Title: Improvements in or relating to machines for ornamenting shoes or parts thereof
IPC: A43D93/00
Filed: 1944-07-11
Abstract: 580,777. Ornamenting - machines for shoes. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). July 11, 1944, No. 13208. Addition to 539,896. [Class 17 (i)] A stitch indenting machine comprising a work support and an indenting wheel which is reciprocated in a rectilinear path at an acute angle to the path of movement of the work, as described in the parent Specification, so that it imparts a rapid succession of blows to the work and assists in feeding it, is provided with a wheel carrier which is held towards the work magnetically, and toggle-actuated mechanism, which is unconnected with the wheel carrier, for imparting reciprocatory movements to the latter. The work support is of such weight and is so spring-controlled that it does not yield to the reciprocatory thrust of the wheel but can adjust itself to variations in the thickness of the work. As shown, the wheel 10 is carried rotatably on a pivoted arm 20 which is supported, with the wheel in work-engaging position, by a magnetic stop 28, Fig. 4, carried on a bracket 34 so as to be adjustable heightwise of the work. The upper surface of the arm has a cupped boss 56 engaged loosely by a plunger 46, Fig. 2, the upper end of which is pivoted to the lower of a pair of toggle levers 68, 72 adapted to be actuated by a rod 76 and eccentric 78. The work support 12, Fig. 1, is rotatably mounted on ball bearings in a support 100 adjustable, both angularly and heightwise of the work and carried by a heavy member 126 which is slidably'supported by a spring 132 on a treadle rod 130. The arrangement is such that the wheel is held constantly in contact with the work by the combined effects of the magnet 28, the weight of the arm 20, and a pressure spring 38 engaging the latter, and does not rise in company with the plunger 46. The inertia of the work support prevents lowering of the work under the impulses imparted to it by the wheel, but does not prevent a slow adjustment of its height to compensate for. variations in the thickness of different parts of the work. The work support is rotated by gearing (not shown) driven by a telescopic universally-jointed shaft 176 from skew gears 170 and a main shaft 156 which also drives the eccentric 78 through a belt 88. An adjustable hinged shield 188 is provided for the roll 10 and its associated electric heater 182.

Abstract: 1,189,662. Enlargers for half-tone records. H . HOWSON Ltd. March 23, 1967 [March 24, 1966], No.13581/67. Divided out of 1,189,661. Heading G2A. In an enlarger for making half-tone colour separation records from a transparency, the halftone screen can be automatically oriented and moved into and away from the operative position. In the apparatus shown, light passes through the transparency at 1 to fall on the easel 8, on which is a mask 12 having a central window 13 through which the exposure is made. The easel can pivot upwards on a rail 10. A circular half-tone contact screen 14 is carried in a frame 15, and when not in use is located at one side of the easel, as in Fig.1. The screen itself is mounted on a system of peripheral rings (17, 18, 19), Fig.2 (not shown), the inner ring (17) running in an annular groove on the inside of frame 15. The screen is rotated by bringing a turn-table beneath it up into contact with it. A system of micro-switches controlling a motor drive enables the screen to be rotated automatically into one after another of a predetermined set of positions. The frame 15 is carried at the end of an arm 31 attached to a carriage 24 which slides along a rail 25, its position along this rail being determined by a pneumatic rod and piston arrangement 28, 29. A roller 51 on arm 31 runs along a parallel rail 26. The ends of the two rails are supported in plates 30, 34, which plates can be pivoted by pneumatic pistons 38, 39, so causing rail 26 to be raised. Frame 15, and thus screen 14, is also raised, and carriage 24 can now be moved along the rail to bring the screen into the operative position above easel 8, whence it is lowered on to the window 13. On the other side of the easel from frame 15 is a similar frame 42 carrying a clear screen 41, which is moved into position over the easel, carrying a mask, to define a margin round the developed image. Below the objective lens of the enlarger is a carrier box 4, within which is mounted a rotatable disc (5), Fig. 3 (not shown) having five apertures, four containing filters appropriate to the colour separation set being prepared, and the fifth being empty. The required filter is rotated into position under control from a selector switch 43 on a front control panel 44.
