UNITED STATES PATENT OFFICE.
MILTON H. KNAPP, OF ADRIAN, MICHIGAN.
JEWELERS WORK-BENCH.
SPECIFICATION forming part of Letters Patent No. 260,880, dated July 11, 1882. Application filed May 14, 1881. Renewed'd'anuary 14, 1882. (No model.)
To all whom it may concern:
Be it known that I, MILTON H. KNAPP, of Adrian, Lenawee county, Michigan, have invented an Improvement in Dentists or J ewelersBenches, of which the following is a specification.
The nature of this invention relates to certain new and useful iinprovementsin theconstruction of work-benches especially designed Beneath the top of the bench is a frame, F,
and in this frame is secured the bellows G, preferably of the form shown. One end of a cord or belt, I ,is secured to thelower bellows, which passes thence up and over a pulley, a, and down to the crank-arm E, to which its opposite end is secured.
A spring, J, is secured at one end to the lower bellows, its opposite end being secured to the frame of the bench or to the floor, as described.
A similar spring, K, is connected at one end to the upper bellows, while its opposite end is secured to the frame F or any other suitable portion of the bench.
By this construction and arrangement of parts I provide a means for operatingalathe, L, upon the top of the bench, if desired, by a belt from the pulley D; but when thus used the belt I should lie-detached from the crankarm E.
When it is desired to use the bellowsin connection with a blow-pipe, with which it may readily be connected by any proper means, the belt I is attached to the crank-arm E, when by rotating theshaft by means of the treadle G the belt I is caused to draw up the lower bellows, which forces its air into the upper bellows, the spring J drawing the lower bellows down, and so on, alternatelyinflating and expelling air into the upper bellows, whence itis forced in a continuous steady blast by the action of the spring K, while the pulley Dserves as a balance-wheel and insures steadiness in the action of the lower bellows.
What I claim as my invention is- A work-bench, A, provided with a crankshaft, B, operated by a treadle, C, in combination with the bellows Gr, crank-arm E, frame F, pulley a, belt I, springs J K, and pulley D, substantially as set forth.
