Description

May 31, 1955 w. K. MUNSON STAMP PADS Filed June 10, 1954 u r ATldII/IlalllfIIIllIIIIIIIIllI/IIIII i in-HE N w MN TU NM WK mv E N n H w nited States This invention relates to inking pads, commonly referred to as stamp pads, used in inking hand stamps of various kinds and classes. More particularly, the invention deals with the provision of means on the pad proper of devices of this type and kind to facilitate automatic movement of the inking pad int-o closed operative position in the casing in the operation of reinking the reservoirs of the device, so that this operation can be performed without soiling the hands.

Still more particularly, the invention deals with a means of the character described which can be readily clipped into edge portions of the inking pad.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which cer tain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:

Fig. 1 is a plan view of a stamp pad showing the cover in raised position, with part of the construction broken away.

Fig. 2 is an enlarged section substantially on the line 2-2 of Fig. 1.

Fig. 3 is a section on the line 3-3 of Fig. 2 showing only part of the pad frame in section; and

Fig. 4 is a perspective view of one of the closure devices which I employ.

This application is a continuation-in-part of a structure shown in my prior application, filed January 19, 1954, hearing Serial Number 405,004.

In Figs. 1 to 3, inclusive, I have indicated at a body portion, or casing, of the stamp pad device, this body portion or casing being preferably formed of rubber so as to render the same flexible for purposes later described. The casing 10 has a raised wall portion 11 which is set inwardly with respect to the front and sides of the casing and in alinement with the rear of the casing and this raised wall has, at rear corner portions of the casing, apertures 12 to receive pivot pins 13 of a rectangular pad frame 14 of a flexible pad 15, part of the frame 14 being indicated in elevation in Fig. 2 of the drawing. The forward edge portion of the frame 14 also includes laterally projecting pins 16, one of which is shown in section in Fig. 3 of the drawing and these pins are adapted to enter apertures 17 in the raised wall 11 and also extending into the base 10 of the casing, as will clearly appear from a consideration of Fig. 2 of the drawing.

Adjacent the apertures 17, the base 10 has recesses 18 for reception of pad actuating elements 19, one of which is indicated detached in Fig. 4 of the drawing. The base 10 of the casing has spaced wells, or reservoirs, 20, in which suitable absorbent pads are arranged and part of one of these pads is indicated at 21 in Fig. 1 of the drawing. The pads 21 are inked when the stamp pad is in raised position and, then, ink is transferred from the pads 21 to the stamp pad 15 when the pad is lowered to its normal position.

The elements 19 are both of the same construction so atent O a 2,709,415 Patented May 31, 1955 that the brief description of one will apply to both. Each element comprises a rectangular plate 22, having, at one side thereof, an extension 23, upper and lower edges of the extension having inturned grippers 24 adapted to be forced onto the edge portion of the pad 15, including the frame 14 thereof, in positioning the elements at the forward corner portions of the pad 15 so that either upper and

edge portions

25, 25 of the plate can be disposed above the upper edge of the wall 11 and/or extend into the recess 18. This particular description is given by reason of the fact that it will be apparent that the pad 15 is reversibly mounted in the casing; thus, in reversing the pad, the edge portions 25, at one time, can be upward and, in the next instance, will be downward. The plate 22 includes a rectangular aperture 26 for receiving the projecting pins 16, as clearly noted in Fig. 3 of the drawing. It will be noted from Fig. 3 of the drawing that the wall 11 has slits 27 opening into the apertures 17. These slits facilitate forcible downward movement of the pins into the apertures 17.

At this time, it may be well to point out that, in reinking the stamp pad, the first step is to swing the inking pad 15 into raised position on the pivots 12. This is accomplished by flexing the front corner portions of the casing 10 downwardly, which results in ejecting the protruding pins 16 from the apertures 17. Then, one of these pins can be engaged by the finger of the hand to swing the pad upwardly. After the inking operation has been performed, the inking pad 15 can be lowered by hand without touching the pad proper until the pins 16 rest upon the upper surface of the wall 11, after which, the cover 28 of the casing 10 can be swung into its closed position, in which operation the cover 28 strikes the elements 19 and forces said elements, including the forward edge portion of the pad 15, downwardly until the pins 16 extend into the apertures 17. The inking pad 15 is now in condition for use and retaining against accidental displacement from the casing 10.

The cover 28 is pivoted to raised pivot portions 29 i at the rear corners of the casing 10 and the wall 11, as well as part of the casing 10, is recessed to receive a coil spring 30, which operates to automatically move the cover 28 into raised position, when the cover is released by forward flexing of a catch 31 on the casing 10 to free an elongated head 32 on the cover 28.

By slightly modifying the normal structure of the casing 10 to provide the recesses 18 and the slits 27, my standardized type of pad structure can be adapted to the new use by simply mounting actuating elements, such as the elements 19, directly on side portions of the pad 15 adjacent forward corner portions of the pad. Fur ther, by fashioning the elements 19 in the manner described, the pad can be reversed in the casing to facilitate use of both side surfaces of the inking pad 15.

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

1. The combination with a stamp pad device, comprising a casing, an inking pad pivotally and reversibly mounted in the casing and a hinged cover forming a closure for said inking pad, of a pair of actuating elements secured to the inking pad at edge portions remote from the pivot edge portions of the pad, said elements comprising rectangular plates forming upwardly and downwardly extending actuating edge portions, one side edge portion of each plate having, centrally thereof, projecting means adapted to operatively engage the inking pad in retaining the elements on said pad, said inking pad having protruding pins at said last named edge portions, and said elements being apertured to receive said pins.

2. The combination with a stamp pad device, comprising a casing, an inking pad pivotally and reversibly mounted in the casing and a hinged cover forming a closure for said inking pad, of a pair of actuating elements secured to the inking pad at edge portions remote from the pivot edge portions of the pad, said elements comprising rectangular plates forming upwardly and downwardly extending actuating edge portions, one side edge portion of each plate having, centrally thereof, projecting means adapted to operatively engage the inking pad in retaining the elements on said pad, said inking pad having protruding pins at said last named edge portions, said elements being apertured to receive said pins, and said means of each element comprising a pair of grippers.

3. The combination with a stamp pad device, comprising a casing, an inking pad pivotally and reversibly mounted in the casing and a hinged cover forming a closure for said inking pad, a pair of actuating elements secured to the inking pad at edge portions remote from the pivot edge portions of the pad, said elements comprising rectangular plates forming upwardly and downwardly extending actuating edge portions, one side edge portion of each plate having, centrally thereof, projecting means adapted to operatively engage the inking pad in retaining the elements on said pad, said inking pad having protruding pins at said last named edge portions, said elements being apertured to receive said pins, said means of each element comprising a pair of grippers, and corner portions of the casing, adjacent said elements, being recessed to receive said elements.

4. In stamp pads of the character described, an actuating element, comprising a rectangular plate, an aperture in said plate centrally with respect to opposed upper and lower edge portions, one side edge portion of the plate, centrally thereof, having an outward projection, and said projection including a pair of grippers for operatively engaging a support.
