To all whom t may concern:

Be it known that I, CHARLES J. KooH, a citizen of the United States, residing fat Cincinnati, in the county of Hamiltonv and State of Ohio, have invented certain new and useful Improvements in Carrying-Cases for Motion-Picture Projectors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

y My invention relates to motion picture projectors and more particularly to a carrying case for portable projecting machines, and the yprincipal object of the invention is to provide a simple, inexpensive and'durable case in which the projecting machine and equipment may be easily carried from place to place, and in which a screen for displaying the pictures is contained in such manner as to permit parts of the case to form the light shield for said screen when in use,

thereby allowing the pictures to be distinctly l displayed in broad daylight.

VViththe foregoing in view, the invention resides in the novel construction and arrangement of parts hereinafter described and claimed, the descriptive matter being .supplemented by the accompanying drawings.

Figure 1 is a perspective viewv of the case and the projecting machine normally carried therein, showing the manner in which a picture may be projected onto the screen within thle case. Y

Fig. 2 is a perspective view showing the projectorhoused within the case in readiness for carrying.

Fig. 3 is a front elevation ofthe case secured in closed positlon. Y Y

Fig. L1 is a vertical transverse section of the case.

Fig. 5 is a vertical longitudinahsection through a portion'of the case on the line 5--5 of Fig. 4.

Fig. 6 is a horizontal section on the plane indicated by line 6-6 otfFig.` 4.

In the drawingsab'ovexbriefly described,

I have shown a case comprising a bottom 1,/ 'a back 2 and ends 3 rising rigidly from said bottom, a movable -front 4, a movable top 5, and a screenl 6. The bottom, ends, back, front and top of the case are all preferabl formed of wood'covered inside and out wit -ber board or other suitable insulating material as shown at 7, and said top is by preference rather deep to provide a pocket 8 for films and other equipment. This pocket may well be closed by a' hinged cover 9 held in normally closed position by suitable tabs and fasteners 10. Both the front 4c and the. top 5 are preferably hinged as shown, but in some forms of the invention they might be rendered removable in other ways.

In the construction shown, the front 4: is hinged at its lower edge for vdownward and forwardswinging and the vertical edges of said front are bound with angle metal strips A11. which project rearwardly to some extent from said front and form flanges bearing against the outer s'ides of the ends 3, at the front edges of the latter. The outer covering 7 of the top 5 depends from said top sufliciently to form flanges '12 which rest against the outer sides of the ends 3 and the front 1, and by means of suitable latches 13, and preferably a lock 14, the top and front may be secured together. Locking these two parts in this manner holds the casing in closed position and allows it to be easily carried by means of a suitable handle 15.

The screen 6 is formed by suitably treating one side of a panel of fiber board or the like, said panel being shown removably held in the rear portion of 'the case by suitable guides 16. When the case is being used for carrying the projecting machine, the panel is reversed from its operating position in order that its screen forming Yside may beprotected against possible injury. It is a simple matter however to remove the panel, turn said panel around, and reinsert it in the guides 16 when the projector is to be used. Y

I have shown a well known form of fold-.- ing projector in Figs. 1 and 2 and in order to properly support such projector in the case, I preferably provide the bottom of the latter with transverse angle metal cleats 17. These cleats equally distribute the strain on the bottom 1 and prevent splitting and warping of the latter. The cleats also prevent forward. bowing of the screen forming panel at its lower end.

The entire .machine may be folded and carried within the improved 4case as seen in Fig. 42 andthe pocket 8 maybe used for films and other equipment. Whenever the apparatus is to be used, the machine is removed from .the'case and set upas in Fig. 1,

' using 'the screen 6 upon which to display the pictures. The rays of light are givenaccess 'best results may be obtained from the` de-y tails disclosed, they may well be followed. I wish'it understood however thatl within the scope of the invention as claimed, the device may be embodied in forms other than that shown. i vl claim: Y

l. A carrying device for motion picture projectors comprising a rectangular case from which the projector'is entirely. removable for use, the front side of said case be ing hinged for downward swinging to admit rays 'from the projector into the case, the

top of said case being hinged for upward swinging, guides in' the back portion of said case, and a panel held by`;said guides and removable upwardly when said ytop is opened, saidjpanel having a screen forming 3.0

sideand being reversible to `protect said side vwhen carryingjthe lprojector within the case.

2. A carrying device for motionpicture projectors comprising a rectangular case from which the projector is entirely nemovable, the bottom of said case having projector -supporting cleats 4 extending from front to back and terminating in slightly spaced relation to the latter, a screen nsert- 40 ed at its lower end between said cleats and the baclgof the casing, and guides for holdi ing the-upper end of the screen in place, said case having a hinged top permitting removal of the screen when raised andalso having a forwardly swinging front to admit lig'ht rays to the screen.

lin testimony whereof I have hereunto `set m hand. i y CHARLES J. KOCH.
