Jan, 21, 1930. s. SOKOLOW AUTOMATIC DRY CELL MAKING MACHINERY Filed April 2, 1927 SAMUEL SOKOLOW M a t l m 01mm Patented Jan. 21, 1930 i UNITED STATES 'PA' I'ENToOFFICE SAMUEL SOKOIIOW, OF NEW YORK, N. Y., ASSIGNOR '10 ABINGDON ENGINEERING 60-, INC., OF NEW YORK, N. Y., A CORPORATION 01 NEW YORK AUTOMATIC DRY-GELL-MAKING MACHINERY Application filed April 2, 1927. Serial 30. 180,432.
In the manufacture of dry-cells for flash lights and the like a bobbin, as it may be called, is first formed consisting of a cylindrical portion of a matrix composition having a rod-like carbon electrode as a core protruding from one end. This -bobbin is placed within a cup-shaped zinc electrode, the electrolyte poured in, the mouth of thecup sealed about the electrode and a brass contact cap placed over the protruding end of the core. It is customary to wrap the bobbin with a fabric before its insertion in the cup in order that no particles of the matrix be broken off in the process of insertion which would bridge the'cup and bobbin and short-circuit the cell. The manufacture of the bobbin has heretofore been performed principall by hand.
In a copending application y the present applicant filed August 13, 1926, Serial Number129,098, a machine for the automatic performance of many of theforegoing steps is disclosed. In one embodiment this machine involves a continuous bobbin conveyor along which are disposed, for instance, a tamping device for curling one end ,of the fabric wrapper and the cord winding about one another to secure the end of the cord, folding devices for the opposite end ofthe fabric wrapper and smoothing means for the corners of the folded wrapper to merge them into thebobbin pauses in its progress through the machine. Preferably, a container of molten par- .aflin is disposed at'that station wherein the projecting corners of the wrapping are ironed down and merged intothe cylindrical surface of the bobbin, and a brush or paraflin apithin the parafiin container into contact with the bobbin by a convenient moving. part of the machine, say the tamping mechanism.
This and other objects of the invention and the means for their attainment will be more apparent fromthe followin detailed description taken in connection wifii the accompanying drawings illustrating a preferred embodiment thereof, in which:
"Figure 1 is a view in transverse vertical section showing a fragmentary part of the bobbin wrapping machine provided with the adhesive-applying device according to this invention.
Figure 2 is a plan view of the construction shown in Figure 1.
The bobbin electrode, as it may be called, com rising a carbon rod electrode 5 protruding rom one end of a cylindrical matrix bobthe station illustrated in Figure 1, the wrap-- ping has been already tied with the cord, the
end of the wrapping folded over the end of the bobbin and secured by adhesive, and the opposite end of the fabric tamped by the tamping device 11 about the rod electrode 5. At the station illustrated, a die 10 is provided which takes the form of a roller constantly driven and provided with a friction surface which engages the peripheral surface of the bobbin and causes its rotation within the carrier 9; and the annular cam surface 12 irons down the protruding corners of the wrapper and merges them with the cylindrical surface of the bobbin.
This rotation of the bobbin by the roller 10 is availed of in the step of applying the paraflin to the carbon "electrode which forms the subject matter of this invention. Mounted upon the frame 13 on the opposite side of the conveyor 8 from the iromng means 10, 12 is a tank 14 suitably heated and adapted to contain paraflin in a molten condition. plicator is provided movable from a POlIliZ and is provided at its extremity with a brush 17 or other paraflin applicator, so that rotation of the rock shaft 19 causes the brush 17 on the arm 16 to be raised, at suitable intervals of time, out of the araflin bath to appl the paraflin to the en of the bobbin wit which it contacts, the arm 16 being of suflicient length for this purpose.
The operating mechanism for the arm 16 is conveniently illustrated in Figure 2. The end of the shaft 19 opposite to the arm 16 carries rigidly therewith an arm 21 which is suitably connected, as by the link 22, with the lever 23 which operates the tamping mechanism 11 from the cam 25. Thus every time that the tamping mechanism 11 is operated at the preceding station upon a following bobbin, the bobbin electrode at the succeeding station is treated to an application of paraflin.
Various modifications may be made in the form taken by the mechanism as a whole as well as its application and. no limitation is intended by the phraseology of the foregoing specification or illustrations in the accompanying drawings except as set forth in the appended claims.
What I claim is:
1. In a machine for wrapping a bobbin electrode having a protruding core, in combination, a horizontal endless conveyor having a step-by-step movement thereby holding a bobbin thereon momentarily stationary at a predetermined point, a roller disposed above the conveyor to contact with the bobbin carried thereby and rotate the same on the conveyor while momentarily stationary,
a tank for paraflin, a pivoted lever, a paraflin applicator carried at the end of the lever, and means to swing the lever end into the tank and into contact with the core.
2. In a machine for wrapping a bobbin electrode having a protruding core in combination, a horizontal endless conveyor for the bobbin having a step-by-step movement, thereby holding the bobbin thereon momentarily stationary at a predetermined point, a means to rotate a bobbin on the conveyor while momentarily stationar a tank for molten paraflin adjacent the obbin and on the opposite side of the conveyor from the bobbin rotating means, a rock shaft journalled on the tank, an arm carried with the shaft and adapted to dip its end into the paraflin, a paraflin applicator at said arm end,
a second arm carried with the rock shaft and a link pivoted at one end to the second arm and at its other end to an actuating means.
In testimony whereof I aiiix m signature.
SAMUEL SO OLOW.
