Application October 19, 1942, Serial No. 462,660

1 Claim. (01. 56-480) This invention relates to improvement in means for lifting the bundle carriers of tractor binders and more especially binders of the Deere type. These carriers have been provided with lifting means but the means are so constructed that, when the carrier has been raised to the upper limit of its movement, it has been supported in the path of portions of the packer mechanism with the result that a pounding action has been set up which has soon worn down or broken some of th parts and necessitated replacements.

The present invention has for its object to provide a lifting means so shaped and proportioned as not to interfere with the operation of a packer when the bundle carrier is in raised position, it being possible to accurately adjust the parts to insure free operation without interference.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a side elevation of that portion of the'bundle carrier lifting means constituting the present invention, its relation to one of the packers when the carrier is raised its maximum distance, being indicated.

Figure 2 is a plan view of some of the structure shown in Fig. 1.

Figure 3 is a front elevation of the parts constituting the present invention, other parts adjacent thereto being shown partly in section and partly in elevation.

Figure 4 is an enlarged section through the bundle carrier stop.

Figure 5 is a similar view showing a modified construction of the stop.

Referring to the figures by characters of reference, I and 2 designate superposed side portions of the binder, the upper member 2 having one or more hangers 3 suspended therefrom and supporting packers one of which has been indicated at 4. These packers are adapted to be actuated by a crank shaft 5 driven by a suitable mechanism provided for that purpose, the cranks being connected to the packers in the usual way and operated by the usual or any preferred mechanism.

The parts thu far described are not in themselves a part of the present invention but can be found in a binder of the type heretofore mentioned. In the said binder the bundle carrier, which has been shown in part at 6 in the accompanying drawings is carried by a shaft i having a crank 8 at one end which is mounted for back and forth rotation in the tubular portion 9 of a casting which is fixedly joined to the member I and has an upstanding portion is reenforced by means of braces H and i2.

Shaft 1, which is comparatively short, is extended into and constitutes a bearing for one end of a tubular shaft !3 formin a part of the bundle carrier 6 and fixedly secured on that end of the tubular shaft l3 nearest the crank 8 is a collar [4 having an integral saddle l5 extending forwardly therefrom and laterally so as to pass beneath and transversely of the crank 8. This saddle is formed with a stop for limiting the relative movement of the crank and saddle. As shown in Figs. 2, 3 and 4, the stop can be in the form of a screw l6 provided with a lock nut I! but, under certain conditions, it would be more advisable to provide a stop block I8 on the saddle which is welded thereto as shown in Fig. 5.

Back of the saddle I5 the sleeve 14 is formed with a lateral extension l9 which embraces the rear portion of the crank and has an upwardly extending ear 20 formed with an opening 2|. This opening is adapted to receive the hooked lower end 2| of a connecting link 22 the upper end of which is screw-threaded as shown at 23 and is extended through an eye 24 at one end of a pin 25. Nuts 26 engage the screw-threaded portion 23 of link 22 and are positioned above and below the eye 24 so as to hold these parts assembled adjustably.

Pin 25 is extended transversely through the rearwardly extended arm 27 of a lifting crank 28 which, as shown particularly in Fig. 1, is substantially Y-shaped with a downwardly and forwardly extended arm 29 and an upwardly and forwardly extended arm 30. The lower end of arm 29 is extended into the casting l0 and pivotally connected thereto by a pin 3i while the upper end of arm 30 is pivotally engaged by a connecting rod 32 adapted to be actuated for the purpose of raising or lowering the bundle carrier.

An important feature of the present invention resides in the fact that the parts 22 and 28 are so proportioned and located that they will not move into the path of the packer 4 when the bundle carrier is in either raised or lowered position. In other words when the crank arm 21 is swung upwardly by a pull through rod 32, it will actuate link 22 to pull upwardly on the collar I4 until the stop carried by saddle l5 comes against the crank 8 in the path thereof.

When the crank 28 reaches the upper limit of its movement which is determined by its contact with the casting ID in which it is mounted, the arm 21 of the crank is below the path of the packer 4 and its hanger 3 but, because of the comparatively short length of the link 22 and the provision of the stop on the saddle IS, the carrier, when lifted by this movement of crank 28 will be properly elevated to support and carry the bundle. When it is desired to dump the carrier, the operation is reversed, motion being transmitted from rod 32 to arm 30 so as to permit downward movement of arm 21 or else the rod 32 can be released and the arm 21 can swing downwardly under the weight of the load subjected to it. This swinging action will of course allow the crank 8 to swing downwardly, thereby lowering the carrier and at the same time permitting the carrier to tilt downwardly and backwardly to release its load. This movement will not be sufiicient to bring the arm 30 into the path of the hanger 3 and the packer 4.

As has heretofore been pointed out, when a carrier has been raised by means of the mechanism provided for that purpose, the member which is being displaced by the crank 28, has been brought into the path of one of the packers with the result that a. pounding has been set up which has interfered with the efiiciency of the machine and has caused it to wear or break. It has been found that by shortening the link 22 and providing a stop on the saddle I5 whereby the extent of movement can be controlled, the objectionable features heretofore present and herein referred to are completely eliminated.

What is claimed is:

The combination with a binder, a crank mounted to swing on one side portion thereof and extended laterally therefrom, a laterally extended shaft movable with the crank and a packer mounted for lateral movement transversely of and above the crank, of a carrier including a tubular member rotatably mounted on said shaft, a collar rotatable with the tubular member, a saddle extending from the collar and under the crank, an adjustable stop on the saddle for engagement with the crank to limit the relative movement of the crank and saddle, a substantially Y-shaped member having forwardly extended upper and lower arms and a rearwardly extended arm, said lower arm being pivotally mounted on the binder, operating means connected to the upper arm, the rearwardly extended arm being positioned at all times below the path of movement of the packer, and an adjustable link connection between the rearwardly extend ed arm and the collar, said link connection including a threaded member having a hook engaging a portion of the collar, a swivel pin mounted in the rearwardly extended arm, said pin having an eye, and means on the threaded member for holding it adjustably to the eye.
