MANIFOLDING ATTACHMENT FOR-TYPEWRITERS.
Application filed January 29, 1923, Serial The object of my invention is to provide a manifolding attachment which can be easily and quickly applied to the platen carriage of a typewriter without any alterations or adjustments and as readily removed at any time. Generally speaking, manifolding on the platen carriage ready for delivery of the manifolding ribbon to its working position and almost instantly detached from the carriage when the manifolding operation is completed or when, for any purpose, it is desired to remove the attachment from the machine. s
Other objects ofthe invention will appear from the following detailed description.
The invention consists generally in various constructions and combinations all as hereinafter described and particularly pointed out in the claims.
In the accompanying drawings forming part of this specification,
Figure 1 is a plan view of-a typewriter platen carriage with my invention applied thereto; 4
Figure 2 is a sectional view on the line 22 of Figure 1 showing the manifolding ribbon in its raised non-working position; Figure 3 is a similar view.showing the 5 ribbon moved down to its working position; Figure 4 is an end view of the attachment; Figure 5 isa sectional view on 55 of Figure 4;
Figure 6 is a plan view of theattachment removed from the machine; V
Figure 7 is a front View; the Working position of the ribbon being indicated in dotted lines;
Figure 8 is a perspective view showing the preferred manner of mounting the workin ribbon and the non-working or guar ribbon;
Figure 9 is a perspective view showing in detail the preferred manner of connect- 'ing the attachment to the frame of the platen carriage.
-In the drawings, 2 represents the end rails of the platen carriage; 3, the machine platen; 4, the typewriter ribbon, and 5, the
the line No. 615,647. Renewed. October 19,1928.
spools on which the ribbon is wound, all of any ordinary or preferred construction;
My attachment comprises end bars 5 preferably of flattened material, adapted to rest upon the top of the rails2, and having holes 2 to receive the screw heads 2 which prevent the bars from sliding endwise on the carriage. Springs 6, flattened in form, are seated upon the top of the bars 5, and clips 7 are mounted on these springs to extend down outside the rails 2 of the platen carriage and have inwardly turned lower ends 8 which snap under the lower edges of the rails 2 and firmly hold the attachment in place on the platen carriage, while allowing it to be easily and quickly separated therefrom by springing the clips 7 outwardly away from the engaging rails of the platen carriage.
Upon the bars 5, upwardly extending standards 9 are mounted, preferably hollow and forming vertical guides for rack bars 10. A shaft 11 has hearings in said standards and gears 12 are mounted on said shaft to mesh with the teeth of the rack bars 10, said shaft projecting outwardly beyond said standards and having finger grips 13 by meansof which said shaft ma be rotated and the rack bars 10 raised or lowered in their guideways as desired.
The lower ends of the rack bars are provided with depending arms 14 having longitudinal slots 15 therein forming fingers 16 and 17. The fingers 16 are connected across the attachment by a flexible stationary ribbon 18 which is not mounted for longitudinal movement but is intended as a guard to prevent the manifolding ribbon proper from contacting with and smearing the rear surface of the sheet of paper upon which the type of the machine is operating. This ribbon is preferably connected to the arm 16 by forming loops in its ends through which the depending fingers are inserted; the ribbon moving vertically with the rack bars between its working and non-working positions and at all times lying between the printing ribbon and the rear face of the original sheet of paper in the machine. 19 represents the printing ribbon which is stretched between arms 14 to register with the ribbon 18 and is carried around the arm 17 and from thence to small pulleys 20 and spools or reels 21 which are mounted on the bars 5 and have suitable cranks 22 bylmeans of which the ribbon may be moved from one spool or reel to the other and thereby pre sent fresh or new surfaces to the action of the type. To hold this prefer to provide jaw'clips23, pivoted at 24 on the lower ends of'the arms 17 and adapted to straddle the-arms and: clamp the printing ribbon thereon, holding it securely in its working position and preventslippage thereof while the device is in'use.
The normal position of the ribbon when,
the attachment is mounted on the machine is indicated .in Figure 2, the ribbonbeing horizontal, and in this position the shifting operation of' the ribbon is performed.
This Figure 2 also illustrates the original page or sheetfof the workindicated by numeral 25 and the page or sheet 26 upon which the carbon copy or duplicate 'is to be rinted. These sheets will be separated.
I as indicated in Figure 2 and the operator desiring to make a manifold copy will manipulate the shaft 11 and lower the manifolding ribbon to its working position opposite the typewriter ribbon 4. This movement of the manifolding ribbon will interpose the guard ribbon 18 between it and the back of the original sheet, preventing smearing thereof, while the manifolding ribbon will be in position to pression of the type upon the surface of the manifolding or duplicate sheet of paper 26' when the keys are operated. This duplica tion will continue as long as desired or until the operator manipulates the shaft 11. in the other direction and raises the manifolding ribbon to its upper or non-working position.
- the As heretofore stated, theshifting of the manifolding ribbon is accomplished in this raised position, as obviously it would not be practicable to move it longitudinallywhen in the position shown in Figure 3 owbeing on a different level ingto the spools than the working section of (the ribbon. Whenever desired, the operator may grasp finger grips 27 and detach the device from the platen carriage.
I claim as my invention: 1 A manifolding attachment for typewriters placed upon a typewriter. platen carriage,
and comprising bars having flat under surfaces for fitting the flat upper surfaces of the end rails of saidcarriage, spring clips mounted on said bars and having inwardly turned lower ends to engage the lower edges of the end rails of said carriage for temporarily holding said bars and carriage together, a manifolding ribbon, and means for moving said ribbon up and down in a vertical plane to its working and non-working positions.
