Serial No. 534,787.

To all whom it may concern:

Be it known that I, CHARLES Gr. WVELLs, a citizen of the United States, and a resident of Rockyhill, in the county of Hartford and State of Connecticut, have invented a new and Improved. Tobacco-Stringing Machine, of which the following is a specification.

My invention relates to the class of devices above named, and the object of the invention is to provide a device of this class having novel features of advantage and utility. I

One form of apparatus embodying my invention and in the use of which the objects sought may be attained is illustrated in the accompanying drawings, in which Figure 1 is a top plan view of a device embodying my invention with parts broken away to show construction and the needle being shown as near the end of its path of movement backward. Fig. 2 is a view in front elevation of the same, with parts broken away to show construction. Fig. 3 is a detail view on enlarged scale of one of the leaf supporting arms. Fig. -1- is a like View of one of the clamp arms. Fig. 5 is a detail view on enlarged scale of a portion of the device showing its manner of operation, the locking bolt feature being omitted as unnecessary to an understanding of the operation illustrated. Fig. 6 is a detail view on enlarged scale in section through a portion of the needle carrying wheel. Fig. 7 is a detail view showing a slightly different form of construction of the clamping parts.

In the accompanying drawings the numeral 6 denotes a base constructed of any suitable material and of any desired form to properly receive the special construction of apparatus which may be placed thereon. This base may be supported in any suitable manner, as shown herein it being adapted to be secured to a bench or other support, semipermanently as by means of screws, nails or the like, passed through openings 7 in the base. A crank shaft 8 having acrank handle 9 is mounted at one end of the base, a bevel pinion 10 on the crank shaft meshing with a bevel gear 11 secured to a driving wheel 12 mounted with its axis arranged vertically on the base. A needle carrying wheel 13 is also mounted with it axis vertically arranged on the base, each of these wheels having two grooves 14, one of said grooves 15 in the wheel 13 having a needle groove 16 at the bottom thereof. Straps 17 are secured to each of the

wheels

12, 13, a strap being located in each of said grooves 14 in each of the wheels and so arranged that when the driving wheel 12 is rotated in one direction one of the straps will exert a pull upon the wheel 13 causing its rotation in an opposite direction, and the opposite strap will, be pulled by the wheel 13 from the wheel 12, and in a movement of the wheel 12 in the opposite direction, the action of the straps will be reversed.

A flexible needle bar 18 is mounted in the groove 16 in the wheel 13, this bar lying under one of the straps 17. The end 19 of the bar is formed into a hook. In the form of construction herein shown this needle bar passes in contact with guide rollers 20 and through a. slot in a guide post 21. The guide rollers are mounted upon posts 22 secured to the base.

A support 23 extends from the base, in the construction herein shown this support being secured to a block 24: rising from the base. A series of leaf supporting arms 25 are secured to the support and arranged at suitable intervals lengthwise therealong, these arms projecting beyond the front edge of the support and having stem recesses 26. Needle openings 27 are formed through the arms near their ends for the passage of the needle these openings extending into the stem recesses. Cord slots 52 extend. from the ends of the bars into the needle openings 27. Clamp arms 28 are each movably supported with respect to a leaf supporting arm, in the preferred form of construction and as shown herein each of these arms being pivotally mounted upon the support 23. Springs 29 hold the clamp arms against the leaf supporting arms.

The stem recesses hcreinabove described may if desired be located on the clamp arms instead of the leaf supporting arms, but in the preferred form of construction and as Cir shown herein a portion of these recesses are located on each of said arms, every alternate leaf supporting arm and every alternate clamping arm having such a recess.

A releasing bar 30 is mounted on the edge of the support 23 and has a sliding movement permitted by screws 31 located in slots 32 extending through the bar. The springs 29 are secured to the support 23 and exert a yielding pressure upon the clamp arms sufficient to hold a leaf suspended between the two arms. Releasing pins 33 are secured to the releasing bar 30, one of these pins being located to operate upon each of the clamp arms. Any suitable means for operating the releasing bar may be employed, but I prefer to operate it from a moving part of the device. A satisfactory construction for accomplishing the result is shown herein in which a lever is mounted upon a pin 3 1 secured upon a depressed portion 35 in the block 24:. This lever consists of a cam arm 36 extending underneath the rim of the wheel 13, and a nose 37 engaging a re cess 38 in the bar 30. A spring 39 is employed to hold the lever in engagement with the shoulder formed by the recess 38. A cam 10 secured to the under side of the wheel 13 is located in position to operate the lever at proper times.

