Unire sra'rs LOADING DEVICE FR "W'RFl-STAPLING"MACHINES.

Application filed February 9, 1925. Serial No. 7,815.

VThis invention relates to feeding devices .tor wire staple machines, and has for an object to provide a device for facilitating the loading' of the wire staples in the machine to prevent loss of time and trouble, and also to prevent loss of the staples during` the loading` operation.

l.Vith the foregoing and other objects in view, have devised the construction illustrated in the accompanying` drawing forming a part of this speciilieation, similar reierence characters being employed throu out the various figures to indicate corresponding elements. ln this drawing,

F ig. 1 is a side elevation of a stapling machine showing the method oi using my improved loading,l device.

Fig. 2 is a top plan view of the rear end thereof. y

F ig. 3 is a top plan viewof the-loadingdevice.

Fig. tis a longitudinal section thereof substantially on line 4 4 of Fig 3.

Fig. 5 is a transverse. section substantially on `line o Fig. 3.

Fig. 6 is a longitudinal section through a loading device of a slightly different construction, the section being); taken substantially on line 6 6 of Fig. 7.

Fig'. 'Z' is a rear end view of the device shown in Fig. 6, and

l? 8 is a top plan and side elevation of the retaining` clip on an enlarged scale.

l have shown merely in outline a staplingg machine ter use in setting` substantially U- shaped wire staples, the machine comprising a base 10, and a housing 11, pivoted to the base at and containing' the mechanism for feeding; and setting the staples. This mechanism is not shown as it forms no part of my present invention, but it is operated by the usual plunger 13 which is reciprocated by the hand lin-ob 14 and spring l5 in 'the well known manner. In this type of machine there is a staple support or `fluide, usually comprising a substantially rectangular bar 16, which projects through the rear end oit the machine and on which the staples are placed for supplyingl the 'feeding` and setting mechanism. The staples are fed to the machine by placing them on the rear end of this support or guide and then slidinfr them along this guide into the machine.

For .t'acilitating` this operation both to save time and trouble and to prevent loss ot staples during this i'eeding` operation I have devised the feeding devices shown in Figs. 3 S. ln the construction shown in Figs. 3 to 5 the device comprises asupport 1i" of sheet metal bent to substantially Ushape in cross section and of a length to support the desired number' ot' Ll-shaped staples 18 placed side by side so that they embrace the sides and top of the support as shown. lieretofore it has been diicult to prevent these staples 'from dropping ofi the support while 'feeding them to the machine. ln th present construction l overcome this di leu u.. The top 19 of the support is slit longitudinally by two spaced cuts 20 and the metal 21 between these two cuts is forced .ipwardly above the plane of the top 19 a sufficient distance to allow the staples to pass between it and the top, but it is sutlieiently close to the top to prevent their dropping oit. One end of this retaining member is left attached to the top as shoiwn at 22 while the other end 23 isi-'ree so 'that the staples can pass oil or on under this 'tree end. To strengthen this strip or retaining member it is provided with a longitudinally extending' ribQ pressed into the strip and preferably extending downwardly so as to provide a groove 25 in the top of the strip, altho of course it may extend upwardly if desired. rEllis groove, however, is stopped short oit the 'free end Q8 for a purpose presently to be described. As the 'formation oi this retaining` member 21 weakens the top portion. of the support the metal of this top portion is strengthened adjacent the oppesite ends thereof by transverse ribs 9.6, but th se ribs do not entend the entire width ot' the top because in that case the staple would fall into them as they pass oli' this support.

Asindicated in Figs. 3 and d the staples 18 are placed on the support side by side embracing the top and sides ot the support, but they lie under the retaining member 21 which holds them aggai. st the top of the sup-- port. To retain thesestaples on the support and prevent their passing oit under the free end of the retaining member 2l during; handling and transportation means is provided for holding' them on the support, which in the present instance, comprises a metal clip 27 bent upon itself so that it embraces the
