Description

CARBON HOLDING DEVICE Filed Oct. 31, 1945 Patented May 4, 1948 CARBON HOLDING DEVICE Lester K. Fleischmann, Chicago, 111., assignor to Standard Manifold Company, Inc., a corporation of Illinois Application October 31, 1945, Serial No. 625,881
Claims. (Cl. 197-126) This invention relates to a carbon holding device for a typewrlting machine adapted to use continuous form stationery.
The primary object of the invention is to provide a simple and improved device for supporting a supply of carbon, which may be in the form of individual rolls of carbon between the strips of stationery, in such a way that the lower strips of stationery and carbon rolls do not have to support the weight of the superposed manifolding material.
Another object of the invention is to provide a separate cantilever support for each roll of carbon, but permitting the individual supporting frames to be swung upwardly for clearance when unwinding carbon from the rolls.
The invention is illustrated in a preferred embodiment in the accompanying drawings, in which- Figure 1 is a plan view of a device embodying the invention; Fig. 2, a rear elevational view of the same; Fig. 3, a sectional view, taken as indicated at line 3-3 of Fig. l; and Fig. 4, a View similar to Fig. 3, but showing a modified form of support.
In the embodiment illustrated, a rigid carrying member 5 is adapted to be attached to the carbon carriage of a typewriting machine, in place of the usual carbon holding blades. The carrying member is provided with upwardly extending standards 6, which afford journals for carbon-roll supporting frames 1.
The carbon-roll supporting frames may be made of wire and are provided at their rear ends with outwardly extending trunnions 8, which are journalled in holes provided in the members 6. Preferably, the supporting frames 1 have at their forward ends a cross bar 9, which is adapted to fit into the center of a flat roll of carbon paper. The frames are also provided with a cross bar It, around which strips of carbon are led from the carbon roll before being extended forwardly to the platen of the typewriting machine.
In order to support the frames in horizontal position, as shown in Figs. 2 and 3, a series of studs II are slidably mounted in openings in the members 6, and are connected at their outer ends by a bar l2 provided with a knob l3. As the studs are located in front of and slightly below the pivots of the carbon-roll supporting frames, they serve to limit the downward swing of the frames and form a cantilever support for carbon rolls mounted on the members 9. When it is desired to unwind fresh carbon rolls, the
studs ll may be pulled out laterally by means of the knob l3 and the upward swing of the three carbon holding frames, it will be understood that as many can be provided as needed to provide carbon in interleaved relation with the strips of manifold stationery.
In the modification shown in Fig. 4, the carbon supporting frames 1 have an integral rearward extension 14 from the trunnion 8. In this form, the studs 15 are slidably mounted in the uprights 6 above and. in rear of the pivots for the supporting frames, so that downward swing of the frames from a horizontal position is prevented. These studs may be withdrawn laterally, when it is desired to swing the frames upwardly.
The foregoing detailed description is given for cleamess of understanding only, and no unnecessary limitations should be understood therefrom, for some modifications will be obvious to those skilled in the art.
I claim:
1. A carbon holding device for a typewriting machine, comprising: a rigid carrying member adapted to be secured to a typewriting machine in rear of the platen; a lurality of carbon-roll supporting frames pivotally mounted on said carrying frame so as to swing upwardly and extending forwardly towards said platen; and supporting means for limiting the downward swing of said frames so as to support them individually, cantileverwise, in interleaved relation with manifold stationery led through the carrying member.
2. A device as specified in claim 1, in which the supporting means comprises withdrawable studs slidably mounted in the carrying member and adapted to extend into engagement with the supporting frames.
3. A device as specified in claim 1, in which the supporting means comprises withdrawable studs.
slidably mounted in the carrying member and adapted to extend into engagement with the supporting frames in front of and below the pivotal connections with the carrying member.
4. A device as specified in claim 1, in which the supporting means comprises withdrawable studs slidably mounted in the carrying member and adapted to extend into engagement with the supporting frames in rear of and above the pivotal connection with the carrying member. 7
5. A device as specified in claim 1, in which the supporting means comprises a slide member on the carrying member having a plurality of studs xtending inwardly to engage each of the supporting frames adjacent to their pivots.
LESTER K. FLEISCHMANN.
