PBINTING ATTACHMENT FOB GO'UNTERSKIVING MACHINES.

Application mea January 11, 1924. semi No. 685,554.

To all whom it may concern:

Be it known that I, FRED D. MALAGUTI, a citizen of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented new and useful Im rovements in Printing Attachments for gounterskiving Machines, of which the following is a specification.

The object of the present invention is to v provide means in combination with a counter-skiving machine for rinting on the counter as it issues from t e machine after being skived. It is not important what the words or symbols imprinted on the counter may be, whether they indicate grades, sizes, qualities, or the makers name, or what not.

The important fact is that, as the skived,

' counters are delivered from the machine,

the desired'symbols or words, or other de* vices are printed upon them.

A further important feature of the invention is that a ment is couple with a part of the machine in-such manner that it is operated in a specific way and for a certain purpose, only when counters are assed through the feeding rolls of the sklving machine, and does notoperate when the counters are not fed,

even though said rolls and the printing device of the printing attachment may be in operation. These specified parts which:

are thus connected for joint operation are, in the embodiment of the invention here illustrated, the feeding pusher of the skiv-' machine, and the mk-distributing roller for the printing device. But within the scope of-the broad principles for which I seek protection, other parts of the mechanism may be similarly coupled and controlled one by the other.

The precise nature of the invention is more fully explained in the following specification in connection with the detailed description of one, form of machine embodying these principles, which machine is illustrated in the drawings provided herewith.

In such drawings,

Figure 1 is a front elevation of the ma chine referred to. v

Figure 2 is a plan view of the machine.

Figure 3 is a perspective view of the printing attachment.

Figure 4 is a vertical central section of the machine.

Figure 5 is a perspective view of the matrix roll, which is one of the pair of Cpart of the printing attachfeeding rolls for a counter blank, and con- In the drawin s, the numeral 10 represents the frame of a 8 Wing machine, which may be of any desired construction. 11 represents a matrix roll having a matrix or recess 12, of the character and. for the purpose known in the art. 13 represents a series of parallel disks cooperating with the matrix roll to feed the counter blank to a stationary skiving knife 14. For the purposes of this description, the disks 13 may be considered as collectively forming a feed roll complemental to the matrix roll. The matrix roll 11 is mounted on a shaft 15 and the disks 13 are similarly mounted on a shaft 16. These two shafts are geared together by intermeshing gear wheels 17 and 18, and the shaft 16 is driven by a gear 19 attached to it. Said gear receives power from a pinion 20 on a shaft 201, on which also are the belt pulleys 21 and 22. Between the disks 13 are arranged presser fingers 23, supported pivotally on a rod 24, and having arms 25. These arms are pulled upon by springs 26 in a manner to press the fingers 23 toward, the matrix roll, so as to distort and offset the counter blank into the matrix cavity of the roll, leaving only the edge parts of ,the blank so projecting as to be cut by the knife 14.

A magazlne for counter blanks to be skived is formed by a bracket or shelf27, on which are secured upright angle posts 28, to receive and position the ends of the counter blanks. To these posts are 'secured curved guards 29, which so far embrace the curved edges of the counter blanks near their ends as to retain the blanks in a pileon said shelf. The latter is attached to the side of the frame at about the level of the .tangent line beween the matrix roll and the complemental feed roll.

The guard or retaining means for the counter blanks, atthe end next tothe rolls,

is cut away above the shelf27. for-a distance,

equal to the thickness of a single blank, or enough gfeater than such thickness to permit the lank to pass through such space, but not enough to admit two. blanks at the same time. p

A pusher 30 is arranged to slideover the surface of the shelf 27 froin the outer part thereof toward the rolis, and it, has an edge shaped to conform with the outline of the counter blank, and in the plane of the lowermost blank, whereby it is adapted to en gage said blank and push it through the discharge opening 31 of the magazine to- Ward the rolls. This pusher has an arm 32 carrying a lug 33, to which is pivoted a link 34. The link is also ivoted to an arm 35, fastened to a rock-sha t 36, on which it is also secured to a second arm 37, carrying a roll which bears on the rim of the cam 38, on the shaft 16. A spring 381 engaged at one end with a fixedarm',.and at the opposite end with the arm 35, presses the roll of the arm 37 against the cam 38, so that the rotation of the cam reciprocates the pusher. Thus with each revolution of the rolls, the blank pusher is given a back and forth reciprocation in time to feed the lowermost blank of the pile to the shaft of the feed rolls, whenever the forward end of the matrix cavity is approaching the point of tan-- gency with the lower feed disks.

