UNITED STATES PATENT OFFICE FREDRIC O LOVEJOY, OF ALBANY, NEW YORK.
CAM P-STOO L.
SPECIFICATION forming part of Letters Patent No. 455,345, dated July '7, 1891.
Application filed June 30, 1890.
To all whom it mwyconoern: @[Be it known that I, FREDRIC O. LovEJoY, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented certain new and usefullmprovemen tsin Camp-Stools; 'andI do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7
My invention relates to improvements in campstools formed of separable sections adapted to be readily connected together for use or folded into a small package, which may be conveniently carried in a bag or pocket when desired. I
The objects of my invention are set forth in connection with the description. These objects I accomplish by themeans illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a campstool embodying my invention and arranged for use. v Fig. 2 is a side sectional elevation of the lower central portion of the stool, showing in dotted lines the position of the arms when folded and not in use. Fig. 3 is a plan View of the under side of a socket-head with which the arms engage to form a hinge-connection. Fig. 4 is a plan view of a hingeblock adapted to be adj ustably connected with the socket-head to form a portion of the Fig. 5 is a perspective View of the fastening end of one of the swinging arms. 1
. As represented in the drawings, the upper and lower sections composing the stool are substantially alike. Each section consists of a series of swinging arms 0, hinged to a central post having a socket-head for receiving The sections are connected together by means of a swivel-joint formed by the lower end of the upper post engaging With a socket formed in the upper end of the lower post, by means of which the upper section may be turned independently of the lower section. A flexible seat D is secured to the ends of the arms 0 of the upper section in any suitable manner, and a flexible sustaining-base M maybe secured to the lower series of arms. The arms 0 are made nearly U-shaped in cross-section, as
Serial No. 357,306. (No model.)
shown in Fig. 5, and tapered from their journaled ends to their other extremity.
The socket-heads A and B, formed on the central posts A and B, are shown provided with curved transverse grooves 6, adapted to holdthe ends of the arms G, which are provided with curved edges 0 corresponding with the curvature of the grooves 19 in the sockethead. A boss Nis formed on the socket-head and provided with a threaded bolt G, which is secured to the socket-head either bycasting the boss around the bolt or by means of a thread-connection. A hinge-block F issenut, and is preferably provided With a square hole f to correspond with the square shank of the bolt G to prevent the block from turning. The inner edges 0 of the extremity of the arms bear against the surface of the hinge-block F, which may be provided with transverse grooves f or made with an unbroken surface. The hinge-block and sockethead together form a hinge with the ends of the arms, and the parts may be adjusted by means of the nut engaging with the threaded end of the bolt G, so as to readily take up all lost motion, and thereby insure a continuous and uniform action of the several parts.
WVhen constructed in the manner shown, the weight of the sitter is not sustained by a single pin, as in the case of the ordinar T hinge, but is distributed over the entire curved edge 0 of the arm and against the shoulder a and the edge a which bears against the boss F of the center post.
Some parts of my invention may be used without the others. Thus,in some instances, I prefer to use a flat arm having its edge bearing against theheadand hinge block, instead of the double-sided arms shown herein.
The meeting ends of the central posts A and B are flared outward, forming annular rims or shoulders, which serve'to strengthen this portion of the posts and also to permit the sections to be connected together by means of a spring-catch H, secured at one end to-one post and curved at its other end so as to clasp the adjacent shoulder of the posts and secure them together.
\Vhat I claim is- 1. 'In a camp-stool, the combinatiomwith a central post, of a socket-head provided with a cured to the bolt G by means of an engaging a ICIO 7 central boss and curved transverse grooves, a
series of swinging arms having their ends journaied in said grooves, and a hinge-block ad ustably' secured to said boss so as to bear against the inner edges of said arms, substantially as shown and described.
2. In a camp-stool, the combination,with a central post, of a socket-head provided with a central boss and curved transverse grooves, a series of swinging arms having their curved upper edges journaled in said grooves, and a hinge-block secured to said boss so as to bear against the inner edges of said arms, substantially as shown and described.
3. In a camp-stooh'the combination,with a FREDRIC O. LOVEJOY.
