CORD-HOLDER FOR GRAIN-BINDERS.

Specification of Letters Patent.

Patented July 16, 1918.

Application filed January 31, 1916., Serial No. 75,362.

'United States, and residents, respectively, of Chicago, in the county of Cook and State of Illinois, and of Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cord-Holders for Grain-Binders, of which the following is a full, clear, and exact specification. I

Our invention relates to cord holders for grain binders. i

In the operation of cord 'holderscof the type described in the Benjamin Patent, No. 865,754, issued September 10, 1907', it has been found that an operator not familiar with the operation of the mechanism will more or less frequently, in an initial threading of the device, draw the cord from the needle through the slot in the breast plate and into the cord receiving groove of the rotatable cord holdingdisk, and will hold the end of the cord at a distance from the cord holding mechanism, and when the needle is brought upward and outward, it delivers another strand of cord to the holder and the knotting and holding mechanism, moving in unison, will carry the cords between the disk and cord holder plate while the knot is being tied and the two strands of cord severed by the knife. The knot is then stripped from the knotter hook and the machine is presumed to be in proper condition for further continuous operation, but one end of the length of cord held by the operator is still drawn between the disk and plate and will be carried around the disk shaft instead of being discharged, the result being that the plate and disk are separated to an extent that they will not perform their proper function of holding the cord.

Our improvement has for its object to provide an improved construction wherein even although the cord is improperly placed in the cord holder initially and the loose extra end of twine is left in the holder, the mechanism will operate efliciently and without any disorganization thereof due to the presence of the cord.

We obtain these objects by an improved construction of the cord holder plate carrying improved means whereby the cord that was in the hand of the operator is prevented from passing around the disk shaft between the plate and the disk and will be discharged from the mechanism.

In the accompanying drawings we have illustrated one embodiment which our in vention may assume in practice, showing the same in connection with a cord holder of the type described and claimed in the above mentioned patent.

In these drawings:

Figure '1 is a sectional plan view of the cord holding mechanism, showing the same improperly threaded and when the parts are beginnin the knotting operation.

Fig.2 is a view similar to Fig. 1, showing the result of improper threading, and also our improved means which prevents the en try of the piece of cord between the plate and disk. I

Fig. 3 is a top plan view of our improved cord holder plate.

Fig.4 is a side elevation of Fig. 3.

Fig. 5 is a .side elevation of the disk and plate, partly in section, and illustrating their cooperation.

V The mechanism shown in these drawings includes a breast plate 1, on which is mounted the usual rotatable knotter hook 2, rotatable cord holder disk 3, stationary cord holder plate 4, and fixed knife 5, these parts being of the construction described in the Benjamin patent mentioned above. As in that construction, the disk 3 rotates upon the cord holder plate 4 and is provided with parallel oppositely, extending cord receiving notches 7 and 8 on its opposite sides communcating with cut-away portions 9 and 10, shoulders 11 and 12 being provided thereon adapted to engage with the twine in the manner described therein. The cord holder plate is also provided with an upstanding annular wall- 13 having a cord-receiving notch 14: at one end thereof and a depression 15 at a point adjacent the knotter book, as well as a raised cord engaging portion 16 cooperating with the bottom of the disk to hold the twine. As in the construction described in that patent, the plate 1 is also provided with a side cut-away, as shown at 17, and relieved, as shown at 18, to permit the cord to be withdrawn by the needle. In our improved construction a lug 19 is extended from the plate 4 at a point adjacent the pivot 20 of the disk, this lug preferably being of the same height as the raised p01- tion .16 and provided with a vertical side wall 21 proj ecting outward beyond the cut away portion 17 and a vertical end wall :22

disposed at an angle of slightly over 90 to the wall 21, the other side wall 23 being inclined to wall 22, as shown, and extending backward therefrom to apoint over the axis of the disk.

In the operation of our improved'construction, it has been found that when the knotter -is threadedjasfshown inFigQl, the'leng'th properly threaded, our improved means acting to prevent any interference "of the efficient operation of the knotter'when-the latter'is improperly threaded, therebyenabling the device to be used by even the most unskilled operators without any difficulty being experienced. Thus from the farmeflsstandpoint time is saved,'and from the manufacfactures standpoint the time and "money incurred in furnishing experts to'correet the difliculties resulting from improper manipulation "by theoperator have also been saved. Obviously, the .constructionshown is also exceedin'glysimple andfiadapted to be applie'cbto a cord holderof the construction described at practically "no expense.

'rWhile we have 'in'this application specifically described "one embodiment which our invention'may assume in'practice, it is, of course, to 'be'unde'rstood that the construction may be modified without "departing from the-spirit of the inventi.on,- and that "it is our-intentionto-include allsuch modifications within the scope of the appended claims. 7

lVhat we claimas'our invention and desire to secure'by Letters Patent is 1 1.
