Abstract: 471,267. Forming chaser &c. teeth. HERBERT, Ltd., A., LLOYD, A. H., and BOOTH, H. April 4, 1936, No. 10006. [Class 60] [Also in Group XXII] The teeth of screw-cutting dies or chasers are formed or trued by a tool 25, which may be a grinding-wheel with a single annular ridge, or more than one ridge on its periphery, or may be a turning-tool, the chasers 8 being held by clamps 11 in slots 13 equally spaced in a carrier 9 with their outer surfaces equidistant from the axis of the carrier. The carrier is slidable on a non-rotating shaft 15 having a flange 16 at one end carrying a lug 17 engaging a V-guide 18 and the shaft is fed axially, to advance the chasers one tooth for each complete revolution thereof, by means usual in lathes &c. Rotatable but not movable axially on the other end of the shaft is a sleeve 19 having a driving notch 27 and a driving and sliding connection 20 with the carrier 9, a spring 21 pressing one end of the carrier. On the shaft 15 is cam means 22 having a single axially projecting incline 23 to be engaged by four equally spaced balls 24 mounted in the carrier and engaging the incline 23 as the chasers come into engagement with the tool 25, so that the chasers are given additional axial feed necessary for cutting the tooth at the correct helical angle. The tool 25 may be fed radially to obtain the required depth of cut, and may be trued before the final cuts are made. The tool is moved towards and from the carrier 9 by an eccentric rotating at four times the speed of the carrier 9, and by appropriately shaping the eccentric, the chaser teeth may be given straight edges as at 34, Fig. 6. For chasers having left-hand threads, the flange 16 guided by the part 18 is separate from the shaft 15, which is rotatable and is driven, the carrier 9 being rotated by the shaft and moved as described above by the cam means, whilst all of the parts also are fed as described above.

Title: Improvements in the manufacture of corrugated paper-board
Inventor: MOSER HENRY WILLIAM
IPC: B31F1/28
Filed: 1961-03-21
Abstract: 907,925. Making double-faced corrugated paper-board. LANGSTON CO., SAMUEL M. March 21, 1961, No. 10210/61. Class 96. A web 11 of single-faced corrugated paper with adhesive applied to the exposed crests of the corrugations is adhered to a facing ply 12 to form double-faced corrugated paper-board by passing the assembly over hot plates 13, e.g. heated by steam chests 64 and holding it in close contact with the plates 13 by a travelling belt 15, the lower run of which is pressed against the travelling paper-board by a series of idler rolls 22, 23, provision being made to raise the belt 15 clear of the hot plates automatically in the event of the travel of the belt being interrupted, as by an hydraulic &c. cylinder 59 &c. and other hydraulic cylinders (not shown) raising rails 27, 26 to move the rollers 22, 23 and the belt roll 17 to the positions illustrated by chain lines, using a series of bell-crank levers 48 spaced along the machine and actuated together by a connecting-rod 49. Initial elevation of the rails 27, 26 does not raise the belt 15 but raises the idler, pressure rolls 22, 23, thus facilitating initially threading-in the double-faced web. Further upward movement of the rails 27, 26 also raises the belt, by means of transverse plates 62. Each of the rolls 22, 23 is on pivoted arms, and the rolls 22 may be loaded or unloaded by individual hydraulic cylinders 24. The rolls 23 rest under gravity on the belt 15. The belt 15 is tensioned by fluid pressure applied through a piston and cylinder, or by an hydraulic torqueactuator applied to two pulleys to urge them against opposite sides of the belt which passes approximately in a Z-shaped course about them. After passing over the hot plates, the paperboard is cooled in the conventional manner. The belt-lift mechanism may be actuated as by disconnection of the main motor drive, or even with the clutch engaged, thus protecting the belt 15 from over-heating, stop-switches and limit-switches being provided.
