Title: An improvement in paper bag manufacturing machines
IPC: B31B37/00
Filed: 1950-03-23
Abstract: 671,749. Making paper bags. ANDERSSON, N. March 23, 1950 [March 31, 1949], No. 7346/50. Class 94(ii) In making paper bags provided with bellows side folds and a flat folded bottom, from a web which is guided and glued to form a flat tube with bellows side folds and then cut into blanks which are fed to a revolving drum and retained thereon while the bottoms are folded, the bottom-folding operation is prepared by moving the side walls of a flat tubular blank away from one another by two pairs of movable grasping fingers 9, 10, Fig. 2, mounted respectively on the revolving drum 6 and on an adjacent rotating member 7 co-operating with the drum, these grasping fingers being controlled to have a circling movement in a closed path circumscribing a surface extending radially as well as axially with respect to the revolving drum and the co-operating member 7. The bellows side folds are thus straightened out at the parts where the bottom fold is to be made, whereupon the grasping fingers release the blank, and folding means 11 mounted adjacent to the drum operate to complete the first folding of the bottom. During the continued rotation of the drum the bottom of the bag is completed by pasting and closing devices, and the finished bag is removed at 12 on to a conveyer or the like. Any known means are employed for forming a web into a flattened tube 2 which is severed transversely into bag lengths by cutting-rollers 3 and provided with longitudinal folding-lines by rollers 4, and then fed by rollers 5 to the drum 6. The drum 6 and the member 7 rotate in opposite directions, and the feeding-rollers 5 rotate at greater speed than the drum, feeding the blanks forwardly in succession so that each is retained under one of several catches 8 mounted on the periphery of the drum and thus rotated with the drum until the bottom fold is completed, whereupon the catches 8 are operated to release the finished bags, which drop on to the conveyer. Fig. 2 shows a portion of the drum 6, with the grasping fingers 9, 10 just moved into the bellows side folds preparatory to opening out the grasped portions of both sides of the bag. The fingers 9, located one at each side 13 and 14 of the drum 6, are each mounted on an arm 36 which is pivoted intermediate its ends on an arm 15, the arm 15, in turn, being pivoted on a lug 16 fixed on the end wall 13 or 14. The other end of the arm 15 carries a roller 17 which co-operates with a fixed cam bar 18, while at the same time a roller 19 mounted on the arm 36 engages a cam bar 20 on the adjacent side 39 of the machine frame, these actions combining to bring the finger 9 into its operative position. Similarly, the grasping finger 10, carried by an arm 37 which is pivoted on an arm 23 pivoted on the side of the rotary member 7, is controlled by roller and cambar combinations 26, 27 and 24, 25, the arm 37 being bifurcated at its pivoted end in order to straddle the shaft 40 supporting the member 7.

A recording device 203 may then be switched into the line to record a spoken message from the substation. The substation is initially dialled by an operator, using a telephone set D, having first depressed switches K1. When he hears ringing tone he depresses switches K2 and the sequence outlined above then takes place. Lights L1-6 indicate to the operator the current state of the sequence, e.g. recording, playing back, awaiting reply. By employing additional circuitry, Fig. 2 (not shown) a single tape machine may be used to relay a message to a plurality of lines and corresponding substations simultaneously. The substations are dialled in sequence, so each one "comes in" at a different point of the pre-recorded tape.

Abstract: 225,763. Cachemaille, A. S., (Westing- house Lamp Co.). March 29,1924. Coating processes ; paints. - Siliceous or vitreous articles such as electric light bulbs are given an, insoluble coating by applying a preparation containing a soluble silicate, heating and applying a neutral fixing solution of an ammonium salt which reacts with the preparation to form an insoluble compound. The preparation may comprise Kaolin, pigments and sodium 'or potassium silicate, which may be applied by spraying or dipping. The article is heated to 150‹ C. for about two minutes and then preferably dipped into a hot (75-115‹ C.) saturated solution of an ammonium chloride or sulphate, whereby silica is precipitated. The article is finally washed and dried. Instead of applying the fixing solution, hot it may be applied cold, and the article subsequently reheated.

Abstract: 859,757. Railway stops. HUMPHREYS & GLASGOW Ltd. March 13, 1959 [March 13, 1958], No. 8142/58. Class 104 (2). In a device for checking and stopping rail vehicles, a raking dashpot 11 resists movement of a striker 13 engageable, when in the catch position, by a dummy axle 10 provided on a vehicle to be stopped, a releasable stop 16 prevents further movement of the striker 13 when the vehicle is to be stopped and a pneumatic or hydraulic ram 21, 22 releases the striker 13, to permit further movement of the striker 13 beyond the stop position to a release position clear of the dummy axle 10, and returns the striker 13 to a catch position and resets the stop 16. The apparatus operates in the following manner. The striker arms 13, arranged one on each end of a spindle 12 of a rotary dashpot 11, are initially arranged in the position in which they are engaged by a dummy axle 10 of a vehicle at the position shown in chain-dotted lines in Fig. 1. The dummy axle 10 on engaging the striker arm 13 rotates the striker arms 13, against the hydraulic resistance of the dashpot 11, to the position shown in full lines in Fig. I in which position tails 15 of the striker arms 13 engage stops 16 to prevent further rotation of the striker arms 13 and to stop the vehicle. The stops 16 are in the form of bell-crank levers and at one side of the apparatus one lever is connected by lever 18 to a bifurcated lever 19 pivoted at 20 and embracing a pneumatic or hydraulic cylinder 21, the piston-rod 22 of which is connected to the striker arms 13. To rotate the striker arm 13 to a position in which it is out of engagement with the dummy axle 10, Fig. 4 (not shown), to enable the vehicle to pass along the track, pressure oil or air is admitted to the left-hand side of the cylinder 21 and the stops 16 are rotated to a position in which they abut a bracket 25, thus allowing the striker arm 13 to be rotated freely or with the aid of the dashpot 11. To reset the apparatus, pressure oil or air is admitted to the other end of the cylinder 21 to rotate the lever 19 until it engages a bracket 24, thereby resetting the stops 16 and rotating the striker arm 13 to its initial position in which it will be engaged by the dummy axle 10 at the chain-dotted position shown in Fig. 1. Specification 859,756 is referred to.

Abstract: 548,765. Sewage distributers. TUKE & BELL, Ltd., and GLOVER, E. M. [Representative of GLOVER, J. B.] June 30, 1941, No. 8196. [Class 69 (iii)] A sewage reservoir or dosing tank 4 is mounted on a chamber 5 adapted to rotate on a standard A at the centre of a filter bed; the chamber carries radially extending distributer arms 11 and has extensions 5d, 5e projecting into the tank 4. The extension 5d enters a dome 13, and the extension 5e projects above the top level to which the liquid periodically rises in the tank, and each extension has a syphonic device associated therewith which, together with the dome 13, coact automatically to effect a periodic discharge of a dose of the liquid from the tank to the arms 11. One syphonic device 14 has limbs 14a, 14b, and the other device 15 has limbs 15a, 15b arranged as shown, and a liquid seal 15c is located at the end of the limb 15b. When liquid fed to the tank 4 rises above a cut-away part 13a of the dome, and reaches a level sufficient to close the lower end of the limb 14b, a liquid seal is created, and is maintained until the liquid reaches the top level at which the apparatus is designed to discharge a dose of liquid to the arms 11. The pressure within the dome is then sufficient to " blow " the liquid seal 15c, and the liquid in the tank is discharged into the chamber 5 and arms 11 until the liquid reaches a bottom level in the tank when air is drawn into the dome.
