Abstract: 193,527. Wade, H., (Automatic Recording Safe Co.). Nov. 30, 1921. Machines for making and covering boxes.-A machine for assembling and covering the parts of a book-form safe, Fig. 29, comprises a press having a bed B, Figs. 1 and 2, provided with a deep transverse socket D and a shallow socket E leading therefrom. Mounted on the bed in front of the socket E are angular folding-plates F, F<1> slidable on oblique guides 28 and advanced towards the socket bv a hand-actuated slide F<2> connected by links 35, 37 with the slides which are held in the retracted position by springs 30; the joints between the levers 35, 37 carry rollers engaging guides or cams 40 and slidable cornerfolding members G, G<1> are arranged below the cams and plates F, F<1>. The socket D is adapted to receive the holder or die D<1>, Fig. 23, described in Specification 192,239 and having secured therein, by slidable clamping-members 19 in the ends thereof, the main body portion 1 and the leather or other covering 5 of the safe, the holder having end blocks 21 carrying studs 22 which enter holes 10 in the bottom of the socket and position the holder therein with the member 1 and covering 5 lying over the socket E; a felt or other pad 6 may be introduced between the parts 1 and 5. A plunger C carried by a stem C' having a rack engaging a pinion C' on a hand-operated shaft C<3> is mounted in guides 11<5> above the socket E and is operated to force the member 1 and the covering 5 into the socket, the plunger being then locked in its lowest position by a pivoted dog 11. Slides 23 mounted at the ends of the socket. 10 are then forced inwards to clamp the margins of the covering over the margins of the member 1 after which, the plates F, F<1> are advanced to fold the cover over the edges of the part 1, perforations 5b in the cover engaging over clinching lugs 1<b> struck up therefrom. The members G, G<1> are then forced inwards to iron the cover corner tabs 5<a> over the corners of the part 1, springs 43 holding the members G, G<1> down and returning them to the retracted position. The flanged U-shaped member 2, Fig. 25, forming the edges of the safe is then positioned on the member 1 by perforations 2b in the flange 2<a> engaging the lugs 1<b> and a sleeve C<5> surrounding the stem C<1> carrying dies 8 is lowered to clinch the lugs 1<b> over the flange 2a; the sleeve carries rollers 9 and is actuated by cams C<8> engaging the rollers and carried by a handoperated shaft C<7> journaled in the stem. The sleeve and plunger C are then raised and the holder D<1> with the assembled parts removed from the socket D, turned end for end and through 90‹ and reinserted-in the socket in the position shown in Fig. 26, grooves 24 in the holder allowing it to slide below lugs 23a on the retracted slides 23 while the inner edges of the blocks 21 engage the ends 47a of the upstanding rear wall 47 of the socket. The cover-plate or closure 3, Fig. 27, of the safe is then positioned on the covering 5 over the socket E with a spring 3c secured thereto engaging a catch or projection 1<d> on the part 1 and rear lugs 3b interengaging with lugs 1<c> thereon, the covering being held stretched over the socket E by a removable bar applied at the front of the socket and having studs which enter holes 44b in the bed of the press; a second pad may be introduced between the parts 3, 5. The bar is then removed, the plunger C' is lowered to clamp the closure and covering in the socket E and the folding-plates F, F<1> and corner-folding members G, G<1> are operated to fold the edges of the cover and the corner tabs over the closure 3 with the perforations in the cover engaging the upstanding lugs 3a thereof. The flanged U- shaped rim 4, Fig. 28, of the closure is then applied with the perforations 4b in the flange 4a engaging the lugs 3<a> and the sleeve C<5> operated to clinch the lugs over the rim. The finished safe is then removed from the holder, the closure which is forced outwards by the spring 3c being locked from the key barrel 48 by a member 2c on the edge member 2 engaging a locking member 4c on the rim 4. The member 2 is of satin brass to simulate the gilt-edges of a book and has a coin insertion slot 49.
