PAPER-FEEDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 552,421, dated December 31, 1895.

Application filed December 18, 1894. Serial No. 532,194. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES N. OOMLY, a citizen of the United States, residing at Lebanon, in the county of Warren and State of Ohio, administrator of the estate of JOHN P.

OOMLY, deceased, late of Lebanon, in the county of \Varren and State of Ohio, do hereby declare the following to be a full, clear, and exact description of the invention of the said JOHN P. OOMLY of an Improvement in Automatic Feeding and Registering Machines, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a machine for an- I 5 tomatically feeding and registering single sheets of paper, but more particularly to registering and feeding sheets of paper to a printing-press.

The primary object of the invention,is to provide means whereby a single sheet of paper may be taken from a pile and properly conveyed to the gages of a printing-press or other machine, to provide means for properly registering or aligning the sheet before leav- 2 5 ing the feeding-machine, to provide means whereby uniformity of the margins may be preserved when it is desired to print both sides of the sheet, and to provide means by which the different mechanisms may be oper- 0 ated from a single source of power.

A further object of the invention is to provide a simple, efficient and durable machine which may be used in connection with folding, ruling, envelope and other machines of various designs.

With these and other objects in view the invention consists in the construction and combination of the several parts, as will be more fully hereinafter described, and then more particularly defined in the claims at the end of the description.

Referring to the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation, partly broken away, illus- 4 5 tratin g the machine as applied to a printingpress. Fig. 2 is a plan view. Fig. 3 is afragmental-y sectional elevation on theline III III of Fig. 1 of the paper-lifting mechanism. Fig. 4 is a fragmentary rear elevation of the 5'0 paper-lifting mechanism. Fig. 5 is a side eleing mechanism.

vation of the mechanism illustrated in Figs. 3 and 4. Fig. 6 is a fragmentary view illustrating the means for operating the grippers which convey the sheet after it has been raised from the pile to the registering device. 5 5 Fig. 7 is afragmentary plan view showing the mechanism for raising the sheet off the traveling belts after it has been properly registered. Fig. 8 is a plan view of a modified form of registering or sheet-aligning device, and Fig. 9 is a sectional view on the line IX IX of Fig. 8.

In the drawings, A may designate a frame of any preferred construction provided with suitable bearings in which is journaled the shaft A, to which the press-cylinder A is secured. On the outer end of this shaft is the master gear-wheel a, which engages an intermediate spur-gear ct, which in turn meshes with the gear 60 the latter being secured to the shaft a which extends transversely of the machine and is journaled in the frame A.

The paper B is placed upon a table I), beneath which is arranged a series of springs I), supported upon the seat 12 the said seat being secured to the frame in any approved manner. These springs tend to raise and keep the pile of paper in its proper position, so that a single sheetmay be raised by the lift- This mechanism maybe of So any suitable construction; but it is preferable to employ a series of cylinders or exhausts b which are located at intervals transversely of the machine, and which are suitably supported upon the cross-rod b the latter hav- 8 5 ing depending stems If, which pass through apertures in the frame A. The stems have nuts I) 011 the ends thereof and spiral springs 19 surrounding said stems below the framebeam, which normally press the stems downpend from a cross-rod 0 the said cross-rod 10o being secured to the upper ends of the vertically-movable rods 0 These rods are arranged on opposite sides of the machine and pass through brackets 0' arranged on a portion of the frame, and are provided on their lower ends with antifriction-rollers c, which abut against the edge of the cams c secured to the shaft (1 by which the rods are raised. The springs c which surround the lower ends of the rods serve to keep the rollers in constant contact with the cams and to return the plungers of the exhausts after they have been raised. The rods 0 above the brackets c, are provided with cams or cam-surfaces c which contact with antifriction-rollers ar ranged on the lower ends of bell-crank levers c", which are pivoted to projecting portions c of the frame, the said bell-crank levers being connected at their other ends with the cross-bar b by the pitmen c". It will be seen by this construction that as the plungers are raised to cause a suction in the cylinders to lift the forward edge of a sheet of paper from the pile the cylinders will also be raised, but at a slower speed, and after a partial movement of the plungers, so that the edge of the sheet is not only lifted by the suction created in said cylinders, but is carried by the same a proper distance to be held in position to be conveyed to the registering device.

