To all whom it may concern.-

, complish these objects by the device shown in the accompanying drawings, in which? Figure 1 is a front elevation of an attachment constructed according tomy invention and applied to an embossing-press. Fig. 2 is a top plan of same. Fig. 3 is a front elevation showing in detail the parts which support and operate the die-carrying arm, the crank and die-carrying arm being turned toward the front and shown in section. Fig. 4 is a side elevation of the rolls for carrying the paper and the support for said rolls. Fig. 5 is a front elevation of the upper roll and its connections shown in Fig. 4. Fig. 6 is an enlarged side elevation illustrating the construction permitting the adjustment of the platform 19.

In the device shown the embossing-press and attachment are secured to a table-top 1. The supports for the table are not shown in the drawings. The standard 2 is secured to the table-top and carries the bearings 3 and 4, in which the shaft 5 is journaled. The crank 6 is feathered upon the upper end of the shaft 5, and the arm 7 is rigidly secured to said shaft below the bearing 3, so that said arm has a vertical movement with the shaft, while the crank is kept at a convenient height. The arm 7 isnormally held in its upward position on the shaft 5 by means of the spring 8, acting between the bearing4 and the shoulder 9 on said arm. A sector 10 is secured to the lower end of the shaft 5 and is provided with a groove 11 for the cord 12, which operates Serial No. 170,594. (No model.)

the roll 13 for winding up the strip of paper 14, which is used for wiping the die 15. The

die 15 is secured to the block 16, which is held on the under surface of the arm 7 by means of the members 17 and 18, which are screwed to said arm. The paper 14 is held in position to wipe the surface of the die 15 by means of the adjustable platform 19. Said platform is supported above an extension 20 of the standard 2. The platform 19 is supported directly upon a subplatform 21, which has a depending extension 22 slidably seated in the member 23, which projects upwardly from the extension 20. The height of the subplatform 21 is regulated by means. of a set-screw 24. The platform 19 is held to the proper level lengthwise of the arm 7 by means of the set-screws 25, said platform being tilted on a rod or pin 26. The cord 12 passes through sheaves 27, 28, 29, and and has a weight 31 secured to its end. Said weight holds the cord '12 at a sufficient tension on the shaft 29 so that when said cord is pulled by means of the sector 10 the sheave 29, .with the ratchet-wheel 36 and the roll 13, will be turned, so as to wind the paper 14 upon said roll, and thereby advance same over the platform 19. The paper 14 is unwound from the roll 32, the tension of which is regulated by means of the spring 33 and thumb-screw 34. The sheave 29, roll 13, and ratchet-wheel 36 are loose on the shaft 35, which is rigidly secured to the bracket 37 The roll 13 and ratchet-wheel 36 are connected by means of a collar or hub 38 on the ratchet-wheel, which is keyed to the roll 13. The pawl 39 is pivoted to the bracket 37 at 40. The pawl 41 is pivoted to the sheave 29 at 42 and has a spring 43 secured to said sheave, which normally holds said pawl in engagement with the ratchet-wheel 36. A plate 44 in the form of a sector is mounted on'the shaft and adjustable along its slot 45 on the pin 46, which projects from said slot and is seated in the bracket 37. The head 47 of said pin is tightened against the plate 44 by means of the thumb-screw 48. Said plate is provided with a flange 49, which projects in the path of the pawl 43, so as to prevent the engagement with the ratchet-wheel 36 until said pawl has passed the end of said flange. This provides for an adjustment which will limit the action of said pawl upon the ratchetwheel, so as to limit the amount of paper to be wound upon the roll 13 at each swing of the sector 10. hen the paper is first being wound upon the roll 13, it will be necessary to have the pawl 41 engage the ratchet-wheel 36 at a position to the right of that shown in Fig. 5, so as to turn the roll 13 far enough to pull the paper about the length of the platform 19. After considerable paper has been wound upon the roll 13, the circumference then being greater than before, the plate may be adjusted toward the position shown in Fig. 5, so that the ratchet-wheel will not be moved by the pawl as far as at first described. The increased circumference of the roll of paper upon the roll 13 will still cause the paper to be drawn a sufiicient distance over the platform 19 without moving the ratchet-wheel 35 through as great an arc.

