Stringing tobacco stalks on a tobacco stick.`

The object of the invention is to provide a simple machine adapted to be readily operated and capable of rapidly and effectively Stringing tobacco stalks on a tobacco stick.

The invention consists in the construction,

combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

Figure 1 is a perspective view o-f a tobacco spearing machine constructed in accordance with this invention. Fig. 2 is a side view of the same with a part of the frame broken away. Fig. 3 is a cross-section of the same on the line 1 -4 of Fig. l. Fig. l is a perspective view of spring hook device on inside of plunger. Fig. 5 is a detailed view of the flexible spring hook, illustrating the means of conmmnicatin motion to the sliding boards of the machine and of breaking that communication.

Similar characters refer to similar parts throughout the several views.

Fig. l is a perspective view of the tobacco spearing machine, in which a, a represents the frame. This frame is composed of a center beam of wood f, of sufficient strength to support the two side pieces z' z', and the other working parts connected therewith, which is further strengthened by acrosstie y", on the under side at the end of the side frames z' i. The center beam f, has on either side a wooden frame j j, provided with a dovetailed groove a; alone its entire length forthe support of the sliding boards g g, and the two side pieces z', are also provided with like dovetailed grooves on their inner side for the support of the plungers c c. The sliding boards g, g, are each .made onehalf the length of the frame a and are provided with dovetailed tenons y so constructed as to slide in the grooves freely from end to end of the center beam f. The plungers are also provided with dovetailed tenons y y', to slide in the dovetailed grooves 00 w in the side pieces z'. Fastened at convenient distances on the sliding boards g g are a series of iron guides Z Z which are bolted to the sliding boards by the bolts 76,' the :number of these guides being proportioned to the size of the machine and the number of tobacco stalks desired to be strung on the tobacco sticks p p. These iron guides d (l are provided with V shaped notches m, m, on each face front and rear extending up and down, and with grooves a n in their upper4 surface cut parallel to the face of the sliding boards g g and of suflicient depth and width to contain the tobacco sticks p p. r

At the rear end ofthe machine is a crank shaft b withl a cogv wheel Z in its center and attached to the center beam f so as to mesh into another cog wheel of a smaller size on any suitable power shaft. inasmuch as the Y power shaft forms no part of this invention and as its method of connection is sufficiently obvious 1t 1s not shown.

lhe crank shaft Z) has reciprocating cranks 0 0 to which are attached iron rods or crank arms e e connecting the cranks o o to the plungers c c. The plungers c c move in the dovetailed grooves of the side pieces c' c' forward and backward a distance equal to the diameter of the circle made by a revolution of the cranks 0 o, and by means of a device hereafter described communicate their forward movement to the iron guides Z d of the sliding boards g g forcing these, boards forward intermittently. At the forward end of each plunger c is fastened a plunger-head or feeding device 7L; this plunger-head or feeding device L is a triangular piece of wood or iron attached to the inner faces of the plungers, one at the top and one at the bottom, and extending over and under the iron guides (l d almost to the faces of the sliding' boards g g, but so ads. -V shaped notches m, m, ofthe iron guides l al.

In appropriate places in the plungers c c holes are cut of suflicient length and width to permit the hook s to move uninterruptedly in the face of the plungers c c when desired by the operator, and to engage itself with the rear end of any desired iron guide when uncontrolled. Saidhook s is Vthe bent end of a piece of iron or fiexible steel t fastened at one end by a bolt fu to the inner face of the hole or mortise cut in the face of the plunger c. If this hook arm t is made of iron a spiral spring not shown is placed in the plunger at its back to force it outward when released from control, but if it is made of flexible steel as shown the spiral spring may be dispensed with. The flexible hook arm is controlled by the following device.

Through the top of the plunger-head or feeding device 7L and also through the bottom in a vertical line holes are made through which a rod u is rotatably mounted, having a handle-piece u at its upper end and an offset u. intermediate its ends.

The rod a has its handle u lying flat upon the top of the plunger-head h and is always under the control of the operator. By a movement inward the offset portion u of the rod u presses the hook arm t inward releasing the hook s from contact with the iron guides, thus permitting the plungers to move uninterruptedly forward and backward while the operator is preparing another stalk for spearing. Then ready, the handle piece u is moved outward releasing the pressure of the offset portion u, and the tension of the hook arm forces the hook s outward, ready for engagement with any iron guide which may lie in its path. The hook s is bent at an acute angle with the body of the hook arm so as to form an incline cam surface s. During the backward movement of the plunger the cam surface s contacts with the iron guide next in its way and is forced toward the face of the plunger as shown in dotted line t of Fig. 5, permitting the hook end s to pass the guide; upon the forward movement of the plunger, the hook having positioned itself engages the rear of the iron guide and advances the sliding board one step. The reciprocating motions of the plungers coupled with the action of the hook intermittently moves the sliding board forward.

In the forward end of the frame a on either side a support c is provided having a slot s in its upper surface, for the support of the butt end of the tobacco stick p, its point resting in the groove of the first iron guide as shown in Fig. 2. The operation of the machine is as follows. The tobacco stick p is positioned as shown in Fig. 2. The operator then places a tobacco stalk with its but-t end up in the V shaped notch of the iron guide (l, releases the handle piece u which causes the hook s to engage the nearest iron guide and force the sliding board forward causing the V shaped notch in the plungerhead or feeding device 71. to close upon the tobacco stalk @c and center it exactly in line with the point of the tobacco stick, which by reason of the advancing movement of the sliding' board is forced through the exact center of the tobacco stalk and'down the stick the full length of a plunger advance. Inasmuch as the plunger will move several times faster than the most skillful operator can feed the device the hook s must be kept out of the way of the guide irons. To do this the operator simply pushes the handle piece u inward which forces the hook arm t inward and holds it at the will of the operator. When another stalk is positioned in the V shaped notch of the second guiding iron and the handle piece released, the stalk is again centered by the advance of the V shaped notch in the plunger head or feeding device and impaled upon the tobacco stick, the first stalk'being forced a corresponding distance forward. By a repetition of these processes t-he tobacco stick is filled Yas shown in Fig. l, the vertical dotted lines representing the impaled tobacco stalks and the horizontal dotted line the tobacco stick. This stick with the impaled tobacco is then lifted out of the grooves in the guide irons, and the sliding board pushed back to the crank end of the machine and another to bacco stick inserted as shown in Fig. 2.

lt is understood that a separate stick is used for each operation, the head being removed after each operation and placed on the end of the spear or stick next to be used. The stick or spear head forms no part of this invention. The advantage of this tobacco spearing machine in point oflabor is very apparent. It is cheap in construction, easy of operation and thoroughly practical.

lVhat I claim as my invention and desire to secure by Letters Patent isl. n a machine of the class described a tobacco holding device, a support therefor, means to support a tobacco stick, a feeding device constructed and arranged to impale the tobacco upon the stick and to intermittently advance the tobacco holding device when a tobacco stalk is in place.
