STAMPING MACHINE Filed June 5, 1933 Patented Apr. 3, 1934 STAMPING MACHINE Arthur M. Wickwire, Jr., Nutley, N. J assignor to Peerless Roll Leaf Co. Inc., Union City, N. J a corporation of New York Application June 5, 1933, Serial No. 674,383

9 Claims.

This invention relates to monogram or other small type press or stamping machine.

An object of the invention is the provision of a press of small size, as for the letter types of a monogram, the chase being mounted for ready insertion or substitution of the letter types by movement to a position of convenience for insertion or substitution of the monogram type, the assembly being arranged to effect rigidity of the chase and the thereto connected parts during the stage of impressing.

More specifically, the chase holder is rigidly secured to a plunger which is longitudinally slidably mounted in a vertical frame support, the plunger being operated by a cam or other lever pivotally mounted upon the vertical frame support and guided by pin and slot connection thereby, the plunger being normally held within its vertical frame support by suitable spring means, such as a retractile coil spring or preferably a pair of such springs at each side. The spring means enable the plunger to be reciprocated and retained in type setting position, in which movement the plunger swings upon its pins within their slots.

A feature of the invention is the employment of a single element represented by the above referred to plunger, to which the chase holder is rigidly secured and which single element is operated by the manipulated cam or other lever.

A feature of the invention is the assembly of such single element represented by the above referred to plunger, disposed in a frame presenting a guideway in which the single element is reciprocated, a connection affording pivotal movement of such single element relative to the frame and resilient means serving tertially to retain the single element in its reciprocation in such guideway, to effect the return of the single element in its return movement and to hold the single element and therewith the chase holder in stable position when the chase holder is moved to tight setting position.

Further features and objects of the invention will be more fully understood from the following detail description and the accompanying drawing, in which Fig. 1 is a side elevation, partly broken away in vertical section, of a stamping machine embodying myinvention; the dot and dash position of the plunger and thereon supported chase indicates the position for insertion of the type;

Fig. 2 is a front elevation of Fig. 1, a part of the take-up reel being broken away.

Referring to the drawing, the frame 10 is suit- The plunger 13 is reciprocally mounted within the guideway 14 by means of the upwardly disposed, oppositely projecting pins 16, 16, received within the respective vertically extending slots 17, 17, supplemented by suitable spring means 18, serving to normally hold the plunger upwardly and inwardly relative to the guideway 14, and the pins 19, 19, coacting with the spring means and also with the plunger in its movement in the guideway.

Such spring means is advantageously in the form of individual oppositely disposed retractile coil springs 18, 18, respectively extending from the pins 19, 19, which are secured to and extending laterally of the plunger 13, and the spring anchoring pins 20, 20, secured to the frame 10. Preferably, the positions of the pins 20 are related to the pins 16 to tension the plunger 13 toward and upwardly within the inner face of its guideway 14 in the frame 10, and to be eccentric relative to the positions of the pins 19 and the pins 16 when the plunger 13 and the chase 12 are moved to type setting position.

The plunger 13 is operated by any suitable means. A convenient operating means is in the form of a cam lever comprising the cam element 21 secured to or integral with operating arm 22, the free end of which is provided with a handpiece 23. The arm 22 is shown pivoted at 23a to the frame 10.

The stamping machine is advantageously operated with embossing media, and for this purpose I provide a ribbon 24 of suitable embossing material, such as regulation so-called roll leaf, that is, a strip of paper serving as the carrier, on a face of which is a layer of unctuous or other heat releasing material, upon which is deposited the embossing medium proper, such as genuine gold leaf, comminuted metal leaf in imitation of genuine leaf, such as various brass alloys, or aluminum alloys in imitation of silver and other genuine metal media. The embossing medium may be in the form of colors deposited upon the unctuous, i.e. heat releasing layer. The outer face of the metallic or color medium is preferably sized. For such form of embossing the chase 12 is provided with suitable heating means, such as an electric resistance coil, indicated diagrammatically at 25, to which the cord 26 is connected. Desirably, a thermostat indicated diagrammatically at 27, is inciuded in the circuit of the electric resistance coil 25, to ensure substantially uniform heating, and avoid excessive heating. The cord 26 passes freely through the slot 10a formed within the frame 10 and is of suflicient length to permit the plunger 13 to be moved to its type setting position. Monogram or other type is indicated at 28.

