S. LANGF-QRD. CHAIR SEAT. APPLICATION FILED SEPT. 4. 19:4. Patented Apr. 13, 1915. SIIVIEON LANGFORD, OF EVANSVILLE, INDIANA. CHAIR-SEAT. Specification of Letters Patent. Patented Apr. 13, 1915. Application filed September 4, 1914. Serial No. 860,271. To all whom it may concern: Be it known that I, SIMnoN LANGFORD, a citizen of the United States, and resident of Evansville, Vanderburg county, State of Indiana, have invented certain new and useful Improvements in Chair-Seats, of which the following is a specification. My invention relates to chairs and more particularly to seats for nursery and other chairs. The object is to provide such chairs with seats that are made so as to completely disguise'the real construction of the chair, and yet are simple and readily convertible. The above and other objects and the novel features of the invention will be apparent from the following description taken in connection with the drawing in which, Figure l is a perspective view of a chair embodying my invention showing a part removed and shown in perspective; Fig. 2 is a bottom plan view of the chair seat; and Fig. 3 is a transverse sectional view of the seat taken on the line 33 of Fig. 2. Referring to the drawing, 10 designates the seat of the chair which is provided with supporting legs, a back, and arms of the usual or any preferred construction. The chair seat 10 has a central opening 11 the upper edge of whichis rounded. Surrounding the opening 11 and in the top surface of the seat there is an annular groove 12 which has holes 13 and 14 therein on diametrically opposite sides of the opening 11 and extending through the seat 10 from the bottom of the groove 12 to the bottom surface of the seat 10. Three hooks 15 are spaced around the central hole 11 on the underside of the seat 10- and between the line oi. the groove 12 and said central hole 11. The hooks 15 are designed to engage the outer flange 16 of a vessel 17 and hold the mouth of the same against the under side of the seat 10 and in register with the hole 11. To completely cover the opening 11 and the mouth of the vessel 17 I provide a plate or sheet 18 ofwood, metal, paper or other material and resembling an ordinary chair bot tom. 1 An annular member 19 is secured to the bottom side of plate 18 and Within the marginal surface of the plate 18 will rest on the top surface of the seat member 10. Two hooks 20 and 21 having laterally extending bent ends are fastened in the lower edge of the annular member 19, and being threaded, are turnable to adjust the position of the lateral extensions at their ends. The hooks 20 and 21 are disposed so as to fit in and extend through the slots or elongated holes 13 and 14: respectively. The lateral extensions of the hooks are capable of being turned so as to engage the under side. of the seat 10 and lock the cover part in place and are also readily turnable so that the cover may be removed when desired. The imperforate plate 18 fits tightly against the top surface of the seat 10 and closes the opening 11, also overlapping the groove 12 and concealing it from view. Having described my invention what I claim as new and desire to secure by Letters- Patent is, 1. A chair seat comprising a member having an opening therethrough and a groove surrounding said opening, said groove having holes therein, a cover part for said open ing. a piece on said cover part and fitting said groove, and devices fitting in said holes and adjustable to lock said cover part in place onsaid member. 2. A chair seat comprising a member having an opening therothrough and an annular groove surrounding said opening, said groove having holes extending from the bottom thereof through to the bottom surface of said member, a cover member for said opening, an annular part on said cover member and fitting said groove, and devices on said annular part and fitting in said holes and readily adjustable to lock said annular part and cover member in place over the opening. 3. A chair seat comprising a member having an opening therein and a groove surrounding said opening, a cover part for said opening, means for securing the cover part In testimony whereof I afiix my signature in placlel olver Saki (fpeninlg corlnprising dig in presence of two witnesses. vices w 1c 1 extenr tn'on 1 Sillf move an engage the under side ot said m mber, and SIMEON LANGFORD' means for holdin a vessel in place against Witnesses: the under side 0?sa1d member in register ANNA MCCOOL, with said opening.
