hooks will be caught by the projections 29 and the carrier will then slide down the upper runway towards the lower extremity thereof.

At the lower extremity of the runway l1 isan escapement permitting one at a. time from the number of carriers which may be collected at the front extremity of the runway 11, as illustrated, to be dropped behind a projecting lens 80 and between it and a condenser 31 behind which is an incandescent electric lamp 32 carried in a holderthe position of which can be adjusted along a rod fixed to .the case 10. e

rlihe esca-pement ycomprises two rocking spindles 33 and 3/1 which are rocked by the link-connections 35,' 36, 37 and 38 from a rocking lever 39 rocking' about a. pin 40. 'E he end of the rocking` leuter 39 is adapted to be en gaged once in every revolution of the wormwheel by means of a laterally-projecting' pin l1 in the path of which the end et the lever 39 is disposed. y

llifhen'the rocking lever 39 is in its normal position (shown in chain-lines in Figure@ the rocking` spindles and their operating links are .in 4the positions illustrated in Figure 1. lnv this condition jaw-like membersy 42,v which comprise the main escapement -members, one at each end of the shaftl 3S,

present their jaws vertically downwards so as to hold baclr the carriers on the runway 11, and hooks 43 on the spindle 34 are inserted through orices in an apertured plate -l-fi between the lens and condenser 31. When the rocking lever 3i) is moved to the full-line position shown in Figure 2 by engagement with the pin d1, the links 35, 36 and 37 are moved to the dotted line positions shown in Figure 2 and 'the members 42 and 413 are in the full-line positions. position, ythe members 4t2 are ready to receive the hooks of the adjacent carrier. When the pin L11 disengages 'from the end or' the rock lig-lever 39 springs 45 surrounding A the spinillelB-lf return the parts te the position illustrated in `Figure 1 which releasesv thesnd carrier 14 so that it slides beyond and drops from the extremities of the run- \vay-men1bers 1l.. Before it thus drops the hooks @iii have been re-inserted to extend be yond the back of the plat-e let andI catch in the hooks 13 of the carrier which has thus dropped and suspend it. so' that a picture held in the carrier is exposed at the orilice lo in the plate lli. At the next, engagement ot'v the piu -l1 that carrier .will be dropped on to the lower runway 12 its Dtall being checked by leatsprings l1ZL as indica-ted in Figure 2, when the hooks 48 are withdrawn lore the next succeeding carrier is dropped on to theifhoolis aftter they are moved back again into the dotted-line position illustrated in i .Figure 2.

'iooperate in conjunction with such a deln this e v lessees vice an attachment may be provided coniprising a case, conveniently ot' bellows form, 50, having means to pass it over the lens 30 and a ground-glass or other translucent screen 51 on to which the pictures may be projectedu The electrical connections are as shown in Figure 4. A plug connector at has one pole connected to a'switch (31, conveniently carried outside the case 10, and the other pole connected in parallel with one terminal of the lamp 82 and oneterminal of ythe motor 28. 4rEhe other terminal of the motor is connected through a starting rheostat 62 with the other pole of the main. switch (il, whereas the other terminal of the lamp 32 is connected in series with a output or knifesw'itch 63 itself' in series with thel main switch 6l. As shown more clearly .in Figure 2'the leaves` of the knife-switch `63 are mounted on the standard or pillar 17 and the blade G4 ofthe switch is carried on the rocking lever 39. Thus, during the/chang-- ingf of a. picture the lightis cut dut.

ri`he invention is notlimited to the use of the. apparatus for the purposesof pictureprojection,although this is itsochiei application, but it may have a wider application in the transportation of loads from a low level to a higherl level from which they aire to pass to a distant point-.whereaifter the carriers liorvthe loads are returned to the starting or initial. position. l

Picture projection apparatus comprising convergent runways disposed one above the other, carriers adapted to contain pictures and provided with hooks to enable them to gravitate along said runways', rotary drivingr means, a pivoted arm adapted to be rocked by said driving` means, a spindle carried by said arm and provided with spring detents 'to lift the carriers, guides for said spindle, means tor transferring the carriers from said detente to the upper end of said upper runway, es'capementv mechanism to release the carriers successively from the upper runway, optical projection means, means to hold successive carriers stationary across the optical axis of said optical projection means subsequently to their release by the escapementmechanism, means whereby the source ot light for Athe optical projection means is operativo' only during' the time that a pir ture is in position `for projection. and means to subsequently release the rarriers successively and allow them to fall on to and slide v along the lower runway.
