Application filed February 16, 1915. Serial No. 8,692.

To all whom it may concern:

Be it known that I, JAMES G. HARDIE, a citizen of the United States of America, residing at Canton, in the county of St. Lawrence and State of New York, have invented certain new and useful Improvements in Paper-Loading Machines, of which the following is a specification.

The present invention relates to that which may be called a continuous, paperloading machine, because the stock of paper is placed, at intervals, upon this machine, by which it is carried forwardly so that the printing press is kept continuously running.

The object of this invention is to furnish mechanism that will permit of the stock of paper to be rolled out and placed in such a manner that the stock will constitute one continuous bank of sheets, so shingled out that the sheets will move forwardly in the most convenient form to be manually fed to a printing press, or to any other machine to which single sheets are fed.

The accompanying illustrations show the invention mounted upon the feed table of a printing press, although it is applicable to any other form of machine to which sheets are singly fed.

The invention consists mainly of a suitable frame-work rigidly fastened to the printing press table, and having a main table mounted upon said frame-work, upon whichthe stock of paper is placed when rolled out. Around this table and over a main roll belts are passed which carry forwardly the bank of sheets. Between the main table and the press table is an inclined sub-table around which are passed belts which receive the bank of paper carrying it down to the press table; also around a certain portion of the press table are belts which advance the bank of sheets to the desired position. Suitably placed beneath the upper table is an electric motor, suitably belted and geared to the main belt roll. An

electric switch is suitably placed nearthe operator and by operating the switch the motor is started, which has the effect of moving forwardly the entire bank of paper.

The invention includes other features of novelty, in addition to those above described, which will be included in the description of the accompanying drawings and included in the annexed claims.

Figure 1 is a side elevation showing the invention in position, on the table of a printing press, and the various sets of belts which carry the stock of paper forward; also a stock of paper is shown on the main table in the rolled-out position. The motor is shown attached to the under side of the main table, in operative connection with the main belt roll, which consists of a flexible belt and then a train of gears; also a diagrammatic view of the electric wiring with the switch in place. Conveniently near the operators chair is shown a tripping mechanism. Fig. 2 is a transverse, sectional view of the invention, on a larger scale than Fig. 1. Fig. 3 is a plan View of the invention showing the belts passing above the table and around the main belt roll; also the electric motor shown dotted beneath the table. Fig. 4 is a side elevation of the gearing. In the accompanying drawings, similar figures refer to similarparts throughout.

Fig. 1, A is the rear portion of a printing press showing the impression cylinder and the table in position; 1 is the side-frame of the loader and is rigidly fastened upon the press table 2; 3 is the electric motor; 4 and 5 are the wires which supply current to the motor; 6 is the switch for starting and stopping the motor; 7 is a belt passing around a pulley on the motor and around a pulley 8, on the shaft 9, and between shaft 9 and the shaft 10 is a train of gears, shown in Fig. 4. which transmits motion to the main roll 11; mounted upon the frame, 1, is the table 12; 13 are rolls pivoted to the table; 14: are belts passing around the rolls 13, the main roll, 11, and over the tightener roll 15; 16 is a side guide against which is placed thestack of paper 17. Upon the stack of paper rests the idle roll, 18, which is pivotally attached to the frame 1, by the link 19; 20 is a guide to turn the stock of paper in the direction of the second set of belts 21, which pass around the rolls, 22, upon the shaft 23; 24

is a gear, rigid upon the shaft 23, and is in operative connection with the gear 27, on the shaft 10, through the intermediate pinions 25 and 26; 28 is a sub-table placed in the frame-work, 1,0bliquely to the press table, and are pulleys 1ournaled in the press table; above and below the these pulleys, are passed the belts 31; 32 is the operators chair; 33 is means for tripping the press cylinder.

