Specification of Letters Patent.

Patented July 27, 1915.

Application filed July 6, 1914. Serial No. 849,191.

To all whom it may concern Be it known that I, CHARLES DowNnY LYON, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Apparatus for Supplying Paper to Printing-Presses, of which the following is a specification.

In printing establishments, whenever it is necessary to replenish the feed-board of a printing-press with paper, it is customary for the pressfeeder to do so, which necessitates him going down from his platform to procure a quantity of paper near his machine or elsewhere, then carrying the paper up to his platform, and placing same in position upon the feed-board, all of which consumes much of the press-feeders time. This objectionable feature is obviated by the present invention which has for its primary object to provide an improved apparatus for replenishing a printing-press with paper, whereby it is unnecessary for the pressfeeder to stop his work or to leave his platform.

With this object in view, the present in vention consists in the provision of an improved apparatus .for accomplishing the desired purpose, which includes an apparatus for hoisting a roll of paper to the feed boa rd, and an apparatus for supporting the roll of paper at or adjacent to the rear end of the feed-board, the supporting apparatus being adapted not only to support the roll of paper and to keep same in a roll, but, also, when operated by the pressfeeder, to shift the roll of paper forwardly upon the feed-board and subsequently to unroll same.

Further, the present invention consists of the novel features of construction and arrangement of parts hereinafter more fully described and pointed out in the claims.

In the accompanying drawings forming wart of this specification in which like numlGl'S of reference denote like parts whenever they occur, Figure 1 is a rear elevation of a printing-press, showing an apparatus embodying the present invention in conjunction therewith; Fig. 2 is a rear elevation of the printing-press, showing the paper supporting and. unrolling apparatus in conjunction therewith; Fig. 3 is a fragmentary side elevation of same, showing a roll of paper held by the supporting apparatus; Fig. 4: is a similar view, showing the roll. of, paper in the position to which same is shifted forwardly on the feed-board preparatory to being unrolled; Fig. 5 is a perspective view of one of the paper supporting brackets; Figs. 6 and 7 are side and rear elevations, respectively, of the paper supporting and unrolling apparatus, showing an alternate form of means for operating same; Fig. 8 is a rear elevation of the device forsupporting the roll of paper while same is being elevated to the feedboard; Fig. 9 is an end elevation of same; and Figs. 10 and 11 are detail views of one of the latches carried by the paper supporting device.

The apparatus of this invention consists of the hoisting apparatus and the paper supporting and unrolling apparatus described as follows:

The hoisting apparatus-This apparatus consists of a carriage 1 of suitable construction, the same being adapted to travel on a track 2 and having a motor 3, preferably of an electric type, mounted thereon. The track 2 is supported from the ceiling 4: or other suitable support or supports by hangers 5 or other suitable means and is arranged to extend over the rear ends of all the printing-presses 6 so' that the carriage can be moved to a position above any one of the printing-presses. A shaft 7, which is revolubly mounted on the carriage 1, bears a drum or pulley 8 or a plurality of suchdrums or pulleys, and is operatively connected with the shaft 9 of the motor 3 through the medium of a worm 10 and worm-gear 11 or other suitable means, so as to receive its power from the motor. For the purpose of illustration, a pair of drums 8 is shown mounted on the shaft 7, each of the former having the upper end of a flexible element 12, such, for example, as a Wire rope or the like, fastened thereto and wound.

thereon. The lower ends of the flexible elements 12 are secured to a bar or rod 13, preferably adjacent to the ends of the latter, there being, also, a pair of bands or straps 14 secured to said bar ,or rod preferably adjacent to the ends thereof.

