inspecting, cleaning, repairing and adjusting them to keep the feeder in proper working order and to permit of the feed of the foil strips horizontally so that no portions of the strips either before or after impressions are made can come in contact with and catch in or otherwise interfere with the gearing or control elements of the feeder.
- the described construction and arrangement of the transmission gears and crank disks at the same side of the feeder casing also permits of the convenient ad J'ustment of the crank pins of the crank disks in during a predetermined portion of the working movement of the transmission shaft and then interrupting the circuit to effect its deenergization and render the clutch device inactive.
- foil feed rolls foil feed rolls, a motor driven drive shaft, transmission means including a transmission shaft rotated once on each cycle of operation of the machine for periodically operating the feed rolls, an automatically acting clutch for connecting and disconnecting said shafts.
- an electric circuit including a latch to normally hold the clutch retracted, a solenoid to release the latch, a timer operated by and in synchronism with the stamping machine to periodically open and close the circuit, and an interrupter in the circuit normally maintaining the circuit in condition to be energized by the timer and controlled by the transmission means to govern the action of the solenoid while the timer is in action to keep the circuit energized for a period while the transmission shaft is rotating and then interrupt it to deenergize the solenoid.
- a foil feeder for printing or stamping machines, feed rolls, a motor driven drive shaft, periodically operated means for operating the rolls including a transmission element, a normally inactive clutch device automatically movable to clutching position when free for action to connect said element with the drive shaft.
- a solenoid operated holding device for normally holding the clutch device from action and releasing it for action
- an electric circuit including the solenoid, means automatically operated by the stamping machine and controlling the circuit to energize the solenoid to retractthe holding device so as to release the clutch device for action to start the transmission element in motion, and means in the circuit normally maintaining said circuit in condition to be energized by the timer and controlled by movement of the transmission element to maintain such condition of the circuit to keep the solenoid energized during a predetermined portion of the working movement of the transmission element and then causing its deenergization to render the clutch device inactive.
- a foil feeder for printing or stamping machines, foil feed rolls, a motor driven drive shaft, transmission means including a transmission shaft for periodically operating the feed rolls, an automatically acting clutch for connecting and disconnecting said shafts, a latch to normally hold the clutch retracted, a normally open electric circuit having two branches, a solenoid in said circuit operable when energized to release the latch and a switch device normally connecting the circuit branches to adapt the circuit when closed to energize the solenoid, a timer governed in action by the stamping machine for periodically closing and opening said circuit, and means controlled by the transmission means and controlling the action of the switch device to first open it at a certain time period in the orbit of rotation of the transmission shaft and then release it to permit it to close at a later time period in the orbit of rotation of the transmission shaft.

Referring now more particularly to the drawings, i represents a printing or stamping machine of a generally conventional type and having a stationary die 2 and a printing bed or platen 3, vertically movable toward and from the die in a printing action. In such action the platen, which supports the article which is to be printed or embossed, moves upwardly to raise i the article and foil to printing position whereby the foil is pressed against the printing face of the die which impresses the foil, the impressed portion of the foil being separated from the foil strip and adhesively applied to the article, after which the platen moves downwardly to retracted position to release the article: for removal and the foil for a feed action to bring a new portion of the foil into stamping position and in readiness for arepetition of the above described stamping operation. The stamping machine, as stated, may be of any conventional type and operated in any suitable manner. It is not shown in detail and is only conventionally shown for the purpose of illustrating the application of my improved feeder thereto, as, except for its mode of operation in connection with and upon the foil supplied to it by the feeder, its particular construction is immaterial and merely representative of one of various makes of stamping machines to which the feeder may be applied.
The feeder, generally indicated at i, is illustrated in the form of an attachment to the printing machine, although it is to be understood that it may, if desired, be built into a stamping machine as a component part of the machine.
As shown, the feeder 4 comprises a casing of generally oblong form in plan and including side walls 5 and 6, an inner end wall I, and a top wall 8, said side walls and the top wall 5 having sloping outer end portions 9 and ID, the latter closing the upper portion of the outer end of the casing. A portion of the wall 8 is cut away or recessed as shown at H to receive a bed plate 12 supporting an electric motor 13 and an instru ment board it having plug in connections i 5, I6 and IT, to theterminals of which are connected conductors of an electric controlling circuit generally indicated at S8 in Fig. 14. The connections [5, l6 and I! are respectively adapted for the engagement therewith of coacting connectors of conductor cords or leads i5, 16' and H extending from a source of power (current supply), from the motor I3 and from a timer. The timer may consist of a micro-switch member 19 adapted to be periodically opened and closed by a contact element 2E3 on or actuated by a suitable part of the running gear of the stamping press, whereby on each printing cycle of the press the circuit 18 will be periodically opened and closed.
in l
The feeder is suitably attached at its end 1 to one end 2! of the frame or casing of the press above the level of the bed plate 3 so as to be disposed in proper position to feed the foil strip or strips longitudinally of the frame and between the bed plate and die for the action of the die thereon.
