vSpecicaton of Letters Patent.

Application filed March 16, 1914. Serial No. 825,046.

To @ZZ whom t may concern Be it known that I, DE VATT PEPPER, a citizen of the United States, residing at New Milford, in the county of Litchfield, State of Connecticut, have invented certain new and useful Improvements in Adjustable Chairs; and I dio declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the subject of chairs and has particularly in view improvements in chairs of the adjustable seat and back type.r

The primary aim of the invention is to produce a chair in which the back and s eat have a simple and practical c onnection whereby the lower end of the back and the rear end of the seat are at all times retained in such relative positions that ythe upholstery carried by the said seat and back' willvbe in intimate contact of such a nature as to cause the upholstery of the back to be buried in the upholstery of the seat and thereby make the upholstery of the back and seat practically c ontinuous.

A simple and preferred form of the in-V vention is shown in the accompanying drawings, wherem- Figure l is a view in side elevation of the improved chair, showing the back in an upright position and with part of the supporting frame broken away to show the connection between the back and seat. Fig. 2 is a similar view, the back being inclined. Fig. 3 is a view in rear elevation.

The improvedchair in so far as the sup` porting frame and specific type of back and seat are concerned, may be of any preferred type. In the drawings, the supporting frame shown has been designated in its entirety by the numeral 1, and the seat 2 has the lower edge of its front portion hinged' or otherwise pivotally connected to the front rail of the supporting frame, as indicated at 3. The seat 2 as shown, is provided with an extension foot-rest. The rear posts of the supporting frame l are provided with brackets il equipped with journals 5 for the reception of the pivot rods 6 that project laterally from intermediate portions of the side bars of the back 7. Plates 8 are pivoted to the brackets e and have base flanges 9 adapted to be'swung over the journals 5 and thereby prevent accidental displacement of the pivot rods 6. The lower end of the back Patented Jan. 19, 1215.

7 projects between the rear posts of the supy porting frame 1 over the rear end of the seat,

2, and the side bars of said back have their lower end portions equipped with laterally projecting pivots 10 upon which the upper ends of links 11 are mounted. The lower ends of the links 11 are jointed to the upper ends lof links 12, the links 12 having their lower ends pivotally connected to the rear end portions of the side bars of the seat 2.

As described, it will be seen that the back '7 has intermediate pivotal connections with the supporting frame 1, and kthat the only connection the seat 2 has with the supporting frame is the front pivotal connection 3, the back 7, through the

links

11 and 12 forming the rear support for said seat. As aforesaid, the lower end of the back 7 overhangs the rear of the seat at all times, and this relative disposition of said parts, causes the lower `end of the upholstery A of the that it not only materially contributes to comfort, but also prevents the creating of drafts of air, as well as preventing articles occupant, falling to the floor.

The operation of the chair is indicated in the drawings and from the same it will be observed that by lowering the back 7, the

links

11 and 12 are caused to elevate the rear end of theA seat 2, and simultaneously cause the lower end of said back 7 to swing in over the seat 2. A locking plate 13 equipped with an end cam 14 may be pivoted to one of the links 11 and engage the pivot 10 thereof to lock the back in the desired position. j

Incidental details of the chair are shown in the drawings, such as an abutment 15 seat to its lowered position, but it will be understood that such details may be varied or omitted. y

l i placed on the seat for the convenience ofthe l What l claim as my invention is l. ln a chair, the Combination of a stationary supporting frame, of a seat provided with a cushion having its forward end hinged to the forward end of the frame, a back-rest provided with a cushion having intermediate portions of its sides pivotally connected to the rear of the frame and its lower end projecting over the rear end of the seat, and jointed link connections between the lower ends of the sides of the back-rest and the rear end of the seat for holding the lower end of the back-rest cushion in intimate Contact with the upper surface of the rear end of the seat cushion.

ln a chair, the combination of a stationary frame, of a seat therein and having its forward end hinged to the forward end of the frame, said seat being provided with upholstery, a back-rest having intermediate pivotal connections with the rear of the frame and provided with upholstery, and a pivotal connection between the lower end of the back-rest and the rear end of the seat for supporting vthe rear end of the seat and for Constantly retaining the upholstery of the back-rest andthe upholstery of the seat in buried Contact.

3. ln a chair, the combination of a supporting frame, a seat having its forward end pivotally supported by the front of said frame, said seat being provided with upholstery, a back-rest having intermediate pivotal connections with the rear of the frame and having its lower end projecting over the seat, said back-rest being provided with upholstery, and means Connecting the rear end of the seat with the lower end of the backrest for constantly retaining the lower end of the back-rest upholstery buried in the rear end of the seat upholstery.

A. A chair comprising a supporting frame, a seat having a front hinge connection with the front of the frame, a backrest having an intermediate pivotal. connection with the rear of the frame and its lower end projecting over the rear of the seat, links pivoted to the lower ends of the sides of the back-rest, and links having direct pivotal connection with the first-inentioned links and pivotally connected to the rear of the seat.

5. A chair comprising a supporting frame, a seat having a front pivotal connection with the front of the frame, a backrest having intermediate pivotal connections with the rear of the frame, and means pivotally connecting the lower end of the back-rest with the rear of the seat and forming a support for the rear of the seat and for constantly holding the lower end of the back-rest over the rear of the seat.

6. A chair comprising a supporting frame, a seat having a front pivotal connection with the front of the frame, a back-rest having intermediate pivotal connections with the rear of the frame, jointed link connections between the rear of the seat and the lower end of the back-rest, and means carried by one of the links for engaging the connection between the links to lock the back-rest against movement.

7. A chair comprising a supporting frame, a seat having a front pivotal connection with the front of the frame, a backrest having intermediate pivotal connections with the rear of the frame, pivots projecting laterally from the lower ends of the sides of the backrest, links mounted on the pivots, links pivotally Connected to the rear of the seat and jointed to the first mentioned links, and a looking plate pivotally mounted on one of the back-rest links and having p nlend cam for engaging the pivot of said ln testimony whereof I ailiX my signature in presence of two witnesses.
