BOX-SHOOK-BUNDLING MACHINE.

Specification of Letters Patent.

Patented Mar. 8, 1921.

Application filed July 6, 1920. Serial No. 394,318.

To all whom it may concern:

Be it known that we, S UIRE J. JoHNsoN and GEORGE 00D, citizens of the United States of America, and residents of the city of Seattle, in the county of King and State of WV-ashington, have invented certain new and useful Improvements in Box-Shook- Bundling Machines, ofwhich the following is a specification.

Our invention relates to improvements in vide a machine of the kind described which will be reliable'and convenient in operation.

Our invention comprises those parts and combinations thereof which are shown in the accompanying drawings, described in the specification, and particularly defined in the claims terminating the same.

In the accompanying drawings we have shown our invention in a form which is now preferred by us.

Figure 1 is a perspective with parts broken away, illustrating our machine in operation, and looking at it from the loadin side.

ig. 2 is an axial section through the lower portion of our machine.

Fig. 3 is a section on line 33 of Fig. 2.

In bundling box shooks there are ordinarily three operations which must be performed upon each bundle, after the preliminary operation; of piling the shooks. The bundle, after it is formed, must have a wire placed about each end of it and a wire must then be placed across the two preceding wires and lengthwise around the bundle. These operations should be performed while the bundle is held in a clamp and before it is removed-from the machine upon which it is piled as it comes from the shook forming machine. .Moreover, each operation, piling, and the three tying operations, consume practically an equal amount of time for each.

In order to save time and to promote the highest efficiency, we provide a bundling machine formed of four piling heads or himdle supports, which is rotatable about a central axis so that each operation may be performed progressively by different operators. Thus each step is in progress at the same time upon different bundles.

The bundles are piled upon lateral supporting arms 1. These project radially from the central pivot post 2 and should preferably be equally spaced thereabout. Each lateral supporting arm 1 may be composed of two beams, if desired, which are slightly spaced. The space between them we prefer' to bridge by the plate 10. The supporting arms 1 are preferably slightly slantedto incline the bundle toward the central axis of the machine.

Upright supports 3 are connected to each of the lateral arms 1 and extend upward until theyare joined, as by a spider 31, at their upper ends, where they have a pivotal support in the upper end of the pivot post 2. These uprights are preferably formed of two spaced beams, between which are placed the operating parts to be hereinafter described.

The lateral supports 1 are all secured upon a flange 21 of a sleeve 20 which is rotatable upon the pivot post 2. At its lower end the pivot post 2 may be secured in afloor flange 22. Near the lower end of the sleeve 20 we provide a series of pivot pins 23 for a purpose to be later described. 7

Associated with and movable upon the upright supports 3 are the bundle clamping arms 4. These are guided upon the uprights 3 by fingers 40, as shown in Fig. 1.

A treadle bar 5 is pivoted at its inner end upon one of the pins 23. which are formed in the sleeve 20. The clamping bar4 and the treadle 5 are connected by a suitable link 41, positioned between the two upright beams. Ive prefer to form the link with a series of holes 42 therein, these holes being adapted to fit upon a pin 43 formed in the clamping bar 4, thus permitting relative adjustment between the link 41 and the clamping bar 4. A similar connection may be made between the treadle 5 and the link 41. A spring 6, positioned between the upright beams of the support 3, and connected at one end to the treadle, at 56, and at its surface of the upright support 3.

tion for the lower end of the link 41 and the treadle. Either or both of these connections should be such that the'link and the spring lie inside of the outwardly-facing This causes the point 56 to be located near the sleeve 20, and to provide a longer leverage treadle bar 5 we prefer that its inner end be offset as shown at 50 and pivoted to the pin 23 at the side-of the sleeve. It is very desirable that the treadle project radially .from the sleeve, as the link 41 and the spring 6 are'positioned between two spaced uprights 3 of each pair.

As the plate 10 bridges the space'between the two lateral arms lof each pair, there is no chance for the end of a bundle or the end'of the lower shook of the bundle being pressed downwardly into this space by the pressure of the clamp. This might occur if the plate were not so placed, and a bundle of short shocks were being tied. The presence of the plate 10 also prevents an unskilled operator from attempting to tie a wire about the central portion of the bundle of shocks between the two spaced lateral beams. We prefer to cut away a small portion of the plate 10, as shown at 11, to permit the operator to glance through the gap in using the treadle to clamp or to release. This permits the operator to glance down without moving back from the machine and in this manner saves time and effort.

A method of using the machine may be as follows. Shooks sufficient to make a bundle are piled'upon one set of arms 1 and uprights '3. WVhen a bundle is completely assembled it is clamped in. place and the machine rotated to bring the next set of arms in position. At the first tying station, another operator places a wire about one end of the bundle. At the next station another operator places a wire about the other end of the bundle before shifting it and then, if it is desired to use a cross wire, the bundle is given a quarterturn and thefourth operator places the cross wire in place. The method of use is, however, determined by the character and number of wires required.

The last operator would release the bundle and remove it from the machine and this head would then be free for piling the next bundle thereupon.

It will be noted that each bundle clamp is a unitindependent from. all of the other units in the machine. A bundle may be tied, released, shifted, or removed entirely from the machine without disturbing the remainindependent heads, as this would make it suitable for all ordinary operations. At the same time less than four heads may be used if no more are required.

What we claim as our invention is: r
