To all whom it may concern.'

Be it known that l, CHARLES FRANCIS JENKINS, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Coating Paper Receptacles, of which the following is a specification, reference being had therein to the accompanying drawing.

For certain uses it is found desirable to coat the ends of paper bottles and the like after they are completed and to provide means for doing this rapidly, coating all to a predetermined distance from the end, is the general object of this invention. rlhis is done by providing a shallow trough having at each end inclines or ways extending from its bottom to its margin, adding devices for keeping the liquid coating material at a constant level in the trough, and further adding an endless carrier chain or the like between the cross bars of which bottles are inserted, to be dragged along the bottom of the trough while erect.

In the accompanying drawings, Figure l is a plan view of the novel partsof the apparatus. Fig. 2 is a side elevation, partly in section, of the same devices. Fig. 3 is an end elevation of the structure.

In these figures, A represents a suitable frame supporting a broad shallow trough B,of any desired length, around the front side of which passes an endless chain belt C carried by sprocket wheels C and driven by a shaft C2. The chain may be composed of two parallel chains C, at a distance from each other somewhat greater than the diameter of the bottles to be treated, and connected by cross bars C4 shown at approximately the same distance apart as the chains. That portion of the bottom .of the trough which lies between the folds of the belt has false bottom strips B forming upwardly inclined ways. As shown, the strips pass over the ends of the trough and preferably projectat B2 to some distance beyond the same. If bottles D be placed on end between the crossbars so that they rest upon the part B2 they will be dragged along the ways and bottom always descending by gravity to follow the waysv and bottom, and will finally be passed from the trough at the opposite end. When paran is used as the coating material, the trough is heated by as many burners E as may be desired. To insure a desired constant level of the material in the trough, I provide an upwardly closed tank F having a downwardly open projecting portion F provided with lateral openings F2, and further provided, 1n this instance, with a supporting projection F3 which rests upon the frame, while the open portion F rests freely upon the bottom of the trough. The tank being inverted, solid pieces of paraiiin may be dropped into the open portion F', and a suitable amount may be placed in the trough also. The tank is then placed in the trough as shown. Heat being applied by the burners the whole will be liquefied. The apertures are at such distance above the bottom of the trough that fwhen the liquid is at the desired height in the trough they are barely covered. As no air can now enter the closed tank, no liquid will ow therefrom into the trough, but as soon as paralin is used from the trough, lowering the level, air enters through the aperture and liquid descends into the trough unt-il the apertures are again covered, and thus the liquid is automatically kept at the desired level and all the bottles are coated to the desired height. Obviously, this distance is governed by the dista-nce of the apertures from the bottom of the pan; and this distance may be readily varied, of course, to suit the requirements.

. What l claim is:

l. In apparatus of the class described, the combination with a trough adapted to contain a coating liquid, of a rack-like belt arranged to travel over the trough at a fraction of a `reeeptacles height from the bottom of the trough and receive in its openings upright paper receptacles resting on the bottom of the trough, and means for driving the belt whereby the lower end only of receptacles may be heavily coated.

2. An open trough adapted to contain coating liquid and having at opposite ends inclines adapted to lower to the bottom of the trough articles forced along the one ineline and to raise them from the bottom as they are forced in the same direction along the other incline, ranged to pass over both inclines Iand to engage a series of upright receptacles to be of a traveling belt arcoated and advance them while leaving them free to rise and fall following the bottom and incline.

3. The combination with a coating trough have at each end near one side smooth inclined ways leading from its bottom to its top, of a rack-like endless belt assing around the trough in the plane of said ways and adapted to have a series of bottles set loosely in its meshes, to rest upon the ways by gravity and be moved laterally by the belt regardless of the belts engagement.

4. The combination with a shallow coating trough having at each end near one side smooth inclined ways along which bottles may'slde from its top to its bottom and from its bottom to its top, of an endless belt having openings to loosely hold laterally bottles resting upon the bottom of the 'trough and said ways and passing around the trough in the plane of the Ways, and an upwardly closed tank having a broad open mouth in the trough and provided with a lateral opening at the height desired for the coating. liquid in the trough.

In testimony whereof I aflix my signature in presence of two witnesses.

CHARLES FRANCIS JENKINS.
