Patented Nov. 4, 1952 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to a toy and has particular reference to a projector for throwing pictures upon a miniature screen.

An object of this invention is the particular construction, as will be set forth, of the casing of the projector to give access to the interior of same.

A further object of this invention is the provision, in the projector, for progressively moving a series of pictures arranged upon an endless lm and simultaneously closing an electric circuit to light a bulb to project each picture upon a screen as it moves into projection position.

A still further object of this invention is the provision of a. device in which the constituent elements are so arranged structurally and functionally as to assure improved results with materials and members which may be manufactured at reasonable cost, may be easily assembled and which will be efcient in operation with minimum wear to the parts.

The invention possesses other objects and features of advantage, some of which, with the foregoing will be set forth in the following description and in the claim wherein parts will be identiiied by specific names for convenience but they are intended to be as generic in their application to similar parts as the art will permit. In the accompanying drawings there has been illustrated the best embodiment of the invention known to me, but such embodiment is to be regarded as typical only of many possible embodiments, and the invention is not to be limited thereto.

The novel features considered characteristic of mv invention are set forth with particularity in the appended claim. The invention itself, however, both as to its organization and its method of operation, together with additional obiects and advantages thereof, will best be understood from the following description of a speciiic embodiment when read in connection with the accompanving drawings. in which:

Fig. 10 is an end view of same and shows part of the split casing or housing.

Fig. 11 is a section of a part of the housing taken approximately along line 2|-2l of Fig. 13, and

Fig. '12 is a detail showing a modification which will be hereinafter described.

Referring in detail to the parts, 60 designates a projector having legs 6| thereon and formed of two semi-housing units B2 and 63 which are held together by hinged vioints 64 and a lip meinber |D8 having tapered lip members |2| and |22, as will be hereinafter explained.

The leg formations upon the bottom of the semi-housings 69. and 63 comprise the strips 6| upon the semi-housing 62. each having a perforation which engage pins 68 formed unon strips 69 on the bottom of the semi-housing 63. Both strips are slightly fievible to enable them to be sprung apart for atta ehment or detachment. The semi-housing 63 is formed with a half cvlin'irical lens holder 1f! which is integrally formed thereon. The semi-housing 62 is formed with a lug 1I adapted 130 engage the outer edffe T2 0f the defenhable half wunder lens holder 73.

When the two half sections 62 and 12 of the housing are brought together along the line 74, the half cylinder 72 is slinned over the lug 1|, against the semi-@vlinder 'In and the both seroicylinders held together bv means of the split rings |25 and Sli. FiYed focus lens 75 and 7B are held within the said semi-cvlindrical members 'Hl and 73 to forro the lens holding cylinder El. Within the housing there are two batteries Tl and 'I8 connected in series by a connector 19 removably mounted unon slotted in=nlating members 89. The upper end of tbe batterv 'l1 oontacts a spring conducting element 8| which is removably mounted upon slotted insulating members 82. An electric light bulb 83 is carried upon a metallic mounting 84 in turn removably mounted upon slotted insulating members `85. One side of the said light bulb 83 has electrical contact with the said mounting 84 while its other side has electrical contact, through the Contact point 86, with the said spring conductor 8|. An electrical conductor 81 having an angular flexlic mounting 84 in close proximity to the flexible end 86 so that an open or circuit breaking gap is normally maintained at that point. An opening 92 in the housing of the projector 60 is alined with the said lenses F5 and 76 and removably mounted in the semi-housing 66, upon slotted mounting members 93 is a condenser lens 94 alsov alined with and disposed between the opening 92 and light bulb 83.,

