SPECIFICATION forming part of Letters Patent No. 256,891, dated April 25, 188?.

Application nnuznmn 20,1860. modal To all whom. it may concern:

Beit known that 1, WILLIAM H. GOLDING, of the city of Chelsea, county of Sult'olk, and State of Massachusetts, have invented new and useful Improvements in Printing-Presses;

and'I do hereby declare the following to he a 'full, clear, and exact description of the some,

reference being had to theaccompanyin g drawings, and to the letters of reference marked thereon.

This invention consists mainly, first, in the special construction of the. mechanism employed for communicating movement from the main shaft to the'platen, the connection of the parts being such that the platen is caused to receive from the uniform revolution of the main shaft a. reciprocating movement, which has an I interval of rest when the platen is in position to receive the sheet; second, in the special construction of the mechanism for adjusting the platen to the face of the bed and also for throwing ofl" the impression; third, in the special construction of the inking-frame; and fourth, in the combination of an ink-distribw ter located beneath the bed, with certain other parts, as will be fully described hereinafter.

It consists, further, in certain special details of construction, which, in connection with the foregoing, will be fully described hereinafter. In the drawings, Figure 1 represents a side elevation of my improved press; Fig. 2, a vertical sectional elevation of the same; Fig. 3, a detached view-of theink-frame enlarged Fig. 4, adetcched view of the main crank and its connections; Fig. 5, a rear elevation of the press complete Figs. 6, 7, and 8, detail-views of the mechanism for actuating the ink-disk; Figs. 9, 10, and 11, detail views of the mechanism for giving the lower inlt-distrlbuter its longitudinal movement; Figs. 12, 13, 14, 15, and 16, various views of the platen; Fig. 17, a transverse sectional elevation of the platen and base-plate Fig. 18, an enlarged view of the crank b and connecting-rod e Fig. 19, an enlarged view of the shaft E, with its arms 0 Fig. 20, an enlarged view of the shaft F; Fig. 21,11n end elevation of the platen; Fig. 22,a plan view of the bar h Fig. 23, an enlarged view ot'one of the hook-rods for holding the ink-rollers, and Fig. 2+2 an enlarged view of the crank mechanism for actuating the press.

To enable others skilled in the art to make and use my improved press, I will now proceed to describe fully its construction and opera tion. 1

For convenience and clearness the same will be described under several heads, as follows First, the mechanism employed for communicating movement from the main shaft to the platen; second, the mechanism for adjusting the platen to the face of the bed and also for throwing 0d the impression; third, the inkframe and the mechanism for giving movement; to the same; fourth, the mechanism for giving movement to the ink'disk; fifth, the ink-distributor under the bed, and the mech anism for giving the same a double movement.

I. The mechanism employed for communicating movement from the main shaft to the platen.-A A, Figs. 1, 2, and 5, represent vertical side plates or standards, which are supported below by any suitable base or foundation, and are united above by means of the vertical bedplate a, Figs. 2 and 5, as shown.

B, Figs. 1 and 5, represents the main shaft, suitably held by proper hearings in the side plates, which is provided near one end, upon the inner side of the standard, with the crank i), Fig. 5, ofthe usual well-known construction, and at one end, upon the outer side of the standard, with a. gear-wheel, b, Figs. 1 and 5, as shown.

(3, Figs. 1 and 5, represents an auxiliary shaft, suitably held by proper hearings in. the side plates, which is provided upon the inner side of the standards with a crank, c, Fig. 24, and upon the outerside of the standard with a pinion, 0', Fig. 1, engaging with the gearwheel b, as shown.

D, Figs. 2 and 24, represents a. treodle of any proper construction, and d a connectingrod having a slot, at d, at one end and a spring-clamp or other proper means of connection at the other. By means of the connecting-rod the treadle is united to the auxiliary shaft for the purpose of giving movement thereto.

E, Figs. 2, 4, 5, and 19, represents a. shaft suitably held by proper hearings in the side plates, which is provided with the arms a 0, ex-

tending therefrom, as shown, these arms themselves being provided with the ends a, Fig.

10, having openings, asshown {and c, Fig. 4, represents a right-angled extension; having ends 0, with openings, as shown.

e representsa connecting-rod of any proper shaft suitably held by properbearingsin the,

free ends of the barsff, Fig. 1, whichbcrs are themselves held at their fixedends bythe shaftf', extending across themachine at the rear upper corner of thesame, as shown.

f f g nd 5, represent connectiugrods, by means of which theshnft F is unitedto the ends of the arms a.

f Figs. 2 and 20, represents ahollow shalt inclosing the solid shaftF, which is provided,

first, with propereopenin'gs for the projection of theends of the connecting rodsj throughit to the shaft F, and,'second,witharmsff, Fig. 2, having openings in the endyas shown.-

G, Fig.12, represents the' haseplate of the platen having the supportinghrmsg g, by meansofwvhich and proper securing devices it is hinged or pivoted to the-side 1 plates, .as shown.

g gWepresent ears, and g 9 belts or pins, by means of which the arms ff are pivotedto the platen.

