Application April 27, 1943, Serial No. 484,693

- 1 Claim. (o1.1o1 '110 The present invention relates to markin stamping, embossing and similar machines and more particularly to the type where the matter to be stamped is easily changed and truly aligned.

An object of this invention is to provide a novel and improved machine of the type mentioned employing a series of wheels each havin e'qui-spaced marking or embossing characters, as the letters of the alphabet, numerals or other insignia on the periphery thereof; each wheel being capable by a single means, of being re- 'volved any required amount independently of the others, and all to be locked against rotary inovement when characters composing the matter to be stamped or embossed, are presented in opersting position.

Another object hereof is to provide a machine bf the class set forth, of novel and improved con- 'struction where the wheel rotator is automatiball'y shifted into true operating position with {respect to any of the wheels, a little ahead of the operators manual manipulation, whereby accuracy of operating position of said wheelrotator is assured independent of the operators adjustment, and where the rotary movement of the. wheel from character to character thereon into operating position is automatically shifted into true position, a little ahead of operators manual manipulation, whereby accuracy of operating position of each wheel is assured independent of the operators adjustment.

A further object is to provide a novel and improved machine of the character described where the depth of the embossing or amount of impression is controllable.

A further object hereof is-to provide a machine of the class mentioned of novel and improved construction, adaptable for imbedding metal leaf into the impressions embossed on objects, as for instance the names on wood pencils or designs impressed on leather hat bands or gold leaf stampings on book covers or similar work.

Still another object of this invention is to provide a novel and improved machine of the nature described which is simple to set up and operate,i compact, positive in action, and efficient in carrying out the purposes for which it is designed.

' Other objects and advantages will become manifest as this disclosure proceeds.

Fig. 7 is a side View of a portion of the machine of Fig. 1, at the left-hand side thereof.

In the drawings, the numeral l5, designates generally a casing for housing the stamping or embossing mechanism. A shaft I6, is slidably mounted through said housing and its ends protrude exteriorally therefrom. Said shaft l6, has a knob l! at one end, and a head [8 at the other of itsends. The head I8 i housed within a hollow knob l 9 of a tubular member 20. This member 20, is exteriorally threaded at 2|, at which portion it is threadedly engaged with the casing l5. Member 20 is a sleeve on the shaft [6. The chamber 22, isof adimension along the line of the shaft Hi, to permit a comparatively short longitudinal movement of said shaft thru member 20; head l8 serving to limit such movement.

Said shaft It, carries securely mounted thereon, a gear 23, and also the brackets 24 and 25,

through which said shaft is rotatable. A plate 26, on which said brackets 24 and 25 are securely mounted, maintains said brackets, over at each side of the gear 23, and in contact with the latter, so that upon longitudinal movement of shaft I6, the plate 26 and the brackets 24 and 25 carried by said plate, are moved along with the gear A series of gear wheels 27, all of identical size and each having the same number of equi-spaced teeth, are carried on the tubular member 28,

and each wheel is independently axially rotatable preferably are of heat-insulative material; if it is desired to include a preferably electric heating coil 3! within the tube 28 for purposes hereinafter explained, so that only the wheels 2'! are heatedandthe rest of the device substantially insulated from the effect of said heating means. The collars 29 and 30 are securely mounted within the casing l5 wherebythe tube 28 is firmly positioned.

The peripheral surface of each tooth of each of the wheels21, isan embossing or stamping element. Forins'tance each wheel 21 'may have thirty-six teeth; so that the embossing or stamping elements would compose the complete alphabet and the numerals from zero to nine. Of course, said embossing or stampingelementmay be of any desired insignia or character. yThe,respective aligned teeth of wheelsf2l, at position 5!, comprise the matter tobe. embossed onto for instance a pencil 32, positioned on Vfblo,ck-3.3Y, ,carried by member 34, the arm 35 of which is Saidmempivotally mounted at 35 on frame-31..

Upon entrance of said ball .428 .intolthe .first holell's, which is opponent to theoperators feel and is accompanied byianaudible click, knob 19 is let go. Gear 23 is now in engagement with the teeth of the first wheel 21 at the extreme'left of the casing l5 andsaid first wheel 21 is free of yestra-intby plate ZGbecause said wheel is free thru slot ;86 in plate 26 which slot is co-planar with ge r .23. he operator, by observing the notations by aid of indicator 52, and by turning knob t7, will thereby cause gear 23 to turn said first Wheel 21 an amount so that the required firstcharacter is in'position 3|. The actionof spring 50 on ball v48, as gear 23 is rotated, will be to automatically urge the operator to accelerate the rotary movementv of knob [1, for said ball is strongly urged into engagement with the succeeding hole .49. flit is to be noted that when ball 43 ,is in any of the holes 45, gear 23 is in true co-planarzaiignmentLand full engagement with one of the wheels :21, and that when ball t8 is in any of the holes .49, a tooth of such engaged wheel 2! is in true operating position 3!. When the required character of the-first wheel 21 is in position 3|, the knob I9 is again turned counterclockwise to bring gear 23 into engagement with the next wheel 21 and then knob I1 is again operated, subject to like incident as explained, as is evident to set all the wheels 21, so that in aggregate, their teeth presented at position 31 comprise the matter to be stamped onto the object 32.

It is important to note that all the wheels 21, are locked against rotary movement by plate 26, except the particular wheel 21 which is aligned and in engagement with the gear 23. After all the wheels 21 have been properly arranged, gear 23 is returned to the extreme left rest position out of contact with any of the wheels 21, in which position, all of said wheels 21 will be locked by the plate 26.

By operating handle 40, cam 38, will raise holder 34, and cause an impression of the stamping or embossing characters at position 3|, onto the object 32. Return of handle 43, to initial position, will cause holder 34 to fall, and object 32, can now be removed and replaced by another for repetition of the cycle of operation. The depth of impression can be regulated by adjustment of position of wedge 12, to lower or raise the holder 34, and thus initially set same.

The ribbon member 53 may carry an inking substance or, metal foil for inlay into the embossed characters, aided by heat aforementioned, or for gold stamping where the characters are printing type. The operation of the feeding mechanism of such ribbon member 53, is effected upon movement of bell crank 68, caused by pin in its travel with cam 38, once during each cycle, whereby pawl 66 will cause a slight rotary movement of rollers 60 and (ii, to present a fresh portion of said ribbon at operating position 3|.

This invention is capable of various forms and numerous applications without departing from the essential features herein disclosed. It is therefore intended and desired that the embodiment set forth herein be deemed illustrative and not restrictive, and that the patent shall cover all patentable novelty taught herein; reference being bad to the following claim rather than to the specific description herein to indicate the scope of this invention.
