4x-Mar TUBE.
To all whom t may concern."
Be it known'that I, PHILIP A. FARRELLY,
a citizen of the United States, and a resident of Chicago, in Cook county, State of Illinois, have invented-certain new and use ful Improvements in X-Ray Tubes, of whlch the following is a specification.
This invention relates particularly to improvements in the method of mounting the stem which supports the anode.
In the drawings- Figure 1 is a side view of a tubeA embodying my invention. Fig. 2 is a sectional view on enlarged scale.
Referring to the-drawings, L denotes the tube, b the cathode, c the anode, d the anode stem, e the anode neck of the tube within which the stem is located and secured. Heretofore it has been the practice to punch holes through the anode stem near its outer end (the anode stem being made of a sheet metal rolled up to shape), these holes the glass of the anode neck of the tube. This left a that 1n shipping and handling the tubes it often happened that a sudden jar would and to press into sharp metallic edge` bearing against the glass, with the result' Patented Aug'. I5, raie.
Application led October 28, 1915. eria1LbTci.-58,72.
shift the anode stem in the neck, causing it to shear off the small glass projections.
This improvement consists in forming apertures in -the anode stem and drawing down the metal to form inturned tubular walls 5, connected with'the stem by curved surface 6, and pressing the glass into these tubular extensions. This provides a bearing surface of substantial area between the glass projections and the stem, and to a very great extent obviates any danger of breakage of the .glass when the stems have a tendency to shi t longitudinally due to a sudden 4jar or shock.
I claim as my invention In an X-ray tube, an anode stem apertured near its outer end and provided at 'the apertures with vinturned tubular walls, and projections from the neck of the tube extending into said apertures and bearing against said tubular 4walls to secure said stem in place.
