SPECIFICATIO-Norming part of Letters Patent No. 352,091, dated November 2, 1.886.
Application tiled March 1., 1886.
To all whom it may concern:
Be itknown that I, HOMER. JOHNSTON, a citizen of the United States, residing at Batavia, in the county of Genesee and State ofkNew York, have invented a new and useful Improvement in Grain-Binders, of which the following is a specification.
My invention relates to improvements in grain-binders in which the grain is automaticv ally bound through the instrumentalities commonly used in the well-known type of the VAppleby binder; and the object of my improvement is to provide an arrangement where-V by the usual tripping-lever shall be securely fastened at the conclusion of the binding operation, and prevent the knotter from repeating, or making these'cond vibration incident to the rebound of the lockinglever. I attain this object by the mechanism' illustrated in the accompanying drawings, in'which Figure l is a plan view of so much of the gear-train of a binder as is necessary to illustrate myinvention, showing the -tripping-lever in contact with the spring locking-pawl, and with thestay-lock in operative position, the relative situation of the parts4 when the tripping-lever is approaching the locking -pawl being shown in dotted lines. Fig. 2 is a like view of a modicatio-n, and Fig. 3 is a frontelevation of Fig. 1. Similar letters refer tosi lnilar parts th roughout the several views.
As the invention relates entirely tothe supplementary lock, this with its immediate consaid gear-wheel, while the reverse side .of`
wheel A2 meshes into and drives the intermediate wheel, A', which in turn drives gearwheel A. l
C is the tripping lever having at its axial end an arm, C', rising diagonally from the upy Serial No. 193,668. (No model.)
.per side thereof, which, when the mechanism is locked, abuts against the studc, projecting from the face of the intermediate wheel,` A.
D is a crank-arm mounted upon shaft B and carrying upon its free end the wrist-pin d, by which,` in conjunction with the connecting-rod d and wrist-pin d2 upon the face of gear-wheel A, the'said gear-wheel and crank-arm are pivotally united, for a purpose hereinafter described. f
Rising from arm D is a rearwardly-curved rod, e, which passes through the flange c2, projeciing laterally from the arm C, and about which is coiled the spiral spring e', the lower end of which rests upon the face of ange c2, the other abutting against the nut e, mounted upon the free end of the rod e. t This spring is for the purposeof keeping the lever C down AsslreNOE rO THE JOHNSTON.-
toits work and retaining it in vertical line fingers, which are operated in the usual and well-known manner, but are not herein shown. In practical operation the grain is automatically packed in the binding-receptacle', and when a sufcient quantity is gathered therein to work the trip the tripping-lever Gis (through the necessary mechanism) raised, which disengages it from the spring-dog F, the heel of which, immediately upon its release, is caught ,by the revolving head E', andV by this means t-he train of gearing is set in motion and-with it the entire binding mechanism, so that by the time the gear-wheel A has made one entire revolution the gavel has been bound and the sheaf discharged from the machine. By this one revolution of the large gear-wheel the tripping lever C, by the connecting rod, is made to rock backward and return again, so as to lock the gear-train and hold it until a succeeding gavel shall be formed, when the operation is repeated.
rIhe above-described operation is common as applied to the Appleby type of machine.
When the lever Gis brought forward and in f t t position for locking the binding mechanism by its engagement with the spring-dog F, the movement is quite rapid, yand as the dog during this descent is revolving with celerity the concussion is so great that in striking the lever C it will cause it to rebound, so that the binding operation is repeated, and by so doing the discharged grain is scattered upon the ground in an unbound condition. To obviate this result I have placed upon lever C the upright arm C', which, when the lever is in position to catch the revolving dog, abuts against the stud c upon the Wheel A, (or Wheel A2,) thus keeping the lever down and making a positive lock, so as to prevent a repetition of the knetter movement until the mechanism is again tripped by the packing of the grain, as hereinbefore described.
The modification shown in Fig. 2 is the same as that seen in Fig. l, except that the stud therein shown, and designated c', is made more lug shape and placed upon ywheel A2 instead of Wheel A', and against which the arm'abuts.
Having new described my invention, what I claim as new, and desire to secure by Letters Patent, is-
' 1. The combination, with the binder-driving train and the drivingshaft of the binder provided with the usual clutch, of the trip-lever, the arm O,formed thereon, and the stud formed 3o on one of the intermediate gear-wheels of the train, all arranged substantially as described, whereby-the said arm and stud will come into engagement just before the engagement of the trip-lever and elutchdog, substantially as set 3 5 forth.
2. The combination, with the automatic binding mechanism of a harvester, of the arm C', the tripping-lever C, and the stop c upon the Wheel A2, for the purpose of locking the 4o binding mechanism out of engagement, substantially as described.
