SPECIFICATION forming part oi Letters Patent No. 529,489, dated November 20, 1894.

Application filed January 3,1894. Serial 110.495.561- (No model.)

To aZZ whom it may concern:

Be it known that I, WILLIAM H. GOLDING, of Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and usefulImprovementsinPrinting-Presses, of which the-following is a specification.

This invention relates to certain improvements in printing presses of the class employing an oscillatory platen in conjunction with a type-supporting bed and an intermittentlymoving distributing-disk, and consists in the novel constructions and arrangements of parts hereinafter described and claimed.

Reference is to be had to the annexed drawings and to the letters marked thereon, forming a part of this specification, the same letters designating the same parts or features, as the case may be, wherever they occur.

The stationary supporting frame a of the machine is formed with a centrally-located and vertically-extending web a, and a crankshaft a? is supported in a bearing on one side of the frame and bearing on said web, the crank a of said shaft being connected with the platen-operating motion. A large gear a is mounted on the shaft a beside the crank a and is rigidlyconnected with the latter by bolts a entered through the web of the gearand tapped into the crank. By thus conmeeting the gear and crank near the periphery of the gear, torsional strain between the gearand crank-shaft is obviated; and, by connecting the gear directly with the crank in this manner, the gear is brought as nearly as possible to a direct connection with the platenmotion, and a true action of said motion insured. The driving-shaft b is supported in a bearing on the web a, and a bearing on the side of the frame opposite that where the crank is located, and said driving-shaft carries a spur-gear b in mesh with the large gear a, and a fly-wheel 1) outside the frame, and also a fast and a loose pulley b b. A rock-shaft c is supported in stationary bearings, and a shipper c is affixed to it at one end, and projects therefrom for engagement with the belt which embraces the pulleys. A treadle c is also affixed to the said rock-shaft, and projects laterally and upwardly therefrom, so that by depressing the said treadle the belt is thrown over onto the fast-pulley and the machine thereby set in operation. The rock-shaft has another lateral arm 0 aflixed to it, and a lever o is arranged to coact with said arm a to shift the belt onto the loose pulley and stop the machine. The lever c has a shoe c -for contact with the periphery of the fly-wheel 6 so that said lever serves the double purpose of shipping the belt and putting a brake on the fly-wheel. This brakelever is designed to be operated as a treadle by the attendants foot. By this arrangement, the attendant may control the operation of the machine conveniently with one foot.

The platen d is pivoted to the frame a at d, and is oscillated by means comprising a link 01 connecting the crank a with radiusbars d pivoted to the frame a, a toggle composed of members 61 and d connecting said radius-bars with the platen, and radius-bars d connecting the toggle with the frame a and extending across the ends of the platen.

My invention contemplates an improved throw-off device, by which the platen may be quickly changed from operative to inoperative adjustment and vice versa, with relation to the bed; or, in other Words, pressure of the platen against the type applied and removed, the construction being as follows:

The member (1 of the toggle is connected with the platen by a shaft e, which, where it engages the toggle-member, is eccentric, as indicated at e, whereby, upon turning the shaft, the relation of the platen to the togg1e-member d is changed. An arm e is affixed to the shaft 6, and a handle 6 is jointed to said arm, and is normally held in alignment therewith by the engagement of a double-tapered and spring-pressed latch e on the handle with aV-shaped notch in the arm. The handle has a lateral extension, which is formed on the inner side with a substantially diamond-shaped lug e adapted for engagement with a curved flange or rib 6 formed on the end of the platen. When the platen is in operative adjustment, so that pressure isthadagainst the type (see Fig. 3), the large side of the eccentric e is rearward, and the luge abuts the front end of the flange 6 When it is desired to throw off the pressure, a rearward pull is exerted on the handle a which first causes the latter to turn on its pivot, and throws the lug e up past the end of the flange e, the latch e permitting this movement of the handle by riding up on one side of the notch. Then the continued pull on the handle carries the arm 6 back on its pivot, the lug e riding on the upper side of the flange e, and the platen is shifted to its inoperative position,shown in Fig. 4, thelug e dropping behind the rear end of the flange e by reason of the action of the tapered spring-pressed latch against the side of the V-shaped notch. To restore the parts to their first adjustment, the handle is pushed from the. operator, and first turns on its own pivot carrying its lug e downward past the end of the flange a and then the arm 6 is moved forward on its pivot, the lug e riding on the under side of the flange, andwhen it reaches therear end of the same springing behind this end by reason of the co-action of the latch and V-notch. This construction provides very convenient and easily-operated means for throwing the pressure off and on and locking the platen in each adjustment, the operator having simply to move the handleback'and forth without having to operate any other devices.

