PAPER-DRYING MACHINE.

SPECIFICATION forming part of Letters Patent No. 633,733, dated September 26, 1899.

Application filed April 27,1899.

1'0 (LZZ whom it may concern Be it known that 1, JOHN A. PRINCE, of New York, (Brooklyn,) county of Kings, and State of New York, have invented new and useful Improvements in Paper-Drying Machines, of which the following is a specification.

This invention relates to a machine for forming the printed, varnished, or painted end of a paper-roll into loops and laying such loops side by side upon a drying-rack. The machine insures a reliable delivery of the supporting-sticks and advances the loops upon the rack by small stages, so that a rapid advance of the loops with a short stroke of the slide is obtained.

In the accompanying drawings, Figure 1 is a side elevation, partly in section, of the machine; Fig. 2, a plan, partly in section, thereof; Fig. 3, a detail side view of part of the rack; Fig. at, a cross-section through the rack, and Fig. 5 a detail of the gearing e f.

The letter a represents a box adapted for the reception of a battery of superposed sticks or slats b, which may be discharged singly through the lower slotted end of the box.

0 c are a pair of parallel feed-chains, the upper run of which is inclined from the bottom upward. The chains 0 describe a triangular course, running over sprocket-wheels c and idlers c 0 of which the wheels 0 are placed below box a, while the wheels 0 are placed directly in front of a pair of parallel rails d.

To each of the chains 0 are secured two (more or less) pairs of noses a which by the movement of the chains traverse the lower open end of box a to engage the lowermost stickb and deliver it upon the ends of the rails d, which are supported by hangers d.

Motion is imparted to the chains 0 from a counter-shaft c, having toothed wheels 6, which engage smaller toothed wheels f, fast on stub-shafts f, carrying the sprocket-wheels 0 Fig. 5. One of these stub-shafts is driven by belt g from power-shaft g. Step-pulleys g f on the shafts g f, respectively, permit the chains 0 to be driven faster or slower, so that the machine may be set for lighter or heavier paper.

The slides for feeding the sticks intermittently along the rails d are constructed as follows: To the inner sides of the hangers cl Serial No. 7l4,640. (No model.)

are secured rolls d upon which are sup ported the reciprocating slide-bars h. These bars are connected at intervals by rods h, to which are attached the longitudinal bars or rails 72/2, to which in turn the pawls h are pivoted, one row of pawls being arranged vertically above each of the rails d. Reciproeating motion is imparted to the slide from wheels c by wrist-pins e pitmen 2', and shaft i, turning in bearings h of bars h.

The forward slide,constructed as described, drives a similarly-constructed rear slide, the stroke of which is about one-half that of the forward slide and the pawls j of which are correspondingly set closer together. The rear slide receives motion from one of the rods h of the forward slide by link 70, lever fulcrumed at U, and link it that engages one of the rods j of the rear slide. The object of the two slides is that the rear loops of the paper, which are already partly dried, be sus pended more closely together than the front wet loops.

The gearing f c of the chains and the slides should be so proportioned that the slides complete two or more strokes between the de= livery of one stick and the delivery of the next stick. Thus in the drawings the slides will reciprocate four times for each complete rotation of the chains, so that while two sticks are delivered the slides will make four strokes. The consequence of this arrangement is that the slides will not advance a loop of paper for the whole Width of such loop during each stroke, but only for, say, half the width, so that the loops will advance in small stages and be more thoroughly dried while traveling.

The operation is as follows: A stick I) will be deposited upon ends of rails d, and the first loop of paper A delivered from roller A will be laid around it. The stick Will now be engaged by pawl 1 and advanced for one-half the space desired. During the next stroke pawl 1 will run idle and the stick will be engaged by pawl 2 and advanced for another half-space. At the completion of this second stroke anew stick will be delivered to pawl 1, so that pawls 1 3 5, &c., will alternate in being active and idle with pawls 2 4t 6, &c. The consequence is that while the stroke of the machine is small the paper will be moved along rapidly in small stages to be effectively sticks, and means for driving the chains and dried. slides at different speeds, so that alternate 10 hat I claim ispawls will run alternately idle, substantially A paper-drying machine composed ofa pair as specified. 5 of inclined driving-chains having noses, a JOHN A.
