JOI-IN M. SCI-IILLING .AND HARLEY A. BALDWIN, 0F CHICAGO, ILLINOIS.
GRAVITY-MOTOR.
Application filed March 21, 1912.
To all whom t may concern Be it known that We, JoHN M. SernLLiNo and HARLEY A. BALDWIN, citizens of the United States, residing at Chicago, 1n the county of Cook and State of lllinois, have invented certain new and useful Improvements in Gravity-Motors, of which the following is a specification.
rlhis invention relates to improvements in gravity motors and its object is to produce a simple practical device of this class that can be readily adapted to a variety of uses.
One use of the device is to suspend and rotate at adjustable speed a card advertise nient or similar advertising announcement in a show window or other suitable place.
The essential features of the motor are a spiral drive shaft which is disposed between a pair of adjacent feed plates with each of which it contacts and by which a rotary inotion is imparted to said shaft as it descends but which motion is entirely obviated as the said shaft is returned to its original positie-n against the force of gravity.
A complete description of the invention will be had in the following specification, its novelty pointed out in the appended claims, and illustrated in the accompanying drawing which forms a part of said specification and in Which- Figure l is a vertical sectional elevation of one embodiment of our gravity motor. Fig. 2 is a top plan of the same. Fig. 3 is a transverse section through Fig. l on line 3-3. Fig. 4t is a section taken on line l-t of Fig. 3. Fig. 5 is a perspective of one of the feed plates employed.
Like reference characters indicate corresponding parts throughout the several views.
Our invention comprises essentially a base plate l formed with a central aperture 2 and Which may be provided With a pair of legs or supports 8 and et to rest upon an apertured base 5 of a hollenl housing 6 in which our contrivance operates. rlhe housing 6, which is provided with a top A, is apertured or punched out as at 7 7 and the material so punched out may be pressed down upon the base plate 1 as shown in Fig. 3 to hold the same in position. Within the apertures 7, 7 arms S, 8 of the base 5 are projected thereby holding the said base in position.
Upon the base plate 1 a pair of adjacentl feed plates 9, 9 are disposed. Each plate is provided With a pair of terminal legs 10, l0

that depend through apertures in the base plate the width of the legs being less than that of the said plate so that a portion 11 of said plate forms a lip that projects beyond the legs as shown in Fig. 5. rlhe plates are so placed upon the base plate l that the lips l1, 11 are directly opposite each other and oscillation of said plates upon their relatively reinote edges is possible.
lf2 is the spiral drive shaft that is disposed between the opposite lips l1, l1 of the adjacent plates t), E) so that it contacts with each of the said lips. One end of the shaft 12 is secured to a swivel l?) in the housing (3 and the other end to any suitable clasp or hook lll by which an advertising card or similar device l5 is retained. The swivel 13 is suspended 'within the housing G by a rope 16. rlhe weight at the lower end of the spiral shaft regulates the speed of that shaft between the plates t), t) as it descends. The greater this Weight the faster the shaft rotates.
ln Fig. l the device is shown in operation, the feed plates imparting a rotary vertical motion to the descending shaft; when the shaft is returned, after its descent, by the rope 1G the said shaft raises the adjacent edges of the plates t), 9 which operation permits its free passage to its original position.
W hat we clailn is 1. ln a gravity motor, an apertured base plate suitably supported, a spiral shaft extending therethrough and automatic feed mechanism carried by said base plate operatively engaging said spiral shaft whereby rotary motion is imparted to the latter in its descent but obviat'ed in its return.
2. ln a gravity motor, an apertured base plate suitably supported, a spiral shaft extending through said base plate and automatie feed mechanism carried by said base plate operatively engaging said spiral shaft whereby rotary motion is imparted to the latter.
3. In a gravity motor, an apertured base plate suitably supported, a spiral shaft extending through said base plate and a pair of movable feed plates carried by said base plate whereby rotary motion is imparted to the said spiral shaft.
t. In a gravity motor, an apertured base plate suitably supported, a spiral shaft extending through the said base plate and a pair of movable feed plates carried by said base plate operatively engaging Said spiral shaft whereby rotary motion is imparted to the latter.
5. In a gravity motor, an apertured base plate suitably supported, a spiral shaft eX- tending therethrough, a pair of movable feed plates, formed with integral legs projeoting through the said base plate, opern atively engaging the said spiral shaft whereby rotary motion is imparted to the latter.
6. ln a gravity motor, a housing, an apertured base plate mounted therein, a spiral shaft extending through said base plate and one end of said housing, a pair of movable feed plates Carried by said base plate operatively engaging said spiral shaft whereby rotary motion is imparted to the Same.
In testimony that we olairn the foregoing as our own we have hereto affixed our signatures in the presence of tvvo subscribing witnesses.
