UNITED STATES PATENT INK PAD.

Application filed December 29, 1924. Serial No. 758,527.

To all whom t may concern Be it known that I, CARL E. LIEN, a citizen of the United States, residing at Summit, in the county of Roberts and State of South Dakota, have invented certain new and useful Improvements in Ink Pads, of which the following is a speciiication.

My invention relates to inking devices, particularly of the kind used to ink rubber stamps before printing or stamping with them and the object is to provide an ink pad that will not only have its top surface moistened with ink but is also provided with an ink reservoir from which the pad is automatically moistened for long periods by capillary attraction by the use of wicks as will presentlybe further described.

In the accompanying drawing;

Fig. l is a top view of the improved inking device with its hinged cover raised to a slightly backward leaning position.

Fig. 2 is a top view of the device with the cover and ink pad removed, whereby the top of the ink magazine is clearly exposed.

F ig. 3 is a section on the line 3 3 in Fig. 1 with the cover closed.

Fig. 4 isan enlarged transverse section on the line 4 4 in Fig. 1 wit-li the cover closed.

Fig. 5 is a top view of a modified form of the device with the cover omitted.

Fig. 6 is al transverse section on the line 6 6 in Fig. 5. y

Referring to the drawing by reference numerals, 10 designates a vessel forming the main frame or body of the device and having` walls 11, a bottom 12 and a top plate 13 spaced above the bottom and secured to the wal-ls by solder 14 or other suitable means. In this way an ink magazine 15 is provided and into which ink may be poured through a filler tube 16 having a plug 17.

The frame is preferably provided with the usual cover 18, hinged at 19 to prevent evaporation of the ink from the ink pad proper and which will now be described in some of its modified forms.

The pad supporting plate or magazine top 13 has several slots 20 which are formed by cutting and striking the metal downward to form vertical ribs 21 by which the plate is stiffened so as to better stand the pressure of rubber stamps upon the pad it supports.

When the device is a large one the plate may be further stitfened by longitudinal ribs 22 and even transverse ribs 23 on its under side as shown in Fig. 4. In said view is also indicated that a. thin slotted board 24 may be placed upon the plate, while in Fig. 6 such board is omitted.

In either case the inking pad proper is formed of suitable felt or similar material 25 placed upon the top of the magazine and given extensions or leaders 26 down through the slots into the ink supply (not shown) in the magazine 15. lThe pad thus formed of one or more pieces of material has its top covered with a thin, smooth canvas 27 or other suitable material the top of which is easy to clean and presents a. proper surface for the rubber stamps to be pressed o-n and receive ink from it and the underlying pad, the latter being previously charged with ink and steadily kept suitably moist from the magazine by capillary attraction in the pad and its depending leaders 26, which latter may be integral with the pads or simply arranged in close contact therewith.

The thin canvas may have its edges retained by tacks 2S driven into the wood 24, as in Fig. 4, or where no wood is used the canvas 27 may be secured by strips 29 (Fig. 5 and Fig. 6) and screws 30 passed through them and threaded into the plate 13.

When the ink in the magazine is nearly exhausted it will help some to invert the device for a short time to let the weight of the ink aid in moving it toward the pad, and when that remedy will no longer suiiice the plug- 17 should be removed and the magazine refilled.

What I claim is:

1. In an inking devicel of the class described, an ink magazine or holder having its to-p provided with slots, an inking pad supported upon said top, and leaders extending fiom the pad, down through the slots and into the magazine for drawing ink therefrom into the pad, said pad support beingof sheet metal with ribs at the under sidel to stiften it.

2. The structure specified in claim 1 in which the stiii'ening ribs are formed of the metal struck out of the slots in the sheet metal.

In testimony whereof I atfix my signature.

CARL E. LIEN.
