PATENT OFFICE.
ATTACHMENT FOR KEEPING SCREENS IN GOLD-QUARTZ MILLS CLEAN.
SPECIFICATION forming part of Letters Patent No. 782,861, dated February 21, 1905.
Application filed February 11,1904. Serial No. 193,109.
To all whom it may concern.-
Be it known that I, CHARLES G. LIDMAN, a citizen of the United States, residing in the city of Lead, Lawrence county, South Dakota, have invented a new Improvement or Attachment for Keeping Screens in Gold-Quartz Mills Clean, of which the following is a specifi cation.
1 attain this object by the mechanism illustrated in the accompanying drawings, in Which- Figure 1' is a vertical section, and Fig. 2 is a front view, of the attachment.
Similar letters refer to similar parts throughout both views.
A is the cam attached to the cam-shaft.
B is a piece of iron or steel bolted to the cam-floor and hinged in the middle, so that the end toward the cam will work up and down.
C is a connecting-rod, connecting the movable end of B to an arm attached to the shaft D, and this shaft is held by two brackets fastened to the lower side of the cam-floor, and
to this shaft is fastened the spring E.
F is a connecting-rod that connects another arm on the shaft D with the crank end of the screen-cleaner proper. In the center of this connecting-rod is a hollow piece with a threefourth-inch reducer in each end with thread cut therein to screw onto each end of the connecting-rod, so that the stroke of the screencleaner may be easily and accurately adjusted.
G is the screen-cleaner.
When the cam in its revolutions strikes the movable part or end of the hinged piece B, it presses it downward, which raises the screencleaner Cr, and when the cam releases B by force of the spring E the movable end of B is raised, which, by means of the arms and connecting-rod F, causes the screen-cleaner to strike against the screen H, and by reason of the stroke the screen is jarred and shaken, thus releasing all choking substances.
WhatI claim as my invention, and desire to secure by Letters Patent, is'
The combination with a mortar-screen. of a bail having side arms hinged to the mortarframe and connected to a moving part of the stamp to effect impact between the cross-bar of the bail and the screen, which by means of the combination set forth, operates substantially as set forth.
CHARLES G. LIDMAN.
