Title: Improvements in or relating to machines adapted for operating upon prewelted shoe uppers
IPC: A43D25/18
Filed: 1945-09-21
Abstract: <PICT:0599643/III/1> <PICT:0599643/III/2> The welt of pre-welted shoe upper, particularly for children's shoes, is, while the upper is off the last, simultaneously flattened, a coating of adhesive is applied to its sole-attaching face, and the upper is moulded to a condition in which it will cling to the last with the welt in suitable position for a lasting operation.  As shown in Fig. 3, the welt 12 of a pre-welted upper W is presented between a work supporting and feeding roll 22 of inverted frusto-conical shape driven by bevel gear 24, and a cement-applying roll 14, mounted on a driven shaft 16 in the machine frame, by depressing a pivoted arm 28, which carries the roll 22, by a treadle-controlled cable 26.  The base of the roll 22 supports the welt against the roll 14 and the wedge shaped periphery serves to separate the welt and upper.  A guard is placed in front of the roll 22.  The rounded end 32 of a moulding finger 30 carried on a slide 40 may be moved against tension of a spring 72 by a crank 60 mounted on a rockshaft 68, to facilitate introduction or removal of the work.  This movement is effected by a treadle, which may be the one to which the cable 26 mentioned above is attached, and which is connected with lost motion by a chain 84 to lever 82 on a shaft 78 which carries a slotted arm 76, in such manner that the finger 30 is moved out of engagement with the work before the rolls 14, 22 are separated, and conversely to engage the work before the feed movement of rolls 14, 22 commences.  The finger 30 engages the lining or upper of the shoe to hold it against the edge of the roll 22, in which position it is locked against lateral deviation while the welt and upper are being separated by the wedge periphery of the roll 22.  The coating roll 14 may comprise terminal members 110, 124, Fig. 6, on the hub 112 of which is carried a number of annular body portions 118, the whole being assembled on the reduced end 136 of a shaft 138 and held against a shoulder 140 by a screw 142.  A radially-extending pin 144 is brought into engagement with a keyway 146 in the hub of the member 110 to prevent rotation of the portions 118 on the shaft. The portions 118 may be secured by engagement of a key 126 in alternative keyways on their inner peripheries with teeth on their outer peripheries all in register or alternately staggered to form either cement holding grooves or pockets, thus enabling the quantity of cement applied thereby to be varied.

Abstract: 1,151,766. Mixing apparatus. COLGATEPALMOUVE CO. 2 June, 1966 [24 June, 1965], No. 24663/66. Heading B1C. [Also in Division G3] Two components of a detergent composition, at least one of which is a difficultly flowable high solids premix slurry, are mixed in apparatus comprising systems for metering continuous flow of the components in substantially constant proportions, a high shear mixer and a drier. In the Fig. the premix slurry system comprises a hopper 22 continuous flow from which is controlled by a servo 86 in response to a monitoring flow rate signal derived from a strain gauge 79 responsive to the hopper weight. Periodically, hopper 22 is refilled from a hopper 21, the monitoring signal then being derived from a strain gauge 55 responsive to the weight of both hoppers. The system for additives forming the other component is similar, and a comparator 212 controls one or other servo 86, 186, to maintain a constant component ratio. The slurry is fed by a screw 210 to the additive delivery duct 204 and the combined components pass through duct 220, where gas under pressure is added from line 224, to the high shear mixer 222 comprising stator blades 238 and closely meshing rotor blades 236, material passing axially past the rotor perimeter to the exit 242 whence it passes through a rotary kiln, tumbling drum or other drier 256. A component which should be added to the mix as late as possible may be fed through line 228. The servo 86 may control screw 210 instead of a flow valve 86. The Specification gives a minimum value of the "shear factor" of the mixer, defined in terms of mixer dimensions, r.p.m., and mix feed rate.
