Y., assignor to Willard Manufacturing Corporation, New York, N. Y., a corporation of New York Application August 26, 1936, Serial No. 98,089 2 Claims. (Cl. 2'71-~59) This invention relates generally to side guide mechanism for printingpresses, and particularly to ‘a sheet registering device for controlling the being in vertical alinement with one another. The power shaft 6 will be connected in any suit able manner (not shown) with some movable position of paper as it is fed into a lithograph or 5 printing press. The invention consists generally in the ar rangement of guide mechanism at the feed end of the press for accurately registering‘ paper fed to the press and capable of being quickly, easily part of the: press so as to rotate when the press is in motion, while the shaft 1 will be suitably associated with some ‘part of the timing mecha nism of the press feed so ‘as to oscillate at proper and conveniently operated to change its position intervals. The means by which this may be ac complished, being well known and understood, it is deemed unnecessary here to show or de either while the press is in operation or at rest. The invention consists. further in the arrange ment of a carriage or carriages at the sides of the press having mechanism thereon, operated 15 from the press for feeding the sheet to the stop mechanism, and also means operated from the paper feed mechanism for instantly releasing the‘ paper from the guide at the proper time. The invention is carried out by means of the 20 mechanism hereinafter described and claimed and a preferred embodiment of which is illus trated in the drawing, wherein: Figure 1 is a fragmentary front elevation showing one of the side guides at the feed end The registering means includes a carriage 9 supported by the said shafts and feed screw and capable of traveling longitudinally thereon. This carriage includes a table It so positioned as to receive and support an edge or side of the sheet gear l3 travels with the carriage and is keyed or 25 splined as at 14 to the power shaft 6. The power roller 5 i has its upper periphery disposed substan shown in Figure 1, and Figure 3 is a sectional view taken substantially upon line 3--3 of Figure 1. The improved guide or registering device is 30 tially in the plane of the table l0 so as to con The guide receives the sheets advanced to the cylinder and automatically guides them into such position as to be properly and accurately pre sented to the gripper mechanism of the cylin der. Should it be required that the adjustment be changed, such change may be readily accom plished either while the machine is in operation or at rest, and from a position at the side of the machine and convenient to the press operator. In accomplishing these general results, there may be provided a carriage including feed mechanism 45 for one or both sides of the sheet to be fed to the press, and while but one of such feed devices - is here disclosed, it will be understood that the mechanism to be described may be duplicated if desired at the opposite side of the press. Arranged parallel with the cylinder at the feed 50 end of the press is a shaft or track member 5, a power shaft 6, an oscillatory shaft 1 and a feed screw 8. These members are all arranged parallel with one another and relatively close to 55 gether, the power and oscillatory shafts 6 and l 151 to be fed to the press, the said table being usually arranged in horizontal alinement with the upper periphery of the'cylinder 4. The carriage 9 has associated therewith a power roller H with its 20 axis disposed at right angles to the axis of power shaft 6. The said roller receives its power through beveled gears I2 and 13 connected to the roller and the shaft 6 respectively. The 25 of a printing or lithograph press, Figure 2 is a top plan view of the device as arranged in advance of the cylinder 4 of a con ventional form of press and may or may not be associated with the usual feed board (not shown) . it scribe such power connections. tact with the lower surface of a sheet l5 resting upon the said table. The carriage has a post or stop It extending upwardly therefrom and to the upper end of which an arm I’! is pivoted as at l8. The arm, thus pivoted intermediate its ends, is capable of rocking upon the supporting post so that the 35 yoked end I9 is moved toward or- away from the table it. This yoked end of the arm carries an idler 2t adapted when in its lower position to engage the upper surface of a sheet 15 and to move the sheet into frictional contact with the 40 underlying power roller ll. When so engaged, the direction of rotation of the said roller being as indicated by the arr-ow in Figure 1, the sheet i5 will be caused to move laterally until it con tacts the stop or post I6. The yoked end of arm 45 it may be equipped with a plate 2| to prevent buckling of the sheet. The opposite end of arm I1 is pivotally con nected as at 22 to the upper end of a pin or rod 23, the latter being threaded as shown to carry 50 adjusting nuts 24 and 25. A ?nger 26 keyed or splined as at M to the shaft 1 has its outer end engaged with nut 25 of the pin or shank 23, and an expansion spring 28 encircling the said shank is engaged between the finger and the upper 55 2 2,127,292 clamp nut 24. It is obvious, therefore, that the tension of the spring 28 may be accurately ad justed by manipulation of the nut 24. The feed screw 8 has suitable bearing at its ends in the frame 29 of the printing machine, and is equipped with a hand crank 30 by means of which it may be manually rotated. Opera tion of the hand crank causes the feed screw to be rotated, moving the carriage and its asso 10 ciated mechanism in a direction determined by the direction of rotation of the screw. Such an adjustment permits of accurate setting of the carriage so that a proper registry may be at tained. 15 In operation, the timing shaft 1 oscillates so as to move the ?nger 26 downwardly, causing arm l1 to rock upon its pivot and move the idler 20 out of the path of travel of a sheet fed to the table II], as shown by dotted lines in Figure 1. 20 As soon as the sheet engages the table, the shaft 1 assumes normal position, whereupon the idler drops and moves into sheet engaging or clamp ing position above the power roller I I. As the latter is constantly rotating, the sheet is gripped 25 and is moved laterally upon the table It! until the side of the sheet engages the stop or post IE, it being understood that the position of such stop or post properly de?nes the lateral margin of the sheet. The timing mechanism is also oper 30 ated to move the idler 20 out of contact with the sheet as soon as the cylinder 4 arrives at the proper position for taking the sheet, so that the latter is free to move from the registering device immediately this occurs. The adjusting nut 24 35 enables the tension to be adjusted to compensate for different weights of paper stock fed to the press. From the foregoing it is apparent that I have provided an extremely simple side guide and yet one which is capable of most accurate adjust ment and easy and convenient of access by an operator. The construction and arrangement of the guide is such that adjustments maybe made at any time Without stopping or slowing down the press. Having thus described my invention, what I claim is: 1. In a sheet registering device, a power roller adapted to be engaged by a sheet, an arm piv oted adjacent to said roller, an idler carried by 1O said arm and adapted to move in paper clamping engagement with said roller, a pin connected to said arm, a ?nger having an opening in one end to- loosely receive said pin, an adjusting member on said pin, a spring interposed between said ?n 15 ger and said member, a nut on said pin engaging the ?nger on the side opposite to said spring, and a timing device controlling the movements of said ?nger. 2. In a sheet registering device for printing 20 machines, a carriage associated with said ma chine and movable laterally of the path of travel of a sheet in said machine, a stop on said car riage, a power roller on said carriage adapted to be engaged by the sheet in its travel, an arm 25 pivoted upon said carriage, an idler carried by said arm and adapted to move in paper clamping engagement with said power roller, a pin con nected to said arm, a ?nger, said ?nger having b: O an opening therein to receive said pin, an adjust ing member on said pin, an expansion spring encircling said pin and interposed between said ?nger and said adjusting member, a nut on said pin engaging said ?nger on the side of the lat ter opposite to said spring, and a timing device controlling the movements of said ?nger.
