UNITED STATES PATENT OFFICE INTERMITTENT GAUGE CONTROL FOR CON STAN TLY OPERATING MACHINES Harry Rimberg, Brooklyn, N. Y. Application June 23, 1938, Serial No. 215,350 6 Claims. (01. 192-127) This invention relates to gauge controls for consame reference characters throughout the several stantly operating machines and to gauge conviews.

One object of the invention is to provide an im- The advantages of the invention as here outproved device of the character described having lined are best realized when all of its features improved means whereby a gauge controls both and instrumentalities are combined in one and the starting and stopping of a normally constantthe same structure, but, useful devices may be ly operating machine, which gauge is intermitproduced embodying less than the whole.

Thus if the solenoid I1 is ener- 50 tion consists in the novel combinations and argized, both switches 25, 26 are closed simultanerangements of parts hereinafter described in ously. their preferred embodiments, pointed out in the Cooperating with the switches 25, 26 is an insubjoined claims, and illustrated in the annexed termittently operating switch means for controldrawing, wherein like parts are designated by the ling operation of the machine, this switch means M 2 29 introducing a retardation or lag so timed as to prevent interruption in the continued operation of the machine. For example, the switch means may include a pair of switches 30, 3| whose intermittent open positions occur at different times. As a whole, the switch means 29 operates in timed relation to the action of the indicator devices II, or to the completion of their action.
By way of illustration, I employ an actuator 32 rotating constantly at uniform speed and being of any desired size, and having an insulated cam element at 33 for successively opening the switches 30, 3|. Also carried by the actuator 32 is an eccentric pin 34 that works in the fork 35 of a lever 36 oscillatable about its pivot 31. Operated by the free end of the lever is a means, for instance, a head or finger 38 for periodically contacting and moving the sheet of paper |6 away from the indicator switches Each switch 30, 3| is normally closed, having a spring contact arm 39 for its fixed companion contact 40. With the actuator rotating in the direction of the arrow 4|, it is seen that the switch 35 is located in advance of the switch 3|, the cam 33 successively engaging the spring contacts 39 of these switches to open the same.
Desirably the switch 25 is connected in series with the switch 3| as by a conductor 42 and a conductor 43 connected to the return line 2| of the circuit. It is noted that the contact 28 is connected to the conductor l9.
From the switch 30 extend a plurality of conductors 44, 45, which lead to the power circuit of the machine 45a, and which may carry a higher voltage than the circuits hereinbefore described. These conductors 44 may be connected to the switch 26 as at 46, 41 so that the switches 26 and 30 are in parallel. A switch 48 for cutting out the machine control may be connected across the switch 26.
It will be understood that the switches may be gravitationally as well as spring operated and may also consist of mercury switches and the like.
The speed at which the device I0 is intended to operate may be indicated from the fact that the switches operate once every to of a second, and the solenoid operates every /6 to of a second, which indicates the reason for using a solenoid instead of a relay. The switches 25, 26, 30 and 3| operate at correspondingly high speeds.
In operation, the machine is started by placing a sheet of paper IE to close the indicator switches causing the solenoid to be energized. The latter closes the switches 25, 26, of which the switch 25 keeps the solenoid |'I energized, subject to the timed intermittent operation of the switch 3|, even if the switches become open. The circuit 44, 45 to the machine is closed by either of the switches 28 and 30, so that the machine shall not be stopped, these switches being arranged to open at different periods of time. Because the switch 3| is closed while the switch 30 is open, assurance is had that the relay is not deenergized and the switch 26 opened while the switch 30 is open. Should it happen that a sheet of paper does not close the two switches H, the solenoid I1 remains deenergized and the switch 23 remains open; then when the switch 30 opens, the machine stops. According to one point of view, it may be said that the time interval between the switches 3|], 3| allows for the lag of the solenoid IT, to assure opening of the relay at the proper time.
Obviously, the indicator means I I may indicate any desired condition, and may, for instance, be a gravity indicator upon which the element l6 may rest or from which it may be suspended,
It is thus seen that the invention comprises an indicator l, a first intermittent machine control 30, a second intermittent retarded means H, 25, 26, and 3| operated by indicator H for controlling the machine, the latter being operative by either means, and the second means being released subsequent to operation of the first means. The switch 3| may or may not be considered a part of the means that includes the parts I1, 25 and 26. If the switch 3| be considered an independent member for intermittently releasing the means I1, 25, 26, then the latter may or may not operate at regularly recurrent time intervals.
