PROJECTING APPARATUS.

Application filed September 16, 1911.

- To all whom it may concern:

Be it known that I, ZENO LITTMAN, residing in New York city,in the county of New York and State of New York, have invented certain new and useful Improvements in Projecting Apparatus, of which the following is a specification.

This invention relates to projecting apparatus, and more particularly to apparatus of the magic lantern or stereopticon type, the

' cardinal features of this type being common in the art andcomprising, broadly, a lens, a transparent or opaque lmage to be projected, and lighting means toaccomplish such projection.

The prime object of this invention is to provide an improved apparatus for attain ing the ends and objects set forth in an application for improvements in projecting apparatus, filed by Arthur G. Previn March 7, 1911, Serial Number 612,881.

One of the objects is to provide a machine wherein the mechanisms are simple, compact and easy to operate.

Another object is to provide, in embodiments wherein certain factors to be projected move in predetermined paths of travel, as in the present instance, viz., the reproduction of a game of base-ball, mechanisms for controlling the movements and positions of one or a plurality ofanch factors, in addition to the mechanisms for controlling the movements and positions of a ball fact-or.

Another object is to so group all the necessary mechanisms for the reproduction aforesaid that the same may conveniently be removed from a stereopticon. of the usual type, so that the latter may conveniently and'interch'angeably be used for either the usual style of project-ion or the special projection aforesaid.

- Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts, the scope of the application of which will be indicated in the following claims.

' Referring now to the accompanyingdrawings, wherein, is shown an illustrative embodiment of this invention, Figure 1 1s a side elevation of a stereopticon containing an embodiment of my invention, wherein there is also shown, in dotted lines, auxiliary devices, for use when the said stereopticon is used for the old type of slide; Fig. 2

in the direction of the arrow; Fig. 5 is a sectional view, taken on the line w-'w of Fig. 2 and looking in the direction ofthe arrow; Fig. 6 is a plan view of certain parts shown in Fig. 2, illustrating a possible different construction.

Similar reference characters refer to similar parts throughout the several views of the drawings.

Referring now to the embodiment of this invention herein disclosed, 1 indicates a light-containing receptacle, of the usual type. It is here provided with a front-plate 2, terminating in sleeves 3, each carrying a set-screw 4. Slide-rods 5, fastened to baseboard 6, are encircled by sleeves 3, and are firmly fixed thereon at predetermined points by means of set-screws 4. Legs 7, fastened as shown to base-board 6, in combination with sleeves 3 and slide-rods 5, constitute a firm support for light-containing receptacle 1. Pins 8 support condensers 9, which are taken on the line e-a of Fig. 1 and looking in addition restrained by means of plate 10, r

the latter terminating in a sleeve 11 on said rod 5. Plates 2 and 10, as indicated by dotted lines at 12, are provided with circular openings so as to permit light from receptacle 1 to be unimpeded in passing through said condensers.

Omitting for the minute a description of the intervening parts, which in this embodiment constitute an integral machine for removal from the stereopticomlet us pass directly from plate 10 to plate 13. Plate 13 terminates in a sleeve 14, which, with its setscrew 15 is capable of being fixed at any desired point upon rod 5. Between plate 13 and plate 16, thelatter equipped with sleeve and set-screw as is plate 13, is carried the bellows 17. 18 and 19 are the focusing memthrough the operation of focusing screw 21. Referring now to the integral machine mentioned in the preceding paragraph, 22

bers for the lens 20, adapted to be focused is the main-plate thereof. Plate 22, upon I tegral machine inv its entirety from said stereoptico'n. Plates22 carries upon its opposite face the parts now to be described.

The parts so mounted upon plate 22 will be described in the following order: first, those shown in Fig. 4, next those shown in Fig. 3, and next those shown in-Fig. 2: the parts shown in plan in any or all of said Figs. 4, 3 and 2 being shown: in section in Fig. 5 when possible and in elevation in Fig.1 when possible.

Referring now to Fig. 4 (in accordance witlr the preceding paragraph) there is shown'a set of levers 24, 25, 26 and 27. Lever 26 has a branch. 28, carrying thereon a ring 29,- wherein is set a glass 30. Lever 25, terminates in an index-point 31; said lever being further provided with an operating handle, terminating in an auxiliary handle 33. 'l he entire set of levers is mounted upon plate 22, as shown, by means of screw 34, passing through washer 3-5. An orifice 36 is shown in dotted lines behind glass 30, and in the center of said glass and directly over the center of said orifice,

'is shown a symbol 37 (in this instance a base-ball). Orifice 86 is provided to leave unimpeded, as is shown more clearly in Fig. 5, the light-way of the rays from lightreceptacle 1. The construction and design of the levers is such that symbol 37 will have corresponding and pro ortional movement with the movement 0% index 31; the chart 38 in dotted lines having a direct relation to a chart projected by the machine upon the screen (tide chart 39, Fig. 8, herei'nafter described). Pins 40 are set in plate 22 torestrain'any opaque portion of ring 29 from coming within the light-Way area.

