Title: Improvements in or connected with machines for branding or printing on wood or other surfaces
IPC: B44B7/00
Filed: 1923-10-06
Abstract: 226,304. Cole, W. L. Oct. 6, 1923. Platen machines; branding by heat.-A machine for branding or printing on wood or other plates or boards comprises a bed, a branding or printing head positioned above the bed, means for feeding the boards in succession from an adjustable magazine to the printing- head, resilient means for pressing the printing head on each board, and means for adjusting the feed mechanism relatively to the means for actuating the printing-head to suit different sizes of boards. The printing-head 7, Figs. 1 and 2, is operated by a rod 8 sliding in bearings 9 and reciprocated from a rocking shaft 12 by a link 10 and eccentric disc 11. Movement of the shaft 12 is obtained from the main shaft 14 through a gear wheel 31 carrying a crank pin 30 having a yielding connection with a connecting-rod 26 pivoted to a crank arm 13 on the shaft 12. A divided bearing 27, 27<a> on the connecting-rod 26 engages the crank pin 30, the part 27 being fixed on the connecting-rod and the part 27<a> being slidable thereon but pressed against the part 27 by springs 28. This arrangement permits the pressure of the printing plate on the board to be maintained during printing. The printing-plate is slidably mounted in the head 7 so as to be correctly positioned and may be inked or heated by any suitable means for printing or branding as the case may be. An endless chain 3, intermittently actuated from the gear-wheel 31 through a pawl 39, ratchet wheel 38, and gear wheels 35, 36, carries slats 5 which serve to feed the boards 6 from a magazine 20, having adjustable sides and front, across the bed 2 of the machine, and under the printing-head 7. In order that a set of boards of different size may be fed to correct position beneath the printing-head, the chain 3 can be adjusted relatively to its driving-mechanism so that the position of rest of the slats relatively to the printing-head is set to suit the size of board. For this purpose the driven sprocket wheels 4 carrying the chain are keyed to a shaft 33 having a conical part 34, Fig. 3, fixed thereto with which the conical hub of the gear wheel 35 normally engages frictionally. The wheel 35 is provided with a handwheel 44 and pointer 45, the pointer moving over a graduated disc 46 slidably mounted on the shaft, the disc and gear wheel being held in place by a hand-wheel 48 screwed on the shaft 33, and a spring washer 47. To adjust the chain, the hand-wheel 48 is slackened to disconnect the shaft 33 from the driving gear and the shaft turned by means of a hand-wheel 49. If a board becomes jammed, the shaft 33 becomes fixed, and the gearwheel 35 rotates on the part 34, the spring washer 47 allowing the necessary slipping back of the gear-wheel.

Title: Improvements relating to tyre retreading moulds
IPC: B29D30/54
Filed: 1956-08-15
Abstract: 803,500. Retreading tyres. SUPER MOLD CORPORATION OF CALIFORNIA. Aug. 15, 1956 [May 7, 1956], No. 24995/56. Class 87(2). In a tyre retreading mould, which includes a body 2, 3 having a matrix (not shown) receiving the tyre 10 with its beads 11 exposed, a tyre tread centring device 14 comprises two axially movable rings 34 engaging the beads from the outside and guided by two fixed annular guides 16 within the body 2, 3, the separation of the rings being yieldably resisted by means which move the rings towards each other. The mould body is in two sections 2, 3, and these clamp the heated complementary halves of the matrix assembly which confines most of the outer periphery of the tyre, the beads 11 being free. The means for actuating each ring 34 is formed by one of the annular guides 16 and a slide ring 20, which are both shaped to define an annular expansion chamber 24. Each ring 34 is clamped to one of the rings 20. In operation, a backed inflatable curing bag is placed in the tyre, the sections 2, 3 are bolted together at 8, and equal pressures are applied to the annular chambers 24. The rings 20, 34 are thus urged against the stops 21 on the guides, and when the bag is inflated to force the new tread into the matrix, the outward movement of the beads is yieldably resisted. The tread is thus accurately centred and after vulcanisation the removal of the tyre is facilitated by pressure applied to the lower annular chamber 24 only. Specification 724,495 is referred to.

Abstract: 1,136,868. Pneumatic springs. GENERAL MOTORS CORP. 1 June, 1967 [3 June, 1966], No. 25375/67. Heading F2S. [Also in Divisions D1 and H1] A washing machine (Division D1) has a tub 24 (not shown) rotatable by a drive shaft which, when the tub is unbalanced, initiates the movement of the actuator arm 68 of a switch (62), Fig. 2 (not shown), which movement is controlled by a delay mechanism 80. Mechanism 80 comprises a housing 84, mounted on an arm 82 connected to microswitch (62), having a channelsection flange 86 holding a valve plate 88 with a central opening 90. A bellows 94 has an annular flange 92, seated against plate 88 to form a chamber 100, and an elongated tip 96 held in an opening 98 in arm 68. A flexible check valve element having openings 108 off-set from opening 90 is seated against the opposite side of plate 88 and is held by an annular plate 110 seated in flange 86 against the edge of a diaphragm 116 with which it forms a chamber 120. Thus, when arm 68 is moved towards arm 82 air is forced into chamber 120 and diaphragm 116 is expanded, the resistance of diaphragm 116 causing damping of the movement so that momentary movement of arm 68 does not actuate switch 62. Air will return only slowly from space 100 to chamber 120 so that, when switch 62 has been actuated it remains so for sufficient time.
