To all whom it may concern: v and without reversing the bottle.

The bottle bodies are fed such as are used for contaming milk. The forward in series, step by step, and located 5 bodies of such bottles are usually cylindrical precisely in position, and the action of the paper tubes having paper tops and bottoms plungers and dies is nearly simultafieous, which are both adapted to fit closely within or, in other words, while a bottom is being the ends, respectively, of the tube. The botout and inserted in one body, a top is being tom is permanently fixed in the tube, but in pushed downward in another, atop is being 0 certain forms the top' is removably placed out and inserted in a third, and a small disk in position.

This cutting, forming and inserting device has no novelty herein claimed, in construction or action. The plunger Ein rising-leaves the flanged disk in the upper part of the bottle body and by means of a crank plate i on the crank shaft, a pitman G loose crank G", and common pawl and ratchet devices G, the belt advanced one step, that step being an exact fraction of the distance between the axes of the two 'plungers' E, and is thus brought to rest'in registry with a plunger H having a long hollow body provided with a head H. to the upper side of which is hinged a plunger rod ll pivoted above to an arm H the opposite end of which is pivotally attached to a portio rA of the frame. This arm is swung back and forth by means of a rod H", of adjustable lei'igth, pivot-ally coir ne'cting itWvith a projection' II from the plunger rod of the plunger E. The plunger H is closely'encircled by a loose sleeve H which itself slides in a sleeve-like bearing H on the frame and is provided at its lower end with an internally conical annular head H" to receive the upper end of the bottle body and hold the same in exact position.

The sleeve II frictionally engages the plnnger' and the friction is adjusted by means of a sleeve-encircling band H and a screw Il The tension being properly adjusted the sleeve moves with the plunger so long no special resistance is offered, but the downward movement is arrested by the bottle itself,-after which the continued descent of the plunger forces the flanged top down fully to the lower end of the bottle body :(see Fig. On the return of the plunger, the sleeve accompanies it until the head H meetsthe bearing If, after which the plunger continues to ascend alone, 4 this being necessary, because otherwiscsome means must be employed to hold the plunger atr'est while other functions are performed by other parts. If no means were provided to prevent, the sleeve would descend with the first downward movement of the plunger and would reach its lowest point sooner than 4 is desirable. For this reason a spring I actuated. stop I is provided. This stop, moving in a way in the sleeve bearing H passes ward until the incline lies in the wall of the sleeve, and as the 'latter is frictionally urged downward it in turn presses upon the incline, forcing the stop farther outward out of the sleeves path, and descends with the further movement of the plunger until it meets the bottle body. \Vhen the plungers again rise, the ising stroke of the crank feeds the belt forward another step, and the entire operation described is repeated.

After a certain number of steps in the ad- Vance of the belt, the first bottle in the lower end of which a top was inserted comes to rest in exact registry with the second cut-ting die E and plunger E which act, precisely like the corresponding parts already described, cutting a disk from a second stock strip fed by rollers F as before, forming it,.

and inserting it as a flanged bottom in the upper end of the inverted bottle, after which the advance of the belt discharges the bottle ready for parafiining. As shown, the upper fold of the belt is supported below each set of cutting and inserting devices by a removable block resting upon the bed of the frame and of a height equal to the interior height of the bottle. In case, it be desired to produce bottles of double capacity, for example, to holda quart instead of a pint, these blocks are removed, allowing the belt to rest upon the bed, and the driving wheel is turned backward, its pawl being lifted, to transfer the stock of the belt to the lower fold, and the upper end of the rod H is moved nearer the pivot of the arm H so that the throw of the plunger H may be correspondingly lengthened. In this case the bottle bodies fed by the belt are of course correspondingly lengthened.

hat I claim is:

1. In a machine of the class described, the combination with means for feeding bottle bodies to position, of means for insertin closures in the upper ends of said bodies, an automatic means for forcing the inserted closures to the lower ends of the bodies, respectively.

2. The combination with means for advancing inverted bottle bodies step by step,

closure in the body to the opposite end thereof, anda device carried'by the plunger and s seaaeo adapted to hold the end of the bottle in accurate adjustment while the plunger enters the same.

4. Tihe combination with means for supsition for engaging and adjusting the end of the body prior to the entry of the plunger 7 therein.

5. The combination with means-for supporting a bottle body havingta to in its bot tom end, of a plunger arranged or pushing said top to the opposite end of the body, a sleeve lnolosing and frictionally engaging the plunger and havin an end adapted for adjusting the bottle b0 y as it is frictionally advancing with the plunger, and means for arresting the retreating movement of the sleeve before the retreating movement of the .7 plunger is completed. I

6. The combination with an endless belt arran ed to advance a series of inverted bot tie ies stepby step, of meansfor insert ing perf'orated tops in the upper end of each i body during one of its periods of rest, means for pushing the inserted tops in suceession to the opposite ends of the body during subsequent periods of rest, and means for inserting bottoms in the bodies in succession during later periods of rest.

' 7. The combination'with an endless belt adapted to advance a series of bottle bodies step by step, of means for supporting the upper fold of the belt at difierent heights according to the heights of bodies to be used, means for inserting bottle tops in said bodies in succession during successive periods of rest, a plunger arranged to advance each top to thelopposite end of its body during a period of rest subsequent to its insertion, and. means for varyingthe throw of the plunger for bodies of different heights.

In testimony whereof I afiix my signature in presence 0 two Witnesses.
