To all whom it may 05mm Be it known that I, MILTON Wnrrnnmrnn,

a citizen of the United'States, residing at Baltimore, in the State of'Maryland, have invented certain new and-useful Improvements in Machines forRotating \Vrapped Articles to Enable the Wrapper Ends to be Twisted, of which cation.

This invention relates to improvements in machines-for rotating wrapped articles to the following is a specifienable the twisting of the wrapper-ends to secure thesame about a wrappedia-rticle;

The. invention is particularly designed t0 handle articles whose shape. is such as will permitof rotating the article such for example, as fci'gars, candies and similarlyw through the machine case,th e se'ction'being taken on the line 5-5 of Fig. 3. Fig. 6,

shows a perspective detail 'of -a wrapped cigar whose wrapper. end has passed through the first stage of the twisting and Fig. .7 illustrates the wrapped cigar wherein the. twisting of the end hasbeen conductedto a point where it has been coiled.-

In practice the machines are supported on a suitable bench or table, 1, which latter is provided withan opening or cut-out, 2, so that the body or casing, 3, of the machine may be suspended therein. In 'the present instance the body or casing, '3, is formed fromstitf sheet metal and is of a substantially rectangular shape in that it has two parallel side walls, 4, and, 5,.and two end walls, 6, and, 7, respectively. Each side wall, 4, and, 5, ofthe body or casing has a central vertical slot, 8, through which a shaft, 9,:en'tends. Onthe outer side, each side wall" carries a vertically extending bearing bracket 10, by means of whichthe shaft,

avertical slot,- 11, so that set-bolts, 12, which are rigidly secured to the side walls may pro ect through the bracket slot and by means of. nuts, 13, Willenable the brackets to be adjusted vertically so that shaft, 9,

may be raised or lowered. in the slots, -8, of

the body or casing. A pulley, 1 1,,is carried on the intermediate portion of shaft, 9, be-

tween the side walls of the casi'ng, and a driving pulley, 15, is-carried on the miter end of said shaft through which the shaft is revolved. i 1

body are provided with, angle plates, 16,

g which seat against the bench'or table, 1, and

"servefto sustain the body or casing pend antly 1n the opening, 2, with the upper end of the casing above thetable and the lower endthereofbelow the same, as"shown in .Figs. 1 to 4 in the drawings. Abo.ve the table,- 1, each side Wall, 4, and, 5, of the body or casinghas an-inclined edge, 17,

which extends upwardly in a direction from.

the: front wall, 6, toward tliexrear wall, 7 thus making each sidewall longer adjacent to tlierear wall than at the front, and each inclined edge is provided'with a semi-circular notch, 18,-for a purpose which will presently be explained. The longer rear edge of, each side wall has a forwardly curved arm, 19, which-curves over the inclined edge portion and said arms sustain'a horizontal ace, -Seach side wall is provided witha vertical bar, 21, which is rigidlysecured to the which eXtendsoutwardl-y for a purpose now to be explained. V

The'bracket plates, 24, and,. 25', respectively, ofsubstantially like construction and one for each side wall are utilized' Each plate has'a circular portion, 26, whose edge conforms in shape to the semi-circularnotch, I

18, insaid side walls and fits into said notc'h,

the pin or bolt, 23, on ban- 21, projecting outwardly through tl 1e said circular portion and pivotally sustaining-the same in register The end walls, 6,"an'd, 7, ofthe casing or guide pulley, 20. On the inner side or sur- I with the notch. Each plate also hasa shoulorder, 27,- which extends later'allyfrom one end of the' circular body so as, to rest upon the inclined edge, 17 of the side wall when the bracket plate is in the normal open position, as shown in Fig; 3, and each plate is fur ther provided with an upwardly-extending arm, 28. A guide roller, 29, is sustained between the upper, ends of arms, 28, and is movable with 'said arms *ina direction toward or from the roller, 20, on the stationary arms, 19, as'will presently appear. The

plate, 25, has a pin, 30, and the side wall, 5,

sustains an arm, 31, while a spiral or coiled spring, 32, isstretched between said pinand arm to apply a constant pull on the plate in a direction that would draw roller, 29, toward roller, 20. In like manner plate, 24, has a lever, 33, which is rigid therewith while wall,-'4, has the arm, 34, so-that a spring, 35, may be stretchedbetween said.

lever and arm to' exert the pull.

By referring to Fig. 3 it will be seen that the circular portion, 26, of bracket plate, 25, carries a stop plate, 36, while said wall, 5,-is provided with an adjustable stop screw, 37,

which the plate may strike when the portion,

-.end may be pivotal-1y connected to the end of lever,;;39. The arrangement of these 1e-' vers and linkssare such that to hold the bracket plates,'24, and, 25, and roller, 29,

away from the roller, 20, the treadle, 42, will be depressed as shown in broken-lines in Fig. This operation will throw the pivot, 44,."o fi-ijlever', 39, and link, 38, to the position also'shown in broken lines in. said Fig. 1,-the lever and link thus being in a straight line at this timeand consequently the springs, 32, and,.35, cannot move the-- plates, 24, and, 25, together. By moving the treadle, 42, sufficiently to move the pivot, 44, slightly to one side and thus' get lever, 39, and link, 38, out of line, whereupon, the springs, 32, and, 35, will act-on the plates, 24, and, 25, .and move them and roller, 29, toward the roller, 20, as shown in. full lines in Fig. 1, and by brokenlinesin Fig. 3.

