Dominican Republic 1 Application J anuary- 26, 1949, Serial No. 72,961

1 My invention relates to multiple X-ray picture seriating devices, and particularly to means whereby a series of exposures can be made in predetermined arrangement and location on a single sensitized film, plate or the like, of standard dimension as now ordinarily used.

The object of this invention is to provide a device that can be employed with radiographic apparatus as now used, and which will permit the production of four or six exposures or pic- 2 tures on the usual eight by ten inch or other standard sized film as now supplied commercially in cassette form for X-ray use.

Another object is to provide a multiple X-ray picture seriating device with which six exposures or pictures can be located or seriated upon a single elongated rectangular film with three exposures along each side following the longer dimension.

A further object is to provide multiple X-ray picture seriating device structure that can be readily employed with X-ray and radioscopic apparatus as now in use.

Still another purpose is to provide structure of this character including a pair of rotatable masking disks having exposure openings therethrough at different locations with respect to the center of rotation, together with means to rotate said disks to bring selected openings of the two disks into registry and to revolve the location of the registering openings and expose these openings at desired seriated locations whereby a plurality and series of exposures and pictures can be produced in desired serial location on a single sensitized film.

Another object is to provide two rotatable masking disks having picture or exposure openings therethrough at different locations with respect to the center of rotation, with the two disks being capable of rotatable movement to revolve those portions through which the exposure openings are provided and thus dispose the two disks in such relative position that the opening adjacent to the center and the opening further from the center can be cleared, with the other opening masked oii, together with means manually actuatable to move one or either or both of the disks to accomplish the desired registration of either set of openings, and the desired revolution of the disks to present the registering openings in adjusted and predetermined positions required for seriated projections of the series or multiplicity of pictures upon the sensitized film.

:cStill another purpose is to provide means im 6 Claims; (Cl. 250-66) 2 penetrableby X-rays to mask out all other pore tions so that the usual cassette can be subjected to six exposure intervals for taking the six de: sired separate exposures at the different locations, without danger or possibility of accidental, light penetration or exposure.

Still another purpose is to provide a multiple X-ray picture seriating device which can be used with X-ray equipment as already installed, and which will make it possible to give a complete showing and history on say three films, a single film or exposure being made in the usual manner to show the entire area, and then one or. two or more films each showing a seriated plurality of smaller related pictures, as for example of a suspected area or a single area in different conditions of functioning, or a member such as a finger in different positions, thus making it possible to greatly reduce the usual X-ray cost and expenses by showing on two or three or more films a multiplicity of different positions or phases that would ordinarily require an expensive series of separate pictures and a sep-' arate film for each picture.

Still another purpose of my invention is to permit location of exposures on a single film in such serial arrangement and placement that they can be readily viewed and the several exposures can be compared without recourse to and handling of a number of separate films.

With the above and other objects in view, some of which will be apparent to those skilled in the art, and others of which are inherent in the construction and use of the device, my invention includes such novel features of construction and assemblies of parts which will be hereinafterset forth in connection with the drawings.

In the drawings:

Figure l is a view in perspective showing an embodiment of my invention.

Fig. 2 is a view in elevation looking from the opposite side from the showing in Figure 1, and with the cover plate removed and parts in sec tion to better illustrate the construction and assembly of the device.

Fig. 3 is a vertical sectional view taken sub-- stantially at right angles to the device.

Fig. 4 is a view in elevation showing one of the exposure seriating and cassette shielding disks.-

Fig. 5 is a view similar to the showing in Fig. 4 disclosingthe second disk. 1

Fig. 6 is an enlarged perspective view to bet ter disclose the retaining means employed to hold the disk in adjusted position. v

Fig. '7 is an enlarged fragmentary perspective View to better illustrate the disk manipulating and revolving means.

The supporting structure is made up as a substantially rectangular case having surrounding edge walls 2, so that this supporting structure becomes in fact a containing case for the other portions of the device. The open side of the case structure as thus provided is adapted to be closed by a cover plate or wall 3, held in place by screws or other suitable fastenings. The cover plate 3 is extended on opposite edges beyond the edge walls 2, to thus provide projecting slide flanges 4 and 5. These projecting slide flanges 4 and 5 can be made to fit standard parts of an X-ray ma: chine or apparatus, to thus permit ready placement and removal of the case with respect to the X-ray equipment. i 1 I Since my invention is adaptable to be fitted and used with various types of fluoroscopic and radiographic apparatus, and those skilled in the art will readily understand and appreciate the manner of fitting my device in place for use, no attempt is here made to illustrate or particularly describe any type or construction of X-ray apparatus. Furthermore, the device of my present invention relates to seriating parts and features, rather than to the electrical parts or X-ray portions of the apparatus with which my device is used.

