IPC: G07F11/02
Abstract: 109,976. Gralla, J. Sept. 26, 1917. Coin action, thrust and multiple-coin. - Goods - delivery mechanism of various types and prepaym e n t attachments for gas and electricity meters may be operated from a push-piece 1, within which are pivoted one or more detent levers 4 adapted to be positioned, to permit the inward movement of the push-piece, by inserting one or more coins 13; return movement of the push-piece is prevented by a lever 21, until this lever has been set by the coin or coins 13 after their discharge from the push-piece. The pivoted lever 4, Fig. 2, is raised by the insertion of the coin 13 so that its arm 4<1> is brought opposite an aperture 7 in a fixed partition 5; during the inward movement of the push-piece, the coin falls through an aperture 20 in the support 14 on to the lever 21, tilting that lever into the position shown in full lines so that its arm 23 is clear of a projection 28 on a spring arm 26 secured to an extension 3 of the push-piece. Fig. 5 shows a modified apparatus prov'ded with two detent levers 4<a>, 4b, rendering necessary the insertion of two coins 13, 13<1>, the coin 13<1> resting on a spring. controlled support 31, which is moved laterally by a bevelled projection on the pushpiece. Alternatively the detent lever may be disposed so as to be operated by the face of the coin. Exhibiting coins.-The coin 13, Fig. 2, is supported by the lever 21 behind a window 17 and is discharged at the next operation of the pushpiece by the engagement of a projection 27 on the spring arm 26 with a projection 24 on the lever. Fraud, preventing; testing coins. - An electric alarm may be employed to indicate an attempt to operate the apparatus without first inserting a coin. For this purpose the partition 5, Fig. 2, is pivoted so as to be moved backwardly by the lever 4 and permit a bridge piece 6 to drop and bridge contacts 8, closing the alarm circuit. The lever 21 may be counterweighted so as to be operated only by a coin of correct weight. Delivery of articles stored between coils of helix.-Articles 12, Fig. 2, are stored between the coils of a helix 11, which is geared to a disk 19 provided with projections 9 adapted to be operated by the extension 3 of the push-piece. Alternatively, the helix may be rotated by the return movement of the push-piece. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter: Delivery of stamps from strips.-A feed-drum 35, Fig. 7 (cancelled), is rigidly secured to the disk 19 and the strip 34 is pressed against the drum by a rolier 37. A spring-controlled cutting- blade 39 works within the drum and normally projects through one of a number of apertures 36 spaced to correspond with the lines of separation between the stamps. A pivoted pawl 43 carried by the extension 3 of the push-piece draws back the blade 39; at the conclusion of the inward movement, the pawl is tripped by a fixed incline 44 permitting the spring 41 to return the blade, which severs the foremost stamp. Delivery of articles stored in bulk.-A disk such as 19 is secured to a cylinder provided with scooplike projections serving to deliver cylindrical articles from a storage hopper. Delivery of articles stored in piles. - The de. livery slide for pushing out the lowest article of a vertical pile is secured to the push-piece, together with a cut-off for preventing delivery until the push-piece has returned. In the arrangement shown in Fig. 12 (cancelled), the push-piece normally servos to rotate a series of goods-containers 56, which are disposed around an axle 55, in front of a viewing window 57, an arm 60 of the lever 4 engaging a wheel 58 on the axle. If, however, a coin 13 is present, the arm 60 is held clear of the wheel 58, and operation of the pushpiece effects the delivery of an article from the selected container through any suitable mechanism. This subject-matter does not appear in the Specification as accepted.