- Blocks '41 are set upon plate 22, for the purpose of supporting additional parts,

which are not illustrated in this figure but which will be immediately taken up in the next paragraph. I

Referring now to Fig. 3 (in accordance with the second preceding paragraph), plate 42 is shown mounted upon blocks 41 (Fig. 4). Transversely' thereof, plate 42 is. provided with a plurality of parallel slideways 43 as shown. Each of these slide-ways is adapted to receive an indicating member 44, here shown as being of translucent material and having a name" written thereon and being provided with an operating lip or the like 45. These are adapted to slide back andforth, into and from the lightway area aforesaid (platei42 being provided as shown with an orifice which registers with orifice 36 shown in Fig. 4), in order to project. additional information upon the screen, ulchfas, the .score by'innings, man at hatfi ind:ica tions,'fetc. Mounted upon saidplate42 'is second plate 456,11 shown screws 47 being provided to attach plates 42 and-46 to blocks 41. Plate 46 is, as shown, provided with an integral upper cylindrical portion 48, for the accommodation of parts hereinafter to be described. Plate 46, within the base of said portion 48, as shown, is provided with a substantially square opening 49 the length of one of the sides of which is substantially equal to the diameter of'the circular orifices therebe-. neath. )Vithin this opening 49 is provided a square of translucent material 50, upon which is adapted to be marked any image which it is desired to permanently project, such as, for instance, the chart 39, hereinbefore mentioned in connection with the description of the set of levers illustrated in Fig. 4. This plate or square 50 is maintained in place by means of the parts justrefcrredto which are accommodated in portion 48. Members 51 are shown in their entirety in Fig.2, and will be described when that figure is reached. These members are fastened as shown at 52, Figs. 2 and 3.

Referring now to Fig. 2 (in accordance with the third preceding paragraph), the portion 48 of plate 46 is shown as accommodating the parts hercinbefore referred to. As illustrated in this figure, there is a fixed restraining ring '53, held in placeby screws 54, and slip-ring 55, operable through operating handle 56, slip-ring 57, operable through operating handle 58, slip-ring 59, operable through operating handle 60, and slip-ring 61, operable through operating handle 62. Fixed ring 53 and slip- rings 55, 57, 59 and 61 are more clearlyillustrated in section in Fig. 5, and operating handles trated in elevation in Fig. 1. From Fig. 1

it will be seen that-each operating. handle is in this instance comprised of a fixed rod, a cylindrical member for longitudinal reciprocation therewith, said'cylindrieal-memher being knurled or'roughened on the outer surface thereof and having a pointed upper portion, and an expansile springmounted within said cylindrical portion andbearing at one end against the end of said rod. For example, operating handle 62' "is drawn partly broken away, upon which 62*.is the fixed rod, 62 is the cylindrical member, and 62 is the spring. Mounted upon, plate 46, is a spider 51, having substantially U- shaped arms as shown, and being mounted upon said plate as at 52. Spider 51 has a central orifice as Shown, within which is tact with plate 10 as illustrated in Fig. 1.

The U-shaped spider arms are as shown four in number, marking off quarter-circumferences for the respective slip-rings above mentimed; and are provided with holes 66, each i that slip-ring 59 is fixedly connected to a glass'holding ring 59, and that slip-ring 61 is fixedly connected to a glass-holding ring 61. Each of said glass-holding rings, when revolving with its appropriate slip-ring, carries with it a glass 64. Referring again to Fig. 2 it -will be seen that each glass 6 1 carries thereon a symbol 63 (in this instance supposed to represent the base-running factors in a game of baseball). These sym bols are so placedon glasses 64: that whenever operating handles56, 58, 60 and 62 are all'in latch under any one of the arms of spider 51,.then these symbols are all superposed and over some base-point of the diamond shown at 39 in Fig. 3. This is preferably accomplished by placing symbols 63 in such a manner that their distance from the center of any glass 6% (a0, Fig. 2) is equal to the distance from any base-point to the center of the diamond shown at 39 in Fig. 3.

