THOMAS HARPER, OF \VEHTOIIESTER, ASSIGNOR TO JOHN HARPER, OF BROOKLYN, NEW YORK.

PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 453,773, dated June 9, 1891.

Application filed August 20,1890. Serial No. 362,500. (No model.)

To aZl whom it may concern.-

Be it known that I, THOMAS HARPER, of \Vestchester, in the county of \Vestchester and State of New York, have invented a certain new and useful Improvement in Printing-Machines, of which the following is a specification.

This improvement is especially designed for successively printing upon articles having curved surfaces, such as lamp-shades, articles of sheet metal, and the like, but is applicable to the printing of [lat surfaces.

I will describe a machine embodying my improvement, and then point out the novel features in the claims.

In the accompanying drawings, Figure 1 is a top View of a machine embodying my improvement, with certain parts omitted and others represented in section. Fig. 2 is a vertical section or" the same, taken substantially at the plane of the dotted line as at, Fig. 1.

Fig. 13 is a side View of parts of modified construction for holding articles to be printed. Fig. 14. is atop View of the parts shown in Fig. 13.

Similar letters of reference designate corresponding parts in all the figures.

Before attemptinga detailed description of the parts comprised in the machine which I have illustrated I will attempt to give a general explanation of the principal parts and their movements and operations.

A designates a number of plates or beds forming supports for articles upon which printing is to be done. In the present in stance they are particularl y adapted for supporting glass lamp-shades. I have represen ted such a shade in dotted outline in Fig. 2. Combined with these supports A are holders B, which are intended to rest upon the articles to be printed and retain them upon.

the supports. It will be seen that the holders are in the present machine located above the supports. Theyare sustained byaframe which susceptible of a rotarymovement for the purpose of revolving the articles to be printed opposite toanumber of separate types supported by type-holders C, so that successive impressions may be made upon the articles to be printed. The supports A will preferably also be made capable of a rotary movement, so as to afford provision for presenting to the type different portions of the surfaces of articles to be printed. \Vhen this provision is made the holders B will be made capable of a similar movement. It will be also advantageous to render the supports A capable of adjustment up and down toward and away from the type, and at different angles to the horizontal, for in this way articles of different sizes and shapes may better be presented to the types.

The holders B will preferably be made adjustable toward and away from the supports A for the accommodation of articles of dilferent sizes. I

The ty pes used will have a flexible surface which may be flattened to facilitate inking, and nevertheless can be bent to conform to the curved surface of a convex article in printing.

The type-holders are arranged in a circular row, and are made capable of a reciprocating movement radially to the circle in which they are arranged to enable them to move to and from articles resting upon the supports A.

They are supported upon carriers D in such' manner as to admit of their being adjusted up and down and sidewise. They may also be adjusted longitudinally toward and from the supports A by varying the points of con.- nection between their carriers and rods which reciprocate the latter.

Combined with the type are inking-rollers E, inking-tables F, and appurtenances, whereby the inking-rollers may be caused to run over the inking-tables and afterward traverse the faces of the types.

Having now, as I think, fully explained the nature, movements, and operations of the principal parts of the machine illustrated in the drawings, I will describe these parts and their appurtenances in detail.

A designates a rotary frame with which the supports A are connected and by which they are revolved. This frame has a tubular hub a, which fits upon a tubular boss 0.

formed at the upper end of a standard A (See particularly Fig. 3.) This standard is fastened to a floor A or other suitable support, so as to be stationary.

To the frame A are attached a number of arms a To these arms blocks a are fitted in such manner as to be free to slide lengthwise of the arms and consequently toward and from the center of the frame A. Screws a having a bearing at the outer ends of the arms a and engaging with tapped holes in the sliding blocks a, afford provision for adjusting the blocks lengthwise of the arms. To the blocks a blocks a are fitted, so as to be capable of sliding vertically. Screws a ,having a bearing at the lower ends of the blocks a, and engaging with the tapped holes in the blocks a, afford provision for adjusting the blocks a vertically. The blocks a may be fitted to the arms a by means of dovetailed tenons and grooves and the blocks 0. may in the same manner be fitted to the blocks a. Not only do the screws a a afford provision for adjusting the blocks, but they also answer to hold the blocks in position. Arms a are pivotally connected by pins or screws a to the upper ends of the blocks a, and have formed in them concentrically with these pins arc-shaped slots at through which clampingscrews a pass, and after extending through the same enter tapped holes in the blocks a. This manner of connecting the arms a with the blocks a affords provision for adjusting these arms a at differentinclinaiions to the horizontal.

The arms a serve to sustain the plates forming the supports A. They therefore have cylindric bosses (L12 formed upon their upper sides, and the plates A have corresponding holes formed through them. The plates may be slipped over the bosses, and when this is done will be supported by circular flanges 0 which are located at the base of the bosses. The plates can be lifted off at any time. It is clear also that the plates may be rotated on the bosses either by applying the hand to them or through some suitable mechanism.

