Abstract: 8720. Rydquist, A. June 12. Sale apparatus; delivery mechanism.-Articles stored in a vertical pile 8, Fig. 1, are delivered into a shoot 4 by a drum 22 rotated through a quarter of a revolution at each operation by a spring-controlled pawl 37, Fig. 3, pivoted to a rack-bar 29 and engaging pins 27 on the drum ; a recess 34 is formed in the rack-bar directly above the pawl 37 to permit the movement of the pin 27 driven by the pawl. The rack-bar is operated by a pinion 43 on a sleeve 44 rotated from an external handle 50. Coin action, mechanicalconnexion; testing and diverting coins.-A coin-carrier 53 attached to the sleeve 44 is provided with a recess 58, Fig. 8, for the coin, and in an extension of the recess works a coin-discharging slide 59 having a projection engaging a groove 60 in the base of the recess ; a covering-plate 54 is secured to the carrier. Spring- controlled plungers 80, 81, Fig. 10, working in chambers in a casing 78 extending rearwardly from the carrier 53, project through slots in the plate 54 into engagement with a fixed frame 47 ; a part of this frame is directed forwardly, so that the extremity 88 of the adjacent part 90 acts as an abutment. The carrier is rotated by a member 68 connected to the handle 50 by a pin 70, a projection, 67 on the member engaging an abutment 77 on the plate 54. One edge of the inserted coin rests against the bevelled side 64 of the recess 58, and the other edge is engaged by the plunger 81 ; if the coin is of correct diameter, the plunger 81 is held up with its bevelled portion 93 above the edge of the coin, so that as the carrier rotates, the extremity 92 of the plunger passes over the abutment 88 on to the part 90 of the frame 47 ; similarly, if the coin is of correct thickness, an arm 85 bearing on the centre of the coin and connected to the second plunger 80 maintains this plunger above the abutment. If, however, the coin is of insufficient diameter or thickness, the corresponding plunger or both plungers engage the abutment 88 and lock the carrier against further movement. To prevent operation of the apparatus by a coin or disk which is not perfectly circular, a pivoted spring-controlled detent 98, Fig. 7, is employed, having a shoulder 107 extending into the path of a pin 106 on the carrier ; after the plungers have passed the abutment 88, the coin engages a retaining-shield 108, and, if the diameter at rightangles to that previously tested is correct, the extremity of the slide 59 projects from the carrier into the path of a projection 104 of an arm 103 on the detent 98 and rocks the detent, thereby removing the shoulder 107 from the path of the pin 106 and permitting the complete rotation of the carrier. The coin is discharged from the carrier by the slide 59, the movement of which is effected by the engagement of a pin 66 on an arm 65 projecting from the slide with a fixed abutment (not shown). An unsuitable coin is discharged from the carrier by turning a handle 50 in the reverse direction, the projection 67 engaging the pin 66 and moving the slide 59. A spring 76 returns the slide 59 to the normal.position.