Each band 1 1 is preferably connected intermediate its ends to the bar 13, leaving the lower end of the former preferably longer than its upper end and free to be passed around a roll of paper 15 in the manner hereinafter described. One end of said band 14 bears a ring 16 or the like and the other end thereof bears a device 1? by means of which said ring is releasably held after the lower end of the band has been passed around a roll of paper 15 toform a loop in which said roll is supported while being hoisted to the paper supporting and unrollingv apparatus. This device 17, as illustrated in"Fi'gs. 10 and 11, may consist of a body portion 18, which is riveted or otherwise secured to an end of the band 14 and to which a latch 19 is preferably pivotally attached at 20. spring 21 is arranged to exert its pressurev against a projection 22 borne by the latch 19 and thereby to hold said projection in engagement with a stop-pin 23, so as to hold the nose 24 of said latch normally inposition to engage and hold the free end of'a bolt 25 and to retain said bolt in approximately an upright position, thereby to prevent, the ring 16 from sliding off the bolt 25 after having been booked over said bolt, which is pivoted at 26 to the body portion. An arm 27 borne .by'the latch 19 affords a means for rocking the latch to cause the latter to release the free end of the bolt 25, whereupon said bolt rocks downwardly and allows the ring 16 to slide off same, a cord 28 or the like being connected to said arm to afl'orda means for actuating same. The cords 28 that are connected to the two latches19, are preferably connected to a cord 29 so that, when the latter is pulled, both latches will-be actuated to release their co-V operatingbolts 25 simultaneously.

In order to prevent the outer edge of the sheets of paper in a roll 15 from flopping about and becoming torn or folded, each band 1ft may be provided with a spacer 30, which has a concaved end 31 adapted to fit against the convex surface of the roll, and a convexed end 32 adapted to fit against the concave side of the innermost sheet of paper adjacent to the outer edge of the latter,

1 thereby' to hold the outer edges of the sheets of paper in spaced relation to the body portion of the roll and, also, against the bands 14, as shown in Fig. 9, said spacer being suspended from the band 14: by a strap or cord :33 or, other suitable means.

Thepaper is loaded on a truck 34 or other suitable conveyance so that the sheets lie flatly in a pile on the latter, and the truck is moved to a position in the rear of the j printing-press, as shown in Fig. 1. When it desired to raise a roll of paper to the paper, supporting and unrolling apparatus of the printing-press, the pressv supplier moves the carriage 1 along the track 2 to a position over .the'rear end of the printingpress, as depicted'in Fig. 1,-by pulling same with the flexible elements 12 or in any other ner. The resssupplier then makes a ll 1519 qu y of s e of p pe at thetop of the pile on the truck 34, and p ass esrthelower ends ofthebands it underear the 11. 1 rmi loops to pp said roll and then hooking the rings 16 on the bolts 25 and rocking the latter upwardly until their free ends are caught and held in approximately an upright position by their coiiperating latches 19, after which the spacers 30 are placed in their proper positions to prevent the outer edges of the sheets of paper from becoming torn or folded. The press supplier then sets the motor 3 in operation by means of any well known remote control system of connections (not shown) to cause said motor to rotate the shaft 7 in the proper direction to cause the flexible elements 12 to wind on the drums 8, thereby raising the bar 13 and the bands 14, which, in turn, raise the roll 15 to a position above the paper supporting and unrolling apparatus, whereupon the motor is stopped and its direction of rotation rcversed to allow the flexible members 12 to unwind from the drums S, in order to lower the roll 15 sufliciently to deposit same upon the paper supporting and unrolling apparatus. After the paper supporting and unrolling apparatus is set in condition to hold the roll 15, the cord 29 is pulled, causing the cords 28 to actuate the latches 19, which, in turn, release the bolts 25 and thereby allow the rings 16 to become detached from said bolts, after which the bar 13 can be raised as hereinabove described to ren'iove the bands 14 and the spacers 30 from engagement with the roll 15, leaving the latter held by the paper supporting and unrolling apparatus and the outer edges of the sheets of paper extending forwardly over the rear end of the feed-board 35 of the printing-press. The press supplier then moves the carriage 1 and the truck 35 to another printing-press that requires a roll of paper in its paper supporting and unrolling apparatus and repeats the operations hereinabove described.

It should be understood that while it is preferable to use an electric motor 3 to operate the shaft 7 for the purpose of raising and lowering the bar 13 and the bands 14:, yet, if desired, said motor may be dispensed with and the shaft 7 may be operated by any other suitable power device, such, for example, as a chain-hoist or the like (not shown in the drawings).

