"This invention relates to the art of bind ing calendars, hangers, banners and the like a metal bindin and tosuch bindings and" method 'ofmaking the same.

-It thepractice in binding such articles to u'se-a; previously formed V-shaped strip of sheet metal which is applied to one edge of the a'rti cle and thenlattached thereto by ahand brake 'or "other suitable device for thejp'urpos'e'ij. orderl'to enable the bound article to be snspended, the binder inserts a" 'Iiietal tab aaahe form of an eyelet in the.

biiidihg :j'strip prior to the operation "of the hand brakeandi this operation serves to attachfthetab. f

' In thus incorporating aloos'e tab, it frequently happensthat the tab assumes an angular position or otherwise becomes misplac ed with" the'res'ult thatfthef mounting is defe'ctive, or the operator may forget to Insert a tab andthus there is no means of suspendingtheicalendar after the binding is completed. In any case, considerable t me isexp'ended during the binding operation In pickingup the tabs "and manually placing them within the strip.

In accordance with my invention, the tab is permanently secured to the strip preferably when the strip is manufactured, and the binder merely has to place the strip with attached tab on the margin of the calendar or other article and bend the same in the usual manner in the hand brake. Not only does thi method insure the presence and proper placing of the tab but it very materially saves time and labor in the binding operamen.

The combined strip and tab has a further advantage in that it may be more conveniently handled by the binder. Binding strips are generally produced in automatic machines which cause them to become nested or they are so nested by the manufacturer for convenience and safety in packing and shipment. Heretofore, considerable time has been expended by the binder in separating these strips a they tend to hold together rather tightly. When the individual strips are provided with tabs in accordance with the present invention, these tabs may be readily grasped and the strips quiekl-y'and easily separated in their-order of nestingi These and other objects, general and particular, will be best understood byreference to the accompanying drawing, in which?" Fig. 1 is a detail perspective vi'ew of one of the formed elements preparatory toassernbly; I L 1 Fig. "2 i's a detail perspective view of 'another of the elements;

Fig. 3 is a perspective view'ofa'c'omplete binding strip; I 5

Figs-ate? inclusive illustrate thebinding operation, and f Fig. 8 shows the relative position "of the strips when nested for-shipment. Referring to the drawing, a strip of sheet metal is bent into substantially. l-formor trough as shown in Fig. 1, generally with a narrow fold as 1 and a wide fold-as 2, the widths of-the folds depending'on the size of the'calendar or other article to be mounted. A metallic taba's 3, shown in detail in Fig' 2, 'is inserted into the bend of the strip substantially in the; position shown in Fig. 3 and attached to a side-of the strip by piercing the metal strip and tab preferably simultaneously and upsetting the burr thus formed as at 4 or by welding, riveting, cementing or otherwise. only one tab is to be used, this generally would be placed at the longitudinal center of the strip. It will be evident that the attaching of the tab to the-strip may take place before or after the bending of the strip, as preferred. The strip thus formed is read-y to be used in the binding operation. Referring to Fig. 8, it will be seenthat when the strips are nested, the tabs 3 extend one beyond the other with the tab of the first strip outermost, so that these strips may be removed successively by the binder by'grasping such outermost tab Furthermore the tabs prevent the strips from nesting tightly and thus separation is facilitated. I

The binding operation is illustrated in Figs. 4 to'7. The strip with attached tab is placed by the binder in the hand brake or other device for the purpose in the 'usual Where m manner, and one edge 5 of a calendar 6 or other article to be bound is inserted into the bend of the strip in substantially the manner indicated in Figs. 4 and 7. The operation of the hand brake at this time serves to again fold the strip and withit the marginal portion of *the 'calenda'r ga s 'qillustrated in Figs. 5 and 6. The pressure then exerted tightly secures the strip upon the calendar?" It will be evident nemthe foregoing description that the method forming' i-ii part-*- the subject matter of the present invention saves time and labor and"insu'r'es"properbinding. The strips with attached tabsmay be manufactured economically and they very materiallyifacilitatp the? binding opera tion: 2 1 i'ich' Asim-any, ossible embodiments may be made of the Features of the abovc.-invention and as the art,hereindescribed may; ;be'. varied considerably, all without ;-.departing mm sc peof he inven i n, :i o b understood that all matter herein set; forth or 1 shown in the accompanying drawing is to be interpreted as illustrative and not' in-ra.
