PRINTER/S LINE-UP TABLE.

My invention relates to and register tables adapte for inspecting 'proof sheets to determine the alinement thereof, and for lining up blank sheets or preparing strike sheets, etc., and its object is to improve and simplify devices of this kind in the manner hereinafter more fully set forth.- y

Y My invention comprises a table having a transparent top with illuminating devices arranged under the Same so that proof sheets placed on said table can be inspected for precise alinement, a plurality of sheet-stops arranged at the forward edge of the table, with each of which stops a sheet gripper is associated, and two alining bars arranged at right angles to each other and mounted for transverse and longitudinal movement across the table without change in their angular relation, one of said bars being disposed parallel to a line connecting the forward ends of said stops. Preferably the sheet-stops are maintained in contact with the table by resilient means which co-operate with the sheet grippers to raise the same above the table, a cam lever or the like being provided for depressing the gripper after a sheet has been placed on the table.

My invention comprises also an arrangement of cams or other suitable members whereby each of said bars may be elevated above said table by moving the same at right angles to its direction of movement across the table.

A marking device may be mounted on each bar and arranged for movement longitudinally of the same. means being provided for adjusting such device vertically.

f Fig. 14 is a plan view of the marking device shown in Fig, 13. i

In the particular drawings selected for more fully disclosing the principle of my invention represents a table having a transparent top 21 illuminated from beneath by the electric lamps 22, said' top being designed to receive proof sheets of large size on which are arranged series of printed units such as a number of pages of a book which are to be printed simultaneously and which it is required to place in precise alinement with one another so that when cut and trimmed, the marginal edges of all the pages will be uniform.

Mounted on the channel 23 carried by the framework of the table, are a plurality of combined sheet-stops and rgrippers 24, 24, two such devices being shown in the present instance, and each consisting of a frame formed of the side bars 25, 25, and the top plate 26 secured thereto by the rivets 27, 27, or other suitable means, said frame conv stituting a housing for the sheet-stop fin er 28 and the sheet-gripping finger 29, wh1ch are pivotally mounted therein by the stud 30. By means of the springl 31 or other resilient member the sheet-stop finger 28 is normally held in contact with the table and the sheet-gripping finger 29 held above the same, a cam lever 32 pivotally mounted on the plate 26 by the stud 33 serving to deress the finger 29 so that the outer end thereof will clamp the sheet to the transparent top.

Depending from the forward ends of said side bars and attached thereto by the rivets 34, 34 is a flange 34 which co-operates with the under side of said channel 23. A plate 35 of spring material is attached to the rear of said frame by the screws 35 and the lower portion of said plate which extends below the side bars constitutes a. means for holding the said frame rcsiliently against the rear of the channel 23. In the present instance the said plate is slit as indicated at 35, 35" and the end portions thereof below the slits are bent outwardly as indicated at dotted lines at 35 (Fig. 8), the said bent portions taking against the rearward edge of the channel 23.

The side gage 36 is also mounted for movement longitudinally of said channel and comprises the finger 37 pivoted at 38 to the arm 39, which in turn is swivelled by the stud 40 and screw 41 to the plate 42, to the under side of which the flange 43 is .attached by the screw 44. a plate spring 44 maintaining said plate in engagement with said channel. The spring 45 co-operating with one side of the arm 39 and having its free end arranged against a. shoulder 46 maintains said arm in such position that the side gage 37 is normal to the line 47 connecting the outer ends of the sheet-stops, and the said spring limits the movement of said plate in a counter-clockwise direction -while permitting the same to be turned about the stud 40 in the opposite direction. Preferably a plate spring 48 attached to the member 39 is employed to maintain the finger 37 in contact with the transparent top 21.

It will be noted that the combined sheetstops and grippers and also the side gage are movable longitudinally of the table and that each is accurately positioned on the channel 23 and is held in resilient engagement therewith. The rear end of the arm 39 is provided with a. pointer 39 co-operating with the scale 39".

