Be it known that I, JOHN E. MORGAN, acitizen of the United States, resi-ding at Emporia, in the county of Lyon and State of Kansas, 3' have invented a new and useful Improvement f in Dental-Engine Attachments, of which the following is a specification. i My invention is in the nature of a dentalengine attachment designed to furnish a con- OI tinuous blast of air to blow the chips from the cavity of a tooth as fast as they are drilled,

an` aware that air-blast devices have been heretofore used in connection with a dental engine, and i do not claim this idea broadly.
Having thus described my invention, what I l. claim as new, and desire to secure by Letters Patent, is-
l. A blowing attachment for a dental engine, cannprising rotary fan having a central intake-opening and a tangential spout, a pulley arranged on the fan-shaft, means 'for supporting the attachment on the dental engine and operating it from the dental-engine belt and a hose and nozzle for carrying the ai r-blast substantially as described.
2. A dental engine comprising in its construction an upright standard, a shaft-support secured to its vupper ent, a rigid shaft jourualed in said support, a pulley tast on one end of the shaft, a flexible shaft operatively connected to the opposite end and a driving belt passing around said pulley; in combination with a rotaryr fan arranged in a plane parallel to that of the shaft-pulley and on the opposite side ol said pulley `trom the iiexible shaft, and a driving-pulley arranged on the iian-shaiit to bear against the dental-engine belt substantially as shown and described.
