Application June 27, 1941, Serial No. 400,112

9 Claims. (Cl.13515) Generically this invention relates to tent construction but is more especially directed to the shackle features of such construction.

The principal object of this invention is the provision of a fiat compact tent pole shackle having means for securing the shackle to the tent top in a single operation to effect a concealed leakproof jointure, the combined structure being thin in cross sectional area and presenting a smooth roof surface.

One of the principal objects of this invention is the provision of a shackle structure adapted to be supported by and to receive the dowel portion of the tent pole and embodying a unique means of attaching the canvas to the shackle structure and at the same time presenting bearing surfaces for contact with the pole and dowel portion.

Another important object is the provision of a shackle structure including a shackle plate having oppositely positioned shackle elements, said plate having a central opening adapted to register with a similar opening in the tent top and a grommet extending through the plate and tent openings with its ends crimped, respectively,

points and a tubular member insertable through said aperture and tent top and adapted to have" its ends clamped in overlying relation with the tent top and plate surrounding said opening to unite said parts, the mounting of said plate and the connection of the guy ropes with said shackle being such that, the supporting stresses will be on the shackle structure irrespective of the expansion and contraction of the tent top under varying climatic conditions.

Still another important object of this invention is the provision of a tent structure including wall and quarter pole plate-like shackle structures clampingly secured to a tent top in a manner to present a flat pleasing appearance, at the same time concealing the jointu're of the shackle and roof around the pole opening, and a pull-up rope attaching means carried by said plate, the construction of the wall shackle being such as to permit a fiat seam between the outer end of the top and the point of attachment of the down 7 rope.

With these and other objects in view, which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawing, in which i like characters of reference indicate like parts throughout the several figures, of which:

Fig. 1 is a vertical section through the top of the tent and portion of side wall.

Fig. 2 is an elevation of the outside of the tent showing the side wall and edge of the top. Fig. 3 is a section taken on the line 3-3 of Fig. 1.

Fig. 4 is a View showing a portion of the top of the tent looking from the inside on line 44 of Fig. 1.

Fig. 5 is a section on the line E5 of Fig. 4. Fig. 6 is a section on the line 6-6 of Fig. 1. Briefly the shackle constructions with which I 'am familiar have proven deficient in many respects; for instance, what is known as a one-way shackle, an iron ring, or a rope-eye splice for the wall pole opening, as well as others. All of these constructions require considerable hand sewing and leather reinforcing. Such constructions not only require extra handwork but increase labor cost and. presents a thick and unsightly structure, and it was to overcome such deficiencies that I designed the tent shackle construction forming the subject matter of the instant invention, by providing a shackle structure for attachment to the top of a tent embodying a, fiat plate element having a central opening, shackle elements secured to said plate at diametrically opposite points for attachment to the top and wall structure supporting ropes and a tubular element extending through the openings in the plate and canvas top with the ends in clamping relation with the exposed surfaces of the canvas top and plate for sealing and concealing the jointure and forming a supporting bearing for engagement with a tent pole. The tent top is attached to the supporting ropes and shackle structures in such manner as to compensate for the stretching and. shrinking of the material owing to climatic changes, whereby the consequent wear and tearbeing such as to permit a flat seam or roof surface between the outer edge of the top or roof at the point at which the splicing of the down rope begins which not only facilitates manufacture but presents a more pleasing appearance.

In the illustrated embodiment characterizing this invention there is shown in Fig. 1 a fragmentary sectional view of a tent A illustrating my improved tent construction including wall pole shackle B and quarter pole shackle C operatively positioned in the tent top 5.

The quarter pole shackle B in the present instance comprises an annular plate 6 having a central opening I and is formed at one edge with aperture 8 in which is mounted shackle link or element 9 slightly closed intermediate its length as at E0. Said plate is formed at its diametrically opposite edge with a similar opening 8 adapted to receive a link H narrowed at one end as at l2, its outer end being enlarged and formed to present a substantially straight upper edge i3 and mounted in said .enlarged end is a metal egg thimble l4. Adjacent opening 8 in which is mounted link H, plate 6 has a perforation 8 in which is mounted a ring or link to which is adapted to be suitably .connected one end of 1a pull-up rope attached to the .top of the wall for use in raising and lowering the Walls. Attached to the inner end of link H is a wall pole anchor or jump rope Iii for a purpose directly more fully appearing.

