Specification of Letters Patent.

Patented J nne a, 1912.

Application filed March 5, 1912. Serial No. 681,728.

To all whom it may concern:

Be it known that I, JASPER E. LEWIS, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Coin-Controlled Circuit-Closing Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in coin-in-the-slot, circuit controlling devices for motors adapted to drive fans, etc., and comprises a simple and efficient apparatus of this nature so constructed that a motor may be started and which is allowed to run for a predetermined length of time, then automatically stopped.

The invention comprises various details of construction and combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which Figure 1 is a sectional View transversely through a casing containing the operative parts of the apparatus whichare shown in top plan view. Fig. 2 is a view vertically through the casing, showing in side elevation the apparatus. Fig. 8 is a similar section looking at the opposite side of the apparatus, and Fig. 4. is a sectional view taken on line 4'4 of Fig. 1.

Reference now being had to the details of the. drawings by letter, A designates a platform, preferably of insulated material, mounted upon the standards A, and B is a casing containing the operative parts of the apparatus and provided with a drawer B adapted to receive the coins as, they are dropped from the slot B Resting upon the platform A is a frame C containing the operative parts of the motor which in the present instance is of the usual clock-work mechanism, consisting of a spring 0, one end of which is fastened to a shaft C and its other end secured to a winding shaft 0 to the squared end 0* of which, shown in tates with the shaft 1).

Fig. 3 of the drawings, a. key may be applled for the purpose of winding the spring, a suitable pawl and ratchet C and C bemg provided for holding the spring under tension. Fixedto the shaft carrying the sprlng is a gear wheel D which is in mesh with the pinion D upon the shaft D and a gear wheel D also fastened to the shaft D? is in meshwith a pinion D fixed to the shaft D which has keyed thereto a gear wheel D in mesh with a pinion D upon the shaft D A gear wheel D upon the shaft D is in mesh with a pinion D which ro- The gear wheel D is in mesh with a worm gear E, shown clearly in Fig. 3 of the drawings, and which is journaled in the bracket member E secured to the frame of the apparatus. The shaft upon which said worm gear is mounted is provided with a fan E Referring to Fig. 4 of the drawings there will be noted an angled lug F fastened at one end to the gear wheel D, the end F of which projects at right angles from the gear wheel to which it is fastened. A rock shaft, designated by letter H, is mounted in the opposite walls of the frame and has a hook H fixedv thereto, the end of which hook is adapted to be positioned in the path of the lug F, forming means whereby, when the wheel D and the shaft carrying the same make one revolution, said hook will engage the lug and stop the motor. A wire, designated by letter I, projects from the sliaft H and is adapted to contact with the shaft I mounted in the frame of the apparatus, thus tending to limit, the rotary movement of the shaft H in one direction.

Upon reference to Fig. 3 of the drawings, it .will be noted that an armature J is fastened at one end to the shaft H and, when the elect-ro-magnet K is energized, said armature will be drawn in contact therewith and cause the shaft H to rock sufficiently to throw the book which is fastened to the shaft I-I out of the path of the lug F, thus allowing the gear wheel D to rotate under the influence of the spring which has gear connections with the shaft to which the spring is attached.

Referring to Fig. 2 of the drawings there will be noted an angled operating lever N, the horizontal portion of which is journaled in openings in the frame of the motor, and N designates a plate which is provided with lugs N which are keyed to the horizontally disposed portion of the lever N. Said plate has a laterally projecting guard wing i shown in edge elevation in Fig. 2, and which is curved. Mounted upon the normally inclined face of the plate N is a curved block N, preferably of insulated material, adapted to hold a coin as it is dropped through the chute Q. A metallic strip N is interposed between the block N and the plate and a second insulation block N against which the coin is adapted to contact. A metallic plate O is supported parallel to the partition, as shown in Fig. 2 of the drawings, and fixed to the plate 0 is an angle plate O which carries the chute Q through which the coins are dropped and fastened upon an inclined portion of the plate O is a metallic plate P, of suitable conducting material, and which is held in place by means of a screw P and is mounted upon the insulating block P. A binding post, designated by letter R, is fastened to each end of said plate P and to which an electric wire R is connected and which wire is also connected with the binding post S with one pole of the electro-magnet, the other pole being connected with the binding post S to which the wire S is connected and which in turn is connected, through the medium of the wire S and binding post S with the longitudinally-movable, sliding contact plate S which is fastened to an insulating block S A disk, designated by letter T; is fastened to one end of the shaft D and has a recess T in the circumference thereof, against the circumference of which the metallic conductor strip S rides, thus forming a closed circuit which is broken when the recess in said disk comes in alinement with the strip S at a predetermined moment coincident with the stopping of the motor, thus shutting off the current.

Referring to Fig. 2 of the drawings, a standard V rises from the plate 0 and is positioned opposite an opening V and serves \to kick the coin 01f the support after the coin has been thrown forward by the rocking of the handle N, thence falling by gravity through an opening and into the drawer beneath. A spring X is fastened at X to the plate 0 and its other end to an arm N which is fixed to the horizontally- V disposed portion of the operating handle N,

.ings, a coin is dropped through the chute into the slot B and falling will be caught by the block N and, as the handle N is thrown forward, its horizontal portion will rock and cause the plate N to be thrown forward, carrying the coin with it. WVhen the coin comes in contact with the end P of the plate P, the circuit will be closed and the electro-magnet energized, drawing the armature in contact therewith, which act will cause the shaft upon which the armature is fixed to rock and the hook H will be thrown out of the path of the lug F, allowing the spring motor to cause the gear wheel D to make a complete revolution. The speed at which said wheel D will rotate is determined by the size of the intermeshing wheels and, when the wheel D shall have made a complete revolution, the recess in the disk will have come opposite and in alinement with the metallic strip S and out of contact with the disk which will close the circuit, allowing the armature to drop down from the magnet and the hook will be again positioned in the path of the lug F and, as it contacts therewith, the motor will stop. After the operating handle has been swung forward in the act of bringing the coin in contact to close the circuit and after pressure is released from the handle, the spring attached to the arm thereon will return the handle to its normal position and, as the coin comes in contact with the end of the member W, the coin will be kicked from off the block holding the same and fall by gravity into the boX below.

By the provision of an apparatus as shown and described, it will be noted that a simple and eflicient mechanism is afforded whereby a fan, for which the apparatus is especially adapted, may be caused to beoperated for a predetermined length of time, after which the motor will be automatically stopped.
