Title: Improvements in, or relating to, the construction of, boxes or cases such as used for containing electric switches, fuses, and the like
IPC: H05K5/00
Filed: 1929-06-13
Abstract: 336,618. Crabtree, J. A. June 13, 1929.

Patent GB-1206071-A (GB)
Title: Bread toaster
IPC: A47J37/08
Filed: 1968-04-17
Abstract: 1,206,071. Toaster. PHILIPS' GLOEILAMPENFABRIEKEN N.V. 17 April, 1968 [20 April, 1967], No. 18156/68. Heading A4D. [Also in Division B8] In a bread toaster, a movable conveying member 3 of inverted U-form and provided with teeth 3a slidably houses a T- shaped beam 1 which, due to supports 4 located in slots 4a, 4b has limited horizontal movement within the member 3. A compression spring 7 engages an H-shaped member 6 which slides in a slot 7a and which is normally urged downwardly against pins 11. A further spring 17 urges the beam 1 to the left within the members 3, as shown in Fig. 1. The upper bounderies of slots 2 form a stop for the beam 1, 1a, 1b, and the action of a stop 8 on the member 3 is adjustable by a manually rotatable cam 9. A crank pin 12 is motor driven via gearing 15, 16. In operation, bread slices 20 are placed on a plate 19 of the toaster and when the crank is rotated from the Fig. 1 position, the beam 1 and hence the conveying member 3 move upwardly and to the left, lifting the bread 20 until the beam portions 1a, 1b, abut the upper ends of the slots 2. The member 3 is next urged to the right by the action of the crank 12 in the slot 7a while upward movement of the crank 12 is permitted by compression of the spring 7. This travel to the right, against the pressure of the spring 17, is limited by the adjustable stop 8, which thus controls the displacement of the bread 20 per revolution of the crank. The bread 20 is guided by plates 21, which may be of quartz glass, and is toasted by column-like heaters 23 provided with reflectors 25. In a further embodiment, Fig. 5, a member 28 slidable in an opening 32 in the beam 1 is normally urged to the left by a spring 29. The beam 1 is first moved to the left by the crank 12 which, with its vertical movement, engages a spring rod 31 to move the beam to its upper limit. The rod 31 then flexes during the further upward movement of the crank 12 which, in moving to the right, moves the slidable member 28, together with the beam 1.

Abstract: 446,380. Coke ovens. OTTO & CO., GES., DR. C., 9, Christstrasse, Bochum, Germany. June 25, 1935, No. 18191. Convention date, June 25, 1934. [Class 55 (i)] Apparatus for forming vertical holes in a coke oven charge 2 comprises mandrels 9 which have both their upper and lower ends tapered, and are of a length not greater than the height above the oven cover of the coal hoppers of the charging car. Each mandrel may be fixed to the end of a rod 33, which may be hinged back when raised, and which carries an annular body 34 which lies on a metal ring 7 at the top of each passage 4 which is closed thereby. A car running on wheels 8 carries a number of mandrels for making simultaneously all the holes in an oven charge, each mandrel being suspended from a rope 10 passing over a pulley 12, and being wound on a drum coaxial with a wheel 15 driven by gearing from a motor 30. When making the holes, a friction clutch 21 is disengaged by rotation of a hand wheel 22, and, by loosening a brake 16, the shaft 14 carrying the drums is released so that the mandrels fall and penetrate the charge by their own weight.

Abstract: 1,064,301. Conveyer systems; propelling vehicles. A.J. INDUSTRIES Inc. April 30, 1965 [June 5, 1964], No. 18377/65. Heading B7L. A conveyer for propelling an automobile in a forward direction through, e.g., a washing apparatus, comprises an endless chain C, Fig. 6, mounted in a pit in the floor and provided at intervals with carriages 32 each mounting rollers 30 which on the forward flight of the conveyer pass between flow-mounted guides 25, Fig. 1 (not shown), for the wheels at one side of the automobile so as to engage behind the front or rear wheel, as the case may be, and thus propel the automobile through the apparatus. The upper periphery 50, 61 of the rear part of the carriage 32 is inclined, Fig. 4 (not shown), whereby a wheel may be driven over the carriage and rollers 30 to operatively associate the wheel with the conveyer. If the vehicle is inadvertently left in gear or with the brake applied the carriage and roller will pass under the wheel which is merely lifted. The carriage comprises portions 55, 65, Fig. 4 (not shown), securable together by screws 70, 71 to detachably connect shaped parts 68, 57 between barrels 58 of chain links. Two coaxial rollers 30 are mounted on the carriage on a spindle 48 but do not contact the floor 45. Outer guiding and supporting rollers 76, Fig. 2 (not shown), on the spindle 48 contact the floor via wear strips 77. A pair of support rollers 52 are mounted on a spindle 60 at the rear of the carriage. Between the rollers 52, 30 is an inclined ramp portion 50 which forms with the inclined rear surface 61 a T-shaped surface to permit riding thereover of a vehicle wheel. Safety wiper bars 66, 67, Fig. 3 (not shown), extend on each side of the carriage in front of and below the rollers 30, 76. The links supporting the carriages have lateral glides G, Fig. 8 (not shown), to support on guide plates the upper and lower flights 41, 40 of the conveyer chain. The latter is driven from a motor 161, Fig. 10 (not shown), split pulley 159, belt 158, pulley 157, reduction gear 155, coupling 153 and a sprocket 128. A sprocket 42 at the return end of the chain is tensioned by having guides 174 slidable in rails 175, 176 by a nut- and-screw mechanism 182, 180 controlled by a handle 181. At the forward end of the upper flight 41 is a trap-door 35 openable by an approaching carriage 32 and closable by an hydraulic piston and cylinder as described with reference to Fig. 7 (not shown). At the rear end of the upper flight 41 is a trap-door 43 liftable by a carriage as the chain C passes over an idler roller 194.

Anchor pads 20 are thrust against the walls of the tunnel by hydraulic rams 21, 22 and serve as abutments for the thrusting means which are pivoted in spherical seats 25 in the pads 20, the rams being arranged as shown or somewhat modified for details of which Figs. 4, 5 and 6 or Figs. 9, 10 and 11 (not shown) should be referred to. The machine is also provided with rams 50, 51, Fig. 7, operating a roof support 52 and with rams 53, 54 for engaging the tunnel floor. The direction of the machine can be controlled by adjusting the supply of pressure fluid to the rams 50, 53 and to rams acting on pads 19, see also Fig. 14 (not shown), for steering circuit details. The housing 11 carries bearings 58 for the outer cutting head 10 which is concentrically disposed about the inner cutting head 80 and is encircled by dirt buckets 64, see also Figs. 12 and 13 (not shown). The head 10 is driven by a gear ring 65 meshing with three pinions 66 each driven by a motor 17 through gearing 18 and a shaft 67 journalled in bearings 73, 74, 78.