Adapted to be mounted in opening I is a tubular element or grommet I! one end terminating in lateral flange l8 adapted to overlie the surface of plate 6, the tubular body extending through said plate and canvas top 5 and while said grommet may be formed of one piece, in the present instance is formed with a ring portion I'ShaVi-ng a beveled inner edge .20, the upper edge 'e-f said grommet is complementally beveled and is adapted to *be crimped as at 2| into binding engagement with ring 4 9 seated on the upper surface of top 5 to clampingly and directly unite the top 5 and shackle plate 6 to form a watertight jointure and secure the shackle in operative position, not only concealing the line of jointure but presenting a pleasing appearance and uniting the parts into a substantially thin flat assembly.

It will be noted that in the present instance the tent top 5 has extra strip of material 22 securedbystitching .23-at its edges. At one edge said stitching also secures the folded over edge of tent wall portion 24, said wall portion being gathered at its edge underlying said link to provide an opening 25 to accommodate link :II as will be apparent without further discussion. Suitably secured to the .outer surface of wall .24 and underlying the outer .edge of top v5 is an eave rope '26. This rope extends through thimble M in link i-l.

Attached to the outer end of link II is a wall guy rope 27 and secured to the link 9 is a section rope -28 suitably secured by stitching 29 to the rangement of the shackle B and link I I is such as .to permit a hat seam .35 toextend from grommet l to the edge of the top 5, except presenting a slight curve at the edge overlying link I I, said top at its edge being further secured to eaverope 26 by stitching 34 so that the roof has .no substantial humps but presents a substantially "smooth surface throughout its exposed surface area.

The-tubular or grommet elements of shackles 1 The ar-.

B and C are each adapted to receive a respective pike 3| of a tent pole 32 and to be supported on seat 33 of said pole. As the center or ridge poles, quarter poles and wall poles are of similar construction it is not deemed necessary to illustrate or describe more than one. The shackle C is similar to shackle B except that instead of two apertures 8 it has four equi-spaced diametrically opposed apertures 8a which are similar to apertures 8 described in connection with said shackle B. Mounted in each of the apertures 8a are links 34 substantially closed adjacent plate 6 as at 35. Opposite links 34 are attached to section ropes 28 and the remaining opposed links 34 are attached to the horizontal or quarter band ropes 36, the spliced portions of which are secured to the under surface of roof 5 by stitching 31.

Fig. 5 illustrates the manner of attaching the spliced portion of ropes 28 and 3G to said roof portion by stitching 31, the ropes throughout their remaining length being secured by stitching '29, similar to ropes .28.

The tent .top or roof at each point where a quarter pole shackle C is positioned is provided with an extra piece or pieces of material secured to the under surface of the top 5 by annular rows of stitching similar to the manner in which section 22 is secured as heretofore described and through which extends the shackle grommet I! as described in connection with shackle B. Since shackle C is constructed and attached to the top C identically in the same manner as shackle B, a detailed description of the components of shackle C is deemed to beunnecessary.

In connection with both shackles B and C a slight fullness or slack in the canvas material of top 5 between the shackle connections and its attachment at the spliced ends of the connecting ropes is provided as at 33,, so that the strain of supporting the top will be on the ropes and shackles and the tearing away of the material at point of connection with the shackles and also with respect to the expansion and contraction of the roof material at such point will be prevented.

From the above it will be apparent that I have designed a tent construction including unique shackle structures, said shackles being clampingly secured to the tent top in such a manner as to present bearing surfaces for engagement with the supporting base of the tent poles and the pikes extending through the shackles, as well as concealing the lines of jointure with the tent top material, and the clamping end of the connection forming in effect a continuation of the top surface, such construction at the same time presenting a neat, compact assembly, the combined assembly being such as to tend to prevent disintegration of the tent construction at such points by adding to the life of the tent, said shackle devices being simple in construction, manufacturable at a'saving in production cost, and easily and quickly installable .at a saving in time and labor, and eflicient for the purposes intended.

Although in practice it has been found that the form of the invention illustrated in the accompanying drawing and referred to in the above description as the preferred embodiment is the most efiicient and practical; yet realizing the conditions concurrent with the adoption of the invention will necessarily vary, I desire to emphasize that various minor changes in details of construction, proportion and arrangement of parts, may

be resorted to within the scope of the appended claims without departing from or sacrificing any of the principles of this invention.
