FORM FOR CONCRETE SHIPS.
Specification of Letters Patent.
Patented Jan. 28, 1919.
Application filed June 17, 1918. Serial No. 240,348.
To all whom it may concern:
Be it known that we, MARTIN H. MARTIN- snN and CHARLES MARTINSEN, citizens of the United States, residing at Bryn Mawr, in the county ofKing and State of Washington, have invented certain new and useful Improvements in Forms for Concrete Ships, of which the following is a specification.
This invention relates to improvements in forms for concrete ships and has for its principal object to provide an improved and novel form construction for use in the building of concrete boats; to provide means in a concrete ship form whereby individual sections of the form may be removed, to permit the trowel finishing of the surface, and
again replaced; to provide a form made up of a plurality of individual sections of similar construction.
Other objects will appear as our invention is more fully explained in the following specification, illustrated in the accompanying drawings and pointed out in the appended claims.
In the drawings Figure 1 is a cross sectional elevation of our form shown erected ready for concreting. Fig. 2 is a fragmentary side sectional elevation of same showing{the construction of the form.
eferring more particularly to the drawings numeral 1 indicates sills upon one of which a longitudinally grooved keel way 2 is placed. A tongued keel block 3 cooperates with the keel way 2 and is slidable therewith at the time of launching the ship. On either side of keel way 2 and at right angles thereto a series of grooved form way beams 4: are arranged in parallel pairs and abut against the sides of the keel way 2. A similar number of frames, each of which includes a tongued base 5 cooperating with beam 4: and an upright 6 secured to base 5 and a diagonal brace 7 connecting base 5 and upright 6, are arranged on either side of the keel block. The frames are tied together by ties 8 and the uprights are connected transversely the keel by a cap 9 which is removable. The frames are connected together in pairs longitudinally by sheeting 10 which is nailed to shape blocks 11 which in turn are secured to the frames. Sheeting 10 conforms to the desired shape of the side of the ship.
Genius 01! this patent may be obtained for After the form has been completed by an inside centering 12 the space intermediate the centering and sheeting is poured full of concrete. After the concrete has taken its initial set the forms are removed one section at a time and the surface of the concrete trowled to a smooth surface after which the section of form is replaced. The sections are made small enough to permit of their removal without endangering the safety of the ship. In the removal the section of form is slid along the beams 4 in a direction at right angles to the keel of the ship, after the cap 9 has been removed.
While we have shown a particular form of embodiment of our invention, we are aware that many minor changes therein will readily suggest themselves to others skilled in the art without departing from the spirit and scope of the invention, and we therefore desire to avoid being limited to the exact form shown and described.
Having described our invention, what we claim as new and desire to protect by Letters Patent, is
1. In a device of the class described, the combination of a longitudinally grooved keel way, a tongued keel block cooperating with the keel way, grooved form way beams arranged in pairs and at right angles to the said keel way, tongued frames cooperating with the said beams and slidable therewith, whereby the frames may be moved inde pendently at right angles to the keel block.
2. In a device of the class described, the combination of a longitudinally grooved keel way, a tongued keel block cotiperating with the keel way, grooved form way beams arranged in pairs and at right angles to the said keelway, tongued bases cooperating one with each beam, an upright secured to each base, a diagonal brace connecting each beam and upright, into a frame, sheeting connecting adjacent frames into a section of forms, whereby the entire form is composed of individual sections.
In testimony whereof we affix our signatures in the presence of two witnesses.
