JOSEPH H. SWVIFT, OF BROOKLYN, NEW YORK.

MACHINE FOR PRINTING BOXES.

SPECIFICATION forming part of Letters Patent No. 368,253, dated August 16, 1887.

Application filed December 4, 1886. Serial No. 220,693. (No model.)

To all whom it DMZZ/ concern.-

Be it known that I, JosEPn H. SWIFT, a citizen of the United States, residing at the city of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machines for Printing Boxes, of which the following is a specification, reference being had to the accompanying drawings.

The invention relates to a machine for printing labels upon packing-boxes and the like; and it consists in the special improvements hereinafter designated.

In the accoi'npanying drawings, Figure 1 represents a plan of the machine; Fig. 2, a plan of the device used for adjusting the position of the ink-distributing rollerf; Fig. 3, a plan of the device used in holding the ink-distributing roller 0 in position; Fig. 4, an elevation of the rear of the machine; Fig. 5, .a plan of the mechanism used in operating the box-forwarder 1; Fig. 6, a central sectional view of the box-forwarder g/ and its connecting parts; Fig. 7, a side elevation of the machine; Fig. 8, a vertical section showing means for adjusting the position of the shaft Z, which supports the type-cylinder 7. Fig. 9, a vertical section (in part) of the shaft Z, which supports the type-cylinder k, showing the heads 1' s of the latter and the means for adjusting and holding the same in position; Fig. 10, a vertical section of the lower portion of one of the ink-wells, showing the outlets for the ink.

In the practice of my invention a suitable frame, a, is provided, upon which are supported the various parts of the machine.

The machine is set in motion by means of power communicated through a fixed pulley, b, on the shaft 0, Fig. 4. The shaft 0 is provided with a beveled pinion, (Z, by means of which motion is communicated to the beveled gear-wheel c, secured to the shaft f, the latter shaft, f, also having secured to it at the upper end a pinion, g, Fig. 7, by which motion is given to the gear-wheel h on shaft i, Fig. 4. The shaft 1' has secured to it a cylinder, j, which is arranged on one side of the frame, substantially as shown in Figs. 4 and 7. On the other side of the frame is a similar cylinder, 7;, the same being secured to the shaft Z, to which latter shaft motion is imparted through the gear-wheels h m and the loose pinions n 0, Fig. 4 the gearing being so constructed and arranged as to cause the shafts i and Z to opcrate simultaneously and at the same rate of speed, but in different directions axially. Rubber or other suitable type, 12, for printing the desired labels are secured in any suitable manner to the periphery of the cylinders j and k. In Fig. 7 the type-plates q q are represented as held in position between the flanged heads '1' s of the cylinder k.

In order to adapt the machine for use in printing boxes of different widths, it is necessary to adjust the position of one of the cylin ders, so as to bring them closer together or place them farther apart, as may be required. Slots 15 t are made in the frame a, so as to allow of such adjustment, the form of such slots being shown in Figs. 7 and S. The shaft Zis provided with adjustable bearings 10 u, as

shown in Figs. 7 and 8', which are moved along flanges or ways 1) '0 by means of the handscrews w w,the latterbeing supported in flanges w By adjusting the position of the bearings 10 u, as described, the position of the shaft Z, with its supported cylinder is, is likewise adj usted, there being sufficient play in the gearing to allow of some adjustment. In cases where the play in the gearing is not sufficient to allow of the desired adjustment, pinions of less diameter may be substituted for the pinions 0., The shafts i Z are held in place by means of collars y y, or in any other suitable manner.

In printing boxes of different heights typeplatcs of differcntlengths are used, and it therefore becomes necessary to adjust the position of the cylinder-headsrs. The upper cylinderhead, which slides upon the shaft, may be secured in any desired position by means of the nuts .2, which co-operate with the thread out upon the shaft Z, as shown in Figs. 8 and 9. The lower cylinder-head is held in any desired position by the cooperation of its own thread with that out upon the shaft, as well as by the thumb-screw a, which passes through the collar Z).

' On each side of the frame is provided an ink-well, 0, provided with a vent-pipe, c, and funnel (Z, substantially as shown in Figs. 4c and 7, the ink being supplied to the typcp through the intermediate rollers, d e f, there being a set of such rollers on each side of the frame and in connection with each ink-well. These ink-distributing rollers are coated or covered with gelatine in the usual manner. The flow of the ink from the wells 0 0 through the orifices g 9' (shown in Fig. 10) is regulated by loosening or tightening the screws or plugs h h. The rollers are similarly arranged and similarly operate on both sides of the machine. The roller d is caused to reciprocate back and forth in contact with an ink-well by means of pitmen 11 77, which at one end connect with the axis of the roller and at the other end are eccentrically pivoted to either the shaftt' or Z, substantially as shown in Fig. 1. The roller d is caused to intermittently rotate by frictional contact with the roller 8, theaxis of the former being freeto revolve in the ends of the pitmen ii. An up-and-down motion is given to the roller e by means of the cooperation of the cam j on the axis of the roller f with the collar is on the axis of the roller 6, substantially as shown in Fig. 7. The roller f is caused to revolve by means of -the pinion Z, which is secured to the axis of the roller, and to which motion is given by the gear-wheel m on shaft 1.