The arms a areprovided at their outer ends with slideways a, consisting of two parallel ribs projecting from one side. In these slideways fit the lower extremities of bent arms I), which are shown as vertically slotted at the portions fitting Within the slideways to receive clamping-screws b, that pass through them and engage with tapped holes formed in the backs of the slideways. The upper extremities of these arms I) extend toward the center line of the frame A. the centers of the bosses a they are provided with sockets N, which receive rods b having the holders B connected to their lower ends. Preferably theconnection will be made by circumferentially grooving the lower ends of the rods and inserting in the hubs of the holders l3 screws or pins which will enter the circumferential grooves. The rods 19 are intended to be capable of a longitudinal movement toward and from the supports A, and to the end that such movement may be easily imparted to them levers II are combined with them. These levers are fulcru med to lugs I), with which the arms I) are provided, and'at one end are pivotally connected by pins 1) with the rods 113, a sufiiciently loose connection being made to prevent the swinging of the lever from interfering with the described movement of the rods. The other ends of the levers form handles through which the levers may be oscillated to move the rods longitudinally. Springs 6 fitted between the arms I) and those arms of the levers b which form the handles, serve to so actuate the levers as to cause them to lower and retain the holders B upon articles arranged intermediate of the latter and the sup ports A.

Figs. 13 and 14 illustrate a modification of the means for operating the holders B. The holders are faced with some elastic substance, such, for instance, as the composition Z), ordinarily used for inking rollers of printingmachines, comprising glue and glycerine, having its lower surface protected by a sheet of india-rubber b. The holders are attached, as in the principal example of the improvement, to rods b sliding in sockets b To the sockets Z1 are secured plates (2 which have arc-shaped edges provided with ratchet-teeth. Levers Z7 are fulcrumed to pins b, which are connected with the plates 1), concentrically wit-h the curved edges of the latter. The levers D are provided with pivoted pawls b, which act in connection with the ratchet-teeth of the plate I). Springs I) hold the pawls in engagement with the ratchet-teeth. The rods 1) are provided with teeth and the adjacent end of the levers b are provided with a series of teeth extending concentrically with the pivot-pins b. The holders may be quickly lowered by swinging the levers upward and the pawls will hold the levers in position after such adjustment. By disengaging the pawls from the ratchet-teeth the levers may be swung in the reverse direction to elevate the holders.

Now I will describe a mechanism which is combined with each of the plates A to impart At a point above rotary motion to it for the purpose of presenting to the types 0' different portions of the surface of articles arranged upon said supports. In giving this description I will ask attention only to Figs. 7 and 8.

a designates an arm which at one end is provided with a hole of a size to fit snugly upon the flange 003, so that the arm may oscillate upon the same. At the outer extremity is a handle, by which it may be oscillated. To this handle an arc-shaped strip of metal a is fastened by means of a screw or otherwise. At one end this strip of metal is provided with a hook a, which is adapted to engage with a pin e fastened in the arm a a is a stop-arm fastened to the arm or. IV hen the arm a is oscillatedin one direction, its handle will abut against the stop-arm a and in this way be prevented from further movement. lVhen it is moved in the reverse direction, the hook at" will engage with the pin a and terminate the movement of the arm. It will thus be seen that the arm a has but a limited movement. This arm is made resilient; hence it may be bent downward. From its upper surface projects a pin 04 This pin is free to engage with any one of a number of holes a, arranged in a circular row in the plate A.

is another circular row of holes. The pin a may be disengaged from the arm (L15 and inserted in a diiferent position to coact with a hole 60 when desired to locate printing differently upon the articles carried by a support A.

The support A is rotated in the direction indicated by the arrow in Fig. 7. Normally the pin (L of the arm a will be in engagement with one of the holes of the plate. Vt hen it is desirable to impart movement to the plate. the arm 60 will be oscillated until arrested by the stop-arm to. Then said arm 0. will be depressed and oscillated reversely as far as permitted by the hook at", whereupon it will be released and on rising will cause its pin a to engage with the next hole of the series in the plate A, with which it is arranged to coact. The plate will'offer such resistance to movement as will cause it to remain stationary while the arm (115 is being returned to its normal position.

