Definitions

  • This invention has reference to known apparatus used for fastening papers together by cutting out a portion of the papers to a V or similar shape and tucking the said portion through a slit simultaneously cut in said papers. 7
  • An object of my invention is to simplify the general construction of such a device by stamping and bending the main body, including the depressibleportion, from one sheet of metal.
  • a further object is the mode of operating the holding-down plate, a device lying on the table of the mechanism, and employed for holding down the papers during the fastening operation.
  • a still further feature of the said invention is the -i provision of a blotting attachment to the base of the apparatus.
  • Figure 1 is a view of the blank from which the body is formed.
  • Figure 2 is a sectional elevation of the device.
  • Figure 3 is an underneath plan view (with the bottom cover removed).
  • Figure 4 is a similar view showing the positions assumed when the top portion is depressed.
  • Figure 5 is a fragmentary view, to an enlarged scale, of the holding-down mechanism seen in Figure 2;
  • Figure 6 is a similar view in another position.
  • one sheet of metal preferably of springy steel.
  • This sheet has a flat rectangular part a which constitutes the top of the body or base, and has wings which bend into the downwardly extending sides I) and the downwardly extending ends 0.
  • the opposite end, or a portion of same as illustrated, constitutes, when bent into position, a springy depressible member.
  • the portion d is bent and returned and so formed into a curved portion to act as a into a punching head (with or without a bulged disc 2' attached thereto) and carries a slitting cutter 7' of known construction. This may be attached to or stamped out from a blank head it. This is turned down to operate through a suitable slot in the 7 top a.
  • the V or paper-tongue cutter Z may also be stamped and formed out of the head it, or this may be 7 an attached member.
  • the die or reverse m will be stamped out of the table a and a holding-down plate n to grip the papers will be inserted between the tail piece 6 and the table a, and held in position preferably by means of a pin fastened into the table and passing through a hole in the inner end of the plate a so that the latter can move up and down to a limited degree.
  • a bar or plate 0, joining together the two guiding legs 7 underneath the table a, will have an upstanding finger p to pass through a slot 9 in the table a and so lift the plate 12 when the tail piece e, lb, 71 is returned to its normal position by the influence of the spring bend d, which may be reinforced by an additional spring 1'.
  • the plate n is formed with a book .9 into which a spring 25 normally engages when the plate n is depressed.
  • the inclined detent u pushes the spring t clear of the hook s, as shown in Figures 2, 3 and 5, leaving the plate n free to move up! wards, and the raised position is maintained by the finger p as aforesaid.
  • the paper fastening mechanism is of known and common construction and forms no partof the present invention.
  • the members y' and Z and detail structure connected therewith are merely illustrated in position to show a complete apparatus according to the invention.
  • the table a can be constructed as a strip member without the wings b and c, which strip can be riveted or otherwise fastened to a box-like or other base.
  • the box-like base is closed by means of a cover 1) which carries a blotting pad, of chalk, blotting paper or other absorbent material.
  • Paper fastening apparatus constructed from a sheet of metal, having a table, a depressible tail piece bent up in springy nianner from an end of the table and lying substantially parallel thereto, downwardly extending guide lugs to the tailpiece, slots in the table through which the lugs operate, a holding-down plate inserted between tail piece and table and movably attached thereto and paper fastening mechanism carried by the tail piece and co-acting with slots in the table.
  • a paper fasteningapparatus of the class described comprising a sheet metal body constituting a table and provided with slots, an extension at one end of the body adapted to be -folded to overlie the body and having offset flange portions for entering the slots in the table body, and paper fastening mechanism carried by the body and said folded extension.
  • a paper fastening apparatus of the class described comprising a body portion having slots and one end of the body being extended to form a tail piece adapted to be folded backwardly over the body and overlie the same, integral offset flange members carried by the tail piece and engaging in the slots of the body, a spring interposed between the body and said tail piece and paper fastening mechanism carried by the tail piece and the body.
  • a body for paper fastening devices of the class described comprising a table portion and an integral tail portion bent over upon the table and overlying the same,
