SHEET FASTENING MEANS Filed Sept. 21, 1942 Patented Apr. 20, 1943 SHEET FASTENING MEANS Harley K. Foote, Chicago, 111., assignmto Foote a Van Wie, Incorporated, Chicago, lll., a corporation Illinois Application September 21, i942, Serial No. 459,217 11 Claims. (Cl. 24-153) This invention relates to means for fastening sheet material and a method for effecting such fastening. More particularly this invention relates to a composite sheet material comprising separate sheets which may be fastened together in co-planar relationship by tongue members formed in one of the sheets.

One object of this invention is the provision of a sheet which is cutand scored in such a manner as to permit a second sheet to be readily attached thereto.

Another object of this invention is to provide means for securing two sheets together in 00- planar relationship in such a manner that they may be rotated with respect to each other in the plane of the sheets.

A further object of this invention is to provide means including tongues and tabs for securing two sheets together without the necessity of using extraneous appliances.

A further object of this invention is to provide a method for securing two sheets together.

A still further object of this invention is to provide a composite sheet assembly which is useful for may purposes including simple card calculators and the like.

Further and additional objects will appear from the following specification, the drawing, and the appended claims.

In accordance with one embodiment of this invention, a first sheet is provided having a plurality of spaced tongues or tongue-like members integral therewith which are capable of being bent upwardly and outwardly in order to embrace an edge of a second sheet to'which it is desired to attach the first sheet. The integral tongue members are associated with integral tab members or tabs which are also cut out from the sheet. The tabs are formed in such a manner that when the tabs are bent out of the plane of the blank sheet the corresponding tongues are lifted out of the plane of the sheet in an opposite direction. As will be hereinafter more clearly pointed out, this feature permits the composite structure of this invention to be readily assembled.

In one form that this invention may take the tabs and tongues are spaced radially so that the tongue members extend outwardly from a central point within th sheet. The thus extending tongue members register with a circular aperture provided in the second sheet and when the second sheet has been placed adjacentthe first sheet with the tongue members extending through the aperture, then the tongue members are capable of being brought into overlying relationship with the inner edges of the second sheet adjacent the aperture. Because of the fact that the aperture is preferably circular in shape and because the tongue members abut closely against the inner edges of th second sheet containing the aperture, the second sheet, although firmly secured to the first sheet, is capable of being rotated in the plane of the sheet about an axis extending through the center of the aperture.

'If desired, an adhesive strip may be placed over the tab portions on that side of the first sheet opposite the side adjacent to which the second sheet has been secured. This adhesive strip prevents the tabs from being bent out of the plane of the sheet and thus tends to hold the tongue members in overlying relationship with the inner edges of the second sheet.

The fastening means briefly described in the foregoing may be used for a number of purposes. However, it is particularly useful for securing an apertured disk of sheet material to a sheet or card. This disk is capableof rotation about an axis perpendicular to the plane of th cardand the composite structure may be useful for form ing simple card calculators which may be very cheaply produced and which may be sold or distributcd as novelties or for advertising purposes. The sheet materials employed in constructing the sheet assembly of this invention may be heavy paper-like material which is capable of being slit, cut and scored, or th assembly may be formed from sheets of plastic material, metal or other composition sheets if desired.

For a more complete understanding of this invention, reference will now be had to the drawing, in which:

Fig. l is a plan view of the composite sheet assembly constructed in accordance with one embodiment of this invention;

Fig. 2 is an enlarged sectional detail view taken along the line 2-2 of Fig. 1;

Fig. 3 is a plan View of a sheet or card which may be used for preparing the composite sheet assembly shown in Fig. 1; and

Fig. 4 is an enlarged sectional detail view taken along the line 4-4 of Fig. 3, showing the tabs and tongues bent out of the plane of the sheet.

Referring now more particularly to the drawing, particularly Figs. 3 and 4, a sheet or card It is formed having a plurality of radially spaced tongues l2 defined by channel-shaped slits I4 formed in the sheet. Associated with each of the tongues H are a plurality of tabs 16 formed by a plurality of radially spaced slits l8 extending outwardly from a common central point. The slits l8 are preferably of equal length and the ends of the channel-shaped slits l4 terminate in a line extending between the ends of adjacent slits l8. The sheet is scored along the lines 20 extending between the ends of the channelshaped slits l4 and the ends of the slits 18, thus permitting the tabs 16 and the tongues l2 readily to be bent out of the plane of the sheet Ill. As 10 best shown in Figs. 1 and 2, a second sheet in the form of a disk 22 is secured to one surface of the blank sheet II) by means of the tongues l2 which have been out of the plane of the sheet "I and extend upwardly and outwardly and overlie the inner edge of the disk 22 adjacent a circular aperture 24 positioned therein.

It will be noted that when the tabs it are bent out of the plane of the blank sheet In along the scored lines 20, the tongues l2 are simultaneously lifted from the opposite surface of the blank sheet It, as shown most clearly in Fig. 4. Inasmuch as the scored lines20 do not extend across the base of the tongues [2, the tongues likewise have a tendency to be forced back into the plane 2 of the sheet Ill when the tabs are bent back into the plane of the sheet. Accordin ly when the disk 22 is positioned as shown in Fig. 2, the tongues [2 press tightly against the inner edges of the disk, holding it firmly in place. Because of the fact that the aperture 24 is circular and the tongues l2 are radially spaced, the disk 22 is capable of being rotated with respect to the sheet Ill about an axis extending through the center of the aperture 24.

In order to prevent the tabs It from being pushed out of the plane of the sheet I!) after the disk 22 has been assembled therewith an adhesive strip 26 is secured to the side of the sheet I. opposite that to which the disk 22 is against all of the tabs l6, causing them to be bent on the opening.

downwardly, as shown best in Fig. 4. This may be done by inserting a rod through the opening provided when the tabs are bentback. These tabs bend along the score lines 2' and simultaneously cause the tongues l2 to lift from the opposite 53 surface of the sheet. The apertured disk 22 is then slipped on over the upstanding tongues i2 and brought into co-planar relationship with the sheet It. (If a rod is used for simultaneously bending all of the tabs, the apertured disk may he slipped on over the rod.) The tabs It are then bent back into the plane of the sheet ll thus forcing the tongues l2 to overlie the inner edges 01 the disk 22 adjacent the aperture 24. A suitable adhesive strip 26 is then placed over the 35 tabs It to lock them in position and to prevent ready displacement of the tongues 12 from their overlying position.

It will be readily seen that the assembly of this invention may be readily constructed and will aperture, the tongues I 2 being so positioned as to prevent substantial bodily movement of the disk horizontally with respect to the sheet [0. While three tongues are shown in the drawing. more may be formed and used if desired. It will be apparent that the construction of this invention may be used for a number of purposes and it may be formed from substantially any typeof' sheet material. Structures wherein the sheet material is prepared from heavy paper stock have been found to be completely satisfactory for most Purposes. The sheets may be printed with suitable figures, letters, or other markings before or after assembly.

While a particular embodiment of this invention is shown above, it' will be understood, of course, that the invention is not to be limited thereto, since many modifications may be made,

and it is contemplated, therefore, by the appended claims, to cover any such modifications as fall within the true spirit and scope of this invention. v
