FOLDING CHAIR.
SPECIFICATION forming part of Letters Patent No. ?36,180, dated August 11 1903.
Application filed January 9, 1902. Serial No. 88,994. (No model.)
To all whom it may aoncern: y
BURN, of Baldwinville, in the connty of Worcester and State of Massachusetts, have invented an Improved Foldin g Chair,of which the following is a specification.
My invention relates to folding chairs; and it consists in improved nechanism for locking one pair of crossed legs to the chair-france.
In the drawngs, Figure 1 is a side View of my chair in its upper position. Fig. 2 is a side View in its lower position. Fig. 3 is a sectional View. Figs. 4, 5, and 6 are details described below.
The back, arms, seat, supporting-posts, and cross-pieces constitute the base A of my chair and are as usual in this class of chairs: The crossed legs B and D, pivoted at b, are as usual in this class of chairs, the legs B being pivotally connected to the cross-pieces of the base A atb', and the legsD with those cross-.
pieces by the links E, as usual. The pivotand-link connections allow the chair to occupy a lower position as a rocker and also a higher position as a .high chair; but when used as a high chair the upper end of the legs D must be locked to the cross-piece of the base A. A slot d on leg D and a pin d' on leg B act to limit the Upward movement of the parts when the legs B and D are at the proper angle for the high chair.
'Pivoted to each cross-piece -is a hook F, which engages a catch G on the upper end of leg D. Catch G may be prolonged to form a shoulder g, which will serve as'a stop when the legs B and D are brought to the proper angle for a high chair, serving the same function as the slot d and the pind'.
Connectingmthe hooks F is a round H, carrying a stop J, to which is pivotally connected a rod K, which passes through an eye Ic and is surmounted by a knobk'. Th e spring L tends to keep the chair locked by keeping the hooks F in contact with the catches G; but the roundH and ,consequently the hooks F are prevented from descending too far by the stop J, which is attached to the round H and which bears upon the round M.
It will be clear that When the chair is raised from the lower to the upper position the pin d' and slot d or the shoulder g of catch Gwilllimit the angular motion of legs B and D and the hooks F will engage the catches G and lock legs D to the cross-pieces. To lower the chair, the books F are disengaged from the catches G bya slight pull on knob 70', and the chair is then lowered into its 'ro cker form, Fig. 2.
What I claim as my invention is- 4 In a folding chair the combination of base A; links E; crossed legs B and D pivoted together,1egs B being pivotally connected with base A and legs D being connected with base A by links E; the hooks F pivotally connected to the chair-base; round H connecting the hooks; round M; stop J connected with round H and adapted to rest on roundM; rod'K for raising round H; catches G carried by legs D, and spring L for depressing round I-I', the hooks F engaging catches G and looking base A to legs D when round H is depressed by spring L and the chair is in its elevated position.
