  • This invention relates .tO improvements in printers equipment and the principal object.
  • of the invention is to provide a device by means of which an ordinary brass printers rule may be quickly and easily changed to a brace; this being accomplished by bending or crimping one edge ofthe rule at an intermediate point and at its ends by the action of forming or die members between which theedge of the rule is engaged.
  • I provide a pair of forming or die elements mounted for movement withrespect to each other so as to come together for pressing and forming the rule edge between them.
  • One important feature of invention has to do with a novel and combined arrangement of the provision for bending the edge of the rule ends in conjunction with the means for forming the intermediate bend, whereby the rule can be successively presented in the three positions required for these operations inthe quickest and most convenient manner.
  • FIG. 1 is a side elevation of my lmproved brace former
  • Fig. 2 is a side elevation f the reverse side of the head thereof
  • Fig. 3 1s an end view of the head
  • Fig. 4J shows an edge view of a rule, before and after being formed into a'brace
  • Fig. 5 is a side elevat1on of a modified form of the invention
  • the jaws or die shaping elements 2, 3 hereinafter termed dies are provided centrally of their ends, the one with a lengthwise extending V-shaped projection 4: and the other .with an opposite V-shaped recess '5, the projection 4 shown as being on the die 2 and the recess 5 as in the die 3, the mating faces of said dies at each side of said projection and recess being flat and parallel.
  • the dies 2, '3 are also formed, the-one with a transverse projection 6 and the other with a corresponding recess 8,- the projection 6 being shown as on the die 2 and the recess 8 as in the die 3.
  • the projection has its forward face 7 inclined with reference to the direction of jaw movement and the recess 8 has its front side formed with an inclined face 9 adapted to cooper ate therewith, the inclined formationbeing shown as terminating somewhat short of the extremity of the projection and recess respectively.
  • Figs. 1' to3 I show the die which is formed with the transverse recess 8,11. 6.
  • a modified form of the device is shown, wherein the side slots are eliminated.
  • This rabbeted formation is indicated at 1 1 and the raised portion 13 is shown as extending back so that it forms the top of the inclined forward wall of the transverse recess.
  • Fig. 8 I show a rule 15 being operated on by my improved device to form a central crimp 16 in its edge, the crimps 17, 18 in its ends being formed in the manner already described. From an inspection of this view it will be observed that the three bends or crimps in question can be produced one after the other by a relative shift of the tool and rule continuously in the same direction with a minimum of manipulation, and further that this shifting adjustment is a relative one, 2'. 6., the rule may be conveniently of course one ofthe sides when these are E considered in their'aspect as die elements. In the use of my invention it is possible to complete the making of a brace out of a printers rule without letting go or shifting the grip on eitherpliers, or the rule piece, being treated.
  • a compositor can thus in a moment form a brace of any required length from ordinary -rule stock and be sure of having the brace so formed accurate and perfect. While the device is herein shown as embodied in a plier tool, it is to be understood that this showing is illustrative and not restrictive and that I desire the elements 2, 3 to be considered in their aspect of die shaping members mounted in coactive relation whether on swinging jaws ornot.
  • Apparatus of the kind described comprising a pair of dies mounted for co-active relative opening and closing movement, one
  • said dies being formed with a recess intersecting its body intermediate its ends and extending transversely thereof, the front edge of said recess sloping forwardly to form an inclinedsurface, said die being formed with lateral horizontal extending open-ended recesses communicating with said recess, the back edge of said recess being transverse of said lateral recesses and serving as a stop for metal disposed therein and bridging said first end recess, and a tongue on said other die taking into said transverse recess to shape such metal to the incline of'its front edge.
  • Apparatus of the kind described comprising a pair of dies mounted for co-active relative opening and closing movement, one of said dies being formed with a transverse clined surface, said die being formed with a recess across its face, the front edge of such recess sloping forwardly to form an inlateral horizontally extending open-ended recess communicating with said first named recess, the back edge of said first named recess being transverse of said open-ended re cess and serving as a stopefor metal disposed in said lateral recess and bridging said first named recess, and a tongue on said otherdie taking into said transverse recess to stdiape said metal to the incline of its front e ge.
  • Apparatus of the kind described comprising a pair of dies mounted for co-active relative opening and closing movement, one of said dies being formed with a transverse recess across its face, the front edge of said recess sloping forwardly to form an inclined surface, means at the sides of said die for receiving and guiding metal in strip form to extend across said recess, the back edge of said recess being transverse and serving as a stop for such metal, and a tongue on said other die taking into said transverse five cent recess to shape said metal to the incline of its front edge.
