Filed: 1954-08-26
Abstract: 777,965. Twisting wires together. POWER & SONS (BOX STRAPPING), Ltd., F. A. Aug. 24, 1955 [Aug. 26, 1954], No. 24891/54. Class 83 (4). A tying machine comprises wire training means for forming a loop of wire in flat band form about an object to be tied, tensioning means for tightening the wire loop about the object, tie forming means for twisting together superposed overlapping ends of the wire loop. and finger means movable for insertion between the overlapping portions to cause the ends of the loop-to intersect at a point away from the slot of the pinion. In operation, a gripper 14 is moved from a position to the left of a twisting pinion 16, Fig. 2, to a position adjacent a gripper 15 to the right of the twisting pinion, as described in Specification 523,786, [Group 1], to which reference is made. The gripper 14 is closed on the end of a flat wire W projecting from the gripper 15 which latter is then opened and the gripper 14 is swung out, moved in front of the twisting pinion 16, and swung in again to lay the wire in the flared slot of the pinion 16. During this latter movement the wire engages a shoulder 307, Fig. 10, on a pivoted finger 300 and lifts the finger to the position shown in Fig. 10. The gripper 14 is then halted, a box B placed on a supporting frame 10 and ring means 11, Fig. 1 (not shown), carry the wire around the box as in Specification 523,786. Towards the end of the revolution of the ring the wire is laid on the underside of the finger 300, to cause the ends of the loop to cross at a point X between the finger and the gripper 14, and the supply end of the wire enters the slot in the twister 16 to lie face to face with the wire previously laid therein. The gripper 15 is advanced just before the end of the revolution of the ring 11 to receive the wire supply between an open jaw 316, Fig. 3, and the body 100 of the gripper. The jaw is then closed by a roller 322 on a link 116 and the other gripper 14 moved to the left to tension the wire. Separators 170, Figs. 2, 13, are then moved down to pass between the overlapped wire ends at each side of the twister 16 and fork members 301 are then moved down between the separators 170 and the twister 16 to hold the overlapped ends closely together. The twister 16 then rotates to form the tie and the ends of the loop are severed by cutting edges 315 on the separators 170 by retraction of the separators. The separators 170 are then advanced to eject the tie from the twister 16.

Abstract: 733,184. Moulding-machines BROWN & SONS (HUDDERSFIELD), Ltd., D. Feb. 1, 1954 [Nov. 3, 1952], No. 24912/52. Class 83 (1). A method of producing hollow cores from a sand-resin mixture comprises temporarily closing the outlet opening in the bottom of a heated core-box, blowing a charge of sand-resin mixture downwardly into the box through an inlet opening in the top thereof, and then transferring the filled box to a station at which the outlet is opened and 'the inlet is brought into operative contact with a supply of compressed air which blows out the surplus uriset material in the bbx through the outlet. A machine for carrying out the method comprises an electric motor a driving, through worm gears c, a vertical shaft d which drives, through mitre gears f, g, j respectively, horizontal shafts h, i, k carrying cams h<SP>1</SP>, i<SP>1</SP>, q respectively. The cam q actuates one arm of a bell-crank p whose other arm p<SP>4</SP> moves a series of heated oore-boxes r intermittently between guide rails (not shown) along the top m<SP>1</SP> of the machine base m, and the cam i<SP>1</SP> lifts a table m<SP>3</SP> located in a gap in the base m. A filling mechanism t, operated by the cam h<SP>1</SP>, and a compressed air line u, are located above the path of the core-boxes r. In operation, whilst one of the boxes is being pushed under the filling mechanism t by the arm p<SP>4</SP>, the cam h<SP>1</SP> opens a valve t<SP>1</SP> to allow a predetermined charge of sand-resin mixture to be fed into a blowing chamber t2. The camoperated table m3 then lifts the empty box into contact with a filling nozzle t3 and simultaneously the cam h<SP>1</SP> opens a valve t<SP>4</SP> in the nozzle and a slide-valve t<SP>5</SP> to allow compressed air supplied at u<SP>1</SP> to the hollow-spindle of valve t<SP>4</SP> to pass into the chamber t<SP>2</SP> and thereby fill the box. The table m<SP>3</SP> supports two boxes and in addition to lifting an empty box for filling as just described it also lifts a previously filled box, the top of which automatically contacts and opens a spring-loaded valve in the air line u and the surplus material in the box is thereby blown out through a flexible pipe v fixed to a hole m<SP>5</SP> in a top plate m<SP>6</SP> of the table m<SP>3</SP>. At each stroke of the arm p<SP>4</SP> a completed box r is delivered to a conveyer-belt 8 for transmission to a curing oven. Means are provided to enable the machine to accommodate different sizes of boxes. For variations in height, the mechanism t and compressed air line u are mounted on a vertically-adjustable slide b and the driving gear of the mitre gears f is splined on the shaft d, and for variations in length, parts m<SP>6</SP>, m<SP>7</SP> and m<SP>8</SP> and cam q are changed for others of appropriate size and the air line u is laterally movable in a slot w.

