Application April 6, 1951, Serial No. 219,725
1 Claim. 1
The present invention relates to a self-inking rubber stamp pad and it consists in the combinations, constructions and arrangements of parts herein described and claimed.
Generally there is provided a self-inking stamp pad comprising a body in which is mounted the pad construction and beneath the pad construction a normally closed valve. The body is provided with a raised portion in which is positioned a reservoir which is connected by a channel to the valve structure. Depression of the stamp pad structure causes an opening of the valve temporarily to allow a flow of ink thereto so that the stamp pad is at all times kept moistened with ink.
It is accordingly an object of the invention to provide a stamp pad having automatic means for reinking the same.
Another object of the invention is to provide a device of the character set forth having a novel valve forming a part of the invention.
A further object of the invention is the provision of a device of the character set forth which is simple in construction, inexpensive to manufacture, easy to fill and yet effective and efficient in use.
Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawing, in which:
Figure 1 is a side elevational view of a cover forming a part of the invention,
Figure 2 is a side elevationa1 view of a stamp pad forming a part of the invention,
Figure 3 is a backing plate forming a part of the invention,
Figure 4 is a side elevatlonal view of a secondary inking pad forming a part of the invention, and
Figure 5 is a vertical sectional view of an embodiment of the invention shown in assembled condition.
Referring more particularly to the drawing, there is shown therein a self-inking rubber stamp pad comprising. a body ll} having a recess II in the top thereof and having a raised portion |'2 at one end thereof. Extending from the bottom and communicating with the recess H is a passageway l3 wherein is removably mounted a valve structure generally indicated at I l.
The valve structure I4 comprises a cylindrical body I5 having a centrally disposed opening {6 in the upper portion thereof wherein is provided a valve seat ll for a valve H! which is kept normally seated by means of a tension spring 2 l9. Also formed in the body I5 is a lateral opening which communicates with a passageway 2| extending upwardly in the body ill to a vertical passageway 22 which, in turn, terminates at its upper end in a reservoir 23 in the raised portion l2. The passageway 20 continues to the rear of thebody Ill, and is sealed by means of a removable plug 24. The reservoir 23 is provided with a permanently fixed top 25.
Positioned in the lower end of the recess II is a secondary ink pad 26 which is provided with a plurality of ribs 21 upon its upper face and with a plurality of vertical passages 28 which extend through such ribs and through the body proper:
of such pad 26.
Positioned atop the secondary pad 26 is a gridlike backing plate 29 which is provided with a plurality of vertical slots 30 for the reception of the ribs 21 and, lying atop the plate 29, is an inking pad 3|. A cover 32 is provided for covering the pad 3| when the same is not in use.
In operation, it will be apparent that the device may be filled with ink by removing the plug 24 and filling the same until a sufficient quantity of ink has been received in the passageway 2|, the passageway 22 and the reservoir 23 whereupon the plug 24 may be replaced and the device placed in its, normal condition as shown in Figure'5 of the drawing. The cover 32 may then be removed and when a rubber stamp is, pressed against the pad 3| ink will be removed therefrom to the rubber stamp in conventional manner. However, as this action takes place the downward pressureof the rubber stamp upon the pad 3| will impart a downward movement of the valve I8 to thereby temporarily open the same and allow a flow of ink throughrthe seat I! into the opening I5 and thence into the secondary pad 26. Since this pad 26 is ofan absorbent nature it will tend to hold a goodly quantity of ink which will be delivered not only through contact between the ridges 21 and the pad 3| but directly to the pad 3| through the passageways 28 so that the pad 3| will be kept moistened at all times and automatically by the use thereof with the conventional rubber stamps.
While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without derecess having an inking pad disposed therein adapted for applying ink to a rubber stamp, a portion at one end of said body rising above the other portion of the body, said raised portion containing a reservoir with a removable top cap as a means for filling same, means for automatically delivering ink to said pad consisting of passageways intercommunicating said reservoir and said recess, said passageways provided with a valvemfispringas anneans for-normally holding said valve in aol'ose'd position, said valve being mounted in the bottom portion of said body, and means operable for opening said valve by depressing said pad.
