Filed: 1916-10-28
Abstract: 115,443. Thompson, W. P., (Union Special Machine Co.). Oct. 28, 1916. Sewing - machines; feed by dogs; presserfeet; presser-wheels.- A sewing-machine for securing a stay strip to a previously seamed article, such as the sections of a shoe upper, is provided with a device located in advance of the presser-foot to flatten the seam before the strip is attached, thereby avoiding the necessity of the usual subsequent pounding operation, the device being mounted so that it can be swung to one side when not required or to permit the threading of the needles. The invention is described as applied to a machine having two needles 9, 10, Fig. 3, co-operating loopers 23, 24, a presser-foot 17 carried by a presser-bar 16, and a feed-dog 18. The device for flattening the seam is disposed in front of the needles 9, 10 and takes the form of a presser-foot 51, Figs. 3 and 4, carried by a bar 38 journaled in a U- shaped frame 35 mountec. to swing on a pin 34 sbout a bracket 33 supported by the overhanging arm 7 of the machine. A second bar 41 is also journaled in the frame 35, and both bars are surrounded by springs. The bars also pass through the horizontal arms of a second U-shaped frame 44, which is secured to the arms by set-screws 45, 46. This frame carries a lug 49 adapted to engage a notched latch 50 to lock the device in its operative position; a can lever 48 engaging a roller 47 provides means for raising the frame, after which the whole device can be swung to one side about the pin 34. The foot 51 is formed with rearwardly-extending arms in which is journaled a pressure roller 54, and, to support the feed-dog 18 against the thrust of this roller, the dog is extended at 55 and engaged by a roll 56 carried by an arm 57 fixed to a shaft 58, Fig. 6, to which is secured a member 62 having forked arms 61 to embrace a two-part block 60 surrounding an eccentric 59 on the main shaft 14 of the machine. This provides means for maintaining the roll 56 constantly in engagement with the extension 55, and for moving it up and down in time with the feed-dog. Fig. 13 shows in plan view a modified form of the device in which, instead of a single roller 54, there are three spaced rollers 54', 54<11>, 54<111>.

IPC: C12H1/15
Filed: 1954-05-25
Abstract: Grape juices, wines or must under fermentation with or without pulp or skin or fermented must are clarified by adding a pectolytic enzyme complex characterized by being capable of throwing down chlorophyll from aqueous solutions of chlorophyll at a pH of 3.0 to 4.5, a temperature of 25 DEG  to 30 DEG  C. and within a time of up to 40 hours; the juice, must or wine is then left until the main fermentation has been finished and is decanted and centrifuged, or in the case of fermented must or wine for two to four weeks and then decanted, filtered or centrifuged.  The proportion of enzymatic preparation added preferably exceeds 20 grams to each 100 kilograms of juice, must or wine.  Amylase or proteinase may additionally be added.  According to an example, 100 litres of the pulp of crushed purple grapes are treated with 100 grams of an enzyme preparation having the required capacity for precipitating chlorophyll and fermented.  After 6 weeks the iron content in the wine was 8 milligrams per litre as compared with 10 milligrams per litre in an untreated portion; the alcohol contents were 12 and 12.3 per cent respectively.  According to the Provisional Specification, haemin and hematoporphyrin may be employed instead of chlorophyll.

IPC: G09F9/00
Filed: 1931-05-28
Abstract: 385,604. Counting-apparatus. BROCKIES, A. C., 1, Cranston Road, Forest Hill, and GRAHAM & CO., Ltd., A., Caxton House, Tothill Street, both in London. May 28, 1931, Nos. 15695 and 35427. [Class 106 (i).] In apparatus for registering numerical data adapted to pass in either direction through a zero reading the transfer mechanism associated with the drum of lowest denomination may be moved relatively to the drum so as to alter the carry-over position according to whether positive or negative indications are involved. The drums of higher denomination have two sets of markings arranged side by side one or other being displayed through an apertured shutter. As shown in Figs. 1 and 2, a frame comprising fixed plate members and spacing tubes carries a set of indicating drums 4a, 4b, 4c with associated transfer parts and a shutter 5. The lowest or quarters drum 4a is secured to a hub 6a with a driving wheel 7 and pins 24a, 25a extending through quadrant-shaped recesses in a transfer actuating member 8a secured to a partially toothed ring 23a surrounding the hub 6a. The member 8a co-operates with a transfer pinion 9a on a spindle carrying a pinion 10a engaging the toothed gear 11a of the next higher or units drum 4b. A transfer actuating member 8b secured to the hub of the drum 4b co-operates with a similar transfer pinion arrangement to step on the drum 4c. The hub of the drum 4c is provided with a toothed portion 6d which engages a gear 11c carrying a cam 12 coacting with a pin 13a on an arm 13 which arm, through its connection with a lever 14, effects the displacement of the shutter 5. On the hub of the drum 4b a pinion 15 is rigidly mounted and drives two wheels 16, 16a having different numbers of teeth and secured to concentric spindles carrying similar cams 17, 17a, Fig. 4. A spring controlled arm 18 bears on these cams and when their notches are aligned, i.e. when the drums are at zero position, the arm is lowered to place a pin 18a thereon in the path of a member 21 carried by the drum 4a. The member 21, Fig. 6, has a forked end and a toothed portion engaging the part 23a of the transfer member 8a. During the subsequent operation the pin 18a rocks the member 21 from one to the other of its two set positions thereby displacing the transfer member 8a. The transfer member remains in this position until the next passage through the zero reading when the cam notches are again aligned to prepare for the shifting of the member.

