PAPER-LIFTING MECHANISM.

skilled in the art to which the invention appertains to make and use the same.
ur improvements relate to what are known as suction-fingers in paper-manipulatingmechanism, and are designed to render the same more certain and positive in operation. As ordinarily constructed and used the suction-fingers are each formed with a single.
concavity on the under side. As a result, if there is any decided unevenness or irregularity of surface in the paper to be lifted and transferred or if the paper becomes bent or crumpled the suction exerted through the finger isinefifectnal, since airleaks in between the paper and the edges of the suction-finger and the requisite partial vacuum cannot be attained therein. We obviate this difficulty by forming the suction-finger with a plurality of openings on its under side, opening into a common vacuum-chamber, and by providing each opening with a valve which acts automatically, if there is a leak of air into such opening, to close the passage into the main vacuum-chamber, and thereby allow the edges of the remaining openings to'maintain their hold on the paper.
In the accompanying drawings, Figure 1 is a longitudinal vertical section of our improved form of suction-finger; Fig. 2, a transverse section upon plane of line 2 2, Fig. 1; Fig. 3, aview of the under side of the suction-finger.
The suction-finger F, in general form and arrangement, is essentially the same as those heretofore in use, being connected, by flexible tubing attached to its shank f, with suitable vacuum apparatus and being mounted and operating in the usual and well-known manner. The openin g f in the shank f communicates with the longitudinal vacuumchamberf which, instead of having a single extended opening in the underside of the finger-piece, is formed with a series of airducts a a, which open into valve-chambers, formed in turn with openings 61 d, the lips of which bear upon the paper. The air-valves c 0 may be of any desired form. In the construction shown in the drawings they consist of balls 0- c, slightly larger in diameter than the ducts a a, and suctionopenings d 01. Thus when the paper to the surface of which the suction-finger is applied is smooth and even the suction exerted through the openings dddraws the adjoining paper against the lip-openings d d and holds it there as long as the partial vacuum is maintained within the chamberf In case, however, of a rough or uneven surface under or adjoining one of the openings (1 air will rush into that particular valve-chamber and force its valve 0 against the air-duct 0,, thereby preserving the partial vacuum in the chamber f and maintaining the hold of the'other openings d d upon the paper.
'Any desired or suitable number of openings and valves may be provided for the vacuum -finger. The greater the number employed the greater will be the certainty and delicacy of operation of the finger, which is practically rendered positive in action byour invention.
What we claim as our invention, and desire to secure by Letters Patent, is-
1. A device for lifting and transferring sheets of paper formed with a vacuum-chamber having a plurality of openings in which are situated loosely-mounted automatic airvalves each confined wholly within itslopening, for the purpose set forth.
2. Asuction-finger for lifting and transferring sheets of paper formed with a vacuum-chamber having a plurality of air ducts and chambers in each of which is situated a loosely-mounted automatic valve confined wholly within its chamber, for the purpose set forth.
3. In a suction-finger F, the combination of the common vacuum-chamber f the series of air-ducts a, a, the ball-valves c, c, and
the suction-ports d, (:2, arranged and operating I ball-valves loosely mounted in such charn- 1o substantiallyin the manner and for the purbers of greater diameter than said ducts and pose described. suction-openings, and adapted to serve sub- 4.