In the construction herein shown each of the clamp arms has a post 11 forming its pivot, which post extends into the support 23 and the end of each bar is recessed as at 42 to allow passage of the needle in the operation of the device. A locking bolt 43 is mounted at the end of the support 23 in position to engage a locking recess 41st in the bar 30, a spring 45 being employed to normally hold the bolt in engagement with the recess.

Brackets 416 project from the leaf supporting arm at the end of the support 23, these brackets each having a recess 4:7 for the reception of a cord 48 secured to the end of a lath 19.

In the operation of the machine the bolt &3 being engaged with the recess 44 in the locking bar, is first disengaged, and the stems 50 of leaves are located one between each pair of arms consisting of a clamp and a leaf supporting arm, the stem of the leaf being located in the recess as shown in Fig. 5 of the drawings. The lath t9 is laid across the ends of the arms 25 as shown in Fig. 5, the end of the cord as being placed in the recesses 47 in the brackets tti, the ex treme end of the cord being located at some little distance beyond the bracket. The crank handle 9 being turned to rotate the driving wheel 12 in the direction indicated by the arrow in Fig. 1, the wheel 13 is rotated in the direction also indicated by the arrow in said figure. This causes the needle to be forced through the stems of all of the leaves, passing through the needle openings 27 each of which, as shown by dotted lines in Fig. 1, is beveled as at 51 to guide the needle in its travel. lVhen the needle reaches the end of its travel its point engages the cord near its free end. By now reversing the movement of the driving

wheels

12 and 13 the needle is withdrawn from the stems, in this withdrawing movement pulling the cord through all of the stems, as illustrated in Fig. 5. As it withdraws from the last stem the cord also withdraws from the needle point. As the wheel 13 approaches the end of its movement, at about the position shown in Fig. 1, but moving backward, the cam 40 engaging the cam arm 36 moves it and the bar 30 backward until the bolt 13 shoots into the recess &4 holding the bar in this position, thus opening the clamp arms 28 and releas ing the leaves, which, however, are held by the cord on the lath. The end of the cord being now grasped it is passed out through the slots 52 in each of the'supporting arms, carrying the leaves with it, and its free end is made fast to the end of the lath, thus suspending the leaves from the cord on the lath. 7

It will be noted that the strap or belt 17 overlying the needle bar in the groove 16 holds said bar rigidly within the groove, thus preventing bucking action of the bar that would otherwise occur by reason of the resistance to the entry of the bar into the stems, and between the first pair of arms and the wheel 13 the needle is prevented from buckling by the location of the rollers 20 on opposite sides thereof. In the initial movement of the wheel 13 the cam 40 engages the lever 36 moving the nose 37 out of the recess 38 and without affecting the bar.

I do not limit my invention and the scope of the following claims to the devices of the foregoing illustrations and descriptions of the preferred form in which it is embodied, as these may be departed from to a greater or lesser extent without avoiding the invention.

The releasing bar is shown herein as about square in cross-section, but I contemplate making this bar quite thin, and of just sufficient thickness to receive the pins 33 and provide for the recess 38'.

While I have shown the needle bar as round in cross-section, I have found very satisfactory results to flow from one of a rectangular shape in cross-section.

The form of the device as shown in Fig. 7 is similar to that herein shown and de scribed with the exception that instead of mounting the springs 53 for the clamp arms 28 upon the support 23 these springs are secured to the releasing bar 30. The locking bolt in this construction holds the bar with the springs 53 pressed against the arms 28, the recess in the end of the bar being arranged to permit this function and when the bar is designed for mechanical operation the parts will of course be arranged to cause engagement of the locking bolt at the proper time to exert the function above set out.
