I CAMP STOOL.
Application filed February 14, 1922. set-m1 no. 536,424.,
To all whom it may concern:
Be it knownthat we, ALFRED E. GAU- DREAU, RICHARD J. GAUDREAU, CrrAuLns D. GAUDREAU, and Lao H. GAUDREAU, citizens of the United States of America, residing at Springfield, county of Hampden, and State of Massachusetts, have invented certain new and useful Improvements in Camp Stools, of which the following is a specification. This invention relates to improvements in camp stools and particularly it is an improvement 011 theconstruct-ion shown,'described, and claimed in part in our prior Patent No. 1,408,581, March 7, 1922.
Broadly the invention comprises means for rigidly retaining the supporting legs in their open position which in general includes a slidable rod mounted in the supporting post having a thread at its lower end for receiviiw two lates for clam in the inner ends of the leg supporting braces bet-ween plane passing through the axis of the supporting post showing two of the legs in open and supporting position and the means for locking the braces thereto for retaining thelegs in their supporting position.
Fig. 2 isa-plan view on the line 22 of Fig. 1 looking in the direction of the arrows and showing the upper edges of the leg retaining braces and the lowerendof the slidable rod in section, and g I Fig. 3 illustrates the frlctional device for retaining the slidable rod in either its; in- 1 ward or outward position in the'post member.
V Referringto the drawings in detail:
1 1 designates the tubular post member which supports the seat member at its up per end, and to the lower end of which are pivotally connected the supporting legs 2, by means of the ears 3 and the pins 4. mounted inthe post 1 is the rod 5. This rod is formed with a groove 6 and in this groove is located. the spring 7 one end of which is bent and inserted in the opening 8 so that normally its upper end springs out ward and engages the inner surface 9 of the tubular member 1 for frictionally holding Slidably the lower end o'fthe tube 1 which enters the groove 6 and engages a pin 11 on the rod 5 for limiting the outward movement of the rod The lower vend of the rod 5 is threaded as indicated at 12. Rigidlyse cured to the lower end of the rod isa plate" 18 by means of the rivet-ed head 14. This plate is formed with slots 15 cut in the outer edge and another set of slots" 16 which are located in the same line as the slots 15 but nearer the center. "These fslots are for the purpose of receiving the inner endsof the leg retaining braces 17 which braces are formed wlth a hookshaped end 18 which enters the slots 16 of the plate13 while the portion 17 of the braces immediatelyback of the hook s 1S enters the edge slots 15 of the plate 13. These'braces are-pivotally connected to the legs 2 as indicated at 19 and located on the threaded part 12 of the rod 5 above the plate 13 is the plate 20, which Y after the inner ends of the braces 17 are connected to the plate 13 placing the hookshaped ends 18 in the slots 16 and the part 17 in the slots 15 is turned down on they thread 12 and engages the upper edges of the'braces 17 as shown in 1 thereby rigidly retaining the braces 17 in their sup porting or holding positions. When the legs are to be folded the plate 20 is threaded up or turned on the threads 12 and the braces are then removed from the slots 15 and 16 and folded into the legs 2 asindicated by the dotted line 21. After the braces 17' are folded the rod- 5 is pushed into the tubular member 1 and is frictionallyretained in its inward position by means of the springs 7. From this description it will be seen that we have provided avery simple and rigid means for retaining the braces 17 which support the legs of the camp stool in a rigid and permanent manner and one that will not become unlocked after the braces are retained in their locked position.
It is to be understood that we do not limit ourselves ,to any particular form of fric tionaldevice for holding the rod 5 in its inward'or outward position, and that shown is merely illustrative. j I a e It will be seen that the braces 17 by means designates the position of the plate 20 when the braces 17 are inserted and removed.
. The pin 11 limits the downward movement of the rod 5. I It should be particularly observed that the pin 10 in the groove 6 in the rod or plunger 5' accurately maintains the position of the slotted plate13 whereby'the slots in this plate willalways be in alignment with the braces 17 The pin 11 is so placedthat the downward position of the plate 13 brings the braces in ahorizontal plane. I The braces I? after being removed from the plate 13 are drawn away by the legs 2 and then folded into the legs as shown in dotted lines.
What we claimis: I
V In a camp stool construction, the combinationwith a supporting post member, of
a member slidably and frictionally retained therein, legs pivotallyconneoted to the supto the legs" for retaining the legs in their ortin oost member brace meansconnected supporting position, interlocking connection between the slidablemember and the inner ends of the leg supporting braces, said means including a pair of clampmg members on the slidable member for engaging the inner ends of the leg supportlng'braces, one of the clamping members being fixedly secured to the slidable member. v
2. In a camp stool construction, the combination, of a supporting post, legs p-ivotally connected thereto, braces for retaining the legs in their supporting position, means for,
a retaining the inner ends of'the braces in their operative position, said means includlng a parrot plates for clamping the nner fonds of the braces therebetween, a rod slidslidable member, a supporting post in which ably mounted in the inner ends of the-supporting post on which the plates are located and between which the braces are clamped.
3. A locking device for the leg braces of a camp stool comprising in combination, a
said Inemberis located, of a plate secured to said member and formed with aplurality of' slots to receive the inner ends of said braces f and a second plate threaded on the member engaging the upper edges of the braces for clamping the braces to the fiXGCl plate, as
4. A rod for retaining the leg braces of a camp stool in their supporting positions, atubular post, said rod having means -for frictionally retaining the same within the post, and means at its lower end for clamping the .upper'and lower edges of the inner ends of the braces.
In a camp stool, the combination, of leg supporting braces, said braces having hook-shaped inner ends, a rod, a plate secured thereto and formed with slots to receive the hook-shaped ends and also the portion of the braces immediately back of the hook-shaped ends and a second plate on the 'rod for clamping the inner ends of the braces to therod.
(3. In a camp stool construction, the combination with the supporting post, of a threaded rod slidable therein, supporting legs connected to the post, braces connected to the legs and formed with attaching devices, two plates on the rod, one being slotted and fixed to the rod for receiving the at- I attached thereto, a rod slidable in the post,
and frictionally retained therein, said rod having a plate secured thereto and'formed with slots, leg supporting braces having hooks which are adapted to enter the slotsand a second plate on the rod for clamping the braces in the slots, said braces being prevented from ha-ving'lateral and'vertical motion when so clamped in the slots, as described. v
