new and useful Improvements in Adjust able Lamp-Supports. of which the following is a specification.
The object of my invention is to provide an adjustable support for electric lamps of novel, simple and eflicient construction which may be readily adjusted to set the lamp in any desired position.
The invention is particularly for use in connection with dental chairs and surgical tables and chairs: and in this connection my invented device has special advantages in that it is not conspicuous and that it may be quickly adjusted into any desired position for use and also adjusted into a position where very little if any of the device may be seen by the patient. it being well known that mechanical appliances around dental and surgical chairs and tables have a strong tendency to frighten nervous patients.
The invention consists of the elements and the novel construction and arrangement thereof hereinafter fully described and particularly claimed.
In the accompanying drawings. illustrating my invention. Figure 1 is a perspective view showing my improved lamp supporting device applied to a dental chair, the lamp supporting device being shown in full lines and the dental chair being shown in dotted lines. Fig. 2 is a side view of the lamp supporting device removed from the dental chair. Fig. 3 is a section through a portion of the lamp supporting device.
Referring to the drawings, 2 designates a bracket which may be of any suitable shape and size for its intended purpose. As herein illustrated, it comprises an arm 3 having a sleeve 4 formed on one end thereof and a socket 5 formed in the other end thereof. The sleeve 4 is adapted to surround the post 6 of the usual bracket 7 which carries the cuspidor 8 of a dental chair 9, as shown in Fig. l. The sleeve 4 is provided with a set screw 10 by means of which the bracket 2 may be secured in different positions of adjustment upon the post 6.
Fitted in the socket is a ball 11 which is formed on one end of an arm 12. The ball 11 is adapted to be clamped in different positions of adjustment within the socket 5 by a hollow nut 13 having an end wall 14 surrounding and engaging the ball 11. 011 the other end of the arm 12 is formed or secured a tube or sleeve 15 which extends at right angles or substantially so to the arm 12. Slidable longitudinally within the sleeve 15 and projecting beyond the ends thereof is a straight, non-flexible tube 16 which may be secured to the sleeve 15 in different positions of longitudinal adjustment by a suitable set screw .17. Secured to one end of the tube 16 is a part. 18 having a socket therein adapted to receive the connecting plug on one end of an electric battery 19, or to receive an electric connecting plug on the ends of conducting wires, sockets and plugs of this character being common and well known. Secured torthe other end of the tube 16 and forming. in effect, a continuation thereof is one end of a stiff, flexible, metallic tube 20, the other end of which is providedwith a tubular head 21 having a socket 22 formed therein. Fitted in the socket 22 is a ball 23 on one end of a tubular arm 24. The ball 23 is adapted to be clamped within the socket 22 by a hollow nut 25 which embraces the ball 23 and is screwed on to the head 21. on the other end of the arm 24 is a part 26 having asocket therein adapted to receive the connecting plug of a suitable electric lamp 27, the lamp plug and socket being of common and well known construction. The parts 18 and.26 are electrically connected in the usual well known manner by wires which extend through the tubes 16, 20, 21 and 24.
The flexible tube 20 may be bent in any desired manner to adjust'the lamp 27 into the desired position, and, when so bent, the tube 20 is stiff enough to retain its shape and support the lamp 27 in its adjusted position; and when occasion requires, the lam 27 may be adjusted with respect to the flexible tube 20 by moving the ball 23 within its socket 22. By loosening the nut 13, the
interfere with the work of the dentist or ,physician; and, further, by loosening the nut 13, the arm 12 may be turned to invert the tubes 16 and 20 and place the device in an inconspicuous position, in which the tube 16 may be lowered through the sleeve and the flexible tube may be extended back of the chair 9.
By removing the nut 13 from the arm, the arm 12 and parts carried thereby may be readily removed from the bracket 2 and applied to a suitable bracket elsewhere, having a-socket to receive the ball 11 and a screw-thread to receive the nut 13.
This may be readily done for any desired purpose, and, when the arm 12 is removed from the bracket 2, it will be impossible to lose the nut 13, as the sleeve 15 and ball 11 will prevent the nut from being moved from the arm 12.
I claim:
1. In a lamp support, the combination of a bracket,-an arm adjustably connected to said bracket, a sleeve having one side thereof attached to said arm, a tube extending through said sleeve and being longitudinally adjustable therein and having its end portions extending outwardly beyond the respective end portions of said sleeve, a part connected to one end of said tube and having a lamp-receiving socket therein, a part connected to the other end of said tube and having a socket therein adapted to receive tending outwardly beyond the respective end portions, a tube extending through said end portions of said sleeve, a part connected to one end of said tube and having a lampreceiving socket therein, a part connected to the other end of said tube and having a socket therein adapted to receive an electrical connecting plug, and electrical conducting wires extending through said tube and connecting said parts.
8. In a lamp support, the combination of a bracket, an arm adjustably connected to said bracket, a sleevevhaving one side thereof attached to said arm, a non-flexible tube extending through said sleeve and being longitudinally adjustable therein and having its end portions extending outwardly beyond the respective end portions of said sleeve, a part connected to one end of the non-flexible tube and having a socket thereinadapted to receive an electrical connecting plug, a flexible tube having one end secured to the other end of the non-flexible tube, a part secured to the other end of the flexible tube and having a lamp-receiving socket therein, and electrical conducting wires extending through said tubes and connecting said parts.
4:. In a lamp support, the combination of a bracket carrying a sleeve having free open sleeve and being longitudinally adjustable therein and having its end portions extending outwardly beyond the respective end portions of said sleeve, a part connected to one end of said tube and having a lampreceiving socket therein, a part connected to the other end of said tube and having a socket therein adapted to receive an electrical connecting plug, and electrical conducting wires extending through said tube and connecting said parts.
In testimony whereof I aflix my signature in presence of two witnesses.
