E. R. GOLDFl-ELD RADIOGRAPHIC UNIT Filed Sept. 24, 1928 INVENTOR w, @@JQ'KM Patented Sept. 16, 1930 UNETED STATES PATENT OFFICE EDWIN R. GOLDFIELD, OF CLEVELAND, OHIO, ASSIGNOR TO THE ENGELN ELECTRIC COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO RADIOGRAPICIUNIT Application filed September 24, 1923. Serial No. 308,078.
rl`his invenion relates to radiographic X- ray apparatus and the invention has for its object the provision of a simple compact and self-contained radiographic unit that will require little floor space and at the same time be operable with a minimum of effort on the part of the operator.
For this purpose I have found it necessary to include the high tension transformer and the entire high tension system as a part of the apparatus capable of adjustment upon the base thereof; and a further object of the ino will be apparent from the following description taken in connection with the accompanying drawings, in which Fig. l is an elevation in perspective of a radiographic unit embodying my invention; Fig. 2 is a detail in vertical section of parts appearing in the upper portion of Fig. 1; and F ig. 3 is a horizontal section as in the horizontal plane of line 3 3, Fig. 1.
Y The principal parts of the apparatus shown are a base 1 adapted to rest upon the floor and having a column 2 vertically extending therefrom; a sleeve 3 arranged coaxially of the column 2 for adjustment about the axis thereof an X-ray tube supporting carriage 4 vertically adjustable on the sleeve 8 but secured from axial movement relative thereto; transformer means 5 mounted on the sleeve 3 at the lower extremity thereof and having operative connections for the X-ray tube 6 which is supported by the carriage 1l, these connections comprising a high tension aerial system and including conductors 7 and flexible leads 8; and control means 9 for the transformer means and shown as mounted thereon.
The base 1 is a casting which may be provided with casters as indicated, and the column 2 thereof is conveniently tubular as indicated, Figs. 2 and 3.
The sleeve 3 is likewise tubular, fitting in telescoping relation about the column 2 and extending from the upper extremity thereof downwards through a majority of its length. rEhe sleeve is secured at its upper extremity with a cap 10 having a face portion 11 resting upon the linished top surface of the column 2, whereby the sleeve 3 is supported in `he position shown but is free to rotate upon the column Q about the axis thereof.
rlhe carriage 4 is bored out to fit and slide upon the sleeve 3 but is secured against rotation thereon as by a. key 12 which fits in a spline 13 extending along the outer surface of the sleeve. rlhe carriage has an arm 14C to which is secured the usual bracket 15 for the `-ray tube mounting which includes slideways 16 whereby the tube 6 may be adjusted radially of the column 2. A sheave 17 is carried by the cap 10, and a chain 18 secured to the carriage 4 passes over the sheave 17 and makes connection with a counter-weight movable up and down in the hollow of the column 2, whereby the carriage -lwith thc parts supported thereby is balanced in any position to which it may be moved. clamp 19 serves to secure the carriage against such movement if desired.
To the lower extremity of the sleeve 3 is secured a bracket 20 extending in the opposite direction from the arm 111 and carrying the transformer housing 21, which housing contains the transformer means for operating the tube.
Above the transformer housing 21 is mounted the control unit 9 which is thus associated with the sleeve 3 for movement therewith. yl"he proportion and relation of the parts is of course, such that the control handles 22 are at the proper elevation for convenient grasp by the opreator.
The conductors 7 lead upwards from the transformer housing 21, having support as by bracket 23 secured with the sleeve 8, and are bent to extend generally over the tube G. The extremities of the conductor are provided with reels 24; carrying the leads 8 which afford proper connection with the X-ray tube through its range of adjustment.
It will be observed that by the arrangement described the X-ray tube 6 may be adjusted vertically by sliding'the carriage ll; and may be adjusted horizontally by swinging motion about the axis of the columnV 2, but such swinging motion will be accompanied by corresponding motion of the transformer and rcontrol means, as well vas the high tension aerial system which connects the tube with its transformer means, these parts moving as a unit. Thus the operator when he has swung the tube over the desired parts to be radiographed will always find the control handles 22'in the same relative location so that they may be manipulatedwith the least liability of error. Likewise, the transformer means always serve to balance the tube mounting, and, being of relatively great weight, are low enough so that ythecenter of gravity of the entire apparatus is not dangerously high.
What I claim is:
X-ray apparatus comprising a base adapt- Y ed to rest upon a floor and having a vertically extending column, a sleeve mounted coaXially of saidcolumn for adjustment about the axis thereof, anX-ray tube supporting carriage vertically yadjustable on said sleeve but secured from axial movement relative thereto, transformer means mounted on ysaid sleeve and having operating connections for an X- ray tube 'on said carriage, and control means for said transformer means, associated with said sleeve for movement therewith, and adapted to be manipulated bv an operator standing on said floor, wherebysaid Vcontrol means with said tube may be adjusted about said axis asl a unit their angular relation however, being fixed.
In testimony whereof I hereby ax my signature.
EDWIN R. GOLDFIELD.
