Serial No. 430,470.

This invention relates to a proof press, p articularly useful in connection with printing proofs without the necessityv of enteringV and pn locking the forms in a printing press and 5 with which the type, illustration plates and the like are held in a chase located at the upper side .of a movable truck or turtle as it is called, which may be moved into .the ma-A chine and automatically properly located machine and then secured against movement, after which the type may be inked, paper drawn over the inked type and the paper pressed against the type by n means of a suitable movable platen roller so as to print a proof sheet which may then be examined for mistakes or the like, the turtle which carries the chase and the make up type and illustrative plates therein being Y m quickly and easily removed from the machine by merely rolling the same over the floor away therefrom.

This invention is concerned with many novel constructions and combinations and ar- 1 rangements of parts for effectively attaining the main purpose of the invention as stated.

n '3K0 against the inked type is of a floating character so as to conform to the chase and the type upper surfaces, within certain limits,

it is not necessary at all to pay any attention to irregularities in the floor or minordiiferences inthe height and level of the different trucks or turtles which may be introduced into the machine, or to watch out for different leveling conditions which may come from a wear of the bearings orvouter surfaces of the casters on'which the turtle is mounted as the floating character of the frame which carries the inking mechanism and the platen roller permits the same to conform to the surface of the type which is to be inked and f against which the paper is to be pressed by the roller. v

There are many other features of construction and novelty in the mechanism for the effective inking of the type and movement of the platen roller over the paper above the type; for the elimination of ink at the upper edges of the ends and sides of thechase; for transferring ink to the type inking rollers simultaneously with the movement ofthe platen roller over the paper to press it against the type previously inked or, if desired, for applying and transferring ink to said type inking rollers separately and distinct from any movement ofthe platen roll'- er, all of which will be apparent upon understanding the invention from the following description taken in connection with the accompanying drawings, in which,

Fig. l is a longitudinal vertical section through the machine of my invention showing the turtle carrying a chase disposed be-V tween the sides of the machine.

Fig. 2 is a plan view of the machine.

Fig. 6 is a fragmentary plan view of the construction illustrated in Fig. 5, and

Fig. 7 is a fragmentary horizontal section Villustrating a 'detail of the mechanism for either simultaneously or individually rotating the main inking roller from which ink is transferred to Vthe type inking rollers.

Like' reference' characters refer to like parts in the different figures of the drawings.

In the construction of the machine a lower supporting` frame is provided which in construction includes two substantially independent and `spaced apart elongated vertical frames l between which the turtle or truck 95 which carries the chase with type therein is adapted to be placed. These side frames 1 are of a substantial character and are designed to be firmly located and secured on a floor; and thereY are substantially no cross 100 connections between said side frames except in so far as the frames are used to support the ends of a rock shaft, hereafter described.

Over the two spaced apart frames 1 a floating frame structure is mounted upon which substantially all of the mechanism for inking the type and operating the pressure platen roller is secured. This floating frame includes two elongated sides 2 located one directly over the upper end of each of the frames 1. The sides 2 of the floating frame are connected together at front and rear by cross rods 3. Various other rods and shafts, on which the mechanism carried by the floating frame is mounted, also extend between the sides 2 and at what may be termed the Jfront end of the machine are vupwardly extending brackets 4, one attached to each of the sides 2 of the floating frame, over which an angular sheet metal cover 5 is disposed and secured which in practice is to serve as a support for a sheet of proof after it has been printed in the machine.

The sides 2 of the floating frame have a floating connection with the lower side frames 1 through pins G connected to and extending upwardly from the frames 1 into suitable sockets at the lower sides of the sides 2 of the floating` frame, coiled compression springs 7 being disposed between the frame members 1 and 2 which in a measure support and balance the weight of said sides 2 of the floating frame. There are two of these pins with compression springs around them at each side of the machine which are symetrically located with respect to a central transverse plane substantially midway between the ends of the machine.

A means is provided Jfor raising and lowering the floating frame with respect to the stationary side frames 1 below. To this end a pairrof toggle links 8 are pivotally connected at their upper ends at 9, one at each side of each of the lower stationary frames 1 and at their lower ends have pivotal connection at 10 to'another p air of toggle links 11 which extend downwardly and have a pin or rod 12 passing through their lower ends, at the same'time passing through a vertical slot 13 ,in a horizontal frame member ot the lower stationary side frame 1. Two bars 14 are pivotally connected at 15 at their upper ends adjacent the lower side of each floating side frame member 2 and extend downwardly alongside the toggle links. The pin or rod 12 at its ends passes through the bars 111 which are continued below said pin or rod 12 between two guides 16 projecting laterally from the same horizontal frame member of the side frame 1 in which the slots 13 are cut. The toggle link constructions and the bars 1.4 are located in a transverse vertical plane substantially midway between the planes of the 'pins 6 previously described.

