Thisinvention relates to projection apparatus, and more particularly to apparatus of the type which is adapted to project either cinematographic films or stereopticon views,
andthe principal object of my invention is to provide new and improved apparatus of this type. In the drawings accompanying this specification and forming a part of this application I have shown, for purposes of il,
' 1 metal and of general rectangular form. Thelustration, one form which my invention may assume, and in these, drawings:
Figure 1 is a side elevation of a projection apparatus embodying the invention w1th one side wall thereof broken away,
Figure 2 is a front rend elevation showing the muzzle in position for displaying stere opticon views; and
Figure 3 is a view similar to Figure 2 showing the muzzle arranged for displaying cinematographic films. a
The illustrated embodiment of the invention comprises a housing 1 formed of sheet front end ortion 2 of the housing 1 is substantially rusto-conical in shape, and extending rearwardly from'the housing 1 are a plurality of adjusting knobs 3 for adjusting the ositions of the mechanism contained-with- 1n the housing for providing an eflicientprojected 1i ht. I p The function of the various adjusting knobs 3will not be described inasmuch as these form no part ofthe present invention.
- The source of light generated within the housing 1 consists of an arclamp having opposed electrodes 4 and'b, the electrode being carried b an upright support 6, and the elec I trodes 5 eing carried by a support 7. The
supports 6 and 7 may be adjusted relatively to each other in any well known-manner so as to effect a light of the required brillianc'y. The are lam also includes a reflector 8 which is horizonta 1y slidable on parallel'rods 9 (onlyone rod being shown), a
In accordance with this invention a muzhousing'l. The muzzle 10" may be of rela- 'tively thin metal and formed by stamping.
To connect the muzzle 10 to the housing 1 a horizontal shaft 11 is rotatably mounted in Application for that the muzzlelO may be swung in a vertical plane .over the opening of the outer end port1on 2 of the casing 1.
To limit the downward movement of the muzzle 10 a lug 14 is formed thereon for engagement with an outwardly projecting pin 15 on the end portion 2. For limiting the upward swin movement of the muzzl and for hold e 10 catch 16 is adapted to engage the pin 15 as indlcated in Figure 3. A handle 17 maybe fixed to the muzzle for enabling the same to be readily moved. i
- The muzzle 10 is provided in one portion thereof with an openin over which fits an outwardly extendin tu ular member 18 secured to the muzzle y screws 19. When the muzzle is swung to its upper position, as
. shown, in Figure '3, the center of the tubular member 18 is substantiall. in line with the electrodes 4 and 5, and in t is position the apding the same in this position, a a
paratus may be used for displaying cinematogra h ic films. Indevices of, this character it is esirable to provide a shutter so that the source of light may be cut oil when desired, and for this purpose a shutter 20 is pivoted at 21 and is When the muzzle 10 'is swung downwardly provided with an operating handle with the stop14 in en a ement with the pin or displaying stereelectrodes 4 and 5, and the light from the are lamp is projected thruthe opening 24 in an indirect manner hereinafter described. a The member 23 is attached to the muzzle 10 by screws 25 disposedin-elon-gated slots 26 so that a'slight lateral adjustment of the member 23 may be made relatively to the muzzle 10. Movable across themember 23 is a slide 27 having a knob 28 at one end so that the slide may be moved to and fro across the opening 24 to display the views carried by the slide.
A reflector 29 is mountedat one sideof the j electrodes 4 and5, and when in operative position is adapted to direct the li ht from the arc lamp' thru the opening 24 in t e member 23 so that stereopticon views may be displayed.
Forthispurposeanopeningis to a screw 37 on the bracket 32. This spring serves normally to hold the reflector 29. in operative position so that the light from the arc lamp may be directed thruthe opening 241 in the member 23.
Depending from the reflector 29 is a pin 38 which is engaged at its inner side by a horizontal rod. 39 carried by a bracket 40 securedby set screws 41 to a shaft .42, and the opposite end of the shaft .42 is connected to a universal joint 43, and the universal joint 43 is connected to the shaft 11 by means of a rod 44 and a universal joint 45.
From the above description it will be seen that when the handle 17 of the muzzle 10 is swung downwardly to the position shown in Figure 2, so that stereopticon views may be displayed thru the rectangular opening 24., the reflector 29 is disposed in operative position relatively to the arc lamp. When it is desired to discontinue the displaying of stereopticon views the handle 17 of the muzzle 1O may be swung upwardly until the catch 16 enand 3) and this movement is transmitted thru' '55- matically moved intoand out ofpositiom-and flector ad acent said source of light, and
gages the pin 15, and in this position the tubular projection 18 is properly positioned relatively to the arc lamp so that the light generated is. satisfactory for displaying cinematographic films.- It will be observed that when the muzzleis swung upwardly the shaft 11 is rotated in a clockwise direction, (Figures 2 the universal joints 45 and 43, rod 44, shaft 42-,
and rod 39, to the depending pin38 of the re-" flector 29. By this movement the pin 38 is engaged and the reflector 29 is swung away from the arc lamp to inoperative position. When the handle 17 of the muzzle is again swung] downwardly the rod 39, through the connections described, is moved away from the pin v housing and. a source of llght withm said housing, a muzzle on the outer end of said 38, and the coil spring 31 therai'ter functions to move the reflector 29 to operative position so that the stereopticon views may be displayed. I
It will be seen that the reflector 29. is auto-.
chine in more or less detail to comply with the requirements of the statute, it is nevertheless described 1 'impr'oved' madesired that this detailed description be considered merely as illustrative, and not as limiting, as it is to be understood that changes and modifications may be made by those skilled in this art without departing from the spirt of the invention, or sacrificing the advantages thereof.
