A door latch comprises a forked latching member 26 mounted on a plate 11 on a door when the latch is in use, to pivot into and out of position for straddling and latching engagament with a keeper 14 on the door frame the latching member having holding means fixed relative thereto to pivot therewith, a detent unit 41 releasably engageable with the holding means to positively but releasably hold the latching member in latching engagement with the keeper member and spring means 36 urging the latching member and the holding means out of the position of latching engagement when the detent unit is released from the holding means, the latching memiber when in the position for latching engagement having a loot portion 58 snugly nested about the keeper 14 so that the latching member is restrained against movement in one vertical direction, and an actuating arm 56, and a holding arm 57 with an inclined holding surface 60 adapted to engage the keeper member so that the latching member is restrained thereby against movement in the opposite vertical direction. As described the latching member 26 is secured to one end portion 22 of a stem passing through the plate 11 and the holding means is a plate secured to the other end portion of the stem. The plate carries teeth 29, 30 engageable by a detent arm 48 forming part of the detent unit 41, so that the latching member can be held in either the fully latched position, shown in solid lines, or in an intermediate safety latched position. In the fully latched position the surface 60 forms an angle of 45‹ with the direction of relative movement D of the door and frame members. The latch is released by actuating an operating extension 45 on a bell-crank member 44 which engages with and pivots a plate 42 bearing the detent arm 48 to disengage the latter from the-tooth 29.

Abstract: 906,640. Portable stapling machines. HAUBOLD, D. Dec. 23, 1958 [Dec. 24, 1957], No. 41522/58. Class 89 (3). A portable pneumatic stapling machine includes a pistol grip handle disposed laterally to and extending at right-angles from a stapledriving operating cylinder, the handle being formed by at least two separate portions, a first portion of which constitutes in part an air inlet passage for the cylinder and a second portion of which is adapted to be fixed to the first portion and provides a housing for trigger means for a valve carrier by the first handle portion, the valve being operable by the trigger to open communication between the air inlet passage and the cylinder. In one embodiment, air admission ports 32, 33, Fig. 2, valve seat 35, pneumatic cylinder 37 and exhaust port 34 are formed as a single body 31 strengthened by webs 41, 42, housed between symmetrical halves, Figs. 4 and 5 (not shown), of a handle portion which have reinforcing ribs provided with recesses in which the body 31 is mounted. The two parts of the handle portion may be connected together by screws. In a modification the body 31 may be in two symmetrical halves held together by the two parts of the handle portion. In a further modification, Fig. 6 (not shown), the two halves of the handle portion are downwardly extended to form a casing for the staple &c. magazine, but they do not enclose the cylinder 37 of the body 31. In a further embodiment, the handle is formed by an upper portion 71, Fig. 7, containing air ports 72, 73, valve housing 74 and cylinder 75 and including reinforcement ribs 76, 77, and a lower portion 81, Fig. 8, comprising the bottom part of the machine having a downwardly-facing handle surface and a flat lower portion 83 having two longitudinal ribs 84 to hold a staple magazine. The upper and lower parts 71, 81 are secured together by screws together with a staple trackway and magazine bottom to form a complete body, Fig. 9 (not shown).

Abstract: 1,119,705. Welding by pressure. R. THOMAS & BALDWINS Ltd. 29 Sept., 1965 [12 Oct,. 1964], No. 41563/64. Heading B3R. In resistance spot-welding metal sheets or strips coated with insulating material, a flange is formed at the edge of each sheet or strip, the flanges are contacted, and welding electrodes apply current and pressure to the limbs of a U-shaped capping piece placed over the flanges or to the limbs of a U-shaped internally coated flange, having the flange on one of the edges and embracing the flange on the other edge. Flanges formed on the edges of metal sheets coated on both sides as shown, or on only one side, with paint or plastic films 3, 4, 5, 6, are contacted and and a U-shaped metal capping piece 9 is placed over them and is contacted by spot-welding electrodes 10, 11. The capping piece may extend the length of the flanges or may be in a number of pieces and may be of galvanized or ungalvanized mild steel or of aluminium if the sheets are of steel or aluminium, respectively. In a modification, sheets coated on only one side have flanges formed thereon, the coating being arranged between the contacting flanges and one flange is bent down over the other in U-form. The electrodes are placed against the uncoated sides of the U-shaped flange to effect welding. The current passed through the capping piece or U-shaped flange heats up the piece or flange and causes localized heating under the electrodes which softens and melts the coating. The electrode pressure squeezes out the coating to allow metal to metal contact for welding.

Abstract: 1,003,262. Feeding sheets. C.J. HEYWOOD. Jan. 27, 1964 [Nov. 2, 1962], No. 41595/62. Heading B6B. In sheet feeding apparatus wherein a depleted stack of sheets is replenished without interrupting the sheet separation and feeding, a main stack hoisting mechanism and an auxiliary hoisting mechanism are provided which are each capable of producing continuous upward movement in response to a downward displacement of a feeler engaging the top of the stack. As shown, sheets can be separated from the top of the stack 3 by oscillating suckers 10, and an adjustable feeler 12 resting on the stack can operate a control switch in a circuit which includes two motors, one motor (9, not shown) adapted to operate on chains 8 to lift the main table 5, and the other motor 24 serving to lift by chains 23 an auxiliary hoist comprising a pair of cross-bars 22. The main table 5 is supported by cross-bars 7 and has recesses 6. In operation, with the stack 3 still supported by the main table 5 and nearly exhausted, rods 25 provided with head portions are thrust into the recesses 6 beneath the stack 3, the motor 24 is started to raise the bars 22 to a position just below the rods 25 and a further switch is operated to cut out the feeler 12 and its switch from the circuit of the main motor (9), and include it in the circuit of the motor 24, whereupon the auxiliary hoist takes over. A switch is now operated to cause the main motor to lower the table 5 to receive a new sheet stack 4 (as shown). At this stage, a wooden wedge 26, comprising a number of spaced wedge-shaped fingers held together by a back 28 which is situated below the plane of the fingers, is inserted below the bottom sheet of the depleted stack 3, and the main motor is then started to raise the top of the new stack 4 nearly into contact with the rods 25. The feeler 12 and its mechanism is now switched into the main motor circuit, and the stack 4 is thus raised to engage the rods 25 and lift the stack 3. The rods 25 can be withdrawn slowly, and later the wedge 26 is withdrawn, all these operations being performed without interrupting the sheet feed.