As the blank passes between the matrix roll and feed disks, it is brought against the edge of the lmife', and delivered above the knife, while the skivings fall upon .a deflector plate 39. From the knife the newl skived counter as shown by dotted lines at 1 (Figure 4), passes to a printing device, which consists of a printing roll 40, and an impression roll 41. The printing roll has types on its face, as shown in Figure 3, and is mounted on a shaft 42, rotating in bearings 43, said bearings being parts of brackets 44 and 44 which are secured to the frame of the skiving-machine. The impression roll in its turn, is mounted on a shaft 45, turning in bearings 46, which'are provided in parts of the skiving machine frame itself. These rolls, the printing and im' ession rolls, form a printing couple whic is an attachment to the machine. Not only are they the printing couple, but they also cooperate to grip and feed the counter, supplementing the action of the matrix roll and feedin disks, to draw the rear end of the counter past and awafrom the knife, after the counter has le the nip of the-matrix roll and disks. The impression roll 41 is driven for this purpose from the shaft 201, on

which the pinion 20 and pulleys 21 and 22 are also mounted, by a gear 202 on said shaft, and a gear 203 on the shaft 45.

With this aspect of the machine in view, the matrix roll and disks may be considered as the primary feeding means or couple of the combined machine and the printing couple may be considered as a secondary feeding means or couple, which combines the function of feeding with that of printing. For that purpose, the surface of the im ression roll is preferably fluted or ribbe as shown'best in Figure 3. The types of the printing roll in themselves, provide projections which cooperate with the impression roll to grip the counter.

It is to be understood of course, that the printing roll may be of any diameter and width of face, and may carry printing types of any descriptiomto impress any desired words or symbols. on the counter, provided only that the area of the roll which carries the printing device is sufficiently within the outlines of the counter.

The ink or color for printing is contained in a fount 47, on an arm 48, which is secured detachably to a bracket 49, said bracket in turn being detachably secured to. one of the brackets 44 previously described.-

y slide on a rod 56, which is mounted at one end in the bracket 44. These arms 55, 55, are spaced apart by the shaft on which the roller turns, and they are normallyheld in the position shown in Figure 3. The arm 55 is pushed toward a collar 57 by a spring 58 confined between the arm 55 and the collar 59 on rod 56. i

The carrying roll 52 is also free to turn and move endwise on its supporting rod 53, and is retained approximately in the position shown in Figure 3, by springs 60 and 60 which flank it and are confined by collars 61 and 62, respectively.

The arm 55 of the distributing-roll holder is connected by a chain 63, with one arm g ing 67, which encloses the gears 17 and 18,

and is in turn attached tow the adjacent end member of the skiving-machine frame. The said lever has a second arm which is connected by a chain 68, with a bell-crank lever 69, pivoted at 70 on the shelf 27, which forms the bottom of the counter-blank magazine. The other arm of this bell crank car ries a roll 71, which lies close to the supporting surface of this shelf, and in position to be engaged and displaced by the curved edge of the counter b ank when the latter is pushed toward the primary feeding thus causing the ink which is elivered in a narrow path to the roll 52, to be distributed fully over the faces of the printing de 'ce. By this action the counter blank, in ing fed to the skivin machine, renders the printing couple e ective to print upon it when it has passed the skiving point and advanced to the printing point.

I claim:

-1. In a counter-skiving machine, the combination of a. knife; primary feeding mechanism in advance of the knife, includin rolls adapted to grip a counter blank, an means for rotatingthe rolls to feed the blank to the knife; and counter-feeding and printing mechanism beyond the knife, including rolls adapted to grip the skived blank, one being a printing roll having types, and the other an impression roll, an means for driving the printing and impression rolls to cause the same to simultaneously print and continue the feeding of the skived blank.

2. A counter-skiving machine comprising a matrix roll, a complem'ental feeding roll, a magazine for'oounter blanks, means for feeding counter blanks successively from said ma azine to said rolls, a skiving knife past WhlCh the blank is forced by the propelling action of said rolls, a printing couple mounted as an attachment to said machine, and to which the counter sses its propelled progress from the s 'vin kmfe, and an ink distributing roll for de 'vering ink to the printing member of said couple, and means controlled by the blank-feeding means of the skiving machine for 'ving distrilllmting movements to said distributing ro a 3. The combination with a skiving machine, having complemental rolls adapted to grip and feed a blank to be skived, a knife arranged to skive the blank so fed, and a preliminary feeder intermittentl acting to deliver counter blanks to said ro a printing attachment in which the counter is delivered by said rolls after passing said knife, said attachment including a normally inoperative element, and mechanism actuated by the preliminarg feederwhenevera counter blank is fed t ereby, for making said element 0 erative in preparation for the arrival o the blank so fed to the printing attaehment.

In testimony whereof I have aflixed my signature.

FRED D. MALAGUTI.
