Abstract: 10, 110. Tascher, J. E., and Tascher; A. April 30. Wrappers.-Bottle envelope blanks consisting of tubes of corrugated paper 1, Fig. 1, covered with smooth paper 2 are pressed into a conical shape at one end, which is then secured by a binding- ring 24, Fig. 2. Two forms of operating - mecbanism are . described, one a hand-operated apparatus and the other. an automatic apparatus comprising an intermittentlyrotating horizontal carrier which carries the envelopes to the successive operating stations. In the handoperated apparatus, the cylindrical blank to be operated upon is slipped over the spring wires 16, Fig. 3, of the spring-supported holder 15, which, during this operation, is. maintained in its raised position by the rod q bearing upon the table 4. The pivoted lever s, upon which the holder 15 is mounted, is swung inwards to bring the envelope blank beneath the' sbaping-cone e, and the hand-lever 8 is then pressed downwards, thus ,allowing the cone e to .slide down the guides a, b until it is supported by the resistance of the blank and of the enclosed spring 16. The cone e then remains stationary for a short time, the .pins 6, by which it is operated, sliding freely in the slots h in the pieces g secured to the lever 8. The conical ring 13, Figs. 3 and 7, is meanwhile drawn down by the connecting-links 12, and presses together the four spring tongues 20 secured to the cone e. The pedal-lever u is then pressed down, thus lowering the holder 15 within the envelope blank against the action of a spring contained in the casing o, the rod q meanwhife slipping into the slot t in the table 4. The holder 15 is maintained in its lowered position by means of a catch. The shaping-cone e may then be lowered farther by the lever 8 until the shaping operation is completed. A binding-ring 24, Figs. 5 and 8, is then dropped upon the four spring tongues z, from which it is pressed on to the neck of the envelope by the circular hand-operated slide l adapted to be pressed downwards against the action of the spring 27. When the levers 8, 3 have been returned to their original positions, the finished envelope may be removed from the machine. The automatic apparatus, which embodies the principles adopted in the hand-operated apparatus, is shown in Figs. 10; 11, 13, 16, and 19. The envelope holders, which are four in number, are mounted on a table 5, which is periodically turned through a quarter of a revolution by the swinging rod n engaging with four pins o on the plate p. An envelope blank is placed upon each envelope holder when the latter reaches the position a<3>. The table 5 then turns to bring the holder to the position a<4>, the envelope blank, during this movement, lifting the pivoted piece 51, Fig. 10, and thereby operating the binding-ring supplying-mechanism shown in Fig. 19. The upward movement of the rod 53 pivoted to the piece 51 causes the catch 65 to engage with the slide 60, which is then drawn to the left against the pressure of the spring 62, by means of the cam-actuated lever 66. This movement allows one of the binding-rings d to slip through the hole 61 and slide down the rod 56 until it rests upon springs, Fig. 13, secured to the shaping-cone c, below which the envelope holder rests when it reaches the position a<1>. The camoperated rods x, Figs. 10 and 11, then descend, first causing the conical ring w to press inwards the springs u which grip the binding-ring in the notches v, and then causing the shaping-cone c to descend until its progress is resisted by the envelope holder. The envelope holder is then lowered in the envelope blank by the lever 28, Figs. 10 and 11, and is retained in its lowered position-by the spring catch 29.-The. cone c then descends farther and completes the shaping operation, the binding-ring being carried down as shown in Fig: 16. When the shaping-cone has been returned to its original raised position, the holder transfers the finished envelope to the position, a<2>. The plate 39 upon which the envelope rests is then thrown quickly upwards by the lever 38, and the envelope, after passing through the guiding-cone 42, falls into a suitable collector. As the envelope holder returns to the position a<3>, the catch 29 is raleased and the holder returns to its original raised position. Various parts of the machine are adjustable to enable it to be used for envelopes of different sizes.
