Application led December 26, 1922. Serial No. 608,934.
To all whom 'it may concern:
Beit known that I, BURNHAM W. KING, a
A citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Magnifiers, of which the following is a specification.
This invention relates to improvements in magnifiers and has particular reference to a combined illuminating device and magnifier which shall facilitate use of the magnifier under adverse light conditions.
@ne of the rincipal objects of the present invention is tle provision in connection with a magnifier of means for illuminating the focal point or area of the magnifier so that the object may be most clearly seen.
A further object ofthe invention is the provision of a device which will accomplish the desired result without undue direct light reflections tending to interfere with the vision.
A further object of the invention lis the provision of a device of this character which may be readily folded when not in use and in which the illumination and the position of the magnifier may be simultaneously controlled. Other objects and advantages ofthe present invention should be readily apparent by reference to the following specification taken in connection with the accompanying drawings, and it will be understood that I may make any modifications in the specific details of construction shown and described within the scope of the appended claims without departing from or exceeding the spirit of the invention.
Figure I is a perspective view of my improved device in use.
Figure II is a side elevation thereof. Figure III is a view of the device packed in a suitable case and adapted for the use of physicians and surgeons, and the like.
Figure IV is a semi-diagrammatic side elevation of a dicrent form or embodiment of my invention.
.sleeve or holder 4 provided with the rojectlng ears 5 between which is pivoted t e head 6 of .the folding shank 7. This shank 7 is provided at its opposite end with a magnilier or lens 8.'
I would call particular attention to the fact that the head 6 is provided with an inclined foot 9 so disposed as when in open position to rest upon and depressthe button or swltch 3 closing the switch or circuit lso that the bulb in the flash-light will be enerl gized and a beam of light projected as at 10. It is further tobe noted, as will be best understood by reference to Figure I, that the angle of the portion 9 with respect to the shank 7 is such that the magnifier lens 8 will be supported with its focal point 11 substantially in the axis of the projected beam 10 so that the area viewed through the magnifier will have a substantially uniform illumination. At the same time the lens is supported at such an angle that the light from the flash-light or source of illumination will tend to be reliected off to one side rather than back through the'magnifier, so that the glare lwhich might otherwise result and interfere with vision, may be avoided.
A device of this character is ca able of many uses, one of which is illustrate ,in that it is shown as employed in lookin at a splinter 12 forced into the finger 13 adjacent the finger-nail 14. Another special use is the examination of jewelry and precious stones, inside of watches or clocks, texture of cloths or Silks, quality of material, examination of' seeds, chemicals and minerals, bearings of machinery to see if worn, castino-s, etc. This is particularly valuable in thls connection to physicians desiring to closely and careful y examine minor injuries, cuts, etc., where it is necessary that the area to be examined be brightly illuminated.
The device is also capable of satisfactory use in eye examination.
The holder for the lens can also be made with the universal joint so the lens can be turned in any direction so as to accommodate its focus to any irregularly shaped object to be examined.
A particularly advantage will be seen in the resent construction in that the handle or ligiit 1 may be grasped in the usual manner when the thumb of the user will naturaly rest upon and hold down the shank 7, thus closing the switch and turuin on .the light, while when the device is laid own Vthe others, the magnifier has its focal point lying substantially in the axis of the pencil of light rays from the magnifier so that the area in focus of the magnifier is properly illuminated.
, In Figure III, I have shown my magnifier as dis osed within a suitable box or container 21 avin the recess 22 into which the battery case or andle and lens fit, and having a supplemental top recess portion 23 to receive the magnifier lens.
1. A device of the character described, the combination with a source of luminosity, of a controlling switch therefor and a foldable magnifierv having a portion actuating the switch as the magnifier is 'shifted into operative relation.
2. A. device of the character described, including a tubular flash-light, a carrier sleeve embracing the light, and means for supporting a magnifier fitted to the carrier sleeve, sald means having an angularly disposed portion for limiting swinging movement of the'magnifier, substantially asv and for the purpose described.
3. In a device of the character described, the combination with a Hash-light, ofa carrier sleeve mounted thereon, a magnifier operatively mounted on-the sleeve and folda'ble against the flash-light when not in use, and projecting therefrom in angular relation thereto when in open position, and means carried by the ma ling the actuation of the ash-light.
4. In a device of the character described, the combination with a flash-light having a projecting control switch, of a carrier mounted thereon adjacent the switch, and a magnifier on the carrier having a portion for engagement with the switch to hold 'the latter in closed position.
5. The combination with a handle of a flash-light which is adapted to fiash a longitudinal beam of li ht, of a magnifier includin a frame wit a supporting shank, a ban telescopically fitting said flash-light ifier for controland on which the supporting shank is carried the shank being ivotally connected to the band, through w ich the Hash-light slidably passes, so that together with the pivotal action of the frame, the focal point from the magnier lens may be adjusted relatively to an object which is free and unattached with regards to the flash-light and is substantially on the axis of the rojected beam of light, and means carried) by the pivotal end of the shank to abut with the wall of the flash-light to limit Athe magnifier in an operative position.
