JOSEPH A. JOHUM, OF NEW YORK, N. Y.
SHUTTLE-MOVEMENT FOIR SEWING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 282,729, dated August *7, 1883.
' Application filed January 29, 1883. (No model.)
To all whom-it may concern Be it known that I, JosEPH A. J OHUM, of
the city, county, and State of New York, have invented certain new and useful Improvements in Shuttle-Motions fo'r Sewing-Machines, of which the following is a specification.
This invention relates to an improved shuttlemotion for sewingmachines; and the invention consists of the combination, with the lower driving-shaft, of an oscillating extensible arm, pivoted to the under side of the sewing-machine table, provided with a shuttlecarrier at one end and with an adjustable extension-shank at the other end, said shank having a ball designed to form a part of a balland-socket joint, an adjustable eccentric on said driving-shaft, and an arm connecting the extensible shank of the oscillating arm with said eccentric. By this construction the throw of the shuttle may be regulated as desired, the extension-shank and eccentric being readily adjustable to correspond with each other.
In the accompanying drawings, Figure 1 rep resents avertical longitudinal section of a sewing-machine with my improved shuttle-motion. Fig. 2 is a bottom view of the same; Fig. 3, a vertical transverse section on line mm, Fig. 1; and Figs. 4., 5, and 6 are details of the working parts of the same.
Similar letters of reference indicate corresponding parts.
A in the drawings represents the table of a Singer or other sewing-machine for heavy work; B, the lower driving-shaft, which receives its motion by the usual transmitting mechanism from the upperdriVing-shaft of the machine. An eccentric, O, that is secured by a collar, 0, and set-screw O to the shaft B, imparts motion to an arm, D, that is strapped around the eccentric O, and retained thereon by disk-shaped side plates, D.
The outer end rear end, E, of an arm, E, that is fulcrumed I to the under side of the table A, and provided at its opposite end with a shuttle-carrier, E The eccentric O is adjustable on the shaft, to correspond with the adjustment of the stem or shank c, and by these means the throw of the shuttle is regulated and an easy movement of the machine secured. Oscillating motion is imparted to the arm E of the shuttle-carrier by its ball-andsocket connection with the arm D of the eccentric O, the adjustable ball-shank e admitting theeXact setting of the oscillating arm E in the socket of the oscillating arm D, as required for the easy and effective running of the sewing-machine.
The parts form together a shuttle-motion of great simplicity, which is readily adjusted and little liable to wear, so as to be specially adapted for sewing machines doing heavy work.
Having thus described my invention, I claim as new and desire to secure by Letters Patent The combination, substantially as set forth,
of a driving-shaft, an oscillating extensible