I. The housing structure, including sidewall l, edge walls 2, cover plate 3, and other portions of the supporting structure, can be made of aluminum or other suitable metal, of sheet or molded plastics of transparent or translucent properties, and in fact of any other suitable material that will give support to the parts and will allow penetration of X-rays.

f A bearing shaft 6 is carried substantially centrally within the casing or housing space as defined by the edge walls 2, and in the present instance I'have disclosed this bearing shaft as being carried by the-cover plate 3 and extending inwardly substantially toward the sidewall I. seriating and masking disks land 8 are made to be of generally circular outline, and are provided their "middle" portions with bearing openings 9 and i0. These bearing, openings 9 and H3 accommodate bearing shafts so'that the two disks are rotatably mounted within the casing structure to be revolved on the same general axis, either inr dependently or together.

These seriating and masking disks 1 and 8 are of sufiicient size to have an area greater than and to covera sensitized film or sheet of usual commercial size, aspfor example on 8 x 10. inch .X-ray film, and the disks 1 and 8 have a lead shielding or masking covering thereon as indicated at II and [2, respectively. I Thedisk I has a picture exposure opening l3 therethrough and through the lead shielding H, ifset from the central bearing opening 9 and yet inwardly from the peripheral edge of the disk, and'a similar opening I4 is provided through the disk 1 and its shielding II, at a location spaced outwardly from the central bearing openings. Disk 8, and its shielding I2, have an exposure opening [5 therethrough spaced from the center of 'rotation a distance to substantially register with the opening [3, and disk 8 and its shielding have a second opening l6 therethrough positioned to register with opening [4 when the disks are rotated to bring these openings I4- and [5 into alignment. The openings l3 and M of disk I, and the openings l5 and iii of disk 8 are so located that-when one set of openings is in alignment,

the other set is closed. By this arrangement, the disks 1 and 8 can be moved independently or 'relatively to close all openings, to bring openings l3 and i5 into aligned registration, or to bring the openings l4 and I6 into aligned registration and to close or block out all other openings.

As is set forth above, the device of my invention is intended and is adapted to permit ex-' posure of six independent pictures or areas of a single elongated sensitized sheet, such as the usual X-ray film as now supplied in commercial form in cassettes. In Fig. 8 of the drawings, I have illustrated diagrammatically such a film, at I and have indicated the seriated positioning and the area of six exposures or pictures within the'film area. As here shown, the four corner exposures or picture areas are indicated at a, b, c,

and d, and theseareas can be exposed through the exposure openings l4 and I6 of masking disks 1 and 8, when these openings are brought into registry and the disks 7 and B are then* rotated together. Heretofore four pictures have been taken on a single X-ray film of the usual elongated rectangular form, but this has meant that only four exposures could be made, and the remaining area of the sensitized sheet is worthless and is lost. By bringing the openings l3 and [5 of the disks 7 and 8 into registry, and then rotating the disks together to accomplish disposition of the registering openings substantially laterally with respect to the bearing openings 9 and I!) it is possible to open an exposure or picture area at the lefthandside, as at 6, between the areas a and d, and to open for exposure a similar area at the righthand side between the areas I; and c. In this manner, it is possible to provide for exposure and showing of six pictures on the usual X-ray film, and to substantially use the greater area of the film, without resulting wasteor unused large areas.

As has been explained, the film or other sensitized sheets, in cassette or other form, will be placed and will be held for exposure in the usual manner and with usual X-ray apparatus, and no attempt is here being made to particularly illustrate or to describe film holding means.

In Figure 1 of the drawings I have attempted to illustrate'by dotted lines something of the gen-1 eral location of areas of exposure that can be accomplished with-my improved structure;

It will of course be appreciated that the rela' tive areas of exposure for accomplishing the radiographic pictures will result from independent movement of either or both of the disks 1 and 8, and by simultaneous movement of these disks when the desired exposure openings are in registry, and to this end I provide means to rotate the disks independently or together, as may be desired, and means to retain desired settings of the disks.

With the above adjustment and manipulation of the disks in mind, disk 1 is provided with peripheral ratchet teeth It, and. disk 8 has peripheral ratchet teeth l9. These ratchet teeth are preferably of equal size or length on the two disks, and are faced in the same direction, on both disks. Thus, by providing movable means to engage in the teeth of the two disks, it is possible to move or rotate each disklseparately, and to revolve the two disks together.

The casing or housing structure has an elongated opening 29 through one side edge thereof, and disk revolving means, generally indicated at 2| is provided with an operating handle 22 ex-. tendingthroughthis elongated. opening -t0-be manually grasped and manipulated to accomplish desired revolution of the disks. A shield 23 is provided around the elongated opening 20.

The disk revolving means includes an elongated member 24 having a bearing 25 at one end pivotally fitted on bearing shaft 6, and having a straight handle receiving portion 26 at the other end by which handle structure 22 is carried. In the intermediate portion, this elongated member 24 is bowed or formed to follow a substantially semicircular arc, as at 21, to thus oifset the intermediate portion of the elongated member so that it will clear and will leave unobstructed the registering openings l4 and I5, when an exposure or picture is to be made through these registering openings to give exposure and picture at one side of the film or sensitized sheet. The bearing portion 25 is fitted on bearing shaft 6 intermediate disks I and 8, and the straight extending portion 26 thus projects substantially radially from between the disks I and 8 and through the elongated opening or slot 28. The operating handle 22 is a preferably substantially rectangular tubu lar construction which fits over the extending end of the handle or elongated operating portion 24 and serves as a housing for ratchet means engageable with and released from the ratchet teeth I8 and I9.

