- the lower edge of th die 36 is formed with an inner annular recess 49 and below this recess with another annular recess 50 which is of greater diam eter than the recess 49 and at the upper edge of which is formed a'shoulder 51.
- the cutting edge 38 is at the lower edge of the recess 50.
- the lower portion of the'cutting die 36 is adapted to the construction of the upper edge of the female die 48, which has a thin portion 52, over which the recess 49 passes when the die 36 is moved downwardly, and the folded over upper edge of the paper in the cup formation lies along the outer side of the said portion 52 and within the recess i the actuating lever 23 and frame '22 is that Y H shown by solid lines in Fig. 3.
- Fig. 3 illustrated in Fig. 3 by dotted lines and the final operated position of said parts is that
- the reel of paper from which the cups are to be formed is held in a casing 54 below the bed-plate 15, and the casing 54 will preferably have downwardly convergingbottom sections so that the reel of paper may be cen- L tralized and left loose within said casing.
- the strip of paper from the reel 30 is extended upwardly through an opening or slot 55 in the bedplate 15 and then passed between two rollers, preferably rubber faced, 56. 57, which extend'transversely across the machine and are mounted in suitable bracket arms 58 extending forwardly from the end standards 17, 20.
- the roller 57 is driven and by its pressure toward the roller 56' rotates said roller so that both rollers rotate against each other for the purpose of drawing the paper strip forwardly over 'a suitable table 59 provided above the bed-plate 15.
- the roller 57 is driven or given its proper rotary movement by means of a segment 60 secured on the shaft 21 and adapted'at the proper time to engage a pinion 61 which is loose on the shaft 62 of the-roller 57, and said pinion wheel 61 is rigid with a ratchet wheel 63, which is engaged by apawl 64 pivotally held on a disk which is rigidly secifred on the said shaft 62 of the roller 57.
- a segment-60 is moved downwardly from the dotted position shown in Fig.
- the first step in the operation'of the machine when the actuating lever 23 is pulled downwardly is thatperformed by the segment 60 in feeding forwardly overthe table 59 and female die 48 'just the requisite 'section or length of the paper for one cup, and immediately thereafter and after the segment 60 has left the pinion wheel 61 and the rollers 56, 57 are statlonary, the presser arms 27 descend against the cutter bar 28 for cutting off the section 29 of the paper, said cutterbar 28 carrying a knife 66 which descends through the paper and into a slot 67 in the table 59, and, said blade cpoperating with the upper edge of the table 59 at the slot 57 to cut off the paper smoothly.
- the paper during its movement is guided by the longitudinal guides 68 formed of sheet metal and bein located at each'edge of the path of the strip, as shownin Fig. 4.
- the guides 68 constitute a portion of a sheet metal frame at whose inner end is a transverse section 69 connecting the guide members 68 and below which the paper is caused to travel.
- the sheet metal of said transverse connecting section 69 is flared upwardly, as shown in Fig! 1 so as to serve as an effectual entrance slot for the end of the paper fed forwardly by the rollers 56, 57, and said section 69 is slotted in line with the aforesaid slot 67 so as to provide for the descent of the blade 66 through the paper.
- the cutter bar 28 is a plain transverse bar carrying the blade 66 and mounted at its ends between vertical guides 70 and upon coiled springs 71 which serve to move the bar 28 upwardly to its initial position after the presser arms 27'have receded upwardly from the same.
- the ends of the bar 28 areprovided-withslots 72 (Fig. 7) to receivepins 73 extending into/them from the vertical uides 70, saidkslots and pins serving to limit the movement of said bar.
- the ratchet bar 75 prevents an upward movement of the frame 22 after said frame has started downwardly, and the ratchet bar 74 prevents a downward movement of said frame 22 after the same has been started upwardly.
- the casing 81 is of rectangular outline and will enclose as much of the machine as may be expedient so as to protect, as far as possible, the operative parts from dust or Theroll ofpaper is well protected by the casing 54, and it will be seen that only enough paper for one cup is exposed over the die 48 and that it only becomes exposed when a cup is to be immediately formed therefrom.
- the paper is not handled manually at all after it has once been introduced to the machine, and the finished cup may be removed from the machine by the hand of the person desiring to use it.
- I number the cup 87 and the downwardly pressed lip around the mouth thereof is in- .dicated by the number 88.
- the operation of the machine will largely be understood from thedescription hereinbefore presented, and hence but slight further explanation of such operation is necessary.
