PAPER MACHINE. APPLICAUON 'FILED 1uLY|a,|921.
Patented June 27 1922.
OFFICE.
FRANK O. SCOTT, OF MITTINEAGUE, MASSACHUSETTS, ASSIGNOR TO SOUTHWORTH COMPANY, OF MITTINEAGUE, MASSACHUSETTS, A CORPORATION 0F MASSA- CHUSETTS.
PAPER MACHINE.
Application led July 18, 1921. Serial No. 485,524..
To all fte/tom t may concern.'
Be it known that I, FRANK O. SCOTT, a citizen of the United States, and a resident oi Mittineague, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Paper Machines, of which the following is a specilication.
This invention relates to paper machines, and particularly to a lay-boy construction whereby sheets cut from a traveling web of l paper may be properly piled in stacks.
1t is an object oi' the invention to produce an apparatus ot the character described which is simple mechanically, and efficient.
Tn the drawings which present an illustrated embodiment of the invention,
Figure 1 is an elevation of a lay-boy device adapted to be placed at the delivery end ot the paper machine,
Figure 2 is a cross-sectional elevation of a part thereof, and
Figure 3 is an enlarged detailed view of one et the links or' the chain.
This device comprises a. pair of frames 1 between and under which and transversely oi' the direction ot delivery ot the paper is a truck 2 having a table 3 upon which the paper '-1 is to be piled. Suitable mechanism not herein shown, and not forming a part of the invention, is provided tor raising and lowering the table as the stacking or piling proceeds. Arranged across the two trames 1 are a plurality ot lay-boy rolls 5, these rolls havingl square portions G at one end, and gears i at the other. Mounted on the Yframes is a track 8 and al rack 9, one on one iframe, andthe other on the opposite trame. The lay-boy rolls travel around the frames in the direction @it the arrow in Figure 1. 1When nim/'ing horizontally along the top of the trames, they move without rotation until the rack 9 engages the gears 7, at which time the rolls revolve and lay the paper smoothly on the pile.
V ery considerable diliiculty has been encountered in maintaining` a proper alignment and synchrony in the operation of the lay-boy rolls. These rolls are usually of considerable length rapidly rotated, and or'- dinarily rotated Jfrom one end only.
Specification of Letters Patent.
Patented J une 27,1922.
I have provided means whereby the two ends of each roll may be positively'ckept in exact alignment across the machine, and the difculties heretofore encountered obviated. This result I obtained by employing a pair of strong chains 10 stretched tightly about the rollers 11 and the sprockets 12 on each frame. The two sprockets 12 are mounted on a common shaft and driven by any suitable means. y
The engagement or the chains with the two sprockets 12 is positive, exact, and does not vary through long periods of use.
i In order to connect the chain with the layboy rolls secure, as by brazing or welding, journals 13 to links 111F of the chain. These journals are arranged on exactly corresponding links of the two chains. The lay-boy rolls 5 are mounted in the journals 13. By this construction, the parts being once in alignment, the troublesome diiiculties of the prior art practice which occur through the lack of exact synchrony between the two ends of the lay-boy rolls are obviated, and a construction is provided which maintains the exactness of its operation through long periods of use without adjustment.
l claim as my invention:
1. 1u a lay-boy device for paper machines, a frame, plurality of lay-boy rollstracks in the frame for the end of the rolls, a rack as sociated with one track, a gear on each of the rolls cooperating with the track, a pair of chains connecting the corresponding ends of the lay-boy rolls, and pulleys for guiding the chains.
2. In apparatus ot the class described, and in combination a pair of frame members, a pair of chains each associated with a frame member, rollers supported in the frame and guiding the chains, a shaft sprocket for driving the chains, a series of journals mounted on links of the chain, and in alignment in pairs across the trames, rolls journalled in said journals, a rack on one frame, a gear on each roll, engageable with the rack.
In witness whereof, 1 hereunto subscribe my name this 8th day of July, A. D., 1921.
FRANK O. SCOTT.