9 represents a fastening-screw, by means of which the pin g is held against accident-.11 displacement.

The-operation 'of these partsis substantially as follows: Movement having been communicalled to the main shaftin any proper manner, the platen receives therefrom through the intermediate mechanism described, an oscillating movement. At the end of the return movement of the platen, after making an impressiou, it has an interval of rest. This results mainly from the construction of the connesting-rod 'e, Fig. 8, audits arrangement relntively to the crank of the main shaft. The connecting-rod c, it will be observed, is made nearly of the same length as the crank of the main shaft, and is so united thereto that when the crank is in its lowest position, as shown in Figs. 5 and 18, the center of movement of the upper end of the counecting'rod is nearly coincident with the center of movement of the main shaft. -From this construction and arrangement it follows, when the parts are in this position, that the continued movement of the crank will 'give to the connecting-rod simplya. swinging movementupon the pin or belt which unites it to the extension 0, as indi cated' in Fig. 4, without liftingthe extension of the shaft E in a vertical direction. The exact coincidence of the crank andthe connect ing-rod in their movement continues onlywhile the two lie in the some vertical plane; but as in approaching end leaving this line-the vertical movement of the rod lsnecessarily small, it follows that a suflicient interval of. rest is obtained'for thepurpose desired. The vertical movement of the connecting-rod, resulting from the revolution of the main shaft, is communicated to theextension of the shaft E, Fig. 2, and the latter being swung upon the bearings, the connecting-rods f f arecaused to lift the shaft F, supported by the swinging armsff, as shown. By the elevation of the shaft F the armsf of the hollow shattf are caused to swing back the hinged platen G against the bed. The arms of the shaft E and connecting-rods act together in the manher of a toggle-joint. By the action of this toggle movement the shaft'F, held by the swinging arms f f, is caused to describe the arc of a circle and to force backward in its upward movement thehinged platen by means of the armsf.

II. The mechanism for adjusting the platen to the face of the bed'and also for throwing of the inqiresstomfiG, Fig.=12, represents the =baseplate of the platen,- before referred to; g g, Figtlfiywalls located on the sides of the inner .facc of thehase-pla'te, and g g" walls located near the top andlbottom edge of the same. i lg, Fig. 16, r presents ledges on the outside of the walls 9 which are provided with the end portions, g, inclined as shown, and the :projection g, as shown.

9 g represent wedge-blocks having above ahorizontal beaning face, and below an inclined hearing-faceadapted to restupon the end portion, as shown.

, represents .an adjnstingscrew located at the properpointin the side wall, by means of which the wedge-block may be advanced upon its inclined seat when it is desired to elevate its horizontal benring face.

g represents a. spring interposed between the inner end of the wedge-block and the pro jections g or the projection g", hereinafter referred to.

g" repiesents a. bar adapted in form and size to rest upon the horizontal bearing-faces of the wedge-blocks, as shown, which, is provided upon the hpper side, at each end, with an inclined bearing-face and upon its lower side with a projection, g, as shown. 9 also represents a bar precisely like the bar excepting that it is without the projection g, which bar, when in position, lies with its inclined bearing-faces in contact with the corresponding faces of the bar 9", as shown.

9 represents a shaft held by proper bearings upon one of the side walls of the baseplate, which is provided with crank-arms g, Figs. 13 and 16, having links 9", Fig. 16, secured to the-outer ends of the bars g, as Shown.

9'" represents a crauk'handle, by means of which the shaft 9 is partially revolved, when desired, for the purposeof giving longitudinal movement to the bars g", as will-be hereinafter described.

9 Fig. 16, represents a. spring-latch, by

means of which the shaft g and the attached with the threaded socket-piece g, the wallsand g, and the bearing-ribs g, the outer ones of which latter are provided with the flange g, as shown in Fig. 21.

g, Fig. 11, represeutsa screw which extends through the basc'plateinto the socketpicce of'the face-plate, as shown.

9 represents an intermediate spring hear-- ing at one eudugcinst the head of the screw and at the other upon the bracketrplatc, as shown. When the faceplate is in place the faces 9 9 of the plate 9 bear against the walls 9" g by, means of which construction the lateral and longitudinal position of the face-plate relatively to the base-plate is accurately'determined.