Arranged at the opposite end 22 of the press is a support 23 in which are journaled a plurality of supply spools or rolls a, b and c on which alike number of foil strips, sheets or tapes (1, b, c are wound and from which the strips are extended downwardly over guide rolls d, thence horizontally over the platen 3 to guide rolls (1', and thence upwardly to set-s of gripping and feed rolls mounted in the feeder and in the operation of which the foil strips are drawn or pulled forwardly the same or different distance on each feed motion, as required, to bring them in stamping position. In the present instance, the feeder is shown as equipped with sets of supply and feed rolls for feeding a single strip or two or three foil strips at a time, although in practice the structural organization may be designed to feed more or less than three strips according to the use to which the machine is to be put.
The sets of gripping and feed rolls are arranged in properly spaced rotation in the casing of the feeder, and each set comprises a knurled or serrated drive roll 24 and coacting pressure and drive roll 25. The roll 2 is preferably made of metal and is rotatable on a fixed axis, said roll having a spindle 26 at one end journaled in the wall 5 and a spindle 21 at its opposite end journaled in the wall 6 and extending outwardly therethrough. The roll 25 is preferably a rubber surfaced roll arranged to yieldingly press the foil against the surface of the roll 24, whereby the foil is gripped for a feed action sufficiently tight to prevent slippage. The rolls are coupled at their ends adjacent the wall 6 by gears 28 and 28' to rotate in unison at the same peripheral speed. Roll 25 is journaled at its ends in a bracket embodying spaced arms 29 pivoted at 29' to the walls 5 and 6 for swinging adjustment of the roll 25 toward and from the roll 24, said arms being connected by an upper arcuately curved or hood shaped deflector plate 3| and an outer outwardly and downwardly inclined deflector or guide plate 32. The lower ends 30 of these arms project below their pivots to form counterweights and handles for convenience in moving the roll 25 away from the roll 24 to release foil in case the foil is started in the wrong place. Springs 3 i arranged between the forward portions of the bracket arms and seat blocks 32' cooperate with the counterweights to overcome this tendency and to cause the roll to press the foil with just sufficient pressure against the roll 24'. to cause the foil to be gripped without injury but for a positive feed motion during a feed action of the rolls and a positive holding action when the rolls are at rest. The rolls operate to pull or draw the foil forwardly when they are in motion, the foil passing between them and beneath the deflector 3| and downwardly and outwardly over the guide plate 32. The function of the curved deflector 3! is to guide the foil as it issues from the roll toward the guide plate 32, by which further contact of the foil with the rolls beyond the gripping point is prevented. The tendency of the foil as it passes beyond the gripping portions of the rolls is to follow along and cling by cohesion and static attraction to the surface of. the roll 24, which, if allowed, would cause an accumulation of foil in itheregicntofrthe ripping 1-point a d :elosein aof ethehrollsi iwithi gliability rofxstcnpage at thevieeder rand breakage-hf :the delicate foil endless ef time zgrequitedto remedyithe diflicu1ty;::aswelliasqviaste ioffoil.

