GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 332,986, dated December 22, 1885.

Application tiled October 28, 1884. Serial No. 146,652. (No model.)

To all whom it may concern:

Be it known that I, JOHN F. APPLEBY, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Grain-Binders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled-in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My present invention relates to improvements in that type of self-binders in which the tripping devices or means employed to throw the binder-driving mechanism into action on the sheaf binding and discharging mechanisms are operated from the packerarms or other devices which press the grain down into the gavel-collecting receptacle.

My invention has for its object to render the trip mechanism,which is actuated by the packer-arms, so sensitive at the given time to theresistance of the grain to the packer-arms, and so prompt in its movements as to make the tripper certain in its action, whereby wet or tangled grain or other causes are not liable to operate it too soon, and thus produce sheaves of too small size, and whereby other causes will not prevent its prompt action at the proper time, and thus produce too large sheaves,and bring unnecessary strain on the binding devices.

One type of binders to which my invention relates is shown in United States Letters Patent No. 264,602, issued to me September 18, 1882, and I have chosen parts of the binder shown and described in said Letters Patent for the purpose of illustrating my present invention, and said patent may be referred to for a fuller description of such parts as are shown and their operations fully described therein, and hence need not be further herein described than will be necessary to a ready comprehension of the nature and operation of my improvements in connection therewith.

In my former patent hereinbefore referred tothe sliding yoke which slides on the driveshaft of the binder mechanism is forcedaway shaped ends for the purpose will slide between the projections from the drive-wheel and said arms, and thereby yield with greater promptness and certainty to the resistance offered the packer-arms by the gavel when it (the gavel) has become of the size required and given by the adjustment of the binder mechanism in the well-known manner.

My invention further consists in improvements in the means used for transmitting motion from the sliding sleeve on the drive-shaft to the rock-shaft, which is designated by the reference-letter e2 in my aforesaid patent, all as hereinafter described.

In the accompanying drawings, Figure 1 A is a top plan of my invention and adjacent parts of a grain-binder. Fig. 2 is a front end elevation. Fig. 3 is a side elevation. Fig. 4 is a perspective lshowing the sprocket drivewheel and the clutching mechanism. Fig. 5 is an elevation of parts shown at Fig. 4. Fig. 6 is a top plan of my improvement, showing the parts in different relative positions from that shown at Fig. 5. Fig. 7 isaperspective of the sliding yoke.

In the several gnres of the drawings, and in order that the drawings may be fully understood, the same referenceletters are used to designate the same parts as in my patent No. 264,602, except the parts of my present invention, which are designated by reference-letters not used in said patent, and in which the same reference-letter designates the same part in all the figures where used.

D is the main driving-shaft of the binder mechanism, and is continuously rotated while .the machine is in operation by a chain passed around the sprocket-wheel E and around a driving sprocket-wheel mounted on a main shaft (not shown) of the harvester. The sprocket-wheel E is loosely mounted on the shaft D, and is connected with said shaftD so as to rotate it, as hereinafter described. The shaft D is provided with cranks G G, which IOO operate the packers B B in the ordinary manner. The shaft D, with its cranks G and wheel E, is operated as shown and described in my aforesaid patent, as is also thetrip lever or arm a., which has to be slightly lifted atits upper or free end in order to liberate the spring-dog b, that rests on the said end of said lever a, for the purpose of clutching the driveA pi-nion ofshaft D, which is normally loose on the shaft that operates the devices for binding and tying and discharging the sheaf.

I? is a yoke, mounted on the shaft D and made to rotate therewith, while it can slide lengthwise of said shaft by means of a feather, p', which projects from the hub of the yoke into a groove, t, inthe sha-ft D. The arms of the yoke P extend radially from the shaft D, and their ends 1J are bent and are parallel or about parallel with the axis of said shaft, and are tapering or wedge shaped, as shown. Lugs 1)12 project one from each radial arm of the clutch P,being one at each side of the shaft- D. The yoke P is pressed or forced toward the wheel E by a strong spiral spring, m, which encircles the shaft D, and the yoke is forced in the opposite direction by the mechanism now to be described.

From the face of the wheel E which is foward the yoke P project two studs, l, located at diametricallyopposite points on said wheel, and each provided at its outer end with axial bearings for an anti-friction roller, 2.

R R are arms projecting from the shaft D between the wheel E and the radial arm of yoke P. I have shown the arms R as connected and iiXed rigidly to the shaft D by means of a feather, r, and groove, as seen at Fig. 7; but they may be rigidly connected with said shaft in any desired manner. The end of each arm It is bent toward the wheel E and provided with an axial bearing for an antifriction roller, r. The anti-friction rollers r are in or about in the same circumferential plane with reference to the shaft D as are the similar' rollers 2.