9", Fig. 15, represents a faceplate by means of which the wedge-blocks andparts are properly covered;

, 9 represents a screw by means of which the bar 9" may be moved independently-0t the other parts, in order that the platen may be adjusted at the top and bottom, when desired, for the purpose of regulating the impression. The operation of these parts is readily understood. The manner of adjusting theplaten is as follows: The face-plate of the platen is adj ustrd' to the face of the bed by simply turning any one of or all of the screws y" in the proper direction, in conscqueuceot which each wedge-block 9" is eithermovcd up the inclined portions g" by the direct action of the screw, when the same is moved in a forward directio u',,or' is moved dowuthe inclined portions by the reaction of the spring 9 when the same is moved in a rearward direction. 'After the platenis adju'stedso that it is perfectly true with the face of the bad it is seldom necessary to change the position of the wedge-blocksg.

The. twohand-screws g, controlling the moremeut of the double wed ge-block g, are used to regulate the amount of impression upon the type. By these connected wedges the top and bottom lines of the platen are kept perfectly parallel with the bed, andthe impression can therefore be changed quickly for small or large forms and the varying thicknesses of paper and card-board. From this action it follows that the face-plate ol the platen is moved either to or from the base-plate, according to the circumstances of the case, the first movement or movement toward the base-plate being permittedby the yielding of the spring g",

aud the second movement or movement from the base-platebeing caused by the reaction of the same spring whenever the same is free to act.

The manner of throwing oh the impression is substantially as follows: The parts being in their normal position, so that the platen occupies the position shown in dotted lines, Fig. 17, the impiession is thrown oil by forcing down the crank-handleg Fig. 12, the springlatch g Fig. 16, having been first disengaged, by which means the shaft 9" is partially revolved, and the bars 9, attached thereto, are drawn along upon the bars 9 The inclined portions of the bars being thus moved down the inclined portions of the bars 9, the faceplate of the platen is drawn near to the baseplate by the reaction of spring g Fig.17; The face-plate of the platen having thus been setback, it follows that the se me will notcome llJ'QOlllflCli with the type upon the bed when swung backward by the mechanism previously described, and hence no impression will be upon the bed for the purpose'ot' receiving an impression therefrom.

Ill. The ink-flame and the mechanism for gin zug movement to the same. H, Fig. 3, represents the ink-frame having a bearing-opening, h, through which the fixed bearing hubs or journals h project from the side plates, as shown. 7L2 represents an arm projecting frourthe frame, and h, Fig. 1, a connecting-rod, by

' means of which this arm is united to a. crankpiu, it, upon the main gear-wheel.

k Figs. 3 and 5, represents an intermediate couz'iecti'ug-bar, by means of which the rear ends of the ink-frame are united together.

h" i Fig. 3, represent side bars rising from the base portion of the frame, which are united above by the cross-bar h, as shown.

h h represent hollow studs rising from the base portion, the openings into which are in line below certain openings, h, Fig. 22, in the crossbar h as shown.

h h? represent the hook-rods for holding the rollers in place, the upper ends of which extend through the openings h in the crossbar. h, and the lower ends of which extend into the opening of the studs h" h", as shown.

7H represents a collar or shoulder upon the lower end of each rod h and h" a. spring inclosiug the rod, the lower end of which bears upon the collar Id, as shown. These collars orshoulders have guide-projections, as shown in Fig. 23, which gnovc in proper pockets or recesses, by means of which construction the rods are absolutely held from turning out of place.

It represents a. bar having openings at its ends, through which extend the hook-rods, as shown, which bar is provided with a central eye, hf, or other proper means for securing the upper end of the spring It, the lower end of which is secured to the base portion of the frame, as shown.

It" represents a similar bar, which is pro vided, in addition, with an extension, 1:",proiecting over the bar It", as shown.

If desired, the upper end of the hook-rod maybe provided with a non-removable screw, it", as shown in Fig. 23, for holding the end of the ink-roller and preventing absolutely its accidental escape.

The operation of these parts is substantially as follows: The ink-frame, asawhoie, receives an oscillating movement from the revolution of the main gear-wheel through the intermediate mechanism described. The rollers, by means of the hook-rods and springs, are held with an elastic pressure. By means of the bars h" and h the power of the uuxiliar' spring It is added to that of the main spring h", and consequently a more uniform tension is obtained.

IV. The mechanism for giriug movement to the ink-disk-I, Fig. 2, represents a bracket or standard extending upward and rearward from the upper edge of the base-plate, which is pro vided, first, with a sleeve, 5, adapted to receive and hold thecentral stud or pin of the ink-disk; second, with the extension 1'', Fig. 8, having cars i with openings through them and, third, with an extension 1, with an opening through the same.

i, Fig. 6, represents an arm provided atone end with ears i a, having openings through them, and a cam-projection, i, as shown, and i at the other end with ears 1, supporting the weighted pawl i, as shown. A pin extends through the openings in the care i i for the purpose of uniting the arm i to the bracket 1, Figs. 2 and 8, as shown.

i, Figs. 7 and 8, represents an arm having at one end a proper opening adapted to receive a bolt or pin,b v means of which it is united to the car 5, Fig.8, of the standard I, an arm, i

and a cam-projection, i, as shown.

i", Fig. 5, represents an ink-disk having on its lower face a central stud or pin fitting into the sleeve 2', Fig. 2, of bracket 1, and ratchetteeth located near the periphery of the same, Figs. 2 and 5, as shown.

i represents an arm upon 0! the ink-frame.

