Application February 16, 1944, Serial No. 522,576

^ of the built-up deck described to provide vertical 3 Claims.

This Y invention relates to auxiliary decks of ships and provides portable built-up plates of varying size removably attached to movable deck beams.

An important object of the invention is to provide a portable frame to carry temporary and removable decking of timber therewithin on which heavy objects such as airplanes may rest in shipment and tofacilitate desired secure fastening of the object to available ship parts.

Other objects include the provision of means in such a portable frame for securing removable fastening of the frame to available steel deck beams; for economy and efficiency in manufacture and use of such a frame; for the utmost in strength of parts to enable carrying of great loads on such a frame; means for permanent secure assembly of the frame parts; and means for manufacture of the frame from a single strip of angle iron.

These and other objects will'be readily understood from study of the following description and attached drawing forming part thereof.

In the drawing,

Fig. 1 is a plan View of my steel frame shown fastened to deck beams of a ship.

Fig. 2 is a side elevation of the device of Fig. 1.

Fig. 3 is a section view in elevation taken on line 3-3 of Fig. 1.

Fig. 4 is a plan view of a strip of angle iron showing parts cut away to provide for bending of the strip and butt jointing of neighboring edges and eliminating welding of three vertical joints V of the Fig. 1 frame.

Referring now to the drawing, my frame I IJ having four sides I I, I2, I3 and I4 at right angles with each other is preferably formed of four pieces of relatively strong angle iron of suitable size. The corresponding planarly horizontal and vertical edges are preferably Welded together to form butt joints at I-I and V respectively. There is thus formed a frame having a horizontal shelf or flange I5 on which the ends of suitable timber strips W may rest to form a timber plate housed on shelf I5 as shown in Figs. 1 and 2.

A suitable number of angle iron brackets I6 are welded at X to the outer vertical surface of opposite sides I2 and I4. Said brackets are provided with suitable bores or slots IBI thru which bolts l1 or other fastening means may pass to engage plates or clips I8 beneath steel beams B of for example a spar deck of a ship to thus removably x the frame I0 to the beams B. Such beams are desirably lockably movable on tracks T providing selective positioning on the tracks for obvious reasons such as to permit clear-away passageway to lower decks.

It is seen that the base portion A of such things as airplanes (which in shipment is usually a tripod device A) may rest on the timber plates and that fastening means such as cable and turnbuckle ties may tie the plane at rest to suitable xed parts of the ship.

A series of my frame plates may be arranged to abut each other at the sides Il and I3 to prevent sidewise movement thereof relative to the ship.

While I have shown four brackets it is understood that at times two I6, lEa, will sufl'ice, i. e., one on each of two opposite sides diagonally with each other to effect tie means of the frame with two beams as shown.

At times I prefer to form my frame from a single strip of angle iron 2U, out of which I cut the triangular material formerly in space 2| to provide for bending of the strip and butt jointing of neighboring corresponding edges to thus eliminate ywelding of three vertical joints V. To make the frame the portions are bent about points 22, 23 and 24 to form right angle bends thereat and the edges 2| l, 2|2 come into abutment to form joint H.

The description is intended to be illustrative rather than limitative.

I claim:

1. A spar deck platform comprising a four sided metal frame consisting of a single angle bar bent to form the corners, said angle bar having a lower horizontal flange extending inwardly to form a support shelf having upper and lower sides, a vertical flange extending upwardly having outer and inner sides, floor members removably supported by said horizontal flange and lying between said vertical flanges, angle bar brackets each having a vertical flange secured to the outer sides of the frames Vertical ange and having a lower horizontal flange-shelf extending outwardly from the frame, the bracket shelves having upper and lower sides and bores therethru to receive fastening means for attaching the frame to a structure, the lower sides of the bracket shelves being flush with the lower side of said support shelf whereby said platform may rest on said structure.

2. A spar deck platform comprising a four sided metal frame consisting'of a single angle bar bent to form the corners, said angle bar having a lower horizontal ange extending inwardly to form a support shelf having upper and lower sides, a vertical ange extending upwardly having outer and inner sides, angle bar brackets each having a vertical ange secured to the outer sides of the vertical flange of the frame and each having a lower horizontal flange shelf extending outwardly from the frame, each bracket-shelf having bores therethru to receive fastening means for attaching the frame to a beam of a ship and also having upper and lower sides, the lower sides of the shelves being flush with the lower side of said support shelf whereby said platform may be firmly supported on the beam, said bores being 10 arranged to straddle said beam, and means (zo operating with said bores for removably fastening the platform to the beam.

3. The device of claim 2 wherein the means cooperating with said bores include a bar having bores corresponding with the bracket bores and under said beam, bolts thru said bores and removably fastening the bar, beam and bracket together.

JOSEPH WILLIAM YELLEN.