- the initial position of the frame or arm 22, actuating arm 23 andsegment 60 is indicated by dotted lines in Fig. 3.
- the paper from the reel 30 has its free end caught, between the rollers 56, 57,and when it is desired to form a cup the operator will pull downwardly on the frame 22 and arm 23 and this will result in the said arm 23 and frame 22 turning downwardly and forwardly, with the result that the segment 60 will be carried against the pinion wheel 61 and cause the rollers 56, 57 to feed forwardly between the guides 68 asufficient length of the paper, which may be called a section 29, across the female die 48 for the formation therefrom of one cup.
- the segment 60 leaves the pinion-wheel 61 before the frame 22 and arm .23 have completed their downward movement, and after the segment 60 passes from engagement with the pinion-Wheel 61,
- the presser arms 27 descend against the cutter bar 28 and the knife blade 66 severs the section 29'of paper at the slot 67 in the bedplate or table 59.
- the continued downward movement of the actuating arm 23 results in the male die 41 being pressed downwardly against the paper section 29 and forcing the paper into the female die 48, the edge portions of the paper standing upwardly above said female die, as indicated by dotted lines in Fig.
- the body portion of the male die tapers downwardly and is adapted to fitwith reasonable closeness within the female die 48, whose side walls extend downwardly on cohverging lines, and due to the formation of said male and female dies that portion of the paper which projects upwardly above the die 48, as shown by the dotted lines in Fig. 9,
- the operation is a simple one and only requires, after the paper 30 is in position, one complete downward movement of the frame 22 and actuating arm 23 to feed the length of the paper across the female die, cut off that length. depress the paper into the female die 48 and form the lip 88 on the cup and trim the edges of the paper around said lip. It has already been explained that when the frame 22 is started downwardlyit is compelled to have acom- .plete downward movement before it starts upwardly again and that after the said frame has been started upwardly, said frame must be carried to its extreme upper position before it can be started downwardly again.
- the coin-controlled mechanism may or may not be used, as may be preferred.
- the machine is small, comparatively inexpensive to build, sanitary and adapted to be usedby the owner for making a cup at any time a cup should be desired.
- a female die over which paper for a cup may be placed, a male die for forcing the paper into said female die and leaving a part of the paper projecting upwardly around the edges of the same.
- a cutting die around the upper portion of said male die adapted to engage said upwardly projecting portion of the paper and fold the same downwardly around the upper end of the female die to form a lip on the cup and cut off the surplus portion of the paper around said lip.
- a spring interposed between said male die and cutting die and permitting said cutting die to have an independent movement imparted to it for forming said lip and cutting off the surplus portion of the paper after the male die has become seated in said female die, and means for effecting the operation of said male and cutting dies.

Application filed November 7, 1918, Serial No. 261,445. Renewed December 13, 1921. Serial No. 522,145.
' To all whom it may concern:
'Be it known that I, CHARnns S. BATDORF, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machines for Making Paper Cups, of which the following is a specification.
The invention relates to the manufacture of paper cups, such as are used for drinking and other purposes, and it consists in the novel features, organization and structure hereinafter described and claimed.
One object of my invention is to provide a reasonablysmall an d comparatively inexpensive machine capable of use by the owner thereof for making a paper cup at anytime such cup might be desired. One special purpose accomplished by the invention is the fact that the paper after' having been introduced in the form of a reel to the machine, does not require to be handled at all and is protectedas far as possible from contamination of any kind. The machine comprises a female die, means for feeding a proper length of the paper across the a same, means for cutting off such length fromthe body of the strip, a male die for driving the paper into the female die and a cuttingdie for turning over the upper edges of the paper and trimming off the surplus portions of the paper around the lip of the cup. The strip of paper wound into a reel is delivered bodily to the machine and is not again touched by the human hand, but confined within a closed casing,
and the lengths for the separate cups are fed from this strip, and one feature of my invention is that with my machine I may employ a strip of paper of uniform width, such as may be easily made, in lieu of employing paper blanks which have been cut by dies and handled before-being delivered to the machine. One (if my aims is to produce a-machine and manufacture cups thereon withoutthe paper or the cups becoming contamlnated in any way. Vhen a cup has been made it may be removed from the machine by the hand of the person desiring to use it.
