- To all whom it may concern.-

Be it known that I, CYRUS HAWKINS, a citizen of the United States, residing inthe city and county of Camden, State of New Jersey, have invented a new and useful Press for Printing and Embossing, of which the follow ing is a specification.

My invention relates to an embossing-machine; and it consists of a rotary die-holder and means for operating the same.

It further consists of novel means for inking the die, whereby the ink is applied to said die directly from the ink-fountain.

It further consists in improved means for locking said die when in operative position.

It further consists in means for operating the inking mechanism.

It further consists in means for actuating the counter-die.

It further consists in novel details of construction, all as will be hereinafter fully set forth.

Figure 1 represents a side elevation of an embossing-machine embodying my invention. Fig. 2 represents an end view thereof. Fig. 3 represents a side elevation of a portion of the machine on an enlarged scale. Fig. 4 represents a side elevation of a portion of the device, showing the rotary holder and a por tion of the inking mechanism. Fig. 5 represents a portion of the device, showing guides for the die-holder.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates the frame of the embossing-machine, which carries in suitable journals thereon a drive-shaft 2, and mounted upon said drive-shaft is a drive-pulley 3, to which power is supplied in any convenient manner or suitable source. Mounted on the shaft 2 is a clutch 4, which can be operated by the yoke 5, carried on the arm 6, so that the shaft 2 can be rotated or not, as desired. Suitably mounted on the shaft 2 is a pinion-gear 7, which meshes with the gear 8, carried on the shaft 9, suitably mounted in journals on the frame 1.

10 designates a mutilated gear which is mounted on said shaft 9, in the present instance by the key 11, said gear being secured in its adjusted position by a set-screw 12, whereby it will be understood that said mutilated gear 10 can be moved backward and forward on said shaft 9for purposes to be hereinafter described.

13 designates a die drive-gear which is adapted to mesh with the teeth on the mutilated gear 10 when the same is in proper position therefor and is mounted upon the shaft 14, suitably journaled in the frame 1 of the machine. Carried on the outer end of said shaft 14 is the rotary arm 15, which is provided with a suitable track or groove in which is mounted a sliding carrier 16, said i carrier having suitable connection therewith. The die-holder or chuck 17, which projects thereform,is so mounted as to travel on the track 18, which is movably secured to the frame 1 of the machine and is provided with the upper flattened portions or faces 19 and with the lowered flattened portions or faces 20, the track and intermediate flattened portions being curved, as best understood from Figs. 2 and 4, it being seen and best understood from Fig. 4 that the die-holder or chuck 17 is pivoted, as at 21, to a sliding carrier 16 and that a spring 22 is connected with said die-holder or chuck at one side of the pivotal point 21 and the opposite end of said spring is suitably secured to the rotary arm 15, while a spring 23 is also connected with said rotary arm 15 and at a suitable point'with the sliding carrier 16, it being understood that the spring 23 tends to draw in the sliding carrier 16, and

with it the holder or chuck 17 for the die or bed, which will be called die-holder here in, but which may evidently be used for beds which are not strictly dies, so that the same is always held at a proper tension against the track 18, while the spring 22 tends to hold the die-holder or chuck in the proper position against the flattened faces 19 and 20 of said track 18, it being seen that when the shaft 1.4 rotates it carries with it the rotary arm 15, as well as the sliding carrier 16 and the dieholder or chuck 17 which latter is thus.

caused to travel around the track 18 and in a straight or horizontal line when the same is in contact with the said faces 19 and 20 of said track 18.

the drawings I have shown the same as secured to the latter, said segment rotating with said arm and sliding carrier and adapted to engage in its movement with the gear 24, which is carried on the shaft 25, which is suitably journaled in the walls of the ink fountain or receptacle 26, the latter being suitably connected or supported on the frame 1 of the machine. In the drawin s I have shown the same as attached to oneIeg thereof, so that the segment 23 will contact with the gear 24 after the impression has been made and the rotary arm 16 is passing to its lowermost position. Mounted on the shaft are means for inking the die, it being evident that any suitable device can be employed which takes up the ink from the fountain 26 and contacts with the die at the proper time.

' In the drawings I have shown a part roller 27 ,which is normally in the position seen in dotted lines, Fig. 2-that is, in contact with or immersed in the inksaid part roller 27 being adapted to assume the osition seen in Fig. 4,that is, in contact wit the die 28in order to ink the same when the gear 24 is actuated by the segment 23 and engages therewith, it being understood that as soon as the segment has released the teeth of the said gear 24 weight or gravity returns the part roller 27 into the position shown in Fig. 2 in order to take another charge of ink.