Title: Improvements in rotary and percussive rock drills
Inventor: HAUSHERR RUDOLF
IPC: E21B6/00
Filed: 1954-08-27
Abstract: 794,480. Percussive drills. HAUSHERR, R., HAUSHERR, G. and HAUSHERR, H., [trading as HAUSHERR UND ERBEN KOMMGES., R.]. Aug. 27, 1954, No. 24964/54. Class 124. A rock drill comprises a rotatable drill steel, a motor and shaft rotating a drill steel sleeve adapted to have a limited axial movement with respect to the shaft, and a percussive device located between the motor and the sleeve and acting on the sleeve in such manner that the rotary movement of the shaft is unaffected. As shown, an electric motor 1 drives a shaft 18, 17b, 17a and a sleeve 6 carrying a steel 4. The sleeve 6 has a slot 23 longer than a key 21 on the shaft thus allowing the sleeve a limited axial movement on the shaft. A pneumatically operated piston 25 mounted on a part 24 of the sleeve strikes blows on a shoulder 26 and a second piston 29 mounted on the part 17b of the shafts also strikes blows on a shoulder 31 on the sleeve, the pistons being arranged so that they strike alternately. The pistons are mounted in cylinders 27 and 28 which are separated by a wall 32 in which is provided the valve gear for distributing the pneumatic medium to the pistons. Specification 794,481 is referred to.

Title: Improvements relating to the control of rolling machines
IPC: B21H1/02
Filed: 1955-08-31
Abstract: 776,592. Rolling wheels and discs. GENERAL ELECTRIC CO. Aug. 31, 1955 [Oct. 6, 1954], No. 24997/55. Class 83 (4). In a machine for rolling wheel blanks 16, Fig. 5, by pairs of rolls 40, 42, 44, a control mechanism is provided for co-ordinating the progressive pass adjustment of the rolls with the radial traverse of at least one of the roll pairs 42 as the diameter of the blank increases. The mechanism is used in a machine such as that described in Specification 776,227 in which a pair of rolls 40 forms the inner edge of the web e, Fig. 6, and another pair 44 form the rim f and a third pair 42 moves progressively outwardly as the web e increases in diameter. The blank 16, Fig. 1, is clamped between jaws 18, 20 under the action of an hydraulic cylinder 21 and is rotated by a motor 10 which drives a shaft 12 carrying the jaw 20. The rolls 40 are driven through a gear-box 92 from a motor 90 which is speed controlled so that the speed of the roller equals the surface speed of the blank 16. The pass adjustment means of each pair of rolls comprises an hydraulic cylinder 45 actuating a toggle device 41 as described in the above Specification. Movement of the cylinder 45 is controlled by an hydraulic servo-mechanism 50 carried by a slide 47 and moved in accordance with the required reduction in thickness by means of a cam 74 driven through a reduction gear 70 from the shaft 12. An adjustable reducing valve 83 in a circuit for the amplifier 54 of the servo-mechanism protects the rolls against excessive mechanical forces. A pressure-operated switch 32 in the clamping circuit is electrically interlocked with all the driving motors so that rotation of the wheel blank 16 is prevented before it is securely clamped. Differential pressure switches 80 in the servo-mechanism circuits are also interlocked with magnetic clutches 76 in the drives for the cams 74 so that all three units start simultaneously. Radial movement of the rolls 42, Fig. 2, under the action of hydraulic cylinders 100 is similarly controlled by a cam 108 actuating a servo-mechanism 105 carried by the roll frame 101.

Title: Tyre vulcanising press
IPC: B29D30/06
Filed: 1969-05-16
Abstract: 1,256,262. Moulding tyres. A. HERBERT and M. GUHR, [trading as LEONHARD HERBERT, MASCHINENFABRIK]. 16 May, 1969 [17 May, 1968], No. 25159/69. Heading B5A. A tyre press with provision for vulcanizing tyres of different size which may be required to be re-treaded with one and the same heating bag includes an upper mould part 4 movable downwardly on to a lower mould part 6, a heating bag 18 locatable, when folded double, between cylinders 15, 17 and its edges clamped to the inner one, pressure fluid cylinders 12a, 12b acting on the base of the outer cylinder when the press is open to raise it to eject a tyre from the lower mould half, and a locking device for holding the inner cylinder at a predetermined level depending on the tyre size. The locking device may comprise a rod 27 depending from the base of the inner cylinder and clamped by a sleeve K secured to the press base. With the press open and the cylinders in position to receive an unvulcanized tyre, a seat ring 16 on the outer cylinder receives the tyre 59 whereupon an upper seat ring 48 secured to a cylinder 47 is driven downwardly relative the upper mould part by a fluid cylinder 44, and passes over the inner cylinder until a rod 51 depending from the cylinder 47 abuts a rod 36 upstanding from the inner cylinder base. The outer cylinder is thereby forced downwardly and slides along the bag which is guided into the tyre cavity by the ring 48; a little inflation pressure is simultaneously applied to the bag via passages 34, 35. When the ring 48 engages the upper bag clamping ring on the inner cylinder the upper mould half closes on to the lower mould half, and the cylinders 12a, 12b are actuated to move the cylinder 15 downwards slightly to bring the seat ring 16 into contact with the lower mould half. Pressure is then built up in the bag and vulcanization effected. Tyres of different sizes may be treated by replacing the mould parts 4, 6 and tyre seat rings and varying the height of the inner cylinder 17 with its associated bag clamping rings; for the latter purpose the rod 27  is unclamped from the sleeve K whereupon a compression spring 30 urges the cylinder 17 upwardly so that when the press is closed with the new mould parts in position the bag clamping rings take up a new position in which they are fixed by re-clamping the rod 27 by the sleeve.

