HENRY W. YOST, 0F SPRINGFIELD, OHIO.
POST OR BAR.
Patented Mar. 7. 1911.
To all whom it 'may concern:
Be it known that I, HENRY IV. Yosr, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Posts or Bars, of which the following is a specification, reference being had therein to the accompanying drawings. A
This invention relates to posts or bars and is designed more p/artieularly for the construction of frames such as are employed, for example, in aeroplanes.
The object of the invention is to provide a bar or frame member which will combine minimum weight with maximum strength; and which will be so shaped as to offer a very small opposing surface to the air, a feature highly desirable in aeroplane constructions.
A further object of the invention is to provide a bar of vthis character which can be quicklyT and easily manufactured at a low cost.
In the accompanying drawings, Figure 1 is an elevation, partly broken away, of a portion of a bar embodying my invention; Fig. 2 is a sectional view taken transversely to Fig. l; Fig. 3 is a transverse, sectional View of a slightly modified form of the in vention; and Fig. 4t is a transverse, sectional View of another modified form of the invention. i l
In Figs. 1 and 2 of the drawings the bar or postis shown as hollow and as having its side walls converging toward its opposite edges. In the present instance it is also shown as comprising two sections, 1, each preferably consisting of a series of laminations, of wood or other suitable material, and curved outwardly so that when the two sections are placed with their concave faces together, the bar so formed will be of the desired shape. The degree of curvature may be varied to adapt the bar or post to the articular use to which it is to be applied IlVhen the two sections have been placed with their concave faces together their adjacent edges are rigidly connected one to the other by suitable means such as a fastening device. In the form of the invention shown in Figs. 1 and 2 this device comprises a longitudinal strip of metal bent about the adjacent edges of the two sections of the. bar and serving to clamp the same firmly together, as indicated at 2. This fastening device not only serves to secure together the two sections of the bar, butalso protects the edges of the laminated sections and is itself so narrow at its outer edge as to offer but a small resistance to the air. As stated, the material employed in constructing the sections 1 of the bar or post may be of any suitable character, but I prefer to employ wood for this purpose, and, as here sho-wn, the two sections of the post are made up of thin strips of wood lirmly united one to the other by the use of glue. To further increase the strength of the post or bar and to avoid the possibility of the sections splitting I prefer to arrange the strips of wood so that the grain of the several sections will extend in two or more directions. As here shown each section comprises three strips or laminations, the inner lamination or strip8, and the outer lamination or strip, 4, having their grain eX- tending longitudinally to the bar, while the intermediate lamination or strip, 5, has its grain extending at an angle to the grain of the inner and outer strips. In the present instance this angle is approximately a right angle, but this is not essential. The bar is also preferably reinforced by means of spacing blocks which are shaped to correspond to the cross sectional area of the bar and are fitted snugly within the same where they are secured by glue, as indicated at G in Fig. 1.
Thatl form of the invention shown in Fig. 3 corresponds to the forms shown in Figs. 1 and 2 in all respects save the character of the fastening device. In Fig. 3 this fastening device comprises an elongated block 7 arranged between the adjacent edges of the two sections, 1, of the bar and provided with notches 8 to receive those edges. The sides of the block preferably converge outwardly and are so shaped that when 4it is in place the taper of the edges will correspond substantially with the curvature of theouter surface of the bar, thus forming a smooth harmonious whole. The block may, if desired, be laminated, and, as here shown, consists of three strips, the two outer strips, 9, constituting the body of the block and having interposed between the same a thin strip 10, the grain of which preferably extends at an angle to the grain of the two outer strips, the three strips being connected by means of glue or in any other suitable manner.
That form of the device shown in Fig. 4
differs from the form shown in Figs. 1 and :2 in that it converges toward one edge only and comprises a single section. This section, which is indicated at .11, is preferably formed of a series-of layers or laminations after the manner described in connection with Figs. 1 and 2 and is bent upon itself n Vsuch a manner that the side walls converge toward one edge thereof. The edges of this one section are connected by a fastening device 1Q which is here shown as similar to the fastening device shown in Figs. 1 and 2.
It will be noted that ,in each form of the invention herein shown the bar is formed of A light material so shaped as to form a bar of very light weight but having great strength. This strength is increased by forming the bars of laminated material and arranging the grain of different laminations at an angle one to the other. In each form the bar has its side walls converging toward one or both of its edges and these side walls have their edges connected one to the other by suitable fastening devices.
The several forms of the device herein shown and described are used for the purpose of illustration only and the invention can be embodied in bars or frame members of various shapes and the fastening devices may differ widely from those here shown. I, therefore, wish it to be understood that I do not desire to be limited to the details of construction shown and described, for obvious modications will occur to a person skilled .in the art.
Having thus fully described my invention side walls converging toward the edge thereof, and a device for connecting together the comprising a hollow bar having'laminated4 side walls converging toward the edges thereof, and a fastening device for rigidly connecting said edges.
6. A structure of the character described comprisingahollow bar formed of two laminated sections spaced apart and converging toward the edges of said bar, spacing blocks arranged within said bar, and a fastening device for connecting the adjacent edges of said sections.
7. A structure of the character. described comprising a hollow bar .formed of two laminated sections spaced apart and converging toward the edges of said bar, the grain of one of the laminations of each section extending at an angle to the grain of another laminat-ion of that section. A
8. A structure of the character described, comprising a hollow bar formed of two laminated sections spaced apart Vand converging toward the edges of said bar, and fastening devices for rigidly connecting the adjacent edges of said section.
In testimony whereof, I affix my signature in presence of two witnesses.
