2 Claims.'

Thisinvention relates duplicating machines,

and more particularly to an improved device for holding transfer material.

The primary object of the invention is to provide an improved holding blade for a vcarbon or transfer slip that will not catch advancing tionery at the register perforations.

A'further object of the invention is to provide an mprovedform of transfer slip that may be easily anchored to the carbon holding blade and stawill have its corner portions kcut-away with' rela tion to the notches in the carbon blade so that the perforations inthe stationery will not catch or tear the transfer slip. y

The improved transferL slip holding device, while particularly adapted for use in an autographic register, may also be used in an ElliottkFisher machine, a typewriter, or otherduplicating machines using continuous-form stationery. Such kstationery is usually provided with registerl perforations which have a tendency to catch and' tear on interleaved blades or tov catchand tear the rear edge portion of transfer slips anchored between the stationery. The present invention is to avoid these difficulties andprovidegan inexpensive carbon slip which may be readily re-k placed.

The invention is illustrated in a preferred emll so that the blade may be `flexed upwardly and `slipped into position. The blade is provided with a'pair of V-'shaped `notches `I2 which yare rear-l wardly presented and are in alignment with register perforations 1a provided inthe stationery. The carbon or'transfer' slip I3 has a neck pory tion Uly which bridges the distance between the bodiment in the accompanying drawing, in-

Whichy Figure 1 is a broken plan view, partly insecinvention; Figure 2, a view similar to Figure 1 with atop stationery strip removed to vexpose the transfer slip; Figure `3, a broken sectional view, taken asindicated at line 3-3 ofFigure 1; and Figure 4, a plan view'of the holding blade.

In the embodiment illustrated, an autographic tion, of an autographic register embodying the` register 5 is shown with a supply compartment 6 from which stationery strips 'l may be drawn over a writing platen 8,v in the well-known manner. f

A carbon holding blade 9 is preferably made of thin steel and is pivotally mounted at one edge of the platen, as indicated 'at l0. The opposite side of the platen is provided with a loop yor notch notches l2 in the blade.

ywith one edge of the adjacent V-shaped notch I2 in the blade 9.v Preferably the rear end portion of the transferslip ywith-its neck I 4 is uncarbonized `or not covered with transfer material, so thatthe slip may be handledwithout soiling `the operators fingers.r

In thedraw'ing only one carbon slip is shown, but it willvr be understood that additional slips may be provided with supporting blades in superposed relation, if more than tWo stationerystrips are to be used. I

The foregoing detailed description hasbeen given for clearnessof understanding only, and

no unnecessary limitations should be understood therefrom for some modifications willbe obvious to those skilled inthe art.'

I claim: Y p

1. A manifolding device, for continuous-form stationery Lstrips provided with transverse pairs ,of register perforations,l comprisingaa thin resilient blade',' adapted to beinterleaved betweeny the stationery strips, and havinga pair of rearwardly presented V-shaped notches in alignment l with the register'perforations in the stationery:y

and a duplicating Aslipextending forwardly 'inin- .terleaved `relation with the stationery and having a narrowedjreanend portion folded over said blade between said notchesto anchor the slip# against advancement with the stationery.

2. A device as specifiedin claim 1, 'n which the folded anchoring portion ofthe carbon strip is of a width equal tothe distance between the V-shaped notchesr and eachrear corner. portion of the duplicating-slip is cut-away on a biased `line yforming-a prolongation` of` one edge of the" adjacent V-shaped notch in the holding blade. LOUIS JENSEN.

The corner portions*A Y kl5 are cut-away on a bias which is in alignment
