and permits the installation of such parts within The upper end portion 6 is also a terete or is cylinthe restricted space inside the handle shell. Such drical in transverse section and has its axis disconstruction and arrangement permits the siposed oblique to the axis of the lower major pormultane'ous operation of the switch and the tion 5 as seen in the different views. This upper end portion 6 is hollow, so that it forms an oblique continuation of the lower portion. The interior of the upper portion of the handle provides a guide for a slidable electric socket 1 that carries a light bulb 8 which may be retracted into the end of the handle or may be projected beyond the latter by reciprocating a slide 9 on the exterior of the handle by the operators thumb. These two portions of the handle are made from insulating material, and are preferably a molded hard rubber or a molded phenolic condensation product so that one continuous or unitary hollow piece is provided.
The means for mounting an instrument on the handle is in the form of a universal head consisting of a short tubular base or band l that is telescoped upon the upper end 6 and is removably secured in position by means of a pin I and bayonet slot l2, and, at one side of the axis of the tubular base there is a split band or ring l3 that surrounds the adjacent cylindrical-shaped end portion of the instrument. The adjacent ends of the band or ring terminate in lateral ears l4 that are moved towards and from each other by means of a rotatable cam block l5 that is positioned between them and is actuated by a laterally and radially projecting lever IS.
The split band or ring is of sufficient dimensions to readily receive the cylindrical-shaped rear flange or sleeve portion ll of a speculum H3, and when the cam I5 is rotated this band will become constricted around the sleeve and will firmly hold the speculum, tool or other instrument in position. When an optical instrument such as an ophthalmoscope, retinoscope, etc., is used with the handle the tubular base 0 may be made as a part of such instrument and the clamping band is not needed and the lamp is of a diiferent pattern.
The lamp socket 1 is a metal shell of a diameter to slidingly fit into the upper end portion 6 of the handle and an insulating block |9 is secured in its inner end through which a centrally disposed electric terminal passes. At its inner end this terminal is connected to the adjacent end of a flexible hollow conductor 2| that is made from a spirally coiled or wound wire, shown in detail in Figure 4, which wire coil is surrounded by a flexible protecting sheath 22 of suitable insulating material. The end of the flexible conductor 2| that is remote from the block I9 is attached (preferably by soldering or brazing) to a stiff rod 23 of conducting metal that enters and slides in a small tube 24 also of conducting metal.
An electric terminal wire 25 passes through and projects from both sides of an insulating disklike block 26 mounted within the handle member 5 back of the lower end of the latter, the inwardly projecting portion of the terminal being given a shouldered or S-shaped oil-set bend 29 and secured to the adjacent lower end of the conductor tube 24. This terminal wire 25 is stiff and tightly fits the disk-like block 26 so that a solid mounting is provided for the stationary tubular conductor 24.
A second terminal wire 28 passes through the block 26 with its longer portion disposed within the handle member 5 and having its outer portion projecting into the space between the outer face of the block and the adjacent end of the handle member 5. Thus a suitable electric connector socket is provided at the lower end of the handle for making electric connection through the medium of an electric plug element 29 with a source of current supply. Within the handle and back of the block 26 there is a break formed in said wire 28 by giving it a hump-shaped bend 30, while beyond this bend the wire 28 extends up wardly to near the center of length of the handle grip member 5 so that it is disposed adjacent and parallel with the wall of the handle member to provide a straight contact element 3| that cooperates with a movable member of the switch.
The slide 9 hereinbefore mentioned is positioned over an elongated slot 32 in the wall of the handle so that the slide may be moved longitudinally on the handle within the limits of said slot and such movement is controlled by a lug 33 extending from the slide through the slot to a fiat metal strip 34. The slide 9 and the lateral lug 33 that engages in the guide-slot are pref erably formed integrally from a piece of insulating material such as hard rubber or a phenolic condensation product. Connection is made b tween the slide and the strip by a screw 35 the head of which is screwed in below the surface of the slide and then covered with insulating material, while its shank enters a threaded boss on strip 34.
The bar 34 is one of the elements of an articulated conductor, and at its lower end the bar is curved inwardly as at 36 towards the axis of the handle to slidably engage the contact element 3| above mentioned. As shown in Fig. 5, the curved end portion 36 of the bar is formed concavo-convex so that the portion thereof that engages and slides on the contact 3| will partly surround the latter and insure positive electrical engagement therewith whenever the switch is in an on position and the circuit closed.
The other or upper end of the bar 34 is flexibly and movably connected with a short conductor link or bar 31 by an articulation in the form of a hinge 38, and said short conductor link or bar 31 is likewise flexibly and movably connected by an articulation or hinge 39 with the shell of the lamp socket 1. The terminal wire 28 including the straight contact element 3|, the long bar 34, the short link bar 31, and the hinged articulations 38 and 39 are fabricated from suitable metal capable of effectively conducting electric current. In order to positively insure conduction of current a flexible jump" wire 40 is preferably connected at its ends respectively to the socket shell 1 and the short link bar 31. The other side of this circuit through the lamp is formed by the central lamp socket terminal 20, the flexible conductor 2|, the rod 23 slidably telescoping with the tubular conductor 24 and the lower terminal 25.
When the parts of the structure are in the relative positions shown in Figure 2 the circuit is closed through the lamp 8 and the latter is illuminated and is protruding from the end 01 the handle. Upon moving the slide-piece 9 downwardly on the handle to the other end of slot 32, the curved end 36 of conductor bar 34 (which had previously engaged the straight portion 3| of the conductor terminal 28) will be moved oil! said straight portion and will be positioned free in the space alongside the bend 30, thus breaking contact and opening the circuit, as illustrated in Figure 3. In this latter position 01' the elements the circuit is broken and the lamp is extinguished and will be retracted into the adjacent end of the handle. On account of the articulations 33 and 39 as well as the flexibility of the spiral conductor 2| and the telescopic coaction between rod 23 and the tube 24, these composite conductors that form the circuit from the connector terminals 25 and 28 through the socket shell and lamp, are readily moved longitudinally in the hollow handle 56 and around the angle formed at the juncture between the two obliquely disposed portions of the handle.
It will be noted the lamp will remain lit, although being retracted into the handle, until such time as the bowed end portion 36 of the movable conductor strip is moved out of contact with its coacting contact element 3| and has been disposed free in the recess formed by the bend 30 in said contact element. This permits the lamp to be moved to a position where it will not interfere with instruments inserted in the speculum to operate upon the tissue and will continue to illuminate the cavity during the performance of the operation, and will also permit up and down movement of the lamp with relation to an ophthalmoscope or retinoscope for the purpose of focusing the light with respect to the optical elements of such instruments.