, 29 designates a roller cut-off or cleaner for the inking means, said roller cut-off being adjustable in the frame 30 by the set-screw 31 in order that it can be made to accommodate different-size inking means, it being understood that the part roller 27 contacts with the roller cut-off before coming in contact with the die 28, so that any surplus of ink will be removed from the said part roller. After inking of the die as customary it is necessary to wipe the same, and I have provided a stationary wiper, which consists of the frame 32, suitably mounted on the frame 1 of the machine, having a cushion 33 thereon supported by springs 34, suitably mounted in the frame 32, while carried by the cushion 33 are the guides 35 for the die-holder, which serves to hold the same in proper alinement when passing therebetween, it being understood that said die-holder 17 is moving in a horizontal direction when the die is being wiped in order that the face thereof may be wiped evenly, said horizontal movement being insured by the flattened portion 20 of the track 18 and said guides 35 serving to retain the die-holder in proper alinement.

In order to provide suitable material for the wiping, I employ a roller 36, mounted in a suitable frame 37, carried by the bed or frame 1 of the machine, and mounted on said roller 36 is the material 38, which may be of paper or any other suitable material, said paper 38 passing over the cushion 33 and between the positive feed-roll 39 and the tension-roll 40, being adapted to be taken up upon the roll 41, which is likewise supported. The feed-roll 39 carries a ratchet 42, which is engaged by a spring-actuated pawl 43, car ried by the gear 45, and by a locking-pawl 44, the latter serving to hold the ratchet 42 and positive feed-roll after it has been suitably actuated, while said pawl 43 serves to rotate said feed roll when properly actuated. Mounted on said feed-roll 39 is said gear 45, which is in mesh with the teeth of a rack-gear 46, which is carried on the shaft 47, the latter being pivotally mounted upon a pin 48, which projects through a suitable slot in the rotary arm 15, and has a head 49 thereon engaging with the inner walls of said slot in order that the pins may be held in various adjusted positions in said slot, a suitable nut 50 being operated to accomplish this purpose. It will thus be seen that as the rotary arm 15 moves it carries with it the pin 48 and the shaft 47, which thus acts to rotate the gear 45, so that when the said rack is raised after the wiping has taken place it tends to throw the gear 45 in the direction indicated by the arrow in Fig. 3, which causes the pawl 43 to rotate same, the lockin pawl 44 riding freely over the teeth of the ratchet 42. When the shaft 47 islowered, and with it the rack 46, the pawl which is carried on the gear 45 rides freely over the ratchet 42, and no motion is imparted to the feed-roll 39, the effect of which is evident.

In order to actuate the take-up roll 41, I

have mounted upon the feed-roll 39 a pulley 51, upon which is mounted a belt 52, which passes around the pulley 54, mounted on the shaft 55, which carries the take-up roll 41, so that when said pulley 51 is rotated the takeup roll 41 is likewise rotated. The tensionroll 40 can be adjusted in its position in the frame 56 by means of a set-screw 57, so that a different amount of tension can be applied to the wiping material, as may be desired or necessary, in order to move the same.

58 designates an idler which is adapted to bear upon the rack-gear 46 in order to hold the same in mesh with the gear 45.

In the drawings, 59 designates a counter die or platen, which is carried by a counterblock 60, secured to the plunger 61, which reciprocates in a suitable portion of the frame 1 of the machine. Connected with the plunger 61 is one arm 62 of a pull-toggle, which is pivoted at 63 to the other arm 64 of said pull-toggle, the latter being again pivotally connected with the screw 65, on which is mounted a hand-wheel 66 in order to operate said screw, which latter is mounted in a suitable part of the frame 1 of the machine and is locked in its adjusted position by the jam-nut 67. Connected with said arms 62 and 64 of the pull-toggle at a point adjacent the pin 63 is a link 68, the other end of said link being pivotally connected by a bell-crank 69, which is pivoted at 70 to a suitable portion of the frame 1 of the machine, the other arm having pivoted thereto an end of a yoke-lever 71, which latter is provided with a yoke 72 at its lower end, which surrounds the shaft 9 of the machine. Carried on said yoke-lever 71 is a stud or roller 73, which is engaged by the cam 74, suitably mounted on the shaft 9, whereby it will be seen that said yoke-lever is oscillated and imparts motion to the bellcrank in order to actuate the toggle, and with it the counter-block 60 and counter-die 59, it being seen that when the impression is taken the link 68 pulls upon the toggle, whereby a greater amount of strength is provided with less weight of material than in machines of this character.