The paper supporting and unrolling apparatus.This apparatus preferably consists of a pair of supporting members 36,

which members are bolted or otherwise secured to the frame 37 of the printing-press 6 at the sides of the latter and extend beyond the rear end of the feed-board 35, a shaft 38, which extends transversely of the rear end of the printing-press, being journaled in bearings in the rear ends of said members. The shaft 38 bears an arm 39 or a plurality of such arms and, also, a pair of arms 40, the arms 40 being preferably located at or adjacent to the ends of said shaft and the arm or arms 39 being located intermediate the arms 40. Preferably, three arms 39 are rigidly mounted on the shaft 38 and are arranged in spaced relation directly behind the rear end of the feed-board 35. Each arm 39 is preferably arcuated to extend upwardly and forwardly from the shaft 38 andhas the rear end of a shoe 41 pivotally attached to the free end thereof by a pin 42 or other suitable means. The forward end of said shoe rests normally on the rear end of a bracket 43, which is secured to the rear end of the feed-board 35 by a bolt 44 or other suitable means, there being preferably as many brackets 43 as arms 39 and said brackets being located directly in front of the arms 39, respectively. The rear end portion of each bracket 43 extends beyond the rear end of the feed-board and slopes upwardly, being preferably bifurcated so that, when the shaft 38 is rocked in the manner hereinafter described to move the arms 39 forwardly, each arm 39 will pass between the prongs 45 of the bracket 43 directly in front of same. Said bracket 43 has a wedge-shaped portion 46, which extends forwardly a short distance upon the feed-board 35, the upper surface 47 of this wedge-shaped portion being arranged to slope upwardly and rearwardly, making an obtuse angle with the sloping upper surface of each prong 45, in which obtuse angle the roll 15 of paperis deposited in the manner hereinabove described, so that said roll will rest partly upon the prongs 45 and partly upon the sloping surface 47 I as best seen in Fig. 3. The front of each shoe 41 is preferably concave as indicated at 48 to conform approximately to the curvature of the roll 15 as depicted in Figs. 3 and 4.

A shaft 49 connects the shoes 41 and is revolubly supported thereby, each end of the former bearing a handle or arm 50,

which affords a means for rocking same.

Said shaft 49 has a plurality of arcuate hook-like arms 51 rigidly mounted thereon, said arms preferably corresponding in numher to the shoes 41 and being located in substantially the same Vertical planes there with. The end of each arm 51 that is secured to the shaft 49 is preferably bifurcated and arranged so that the prongs 52 thereof straddle the shoe 41 in the same plane therewith. By this arrangement, when the shaft 49 is rocked to move the arms 51 rearwardly, the back of the arms 51 will not only engage the tops of the shoes 41, respectively, and thereby limit such rearward movement, but, also, will rest upon the tops of said shoes, so as to stand substantially upright, as depicted in dotted lines, Fig. 6, to allow a roll 15 of paper to be deposited upon the brackets 43 as hereinabove described. Immediately after a roll 15 of paper has been deposited upon the brackets 43 and before the ends of the bands 14 have been detached to re lease said roll, the shaft 49 is rocked by means of either of the handles 50 thereon to move the arms 51 forwardly, causing the latter to hook over the roll 15 without engaging the outer edges of the paper. When the bands 14 are removed from the roll 15 as hereinabove described, the outer edges of the paper fall forwardly upon the sloping surfaces 47 of the brackets 43, and the arms 51 retain the remaining portions of the sheets in the roll 15, as shown in Fig. 3, upon the brackets 43, where said roll remains until the shaft 38 is rocked by the press-feeder in the manner hereinafter described to move the arms 39 forwardly. Forward movement of the arms 39 slides the shoes 41 forwardly upon the brackets 43 and thereby causes the shoes 41 to move the roll 15 forwardly to approximately a position shown in dotted lines, Fig. 4, during which movement the arms 51 prevent the roll from rolling. Reverse movement of the shaft 38 moves the arms 39 and the shoes 41 rearwardly to their normal position, causing the arms 50 to unroll or nearly unroll the paper (depending upon the length of the paper), after which the press-feeder adjusts the paper in its proper position on the feed-board.

