Title: Doubling machine
IPC: B21B47/02
Filed: 1953-04-20
Abstract: 728,103. Doubling sheets. AVESTA JERNVERKS AKTIEBOLAG. April 20, 1953 [April 21, 1952], No. 10814/53. Class 83 (4). A machine for doubling sheets, or stacks of two or more sheets, of metal or other material comprising a table having a transversely extending recess, a bending knife movable up and down in said recess, and a pair of jaws arranged in the recess and adapted to clamp together a sheet partly doubled by the bending knife, is characterized in that the jaws are arranged to clamp together the partly doubled sheet, or pack of sheets, in the recess a short distance from the fold so that a closed fold, loop-shaped in cross-section, is formed. A pack 56 of two, for example, metal sheets are placed on a machine table 14, 15, over a wedge-shaped recess 13, with one longitudinal edge abutting adjustable pins 58, 59 and one short edge abutting a pin 67. Pins 61, 62 on piston rods 65, 66 are then moved in to engage the other longitudinal edge to press the sheets against the pins 58, 59. The length of the sheets, reckoned from the pin 67, is then read off from a scale 69, Fig. 2, and the sheets moved until their edge comes to a line on a scale 70 having a similar reading. The sheets are now exactly positioned over the recess 13. A bending knife 25, slidable on vertical guides 27, is then pulled down, by ropes 30 winding around drums 33 driven by a motor 37, to press the sheets down into the recess 13 forming a round open fold, Fig. 4. As the bending knife 25 reaches its lowest position an abutment 74 thereon engages a limit switch 76 to reverse the motor 37 to cause the knife to rise until an upper limit switch 73 is engaged to stop the motor. A movable side 17 of the recess 13 pivoted about a horizontal axis 19 is then moved towards a fixed side 16 of the recess by fluid pressure means 50. Detachably secured in horizontal channels 43, 48 in the lower parts of the sides 16, 17 respectively are bars 44, 47 formed with ridges 45, 46. These ridges press the sheets together just above the fold to form a final fold 57, Fig. 7, of loop cross-section.

Patent GB-258513-A (GB)
IPC: G07G1/01
Filed: 1926-04-30
Abstract: 258,513. National Cash Register Co., (Assignees of Pein, E. J. von.). Feb. 10, 1926, [Convention date]. Cash registers ; printing totals ; zeroizing mechanism.-In a machine of the key set and operated type the totalizer consists of reading and printing wheels and after a total has been printed from it it must be zeroized before itementering can be resumed. The number of zeroizing operations is registered by means of a reading and printing counter from which the total is printed simultaneously with the taking of the amount total. The totalizer and resetting counter are normally covered by a lid which, when raised for total reading or printing purposes, prevents any operation of the machine or the resetting of the totalizer. The totalizer 55 and the resetting-counter 122 are mounted on the same shaft and between them is a type block for printing the number of the machine. Impression is made by manual depression of a platen frame 166 pivoted at 167 and adapted to force a slip, inserted in a fixed frame 175, against the type formed on the wheels 155, 156. The counters may be read through a window 203 but are normally concealed by a hinged lid 204. When this is raised, it draws upwardly a pitman 205, Fig. 7, to free a pin 213 on a spring-controlled lever 208 pivoted at 207. This lever thereupon turns clockwise to lock the main operating shaft 41 through the medium of the ratchet wheel 217, and also through a fork and pin connection 209 to rock a shaft 211 carrying arms 212, Fig. 9. so that these engage ratchet wheels 63 geared with the totalizer shaft 57 to prevent any resetting movement. When the platen frame 166 is depressed to take a record, an extension 171 rocks a locking lever 191, Fig. 4, so as to place its end 196 above a bracket 197 on the coupler 33 and thus prevent operation of the machine. The lever is maintained in this position by a justifying pawl 195 until subsequent rotation of shaft 64 by the zeroizing operation restores the lever by means of a cam 198 and pin 199. The resetting-key 90, Fig. 3, is inserted in a slotted sleeve 91 geared with a spindle 98 which is in turn geared with the totalizer shaft 57 by means of elliptical pinions (see Fig. 11) to slow up this shaft towards the end of its rotation to prevent overthrow. The geneva transfer wheels for the higher orders of the totalizer are supported by a frame 106, Fig. 14, pivoted at 108 and carrying a bar 112. When the shaft 57 is rotated for zeroizing, shaft 64 is rotated and through a notched disc 102 and lever 104 rocks the frame 106 to raise the geneva transfer wheels out of gear and by means of bar 112 to rock and hold the transfer pawls 71, Fig. 9, out of position. A pawl 107 is also raised into the path of a pin 103 to terminate the rotation by the key. The resetting counter is operated from shaft 64 through a geneva drive.

Abstract: 624,496. Lever clips. LOSCHIAVO, J. April 30, 1947, No. 11638. Convention date, Jan. 28. [Class 44] [Also in Group VII] An ear clip or brooch fastening comprises a U-shaped member and a cam-action clamping member consisting of a length of wire bent centrally upon itself and formed at its free ends with eyes or the like by which it is pivoted to the upper end of one of the limbs of the U, so that part of, the U lies between parts of the cam member and prevents the latter from moving beyond the full clamping position. The wire cam member has an eye 10 at each end and is bent centrally on itself at 11 ; the doubled wire is then bent at 12 and 13 to resemble the numeral 7. The U-shaped member 14, also bent from wire has an ornament secured to one end 18 and is provided with an eye 15 at the other end, which is held between the two eyes 10 of the cam by a rivet or a link 17 passing through all three eyes ; the bend 12 now lies between the limbs of the U, and the bend 11 lies outside the limb to which said cam is pivoted so that this limb acts as a stop to prevent the cam from moving beyond the full clamping position. According to the direction in which the cam is moved it will either clamp an object, e.g. an ear lobe, between itself and the opposite limb of the U, or will release the object. Small niches or indentations are formed on those surfaces of the cam which contact the U when the former is fully closed, so that a click is heard when the cam is home.
