Application filed March 8. 1924,Seria1Nof3tg807g Renewed September 24, 1925.

T all whom it mag concern:

Be it'known that I, RUBY EVA 'PADMAN, a subject of the King of Great Britain, re-

siding at No. 8 Trevallyn Road, Launceston,

in the State of Tasmania and Common-- wealth ofAustralia, haveinvented a new and useful Improvement 111 Typewrlters, of which the followlng lsaspeclfication. V

- My invention consists essentially in the combination with a typewriter of a 'date stamp so arranged as that, on depressing a ke the rearran ed date on thestam is' first inked and then printed on the letter, invoice, circular or the like which has previously been placed in position inthe typewriter, the date stamp being returned to its normal position on the finger ofthe operator being lifted from the key.

It is obvious that thezdate stamp may be applied to a typewriter in various ways, to effect the desired result. I will now describe one means by which a date stamp may be combined with a typewriter, so that, on depressing a key, said date stamp is caused to travel forward, without revolving, against a hinged inking pad in front thereof, thus transferring the necessary amount of ink from the pad to the prearranged date on the date stamp. The further forward movement of the date stamp causes the hinged inking pad to drop, permitting the date stamp to complete its travel and imprint its previously inked date upon the letter, invoice, circular or the like, in position in the typewriter. When this has been efiected, and the finger of the operator has'been removed from the said key, a spring returns the date stamp to its original position, and another spring returns the hinged inking pad to its original position, ready for impressing the same date on the next letter, invoice, or circular.

The date stamp and its appurtenant parts are contained within a suitable casing which may be formed integral with the right hand end of the frame of a typewriter, or attached thereto in any approved way. In the drawings hereto annexed, I have shown the date stamp and its appurtenant parts at- 0 taohed to the right hand end of the frame of an Underwood typewriter.

Referring to the drawings hereto annexed Figure 1 is a plan View of the date stamp 5 and its appurtenant parts within the casing beforev referred to, bemgremoved.

Figure 2 is a side elevation of Figure 1,

one "of. the sides of the casing being removed. Figure 3 1s a s1deelevat1on-of the casing, one of its sides being removed, and showing the position ofthe date stamp and its appurtenant parts, when theikey has been depr'essed tojlprint the necessary date on the letter, invoice, or circular in the typewriter.

Figure 4: isa plan view of portion of an Underwood typewriter, 'ShOWIHg my inven" tion attached thereto,the date stamp and it's appurtenant parts being in the position they occupy after the date has been printed.

Figure 5 is a planview of portionof the casing, showing the meansfor clamping it to the right hand end of the frame of the typewriter. I I 1 i Figure 6 is a side elevation of Figure 5. 1 is aidate stamp:consistingoffour rubber-faced rollers, carrying in relief the necessary figures and letters to constitute a date. 2 is a horizontal nonrotatable spindle, on which these rollers are mounted. 3 are coiled springs on the said spindle 2, which press the rollers thereon to ether,

the cover of the casing and prevent them revolving after t e dethe date stamp 1, one end of said rod being formed integral with one of the horizontal bars i and the other to the opposite one, and consequently adapted to move to and fro with said bars 4;. 9'is another horizontal rod extending across the casing at the other end thereof and being formed integral with said casing. 10 is a lazy-tongs lever, one end of which engages with horizontal rod 8 and the other with horizontal rod 9. is a key the inner end of which is a continuation of portion of said lazy-tongs lever, and which key projects through a slot (not shown) in that end of the casing 6' at the opposite end to the date stamp 1. 12 is a container for an inking pad 13, said container being hinged at 14 to the bottom of the front of the casing 6. 15 is a coiled spring for normally keeping said hinged travel and the typewriter.

inking pad in its closed position. 16 is another coiled spring connected at one end to the back of the casing, and, at its other end, to that portion of the lazy-tongs lever adjacent thereto. 19 is the clamp for clamping the casing 6 to the right hand end of the frame of the typewriter.

A will be clearly understood, on depressing he key 11, the lazy-tongs lever 10 is caused to expand against the resistance-of the spring 16, thus causing the date stamp 1 to travel forward, as previously explained, and without revolving against the hinged inking pad 13. The further forward movement of the date stamp overcomes the resistance of the spring 15 and causes the hinged inking pad to drop, thereby per-,

mitting the said date stamp to complete its print its previously arranged date on the letter, invoice, or circular, in

When this has been effected, spring 16, on the removal of the operators finger from the key 11, returns the said date stamp to its normal position within the casing 6, and spring 15 returns the said hinged inking pad to its closed position, ready for the next operation.

I claim 1. In a typewriter the combination therewith of a datestamp, means for causing said stamp to travel forward without revolving, first against a hinged inking pad which it causes to fall, and secondly, against a letter, invoice, circular, or the like, in the typewriter, in order to impress the necessary date thereon, and springs for returning both said date stamp and hinged inking pad to their normal positions.

2. In a typewriter, a casing built either into or attached to, the right hand end of the frame of the typewriter, a date stamp carried on a horizontal spindle atone end of said casing, a horizontal bar on either side of the casing, and capable of sliding to and fro in guides on the inside of said casing, said bars being each connected at one end to said horizontal spindle, and at right angles thereto, a horizontal rod behind and parallel with said date stamp and capable of moving with said horizontal bars, a horizontal rod near the other end of the casing and parallel with the previously mentioned horizontal rod, a lazy-tongs lever between and connected to said rods, a key, by depressing which said lever is expanded to op erate the said, date stamp, a hinged inking pad in front of the said date stamp, a hinged cover to said casing, and springs for returning both said date stamp and hinged inking pad to their" normal positions, when required.
