899,727. Reservoir pens combined with stapling machines. OFREX Ltd. Sept. 23, 1960 [June 24, 1959], No. 21699/59. Class 146(3) [Also in Group VII] A retractable ball-point pen has a stapling mechanism enclosed and gripped by a removable cap mounted at the rear end of the pen in such a way that retraction of the writing point may be controlled by movement of the stapling mechanism. The ball-point writing unit 3 is slidable in a barrel 1 and is threaded in a member 5 having an inclined rear face 6. The member 5 is slidable but not rotatable in the barrel and is biased rearwards by a spring 9. A member 11<SP>1</SP> is mounted rotatably but axially immovably in the rear end of the barrel and has at its front end two inclined faces 12, 13 against one or the other of which the member 5 is urged by the spring 9. The writing unit extends through and is slidable in a bore in the member 11<SP>1</SP>, rotation of which effects projection and retraction of the writing unit, the projected position, wherein the face 13 abuts against the face 6, being shown in Fig 1 and the retracted position, wherein the faces 12, 6 abut, being shown in Fig. 2. A magazine 16 for staples 20 is releasably secured to the rear end of the member 11 by resiliently mounted projections 34 on the magazine which engage depressions on rearward extensions 31 of the member 11<SP>1</SP>. The writing unit 3 extends into the magazine 16 and has a feeder 21 for the staples slidably mounted thereon and biased rearwards by a spring 22. Leaf springs 17, 18 are mounted outside the magazine 16 and carry respectively a driving blade 17a for the staples and an anvil 19, a tongue 44 cut out of the magazine engaging a slot 43 cut in the blade 17a to guide the latter. A workpiece to be stapled is put between the magazine 16 and the anvil 19 and the leaf springs 17, 18 are then pressed together so that the blade 17a slides down a groove 32 in the magazine and drives a staple 20 into the workpiece. The magazine is refilled with staples by detaching the magazine from the member 11. The feeder 21 is retained on the writing unit by the belled end 36 of the latter. The writing unit may be exchanged, when the magazine has been removed, by unscrewing it from the member 5, the spring 22 and feeder 21 being either renewed with the writing unit or slid off the front end thereof and placed upon the new unit. A cap 41 is a push fit over the part 11 and when in position holds the springs 17, 18 in close contact with the magazine 16. The writing unit may be projected and retracted by rotation of the cap or, when this is removed, by rotation of the stapling mechanism.