The operation of these parts is substantially as follows: The ink-frame having received its oscillating motion in the manner previously described, the arm 1' of its crossbar is caused, in its upward movement, to come in contact with the arm i and rock or oscillate the same upon its bolt. llymcaus of this movementits cum-protection i" is caused to come in contact, with the. cam-projection i of the arm i and give the latter a partial revolution upon its axle-pin. By this movement the pawl i" is caused to engage with the rutchct-tccthoi' tho the cross-bar h disk and give itaparlinlrevolution. The arm i, being held at an angle, is returned to its normal position by the action of gravitation, when the arm i is permitted to return by the backward movement of the arm i" upon the bar It. From this it will be understood that the ink-disk receives a partial revolution at each oscillation of the ink-frame.

Y. The ink-distributor under timberland the mechanism for giving the name a double moremeut.--J, Fig. 2, represents a rod or shaft extending across the machine, which is supported by the side plates, as shown.

j represents the ink-distribut r consisting ot'a curved platehaving arms which areloosely secured upon the shaft J by sleeves or other proper means in such manner as to permit the plate to oscillate upon the shaft and also to move in a lateral direction thereon.

j, Figs. 9 and 10, represents a cam upon the main shaft, the groove of which is adapted to give a lever-pin resting therein a forward and l backward movement, with an interval of rest after each change.

j represents a lever pivoted in any proper bearings upon one of the side plates, the pin of which rests in the groove of the cam, as shown.

j represents a bent portion of the short arm of the lever, and j a spring-bolt latch snitably held therein.

j represents a slot cut in the edgeoi' the distributiou-plate, into which extends the upper end of the spring-bolt when the parts are in their normal position.

The operation of these parts is substantially as follows: The ink-rollers, in completing their downward movement, pass over the ink-distribnter, the latter being held stationary d urin g this movement by its contact with the bolt j. The ink-rollers, in starting to return, lift the distributor by the friction of contact, and consequently move with the same without, revolution for a short distance. By means oi this action the rollers are caused to begin their revolution in return at a difl'ereut point relatively to the type than that at which they stopped, and hence a new roller-surface is presented to the type in the return movement. The distributer also, in addition to the vibratory movement given to it by the rollers, receives a lateral movement upon the'shat't at regular intervals for the purpose at presenting a fresh surface to the rollers at each downward movement of the same. This lateral movement is caused by the action of the cam and the intermediate lever mechanism dcscribcd, the cam being turned to move the distributer tlrst in one direction and then in the other before the passage of the rollers over it.

ly depressing the bolt the distributor may be swung backward out of the way when it is dosircd to dispense with the use of the some, it being held in this rearward position by contact with the bolt when the same is returned to its normal posit ion.

Some of the advantages of the foregoing constractiou are as follows: By means of the construction and arrangement of the crank-shaft and connecting-rod the platen is given an oscillating movement with an interval of rest, by means of which ample time is afl'orded for feeding the sheet. By means of the mechanism for regulating the impression it perfect adjustment of the platen may be readily and quickly made. By means of the mechanism for throwing off the impression the operation may be instantly performed, whenever desired. By means of this construction, also, the platen is supported by perfectly solid bearings having no appreciable wear. By means of the lower ink-distributer n more thorough distribution is obtained and a more even application of the ink to the form. By means of the mechanism for holding the inking-rollers an easy movement and nearly-uniform tension are obtained.

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

1. In combination with the platen, the main shaft, and the crank, aconnecting-rod with intermediate connecting devices, substantially as described, for uniting the connecting-rod to the platen,suhstantiallyas described, the pivot of the upper end of the connecting-rod being during a portion of its movement nearly coincident with the center of the main shaft, substautially as and for the purpose set forth.

2. In combination with the bar g" and the blocks 9 for adjusting the same, the movable 35 bar 9, as set forth.

3. In combination with the baseplate and face-plate of the platen, the led ges g" g, wedgebloehs y", springs g", and bars g g".

4. In combination with the hook-rods h 4 ceives a vibration by the upward movement of 50 the latter, as described.

7. In combination with a pivoted ink-distributer located below the bed, mechanism, substantially as described, for giving it n lateral vibration, and inking-rollers, substantially 5 5 as described, for giving a. swinging movement. This specification signed and wit iessed this 28th day of February, 1880.
