Title: Improved Machine for Corrugating and Plaiting Webs of Paper and like Materials.
Inventor: MACKENZIE JOHN WILLIAM
Filed: 1903-09-22
Granted: 1904-08-11
Abstract: 20,426. Mackenzie, J. W., [Allen, W. L.]. Sept. 22. Pleating.-Relates to a continuous machine for longitudinally corrugating and pleating webs of paper and like material, the resulting springy pleated material being applicable for bottle wrappers, stair pads, partitions for egg cases, &c. The paper is drawn from a roll and passes over a straight-edged guide - board g, Figs. 1 and 3, which gradually assumes a semicircular form. The web takes up this form, and is delivered between the ends of a series of fixed rods h and a series of belts i, preferably made of spiral springs, and travelling round " score " or grooved pulleys on the shafts c, k and under flexible shafts n, n', n<2>. The rods h are bent so that they lie in a semicircle at one end, and are drawn together and lie in a straight line at the other end, where they are bent up and attached to a plate h<1>. As the web is carried along by the belts i, which pass between the rods h, it becomes corrugated, the depth of the corrugations gradually, increasing, and, after passing clear of the rods h, the corrugations are directed by rods p<1>, Fig. 17, forming extensions of the rods hand projecting between a roll e and score pulleys k<1> on the shaft k. The ends of the rods p<2> are flattened to flatten out the corrugations, as shown in Fig. 21, before the web passes between the pressing-rollers e<1>, e<5>, by which the corrugations are pressed into pleats as shown in Fig. 22. After pressing, the pleats spring back to the form shown in Fig. 23. The upper rolls e, e<1> are driven by spur-wheels from the shaft k and the roll e<5> respectively, these rolls being driven by sprocket-wheels and a chain d' from the main shaft b, which also drives, by sprocket-wheels and a chain d, the shaft c. The pressing-rolls e', e<5> carry knives q<1>, q which cut off lengths of the pleated paper, and projections q<3> on the roll e<5> act in conjunction with grooves q<2> on the roll e<1> to squeeze the cut ends and reduce the tendency of the pleats to flatten out. The rods h are suspended in position by links or eyes from wire coils h<2>, h<4> mounted on semicircular rods surrounding the rods h and fixed to side-plates m<2>, the links being connected to the upper part of the rods only, so as not to obstruct the passage of the web of paper. By this arrangement, the depth of the corrugations produced may be varied by contracting or expanding the coils h<2>, h<4> so as to move the rods h nearer together or further apart. The score pulleys m<4>, Fig. 3, on the flexible shafts n, n<1>, n' serve to guide the belts i and ensure their carrying the web along, and the shafts are mounted in stands secured to the plates m<2> and driven by sprocket-wheels and a chain d' from a vertical spindle o<1> driven by bevel gearing from the shaft c. Fingers i', Fig. 17, fixed to a bar p<4> retain the paper in its corrugated form as it passes from the belts i to the pressing-rolls, and rods p<3> at each side of the machine serve as guides.

Abstract: 24,631. Fouraeau, E. F. A. Nov. 12. Medicinal preparations.-Amido-alcohols of the type : which are useful, along with their derivatives, in medicine &c., are produced by the action of fatty amines upon halohydrins, or of organomagnesium halides upon amidoketones. Thus, ethyl dimethyl amidobutanol, (C2H5)2 : C(OH). CH2N : (CH3)2, is obtained by digesting the corresponding chlorhydrin with dimethylamine, extracting with dilute hydrochloric acid, washing with benzene, saturating with soda, extracting with ether and, after evaporating off the ether, distilling in vacuo. It boils at 76‹-79‹ C. under 23 mm. pressure. Phenyl diethyl amidopropanol results from the action of diethylamido-acetophenone upon methyl magnesium bromide, with subsequent treatment with ice and dilute hydrochloric acid and saturation with soda &c. as before ; its boiling point is 147‹-149‹ C. under 24 mm. All the bases are more soluble in cold water than hot,reduce acid. potassium permanganate solution and silver salts, and yield characteristic esters with acidyl chlorides such as benzoyl, acetyl, cinnamyl, and valeryl chlorides, or with acid anhydrides upon subsequent treatment with alkali.
