Definitions

  • Such lamps are not usually provided wlth ventilating means and therefore produce excessive heat to the discomfort of the person undergoing treatment and even danger to the lamp structure itself.
  • a further and particu arly important fea; ture of the invention isin the provision of a reflector having its walls shaped in accordance with empirical formulae, proven by experience to be satisfactory for the purpose designed.
  • Another purpose is to produce means for causing a circulation of air through the reflector whereby superabundant heat is removed from its interior.
  • Figure 2 is a top plan view of the same.
  • Fi ure 3 is a sectional view of the reflector and 1ts dome, drawn to a greatly enlarged scale. 7
  • Figure 4 is a transverse sectional view taken on line 4-4 of Figure 3.
  • Figure 5 is a fragmentary top plan view of the structure.
  • Figure 6 is a fragmentary sectional view taken on line 66 of Figure 3..
  • Figures 1 and 2 are shown an upright 10, the same being one of the elements of any suitable stand and having slidably engaged upon it a sleeve 11 provided with a serrated lateral lug 12 to engage a mating member 13 clamped by the knob 14 when in adjustment.
  • J Y b An arm 15, integral with the member 13, and movable into angular positions as indicated by the broken lines in Figure 1, has formed on its Outer end a so ket 16 in which is rotatably received a stem 17 provided with v a clamp nut 18, easily accessible by reason of the socket being oflset from the arm, and by which the stem may be fixedly held in any position it may be rotated into.
  • a fork 19 pivotally supporting a cylindrical dome 20 and capable of being clamped in adjustment thereon by screws 21, this dome engaging a reflector generically designated 22.
  • an electric light bulb 23 preferably approximately 1000 watt capacity, fed by current conducted by a cable 24'passing out of the top of the dome and provided with a switch 25, the conducting cable being attachable to a wall plug as shown in Figure 1.
  • the reflector 22 which is preferably about eighteen inches in diameter at its base, is composed of a single sheet of highly polished metal, aluminum being preferred, and consists of a lower cylindrical band 30 of a certain width having a beaded bottom 31 and at the top anadjoining'surface 32 disposed at an angle of forty-five degrees.
  • a short cylinder 33 connects with an angular step 34 of 4142', other similar steps 35 to 42, ten in' all, inclusive being positioned at respective angles, approximately 38-30', e5 a', 31 -45, 27 -59, 2a-42', 1941', 1432 and 821 from. a straight line subtended horizontally from the axis of the reflector.
  • a series of short cylindrical connections are interposed between each adjacent angular step, these connections being decreased in length progressively from the lowest 33 t0 the highest 44 as can best be seen in Figure 3.
  • focal point X of the lamp 23 is central of the reflector and at a point midway in the height of the lowermost angular step 32, whereby the light, and also the heatrays, from this point striking the polished inner surfaces of the several angular steps, 32 to 42 inclusive, are reflected, perpendicularly outward through the base of the reflector, as clearly indicated in Figure 3.
  • a correspondingly bevelled flange 45 held in position by bolts 46 having spacing collars 47 therebetween, this flange depending from the cylindrical wall 48 of the dome 20, the same being open at its bottom into which the flanged opening 43 projects.
  • the top of the dome terminates in a raised convex crown 49 having a central opening 50 for connection with a cable support, and through the wall of the crown are several openings 51 for ventilation.
  • louvers 52 and 53 Other means for ventilation are supplied by louvers 52 and 53, in which the wall of the cylinder 48 is sheared transversely at several points in the circumference and then the metal below bent inwardly for the three lower openings 52, the upper openings 53 being reversed, this arrangement causing a pronounced draft complete circulation from within the reflector.
  • a therapeutic lamp reflector having a generally parabolic shape composed of a beaded cylindrical lower element, a series of ten bands presenting faces disposed from the bottom to the top progressivel at approximately the following ang es: 45 4142', 3 -30, 35 -3, ar -45', 27- 59', 23 4.2, 19 41', 14-32,
  • a therapeutic lamp reflector having a generally parabolic shape, a series of bands presenting faces disposed from the bottom to the top progressively at approximately the following angles: 450, 4142', 3830', 35 -3, 31 45', 27 59', 23 42', 19-41, 14-32, 8-21', all of said angles being subtended from the axis of the reflector and cylindrical bands connecting said angular bands.
  • a therapeutic lamp reflector having a generally parabolic shape, a series of bands presenting faces disposed from the bottom to the top progressively at predetermined decreasing angles, the initial angle being 45-0, all of said angles bein subtended from the axis of the reflector, an cylindrical bands connecting said angular bands, said cylindrical bands decreasing in width from the lowermost to the uppermost.
  • a therapeutic lamp reflector having a generally parabolic shape, a series of bands presenting faces disposed from the bottomto the top progressively at predetermined decreasing angles, all of said angles being subtended from the axis of the reflector, and
