If desired a light boundary need not be projected upon the material to .a housing containing a suitable light source 18 and be provided with a projection lens systern 19. In order to more effectively utilize the light from the source18 a condenser lens system 20 may be positioned within the housing 1 of the projector. At a suitable point intermediate the condenser and projection lens system there may be positioned a light grating which, as more clearly shown in Fig. 3, may comprise a frame 21 carrying two sets of guides 22 and 28 at opposed ends of the frame 21. The frame 21 may be of channel iron or angleiron. The guides 22 and 23 may be tubular members suitably connected to the frame 21. The frame 21 may also in clude cross members 24. The projector 1 may be preferably provided with a suitable opening, such as the flanged opening 25, adapted to receive the frame 21 and guides carried thereby.
Springs or other suitable locking members 26 may be carried by the projector so as to retain the frame 21 within the projector.-
The frame 21 may be provided with stops 27 at one end thereof. said stops being adapted to cooperate with the ends of the flanges 25 so as to position the frame 21 within the pro ectOr.
(lne of the simplest embodiments of the invention comprises U shaped carrier members 28 and 29, the free ends of said U shaped members extending into the guide members 22 and 23. By having the ide members 22 and 23 inthe same plane rel aitive to the plane of the projection and condenser lens of the projector, the ends of the carrier members 28 and 29 are also in the same plane. Delineating members'may be carried by the free ends of the carrier members 28. and 29. il or example, the ends 30 and 31 of the carrier members 28 and 29 extending into the frame 21 may be provided with means for holding delineating members such as the wires 32 and 38, respectively. Instead of wires, ribbons or even solid members provided with slots may be used as delineating members.
Various means for attaching the delineating members to the carriers may be employed. One of the simplest means, when \wires are used as delineating members, may comprise notches 34- cut in the ends of the carrier members and inclined notches or slots 35 cut in the sides of the carrier members 28 and 29and their ends. The Wires 32 may be passed through the slot 34 and then tightened into For example, as shown in Fig. 3, such locking means may comprise set screws 36 passing through threaded apertures in the guide members 22 and 23 and bearing against the carrier members 28 and 29 positioned in said guide members.
In order to provide access to the ends 30 and 31 of the carrier members 28 and 29 and to the locking means, such as the set screws 36', the frame 21 may be provided with a removable cover, such as, for example, the cover member 37, illustrated in Fig. 7. As shown in Fig. 7, the frame 21 is substantially in the form of an angle iron. Near one end of the frame 21 there may be a lug 38 extending over the guide members 22 and 23 and slightly spaced therefrom. A cover member 37 may be exteriorly connected to the lug 38 as by means ample, extension members 40 and 41 may be I provided, said extension members being connected by suitable means to the carrier members 28 and 29,. respectively.
The extensions 40 and 41 are preferably in V a plane parallel to the planein which the can rier members 28 and 29 may be moved. The extensions 40 and 41 may be provided with alined slots or apertures 42 and d3, respectively, each of said slots being provided along one inner edge with rack gears 44. An adjustment means may be provided, such as, for example, a knurled knob 45 mounted upon a pin 46 which extends through the longitudinal openings 42 and 43. A small spur gear ll rigidly connected to a secondary spur gear 5 adapted to engage with the reel: gear made one side the slot l3 of 'lhe spur gear 4:? is similarly in operative corn or with the raclr formed in one side the slot 42 extension member sit.
loosening the loci: c rid nianu rotating the knurled knob while r sin .2 ing knob i9 irom rotation, the rotat y motion may be imparted to the spur gear at? thereby translated into a l movement of the extension &9 which turn longitudinal motion to the c 1' 28 relative to carrier mem- 's stationary, rly tion of the knurled knob 29 ll parts a similar motion to the spur gear 59 Willfili imparts a longitudinal motion to the extension and the carrier 29. In this manner the two carrier members 28 and 29 may be moved accurately relatively to each other and loclred in a desired position thereafter.
A modified form of light grating is shown in Figs. 9 and 10. Tubular guide members 22 and 23 are employed in this modification and cylindrical carrier members 28 and 29 are also employed. The modifications shown in the drawings facilitate the insertion ofthc carriers with delineating members attached and in that way obviates the somewhat awkward process of connecting the delineating members to the carriers while said carriers are within the guides and within the frame. These objects may be accomplished by the following construction:
The guide member 23 may be rigidly connected to the frame 21 by any suitable means, for example, by welding. A slot, or opening, 51 may extend longitudinally down the guide 23, the slot or opening 51 being substantially in the same plane as that assumed by the delineating members 52 carried by the carriers 28, 29. The adjoining guide 22 may rest freely upon the bottom portion of the irame 21 and be rip-idly connected to spacing men1- ber 53 adapted to be positioned immediately above the cross piece 24 connected to frame member 21. Means for connecting spacing member 53 and the cross may be provided, such means conipr' example, a machine screw A be connected to the frame 21 or to guide 23 and extend over the guide 22 so as to maintain the guide member 22 in operative position.
rotary mo- By means of this construction the end light grating may be disassembled by removing the machine screw 54 and then pulling the carrier member 28 together with its guide 22 and the spacing member 53 out oil the frame 21.
llt is not necessary to remove the deineating member carried by the carrier 28 in order to remove the carrier member from N tle rramc 2i lhe delineating member car l-us ed by the carrier 28 may be adjusted exy of the frame 21. Aiterithe carrier Q has been removed, as described hereinaboye, then the carrier 29 togetherwith its delineating member 52 may be removed from f ame 21 by merely moving the carrier 29 dinslly out of the frame 21, the delineating member 52 passing through the slot- 51 of the stationary guide 23. By reversing the operations described hereinabove, namely, by inserting the carrier 29 into the frame 2i and then inserting the carrier 28 and its guide 22 the "frame, the appa-.
ratus may be assembled.
in order to prevent the delineating memers carried. by the carriers 28 and 29 from coming into forcible contact with one another, stops 56 and 57 may be carried by the carriers 28 and 29, respectively, exteriorly oi the i ranie 21. The stops 56 and 57 may be machine screws inserted into the carriers 28 and 29 in such position as to come into abutting relation whenever the delineating inern bers carried by the carriers 28 and 29 come into. substantial contact.
in Fig. 12 is shown a diagrammatic representation of a projector adapted to be carried in projecting light boundaries in accordance with this invention. This projector may consist of a housing containing a light source 18, a condenser lens system 19 and a projection lens system 20. The frame carryin the delineati'ng members is shown at 21. mirror 58 may be exteriorly supported as at 60 in front of the projection lens system 20 upon outwardly extending arms 59 projecting from the projector housing. The arms 59 may also carry a slotted sextant 61 cooperating with a pin and lock nut carried by the mirror 58 whereby the mirror 58 may be positioned at any desired angle to the plane of the projector lenses 20.
