UNITED STATES PA NT GFFCE- GEORGE E. EAsTMAN, oEMINNEAroLIs, MINNESOTA.
IMPROVEMENT'IN GRIST-ALARMS.
Specification forming part of Letters Patent No. 154,948, dated September l5, 1874; application filed July 24, 1874.
To all 'whom it may concern:
Be it known that I, GEORGE H. EASTMAN, a resident of the city of Minneapolis, county of Hennepin and State of `Minnesota, have invented certain new and useful Improvements in Millstone-Alarms, of whichthe following is a full, clear, and exact description:
Figure 1 is a longitudinal center section view of my device, showing the conduit-pipe A empty. Fig. 2 is the same, showing the position of the pallet B when the pipe A is filled with running grain.
The same letters of reference are used in both figures in the designation of identical parts.
The object of my invention is to secure a simple, cheap, and perfectly effective device thatshall give to the miller or his assistant due notice that the material running through a conduit-pipe `to be ground has or is about to run out, said notice allowing of ample time to take such steps as may be necessary to prevent the` grinding-surfaces of the millstones from coming in contact.` The alarm may be used for such other purposes as it may be adapted for.
The conduit-pipe A leads from a grain-bin to a hopper. Within the pipe A is placed the pallet B, said pallet being hinged or pivoted at the point C. At-right angles to and attached to the pallet at the point of pivoting is a detent-pawl, H, projecting into the alarmbox sufficiently far to catch on the teeth of the wheel E. On the opposite side of the wheel E is an escapement-pallet, pivoted to the case at its center, and a prolongation, I, of the pallet has a hammer, K, upon it, to strike the bell l?. The wheel-E has a cogged hub on its inner face, which engages in the teeth of a wheel, E, upon which lies a coiled spring, one end being fastened to the spindle of the wheel, and the other end toits face at af. The spring is wound by means of a key fitting its spindle.
The exit of the grain from the conduit-pipe A allows the pallet B within said pipe to drop, as seen in Fig. l, which withdraws the projecting spur H from out the cog-wheel E, allowing its escape from the detent and the spring to revolve the wheel E', which, in turn, revolves the wheel E and gives the hammer K an intermittent motion through the escapement, striking the alarm.
The pallet B may be of any desired shape or form that may be required by the conduitpipe to produce the action necessary to operate the alarm.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
The grain-conduit A and the swinging pallet B, in combination with the detent-pawl H, clock mechanism E E', hammer K, and alarm P, all constructed, arranged, and operated substantially as set forth.
GEORGE H. EASTMAN.