The alining bar 49 is arranged parallel to the line 47 connecting the forward ends of the sheet-stops 28. 28 and is provided with means whereby it may be moved transversely of the table, such means being shown in the present instance as gears 50, 50 meshing with the parallel rac- ks 51, 51, said gears being rigidly connected to the shaft 52 journaled in the blocks 53, 53 and in the hand-piece 54 mounted on said alining bar. One end of said alining bar is provided with a. pointer 55 arranged to travel over the scale 56.

Obviously the racks and pinions 51` 50 will maintain the straight edge in parallelism with the line 47.

In order to place the straight edge on the proof sheet without crumpling the edge thereof, it is desirable to elevate said straight edge slightly above the top 21 hefore moving the same over the sheet. In the present instance I so arrange Amatters that the movement of said alining` bar at right angles to its direction of movement across the table will serve slightly to elevate said bar. l

While various means may be employed for this purpose, I prefer to employ a cam arrangement consisting, as shown, in the upright 57 havingl a bevelled edge arranged to co-operate with the revel'sely bevclled edge 59 formed on the guide member (10, the latter being secured to the block by the bracket 61. At the opposite end of said alining bar is a somewhat similar bracket 62 carrying a cam arranged to (ro-operate with a stationary member to elevate that end of the alining bar, the same distance as the end first mentioned, and it will be noted that such elevation of said bar is effected without disengaging the pinions from their respective racks.

Arranged at right angles to the bar 49 is a bar 63 provided with a hand-piece 64 and gears 65, 65 rigidly attached to the shaft 66 journalled in the bearings 67. 67 and in said hand-piece. said gears meshing with the racks 68, 68, whereby said alining bar may be moved longitudinally of said table without altering its angular relation to the bar 49. Depending from the journals 67 are brackets 69 carrying flanges 70, the under surface of which is bevelled, as shown at 71, and co-operates with the cam surface 72 so that the movement of said alining bar at right angles to its direction of movement across the table will elevate said bar without disengaging the pinions 65 from their racks 68. A pointer 67', attached to the liournal 67, is arranged to travel over the scale 39.

It is to be understood of course that the cam arrangement employed at the righthand end of the bar 63 is similar to that shown and already described in connection with the righthand end of the bar 49. an-d also that the cam members at the lefthand end of the bar 49 are similar to those shown at the lefthand end of the bar 63.

In the use of my improved line-up table a proof-sheet 73 (see Fig. 5) is placed on the table, and its lefthand end alined against the side guide 36, as indicated by the dotted line 74. The forward end thereof is positioned by the sheet- stops 28, 28 which are normally down against the table, and then the. sheet is clamped in position by the cam levers 32 which force the gripping fingers 29 firmly against the sheet. The alining bars are then moved across the sheet to determine the alinement of the units printed thereon. p

In the lining-up operation, it is Sometimes desirable to rule straight lines on the proof sheet along the edge of the alining bars. lVhile a variety of marking devices may be employed for this purpose, I prefer a marking device mounted on and slidable along each straight edge, such device being shown Ile form of marker shown in Figs. 10, 11 and 12 consists of a bevelled wheel 80 of carbon or other suitable marking material rotatably connected to the marker holder by the Screw 81. Within the recess housing the upper portion of the marker wheel is a bevelled scraper 82 maintained against said marker by the spring 83 whereby the edge of the marking wheel is always maintained sharp and pointed. i

By means of the screw 84 threaded to the carriage and also to the marker holder 79 and provided with the knurled head 84', the vertical position of the markingwheel may be varied in a manner that will be obvious, longitudinal movement of said screw being prevented by the top plate 79 and the collar 79".

An alternative form Otmarking device employing an ink reservoir 85 and an inking wheel 86 is shown in Figs. 13 and 14, the ink being supplied to the wheel by the roller 87 gearedv to the said wheel by the gears 88, 88 and receiving its supply of ink by contact with the roller 89.