The indicated embossing ribbon may be fed from the reel 28 to the take-up reel 29 by any suitable means, as by a ratchet and pawl take up mechanism, viz., a ratchet wheel 36, pawl 31, the latter operated by the lever 82 on which it is pivotally mounted and tensioned by its biasing spring 33, the lever 32 being provided with the pin 34 which is normally received within the recess 35, disposed in the rear of the chase holder 12, whereby upon upward movement of the plunger 13, the ratchet wheel is operated to cause a predetermined amount of the ribbon 24 to be fed.

The ribbon 24 is shown passing about the guide pins 36, 36, disposed on opposite sides of the chase 12, the pins 36, 36 being in substantially horizontal relationship and at a level below the maximum vertical movement of the type 28, whereby the used ribbon portion is readily stripped from the stationery or other material stamped.

The spring pressed pawl 37 and its indicated associated ratchet wheel serve as holding means for the reel 29 during the stage of return movement of the feeding pawl 31, and otherwise for preventing the reel 29 from reverse rotation.

The embodiment illustrated in the drawing is particularly designed for effective operation by persons relatively unskilled in the technical art of printing, such as by sales people in department stores, stationery stores, drug stores, and the like, where writing paper, envelopes, and the like are for sale.

My stamping machine enables monograms and other relatively brief printed matter to be impressed conveniently and with great rapidity. Auxiliary devices, such as the guide pins 40 and co-ordinately spaced vertical recesses 41 are provided for properly registering the material to be impressed relative to the monogram or other type 28.

The oppositely disposed spring fingers 42 serve to limit the upward movement of the material impressed succeeding the stamping operation; that is to say, in impressing material with heat releasable embossing and other impression medium, the type characters 28 in the chase 12 are heated by the heating coil 25, and upon downward movement of the plunger 13 the type engage the paper side of the impression strip 24, the type and the engaged ribbon portion 24, continuing in such downward movement until contact is made by the sized face of the ribbon 24 upon the material to be stamped. Accordingly, the unctuous material and underlying metallic or color layers are heated and released from the paper carrier upon the material impressed, accurately conforming to the contours of the type 28, the unctuous material after cooling serving as a sizing for the deposited metallic or color impression.

In like manner, leather, fabrics, and other suitable material may be embossed or otherwise stamped.

From the above, it is apparent that my invention provides for a base, a vertically extending arm rigidly secured to the base, the arm being provided with a slot extending to a vertical face of the arm to afford a guideway, a plunger vertically reciprocated in the quickway, the plunger being mounted in the guideway by pin and slot connection, the last-named slot extending substantially vertically, and pins carried by the plunger at its portion thereof extending beyond the guideway and adapted to ride upon the facial areas of the guideway in the vertical reciprocation of the plunger, and coil springs secured to such pins tending to normally hold the plunger within the guideway and upwardly toward nonimpressing position.

Such pin and slot mounting means of the plunger and such coil spring means preferably serve also to hold the plunger stable when moved to type inserting position.

By the provision of the slot in the arm, the electric cable or wiring connected with the electric heating coil, mounted in or upon the chase, is readily accommodated, and also retracted and protected within the slot during the stage of impressing.

It is observed thatthe cam 21 serves as a stop for limiting the movement of the plunger 13 and therewith of the chase 12 under the action of the springs 18 to type inserting or changing position.

From the above, it appears that a feature of my invention the employment of a single element to which the chase holder is rigidly secured and which single element is operated by the manipulated cam or other lever.

The above sets forth as a feature of my invention the assembly of a single element disposed in a frame presenting a vertically extended guideway in which the single element is reciprocated, the pin and slot connection affording pivotal relationship of such single element relative to the frame and cooperating with suitable means represented by the retractile coil springs associated with pins carried by the single element, such retractile coil springs or equivalent serving in coaction with the pins to retain and positively guide the single element in its reciprocation in the guideway, both in its impression movement under actuation of the manipulated means and in its return movement, and further serving in coaction with the pin and slot connection to facilitate movement of the single element and the therewith carried chase holder to type setting or changing position and to hold the single element and the chase holder in stable position in type setting or changing position.

Whereas I have described my invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made without departing from the spirit of the invention.
