Application an January 31, 1921. SerialIIo. 441,160.
The present invention comprises an improved X-ray apparatus which is particularly adapted for use infra diography. I
. It is theobject of my invention to provide an X-ray apparatus which is safe electrically and which at the same time may be i' eadily moved to a desired position and maintained firmly in that position 'when takinga picas awhole including the 'transformencas ing, and the oil filling, necessarily is heavier than the ordinary X-raytube. VJ hen supporting such a relatively heavy oil-immersed apparatus with relationto the part to be 7 radiographed or otherwise examined or treated, the supporting. arm niusteither be 'made heavy and bulky, 'or else it tends to vibrate or oscillate, thereby tending to pro-- duce indistinct radiographs. I'have found that one difliculty is caused by the tendency of the apparatus to rebound somewhatwhen moved to a desired position due perhaps to springiness and lost motion in the sup porting members. I have discovered that. a relatively light support maybe satisfac torily used for an X-ray outfit by providing a compressible member or. bufferfattached to the movable X-ray apparatuswhich'may be positioned in contact with a part'to be. I subjected to ,X-rays, andwhich will tend to followup any rebound of the device as a whole, thereby maintaining contact with the part to be subjected to X-rays. The novel features of my invention will be pointed out with greater particularity in the appended claims.
V In the accompanying drawing, Fig. 1
shows in perspective an embodiment of my invention; Fig. 2 is a longitudinal section of a part of my, improved 'device; Fig. 3 is a detail view partly in section of a suitable pivotal support; and Fig. 4 is a detail sectional view of a part of the supporting bracket.
The apparatus illustrated by Fig. 1 com shown) "the X-ray tube'being connected to j the transformer. terminals. An insulating liquid within the receptacle, preferablya' mineral oil, surrounds the 'X-ray tube,trans- ;Iormer,and connectlng parts As shown in the drawing, the only exposed part. of the low tension supply circuit are shortsections of'one of the conductors 17 which for the greater part of its length is contained with in hollow members of the supporting bracket. TheX-m tube'-may be conveniently mounted upon the supports attached to the cover 2 of the receptacle '1- The cover. contains awindow 3 which is permeable X- rays. An X-ray apparatusof this general type is described in Waite Patent .NO'.
1,334,936 issued March 23,; 1920; as shows inthis"patent, thehigh tension connections between the transformer secondary and the X-ray' tube terminals are concealed by being buried in: the oil within the containing tank. The receptacle 1 with its contained parts is connected by a holderftto a movable bracket 5, which may be of any suitableconstruction I adapted to render theoutfitfreelymovable to a desired position, that is, the several 7 joints 18in the support alford limited univ-e'rsal movement. The particularbracket illustratedcomprises a pluralityof'hinged members which enable the receptacle 1 to.
be moved outwardly in a substantially hori- .zontal plane as well as up and down in substantially a. vertical plane. The parallel arms 5, 6, are hinged inovably to. the holder l and are inturn movablyconnected to' a member 7. The'other parts ofthe bracket,
namely,the paired rods 8 9, andlO, 11 and the connector 12 are constructed to enable the X-ray device to'be freely moved in any desired direction. Theweight of the receptacle 1 and contained parts is equipoise-d by a spring 13, (see Fig. 4) contained within a hollow rod114, and connected to a cable 15, winding over an eccentric drum 16, shaped so as to counterbalance the X-ray apparatus comprising the receptacle 1 andits contents in all positions. 7 By this means stability is obtained in any position with r the limits of movement of the apparatus without clamping devices.
Projecting from the receptacle 1 oppo ite U a V 7 1,600,867.
the Window 3 of the X-ray tube is a tube 19 in line with the beam or" X-rays' emerge ing from the X-ray tube. As shown in Fig. '2 a 'secondtubeQO telescopeswithin the tube 19 hearing against a spring 21. V
V WVhen the describedapparatus is moved' against an object or patient to be radiographed the spring 21 is compressed slightly when the apparatus is positioned so that when the receptacle 1 tends to move away from the desired position, the follow-up 21 caus'e'st-he tube'QO to remain, in contact with the part which 1s intended to receive movement of the. slightly compressed spring X-rays.
:Thehatufe of the "yielding extension from the X-ray' outfit permits motion in only one directionthat is parallel with, the of bracket is provide the tubes 19, 20; inoth er directions the outfit; is rigid.
Preferably, the pet 22 of the supporting ii at itsb'aseivitha light coiled spring23, one end of the spring being connected to-the post 22 and the other end to. the pivot 24, so that aro'tati'on' ot the againstthe patient or objectto be radiographecl. Byth'eaction o'i the spring 23', torsionis exerted whierebythe X-fra'y apparatus is steadied and; held against the part to be? radiographed" thereby coacting with the spri'ngfll to .ste'adyfthe apparatus thus enabling-a clear picture to belt-alien. The
outfit is freely movable and adjustable. for
the operator, to di -ti erent positions. The: advan't'ageso-f this lightness, safety, freedom of motionlandstability in any locati onparticularly for such worl zlas dentistry will;
readily be appreciated. V g lVhat I claim as new and desire to secure byv Letters Patent States; is l )1. An X-ray apparatus comprisingan X-ray bulb, a housing therefor, a siipport of g the 1 United permitting a limited universal motion for said housing, an equipoise counterbalancin'g said housing with its, contents, and a'steadye ing device connected to said housing and adapted to be placed incontact with a sub- ]ect to receive X-ra'ys said device being compressible by a' slight t'orce exertedby l X-rayed. p V Q An Xaay apparatus comprising an X-ray tube, a' container therefor, movable supportlor said container, and a'tnbular extension fixedly connected to sa*id"'conminer and being constructed to be com'pres said suoport toward the subject to be I sible in an axial direction. p
