S. C. FORRESTER TENT Filed Feb. 21, 1929 2 Sheets-Sheet 2 Patented Aug. 18, 1931 UNITED STATES PATENT OFFICE SAMUEL C. FORBESTER, OF ATLANTA, GEORGIA, ASSIGNOB TO FULTON BAG & COTTON MILLS, A/ CORPORATION OF GEORGIA TENT Application filed February 21, 1929. Serial No. 341,800.
Generically this invention relates to tents, but it is more especially directed to the supportin frame structure for the type known as pole ess umbrella tents.
I An important object of this invention is the provision of what might be termed, a center poleless foldable supporting frame structure for a tent of this character.
One of the principal objects of this invention is the provision of a skeleton frame for supporting a tent cover, including means for expeditiously efl'ecting its lateral and vertical expansion to stretch and render taut the said covering supported thereby, and to elimu; inate the old-fashioned center pole, leaving every inch of space inside the tent covering unobstructed and usable.
Another object of this invention is the provision of a tent supporting structure of go this character comprising a spider-like roof or top frame formed at the lower edges with longitudinal side bars, each of said bars comprising telescopic sections, telescopic standards adapted to support said spider-like structure, and manually operable means for locking each of said side bars and supporting standards in any desired position of longitudinal and vertical adjustment, respectively.
A still further object of this invention is 80 the provision of a collapsible tent frame of this character comprising detachable and foldable sections to effect the expeditious erection of the frame, and to enable, when not in use, its being packed into a small compass. ,5 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 drawings, in which like characters of reference indicate like parts throughout the several figures, of which:
Fig. 1 is a perspective view of the improved frame operatively erected, with the tent cover in fragmentary section;
Fig. 2 is a fragmentary elevation of the cap plate, spider arm and coupling member;
60 Fig. 3 is a fragmentary elevation of one of the supporting standards and knuckle joint member;
Fig. 4 is a fragmentary longitudinal section of one of the supporting standards and knuckle joint members;
Fig. 5 is an elevation of the knuckle joint member and a portion of supporting standard showing pin 38 in position;
Fig. 6 is a cross section of the knuckle olnt member shown in Figs; 4 and 5;
Fig. 7 is a bottom planWiew of the cap member;
Fig. 8 is a cross section of the cap member shown in Fig. 2; and
Fig. 9 is a fragmentarylongitudinal section ofthe side bar sections 19 and 20 with the thumb screw elevation.
The tent frame structures of this general type with which I am familiar have'.proven unsatisfactory by reason of their not being readily adjustable to tighten the tent covering over the supporting frame, the com onent parts not being sufficiently folda 1e and detachable to permit packing into a com-' compact form when not in use and readily transportable from place to place, too bunglesome to handle and expensive to manufacture, and requiring a perpendicular rod, or pole, with arms radiating to the four corners to support the frame, thus interfering with overhead space, and it was to overcome such deficiencies, and to provide a tent structure comprising a skeleton roof supporting frame including expansible side bars having means for readily locking the said bars in any desired adjusted position, and expansible standards for supporting the skeleton frame, each standard comprising telescopic sections having similar means for locking the sections in any desired expanded or retracted position, and means for erecting each of the standards in a relaxed position by use of a knuckle joint, which when straightened out, automatically stretches the tent cover taut, adjustably effect and maintain the covering uniformly taut over said frame in accordance with varying climatic conditions, that I designed the structure forming the subject matter of this invention.
In the illustrated embodiment characterizing this invention there is shown a tent cover supporting frame A, comprising a skeleton roof supporting frame B, mounted on and supported by standards C.
