SHIP FRAMING Application filed February 9, 1927.

The objects ol this invention are to so an range and construct the framing as to increase the stability of such training, by maltinp; the vertical members continuous and suit ably connected to the main hull and to simplify the construction of a, vessel aiter franr inn is erected by permitting the work to proceed simultaneously onv any dcclt level or on the uppermost level, so as to provide shelter and so facilitate the worlc it proceeds later on the lower levels. Also, to increase the structural eiliciency of the traminp; by assembling: all the members, viz: vertical, horizontal and diagonal of each main transverse frame, into one rigid unit, to which the longitudinal members or girders tor the support oi. intermediate deck beams may be connected.

In accomplishin the objects above set forth. I have found it necessary and desirable to make certain rather extraordinary changes in the ship construction. Such changes will he de cribed in the specification which follows and the accompanying drawinns sl'iould be referred to for a complete understanding of the specification which follows.

In the drawings:

Fig. l is a perspective view showing a 33 means for supporting longitudinal and transverse girders.

Fig. 2 is an elevation of a section of a ship constructed according to my invention.

Similar reference numerals indicate like par s in all the figures where they appear.

As set forth in the preamble, one oi? the principal objects of this invention is to reduce vibration, and another to increase rigidity.

I have found that vibration can to reduced and rigidity increased, by certain clninp'es in the framing of a ship. These changes consist of extending the umights as shown at 1, 3 and l as cmitinuous columns or members from the main hull structure 5 upward through all of the decks, terminating under the uppermost deck of the superstructure.

In the past, it has been customary to construct a ship in what might be termed units,

the hull and main. deck being constructed and the decl: laid. The uprights fortlie next deal; are then placed in position and secured, and the next deck is then applied.

in my system, all uprights from the hull 65 to uiulcr the topmost deck are erected, and

deck beams for all decks are placed in position, and thereafter the decks are construct- Gil, or arranged upon the deck-supporting means. liy this method of construction, greater rigidity is obtained, and it is possible to work on all decks simultaneously. In other words, I generally follow the principle employed in the construction of steel buildin arranging all of the framing as the first o :ration, and thereafter securing the plat- 11g and decking, and any other structure thereto, the particular object being to have the upright longitudinal and substantial members continuous, and it because of the hi size oi the ship, it is not possible that these members should he formed of one piece, they shouhl at least be formed so that the sections abut, to be secured so as to form substantially (pntinuons members. Y5

The ship of which I have shown a section of small detailin the drawings may be an exclusion boat or river boat, and the decks may be named as follows; the uppermost deck (3 is the boat deck, directly under the 0 boat deck and at 7 is the observatioi'l deck. At 8 I show the salon deck, and the main deck is indicated at 9. As desired, my method of framing may be employed in boats of any (les n or intended for any particular op- 55 oration. I show this construction only because of its simplicity and ease of observation.

The hull frame 5 may be of any shape or outline. It will be understood that the frames vary in shape from bow to stern to impart to the hall the shape desired. The frame 5, then, is selected arbitrarily, and without the intention of suggesting that its shape has any important bearing upon my invention.

The deck members or transverse girders as shown at 9, 10, 11 and 12, may be supported by any suitable means, such as the channel M bars 13, or the longitudinal girders 14, shown under the deck 9, the channels 13 being supported by angle plates 15. The separate supporting means as shown, are not intended as modifications of supporting means, but are intended to show that each successive lower deck should be provided with increasingly heavy supports. v

The arched construction employed in Fig. 1 does not change the principle of construction herein set forth as the column portions of the arches extend through for the next lower deck to be received directly upon the next lower columns or arches, therefore, for r all practical purposes, a portion of the arches merely serves as a continuation of the vertical column.

Theuse of continuous main framing columns makes it possible to employ these columns as ventilating shafts as shown at 16 and 17 in Fig. 1, where ventilators are placed upon the centermost columns. Hollow columns may be employed throughout and may serve to facilitate the installation of piping as well as ventilators and may conceal the otherwise unsightly runs of drainage, heating and air piping, telephone, signal, lighting and other wires and cables.

These hollow columns may have openings or doors suitably arranged as shown at 18 a and without afi'ecting the structural efficiency of the columns.

Modifications may be made within 'the scope of the appended claims, without departing from the principle or sacrificing the 5 advantages of the invention.

Having carefully and fully described my invention, what I claim and desire to secure 1. In a multiple deck ship a ship framing 40 having substantially continuous upright members extending from the main hull framing to the uppermost deck which they support and passing through all intermediate decks and having means thereon for supporting such intermediate decks.

2. In a multiple deck ship a shipframing wherein all uprightsare substantially continuous and having their support upon the hull framing and passing through intermediate decks, to terminate under the uppermost deck and substantially continuous transverse members supported by said upright members and adapted to support intermediate decks.

3, In a multiple deck ship a ship framing having hollow upright members supported upon the hull framing and continuing through all intermediate decks, and means adjacent each successive deck for supporting said deck upon said upright members.

Signed at the city, county and State of New York, this 3rd day of Sept, 1926.
