VARIABLE HIGH RESISTANCE.
Application filed April 2, 1923. Serial No. $29,294,
To all whom it may concern:
Be it known that I, GOULD GREEN, a citizen of the United States, and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Variable High Resistances, of which the following is a specification.
My invention relates to improvements in variable high resistances for use in electrical and wireless apparatus. The object of my invention is to provide an inexpensive high resistance element which ismechanically and electrically correct. 3
The accompanying drawing "illustrates one form of my invention, in which Fig. ,1 is a top view. Fig 2 is a cross-section along the line 22'.
Fig. 3 is a top view with plate a removed.
Fig. 4 is a top and side view of the slider.
Fig. 5 is a modification of my invention.
Similar letters refer, 'to similar parts throughout the several views.
Fig. 1 is a top view, showing the top plate, which is made of some insulating material such as fibre, etc., with the slot, 0, in which the part, 0?, of the slider, 6, moves. Also, a graduated scale, 9, is placed on this op piece, a. The eyelets, 72., hold the top plate, a, and the bottom plate, I), together and act as the terminals of the device. 7
In Fig. 2, the slider, e, is shown secured to the bottom, 6, by means of an eyelet j; and shows the manner of assembly. The high resistance element, Z0, may be a pencil mark on the bottom, 6, or any other high resistance material. This high resistance element is protected by the top, a.
Fig. 4, shows the slider, e, which has a depression, m, which makes contact with the high resistance element, k, as is shown in Fi (3.. The slider, e, istele'etrically connecte to. one eyelet'as shown at, p, in, Fig. 1.
Fig. 5, is a; simplified modification of my 'inventionin which the top plate, (2, 1s leftoff, and the graduated scale is placed on the bottom plate, .6, as-is shown. In this modification the high resistance, is, would be exposed to the moisture and dust of the atmosphere, which is undesirable The slider,
e, can be made of what is known in the trade as a tongue eyelet, which consists of the slider and the eyelet made in one piece. This tongue eyelet can be set into another eyelet so that it revolves freely. thus making an all metal bearing.
In operation, this resistance is placed in the electric circuit, using the two eyelets as terminals, and the slider may be moved as desired. The scale is not necessarily accurately calibrated to indicate resistance values, but is generally provided merely as a convenient means for recording various settings of the device.
claim as new:
1. In a variable resistance device, a plate of insulating material, a resistance element on said plate, a slider arranged to wipe over said resistance element, said slider having an integral eyelet portion by which it is pivotally secured to said base; a second plate of insulating material having an opening through which the free end portion of said slider extends, said second plate forming a protective cover. for said resistance element, said plates being secured together.
2. In a variable resistance device, a plate of insulating material, a resistance element secured to said plate, a slider having an integral eyelet portion by which it is pivotally secured to said plate, the free end of said slider being adapted to wipe over said resistance element; a second plate of insulating material superimposed on said first plate, said second plate forming a protective cover for said resistance element and having an arcuate slot through which the free end portion of said slider projects, means for securing said plates together and means for pivotally securing said slider to said first plate; both of said means being adapted to function as terminals for said device.
Signed at New York, in the count of New York and State of New York, this 31 day of March, A. D. 1923.
