TIME-CHECKING- MACHINE.

To all whom it may concern:

Be it known that I, THOMAS MONTGOMERY, a subject of the King of Great Britain, residing at Greenock, Renfrewshire, Scotland, have invented certain new and useful Improvement in Time-Checking Machines, of which the following is a specification.

This invention relates to time checking machines for checking the time of workmen and other of the class in which the workinens checks are passed through an aperture and then guided by means of a deflector or chute into boxes, compartments, drawers or other receptacles for the various times, this deflector being moved automatically by mechanism suitably constructed and arranged in connection with and operated from the clock.

The object of the present invention is to provide improved and simplified mechanism for operating the deflector.

The mechanism is so constructed that, at a predetermined time (or times) an arm or equivalent is moved to set the deflector so as to deliver the checks into a certain receptacle and then, by means of a specially constructed cam or snail, the arm is allowed to move back, at quarter hour or other intervals, so as to shift the deflector in such manner as to deliver the checks into late receptacles.

Preferably, in carrying out the invention there is attached to the hour spindle of the clock (which may be of any suitable and well known construction) a pin wheel having holes spaced at hour intervals therein, and a pin or pins can be inserted in one or more of these holes respectively in a manner so as to set the deflector for a predetermined time or times. For instance, two pins may be inserted in the wheel, one to set the de fiector for 6 a. m. and another to set the deflector again for 10 a. m. or three pins may be inserted, one to set the deflector for 6 a. m., one at 10 a. m. and one for 1 p. m.

In order that the invention may be clearly understood I have hereunto appended an explanatory sheet of drawings whereon is shown, by way of illustration or example, one mode of constructing the apparatus. The essential parts of the apparatus only are shown, the other parts of the time checking machine being of a suitable and well known construction.

Figure 1 is an elevation of the deflector Specification of Letters Patent.

operating mechanism with the pin wheel indicated in dotted lines. Fig. 2 is a view of the pin wheel and it connections with the arm h broken ofi. Fig. 3 is a plan view of the mechanism.

A is the plate of the clockwork. B the clock dial indicated in dotted lines. C the boxes, compartments or drawers for the checks. D the deflector, E the hour hand of the clock.

In the arrangement shown, I fit on the hour spindle a a pin Wheel a and this wheel performs one revolution in 12 hours. It has a series of 12 holes I) therein, one for each hour of the day.

0 is the pinion for driving the pin wheel a.

d is the minute spindle and d the minute wheel or cannon pinion which drives, through the wheel 6, the pinion c. On the minute wheel is a snail f which is shown in full lines at Fig. 1 and is dotted at Fig.

This snail along with the minute wheel performs one revolution per hour. On the pin 9 is a sleeve to which an arm h is secured,

the outer end of this arm being connected by means of a link i with the arm j of the deflector D, which latter is pivotally carried on the pin 70 in the usual manner. The checks are inserted by the workmen into the machine through the slot l and drop down as usual on to the deflector. On the sleeve 9 is a second arm m which is a spring arm and has a lateral projection m on it which works on the periphery of the snail The arm it has also a projection h on it with which the pins of the pin wheel engage. The deflector D may be made as usual but has, preferably, a back portion D the function of which will be hereinafter referred to.

I prefer to provide for late periods each representing a i of an hour interval and there may be four or five of such periods. IVith the snail f as shown on the drawings, there are five periods represented by the steps 1, 2, 3, 4, 5. As will be seen, the step 1 overhangs the ste 5, a gap being left between the two. The boxes or compartments O are also numbered 1, 2, 3, 1, 5, corresponding to the steps on the snail.

Assuming it is desired to check the time at 6 oclock in the morning, then a pin n is inserted in the pin wheel at the hole for setting the defiector for 6 oclock and a- 1- hour or other short interval before the clockwork mechanism comes to the 5th hour, 2'. 6. about j; hours before 6 oclock or the time for which it is desired to set the deflector, this pin (41) contacts with the projection il of the arm in and gradually lifts said arm and also the arm m up until, after an hour, 71. about 5; to 6 oclo-ck the arm h will have been raised sufficiently to bring the deflector to the position indicated by full lines at D (Fig. 1) so that checks dropped into the slot Z will be deflected into the drawer or compartment 1, and the arm at will have been raised sufliciently to allow the projection m thereon to rest on the part 1 of the snail. Immediately after 6 oclock the projection m of the arm we will have traveled over the part 1 of the snail and it will then fall on to the step 2 with the result that the arm It will fall into the position it", (Fig. 1) and simultaneously the deflector D will assume the position marked 2*, (as indicated in dotted lines), so that a workman arriving after 6 oclock will have his check deflected into the drawer or compartment No. 2. Nhen a 3 past 6 is reached the projection m will drop again on to the step 3 of the snail with the result that the arm it will assume the position if and the deflector will assume the position indicated in dotted lines at 3 with the result that the time checks will now fall into the box or compartment 3. l/Vhen past 6 is reach the projection m will again drop on to the step 4: of the snail with the result that the arm it will move into the position [a and the deflector will assume the position 43 thereby directing the time checks into the compartment 4. When a g, to 7 oclock is reached the projection 9 will fall on to the step 5 with the result that the arm it will assume the position it and the deflector will assume the position 5*, that is to say, the time checks will new fall on the part D of the deflector and will be directed into the compartment 5. The cleflector will remain in this position so that all workmen arriving at or after a to 7 oclock will have their time checks directed into the compartment 5.

If it is desired to have the apparatus operate at 6 oclock and at 10 oclock then two pins would be inserted in the pin wheel, the one (a) to set the deflector for 6 a. m. in the manner before stated and the other (71 to set the deflector for 10 a. m. The deflector would be in the position indicated at 5 from 7 oclock until say a 3,; to 9 ocloek and when a 21- to 9 oclock arrived the second pin a would again gradually lift up the arm 7 until, after about an hour or to 10 oclock the said arm would be in its topmost position ready for the same movements to be given to the deflector at intervals as occurred at between 6 and 7 oclock. In order to extricate the projection m from the gap between the overhanging part of the step 1 and the step 5 of the snail, the arm at is made of spring metal and the projection m is sli htly beveled so that it will readily disengage.

It will be obvious from the foregoing, that by suitably arranging pins in the pin wheel, the time can be checked for any hour or hours of the day or night.

Instead of using a special pin wheel I may, of course, use the hour wheel of the clock and provide it with a series of holes for pins (1%).

If desired, there may be diflerent snails say one for giving 3,; hour intervals, another for giving i hour intervals combined with shorter intervals, or otherwise, as considered advisable, and these snails would be removably and interchangeably fitted.

One great advantage or the mechanism hereinbefore described is that it can readily be applied to ordinary clockwork mechamsm.
