I i To all whom ma'i concern:

i It is the objectof the invention to provide a simple and effective form of apparatus forembossing metal plates such as. are used in addressing machines for printing the addresses upon the articles or magazines to be sent out to subscribers.

. In. carrying out my invention I employ rotary carriers for the dies withmeans controlled by keys for stopping the said carriers at the roper position to bring the desired pair 0 dies to the printing or stamping point, means being also provided whereby the stamping'action is immediately efvfected upon the carriers assuming the posi tion just described. The invention consists in the features and combination and arrangement of parts here inafter described and out 1n theclaims. g In the accompanylng drawings, Figure 1 particularly pointed is aside view ofa :machine embodying my invention. .Fig. 2 is a plan view of a detail part of the machine.. Fig. 3 is a. bottom plan view of a detail portion of the machine.- Fig. 4 is a detail plan view of the punch,

and Fig. 5is adetail view of one of the dies.

Fig. 6 is-a view ofaform of my invention in whichthe die carriers are arrangedaxially.

n thesedrawings 1 isthe frame of the machine, and 2. is the driving shaft shown in dotted lines and. which is constantly driven in any suitable manner. On the lower endof thisshaft and rigidlysecured thereto is a toothed wheel-or ratchet 3 having onits upper side a cam or incline 4c.

' 5 indicates. a. sleeve carrying a bevel gear 6 which meshes-with a bevel gear, 7 attached to the carrier 8, which has thereon one set ofdies 9,.this carrier. having its shaft 10 ried by a sleevel i, which sleeve has fixed thereto a-die .carrler drum 15.

This sleeve also has fixed. thereto a disk or plate 16 which hason. its underside a cam or incline 1'7 engaging the incline of cam 4: on the ratchet wheel. On the under side ofthis plate 16 there is pivoted 'a yielding stop 18 arranged to engage a pawl 19 also pivoted to the under side of the plate 16, thesaid pawl engaging the ratchet wheel3, before mentioned, so that normally when noprinting is being done the plate or disk 16 together with the sleeve 1 1; the clutch members; the gears 6 and? and the die carrier ing stop 18 is adapted to be carried or revolved' by the revolution of the plate or" disk 16 in a path adjacent a series of stop pins 20, only one of which is shown in the drawings, these stop pins being each controlled by a key-lever 21 extending to a key-board. The function of the clutch members 12,13, is to transmit the movementof the one sleeve 14 to the other 5 and at the same time to allow the carrier drum and associated parts to have axial movement.

The pawl 19 is pressed toward the ratchet by a spring 22 to engage thesaine. A pair of plates or disks 23, 24 are attached to a bracket 25 in turn secured to the frame 1 of the machine, these plates extending respectively above and below the die carrier'drum 15 and the dies carried thereby. The sleeve 14 together with the die carrier drum is pressed downwardly by means of springs 26 extending between the clutch members and bearing thereon. These springs hold the die or matrix carrier in its inactive or lowest position in which it is adapted to rotate. The impression member or plate 16 for pressing the dies or matrices upwardly has a series of notches in its periphery as shown at 27 Fig. 3. Overlying the edge of thisplate is a registering or centering stop or detent 28 which may form part of the fixed bracket 25, the function ofthis registering device being to enter one of the notches 27 when the rotary motion is arrested and the impression plate or member'16 rises togive the printing or stamping effect, this registeringstop or member holding the lower die carrler and the impression plate-accurately in posit on while, the lmpression 1s being made. The punch or impression device is o i a l v:- 8 will be in constant IGVOllltlOll, The y eldcarried by the carrier 8.

and having also a punch projection 30 adapted to engage the lower end or head 31 of the die stem, which at this moment may be lying above it so that upon the elevation of the impression plate 16 this punch will force upwardly the die immediately above it and make the impression in the plate fed to the point w in conjunction with the opposite die on the carrier 8, it being understood that the carrier 8 has thereon a male i operated back to its lowermost position.

