This inventionjrel'ates to improvements inhand stapling devices. operating in known manner with staples or clips. In the known hand stapling devices, the device is charged by sliding the clips from the package onto the winged channel, which is to receive the clips. However this cannot be carried out with certainty, so that the clips often have to be applied one by one. If a staple got bent or squeezed or the like, all the clips had to'be removed from the device by drawing or shaking ed the same and the clips again had to be replaced one by one with a considerable loss of time. Further, in order not to unduly increase the entire length of the apparatus, the strokeof the spring for feeding the clips had to be limited, thereby restricting in the appatus the number of clips (about 50 pieces) and this again called for a frequent charging. The invention provides arrangement whereby the charging as well asthe discharging of the clips can be carried out quickly and positively and at the same time the. number of inserted clips is increased,

\ The present invention is illustrated by way of example on the accompanying sheets of drawings, in which Fig. 1 is aside view,

Fig. 9 illustrating the hand stapling device with this bed plate in the extended condition and partly in section.

The arrangement of the main parts of the hand stapling device deviates not essentially but only in operation from the known constructions and consists of the bed plate 1 which is connected by the hinge 2 to the lever piece 3, on the free end ofwhich is guided the top die 4. In the known. constructions out of the groove.

channel member, onto which the clips are fed. According to the invention the clips 5 are charged onto a separate win ed channel member 6, which can be pushed into spaced grooves of the lever piece 3, so that a squeezed or bent staple can be readily removed thereby if the whole winged channel member with the string of cli s is moved backward n the particular construction according to the invention, the channel member 6 1s bent from a sheet metal plate to form a hollow body, which is somewhat resilient and provided with outward bent flanges at the edges of the base, and

- member 6, and the clips can be applied without obstruction and safely onto the member 6.

According to the invention, the pivot 2 is pro- K vided in order to secure the winged channel member in the correct position. For this purpose the flange 9 is cut and bent inward to form an eye 10 (or only to a semi-circular bearing or the like) through which the bolt 2 the lever piece 3 is in the shape of a winged into which the cranked part of the spring is pushed.

slide to pass under the said die. The spring loaded rod 14 is guided in a bearing 15 secured to the slide 11. The bearing 15 is arranged on the slide 11 so far back, that the front face of the slide actually ushes the last clip underneath the die 13. he flanges 12 are formed in such a way, that they allow the head of the spring loaded rod 14 to pass (Figs. 1' and 2) The rear end of the spring loaded rod 14 is in the shape of a handle and at the same time bent down. The member 6 is providedwith two or more holes 16, 17, mo

loaded rod 14 can be placed according to requirement. The eflI'ect is that the whole feed length of the spring can be fully utilized a number of times and therefore more clips can be placed onto the member 6. At first the spring loaded rod 14 is fixed in the hole -'16 if the stapling device is fully charged. If a number of clips have been used, so thatthe spring is slack, the spring loaded rod will be pushed forward thereby placin in tension the spring and its end is place into the hole 17.

A spring 18 is arranged below the hinge and acts on the lever part 3 in such a way, that the same usually is held in the open position and only is turned down by the pressure on the die when using the device.

The construction of the member 6 inthe shape of a hollow'body with eyes 10 allows the hand stapling device, after removing bolt 2, to be used in connection with a special bed plate 19, which according to the invention is shaped like a ruler and preferably graduated and carries an arm 20, which allows the paper to be pinned together to be pushed underneath, so that the sheet can be stitched also in the centre. The graduation ofthe ruler allows a uniform insertion of the sheets.

The arm 20 to be screwed to the ruler is,

punched out of a plate 21 and bent upward. Lugs 22 are formed by bending the free ends, {hi said lugs being provided with eyes for the When using the device, the winged channel member 6 is pushed over the end of the arm 20 and fixed by inserting the bolt 2 into the eyes of lugs 22. The die 23 is fixed at a suitable distance on the ruler.

In the stapling device above described the bed plate, according to the length of the backward extendin staple guide, is little turnable at most at a but 90, so that the band stapling device cannot be used at an object where the bed plate can not pass underneath,

-for instance nailing at boxes or walls and so forth, as the staple mechanism cannot be placed flat on the object-to be treated in view .of the obstruction by the bed plate.

In the construction shown in Figs. 8 and 9 this drawback is avoided in that the rearwardly extending part of the hinged bed plate 13 recessed at least over the width of the staple guide, to allow a turning of the bed plate of substantially-180 with respect to the staple guide, that is tosay that the staple mechanism and the outwardly turned bed plate come to lie substantially in a line.

The bed plate 1 is pivoted to the staple mechanism by means of the hinge. The bed plate 1 is provided with an opening or recess 24, which extends from the hinge to the rear end to allow a swinging of the bed plate 1 with respect to the staple mechanism at 180 into theposition shown in Fig. 9. Now the middle of the box-lid or the like, so that it is possible to fix the lid on the box 26 or strengthening strips to the lid in a most simple manner, without interfering with the bed plate.

To allow for a staple mechanism with long backward extending staple guide 3, the bed plate is also provided with an opening 25 in front of hinge 2, in which the projecting end of the staple guide 3 lies, if the bed plate is tFurned out that is in the position shown in ig. 9. I

In view of the particular arrangement of the bed plate it is possible to apply the hand :stapling device to walls or other large surfaces without removing the bed plate.

I claim 1. A stapling device comprising a lever piece, a pivot pin therefor, a carrying and guiding member for staples bent out of sheet metal and adapted to slide in the lever piece, said carrying and guiding member being adapted to yieldingly slide in tapered grooves and being secured by the pivot pin by means of a lug carried by' said member, the upper portion of the member being provided with spaced openings, and a spring feed device for staples including a guide rod adjustably engageable in the opening of said member corresponding to the condition of the supply of clips.

2. A stapling device as claimed in claim 1, characterized by the provision of a rulerlike graduated bed plate, and a tongue punched and bent out of said bed plate, said tongue permitting the paper which is to'be fastened to be pushed underneath and having on its free end a bearing eye for the pivot pin.
