Specification of Letters Patent.

SUPPORT.

Patented June 19, 1917.

To all whom e't may concern:

Be it known that I. Anonrn F. GALL, a citizen of the United States, and a resident of West Orange, Essex county, New Jersey, have invented certain new and useful Improvements in Supports, of which the following is a description.

My invention relates to supports and more particularly to a su port or table of an improved type which 15 especially adapted for use with rejecting machines, and which is designed or such adjustment as to render it possible to eii'ect changes in the osition of a projecting machine or other evice supported thereby.

The principal object of my invention is to provide a firm and substantial supporting device of this character, which, w 1 e of simple construction, is capable of such adjustment as to cause a projecting machine carried thereby to display ictures in proper position on a screen when t e projecting machine is located either in a position directl in front of the screen orabove or below suc position.

A further object of the invention is to provide, in a device of this character, improved means for mounting the. lamp house of a moving picture. machine whereby it will be possible to easily and quickly move the lamp house laterally out of operative position with respect to the head of the movin icture machine to permit repairs or a ustment of the head and to prevent destructive action of the heat emanating from the lamp on the moving picture film when the latter is not being fed through the machine, and so that the lam house can be operatively positioned wit respect to the usual stereopticon lens (not shown) for the display of lantern slide pictures on the screen.

Other objects and features of my inven= tion reside in the construction of parts and combinations of elements hereinafter more fully described and claimed.

While my invention may be embodied in various forms, the preferred form is shown by way of example in the accompanying drawing forming a part of this specification, and in which:

Figure 1 is a side elevation, partly in section, of an embodiment of my invention as used in connection with a moving picture machine;

Fig. 2 is a plan View of the supporting device shown in Fig. 1, parts being omitted and parts being broken away in order to show more clearly certaindetails' of the device;

Fig. 3 is a transverse sectional view on line 33 of Fig. 1 looking in the direction of the arrow, with parts, in the rear of the plane on which the section is taken, shown in section;

Fig. i is a transverse Sectional view on line 4=4 of Fig. 1 looking in the direction of the arrow, parts being omitted, and the bracket and hand wheel cooperating therewith being shown partly in section;

Fig. 5 is a transverse sectional View on line 5 -5 of Fig. 2 looking in the direction of the arrow; and I Fig. 6 is a sectional view on line 6-6 of Fig. 1. y

In all the views, like parts are designated by the same reference characters.

My improved Support comprises a base having two horizontal side bars 1, supported at their ends by legs 2, and secured in properly spaced parallel relation adjacent their ends by means of the transversely extending bolts 3. Also forming apart of the base and fixed to the bars 1 substantially midway of their length is an upwardly extending bracket 4 comprising converging side pieces 5, joined at their upper ends to form a bearing portion 6 and the transverse connecting webs 7 and 8. Preferably, bars 1, legs 2, and bracket 4 are formed integrally as a casting. Alined openings 9 are provided in the bearing portion 6 and the transverse webs 7 and 8 of the bracket, and a vertical screw threaded rod 10 is. slidably mounted in said openings. A hand wheel 11 having a screw threaded opening 12 is threaded on the rod 10 and rests on the flat upper surface of bearing 6 of the bracket. Obviously, by turning hand wheel 11, the rod 10 may be vertically adjusted in the bracket.

Secured to the upper end of the rod 10 is a yoke 13 in the arms 14 of which is seecured a' transversely extending pin 16. A flat bed plate 17 is pivotally mounted on the pin 16 secured to yoke 13 by means of a depending lug 18 formed integrall with the bed plate substantiallymidway 0 its length and provided with an opening in which the pin 16 is received.

The bed plate 17 is provided at each of its ends with a lugs 19, to which are pivotally connected by means of a bolt 20 two rods 21. The rods 21 each telescope in a hollow rod 22 which is provided with a longitudinally extending slit 23. The rods 22 at each end of the bed plate are connected adjacent their upper ends by transverse webs 24, preferably formed integral therewith, and which are provided with longitudinal openings extending therethrough. The ends of each web 24 terminate adjacent the slits 23in the pair of rods 22 which the web, connects, and

on the opposite sides of these slits 23 are formed lugs 26 having openings 27 in alinement with the opening25 in the web 24. Bolts 28 pass through the alined openings in the lugs 26 and webs 24 and are provided at one end with nuts 29. It will be apparent that by turning nuts 29? the rods 22 may be clamped to the rods 21 to hold the latter in any adjusted position with respect thereto.

Each pair of rods 22 at the ends of the support are connected at their lower ends by means of a web 29 preferably formed integrally therewith, which web is provided with a laterally extending portion 30 having shoulders 31 at its opposite ends. The extending portion 30 of the web is pivotally secured to the base of the table or support by means of a vbolt 32 which extends through an opening in portion 30 and alined openings 33 and 34 in the side bars 1.

The wall of the opening through the laterally extending portion 30 of each of the webs 29 is slitted as at 35, and on opposite sides of the slit, lugs 36 are formed. A bolt 37 passing through alined. openings formed in said lugs and a nut 37 on the bolt provide means'by which the web 29 may be clamped to the bolt 32 in any adjusted angularposition with respect thereto.

Secured to the under side of and at one end of the bed plate 17, as by means of ,mgans of flanged rollers 44 rotatably mountpair of depending spaced the rods 40, as shown in Fig. 2 of the drawings.

Secured to the plate 43 is the lamp house 47, the plate 43 acting as a carrier for the lamp house, through the engagement of its rollers 44 with the rods 42, to' convey the same into or out of operative position with respect to the head 48 of the movingpicture machine. Reference character 51 represents a handle secured to the plate 43, whereby the latter may be shifted laterally on the track formed by rods 42. The head 48 is secured to the bed plate 17 at the end thereof opposite the, end to which plate 38 is secured. While the moving picture machine may be manually operated, I preferably provide an electric motor 49 suitably supported from the under side of the bed plate 17, which is adapted to operate the film feeding mechanism of the head 48 by means of suitable power transmitting mechanism, such as belts 49 and pulleys 50.

For the purposes of the invention, it will be apparent that, on loosening nuts 29 and 37, the bed plate 17 may be vertically adjusted by turning hand wheel 11 and may be angularly adjusted about a horizontal axis nection with rod 10. After the bed plate 17 has been so adjusted as to locate the moving picture machine, or other device carried thereby, in the desired position, the same may be firmly held in such position by tightening nuts 29 and 37. An improved construction, which is specifically described above, is also provided for supporting a lamp house on the bed plate 17 for lateral movement with respect thereto, whereby the same may be readily moved to or from its operative positions for the purposes herenbefore set forth.

Having now described my invention, what I claim as new and desire to protect by Letters Patent is as follows 2- 1. In a support, a base, a bed plate, means pivotally connecting the bed plate and the pivoted ing in which and means for locking the element mounted onsaid base in adjusted angular position relative thereto, substantially as described.