In Fig. 2 a plan view of the plate 24 is shown, this having an opening at 33 to receive the punch 29. In the operation of the machine it will be understood that the die carrier 8 and the die carrying drum 15 are normally in rotation. When one of the keys is struck by the operator the corresponding stop pin 20 will be raised into the path of the outer end of the yielding stop and this stop will be turned on its pivot until it strikes the fixed stop 34 on the plate or disk 16. In this movement the stop 18 throws the pawl 19 out of engagement with the ratchet wheel 3 on the constantly rotating drive shaft 2, and at the same time the die carriers are arrested in proper position for printing or stamping the character in the sheet metal or other material which is introduced between these carriers at the point 00. Of course the contact of the stop 18 with the key stop 20 determines the exact position at which the rotary movement is arrested and at this moment one of the notches in the disk or plate 16 lies immediately below the registering stop or wedge 28, the said plate normally clearing this stop by about one-sixteenth of an inch, but as soon as the plate 16 begins to rise the stop 28 engages one of the notches and retains the plate and carrier in its arrested position] As soon as the pawl 19 has been released and the dies or die carriers brought to a stop the continued rotary movement of the ratchet 3 will cause its cam or incline 4 to work against the cam or incline 17 and move upwardly the sleeve 14 together with the plate 16, and the impression device or punch so that the die immediately overlying the punch will be raised to make the impression in conjunction with the male die A number of important results are elfected by this raising movement of the sleeve 14 by means of the portion of the matrix carrying mechanism engages, by one of its notches 27, with the toothed or registering wedge 28. Second, the stop pin 20 is relieved from pressure of the stop 18 because said stop by this upward movement has been raised into a plane above the plane of the end of the key-stop pin 20. Third, the dies are brought together and a character is raised on the metal or other surface. Fourth, as soon as the stop 18 has reached the limit of its upward movement due to the upward movement of the plate 16 it swings over the end of the stop pin 20 and when the high parts of the cam surfaces 4 and 17 have passed each other the downward movement of the matrix carrying mechanism, under the action of the springs 26, will cause the under face of the stop 18 to bear on the upper end of the key stop 20 and force the same back into normal position and the parts will then be ready for another operation by the manipulation of another key, it being understcod that the released pawl 19 has now rengaged with the ratchet wheel and the carriers are again in rotation.

' It will be observed that one set of dies, namely, those marked 9 are rigidly moimted on one of the carriers while the other set of dies are loosely mounted in their carrier or .drum and are adapted to have vertical sliding movement in relation thereto. These dies are arranged between the plates 23, 24, and only that die which is immediately above the punch 29 and opposite its coacting die on the carrier 8 will be operated when the upward movement of the parts takes place. For it will be observed that all the other dies are confined closely between the said plates 23, 24, the said plate 23 having an opening similar to that in plate 24, that is only at or adjacent the printing point for the passage through it of the die to be elevated. It will be clear that the die carriers are connected to rotate in unison and bring mating dies opposite each other. From what has just been said it will be also observed that the matrix carrying drum 15 will slide vertically on all of the dies which are held between the plates 23, 24, excepting the die being operated and this one travels vertically with the said drum under the action of the punch 29. The'die carriers are arranged at right angles to each other, all of the dies excepting the one being operated upon remains in the same planebetween the plates 23, 24.

The springs 26 serve to retract the entire matrix carrying mechanism instead of having individual springs on each of thedies. I do not limit myself in this respect, however, as the individual springs might be used. The springs 26 also effect thereturn of the key stop pins 20 individually to normal position through the action of the stop "18 which as above stated swings over the operated stop pin when the plate 16 is raised. Thehead or shoulder on the lower end of the dies insures the return of theoperated die to its lowermost position.

In Fig. 6 I show a form of my invention in which the die carriers are arranged in coaxial relation. The drum shaft 2 is arranged as before together with the die carrier 15, the toothed wheel 3, the cams or inclines 6L and 1-7, and the pawl and associated parts including the key operated stop whereby the rotary motion is arrested and the closing, embossing or printing motion given. The die carrier 8 however, instead of being placed at right angles to the die a disk or impression plate 16 and a punch 29", all of these being "similar to those parts used in connection withthe die carrier 15. The plate 16 also has a cam surface ori'ncline 17 thereon upon which works a cam 4: fixed tothe shaft 2. The die carriers are pressed normally apart by a spring 26 sur rounding the sleeves and the clutch connections, Now when the rotary motionof the die carriers is arrested by striking a key andthrowing one of the stop pins into action both the dieswill be arrested because the lower die is connected through the interlocking clutch jaws with the upper die carrier, and as soon as these die carriers have been arrested the power will be exerted through bothsets of cams to force the die punches toward each other by means of the impression plates or disks 16, 16 and the dies which are in line with the printing point will be forced together to make the impression, and all the other operations above described concerning the return of the parts to normal position and the resumption of rotary movement of the die carriers will be performed.

Where, in the appended claims, I refer to the dies moving parallel with the axis of rotation or to the axial movement of the dies, it will be understood that I do so generically to apply to both forms of the invention above described, whether the die carriersbe arranged coaxially or with their axes at right angles as first described; whetherboth dies or their carriers have such movement or whether the dies have movement indeconnection with'the dies or die carriers, I

do so ina generic sense whether both dies or both carriers are moved or only one die or one carrier is moved toward its cooperating die or carrier.

' Any suitable form of holder or carrier may be used to present the material to the dies to be embossed thereby. I do not limit myself to the dies movable in relation to their carrier. In the form first described, where the dies are rigidly arranged on one carrier incase any wear occurs on the bearing surface of the matrices the rigidity of the said dies serves to direct the movable dies centrally and prevents breakage.

I have not specifically claimed herein the modified form of the invention shown in Fig. 6, this however being covered by the broader claims herein and made thesubject of specific claims in a co pending application #446336, filed July 31/08. I