The free end of the dog has a seat face 68 normally engaged by the beveled outer end 69 of a sliding latch 16. The dog 64 is adapted, when free to swing outward, to engage a tooth 63 of gear 56 to couple said gear to the shaft and effect the driving of the shaft for a working operation of the strip feeding devices, but when the dog is engaged by the latch I6 it will be held retracted and out of the path of the teeth 63 so that, although the shaft 48 and gears 55 and 56 may be continuously driven, shaft 51' will remain idle until the dog 64 is released by the latch 16 and engages one of the teeth 63 to couple the gear 56 and shaft 51 together. On the shaft 5'! is also mounted a double cam embodying a cam member ll having a 90 cam rib or portion 12 and a cam member '16 having a cam locking recess M adapted to be engaged by a stop roller 15 on one end of a sliding detent or looking plunger 76 mounted in a guide casing 11 on the bottom of the motor bed and normally urged to engaging position by a spring 18. Latch 10 is mounted in a guide casing 19 and normally urged outward to locking position by a spring 19 and said latch is connected to the armature core 86 of an electric solenoid 8|. The solenoid and a micro-switch 82 are arranged in the controlling circuit IS. The solenoid and detent as well as the latch are preferably mounted on the underside of the motor bed to form therewith and with the motor, and the instrument board and its attachments, if desired, a readily attachable and detachable unit. The lever member 83 of the micro-switch 82 is arranged so as to be periodically engaged and released by the cam rib 12 of cam member 1 I. The circuit I8 includes the solenoid coil, themicroswitch and three plug-in sockets l5, l6 and I7 adapted to be engaged, respectively, as hereinbefore stated, by a connector plug I5 on a cord or conductor leading from a power circuit or source of current supply, a connector plug I6 on a cord or conductor leading from the motor, and a connector plug ll leading from a timer, as previously stated, mounted on the stamping machine. This timer may consist of a microswitch member i9 arranged so as to be periodical- 1y closed and opened by an operating or controlling cam or element 20 arranged on or actuated by some suitable part of the running gear of the stamping machine, so that the feeder will be operated in synchronism or timed accord with the'stamping die of the stamping machine.
Having described in general the working op stations of the several parts of the feeder, the operation of the stamping machine and feeder may be briefly described as follows:
Assuming that the stamping machine is running with the work to be embossed resting on the platen, that the foil feed motor is in operation with the pulley 49 running idly, that that portion of the circuit including the motor is in connection with the source of current, that the foil strips are arranged for unused portions of the strips to be fed up, and that the timer switch l9, which operates once on each working cycle of the stamping machine, is about to be closed by member 20 to connect that portion of the circuit I8 containing the solenoid 8|, and normally closed by the micro-switch 82, with the source of current, it will be understood that on the closing of the switch is the solenoid wil1 be energized to retract the latch 10, whereupon the dog 64 will engage the clutch member 63 to set the shaft 51 in motion. When this shaft begins to turn, the rib 12 on the cam H engages and moves the micro-switch lever 83 and actuates the micro-switch 82 which breaks solenoid circuit, causing the solenoid to release the latch I6 on a turn so that thereafter the free end of the latch will travel in contact with the surface of the shaft 51 until the shaft has made one complete rotation when the latch will again engage and retracts the dog to stop the motion of the shaft 51 and operation of the feeder. The use of the micro-switch allows a quick stopping action to be obtained at the instant the foil strips are brought up to the exact impression position for each strip. The setting of the shaft 57 in motion causes movement of cam member [3 to withdraw its locking recess M from engagement with the roller 15 of the detent I6 and to hold the detent retracted until the recess 14 again comes into register with the roller, whereupon the detent will be projected into locking engagement with the recess to lock the shaft 51 and the strip feeders against casual motion and in retracted position, at the instant the rotation of the shaft 51 ceases at the end of a strip feeding operation in readiness for the next succeeding strip feeding operation of the stamping machine and feeder. The setting of the shaft 51 into motion effects actuation of the rack and pinion strip feeding devices, which on their forward strokes rotate the sets of rolls 24 and 25 for a feed action and then return on an idle stroke or traverse back to normal position, such idle traverse being permitted by their one-way clutch connections with the rollers.
It will be observed that in my machine the construction and arrangement is such that the drive shaft, transmission shaft, crank disks, and gearing for operating the disks are disposed and supported at the upper portion of the feeder casing in spaced relation longitudinally of the casing, while the sets of feed rolls are disposed and supported at the lower portion of the casing below the first named parts and likewise in spaced relation longitudinally of the feeder casing, and that the drive pulley 49 is mounted with the drive shaft at one side of the casing, while the crank disks, their drive gears and the rack and pinion connections between the disks and feed rolls are disposed wholly at the opposite side of the casing. This arrangement adapts the feeder to be mounted on a conventional stamping machine having a stationary die and a platen movable upwardly toward and downwardly from the die so that all parts of the feeder are arranged at a low level for ready accessibility in inspecting, cleaning, repairing and adjusting them to keep the feeder in proper working order and to permit of the feed of the foil strips horizontally so that no portions of the strips either before or after impressions are made can come in contact with and catch in or otherwise interfere with the gearing or control elements of the feeder. The described construction and arrangement of the transmission gears and crank disks at the same side of the feeder casing also permits of the convenient ad J'ustment of the crank pins of the crank disks in during a predetermined portion of the working movement of the transmission shaft and then interrupting the circuit to effect its deenergization and render the clutch device inactive.
