3 Claims.

This invention relates to a construction for a barrel head, particularly to a barrell head for a Abilge barrel. The invention also relates to a method of installing a barrel head within the end of the barrel, and to secure the same therein with re-enforcements to prevent removal of the barrel head.

More particularly, the invention relates to a barrel head construction wherein the barrel head can be inserted freely through one end of the barrel or disposition in a tapered seat provided vin the end of the barrel. After the barrel head is'positioned in the tapered seat, layers of wood veneer are then positioned above the barrel head, and in engagement therewith, and secured to the upper edge of the barrel to hold the barrelhead in position and thereby prevent its removal from the barrel.

An object of this invention is to provide a barrel head construction, particularly for a bilge barrel that is more readily assembled, and wherein, after assembly, the barrel head cannot be removed from the end of the barrel. v

A further object of the invention is to provide a barrel head construction wherein the barrel head is disposed in its proper position in the end of a barrel by means of a tapered seat and a cooperating ledge, and the barrel head is thereafter held in position by means of layers of wood veneer secured to the inside surface of the barrel adjacentvthe upper edge.

Still another object of the invention is to provide a method of installing a barrel head having the features of the foregoing objects whereinthe barrel head is permanently bonded to the barrel and is secured in position by a layer of Wood veneer also permanently bonded to the barrel and to the barrel head.

A still further object of the invention is to provide a method of installing a barrel head incorporating the features of the foregoing objects wherein the barrel head is retained in position under pressure while it is being bonded to the barrel, and simultaneously to apply pressure to layers of wood veneer to bond them to the 'barrel and secure the barrel head in its position.

Further objects and advantages will become more apparent upon reference to the accompanying `drawings and the following description in which: Y

Figure l is a perspective view of a barrel incorporating the features of the barrel head of this invention.

Figure 2 is a schematic -view of an apparatus in which theA barrel heads may be installed in a barrel.

Figure 3 is an enlarged cross-sectional view of the upper portion of a barrel showing the manner of installing the barrel head.

Figure 4 is a still further enlarged cross-sectional view of the barrel head of this invention to clearly show the glue lines and the tapered seat for the barrel head. Y

Figure 5 is a partial cross-sectional view of the manner of installing the barrel head in Ya barrel illustrating the use of high frequency energy for heating the bonding agent between the barrel head and the barrel.

The manner of installing a head in the end of a barrel, particularly a bilge barrel, has involved somewhat of a problem to obtain absolute leakproofness and to bond the barrel head to the barrel. In this invention the barrel headv and the end portion of the'barrel is -constructed Vin such a manner that the barrel head can readily be inserted into the end of the barrelandbe bonded permanently to the barrel.

While this invention is particularly illustrated and described with reference to the manufacture of a plywood barrel and the installing of 'a ply- Wood head in the same, yet it will be understood the invention is applicable to barrels that may be constructed in other Ways such as from a plurality of individual staves. Further, the barrel head may be a solid wood memberrather than a plywood construction as shown and described herein.

The principal feature of this invention is that the inner surface of the end portion of a barrel is shaped so that it has a cylindrical portion terminating in a tapered seat, the tapered seat terminatinng in a ledge. A barrel head is provided with a tapered periphery to engage the tapered seat in the side wall of the barrel, the bottom or inner face of the barrel head engaging the ledge. One or more plies of wood veneer are then positioned within the cylindrical portion of the end of the barrel with the ends joined with either a scarf or butt joint and in engagement with the inner surface of the barrel and with the upper or outer surface of the barrel head. The barrel head and the layer Vor layers of wood veneer are then bonded to the barrel and to each other, a suitable bonding agent or adhesive being provided for this purpose.

From the foregoing, it will, therefore, be apparent that the particular invention herein is not limited to the use of a plywood barrel construction. v y K In Figure l there is shown a plywood barrel l 0 which may: be constructed according to the method disclosed by CLU.k Gramelspacher. in

Patent No. 2,365,754. The barrel I is provided with the usual heads II, and may be provided with metal bands I2 to protect the barrel during handling. The upper end of the barrel will be constructed as more particularly illustrated in Figures 3 and 4.

The body of the barrel I0 may consist of a plywood wall I5, or may consist of a plurality of individual wood staves suitably secured together. The end portion of the wall I5 is pr`o`- vided with a cylindrical portion I6 that extends from the end edge I'I of the barrel toward the interior thereof. This cylindrical portion I6 terminates in a tapered portion I8 that is in the form of a truncated cone with the base portion positioned outwardly toward the end edge of the barrel. The tapered seat portion terminates in a horizontal ledge I9 which forms a stop to regulate the position of the head.

The barrell head II is a disc that may be either of a plywood construction, as illustrated, or may be a solid lmember. vThe edge Vperiphery of the head II is tapered to cooperate with the tapered seat portion I8 in the inner surface of the Wall I5 of the barrel. The barrel head disc II is, therefore, in the form of a truncated cone with the base positioned outwardly toward the end edge of the barrel.

With the barrel head in position, as illustrated in Figures 3 and 4, one or more layers of wood veneer 2| are positioned between the barrel head II and the end edge I1 of the barrel against the cylindrical wall portion IS yof the barrel. These layers of Wood veneer 2| are suitably bonded to the cylindrical Wall portion I6 and to the head II of the barrel, a bonding agent 22 being provided for this purpose.

