IMPROVEMENT IN RECLlNlNG-CHAIRS.
Specification forming part of Letters Patent No. 159,395, dated February 2, 1875; application filed November 13, 1874.
Figure lis a longitudinal section through the chair-arm. Fig. 2 is a side elevation. Fig. 3 is a transverse section through one of the arms.
Similar letters indicate corresponding parts.
The invention relates to a chair the back of which is hinged, and capable of being inclined by the action of the chair-arms, which are made in pieces that slide upon each other, are subjected to the action of a spring having a tendency to draw them together, and are combined with a spring-lever, by means of which they are locked in position.
My invention consists in a peculiar connection ofthe pieces of the arm with each other and with the back of the chair, and in the means for locking the pieces, whereby I am enabled to produce a chair of greater comfort, beauty, and strength.
The arms are constructed of an arm-piece proper, which is connected to the back of the chair, and of a guide-piece, which is fixed to the chair frame, the arm-piece being fitted upon the guide-piece, in such a manner that when the pieces are drawn out, in order to inoline the back, the condition of the arm-piece remains the same, and by this means the comfort of the occupant is insured, while I am enabled to upholster the arm-piece, whereby the appearance of the chair is materially improved. lhe arm-piece is connected to the guide-piece by means of a strap secured to the former, and which embraces and slides on the latter. The
. guide-piece is provided with a cavity to receive `a spring or lever, by means of which the armpiece is locked in position, the lever being provided with a pin, which catches in one of a series of perforations formed in the strap of the arm-piece, and being operated by an exterior ornamental button, in such a manner that the working parts of the lever are concealed, the strength of the arms is preserved, and a more neat and eleganty appearance is given to the ch air.
In the drawing, the letter A designates the bottom frame of my chair, and B the back, which is hinged to the bottom at a. On the opposite sides of the back B I form lugs or projections C, to which the arm-piece D is connected, the connection being' effected through a pivot, b. E designates the guide-piece of the chair-arm, whichVV is fixed and supported by vertical branches F of the chair-frame. The armpiece D occupies the uppermost and rearmost position of the two pieces D E, being litted on the guide-piece E in such a way as to slide on it. 'When the pieces are drawn out, in order to incline the back, the arm-piece D remains unchanged, except in position, and the arm of the occupant, which necessarily is brought on the arm-piece D,.is not liable to encounter any ragged or angular edges, and an exceedingly comfortable chair is obtained. By reason thereof, also, the arm-piece D may be upholstered. The two pieces D E are connected together by a strap or sleeve, G, which is secured to the arm-piece D, and loosely embraces the guide-piece E. llhe guide-piece E is provided with a longitudinal groove, H, containing a coiled spring, I, and the arm-piece D is provided with an abutment, J, which is subjected to the action of the spring. When the arm-piece D is allowed to follow the action of the spring I it is drawn toward the fixed or guide piece E, and thereby the back Bis brought into a vertical, or nearly vertical, position. The arm-pieceD is made with a shoulder or stop, D', which serves to regulate its extent of motion. When the arm-piece D, on the other hand, is pushed back against the action of the spring I, the back B is inclined, and the arm-piece can be locked so as to retain the back in any desirable position by an elbowlever, K, provided with a pin, o, which catches in one of a series of perforations, d, formed in the strap G of the arm-piece. `The strap G, therefore, not only serves to connect the pieces D E together, but at the same time obviates the necessity of perforating the arm-piece. The elbowlever K is situated and works in a cavity, L, formed in the front end of the guidepiece E, and opposite the adjacent support F.
The lever is pivoted on the edge of the cavity L, and within the cavity is placed a spring, e, in such a position as to bear on the inner end of the elbow-lever K, and keep its pin in engagement with the perforations d in the' strap oil the arm-piece. lhe inner end of the lever K is connected to a button or rosette, M, Fig. 2, situated on the exterior of the guide-piece E, the shank of the button extending through a slot formed at that point, so that the shank may be secured to the lever, and so that the button may be raised and lowered. ,By raising the button M the inner end of the elbowlever K rises with it, and the pin c is ldisengaged from the perforation in the straprG, and the arm-piece D, following the action of the spring I, slides forward on the guide-piece.
By my arrangement the main or working parts of the lever K are concealed, while the button M, by means of which it is operated, forms an ornament to the chair, the arm and guide pieces remain intact, and the strength, as well as elegant appearance of the arm, is preserved.
What I claim as new, and desire to secure by Letters Patent, is
l. The elbow-lever K, having its short arm provided with a sliding exterior push-button,
M, and its long arm with pin a c, in combina tionwith the perforated strap or sleeve G, recessed guide-piece E, arm-piece D, having an abutment, J, fitting within in the recess in the guide-piece, and a coiled spring arranged within the latter, substantially as herein described. 2. rEhe combination, with the arm-piece D,
recessed guide-piece E, and coiled spring I, of i the strap or sleeve G, secured to the arm-piece,
and embracing the guide-piece, and provided with a series of openings, d, for the reception of a locking-pin, substantially as described, for the object specified.
3. The guide-piece E, having at one end a cavity, L, provided with an elbow-lever, K, f
