Original application, October 17, 1950, Serial No. 190,625. Divided and this application January 3, 1952, Serial No. 264,807

l Claims. (01. 100-25) This application is a division of my application Serial No. 193,625, filed October 17, 1950.

This invention relates to improvements in apparatus for packaging lumber, particularly random lengths of flooring.

Heretofore has required 60 to 70 man hours to load a railway car with bundles of lumber, such as random length flooring, and wherein the individual bundles were placed lengthwise of the car. To unload at the destination required about the same number of man hours.

It has been found that this same operation requires but approximately 3% man hours to load and the same time to unload when my new and improved package of lumber of random lengths is used.

A further object of this invention is to provide a new and improved apparatus for packaging in dividual bundles of lumber of random lengths into a. compact package, which simplifies the banding of the package and the removal from the apparatus and which also provides a plurality of bins within the smallest possible floor space.

A further object of this invention is to provide a new and improved apparatus for packaging individual bundles of lumber that facilitates the loading and tying from the floor level with a minimum of reaching for the average man.

A further object of this invention is to providea new and improved apparatus for packaging individual bundles that comprises a multiplicity of bins to provide for the separation of various grades and diiferent species of lumber.

'To accomplish the above objects I provide an apparatus for packaging lumber, particularly random length flooring, which consists of a bin provided with means for guiding the tie band around the package preparatory to tying the same, and which is provided with means that enables the picking up of the package by a fork truck.

Other objects and advantages of this invention will become apparent as the discussion proceeds and when taken in connection with the accompanying drawings, in which:

Fig. 1 is a perspective view of a double-deck packaging bin embodying my invention, showing the upper deck empty and the lower deck with a completed package ready to be removed therefrom;

Figs. 2 and 3 are front and side elevational views, respectively, of a completed package embodying my invention, loaded on a conventional fork truck;

Fig. 4 is a perspective-view of an individual bundle of random length flooring of substantially the same length as it emerges from a packaging;

a double-deck packaging bin, which preferably is of a. length a little less than the width of abox car. The bin it consists of a pair of lower front and back base members or sills H, and the numeral l2 designates a pair of front and back headers which also form sills for theupperreceptacle and are located approximately midway of the height of the bin [0. Each of the sills ii and i2 is provided with a pair of elongated notches 13 located approximately midway between the ends of the sills, for the purpose of receiving a fork 3! on a conventional lift truck 35 (Figs. 2 and 3 second pair of notches, somewhat T-shaped designated generally by the numeral it. Each of the notches M is located, as best shown in Figs. 1 and 5, near, but preferably spaced inwardly from, the ends of the sills H and I2. The notches hi are adapted to receive spacer strips of wood id, or the like, which may be of any size desired, but which should be of a length equal to the width of the package when completed, and which support the package on a floor, with the material of the package in spaced relation to the floor. The ends of the strips of wood it are beveled 01? at approximately 2. 45 angle, as shown in Fig. 5. This beveling reduces friction and enables the band to slip and be pulled tight around the package and also prevents injury to the edges of the flooring strips of the bundle by pressure of the hand against said edges. In addition,the beveling also reduces friction as well as forms a skid to facilitate the sliding of the package over floor surfaces.

In addition to the strip l4, located on the underneath side of the package, a second strip it, also with the ends beveled at approximately a 45 angle, is located on the top of the bundle underneath each band or strap 23 for the purpose of further reducing friction thereof as the strapis: pulled tight around the package.

A double-deck bin is illustrated and described becauseit has been foundadvantageousto have such a bin to provide for packages of different length boards, whereby one bin can be loaded while the other is being tied and the package being removed. This arrangement provides two or more bins within the smallest possible floor space 5 and also facilitates the loading and tying from the floor level without too much reaching for the average man. However, it is. to. be understood that any number of decks can be incorporatedin" one bin.

