MEANS FOR ATTACHING VALVE-STRIPS TO BAGS.
Specification of Letters Patent. Application filed February 5, 1909. Serial No.
Patented Mar. 22, 1910. 476,292.
To all whom it may concern:
Be it known that I, FRANK E. BEAM, a citizen of the United States, and aresident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Nleans for Attaching Valve-Strips to Bags; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.
My invention relates to means for use in machines for securing valve extension strips to bags during the manufacture thereof, said strips being of paper, cloth or other material suitable for such purpose and preferably of a more sensitive nature than the material from which the bags are made.
The object of my invention is the provision in combination with a feed drum of simple and efficient mechanism for intermittently drawing predetermined lengths of material from a roll or other source of supply located exteriorly of the drum, applying aste thereto, severing such lengths and finally securing them to bags in proper position to provide valve-extension strips therefor.
The operation, construction and arrangement of the parts of the invention are fully described in the following specification, and while in its broader aspect it may be embodied in different forms of mechanism and its parts differently arranged and constructed a preferred form thereof is illustrated in the accompanying drawings, in which,-
Figure 1 is a rear elevation of a mechanism embodying my invention with portions of the frame and feed drums broken away and the drum turned into position for the gripping-finger to grip the strip of material. Fig. 2 is a vertical section on the line m w 111 Fig. l, with portions of the parts broken away and the drum in the position at which the gripping-finger moves to release the strip, and Fig. 3 is a side elevation of a por chine with which any valve-strip tion of the upper drum with the gripping mechanism associated therewith.
Referring to the drawings, 1 designates a portion of one side of the frame of a maattaching mechanism is associated, 2 a shaft which has journaled in a suitable bear- 1 mg in the drum 3.
Rising from a frame 5, which is shown as I being disposed above the drum 3 and secured at one side to the frame 1 is an arm 6, which has a spindle 7 projecting horizontally from its free end. A roll of paper, cloth or other material 8 suitable for the valve strips is intended to be carried by the spindle 7 and has its free end passed under and idler rolls 9 and 10, respectively, which are carried in horizontally offset relation by spindles 11, 11 projecting from the lower portion of the arm 6, and thence passes down between a set of small feed rolls 12, 12,
I which are disposed in contiguous position to bearing-blocks 15, (see Fig. 2) each of which is acted on by a spring 16.
One of the shafts 13 is prolonged and has an end journaled in the vertically disposed part 5 of the frame 5 and has rotation communicated thereto from the shaft 2 through a train of gears 17, the idlers of which are shown as being carried by spindles projecting from the frame part 5. The size of the driveroll 12 and its speed of rotation are so proportioned that a predetermined length 0 material 8 is fed out at each revolution of the drum 3.
Paste, glue or the like is applied in proper position to one side of the material or tape 8 as it is drawn from its roll due to a narrow paste roll 18 bearing against the ma terial in opposition to the roll 9 as it passes thereunder. This paste roll is carried by a forked arm 19, which projects from a stand ard 20 rising from the frame part 5, and has its lower portion projecting down into a paste-pan 21 from which it receives its paste supply. The feed-roll 12 with which the pasted side of the material has contact is peripherally grooved, as at 12, to prevent the pasted portion of the material from having contact therewith, thus leaving the paste intact on the material until a severed strip has been pressed to a bag which is fed between the two drums 3, 4.
over a pair of Projecting through a transverse opening in the shaft 2 at the end of the drum 5) contiguous to the frame 1 is a rod or bar 22, which attaches at one end to a rockerarm projecting from a shaft 24:, that is mounted within the drum in suitable bearings 25 secured to the inner side of the drum rim or shell. The shaft 24 carries a gripping-finger 26 the outer end of which is adapted-to move into a contiguous opening 27 in the drum rim and to cooperate with the rear beveled end edge of such opening to grip the free end of the material strip or tape, as hereinafter described. The rod or bar 22 carries a roll 28 intermediate the rocker-arm 23 and shaft 2, which roll travels around the periphery of a stationary cam 29.
The cam 29 loosely encircles the shaft 2 and is prevented from turning therewith by being attached to a bracket arm 30 projecting from the frame 1. The roll 28 is yieldingly held to the periphery of the cam 29 by means of a coiled compression spring 31, which encircles the rod or bar 22 at the 0pposite side of the shaft 2 to the roll 28 and has its ends thrust against said shaft and a collar 32 on the rod or bar.
The formation of the cam 29 is such that the gripping-finger 26 is rocked to grip the feeding enl of the material 8 as the rear end of the opening 27 in the drum 3 passes the end of such material, and is rocked to release the material as its outer end passes the point of bite of the companion drums 3's, thus leaving the material free to adhere to a bag, which is passing between the drums simultaneous therewith. When the finger 26 grips the end of the material 8 a sudden jerk is imparted to the material, due to the drum moving at a greater speed than the feed of the material, thus causing the fed end of the material to be severed from the roll strip at its point of contact with the serrated edge of a knife 33, which knife is disposed beneath the grooved roll 12.
The operation of the mechanism is as follows .-At each revolution of the drum 3 a predetermined length of material 8 is fed down onto the upper surface of the drum and car "ied by the frictional contact of the drum therewith in the direction of rotation of such drum, and a corresponding length has paste applied in proper position to one surface thereof as it is drawn between the paste-roll 18 and the roll 9. As the end of the opening 27 in the drum rim passes the free end. of the material strip the roll carried by the rod or bar 22 suddenly drops from the neutral zone a to the neutral zone 7) of the cam 29, thus efiecting a quick movement of the finger 26 to grip the end of the material against the beveled rear edge of the opening 27. On the continued movement of the drum the fed length of material is severed from the roll strip at its point of contact with the knife, due to the more rapid movement of the drum than the feeding o the material, and is carried around by the drum and pressed thereby in proper position on a bag to form a valve extension strip thereon. As the outer end of the gripping finger passes the point of bite of the drums 3 4 the roll 28 on the rod or bar 22 moves into contact with the cam portion 0 of the cam 29 and is suddenly forced outwardly from the zone 6 to the zone a of the cam,
thus rocking the finger 26 to release the forward edge of the severed material strip to permit suci strip to remain attached to the bag. It is, of course, apparent that the feeding of the bags to the drum s4. is so timed that the valve-strips are placed in proper position thereon.
I wish it to be understood that my invention is not limited to any specific construction or arrangement of the parts exceptin so far as such limitations are specified in the claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is-
