Specification of Letters Patent.

Application filed February 15, 1918. Serial No. 217,352.

To all whom it may concern:

Be it known that I, FREDERICK C. TAYLOR, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Portable Projector-Case, of which the following is a full, clear, and exact description.

My invention relates to cases for portable moving-picture projectors. An object of the invention is to provide a simple and inerpensive case in which the lamp housing is movable relative to the case to be within the case when the projector is in transport, and thereby the lamp housing is protected from accidental injury.

Another object of the invention is to provide a case in which when the lamp housing is in operative position the same is outside of the case and, therefore, the heat generated by the lamp in the housing is not accumulated within the case and the films on the rolls arenot subject to the heat and, therefore, to injury from being dried up.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a vertical section through a case embodying my invention, the same being illustrated as it would be when in transport or when the lamp housing is in inoperative position;

Fig. 2, a fragmentary similar section showing the lamp housing in operative position, or when the projector is in use; and

Fig. 3 is a horizontal section on line 3-3. Fig. 2, the curtain being shown in dotted lines.

Referring to the drawings, 4 is the case, preferably rectangular in shape and having a side door 5 through which access may be had into the casing. The door 5 is preferably hinged near the rear end wall 6 of the case. The front wall 7 is provided with a suitable handle 8 to facilitate the handling of the case. The front wall 7 has also an opening 9 over which enters a plug 10, the

plug preferably entering from the outer surface of the wall 7.

The opening 9 alines with a condenser 11 mounted on the rear end wall 6 of the case. A projector mechanism 12 is mounted within the case between the condenser and the opening 9 of the front wall 7. The projector is secured to the side wall 13 opposite the door. The same wall also carries studs H for receiving spools 15 for the film which is to be propelled by the projector mechanism.

A lamp housing 16 is connected pivotally to the rear wall 6 at the lower edge of the opening 17 provided in the case and wherethrough the housing 16 may be swung into or out of the case. A curtain 18 is provided within the case in front of the opening 17 to cover the same when the housing is swung outwardly, as shown in Fig. 2. This curtain is preferably made of two or more hinged sections so that it will fold and, therefore, not interfere with the swinging movement of the housing into the case, as will be seen from Fig. 1. The cur tain also prevents the heat from entering into the case while the lamp is burning within the housing when the same is in operative position, as shown in Fig. 2.

To protect the condenser and retain the lamp housing within the case while the case is in transit, a door 19 is hinged to the rear wall 6 to cover the opening 17 and the opening which exposes the condenser. The lamp housing 16 has an opening 20 which is adapted to aline with the condenser when said lamp is swung outwardly into the operative position, as shown in Fig. 2. A suitable catch 21 is provided on the rear wall for retaining the door 19 in closed position.

It will be noted that the lamp housing 16 is maintained in its operative position under the action of gravity. In the inoperative position it is retained by the door 19. It is prevented from swinging inwardly by the projection 22 provided on the top of the case in proximity of the opening 17.

. From the above description it will be seen that the lamp housing when swung into the case makes the case smooth on all its sides and, therefore, easily transportable, and the danger of injuring any protruding part is Patented ea. 17, rats.

eliminated by this means. Further, the case rear wall and the heat generated therein will have a tendency to dissipate outside of the case, for the heat is battled from the opening 17 by the curtain 18, thereby protecting the film from the heat When using the projector in the case. I claim:

1. A portable projector case including a condenser therein, a lamp housing pivotally connected to the case to swing into the case or out of the case above the condenser in operative relation with the condenser, and IllflIlSfOl locking the lamp housing on its hinge when the same is swung into the case above the condenser.

2. A portable projectorcase having an aperture in the rear wall, a condenser associated with-the rear wall below the aperture, a lamp housing pivotally connected to the rear wall at the lower edge of the aperture to swing into the case through the aperture or out of the case into operative relation with the condenser, a curtain within the case for the aperture, and a door for covering said opening and retaining said lamp within the case. s

3. A portable projector case having an opening in the rear wall, a condenser at the rear wall below the opening, a lamp housing hinged to'the rear wall at the edge nearest to the condenser whereby said lamp can be swung through the opening into the case or out of the case, a sectional curtain in the case for covering the opening, and means for locking the lamp at the opening when the same is swung into the case.

4. A portable projector case having a condenser, a gravitationally-operable lamp houstain within the case over the opening, said curtain being displaceable by said lamp housingwhen the same is swung into the vase, and an outer door for said opening for engaging the lamp housing when the same is swung into the case and prevent the same from accidental movement outside of the case.

6. A portable projector case having a lamp housing mounted to swing into and out of the case, and means for locking the hous-' ing to the case when the same is swung into the case, which is the inoperative position of said lamp housing, said lamp being maintained out of the case in the operative position by gravity acting upon the hous- 7. A portable projector case including a condenser therein, a lamp housing secured to the case to move into the case above the condenser or to be movedout of the case in operative relation with the condenser, and means for locking the lamp housing when the same ismoved into the case.
