Application sied March 4, 192e. seriai No. 92.159.
This invention relates to improvements-in adjustable reflector frames and consists of the novel construction hereinafter disclosed.
In certain instruments in which an optical systemof lenses and reflectors is utilized for projecting and deflecting light rays, extremely accurate adjustment' of the plane of the reflectors is necessary in orderto center the light Iays. Such a device is shown inIny copending application Serial Number 90,806.
It is an object of the present invention to provide an adjusting means for the reflector frame which will accurately vary the angularity of the reflecting surface so as to'deflect the light ray in a predetermined direction and with a predetermined angle of reflection.
Additional advantages of the construction will be apparent from the following detailed description thereof, taken in connection with the accompanying drawing, in which,
Fig. 1 is an elevation of the supporting plate'for the frame;
Fig. 2 is a reverse view of the plate showing the reflector frame associated therewith; Fig. 3 is an end elevation; V
Fig. 4 is a diagonal section taken on the line 4 4 Aof Fig. 2;
Fig. 5 is an inner face view of the supportf ing plate with the frame removed;
Fig. 6 is a back face view ofthe reflector frame; and
Fig. 7 is a vertical section on the line k7 7 of Fig. 2.
yIn the embodiment of the invention illustrated inthe drawing, the device includes a rectangular plate 1 kprovidedwith openings 2 therethrough for attaching it to the housing of the instrument through which the light rays are, deflected. On the inner face of the plate 1 are lugs 3 arranged in diagonal alinement and offset from a line passing diagonally across the plate from diagonal cor-` ners thereof. The lugs 3 have oppositely disposed notches, or recesses 4 in their upper face which receive opposite ends of a leaf spring 5. The leaf spring 5 is supported byr the lugs 3 so that the major portion of the axis of the plate passing transversely through -a median line thereof. j y
The reflector frame comprises a rectangular plate 6 of somewhat smaller dimensionsy than the plate 1, so that itfmay be free to move within the area bounded by lines pass-y ing through the openings 2.Y The plate 6 has a rectangular recess 7 in its outer face in which the reflector 8. is fitted and held in position by clips9 extending over themarginal edge of the recess and secured to the face of the plate by screws 10 that thread into openings `11 near the marginaledgeof the frame.
On the reverse face of the frame isa lug 12 having achannel 13 therein, into which f the leaf spring 5 fits. The channel 13 isso disposed in relation tothe spring 5 that it bears against the spring on a median line and thefaxis ofthe channel is coincident with the axis of the spring. The lug bearing against the springe constitutes a pivot bearing which, on account of the torque of the spring, affords a fulcrum permitting the adjustment of the face of the reflector along both the major and minor axis of the reflector frame and also on the diagonal axes passing through the oblique corners ofthe frame. It follows, therefore, that the exact degree of angularity of the plane of the reflector may be precisely adjusted in order to deflect the light rays accurately. v
The adjustment is effected through three from the outer face of the plate 1. The screws pass through Openings 15 disposed adjacent to three corners of the plate l, the
openings 15 having a diameter slightly in excess of the diameter of the screws with.
the screws thread into threaded openings 16 alineinent with the openings 15.
in the margin of the reflector frame and in i The screws 14, operating in opposition to the spring 5, afford means for adjusting the reflector frame in respect of the fixedl plate 1 by tilting'the frame to any desired angular adjustment. By properly adjusting the effective length of the three screws, it is ob` vious that the reflector frame may be tilted at the desired angle on both its major and minor axis andupon its Oblique axes, result-- ingin the precise angle of reflection from may be desired. j I am aware thatmy invention may be vInodifie'd in variousparticulars withoutv depart-y ing from the spirity and scope thereof.
the reflecting surface of the reflector that, 'i f 80 Y screws 141, the heads of which are accessible What I claim and desire to secure by Letters Patent is:
1. In u device olfl the class described, a support, a rellector trame, a reflector carried b said frame, a resilient member eccentric- :il/ly arranged in respect to the frame,'a pivot bearing carried by the frame and supported by said resilient member, and screw connections between the support and the frame arranged to operate in opposition to said resilient member, whereby unydesired angular adjustment of Ythe face of the reflector may be effected.
2. A device of the class described comprising a rectangular support, lugs carried by ,said support in oblique alinement and offset from an oblique angle of the axis of the support., a leaf spring carried by said lugs, a rectangular frame, a reflector in said frame, a bearing support carried by `said frame and arranged to connect with said spring, and three adjusting screws being in triangular arrangement operable effectively to rock tlm. frame in respect ot said support to etlect any desired angular adjustment thereof.
3. In a device of the class described, a support, a reflector', a resilient member between the reflector and the support, a bearing connected with the reflector and supported by the resilient member, and adjustable devices between the support and tbe reflector arrano'ed to cooperate in opposition to seid resi ient member whereby any desired angrr lar adjustment of the 'face of' the reflector may be effected.
4. In a device of the class described, a support, an elongated spring carried by the support, a reflector, a pivot connection between the rellector and said spring, and a plurality of adjusting devices arranged.substantially in triangular relationship operable to rock the rellector in respect of the support for adj usting the face of the reflector.
