Title: A safety device for use in connection with machinery
IPC: F16P3/20
Filed: 1942-12-21
Abstract: 561,131. Machinery guards. BAKER, B. Dec. 21, 1942, No. 18095. [Class 80 (iv)] [Also in Group XXII] In a safety device for preventing injury to a machine operator. by relative movement of parts of the machine, a movable machine part such as the tailstock barrel B of a lathe is moved by fluid pressure under control of a solenoid-operated valve, the solenoids being energized by push button switches O and a limit switch p. On depression of the switch O<1> the valve is actuated to move the tailstock centre A on the barrel B towards the work D, the circuit being such that the barrel will only travel in this direction whilst the switch is depressed. When the limit switch p lies in either of the recesses Q, Q<1> in the barrel B it is inoperative but movement of the barrel towards the work causes the switch to ride out of the recess Q<1> and positions it so that if the operator releases the switch O<1>, due to danger of injury, &c., the circuit will be set, to cause the reverse solenoid to be operative and the barrel B to be withdrawn immediately. 'On reaching its forward position the recess Q will render the switch p inoperative and the centre A will be held against the work by the fluid pressure with no current flowing through the solenoids. Depression of the switch O<2> will energize the reverse solenoid and the barrel B will be retracted until the recess Q<1> again breaks the circuit. Since the valve remains in either of its operative positions independently of the energization of the solenoids the fluid pressure will maintain the centre in contact with the work if the electric supply fails.

Filed: 1928-06-28
Abstract: 310,833. Milliken Bros. & Blaw- Knox, Ltd., (Assignees of Dyrssen, W.). May 1, 1928, Convention date]. Regenerators; valves, reversing.-A reversible regenerative system is combined with an air preheater through which part of the waste gases from the checker chambers is passed by an exhausting fan. The preheater can be connected with and disconnected from the system by valves. In the open hearth furnace 1 shown part of the waste gases from the air and gas regenerators 4, 5 passes to the metallic preheater 13 by a pipe 14 and after passing through the preheater is withdrawn through a pipe 15 by a fan 16 and delivered to an aspirator 17 in the flue 10 leading to the stack 18, thus increasing the chimney draught. A fan 20 supplies atmospheric air to the preheater through a pipe 22 and the preheated air passes by a flue 24<1> to the air regenerator 4<1>. Gas is supplied to the gas regenerator 5<1> from a pipe 6<1> and the flow is reversed by valves 7, 7<1>, 9, 9<1>, 12, 12', 25, 25'. When the preheater is not required, e.g. during the refining period, air is supplied to the regenerators through openings governed by mushroom valves 26, 26<1> instead of by the fan 20. A damper 19 in the chimney flue 10 controls the flow of the waste gases, and the exhauster 16 and air supply fan 20 are driven by the same motor 21. Figs. 5 and 6 show the reversing mechanism, the valves 7, 7'; 9, 9<1>; 12, 12<1> being connected by cables 44, 45, 46 to the end of a crank 51 fixed to a shaft 53 rotated by a motor 56. A crank 59 adapted to be clutched to the shaft 53 by a clutch 60 is connected by cables 62, 62<1> to the valves 25, 25<1>. When the preheater 13 is not used the crank 59 is disconnected from the shaft 53 so that the valves 25 are not reversed, and the mushroom valves 26, 26<1> are operated by screw members 68 adapted to raise or lower pulleys 69, 69<1>. In a modification the waste gases are delivered to a waste heat boiler before passing to the stack. The air inlet valves 26, 26<1> may be replaced by a single valve admitting air into the flues 24, 24<1> whence it passes to either regenerator according to the position of the valves 25, 25', which in the modification are operated by the reversing mechanism at all times. The exhauster 16 may discharge the gases direct to the atmosphere. Cold air may be admitted to mix with the preheated air entering the regenerators.

Cash-drawer mechanism.-The releasing means for the cash drawer or drawers of a cash register are operated by connections from the main shaft, and means are provided to disable the connections when a control member is moved to any one of a number of predetermined positions. As shown in Fig. 1, a cash register is provided with a plurality of drawers 55 arranged in a vertical bank and adapted to be selected and released by projections 66 on a vertical shaft 65. The shaft is angularly set by the transmission keys to select a drawer, and is moved vertically by the main shaft 53 to release the drawer selected. The connections between the main shaft and the shaft 65 comprise a cam 110, Fig. 7, driven by the main shaft and engaging one arm 105 of a bell-crank pivoted on a shaft 103. The other arm 106 of the bell-crank co-operates with a notched rod 107, Figs. 5, 7 and 8, slidable in a bearing 108 carried by a pivoted member 100. An arm 99 projecting from the member 100 contacts with an arm 98 on one end of a shaft 93 that at its other end carries a yoke 95, Fig. 1, engaging a horizontal channel 92 in the upper end 85 of the drawer-release shaft 65. The total-taking lever 116, Fig. 5 is connected through link 118, arm 119, pin 120, arm 121, shaft 122, arm 124 and link 125 to the slidable rod 107 which is thereby positioned within its bearing. As shown in Fig. 8, by way of example, notches 126, 127 are provided in the rod so as to register with the arm 106 when the total-taking lever is in its second and third read and reset positions, in which positions the movement of the arm 106 will be idle and no drawer will be released. In a modified construction, Fig. 9, the drawer 13 is released when a pin 12, rotating with the main shaft 16, raises a pawl 7 into engagement with the hook-shaped end 3 of a drawer-locking member 1. The pawl 7 is pivoted to a member 6 that is vertically positioned by a toothed segment 5 integral with a control lever 15. In the lowest position of the control lever, the pawl 7 is positioned above the hook 3 and the action of the pin 12 is consequently ineffective to open the drawer.
