From the loiccoing description inkcn in connection With the accompanying drawings, it will be apparent that I have provided a simple, practical, and cheaply manufactured shadowgraph machine which may be operated so as to furnish amusement for many spectators..

It is to be understood that While I have shown and described the preferred embodiment of inyinvention, I do not Wish to be limited to this exact construction, combination, and arrangeinent of parts, but may make such changes as will fall within the spiritand scope of the invention as claimed.

Having thus described my invention, l claim r- 1. In .a machine of the character described, a support-ing structure, a skelet-on frame formed above the same, a pair of spools having trunnions formed upon their upper ends and sockets formed in their lower ends, said sockets being,` received Within openings formed in said frame, a pair of revoluble shafts journaled in the supporting structure, and extending into the sockets formed in said spools5 a web connected to the spools land adapted to be Wound from one t0 the other, said web being transparent vand formed with opaque portions, and means for rotating the spools.

2. In a machine of the character described, a table, shelves secured to the rear edge of the table top and disposed in a plane below the same, a frame Work supported above the table, a pair of spools having trunnionsI formed upon their upper ends, the frame Work being formed with openings to receiveI said trunnions, a pair of shafts having* their upper ends squared,

qceases the lower ends of the spools beingformed with sockets to receive said squared portions of the' shafts, the shafts being journaled vertically in openings formed in the shelves, a bevel gear rigidly secured to one of said shafts, a third shaft having a bevel gear secured thereto and meshing with said first mentioned gear, means for'rotating the last mentioned shaft, and a web secured. at its ends to said spools.

s. ln a machine of the character described, a. table having a top disposed in a horizontal plane, shelves secured to the rear edge of said top and disposed in a plane below the saine, a traine Work supported above the table, a pair of vertical spools having trunnions formed upon their upper ends and squared sections in their lower ends, a :traine Work being formed With openings to receive said trunnicns, a pair of vertical shafts journaled Within openings formed Within said shelves, the shafts being formed with squared upper ends for receptionwithin said sockets, means for re-4 tarding the rotation oi' one of the shafts, a bevel wear secured to the other shafts, a third shaft, a bevel gear rigid with the third shaft and ineshino with the bevel gear, means for revolving the last mentioned shaft, and a web adapted to be Wound from one spool to the other, said Web being transparent and formed with opaque portions.

ln testimony whereof l aiiX my signature in presence of t-Wo Witnesses'.
