PICTURE-PROJECTING MACHINE.

Application filed. November 15, 1911.

To all whom it may concern Be it known that I, ALEXA-Nona Funni- NAND Vroron, a subject of the King of Sweden, (having declared his intention of becoming a citizen of the United States) residing at Davenport, in the county oi Scott and State of Iowa, have invented new and useful Improvements in Picture-Projecting Machines, of which the following is a full, clear, and exact description.

My invention relates to apparatus for projecting a picture through a lens on to a screen or curtain where the same is outlined on a greatly enlarged scale and the colors reproduced with accuracy. 1

' More particularly this invention pertains to apparatus for reflecting and projecting plain or colored post-cards aiid the like.

One of the objects of my invention is to construct a machine of this character in such manner that the some is compact and neat in appearance, is easy to operate, and will not readily get out of order.

Another object is to provide means whereby the illuminating agent or lamp may be carried by or contained in the body of the machine, thus obviating the necessity of an additional or separate part to be attached to or removed from the apparatus.

These and other objects I accomplish by .the means and in the manner hereinafter fully described and as more particularly pointed out in the claims, reference being had to the accompanying drawings forming a part hereof.

In the-drawingszl igure 1 is a vertical side elevation of my improved projecting machine. Fig. 2 is a central longitudinal vertical section thereof. Fig. 3 is a mentary horizon'talsection taken on line 3-3, Fig. 1, looking in the direction oi the arrows. Fig. l is vertical longitudinal section, drawn to an enlarged scale, oi one of the carbon-holders employed in connection with my improved machine, and 5 is an end elevation of said holder drawn to the same' scale as Fig. 4.

The housing or casing of my invention consists of longitudinal sides, top and bottom preferably made of select metal tubing 1, that is rectangular in cross-section, and

has its ends closed by ast metal plates 2 and 3. The tubing 1 is clamped between endplate 2 and 8, by top and bottom-tie-rods and 4', but the bottom tie-rods 6, extend "forward beyond the front end-plate and have their forward ends secured by screws to a vertical supporting-frame 18, for the outer stationary tube of the telescopic cylindrical lens-tube 17. The supporting-frame 18., and the rear end-plate 3 are provided with feet l. which support the body of the housing or casing of the machine above the surface upon which the same rests, and thus provide for a circulation. of air beneath the same and enable the air to pass up through openings (4 in the bottom of the tubing 1. These bottom openings a may be covered if desired by false bottom 30, which is raised above the bottom of the housing by downwardly turned integral lugs at its corners that constitute feet, and the upper surface of thi false bottom is polished and assists in the reflection of the light furnished by the carbon-electrodes which will hereinafter more fully appear.

The upper part of frame 18 is secured to and spaced from the front end-plate of the case by the rod 19, substantially as shown in 2 or" the drawing, and it might be observed, in passing, that the other tie-rods hereinbefore referred to areconstructed similarly to rods 19.

The inner tube of the telescopic lenstube is preferably provided at each end with suitable magni'fying lenses, and the underside thereof is provided with a longitudinal downwardly extending rack 24, that projects through a longitudinal slot 23 in the lower portion of the outer tubular element of the lens tube and is engaged by the pinion 25, mounted on spindle 2, which latter is jour naled in suitable hangers or straps secured to and depending a suitable distance below the telescope. Slot 23 extends from frame 18, to end-plate 2, and when pinion 25 is turned in the direction desired by any suitable means, the inner tubular element of the lens-tube can be adjusted longitudinally to obtain the results sought for.

The rear plate 3 has its central area cutaway to provide an opening which is closed l by door 2 hinercd alone .Ls lower opening v 1011 is o latch 8, than opening to in 1 position. noouo if t of $49 door suitable ped cross-section, are soldered or otherwi e secured to the inner no purpose of holdwhile being e1:-

the card or picturehiliited.

The upper part oi? the front end-plate between its upper edge and the telescope lens-tube is provided with a transverse ridge or ss 10, the Walls of Which are pyramidal-- shaped in cross-section, and the "triangular ends of which are arranged in planes at an angle of substantially "forty-five degrees to the front wall of the housing. These ends ave suitable openings therein for the inserlion therethrough of the reduced ends of carlioirholders 11. These holders 11 are subally the 82.3118 in construction, angementand operation as those illustraeed and decribed in a companion application for Patent of the United States for an 'noved electric arc-lamp, executed loy even herewith, filed November 15th, 1911, Number 660,363 and preferably comas a cylindrical-sheped loody portion 12, made of librous insulating material. )lders are hollow and have outer portions than "'lGli' inner ends. is tapped. radially into 7 said holders, and a subally i shaped gu'de plat 15 is secured "min the bore of holders by means 1 uie same screw or 'vet y hat secures the binding-post in position. A eafspring 16 is mounted in inc bore of the wider so that free end will be normally in the crotch *vhen the carbon is in- ,ircuniferentialiy *oy )osii'on of "the axes of e carliat they coi'iverge toward each cir point of intersection or arcpermanent and fixed, and, should formed on the side the same ozn e object being projected,said be reversed and placed in proper relitlon to said object simply rotating or turning the carbons on their own ones by hand.
