Patented Nov. 3, 1942 UNITED STATES PATENT oFFIcE I BALE TYING TABLE 1 George Lamb, Hoquiam, Wash. e t Application February 17, 1941, seria1 No. 379,363

" .2 Olaims.- (01. 100-31) This invention relates to improvementsin bale tying tables, and has reference more particularly to tables of that type on which bales of pulp, or the like, are placedforbaling by use of wire bands.

It will be stated as explanatory to the present invention, that for many years it has been a common practice to locate the assembled sheets of pulp for baling upon a flat table top that is equipped with transverse and longitudinal channels, open throughout their lengths 'to theftop surface of the table, and through which the baling wires are projected under the material after it has been placed on the table. Such tables, with the open channels, have certain disadvantages, the principal one of which is that in the projecting or passing of a wire along 'a channel beneath the bale of material; its forward endis apt to and does frequently catch in the bale material, and to release it, it must 'be' withdrawn, turned over or twisted about. This difficulty has, in many. places, led to the substitution of longitudinally slotted tubes for the table top channels, and to the use of wire bands, each of which, at one end, is equipped with a helical coil of a diameter somewhat smaller than the inside diameter-of the tube so. that it can be passed therethrough without difiiculty, and which will retain the wire against passinginto the slot and catching on the bale during the operation of projecting it through the tubes After the coiled end portionof the'band has guided the end of the wire completely through the tube, then the band may be drawn upwardly, through the tube slot and secured about the bale.

While this use of wire bands with thepigtail end has solved the problem of the wire catching on the bale while being projected through the tube, it has disclosed an inherent disadvantage that is due to the character of the tubewhen equipped with the narrow longitudinal slot for the passage of the wire band when it is finally drawn upwardly and tightened about the bale. It will be understood that with the use of a wire guide tube of approximately one-half inch inside diameter, or larger, and equipped with a longitudinal slot approximately three-sixteenths of an inch in width, the wire band, in being drawn up tight about the bale, will very frequently catch on, or hang up on the tube wall by reason of not passing fully into the slot, and this hanging up of the wire can not always be detected before the ends of the wire are united. This undesirable result is not only very annoytime and effort and the inconvenience'that was incident to releasing the-band for detachment fromthe tube. H V

- In view of thefaboverecited-difiiculties that have been experienced in tying tables as here having longitudinal slots so formed and shaped that there is no possibility of the tie'wire being. retained or caught in the tube incident to the threading or baling operation;

More specifically stated, the objects of the present invention are-to be found in the provision of a tying table with'wire guide tubes arranged'inthetopthereof for the passage of the baling wires beneath the bales and which tubes 7 are each equipped with a longitudinal open slot along the top edge,- to-which slot the side walls of .the tube gradually converge in straight lines rather than in'a curve as in the prior use of the tube; these opposite side walls, which lead to the longitudinal slot, extending tangentially from the opposite sides of the tube at an angle of approximately 60 to each other. I

Other objects of the invention'reside in the details of construction and combination of parts as will hereinafter be fully described. I

Inaccomplishing these and other objects of the invention, I have provided the improved details of construction, the preferred forms of which are illustrated in the accompanying drawing,

- wherein- Fig. 1 is aside view of. a tying table embodying the present invention.

Fig. 2 is'a top view of'theitable.

legs 2 which, at their lower ends, are attached ing, but is also the cause of delays, waste of 55 to an anchored base structure 3. The table might be of the stationary type, or it might be of the turn table type. However, that is not of consequence to use of the present improvement.

Mounted on the table top, transversely thereon and in parallel relationship, are conveyor rolls for the support of the bales during the tying operation and for easy conveyance of the bales onto and from the table. Also, arranged transversely of the table top, at spaced intervals, are wire guide tubes 6, here shown to be three in number, and extending lengthwise of the table are two wire guide tubes, designated by reference numerals 6 which are like the transverse tubes 6, but are made in alined sections, spaced apart at their ends as required for the accommodation of the transverse tubes, as is noted in Fig. 2.