While the yoke P is in its normal position or pressed toward the wheel E by the spring m its wedgeshaped ends p rest one between each of the rollers 2 and r', and the other between t-he other rollers 2 and o", as shown most plainly at Figs. 5 and 6.

In describing the operation of my present invention it is not deemed necessary to describe the operation of the packers or other parts of the binder.

The continuous rotation of the wheel E will continuously rotate 'the shaft D by means of the rollers 2, acting on the wedge-shaped ends 19 of the yoke P, and when the grain in the grain-receptacle has increased to the given quantity necessary to offer a given resistance to the forward movement ofthe points of the packers it will tend to retard the shaft and also the yoke P revolving therewith, and thereby cause the roller 2 to force the wedgeshaped ends p of the yoke P with increased force against the roller r', and thus cause the yoke P to yield lengthwise of the shaft, as shown by dotted lines at Fig. l,and thereby bring one or the other of the lugs Win-contact with the arm d', which is rigidy connected with and projects radi-ally from the rock-shaft e2, and by its action on said arm partially rotate said shaft e2, and thereby operate the trip.- lever ci and the devices for binding, tying, and discharging the sheaf, as shown and described in my patent hereinbefore referred to. As soon as the sheaf is discharged the resistance to the packers ceases, and the spring m will force the yoke P back toward the wheel to the position shown by full lines in the drawings. There being no connection between the yoke P and the arm d, and the yoke being geared with the wheel E, as it is, will move out of contact with the arm d' promptly when the'.

resistance of the grain to the packers ceases, and the yoke will move into contactwith said arm when the proper resistance of the grain to the packers is reached, promptly, and thus form sheaves of uniform size, and resist strains and interference with regularity of binding by wet or tangled grain and from other causes.

All subject-matter shown in the drawings and described in this specification not perf taining to the particular tripping device herein claimed is hereby disclaimed in this application.

It will be readily seen that one arm of the yoke P may be dispensed with, and also the adjacent arm R, and the adjacent stud l and its roller 2; but I prefer to use the device with YIco all of these parts, as shown and described; and l I do not limit my claims to the use of the twothrowing the binding, tying, and sheafdischarging mechanism into operation, in combination with a loose sprocketwheel, E, the constantly-revolving shaft D, and the packers, a sliding yoke, P, on shaft D provided with wedge-shaped ends arranged to stand between projections from the wheel E and arms fixed to the shaft D and provided with lugs p, an arm projecting from the shaft e2, and a spring adapted to force said yoke away from the arm on the shaft e2, substantially as and for the purpose specified.

2. In a grain-binder of the type herein described, in combination, the shaft. D, carrying the packers, a wheel, E, having lugs l,

and lugs p, adapted to coaet with the arm d on the shaft e, and a spring, m, substantially as and for the purpose specified.

3. In a grainbinder of the type herein ,I

specified, in combination with the sprocket wheel, E, loosely mounted on the shaft D,and i the arms R, fixed to the shaft D, a sliding] yoke, P, having tapering or Wedge -shaped arms adapted to coact with the Wheel E and fixed arms R, substantially. as and for the purpose specified.

4. In a grain binder of the type herein specified, in combination, the shaft D, carrying the packers, Wheel E, having vprojections l, and sliding yoke P, adapted to coact with a projection from the shaft e2, substantially as and for the purpose specified.

5. In a grain binder of the type herein specified, the combination ofthe shaft D, packers G,and a sprocket-wheel, E,loosely mounted on the shaft D, and adapted to act on one side of the Wedge-shaped armsp of the yoke P, and press their other sides against projections from the shaft D, whereby the yoke will be forced away from the wheel to cause it to engage With a projection from the shaft e?, substantially as and for the purpose specified.

6. In a grain binder of the type herein specified, the combination, with the packing arm or arms and the trip-lever, of an intermediate mechanism for causing the said arm or arms to actuate the said lever, composed, essentially, of a drive-Wheel mounted loosely on the drive-shaft of said packing arm or arms, a sliding` yoke mounted to slide on said shaft and held in close relation with the said Wheel by a spring and provided with Wedge-shaped or tapering arms adapted to coact with said Wheel, and arms projecting from said drive-y shaft and provided also with projections adapted when the yoke is shifted to communicate motion to the trip lever, substantially as and for the purpose specitiedn JOHN F. APPLEBY.