From the foregoing description, it will, therefore, be seen that once the barrel head is installed in the barrel it becomes a permanent part of the barrel, and cannot be thereafter removed. It Will also be appreciated that since the barrel head is bonded with adhesive material to the tapered seat portion I8 of the wall of the barrel and to the Wood veneer layers 2l, that a sound, leak-proof barrel is thus obtained.

To install the barrel head II Within the end of the barrel I0, it will, of course, be understood that the end portion of the barrel, is first prepared with the cylindrical portion I6, the tapered seat portion I8, and the ledge or stop I9. The barrel head II is also lrst provided with its tapered periphery 20.

The prepared inner surface of the barrel is then coated with an adhesive or bonding agent and the barrel head is droppedv into position in engagement with the tapered seat I8 with the inner surface of the barrel head II in engagement with the ledge I9. One or more plies of wood veneer 2| are then positioned within the cylindrical portion I6, a suitable bonding agent being provided between the layers of wood veneer and between the wood veneer and the barrel I0.

A pressure member is then brought down upon the upper edges of the wood veneer sheets 2|, which at this time may still extend above the upper edge I'I of the barrel. This pressure member forces the wood veneer sheets 2| downwardly within the cylindrical portion I6 of the barrel into engagement with the outer face of the barrel head II to thereby force the barrel head into engagement with the tapered seat lil and the ledge I9. Heat is then applied to the wood veneer sheets 2| and to the barrel 4 head II to bond the adhesive, or the adhesive may be an air drying adhesive.

The pressure applying device may consist of a head 25 that has a downwardly extending annular flange 26 that is adapted to engage the outer surface of the Wall I5 of the barrel when the head 25 is in the position shown in Figure 3. The head 25 carries a flexible bag 21 that receives iluid under pressure through a pipe 28. The fluid admitted into the interior of the bag 2l may be hot and it may be circulated continuously within the bag 21 by providing a suitable outlet at a position remote from the pipe 28.

With the head II of the barrel and the wood veneer sheets 2| in the position shown in Figures 3 and 4, pressure may be introduced into the flexible bag 2'I and thereby expand the wood veneer sheets outwardly against the cylindrical wall I6 of the barrel I0, the ilange portion 26 of the head 25 forming an outer wall form or support for the upper edge of the barrel. The pressure m'ay be retained in the bag 2l until the adhesive material has set, either as an air drying adhesive or under heat as applied through the fluid admitted into the bag 21, or by the use of external heat, such as in a hot room or oven.

An apparatus in which pressure can be applied upon the heads of the barrel during assembly bonding is illustrated diagrammatically in Figure 2. The press may consist of a bed 30 which carries a hydraulic motor 3l having the ram 32 extending from the bed of the press.

The press will also be provided with a head 33 which carries a hydraulic motor 34 having a ram 35 extending through the head 'of the press. The rams 32 and 3,5 carry the pressure heads 25V and 25a, previously described. The hydraulic system for operating the hydraulic motors 3 and 34 mayY consist of a pump 4|! which receives fluid from the supply tank 4I through the suction line 42. A pressure relief valve 43 relieves excess pressure from the hydraulic system above a predetermined value.

Fluid is delivered from the pump t@ through the discharge line 44 into the floW control valves 45 and 4E. The iiow control valve 45 has the service lines 4l and 48 which supply fluid under pressure to opposite ends of the hydraulic motor 34, to cause reciprocation of the ram 35. Similarly, the flowV control valve 46 is provided with service lines 4S and 5@ to control the motor Si.

The flow control valves 45 and it have exhaust lines 5i and 52, respectively, lwhich discharge into the supply tank lil. The flow control valves 45 and 4E are thus what is termed a four-way control valve to alternately supply iluid to opposite ends of a hydraulic motor while exhausting llud from the end of the hydraulic motor opposite to that into which iluid under pressure is supplied, to thus control reciprocation of the hydraulic motor. Y

The ilow control valves 45 and 46 may be operated separately or together. `As illustrated in the drawing, a manual control 55 is provided for moving the internal mechanism of the valve to regulate the direction of flow of fluid through it. To supply iluid under pressure into the flexible bag 2l, the pipes 28 and 28a. are connected with a source of fluid under pressure, such as the pipe 5|), having a control valve 6I therein. The iluid supplied may be either gaseous or liquid, and may be a hot fluid for the purpose of heating the bonding agent, as previously described.

In Figure 5 there is shown an alternate method of heating the bonding agent between the head l I and the wall I of the harrel and between the sheets of wood veneer 2l. In this arrangement the pressure applying device 25 is provided with a metal annular ilange 26a, the main body of the pressure applying member 25 either being of insulating material, such as Wood or the annular flange 26a may be insulated from a metal member which may form the body of the pressure applying device 25. A thin annular metal sheet 63 is placed between the expansible bag 21 and the inner wood veneer sheet 2l. The metal sheet 63 and the ange 26a are adapted to be connected to a suitable source of high frequency current by means of the

electric lines

64 and 65.

After the head of the barrel is placed in assembled condition as shown in Figure 1 and pressure has been applied to the expansible bag 27, high frequency current will be introduced into the electric lines 6A and 65 to heat the bo-nding agent and cause it to set. In this case, preferably, a thermosetting resin is used as the bonding agent.

While the device disclosed and described herein constitutes a preferred form of the invention, yet it will be understood that modifications that fall within the scope of the appended claims are intended to be included herein.
