Title: Novel wrapping machine
IPC: B65B11/08
Filed: 1924-08-13
Abstract: 242,364. Armstrong, H. Y. Aug. 13, 1924. Packeting by wrapping-up. -Relates to wrap. ping-machines of the type in which the article to be wrapped, in its passage through the machine, withdraws wrapping material from a supply and becomes wrapped in the web. As shown, the article to be wrapped is fed by a plunger 31, Fig. 1, from a support 30 to the receiving end of a vertically swinging transfer element 32, pivoted on a shaft 34 and then in its lower position. A web W is drawn over a reel 68 and a table 69 above the support 30 and is draped in front of the article A as shown in Fig. 17. The transference of the article to the transfer element 32 causes the web to be applied in a partial bottom fold w, Fig. 18, a front fold w<1> and a top fold w<2>. Folding blades 85, Figs. 1 and 2, on the transfer element form end flaps w<3> and upper and lower triangular flaps w<4>, w<5>. During the upward movement of the transfer element to the position shown in Fig. 1 folding blades 86 turn down the upper flaps w<5> to form the top flap w<6>, Fig. 19, and the forward flaps w' thus formed enter oblique slots 87, Fig. 1, in the blades 86 preparatory to being laid flat in the subsequent movement to the right of the article. At the same time the portion w<8> of the web is applied to the rear side of the article, a roller 75 on a swinging arm 76 controlling this operation. The blades 85 are mounted on carriages 102, Fig. 2, by means of sliding stems 114 secured by screws 116 and the carriages are adjustably fixed in slots 120, equalizing arms 118 ensuring equal movement of the blades. The blades are caused to open and close at the required times by face-cams acting on rollers 105 and are normally urged together by the blades 86 which are acted on by a spring 110 and are secured for lateral adjustment in slots 87'. A bifurcated pusher 55, Fig. 1, forces the partiallywrapped article into a runway 45, during which movement the flaps w<7> are turned down to form the flaps w<10>, Fig. 20, the portion w<9> of the web is turned up on to the bottom of the article and the lower triangular flaps w<4>, w<11> are turned up to complete the wrapping by the forward edge 93 of plates 94. When the bottom fold w<9> has been applied, a knife 90, Fig. 1, is uncovered by moving a guard plate 140, a brake bar 73 is depressed to hold the web, and the movement of the article causes the wrapping of the package to be severed from the web. Prior to the brake bar 73 being depressed, the roller 75 has moved to the lower position shown in broken lines in Fig. 1 to draw another supply from the roll. The continued movement of the package carries it past hot-plates 96, in the event of the wrapper being of waxed paper, and into a cooling member 100. The parts 94, 96, 100 are laterally adjustable.

Title: Improvements in or relating to carriage returning mechanism for typewriters
IPC: B41J11/24
Filed: 1936-07-11
Abstract: 464,887. Friction clutches. FAIRWEATHER, W. C. (Underwood Elliott Fisher Co.) July 11, 1936, No. 19286. [Class 80 (ii)] [Also in Group XVI] Carriage-returning mechanism for typewriters comprises a motor and means for causing the motor to return the carriage against a stop, said means including a carriage-starting friction clutch between the carriage and the motor, effective to start the carriage to full speed without yielding of the drive or lagging of the carriage, and arranged to respond automatically to the speed of the carriage, so that the grip yields as the carriage momentum increases above a certain maximum, so that, in result, the carriage is promptly started and brought to maximum momentum by full motor torque, but the said momentum is not exceeded in long carriage runs. The clutch connects a shaft 36, coupled by a universal joint to the motor shaft, and a reduction gear shaft 34, (not shown). The shaft 36 extends part way into the bore of a member 55, and the shaft 34 which is formed with a ball-end enters the bore and abuts the end of the shaft 36. The member 55 carries an outer spherical friction surface 59 with which engage shaped pads 66 carried by centrifugal arms 65 pivoted at 68 to a disc 61 secured to the shaft 34. The surface 59 and the ball-end of the shaft 34 are concentric. The arms 65 are pressed inward by springs 72 whose other ends are retained on lugs 73 on a casing 71. The casing 71 is secured by screws 75 passing through slots 76 into the pivots 68, so that it can be'rotatably adjusted to alter the pressure of the springs 72. When the speed of the carriage increases beyond a maximum determined by the springs 72 the arms 65 move outwards and slip occurs.

