Specification of Letters Patent.
Patented July 26, 1921.
Application filed January 12, 1920. Serial No. 850,767.
To all whom it may concem:
Be it known that I IwAN SERRURIER, a citizen of the United States, residing at Altadena, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Picture- Projecting Apparatus; 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 appertainsto make and use the same.
This invention relates to picture-projecting apparatus.
he main object of this invention is to provide certain improvements in pictureprojecting devices such as especially designed for showing pictures in parlors and other small rooms or limited spaces, these improvements being of such character that renders the apparatus especially convenient in preparing the apparatus for operation, and also renders the apparatus especially convenient in preparing it for transportation or storage.
Other objects and advantages are pointed out or implied in the following details of description in connection with the accompanying drawings in which:
igure 1 is a side elevation of a pictureprojecting apparatus including the present invention, a portion of the cabinet being broken off, and one door being omitted.
Fig. 2 is a top plan view of the picture projecting apparatus embodying my invention.
Fig. 3 is a horizontal sectional View, the iection being taken along the line 33 of Fig. 4 is a view similar to Fig. 1, but embodying a modified form of the invention.
Fig. 5 is a top plan view of the apparatus shown in Fig. 4..
ig. 6 is a horizontal sectional view, the iection being taken along the line 66 of Fig. 7 is a perspective view illustrating a form of hinge or pivotal connection embodied in the modified form shown in Figs. 4 and 5.
Referring to these drawings in detail, in which similar reference characters correspond with similar parts,'and in which the projecting lantern l, film-reels 2 and 3 and support a for the film-reel 3 may be of any ordinary or preferred form, the invention consists in the structure hereinafter specifically described and claimed as follows:
Referring now to the form shown in Figs. 1, 2 and 3,- a cabinet 5 is provided, on which the members 1, 2, 3 and 4 are removably secured by any appropriate means, said cabinet being provided with two main compartments 6 and 7, respectively, doors 8 and 9 being provided for closing these compartments respectively if desired. The compartment 6 is sub-divided by means of shelves 10 on which the be placed, together with other accessories, for storage within the cabinet if desired.
he compartment 7 is adapted to receive the screen upon which the pictures are proj ected, together with an improved collapsible bracket onscreen-support which will now be described as follows:
A pair of straight apertured bars 11 and a pair of bent apertured arms 12 are secured together by means of rivets which extend through the end portions of these bars, and a bolt or rod 13 which extends through the apertures at the middle portions of the bars 11 and 12. The rod 13 may be screwthreaded throughout its length, and nuts 14 may be seated on the rod 13 and ti htened against the outer surfaces of the a utting middle portions of the bent bars 12. It will be seen, therefore, that the rod 13, nuts 14 and rivets 15 cooperate with the bars 12 in securing the bars 11 in a fixed spaced relation to one another, at the same time crossbracing these bars 11 so as to form a rigid frame-structure. Beyond the rivets 15, the bars 11 are apertured at both ends, and the apertures at corresponding inner ends of these bars constitute pivotal connections through which studs or pivots 17 extend for movably securing this supporting framestructure, to the cabinet 5, it being noted that the inner ends of the bars 11 extend into the compartment 7, and the studs 17 may either be secured in the apertured inner ends of the bars 11 or secured to the cabinet and extend through these apertured ends. In either event, the bars 11 are provided with pivotal connections within the compartment 7 and may be swung downward into the position shown in dotted lines. It will also be seen that the screen 16, having pivotal connection at 18 with the outer ends of the bars 11, may be collapsed with relation to the bars 11 and stored within the compartment '7, and the doors 9 may be closed and locked for securing the screen and its sup port within the cabinet. A collapsible supporting-brace for the screen-supporting frame is pivoted to the latter by means of the projecting ends of the rod 13, and this supporting-brace comprises two bars 19 and 20 pivotally connected at 21, the bar 20 being pivotally connected at 22 within the compartment 7, and a. shoulder 23 isprovided on the bar 20 to limit outward movement of this bar about the pivot 21. Although but one supporting-brace 1920 has been specifically described, it is to be understood that there are two of such braces, one on each side of the screen-supporting frame. Although the shoulders 23 limit the outward movement of the supporting-bars, the latter may be moved inward or collapsed with relation to one another and to the screen-supporting frame, and when thus collapsed, they are stored, with the screen-supporting frame and screen within the cabinet. A palr of collapsible braces 24 are pivotally connected to the screen at 25 and to the supporting-frame structure at 26. These braces 24 are similar to the braces 19-20 and are adapted to hold a screen in a vertical position for use, and to be collapsed for permitting the screen to be folded upon the supporting-frame.
Referring now to the modified form shown in Figs. 4 to 7 inclusive, it will be seen that the screen 16 and its brace 24 are of substantially the same construction as reviously described in connection with igs. 1, 2 and 3, the bent bars 12, the rod or bolt 13 and nuts 14 being constructed and arranged as previously described. However, the bars 11 are slightly different from the previously described bars 11, the pivotal connections or apertures through which the studs 17 extend being preferably elongated or wedge-shaped, as shown at 17 in Fig. 7. The pivots 17 are each provided with a lateral projection 17 which is wedge-shaped and of a size to conform to the wall of the aperture 17 so that these elements 17 may pass through the apertures 17 when the bars 11 are depending from the pivots 17 or in a vertical position. However, when these bars are in the horizontal position, the projections 17 serve as abutments to prevent lateral displacement of the bars. The pivots 17 are preferably secured to plates 17 which are provided with apertures for receiving screws whereby they are secured to the wall of the cabinet.
In this modified form of the invention, a Y-shaped brace 19*"- has its bifurcated end pivotally connected to the screen supporting frame by means of the nuts 14, the other end of this member 19 being normally seated in a socket 22 which is secured on the cabinet.
Moreover, in this modified form, the cabiopens net 5 is provided with but one door which is indicated at 8 and the compartment 7 is substantially the same as the compartment 7 except that it is closed by the door 8 instead of doors 9, and this compartment on the same side of the cabinet as the compartments 6, whereas, in the cabinet illustrated in Fig. 1,the compartments 6 and 7 open at differentsides of the cabinet. In this modified form, when it is desired to store the screen and its support, the brace 24 is collapsed while the screen 16 is folded upon its supporting-frame, and now, the brace 19 is removed or swung about the pivot 13 so that the bars 11 may be swung downward for permitting them to move laterally out of engagement with the pivots 17 lVhen disengaged from these pivots, it may be placed within the compartment 7 as indicated in dotted lines in Fig. 4.
Although I have described this embodlment of my invention very specifically, it is not intended to limit this invention to these exact details of construction and arrangement, but changes may be made within the scope of the inventive ideas as implied and claimed.
I What I claim as my invention is:
1; A device of the class described, comprising a cabinet and a moving picture projector supported on the top of said cabinet, said cabinet having a compartment adapted to contain moving picture projector parts and supplies and another compartment adapted to contain a screen, a screen for reception in said other compartment, and means connecting said cabinet and screen to space the screen outwardly from the cabinet and dispose said screen in axial alinement with the projector lens for use.