An endless belt, ,45,-extends around the pulley, l4, -t-hen passes upbetween the walls of the body or casing, being directed in its travel by suitable crosspins or bars, 46, then extends around gui'depulley, 29. After leaving guide pulley, 29, a loop, 47, is formed in the pulley by means of a swinging or floating roller, 48, which is carried on a yoke-frame, 49, whose ends, 50, are yield- .65

means F1 and,

the upper ends of the plates, 21, on the inner side of the side walls, 4, and, 5, as shown in Figs. 2 and 4 of the drawings From the floating roller, 48, the belt passes up and over guide pulley, 20, and from the latter returns to pulley, 14.

The operation is as follows :The wrapper, 52, either paper or tin foil or both is first rolled about the article or cigar, either by hand or by means of a machine,- and the projecting ends of the wrapper may be either loose or partially twisted as shown at, 53, in Fig. 6. An example of a machine by which the wrapper is applied to the article and twisted, is shown in copending application, executed and filed on even dates with the present application. The cigar or other article with the wrapper thereon is placed in the looped portion, 47 of the belt, 45, while the same is in the position shown in Fig. 3, of the drawing. At this time it will be noted that the belt,45, while extending about the pulley, .14,-,.is not in driving contact with the same. The pulley, 14, however is revolved. continuously but does not drive the belt when the roller, 29, is swung down b the plates, 24, and, 25, which produces t e slack in thebelt that allows the latter to simply drop-around the pulley, 14. When the cigar isp aced in the loop of the belt, the two twisted ends, 53, are held by the fingers of the two hands of the operator, substantially as shown in Fig. *4. The treadle, 42, will then be actuated so as to raise her, 41, and the springs, 32, and, 35, willimmediately draw the,plates, 24, and, 25,'toward arms, 19, thereby moving roller, 29, toward roller,.20, so as to inclose the cigar in the loop of the belt, as shown in .1 This movement of the plates, 24,

25, draws the belt, 45, into close contact with pulley, 14, and the belt immediately begins traveling so as to efi'ect a revolution of the cigar. By simply holding the ends of the Wrapper while the cigar is revolved the said ends willt wist and form a coil,the ends gradually shortening as the ,coilingyprogresses, and when the ends are 'coiled'closely against the ends of the package as shown at, 54, in Fig. 7, the operator will depress treadle, 42, and pull down bar, 41, thus moving the lever, 39, and link,

38, so as'to throw roller,29, away from roller, 20,- This movement opens the loop, 47, in the belt and the wrapped package is immediately removed, while at the same time the' belt will cease to travel.

\ Having thus described my invention what I claim and desire to secure by Let ters Patent is 1. The combination with a casing, of a pulley; a belt; a roller engaging and forin ing a loop in the belt to receive the article and Wrapper; means for closing the loop of the belt about the article and wrapper and simultaneously setting the belt in motion whereby to rotate the wrapper and article. 2. The combination with a casing, of a pulley; a belt extending around but normally out ofoperative contact with the pillley; means for normally maintaining an open loop in the belt while the latter is at rest whereby the article and wrapper may be placed in said open loop, and means for closing the loop about the article and wrapper and setting the belt in motion.

V the treadle with the pivotally-sustained ter arms; t-readle means for moving said bracket plates whereby tomove "the latter and the roller carried thereby; an endless belt in the hollow casi'ng,said' belt pass-.

ing around the pulle and also around said two rollers, and a third roller engaging the outer side of the endless belt between said two rollers to form a loop in said belt,

4. The combination with a hollow verti cal casing having side and end walls and having spaced-apart roller-supporting arms at the upper end, of vertically-adjustable bearing plates sustained by opposite walls of the casing;'a shaft carried bysaid plates; a pulley carried by the shaft and on the interior of the case; a roller rotatably mounted between the said arms'of the casing; another pair of roller-supporting arms pivotally carried by and movable with respect tothe casing; a roller supported by said latlatter arms and roller; an endless belt passing around the pulley and also around the said two rollers and means sustained between said two rollers for engaging the outer side of the'endless belt to form a'loop in the latter between sa'id'two rollers.

5. The combination with a casing having a side wall with an inclined edge which latter is provided with a semi-circular recess and said wall also having roller-supporting arms extending above said recess, of a guide roller carried by said arms; bracket plates having a circular portion to enter said semicircular recess and also having, a guide roller-supporting arm; a roller carried by said bracket plates.

said latter arms; adri'ving pulley below said semi-circular recess; endless belt passing around said driving pulley and also around the said --two guide rollers, and means acting on the outer side of the 'endless belt between said roller-supporting arms to form an inwardly-extending loop insaid belt. r