I will now describe the means employed for revolving the supports A to present articles upon said supports successively to the different types 0'. An arm (0 is loosely mounted upon the standard A and is connected with this standard by means of circular bands (L a, surrounding the standard. Its outer extremity extends into proximity with the inner side of the frame A and is provided with a longitudinally-movable bolt ta which is impelled outwardly by a spring (0 coiled around it and acting at one end against one of the bearings of the bolt and at the other end against a cross-pin inserted in the bolt. The outer extremity of the bolt is beveled. In the frame A are a number of holes or recesses (W, with which the bolt (1 may suecessively engage. hen the arm a is oscillated in the direction indicated by the arrow marked adjacent to it in Fig. 4, the beveled end of the bolt will cause it to be retracted from that one of the holes (L28 with which it was previously engaged, and as soon as the arm carries the bolt opposite to the next hole a the bolt will be shot outwardly and engaged with this hole. If afterward the arm is oscillated in the reverse direction to that indicated by the said arrow, it will impart motion to the frame A in the direction indicated by the arrow which is marked adjacent to the exterior of the frame in Fig. 4.

The arm 60 is oscillated by a link or rod a pivotally connected at one end to said arm and at the other end to one arm of a lever a which is fulcrumed between the ends by a pin 0. to a bracket (L32, which is fast ened to the floor A or other support. The other arm of the lever a is pivotally con nected to one end of a link a which at the other end is pivotally connected to a crankwrist (L extending from a disk a, which is affixed to a shaft A This shaft is shown as supported in a bracket a fastened to the floor A It is intended to be in constant motion during the operation of the machine; but it will of course only impart an intermittent motion to the frame A, because it will only transmit motion thereto when the arm a is oscillating in one direction.

Preferably the frame A will be locked positively in position except at such times as it is required to move. I will now describe a mechanism by which it may be so locked.

c0 designates an arm, which at one end is rigidly fastened to the support A and at the other end extends into proximity with the inner. side of the frame A. Near its outer extremity it is provided with bearings, which receive a longitudinally-movable locking-pin a A spring (1 surrounds this pin between one of the bearings of the pin and a crosspin inserted through the pin. This spring tends to force the pin e outward into one of the holes (1. of the frame A. Theinner end of the pin (1 is pivotally connected by a pin a to a lever a, which at one end is fulcru med by a pin a to a transversely-projecting portion of the arm a, and at the otherend is pivotally connected by a pin a to one end of a link a. The otherend of the link (Wis pivotally connected by a pin a to one end of a link a, which at the other end is pivotally connected by a pin a" to the arm (1 The links a a are of such length that on the completion of the backward oscillation of the arm ((123 in the direction indicated by the arrow which is marked upon it in Fig. 4:, they will oscillate the lever G21 in such direction as to effect the withdrawal of the pin (1, from that one of the holes (L28 of the frame A with which it was engaged. These links a a do not, however, exert any influence upon the pin w until about the termination of the for- IIO ward movement of the arm a and hence they leave the spring 00 free to act upon said pin a I will now describe the type-supports, the

.carriers for the latter, and the appurtenances of these parts.-

D designates a circular frame supported by arms d, extending from a tubular hub d, which fits upon the boss a of the support A The hub is secured against rotation by any suitable means-as, for instance, set-screws (Z passing through a tapped hole in the hub and impinging against the said boss a To avoid any misapprehension, I will add that this frame does not have any motion whatever.

To the upper side of the frame D a number of radially-extending slideways d are fastened. In each of the slideways one of the carriers D is fitted. Each carrier may have dovetailed sides, and its slideway 01 may have dovetailed Walls for the purpose of precluding the carriers from tilting. The outer end of each carrierD has a block d formed upon or secured to it, and in the outer face of each of these blocks is a horizontally extending slideway, to which is fitted a block d The block (1 and the portion of the block (Z engaging therewith will preferably be made dovetailed. In the face of each block (1 is a vertical groove receiving a block d Such groove and the block d maybe dovetailed to secure their engagement. A setscrew d passing through a slot in the blockd and engaging with a tapped hole in the block 01 provides for adjusting the latter upward and downward. A set-screw d passing through a slot in the block d and engaging with a tapped hole in the block 01 affords provision for adjusting the latter laterally.

7, upon the holder.

Each type-carrier D is reciprocated inward and outward radially to the frame D by means of a rod (Z The rod is connected with the carrier by means of a screw d, which may engage with one of a number of holes arranged in a row extending lengthwise of the carriers.

Obviously the types may be adjusted farther outward and inward by changing the connection of the rods (Z with the carriers D. They may also be adjusted laterally and vertically by means of the blocks d d d and rotarily by varying the position of their sockets 0 upon the holders 0.