Abstract: 1359143 Beverage-making machine ER BRAMAH 22 July 1971 [22 April 1970] 19316/70 Heading A4E Apparatus for making hot coffee or tea comprises a boiler 15 with an overflow 26 for the discharge of heated water to a beverage brewing device (14) Fig.1 (not shown), a supply container 16 with an outlet 30 for the supply of cold water to the boiler 15 and the displacement of hot water from the boiler 15 thereby, and a heater 32 in the boiler 15 and of sufficient capacity to maintain the water in the boiler 15 at least at the desired temperature during inflow of cold water from the container 16. The container 16 is a close sliding fit in the upper part of the boiler 15, resting on supports 20 and constituting a detachable lid for the boiler. The boiler 15 is mounted in a housing (13), Fig.1 (not shown) having a lining 21 of heat-insulating material, such as expanded polyurethane. The lower opening of the outlet 30 is close to the bottom of the boiler 15 so that the flow of water into the boiler 15 may be restricted thereby. The rate of flow of water through the overflow 26 is arranged to be less than that through the outlet 30 by the provision of a restricting spray head 23. A temperature sensor 33 is located in the path of water discharging directly from the outlet 30 or deflected from the bottom of the boiler 15, and a control connected thereto switches the heater 32 on when a predetermined minimum temperature is registered. The heater capacity and the rates of flow are such that the temperature of the water in the boiler 15 may be at least 85‹C for inflow of water at 15‹C from the container 16. A funnel (14), Fig.1 (not shown) containing coffee or tea and a filter paper may be slid into position under the housing (13) along runners 39. A flask is placed under the funnel (14) to receive the beverage. The apparatus may be mounted on a base (11) incorporating an electric hot plate (40) to warm the flask. A second electric hot plate may be mounted on top of a cover 35 for the container 16.

Abstract: 1388994 Manipulators COMMISSARIAT A L'ENERGIE ATOMIQUE 24 April 1973 [10 May 1972] 19361/73 Heading B8H A remote manipulator comprises a forearm 4 having a tong unit 7 articulatedly connected to one end thereof its other end being connected by an elbow pin 3 to a tubular arm 2 which is mounted for rotation about an axis 90 and on which is mounted a block 9 mounting four drive motors (not shown) for controlling the actions of closure of the tong unit 7, rotation of the unit 7 about its own axis, elevation of the unit 7 about a waist pin 6 and rotation of the forearm 4 about its own longitudinal axis, the manipulator comprising three further motors 18, 19, 20, the first of which produces the rotation of the arm 2 about the shoulder axis 90, the second and third motors 19, 20 being mounted as a differential drive system such that if the said two motors are caused to rotate in the same direction and at the same speed, this produces the rotation of a pulley 16 connected by cables 15 to pulleys 13, 14 which produces the angular displacement of the forearm 4 about its elbow axis over a range of travel having the same amplitude and direction as the block 9 which performs a balancing function, while if the motors 19, 20 rotate in opposite directions the arm 2 is caused to rotate about its own axis 64. The motor 18 has a driving pinion 26 mounted on its output shaft which meshes with a toothed ring 27 at the base of a fork 21 in which the arm 2 is transversely mounted, so that when the motor 18 is driven the fork 21 rotates about the axis 90. The motors 19, 20 have respective driving pinions 36, 50 meshing with respective toothed rings 37, 51 at the base of a tubular element 38 and a shaft 52 respectively, said element and shaft 38, 52 being provided with transverse rings 41, 55 respectively each having a peripheral set of bevel teeth 42, 56 which mesh with bevel teeth formed on sleeves 44, 57 which are mounted to rotate freely on the tubular arm 2. The bevel teeth on the sleeves 44, 57 are also in mesh with bevel teeth 47, 59 formed on the pulley 16. When the motors 19, 20 are driven to rotate together at the same speed the sleeves 44, 57 are rotated in the same cyclic direction and thus the pulley 16 is rotated. When the motors 19, 20 are driven at the same speed but in the opposite direction the pulley 16 is locked in position about the axis 17 on account of the opposite forces applied thereto by the sleeves 44, 57 and because the pulley 16 is mounted on a stub shaft 2a which is integral with the arm 2 the pulley 16 and thus the arm 2 are caused, by the sleeves 44, 57, to rotate about the axis 64 of the arm 2, the sleeves 44, 57 travelling about the bevel gear teeth 42, 56 during this motion.