Asshown in Fig. 1, the frame a is provided with slots n a, through which the upper ends of the axes of the ink-distributing rollers pass. Provision is thus made in conjunction with similar slots which are provided in the frame to receive the lower ends of such axes for the adjustment of the rollers and for the reciprocation of roller d. The roller (1 is held in position by means of the collars 0 0, Fig. 7, or in any other suitable manner. The roller 6', as shown, is upheld by means of the collar and cam j. The position of the roller f is adjusted by means of two devices of the pattern shown in Fig. 2. This device consists of the hand-lever p, pivoted to the frame a at the point marked q, and provided with a slot, 1", adapted to co-operate with the stud 8. These devices are placed in the positions shown in Figs. 1 and 7. The hand-lever p of the lower deviceis formed with a seat or step adapted to receive the lower end of the axis of the roller f, the latter being thereby or in any othersuitable manner upheld. The roller 0 is held in position against the roller f by means of two devices of the form shown in Fig. 3. These latter devices, which are placed in the positions shown in Figs. 1 and 7, consist in each case of a plate, a, secured to the frame a, and a thumb-screw, t, which screws intoand through the plate a, substantially as shown. Y

In the case of each of the pitmen i i the two portions of the same are connected by means of the coupling a, which is provided at one end with a right-hand screw-thread and at the other end with a left-hand screwthread, so as to co-operatewith suitable threads cut upon the ends of the divided pitmen, provision being thus made for lengthening or shortening the latter. The machine is also provided with a table, w, which extends out beyond the frame, as shown in Fig. 7. The table is provided with a slot or way,w, of

suitable form, Fig. 1, in which operates the box-forwarder y, the latter being a device for pushing or conveying the box into proper position to have the labels printed upon it.

The form of box-forwarder shown in Figs. 1 and 6 consists of a piece of metal adapted to slide in the way 00 and provided with a downwardly-projected portion, a, through which passes the rod a, the latter being secured thereto by means of a setscrew, a The forwarder is provided at its front end with a dog,

I), the latter being pivoted within a recess, substantially as shown in Figs. 1 and 5. The lower end of the dog, which isin the form of a fork,c, extends down through the way w,and in the'position shown loosely clutches the rod of, the latter having at that particular point a less diameter, substantially as shown in Fig. 6. As-

shown, the dog stands vertical, being so balanced as to naturally maintain that position. The box-forwarderyi, when placed in the way as, so far sinks therein as to allow for the necessary play and projection of the head of its sup- 7 ported dog b in the'operation of the machine.

The mechanism for operating the dog consists of the rods a a, the lever f and the link 9", Figs. 5, 6, and 7. I

The link 9 is pivoted at one end to the rod a and at the other end to the lever J, the opposite end of the lever f being pivoted to the frame a. The lever f is also pivoted at about its central portion to the rod e*, the other end of the latter rod being connected with the gear-wheel m, substantially as shown. In order to allowfor the adjustment of the cylinder k and the necessary lengthening or shortening of the rod f, the connection between the latter and the gearwheel at is made by means of a slot, f and screw-nut f the latter cooperating with a threaded pin on the end of the rod. Devices for guiding the box and for holding it in position are also preferably employed.

The frame of the machine is provided with two bars, h and 13?, Figs. 1 and 4, to which are secured two flexible strips of metal, j j, bent substantially as shown, so as torest upon the box and hold it down as it moves along the table.

Another spring. guide or holder, Fig. 4, is supported from the bar '6 the same being formed of the cross-bar 7c, rod 1", spiral spring m, and nut a. The nut n serves to hold the rod Z in position,and by means of it the height of the cross-bar 70 may be adjusted so as to render the guide capable of use in connection with boxes of different sizes. This latter spring-guide is of service after the box has passed beyond the strips 9" j. also provided with two hanging arms, 0 0, Figs. 1 and 4, to which are attachedtwo flexible metal strips, p 10, which serve tokeep the moving box in linewith reference to the type cylinders.

The arms 0 o are removable from the frame, longer or shorter ones being used, according to the different sizes of the boxes upon which,

The bar 1" is.

IIO

the labels are to be printed. The arms 0 0 are placed adjacent to the cross-bar k and so serve to keep it from swinging.

In operating the machine a box is first placed on the table '20 in front of the box-forwarder y, and the machine is then started. As the gear-wheel m turns the box-forwarder is drawn forward and the head of the dog, serving as a shonlder,pushes the box along the table until brought into position to be caught between the type-cylinders j k, by which latter the labels are printed upon the box. The gearing is so timed that the boxes as fast as they are brought forward shall be caught between the type on the cylinders j is, the labels being thusprinted on as the box passes through, and the cylinders turning in time to catch the next box. The boxforwarder is both drawn forward and pushed back during asingle revolution of the type-cylinders. In case there should be any boxes resting on the tablewhen the forwarder is pushed back, the head 'of the dog (the latter being loosely pivoted) would be forced down by the weight of the boxes to alevel with the top of the table, and so enabled to slide under the same. Suitable play for the lower end of the dog when its head is thus depressed is provided by making the rod c of less diameter at that point, as before set forth. After passing the boxes, the dog will assume its vertical position. The boxes may be supplied to the table by hand or by an automatic feeder. As the box is drawn along the table and passed between the type-cylinders it is held in position by the guiding devices before described. During the operation of the machine the set of ink-distributing rollers c ef on each side of the frame is of course kept in motion, the roller (2 being pushed back and forth in contact with the orificcsg g, and receiving ink therefrom to be distributed to the other rollers. The roller 6, which has an up-and-down motion, as described, takes the ink from the roller (2 and spreads it upon the roller f, from which latteritis again taken by the type on the cylinders j k.

In the practice of my invention the form of the machine or of its different parts admits of variations without change of character and without affecting the result to be accomplished, and I do not, therefore, limit myself to the exact forms shown and described.