In order to lock the die 28 in position during the taking of the impression, I provide alock ing device which consists of a pin 75, which is preferablyprovided with a beveled end 76,

which enters a suitably formed recess in. the dieholder or chuck 17, said pin 75 being actuated by a spring 77, which tends to throw the same into its locking position. The opposite end of said pin 75 is suitably connected with one arm of the bell-crank 78,

v in the present instance by a link 79, said bellcrank being pivotally mounted upon a suitable portion of the frame 1 of the machine and having an arm 80, which is adapted to be struck 'at the roper time by a roller 81, car ried on the yo elever 71, in order that when said yoke rises it will strike the arm 80, removing the pin 75 from the die holder or chuck. If desired, I may provide a guard 82, which may be secured to any suitable part of the machine and which is adapted to project over the segment 23 in order to prevent the paper, which may be indicated as 83, from coming in contact with said segment.

The operation will be readily understood. Motion is imparted to the drive-pulley 3, and when the clutch 4 is properly actuated it will cause the drive-shaft 2 to rotate, it of course being understood that I may dispense with the clutch mechanism and have a mounted pulley with means for shifting a belt from one pulley to the other, so that when the shaft 2 is actuated it causes the gear 7 to rotate, which imparts motion to the gear 8, which rotates the shaft 9 and with it the mutilated gear 10, which is placed in position to mesh with the die drive-gear 13. When the teeth of said gears 10 and 13 are in mesh, the gear 13 is rotated and rotates the shaft 14, which carries with it the rotary arm 15, sliding carrier 16, die-holder 17 and with it the die 28, the plunger 61 meanwhile having been raised, as will be hereinafter described. The die-holder 17 passes around the track 18, and in its passage the segment 23 is caused to engage with the gear 24, which rotates the part roller 27, which previously has taken a supply of ink from the ink-fountain 26, the surplus ink being removed by the roller cut-off 29 and the part roller contacts with the die 28 and inks the same. In its continued movement the die is brought in contact with the wiping material 38 and evenly wiped as it passes over the same, as before described, in a horizontal line, the guides 35 and the springs 22 and 23 serving to hold the die-holder 17 in proper position relative to the track 18. As soon as the segment has released the gear 24 the roller returns to its former position for taking on another charge of ink. During the revolution and movement of the arm 15 the shaft 47 is carried therewith, which causes the rack-gear 46 to actuate the feeding-roller 39 at the proper time-that is, after the wipingin order that the wiped material 38 is caused to move a sufficient distance with respect to the cushion 33, and a clean surface is presented ready for the next wiping, the used material being taken up upon the roll 41, which is suitably actuated. When the die holder 17 has reached the upper face 19 of the track 18, the same is in position for the impression, and as soon as it is in this position the locking pin or wedge enters the recess therein and positively holds the die-holder 17. At the same time the mutilated portion of the gear 10 is opposite gear 13, so that no motion is imparted to the latter. When the parts are in the position for the impression, the yoke-lever 71 is brought to its lowermost position, thus causing the link 68 to pull upon the toggle- arms 62 and 64 forcing down the plunger 61, making an impression, it being understood that this action is caused by the stud or roll 73 being actuated by the cam 74. As soon as the impression is made the yokelever 71 is caused to be elevated, which brings the roller 81 in contact with the arm of the bell-crank, which pulls upon the pin 75 against the action of the spring 77 and removes the pin from the die-holder 17, the teeth of the mutilated gear 10 being so timed that they are brought again into mesh with the gear 13 and the die-holder, and these are again rotated. At the same time by the upward movement of the yoke-lever 71 the tog gle-lever and arms 62 and 64 are forced out, raising the plunger 61. From the above description it is seen that I have made an improved construction in embossing-presses, and'it will be further noted that said presses can be used for plain embossing by loosening the set-screw 12 and moving out the mutilated gear 10 in order that same cannot engage with the gear 13 so that the die-holder will be held in position on the face 19 and with it the die, since no motion will be imparted to the shaft 14, and the ordinary plain embossing may be accomplished, as will be seen.

It will be evident that various changes may be made by those skilled in the art which may come within the scope of my invention, and I do not, therefore, desire to be limited in every instance to the exact con struction herein shown and described.

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