An endless strip of film 95 carrying a multiplicity of equally spaced pictures 96 (shown by dot and dash line in Fig. 3V and in part in Fig. l) is mounted between guide pins 97 and the outer top, bottom and end walls of the semi-housings and is held in proper alinement by means of guide blocks 98 upon the semi-housing 63 and guide blocks 09 upon the semi-housing. 62. The said film strip 95" is perforated, at intervals between pictures, as at (Fig. 1) and. provides a means, for engagement with selector points'. lill formed upon a slider |02 movable upon the top of the projector 60 in an opening |03 in same. The said slider (Fig. 10) is formed with grooves |04 and |05 which engage over the edges of said opening |63. The groove |05 is formed with a lip |06 which engages over a ridge |01 formed along the edge of the opening |03 and acts, to hold the. said slider upon the semi-housing 63 when the semi-housing 62 is disconnected therefrom.. The, inactive position of the slider |02 is shown in Fig. 3 but when it is moved forward it engages the upper surface of the said flexible end B6, and depresses same to close the circuit between same and the, end 9| of theJVA metallic mounting 84. With the circuit closed the light bulb 93 isl illuminated and projects the picture, alined therewith,4 upon. the screen.

When the slider |02. is retracted to its, normal, inactive position, the circuit is broken and the light is extinguished. To project the following picture upon the screen,4 the slider |02 is again moved forward, whereupon the selector points IUI engage the corresponding perforations |90 and moves the lm 95 forward to. aline the following picture and close the said circuit. This operation may be continued until all of the pictures have been successively projected. Side guides |013 and, |05" are provided upon the semihousings 62 and 63 respectively and are adapted to assure, correctA alinement of the said. film perforations with the said selector points (Figs. 3 and l1).

On Fig. 12 there is shown a modified form of hinge comprising a flanged member i0 having a slotted or hookopening, which is adapted to engage over a pin 66" similar to the pin 68. heretofore mentioned.

A lip member |08 is formed by two sections. one upon each of the semi-housingsr 62 and 6,3 and functions as a means for snap locking the two said semi-housings 62 and 63 together. Each of the said' lip members are formed with a tapered lip member |2| upon the semi-housing 62 and a complementary-tapered lip; member 22 upon the said semi-.housing 6.3; (Figs. 2d: and 2e). The two said tapered lips. 12| and |22/ co-act with the lock hinges 64.

Figs. 2, 2b and 2c shgw a form of hinge wherein the aforesaid leg stripsl 6| are formed' with offsets |23 havingA a bearing perforation |21!v and slots |25 into and along which pins |26, formed upon the leg strips 69 are adapted to engage. The pins |26 being adapted to-snap into vthe perforations I claim: In a miniature toy projector, comprising a y housing formed of detachably joined half sections, lens upon the housing aligned with an orice in the housing, hinges and a snap lock upon the half sections of the housing, multiple pairs of slotted, insulating supporting members upon andinside of one of the half-sections of the said housing, a condenser lens removably mounted within the housing and aligned with the oriiice in said housing, a metallic light bulb carrying member removably mounted in a pair of said insulating supporting members and forming one terminal of. a normally open electric circuit, a light bulb engageable through the said metallic light bulb mounting and having electrical connection therewith and arranged in alignment with the said lens, orifice and condenser, a pair of dry batteries within the housing, an electrical conductor element engageable with the opposite poles o said ydry batteries and removably mounted in a second pair of the said slotted insulating supporting members, a spring conductor element removablymo-unted in another pair of slotted insulating supporting members, the said spring conductor having an. angularly projecting end engageable with one pole of onev of the said batteries and havingr electrical connection with the contact point. of the said light bulb, a conductor element mounted in a fourth pair of slotted insulating and supporting members, the said conductor element having contact, at` one end, with the opposite pole of a second dry battery and having its opposite end angularly bent and projected toward the upper end of the said metallicy light bulb member, but out of contact therewith to normally maintain an open electric circuit, an endless iilm having a. multiplicity of' spaced' pictures thereon engageable upon guide pins around the inner' periphery of the. said housing, the said pictures upon the endless lm adapted to consecutively andy intermittently align with the said orice,
