AUTOMATIC SPRING-TENSION FEED.
No. eze-,50s
I attain this object the mechanism illustrated in the accompanying drawings, in which I `1gure l 1s a perspective view of a section ci' a printing press showing my automatic4 'feed device 1n position; and Flg. 21s a per.
spective viewA of a complete arm and fork showing means on feed roller.
In the drawings like letters. of reference indicate Correspending'partsv in each figure. I provide a series of arms secured by n'ieans of set screws to a transverse shaft and hinged at the ends of these arms are a 'series of forks designed .to keep the feed rollers in close contact with the calender roller over which the paper passes. It is necessary that the paper be held perfectly tantas *other wi it would buckle and tear.v
My invention keeps an automatically regulated strain on the paper and, eliminates the expensive and unreliable larrangement .of steel shafts and leather beltsnow in general use.
Referring to the drawings, A is the main frame of the printing press, B is the cal' ouder roller over which the paperO passes.
Specification of Letters Patent.'
Application filed December 22, 1908. Serial No. 468,863.
of securing spring tension Patented June 29, 1909.
D is a transverse steel shaft'supportiug the arm E which is secured by means of a set screw a.
F is afork hinged to the arm E at 7) and retaining the roller G in position.
H is a tension spring secured at oneA end to an' extending lug` c on the fork F and at the other end to a tension screw d. The tension screw d is secured by the depending lug* c Von the armrE and is provided with a thumb v nut- It will be readily seen that as the thumb' nut f is screwed up, the tension on the spring isincreased. This permits va quick adjustment and assures aconstant pressure of the feed rollers G on the calender roller B.
` What I claim as new and desire to secure by Letters Patent of the United States, is
1. In an automatic spring tension feed,
the combination of a shaft, a series of arms adjustably mounted on said shaft, hinged rollers mounted on saidarms, springs formlng part of the tension 'feed and movable with said rolls durmg adjjust-ment on said shaft7 and means for varying the tension of 'the springs to change the pressure'of the rollers.
2. In an automatic spring tension feed, the Acombination of a shaft, a series of supporting arms mounted thereon, means for adjusting the arms on the shaft,.4 hinged forks on said arms, rollers carried on said forks, springs lfor the hinged forks, and means for varying the tension 0f saidvsprmgs to change the kpressure of the rollers.
In witness whereof, I have hereunto ser. my hand this 12th day of March, 1909.