A horizontal rock shaft 17 (see Fig. 1) extends between and is mounted at its ends on the side frames 1 to which, adjacent one ot said side frames, a bell crank lever 18 is permanently secured having an upwardly extending arm 18a. An equivalent arm 18a is connected to the rock shaft 17 adjacent the other side frame 1. Rods 19 extend from the upper ends of the arms 18a to the pins 10 at the knuckles of the toggle levers described and in practice a turnbuckle adjusting nut 2O is disposed in each rod 19 so as to adjust the length of said rods as may be desired.

The forwardly extending arm of the bell crank lever 18 has a vertical link 21 pivotally connected at its upper end thereto which at its lower end is pivotally connected to a foot lever 22 located at the inner side of one of the lower side frame members 1 and pivotally mounted at 23 thereon at a point between the ends of said foot lever. The foot lever at its ends has outwardly extending foot engaging pedals 24 and 25 which extend through openings in the frame 1 for ready operation by the foot of the operator of the machine.

The turtle or truck which carries the chase within the sides of which the set-up type is disposed is adapted to be rolled between the spaced apart sidesot both the un der supportmg frame and the floating frame and under the rear cross rod 3. This truck includes a substantially horizontal top 26 supported at its corners by deper ding vertical posts or legs 27 which are connected by cross tubular bars 28 and longitudinal tubular bars 29. Casters or rollers are mounted at the lower ends of the legs 'for readily moving the turtle over the floor and into proper position with reference to the machine. On the upper side of the table 26 the chase 30 is placed within which is the set-up ot type plates for illustrations and the like as indicated in out-line at 3l, the space shown between the inner sides of the chase and the outline of the type being for the usual printers 'machinery for securing and holdingthe type in the chase. L

On the floor near the rear ot the machine and between the sides thereof, a supporting bracket 82 is secured through the upper end of which a short shaft is mounted having a cam Enger 33 connected to its front end and a foot pedal lever 34 to its rear end as shown. lVhen the turtle has been moved to position between the sides 1 of the lower frame bv operating the foot pedal in one direction the cam finger is brought against vthe rear cross bar 28 ot the turtle frame thereby securing it in position against rearward movement; The release of the turtle is accomplished bv operating the foot lever in the opposite direction so as to bring the cam finger below the cross rod 28 which it operatively engages.

When the turtle is rolled into 'the machine vbetween the sides thereof one of 'the front corners comes against an 'incline 35 (see Fig.

2) which has the eectof moving the turtle toward the other side of the machine and brings the corners of the chase located at the upper side of the turtle at its front ends under overhanging brackets 36 through which adjusting screws 37 pass, while the rear corners come under somewhat similar overhanging brackets 38 having like adjusting screws 37 passing therethrough. The

side of the top of the turtle opposite that at which the incline engages is thereupon brought against a side gauge bar 39 (see Fig. 2) which is carried by the adjacent side 2 of the floating frame.

A member 40 is pivotally connected at 41 to one of the brackets 38, as shown in Fig. 2, and carries two rollers 42 and 43 adapted to engage against a side and at the outer end of the chase 30. The member 4() has a curved slot 44 therein. A hand operated lever 45 passes over a supporting bracket 46 attached to and extending forward from the rear rod 3 and is pivotally mounted between its ends at 47 on the bracket, and atits front end has pin 48 entering the slot 44, By turning the hand lever to the position shown in Fig. 2 the rollers 40 and 43 engage the outer end and an adjacent side of the chase 30 and move the turtle carrying the chase into proper position against the gauge bar 39 and under the overhanging brackets 36 and 38 whereupon by proper manipulation by the foot lever 22 the floating frame may be lowered so that the lower ends of the adjusting screws 37 enga-ge against and securely hold the chase and the turtle on which it is located against movement. u

The. front overhanging brackets 36 are mounted on two parallel cross rods 49 which are spaced apart a short distance and on which short rollers 50 are mounted. A serrated cutting bar 51 is carried by and between the brackets. The paper 52, which is to be lead over the chase and type, is drawn upwardly between the rollers 50 from a roll of paper mounted on a shaft- 53 near the lower front portion of the machine, the shaft being mounted at its ends in supports 54 attached to the Hoor and located between the spaced apart sides of the lower frame. It is evident that the paper may be drawn under neath the cutting bar 51 and over the chase an-d type and after the proof has been printed the paper may be cut 0E against the serrated edge of the cutting bar 51.