The skeleton frame B comprises a. cap plate or umbrella-like member 5 formed on its upper surface with a perpendicular lug 6, and on its under surface with downwardly and outwardly projecting spider-like ri ht angular bifurcated arms 7, extending slightly beyond the circumferential edge of said memer 5, each of said arms adapted to receive the flattened or reduced end 8 of the respective spider arms 9 rotatably secured therein by rivet or bolt 10 extending through registered openings 11 and 12 in said arms 7 and 9, respectively. It will thus be seen that the arms 9 are hingedly secured to said cap plate and may be folded into parallelism with each other when not in use, likewise a projection 5' extends downwardly from cap 5 to facilitate erection of frame by means of any one of the four standards, and to provide a means for supporting lantern or other light inside enclosure at night.
A substantially tubular coupling member 13 is formed with a reduced upper end 14 projecting at an angle from the main body of the member and is adapted for insertion in the lower end of one of the arms 9 and secured therein by a rivet or pin 15. The lower end of member 13 terminates in a reduced portion 16 adapted for insertion in the upper end of one of the supporting standards C for a purpose hereinafter more fully appearing.
The said coupling member 13 is formed intermediate its length, in the present instance, at points spaced from its lower end,
with substantially laterally extending lugs' 17 at right angles with respect to each other, but at such an angle that when they are brought to a horizontal plane the reduced end portion 16 will project downwardly and outwardly at an angle corresponding to that of the supporting standard G into the upper end of which it is adapted to be inserted, as clearly shown in Fig. 1 of the drawings. The coupling member 13 is also formed on its upper surface intermediate the lugs 17, with an upwardly curved lug 18 adapted to extend through an eyelet or other fastening means in the tent cover D as will be understood without further explanation, serving as a means of support for guy rope when needed.
In orderto space and support the arms 9 n proper position, and to add rigidity to the frame, a side bar E is adapted to interconnect the coupling 13, in the present imstance, on each of the four sides of the tent. The side bars E are formed with the telescopic sections 19 and 20, respectively. The ends of the bar E are adapted to engage lugs 17 of the respective couplings 13, and in order to lock or maintain the sections 19 and 20 in any desired adjusted position with respect to each other, a rojection or thickened portion 21 is forme on the inner end of section 20 provided with a threaded openin 22 extending through said projection to t e inner surface of section 20, and a. threaded thumb screw 23 is adapted to engage said opening 22 and contact the telescoping end of section %)9 to rigidly unite said sections into a rigid ar E.
Each of the supporting standards C comprises section 24 adapted to telescopically receive one end of the section 25 which is maintained at any desired adjusted position by thumb screw 23 mounted in the end of section 24 similar to section 21, and as its operation with respect to standard C is identical with that of side bar E, further explanation is thought to be unnecessary.
A knucklejoint or hinge member F is in serted in the section 25 at a point substantially central of standard 0, comprising the hinged sections 26 and 27, respectively, the lower end of the section 26 is adapted to be inserted in section 25 and secured therein byrivet 28, its upper end terminating in bifurcated jaws 29 extendin on one side upwardly to form the wi ening portions 30,
said portions being formed with apertures 31 offset from the axis of section 25. The sec-:
tion 27 is formed with a sleeve portion 32 adapted to receive the lower end of one section 25 and is cut out to form bifurcated jaws 33 adapted to embrace jaws 29 and formed with an opening adapted to register with apertures 31 toreceive pivot pin 34 and the lower end terminating in a secured portion 35 constituting a stop to align the section 25. This hinged knuckle joint enables the sections 24 and 25 to be folded into parallelism;-
A stopper 42 is inserted in the lower end of.
each of the supporting standards C to prevent the bottom of the standard from wearing a hole in floor of the tent cover, and where conditions may require the end of the standard to be closed.
From the above description it is apparent that I have designed a tent structure of great adaptability, capable of being easily erected or dismantled, and embodying means for expeditiously effecting tightening or loosening of the tent cover on the frame under all conditions, by means of expansible side bars and supporting standards, capable of being folded into compact form, providing an absolutely rigid structure without obstructing antoo inch of space from bottom to top, manufacturable at a low cost and efiicient for the purposes intended.
