`The tubular casing I is grasped by the fingers
`of the operator and the cap 8 is pushed inwardly
`by the thumb or finger of the operator at which
`time the needles 22 will enter or penetrate into
`5 the sterilized gauze or cotton 5 for disinfecting
`or sterilizing the needles. The cap 6 may then
`be loosened and removed and the needles 22
`may be permitted through the action of the
`spring 14 to return to their normal position.
`10 The outer end of the extension 2 is then placed
`against the skin and the casing by being gripped
`in the fingers of the operator may be properly
`held in position whereby a slight pressure upon
`the cap 8 by the thumb or finger of the operator,
`15 will produce a proper acupuncture by forcing
`the needles 22 beyond the end of the extension
`2 for piercing the skin.
`Vlhen it is desired to obtain a strong stimulus
`acupuncture the following method is pursued:-
`The cap 8 is rotated thereby turning the shank
`11 , and the housing I G which carries the needles
`22, and this will cause the collar !!J to be fed for(cid:173)
`wardly upon the external threads upon the
`housing 16 thereby forcing the needles 21 out-
`25 wardly, the collar 19 being held against rotation
`bybeingfreeto slide longitudinally o:f the tubular
`casing I due to the fact that the lugs I 8 will slide
`within the channels 3. The outer housing 2~
`will of course move with the needles 21 longi-
`tudinally of the tubular casing I. The operation
`is contirrned until the outer ends of the needles
`2 ! are in line with the outer end of the line of
`the needles.22. Then by pushing inwardly upon
`the cap !l both the outer needles 21 and the inner
`35 needles 22 will penetrate the skin.
`When it is desired to obtain a medium stimu(cid:173)
`lus acupuncture the cap 8 is rotated until the out(cid:173)
`er ends of the needles 21 project a suitable dis(cid:173)
`tance beyond the ends of the outer needles 22, at
`40 which time only the outer needles 21 may pro(cid:173)
`duce the desired acupuncture. A reversal of the
`rotation of the cap 8 will return the parts to
`the desired position, the inward movement of
`the collar 19 being limited by means of the abut-
`45 ment seat 26.
`From the foregoing description, it will be seen
`that merely by rotating the cap 8 relative to the
`outer tubular casing I, the relative positions of
`the needles 21 and 22 may be adjusted to obtain
`tl1e desired acupuncture.
`Furthermore, by
`means of the structure illustrated the needles 21
`and 22 will be properly braced and due to the
`fact that these needles preferably possess consid(cid:173)
`erable elasticity there will not be a tendency for
`tl1e needles to break even when obtaining an
`acupuncture through hard parts of the skin. It
`should be understood that the needles 21 and
`22 are individually removable from the supports
`in order to permit any individual needle to be
`60 replaced when desired.
`What is claimed as new is:-
`1. A device of the class described compnsmg
`an outer casing, an inner needle carrying hous(cid:173)
`ing mounted within said outer casing, needles
`
`carried by the inner needle carrying housing,
`means for moving said needles longitudinally of
`said outer casing, a series of outer needles
`mounted for movement longitudinally of said in(cid:173)
`ner needle carrying housing, and means for mov-
`ing the outer series of needles longitudinally of
`the inner needle carrying housing for permitting
`the inner and outer series of needles to be se(cid:173)
`lectively as well as uniformly brought into action.
`2. A device of the class described comprising 10
`an outer casing, an inner needle carrying hous(cid:173)
`ing reciprocably mounted within said casing, a
`collar carried by said inner needle carrying
`housing and threaded thereon, an outer needle
`carrying housing carried by the collar, needles 15
`carried by the inner housing, needles carried by
`the outer housing, means for mounting said col-
`lar against rotating movement with respect to
`the casing and permitting longitudinal move(cid:173)
`ment of the collar, and means for rotating the 20
`inner• needle carrying casing for moving sai.cl.
`co118.r and outer needle carrying housing longi(cid:173)
`tudinally upon the inner needle carrying housing.
`3. A device of the class described comprising
`an outer casing, a cap slidably mounted upon 25
`said outer casing, an inner needle carrying hous(cid:173)
`ing reciprocably mounted within said casing and
`operable from said cap, spring means for nor(cid:173)
`mally holding the inner needle carrying housing
`in a retracted position, an outer needle carrying 30
`housing threaded upon said inner needle carry-
`ing housing, means for holding the outer needle
`carrying housing against rotation with respect
`to said casing whereby said outer needle carry-
`ing housing will be moved longitudinally of the 35
`inner needle carrying housing as the in..'1.er needle
`carrying housing is rotated, needles carried by
`the inner needle carrying housing, and needles
`carried by the outer needle carrying housing.
`4. A device of the class described comprising 40
`an outer casing, a cap slidably mounted upon
`said outer casing, an inner needle carrying hous--
`ing reciprocably mounted within said casing and
`operable from said cap, spring means for nor(cid:173)
`mally holding the inner needle carrying housing 45.
`in a reti·acted position, an outer needle carrying
`housing threaded upon said inner needle carry-
`ing housing, needles carried by the inner needle
`carrying housing, neecJJes carried by the outer
`needle carrying housing, said casing having a 50.
`longitudinally extending channel, a lug carried
`by the outer needle carrying housing s1idably
`mounted in said channel for holding said outer
`needle carrying housing against rotation with
`respect to the casing and causing said outer 55
`needle carrying housing to move longitudinally
`of said inner needle carrying housing, the needles
`in each housing being individually removable,
`an abutment seat carried by said casing for
`limiting. the return movement of said housings, 60
`and an extension removably threaded upon the
`outer end of said casing.
