Title: Improvements in or relating to Sewing Machines.
Inventor: ANDREWS EDWIN NATHANIEL
IPC: D05B35/08
Filed: 1917-12-03
Abstract: 124,850. Andrews, E. N. Dec. 3, 1917. Sewing-machines; folding-devices; trimming or cutting; work supports.-In sewing-machines for shoe uppers, the edge of the material is guided in an upturned position to an horizontally-acting knife which nicks it, and is then acted on by an horizontally reciprocating finger which folds it preparatory to being stitched. A block 34 is secured to the bed of the machine and carries a pivoted finger 99 adjustable by a spring 98 and stop 97, between which and the curved upper sur face of the block the material is guided. The cutting-device comprises an arm 33 pivoted on the block 34 and provided with a downward pro jection coacting with a sliding knife 39 and strip ping-member 29. A reciprocating shaft 25 carries a pin 30 working in a slot in the knife and in the stripping-member, to which movement is im parted in advance of the knife through a spring 31 to clamp the edge of the material A spring plunger 26 acting eccentrically on the shaft 25 keeps the knife up to the work. The shaft is reciprocated by a link 22 adapted to be engaged by a lever 19 actuated by a cam on a countershaft 17 which is driven fron the looper shaft so as to make one nick for every two stitches. The link 22 is maintained in en gagement with the lever by an arm 42 on a rock shaft 43 under the influence of a spring 44, anc is disengaged therefrom by a spring 23 when the arm 42 is raised. The rock-shaft is acted on by a spring and stop to release the link, and, when turned into operative position, is held by a spring catch. The arm 33 is raised, with the presser foot, by a pin thereon engaging the slot 94. The folding-finger 68 is pivotally mounted on a block 67 sliding in the feed-bar and actuated by a lever driven by a cam on the countershaft 54. The position of the finger is adjusted by a screw 7( and spring 71. The machine is provided with interchangeable cylindrical and flat work-plates to suit the different kinds of work.
Patent GB-704760-A (GB)
Title: Improvements relating to substituted diamines
Inventor: BAXTER RICHARD ALLEN
IPC: C07D213/74
Filed: 1950-07-18
Abstract: A process for the production of an N: N-dialkyl-N1- (2-pyridyl)-ethylenediamine comprises condensing a halogenoethyl-dialkylamine with the crude reaction product obtained by reacting pyridine with an alkali metal amide, this crude reaction product containing an alkali metal derivative of 2-aminopyridine. Substituted pyridines may also be used.  As alkali metal amides are mentioned sodamide and lithium amide.  The initial condensation of the pyridine and alkali metal amide is preferably effected in the presence of dimethylamiline as solvent, and other solvents suitable for a Tschichibabin reaction may be used.  If the halogeno-ethyldialkylamine is used in the form of a salt, a substance to take up the acid, e.g. an alkali metal amide, may be added in the second stage.  The product, in addition to the diamine contains some 2-aminopyridine which may be recovered and converted separately to dialkylpyridyl-ethylenediamine or may be added to a further batch of the initial pyridine reaction mixture.  In an example, pyridine and sodamide are reacted in toluene and dimethylaniline, and to the reaction mass is added a solution of chlorethyldimethylamine and reaction continued.  2-aminopyridine and N: N-dimethyl-N1- (2-pyridyl)-ethylenediamine are recovered.

Filed: 1922-07-03
Abstract: 197,859. Finney, R. G. F., and Fletcher & Co., Ltd., G. July 3, 1922. Roller mills.-In a multiple pair roll precrusher for sugar-cane mills, one of the rolls is driven directly by a tail-bar or the like and the other roll of the same pair and the other rolls of other pairs are in spur-gear connection with it. The cane is fed along a table 1 to a pre-crusher consisting of a number of pairs of rolls 2, 3 and 4, 5 of which the roll 3 is driven by means of a tail-bar 6 and drives the rolls 2, 4 through spur gearing 9, 10 and 12, 13 respectively, the roll 5 being driven from the roll 4 by wheels 15.

Abstract: 146,382. International Time Recording Co., (Assignees of Bryce, J. W.). May 15, 1919, [Convention date]. Compiling and tabulating statistics mechanically. - In machines for electrically registering and sorting perforated statistical cards, the currents for operating the counters when and as the' perforations permit are supplied by a magneto 28 driven by the machine in timed relation so as to produce current impulses only at the necessary instants. The presence of a card in the shoot deflects a lever 7 to close contacts 8, and a closure of contacts 10 by the cam 9 allows current from a source 11 to pass through wire 14 to relay switches 15 and 16. Switch 15 thereupon establishes an alternative circuit to the motor 32 by shunting the starting switch A. Switch 16 closes a circuit at 25 through cam-operated contacts 27 for counting the number of cards and also completes circuit at 24 for the magneto 28 rotated by the machine so as to send the impulses through the cards as they arrive in position between a plate 6 and brushes 4 connected with the counters by leads 2. The magneto shaft may have a cam 30 adapted to raise and lower a contact arm 31 so as to allow only the top of a current wave to pass.

Abstract: 652,903. Photo-electric printing control. MADDICKS, H. T. July 9, 1948, No. 18500. Convention date, July 18, 1947. [Class 40 (iii)] In a contact-printer in which the exposure time is controlled by a photo-cell which receives light passing through the negative and printing paper during printing, the printing paper and negative are held in contact by a light-pervious platen above which the photo-cell is positioned. As shown, the negative and printing paper 7, 8 are positioned on a transparent or translucent screen through which light from a source 2 passes. The light-pervious pressure platen 4 is hinged at 6 and has over it a light-tight box 12 in which the photo-cell 11 is situated. A piece of perforated felt situated under the pressure platen ensures intimate contact between the printing paper and negative. A switch 13 is arranged to break the lamp circuit when the pressure platen is lifted. A number of photocells may be used, or the light may be concentrated on to the cells by a lens, a light guide, or an internally-reflecting hood (Figs. 2, 3, 4, not shown). The pressure platen may itself be of opaque material with a number of perforations but these perforations must coincide with those in the felt. A barrier-layer type cell may replace that shown. It is stated that the platen may be of " checkerboard" construction, in which photo-cells each receive light from adjacent sections of the platen, the outputs of these cells being compared in an electronic bridge circuit, the output of which may be used to influence the control amplifier to modify the colour of the light source, thereby altering the degree of contrast of the print.
