SPECIFICATION forming part of Letters Patent No. 762,512, dated Jane 14, 1904.
Application filed January 6,1904.
To all whom 7125 may concern:
Be it known that I, WILLIAM A. BUssE,.a citizen of the United States, residing at 118 North May street, Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Chairs, of which the following is a specification.
My invention relates particularly to chairseats; and my primary object is to provide a readily-removable seat of exceedingly simple and inexpensive construction which is adapted to use in connection with seat-frames having different-sized openings. 7
The invention is illustrated in the accompanying drawings, in which- Figure 1 represents a top perspective view of a seat and the frame to which the same is applied; Fig. 2, a bottom perspective view of the same, and Fig. 3 an enlarged sectional view taken as indicated at line 3 of Fig. 1.
A represents a seat-frame having a plain top surface a and a plain bottom surface a, B a removable seat having its lower marginal surface resting upon the upper surface of the frame A at the margin of the opening a of the frame, and C retainers pivotally connected with the bottom of the seat near the four corners of the same and engaging the adjacent portions of the lower surface of the frame A. The margin of the bottom surface of the seat overlaps the inner margin of the top surface. of the seat-frame, so that the bottom of the seat-frame is at some distance beneath the bottom of theseat itself. The retainers C are preferably stamped from sheet metal possessing a certain amount of springiness, and the retainers are preferably ofapproximately hook shape.
In applying the seat to its frame the hooks are turned on their pivots so that they will lie within the opening a of the frame, and the hooks are then bent downwardly and swung Serial No. 187,912. (No model.)
upon their pivots so as to engage the bottom of the frame in the manner shown. In forcing the hooks to the retaining position the -eient distance from the periphery of the seat to enable the seat to be applied to frames with different sized openings within reasonable limits. The hooks are arranged in pairs, with oppositelyedirected tongues, as appears from the drawings The means for connecting the seat to the frame is exceedingly simple and inexpensive and perfectly adapted to its purpose, serving to anchor the seat securely. Each hook is preferably provided with a small knob 0 which serves as a means for grasping or engaging the hook to force the same to the retaining position.
What I regard as new, and desire to secure by Letters Patent, is
1. The combination of a suitable seat-frame, a removable seat resting thereon, the lower surface of the frame being at a distance below the bottom of the seat and bent hook-form s'pringy retainers pivotally connected at their base ends with the bottom of the seat and having the tongues of the hooks bearing beneath said frame.
2. A seat having pivotally connected with the bottom surface thereof hook-form retainers, arranged in pairs, the tongues of the members of each pair being turned in opposite directions, for the purpose set forth.
WILLIAM A. BUSSE.