' Theinvention will be fully understood from the detailed description hereinafter presented, reference being had. to the accompanying drawings, in which:
Fig. 1 is a vertical longitudinal section through a machine constructed in 3.600. 1
ance with and embodying the invention, the mechanism being shown in a partly operated position with the requisite length of paper.
fed across the female die and cut from the body portion of the paper and the male die as having reached a position preparatory to driving the cut off section of the paper into said femaledie;
Fig. 2 is a detailed side elevation, partly broken away and partly in section, illustrating the mechanism for compelling a full down stroke and a full up stroke of the mechanism connected with the male die features;
Fig. 3 is a view corresponding substan-' tially with Fig. 1, but illustrating the final operation of the mechanism in the formation of a cup and prior to the male die 'fea-' tion of the machine, taken on the dotted'line 55 of Fig. 4 and illustrating more articularly the coin mechanismrequired, w en desired, for the operation of the machine;

Fig. 9 is a vertical transverse section through the cup formed on the machine,- the dotted lines indicating the upper edges of the paper formation prior to the same being folded outwardly and downwardly and trimmed, and V Fig. 10 is a side elevation of the completed ating lever 23, the frame22 being rigid with n the drawings, 15 designates a suitable Upon the rear end of the the shaft 21 and the operating lever 23 being pivotally mounted on'said shaft. The frame 22 comprises two arms 24 integral at their front ends with a sleeve or collar 25, and the operating lever 23 is disposed between the arms 24 and during a portion of the operation of the machine moves therewith, while during another portion of the opera tion of the machine the lever 23 has a movement independent of the frame 22, said frame then being stationary. Upon the members 24 downwardly projecting presser arms 27, which, as hereinafter explained, are utilized 1n connection with a cutter bar 28 for cutting off the proper sections 29 of pa-- per from the body portion 30 of the paper for the formation of a cup, and the frame 22. is formed at the hub of one of its members 24 with stop lugs 31, 32 adapted to engage a pin 33 on the standard 18 for arresting said frame 22 in its two positions, the lug 31 engaging said pin when the frame 22 is in its upper initial position indicated by dotted lines in Fig. 3 and the lug 32 engaging said pin when said frame 22 reaches its lower position indicated by solid lines in Fig. 1.
The actuating lever 23 is swiveled on the shaft 21 and has an operating handle 34 by which said lever may be manually operated, and at the rear of the handle 34 said actuating lever 23 is formed with a ring or band 35 which encompasses a cutting die 36 of inverted cup form and having a shank 37 which extends through an opening in the sleeve or collar 25 formed on the front end of the frame 22. Thedie 36 has a lower cut ting edge 38 and it is connected with the ring or band 35 by means of studs 39 on the sides thereof entering slots 40 in the sides of said ring or band 35, as may'be clearly understood on referenceto Figs. 1, 4 and 8.
The cutting die 36 carries a plunger or male die 41 whose body portion represents the interior outline of the cup to be formed, and said plunger for male die 41'is connected with the cutting die 36 by means of pins 42 extending laterally from the upper side portions of said plunger or male die 41 and confined within vertically elongated slots 43 formed in the' sides of said cutting die 36. The plunger or male die 41 is formed or pro vided at its upper end with a central vertical stem 44. which projects upwardly into. a
of the slots 43.
. illustrated in Fig. 3 by dotted lines and the final operated position of said parts is that The reel of paper from which the cups are to be formed is held in a casing 54 below the bed-plate 15, and the casing 54 will preferably have downwardly convergingbottom sections so that the reel of paper may be cen- L tralized and left loose within said casing.
The strip of paper from the reel 30 is extended upwardly through an opening or slot 55 in the bedplate 15 and then passed between two rollers, preferably rubber faced, 56. 57, which extend'transversely across the machine and are mounted in suitable bracket arms 58 extending forwardly from the end standards 17, 20. The roller 57 is driven and by its pressure toward the roller 56' rotates said roller so that both rollers rotate against each other for the purpose of drawing the paper strip forwardly over 'a suitable table 59 provided above the bed-plate 15. The roller 57 is driven or given its proper rotary movement by means of a segment 60 secured on the shaft 21 and adapted'at the proper time to engage a pinion 61 which is loose on the shaft 62 of the-roller 57, and said pinion wheel 61 is rigid with a ratchet wheel 63, which is engaged by apawl 64 pivotally held on a disk which is rigidly secifred on the said shaft 62 of the roller 57. \Vhen the segment-60 is moved downwardly from the dotted position shown in Fig. 3, it engages the pinion wheel 61 and rotates the same, and the motionof said wheel is communicated by the ratchet wheel 63 to the pawl 64 and disk 65, with the result that the shaft 62 and roller 57 will be rotated and aproper section 29 of the strip of paperwill be fed forwardly over the table 59 andacross the. top of the female die 48. On the upward movement of the segment60from its position shown by full lines in Fig. 3 to that illustrated by dotted lines in Fig. 3, said segment will again engage the pinion wheel 61 and at this time the ratchet wheel 63 will ride below the pawl 64 without communicating its motion to the disk 65 or shaft 62, this arrangement being for the purpose of permitting the rollers 56, 57 to stand idlewhile the operative mechanism is being returned to its initial position, shown by dotted lines in Fig. 3.
