Abstract: 1,209,169. Glassware transfer device. EMHART CORP. 20 Nov., 1967 [8 Feb., 1967], No. 52578/67. Heading C1M. A transfer apparatus for use with a glassware forming machine of the type having a plurality of sections arranged alongside a continuously moving take-away conveyer comprises a deadplate 12 associated with each section for receiving newly formed ware, the deadplate having two side-by-side zones G<SP>1</SP>, G<SP>1</SP>; G<SP>11</SP>, G<SP>11</SP> for cooling the newly formed ware, a cam-shaft 14 driven by the machine, a wire engaging bar 16 above the deadplate, a first cam 70 on the camshaft, a first lever 68 located below the deadplate and pivotally supported on the upper end of a rockshaft for movement between first and second positions in response to the movement of a cam follower 72 carried by a second lever at the lower end of the rockshaft said cam follower 72 connected at one end to the first lever 68 and at its other end to biasing means 64 to maintain the cam follower 72 in contact with the cam 70, a slide block 58 mounted on the chain for linear movement along the edge of the deadplate between two sprockets 52, 54 for the chain, a bar carried by the slide block extending across the deadplate whereby glass ware may be moved from one of two cooling zones G<SP>1</SP>, G<SP>1</SP> to the other cooling zone G<SP>11</SP>, G<SP>11</SP>, and cam-shaft driven means for sweeping the ware from the second zone on to the conveyer in timed relation with the bar movement. The deadplate 12 has at least one perforated fixed plate 12a co-operating with a housing 30 connected to a source of cooling air, e.g. a duct 26 located beneath and also cooling the conveyer 10. Each of the two zones of the deadplate is provided with its own slide valve (34) having opening (36) for individually regulating the cooling air issuing from each zone. When fresh ware has been deposited on the first zone G<SP>1</SP>, G<SP>1</SP> of the deadplate and cooled a predetermined time the timed rotation of cam 70 causes movement of lever 68 which through chain 50 operates bar 18 pushing the ware to the second cooling zone G<SP>11</SP>, G<SP>11</SP> of the deadplate. The bar 18 is returned by spring 64. A pistoncylinder 120-122 (Fig. 5, not shown) then operates to extend linkage means (126), (128) and a ware-engaging pusher element 18 into contact with the ware on the second cooling zone G<SP>11</SP>. The element 18 is attached to a rotatable vertical shaft attached to a sprocket 104. Timed rotation of cam-shaft 14 causes actuation of a cam 108 which in turn moves a lever 110 attached to one end of a chain 118 and which extends around sprocket. 104 the other end of the chain being attached to a spring 116. Thus rotation of sprocket 104 through 90 degrees causes the element 18 to be swung through the same angle thus sweeping the ware from the deadplate on to the conveyer 10, as at G, G<SP>1</SP>. Upon completion of this the element 18 is retracted by piston-cylinder (120), (122) and returned through the 90 degrees for the next cycle. The lever 68 is provided with slip means to prevent its oscillation in the event of ware jamming the deadplate or the mechanism. A flap 20 is attached to the non-machine side of conveyer 10 for movement between horizontal and vertical positions to act as a heat-shield. The apparatus is modifiable for use with conveyers moving in the opposite direction to that shown in the drawings.
