PAPER-FOLDING MACHINE.

Specification of Letters Patent.

Patented June 2'7, 1216.

Application filed September 19, 191 1. Serial No. 862,612.

To all whom it may concern:

Be it known thatI, CAsoN A. 13. Tron, a citizen of the United States, and a resident of .Daytona, intlie county of Volu sia and State of F1o'rida,have invented certain new and useful Improvements in Paper-Folding Machines, of which the following is a speciat the same rate at which they are delivered by the press.

A further object of my invention is to provide in a folding machine movable means forming, when in one position, a gage for the edges of the paper sheets delivered to the machine, and forming, when in another position, a guide for the sheets as they pass into the folder.

In the accompanying drawings, Figure l is a side view of portions of a printing press and of a folding machine having applied thereto devices embodying my invention, Fig.2 is a plan view of the receiving mechanism of the folding machine, Fig. 3 is a detail sideview, partly in vertical section, of the receiving mechanism, Fig. 41 is an end'view of the same, and Fig. 5 is a detail end view of oneof the adjustable stop-blocks for gaging the position of the folding machine relatively to the deliverytable of the press. a I

My invention is especially adapted for use on a folding machine of the general character shown in the patent to Sigafoos, No. 1,056,223, issued March 18, 1913, wherein the frame of the machine is mounted on a base 1 provided with casters 2 so that it may be easily moved about, and in which the frame 3, which carries the actual folding mechanism, may be adjusted vertically to various heights from the floor. My receiving mechanism adapts such a folding machine for use with cylinder-presses wherein the printed sheets are placed bya fly, or by a sheet-delivery device, onto. a horizontal delivery-table 4, and in which ordinarily the sheets are accumulated in a plle on said delivery-table, being bunched against a stationary gage disposed at or near the front edge of the delivery-table, by the action of reciprocating joggerboards which engage the sides and rearward edge of the pile of sheets.

The press and folding machine of which portions are represented in Fig. 1, will be understood to be of the character described. In order that the folding machine may be operated in perfect synchronism with the press, it is preferable that the folder be driven from the press, the cylinder-shaft 5 of the press being provided with a sprocketwheel 6 from which a chain 7 extends to a sprocketqvheel 8 on the drive-shaft 9 of the folding machine. A pinion 10 on the shaft 9 meshes with a gear 11 on a transverse shaft 12 which is suitably journaled on the frame 3. In the structure shown, the shaft 12 is operatively connected by bevel gears 13 with a shaft 14: from which various portions of the folding mechanism are actuated. At the top of the frame 3are arms 15 and 16 of which the end portions extend out horizontally, considerablv beyond the shaft 12. In the ends of said arms are journaled the ends of a horizontal roller 17. Tapes or carrier-belts 18 pass around said roller and extend forward horizontally therefrom, being adapted to convey to the folding mechanism the paper sheets received thereon; The roller 17 is driven by a chain 19 which engages a small sprocket-wheel at one end of the roller. The chain 19 is driven by a sprocket-wheel 20 which is carried on the inner end of a stubshaft 21 journaled in the arm 15. On the outer, end of the stub-shaft is a sprocket-wheel 22 from which a chain 23 extends to a sprocketwheel 21 on the dr1ve-shaft 9, so as to be driven thereby.

Above the carrier-belt 18 and slightly in front of the roller 17 is a horizontal rocking-shaft 25 of which the ends are ournaled in UPWELICllY-QIOjQCtiHg lugs on the arms 15 and 16. Near the arm 16 a crank 26 is secured to the rocking-shaft, and from said crank a curved connecting-rod 27 extends to the upper-end of a cam-lever 28 which is fulcrumed on the frame as shown in Fig. 3. A cam 29 on the shaft 12 is adapted to oscillate the cam-lever between the positions 7 considered as being in the horizontal position, are curvedupwardly. On two or more of the fingers there are formed bearings for a shaft 31 which carries two or more disks 32 adapted to engage the roller 17 when the fingers are in the'horizontal position thereof. VVhen' the fingers are in the vertical positions the lower ends thereof extend slightly below the level of the upper portions of the carrier-belts 18, and thus intersect the plane of said belts. \Vhen in the horizontal position, the lower surfaces of the fingers are slightly above and parallel to the carrier-belts.

Stop-blocks 33,0f the form shown in Fig.