The first step in the operation'of the machine when the actuating lever 23 is pulled downwardly, is thatperformed by the segment 60 in feeding forwardly overthe table 59 and female die 48 'just the requisite 'section or length of the paper for one cup, and immediately thereafter and after the segment 60 has left the pinion wheel 61 and the rollers 56, 57 are statlonary, the presser arms 27 descend against the cutter bar 28 for cutting off the section 29 of the paper, said cutterbar 28 carrying a knife 66 which descends through the paper and into a slot 67 in the table 59, and, said blade cpoperating with the upper edge of the table 59 at the slot 57 to cut off the paper smoothly.
The paper during its movement is guided by the longitudinal guides 68 formed of sheet metal and bein located at each'edge of the path of the strip, as shownin Fig. 4. The guides 68 constitute a portion of a sheet metal frame at whose inner end is a transverse section 69 connecting the guide members 68 and below which the paper is caused to travel. At the front of the blade 66, the sheet metal of said transverse connecting section 69 .is flared upwardly, as shown in Fig! 1 so as to serve as an effectual entrance slot for the end of the paper fed forwardly by the rollers 56, 57, and said section 69 is slotted in line with the aforesaid slot 67 so as to provide for the descent of the blade 66 through the paper.
The cutter bar 28 is a plain transverse bar carrying the blade 66 and mounted at its ends between vertical guides 70 and upon coiled springs 71 which serve to move the bar 28 upwardly to its initial position after the presser arms 27'have receded upwardly from the same. The ends of the bar 28 areprovided-withslots 72 (Fig. 7) to receivepins 73 extending into/them from the vertical uides 70, saidkslots and pins serving to limit the movement of said bar.
Since it is one purpose of this invention to provide" for the accurate feeding of one section 29 of paper fora cup at the commencement of each down stroke of the frame 22 and actuating. lever 23, it is desirable that when said frame and lever are moved,there should be a complete down stroke and a complete up stroke thereof, and to this end I provide means for preventing the return of the frame 22 and lever 23 after the same have started downwardly until they have completed their full movement and likewise I provide means wherebywhen said frame and lever have been started upwardly to their initial position shown by dotted lines in Fig. 3 they must be returned absolutely to such position before they can be started downwardly again; and the means I provide for accomplishing these purposes are more particularly illustrated in Figs. 2, 4 and 7 and comprise a stationary ratchet bar 74 secured against the standard 17, a ratchet bar 75 pivotally secured to said standard and a pawl 76 which is pivotally secured to a disk 77 which is rigid on the shaft 21. When the 'frame 22 and lever 23 are started downwardly, the pawl 76. will ride up the ratchet bar 75'and will not leave said ratchet bar, by dropping over the front end of the same, until about the, end of the down stroke of the frame 22 and lever 23, at which time the pawl 76 will fall from over the forward end of the ratchet bar 75 and enter into engagement with the ratchet bar 74, as T indicate by dotted lines in Fig. 2. Upon the upstroke of the frame 22 and actuating lever 23, the pawl 7 6 will ride up the ratchet bar 74 until it has attained the dotted position in which it is indicated at the upper end of said bar, in which position it will lock the frame 22 in its initial position. The frame 22 can not be returned downwardly until after it has reached its initial position because of the engagement of the pawl 76 with the bar 74. I pivot the bar 75 so that as the frame 22 is reaching its initial position, the pawl 76 may ride under and lift said bar 75 so that the pawl may reach its position shown by dotted lines at the right hand. side of Fig. 2.
The ratchet bar 75 prevents an upward movement of the frame 22 after said frame has started downwardly, and the ratchet bar 74 prevents a downward movement of said frame 22 after the same has been started upwardly.
