Title: Improvements in coin-freed apparatus
Filed: 1926-02-06
Abstract: 275,278. Brecknell, Munro, & Rogers, Ltd., and Dolman, H. J. Feb. 6, 1926. Testing coins.-In coin-freed apparatus the coins are received in an oscillatory carrier 14 pivoted at 22 and counterbalanced by a threaded weight 18, the carrier rocking and delivering the coins, if they are of sufficient weight, have a milled edge, and are of correct diameter, to a shoot 23 leading to the releasing mechanism. Un-milled coins or coins of small diameter drop from the carrier before it reaches the position over the shoot 23 and pass to a return shoot. The carrier is provided with two pawls 19, 20 held in engagement with the milling by the weight, of the coin and by a spring 21 respectively. The coin is released to pass to the shoot 23 by a, tail 20a. on the pawl 20 engaging a stop 24. Underweight coins fail to rock the carrier, and overweight coins tilt a counterbalanced lever 26 and drop through an opening in the shoot 23. Operation of the carrier by two underweight coins inserted in succession is prevented by a rod 28 on the carrier interlocking with the second coin, thus preventing the complete oscillation of the carrier. The carrier 14 may be used alone or in conjunction with known means for rejecting perforated and iron discs, coins of too large diameter, and coins which are either too thin or too thick. These means comprise a, shoot 6 formed from a downwardly inclined member 1 having a member 4 hinged thereto and provided with a ledge 4d on which the coins run on edge. The member 4 is held by a spring 9 against an adjustable stop 12 so as to leave a space between the ledge 4d and the member 1 through which thin coins drop. Perforated discs are stopped by an arm 7 hinged to the side 4 and projecting through a slot 4a into the shoot 6. Iron discs are held up by a magnet 10. Coins of too large diameter are prevented from passing by the size of the insertion slot, by a rib 1a and projection 4c on the sides 1 and 4 respectively, and by a gauging screw. The member 4 is turned on its hinge pin 5 to allow the rejected coins to pass to a return shoot by connecting an arm 4b thereon to a delivery drawer which can be pulled out slightly without delivering an article. Specification 237,416 is referred to.

Abstract: 631,888. Vulcanizing chambers ; moulding sponge rubber. DUNLOP RUBBER CO., Ltd., and DIBDIN, T. J. R. Feb. 11, 1947, No. 3927. [Classes 70 and 87 (ii)] Apparatus for vulcanizing compounded aqueous dispersions, particularly foamed dispersions, of natural or synthetic rubber in moulds comprises a rotatable base having a plurality of mouldsupporting positions and adapted to locate each position in turn at a predetermined station, a stationary cover member located above said station, means for raising said base into contact with said cover to form a chamber enclosing any of said positions and for lowering said base to open said chamber, and means for introducing steam within the said chamber. In the embodiment described, a base 3 is mounted on a pillar 4 by means of a cylindrical member 5 so as to be both movable vertically relative to the pillar and rotatable. thereon, the base 3 being formed of two parts, one on either side of the cylindrical member 5. Each part comprises a rectangular framework with a number of bars extending across to support a mould, with a trough 8 to catch condensate, this trough being fitted with an S- shape trap 9 from which condensate can escape without permitting the escape of steam, and which prevents the pressure within the chamber from rising above atmospheric. The cover member 2 is supported by a fixed framework 26, 27 and is formed with side walls 29 and roof portion 30, inlets 32 being provided for introducing steam; a sealing strip 31 is provided to contact with the framework of the base 3. The upper part of the pillar 4 fits closely in the member 5 and is provided at its upper end with a sealing device comprising packing 15 held in place by a disc 16, thus enabling the pillar to act as a piston housed in the chamber 21 constituting the interior of member 5 ; the member 5 and hence the base 3 may be raised or lowered by introducing hydraulic fluid to or extracting it from this chamber. When using the apparatus a mould is placed on that half of the base 3 which is not under the cover 2, ungelled latex foam is delivered into the mould and the foam allowed to gel. The base is then lowered and rotated to bring the mould under the cover 2, and hydraulic fluid supplied to the chamber 21 so as to raise the member 5 until the sealing strip 31 is in close contact with the framework of the base 3. Steam is supplied to the chamber formed by cover 2 and trough 8 and vulcanization takes place. While vulcanization is proceeding a second mould is placed on the other side of the base 3 and is filled with dispersion and allowed to gel in the same way. When vulcanization and gelling are complete the base is again rotated, the mould containing vulcanized dispersion is removed and the process repeated.
