JOHN A. SEVER/IN, 01" 'WEATHEEFORD TEXAS.

Application filed December 31, 182-3.

T 0 all whom it may concern Be it known that I, JOHN A... Snvnnrn, a citizen of Czechoslovakia, residing at lVcatherford, in the county of Parker and State of Texas, have invented certain new and useful Improvements in Portable Booths or Tents, of which the following is a specification.

This invention relates to certain new and useful improvements in portable booths or tents and has particularreference to a metallic frame structure over which a canvas body is draped.

The primary object of the invention resides in the provision of an expansible and collapsible frame structure adapted to be set up in an expanded or extended position for supporting a canvas to produce a booth or tent.

Another object of the inventi'onis to provide a portable booth or tent of circular formation, wherein an upper frame structure is formed of a plurality of pivotally connected links, the links being relatively associated to produce a circular frame when extended and to be supported at the upper ends of upright rods or posts, while a canvas cover for the frame structure embodies a series of windows and a door opening.

WVith the above general objects in view and others that will appear as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying draw ing and claimed.

In the drawing, wherein like reference characters designate corresponding parts throughout the several views,

Figure 1 is a front elevational view of a portable booth or tent constructed in aceordance with the present invention,

Figure 2 is a horizontal sectional view taken on line IIII of Fig. 1,

Figure 3 is a top plan view of the upper frame structure constructed from a plurality of pivotally connected links,

Figure 4: is an enlarged fragmentary top plan view of the upper frame structure showing the circumferentially extending links 'at the outer ends of the pivotally connected radial links with the operating cord for collapsing the upper frame structure,

Serial No. 683,767.

Figure 5 is a fragmentary top plan view of the upper frame structure in collapsed condition,

Figure 6 is a fragmentary perspective view of the upper frame, and

Figure 7 shows detail sectional views of the connection between the upper end of the vertical supporting post and one of the circumferentially extending links, and also a sectional view of the connection between the outer ends of a pair of radial links and ad jacent ends of a pair of circuinf .ential links for rigidly holding the upper frame structure in an expanded position.

Referring more in detail to the accompanying drawing, there is illustrated a portable booth or tent wherein ametallic frame structure having vertical SLIPPOIiTlDg posts, carries at the upper end thereof a frame structure embodying a plurality of pivotal-- ly connected links constituting a circular formation wherein the radial links 1 are pivotally connected at their inner ends as at 2 with the outer ends of adjacent links of the several pairs of links pivotally connected as at 3. A plurality of outwardly curved links 4 substantially half as long as the links 1 are pivotally connected together as at 5 with the outer ends thereof pivotally mounted upon the pins 3 pivotally connecting the outer ends of the links 1 the links 4- when the up per frame is expanded as illustrated in Figs. 3 and i being arranged in circular formation.

The supporting posts 6 for the upper frame are preferably in the form of tubular members as illustrated in Fig. 7 having screw studs7 threaded into the upper ends thereof, each stud carrying a threaded pin extension 8 that projects through an open ing 9 formed in several of the links 4, :1 thumb nut 10 threaded on the pin extension 8 rigidly supporting the upper frame upon the post 6. The lower ends of the post (3 carry caster rollers 11 to permit the structure to be shifted from one position to an other.

The outer end pivotal connection between two of the links 1 and adjacent ends of the links 4 as shown in Figs. 3 and 7 embodies a threaded pin 12 having a thumb nut 13 mounted thereon to be properly tightened for holding the upper frame structure in a rigid condition when extended as illustrated.

A cord 14- is associated with the upper frame structure to effect collapsing of the several links comprising the same, to the position illustrated in Fig. 5, the cord being anchored at one of its ends as at it to the inner end of radial link 1, and freely passing through eyelets 15 at the inner ends of alternate links 1. The free end of the cord passing through the last link of the series, depends fromthe upper frame structure for ready grasping when it is desired to contract or collapse the frame structure. When the frame structure is in the position shown in Figs. 1 and 3, the thumb nut 13 is tightened to hold the several links against relative move ment, and when it is desired to contract collapse the upper frame structure, the thumb nut 13 is loosened and the free depending end of the cord 14- is pulled. The outer links 4t are then moved on their pivotal connections 5 with the pivotal connections In inwardly, while the links 1 are moved on their pivotal connections 2 and 3, with the inner ends of the links 1 moving toward each other to assume the positions shown in Fig.

A canvas canopy covers theframe structure and includes a hood 17 and an enclosi-ng side 18 provided with transparent window openings 19 and door flaps 20.

The booth or tent is of a portable type and is capable of being readily shifted upon the castersll and the same may be easily collapsed as above described for purposes of shipment or storage.

lVhile there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood thatminor changes may be made therein without departing from the spirit and scope of the invention as claimed.

lVhat is claimed as new is i. In a device of the class described, a frame structure for supporting a canopy, embodying an upper frame and vertical supporting posts, the upper frame being formed of a plurality of substantially radially disposed links pivotally connected :1 t their inner and outer ends, and pairs of pivoted links pivotally attached at their outer ends to the pivotally connected outer ends of the radiallinks.

2. In a device of the class described, a frame structure for supporting a canopy, embodying an upper frame and vertical supporting posts, the upper frame being formed of a plurality of substantially radially disposed links pivotally connected at their inner and outer ends,

pairs of pivoted links pirotully attached heir outer ends to the pivotally cou- .ed outer ends of the radial links, us for rigidly holding the upper link e in extended position and means for ntnictiug the same.

in a device of the class described. a frame structure for supporting a canopy, embodying an upper frame and vertical supporting posts, the upper frame being formed of pivoted links providing circular formation when extended, and means associated with the outer pivoted end of a. pair of links for holding the same in extcnded position.

in a device of the class described. :1 frame structure for supporting a canopy, embodying an upper frame and vertical supporting posts, the upper frame being formed of a plurality of substantially radidisposed links pivotally connected at their inner and outer ends, pairs of pivoted links pivotiilly attached at their outer ends to th pivotally connected outer ends of tho iadial lin 1 and means associated with the outer l, l .'*)i'Q(l end of a pair of links for holding the same in extended position.
