Description
' E. B. SISSON LOW LEVEL SIGNAL July 31 1928.
Filed Sept. 20, 1926 Patented July 31, 1928.
EDMUND B. SISSON, 0F PASGO, WASHINGTON.
LOW-LEVEL SIGNAL.
Application filed September 20, 1926. Serial No. 136,607. g
This invention relates to a signal device for use on linotype machines, the general object of the invention being to provide means for sounding an alarm when the metal in the pot reaches a low level so that the operator will be warned that the pot needs replenishing.
Another object of the invention is to so devise the device that it is held in place by some of the bolts in the machine and without removing any of the parts of the machine.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.
In describing my invention in detail, ref erence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a View, with parts broken away, showing the invention in use.
Figure 2 is a view of the invention itself.
As shown in these views, the device consists of a bracket 1 which is composed of a perforated base 2 and a V-shaped hori- Zontal part 3; the hell 4 attached to the free end of the V-shaped part 3 and the hammer lever 5 which is pivoted to the small end of the V-shaped part by the screw 41. The base 2 is fastened to the pump lever bracket A by some of the bolts which are already in the bracket, and the outer end of the hammer lever 5 extends under the pump arm B, so that when the metal in the pot 0 reaches a low level and the plunger D is operated in the lower part of the pot, the arm B will strike the extended part of the hammer lever 5 on its downward-stroke and thus tilt the lever on its pivot, so that its head will fall upon the bell on the up stroke of the arm B. Thus the alarm will be sounded on each double stroke of the pump so that the operator will know that the metal is low and that the pot must be refilled. A projection 6 on the part 3 of the bracket 1 limits the downward move-' ment of the head of the hammer.
As will be seen, the invention can be easily and quickly applied to a linotype machine without moving any of the'parts thereof and without boring holes'in any part. It will also be seen that the device will not interfere with any part of the machine, and that it is so simple that it can be manufactured to sell'at low cost and it is not likely to get out of order.
It is thought from the foregoing description that the advantages and novel features of myinvention will be readily apparent.
I desire it to'be understood that I. may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.
lVhat I claim is 1. In combination with the metal pot and pump of a linotype machine, an alarm mechanism actuated by the pump arm when the metal in the pot reaches a low level.
2. In combination with the metal pot and pump of a linotype machine, a bracket attached to a part of the machine, a bell attached to a part of the bracket and a hammer lever pivoted'to the bracket and positioned'to be tilted by the pump arm to strike the bell when the metal in the pot reaches a low level.
3. In combination with the metal pot'and pump of alinotype machine, a supporting bracket adapted to be attached to the pump lever bracket by some of the belts in the bracket, a bell carried by the supporting bracket, a hammer lever pivoted to the supporting bracket and engaging the bell when the lever is rocked by'the movement of the pump arm when the metal in the pot reaches a low level, and a stop on the supporting bracket for limiting the movement of the hammer lever.
4. In combination with a metal pot and pump having a'pump arm, a' bell arm piv-j otally supported intermediate its ends and having a tapper on one end thereof, the opposite end being adapted to be brought into the path of said pump arm when the metal in the pot has been lowered to a predetermined level.
