    N° 22,360 A.D. 1904 * Date of Application, 17th Oct., 1904—Accepted, 19th Jan., 1905 COMPLETE; SPECIFICATION. An Improved Appliance Comprising a Water Motor and a Spittoon for Attachment to Dental and like Chairs.” We, William Baskin Alford and Edwin Pllmer Alford both of Sumter, Sumter County, in the State of South Carolina, United States of America, Dentists, do hereby declare the nature of this invention and in what manner the same is to be performed, to be particularly described and ascertained in and by 5 the following statement; This invention relates to* combined dental water motors and spittoons, and supporting standards therefor, and has for its object to provide a construction in which the supporting standard for the water motor will be formed by one- of the water pipes thereof. 10 A further object is to conduct the water from the motor to* the spittoon, so that the same water is used for both. A further object is to* provide a structure/supported on a chair, carrying a motor, a spittoon, a drinking glass, and cocks for supplying water thereto, and containing places for the attachment and convenient manipulation of various 15 other devices used in dental operations, the intent being* to support, in a con¬ venient position and advantageous manner, most of the appliances needed by a dentist in connection with the chair. The invention is illustrated in the accompanying drawing which is an elevation of the apparatus, with parts in section. 20 Referring specificially to the drawing, 6 indicates a supporting arm for the apparatus, and it is bolted to the bottom of the chair as indicated at T, and projects therefrom conveniently from the left side of the chair. At the end of this arm is a sleeve Ga through which a waste pipe 8 extends, leading from the spittoon 9. The waste pipe supports the spittoon and the motor and its con- 2.*> needed parts, and is free to turn in the sleeve. It is supported by a collar 8a adjustable as to height by set screw 8b. The motor is indicated at 10 and its waste pipe 11 leads to a tubular rim 9a of the spittoon, and the waste water from the pipe escapes through a slit 9b produced between the edge of the rim and the bottom of the spittoon. The waste pipes. 8 and 11 are bent to project horizontally 30 to support the spittoon at a proper position to be accessible to the occupant of the chair. The waste pipes are of metal, and formed, in connection with a stay rod 12, a standard which supports the motor, the spittoon, and the various other parts, as such may be turned in the sleeve of the supporting arm to bring the device in proper and suitable position for use, as occasion demands. 35 The motor includes a reversible wheel 10a driven by a jet from either of the pipes 18 which are connected to rubber supply pipes 14 leading to a valve casing 15 at or about the floor. The flexibility of these pipes permits the necessary turning movement of the supporting standard. The pipes 18 are fitted with stop-cocks 13a, and also with bib-cocks 13b one of which will supply water to a 40 glass 16 held in a bracket IT clamped on the waste pipe 11. The other bib¬ cock may be used to supply water to a hose and .syringe, for cleaning cavities, and the like. The pipes 13 are joined and held in position by a cross bar 18. [Price
