KNOTTER.

' SPECIFICATION forming part of Letters PatentNo. 727,424, dated May 5, 1903.

Application filed February 5, 1902 Serial No. 92,679. (No model.)

T aZZ whom, it may concern:

Be it known that I, OLOF WILLIAM ORELL, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented new and useful Improvements in Knotters, of which the following is a specification.

My invention relates to knotters; and the object of the same is to construct a hand-tool by means of which a string may be knotted to secure it around a bundle, bale, or package. The simple and novel construction by which this object is accomplished is fully described in this specification and claimed, and illustrated in the accompanying drawings, forming a part thereof, in which Figure 1 is a perspective of my device. Fig. 2 is a side elevation of the same. Fig. 3 is a detail perspective of the thread-guide, thread-clamp, and cutter. Fig. 4 is a detail of the upper jaw. Fig. 5 is a detail of the pinion.

Like characters of reference designate like parts in the difierent views of the drawings.

The operating parts of my tool are all carried by two movable jaws, an upper and a lower jaw, (designated 1 and 2, respectively,) which jaws are operated by handles 3 and 4. A spring 5, mounted between the jaws, serves to hold them normally in a separated position.

Mounted on the lower jaw 2 is a knotter 6 of the ordinary beak type and having a fixed The jaw 7 is rounded off on the back at 7 to prevent its engaging the standing part of the thread. The movable jaw 8 extends rearwardly beyond the pivot and bears a roller 8, located to be engaged by a curved arm 9 to close the beak to grip the thread. The knotter 6 is carried by a shaft 10, journaled in the ends 11 of a rectangular frame A, carried by the jaw 2 and having sides 12. The shaft bears a small pinion 13, which is set to mesh with a rack-bar 14, carried by an arm 15, pivoted to the upper jaw'l; The pinion 13 has a cam 13 formed integral therewith, which has a fiat side 13, which faces the arm when the knotter is in its normal position, and thereby keeps said knotter from turning. The arm 15 extends parallel to one side 12 of the frame A and is made narrower than the length of the side 12 to permit a pivotal motion, which enables the rack 14 to engage the pinion 13 on the downward movement of the jaw 1, but to be displaced so as to clear it on the return. movement. In order to operate the arm 15 in this manner, a rounded projection 16 is formed on the upper end thereof, which projection engages the outer end of the frame and displaces the arm 15 inwardly. A rounded toe 17 is formed on the lower end of the arm 15, which toe engages the rear of the frame A and serves to restore the arm to its initial position with the rack in line with the pinion 13. To hold the arm 15 true during the operation of knotting, guide-grooves 18 and 19 are formed in the face of the arm 15, which grooves intersect at 18 and 18 and engage a stud 20, seated in one of the sides 12. Apertures 15 serve to permit the rotation of thecam 13 carried by the pinion 13, and therefore of the pinion 13, during the time it is engaged by the rack. I

As before stated, the closing of the beak of the knotter 12 is performed by the arm 9, which operates the movable jaw 8. To open said jaw to engage the thread, a circular cam 21 is provided and surrounds the shaft 10 in position to engage the rear end of the jaw 8. The face of the cam 21 is beveled and terminates in a square shoulder 21, which marks the release-point, after which the jaw is engaged by the arm 9.

In order to sever the binding-twine, a cutter 22 is provided and comprises a movable jaw 23, bearing a knife 23", located adjacent to a slot 24E, formed in a plate 25, formed integral with the frame A and extending parallel to the shaft 10. A spring 26 is attached to a lug 27 on the jaw 23 and operates to return the jaw to its normal position. A beveled cam 28 is rigidly mounted on the jaw 1 in position to engage the lug 27 to operate the jaw to sever the twine.

A thread-holder 29 is mounted at right angles to the plate and comprises an arm 29, having a hook 29 formed thereon. A threadclamp 30 is located beneath the plate 25 and has two serrated jaws 31v placed in line with the slot 24;,and in position to engage the thread passing therethrough. A set-screw 32 bears on one of the jaws, which is of thin resilient metal, and thereby regulates the grip of the jaws and the adjustment for different sizes of twine.

The operation of my device in the operation of'tying a package is as follows; The twine is first passed around the package and the two ends then grasped in the left hand, while the tool is held in the right hand, with the arm 29 of the thread-guide 29 pointing up. The free ends of the twine are then engaged in the hook 29 of the thread-guide and drawn taut and then given one turn around the beak of the knotter 6, after which they are brought down and secured in the clamp 30. Thehandles 3 and 4 are then actuated by the right hand, which action will bring the rack 14c into engagement with the pinion 13, which will rotate it, and thereby revolve the knotter 6 until the rear end of the jaw 8 'is engaged by the cam 21 and actuated to open the beak of the knotter. The knotter 6 will continue to rotate, which will cause the open beak to engage the standing part of the twine passing down through the clamp 30.

lug 27 on the jaw 23, thereby operating said movable jaw to sever the thread. Simultaneously with the severing of the thread the projection 16 will be brought into contact with the frame A and the arm 15 displaced backwardly. The handles of the tool are then released, when the spring 5 will restore the jaws 1 and 2 to their initial positions. On the return the rack 14 will not engage the pinion 13, owing to the displacement of the arm 15 by the projection 16. As the jaws snap back into their initial positions the toe 17 will engage the frame A and push the arm 15 back into its initial position.

I do not wish to be limited as to details of construction, as these may be modified in many particulars without departing from the spirit of my invention.

Having thus described my invention, what I claim as new, and wish to secure by Letters Patent, is

1. In a hand-knotter, the combination with upper and lower movable jaws provided with handles, a shaft journaled in said lower jaw and bearinga pinion, a knotting-beak mounted on said jaw, a cutter, a pivoted arm carried by said upper jaw and arranged to operate said cutter, guides for said pivoted arm, and a rack mounted on said arm and located to mesh with said pinion, substantially as de scribed.
