Application-March 27, 1946, Serial No. 657,548

2 Claims. (01. 248-278) This invention relates to reflectors and means for adjusting them, to get the proper reflection.

According to the principle of my invention, I have provided simple adjusting means for accurately adjusting reflectors.

This means relates not only to means for verti-- cal adjustment, but also to lateral adjustment.

I have illustrated my invention by means of a projector, as shown in Fig. l, which throws an image horizontally to a first inclined reflector, which reflects the image, in turn, to a second inclined reflector, which, in turn, reflects the image to a ground screen, or the like.

As will be more apparent hereafter, I have provided a reflector which is hinged at the top, and a screw and knurled nut, which is adapted to press against the bottom of the reflector, for vertical adjustment on the hinge aforesaid.

For lateral adjustment, I have provided another screw, which is adapted to be turned to press against one side of the reflector, to effect lateral adjustment.

I have also provided spring arrangements for the reflectors, whereby, on the threading of the screws in the opposite direction, the springs will cause the reflectors to move in the opposite direction.

Further objects and advantages will appear and be brought out more fully in the following specification, reference being had to accompanying drawings, in which:

Fig. l is a vertical sectional view of the device.

Fig. 2 is a front elevation of the same as viewed from the right in Fig. 1.

Fig. 3 is a perspective of the reflector adjusting means.

Fig. 4 is a vertical section through the adjusting means.

Fig. 5 is a horizontal section on line 5-5 of Fig. 4.

Referring to the drawings in detail, in which I have selected the preferred form for the purpose of illustrating the principle of my invention, I have shown a housing It, containing a projector H and a reflector holder l2, carrying a reflector, which is adapted to reflect pictures upon another reflector l3, which, in turn, is adapted to reflect them onto ground glass M or other translucent screen, as will be readily understood by those skilled in the art.

The holder I2 is hinged, as at l 5, to an adjusting plate It.

The adjusting plate itself is hinged, as at II, to the front wall l8 of the projector.

The adjusting plate 56 is connected by a spring I9 to the front wall iii.

The reflector holder l2 has an ear 20, which is connected by a spring 2| to the front wall l3 of the housing.

zgcond flange 23 bent at right angles to the flange An adjusting screw 21, having a knurled head 25, is adapted to be threaded through the front wall l 8, against the right-angled flange 23, to give movement and adjustment in a horizontal plane.

When the reflector is manipulated by the screw 24, it will turn upon the hinge I 5, as clearly shown in Fig. 5.

In addition to the horizontal adjustment, I have provided for vertical adjustment by a screw 26, also having a knurled head, which is screwed through front wall it and against the adjusting plate l6; and, which, as has been said, is hinged as at H.

The result of this is that, upon screwing the screw 28 in one direction, the adjusting plate It will be moved in one direction, and when the screw 25 is moved in the opposite direction, then the spring IE will pull the adjusting plate IS in the opposite direction also.

With respect to the reflector 12, when it is desired to withdraw the screw 24, then the spring 2! will pull the reflector in the opposite direction.

In operation, When the reflector carried by holder I2 is in properly-adjusted position, the image projected from the projector I l will be reflected by it onto said reflector l 3, which, in turn, will project the image onto the translucent screen 14, the image being suificiently enlarged in traversing the course indicated above. As the projector ll may be removed or replaced as the occasion arises, the adjustments of the reflector carried by holder l 2 enable proper centering of the image on the screen l4, without disturbing the projector ll. By turning screw 25 inwardly, the reflector is tilted so as to project the image onto reflector l3 and accurately center it thereon; and by adjusting screw 26 inwardly, the reflector is moved to adjust the image vertically on The reflector holder also has a flange 22, and a 60 the reflector l3.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variation and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A device of the character described, comprising: a reflector control, including a support; a first element pivoted to move about one axis with respect to said support, and a second element adapted to carry a reflector, pivoted to said first element about an axis at an angle to said first axis; yieldable means normally urging each of said elements in a predetermined direction; and set screws carried by said support and opposing said yieldable means for independently adjusting each of said elements with reference to said support.

2. A device of the character described, comprising: a support; a plate-like member hingedly connected along one edge to said support; a second plate-like member hingedly connected along one edge to a free edge of said first plate-like member, said second plate-like member having means for the accommodation of a reflector; a spring normally urging said first plate-like member toward said support; a second spring normally urging said second plate-like member towardsaid support; a set screw carried by said support and bearing on said first plate-like memher; and a second set screw carried by said support and bearing against said second plate-like member.
