CONTINUOUS-FORM STATIONERY I Filed May 17, 1943 Patented July 4, 1944 CONTINUOUS-FORM STATIONERY Gregson L. Barker, Chicago, Ill., assignor to United Autographc Register Co., Chicago, Ill.,

This invention relates to continuous-form stationery and more particularly to an improved fastener, made of the paper itself, for holding the strips together.
The primary object of the invention is to provide a simple and inexpensive fastening for long strips of continuous-form stationery, which may be interleaved with carbon strips or other transfer material, which will not interfere with the feeding of the stationery through business machines and will not have thread, staples, or the like which might become detached and fall into the writing machine.
A further object of the invention is to provide a fastener for continuous-form stationery which may be provided with feeding apertures and to position the integrally formed improved fastener so that portions of the strip which are out away to form the fastener will leave openings which may also serve as feeding apertures.
Continuous-form stationery is well known in the art and it has been common to connect the superposed strips by various means, such as staples, sewing, glue, and the like. However, such stationery is commonly used in large and expensive typewriting machines and if a staple or piece of thread happens to come loose, it may drop into the machine and interfere with its operation. Glued forms do not permit any relative movement between the strips and form hard portions which are diflicult to feed around acircular platen. It has heretofore been proposed to connect superposed continuous-formed strips by cutting V shaped notches and pressing the tongues upwardly or downwardly. However, as the tongues were not interlocked, the strips became detachable.
In the present invention tongues are partially cut from the paper, are reversely folded and their free ends projected through an adjacent set of slots so that the strips are securely held together at all times. This particular form of fastening has been used to secure letter size sheets together but as far as applicant knows, it has never been used in connection with continuous-form stationery or with stationery having feeding apertures in the manner proposed by applicant.
'Ihe invention is illustrated in a preferred embodiment in the accompanying drawing in which- Fig, l is a plan view of a manifold assembly provided with the improved connections: Fig. 2 is an enlarged fragmentary view showing the particular fastener employed; and Fig. 3 is a fragmentary sectional view taken as indicated at line 3 of Fig. 2.
In the embodiment illustrated superposed strips of record stationery 4 are provided with forms having lines of weakening 5 between forms so that after a set of forms has been filled in, they may be readily detached. Usual carbon strips 6 may be provided and preferably the assembly is provided with a longitudinally extending detachable marginal strip 'l in which the fastening means is located.
If desired, the stationery may be punched at the time it is printed as indicated at 8 and these perforations used in assembling the various strips into proper registration before they are interlocked together. After the strips have been brought in the superposed relation, a cut is made through the assembly as indicated at 9 and the tongues lil which are thus formed are folded downwardly and then projected up through a slot Il and the free ends I2 are folded over the uppermost strip towards the bottom of the form. By this arrangement the free ends of the tongue will not catch on parts of the writing machine and interfere with the advancement of the stationery. This connection may be performed very quickly by machines known in the art. Subsequently, if desired, the stationery may be fed through a perforating machine and marginal perforations l 3 or other desired perforations may be made. During this operation the form is kept in proper alignment by means of the apertures 8 and the holes cut to form the tongues l0 are positioned so that the opening may also serve as one of the feeding apertures.
After the forms have been filled in on the machine, and it is desired to separate the various sheets, this may be done by pulling off the detachable margin 1, along a longitudinal line of weakening I l.
The foregoing detailed description has been given forclearness of understanding only and no unnecessary limitations should be understood therefrom for some modifications will be obvious to those skilled in the art.
1. Continuous-form stationery comprising: a plurality of superposed strips of record forms provided with interleaved transfer material, said strips being interlocked together by tongues partially cut at regularly spaced intervals from the strips and folded together and impaling adjacent superposed slots in all of said record strips, the openings left by said tongues being adapted to serve as feeding apertures.
2. Stationery as specied in claim 1, in which the tongues project through the slots positioned so that the free ends of said tongues are above the uppermost strip and are directed rearwardly when the strips are advanced into a writing machine.
3. Continuous-form stationery comprising; a plurality of superposed strips of record forms provided with detachable marginal portions having feeding apertures at regularly spaced inter- 10 vals, said strips being interlocked together by tongues which are partially cut from the detachable marginal portions and reversely folded and projected through adjacent superposed slots in all of said record forms, said tongues being disposed entirely between said feeding apertures, and the openings left by said tongues being positioned to serve as regularly spaced feeding apertures.
