and the novel 4features thereof defined by the y This invention relates to a method of and apparatus for bundling flooring, the oblect being to provide an apparatus for carrying out the method of bundling strips of flooring in such a manner that the flooring will be bundled without injuring the same, the apparatus being especially adapted for use m bundling iiooring which has been finished.

Another object of the invention is to provide means for binding the bundle after it has beenformed so as to hold the strips between a air of supportsin such a manner that all anger of the strips moving on one another is prevented.

Another and further object of the invention is to provide an apparatus having a support to receive the bundle of floorin in connection with a scale, by means of w ich the feet of flooring in the bundle will be indicated to the operator so that he can designate on the bundle the feet the bundle contains.

A further object of the invention is to provide novel means for forming the bundle wherein the strips of ilooring are nested and supported by spacing members in the -form of strips so that when the binding bands are placed around the bundle, the strips will be flexed slightly in order to hold the same under tension within the supporting members whereby a bundle is formed which will prevent the strips from moving in respect to one another thereby overcoming the danger of marring the finished faces of the strips.

Another and further object of the invention is to provide a pulling device-for the metal band used for binding the strips within the bundle which is operated by afoot treadle and so mounted that the mechanism will grip the band in one of its movements and travel free of the band in its other movement whereby the operator by repeating the operation can apply the proper tension to the band surrounding the bundle.

Another and further object of the invention is to provide novel means for fastening the ends of the band on one of the supports forthe strips.

Other and further objects and advantages v of the invention will be hereinafter set forth applied on the treadle it will be drawn tightly aroundthe bundle, the movable sto being shown thrown out of the path o the bundle through the apparatus;

Figure 3 is a side elevation portion of the i apparatus;

`Figure 4 is a perspective view of a bundle formed in the apparatus;

Figure 5 is a transverse section through the same;

Figure 6 is a detail view of a portion of a bundle showing the first fastening means for the band arranged in position;

Figure 7 is a plan view of a portion of the scale used for indicating the surface feet when flooring strip two inches wide is being bundled; Figure 8,is a similar view of a scale for indicating the surface feet within the bundle when one andl one-half inch wide strips of floorlng are being bundled; and

Figure 9 is a detailed view of the lever placed around the same. The rollers 2 andv 3 constitute what might be termed a form in 5 bundle as it is moved from off the supportl by the operator. A binding device is arranged in advance of thestationary suport 4 for binding the bundle with a metal band after it has been formed. The binding device comprises a suitable support 5 having i inner end which is adapted to cooperate withstandards 6 in which is mounted a vertical lever 7 so disposed Vthat it engages the side of the bundle thus formed and carries at its free end alink 8 which supports an arm- 9 having notches 10 to receive the trunnions of a reel 11 adapted to contain a metal band 12 in the form of a ribbon which is used as a binder for the bundle but it is of course understood that I do not wish. to limit myself to the use of a metal band as I am aware that a wire could be used without departing .from the spirit of my invention.

The arm 9 is provided with a jaw 13 at its a jaw 15 formed on an extension 14 of the lever 7. The ribbon is adapted to pass between the

jaws

13 and 15 so that it can be placed around the bundle and placed under tension by the jaws as will be later described.,

The lever 7 is provided with a weighted angled end 16 to which is ivotally connectedl a foot treadle 17 having an adjustable connection 18 with the arm 9 in the form of an adjustable link. The treadle is connected to the lever by a coil spring 19 which holds the/upper end of the lever against the side of the bundle and returns the treadle to its normal position after being depressed by the operator.

The ribbon band 12 which passes between the

jaws

13 and 15 travels in the path of a shearing knife 20 to enable the band to be severed at any time by the operator, said knife being pivotall mounted and provided with a handle 21 or operating the same. The extension 14 of the lever 7 is in the form of a handle which can be gripped by the operator so as to return the lever 7 to its normal position and to enable the operator to force the same against the side of the bundle.

The extension 14 of the l'ever is provided with an overhanging portion 21 which when in the position shown in Figure 2 extends over the bundle for preventing the bundle from moving vertically and forms a guide so that if he iiooring strips are warped or l sprung in any way which would raise the upper support the upward movement thereof,

would be limited. The ribbon being drawn through the gripping jaws by the operator and passed around the bundle and by exerting a downward pressure on the treadle, the

lever away from the bundle so as to apply the proper tension to the metal band around lthe same and by releasing the treadle the lever 7 is returned so that the operator can press the treadle again so as to apply tension to the band and in practice the treadle-is pressed two or three times so that the band is drawn tightly around the bundle.

' Mounted in a suitable bearing formed in the lever y7 is a bolt or shaft 22 on which is mounted an eccentric hub 23having a lever 23 formed inte ral therewith, the inner face thereof being eveled and adapted to be drawn up along side of the bundle by the operator to force the strips against the lever 7 so as tocompress the bundle.

The lever 23 is provided with a handle 22 vwhich can be gripped by the operator for manipulating the same. When the lever 23 is in the position shown in Figure 3 the bundle is capable of movin freely on the support so as to position t e' same in the binding device.