Filed: 1973-04-03
Abstract: 1363955 Grinding D G BRAY 3 April 1973 [5 April 1972] 15783/72 Heading B3D A machine for grinding shears, such as garden. shears, large scissors, metal cutting shears and the like, comprises means 22 for holding a blade B to be ground in a generally stationary position, and means for supporting a rotatable grinding wheel 18 so that it can travel over. the blade along a path which follows the curvature of the blade. The machine has a chassis 1 having side walls 1b, 1c on which are secured cylindrical tracks 2a, 2b, the track 2a being inclined downwardly from the rear wall 1d of the chassis to the front, and the track 2b being inclined downwardly from the front to the rear wall 1d, the tracks being slightly curved and the front end of both tracks being at the same height. The tracks are engaged by the wheels 4 of a carriage 3 and a rod 5 extends from the carriage and passes through a universal bearing in the rear wall 1d. A pair of pillars 8 are mounted on the carriage and slidably receive a bush 9 which can be clamped in position by a screw 9a and is secured to a bracket 14 between the arms of which is mounted, with slight tiltable adjustment, a plate 7 carrying an electric motor 16. A shaft 17 of the motor extends through a slot 3b in the carriage 3 and carries the cup-shaped grinding wheel 18 in a guard 19. Movement of the bush 9 along the pillars 8 by a control knob 13 adjusts the peripheral edge 18a heightwise relative to the blade, and the degree of hollow grinding of the blade is determined by the amount of tilt of the plate 7. The blade B is held in a jig 21 having a support 23 provided with a guide 23a for the non-cutting edge of the blade. A clamp 22 grips the blade near its shank and consists of a pair of jaws 22a, 22b in arms 24 which can be moved about pivots 24a by screws 25. The clamp is frictionally mounted on a horizontal spigot and can be tilted from side-to-side by a handle 27, and the spigot is mounted in a block 28 pivotally mounted on a support 28b. The end of the spigot has a slot 29 engaged by a cam 30 on a rod 31 rotatable by a hand lever 32 to effect longitudinal tilting of the blade. The blade can therefore be tilted about longitudinal and transverse noses, and as the carriage moves, the wheel 18 hollow grinds the blades and, because of the inclination of the tracks, follows the longitudinal curvature and the twist or set of the blade.

Abstract: 420,310. Trimming stereotypes. HOWELL, A. H., 211, Queens Road, Wimbledon, London. June 2, 1933, No. 16092. [Class 100 (ii)] The overlay of resilient material employed in the shaving of the backs of curved stereotypes which are formed with printing- areas at different levels to accord with the varying depths of impression desired is retained in the shaving-arch independently of the stereotype so that it can remain in operative position during the shaving of a series of plates. Preferably, suction means is employed, and for this purpose apertures 4, Fig. 2, are formed in the arch and are connected to a pipe 6 in communication with a vacuum apparatus. A valve 9 is hinged to the pipe 6 to enable the system to be opened to the atmosphere when required. A ball valve is provided in each aperture to close the connection to the vacuum apparatus if the aperture is open to the atmosphere within the arch. To facilitate the positioning of the overlay in the arch, a dummy plate 10, Fig. 3, corresponding substantially in form to the plates to be shaved is used, the dummy plate being provided with register marks and with retractible pins 11, 12 to enable the overlay 18 to be correctly positioned. A stop 17 on the plate 10 acts to determine the longitudinal position in the arch. If the lifting-apparatus acts to raise one side of a plate into position first, the plate 10 is provided with a flange 19 covered with resilient material 20 against which the overlay is bent. When this is raised into position, it presses against the flat undersurface 21, Fig. 2, of the arch from which pins 22 project to retain the overlay during the raising of the opposite edge of the plate. To assist this action some of the holes 4 may be located near to the pins 22.