Located in the bottom of each of the notches. I4 is a further notch I5, which is for the purpose of receiving a guide member: Ii which is: channel-shaped in cross section and is also bent back upon itself in U-shape. Thespecific purpose of the guide member I6, will;be: discussed in detail later. The members. I6; may; be new manently secured to the sills II and I2 or may be slid into the notches I5 before or after the bundles are arranged in the bin II).

On either side of the front sills I I and I2, and connected together thereby; are upstandingside posts IT which are connectedtogether at their top ends by-means-of atransverse cross member' or header 18. Also supporting the rear sills: I I and: I 2 and connected together thereby is a pair of upstanding side posts I9-3 These parts I I; I2; I8 and" I9 form an opemframework. Surround ing the two sides and the back ofthe-biir I8 are panels: 20; The panels- 20 forming the back (notshownl may-beadded; if desired} to g-ive added strength to l the 1 bin I 0&

guide member I6. It will be seen from a study of Figs. 1 and 5, that by virtue of the shape of the guide member I6, the strap 28 may be inserted in either the top end or bottom end of the guide I6, and, as it is pushed through the length of the channel, will be caused to bend back and around the package 21 in the bin and finally extend out from the opposite end of the guide from: whence itcan be readily grasped. The two ends of'the strap 28 are then put into ajoining apparatus of conventional design and a: tie 29 is made in the strap. As the strap 28 isitiedaboutfthebundle 21, it will be pulled out of the guide member through the slots 2I and the-open'side of the guide member, and down tightly around all: four sides of the completed package: 21. While" only two straps have been shown: about each. package 21, any number of straps desired may be provided, but for each strap desired there is provided a guide member I6.

After the completed package 27 has been strapped and tied; andis'still in the bin IIl', a'lift' truck 3Il having a fork 3I- ismoved'upto'the bin I0 and the fork is slid through the notches I3 under the package 21, which now can be considered as-a' pallet unit; The fork 3| then is raised'until it supports the package 21, on which it-can be readily removed from the bin I0 and transported to a'-- box car, truck or the like; or may be m-oved directly to a warehouse for storage. The wooden spacer strips I4 being held on-the bottom of the package 2 by the straps 28; afford-an elevated support for the bundle'and makeit= possible to slide the fork- 3-1 of the lift truck thereunder when thepackage i'l isplaced of the box car; and with the individual'boards also extending crosswise'of the box cari As the bands 2 3 and 2 8 "extend around the bundles and 5 package crosswise, this'willput these bands- 23 and" 28 lengthwise of the box car; Regardless of how many'individual packages arethen loaded iirthebox-car and- -whether theyare stacked one i on top of the other, there willbe'practically no loosening eife'ct on the packages, bundles, bandsor individual boards duringtransit.- Longitudinal' shifting of theboards and packages in the car is reduced to a minimum by this -arrangement because thejolting due tostarting and stopping of the trai-nis' sidewise' ofthe package r'ather than lengthwise; Furthermore, there-Willbe no"tendency-for'the ties 23- and 28 to catch on each other and besheared oif, as would occur if stacked lengthwise of the-car.

Considerable loading advantage is alsoob'- tained byproviding apackage of this type. I The packages,'- being ofa len'gthiapproximately equal" to the width of a box car, are simply picked' up Icy-"the *fork' 3'] of a lift" truck 3 I and the truck run" into th'ecar. The packages are then spotted or placedin the car'oneither'the floor or stacked upon each other 'di're'ctly b'y' thetruck', and'the amountofhandling ofthe package in the-. car is also reduced-to amin'imum.

The packages 21' are then removed from the box car and are taken to the local lumber yard or warehouse, wherein, .in their. compact condition, they can.readilybestoredina minimum amount of space... Whenit is .desired to remove 'the flooring from the package, the straps 28 arebroken andsremoveduand the individual bundles 22 5 are office for production record. The remaining two tallies are left attached to the package 21. In shipping, one of the remaining tallies is removed for count and billing, and the other tally goes along with the completed package for the cust-omers count.

It is to be understood that variations and changes may be resorted to without departing from the spirit of my invention as claimed.
