Abstract: 892,771. Suction work holders. VACUUM INDUSTRIAL APPLICATIONS Ltd. Oct. 14, 1960 [July 18, 1959], No. 24759/59. Class 60. A machine for treating plates, e.g. edge planing and shearing, includes a table incorporating at least one sucker head located to be engageable with the surface next the table of a plate applied to the table in which the sucker head is coupled to one end, of a piston rod the other end of which is coupled to a piston slidable in a cylinder, the piston rod penetrating a cover closing the cylinder at one end, the portion of the cylinder between the cover and the piston being connectable to a source of supply of operating fluid under pressure. The table 1 is formed with recesses 2 in which are located sucker heads 3, each head comprising a backing member having a wall 4, a resilient ring 5 and a clamping member 6 holding the ring 5 to the backing member. The head is attached to a hollow rod 7 penetrating a hole in the table co-axial with the recess 2; the rod 7 passes through a cylinder 8 and carries a piston 9 slidable in the cylinder. The interior of the rod 7 communicates with a pipe 10 connectable to evacuating means. The portions of the cylinder on opposite sides of the piston are connectable to a supply of pressure fluid by pipes 11, 12.

Abstract: 408,869. Ironing presses. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Watts, N. H. ; Toilsome Hill Road, Bridgeport, Connecticut, U.S.A.) Sept. 8, 1933, No. 24949. Convention date, Sept. 9, 1932. [Class 138 (ii).] The head of an ironing-press is secured to angle-brackets 17, Fig. 6, secured to parallel arms 18 which are pivoted to interconnected spaced U-shaped frames 19. The carriage formed by the frames is provided with wheels 24 and runs on guides in the base 11, Fig. 5, beneath the buck, an extension of the guides being formed in a pivoted back wall 44 which can be lowered to permit the carriage to be moved back so that the head is no longer over the buck. Arms 28, Fig. 6, are pivoted about one of the cross rods 26 connecting the frames 19 and the free ends of the arms bear on rollers 37, Fig. 7, which are positioned between guide frames 34 secured to the arms and plates 32 slidably mounted therein. A cam bar 29 is pivotally connected, by means of staples 31, 33, to the angle-brackets 17 and to the plates 32 and is rotated by a handle 30 for lowering the head into pressing-engagement with the buck. When a predetermined pressure is exerted between the head and buck pre-stressed springs 39 acting on the arms 28 yield, permitting the latter to rise to prevent such pressure being exceeded. During the application of pressure a limited pivotal movement of the carriage takes place, raising one of the cross bars 25, Fig. 6, which is relatively heavy, into engagement with the rectangular centre post 7 forming part of the buck structure, whereby the post takes and transmits some of the pressing force exerted. The head, which is preferably made of aluminium, is provided with a separate electric heating element for each end, each element having its own independently adjustable thermostat which may be of the type described in Specification 280,323, [Class 64 (ii)]. The heating elements are cast in heavy ribs formed on the inside of the head and these ribs are interconnected by longitudinal and transverse ribs to ensure uniform heating. The perforated plate which supports the padding of the buck is also preferably formed of aluminium and is reinforced by longitudinal channel irons which are curved, their ends being higher than the centre to ensure that when the head contacts with the buck the ends yield so as to give uniform pressure. An apron 52 shaped as shown in Fig. 5 is pivoted to the base 10 which forms a continuation of the plate 4 secured to the underside of the buck and is resiliently held vertically to form with the base 10 a pocket 53 wherein the material being pressed can be received. Specification 379,689 also is referred to.