The-movement of the handle on its own pivotis. limited by its lateral extensions e abutting portions of the arm 6 and the movements. of the latter are limited by its projections e 'abutting the ends of the flange e.

I employ novel counting-devices (see Figs. 7 and 8), comprising a registering-mechanismf, of suitable construction, attached to the upper side of one of the radius-bars d, and having a projecting actuating-arm f extending in the direction of length of the bar d and having a laterally-projecting finger f An arm f pivoted to a bearingf affixed on one endof the platen, has a lateral finger f xtending transversely of the finger f and adapted to stand in the path of the same. (See Fig. 7.) In the operation of the press, the bar d has a movement crosswise of the end of the platen; and when the latter is in operative position, or in other words when the pressure is on,each time the bar rises, the fingerf on the armf of the registering-mechanism encounters the flngerf of the arm f on the platen, and is caused thereby to actuate the registeringmechanism. When, however, the platen is moved back to itsinoperative position, or when the pressure is OK, the flngerf of the arm f is carried back out ofthe path of the fingerf of the armf (see Fig. 8), and hence the registering-mechanism will not beoperated. By this arrangement, the counting-devices operate only while printing is in progress, and reciprocations of the platen when the pressu reis off do not affect the counting-devices.

When the arm of theregistering-mechanism acts against the arm f, the latter is rigidly held by abutment of a stud f carried by it against the bearing f The arm may be moved out of operative position altogether, when it is not desired to use the counting devices, by turning said arm over on itspivot, as indicated in broken lines in Fig. 9. A spring f holds the arm in its two positions, said spring passing the center when the arm is moved from one position to another.

A. numberof advantages resultfrom mounting the register on the draw-bar rather than on a bracket fastened to the side of the press as has heretofore been done, viz: greater sim plicity by not requiring an extra part for support; reduction in cost for the same reason; and greater convenience and less liability to derangement by reason of the fact that it is carried down with the drawbar and out of the way when the attendant is feeding or making ready, and it does not project laterally so as to be in danger of receiving a blow.

A rock-shaft g, supported in hearings on the platen above the pivot of the latter, has affixed to it gripping-fingers g, extending over the face of the platen to act upon the work thereon. A spring 9 tends to turn the rock-shaft in a direction to move the grippers away from the platen, and pressure of said grippers against the platen is effected by the engagement of a curved arm afflxed to the rock-shaft with a stop-arm g on the frame a. When the platen is pressing against the type, the upwardly-curved front end 9 of the arm is behind an anti-friction roll on the end of the arm g and by its engagement therewith causes the grippers to press againstthework. Upon the retraction of the platen, the engagement of the said roll with the curved end of the arm 9 causes the pressure of the grippers to be maintained momentarily. Then the recedingportion or incline g of the curved arm receives the said roll, and the spring g holds the grippers back, so that, as theplaten moves forward away from the bed, its face'is' ICC separated from the grippers. Upon the return of the platen, the grippers are pressed against its face by the front curve g of the arm encountering the anti-friction roll. The pressure may be regulated by adjusting the arm g which is mounted on a bolt 9 and carries a set-screw 9 bearing against a lug on the frame.

One objectof my invention is to provide improved means for imparting a progressive step-by-step movement to the distributingdisk, and for converting the same into a stepby-step vibratory motion of the disk, to SH- cure a blending of dilferent colors, when desired. The means employed to accomplish the above objects are as follows:

The distributing-disk h is rotatively supported on the frame, and formed with an annular flange h on the under side; and an arm 71?, pivoted to a support on the frame, extends under said flange, and is formed with a wedgeshaped lug 7L projecting over the inner side of the flange, and having a channel 72. containingaballh which bears against the flange. It will be seen that, under one direction of movement of the arm, thisballwillbe caused to bind against the flange, and the disk will be carried around with the arm; whereas, under the reverse direction of movement, the ball will roll freely on the flange, and no movement of the disk will ensue. This is due to taper of the ball-channel with respect to the flange. The arm h is intermittently vibrated through the following connections with the rocker t which carries the distributing-rolls t": A striker t affixed to said rocker, encounters a toothed segment 2, pivoted to the frame and limited in its movements by a pin on the frame, engaging a slot in the segment, and said segment meshes with teeth 2' on the under side of an arm "6 pivoted on the same support as the arm 71 and rigidly but detachably connected with the latter bya screw i passing through the arm 2' and through a lateral extension of the arm 7L2. The parts are restored to theirinitial position by gravity after having been actuated by the striker.

