This invention relates to'variable cons rs as: n ediihZ wirel tsqandm her instruments and has for its object to provide an improved construction and arrangement of condenser which is particularly adapted to enable the tuning of several circuits to be effected from one control member in a simple manner.
My invention comprises a variable condenser in which the fixed and moving elements are arranged so that the capacity of the condenser is changed from minimum to maximum more than once in each half revolution of the moving elements.
My invention further comprises a variable condenser which consists of fixed and moving plates having peripheral gaps or slots and inwardly extending tongues, gaps and tongues coming into alignment more than once in each half turn of the moving plates.
My invention further comprises the cornbination with a. variable condenser as before referred to, of one or more condensers or variometei's connected to said variable condenser either direct or through gearing.
Referring to the accompanying sheets of explanatory drawings Figure l is a sectional view and Figure 2 an end view looking from right to left of Figure 1 of one of my improved condensers coupled to an ordinary condenser for tuning two circuits from one control member.
Figures 3 and t are detail views of one construction of the fixed and movable plates of my inn'iroved condenser.
The same reference letters in the different views indicate the same parts.
The two condensers illustrated in Figure l are arranged in the ordimiry known manner with alternating fixed and moving plates. and r.- indicnting fixed plates and b and ri moving plates. The lower condenser e is of usual construction but in the condenser f at the top side of Figure l, the.
th ouglr ithel fined-i plflffiiris e'sli htlm lla'rger iimlltlhhe cotrespondingnmetal; centre'njzioi the moving plates. The diameter k of the peripheral edges of the slots between the tongues g of the fixed element is sli htly greater than the overall diameter 0 the moving plates.
The condenser e is actuated by the spindle m and the latter is geared through the wheel )2, fast on the spindle, the wheel 0 on a spindle havin the wheel p thereon, and the pinion g to the sleeve 1* which carries the moving plates of the condenser The said gearing provides that the moving plates (1 of the condenser 7' turn through several complete revolutions during a half turn of the moving plates Z) of the condenser e.
By reason of the construction of the plates 0 and d, one turn of the plates 0 causes the capacity of the condenser f to be changed from minimum to maximum 12 times. If the gear ratio between the condensers be 1 to 12, then for one half turn of the condenser e, the condenser f will change in capacity from minimum to maximum 72 times. With this arrangement therefore it is possible to obtain an approximately accurate tuning of the two condensers by the operation of one control element which ma. be on the spindle m or on the sleeve '1'. A nob s and finger 1- moving over a dial it are shown on the sleeve r. I
The insulating arrangements of the condensers have not been described as they are usual in character. The gearing between the condensers may be made of vulcanite or like insulating composition.
Instead of being in the form of plates, the fixed and moving elements of the condenser may he in the form of co-axial tubes with longitudinal slots and tongues.
The number of slots and tongues in the moving and fixed plates may be varied to suit requirements.
What I claim is 1. In the combination of two variable condensers arranged in coaxial alignment, a shaft on which said condensers are mounted, the stationary and movable plates of one condenser being each provided with a plurality of similar tongues and slots whereby the capacity is varied from minimum to maximum a plurality of times for a rotation of 180, the other condenser being provided with fixed and movable plates providing a change from minimum to maximum for a rotation of -l80".,i a.nd means on said shaft. connecting both sets of movable plates for rotating one from the other.
2. In the. combination 0I two variablepoudensei's arranged in coaxial alignment, a shaft on which said condensers are mounted, the stationary and movable plates of one condensen-heing each provided with a plurality of similar tongues and slots whereby the capacity is varied from minimum to maximum a plurality of times for a rotation of 180 the other condenser being provided with fixed and movable plates Providing a change from minimum to maximum for a rotation of,l 80",, and moons on said shaft connecting both' sets of movable plates, to causea smnll motion of one set to be transmitted into a large rotation of the other set.
In testimony whereof Ihavesigned my name to this specification.
Rii LPH LEONARD ASPDEN.
