JOHN DAVID BROWNE, OF NEW YORK, N. Y.

COMBINED BOOKING AND CASTER CHAIR.

Specification of Letters Patent No. 964, dated October 5, 1888.

T0 all whom 'it may concern Be it known that I, JOHN DAVID BRowNE, of the city, county, and State of New York, cabinet and chair maker, a native of Great Britain, but having resided more than two years in these United States, and having duly declared my intention to become a Citizen thereof, have invented and made and applied to use certain new and useful Improvements in the Mechanical Construction of Chairs, which produce what I designate as a Combined Rocking and Caster Chair, for which I seek Letters Patent of the United States, and that the said improvements and the methods of constructing and using the saine are fully and substantially set forth in the following description and in the drawings attached to and making a part of this specification, whereinF Figure 1 is a representation of a chair fitted with said improvements and resting on the four legs and casters with the rockers off the floor. Fig. 2 is a chair with the back legs turned up under the chair and resting on the rockers. Fig. 3 is a back view of a. chair with back legs down. Fig. 1 is a view of the back legs shown as detached from the chair as the same are fitted by me to turn up under the chair as hereafter described. Fig. 5 is a side view of the back legs with a handle or lever fitted to turn them, and the same letters as marks of reference apply t0 the same parts in all the several figures.

A is the back framing of a chair to which the legs B are attached by the cross shaft B1 and turn 0n the bearing plate b and framing at c. The back legs B are to be made of iron or any other material to which casters or rollers may be att-ached at d.

C is a handle or lever fitted to the shaft B1 as shown in Fig. 5 to raise the legs as shown in Fig. 2, and let the chair fall back or down on the rockers R by turning the handle C upward from D to H as in Fig. 2.

D is a notched plate fitted on one side of the chair into which the handle C catches to retain the legs B in avertical position.

Fig. G is an enlarged side view of the handle C.

Fig. 7 is a side view of the plate D. m` is a stop to prevent the handle C from turning downward when converted into a rocking chair. R are the rockers framed into the front legs M and back legs at A and hollowed in front as at L to allow of the caster revolving.

To use the chair as a rocking chair turn the handle C up to H as in Fig. 2, Which turns the back legs under and lets the rockers come in contact with the floor. To use the chair on the legs turn the handle C down to I into the plate D, Fig. 1, the handle being sprung in or out of the catches by the hand operating on it as on a spring.

I do not confine myself to the particular material or fashion or shape of the legs, or any particular kind of caster or rollers, or any particular description or fashion of chair because all or any of them may be varied to suit personal tastes or Wishes.

I do not claim to have invented any of the parts above described, the same separately laken being well known-but I claim as my invention for which I seek Letters Patent as not having been previously so used- The combination of the cross shaft and movable back legs with the hand lever in the simple arrangement or form herein substantially described and set forth, by which a rocking chair may be immediately converted into a caster chair, or the reverse, and thus afford both descriptions of Convenience at a very moderate expense.

In witness whereof I have hereunto set my hand in the city of New York on the fifteenth day of June one thousand and eight hundred and thirty eight.

JOHN D. BROVVNE. [1.. s]
