My invention as will presently become apparent may be used with any number of different kinds of boxes and used for packing various different articles. The present embodiment of my invention illustrated and described in this application is used for packing fabric articles, such as underwear or similar garments, and is particu- (ill more fully described in detail.

larly adapted to be used with boxes in which the garments are laid relatively flat and inserted endwise into the box.

The particular box illustrated in this application is shown in detail in Fig. 12, and is indicated in its entirety at 9. This box comprises a back 10, a front 11; and side walls 12 and 13 all formed from a single piece of material and glued or pasted together in any suitable manner. One end of the box indicated at 14 may be closed in any suitable manner as by flaps glued or pasted together. The other end of the box is adapted to be closed through a flap 15 extending the entire width of the box and issuing outwardly from the back 10. This flap is provided with a tab 150 adapted to be inserted into the box proper. In addition two side flaps 16 and 1'7 are provided which extend outwardly from the sides 12 and 13. These flaps may be of any suitable length though in the formation of the box in the most economical manner, said flaps are usually of the same length as the flap 15. Along the top 11 of the box is formed another flap 18 which is folded along the line 19 and constructed with a tab 20. This flap is preferably of a width considerably less than the width of the box and the tab 20 is adapted to be inserted into a slot 21 in flap 15 when the flaps are folded in position. In closing the box, the flaps 16 and 1'7 are first turned in and the flap 1%) folded upon the same with the tab 150 extending into the box. The flap 18 is next folded over the other flaps and the tab 20 inserted into the slot 21 holding all of the flaps in closed position.

The device for inserting the articles into the box 9 is best shown in Figs. 1, 5 and '7. This de vice comprises a base 22 which may be constructed of wood or some other suitable material. When the base 22 is constructed of wood the same is preferably covered at one end thereof with a plate 29 of sheet metal which extends completely across the same. Upon this plate is disposed two angle members 23 and 24 which are spaced from one another a distance equal to the width of the box to be employed and which form abutments for holding the box in position. These angle members may be secured to the base through screws 25 or through any other suitable means, which pass through the flanges thereof and through the plate 29. A similar angle member 26 extends between the two angle members 23 and 24 and serves as a stop for retaining the box in proper position when the articles are packed within the same. This angle member may be attached to the base 22 by screws 31 the same as the other angle members. .In the use of the device, the box 9 is placed between the abutments 23 and 24 and against the stop 26 and is so retained while the same is being packed.

Extending in the same direction as the abutments 23 and 24 I provide two angle iron guides 2'7 and 28 which are provided with upwardly extending flanges 29 and with flanges 30 adapted to overlie the base 22. The flanges 30 are preferably received in grooves 32 formed in the base 22 and face one another. The flanges 29 of the guides 2'7 and 28 lie inwardly of and parallel with the inner surfaces 33 of the abutments 23 and 24 and are spaced a short distance from the surfaces thereof for a purpose to be subsequently Upon the base 22 and to the left of the plate 29 when the device is viewed as in Fig. '7 are disposed two parallel plates 34 and 35 which overlie the flanges 30 of the guides 2'7 and 28. These plates are attached to the base 22 through screws'36 and 37 rotaivs of which the screws 3'7 pass through the flanges 30 of the guides 2'7 and 28 and serve to hold said guides in rigid position. The plates 34 and 35 are spaced from one another as designated at 38 and the spaced portions of these plates overlie a groove 39 in the base 22 coextensive with the length of said plates to form a T slot 40 having a function to be presently described in detail.

In mounting the box, the same is placed between the abutments 23 and 24 and against the stop 26 with the bottom 10 thereof lying directly upon the plate 29. In order to hold the various flanges of the box in place, a number of devices are used which will now be described in detail. For the purpose of retaining the flap 15 in open position, the base 22 at the ends of the guides 2'7 and 28 is slightly depressed or formed with a transverse beveled groove 41. At such locality the extreme end 42 of the plate 29 is bent to follow along the depression or groove 41 and reaches down to the lower end thereof. The ends of the plates 34 and 35 adjacent the groove 41 are doubled back upon themselves as indicated at 43 in Fig. '7 to overlie the extreme end of the portion 42 of the plate 29. The doubled over part 43 of the plates 34 and 35 are preferably on a slant with respect to the portion 42 of the plate 29 and is spaced therefrom so that said parts form a groove 44 for the reception of the extreme end of the flap 15. In inserting the box in the device, the flap 15'of the box is placed between the abutvments 23 and 24 and slid along until the free edge of the flap 15 engages within the grooves 44. The box may then be dropped in position behind the stop 26.

