433,643. Workmen's time-recorders. GLEDHILL, A. H., Trinity Works, Halifax, Yorkshire. March 6, 1934, No. 7060. [Class 106 (iv)] In time-recorders for workmen the time type wheels are adapted to record the time in minutes in units and tens, and hundreds and thousands, and the driving mechanism interposed between the clockwork and the type wheels is adapted to be thrown out of engagement for any predetermined periods during the day. The clockwork drives a shaft B, Figs. 1, and 2, to which is secured a block C carrying a pivoted spring controlled latch c<1> that co-operates with a slot d in a disc D loose on the shaft B. The disc D is formed with a boss d<1> and a flange d<2> from which projects a pin d<3> passing through a slot in a gear wheel d<4> and normally held against one end of the slot by a spring d<5>. The movement of the shaft B is transmitted by the disc D and wheel d' to a wheel d' secured to a shaft E rotatably mounted in end plates F, F<1> and to which is fixed a type wheel G representing minutes in units and tens from 0 to 99. A snail cam J, Figs. 2 and 3, on the wheel G co-operates with an arm j pivoted on a pin j<1> and rigidly connected to another arm j<2> carrying a spring controlled pawl j<8> that co-operates with a wheel h to advance the same one unit on the completion of a revolution of the typewheel G. The wheel h is secured to a typewheel H with type representing hundreds and thousands of minutes loose on the shaft E. During this transfer operation a projection j<11> on the pawl engages a pin on an arm j to withdraw a detent pin j from engagement with the teeth of the wheel h and a pin j on the end of the arm j<2> engages the teeth of the wheel to prevent overthrow; the arms j<2> and j<5> are connected by a spring j<7>. Means are provided to disengage the driving mechanism during meal times and other non-working periods. For this purpose a disc K, Fig. 1, driven by the clock to make a revolution once a day is provided with pins k<1> .... k<4> that co-operate with an arm k<5> operatively connected to an arm k<9>. Attached to or formed integrally with the arm k<9> is a second arm k<12> and on these arms are pins k<11>, k<13> adapted to co-operate with a projecting cam surface d<8> on the disc D. The parts are shown in Fig. 1, in the position they occupy at 12 o'clock noon; if it is assumed that the dinner interval commences at 12.30 p.m. the pin k<1> has displaced the levers k<5>, k<9>, and k<12> and the disc D has rotated through 180‹ so that the pin k<13> has ridden up the cam surface d<8> and is then released to knock the latch c<1> out of the slot in the disc D. At the termination of this interval the latch c<1> has made one revolution and as the pin k<1> has freed the lever k<5> the latch under its spring action again engages the slot d. Pins k<2> ... k<4> act in a similar manner to arrest the drive during the hours from 5 a.m. to 8 a.m. so as to reduce the total working period to 2,400 minutes to ensure the typewheels being at zero at the same time each day.
