UNITED STATES PATENT OFFICE.
HENRY DAVIDSON PLIMSOLL, OF NEW YORK, N. Y.
WINDOW-CHAIR.
SPECIFICATION forming part of Letters Patent No. 423,698, dated March 18, 1890.
Application filed August 12 1887.
.To all whom it may concern:
Beit known that I, HENRY DAVIDSON PLIMsOLL, a subject of the Queen of Great Britain and Ireland, and residing at the city of New York, in .the county and State of New York, have invented a new and useful Chair, of which the following is a specification.
My invention relates to improvements in chairs, whereby they can be adjusted and fastened to the sills of windows; and the object of my improvements is to contrive and provide a safe and convenient seat for persons while engaged in cleaning the Windows This work is, as a rule, now done in an awkward, inadequate, and dangerous manner. The cleaner sits upon the sill of the window, having the greater part of his body on the outside of the window, which is lowered on his lap, there being no support for his back, so that he is compelled to make a continual effort to preserve his balance with the one hand, while at the same time cleaning the window with the other. This mode of operation is obviously not only inconvenient-and inadequate to the purpose, but is attended with great risk and danger to life and limb, which this invention is intended to, avoid. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a view in perspective of the chair, showing the seat closed. Fig. 2 is a view in perspective of the chair, showing the seat partly extended. Fig. 3 is a side elevation showing the chair placed astride of the sill of the windows, asit will appear when in use. Fig. A is a plan View of the seat inverted. Fig. 5 is a front elevation of the seat with the block, hereinafter described, fastened to it. Fig. 6 is a plan view of the seat.
Similar letters refer to similar parts throughout the several views.
In the drawings, Fig. 2 represents a chair similar to an ordinary chair without arms in all respects save the following: The seatA is split or divided at B into two unequal parts, to the large one of which 0 theback legs D E are fastened, the front legs F Gbeing fastened to the other part H. The dowel-pins I J are fastened to the part H by being driven into it, or by any other suitable device, and
Serial No. 246,812. (No model.)
are intended to run freely in and out of the holes K L, made in the part 0.
M is a screw, by means of which the part H is extended and closed, the part 0 being screw-threaded for the purpose of receiving the said screw. This screw is furnished with' the washers. N O, and the pins P Q, which are intended for the purpose of preventing the said washers from slipping upon the said screw and securing them. in place snugly against the part E, Fig. 6. A block of Wood R, Fig. 3, is fastened by means of screws or other suitable device to the seat, transversely across it on its under part and at its back. This block R is also seen fastened to the seat A at Fig. 5. The object of the. block is twofold first, to remove the weight and pressure of the body when in'the chair from that part of the sill upon which the seat would rest were it not for the interposition of this block and to limit and confine this'weight and pressure to that part only of the sill upon which this block actually rests; second, to prevent the chair from tilting backward upon the sill under the weight and pressure of the body when resting against the back of the chair, and to thereby reduce to a minimum the reciprocal pressure exerted by and between the legs of the chair and those parts of the sill against which they are screwed and upon which they impinge. i
The distinguishing feature of this invention is a vise, consisting of the combination of the split seat, the legs of the chair, the screw, and the block, of which vise the legs are the two jaws. Provided, therefore, that this feature be preserved, it is immaterial whether the seat be or be not split, or the legs be or be not fastened to the seat, or- 1n what manner they are so fastened, or whether a screw, or screws, or a block, or dowel-pins be or be not used. Other mechanical devices may be substituted for these parts or instruments forming this combination for the purpose of constituting and forming the vise herein described.
Having fully described my invention, what I desire to claim, and secure by Letters Patent, is
The hereindescribed chair, consisting of the combination of the split and extensible seat A, the back legs D and E, which are used as herein shown and described, and for 10 fastened to O, the larger part of said seat, the the purposes herein set forth. front legs F and G, which are fastened to H, In Witness whereof I have hereunto set my ghe 3113311163 part) ofksaiddseat,1 Elie dowel-plins hand and seal this 5th day of August, 1887. 5 an ,s i ing ac war anc orward Wit 1in I the holes K and L, made in the said larger H DAVIDSON LIMS OLL. [n s] part of the seat, the screw M, engaging with \Vitnesses: the said part 0, which is screw-threaded for H. O. MARVAL, I the purpose, and the block R, intended to be J H. LYNN.
