MILTON L. PARRET, OF MARSHALLTOWN, IOWA.

MOVING-PICTUREMACHINE SUPPORT.

To all whom it may concern:

Be it known that I, MILTON L. PARRET, a citizen of the UnitedStates, and resident of Marshalltown, in the county of Marshall and State of Iowa, have invented a certain new and useful Moving-Picture-Machine Support, of which the following is a specification. I

The object of my invention is to provide a moving picture machine support of simple durable and inexpensive construction, having its parts so built and arranged that the moving picture projecting mechanism may be adjusted to a great variety of positions.

, More particularly it is my object to provide a support so constructed and arranged that the lamp and projecting mechanism may be raised or lowered, rotated around a common center or tilted to a variety of po sitions with relation to horizontal for focu ing.

With this and other objects in view, my invention consists in the construction, ar-

rangement and combination of the various 25' parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which: a

Figure 1 shows a side elevation of a moving picture machine support with moving picture mechanisms installed thereon. The machine being a form in which my invention may be embodied. Fig. 2 shows a detailed sectional view taken on the line 2P2 of Fig. 1. 1

Fig. 3 shows. a detailed View seen from the opposite side of that seen in Fig. 1 of my improved support with the moving picture mechanism omitted.

' In the accompanying drawings I have used the reference numeral 10 to indicate generally a tripod or three-legged base having the central vertical hollow sleeve 11.. The lower portion of the sleeve 11, is screwthrea-ded, as at 12, to receive the upper end 7 of a screw-threaded rod 13, which has on its lower end a hand wheel 14. Received in the upper portion of the sleeve 11 is a smooth rod 15on the upper end of which is mounted the frame member 16. Pivotly supported by means of co-acting' ears 17 and 18 and a pintle 19 on the frame member 16 is a table 20 at the rear portion of which is a downwardly inclined member 21, terminating in a rearwardly extending member 22.

l Application filed July 6, 1920. Serial No. 39 1,3205

On the table portion 22 is a plate or the like 23 having spaced upwardly extending parallel ribs 2 1, provided on their opposite outer surfaces with longitudinal grooves 25. The lamp 26 is designed to rest on the table 22, and isprovided near its forward and rearward parts with grooved guide members 27, arranged to slide laterally on and to co-act with the ribs 24 and grooves 25. Supported on the table 20 are the various parts of the moving picture mechanism. 1 have shown the casing 28 for the film handling mechanism, the lens and connected parts, the feed magazine 29 and the takeup magazine 30.

Extending laterally from the table 20 is a shelf 31 shown in Figs. 1 and 2. The shelf 31 supports the motor 82 from which the projecting mechanism is operated. For supporting the table 20 and extension table 22 in various positions of the frame member 16 and for adjusting the supporting mechanism I have provided screw-threaded rods 33 and 84L pivoted respectively to the under side of the table member 22 and to the frame member 16 illustrated in Fig. 3. i

The rods and 3d are arovided, one of them with right hand screw-threads and the other with left hand screw-threads and they are connected by a nut 35 internally screwthreaded with righthand screw-threads at,

Mounted in the sleeve 11 is a set screw 86 by which the upright rod 15 may be locked in any position of its rotary adjustments.

Special attention is called to the cheapness with whlch my moving picture support may be built and to the simplicity of the parts which will not readily get out of order.

lVith moving picture machines generally there is either insufficient adjustability or adjustability is secured by expensive and complicated mechanisms. It will be seen that with my structure herein shown the entire operating mechanism may be easily raised or lowered and accurately adjusted by means of the screw-threaded member 13. The entire mechanism may be rotated by simply turning it around and may be locked the set screw 36. It is also obvious that in any position of its vertical adjustment or rotary adjustment the mechanism supported on the tables 20 and 22 may be tilted to various positions by means of the adjustable nut 35.

The pintle 19 may be removed and the rod 15 may be lifted out of the sleeve 11 for taking the device apart for convenience in packing, storage and tra sportation.

Some changes may be made in the con struction and arrangement of the various parts of my improved supporting moving picture device, Without departing from the real spirit and purpose of my invention and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included Within the scope of said claims.

I claim as my invention:

1. In a device of the class described, a support, an upright member rotatably mounted therein for vertical adjustment, means for effectin such vertical adjustment. a frame on upright, a table pivoted to said frame and projecting therefrom, an adjustable device pivoted to said frame and said table and capable of longitudinal ad.- justment, a plate slidably adjustable on said table, means for locking said plate in different positions of its slidable adjustment, and guides on said plate for permitting, the sliding mounting of a camera on the plate, said plate being arranged to be adjusted toward and from said frame, said guides being arranged transversely of the table.

2. In a device of the class described, a support, an upright member mounted in said support for vertical and rotary adjustment, a frame on said upright, a table pivoted to the upper part of said frame, having a part adapted to be placed in horizontal position, a portion extending downyvardly and away therefrom, and a second portion arranged in a plane parallel With the plane of said first table portion, a longitudinally adjustable member pivoted to the latter portion of said table and to said frame.

3. In a device of the class described, a support, an upright member mounted in said support for vertical and. rotary adjustment, a frame on said upright, a table pivoted to the upper part of said frame, having a part adapted to be placed in horizontal position, a portion extending downwardly and away therefrom, and a second portion arranged in a plane parallel with the plane of said first table portion, a longritudinally adjustable member pivoted to the latter portion of said table and to said frame, said table having a laterally projecting shelf.

a. In a device of the class described, a tripod having a central tubular member, screw-threaded on its interior at its lower portions, a screw-threaded rod received in said screw-threaded portions, and having a head thereon, a smooth rod rotatably and slidably mounted in the upper portion of the tubular member, a frame device on said smooth rod, means for locking said smooth rod in various positions of its rotary adjustment in said tubular member, a table pivoted near one end on said frame device, a longitudinally adjustable brace pivoted to said frame oeviee and said table for ad just-ably tilting said table to different positions of movement.
