Title: Improvements in Machines for Rounding or Trimming the Edges of Boot or Shoe Soles.
Inventor: SCHOENKY AUGUST RUDOLF
IPC: A43D29/00
Filed: 1917-08-29
Abstract: 118,456. Sehoenky, A. R. Aug. 29, 1917. Trimming and channelling.-In a sole-rounding machine, such as of the type described in Specification 7684/13, the usual work-clamping and feeding devices are operated for feed and return by link and lever connexions with a crankshaft, the work-clamping movement being controlled by a cam-operated lever of very slight movement. The revoluble work rest B, Fig. 4. is carried by a spring-pressed slide b<4> mounted in a swinging arm 11 pivoted about a stud 10, as usual, while the work-clamping member D is carried as usual by a bell-crank d<2>. The grooved hub of this bell-crank is surrounded by a split collar 19 pivotally connected by a link 18 to an arm 14 loosely mounted on the stud 10, and to provide for relative adjustment between the workclamping and feeding devices, the arm 14 is formed with rearwardly-extending lugs 15, Figs. 3 and 4, threaded to receive adjusting-screws 16, which are set against the opposite faces of a square-headed stud 17 swivelled in a flange 13 on the hub 12 of the swinging arm 11. To effect the feed and return movements of the work-clamping and feeding devices, the arm 11 has pivoted to it one end of a toggle 22, 23, Fig. 3, the other end of which is pivoted to the side frame A<2> of the machine, while its joint is pivotally connected by a compound link 25, to a lever 26 fast on a rock-shaft 27. The other end of this shaft has secured to it a lever 28, Fig. 5, pivoted to one end of a toggle composed of a short straight link 29 and a longer curved link 30, the end of which is pivoted to a stud 31 on the side frame of the machine. The joint 32 of this toggle is loosely connected to a pitman 33 which surrounds a crankpin 34 on a shaft W. The clamping and releasing movements of the member D are controlled by a roller 20, Fig. 4, carried by a rearwardlyextending arm d<5> of the bell-crank d<2> and running in a cam 21 on the shaft W. With this construction, the work-clamping and feeding devices receive a long feed movement and a quick return movement, and between these movements there are two periods of substantial rest, during which the member D receives its work-clamping and releasing movements. This is illustrated diagrammatically in Fig. 9.

Title: Improvements in or relating to the manufacture of pneumatic vehicle tyres
IPC: B29D30/34
Filed: 1960-04-08
Abstract: 901,599. Pneumatic tyres. CONTINENTAL GUMMI - WERKE A.G. April 8, 1960 [April 13, 1959], No. 12501/60. Classes 144 (1) and 144 (2). A pneumatic tyre is made by assembling two cylindrical carcase sections, each comprising a reinforcing ply 4 looped around a singlebead core 3, on a former 10 of generally tyreshape in section, in such a manner that the radially outer layer of the ply 4 in the cylindrical section is disposed on the radially inner side of the section in the assembly on the former. The carcase sections may be made on an expansible drum and ply-end turnover apparatus such as described in Specification 733,206 to form first a two layer ply pocket with a bead core at each end, the pocket being circumferential severed, as shown in Fig. 2, to provide the two sections. Assembly of the sections may be effected by the apparatus as described in Specification 851,617, Fig. 3. Application of the carcase sections to the former 10 by the shapers 8, 12 and 9, 12 may be effected conjointly with application of the side wall rubber stops 15 which are initially desposed on each collapsed cylindrical shaper assembly prior to the disposition thereon of the cylindrical carcase section. In the assembled tyre blank, the free ends of each section overlap in the crown region of the former. Tread rubber strip is then applied to the assembly which is then removed and moulded to provide the finished tyre shown in Fig. 5. In an alternative arrangement, the ply turn-over at each bead core may be sufficient only for ply anchorage, providing in effect a single layer carcase section, but assembly of such sections is still effected so that the ply turn-over in the cylindrical section becomes a ply turn-under, or vice versa, in the assembled blank. Additional sections may be assembled if the required tyre is to have more than one core in each bead.

Filed: 1971-05-05
Abstract: 1302821 Water & soap supplies AMERICAN STANDARD Inc 5 May 1971 [8 June 1970] 13175/71 Heading A4N A sanitary appliance, such as a wash basin BA, Fig.2, has means for dispensing water, means for dispensing soap, and means responsive to the arrival of a user at the basin for dispensing water for a first predetermined interval and for dispensing soap for a second predetermined interval commencing after the start of the first interval. The intervals may be equal or unequal and may overlap. Supply of soap is followed after a third predetermined interval by the supply of more water until the user moves away. The soap and water may issue from a common faucet but preferably issue from outlets SF and ST respectively. The proximity detector may be photoelectric but is preferably capacitative having a sensing member ANT. A CONTROL DEVICE controls a solenoid valve SV in the water supply line and a soap pump SP and includes relays L 1 -L 4 , Fig.3, and transistors Q 1 -Q 5 . Initially all relays are off, transistors Q 1 -Q 3  and Q 4  are off and transistors Q 2  and Q 5  are on. When a user arrives the charge in capacitance of member ANT is sensed by a control CN causing relay L 2  to switch on valve SV to supply water for a period determined by delay circuit DLI after which transistor Q 4  switches on, transistor Q 5  off, relay L 1  switches on and valve SV closes. Operation of relay L 1  operates relay L 4  switching on a motor MO of the soap pump for a period determined by delay circuit DL2 after which transistor Q 1  switches on, transistor Q 2  off, relay L 3  operates and relay L 4  turns off stopping motor MO. After a further delay caused by circuit DL 3 , during which neither soap nor water is supplied, transistor Q 3  turns off, transistor Q 5  on, and relay L1 operates opening valve SV to supply water until the user departs. A "soap" light SL operates from the arrival of the user until cessation of soap supply whereupon a "rinse" light RL operates until the user departs. (For Figures see next page)
