Holders, of which tlie following is a specification.

This invention relates to a cord holding device for grain binders of the McCormick type, the object of the invention being to provide a simple and effective means for preventing the cord from slipping into the offset of the slotted opening provided in the breast plate for the knotter frame before the knot is fully tied and the cord severed by the knife.

lVith the above, and other objects in view, which will appear as the description progresses, the invention resides in the novel construction and combination of parts here inafter fully described and claimed.

In the accompanying drawings, Figure 1 is a top plan view of the breast platefor the knotting frame of an ordinary McCormick grain binder. Fig. 2 is a side elevation of the knife and cord holder of an ordinary McCormick binder. Fig. 3 is a top plan view of the plate employed with my im provement.

The revoluble knife 1 comprises a central circular plate 2, the upturned blades 3 being arranged at opposite sides thereof and having oppositely disposed cutting edges. The knife, as usual, is attached to the lower side of the cord holder 4 of a McCormick binder, as described in Letters Patent of the United States, #dtQfi, and revolves therewith. The knife head is secured for rotation upon a suitable shaft 5. The breast plate 6 is also of the usual construct-ion provided by the said McCormick binder and has the elongated slot 7 provided with the offset curved portion 8 which forms the shoulder 9 between the slots 7 and 8. The numeral 10 designates the finger which holds the cord in position to be caught by the knotted bill, which in this instance is not illustrated. In the ordinary construction of these parts and especially after the parts have become a little worn, the cord frequently slips from around the finger 7 and the shoulder 9, thus losing many bundles or causing the same to fall without being properly tied.

It is the object of the present invention to obviate this fault and to overcome the de- Specification of Letters Patent.

ficiency I have provided the body of the breast plate 6 with a substantially L-shaped catch member 11. This catch member is pivoted to the plate as at 12 and has one of its offset arms provided with a finger 13, the same being adapted to lie directly over the shoulder 9 and to extend directly above the slots 7 and 8 as illustrated in Fig. 1 of the drawings. The opposite arm 14 of the member 11 is adapted to be contacted by diametrically opposite oifset members 15 provided upon a plate 16, which is secured to the under face of the knife 2 through the medium of suitable removable screws 17 The offsets 15 are adapted to lie directly forward of the knife blades 3, as clearly illustrated in Fig. 1 and the said offsets are adapted to contact with the member 14 of the catch 11, before the knife blades 3 sever the cord.

The numeral 18 designates a flattened spring which has one of its ends connected with the side of the breast plate as at 19, and its opposite end contacting with the off set arm 14 of the catch 11. The spring is adapted to exert pressure upon the said arm 14 so as to force the lip 13 of the catch 11 in one direction and this movement is limited through the medium of a stop member 20.

From the above description, taken in con nection with the accompanying drawings, it will be noted that the cord cannot pass into the slot 8 without first contacting the finger 13 of the catch 11, and it will be further noted that by positioning the knives 3 to the rear of the offsets 15 the binding cord cannot be prematurely caught by the knife, and the operation of the machine in the formation, binding and tying of the gavels is rendered certain.

The operation of the binding, knotting and cutting mechanism is well understood by those skilled in the construction and operation of the McCormick grain binder and is hence not stated here, and only so much of the mechanism of the McCormick binder has been illustrated as is needed to illustrate the operation of my improvement in co-action therewith.

Having thus fully described the invention, what I claim as new is The combination with a breast plate of a knotter frame having a slot provided with an offset portion, of an L-shaped catch member pivotally connected with the breast plate and having one of its arms provided with an offset adagted to normally partially close the opening of the breast plate at the ofiset thereof, the breast plate being P1()Vll0(l with a projection uda ited to limit the movement of the L-shaped member in one direction, a spring secured to the breast plate and adapted to-contact with he straight arm of the iL-shaped member to force the opposite arm against the stop of the breast plate a rotary cord holder a knife member secured to the under face of the cord holder, said knife member comprising a disk having oppositely disposed upx'vardl" extending cutting portions, a second disk secured to the knife ineniber said second disk being provided with oppositely arranged arms arranged forward of the cutting members of the knife and the straight arm of the L ieped member being positioned Within the the arms of the said second disk so as to be contacted thereby when the disk rotates thus rocking the said i. shaped member against action of the spring.

in testimony whereof it ailix my signature in presence of two Witnesses.
