2 Claims. (Cl. 73-100) Our invention resides in the provision of novel means for subjecting a hogshead panel topressures similar to those it will receive in use in order to eliminate defective panels from hogsheads.

It is an important object of our invention to provide a testing device which will simulate actual conditions to which the panel will be subjected when incorporated in a hogshead.

Another object of our invention is to provide a testing device having a wide range of pressures which may be applied against the particular hogshead panel as desired.

A further object of our invention is to provide a testing device having means for clamping a hogshead panel thereon so as to enable the safe use of high pressures in rality of hogshead panels. are joined by hoops 11 and hoops and liners 12. Later they will be sawed along the dotted lines 13 in order to form a plurality of slats;

In order to secure accurate results in testing a questionable panel it is important that it be subjected to conditions which closely simulate those to which it will be subjected if included as one of the panels making up a hogshead. With that in mind we have constructed our testing device as follows. As perhaps best seen in Figures 3 and 4 the device comprises a table 14 mounted on legs 15 and having a suitablebed member 16. The bed order to locate whatever defects there might be in the panel.

These and other objects of our invention will become apparent to those skilled in the art during the course of the following description and with reference to the accompanying drawings, in which drawings like numerals are employed to designate like parts and in which:

Figure l is a plan view of a typical hogshead panel which will be tested by the device of this invention,

Figure 2 is a plan view of an assembly of hogshead panels such as shown in Figure 1,

Figure 3 is a plan view, with parts broken away, of the testing device of this invention,

Figure 4 is a section taken on the line 4-4 of Figure 3,

Figure 5 is an enlarged fragmentary sectional view showing in detail the latch mechanism for securing the panel in place,

Figure 6 is an enlarged perspective view showing detail of the structure of Figure 5 and Figure 7 is an enlarged perspective view showing further detail of the arrangement of Figure 5.

In manufacturing hogsheads we have found it desirable to employ panels made of plywood and the like. These panels may be assembled together in side-by-side relationship and bound by a plurality of metal straps. Following this the assembly of panels may be sawed so as to form what amounts to a plurality of slats. The sawed assembly of joined panels may then be shaped to form a hogshead after which tops and bottoms may be applied. These hogsheads are subjected to considerable pressure when they are loaded and they often are given rather rough treatment when handled in warehouses and during transportation. Accordingly it is important that the panels from which the hogsheads are formed are of good quality.

In Figure l we have shown a typical hogshead panel as indicated at 10. Workmen having a supply of these panels available will take them and place several in side-by-side relationship in order to rough out a hogshead. Three such panels have been indicated at 10a, 10b and 100 in Figure 2. Ordinarily these workmen will inspect the panel as it is put into position. If there is any doubt about the quality of the panel and its strength it is set aside for testing as will be described. The plumember 16 has upstanding sides and ends which are grooved at 17 to receive a panel member 10.. These sides and ends 18 and 19 maintain the panel 10 sufiiciently spaced from the bottom of the member 16 as to provide room for the pressure envelope 20. V

The panel 16 is maintained in position on the bed member 116 by a framework which is pivotally mounted on a shaft 21. This shaft 21 is mountedin suitable bearings 22 based on the table 14. The framework comprises the members 23 which will engage the ends of the panel 10 so as to correspond in position to the hoop and liners 12. The framework also includes a pair of members 24 which will engage the panel 10 in a position corresponding to that which will be taken by the hoops 11 if the panel ii) is included in a hogshead. The members 23 and 24 are fixed to the shaft 21. A pair of brace members 25 extend across the members 23 and 24 and may be welded or otherwise secured thereto. Members 26 are fixed to the brace members 25 and arranged to form the handle 27.

From the foregoing description it will be apparent that by grasping the handle 27 the frame structure including the members 23 and 24 may be moved from the full line position of Figure 4 to the dotted line position thereof. In this dotted line or out-of-the-way position the frame structure may rest against the stop 28 fixed on the lugs 29 extending from the bed 14. When a panel 10 has been placed in the grooves 17 provided in the tops of the sides and ends 18 and 19 of the bed member 16 the frame structure is then brought to the full-line position of Figure 4 where it will be observed that the members 23 lie across the ends of the panel while the members 24 engage the panel centrally thereof. Means are provided to clamp this frame assembly in position above the panel member 10.

A shaft 30 is mounted in a plurality of bearings 31 extending from the table 14. A handle 32 by means of which the shaft 30 may be rotated in its bearings is also fixed to the shaft. Latch means for the ends of each of the members 23 and 24 are mounted on this shaft 30. It will be understood that each of these four latch means is alike and therefore we shall describe only one.

As perhaps best seen in Figures 4 and 5 the latch means comprises a short link 33 which is pinned to the shaft 36 as indicated at 34. The latch member 35 is pinned to the end of the short link 33 as indicated at 36. The latch member 35 has a face 37 adapted to engage the end of the members 23 and 24 in the area indicated at 38. The latch member 35 may be bifurcated so as to provide portions 39 and 40 which straddle the short link 33 as best seen in Figure 7.

When a panel has been placed on the table member 16 and the frame structure including the members 23 and 24 have been engaged with this panel the various latch members 35' are then engaged about the ends 38 of the members 23 and 24. After each of the latch members 35 has been put in place the handle 32 is then moved in a clockwise direction as viewed in Figures 4 .and 5. This will rotate the shaft 30 and link 33 so as .to move the pin 36 out of vertical alignment with the shaft 30 thereby insuring that the latch members 35 will be-locked in place. This past center arrangement prevents accidental displacement of the latch members.

The pressure envelope 20 is preferable made of a strong, flexible material capablei of withstanding high pressures. -A" fitting dl connects this envelope m with a suitable conduit extending from a'source of air under pressure. Loeatedin the conduit 42'is'a regulator valve 43, anofi and on valve 44' and agauge 4S. When air under pressure is admitedwithin theenvelope 29 h will expand uniformly 'and conta'ct the underside of the panel and urge this panel tightly against the frame members 23 and 24 which'are now locked in position'by the latches 35 as described. "ln'thismiannerthe panel 10 may be subjected to whatever pressure is desired. The panel may be inspectedt'o see whether any defeets did occur as 'a result of the high pressure applied;

By locating the'memberslland 24 in positions correspending to those about which the hoops and hoops and liners 11 and 12 will be disposed if the panel is used in forming' a hogshead, and by providing the flexible envelope 20 whereby pressure is applied evenly throughciut the panel, we are able to closely approximate the conditions to whicha hogshead panel is subjected when inusel ln'this manner we can get accurate information its to whether'a questionable panel should be used or not.

i It is believed that the operation of'this device has been fully set forth above and that it is easily understood by those skilled in the art. To describe it further at this point would seem repetitious.

It will be apparent to those skilled in the art that certain modificationsmay be made in the device of this invention without departing from the scope and spirit thereof. it should be understood'that while we have shown our invention as embodied in certain particular structures and arrangements We' do not intend to be 4 limited to such structures except insofar as they are specifically set forth in the subjoined claims. 1

Having thus described our invention, what we claim as new and what we desire to protect by United States Letters Patent is:
