13e it'known that I, GEORGE H. KAISER, a 'citizen ofthe United States, and a resident '.of Portland, in the county of Multnomah and State of Qregon, have'made certain new and useful 4Improvements in Machines for Making Sanitary Drinking-Cups, of which the following is a specification. y
My invention relates to improvements in devices for making sanitary drinking cups, and it consists in the combinations, constructions and arrangements herein described .and claimed.
An object of my invention is to provide a device to be stationed near the place at which the cups are to be used, the user forming the cup himself preparatory to using it. A further object of my invention is to provide a device of few parts and comparatively simple construction for enabling the operator to., quickly and easily form a drinkmg'cup.
A `further object of my invention is to provide a device having a roller upon which are a series of blanks to be used in making the drinking cups.
Other objects and advantages will lappear 1n thefollowing specification and the novel.
will be particularly features of the device pointed out.
My invention is illustrated in the accom. pan-'ying drawings forming part of this apv plication in which similar .reference characters indicate like parts in the several views, f .lar to the' guide members'19x and 20x ofthe Figure 1 is a sectional view' of the device l and in Whichfrom front to rear, along the line 1 -1 of Fig2, Fig. 2' is a transverse section through;
the device, along-the line 2-2 of Fig. 3, Fig. -3 is a section along the line -3-'3 of 'Fig. 1, and Fig. 4 is a detail vi`ew-` ofthe ratchet mechanism taken on line 4'-4 of ribbon or Vtapeicmposed of a series of cir-v 'I cular portions such as that shown at13 in Fig.4 2. It will be seen thatthese circular portions are connected at their points of tangency-13"., so as to form a `,continuous tape. This tape or ribbon maybe made of thin sheet metal, such as sheet aluminum,
tin, or even.pasteboard or parchment paper.
Referring now to Fig. 1. I have shown therein a cylinder 14 which is fastened to the side 3 and is provided with a spring 15 arranged to bear on a plunger 16 Whichhas at its end aplate 17. .Arranged to slide onl vthe plunger is a cup-shaped mold member 18 which hasa recess 18x for thereception of 'the plate 17. The 'cup-shaped mold menber 18 is provided at its rear end with in-` .tegral laterally extending arms 19 and 20 (see Fig. 3) to which are pivotally attached Iconnecting rods -21 and 22 respectively.
These connecting rods "are secured to the crank shaft 23,the latter being supported upon bearings 24 and 25 and being operated by a handle 26 on the opposite side of the casing. In order to ide the member 18v in Aits movement, I provide the guide blocks 19x and 20 which are'arranged to slide in runways such as that shown at 20y 1n Fig. 3,
these run-ways being formed inthe metal -strips 24 and 25 respectively.
A coperating mold member 261s shown inFigs. 1 and 3. This is provided with a recess 26a and has a bar 27 (see Fig. 3) se-` cured to it. Tlieends of the bar are vided with guide members 28x and 29 Suniarms 19 and 20.- The guide members- 28x that shown at 20?. A connectingrod 30 is pivotally attachedito the rod 27 and to the' central portion of the crank shaft 23. It -Will be noticedthat this central portlon 1s at 180 from theconnections with the rods 21 and 22. A spring32 is attachedto-a pm 33 on the inner side of the side member 5, the opposite end of the spring 32 being secured to an arm 34carried by the shaft 23. Rotatably '-secured between the side ,members '8 and 9 are thel rollers 35, 36, 37 and 38. The.
rollers35 and 36 are. held together -by means of a spring 39 and the shaft 40 of the roller yand 29x also move in run-ways similar to 36 is prolongedto ratchet clutch 41. The
latter is -drlven through ashaf t 42 which passes through the side member 5 and has upon it a handle 43. `A stop member 44 1s provided for thel handle and a s ring 45 on the arm 46 .carried by the ,sha
42 serves to return the handle to itsv original position. At 47 (see Fig. l) I have shown a guide member which also serves as a die for the cutter 48. The latter, as will be seen from Fig.`2, has its cutting edge on the arc of a circle so as to conform with the contour of the circular disks 18. The cutter 48 is secured to a cross bar 49 as shown in Fig. 2.
From the foregoing description of the various parts of the device the operation thereof maytbe readily understood.
The reel 12 is supplied with the blanks 13 and the end of the ribbon is passed between the rollers 35-36 andthe guide 47 and the roller 38. The apparatus is now ready for operation. The voperator first grasps the handle 43 which is resting against the stop 44 and turns the handle clockwise, until it comes into contact with the stop member 31. This causes the tape to be drawn in between the rollers 35 and 36, and the guide member 47 and roller 38 into the position shown in Fig. -1 when t-he circular blank now lies immediately in front of the mold member 18.
On releasing the handle the spring 45 causes the return of the handle until it reaches the.
stop 44. The shaft 40 bears upon it a ratchet 40?, while the shaft,42 is secured to a casing 41 havinga pair of spring-pressed pawls 41x arranged to engage the teeth of the ratchet 40X, lso that when the handlek43 is turned clockwise it will cause the revolution of the shaft 40 through the engagement of the spring pawls 41x with the ratchet 40x. When, however, the handle isreleased, the pawls 41X'will ride idly over the teeth of the ratchet member. .It will thus be seen that the movement of the handle in one direction will cause the plate .to be drawn forward between the rollers while the movement in lthe other direction will have `no effect. The blank now being in vthe position shown in Fig. 1, theoperator turns the handle 26 yand in doing so it causes the crank shaft 23 to revolve, thereby moving the mold member.
18 forwardly and the mold member 26'rearwardly. ,'Ihe movement of the mold member 18 causes the severing of the blank at the connecting edge 13X. The mold member 26 engages the center of the circular blank and presses it against the plate 17 which holds it securely. AA further movement of the two-mold members causes the plate to be pressed into the shape of a cup, with a flat bottom, the plate 17 entering the Vrecess .181 On the releasev of the handle it will return toits normal position bymeans of the 'spring 32.. The plate` 17 which,'during the movement of the two mold members together, was pushed rearwardly against the tension of the spring 15 now returns to its normal position and lin vso doing it pushes the molded cu out of the mold member 18,
whereupon ft alls to the bottom of the casing and may be removed through the opening 7. The device is now ready for molding another cup. It will be seen that I have pro- Vvided a device in which the material from which the c'p is made is kept in a sanitary condition at all times prior to the actual making'and use of the cup. I am aware that sanitary cup devices hav been vmade in which the cups are stacked together, but these devices take up considerable room, whereas, in my device a tape,
provided with blanks sutlicient to make a large number of cups, may be stored in the reel for holding a tape or ribbon, a pair of mold members, means for feeding a portionA of the tape between said mold members,
and means for causing the tape to be pressed betWeen`the mold members.
