Description:

This invention relates to welding tables and more particularly to a sheet metal welding table, the top of which is adapted to receive and retain a plurality of refractory brick or the like, which when in position form a complete relatively solid table top for gas welding purposes.

Among the objects of the invention is to provide a rugged, simple type of knock-down gas welding table, whereby the parts of the same may be shipped to save freight and whereby said parts may be quickly assembled to form a rigid practical gas welder's table of few parts, of standardized preformed construction, and which may be quickly assembled to provide a rigid table top adapted to support firebrick to form the top of the table; to provide these and other objects of the invention which will be apparent when taken in connection with the following specification and the claims and the drawing, wherein: Figure 1 is a perspective view of my improved gas welding table; Figure 2 is a section taken on the line 2-2 of Figure 1; Figure 3 is a section taken on the line 3-3 of Figure 1.

Referring now to the drawing in detail, the legs 2 of the table comprise four upstanding angle irons, the flanges of which are preferably 90 degrees apart so that when the legs are placed in the corners in spaced relation a flange of each leg is disposed in a plane common with the flange of the next adjacent leg.

In order to rigidify the lower end of the legs each leg is provided with a cleat-like sheet metal angle iron member d which is welded thereto and comprises a horizontal flange and a vertical flange, which cleats are welded to the inside vertical walls of each leg.

A shelf-like member 6 of sheet metal construction and having a vertically depending flange 8 terminating in an inwardly extending flange 10 is provided in such a manner that the vertical wall 8 lies flush against the vertical wall of the cleat 4 and the inwardly extending flange 10 and overlies and is supported upon the horizontal wall of the cleat 4, and thus the shelf rigidly interconnects the four legs.

In addition, dividers or partitions are provided in the form of L-shaped sheet metal strips which in dimension preferably extend the length of the shelf. There are a number of these dividers 12 and these lie in parallel spaced-apart relation with their shorter flanges welded as at 14 to the top surface of the lower shelf, whereby the shelf and its welded-on divider rigidly sustain the legs in erect reenforced rigidifying position and wherein welding rods may be placed between the partition members 12. The space between s the innermost divider and the front of the shelf o may be used for other storage purposes.

A plurality of side panel members 13, each formed of sheet metal, is provided with their ends suitably perforated to receive bolts passing r through those flanges of the corner legs which lie in a common plane. Thus, the four panel members rigidify the four legs by interconnecting them and at the same time form ornamental panels for the side portions of the table at the top.

Each panel if desired at its lower portion is provided with an inwardly extending flange 20 and the panel member just below this flange 20 as at 22 may be welded to the inside vertical o wall of the angle iron directly at the corner, as shown in Figure 3. In addition, the upper portion of each panel member is provided with an outstanding horizontally disposed flange 24 and an upstanding flange 26.

25 Suitable means is provided for reenforcing the table along its central zone. This means comprises a plurality of strips, four in number, two of which, as at 28, and two of which, as at 30, lie parallel to opposed pairs of sides of the panel :;0 member. Each angle iron of the angle iron strips is preferably welded together to form a rigid hollow rectangular structure. The angularly disposed flanges of this hollow structure provide a vertical wall and a horizontal wall, the latter lying in a plane of the horizontal flange 24. The shorter pairs of sides 30 of this hollow structure are bolted as at 32 to the adjacent end panel so that this rigidifying structure is suitably secured to the rigid panels.

'0 A top for this table is provided in the form of a plurality of firebricks 34 or the like, which are adapted to lie with their outer ends on the flanges 24 and with their inner ends overlying and resting upon the horizontal flanges 28 of 415 the central rigidifying member. The table top is formed preferably three bricks wide so that the intermediate or central brick rests upon the horizontal flanges 28 of the rigidifying member, whereas the outer bricks, as shown in Figure 3, 50 likewise rest thereon with their inner ends but have their outer ends resting upon the flanges of the panel member. The bricks when disposed in solid formation form a complete solid refractory table top for the table to sustain the gas 55 welding operations.

Obviously the invention is not limited to the specific forms disclosed herein but is capable of other modifications and changes without departing from the spirit and scope of the claims appended hereto.

The invention is hereby claimed: 1. A gas welding table comprising four corner legs, each having flanges 90 degrees apart and lying in a common plane with the flange of another leg, four sheet metal panel strips disposed vertically and having their outer ends connected to flanges of the leg at the inside walls of said leg, said panel strips providing outwardly extending horizontal flanges and an upwardly extending detaining flange, a rigidifying and supporting member comprising angle iron strips angularly disposed and interconnected to form a substantially hollow rectangular figure providing spaced horizontal flanged walls lying in a common plane with and spaced from the horizontal walls of said panel members, the common plane of said horizontal flanges lying substantially below the tops of said upwardly extending detaining flanges.

2. In a gas welding table, the combination of four corner legs of angle iron construction, four sheet metal vertically disposed panels each having their outer ends interconnected to flanges of said leg members, the upper portions of each panel extending outwardly and then upwardly to form a peripheral horizontal ledge, a rigidifying member connected to the vertical walls of certain of said panels and providing spaced-apart horizontally disposed flange-like supports extending longitudinally of the table in a horizontal spaced-apart relation throughout the central zone thereof and firebrick arranged threedeep forming the top of said table, the central row of brick having their opposed ends sustained by the spaced-apart horizontal flanges of said rigidifying member and the two outer rows of brick having their inner ends supported on the horizontal flanges of said rigidifying member and having their outer ends supported on the horizontal ledge formed by said panel members.

3. In a gas welding table, in combination with four corner legs of angle iron construction, panel members disposed vertically and interconnecting said legs, said panel members having outwardly extending horizontal flanges and terminating in vertically extending flanges forming a retaining wall, spaced-apart strip-like supports interconnecting opposed walls of said panel members, said supports lying centrally of the table top in spaced-apart relation, the upper portions of said supporting members forming horizontal brick supporting surfaces lying in the plane of the horizontal flange of said panel members and a plurality of firebrick or the like closing the top of said table and supported in part by the horizontal flanges of said panel members and in part by said spaced-apart horizontal rigidifying end supporting strips.

4. In a gas welding table in combination with leg members, an upward peripheral frame supported thereby, said frame including a peripheral horizontal flange or ledge and a surrounding vertical flange, frame rigidifying means disposed within said peripheral horizontal flanges and spaced therefrom and a plurality of firebricks having their outer end portions lying upon and supported by the horizontal peripheral flange and having end portions juxtaposed and supported by said rigidifying means and forming a closed top for the table.
