and furthermore this is fully described in 1 my Patent No. 1,021,049.
-To the standards 3 and 6 cams 29 and 30 are secured which, in the manner described in the two patents previously mentioned serve for swinging the clamping levers ll downward when the bars of the lowest chains have reached the highest points on the wheels 4 and for swinging these levers upward when the bars on the lowest chains begin to travel downward from the highest points of the wheels 1. The bars on the two chains are so arranged that when one of the bars 8 on the lowest chains arrives in the highest position upon the sprocket wheels that is, directly above the shaft 5, the corresponding bar 20 on the upper chains-19 will rest directly above said high- =est bar 8, that is directly above the paper upon said bar 8. When these two bars are so positioned, one directly above the other,
the corresponding clamping levers 11 are thrown into the position shown on the top bar 8, in Fig. 2, and hold the corresponding bar 20, of the upper chains, firmly upon the paper resting upon the corresponding bar 8 of the ldwer chains and as these clamping members under spring pressure they are held in place; in relation to the bars 8 of the lowest chains and as the chains move at the same speeds the said bars 8 of the lowest chains andhbars 20 of the upper chains, while clamped together, can move from right to left, Fig. 1, until the corresponding clamping levers 11 are disengaged by the cam 29 and so on. The paper is thus not clamped only at each side edgcof the strips or hands of paper passing through the machine but is always clamped through out its entire width by a bar 20 of the upper set of chains being clamped to a corresponding bar 8 of the lower set of chains. This prevents buckling, crinkling and folding of the paper transversely and also prevents undue transverse strain on the paper and insures a uniform, regular and reliable feed. Having described my invention what I claim as new and desire to secure by Letters Patent is Y 1. In a paper feed mechanism for paper perforating machines, the combination with two pairs of endless chains, sprocket wheels for each pair of chains and bars uniting the chains of each pair of chains, one pair of chains and its bars being superimposed above the other pair of chains and its bars,
the chains of the lowest bar being suhstanthem upon the upper bars, substantially as set forth.
2. In a paper feed mechanism for perforating machines, the combination with two pairs of endless chains, bars uniting the endless chains of each pair, separate sprocket wheels for each pair of chains, onepair of chains beingsuperimposed above the other, clamping means on the ends of the bars of one pair of sprocket chains, for clamping the bars on the other pair of sprocketchains, and mcansfor alternately applying and disengaging the clamping means, and independent means for each pair of chains for driving both pairs of chains at the same speed, substantially as set forth.
3. In a paper feed mechanism for paper perforating machines, the combination with a pair of endless chains, sprocket Wheels over which the chains are passed, bars uniting the chains and secured between the chains, a series of bars located parallel to the bars on said chains and located above the same, chains connected with said upper bars, between the ends of these bars, locking means for locking the bars of the upper pair of chains on the bars of the lower pair of chains and means for alternately applying and disengaging these locking devices, substantially as set forth.
Signedat New York city, in the county. of New York and State of New York this 24th day of September A. D. 1912.
