l5, the wall 17 beinghinged at one edge 18 i so as to permit of outward swinging of the opposite edge thereof'in order to gain access to the compartment A. The wall 17 is locked in operative position by means of latches 19 and 20 slidably mounted upon Fig. 10. lA helical compression spring 21'4 coperates with the member 19 for normally holding the same in operative position, the other latch being held in operative position by gravity. Exteriorly positioned knobs 22 cooperate with latches 19 and 20 for manually moving the same to unlocking position.

One of the lateral -walls 23 of the housing, as clearly shown in Fig. 5, is rigidly secured to the frame 15, the other lateral wall 24 being hingedly connected with the rear wall 25 of the housing at 26, said rear wall being in turn hingedly connected at 27 with thepiear edge ofwall 23, the arrangement being such as to permit of the walls 24 and 25 being swung around and folded together, as shown in dottedlines in Fig. 5,

so as to permit of ready access to the interior of the device. The wall 24 is locked in operative position by means of latches 28 which are slidably mounted upon the inner side of said` wall adjacent the front edge thereof, as clearly shown in Fig. 10-,said latches being adapted for engagement with sockets provided for coperation therewith in the frame 15. Said latches 28 are controlled by a key which may be inserted through ap exteriorly opening key hole 29,

.as will be readily understood. The free edge of the front wall 1-7 which is bent back to forin the end wall of compartment A is'pi'ovided with arearwardly projecting flange 30 which isadapted to overlap with the front edge ofwall 24, thus making it necessary to first unlock the wall 17 before tlie wail 24 may be swung outwardly. .Cooperating with the rear wall 25 are also slidably mounted latches 31 vand 32 arranged upon the inner side thereof, as clearly shown .in Fig. 11, said latches being adapted for engagement with sockets `provided for cooperation therewith in frame 15 in the same manner as latches 19 20 and 28. A helical compression spring 33 coperatcs with the latch 31 for normally holding the saine in Alo opens into the rearward end of a projecting tube 36 which projects forwardly from said wall, being provided at its front end with the usual lenses mounted in an adjustably mounted holder 36. Formed in the wall 16 is la, coaxial circular opening 37 behind which are mounted the conventional condensing lenses carried in a holder 38 mounted upon the inner side of wall 16, as clearly. shown in Fig. 1. Arranged directly behind the lense holder 38 is an arc lam 39 with the upper end of which communicate electric conductor wires 40.'.1 The lamp 3') is suspended from a substantially inverted U- shaped vertically adjustable support 41, said supportbeing held in positions of vertical adjustment yby means 0f thumb screws 42 which are threaded upon studs 43 projecting inwardly from Ydepending arms 45. The ends or sides of member 41 are provided with elongated slots 46 to afford clearance for the studs 43, as clearly shown in Fig. 4. The upper ends of arms 45 slidably engage -with supporting bars 47' formed integral "with frame 15, the arrangement being such as to permit of adjustment of the are lamp toward and from the condensing lenses. Set

screws 48 coperate with the members 45 for locking the samein positions of adjustment.

" With this arrangement then it will be seen that, through the vertical adjustment afforded the supponting element 41 and through the horizonta adjustment afforded the supporting arms 5, the lamp may be adjusted vertically and horizontally in order to properly position the same relative with which the same copera The upper wall of the housing of the device is cut away as at 49 to afford clearance for the upper end ofthe lamp and the su port therefor, a supplemental housing .59 heilig arranged upon the upper end of the main housing for inclosing said end of the lamp and the support therefor. The supplemental housing 50 is secured in position by means of nuts 51 which engage with studs 52 projecting upwardly from frame 15, as clearly shown in Figs. 4 and 9.

Arranged in the compartment A is a cir` cular slide-holder 53 which is mounted upon the front end f a shaft 54 rotatably mounted in suitableydearings securedto supporting bars 55 and 56formed integral with the frame 15, at the front and rear sides thereof,*as clearly shown in they several views. 'lheslide-holder is 'formed' adjacent its pei rlphery with a plurality of equally spaced rectangular openings ,57, ove'.` which. the

slides 58, which it is desired to project, are

adapted to be arranged. The slides 58 are Fig. 3, are adapted to engage with the innerl ends of slides 58 to limit inward movement thereof. The slide-holder 53 is so mounted that, in the rotation thereof, the slides 58 will be successively brought into registration with the projecting lenses in order to effect the projection of the pictures or matter upon said slides through the projecting tube 36. 'A