It may-be desirable to apply to the machine means by which it can only be operated on the introductionof 'a proper coin to pay for the cup to be made, although my invention is not limited to the application thereto of any such coin controlling mechanism. I, however, illustrate suitable means whereby the shaft 21 cannot be operate-d from the frame 22 until a proper coin has been introduced to said shaft. In Figs- 4 to 7 inclusive I illustrate the coin controlled mecha cess 83 formed in the shaft 21 to receive the detent of said dog, an arm 84 extending laterally from the free end of the dog 82 and lying ad aQent to the entrance to the coin I other contamination.
The casing 81 is of rectangular outline and will enclose as much of the machine as may be expedient so as to protect, as far as possible, the operative parts from dust or Theroll ofpaper is well protected by the casing 54, and it will be seen that only enough paper for one cup is exposed over the die 48 and that it only becomes exposed when a cup is to be immediately formed therefrom. The paper is not handled manually at all after it has once been introduced to the machine, and the finished cup may be removed from the machine by the hand of the person desiring to use it.
I number the cup 87 and the downwardly pressed lip around the mouth thereof is in- .dicated by the number 88.
The operation of the machine will largely be understood from thedescription hereinbefore presented, and hence but slight further explanation of such operation is necessary. The initial position of the frame or arm 22, actuating arm 23 andsegment 60 is indicated by dotted lines in Fig. 3. The paper from the reel 30 has its free end caught, between the rollers 56, 57,and when it is desired to form a cup the operator will pull downwardly on the frame 22 and arm 23 and this will result in the said arm 23 and frame 22 turning downwardly and forwardly, with the result that the segment 60 will be carried against the pinion wheel 61 and cause the rollers 56, 57 to feed forwardly between the guides 68 asufficient length of the paper, which may be called a section 29, across the female die 48 for the formation therefrom of one cup. The segment 60 leaves the pinion-wheel 61 before the frame 22 and arm .23 have completed their downward movement, and after the segment 60 passes from engagement with the pinion-Wheel 61,
the presser arms 27 descend against the cutter bar 28 and the knife blade 66 severs the section 29'of paper at the slot 67 in the bedplate or table 59. The continued downward movement of the actuating arm 23 results in the male die 41 being pressed downwardly against the paper section 29 and forcing the paper into the female die 48, the edge portions of the paper standing upwardly above said female die, as indicated by dotted lines in Fig. 9, and thereupon the continued downward movement of' the arm 23 independently of the frame 22 effects the downward movement of the cutting die 36 against the upwardly projecting portions of the paper around the top of the die 48, and this results in said projecting portions of the paper being folded down around the upper edge of the female die 48 to form the lip 88 around the cup and ,in the surplus portions of the paper being cut off soas to leave a lip 88 having a uniform edge. In Fig. 3 I show the cutting die 36 in its lower .position. The body portion of the male die tapers downwardly and is adapted to fitwith reasonable closeness within the female die 48, whose side walls extend downwardly on cohverging lines, and due to the formation of said male and female dies that portion of the paper which projects upwardly above the die 48, as shown by the dotted lines in Fig. 9,
. also flares outwardly and permits the entrance to the inner side thereof .of the lower portions of the cutting die 36, which portions perform the duty as aforesaid of folding the said projecting portion of the paper outwardly and downwardly and cutting the surplus therefrom. The surplus paper in the sides of the cup is flattened or plaited' against the walls of the die 48. After the cup has been formed, the spring 46 which becomes compressed during the said independent movement of the arm 23, will, upon pressure being relaxed from the handle 34, move the cutting die 36 upwardly, and thereafter the arm 23 may be restored to its initial position, carrying the several operative parts to the position shown by dotted lines in Fig. 3. The finished cup may then be removed from the die 48. The operation is a simple one and only requires, after the paper 30 is in position, one complete downward movement of the frame 22 and actuating arm 23 to feed the length of the paper across the female die, cut off that length. depress the paper into the female die 48 and form the lip 88 on the cup and trim the edges of the paper around said lip. It has already been explained that when the frame 22 is started downwardlyit is compelled to have acom- .plete downward movement before it starts upwardly again and that after the said frame has been started upwardly, said frame must be carried to its extreme upper position before it can be started downwardly again. The coin-controlled mechanism may or may not be used, as may be preferred. The machine is small, comparatively inexpensive to build, sanitary and adapted to be usedby the owner for making a cup at any time a cup should be desired. I have described the machine as being used for mak flared outwardly around the edges of the' same, a cutting die around the upper portion of said male die adapted to enter within and engage said upwardly projecting portion of the paper and fold the same downwardly around the upper end of the female die to form a lip in the cup and cut oil the surplus portion of the paper around said lip, and means for effecting the operation of said male and cutting dies.
