EUGENE W. CALDWELL, OF NEW YORK, N. Y.
PORTABLE X-RAY APPARATUS.
I SPECIFICATION forming part of Letters Patent No. 749,813, dated January 19, 1904. i
' Application filed January 16, 1903. Serial No. 139,282. (No model.)
To all whom it may concern.-
Be it known that I, EUGENE W. CALDWELL, a citizen of the United States, and a resident of New York city, in the county and State of New York, have invented certain new and useful Improvements in Portable X-Ray Apparatus, of which the following is a specification, taken in connection with the accompanying drawings, which form a part of the same.
This invention relates to X-ray apparatus, such as is especially adapted for convenient transportation.
In the accompanying drawings, in which the same reference characters refer to similar parts in the several figures, Figure 1 is a perspective view showing one embodiment of this invention. Fig. 2 is a partial front view of the same. Fig. 3 is a similar view showing the parts in their extended position. Fig. 4 is a detail section on the line A 4 of Fig. 1. Fig. 5 is a similar view on the line 5 5 of Fig. 1. Figs. 6 and 7 show several details of construction. Fig. 8 is a diagram showing the electrical connections of this apparatus.
In the embodiment of the invention shown in the drawings the coil-box A is adapted to contain a suitable X-ray coil, this coil being preferably arranged with its core in vertical position, the two terminals of the secondary winding of this coil being provided with heavy insulation, as indicated at B and C. The coilbox is provided with a suitable cover (indicated) which is adapted to inclose the apparatus when the same is folded into the closed position indicated in Fig. 2, and thus protect this apparatus during transportation.
The tube-support in which the X-ray tube is adjustably mounted is firmly secured to the coil-box A. This tube-support preferably comprises the slotted arm A, which is firmly clamped to the coil-box A by any suitable means, such as the wing-nut A which engages the heavy washer A The slot in this arm allows the arm to be slid longitudinally, so as to give it any desired length, the bolt to which the wing-nut is secured sliding in the slot in the arm. At the outer end of this arm a universal joint is formed with the rod A, this rod passing through a suitable opening which is formed in the washers A and A, so
as to be longitudinally adjustable with respect thereto, these washers being preferably clamped together and secured to the arm A by the thumb-nut A At the outer end of the rod the clamp A is pivotally secured, this clamp extending laterally from the rod, as indicated in Fig. 1, and the gripping-jaw A, which is drawn inward by the elastic band A or by any other suitable means, engages the tube and firmly holds it in position, the construction of these parts being indicated in detail in Fig. 5. As that figure shows, the gripping-j aw slides in suitable guides in the clamp, and the band which operates this jaw is adjustably held by a buckle or any other means A It will be seen that this construction of tube-support allows the tube to be so arranged that the source of X-rays is substantially in line with the axis of the rod A. By this means the rotation of the rod about its axis allows for the adjustment of the direction of the rays without materially altering the position of their source.
The two pillars D and E are secured to the coil-box, and the bars D and E of insulating material, are pivotally mounted on the tops of these pillars by the pivots D 'E respectively. The bar D carries at its outer end the conductor-spool D, which is mounted to rotate in a suitable bearing, and by this means the conductor D preferably in the form of tinsel cord or other suitable conductor, may be wound up upon the spool by rotating the same by the pin D. The conductor-guide D is secured to the bar adjacent the spool and is electrically connected with the adjustable regulator D which is mounted on the bar D", so that its movement regulates the length of a series'air-gap in the secondary circuit. This regulator preferably passes through a bar D as indicated, and is provided at its outer end with the regulator-ball D, which cooperates with the ball D mounted upon the bar. The insulating-handle D is hinged to the rearwardly-extending end of the regulator D by a suitable pivot, the construction of these parts being indicated in Fig. 6,.wherethe similar regulator-handle E is pivoted by the pin E to the regulator The coil-terminal B emerges from the insulation B and is connectseries spark-gap which is readily adjustable to vary the action of the apparatus. Since this regulator is connected with the guide D through which the conductor D passes, the high-tension electricity is supplied to the tube A in a regular manner, the conductors D and E on either side being preferably held apart by the spreader A of suitable insulating material. It is of course understood that the construction of the spool-arm E the spool E, and the other parts mounted thereon is the same as has already been described.
The coil-terminal C in the insulation C is given the form of a metallic socket, which is of course connected by a flexible cord with the regulator ball The discharger G which is provided with the insulating-handle C, is movably mounted, so ,as to form an adjustable parallel spark-gap in connection with the terminal B. This discharger is preferably pivotally mounted in the stirrup C the lower end of this stirrup C being removably fitted in the socket C so as to firmly support the discharger. The distance of the end of this discharger from the terminal B regulates the action of the apparatus in a well-known manner, as is indicated by the circuit-diagram shown in Fig. 8.
The parts are indicated in Fig. 1 in their operative extended position, the tube-support being extended and the apparatus being ready for operation in connection with a suitable supply of electrical energy to feed the primary winding of the X-ray coil. The various parts of this apparatus may also be assembled within a very small compass, so as to be placed within the cover of the coil-box,the
regular handles being swung inward against the spool-bars, these bars being folded over into the closed position indicated in Fig. 2, so as to occupy very little room, the conductors having been previously wound up upon the spools D and E. The discharger is removed, together with the stirrup from the socket C and is inserted in one of the compartments F and G, which are formed in the coil-box. The spreader A also fits within these compartments for transportation. The tube-support may be folded after the tube has been removed therefrom into the closed position indicated in dotted lines in Fig. 1. Thus when the cover of the coil-box is closed the whole apparatus is in a compact and convenient form for transportation and the apparatus is so constructed that when in the extended position indicated in Fig. 1 the various parts are so separated and mounted upon their insulating-supports that the proper operation of the apparatus is insured and undesirable sparking and leakage avoided.
It is of course apparent that many modifications .may be made in this apparatus, the
5 proportions and number of parts may be changed, parts of the same may be omitted, and other parts may be substituted without departing from the spirit of this invention. I do not, therefore, wish to be limited to the disclosure which has been made in this case; but