As a means for rocking the shaft 38, a pair of reciprocatory members 53 is pro vided, said members being reciprocatively supported in guides 54 borne by the members 36. The rear end of eachmember extends beyond the rear end of the feedboard 35 and is preferably bifurcated to. receive the end of an arm 51. between its prongs 55, the latter being connected by a pin 56 which extends through a slot 57 in said arm. Each member 53 is adapted to reciprocate forwardly and rearwardly of the machine and is held normally in and returned to its rearmost position by means of a spring 58, the rearward movement of said member being limited by the engagement of the enlarged forward end 59 thereof with a guide 54, as depicted in Fig. 3. The enlarged forward end 59 of said member 53 bears a pin 60 which projects into a slot 61 in an arm 62 of a bell-crank 63, which is mounted on a pin 64, the v ported. in the frame 37 of the printing-press and, also, in a bracket 65, which is bolted or otherwise secured to said frame. The other arm 66 of said bell-crank is pivotally eon neoted at 67 to the upper end of a depress].- ble link 68, which bears a foot-lever 69, by means of which same may be operated by the foot of the press-feeder, the lower end ofsa-id linlrbeing pivotally connected at 70 to an. arm 7 borne by the shaft 72; The

latter being supshaft 72 is arranged to extend transversely of the rear end of the machine and is journaled in bearings 73, which are bolted or otherwise secured to the frame 37 of the machine. By reason of duplicating the arm 4.0, member 53, spring 58, bell-crank 63, link 68, and arm 71 at the sides of the machine, the press-feeder can effect the operation of the shaft 38 from either side of the machine while standing on the platform 74 adjacent thereto, and'the power applied to the arms 40 on shaft 38 is equalized.

Whenever the feed-board requires more paper, the press-feeder, while standing on either platform 74: of his machine, presses downwardly with his foot upon the footlever 69 near him, whereby the link 68 bear- I ing said foot-lever descends and causes the arm 71 connected thereto to rock the shaft 72 counterclockwise, Fig. 3, with the result that the other arm 71 borne by shaft 72 draws the other link 68 downwardly. This rocks both bell-cranks 63 in the direction to. cause their arms 62 to move the members 53 forwardly, causing the arms 40 to rock the shaft 38 in the direction to cause the arms 39 to shift the roll 15 of paper forwardly, as hereinabove described, until said members 53 reach the limit of their forward movement, which occurs when the bifur cated end of said members 53 engage the rearmost guides 54, as shown in Fig. 4. The press-feeder then releases the depressed foot-lever (i9 and thereby allows the springs 58 to restore the members 53 and parts connected therewith to their initial position,

whereby the arms 51 unroll or nearly unroll the sheets of paper in said roll 15, after which the pressfeeder shifts the paper to its proper position on the feed-board and continues to feed the press. In this way, the press-feeder replenishes the feed-board with paper in a relatively shorter time than heretofore and without the necessity of leaving his platform.

If desired, he foot-power mechanism fol rocking the bell-cranks 63 may be dispensed with anda hand-power mechanism of any suitable construction, such, for example as depicted in Figs. 6 and 7, may be substituted therefor. In this event, the pins 6-'.-; and brackets 65 are omitted entirely, and the bell-cranks 63 are rigidly mounted on a shaft'75, the latter extending transversely of the rear end ofthe machine and being journaled in the frame 37. The arm 66 of each bell-crank 63 is made longer and has a handle 76 secured thereto to afford a means for rocking the shaft 75, thereby to actuate the members 53 as hereinabove described. Furthermore, if desired, any suitable electric or other power device (not shown) may be employed to effect the rocking of the shaft 38 for the purpose hereinabove de scribed. g i v Various changes in the details of construction and arrangement of parts may be made without departing from the nature and spirit of the present invention.
