(01. 1-3) w This invention relates to a stapling machine the casing the longitudinal ribs (1 are folded over and has for its object, to produce an article which to form end flaps e, which lie in the same plane as is simple to make and reliable in use'.- The main. the also folded over extensions f of the side walls feature of, the invention is the sheet metal casing b. On the rear end of the inwardly bent shoulders 5 bent into substantially U-shaped from a single short extenssions g are provided, which cover piece accommodating the staple carrying device, the longitudinal slot 71. betwen the shoulders c.

Fig. 4 is a side elevation of the finished casing. knob 10.
Figs. 5, 6, and '1 illustrate the casing, shown in As shown in the drawing the spiral spring 11 side elevation in Fig. 4, in top plan view, rear ele is of conical shape and can be pressed, flat. The vation and front elevation, respectively. arrangement of the spring around the shank 33 40 Fig. 8 isaside elevation of astapling machine in is such that the wide coil engages in the cup- 95 the shape of a pair of tongs with casing formed shaped striker knob, whereas the narrow coil according to the invention. bears against the casing. 0n the knob 10 being The casing 1 (seen from all sides in Figs. 4 to struck, the spring 11 is pressed flat and lies in 'l) of the desk stapling machine (Fig. 1) consists the cavity of the knob 10. The guide rod or of a single piece of sheet metal, the original develshank 33 can therefore be shortened bythe 1% oped shape of which is shown in Fig. 3. By suitamount to which the cylindrical spiral spring, ably bending at the points indicated in dotted usually employed at this point, could be comlines, a channel-like elongated body is formed pressed. By making the striker knob 10 of cupwith lateral downwardly bent end flaps overlapshape with slightly inwardly bent edge, which ping the same, the bottom portion of this body is simply stamped or pressed in sheet metal or 105 being designated-by a and the side walls by Z). other suitable material, a special bearing for the The side walls b are bent inwards on the upper spring is not required on the knob. side forming shoulders c and continue thence as A nose 13 hinged to the guide plate "I by means upper longitudinal ribs d, which impart the necof a bolt l2'holds back the staple actually brought essary rigidity to the casing: On thefront end of under the ram 8 from the staple ranging device 1 operation of this nose does not form a feature of the present invention and is described more fully in my Patent 1,740,322. .The staple support bar 2 is hingedly connected at its rear end byv means of a pin 14 to cheeks 15 of a base plate 16, which forms the counter bearing for the staple ram 8. In the form of construction shown in Fig. 1 a separate'anvil block 17 is provided on the base plate 16 under. the staple ram 8. A blade spring 18 fixed on the base plate 16 bears with its free end against the underside of the casing 1 and holds the ejecting device '7, 8 at a sufilcient distance from the anvil 17, when the machine is in the inoperative position, so that the object to be stapled can be easily inserted.
After a blow has been struck on the knob 10 and caused the staple under the staple ram 8 to be driven out, the knob returns into its in-' operative position, and the passage forintroduc-' ing a fresh staple into the guide slot 9 under the ram 8 thus becomes free. The feedingof the staples is efiected automatically by the arrangement hereinafter described. A rider 19, bent from sheet metal in staple shape, rides on the bar 2 carrying the staples behind the row of staples 3 at the opposite end to the ejecting device. A nose 20 on the web of the rider 19 is bent vertically downwards, so that it extends between the arms of the bar 2. {1 guide rod 21, on which the rider 19 is movably mounted by means of a bore 22 of the nose 20, liesbetween the armsof the bar 2 and is thicknened at its end 23 so as to prevent sliding off of the rider 19. 1he other end of the guide rod 21 is bent to form a how 24 which engages around the covering of the staple guide formed by the extensions 9 of the casing 1, so that it is prevented from shifting. A spiral spring 25 is wound around the rod 21 between the nose 22 of the rider 19 and the how 24. This spring 25 at one end presses the rider' 19 against the row of staples 3 and at the other end holds the bow 24 tightly against the extensions 9.
For inserting a fresh row of staples, the how 24 of the rod 21 is raised and can then be pulled out towards the rear. As the thickened end 23 of the rod 21 prevents the rider 19 from sliding 011, this rider is removed from the machine with the rod, and the insertion of a new row of staples can be easily effected in a simple manner by sliding them onto the bar 2.
By making the casing in one piece of bent sheet metal, thus uniting a number of elements necessary for the construction and reliable working of the machine, the machine can be made very simple, its operation is particularly easy and its cost of production is considerably less than that of the known forms of construction.
Although the description is limited to the form of construction shown in Figs. 1 to l, the construction of the machine can be changed without departing from the scope of the invention. Thus, for example, the guide and support bar 2 shown pin to be inserted into the slot 26.
or guide bar 2. The construction and manner of in Figs. 1 and 2 worked from a piece of square iron can be bent U-shaped from sheet metal, and the base plate-16 may be stamped in sheet metal and suitably formed. Moreover, the invention is not limited to desk stapling machines but can be employed for all kinds of practical stapling machines.
Fig. 8 shows in side elevation a stapling machine in the shape of tongs provided with a staple guide fiormed according to the invention, which tongs are actuated in known manner by pressing together the two jaws 29 and 30.
The casing 1, of the staple guide corresponds to the casing 1 of the desk machine (Fig. 1). However, for the extensions g arranged on the casing 1, which extensions formthe holding means for the staple feeding device, an angular slot 26 on the rear end of the elongated body is substituted, in which the bow of the guide bar engages. Instead of the bow, a knurled head 27 is preferably placed on the rod-21 in this form of construction, and carries a laterally projecting The unfastening of the feeding device is effected in this form of construction by turning the knob 27. The two jaws 29 and 30 of the tongs, which approach each other when operating the device, are mounted in eyes 32 of the reinforcing ribs d of the casing 1' by means of a bolt 31.
I claim:
