9 Claims. (Cl. 214-5.5)

In preparing tobacco for the market, the tobacco is brought from the field in the green state, strung on sticks, and hung in a tobacco barn where it is cured by artificial heat. It takes about a week to cure out a barn. About six hundred sticks of tobacco are hung in a barn about sixteen feet square and fourteen feet high. The barn is fitted inside with tier poles, set about four feet apart and arranged in rooms so that the tobacco rests in layer above layer, extending from about six feet above the floor to the caves of the barn. The tobacco is strun on the sticks in bunches of about three leaves to the bunch. The bunches, called hands, are arranged about sixteen hands on either side of a stick. The conventional method is to place a stick in a horse, i. e., a frame that support the ends of the stick. Ordinary wrapping string is used, and the hands are secured to the stick by making a turn or wraparound the stems.

My invention has to do with the securing of the hands together and to the stick, and it has for its objects:

1. To provide a simple, inexpensive apparatus for looping the cord about the hands and locating the hands on the stick.

2. To provide a tobacco looper by whose use the hands are so held on the stick that, no matter how the stick is held in transferring it from the looper to the tier poles, the tobacco will remain on the stick.

3. To provide a means to secure the hands to the stick in such position that the lower ends of the hands are held out away from the stick so that heat is permitted to pass through them and thus effect a better cure than with other methods of looping.

To the attainment of the aforesaid objects, my invention resides in the novel features of construction, combinations, and arrangements of parts, which will hereinafter be described in detailand will then be specifically pointed out in the appended claims, reference being had to the accompanying drawings in which- Fig. 1 is a side elevational view of a tobacco looper embodying my invention.

Fig. 2 is an enlarged detail plan view of a poraim of the same, looking in thedirection of the.

arrow a in Fig. 1, and with the cross arm rotated 90 from the position shown in Fig. 1.

Fig. 3 is a detail elevation of a portion of the looper, looking in the direction of the arrow b in Fig. 1, and on the same scale as Fig. 2.

Fig. 4 is-a cross section on the line 4-4 of.

Fig. 1.

2 Fig. 5 is a detail section on the line 55 of Fig. 2.

Fig. 6 is a detail section of one form of cordtensioning means that may be used in my apparatus. Y

Fig. 7 is a diagrammatic view illustrating the kind of loop that can be made by the use of my invention.

In the drawings, in which like numerals and letters of reference indicate likeparts in all the figures, I represents a base board to which cross pieces or feet 2 and standards 3 and 4 are suitably secured. The standards 3 and 4 are each composed of a pair of parallel bars 3, 4 between whose upper ends is secured a saddle block 5. The standards 3 and 4 are suitably braced as at 6 and 7 respectively. The stick S is held in the V-shaped top end, 5 of the saddle blocks 5 by a spring latch 8 suitably mounted on the stand-- aid 3. r Tables 9, right and left sides, are mounted on the standards 3 and 4, on which the tobacco leaves may rest while the looping takes place.

A foot pedal IIJ lies between the bars 3 3 and 4 4 and is pivoted to the bars 3*, as at l I for a purpose presently to appear.

The posts 3 and 4 are spaced apart a suitable distance to hold the stick S, the post 3 being located adjacent one end of the base board I. Adjacent the other end of the base board I is a post l2, braced at l3, and secured to the adjacent foot 2.

Between the post [2 and standard 4 and adjacent post l2 are bearing ears 22, between which is pivoted, at 2|, a supporting post l4 having a shaft bearing l5. A pair of spaced pedal-guide bars l6 are held parallel to the post l4-by the blocks l8, l9 and 20 and support a second shaft bearing 11.

