MARTIN FAAS, OF NEW YORK, N. Y.

ATTACHMENT FOR RECLININGI-CHAIRS.

Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed January 11, 1905. Serial No. 240,603.

To all whom it may concern:

Be it known that I, MARTIN FAAS, a citizen of the United States, residing in the borough of Brooklyn, in the county of Kings, in the city and State of New York, have invented certain new and useful Improvements in Attachments for Reclining-Chairs, of which the following is a specification.

This invention relates to attachments for such chairs as have hinged backs and means for supporting the backs of the chair at different angles; and the object of the present invention is to provide an attachment whereby the angle of the back may be varied and the back supported in the position desired, the device being conveniently operatable by a person while sitting inthe chair.

In the accompanying drawings, which illustrate an embodiment of the invention, Figure 1 is a side elevation, partly in vertical section, of a reclining-chair provided with the attachment. This view is on a relatively small scale. Fig. 2 is a fragmentary plan view of a part of the chair on a scale double that of Fig. 1 and illustrating the application of the attachment. Figs. 3, 4, and 5 are views of the attachment detached and on the same scale as Fig. 2. These comprise, respectively, an inner face view, an outer face view, and a rear edge view. Figs. 6 and 7 are views on a scale double that of Figs. 2 to 5, the former being a face View of the spring-casing and the sheave therein as it appears when the front plate is removed and the spring lifted out and the latter being a mid-section in the plane indi cated by line 012 in Fig. 3.

In Figs. 1 and 2, which show parts of a reclining-chair, A designates the front legs; B, the rear legs; C, the bottom or seat frame; D, the near arm partly broken away; D the opposite arm, and E the back, hinged at a to the seat-frame in a known way. This form of chair is known, and the present invention is not limited thereto. The chair shown is merely employed to illustrate the application of the attachment for adjusting the back and supporting it at the angle set. This attachment will now be described, premising that there will be one of these devices at each side of the chair or one at each arm of the chair, as herein shown.

In Figs. 1 and 2 the attachment as a whole is designated by F and is represented as secured to the under side of the fiat arm D by screws or other means.

Referring now particularly to Figs. 2 to 7,

1 designates a metal spring-case, preferably of cylindrical form and having an attachingplate 2, which may be provided with suitable holes to receive the securing-screws. This case has a removable front plate 3, which may be secured in place by screws, one of which is seen at 4 in Fig. 7, screwing into a lug on the front plate. Within the case, as seen in Fig. 7, is a spring 5, similar to a clockspring, secured at its outer end to the case by a screw 6 or in any other suitable manner and at its inner end to a spring-arbor 7 This arbor has a bearing at 8 in the case and at its other end a bearing on a stud 9 on the front plate 3. About the spring is a band 10, which limits the extent of its expansion and facilitates assembling the parts. On the inner end of the arbor 7 is a square 11, which engages a square aperture or hole 12, Fig. 6, in a sheave 13, to which is secured one extremity of a flexible connector 14, which may be a cord or chain, but which is here represented as a flexible-wire cord. This connector or cord is secured at b to the sheave and extends out through an aperture 15 in the casing (seen in Figs. 4 and 5) and thence to the back E of the chair, where it is secured in any convenient manner. As herein shown, there is a rod 16, which passes through the side stiles of the chair-back and the two connectors are coupled to the respective ends of this rod by end pieces 17, Fig. 2. In the sheave 13 are boltsockets 18, (three, equally spaced, are seen in Fig. 6,) and these are adapted to be engaged by the extremity 19 of a d-shaped lockingbolt 19, so as to hold the sheave 13 against rotation. This bolt 19 is slidably mounted in a bearing 20 on the side of the spring-case, and its extremity 19 plays through a hole in the fixed outer end of the spring-case, which hole comes into register successively with the sockets 18 in the sheave 13 as the latter rotates. A spring 21 on the bolt tends to press the bolt into a socket 18, and a button or thumb-piece 22 on the bolt enables the operator to press on the bolt for disengaging it from said socket.

It will be understood without minute explanation that the two devices E at opposite sides of the chair will be rights and lefts, so that the thumb-pieces or buttons 22 of the devices will be presented inward or toward each other. In other respects the devices will be identical.

The operation will be readily understood. The strong spring 5 in unwinding winds up IIO the connector 1 1. If the person sitting in the chair Wishes to give the back of the chair a greater inclination backward, he presses against the chair-back by leaning backward and then presses on both of the thumb-pieces 22 until the bolts 19 are disengaged. The connectors 14 will now be drawn out as the chairback recedes, and the sheaves 13 will be rotated until the bolts snap into the next sockets 18. The chair-back may be brought to a less-inclined position by the same operation, except that the pressure on the chair-back Will then be so regulated that the springs 5 may be able to overcome it and draw up the chair-back to a more nearly erect position.

The spring-arbor 7 may have in it a square keyhole 23 (seen in Fig. 41) to apply a key for Winding up the spring.

It will be noted that the function of the springs 5 is not to hold the chair-back in position, but to bring it to a substantially erect position when desired. The bolts 19 lock the sheaves 13, and thus limit the further inclination of the chair-back.

The attachments will be mounted an any convenient part of the chair other than the adjustable back, and as these chairs have arms it is convenient to mount them on the arms.

By reclining-chair is herein meant any chair with an adjustable back the inclination of which may changed.

Obviously there may be any desired number of bolt-sockets 18 in the sheave.

Having thus described my invention, I claim- 'In a device for the purpose specified, the combination with the case 1, provided with an attaching-plate and a removable front plate, of the socketed sheave 13 in said case, the flexible connector secured at one end to said sheave and extending out through an aperture in the case, the spring-arbor 7 mounted rotatably in the case and carrying said sheave,

' the spring 5 in the case and about said arbor,

the \J-shaped bolt 19, mounted slidably on the case and provided with a spring 21 and button 22, the operative end 19 of said bolt playing in an aperture in the case and adapted to engage the sockets in said sheave for locking the latter against rotation.

In witness whereof I have hereunto signed my name, this 5th day of January, 1905, in the presence of two subscribing witnesses.

MARTIN FAAS.
