Title: Improvements in wrapping machines, particularly for the wrapping of so-called mould bread
IPC: B65B25/16
Filed: 1937-12-04
Abstract: 506,769. Wrapping-machines. WESTMAN, K.E. Dec. 4, 1937, No. 33636. [Class 94 (i)] In a machine for wrapping bread, the wrapper 4 is taken from a magazine 5 and manually placed over an opening 3 in the table 2. An article A is placed on the wrapper and is temporarily supported by spring plates 6. Two folding members 8, Fig. 5, flanged at 11, are swung upwards about their axes 12 and apply the wrapper to the ends of the loaf as shown in Fig. 8, the flanges 11 turning the wrapper about the vertical corners. The folders 8 are operated by links 13, 15 and rods 18 mounted in a head 9 vertically slidable on rods 10 and counterweighted at 21. The rods 18 are formed with abutments 22 to allow sufficient motion relative to the head 9 to move the folder between the positions shown. In use, the assembly is raised as shown in full lines, and, on being lowered, the rods 18 move first, causing the folder to move to the position shown in broken lines, to apply the wrapper. In this condition, the whole assembly moves downwards with the article and wrapper, the sides b, Fig. 10, being folded upwards by the spring plates 6. At the bottom of the stroke, the partially wrapped loaf is -deposited in holders 46 on a conveyer 40, adapted to move intermittently to various positions of work. During the first movement, folders 47 pivoted at 48 to the conveyer, are tripped by abutments 51, move forward to apply the flaps c, Fig. 10, to the ends of the article, and are then tripped back by spring action. The flaps d are applied by fixed folders 52, Fig. 4, and the article is stationary at the second working position while another is brought down through the opening 3. Folders 55 mounted on vertical shafts 53, move into the position shown in Fig. 4, to turn down the side flap e, being operated by a cam 61 on the conveyer acting on a segmental rack 57 and pinions 56 on the shafts 53. After passing the peak of the cam 61 the folder is returned by spring action. Plates 63, Fig. 3, next turn down the flaps f, g. The plates are mounted on slides 64 on rods 66 moved horizontally by a lever 73 and guide-head 69. A ramp 68 allows the plate 63 to descend as it moves inwards and to effect the fold with a wiping action, The lever 73 is actuated by a cam 81, Fig. 4, similar to the cam 61. A swinging plate 85; resiliently held in the position shown in Fig. 1, folds down the flap h and the article passes beneath a heat-sealing device 86 and pressing devices 87. The folders 55, 63 are adjustable for height on the shaft 53 and rod 66 respectively. The sprocket wheels 41, 42, and with them the folders 47 and cams 61, 81 are laterally adjustable. The supports 95, Fig. 4, carrying the rods 10, and the mechanism associated with the folders 55, 63 are also laterally adjustable. The folders 47, 55 may be caused to approach the article by axial movement on their shafts 48, 53 during the working stroke.

Abstract: 981,100. Document and like inspection devices. T. ODMANN. Sept. 4, 1962 [Sept. 6, 1961], No. 33919/62. Heading G1A. In a device for testing the authenticity of documents, such as bank-notes, vouchers, and tokens selected parts are examined by photo-electric means to give electrical outputs fed to a comparator. Reflected or transmitted light may be used for the investigation and the comparator may control an automatic sale or exchange machine. In one embodiment a bank-note S is investigated using two sources 1, 2, directing light beams through lenses K to four selected small areas 3, 4, 5 and 6 of the note. Photo-cells A, B, C, and D, view respective ones of these areas and are connected in the circuit shown in Fig. 2. This uses three double triodes T, U, and V with independant anode loads and relays R t , R a , and R V  connected between the anodes of each. The signals from cells A and B are compared by double triode T, from cells B and C by U and from cells C and D by V. Prior to use an authentic note is placed in the test position and the variable cathode resistors G<SP>1</SP> t , G<SP>1</SP> u  and G V 1 adjusted until the double triodes have equal anode potentials and not current flows through the relays. If, in a subsequent test one or more of the relays operates to close the circuit between terminals J this is an indication that the note under inspection differes from an authentic note. Simpler arrangements using three or only two examination areas are described with reference to Figs. 3, 4, and 5 (all not shown). In these the photo-sensitive devices may be photo-resistors forming the arms of a bridge network.

Title: An improved machine for hobbing the teeth of gear wheels
Inventor: GARNER PERCY
IPC: B23F23/12
Filed: 1954-11-25
Abstract: 789,081. Gear-cutting. BROWN MACHINE TOOLS, Ltd., D. Feb. 27, 1956 [Nov. 25, 1954], No. 34142/54. Class 83 (3). A gear-hobbing-machine comprises a bed 1 carrying work-driving-means, and a hob 13 angularly adjustable on a slide 9 movable on the face of a cradle 8, the cradle being angularlyadjustable on a head 7 movable to-and-from the work. The hob is rotated through changegearing by a reversible main motor in the machine-bed, which also rotates two oppositelyrotating bevel gears 45, 46, which rotate a faceplate 5 in one or other direction according to the setting of a clutch-lever 48, through changegears 49-52. The slide 9 is traversed by an hydraulic-piston 62, movement of the slide causing a rack to rotate a pinion connected to two adjustable cam-discs, one of which operates a switch 70 to reverse the slide-movement when cutting is complete, and the other operates a switch 71 to stop the slide in its initial position. The head 7 is adjusted to-and-from the work by a screw. The hob is fed into the work at the beginning of a cut by a piston 78 to which the screw is attached, the stroke of the piston being determined by adjustment during setting-up according to a depth-of-cut dial 87. In operation, a valve-lever 151 is moved manually to clamp the work against the face-plate 5 by a ram 97, and to extend a tailstock 6 by a ram 99, the valve returning automatically to neutral when clamping is complete. A button is then pressed to start the main motor and to operate a valve 103 causing the piston 78 to advance the head 7 to cutting-position at a rate determined by a valve 107. Pressure then builds up to operate hydraulic means 90 to clamp the head to the bed. After a time delay, the piston 62 is actuated to traverse the hob along the work at a speed determined by a valve 115. When hobbing is complete the switch 70 is operated to actuate the valve 103, causing the clamps 90 to be released and the head 7 to be withdrawn. In its rearward position, the head actuates a switch 119 to stop the main motor. Pressure build-up then causes a valve 117 to pass fluid to the piston 62 and return the hob-slide 9. Finally, the valve 94 is actuated manually to release the work. If the valve 94 is accidentally operated during cutting, a switch 121 stops the machine. To ensure even wear of the hob, the hob is carried on a slide 123 which is movable by small increments between cuts, and is clamped during cutting by hydraulic-means. To advance the slide, a rotary member is oscillated by surges of pressure each time the valve 94 is actuated. The oscillation in one or other direction drives, through a reversible roller-clutch, a nut engaging a screw which moves the slide 123. At the limit of the slide-travel, a switch is actuated to illuminate a warning-light and prevent further operation of the machine.