7 5, fit slidably on the arms 'and 16 and the front edge of the delivery-table 4, and gage the extent to which the arms 15 and are secured in adjusted positions thereon by means of set-screws 3a. WVhen the press and folding machine are arranged for cooperative action, the said stop-bloeks'engage 16 project over the front portion of the delivery-table. 'A supplementary table 35 is provided, which is laid upon the deliverytable 4:, with the front edge thereof adj oining the roller 17. Said table is of such depth that at the front edge the upper surface thereof is atthe same level as the upper edge of the roller 17, as best shown in Fig. 3.

In the operation of the mechanism, the driving connections of the press and folder are so arranged that the fingers 30 are in the vertical position shown in Fig. 3 at the times when the paper sheets are placed on the delivery-table by the sheet-delivering mechanism of the press. Said fingers 30 at this time serve as frontgages for the paper sheet, which is deposited with the front edge thereof against the vertical faces of the fingers, so that a portion of the sheet near the front edge will rest upon the roller 17 and the carrier-belts, the sheet in this position being represented by the heavy dotted line A in Fig. 3. After the sheet has been deposited in this position, the fingers are turned to the horizontal position thereof, and the disks 32 at the same time press the sheet into engagement with the roller 17. The sheet is thus gripped between said roller and disks so as to be fed forwardly thereby, being supported and carried along by the belts 18. The fingers 30 in turning to the horizontal position tend to smooth and press the sheet down into a uniform plane and prevent curling of the forward edge thereof until said edge has passed beyond the fingers and beneath the guide-rods 36, of which the rear upwardly-curved ends are supported on the transverse bar 37, and which extend forward therefrom above the carrier-belts, as shown.

Now, having described my invention, what I claim and desire to secure by Letters Patent is:

1. In a paper folding machine, horizontal carrierbelts, a rocking-shaft mounted above the" carrier-belts adjacent to the receiving end' thereof, gage fingers carried'jon said shaft and movableby theoscillation thereof from vertical positions intersecting the plane of the belts to horizontalQpos'itions slightly above and parallel withthe' plane of the belts, and pressure-disks carried by the fingers and'adapted tojpre'ss paper sheets toward the "belts when the fingers are in horizontal position.

2. In a paper folding mach1ne,' a mam frame, frame-members having portlons projectinghorizontally beyond one side *of the.

mainframe, a roller mounted on said'members, carrier -belts extending" horizontally from said roller'over the main frame, a rocking-shaft mounted above the belts adjacent to said roller, fingers carried'onsaid shaft and movable thereby 'to"verticalpositions intersecting the plane of the belts and to horizontal position slightly'above the plane of the belts, and pressure-disks revolubly mounted on 'someof said fingers and adapted to coact with the roller when the fingers'are in the horizontal positions.

3. In a folding machine, a frame, a taperoller revolubly mounted at the end thereof, carrier-tapes extending forwardly horizontally from said roller, a rocking-shaft pivoted'above the tapes parallel with and in front of the-tape-roller, a plurality of fingers carried by 'said rocking-shaft, and means for actuating said shaft to move the fingers alternately between vertical and horizontal positions, the fingers being positioned atone side of the shaft so that in' the horizontal position they'will extend beneath the same in a. plane between the tapes and the axis'of the shaft and with oneend above the tape-roller and the other end infront of the axis of the shaftfwhereby in 'moving from the'horizontal to the vertical positions theends of the fingers'above the tape-roller swing up forwardly and leave the space above the tape-rollerunobstructed, while the other'ends of the fingers swing down rearwvajrdly and intersect the plane of the tapes.

4. In a paper folding mach 1ne,a frame, a tape-roller revolubly mounted at the end thereof, carrier-tapes extending forward horizontally from' said roller, a rockingshaft pivoted above the tapes parallel with *and in front of the 'tape rol1er,'a plurality of fingers carried by said rockingshaft, means for actuating said shaft to move the fingers alternately between vertical and horizontal positions, the fingers being positioned at one side of the shaft so that in the horizontal position they will extend beneath the same in a plane between the tapes and the axis of the shaft and with one end above 'the tape-roller and the other end in front of the axis of the shaft, whereby in moving from the horizontal to the vertical positions the ends of the fingers above the tape-roller swing up forwardly and leave the space above the tape-roller unobstructed, while the other ends of the fingers swing down rearwardly and intersect the plane of the tapes, and pressure-rollers carried by the fingers in fixed axial relation thereto and adapted to cooperate with the tape-roller when the fingers are in horizontal position.

In testimony whereof I have hereunto subscribed myname in the presence of two witnesses.
