I UNITED STATES CHARLESTON, OF VANCOUVER, BRITISH COLUMBIA, CANADA.

STAMP-OPERATING DEVICE.

Application filed March 27, 1924. Serial No. 702,210.

To all whom it may Concern Be it known that I, MACE E. CHARLESTON, a citizen of'the United States, residing at Vancouver, in the Province of British Columbia and Dominion of Canada, have invented a new and useful Stamp-Operating Device; and I do hereby declare that the following is a full, clear, and exact specification, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention is an attachment for machines, particularly of the photograph printing machine type, which raises the stamping device and inks the numbers, letters, or characters therein each time the machine is operated.

The object of the invention is to provide a means for automatically inking the figures, letters, or characters on the numbering stamp of photograph printing machines.

Another object of the invention is to provide a device for automatically raising and inking numbering stamps as the machine on which the stamp is installed operates.

With these ends in view the invention embodies a movable bracket for supporting a stamp which is constructed of levers pivotally attached to each other, a spring for so holding the levers and stamp in the downward position, a curved arm, which engages a post to raise the stand and levers, and an ink roller for engaging the stamp.

Other features and advantages of the invention will be seen from the following description taken in connection with the drawings, wherein Figure 1 is a view showing the cover of a photograph printing machine with the device in place.

Figure 2 is a view showing the device in the downward position.

Figure 3 is a view showing the device in the upward position.

Figure at is a plan view of the device.

In the drawings I have shown my device as it would be constructed wherein numeral 1 indicates any suitable numbering stamp, numeral 2 an ink roller, and numeral 3 the main or parallel lever.

The stamp 1 may be attached to the bar 8 by placing the bar through a groove 4 in its upper side and holding it by a pin 5. The bar 3 is pivotally attached to double links 6 and 7 and these links are pivotally The spring 11 is arranged so that one end 13 will bear against the upper side of the cover and the other end 1 1 will be placed through a hole 15 in the end 10 of the pin 9 as shown in Figure 1. It will be seen that this spring will tend to twist the pin 9 in a counter-clockwise direction so that it will hold the levers and stamp in the position shown in Figure 2. The opposite end which would be bent to form the projection 12 as shown will engage a vertical bar 16 as the cover moves upward and as it is forced against the bar it will twist to the position shown in Figure 3 and move the stamp and levers upward as shown. As the cover moves downward the spring will move the stamp and levers back to the position shown in Figure 2.

The ink roller 2 is rotatably mounted in a bracket 17 through a pin 18 and the bracket 17 is pivotally mounted on the pin 9 and held so that the ink roller 2 will have a tendency to move upward by the action of a spring 19 on a bolt 20. It will be seen that the tension on this spring may be adjusted by the nut 21. As the stamp 1 moves upward its lower surface will engage the ink roller so that it will pass over it to the position shown in Figure 3. It will be seen that this will be absolutely automatic and will work independent of all other moving parts.

It will be understood that changes may be made in the construction, without departing from the spirit of the invention. One of which changes may be in the type or design of the stamp; another may be in the means for attaching the stamp to the bar; and still another may be in the use of a spring of any other type than that shown.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent, is