Rotation of the shaft 54 is controlled by a pair of ratchet wheels 461 and 62 secured to the front ,and rear ends respectively of .said shaft. Coperating with the ratchet 61, as clearly shown in Figs. 6 and 7, is a pawl 63 which is pivoted at 64 to the supportingA bar I55. 'A helical tension spring 65 coperates with the pawl 63- to normally hold the same in operative relation with4 the ratchet'wheel 61 'in order to prevent positiveorforward rotation of the shaft 54, it being necessary, therefore, with this arrangement in releasing the shaft 54 so `as to permit ofpositive rotation thereof, to rst rock the vpawl 63 to inoperative position. For V.this purpose the pawl 63 is formed withv a substantiallyI horizontally disposed extension 66 which is adapted for engagement bymechanism hereinafter described in effecting releasing movement of `pawl 63. Coperating' with the ratchet wheel 62, as clearly shown -in Figs. 4 and 7, isa pawl 67 hinged `at 68-to a supportingarm. 69 projecting upwardly to the lenses i f rom supportingbar 56.l A helical tension spring 70 coperates with the pawl 67 to normally hold the` same in operative relation with said ratchet wheel 62 in order to prevent retrograde rotation of the shaft 54.

Arranged below the shaft 54 is a shaft 71 rotatably mounted in suitable bearingssecured to frame bars 72 and 73 formed integral -with frame 15. Fixed to the'shaft 71 is a gear 74 with which meshes a pinion 75 fixed to a shaft 76 which is mounted in suitable bearings also secured to supporting bars 72 and 73. The shaft 76 also carries a worm wheel 77 which meshes with a worm 78, as clearly shown in Fig.v 4, provided upon the power shaft 79 of an electric motor 8 said motor and power shaft being s itably mounted upon bearings arising front the bottom of the housing of the machine. .,Conductor wires `81 are shown for coperation with the motor 80, said wires together with'` the conductor wires 40\ which coperate with the lamp 39, bemg united for connection with 'a sourceof electrical energy. -With this arrangement it Will be seen that upon operation of the motor the gear 7a will Vbe rotated. i

Formed in one side of the gear '74, as clearly shown in Fig. 8, is an annular chan- Iiel 82 in'the bottom of which is formed an annular' slot 83, the inner and outer parts of the gear which are thus completely severed from each other` being connected by straps S4. Mounted for sliding adjustment in the slot v1831s a plurality of tappet members 85 wir i are adjustably fastened to the gear 7J( by-ineans of 'screws 86 and cooperating nuts 87. The inner ends of the tappets 85 are square in order to prevent relative rotation of the same in the slot 83. The outer end 85 of each tappet is angularly formed for engagement with the e\tension4 G6 of the pawl 63, as clearly shown in Fig. 7,-so that` in the rotation of gear 74, the pawl G3" will be successively moved to inoperative position by y reason of the successive engagement of the ends 88 of the tappets with said extension 66.

Mounted upon the shaft fill, adjacent the l ratchet 61, is a gear or sproeketwheel 8'.)

which is positioned eoplanar with the inner 'or base portions of the tappets 85, as clearly shown in Fig. 8. The arrangement is such that, in the rotation of the gear 74, the base portions of the tappets 85 will successively engage with the"teeth of member 89 in order.

to effect intermittent rotation thereof and hence of the slide-holder carried -by the shaft 54, The extension 6G of the pawl (33 is so positioned relative to the member Si), that said pawl will be moved to releasingl position vby each tappet extension 88 before the tappet proper engages with said member 89. Also, the parts are soproportioned that carry oneslide from projecting position and to carryfthe succeeding slide'vin projecting position. Thus, the successive engagen'ient of the tappets with the member 8S) will serve to intermittently move the slide-holder to successively position the slides carried thereby for projection from the machine. Upon the vjjmssage of a tappct from engagement xiviththe member 8f) and the extension ($6 of theI pawl (38, the latter will immediately moveto operatij-'e position under the in- .;fiuence of spring (35 so as to preventexcess y'movement of the slide-holder through inyei'ti'a. By spacing the tappets along the slot-83, it is, of course, apjiarent that the `duration of exposure of the slides projected un the machine may be governed de- -ed and any nuinber of tappets may be employed, vdepending' upon the length of time it is desired to expose each slide.

Through the hinged mounting of the front ifall 17, access may be readily gained lturbing any other part of the mechanism.

Access to the interior of the machine for adjustment of the tappets, or for any other purpose, may' be readily and easily gained by unlocking of the walls 24 and 25 and swinging of the same to the dotted line position showniin Fig; 5.

With the construction set forth then` it will be seen, that a machine is provided which, in operation, is entirely automatic, the slides carried by the slide-holder upon which advertising or other matter may be ai' langed. being successively projected from the machine onto the screen which is used in connection with thenulchine.