A horizontal shaft 55 is mounted for rotation on and between the front end portions of the sides 2 of the upper Hoating frame. Said shaft extends through the sides and is equipped with sprocket wheels 56 adjacent its ends, oneend of the shaft being continued and squared for the reception of a crank whereby the shaft may be manually turned. Endless chains 57 pass around the sprocket wheels 56 and lie along the outer sides of the flo-ating frame extending to the rear and passing around sprocket wheels 58 mounted on short stub shafts which extend through the sides of the oating frame.

In the lengths of the chains 57 vertical end members 59 of aV platen roller carriage are riage, is also equipped with carrying rollers 61a which ride on the upper sides of the sides 2 of the floating frame which serve as tracks for the rollers 61a.

The carriage is completed by cross rods62 which connectthe members 59 of the carriage. On these cross rods directly in front and also back of the roller 61a are other carrying rollers 63 which ride on the upper edges of the sides 2 of the floating frame. The end members 59 extend downwardly along the outer sides of the sides 2, as shown in Fig. 3, and are equipped with other rollers 64 which extend inwardly under track flanges 2a projecting outwardly from the sides 2 of the floating frame. It is evident that by turning the shaft 55, the chains 57 will be actuated in unison and draw the car-V riage with the platen roller back and over the chase and type and, the lower surface or edge of the roller 6l, being in substantially the same plane as the upper sides of the chase and type, the paper will be pressed against the type; It should be noted in this connection that the length of the rplaten roller 6l is less than the distance between the inner sides of the sides of the chase 30 so that the paper is `not pressed against the upper edges of the sides of the chase but is only pressed-against the type.

An inking roller 65 is carried on a horizontal shaft 66 which extends between and is mounted at its ends on the sides 2V of the float-ing frame. The inking roller 65 is mounted forrotation but for no other movement. Y A gear -67 (see Figs. 6 and 7) is secured to the shaft 66 and is in mesh with a cooperating gear 68 fixed on a short shaft 69 which is rotatably and slidably mounted through the adjacent side 2 of the floatingv frame, its inner end having a rotatable mount in a supporting bracket 7 O connected to said side 2. A spring 71 around the shaft 69 normally moves the gear 68 to clutch conneet it with a combined gear sprocket wheel 72 and retaining disc 73 loosely mounted on the shaft 69 between the gear 68 and the side 2 of the floating frame. The edge of the disc 73 enters a recess in the bracket 70 to hold the wheel 72 in place. The shaft 69, at its outer end, is squared to receive a crank and on attaching the crank, if desired, the shaft may be moved inwardly to disconnect the gears 68 and 'T2 whereby the inking roller 65 may be rotated without affecting any of the other mechanism.

A sprocket chain 74 passes around the wheel 7 2 and extends forwardly and upwardly therefrom to and around Aa sprocket wheel 7 5 on the shaft 55. lt is evident that when the shaft is turned manually by attaching the crank at its end there is a si1nultaneous rotation of the inking roller with the movement of the platen roller Gl over the machine.

An endless chain 76 is disposed at the inner side of each of the sides 2 of the floating frame, said chains at their rear ends passing around sprocket wheels 77 mounted near the rear ends of sides 2 and at their front ends around sprocket wheels 78 secured to a cross shaft 7 9 which extends between and is mounted on said sides 2, one end of the shaft 7 9 extending through and beyond the adjacent side 2 and being squared to receive a crank. rl`he chains I6 pass above the rods 49 and their upper runs may then be ydirected downwardly to the sprocket wheels 78 substantially in accordance with the inclination of inwardly extending inclined tracks 8O formed at the inner sides integral with the sides '2 of the lloating frame.

