WRAPPING-MACHINE.

Specification of Letters Patent.

Patented May 18, 1920.

Application filed December 10. 1918. Serial No. 266,114.

To all whom it may concern:

Be it known that I, WVILLIAM B. MUNN, a citizen of the United States of America, residing at Memphis, in the county of Shelby and State of Tennessee, have invented'certain new and useful Improvements in VVrapping-Machines, of which the following is a specification.

The present invention relates to an improved wrapping machine, designed particu larly for use in wrapping or packaging collars and cuffs in the laundry, but adaptable of course for use in other connections and for other purposes, as will readily be understood. For convenience of description, however, the invention in the present instance will be referred to as a collar and cuff packaging or wrapping machine, preferably operated manually, and designed to build up a uniformly cylindrical bundle or package of laundried cuffs or collars, having the ends of the paper wrapper tucked in at both ends of the package, and presenting a neat and attractive bundle as to its shape and appeara-nce.

The invention consists essentially in the utilization of a fixed receptacle having a movable bottom upon which the collars to be wrapped are placed, and in certain novel combinations and arrangements of parts whereby the size of the paper sheet required is gaged, and particularly in combining with the movablebottom of the receptacle, means for imparting friction whereby the bottom is free to be pulled up, but must be pushed downwardly, all as will hereinafter appear more specifically' In the accompanying drawings one complete example of the physical embodiment of the invention is illustrated, constructed and arranged according to the best mode so far devised for the practical application of the principles of the invention.

In the drawings 2 Y Figure 1 is a perspective view showing the machine complete, and illustrating also in connection therewitha paper cutter and a tagging or labeling device for the completed showing details of constructionof the rer'ocablerplunge rlo 'o'r stern.

ceptacle, its movable bottom, and the lifting and lowering means for the bottom.

Fig. 5 is a sectional View taken at line 55 of Fig. 3.

Fig. 6 is an edge view showing the friction device for retarding the downward movement of the plunger rod that supports the movable bottom or plunger head. Fig. i is a side view, as seen from the right in Fig. 8 is a vertical sectional view of" the friction device or retarder.

1 Fig. 9 is a top view of the device as in In the preferred embodiment of the invention as illustrated in the drawings, the machine is adapted for manual operation and is depicted as supported upon a table 1 in combination with the frame 2 which supports the paper roll 3 from which the wrapping paper for the bundle is to be taken.

The paper from the roll passes over guide rolls 3 and is out by a reciprocable cutter 4 slidable on the guide rod 5 and provided with a rotary cutting knife 6 that travels in the groove 7 of the ifixed bar 8 supported in the frame 2. The sheet of wrapping paper is drawn from the 'roll 3, by hand, and the required length of paper is cut from the roll by manual manipulation of the slidable cutter, and then this sheet of out paper is wrapped about the receptacle 9 in which the collars and cuffs are piled or stored preliminary to wrapping them.

The receptacle is preferably of metal, cylindrical in shape to conform to the collars, and of suitable dimensions to receive the collars in their normal condition, as indicated by dotted lines in Fig. 2, wherein the paper wrapper is also indicated by dotted lines.

The receptacle 9 hasan open top to receive the collars and cuffs, but is fashioned with a closed bottom 10, except for the central orifice 11 therein, and by means of the flange 12, exterior of the receptacle and Within the receptacle the vertically rec'p 14, which forms the movable bottom of the receptacle, are operable, the bottom fitting neatly within the interior of the cylindrical receptacle, and the stem 13 passing freely,

.but not too loosely through the opening 11 in the bottom plate 10 of the receptacle. The movement of the stem and bottom is guided and rendered stable by the utilization of three vertical guide rods 15 that are connected at their lower ends beneath the table top 1, by the spider frame 16, and a threaded extension bar 17 of the stem also is fixed at the center of the spider, clamping nuts 18 being provided to make a firm joint. These three rods and the spider form a guide frame that is completed by the upper flanged ring 19 which surrounds the receptacle above the table and to which the rods are rigidly fastened as seen in Fig. 3. From this description it will readily be seen that the stem, spider, guide rods, and ring 19 form a movable guide frame for the bottom 14 of the receptacle, and as the rods pass through small openings 20 in the bottom plate 10 of the receptacle the stability of the frame is enhanced so that these parts may be lifted or depressed without wabbling. Usually the movable bottom is manipulated manually by grasping the ring 19 in the hand, and thus the bottom may be freely lifted through the co-action of the frame, but preferably the lowering movement of the bottom is to be retarded, and as a matter of fact, the movement is stopped, and the movable bottom held in position by means of a friction device co-acting with the stem, so that the bottom may not be lowered without power being applied, preferably by hand on the ring 19, as will be described.

In connection with the movable ring 19, a paper or wrapper retaining device is utilized, which includes a pair of parallel rollers 21 movable in a vertical plane with the ring 19, and supported from the ring by an arm 22 pivoted at 23 in the ears 24 on the ring and a spring 25, between lugs of the arm and the ring, holds the rollers 21 against the paper that is wrapped about the receptacle. Thus the paper sheet is cut from the roll and wrapped about the receptacle, the size of the sheet being determined by the eye of the operator. It will be noted that, in their fixed relation, the bottom 14 is above the ring 19, so that when the bottom edge of the paper sheet is brought down to the ring 19 and the sheet wrapped about the receptacle, the upper edge of the sheet projects above the upper edge of the receptacle, and the lower edge of the sheet is below the bottom of the package that is to be formed on the movable bottom, thus providing upper and lower edges of the wrapper that may be tucked in when the bundle is complete.

The retarding or friction device for the stem is located just beneath the bottom plate of the receptacle in an opening in the table top, and comprises a housing 26 preferably of cast metal in U-shape, in which are located the two friction blocks 27 and 28. These blocks lie parallel with the stem 13 diametrically opposite each other and have leather facing strips 29 at their inner faces frictionally engaging the stem 13. The friction block 28 is held in adjusted and fixed relation with the stem by a set screw 30 which bears against the block and is threaded in the housing, but the friction block 27 is designed togrip the stem, or be released therefrom, the former, action for the purpose of retarding downward movement of the stem or actual holding of the stem, and the latter condition to permit the lifting, by free motion, of the stem and movable bottom. To this end the block 27 has a cam notch 31 cut in its outer edge, and within the cam notch a roller 32 is located, a light spring 27 being used for holding the block 27 against the roller 32 to hold the stem from dropping, but permit the stem to be moved or pushed down by hand pressure on the ring 19.

The housing 26 is suspended beneath the 9 table top by its brackets 33 that are pivoted at 34 to the bracket arms 35 of the bottom plate of the receptacle, and a spring 17 coiled about the stem acts as a cushion against the bottom of the housing when the bottom 14 is lifted.

On the stem 36 in Fig. 1 a spool 37 may be retained to provide convenient cord for tying the completed bundle, and at 38 in Fig. 1 a paper tape holder for gummed tapeis indicated for customary use.