The rods 61 are pivotally connected to bellcrank levers (Z which are fulcrumed to upright arms (Z rigidly affixed to the frame D, and braced by a cross-piece (Z consisting of a circular or ring-shaped body and arms extending radially therefrom to the arms (2 The bell-crank levers are connected by links (1 to a verticallymovable head (1, which is shown as of circular form and arranged concentrically with the hub cl of the frame D. On the under side of this head are pairs of lugs, to which the upper ends of the links d are pivotally connected by crosspins. otally connected to trunnions extending from blocks d, which are free to slide toward and from the fulcra of the levers d? in slots with which said levers are provided. The slotted portions of the levers are fitted with screws d", which are incapable of longitudinal movement, but which engage with tapped holes in the blocks so that by rotating the screws by means of a wrench the connection between the links d and the levers 01 may be shifted nearer to or farther from the fulcra of thelevers. operateinprintingmaybevaried. Theheadd is moved up and down by elevatingand depressing a rod (Z passing up through the support A and through the head at. This rod has afiixed to it collars (Z 61 Preferably these will be adjustably connected to the rodas, for i11- stance, by set-screws. WVhen the rod is raised, the collar at will abut against the hub of the head d, and the continued upward movement of the rod will serve to raise the head. NVhen the head 01 is raised, the carriers D for the type-holders are moved outward to the articles to be printed. A number of levers 61 are pivotally connected at the upper ends to the hub of the head d, and at the lower end are provided with inwardlyextending hooks. Near the lower ends these levers have eyes at, which slide along rods 01 when the head (1 is raised and lowered. These rods c1 extend from the brace r1 through holes in the head d. The rods are farther apart at the lower extremity than at the upper ends. On the raising of the rod (Z sufficiently to bring its collar d above the hooks of the levers (Z the latter will swing inward, so that their hooked ends will proj cct beneath said collar, and after this the rod d will raise the head 01 On the descent of the rod d its collar d will pull down the head at until the eyes 61 of the levers c1 reach the lower portions of the rods d, whereupon said levers will be swung outward sufficiently to cause their hooked lower ends to become disengaged from the collar (W. The rod 01 may therefore have a longer movement than that which is necessary for imparting to the head (Z the neces sary movement. The rod (1 is at the lower end connected by a link (E with the crankwrist or. Hence the rod will be raised and lowered by said crank.

I will now describe the means whereby the inking of the types is effected. The inkingtables F are preferably of circular form and supported so as to rotate about their axes. Each has a hub f fitting in a socket formed in a piece f, fastened to a bracket f A ratchet-wheel f is formed on the back of the The lower ends of the links 51 are piv-' IIO.

table. With this engages a pawl f having a weighted outer end which will keep its toothed end in engagement with the ratchet wheel and pivoted between the ends to a lever This lever f is held against a cam f G by a spring f. In this way each inking-table receives its rotary movement. It will be seen that each of the inking-tables is supported at an incline. The inking-rollers E are journaled in a carriage e, which is pivotally con nected at the sides to rods e, which are free to slide longitudinally in bearings forming part of a swinging frame 6 This frame at one end is affixed to a shaft f which carries the cam f. Springs 6 coiled around the rods 6 between the outer bearings and crosspins with which the said rods are provided, draw such rods inward or, in other words, toward the shaft f. The carriage 6- runs along rails 6 which extend vertically upward from a circular frame D and at the upper extremities are inclined or rounded inward or, in other words toward the center line of the frame D said rails being terminated in a plane with the inking-table with which they co-operate.

The types Cwill while in their normal positions have their faces substantially in a plane with the edges of the rails e The inking-rollers will, when the shafts f are oscillated, work across the inking-tables and the types and so apply ink to the latter.

The circular frame D is formed integrally with the arms (1 of the frame D, and hence is supported from the same hub (Z.

The swinging frames 6 are oscillated by means of links 2 which at the lower ends are pivotally connected to the outer ends of said swinging frames and at the upper ends are pivotally connected to a circular frame E, which is affixed to the upper end of the rod (Z Hence when this rod is raised and lowered the inking-rollers will be made to ink the types.

It will be seen that by providing for a lost motion between the rod (Z and the head cl, I am enabled to produce all the necessary movements of the inking-rollers and all the necessary movement of the types from one and the same rod.

In Fig. 12 I have shown an inking-table F faced with a sheet of india-rubber f In this example of my improvement the rollers E are intended to be made of metal, preferably of brass, and they are combined with a rubber-faced roller E which rotates in contact with them to distribute the ink. This combination I have found advantageous, especially for operating in connection with a type having a rubber face.

The articles to be printed are placed upon the supports A and the holders B are lowered upon them. The supports and holders may be adjusted up or down, toward or from the types,and at any desired angle relatively to the types. After the supports and holders shall have been properly adjusted the shaft A will move the rod (1 up and down, thereby causing the inking-rollers to apply ink to the types and forcing the types after inking to the articles to be printed and subsequently retracting them.

The types may severally consistof a holder c of sheet metal, cylindric in form, containing a mass 0 of composition such as is used for printers inking rollers, composed, for example, of glue and glycerine, and a sheet (3 of flexible material-such, for instance, as rubber-cloth-cut to the desired form and attached to said mass.