Referring now to Fig. 1, there is shown, mounted upon focusing member 19, a hinge 67, carrying a lens-holder 68, provided with a tinted lens 69. Fixedly connected to said lens-holder, as shown, is a finger or operating-bar 70. lVhenever it is desired'to cast a tinted glow over the matter thrown upon the screen, for thepurposes of scoring or additional significance, it is merely necessary to press with the finger the bar 70, whereupon the transmitted light from lens 20 will have to pass through and be tinted by'lens 69;

Having described the parts above, let us refer now to Fig. 6, wherein is shown a portionof Fig. 2, to-wit, portion 48 of plate 46, fixed ring 53, screws 54, and slip- rings 55, 57, 59 and 61, all precisely as shown in Fig. 2. Spider 51 is also shown, but with, onlyone U-shaped arm instead of four; and this difference,as well as the provision on slip-ring 55 of operating- handles 56, 56

and 56 in' addition to the operating-handle 56, on slip-ring 57 of operating- handles 58, 58 and 58 in addition to the operatinghandle 58, on slip-ring 59 of the operatinghandles 60 60 and 60 in addition to the operating-handle 60, and on slip-ring 61 of the operating-handles 62, 62and 62 in addition to the operating handle 62, constitute a second illustrative embodimentrofthe feature of this invention designed to show the base-to-base movements and positions of certain factors in the event reproduced. The device shown in Fig. 2 for showing said factors is operable by manually grasping will rest upon shelfi? the knurled portions of the one or more or symbols 68 within the light-Way area.

In said device shown in Fig. 2', the symbols 63 are given movements of 90 degrees successively, by the, means illustrated in Fig. 5 and hereinbefore explained; the successive movements of any symbol being attained through the engagement of its single operating-handle in the proper holes 66 of each U-shaped arm of spider 51 engaged thereby successively. In the alternative device, shown in Fig. 6, the same result is obtained with reference to the movement of a symbol 63, but here through the engagement of its four operating-handles engaging successively the proper hole 66 in the single U- shaped arm of spider 51. Other-alternative devices for attaining this result could easily be provided within the scope of this invention.

Another possible feature of this device for showing the aforesaid base-to-base factors is shownat 66 in Fig. 6. This is merely an extra bank of holes 66, for halting a symbol in a slightlydifferent position with reference to any base-point than is afforded by the bank of holes 66; the purpose whereof being, for instance, to indi- (ate in one position that such a factor is safe or out and in the other position the reverse thereof. This extra bank of holes 66, were the device shown in Fig. 2 utilized, could just as easily be applied to that structure;'there being in this case four extra banks of holes 66, for each bank of holes 66 on each U-shaped arm of spider 51 would receive its concomitant bank of holes will be seen that the entire device illustrated in Figs. 2, 8, 4 and 5 is supported by plate I 13 of the stereopticon, due to the accommodation within pocket 23 of said integral machine of the said plate 13. In order to adapt said stereopticon for the use of ordinary slides, set screw 15 is loosened, slide 14 is slid to the right on rod 5, the said integral machine is lifted out, and set-screw 15 and sleeve 14 are then readjusted. on rod 5- in order to bring plates 1 0 a n d 13 close enou h together to properly accommodate the or inary slide-holder. tiflsttter when inserted f plate 10, and the dint'o fixed place by iii means of the thumb-screw 72, and the setscrew 73 in cap 74, which latter will then be placed n position. Screws 72 and 73 and cap are shown in dotted lines, for they are auxiliary parts which do not constitute a part of the complete stereopticonwhen the integral machine above-mentioned is a part thereof.

With the stereopticon equlpped with the integral machine as above described, the operation thereof should be obvious. The movement of the ball factor is shown with ease, as hereinbefore explained, by

means of the index 31, governed by the handle 33. The -base-to-base factors are also within easy control. The insertion or withdrawal of the indicators. 44: is easily attained, as clearly shown in Fig. 3 and Fig.

1. These indicators 44 may be used for divers purposes, to indicate the man at. bat or the score by innings or other features. An additional signaling device is the tinted lens 69, which may be operated to at will cast a tint over the image on the screen.-

Other additional signaling devices might readilybe utilized.

Inasmuchas many changes could be made in the above construction, and inasmuch as many apparently widely different embodisdments of my invention could be made withsi a e,

' guage used in' out. departing from the scope thereof, it is scribed and all statements of the-scope of the invention which, as a matter. of lanmight be said to fall th'erebetween.
