WOQ'DEN SHIPPING GASE.

shipment or"storage it cannot be opened 5 without breaking or marring the boards or other parts, and thus leaving tell-tale evidence that the case has been tampered with.

More specifically, the object of my present invention is to provide a sealing device of such a character and construction that it may be substantially completely embedded or concealed within the wall of the case.

This construction does not reduce the total space within the case which is available for the goods, and has no parts projecting into the case which might scratch, mar, or otherwise injure the goods or thepackages or wrappers containing the same.

My improved constructionv includes two parts or members one adapted to be secured to the wall of the case and the other secured to or engaging with the cover, and a further object of my invention is to so construct these parts that they may be easily and quickly applied in the proper relative positions for cooperation when the case is closed and sealed.

My improved sealing devices are adapted for use with various forms of shipping cases made of wooden boards. The construction of shipping case may be of the form shown in my prior Patent 1,391,470 in which there are bars or cleats extending across the top, 7

bottom and sides of thecase at right angles to the boards of these walls.

' Another form of case to which the invention is applicable is that shown in my prior Patent 1,423,317, in which there are two 7 sets of cleats or bars which extend around the case adjacent to each end thereof. In either construction the sealing device may serve to connect together the cleats at their ends.

flush with the upper edges of the upper so cleats 11, the bottom wall is secured to the lower edges of the end walls with the under surface flush with the lower ed e of the lower cleats 11, and the side we Is 13 are secured to the vertical edgesof the end walls as and with their outer surface flush wlth the outer edges of the vertical cleats 11. .Thusall of the boards of the top, bottom. and side walls are prevented from any endwise movement by cleats 11 which form the frames on. the ends. The boards of the top, bottom and side walls are held in place not only by being'nailed directly to the end walls, but also by having the outwardly projecting edge portions of the cleats 11 nailed thereto by nails extending into the ends of said boards. The cleats 11 may be secured to the body portion of the end wall by screws inserted from the inner surface. p

The entire case mayhave a. single band of cleats extending around at right angles p so A further form of case is shown in Fig;

y portion of the end 85 to the boards of the top, bottom and sides,

as shown in my Patent 1,391,470, or two bands of such cleats, one at each end of the case, asshown in my Patent 1,423,317, or there may be a larger number for long boxes. As shown, there are two bands of cleats'or bars 14 spaced a short distance from the ends.- The endsof the cleats forming these peripheral band or bands are secured together by my improved sealing detherethroughadapte to receive the cooperating member which extends through the cover. This member is shown as a simple nail or spike 24 adapted to be driven through the top wall and through the aperture in the flange or plate 22. It is provided with suitable head and shank portions. The flange or plate 22 is provided with means which will grip the member 24 and posi tively prevent withdrawal thereof. This gripping means is shown as a pair of springs 25 having their ends partiall overlapping the hole in the flange 22, an having their outer ends secured to the flange by suitable rivets. The distance between the ends of the springs is less than the diameter of the "member 24, so that as the member 24 is driven through the hole in the flange 22 and between the ends of the s rings thelatter will be deflected downwardly as illustrated in Fig. 3. The ends of these springs will grip the member 24 between them, and any attempt to withdraw the member will cause the ends of the springs to bite into the mem ber 24. and will more effectively grip it. The ends of the springs 25 may be such that they will not slip on the member 24, and therefore the more pull that is exerted on the member 24 the greater will be the gripping action. It will be noted tha the upward movement of the flange 22 wit 1 .the cover is positively prevented Ibythescrews 23 which extend into the side wall at right angles to the direction of pull on the member 24.4 It

will also be noted that the point or terminal portion of the shank of the member 24 becomes embedded within the wall of the case and cannot. contact with thegoods within the case. Thus the elements of the box which are connected by the members 20 and 24 are locked against an possible separation without breaks. I desired, the member 24 may be slightT; roughened or knurled to further insure the gripping action of the ber 20 may, if desired, be-made of a cast ing or heavy stock, and the springs of the desired resiliency. In some cases I may make the springs integral with the top flange, as shown in Fig. 5.v Here the top flange 22*is provided with a pair of parallel slits 26 which are connected by a transverse slit or opening 27 forming the two spring tongues 25 which have their abutting ends so positioned that they are forced down and resiliently grip the member 24 when the latter is driven into place as shown in Fig. 6.

One advantage of the construction illustrated is the ease with w ich the members may be properly positioned. When it is de sired to apply and seal. the cover it may be placed in position and the spikes or other members- 24 driven in until the points emerge from the under side of the cover only a slight extent and mark indentations in the edges of the case walls. The cover may then be removed and the members 20 secured in position with the apertures of the flanges 22 directly'over the indentations formed by the points of the nails or spikes 24. After these members 20 have been secured in position the cover may be replaced opening at the upper or outer end of the stud. The peripheral wall of this passage 32 may be provided with one or more longitudinal grooves 33 which are preferably tapered so that they intersect the passage to a greater extent at the upper end than at .the lower. 'Within each groove is mounted a locking ball 34 normally pressed upwardly by a spring 35 and of such diameter that when in the upper limiting position the ball surfare intersects the surface of the passage, as indicated in Fig. 9. The upper ends of the passages may be swaged over to prevent the escape of the balls. The grooves diverge to such ane'xtent that as the balls are forced down they separate to a distance which may equal the diameter of the passage 32. The cover has a hole bored therethrough to receive the head part of the stud 30, and a coacting locking mem-,

ber 36 is rovided which has a head portion 37 of a ameter greater than that in the of the head portion is less than the thickness 1 of the cover.

When the cover is in position the member 36 is placed in position as shown in Fig. 7, and then driven home as shown in Fig. 8. The balls move downwardly until they permit the passage of the shank 38 therebetween, and any attempt to Withdraw the shank will be frustrated by the wedging action of the locking balls 34. The cover cannot be removed as the head 37 is larger than the hole through the cover.

It will of course be evident that I may employ as many of my locking devices as necessary in making up a case. As an extreme,

each board might be secured at each end by one or more of the locking orsealing devices, but preferably, the case is so constructed that it is not necessary to use this sealing device except in connection with the cover. For an ordinary case with a single peripheral band formed of cleats, as shown in'my Patent 1,391470, only four of the locking devices will he necessary, that is at the intersections of the four cleats forming the peripheral band.

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

1. A shipping case having a member adapted to be secured to the inner surface of the wall of a case, and having a flange or plate extending over the edge of said wall, and a coacting member adapted to extend through the cover of the case and through said flange or plate and enter said wall, and means for preventing the withdrawal of said last mentioned member.
