Patent GB-338990-A (GB)
Abstract: 338,990. Friden, C. M. F. June 23, 1928, [Convention date]. Divided on 314,058. Multiplying &c apparatus; keyboard interlocks.-In a machine for the four rules the movement of the actuator from full cycle position operates, through centralizing levers, means to lock the key latching means in key locking position. As shown in Figs. 1, 2 and 3, applied to a machine with reversible rotary actuators connected to a duplex lever system 21, 22, cooperating in known manner with the key stems the keys 17, Fig. 3, are arranged in rows and each row has a spring pressed slide 26 co-operating with cam projections 28 on the key stems to hold them in depressed position. To hold the depressed keys locked upon the initial movement of the actuators in multiplication and division operations the centralizing levers 122, Fig. 1, which normally hold the actuators in full cycle position, are operatively connected through an extensible coupling 138 to a bar 136 with a projection which is adapted to engage a pin 133 on a locking bar 128 and rock it clockwise, Fig. 3, into a position to engage a tooth 127 on each of the slides 26. The bar 128 has teeth engaging the brackets 24 to prevent longitudinal movement thereof In adding operations the key locking means is disabled by means of a key 142 the stem of which has a pin 145 disposed in a slot in the bar 136 and on depression rocks the bar to move its projection 137 away, from the pin 133. The keyboard may be cleared manually by depressing a clear key 152, a shoulder on the stem of which rocks a lever 148 to push the slides 26 backwardly. During the addition operation the keyboard is cleared automatically by means of a bar 159 mounted on a pin eccentrically mounted on the gear 43. This bar is slotted to receive a pin 162 on the stem of the key 142 so that in its depressed position the end 161 of the bar 159 is moved into position to contact with the lever 148 to displace the slide. To lock the differential setting elements in set position each element is provided with a toothed portion 165, Fig. 3, which cooperates with a holding pawl 166 operated by an arm 168 through a cam 169 secured to the shaft 5. In multiplying operations the lock is maintained, substantially continuously, by means of an arm 174 pivoted on an eccentrically mounted pin 175 on the gear 44 and having a projecting end 173 to engage a pin 172 on a depending arm 171 of one of the pawls. Depression of the key 142 in adding operations causes, through the pin 145, a rocking of a lever 179 and a lowering of the rear end of a lever 177 to disengage the end of the arm 174 from the pin 172 so as to effect an early release of the differential selecting members after the keys have been released.

Title: Improvements in metal barrels and method of and machine for making the same
IPC: B21D51/20
Filed: 1927-12-15
Abstract: 302,054. Wilcox, H. C. Dec. 15, 1927. Hollow-ware.-An open-ended cylindrical metal shell is formed to barrel shape by expanding the centre and reducing the ends without varying the thickness of the metal. The seam-welded shell is placed on the mandrel 13 and the machine started, the first operation being a sliding of the shaft 10 to operate toggle links to move the individual sections 14 of the mandrel radially outwards and so expanding the middle of the shell, the ends of the shell coming towards each other to allow for their bulging. This bulging now acts to hold the shell on to the mandrel. The cam 46 now moves mechanism to withdraw the bolt 35 from its locking position in the cylinder 4 and at the same time the cam 128 operates a hydraulic valve 82, which forces dies 72 in against the shell to smooth it against the mandrel while the mandrel moves outwardly and die 91 moves up with the cylinder to iron the end smooth against the mandrel. The mandrel is also moved outwardly by shaft 10 followed by the die 91 until cam 46 permits a weighted arm to project bolt 35 up to lock the cylinder 4 and at the same time the cam 128 shifts hydraulic valve 82 to exhaust the hydraulic pressure from the radial die cylinder 77 and longitudinal diemoving cylinders 99. This allows springs to retract dies 72 and 91. At this stage the crank shaft moves the shaft 10 back as the cylinder and its mandrel is locked, the toggles 20 are pulled so as to withdraw radially the mandrel section 14 and leave the shell loose on the mandrel. Further movement unlocks the cylinder and moves the mandrel back and so strips the shell of the mandrel. Further movement locks the cylinder again, and the shell is then reversed and placed by hand on the mandrel and the same operation is gone through to form the other end.