As will be understood by reference to Fig. 2, the transverse tubes 6 are continuous, and are supported at their opposite ends between the vertical flanges of angle iron rails I which are fixed along opposite side edges of the table top and mount the outer ends of certain of the rolls 5 therein. These vertical flanges of the angle iron rails are formed with openings, as designated at8, in Fig. 1, whichregister with the ends of the wireguide tubes 6, and there are slots 9 leadingupwardly from the openings 8 to the top edges of the flanges for the passage of the wire bands, as will be presently understood, The longitudinally extending wire guide tubes 6 are supported, as illustrated in Fig. 3, by means of legs or brackets I0 which are afiixed at their lower ends to the table top.

Each of the tubes ,6 and 6' is of cylindrical n I2, in this instance, is made only of such width as required for the passage of the-Wire band therethrough when it is drawn about the bale. Preferably, the base portion of the tube is circularly curved and the'side walls wand 61) are flat and continue in planes that are tangential to the cylindrical body.

The

tubes

6 and 6 as used in the table, are

supported rigidly somewhat below the plane of u the top surface of the rolls 5, and the slots I2 all opendirectly upwardly-and each tube is open at both ends. 5

The wire bands which are to be employed preferably are of the kind shown in Fig. 5; wherein the wire 26 is shown as being equipped at one end with a helical coil 2| that is formed by bending an end portion of the band back upon itself and wrapping it spirally along the length of wire as shown. This'leaves a rounded end loop 22 at the forward end of the'band, which facilitates passing the wire through the guide tube. The helical coil' is of such'diameter that it cannot pass through the slot I 2.

In use of the present table, equipped with the tubes 8 and 6' as described, it will be understood that the material to be baled can be moved onto the table top and there supported upon the rolls 5 for the baling operation. The wire bands 20 which are to be employed in baling are projected lengthwise, with the helically coiled end forward, through the various tubes 6 and 6' and their opposite end portions then drawn upwardly along the sides and across the top of the bale, then about the bale and the ends secured together. When the wire bands are projected through the tubes, the helical coils prevent the advancing ends from passing into the slots I2 of the tube. Thus there is no possibility of the band catching on the bale material prior to the advanced end of the wire leaving the tube. After a band has been projected through a tube, it will be understood that when it is tightened, the inclined opposite side walls 6a and 6b of the tube will guide that length of the wire that is in the tube, directly to the's'lot I2 and-there will be no possibility of its being caught or retained in any way by the edge portions of the tube adjacent the slot.

It is not the intent that the present claims shall restrict the invention in any way insofar as the character or use of the table is concerned, or that it shall be; restricted by use only in tables in whichthe supporting rolls for the bale are incorporated; it being intended that the claims shall apply-broadly to the use of tubes of the present character: whether used in the specific structure heretofore set'forth, or otherwise, so long as it is for the guiding of a wire of the present kind-beneath a bale or package to facilitate the binding operation.

Having thus described my invention, what I claim as new therein and desire to secure by Letters Patent is:

1. In a bale table of. the character described, a table top equipped for the support of material to be baled, and a plurality of longitudinal and transverse tubes mounted in the table top and crossing each other at different levels, and open at their opposite ends; each for the passing of a wire band therethrough, and each having an open slot extending along the top side thereof from end to-endwith the 'tube walls at opposite sides of "the slot converging gradually along straight lines toward theslot; the upper tubes being transversely divided and the divisions thereof slightly'spaced, providing vertical. passages that are alined with the slot of the corresponding lower tubes;

2. A baling table asset forth in claim 1 wherein spaced horizontal rollers are mounted transversely' on the table-for the support of a bale thereon, and said transverse wire guide tubes are disposed intermediate said rolls and said longitudinal tubes are disposed beyond the end limits of the rolls.
