Patent GB-919633-A (GB)
Title: Machine tool feed mechanism
IPC: B23Q5/34
Filed: 1961-09-29
Abstract: 919,633. Lathe details. CINCINNATI MILLING MACHINE CO. Sept. 29, 1961 [Feb. 6, 1961], No. 35142/61. Class 83 (3). A lathe saddle feed mechanism comprises a drive shaft, a crossfeed gear, and a longitudinal feed gear, selectively connectable to the shaft by a feed control mechanism including a pivotally movable member, and a torque control shaft which moves axially and pivots the movable member to move the feed gears to the neutral position when a resistive torque of a predetermined value is reached. Drive shaft 10 is slidable within the lathe apron 12 and drives a torque control shaft 18 through gears 14, 16. Shaft 18 is rotatably received and axially movable in apron 12 and a worm 20 on the shaft drives a wheel 22 fixed to a shaft 24, which also has a gear 26 fixed thereto. A bracket 28 is pivotally mounted on shaft 24, and carries a cross-feed idler gear 30 and a longitudinal feed-idler gear 32, gear 30 being engageable with a cross-feed pinion 33, and gear 32 being engageable with a longitudinal feed pinion 42 through gears 36, 38 and 40, both gears 30, 32, being in constant engagement with gear 26. The saddle may also be moved longitudinally by a hand wheel which rotates a pinion 41 in engagement with gear 40, thus rotating pinion 42 which co-operates with a rack on the machine. A feed-control bracket 48 connected to bracket 28 by links 54, 58, is pivoted about a shaft 82 by a handle 50 to selectively engage pinion 30 or 32, or to place the drive in the neutral position (as shown in Fig. 2) and is held in these positions by a roller 62 carried by a fork 64 pivotable about a stud 66, which engages a face 74 or 90, or a recess 72, in bracket 48. A member 80 pivotally mounted on shaft 82 is normally held with its peg 84 in engagement with a V-block 86 carried by shaft 18 to hold the latter axially, but when the tool post 15 or saddle 13 encounters a stop, shaft 18 moves axially to pivot member 80 which pivots bracket 48 into the neutral position with pinions 30, 32 disengaged from their respective drives and roller 62 engaging recess 72. Half nuts 106, Fig. 4, actuated by spindle 82, are engageable with a lead screw 108 to provide a screw-cutting feed, and with the half nuts engaged, the longitudinal and cross-feed drives are disengaged and vise versa, a pin 102 on fork 70 which normally engages a slot 103 in a bush 104, being provided for this purpose.

Title: Improvements in or relating to the manufacture of cigarettes
IPC: A24D3/02
Filed: 1931-12-21
Abstract: 394,339. Filter tips for cigarettes. WIX, A., 338, Goswell Road, London, and MAY, R. F., 9, Manor Road, Potters Bar, Middlesex. Dec. 21, 1931, No. 35351. [Class 130.] A cigarette filter tip consists of a strip of material folded from each end to provide the flattened folded portions which are brought together to form a tip of circular cross-section. The length of the strip is such that the middle portion is stretched when the two folded ends are brought together. The ends may be folded in against the same or opposite sides of the strip, the latter arrangement resulting in the folded portions being connected in S-formation. The strip of material is fed transversely to a table 2 carried by a slide 3 reciprocated from a cam 5. Gripping-strips 6, at first kept apart by the engagement of pins 6a with cams 3c on the slide 3, project from a spindle 7 carrying a pinion 7a. The spindle bearings are arranged in arms 8 swung apart against spring action by cams 12. As the arms close the pinions 7a rotate over racks 10 ; the strips 6, which have meanwhile closed on the filter material, roll the latter towards its centre, finishing with a quarter-turn for bringing the folded ends in contact. As the slide 3 recedes a fork 14 rises, and slides the folded tip into the funnel 17. The fork 14 is actuated through a rod 15 from a cam 16. The rack 10 may be flat, convex or concave. The strip may be simply rolled from each end and the folds subsequently flattened before being turned against each other.

Title: Apparatus for the manufacture of filled sweets

Abstract: 1,145,848. Extruding sweets. HAMACHANSELLA A.G. 9 Aug., 1966 [11 Aug., 1965], No. 35526/66. Heading B5A. [Also in Division A2] Apparatus for making filled sweets comprises a container 4, from which filling composition 2 is fed to a pump, which may comprise a cylinder 18 and a reciprocating piston 6, or may be a twin-piston pump. The pump forces the filling composition through a tempering device 24 and a pipe 48, which is connected to a filling pipe 58 surrounded by a ring of conical rollers in a strand-extruder 54, of known type. A sugarcontaining coating composition 56 is fed into the space between the pipe 58 and said ring of conical rollers. The outlet 60 of the pipe 58 is near the output end of the extruder 54, from which emerges a continuous strand of filling composition coated with a jacket of sugar composition. This strand is then divided into sweets. The tempering device 24 preferably comprises a heated cylindrical vessel 26 surrounding a roller 44 having, in its cylindrical surface, spiral grooves 46. The roller 44 is rotated so as to propel filling composition back towards the pump, but a non-return valve 22 is provided to prevent this back-flowing composition from entering the pump. The backflow in the tempering device prevents formation of air bubbles in the filling composition. The vessel 26 may be heated by feeding a heated fluid, such as hot water or steam, through a surrounding jacket space 28. A valve 34 may be provided in the pipe 32 supplying heated fluid to the jacket space. Actuation of the valve 34, and consequentially the temperature of the filling composition in the tempering device 24, may be under the control of a temperature measuring device having a temperature senser 50 in the pipe 48. Stirring blades 62, which are rotatably driven from the shaft of the roller 44, may be provided in the container 4.

Abstract: 772,352. Explosively-actuated appliances for firing projectiles. SCHULZ, W. July 27, 1953 [Jan. 24, 1953 ; June 25, 1953], No. 35650/55. Divided out of 772,351. Class 119. In a firearm or, as shown, a cartridgeoperated tool for firing nails, pins &c. into walls &c. the firing power is varied by forming the cartridge chamber 6, Figs. 1, 3 in a part 6A separate from the barrel 11 the part 6A and the barrel being relatively axially displaceable and formed with mating faces of stepped conical form, the steps increasing in height towards the wider end of the cone and separating in succession when the part 6A and the barrel are moved apart so as to leave an increasing annular space, closed to the outside, into which the explosion gases may expand. The pressure relief space is dependent on the number of steps available between the cooperating faces for expansion of the gases. Fig. 3 shows the position in which the gases can expand into all four of the annular steps and further screwing-out ot the barrel establishes communication with a closed annular chamber 32, in which position the firing power is at a minimum. These variable firing power arrangements may be combined with a recoiling breech block in a tool as described in Specification 772,351.