An inking roller carriage is connected with the chains 76 to be moved thereby. Each end of the carriage includes two sections 8l located in longitudinal alignmentand pivotally connected at their adjacent ends. On the sections 8l of the carriage ends rollers 82, to traverse the upper side of said sides 2 and inclined 'tracks 80, are mounted. The free ends of the sections 8l are connected by cross rods 83. vOn these cross rods inking roller supporting members 84, similar to the sections 8l and pivotally connected at their adjacent ends7 are mounted. Gn and between the parts 8l two pairs of inking rollers 85 are disposed and rotatably mounted as best shown in Fig. 2. Ink spreading rollers'86, one for each pair of inking rollers 85,are located above and between each )air of inking rollers and mounted at their ends on the respective parts 84 from which inclined cam members 87 project to engage with the similar cam like ends of the spreading rollers 86 whereby when the rollers 8G are rotated by frictional Contact with the inking rollers 85 they are also simultaneously reciprocated short distances.

lvlieu the type inking rollers 85 are to be inked from the main inking roller G5, the shaft 79 is turned so as to bringthe type inl*- ingroller carriage onto the inclined tracks 80 with the inner rollers of the two pairs of type inking rollers bearing against the surface of the main inking roller 85 as shown in Fig. 5. a'lurning the roller G5 causes a turning of the rollers 85 in contact therewith while the other rollers 85 are driven from the first rollers 85 through the spreading rollers 86 and the ink onthe surface of the main inking roller 65 is carried'to the type inking rollers 85 and through the reciprocatory action of the spreading rollers 86 and type inking rollers 85 are evenly covered on their surfaces with ink.

ln order to hold the type inking carriage against movement during the inking operation one section 8l thereof is provided with an upwardly extending dog 88 with which a latch dog 89 is adapted to engage. The latch dog is on one arm 90 of a bell crank lever which is mounted for pivotal lnovement at 91 on the adjacent side 2 of the machine and has i downwardly extending arm 92 with an outwardly projecting linger engaging portion 93 for the operator to release the latch when the inking operation has been performed and it desired to move the type inking rollers back over the machine to ink the type 3l.

lhe type inking rollers on their rearward movement for the purpose of inking the type 3l must pass over the ends of the chase 80, the upper sides of which are in the same horizontal planevwith the type. In order that ink will not be transferred to the upper sides of the enes of the chase, raised projections or bumps 94 are secured to the upper sides of the sides 2 of the Heating frame for the carriage rollers 82 to ride over and are positioned so that the type inking roller carriage is lifted to raise the type :inking rollers 85 above the ends of the chase b-ut permitting the type inking rollers to come back to lower position when the type 31 is reached thereby keeping the upper sides of the ends of the chase free of ink at all times yet causing the face of the type to be completely inked with the passage of the type inking roller carriage. It will be also noted that the length of the type inking rollers 85 is less than the distance between the inner sides of the sides of the chase so that no ink is applied to the upper sides of the sides of the chase and, therefore, when paper is put over the type and chase and the platen roller carried over the paper to press it against the type, no ink is transferred from the chase to the paper.

This construction of prooi:l press described is one which has proved very practical and successful. The turtles or trucks, ach with a top 26, which may be an imposing table, are very readily rolled into the machine between its sides, quickly secured in proper position and, due to the floating character of the upper frame of the machine on which all of the essential mechanism of the machine is mounted, variations in the heights and levels of the imposing table 26 and the chase and type thereon are automatically taken care of as the floating frame with its mechanism when lowered, is `brought to rest against the upper sides of the chase at its corners when the adjusting screws 37 engage thereagainst. The inking of the inking rollers may be accomplished by itself by engaging the shaft 69 with a crank and pushing the saine inwardly,

` as is desirable when the inking of the type for the llrst proof sheet is to be done. The inking roller carriage is then moved to the rear over the type. Then when the type inking roller carriage is moved back to the position shown in Figs. l and 5, latched in position, by turning the shaft 55 the platen roller is moved back over the paper which in the meantime has been drawn upwardly and over to the rear to cover the inked type and at the same time the type inking rollers 85 are again inked for the next succeeding operation. After the platen roller has performed its function and has beenreturned to the front of the machine, the proof sheet printed is severed by engaging the paper against the serrated knife edge at 5l and thrown upwardly over the sheet metal plate 5, the turtle released and run out of the latch, the next one put in its place and the operation repeated as many times as may be necessary.

The invention is capable of embodiment with many variations in specific detail of construction from that shown in the drawings and is not to be limit-ed specifically thereto. rlfhe invention is `defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.
