STEFAN SCHVACHO, O TRENCIANSKE TEPLICE, LAZNE, CZECH()SLOVAKIAV COMBINATION X-RAY RADATOR Application led October 29, 1927.

The obj ect of this invention is the embodiment into one single apparatus of an X-ray generator, a quartz sun lamp, Finsen lamp, and solus and electromagnetic lamps. At

5 the present time for each lamp a separate unit (apparatus) is vrequired because it is essential to use too absolutely dierent currents.

The X-ray generator requires high-tension current with constant interruption, while the quartz sun lamp and the others operate on the ordinary low tension house current. For above stated reasons each lamp requires a separate apparatus and equipment, which is costly and requires more room or iioor space, thus causing difficulties with constant relocation of the equipment and provides high maintenance.

To eliminate the above stated diiiiculties,

and to make it possible for every physician to own and use all five lamps the apparatus constituting the subject mattei' of this application has been devised.

This invention eliminates the necessity of live separate units and makes it possible to accomplish in the most perfect way in each case with one apparatus the work of live, due to the switching layout of the two separate well known electric systems of the X-ray generator and the quartz sun lamp, etc., in a combination which makes it possible with one and the same apparatus to operate the X-ray generator, the quartz sun lamp, etc. This is made possible by the layout and arrangement of the switching systems in a close space, in other words'in a chamber of small dimensions.

In the accompanying drawing:

Figure 1 is a diagrammatic view represent 40 ing the apparatus embodying my invention arranged and adapted for use as an X-ray generator; Figure 2 is a similar view with the apparatus arranged and adapted for use in construction with a quartz lamp, Finsen lamp, or electromagnetic lamp.

The fundamental progress which shows the combination of these two circuits is due to the fact that the service distributing board is made in two parts, one switching part and amanipulating distributing board. Through Serial No. 229,692.

the arrangement of this switching distributing board it is possible to use or operate on this single apparatus the X-ray generator, the quartz sun lamp, the solus lamp, the Finsen and the electromagnetic lamp, wherefore 5r the work in operating only one apparatus is shortened and the expenses are reduced.

Fig. (1) Then used for X-ray generator, on the distributing switching board (not shown in drawing) a two-pole switch (a), is 69 located, which is hooked (connected) tothe lower contact clips (11). The current flows as follows From the circuit through the fuse (5) into the two-pole switch (t) the negative current flows through the clamps (11), 65 into the ammeter and into the inductor (2), the secondary coil (21), Ithrough here it proceeds into the interruptor he positive current iiows through the clamp (11), from here into the rheostat (6), and 7o intoA the interrupting switch Across these two connections a voltmeter is inserted (7).

The prime circuit- (20) of the inductor (2), is connected tothespark-gap One conductor to clamp (11), and the other conductor through the milliameter (9), into the other clamp (11). This clamp (11), is separately connected to the single pole switches (10); these are located at proper distances so between themselves on the distributing switch-board (which is not shown) and directly connected to conductors (18), of the X-ray lamp (1), therefore as soon as the interrupter (12), switch (13), are connected, 85 the X-ray lamp 1) is lighted.

(2) When using the combination apparatus for the quartz lamp or the other lamps, we replace the X-ray lamp (1) with the quartz lamp (14), or any other' lamp and change the two-pole switch to the upper contacts (16), at the same time we change the single pole switches (10),'to the upper contacts (16). and the path of the current 95 will be as follows: From the house circuit the current will ow through the fuses (5), into the double pole switch vll), thence to the clamps (16). Here the positive current goes to the rheostat (15), from here to the clamp 100 (16), of the single pole switch (l0) and this is connected to the quartz lamp (14) The negative current flows from the clamp (16), of the two-pole switch (4) into the clamp (16) of the single-pole switch (10), and thence into the quartz lamp (14). From the rheostat (15), the current of the auxiliary pole flows through the conductor (17), into the quartz lamp (14) or any of the other lamps. As soon as the rheostat (15) handle is connected the quartz lamp or any of the f other lamps will be lighted. When not using the combination apparatus all switches must be disconnected.

I claim:

A convertible apparatus for the supply of current to an X-ray generator, a Finsen lamp, or quartz lamp, and an electromagnetic lamp, comprising a service distributing board, current supply connections, a two pole switch on saidboard in circuit with the current supply connections, switch contacts constituting the terminals of separate circuit leads, and arranged in pairs, a transformer, the primary coil of which is in said circuit through one pair of said switch contacts, and

f a current interrupter in circuit with said primary coil, and constituting a path through which said Circuit is completed; a second circuit leading from the second pair of switch contacts through and including the second- .ary coil of said inductor and having connections adaptable to an X-ray tube, and to the other forms of lamps, the two circuits having their leads and conductors mountedon said distributing board and constituting a unitary system, controllable through said switches arranged and adapted to switch into use alternately high and low tension currents.