The hub 23 is held against the lever by coil spring 232, the tension of which is adjusted by nuts 233. After the bundle has been positioned within the binding device, the operator raises the lever 23 which .brings the beveled or inclined face against the side o f the bundle and forces the bundle against the lever 7 so as to compress the same before the band is placed in position. The upward movement of the lever 23 brings the eccentric hub 23 against the bottom support of the bundle in order to provide a rigid support which enables the bundle to be held vfirmly while the band is being secured around the same.

Arranged in advance of the binding device is, a pivoted stop member 24 mounted on shaft 25 arranged in bearings 26 formed on the base 5 against which the end of the bundle is adapted to be forced, said movable stop being capable of moving into and out of the path of travel of the bundle. As thebundle is moved forwardly the ends of the strips and supports` forming the bundle engage this movable support so as to aline the ends and the lever 23 is then swung upwardly so as to compress the bundle and hold the same while the metal band is being placed in position thereon.

After a band has been placed around the bundle the bundle is moved forwardly, it of course being understood that the movable stop is moved Vout of the path of travel of the bundle until the end is placed on what I have termed a receiving table 27 which is provided with horizontally disposed rollers 28 and vertically disposed rollers 29. Arranged above the receiving table is a scale 30 which is graduated so as to indicate the surface feet within the bundle and the scale eillustrated will indicate the surface feet Within a bundle formedof strips of flooring 2 inches When stripe4 of ooring an inch and a half wide are ing bundled, a scale 31 is substituted-forl thel in order to prevent the strips from crushing under pressure and to allow the strips to flex when placed under pressure by the band.

The spacing strips are ofsubstantially the same height as the distance between the upper and lower supports and are placed in position before the upper support is placed over the iooring strips which prevents these strips from turning. i

The flooring str1 s are secured between the supports 32 an 33 by' bands of', metal 36 whlch is first placed around the bundle with its ends terminating midway of the upper support. The metal band is then drawn tight around the bundle thus formed by pressing down onthe treadle of the apparatus and the operator repeats this operationl one or more times so that the proper tension will be applied to the bands in order to hold the strips of iiooring securely without any danger of the strips moving when being shipped.

With his foot on the treadle and the band under tension the operator takes a dual punch and punches holes through the overlapping portions of the band and drives a staple 37 through these openings. The band is then severed by the shearing device 2O and the free end 36 is bent back upon itself over` the staple 37 and secured by staple 38 arranged at right angles to the staple 37 which forms novel means for'securing the end of the band in position around the bundle. l

The method of forming la bundle of iiooringl on an apparatus illustrated is as follows z-A support is laid upon the delivery table 1 on the rollers 2 and between the rollers 3' constituting the form and the strips of liooring are nested together on the bottom support. The spacing strips are then placed in position and the upper support laid on the upper edges of the. flooring strips.

The bundle thus formed is then moved forwardly over the stationary support until the end of the same engages the movable stop which has been swung in the path of travel of the bundle. The operator Vthen swings the lever 23 upwardly which brings the beveledface of the same into contact with the side of the bundle so as to place it under com ression and to force the strips together. TEe upward movement of the lever brings the eccentric hub into engagement with the `bottom support of the bundle. He then operates the bindingdevice, it of course being understood that the" bundle has been moved :in position so that the band will be' placed at the desired point. When the bundle is moved forwardly with the stop in the path of travel of the same, the ends of the` supports and flooring strips are brought into alignment so thatwhen the lever 23 ismoved upwardly the bundle will be placed under compression to enable the metal band to be placed around the same. l

The operator then takes hold of the freeend of theribbon or metal band and draws the same around the bundle thus formed, allowing the end of the band to terminate substantially midway of the upper support of the bundle. The spacing strips disposed between the supporting strips of the bundle are so disposed that they are never at the point or in transverse alignment with the ands placed around the bundle.

The operator then presses down on the treadle and the band is gripped by the gripping jaws on the initial movement thereof. the `final movement swinging the gripping jaws away from the bundle so as. to apply the proper tension to the band and by repeating this operation the required` number of times thevband is placed under the proper tension so as to securely bind the strips be- 'tween the supports.

The operator then talzes a dual punch and punches holes in the overlapping portions of the band and drives a staple into the open# ings in the upper support. He then severs the band by a shearing device and bends the free end back upon itself and secures the same by a staple which is arranged at right angles yto the staple already inserted, which latter/staple straddles the joint thus formed.

The movable stop is then swung out of the path of travel of the bundle and thc bundle moved the proper distance and another band is placed in position ina similar manner which operation is repeated until the proper number of bands has been placed around ,the bundle. As' the bundle moves forwardly, the end presses onto the roller 28 of the receiving table. The bundle is then sawed transversely in alignment with the shortest strip ofiiooring contained therein, the cut being made inalignment with the end of` the table or scale.

The operator'notices the scale which indicates to him the number of surface feet therein and he marks the bundle accordingf ly so that when the bundles are shipped, each bundlehas indicated thereon the number of surface feet it contains.
