HORACE L. FREEMAN, OF NEWARK, NEW JERSEY.

ADVERTISING PROJECTION APPARATUS.

Specification of Letters Patent.

Patented Apr. 16, 1918.

Application led April 26, 1917. Serial No. 164,653.

To all whom t may concern:

Be it known that I, HORACE L. FREEMAN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented a new and useful Advertising Projection Apparatus, ofV

time to time and be at all times properly related in subject-matter to the advertisements shown by the first-named projecting means.

The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming partV of this specification, with the further under-l standing that while the drawings show a practical form of the invention, the latter is not confined to any strict'conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications come within the scope of the appended claims.

ln the drawings Figure 1 is an upright section through the projecting machine with some parts out back of the section.

Fig. 2 is a section on the line 2-2 of Fig. 1, with certain parts omitted.

Fig. 3 is a section on the line 3-3 of Fig. 2 omitting some distant parts.

Fig. 4 is a section on the line 4 4 of Fig. 3 omitting some distant parts.

Fig. 5 is a more or less schematic view of a screen showing the relative location of the images produced by the projection apparatus.

Referring to the drawings there is shown a base 1 on which are erected

pedestals

2, 3, respectively, carrying a shaft 4 attheir up-1v per ends, which shaft is substantially hori. zontal in the installed position of themachine.

Mounted on the shaft 4 yis a hub 5 with spokes 6 radiating to a rim 7 of appropriate diameter. Projecting from one side of the rlm are longitudinally grooved studs 8 arranged in circular series and having grooves 9 so disposed that transparencies or slides 10 may be mounted between adjacent studs 8. A convenient means of securing the studs in the rim 7 is by screw-threading one end of each stud, as indicated at 11, and

screwing it into an appropriate part of the rim. Each stud at the end remote from the rim is provided with a cap or clip 12 whereby the slides 10 may be heldI between the studs from accidental escape therefrom, and which on the removal of the caps may in turn be removed and replaced by other slides. Y

Projecting from one of the standards, say, .the standard 2, is an arm 13 on which is erected a post 14 carrying a .condenser 15 l in which it may be assumed suitable condensing lenses are mounted. Since the ap paratus in this respect follows the usual custom in projection instruments, it is deemed unnecessary to show the condenser lenses, although a face view of one con- Y denser lens 16 appears in Fig. 2.

Mounted on the arm 13 1s an adjustable support for an electric lamp 17 which may be of the incandescent` gas filled type of electric lamps.

Inclosing the wheel made up of the hub 5,Y spokes 6 and rim 7, and other parts off the apparatus, is a casing 18 having an opening 19 therethrough in front of which there is mounted a projection lens 2O of suitable type, the lens being carried by a,

bracket device 21 on the casing and provided with a support 22 rising from the bracket 21, so as to hold the lens 20 in proper positiom The arrangement is such that whenever the slide 10 is brought into line with the lamp 17, condensers 16 andlens 20, with the parts properly adjusted and focused, an image of whatis contained on the lantern slide is projected upon a suitable screen.

represented on a very smallscale at 23 in Fig.l 5. V The lantern slides are smarranged.

" the Worm 28 imparts a slow progressive that the image, simply indicated at in F ig. 5 Without detail, is displayed on the screen, and this image is so arranged as to leave a blank portion-25 thereon, say, in the.

middle. The image 24 may be that of printed matter, or pictorial matter, or'yvhatever rising from' the base 1. The gear'wheel 31 is carried by a shaft 33' also carrying a cam 34,1the drive means and gearing being propf erly'proportioned to imparta kslow rotative movement Yto the cam 34; l

Carriedby a support 35 is one end Aof'a rock arm 36, the other end of Which is provided With a longitudinal slot 37 traversed byy a pivot pin 38 'near one end ot a `lever 39'* constituting a latch lever.

Y

TWith the arrangement described,the slides 10 are-adjustedMai-id foc-useduponthe screen 23," and each slide is so kmade l that there isa blanlzfspace 'inits center portion corresponding to the space 25 inligxi capability of 'adjustment of the farm "49-'the optical axis of the projection app aratusfcon` sistingfotthe llamp 53, condenser system; 54,- slidecarrierv 8-`and projection lens 56,1may

Now, While the-ladvertisingQv-matter of the slides 10 is being displayedfthe object.

