PRINTING PRESS ATTAGHMENT Application filed April 29 My invention relates to new and usefulimprovements in an attachment for presses and so far as the subject matter iscommon' is a continuation of my copending application filed May 9, 1924, Serial No. 712,020.

The principal object of the invention consists in the provision of an attachment for presses adapted to feed cardsorthe like, such as visiting cards, in proper position relative to the printing, stampingor embossing mech anism to receive the impression, said attachment including a rotatable table which successively positions the cards tothe im pressin mechanism and means for adjusting the table relative to the impressing mechanisnnthe table being rota-ted intermittently through certain mechanism which is operated from the power mechanism of the press.

Another object resides. in the provision of means for insuring the proper rotation. of, the table. to position the cards or the like beneath the impressing mechanism and. for holding the table in said position during the impressing operation.

A further object consists in the provision of a support for the rotatable table which includes means for adjusting the table transversely of the press and towards or away from the impressing mechanism.

WVith the above and other objects in view, which will appear as the description pro-. ceeds, my invention consists in the novel details of construction, and arrangement of parts, described in the following specification and illustrated in the accompanying drawings, and while I have illustrated and described the preferred embodiments of the invention, as they now appear to me, it will be understood that such changes may be made as will fall within the scope of the appended claims.

In the drawings 1 and 2 indicate sections of the press frame which are adapted to support the table sections 3, 4 and 5, the section 5 being shown in dotted lines and being removable to position my improved form of attachment when desired. The inner faces of the framesections land 2 are spaced apart as more clearly; illustrated in Figs. 1 and2 of the drawings and secured to the inner face of the frame section 1 isthe L-shaped bracket 6 and secured to the inner face of the-section 2 is the L-shaped bracket 7 The bracket 6 is secured tothe section 1 by means of the bolts 8 or other suitable fastenings while the bracket 7 is secured to the section 2 by means ofthe bolts 9 or other suitable fastenings. The bracket 6 is provided in its horizontal portion with an opening 10, and extending through this opening is a boltor'screw 11 asmore particularly illustrated in Fig. 7 of the drawings, an interiorly threaded cap or nut 12 being received on the screw or bolt for a purpose which will presently be brought out. Formed on, the. horizontal portion of thebracket? is an inverted V-shaped flange. or projection, 13 and supported on the bracket:

- or away from the impressing mechanism to. be later described. VVhen it is desired to ad- 7, adjacent the inverted V-shaped projection or flange 13, by means of the standards 14 is a rotatable horizontal shaft 15 formed with the worm gear 16 and the finger hold or knob 17 as shown more particularly in Fig. 12 of the drawings.

Supported by the brackets 6 and 7 is a frame denoted generally at a this frame including the ends 18 and 19 and the side rails 20 and 21, the upper edges of the side rails 20 and 21 being of inverted .V-shape as shown more particularly in Figs. 10 and 12 of the drawings. Formed on the end 18 is the outwardly extending flange .22 which is provided with the elongated opening 23 as shown more particularly in Figs. 2 and 4 of the drawings, the bolt or screw 11 carried by the bracket 6 extending through this elongated opening and the cap or nut 12 being adapted to engage the upper face of the extension as shown in Fig. 7. The end 19 of the frame is provided on thebottom surface with the inverted V-shaped groove or recess 24 to receive the inverted V-shaped flange or projection 13 formed on the bracket 7. A screw or bolt 25 extends through the flange or projection 13 of the bracket 7 and through an elongated opening 26 formed in the end 19. A nut 27 may be received upon the bolt or screw 25 to engage the upper surface of the end 19 as shown more particularly in Figs. 7' and9 of the drawings, and this nut is preferably provided with a handle 28 whereby the nut may be forced into tight engagement with the end of the frame. The worm gear 16 on the rotatable shaft 15 is adapted to engage in vertically extending recesses 29 formed in the out er face of the end 19 as shown more particularly in Fig. 12 of the drawings. It will be seen that the frame a may be adj usted longitudinally of the brackets 6 and 7 or towards just the frame the cap ornut 12 and the nut 27 will be released. Then by rotating the rod 15 and its assoeiatedworm, gear 16. the frame:

will he moved to the desiredposition, it being understood, as previously stated, that the worm gear 16 will engage in the recesses 29 onthe outer face of the end 19 of the frame.