The pedal l0 projects between the bars 16 and has a suitable pivotal connection 21 to rack-rod 26 whose rack 26 engages a pinion 25 on a hollow shaft 24 that is mounted in the bearings 15 and IT. The post 14 and its carried parts are held in which two cord spools or bobbins 33 aresuiti; ably held. The cords C and C pass from the 3 bobbins 33 through cord-tensioning devices 3! that are located on the post Hi and from thence the cords pass through the hollow shaft 2 where they divide, one cord C passing through one tensioning device ti on the cross arm and through one eye lit, while the other cord C passes through the other tensioning device 3! on the cross arm and through the other eye 39.

The rack 26 and pinion are so designed that the shaft can turn through one revolution only, back and forth. To this end the movement of the pedal it is limited by suitably located stops secured between the bars i (see Fig. 1). A return spring 3t, secured to the pedal and anchored at 33 to the bars l6, returns the pedal to its elevated position with the cross arm 28 in vertical (normal) position.

Operation In operating my machine, two persons (called feeders) are provided, one at either side of the machine. The first operator (the feeder at one side of the machine) takes a tobacco stick and fastens strings or cords C and C to the stick about siX inches from one end. This is best done by knotting the ends of the cords or strings together and then making a noose over the end of the stick, thus providing a knot for the first hand of tobacco to rest against.

The stick is then placed on the standards 3 and i and the knotted end of the cord. and the stick are held down securely under the spring clamp or latch 8 so that proper ten. ion may be applied to the cord. The tensions should be so adjusted as to just hold the tobacco in place and keep the cords from flopping as the cross-arm turns.

The other operator (the feeder at the other side of the machine) now inserts a hand of tobacco and steps on treadle it. This causes cross arm 23 to make one complete revolution, thereby putting a twist on strings or cords C and C close up to the tobacco. The first mentioned operator (hereinafter called operator A) now inserts a hand, pushing it up tight against the first hand and the second mentioned operator (hereinafter called operator B) releases the treadle ill. Spring 3% causes the treadle to rise and thereby return cross 28 to its initial position, placing another twist on the strings and securing the second of the hands in place. These operations are repeated until the stick contains the desire-cl amount of tobacco. Opera ator B then pulls out enough string to tie the tobacco to the stick, breaks the string and hands the loose ends to operator A, who knots them together and gets the next stick ready while operator B finishes tying the string to the loaded stick.v

As operator B lifts the loaded stick from the. standards 3 and i, operator A inserts or places a new one in position.

By pivoting the cross arm to the shaft, provision is thereby made for the arm to give with any unusual strain on the strings and still hold both strings tight.

In adjusting the inclination of supporting post M it should be so tilted that the axis of shaft 24 will line up with the stick at latch 8 and the cross arm should lie normal to this axis, as shown in Fig. 1. Spring 23 should be adjusted so that its pull, will not be too strong. In case an operator, in feeding the machine, should strike one of the strings harder than the other or thrust his hand in. hard enough to cause the strings to pull through the guides, the spring 23 should give and permit the cross arm to swing forward and ease the strain. This arrangement holds the strings at the proper tension, where otherwise a violent move on the part of an operator could cause one or both strings to feed through the tensioning devices and become slack and catch on the tobacco stick.

V/hile I have shown and described my machine as manually operated by foot pedal, it is possible for it to be motor driven by inter-posing any suitable known means for translating the rotary motion of the motor into reciprocating motion in rod 26, all Without exercising more than mechanical skill.

While I have shown the arm 28 as pivoted to the shaft 23, the arm could be made fast to the shaft 2 4 although it probably would not operate as satisfactorily as the pivoted arm. Furthermore the spring tension device 3| on one side of the arm for one of the strings can be omitted and the corresponding spring tension device 3! on the post made to perform the required tension. In other words, for each string one tension device 3! on the post and one tension device on the can be employed and adjusted so that the tensions on the two strings will be equalized, though I prefer to use the two sets of tension devices as shown.

Other modifications will be obvious to those skilled in the art without departing from the scope of the appended claims.

From the foregoing description, taken in con nection with the accompanying drawings, it is thought that the construction, operation and advantages of my invention will be clear to those skilled in the art.
