Application May 25, 1944, Serial No. 537,246 (01. 1-3) 6 Claims. 1 2 that will appear clearly from the following de This invention relates to a sheet attaching mechanism, applicable more particularly to sta pling machines of conventional form embodying a relatively movable anvil and head for securing a staple through a plurality of sheets, and it has for its purpose to provide a construction that will enable attaching two or more sheets together by scription when read in conjunction with the ac companying drawing, the novel features being pointed out in the claims following the speci?ca tion. ' In the drawing: Fig; 1 is a view in side elevation showing the application of a preferred embodiment of the fastening a staple around one corner of the sheets and extending from around one edge across the , invention to a stapling machine of known form; Fig. 2 is a plan view of the base of the machine, corner of the outer sheet, around the adjacent 10 partially broken away; edge, and back on the opposite outer surface, thus holding the sheets together by frictional en Fig. 3 is a bottom plan view of the stapling gagement between the sheets and the staple, machine head with the plunger in section, show which occupiesonly the extreme corner portion ing a modi?ed form of the invention; Fig. 4 is a side elevation of the construction of the sheets. The usual practice in stapling a multiplicity of paper or other sheets together is to attach the staple parallel to and spaced from one edge, and where the staple is attached at one corner, it penetrates the sheets and is frequently located a substantial distance from the edges so that if it later becomes necessary to separate the sheets, the staple must ?rst be removed by bending back its ends with a suitable instrument, or else the is illustrated in Fig. 3; ’ Fig. 5 is a plan view of a stapling machine base, showing a further modi?cation; Fig. 6 is a plan view showing the application of " a staple to a series of sheets; Fig. 7 is a similar view showing the staple ap plied in a somewhat different manner, penetrat ing slightly the edges of the sheets, and Fig. 8 is a similar view showing the application sheets must be defaced by tearing them apart, 25 of the invention in fastening a sheet to the sur and one object of the invention is to afford a structure that enables fastening together a multi plicity of sheets by means of a staple located at the extreme corner of the sheets so that the staple can be easily and quickly removed with the ?n gers by exerting the tension required to overcome the frictional engagement between the staple and the adjacent surfaces of the sheets, a sheet can be torn off along the line of the staple by de stroying only a small corner portion of the sheet, or a sheet can be pulled out from the rest with out destroying or seriously defacing it. The invention makes it possible to use staples as temporary or frictional retaining devices for holding together a multiplicity of sheets and thus to take the place of the conventional paper clips or other similar fastening elements and effect a considerable saving in cost, while affording ine strumentalities which hold a multiplicity of sheets together with sufficient tightness to function sat face of a larger sheet. The invention is useful and of particular ad vantage wherever it is desirable to attach to gether two or more sheets of paper or other ma terial and hold them in any attached relation as long as desired, while permitting quick'removal of the fastening means if necessary or the re moval of a sheet by tearing it at the corner along the staple where attached, or by removing it against the frictional resistance of the staple. and instances of such uses are found in attaching a check, price list, folder, return card, or other sheet to a remittance blank, statement, letter, or advertising vbroadside respectively, also the fas; tening of a smaller sheet on to a larger sheet in spaced relation to its edges as in affixing mer chandise on display boards, and while the inven tion is susceptible of use with conventional sta ples of standard size, it is preferable to employ isfactorily as a permanent fastener, but permit ting easy removal of the fastener or separation of a somewhat longer staple, for instance about three-quarters of an inch or more in length, so' one or more sheets when desirable. _ Another purpose of the invention is to afford that when the staple is fastened across the cor mechanism. gage a considerable portion of the surfaces of ner portions of a plurality of sheets and extends a structure that can readily be applied ‘to a con- 0 around the adjacent edges in frictional engage ment with the exposed surfaces of the outer ventional stapling machine without requiring re design of the stapling feeding and operating sheets, the fastener is of su?icient length to en ' _To these and other ends, the invention consists; _ the sheets and thus hold the sheets together fric in the construction and arrangement of parts 55 tionally with such pressure as to ‘prevent their 2,405,420 3 4 accidental separation or displacement and to af ford a practically permanent attachment. The invention in one preferred embodiment, a small corner portion of the sheet and does not interfere with any of the usual reading matter, and‘ does not materially deface the sheet. In some cases, if preferred, a single sheet can be removed by holding the sheets and staple in one hand while pulling the sheet to be removed away from the remaining sheets, which are still held as illustrated in Figs. 1 and 2, is shown as applied to a conventional type of stapling machine in cluding a base I, anvil 2 having the usual staple recess 3, while 4 designates the pivotally mounted by the frictional engagement of the staple. head provided with a plunger 5 that is operable In case it is desirable to provide for fastening to force a staple through the staple channel 6 10 sheets either win the manner described, or in the into the staple- recess 3 of the anvil. conventional way by penetrating the sheets, the In order to position the sheets ion the anvil positioning means can be arranged to be re in the required relationship to the staple recess tractable out of operative position, if desired to and staple, so that the latter will extend across fasten a staple in the conventional way.

While the sheets are held in position with ad In. ollleration, the larger sheet is arranged in any vdesired position over the anvil on the base while the smaller sheet is held by the operator against the guides VI‘! of the movable ‘head as the plunger is forced downwardly. This will cause the sheet immediately under the movable head to assume the proper relation to the staple and staple recess so that when fastened to the larger .sheet, the stapleextends around the edges of the smaller sheet and across the corner ,por tion thereof, permitting the latter to be removed readily from the larger sheet if desired. This result ,can also be accomplished by fastening across the corner portions of the sheets and he guides l'l ?xedly to the movable head in such around adjacent edges, as illustrated in Fig. 6, or as in Fig. ‘7 where the edges are penetrated 65 position that they do not interfere with the downward movement of the head on to .the anvil. slightly by the staple.
