Abstract: 560,347. Coating machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., RICKS F., and BAGSHAW, C. M. Aug. 22, 1942, Nos. 11835/42, 1340/43 and 12370/43. [Class 95] A machine, organised to apply coating material to a shoe heel-end moulded stiffener, comprises coating material applying means, stiffener-supporting means, and means for causing relative movement to take place between said supporting means and said applying means to cause coating material to be applied to side and rear portions of the stiffener while it is held in place with respect to said supporting means. The machine illustrated allows paste to be applied to a shoe heel-end stiffener in such a manner that the upper margin of the stiffener remains unpasted. Stiffener clamping and supporting devices are rotatably carried on a reciprocable cross-head 5. They comprise a V-shaped member 11, 13, having a peripheral recess 15 to receive the flange of the stiffener, a V-shaped clamping block 53, and spring- activated clamping plates 63 which engage the upper margin of the stiffener, thus protecting this portion from being pasted. The block 53 may be provided with a spring-pressed end piece 227, to facilitate removal of the pasted stiffener. Internal and external driven pasteapplying brushes 81, 83 are carried on shafts 85, 91, and the shaft 85 can pass within the V-shaped member 11 when the work is moved towards the applying brushes. Paste is supplied to the brush 83, in regulated amounts, from a container 103, and the brush 81 receives paste from the brush 83. Driving means include chains 21, 47, pulley blocks 17, 43, and a driving sprocket 135, and the direction of drive may be reversed by means of open and crossed belts 151, 153, shifted by a bell-crank lever 161 operated by a rod 169 and knob 171. Blocks 179, 185 on pivoted levers 177, 183, are adapted to co-operate with notches 191, 189 on a bar 193. As the cross-head 5 is reciprocated, rising and falling movements are given to the brush 83 and to the container 103 by means of the cam-piece 197 and cam rolls 195 and 213. A shoe heel-end stiffener S is presented to its supporting and clamping means with its extreme heel-end extending towards the front of the machine, and the rod 169 is pulled forwardly. As the cross-head 5 moves rearwardly, the clamping plates 63 and the block 53 hold the stiffener. On further movement towards the brushes 81, 83, the lower edge portion of the upper side of the stiffener, both inside and outside, remains free from paste, while the remainder of the upper side is coated externally and internally. When the notch 189 on the bar 193 rides into engagement with the end of the lever 183, movement of the cross-head is arrested, and the member 11 and the stiffener supporting and clamping devices are rotated until a stop screw 27 on the disc member 23 disengages the lever 183 from the notch 189. Continued pull by the chains 21 and 47 causes continued rearward movement of the cross-head 5, so that the remaining portions of the stiffener, other than the edge portion, are coated. Continued rearward movement of the cross-head causes reversal of the drive, and the cross-head returns to its initial position, the coated stiffener is freed, and the machine is stopped. Specifications 548,971 and 558,560, [both in Group VII], are referred to.