For the purpose of guiding the flap 15 into the groove 44, the two extreme ends of the flanges 29 of guides 2'7 and 28 are formed with upwardly curved edges 45 which assist in directing the flap 15 as the same is moved along the portion 42 of plate 29. The fiap 15 is further directed into said groove through the rounding of the plates 34 and 35 formed by the doubled over portion 43 thereof.

The side flaps l6 and 1'7 of the box 9 are held in position by the following construction. The abutments 23 and 24 are preferably constructed as castings and immediately beyond the ends of the guides 27 and 28 are formed with depressions or angular pockets 46 and 4'7. In these pockets are disposed leaf spring fingers 48 and 49 which are secured to the abutments 23 and 24 within said pockets through screws 50. The fingers 48 and 49 are normally sprung outwardly from the surface 33 of the abutments 23 and 24 to leave grooves 51 and 52 therebetween into which said flaps may be directed upon inserting the box into the device. When the flaps l6 and 17 lie between these fingers as shown in Fig. '7 said flaps are retained in open position.

For holding the flap l8 and the top 11 of the box 9 in open position, a structure is employed which is best shown in Figs. 5, '7 and 8. To the upper portions of the abutments 23 and 24 are attached through screws 53 two leaf springs or arms 54 and 55 which extend upwardly therefrom as most clearly shown in Fig. 6. These arms have mounted upon the extreme ends thereof a transversely disposed round rod 56 which is attached to said arms through screws 57. Upon the central part of this rod is secured a U-shaped spring clip 58 having an upper portion 59 and a lower portion 60. The upper portion 59 is attached to the rod 56 through screws 61 while the lower portion thereof is normally in engagement with the rod 56 and extends downtime the flange is moved upon the portion 77' of the surface 81 of the former 76. As the sup-- port continues to move toward the box 9, theflange 70 follows along the twisted surface 81 of the former 76 and is gradually elevated. 'Fig. 10 shows the relation of the parts as the elevation of. the flange 70 commences. In Fig. 11 the disposition of the parts is shown with the flange 70 further elevated. When the structure reaches the: portion 78 of the surface 81 of the former 76 theflange 70 is disposed at right angles to the base 22: andthe body of the support and parallel with. the flange 91. It is to be noted that the flange 85- of former 83 terminates when the surface 81. indicated at 78 becomes at right angles to the: base 22 so that the flange 70 of the support 71 may lie in close contact with the flange 69. The parts when so disposed are clearly shown in Fig. 9 and the function of the keeper 82 to hold the: flange in position is clearly brought out in thisfigure. As the support is further moved along' the guides 27 and 28, the flanges 70 are progres-- sively formed and bent in erect manner and the: support directed into the box proper. As soon asthe flange 70 passes the portion 78 of the surface 81 of the former 76, the same engages the spring fingers 48 and 49 which direct the runners formed. thereby into the box. At the same time, the: upper portion of the garment may engage the portion 60 of member 58 and the corresponding portion 64 of members 62 and 63 to guide thesupport with the garment thereon into the box.

.During the insertion of the support and article into the box, the member 26 previously referred. to serves as a stop for preventing the movement of the box away from the various members for holding the flaps in open position. By reciprocating the plunger 72, the full amount, the support 71 with the garment 66 applied thereto may be completely inserted in the box. Thereafter it is merely necessary to remove the box by lifting thesame outward from the base 22 at the end there-- of adjacent the stop 26 and close the flaps 16, 17,. 15 and 18 in the requisite manner. It is to be.- noted in Fig. 2 that the flanges 79 of the support 71 are slightly longer than the body thereof. This. provides a space for the portion of the garmentturned over the edges of the support and serves to hold the support immovable within the box through contact with the protruding ends of said flanges and independent of the garment. It can. readily be comprehended that the packing of the articles within the box can be rapidly effected due to the simultaneous bending of the flanges and insertion of the supported article into the box. When the support is within the box the spring of the flanges 69 and 70 causes the flange 70 to lie snugly against the side walls 12 and 13 of the box so as to hold the supportimmovable in that direction. The flange 70 is preferably constructed of a height equal to the height of the box with the ends thereof limiting the movement of the support 71 toward and from the front and back 19 and 11. lhe flange 69 is preferably half the size of the flange 70 so that the support 71 is medially positioned within the box.

My invention is highly advantageous in the following respects. With my invention the articles can be rapidly packed within the boxes. When the articles are disposed within the box, the same are held from movement through the supporting member therefor and the supporting member is retained in position independent of the 69 follows between the flange 85 of the former 83 and the flange 29 of the guide 28. At the same:

article carried thereby. The flanges for engagement within the box are automatically bent upon insertion of the support into the box. The device can be constructed at a nominal cost, is very simple to. operate, and will not readily get out of (order.
