X-RAY TRANSFORMER HOUSING Filed Feb. 27, 1939 In I/en tor: Caper-fan BHors/ey.
Patented Jan. 27, 1942 UNITED, STATES PATENT OFFICE X-RAY' TRANSFORMER HOUSING Cap'erton B. Horsley, Toronto, Ontarim Canada, assignor, by mesne assignments to Sutton- Horsley Company Limited, Toronto,-ntario, Canada, a corporation of Ontario Application February 27, 1939, Serial No. 258,694
The principal objects of this invention are to provide an improved form of sealed housing for enclosing and firmly supporting the transformer, tube and other associated parts in an insulating body of oil and to achieve the maximum strength with the minimum weight and size.
A further object is to provide a casing for this purpose which will be effectively sealed against oil leakage but capable of being readily opened and re-sealed and which may be manufactured at low cost without expensive die equipment.
The principal features of the invention reside in the novel construction of the transformer housing from light metal sections which may be economically spun to shape and in the provision of clamping ring members which co-operate to seal the meeting edges together and toeffectively reinforce the same.
A further and important feature resides in the novel manner of incorporating a mounting member for the heavy transformer unit by forming or spinning the light metal of the housing thereabout in embracing and sealing relation to thereby effectively distribute the weight and strain of the transformer equipment about the light metal Figure is a fragmentary sectional elevation taken through the closure sealing means of one of the casing sections.
Figure 6 is a fragmentary sectional elevation illustrating a modification of the clamping means.
In the manufacture of portable X-ray equipment it is essential that the weight and bulk be maintained as low as possible, and since it is necessary to house the heavy transformer unit in some form of oil container, difiiculty has been experienced in providing an enclosing casing which would be sufliciently light and small and yet provide a firm support for the said unit and which at the same time would be of such construction as to guard against leakage of the oil and provide for ready access to the interior.
The present invention has been devised to overcome these difficulties and in the illustrated form thereof the transformer casing comprises an upper section I and lower section 2 each being preferably formed of thin gauge aluminum or other metal and, shaped by spinning so that the side walls present the required contour, here shown of stepped formation. The section I is formed with a peripherally enlarged upper zone 3 which tapers in to a reduced waist portion 4 which merges with a downwardly extending skirt portion 5. A clamping ring Bencircles the skirt 5 and the edge portion of the skirt is spun outwardly, to provide a clamping flange l.
The lower section 2 is here shown of smaller size than the skirt portion 5 but with a side wall '8 which flares outwardly to terminate in an outward flange 9. A transformer mounting ring I0 is placed on the flange 9 and the casing wall is spun thereabout to tightly embrace the ring III at the edge and outer side as indicated at H and I2 and the terminal edge is shaped into a cylindrical extension l3 which fits snugly within the skirt 5 of the section I, a sealing gasket It being placed between the flange portions I2 and I of the respective sections in encircling relation to the extension l3.
A clamping ring member I5 is flanged to embrace the out-turned flange 9 and clamping screws l6 extend through the clamping ring 6 and are threaded into the ring l5 to firmly draw the respective rings together into firm limiting contact while effecting the compression of the sealing gasket.
The casing sections are thus not only firmly clamped together in an effectively sealed manner but the clamping pressure set up will serve to firmly clamp the inserted mounting ring between the flanges 9 and 12.
In the modified form of clamping means shown in Figure 6 the ring member I5 is externally threaded while the ring 6 is internally threaded to effect the clamping by relative rotation of the rings.
Lugs l0 project inwardly from the ring I0 and are so positioned that the heavy transformer unit I! rests thereon and is secured thereto by the bolts I8 with the transformer windings illustrated in dotted lines l9, nicely clearing the walls 5 and 8.
An expansion bellows 20 is accommodated in the section 2 and one or more filament transformers 2| are mounted on the main trans- 22 are accommodated in the peripherally enlarged upper section I.
A central opening 28 is shown in the end of the casing section I ,and a clamping ring 24 encircles the same and the thin casing metal about the opening is spun back over the reduced flange portion 24'. A cupped closure member 2| is then placed in position with its flange 25' overlying a sealing gasket 20 and clamping pressure is then applied by means of a clamping ring 21 and screws 28, the cupped closure 25 being of a suitable material which will not deleteriously impede passage 01 the X-rays irom the tube 22.
The clamping ring 24 may advantageously serve as a mounting means for the shield or cone member 1! which may be detachably clamped by threaded means 30 entering a notch or recess ll in the ring 24. a It will be readily appreciated that with a construction such as defined a flrm and adquate support will be provided (or the transformer equipment even though the casing itself is of very light construction and the contour of the respective sections may be readily obtained by a simple spinning operation to closely conform to the units to be housed therein so that the size and weight will be reduced to the minimum and also the oil requirements, resulting in a strong and compact assembly.
What I claim as my invention is:
1. In a transformer housing, a casing formed of separable sections, one of said sections being flanged outwardly and having a transformer mounting ring overlapping the flange, the edge portion of said section being flanged to embrace the edge and opposite iace oi the ring and the other casing section having an out-turned flange, a sealing gasket interposed between the flanged portions of the respective casing sections, an annular clamping member engaging the firstmentioned flanged portion of the first section, and clamping means engaging the flange oi the second-mentioned section and co-operating with the annular clamping member to compress said sealing gasket and constrict the flanged portions of the first-mentioned casing about the clamping ring.
2. Apparatus as claimed in claim 1 in which the first-mentioned casing section is provided with a cylindrical extension adapted to present a sealing contact with the inner periphery of the sealing gasket and to extend into the other casing section.
3. Means as claimed in claim 1 in which said clamping means includes a clamping ring and said annular clamping member is of angular cross section to present a peripheral wall portion adapted to embrace the sealing gasket on the outer periphery and to engage the clamping ring in limiting contact.