The straight handle carrying portion 26 has a pin 28 extending therethrough and projectin on each side; and, ratchet carrying bars 29 and 3B are disposed on opposite sides of the straight handle carrying portion 26 with the ends of the pin 28 slidably received in slots 30. In this way, the ratchet carrying bars 29 and 3a are slidably mounted on the straight portion 26 with their inner ends presented adjacent to the ratchet teeth 18 and I9 of the disks I and 8. Ratchet pawls or dogs 32 and 33 are swingably or rackably mounted at the inner ends of the ratchet carrying bars 29 and 3D, and springs 34 and 35 are provided to resiliently hold the pawls or dogs 32 and 33 in ratcheting relation.

The ratchet carrying bars 29 and 3B are provided with screwthreaded openings 36, and operating handle portion 22 has slots 37 there through registering with these openings 36. Thumb pieces 33 are provided on each side of the tubular operatin handle portion 22, and have screws 39 received in the openings 36 and slidable through the slots 31. With this arrangement, pulling or pushing force can be exerted on either or both thumb pieces 33, and in consequence the ratchet carrying bars 29 and 30, separately or together, can be moved into position so that the ratchet pawls or dogs 32 and 33 will engage with and will be disengaged from contact with the ratchet teeth l8 and I9. I i I Substantially U-shaped bracket members 48 and 4! are carried within the casing structure and embrace the ratchet teeth edges of the disks 1 and 8 to prevent displacement of these disks. As has been stated, it is desirable that means be provided to resiliently retain the disks I and 8 in such positions to which they may be adjusted. With this in mind, I provide a substantially E- shaped bracket member 42 within the casing or housing, this E-shaped bracket member being perhaps best shown in Fig. 6. The central branch 43 of this bracket 42 is disposed in the space between the disks I and 8, and the outside branches 44 and 45 are disposed adjacent to the outer sides of the disks. The arm portions 44 and 45 have bearing openings therethrough, and detent balls 46 and 41 are fitted loosely in these openings,

springs 48 and 49 being secured on the outer'sides of the arms 44 and 45 to exert yielding pressure upon the detent balls 46 and 41 to urge these detent members into contact with the outer sides of the disks I and 8. The disks I and 8 have a plurality of detent recesses 50 formed in the outer faces thereof at predetermined and desired loca-- tions, and aligned to receive the detent balls 46 and 4! to thus resiliently retain the disks land 8 in desired set positions. As stated, it is desirable that detent recesses5il be so located that the disks with the exposure openings in aligned re-' lation will be positioned to permit seriated exposures to accomplish a picture substantially in the composite and serial sequence and arrangement and placement as indicated in Fig. 8;

In the use of my multiple X-ray seriating dcvice, where the casing is made of transparent or translucent material, the operator can view the parts to accomplish desired registration ofexposure openings of the two disks, and to adjust the parts in the serial arrangement or desired set: tings for the seriated sequence. As the disks are revolved, the registering exposure openings will be revolved in their relative disposition and six exposures can be made to accomplish the showin of six pictures on a single elongated rectangular film of commercial size as now supplied in cassetteform for X-ray use. With the projecting slide flanges 4 and 5 serving to support my device in place, the device can be readily fitted into position for use, and can be quickly and readily removed for fluoroscopic examinations or other use.

Also, when the device is in place fluoroscopic examination of affected or suspected areas or parts can be made by adjusting the disks I and 8 to bring the desired openings thereof into registration, and by fluoroscopic observation the disposition and the setting of the disks I and 3 canbe observed and can be determined. Through the medium of the disk revolving means 2!, one or both of the disks I and 8 can be revolved, and thus desired openings can be brought into registration, and the two disks can then be moved together to revolve the position of the registering openings and accomplish settings for the serial or seriated sequences of exposures. Either the pawl 32 or 33 can be engaged with the ratchet teeth of the corresponding disk by inward pressure exerted upon the thumbpiece 38 to shove the desired ratcheting bar inwardly, and the ratchet pawls can either or both be moved to inoperative positions by exerting outward pulling force upon one or both thumbpieces 38.

From the foregoing it will be seen that I have provided a multiple X-ray picture seriating device of simple or inexpensive construction that can be used with X-ray equipment of standard type as now installed, and which will permit the production of six exposures upon a single film or sensitized sheet of standard and usual sizes of X-ray film as now commercially supplied for X-ray use, and that the exposures can be serially arranged or located in desired sequence and in position to substantially fit upon and fill the X-ray film in convenient and economical manner.

While I have herein shown and described only certain specific embodiments of my invention and have suggested only certain possible modifications, it will be appreciated that many changes can be made in the form, construction, and arrangement of the parts, and in the materials where specified, without departing from the spisit and scope of my invention.