When positioned as desired the cap or nut 12 and the nut 27 will be again adjusted or tight ened to hold the, frame in its adjusted position against accidental displacement.- Formed on the'up'per edge of the side rail 20 of the frame a, intermediate the ends there 30 for a purpose to be the frame a is the baseor table 31 which'has formed at each cornerthereof a lug or projection 32 having'an opening therein of a,

shape corresponding to a transverse section of the side rails 20 and 21, the side rails 20 and 21 passing through the openings, in,

aligned lugs or projections. Extending outwardly from the forward edge of the base or table 31 is a rotatable shaft 33 to which is secured a gear wheel 34 adapted to mesh with the rack 30 formed on the upper edge of the side rail 20. Formed on the outer end of the shaft 33is the knob or handhold 35 which is grasped for rotating the shaft and its associated gear wheel and by the rotation of the gear wheel, which as previously stated, meshes with the rack 30, the base or table will be moved longitudinally of the frame into the desired position. The base or table will be held against accidental movement by means of the thumb screw 36, shown more particularly in Fig. 10 of the drawings, which engages the bottom surface of the side rail 20. It will be understood that this thumb screw will necessarily have to be released when the base or table is to be moved in the manner previously described.

The base or table 31 is formed with the vertically extending central opening in which the sleeve 37 is adapted to be rotatably mounted. Formed on ,or secured to "the upper end of the sleeve is the disc 38 which is provided with the substantially V-shaped recesses 39 initsouter edge as shown more particularly in Fig. 4 of the drawings and for a purpose to be later more clearly brought out. Secured to or formed on the lower end of the sleeve 37 is the ratchet wheel 40 which is adapted to be engaged by the pawl 41 pivotally connected at 42 to one end of a lever 43 which is pivotally supported by the bracket 44 as more particularly illustrated in Fig. 5 of the drawings. A coiled spring 45 is connected at one end to the bracket 44 and at its opposite end to the pawl 41 to normally hold the pawl in engagement with the ratchet wheel 40.

Formed in the upper face of the base or table 31, adjacent one end thereof, and extending from the forward edge is the recess 46. Extending longitudinally of this recess 46 is the adjusting screw 47 being formed adjacent its outer end with the collar 48 received in the vertically extending grooves 49 adjacent the'forwa'rd end of the-recess 46. .The adjusting screw is also formed at its outer end with a finger hold 50 whereby the screw may be rotated when desired. Slidably mounted on the upper surface of the base or table 31 is the-block 51 having the depending portion 52 which extends into the recess 46. This depending portion 52 is provided with a horizontally threaded opening through which the adjusting screw 47 will pass as more particularly illustrated in Fig. 13 of the drawings. The block 51 is provided on one side face with the flange 53 provided with the elongated opening 54 through which extends a screw or bolt 55 as shown more particularly in Fig 7 of the drawings, this bolt or screw being received in the base or table 31 and a handheld or lever 56 being formed on'the and thetop surface of the flange 53. -VVhen the bolt or screw is released the block 51 may be adjusted longitudinally of the recess 46 by means of the adjusting screw 47. WVhen adjusted to the desired position the bolt or screw 55 will be again tightened. Pivotally connected at 58 to the block 51 is the pawl 59 the outer or free end of which is adapted to engage in the notches 39 formed in the plate 38 as shown more particularly in Fig.

:1 4 of the drawings. A coiled spring 60 is interposed between one face of the block 51 and one face of the pawl 59 to normally urge the free end of the pawl outwardly for e11- gagement with the disc 38 or in one of the notches 39 thereof. The block 51 and its associated pawl are adapted for properly positioning the sleeve 37 and holding the same to in turn properly position the card supporting table, to be later described, relative to the impressing mechanism.

The card supporting table is shown at 61 and is formed with the arms or wings 62 on each of which is adapted to be held a card 63 as shown more particularly in Fig. 2 of the drawings; Each of the arms or wings has a spring finger 64 which engages the card as shown and gauge blocks 65 position the cards relative to the fingers. The table Gliscarried by the vertically extending shaft of the links or bars 74 and 77 swings the 66 which extends into the rotatable sleeve 37 carried by the base or table 31. The shaft is shown as provided with a flattened surface.

