Application filed November 10, 1909. Serial No. 527,157
To all whom it 'mdg concern:
Be it known that we Ronnn'r Funcom, FREDERICK S. M URRAY, and m/ran Mumm r, citizens of the United States, and residents of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in An'iusement Apparatus, of which the following is a specification. 1
This invention relates to an amusement apparatus designed to reflect upon a screen the image of a subject and particularly the image of a living subject. I
The apparatus also provides for causing the reflected image to move on the screen, such movementanswering to a certain move ment, but dissimilar movement, of a subject.
The invention consists in the apparatus and features shown in the drawings and as hereinafter described and claimed.
In the accompanying drawings forming part of this specification, and in which like reference numeralsdesignate correspoluling parts in the several fig!lres,--- -Figure l is a plan view partly broken away and partly 171806111011; Fig. 2 is a sectional elevation on the line 2-2 of Fig. 1 Fig. 3 is a rear elevation looking toward the left of Fig. 1; Fig. 4 is a sectional plan view on the line 4l-flof Fi 3; Fi 5 .is a sectional elevation on the line 5 5 of Fig. 1; and Fig. (5 is a diagram of the electrical circuits and connections.
Referrring now more particularly to the apparatus as shown in the drawings, 1 is a cabinet designed to rotate or turn about a fixed center having an opening 2 in its lower side and a curtain 3 hanging down from the cabinet and a part of which closes the front end of the cabinet.
4; is a pivot block secured to the lower side of the cabinet and having a conical recess to receive the conical end of the tubular pedestal 5 whose lower end is fixed to a base (3.. The block iforms the upper end of a tubular sleeve 7 surrounding the pedestal 5 and provided at its lower end with a spacing I ring 8.
' f} is a support for the seat 10 on which the subject may sit whose image is to be thrown upon the screen. The support if surroln'lds the sleeve 7 and is supported in place by a hinged connection 1? with the lower side thereof. This reflector is so mounted as to be oblique to the axis of its ibi n rotation and that of the cabinet. The reflector fits in between the two wings H and 15 at the rear of the. cabinet. its obliquity may be adjusted on the hinge l t by a set screw it) carried by the. reflector and adapted to en gage the wing 14 so as to hold the reflector in position.
17 is an are-shaped extension from the reflectors fran'ie whose purpose is to prevent the escape from'thc cabinet of light. above. the reflector when the latter is tilted back from its positi'nxas shown in Fig.
The reflector 12 maybe called the primary reflector; L
18 is another hinged, reflector which may be called the secondary reflector. It is maintained in coiip'erative relation with the primary reflector so as to receive from the reflector 12 the reflected image and throw it upon the screen. The reflector 18 is mountedinthe axis of rotation of the reflector 12 and of the cabinet 1 and is oblique to this axis. it forms the upper end ol. the sleeve 19 which is provided with an opening 20 through which the light rays from the reflector 18 pass forward to the screen. The sleeve 19 is loosely mounted on the tube 21 which is provided with lenses 22 and 23.
24 is a gear wheel fixed to the sleeve 1.) for a purpose hereinafter described.
25 is :2. pi; on wherebythe two sections of the tube 21 may he moved for the adjust;-
ment of the lenses 22 and 2 1.
26 and 27 are two lamp chambers located on opposite sides of the reflector 1.2. 'lhey are carried by the cabinet and open thereinto in advance of said reflector. ilach provided with an arc-lamp 28 and each is provided with a. lens 29 and a Water screen 230 through which the light rays pass before entering the cabinet. The water screen consists of a chamber containing water and flit) havingits front and rear walls made of translucent material, such as glass. The water screen serves to absorb the heat rays i from the lamp. The lenses serve to converge the light rays upon the subject occupying a position in the cabinet in front of the reflector 12. The subject may sit upon the seat with the head thrust inside the cabinet through the opening 2.
Any suitable means may be employed for rotating the reflector 12 and cabinet and for holding the reflector 18 against rotation. As shown in the drawings a motor 31 is employed for rotating the cabinet and reflector.' Its shaft carries a pinion 32 which meshes with a gear wheel 33 fixed on the pedestal 5. Meshing with the gear wheel 33 is a pinion 34 carried on the shaft 35 which turns in bearings in the support 9 and in the bottom of the cabinet 1. The upper end of the shaft carries a pinion 36 which meshes with the gear -wheel 24. WVhen the motor operates the pinion 32 travels around the gear wheel 33'causing the support 9, sleeve 7 and cabinet to also turn about the edestal 5. This movement causes the sha t 35 t0.
travel around the pedestal with the support .9 and cabinet and imparts a rotary movement to the shaft through the gear wheel 33 and pinion 34. As the shaft 35 rotates, its

When the subject is, for example, a woman,
seated on the seat 10, her head will extend.' into the cabinet As she .sits opposite the,
The lamps 28 are employed to illuminate the subject whose image is to be reflected. It is preferred to employ arc-lamps for this purpose and the a paratus is rovided with circuits for the iamps inclu ing switches and resistances carried by the'support For this purpose circuit wires pass. into the tubular pedestal 5 from the source of'current and are connected, respectively, to insulated contact rings 37 and 38 carried on the outside of pedestal 5.
39 and 40 are contact brushes secured on the outside of the sleeve 7 I and passing through aperturesin the sleeveinto contact with the rim s' 37 and 38. The contact brushes 39 an 40 are connected by wires 11 and 42 with plug socket 43. These brushes are also connected by wires 44 and 4.5 with plug socket 46. 47 and 48 are plugs for the sockets 43 and -46 and are respectively connected with the lamps in the lamp chambers 26 and 27 through resistances 49 and 50. When these plugs are inserted in their sockets, the lamps are in circuit through the resistances which are in series with lamps.
51 and 52 are additional plugs connected 1 with resistances 53 and 5 for the plug 51 is connected with resistance 49. When the plugs a7 and 5,1 are in their sockets, the resistances L9 and 53 are in multiple with their connected lamp 28. I
The socket 55 7'5 56 is a socket for the plug 52 and con- 30 nected with resistance 50 whereby the resistances 54 and 50 may be connected in multiple with their lamp 28.
57 and 58 are standards carried by the support 9 for supporting the resistances and 86 the plug sockets.
The top and side walls of the cabinet 1 are formed of a series of separated overlapping plates arranged to form tortuous passages between adjoining plates so that the 90 passage of light rays through the'wall may be obstructed particularly the light rays projectcd into the cabinet by the lamps-28, the
passage of sound waves being permitted through these tortuous passages between the plates. In this way the light thrown upon the subject within the cabinet is intensified and the ,voice ofthczsubject, either in sing ing or speaking, may be readily heard out--v side the cabinet without serious diminution.
59 indicates the plates forming the top Wall of the cabinet. These plates are arranged parallel to each other and arefastened together by the rods 60. The side walls of the cabinet are formed by similar plates 61 similarly arranged and are fas tended to ether by the r0 s 62. 1
It will e noted that the plates of the several walls slant in the same general direction," their inner edges-pointing toward the rear of the cabinet and away from the lamp chambers 26 and 27 which 0 en into the I cabinet at the front side thereo What is claimed and what is desired to be secured by Letters Patent is i 1.