The sheet being raised from the pile of paper by the action of the exhausts, the rockbar D by means of the leaf (1, which now passes under the edge of the sheet, will hold the same in a raised position and prevent the sheet as it is withdrawn from disturbing the other sheets of the pile. This leaf d is secured to or formed integral with the angular levers (1, which are loosely mounted upon the stay-rod (P, the said bell-crank levers having the arms d arranged in the path of movement of the crossrod 0 which operates the plungers, and are retained in contact therewith by springs (1 The springs d surround and have one of their ends secured to the stay-rod or brace d and their other ends passed under the arms so as to normally raise the leaf cl, while the downward movement of the crossrod c-, caused by the recoil of the springs 0 'will move the rock-bar on its pivot, throwing the leaf out of the path of the next sheet of paper after the one raised has been taken to the registering or aligning device.

As the rock-lever D holds the sheets, the grippers E, comprising the jaws e and e, which are pivotally connected together, grasp the forward. edge of the sheet of paper to remove the same from the pile. The jaw c of each gripper is secured by a set-screw or otherwise to a cross-bar 6 which connects the frames or end pieces E of the carriage E arranged to travel back and forth upon the tracks which are located above and secured to or formed integrally with the frame A. The lower jaw c has its end passed through a cam-slot e of the reciprocating rod 6, wlnch has its ends mounted in the frames of the carriage. This reciprocating rod has a roller e journaled upon the end of said rod and arranged in the path of the cams e and 6 located at the rear and fore parts respectively of the frame and extending outwardly therefrom, whereby the grippers may be closed as the carriage moves rearward to grasp the sheet and opened when moving forward, so that the sheet may be taken from the pile to be properlyregistered. This carriage E may be of any suitable construction, but it is preferable to use the frames E, before referred to, on which are journaled the antifrietional rollers or Wheels 0", which embrace the upper and under sides, respectively, of the tracks 6 and serve to guide the carriage thereon, the said carriage being connected to the master-wheel a and the crank f secured to the shaft A on opposite sides of the machine by the pitmen f by which the said carriage is caused to move back and forth as the shaft A rotates.

For registering or aligning the paper before being taken by the grippers of the press-cylinder there is provided a registering device G, comprising a table G having the side beams g g, secured together by the bars g g, which are of sufficient length to permit said table to reciprocate transversely of the frame, through which the ends of bars g 'g pass. The said table having the shafts (1 9 journaled in the ends of the beams and provided with a series of grooved pulleys g around which are endless belts 9 which tend to convey the sheet forward after the same has beendropped onto the table by the carriage E The shaft 9 of the table is rotated by the gear 9, secured to the outer end of said shaft, which is in mesh with the spur-gear g that in turn meshes with the gear (t the face of the gear g being of sufficient length to permit the table to reciprocate back and forth and yet be constantly rotated. This table is reciproeated by the angular rock-lever II, which has a knuckle-joint or other suitable connection 7b with a bracket h extending outwardly from the frame A. The upper end of the r0cklever is pivotally secured to a stud 76 which passes outwardly from the table G through an aperture in the frame, and has its other end provided with a roller which enters a groove in the double-acting cam h which is secured to the outer end of the shaft (L3, so that as said shaft rotates the lever H will be rocked on its pivot, thereby moving the table according to the direction of the movement of said lever. In the position shown, the table and sheet have moved toward the gage h which is secured to the frame and is adjustably held thereon by the set-screw 7r", the sheet in the meantime being carried forward by the endless belts g to the front gages h h, thereby placing the sheet in its proper position.

\Vhen the sheet arrives at the front and side gages and is properly registered, it is necessary that the sheet should become stationary, and to eifect this plates I are ar-' ranged between the tapes provided with depending arms 1', which are secured to or formed integrally with a shaft 1" j ournaled in and reciprocating with the table G. The shaft t" is provided with depending arms 11 near the opposite ends of' said shaft, which connect, by the pitmen'i to the bell-crank levers 2' pivoted to studs 7? arranged on the table G, the outer end of said bell-crank levers being arranged to contact with the stops 1' depending from the frame, as best shown in plan in Fig. 7. This mechanism is arranged on opposite sides of the machine, so that thesheets will be lifted off the endless tapes or belts g whether the table moves to one side or to the other. At the time the sheets are lifted the gages h are raised in any approved manner, and the grippers 71- of the press-cylinder take the sheet to be printed in the usual and wellknown manner.

