1 Claim. 1

This invention relates to means for stamping or impressing indicia and/or designs on articles, and deals more specifically with a stamping press for stamping on leather, wood, paper, plastic materials, etc.

The main object of the invention is to provide a stamping press wherein all the essential preparatory and stamping operations are carried out in a convenient and expeditious manner.

Another object of the invention is to provide a stamping press which embodies means for heating the stamping die or block prior to employing the same for stamping purposes.

Another object of the invention is to provide a stamping press which employs a color or metallic color bearing tape or ribbon and providing for automatic feed of said tape or ribbon according to the general size of the article to be stamped.

A further object of the invention is to provide a stamping press in which feed means for the mentioned tape or ribbon is operated by the article to be stamped upon positioning the same in the press.

A still further object of the invention is to provide a stamping press embodying novel means for applying stamping pressure.

My invention also has for its objects to provide such means that are positive in operation, convenient in use, easily installed in a working position and easily disconnected therefrom, economical of manufacture, relatively simple, and of general superiority and serviceability.

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description. However, the drawings merely show and the following description merely describes one embodiment of the present invention, which is given by way of illustration or example only.

In the drawings, like reference characters designate similar parts in the several views.

Fig. 1 is a top plan view of a stamping press embodying the present invention.

Fig. 2 is a longitudinal sectional view thereof as taken on the line 2--2 of Fig. 1.

Fig. 3 is a broken cross-sectional view taken on the line 3-3 of Fig. 2.

The stamping press which is illustrated comprises, generally, a housing 5, means 6 for heating a stamping block or die D, a frame I for holding said die, a frame 8 yieldingly mounted on the housing and receptive of the frame 1, gauge means 9 for locating an article A to be stamped movable by said article to feed a ribbon R. across the face of the article A, and means I! mounted on the housing for depressing the die to cause an impression to be made, through the ribbon, on the article.

The housing is formed to have a top wall l2, side walls l3 and a rear wall l4. Said housing is formed with a sloping wall [5 which is provided with a large rectangular opening it, said wall forming an obtuse angle with the top wall I2. Laterally spaced flanges I! or the like extend outwardly from the sloping wall I 5 and serve to guide and locate the die-bearing frame I for positioning the die D in the opening I6.

The means 6 comprises a pyramidal reflector housing I8 carried by the inner face of the wall l5, a suitable lamp socket I9 at the apex of said housing, and a heating lamp 20, preferably of the infra-red type mounted in said socket and A disposed within the reflector housing l8. Electric current may be brought to the lamp socket [9 through the medium of a plug 2| on the end of a conductor 22 or connected to a suitable current source.

The die D may vary and be an engraving cut, type, or a stamping cut. The frame I therefor consists of a rectangular frame 23 mounting one or more feed screws 24, each operated by a handle 25, and adapted to move clamp blocks 26 relatively toward and from each other for clamping a die D in the frame 1.

The frame 8 comprises a rectangular frame 21 mounted to be parallel to the housing wall l2 on locating studs 28 set upright on said wall. A compression spring 29 around each stud I28 yieldingly supports the frame 8 for movement toward and from the housing 5. The frame 8 is of a size to slidingly receive and hold the frame I and thereby hold the die D in spaced parallel relation to the housing wall l2.

The means 9 consists of a lateral guide 3|] and a transverse guide 3| adjustably mounted on the housing wall l2 and locked thereto by means such as screw studs 32 slidable in slots 33 formed in said wall.

The means In comprises a bar or the like 34 arranged across the housing wall l2 parallel to the guide 3|, a longitudinally arranged gear rack 35 connected to the bar 34 as by an extension 36 movable in a slot 31 formed in the wall 12, a support bracket 38 for the gear rack, a gear 39 engaged with the rack and rotated thereby upon longitudinal movement of the latter, and means operable by rotation of said gear during moveand with relation to the die, means It! operably ment of the rack, in one direction, to effect feed causes feed rotation of rolls, 4|

of the ribbon R. The latter means includes bevel gearing 40 and feed rolls 4| and 42 driven thereby and arranged along one inner side of the housing 5. A one-way clutch 43 is embodied in the connection between the gear 39 and the bevel gearing 4|] so that only upon movement of the bar 34 and of the gear rack 35 will the rolls 4| and 42, rotate to effect the mentioned feed of the ribbon R.

The ribbon R;is.gener ally conventional and may be a cellulosic tape on one side of which is provided a transferable coating of color, metal or the like.

The means I comprises spaced frame members 44 extending across the housing 5, a pivot pin 45' extending between the frame members. 44, a manually operable lever 46 carried onsaid pivot pin, and a squeegee roller 41' on said lever for engagement with the die D by manually; tilting the lever 46 on its pivot.

I-noperation, a die D is clamped in the frame I; and the latter placed as shown by the dot-dash.

lines of Fig. 2 for heating by the means 6. While the die is being heated, an article A to be stamped is placed on the wall l2 by sliding the same along said wall until it engages the bar34. Continued sliding, of. the articlewill bring said bar against the guide 3| as, shown. Accordingly, the initial set position of said, guide determines the degree of movement of bar 34. The movement of bar 34 isimparted to the gear, rack35which was initially held.in retractedposition, by. a spring 48. Movement of the rack, through gearing 39 and 49, and 42 and, consequently, feed of theribbonR, said feed being commensurate to the movement of the rack. Thev die frame I. is then removed from heating positionand placed in the frame 8, beneath the squeegee The latter is, then swung back and forth so that the squeegeeroller 4'! wipes across the die to depress the same and the frames 1 and 8 on the studs, 28 to accomplish stamping of the article A. by the heated die through the ribbon R.

The article A is then removed and the spring 48. becomes effective to retract the rack 35 and the bar 34 the one-way clutch 43 permitting such retraction without reverse rotation of the feed rolls 4| and 42, Another stamping operation can then be performed,

While I have illustrated and described what I now regard as the preferred embodiment of my. invention, the constructionis, of course, subject to modifications without departing from the spirit and scope of my invention. I, therefore, do not wish to restrict myself to the particular form of construction illustrated and described, but desire to avail myself of all modifications that ma fall within the scope of the appended claims.

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

A press of the character described, comprising, in combination, a housinghaying a horizontal top wall and a sloping front wall having an opening and forming an obtuse angle with the top wall; a frame resiliently mounted on and spaced from the top wall. in parallel relation thereto, said frame having spaced lateral flanges; similarly spaced flanges 0n the sloping wall and aligned with the flanges of the frame; a die-holding frame manually slidable along a straight line from a position between the flanges on the sloping wall to a position between the flanges of the resilientlymounted frame; means for heating the die in the die'holding frame While in, position. between the flanges on the sloping Wall, said heating. means. being carried by said sloping wall and positioned.

to direct heat through the opening in the, latter wall; and means carried by the horizontal, top wall for engaging-the die of the die-holding frame While said latter frameis disposed between theflanges of the resiliently-mounted frame to de-.

press the same in a direction: toward. said; horizontal top wall.