While the=invention is not limitedfto any one special object to--bey advertised, it is especially*- adaptedfvlfor 4.a 1verti'singf automobile-Wheels and the like, which may be shown?4 1n motionso far as the representationonftlieL screenlfis 'conce-medi? By means-lolfthe apparatusdescribed" e changinglslides mayeentainztext -fclescrirptise- Because ofthe of characteristics and advantages of some make of automobile wheel or tlre, and-while the changing slides are appearing on thev screen the wheel is shown in motion in the midst of the advertising matter, so that the observer by being interested in watching the rotating wheel is at the same time constrained to notice the advertising matter.

When it is desired to change the advertisement it is a simple matter to replace the slides l() by other slides and to replace the slide 6l by the representation of some other make of automobile wheel or tire, or the like.

In order that the display may be attractive all imperfections in the display should be avoided. It is necessary that the advertising matter and the moving part of the display should be sharply deined, especially as an indistinct display is very trying to the eyes. For this purpose two complete projection apparatus are employed, one for the projection or" the slides containing the advertising matter, and the other for the projection of the slide to which rotary motion is imparted. This permits both displays to be accurately combined on the screen and at the same time" to be accurately focused, thus avoiding any indistinctness of either display and obtaining sharp and clear cut pictures on the screen.

What is claimed is 1. An optical projection apparatus for advertising and other purposes, comprising an optical projection unit including light-giving means, condensing means and projection means in association, means for automatically presenting projection slides at prede-V termined intervals into the optical axis of the optical unit, and another optical unit including light-giving means, condensing means and projecting means with a support adjustable for causing coincidence of the optical axes of both projection units upon the screen, means for permitting rotating a lantern slide in the optical axis of the second optical unit, and means common to both optical units for driving the slide presenting means of the first optical unit and rotating the slide of the second optical unit simultaneously.

2. An optical projection apparatus for advertising and other purposes comprising two associated projection apparatus, each including light-giving means and a ,projection lens individual thereto, with one pro 7 jection apparatus adjustable with relation to the other to cause coincidence of their optical axes upon a screen, a rotatable carrier for a plurality of lantern .slides for moving the slides one at a time into the optical axis of one of the projectionA apparatus, a rotatable carrier for la lantern slide located in the optical axis of the other pron jection apparatus, and means common to both apparatus forV driving the first-named carrier to present the plurality of lantern slides one at a time in the optical axis ot' the corresponding projection apparatusy and for continuously rotating a lantern slide in the carrier of the second-named projection apparatus.

3. An optical' projection apparatus for advertising and other purposes, comprising two distinct associated projection apparatus, a rotatable carrier for a circular series of lantern slides movable to carry the slides through the optical axis of one of the projection apparatus, means for imparting a stepby step progressive movement to the carrier with the steps corresponding to the spacing of the lantern slides in the carrier, a rotatable carrier concentric with the optical axis of the second projection apparatus, and a common driving means for the two carriers and having connections with the second carrier to cause a continuous rotation of the latter.

4. A n optical projection apparatus for advertising and other purposes, comprising two distinct associated projection apparatus, a rotatable carrierffor a circular series oi? lantern slides movable to carry the slides through the optical axis of one of the projection apparatus, means for imparting a step by step progressive movement to the carrier with the 'steps corresponding to the spacing of the lantern slides in the carrier, a rotatable carrierconcentric with the optical axis of the second projection apparatus, and a common driving means for the two carriers and having connections with the second carrier to cause a continuous rotation of the latter, said connections being timed with relation to the second carrier to impart a high speed of rotation thereto as compared with the movements of the first carrier.

v 5. An optical projection apparatus for advertising and other purposes, comprising a suitable casing, a rotatable carrier therein with peripherally located means for supporting a circular series of lantern slides, a projection apparatus in part in the casing and located for the movement of the slides in the carrier through the optical axis oi said projection apparatus, another projection apparatus in part in the casingand provided with a rotatable carrier for a single lantern slide and concentric with the optical axis of the second-named projection apparatus, said second-named projection apparatus having a support adjustable with relation to the irst-named apparatus for causing coincidence of the optical axes of both apparatus upon a screen, and driving means common to the slide carriers of both projection apparatus for impart-ing a step hy step movement to the tiret carrier, and i a,.fconti11u0us rotative movement. to: thefsec-4 21S; :my own,I.lume:hereto aXQdmy-:Sgnaf ond .Camiel-1,' with .thel rater-of: movement lof i ture -11.the`pr.esenceiof:tWoWt-nesses; thetwo Qarrersltijmedio iVm-pmiJ 'torthesecf.V HRACEL; lFREEMMNl ondrczutrlerfa; lnghspeed of imovementgasl 5 compared to-;=theVV ratei. -of movementofv :the v Witnesses: 1
