To all whom it may concern:
Be it known that I, Gnonon Y. PooooK, a subject of the Kin of England, and resident of the city of %eattle, county of King,
I; and State of Washin n, have invented cerand with certainty of securing proper'form in the finished product.
The object of my invention is to reduce the labor cost of doing this work and to msure a more perfect product.
One of the objects of my inventionis to provide a mold from which the completed product may be readily removed.
In the drawings I have shown a construction which is now preferred by me for this purpose. I y
Figure 1 is a top plan view and Fig. 2 a side view of the completed mold.
Fig. 3 is a vertical, lon 'tudinal section, taken at one side surface 0 the central vertical web of the supporting base, the frame of the pontoon beingshown in place.
Fig. 4 is a transverse section.
The mold, as herein shown,is intended for use in building the exterior skin of a pontoon intended or use upon hydroaeroplanes. The general shape of this pontoon resembles a section cut from a cylinder, the cut extending a little to one side of'the central line so as-to include at its lar er part,
a little more than half of the c lin er. In constructing a pontoon 0 this sort an inner frame work is employed which contains longitudinal members, one of which 7 consists of a board which, in the device illustrated. lies in a central longitudinal plane and others, as 70, consist of bars which extend along the edge of the flat or bottom side of the pontoon, this correspondin in its position somewhat to the position 0 the nwale of aboat. In addition this skeleton frame employs transverse bulkheads 71 and frame members. Consequently, if, as is applicants practice, the frame work is assembled before applying the outer skin, the mold for receivin the same must have a longitudinal slot Iorreceivin the central I web and transverse slots receiving the trans- Specificatlon of Letters Patent.

versely extending members of the frame. Where circumferential ribs are used, ooves, as 63, 64, for receiving these must provided.
The mold is constructed upon a fixed base or trestle 1 which is provided with longitudinal and transverse members designed to give it stiffness and rigidity. These members comprise a central plank or web 10 which is placed on edge, and other planks 11, which are placed in horizontal planes, as well as suitable supporting legs. This frame work also includes certain vertical planks 12 and 13 upon which are placed staves 14, which outline the form of the mold upon which the skin is to be shaped.
These parts, as mentioned, form a structure rigid with a base 1, and the upper portion thereof, forming the mold proper, is
providedwith transverse slots 6, 60, 61, and
'62, and any other grooves or slots which may be required, as the grooves 63, 64, to admitthe structure of the pontoon frame. The central web 10is preferably so shaped on its upper edge as to form a support for the central web or frame portions of the pontoon frame. The side bars 70 of the pontoon frame may also be supported by bars or strips 72 which are secured to the planks or vertical members 12 of the mold. In Fig. 3 the frame work of the pontoon structure is shown in place. The particular structure of this frame work, aside from the features mentioned, may vary as desired or necessitated by the requirements of the completed product.
'The design of the pontoon for which'the mold herein shown has been planned, contains strips 70 which extend along the lower edge thereof and lie inside of the skin of the pontoon. In consequence, any mold which while being applied to the frame, must have a member, or members, which extend over this strip. To secure this result and yet to permit ready removal of the pontoon after the skin has been applied, I provide is designed to form a bearing for the skin forming the skin, brads or tacks ma spond. When in place, these restupon the marginal strips 70 of the pontoon frame and when the com leted pontoon is removed, these are raised with the pontoon andtthen removed therefrom.
,All of these sections of the mold over which the skin is bent in order to shape it, are provided with an exterior metal surface consisting of plates 5, so that,,li)n e driven at any point desired and wi be clenched on the inside.
The type of construction contemplated for this skin is two la ers of veneer which are extended dia on in opposite directions. The inner ayer 1s nailed to the members of the frame and the outer layer, in addition, is nailed to the inner layer at regular in't ervals', all over its surface. latter nails will be automatically clenched by contact of the nails with the interior surface of the mold.
By the use of a mold of this sort the skin may be a plied to the frame rapidly, without re umng the services of highly specialize experts. At the same time, the shape is uniform and may he secured without re- These' quiring special care. Also, the frame is held in uniform and fixed position so that when the work is done, the shape of the finished product is uniform and true.
What claim as my invention is:
1. A mold for use in applying the outer skin of boat-like structures comprising a form having slots therein to receive the inner frame of the boat structure and having loose slab-like sections at the sides adapted to lift off with the completed shell.
2. A mold for use in applying the outer skin of boat-like structures comprising a form having slots therein to receive the.
inner frame of the boat structure and having loose slab-like sections at the s1des adapted to lift off with the completed shell, the exterior surface of the mold sections being metal faced to form nail-clenching surfaces. t
3. A mold for use in applying theouter skin of boat-like structures comprlsmg a form having an exterior outline conforming to the'interior outline of the shell, sa1 d form being slotted transversely and longitudinally to receive the correspond ng members of the boat frame, and having loose slabs at its sides adapted to fit inside the unwale member of the boat frame and to ift'ofi' with the boat structure.