An inking device is secured to the table 1 in the path of the arm 7 in suitable position to have contact with the die 15 before same is wiped by the paper on the platform 19. Said inking device consists of a receptacle 50, having journaled therein an inking-roll 51 and a regulating-roll 52, bearing against the inking roll. A flexible scraper 53, which may be made of rubber, is secured above the trough 54, which is supported on the lever 55 and fulcrumed to the base of the inking-receptacle at 56. The spring 57 normally raises the scraper 53, and its upward position is controlled by the set-screw 58 acting under the lever 55. A receptacle 59 is provided for collecting the drip of ink from the trough 54.

Above the hub 60 of the arm 7 is journalcd a cam 61, provided with a depending shoulder 62, arranged to act against the pins 63 and 64,- which are rigid on the upper part ofsaid hub. The washer 65 has rigidly secured thereto the pins 66, which pass through suitable apertures in the bearing 3 and are normally held in the position shown by means of the springs 67. A shoulder 68 is provided on the under surface of the bearing 3 for coacting with the shoulder 69 and the cams 61 when said cam is turned by means of contact of the pin 64 with the depending shoulder 62.

The operation of the device is as follows: WVhen the crank 6 is turned toward the right of Fig. 1, so as to bring the die 15 toward the inking-roller 51, the pin 64 will be brought 'in cont-act with the shoulder 62, so as to cause the hub 60 with its arm 7 to be depressed against the action of the spring 5, and there by bring the die 15 into contact with the inking-roller 51. In being moved toward the right of Fig. 1 the die 15 passes free from the paper on the platform 19, since the cam 61 is then in the raised position shown in Fig. 3. When the crank 6 has been turned far enough so as to bring the pin 64 into contact with the shoulder 62, the hub 60 will be depressed, as before mentioned. When the crank 6 is now turned toward the front of Fig. 1, the cam 61 will act so as to depress the hub 60 until the die 15 has been carried over and in contact with the paper on the platform 19. After the die has passed said platform as the crank 6 is moved farther toward the embossing-press 7 O the pin 63 on the hub 60 will come in contact with the shoulder 62, and thus move the cam back to the raised position in which same is shown in Figs. 3 and 1. The arm 7 is now at a suitable height to carry the die 15 in proper position into the embossing-press 70 and under the plunger 71. When said plunger is now moved downward in the action of the embossing-press, the arm 7 and its hub 60 will move downward against the action of the spring 5; but the cam 61 will be retained in the position shown in Fig. 3 through the action of the washer 65 and its springs 67. While the die 15 is being carried from the inker toward the embossing-press the same will be in the lower position through the action of the cam 61 and will then be brought in contact with the paper 14 on the platform 19, so as to be wiped thereby. After the die has been wiped the cam 61 permits the arm 7 to assume the raised position shown in Fig. 1. When the arm 7 is again moved out of the embossing-press by turning the crank 6, the sector 10 will act on the paper, as before described, so as to bring a new part of the paper in suitable position on the platform 19 to again wipe the die upon its return from the inker. Since the arm 7 is in its raised position when passing from the embossing-press toward the inker, the die will be free from the paper during the movement of said paper through the action of the sector 10. The stop 72 limits the movement of the arm 7 to the proper position in the embossingpress. The springs 73 hold the small roller 52 in contact with the inking-roller 51. The scraper 53 with its trough 54 may be adjusted to any desired angle on the arm 55 by means of the set-screw 74. The collars 75 are adjustable on the rods 76, which are secured to the standard, said collars serving as guides for the wiping-strip 14 to lead same properly from the platform 19. The upper surface of the platform 19 is covered with a resilient pad 77, which serves as a cushion under the wiping-strip 14. The weight 31 also serves to urge the arm 7 against the stop 72. The spring 8, being secured to the hub 60 and to the bearing 4, has a similar effect in urging the arm 7 against said stop 72.