Fig. 2 shows the friction shoe 34, which normally rests upon the bank of paper to supporting the'belts 21; 29 and 30 press table, and around prevent the paper sliding down the inclined table 28; the shoe is pivotally attached to the shaft 36, by the link 35.

Fig. 3 is a plan view showing the table 12, the belts 14 passing around the pulleys 13 and the main roll 11, with the idler 18 resting upon the belts 13 and held in place by the link 19.

Fig. 4 is a side elevation of the gearing. The belt pulley 8 is rigid upon the shaft 9 which carries the pinion 37 which engages the gear 38, upon the shaft 40, which shaft also carries the pinion 39 which is in en gagement with the gear 41, upon the shaft 42, which carries the pinion 43 in engagement with the gear 27 upon the main roll shaft 10.

Thus, in the operation of my invention, the stock of paper is rolled out and placed upon the belts 14 which are supported by the table 12. The operator sits upon the chair 32, and whenever it is desired to move forwardly the stock of paper to a convenient position to feed the sheets to the cylinder, the operator presses the knob of the snap-switch 6, which starts the motor 3, which imparts motion to the main roll, 11, through the belt 7 and the accompanying train of gears located between the belt pulley 8 and the main gear 27. This has the effect of propelling the belts, 14, which carry the bank of paper forward and under the idler, 18, and the guide, 20, turns the front edge of the bank of paper forward and upon the second set of belts 21. The belts 21 are propelled by a train of gears located between the shaft 23 and the gear 27. The shoe, 34, rests upon the bank of paper and prevents the paper from sliding down the inclined table 28. Upon the shaft, 44, are placed the pulleys 29 and 45, through which motion is imparted to the belts 31, advancing the bank of paper as may be desired.

I have illustrated and described my invention as mounted upon a printing press, but I do not wish to be confined to a printing press only but wish to use it on any machine to which it is adapted.

In the construction of my invention, when reduced to practice, it is necessary that the table 12 be sufficiently elevated above the press-table to admit of an operator looking across the press and below the upper table, to see the side guide on the opposite side of the presstable; but this construction will locate the main feed-roll 11 in an elevated position, above the press-table; and will, therefore, necessarily require means to carry the bank of paper down the steep incline to the press-table. Various forms of means can be used for this purpose, and although I have shown a stationary, inclined table with belts passing around it, I do not confine myself to this particular means, but wish to use any suitable means to carry the sheets from the main roll 1.1 to the belts 31 on the press-table.

It is well-known to the trade that sheets of paper must lie flat on the press-table in order to get the most accurate register. To meet this need it is necessary to locate the tape-shaft 44 a predetermined distance from the impression cylinder, which will locate the shaft 44 so far back that a steep. incline is made between the main roll and the shaft 44. To properly retard the sheets, in transit,

down this incline, I use shoes which rest upon the stock; the weight of the shoes may be varied to suit the grade of paper being fed. The means, however, of carrying and retarding the stock, in transit, may be varied in form without departing from my invention; hence I do not confine myself to the particular form of means shown, but wish to use whatever means will accomplish this end.

Having thus described my invention that which I claim is:

1. The combination in a loading machine of a frame mounted upon a printing presstable, a table mounted upon said frame, a power-driven main roll journaled in said frame, belts passing around said main roll and said table, power-rotated pulleys journaled in said press-table, belts passing around said pulleys above and below said press-table, a power-rotated shaft journaled in said frame, pulleys mounted upon said shaft, belts passing around said pulleys and around said pulleys in said press-table, a suitable member adapted to guide a sheet from the main roll to said belts.

2. The combination in a loading machine of a frame mounted upon a printing presstable, a table mounted upon said frame, a power-driven main roll journaled in said frame, belts passing around said main roll and said table, power-rotated pulleys journaled in said press-table, belts passing around said pulleys above and below said press-table, a table interposed between said main roll and said printing press-table, a power-rotated shaft journaled in said frame, pulleys mounted upon said shaft, belts passing around said pulleys and around said interposed table.
