Abstract: 668,907. Road-making machine. JAEGER MACHINE CO. March 27, 1950 [April 2, 1949], No. 7604/50. Class 107 A road-making machine has a material laying and spreading unit embodying hopper 4 and spreader 8 and a screeding and levelling unit embodying centre screed 31 and side (or rear) screeds 80. Runners 23 ride over the surface to be covered and carry a frame the front edge of which is pivoted to the runners at their centre of gravity, and the rear edge of which is connected to the laying and spreading unit for free vertical movement. Thus the centre of gravity of the runners tends to remain on a level course, the runners averaging out the inequalities of the ground over their length. The rear screeds 80 are controlled in height hydraulically and the control valves 86 for this height adjustment are operated by an arm 88 carried by two control pans 95, 96 each of which rests on the finished surface left by the front (centre) screed 31, and thus screeds 80 are always kept at the same height as the centre screed 31. Material is bled back from screed 31 and impelled to the rear by screws 118 to supply screeds 80. This bleed off can be regulated or stopped entirely. Material placed in the hopper is conveyed to the spreader by conveyers. The machine is self-propelled by crawlers 4 and engine 3. All the screeds are reciprocated and may be heated, and the whole assemblage contacting the ground may be lifted by hydraulic rams, only the rear ones. 81 being illustrated. All power drives are independent and the screeds can be adjusted to make up a surface of any width within the capacity of the machine. All parts of the machine are described and illustrated very fully. Specifications 439,223, 627,434 and U.S.A. Specification 2,054,436 are referred to.

Abstract: 897,171. Carton blanks; carton folding machines. BIRMINGHAM BOX CO. Ltd. June 6, 1958 [March 9, 1957], No. 7864/57. Class 18. A carton blank having side and end flaps 4, 3 respectively folded up from a base 2 has extensions 5, 6 on the flaps 4, the extension 5 having adhesive 25 which secures the extension 5 to the flap 3. A crease between the flap 4 and the extensions is interrupted to ensure that the blank will fold about a creased and scored line 4a when the extensions are engaged by a member on the folding machine. The blank is erected on an in-line glueing and folding machine in which the blank is held between upper and lower conveyer belts 11, 10 respectively. The nose 13 of a plate 12 deflects the flap 3 and extension 6 out of the plane of the blank and the extension 5 passes beneath a part 14 of the plate 12 and beneath an arm 15 and over a glue wheel 17. An arm 19 prevents deflection of the base adjacent the extension 5. The blank then passes beneath a plate 20 (Fig. 5) which deflects the flap 3 downwards and the inclined end 24 of a spike 22 engages and folds the extensions 5, 6 and part of the flap 4 about the line 4a. Continued movement under the spike 22 folds the flaps 5, 6 and part of the flap 4 on to the base. The opposite side of the blank is simultaneously folded by similar mechanism, and finally the flaps 3 are folded over and pressed on to the adhesive 25. If desired the folding means on one side of the machine may be in advance of the folding means on the other side of the machine so that the extension on one side flap is folded flat on to the body of the blank before any operation is performed on the extension on the other end of the same flap.