Abstract: 649,087. Dispensing liquids. S. A. T. A. M. SOC. ANON. POURS TOUS APPAREILLAGES MECANIQUES. Aug. 28, 1946, No: 25793. Convention date, Nov. 26, 1940. [Class 116] [Also in Group XXIX] In apparatus for measuring and dispensing liquids, including a predetermining mechanism which is preset and then driven by the liquid flow, a differential-pistonactuated main valve controls the bulk of the predetermined quantity of liquid and an auxiliary valve, in a restricted byepass in parallel with and controlling the main valve, is mechanically controlled by the predetermining mechanism to open at the beginning, partially close towards the end and completely close at the end of the dispensing operation. The spring-loaded auxiliary valve 5, Fig. 1, operated through a lever 25 by a cam 21 driven by the predetermining mechanism, controls the flow of liquid from the inlet 8 through the orifice 13 in the piston 2 attached to the main valve 1 and through the conduits 22, 23 byepassing the main valve to the outlet 6. On partial, closing of the auxiliary valve pressure builds up behind the piston and closes the main valve so that a dribble occurs through the orifice and auxiliary valve before the latter finally closes. The Specification as open to inspection under Sect. 91 describes a differentialpiston-actuated main valve controlled by a manually-operated needle valve on the main valve casirig and also a filling nozzle. The filling nozzle 41, Fig. 7 (Cancelled) is controlled by a spring-loaded valve 32 mounted on a hollow tube 33 carrying a piston 34. On lifting the valve by manually operating a lever 38, a light auxiliary valve 36 in the tube is lifted on to a pin 37 so that the valve is raised from its seat 63 within the tube when the lever is released. Pressure acting behind the piston via the orifice 71 is thus relieved and the main valve opens. When the liquid level in the receiving vessel closes a bell 39, air pressure moves a diaphragm 91 which withdraws the pin and allows the auxiliary valve and consequently the main valve to close. This subject-matter does not appear in the Specification as accepted.

Abstract: 951,785. Selective signalling systems. LICENTIA PATENT VERWALTUNGS G.m.b.H. July 27, 1960 [July 29, 1959], No. 26127/60. Heading G4H. In a machine-tool control system, coarse control of motor 3, Fig. 1, is effected by a digital servo system including a comparator 8, and fine control of motor 3 is effected by an analogue servo system. Motor 3 drives a coded disc 2 and also a device 1 which produces an analogue voltage representing the shaft position within the range covered by one division on the least significant track of disc 2. Disc 2 besides carrying binary coded tracks 1-3, Fig. 4, also has two control tracks A, B, the divisions of which are equal to one half the divisions of track 1 and are displaced from each other by one quarter of a division, this corresponding to 25 units in the example shown where each division of track 1 corresponds to 100 units. Tracks 1-3 are sensed by lead and lag devices 21a, 21b-23a, 23b and tracks A, B are sensed by devices 19, 20 which are displaced from the centre line 18, preferably by 12. 5 units. Disc 2, Fig. 1, supplies comparator 8 with signals from tracks A, B as well as the binary-coded tracks, and a logic circuit 10 supplied with the two least significant decimal digits of the desired position determines which of tracks A and B is to be effective, track A being selected for the first and third quarters of a division of track 1 i.e. 0-24 and 50-74 units, and track B being selected for the second and fourth quarters, i.e. 25-49 and 75-99 units. The two least significant decimal digits are further supplied to an analogue to digital converter 7, and the sum of the voltages from converter 7 and device 1 is supplied to contact 6b of switch 6. Circuit 10 ensures that the zero output from comparator 8 occurs when the motor shaft is about 25 units from the desired position, switch 6 then operating to select contact 6b for control of motor 3 and reducing the motor speed to avoid overrunning.