The operation of the machine will be readily understood from the foregoing description. It will be seen when the sheets are arranged as shown, and the machine started, that as the plungers of the exhaust or cylinders b are raised, as heretofore explained, the forward edge of the top sheet will be lifted, at which time the rock-bar D will be pressed upwardly by the springs d to hold the sheet in this position. The carriage E by its operating mechanism then moves rearwardly and causes the gripper E to grasp the edge of the paper which is withdrawn from the pile as the carriage moves forward till the roller .6 contacts with the cam 6 This reciprocates the rod 6 oppositely to the other 1novement,thereby opening the gripping-jaws e, causing the sheet to be dropped upon the table G, which is now moving transversely of the machine to the side gage, as the endless belts g carry the sheet forward to the front gages. The sheet is now lifted off the tapes by the plates I and their operating mechanism, and the front gages 77. raised so that the grippers h may take the sheet to be.

printed. After the sheet has been printed on one side it is sometimes desirable to print the same on the other side yet preserving uniformity of the margins. In this case the sheets of paper already printed are turned end for end and placed on the table I) similar to the pile B. The cam 71.3, which is secured to the shaft a by the set-screwh is moved so that the cam-groove h will be engaged by the end of the rock-lever H, and as this groove is oppositely arranged to the other groove of said cam the table G will consequently be reciprocated in the other direction or toward the side gage h carrying the sheets in that direction. The operation of the machine, with the exception of the direction of movement of the table G, is the same as heretofore explained.

Instead of providing a registering device, as G,there maybe used in some instances,such as shown in Figs. 8 and 9. Here the table J is arranged to be placed at different angles, so that the sheet instead of being carried bodily to one side of the machine to be aligned or registered is made to travel obliquely by the belts j to the respective side and front gages. This table has the side beams j,-in which are journaled the pulley-shafts jf; having the tapes 7' passing around said pulleys. The shaft j is pivotally mounted on the end of an upright shaft is and has a miter-gear k in mesh with a similar gear 10 near the upper end of the upright shaft, by which the shaft j is rotated. The table is supported on the frame in any suitable manner, and for this purpose there may be provided an are m extending outwardly from one of the beams of said table which is adapted to be secured to abracket m on the frame when the table is shifted to vary the angle of the same. From the other beam of the table extends a projection provided with a set-screw m which engages the frame according to the position of the table, and further serves to support said table upon the frame. In the position shown in full lines the sheet of paper will travel toward the side gage n and front gages n 01, while if the table should be shifted to the position shown by dotted lines the paper would then travel toward the side gage n andfront gages 71. or. By this arrangement the sheet may be properly registered or aligned and printed on both sides of the sheet, still retaining uniformity of the margins. The sheet of paper may be conveyed to the table by mechanism such as described in the other figures, and the sheet may be raised off the traveling belts by the plates 0, which are connected to averticallymovable rod This rod is operated by the cam 0 secured to the cylinder-shaft and the rock-lever 0 pivoted to the frame, or the said rod may be operated in any other approved manner. The paper in this case is taken from the plates 0 in the manner heretofore described.

The atmospheric exhaustsand pistons may be secured to their respective cross-rods in such manner as to be capable of being moved transversely thereof in order that they may be massed to lift sheets of paper of greater weight, and may be so constructed that two or more can be used in accordance with the size of sheet to be raised. Instead of the exhausts raising and lowering, the pile of paper may be caused to raise and lower by means of cams.

Other means than the pneumatic devices shown may be employed for separating the sheet of paper from the pile, and instead of rock-lever H for reciprocating the registeringtable a bell-crank lever having one of its arms in the path of movement of a vibrating or other movable lever may be employed. Other changes of a substantially like character may be made, if so desired, without departing from the spirit of the invention.