' I shaft 67 of the press which has the eccentric i '-is swiveled to the base of the press. Pivot ally connected at 7 3 to the upper end of the lever 7 2 is a bar or link 7 having thethreaded end 75 to receive the turn buckle 76. The turn buckle 76 connects the bar or link 74 -to the bar or link 77 having the threaded end 7 8, the opposite end of the bar or link 77 being pivotally connected at 79 to the lever 43. It will be seen that as the drive shaft 67 rotates it through means of the bar swings the lever 7 2 which through means lever43 which in turn through means of the pawl 41 rotates the sleeve 37 and the table 61 in a step by step movement. The sleeve will be rotated in one direction at all times and is held against reverse movement by means of the pawl 59 which engages in one of the notches 39 of the disc 38. The turn buckle 7 6 allows for adjustment between the links or bars 7 4 and 77 to allow for the movement of the frame a and the parts carried thereby towards or'away from the impressing mechanism.

At 80 I have illustrated generally a reciprocating plunger which is of the form now commonly used upon presses for making an impression and as the plunger forms no part of my invention a detailed description thereof is not necessary. The plunger is operated through means of the frame 81 which has the depending arms 82 connected to the eccentric pin 68 of the drive shaft 67, the plunger being lowered for making an impression upon the lowering of the frame 81 and returning to its raised or normal position when the frame is raised. An opening is formed adjacent the lower end of each of the depending arms and the eccentric pins are received in the openings.

The impression for printing or engraving the card is taken from the plate 83 which is carried by a plate holder 84 which is supported in a sliding table or frame indicated generally at 85. The table or frame 85 is adapted toibe reciprocated so as to draw the plate beneath the inking mechanism, not shown, and to then position the same beneath the card. A rod 86 is secured to the frame or table 85 and will be operated through means of suitable mechanism connected to the driving shaft of the press such as by a link or rod 87. r t

From the above detailed description it is thought that the construction and operation will be clearly understood and it will be noted that I have provided novel mechanism for using the well-known forms of printing presses for printing visiting cards or the like, the cards'being fed by a step by step niovement into position to receive the impression from the printing mechanism. -There being three arms to the rotatable table, as one card is receiving the impression that card which has previouslyreceived the impression is be-' ing removed by the operator and another card is being placed in position. The table is intermittently rotated by the pawl and ratchet mechanism] and the rotation will be so timed as to have the cards fed into position to receive the impression at the time that theplunger is in raised position and the plate holder or carriage is in its rearwardmost position being inked. After the card has been properly positioned the plate holder or car riage is fed to a position beneath the card and then the plunger is lowered and the impression made. In the present application the rotatable table is so supported or mounted that it may b-e adjusted relative to the printing or impression plunger so as to accomnios date cards of different sizes, difierent shapes,

5 transversely of the press. When it is desired.

to adjust the table towards or away from the impressing plunger the nut or cap 12 and the nut 27 will first be released and then the rod 15, shown more particularly in Fig. 12 of the drawings, is rotated. As the worm gear 16 engages in the recesses 29 this will slide the frame on the brackets 6 and 7 towards or away from the impressing plunger. When the desired position is reached the nut or cap 12 and the nut 27 are again tightened. hen it is desired to adjust the table transversely of the press the thumb screw 36 is released and then by rotating the rod or shaft 33 the table or base 31 will be moved longitudinally of the frame a by means of the gear wheel 3:4: engaging the rack 30. hen in its desired adjusted position the thumb screw 36 will be again tightened. I also wish to lay particu lar advantage upon the provision of the slidable block 51 and its associated pawl 5-9 which engages with the disc 38 and more particularly the notches 39 therein. The pawl .causes a definite positioning of the'sleeve 3'7 and the table carried thereby upon each operation and turning of the sleeve and by the use of this pawl it is not absolutely necessary that the sleeve be in its correct posit-ion after being rotated by the lever 43. If the sleeve is rotated a sufficient distance for the end of the pawl 59 to engage with the wall of a notch 39 the coiled spring exerting strong pressure on the pawl will cause the free end thereof to ride into the notch and to minutely adjust or rotate the sleeve. By turning the adjusting screw 47 the lock 51 may be adjusted to slightly change the position of the pawl to secure the proper adjustment. This at times will allow the feed table to be rotated into the press at an angle in order to make correct register of the card in the event that the impression plate is not properly engraved. At the same time the pawl 59 will hold the sleeve in its adjusted position, against accidental displacement, until another operation takes place by the swinging of the lever 43.

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

1. In combination with a printing press, a rotatable table, and means for adjusting the table to either side of the press.

2. In combination with a printing press, av rotatable table, and means for adjusting the table towards or away from the press or to either side thereof.
