Description
Feb. 18, 1930. s. sci-NACHO HIGH TENSION SWITCH FOR X-RAY APPARAT-US Filed 00'6- 29. 1927 Patented Feb. 1S, 1930 UNIT STATES STEFAN SCHVACHO, OF TRENCANSKE TEPLICE LAZNE, CZECHOSLOVAKIA HIGH-TENSION SWITCE- FOR X-RAY APPARATUS Application led October 29, 1927.
The object of the invention is to provide a high-tension switch for X-ray radiators whereby it is possible to switch different elec tric currents, with one apparatus to supply different lamps, as for example X-ray lamps, quartz lamps, solus lamps, Finsen lamps and the electromagnetic lamps.
This switch is fastened on its proper porcelain insulators and has a separate chamber on the manipulating` table whereon the whole switch is mounted. Back of this chamber is another smaller compartment, in which sheaves are located. Due to these sheaves the switch rotates. On the front face of the distributing board a switch-handle is located and through this handle the switch is movable.
In the accompanying drawing` Fig. 1 represents a front view of the apparatus looking towards the switch-handle. F ig. 2 is a crosssection of the switch. Fig. 3 is a longitudinal section of the switch.
On the X-ray radiator manipulating table (1), the manipulating switching and distributing chamber (2), is located. This is constructed with two compartments (7) and (8), and with the distributing board (9). These two compartments (7) and (8) are necessary because, on the distributing` board (9), the low-tensi-on wiring is located while in the compartment (8), the high-tension induction current circuit is placed. Therefore, between these two chambers (7) and (8) an insulating wall (10) has been placed to prevent the high-tension induced current from passing on to the front distributing board (9).
Tn the rear compartment (8) the high-tension switch is installed. This switch comprises four insulators, three of which, designated by numeral 3, are anchored fast to their support while the fourth, designated by numeral 4 is movable. To the top insulator (3) a Contact fork (11) is Jfastened, which is directly connected to the outgoing conductors (not shown). Into this contact fork (11), a knifeswitch (6) is inserted. The knifeq Serial No. 229,695.
switch is movable from left to right. To the lower insulator (4) also a contact fork (13) is fastened. In this fork is a sl-ot (14), through which a screw (15) passes and is fastened to the knife (6) to make the knife move to the right or left as required. To the side insulators (3), contact springs (5) are fastened and these are connected to their respective circuits.
The lowest insulator (4) is firmly fastened to the moving shaft (12), which turns in the bracket bearing-arm (16) and carries the turning sprocket (17) which is located in the compartment (7). A steel ycable (18) is fastened to the sleeve (17) and passes over the guide-sprockets (19). On the front face of the distributing board (9) is al lever-arm (20) and contact clamps (21). To the lever-arm (20) a sprocket-wheel is fastened and engages with the cable 18, so that when the lever-arm is moved, it sets into motion the steel cable (18) the guiding sheaves (19) and sprocket (17).
lVhen using and connecting the switch the following operations are required Lever-arm (20) is brought in Contact with the upper contact clamps (21) on the front distributing board By moving the lever-arm (20), there is set in motion the sprocket-wheel (22) through which the steel cable (1S) the guidesheaves (19) and the turning sprocket (17), to which steel cable (18) is fastened with a screw not shown, also are set into motion. Sprocket (17) is keyed, firmly fastened to the shaft (12) to which the insulator (4) is made fast. Then by moving the lever-arm (20) the insulator (4) will move into the required angle and will connect the knife-switch (6), to the connection on spring (5) and thus the circuit will be closed as may be seen in Fig. 2.
When it is desired to have the switch disconnected then the lever-arm (20) must be brought into a. horizontal position and the knife-switch (6) will be in the center as seen in Fig. 3, Thus nothing will be connected.
I claim:
In an X-ray radiating apparatus of the character described, a chamber divided into tWo compartments, separated from each other by aninsulating Wall, and having a distributing board, forming an outer Wall to one conipartment, a plurality of insulators Within one compartment, one being movable, and the others anchored, knife switch blades mounted on said insulators and in circuit With high tension current conductors, and means for operating the movable switch blades7 located outside said compartment.
