Letters Patent No. 98,86%, dated January 18, 1870.
The Schecuie referred to in these Letters Patent and making part of the same.
Taall whom it may concern:
Be it known that I, JAMES G. HOLMES, of Charleston, inthe district of Charleston, and State of South Carolina, here invented a new and improved Stop for the Hinged Frames ot' Reclining-Chairs; and I'do hereby declare that`thetbllowing is a t'ull, clear, and exactdescription thereof, reference being had to the accompanying drawings, making part ot' this specicat-ion, in whichl 1-`igure 1 is a perspectivev view of a hinged chair` frame having my invention applied to it.
Figure 2 is a side viewof the same.
Figures 3 and 4 are sectional views, showing the construction of the stop. t
Similar letters of reference indicate corresponding parts in'the several figures.
This inyention relates to an improvement on that class of chairs which have their backs, seats, arms, and foot-boards connected together by'means ol' nietallic""quadra.ilgular hinged frames, so'that a person can either sit erect, or incline at any desired angle.
vThe nature of'iny invention consists in applying to the said hingedlnetallie frames diagonal braces and cam-stops, in such manner, that by a very simple manipulation, the jointtd parts ofthe chair can be rigidly locked at any desired angle, as will be hereinafter explained.
As the-reclining'or therapeutic chairs lto which my in'i'provement relates are so well known, I have only represented in the accolnpanyiin,r drawings one of' the jointed frames to which `the arms, backs, seats, and loot-boards of such chairs are secured. I1`his frame, shown in figs. 1 and 2, is colnposed of two longitudinal parallel pieces, A A., connected, by joints a a, to short end pieces B B, from which project the pivots?) b. This is the well-known form of quadrangulartrame used in the construction of the chairs in question.
To the bottoni side of the top piece A, a plate, d, is rigidly secured; and tothis piece,a. brace-rod, C,` is hinged, at c.
This brace-'red extends forward and downward a. suitable distance, and is pivoted, at e, to a sliding strip, F, the forward end of which is turned up, at f.
The strip F lies flat upon the upper side of the bottom piece A ofthe hinged frame, and is allowed, when not locked, to slide longitudinally thereon.
The length ot' this sliding strip F should be such as to allow all the required movements to he givento the chair-sections, and also to allow the chair-sections to be adjusted to thev different angles required.v
Two upright hearings?) i, are rigidly secured to and rise'above the edges ot' the'bottoin piece A, between which slides the piece F.
These bearings have applied to them a verticallymovable piece, h, the ends of which are forked, so as to be held in place between the bearings; and above thispieceh is a cam, g, which is pivoted to the transverse pin n, so as to rock freely thereon.
-Thisgcam g'has a. flattened extension or handle, G, formed on it, by which it is adjusted.v
By depressing the handle G, as shown in tig. 3, the cam g will forcibly press .down the plate h upon the sliding piece F, and thus rigidly lock and hold this piece in place upon the traine-strip A.
By raising the handle G, the cam g will release the plate h from the slide F, and, by thus relieving the slide,l allow the frame to be tlexed about its joints.
, 1t will be seen that the plate 71., which is applied between the cam g and the slide F, receives directly upon it the perimeter of this cam, and affords a wide beariug-sln'tace upon the said slide, and :a much wider bearing-surface than would be atlbrded by the cam alone.
Having described my invention,
flint I claim as new, and desire to secure by Letters Patent, is-
Iu combination with the hinged fram-e of a reclining-chair, the diagonal brace C, slide F, movable plate h, and 'rocking can) g, substantially as audl'or the purposes described.
` JAMES G. HOLMES.
