IPC: B29D5/02
Filed: 1939-04-06
Abstract: 527,373. Making casting or press moulds; forging-machines. WINTERHALTER. M. O. April 6, 1939; No. 10855. Convention date, April 12, 1928. [Classes 83 (ii) and 83 (iv)] The recesses 27, 28 in a casting or press mould for making the interlocking members of a sliding clasp fastener are made by pressing. The bulges produced on the surface of the mould are removed by grinding. There are about 20 pressing stages such that after the first stage the recesses have attained one-third of the final depth and after a half of the pressing stages they have attained fourfifths of the final depth. Grinding occurs after each or a number of pressing stages. A groove is milled in the lower mould 20 between the recesses and connects with a casting channel bored in the upper mould 21. Grooves for the stringers to which the members are moulded are also provided in the moulds. The recesses are formed by a die 50 operated by an eccentric, the mould being held by dowels 67 and jaws 69 on a slide 54 clamped during pressing by screws 55 to the bed 52 of the press. The slide is counterbalanced by a weight 70 and carries a threaded spindle 58 engaged by a locking pawl 60 and a pawl 59 which may be operated to move the slide by a bell crank lever 62 with a handle 64.

Title: Improvements in or relating to collapsible umbrellas
IPC: A45B25/06
Filed: 1957-04-03
Abstract: 804,619. Telescopic umbrellas. BREMSHEY, F., and EICKHORN, K. H., '[trading as BREMSHEY & CO.]. April 3, 1957 [April 3, 1956], No. 10914/57. Class 134 In an umbrella with telescopic ribs and stem, struts pivoted to a main slider and braces s pivoted to an auxiliary slider, a catch mounted on the auxiliary slider with a retaining means on the crown part of the stem to prevent movement of the auxiliary slider along the stem during the initial stage of spreading the ribs. In the construction shown the telescopic ribs 13, 14 are pivoted to a crown 17 mounted on the telescopic stem 1, 7. Struts 15 are pivoted to hinges 16 connected to the rib parts 14 and to a main slider (not shown). Braces 6 are pivoted to the struts 15 and to an auxiliary slider 2 by means of a wire 10 housed in a peripheral recess in the auxiliary slider 2. A catch 3 is also pivoted on the wire 10. The limbs of a U-shaped spring 4 are connected to U-shaped members 5 clipped over each of two adjacent braces 6, while the transverse part of the spring is passed through an opening 18 into a slot 9 formed in the catch 3. To open the umbrella the main slider is pushed towards the crown 17, thus moving the auxiliary slider 2 and the hinge 16 towards the crown until the catch 3 is pushed into a hole 8 in the crown part 1 of the stem by pressure of the spring 4 against the side of the slot 9 so that further movement of the auxiliary slider 2 is prevented. Further movement of the main slider towards the crown 17 spreads the ribs 13, 14 until the transverse part of the spring 4 reaches the bottom of the slot 9, whereupon the spring 4 is placed under tension and withdraws the catch 3 from the hole 8. The main and auxiliary sliders are then moved towards the crown 17 until the frame is fully erected. In this position the auxiliary slider 2 may abut the crown 17 and. may be made of such a length as to be abutted at its lower end by the main slider, thus enabling the bulge sometimes provided on the stem to limit the crownward movement of the main slider to be omitted. When extending and telescoping the frame, the handle part 7 of the stem lies behind the hole 8 and prevents entry of the catch 3.

Abstract: 496,455. Pneumatic tyres ; covering cores. DUNLOP RUBBER CO., Ltd. April 12, 1938, No. 11141. Convention date, April 14, 1937. [Class 144 (i)] [Also in Group XXV] An annular core for use as reinforcement for a circumferential edging, particularly a tyre-bead wire, is covered with a fabric strip which is fed longitudinally on to said core from outside the plane of the annulus. In the apparatus shown, a bead ring 75 is tensioned between two grooved pulleys 1, 2, the former of which may be moved vertically along a standard 16 by a handwheel 16a, to accommodate rings of different sizes, and the latter being driven by an electric motor. The fabric 76 passes from a supply roller 39, over festoon rollers 31, 30, 40, and then between rollers 36, 37, to a horizontal table 22 arranged at an angle with respect to the plane of the pulleys 1, 2. The end of the table is furnished with a roller 5 provided with a circumferential groove 66 which initiates the folding-over of the edges of the fabric strip, as shown in Fig. 2, when the fabric passes over the roller 5 into contact with the bead wire. The partially folded fabric strip passes around the pulley 2 and then through a former 6 which completes the shaping of the strip. After passing over the pulley 1, the end of the fabric strip engages with a spring-loaded pivoted member 45 which is thereby disengaged from a member 51 to break an electric circuit and stop the machine. The requisite length of fabric to complete the covering of the wire is then cut off by means of hand or mechanically operated shears 25, which latter may be arranged to operate a clutch in the transmission system between the driven shaft 7 of the roller 2 and the rollers 39, 31, 30, 40, 36. The machine is restarted to complete the folding of the fabric strip around the bead wire by depressing a foot pedal. The machine may be stopped to permit the severing of the correct length of fabric strip, by the end of the latter, after passing over the pulley 1, interrupting the light beam of a photo-electric cell control device. Strips of rubber or the like for incorporation in the bead structure may be supplied from rollers 41, 34, 35.
