Title: Improvements in and relating to apparatus for applying a wrapper leaf on a cigar bunch
IPC: A24C1/30
Filed: 1963-02-26
Abstract: 1,031,282. Cigar making machines. KONINKLIJKE VEREENIGDE TABAKSINDUSTRIEEN MIGNOT & DE BLOCK N.V. Feb. 26, 1963 [March 1, 1962], No. 7714/63. Heading A2C. Apparatus for applying in one cycle of operation a cigar wrapper leaf to a cigar bunch comprises rollers 6 mounted for reciprocation under a leaf holder and is provided with a movable guide roller 77 and movable guide plate 76 which form a composite guide member. Two suction leaf holders are provided (Figs. 1 and 2, not shown) together with two cutting dies. Leaves are placed on the dies, over which rollers run to cut out wrappers of the desired shape, and the leaf holders oscillate alternately between a position where a wrapper is picked up and a position where the wrapper is to be released for rolling. The rollers 6 are mounted on a support 44 which reciprocates in timed relation with the movement of the leaf holders on bars 46, the rollers being driven from chain driven sprocket wheels 58 and 59. At the end of travel of the support remote from the leaf holder the rollers are opened by a stop mechanism for removal of a finished cigar and insertion of a bunch to be rolled. The guide plate 76 and roller 77 are swung about an axis 78 on arms 80, pivoted on a shaft 79. Movement of the guides if effected by an arm 81 and two-armed lever 86 having cam followers 82 and 88 respectively which run over cam surfaces 83 and 87. A roller 89 for forming a conical end to the cigar is provided on a swingable lever 90 controlled by a two-armed lever 92 by means of a cam follower 93 and cam surface 94. The leaf holders are provided with valve controlled blowing orifices, as well as suction, for progressively releasing the wrapper into the rolling mechanism. In operation, after the bunch has been introduced to the rolling mechanism, movement of the support 44 towards the underside of one of the leaf holders begins. When the support 44 reaches the leaf holder the plate 76 and the roller 77 are swung in and the lead-in flap of the wrapper released from the holder. Shortly afterwards the roller 77 is swung upward slightly so that a toothed wheel 95 thereof engages a rack on the underside of the holder and the roller is thereby driven. A flag portion of the wrapper for forming a conical end is then released from the holder and the pressing roller 89 moved by the cam 94 to its operative position. The plate 76, roller 77 and roller 89 are kept in their operative position as shown by locking their members during the remainder of the wrapping and until the end of the returned stroke. The wrapper is glued during conveyance by the leaf holder from the cutting die to the rolling station.

Filed: 1941-06-20
Abstract: 546,167. Feeding sheets. BISHOP, E. L. June 20, 1941, No. 7769. [Class 100 (i)] Blanks are fed to creasing, folding &c. machines, from a portable device mounted on wheels 26, by means of a suction device 20 mounted in a reciprocating carriage 7, 7a movable over antifriction rolls 7b in rails 5 connected to vertical stanchions 6 fitted with wheels 26. The suction device 20 is adapted to be reciprocated by a lever 8 operated by a cam 10a on the drive-shaft 12 of the feeder which is driven from the associated machine, and the shaft 12 by means of a crank 13 oscillates the piston of a suction pump 15 to reduce the air pressure in the device 20 in order to cause this to grip the forward end of the lowest blank of the pile B. The vacuum in the suction device 20 is produced instantaneously when the piston uncovers a port in the cylinder wall connected by a pipe 21 to the device 20, and the vacuum is broken when the piston reaches a relief port 15a. The blank is drawn through an adjustable gate 22 to prevent double feed, and guides 25 adjacent to the gate direct the separated blanks to feed rolls 18 driven by a belt 17 from the shaft 12, or to other forwarding devices. The oneway valve 23 of the pump 15 may be held open by a lever 24 when it is desired to put the feed out of action, and normally this allows escape of air on the inward stroke of the piston.

Filed: 1966-02-24
Abstract: 1,130,523. Feeding webs. INTERNATIONAL STANDARD ELECTRIC CORP. 24 Feb., 1966 [26 Feb., 1965], No. 8160/66. Heading B6B. A web 5 of thin foil passing from a supply roll 1 to a wind-up roll 4 is smoothed and tensioned by passing it under a smooth surface 3 with suction ducts 6. The surface 3 forms the base of a suction box 8, and by regulating the suction the tension in the web can be adjusted. The two sides of the box are extended downwardly to form side guides (11a 11b, Fig. 2) for the web and additional suction ducts (12a, 12b) are provided adjacent to the guides to keep the web edges flat. To reduce friction, the webengaging surface 3 may have a layer of polytetrafluorethylene. The supply roll 1 may be driven, and the drive may be arranged so that a loop is formed between the roll 1 and the device 3 to facilitate changing of the roll 1. The smoothing of the web facilitates cutting off of the web on completion of a winding on the roll 4, or the joining of a new web to the web being wound on the roll 4, the latter being held stationary during this operation. If a number of webs are being wound on the roll 4 to form a capacitor unit, each web may pass through a separate smoothing device, although in some cases a double web may pass through one smoothing device if the two webs tend to adhere to one another due to, e.g. electrostatic forces.

Title: Improvements in or relating to hollow metal engine parts or valves
IPC: F01L3/14
Filed: 1940-05-07
Abstract: 544,128. Valves. EATON MANUFACTURING CO. May 7,1940, No. 8230. Convention date, May 10, 1939. [Class 7 (vi)] [Also in Group XXII]  A reciprocating hollow metal engine part such as a poppet or other valve of steel &c. which may be charged with sodium &c. for cooling has some copper or other metal, having high thermal conducting properties, cast inside the valve adjacent the hottest part, e.g. the valve seat. A measured amount of copper or other beat conductor is introduced into a hollow valve body 10, which may be produced by boring and swaging a single piece of steel, the valve is heated while being rotated if desired, to melt the copper and, if this is insufficient to fill the valve head, the valve is centrifuged, e.g. by the device shown in Fig. 4, about a vertical or inclined axis. If a low speed, e.g. 150 r.p.m., is used, the copper coating will be spread over the whole inside of the head but if a high speed, e.g. 6300 r.p.m., is used, the copper will be concentrated adjacent the valve seat and will be more fully bonded to the steel. If the copper is sufficient to fill the head, flux or a little alcohol may be added before heating, the valve is not rotated and, after cooling, stem upwards, a central aperture 48, Fig. 5, is bored through the copper. The stem is then swaged down to form the reduced passage 15, unless this has been done before introducing the copper in the case of a valve centrifuged subsequently. After introducing sodium, &c. the passage 15 is closed by a pin 16 and a wear plate 17 welded on. The valve body may have a hard material, e.g. that known under the Registered Trade Mark "Stellite," deposited at the seating surface 19, Fig. 1, and be machined to the desired final form. Specifications 224,288, [Class 7 (vi)], and 511,718 are referred to.