This ball-and-wedge device for effecting the progressive step-by-step movement of the disk has the advantage of noiseless action, and moreover of causing irregularity in the length of the step, which insures a more even distribution of ink over the surface of the disk.

When different colors are to be blended on the disk, it is desirable to impart to the latter a step-by-step vibratory motion, and this is effected by the following arrangement: The arm h is clamped to the flange h, by means of a set screw 2 entered through a lug 2' and engaging a notch t in the flange, and the said arm h -is disconnected from the arm 2' by withdrawing the screw 2' and step-by-step vibration of the arm h and consequently of the disk is effected through the following means: A ratchet-wheel j is rotatively supported on the frame a, and carries a crank-pin j, and the arm 72 is formed with a slot 3' at its outer end, adapted to be engaged by the said crankpin. When blending of colors is to be done, the arm h is swung around over the ratchet, and the crank-pin is engaged with the slot in said arm. (See Figs. 14 and 15.) An arm k, pivoted concentrically with the ratchet-wheel, carriesa pivotal pawl for engagement therewith, and said arm is connected by a rod 70 with the arm When the blending is not in progress, the pawl 70' is thrown back on its pivot, as shown in Fig. 11, so as to be inoperative, and the vibration of the arm 2' does not affect the ratchet-wheel. Tith the parts adjusted for blending, however, the pawl is thrown into engagement with the ratchetwheel (see Fig. 15), and the vibrations of the arm t then cause the ratchet-wheel to be turned step-by-step, and the arm 71 consequently to be moved step-by-step first in one direction and then in the opposite direction, by reason of the engagement of the crank-pin on said ratchet-wheel with the said arm, and thus the desired step-by-step vibration of the disk is obtained. The crank-pin engages a radial slide-wayj on the ratchet, and is controlled by a screw f, so that by turning the latter the throw of the pin can be regulated. In order to engage the pin with the slot in the arm, it is moved back to the end of the slideway, and then moved into the slot when the latter is brought in line with it by swinging the arm around on its pivot.

In order to prevent the ink from congealing on the disk or on the auxiliary distributing-surface 11 below the bed, these parts are subjected to heat through the following agencies: A gaspipe 0 enters the rear of the machine, and has two branches 0 0 one leading to a point below the disk, and the other to a point below the auxiliary distributingsurface, and each having burners o Bafflep'lates 0 are fastened above said burners, and cause a proper distribution of the heat, and valves 0 in the branches 0 0 regulate the flow of gas to the burners.

Another improvement contemplated by my invention relates to adjustment of the typesupporting bed, and is illustrated in Fig. 6. The letter 19 designates the stationary support for the bed, the rear wall of said support being formed with socketsp', which are engaged by rounded ends of universally-adj ustable blocks p V edges 19 are interposed between the said blocks and feet 19 on the bed 10 the straight sides of the wedges engaging the bed and the inclined sides engaging the blocks. The wedges are adjustably connected to-. gether by means of a screw 19, loosely engaging one of the Wedges at one end, and screwed into a threaded clamp 19 on the other, the latter being drilled out to admit an implement for turning the screwandadjustingthewedges with relation to each other. Such an implement may be inserted through an openingp in one end of the support. The two Wedges are adjusted together by means of a screw q, loosely engaging one of them and passing through a threaded clamp g on the bed, said screw'being in linewith an opening g in the support, so as to be accessible for adjustment. A set of these ad justin g-devices are located at the upper and at the lowet end of the bed. By adjusting the wedges of each pair with respect to each other, lateral adjustment of the bed is established. By adjusting the wedges togetherin pairs, vertical adjustment of the bed is established. By means of these adj ustingdevices, the bed can be made absolutely true with respect to the platen. The screws are engaged with the right hand wedge 19 by means of T-shaped slots 8 in said wedge, see Fig. 16, which are occupied bysuitably form ed heads on the screws. The nuts p and q are split and clamped around their respective screws by means of bolts, as shown att in Fig. 17.
