' 0 FRAME CONSTRUCTION.

Application filed August a, 1910. Serial in. 576,416. 7 a

To all whom it may concern:

Be it known that I, HENRY J. Casanova, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Frame Construction, of WlllCll the following is a specification.

The invention relates in general to frame construction adapted to be used for all purposes where a light frame-Work is desired, and particularly adapted for the framework in flying machines of all types.

The invention resides primarily in the means for securin two pieces of material together, as part 0 the framework, consisting of tie rods and bars, the former being capable of resisting tensional strains so as to prevent the se aration of the frame-work, and the latter eing capable of resisting compression strains to prevent'the collapsin of the framework. a

Further advantages of my invention will more fully appear in the specification, and some of the manners in which the invention may be employed are shown in the accompanying draw1ng,'in which,

Figure 1 is aside'elevational view of my improved frame construction, Fig. 2 is a sectional view on the section line 22-, of-

Fig. 1, Fig. 3 is an enlarged detail sectional view, and Figs. 4, 5, 6 and 7 are similar views to Fig. 1, showing modifications of frame-work to which myinvention may be applied. V

'Referring now morejparticularly to the drawing, and specificallyto Fig. 1, a ham boo frame 10 serves as the body ortion of r the frame with curved pieces 0 material '11 secured'thereto, to either one of which may be attached a suitable material. The.

curved frame members 11 are secured to the. bar 10 by means of suitable tie rods 12 which are preferably made of steel, passing throu h both theframemember's 10 and '11 and he d thereto by means offsuitable nuts 13 and washers 14. It is of course understood. that as many ftie rods may be employed as are deemed .necessary for proper construction work. A tubular bar 15, through which the tie .rods 12 pass, is interposed between curved member 11 and the bar 10, the ends of such bars 15 either bearing directly upon op sing 'surfaces'oftheframework, or such en s mai'bear upon the washers 14 or su1t-' able bloc members (not shown).

the bars 15 which have greater compression stren th thanthe tie rods 12, and such bars also serve to prevent the tie rods from bucklin In Figs. 4, 5, and 7' modified forms of frame construction are shown, all of which embody the invention as described in connection with Fig. 1, except in Fig. 5 plates 16 are interposed betweenthe ends of the bars 15 and the frame work, and metal clips 17 are used in lace of the washers 14, which give additiona strength to the frame membcrls if made of wood orotherfibrous mate- ..rla

In my preferred form of construction the frame work is lnade of bamboo or other light-woods,"the tie rods being-made of steel and the bars -15 of aluminum. It is also desired that the corner pieces 18, washers- -14, plates 16 and clamps 17 be also made of aluminum. The main bars 10 of the frame constructions shown in Figs. 4'and 5 may be of any suitable light material, and the main bar in Fi 1.

In 6 a slightly modified form of construction is, shown for securing two arts of a frame-work at ri' ht angles to eac other. The tie rods 12 an the bar members 15 areemployed in this construction, but as both of the frame members 10 shown in this figure are of bamboo a 19 is placed at plug one end of the frame 10. w ich' abuts a ainst the other art of the frame, and the tie rod 20 passest rough said plug and through the frame 10 for preventing lateral dis lacement of one member relative to the ot er.- The ferrule 21 surrounds the end of the frame 10 adjacent the, plug 19 to prevent the breaking away of the side walls of the frame.

It is obvious that a great many different forms of frames may be constructed wherein myinvention is applicable, and therefore without confining myself to the particular constructions herein shown I claim: 1

'.A frame construction for aerial vessels comprising two frame members suitably 10 of Fig. 7 is of bamboo, as shown spaced apart, hollow metal' tubes interposed outerends of said tie rods and nuts for between said frame members and having drawing said frames, tubes and washerstotheir ends abutting against said 'frames,- gether. I metal washers interposed between the ends HENRY J. CASANOVA. of the tubes and the frame members, light I Witnesses:
