COIN-CONTROLLED MECHANISM.

Specification of Letters Patent. Application filed. October 25, 1906.

Patented Feb. 23, 1909.

Serial No. 340,560.

To all whom it may concern:

Be it known that I, JOHN C. FREDELL, citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new i and useful 1m provements in Coin-Controlled Mechanism, of which the following is a speci fication.

This invention relates to coin controlled mechanism for intermittently and electricall operated devices.

11 a patent granted to John C. Fredell, Sept. 4, 1906, numbered 830,217 there is disclosed an electrically controlled optical appliance which embodies a shutter opened and closed by electro magnets.

The present invention has for an object to provide a coin controlled manually operated means for storing power in a motor w ich effects the closing of the circuits controlling the shutter electro magnets.

Other and further objects will appear in the following description and will be more particularly pointe out in the appended claims.

In the drawings :Figure 1 is an elevation of my invention. Fig. is a side elevation. Fig. 3 is a detail view of the contact operating disk. Fig. 4 is a detail view of the sector connected to the spring shaft. Fig. 5 is a top view of the sector showing its relation to the registering mechanism.

Referring more particularly to the drawings, A indicates a frame u on which is mounted a spring shaft 1. lhis shaft has oneend of a volute spring 2 secured thereto and carries a gear 3 to which it is connected by a pawl and ratchet (not shown) permitting t e shaft to be turned in the direction of winding the spring, without rotating the gear 3. If, however, the spring shaft rotates under the action of the spring 2, the gear 3 ro tates and through the medium of a reducing gearing 4, 5, 6, connects with a fan blade 7 which acts as a governor for the motor spring 2. Motor shaft 1 also carries a pinion 8 with which meshes a sector 9 mounted on a coin controlled shaft 10 journaled in frame A. The ends 11 and 12 of the sector are each adapted to engage one arm 13 of a bell crank lever, the other arm 14 being connected by a link 15 with an arm registering mechanism 18. The bell crank lever is held in one position by a coil spring 19 which is connected theframe A.

16 on the shaft 17 of the to the arm 14 and to l Rigidly secured to the shaft 10 is a disk 20 a which carries an extension 21 on which is pivotally mounted a trip 22 yieldingly held against a stud 23 on tie extension 21 by means of a spring 24. The tri 22, when the disk is rotated by the manna y operated means to be hereafter described, passes over a Cpair of spaced movable contacts 25 and 26 a apted to respectivel engage contacts 27 and 28 and thus close the circuits to the shutter controlling electro magnets. The movable contacts 25 and 26 are normally held away from their fixed contacts, by means of springs 29 and 30 respectively and each has an inclined face 31 and 32 with which the trip 22 engages on its return movement, thereby causing the making of the circuits.

The manually operated means for storing power in the s ring motor and at the same time shifting tie trip 22, comprises a cran handle 33 loosely journaled on the coin controlled shaft 10 and connected by a sleeve 34, arranged about the said shaft, with a two armed member. One arm 35 of said member has connected to it, one end of a coil spring 36, the other end of the coil s ring being connected to the frame A. Tie other arm 37 of the two armed member carries a dog 38 which lies on the periphery of the disk 20, being held thereagainst by a spring 39, the disk being provided with a notch 40 in which the dog 18 adapted to enter to establish connection between the crank handle and the disk and thereby rotate the sector and store power inspring 2.

To prevent the dog 38 entering into connection with the disk 20, a disk 41 is journaled 11)011 the coin controlled shaft 10. This disk is provided with a notch 42 which, when alined with notch 40, permits dog 38 to enter notch 40, but which prevents the dog entering the notch 40 when said disk 41 is in any other position. The disk 41 normally lies in the position shown in Fig. 1 and has its movements limited by a lug 43 which projects from the disk 20 into an arcuate slot 44 in the disk 41. A volute spring 45, positioned between the two disks, is secured at one end to the shaft 10 and at its other end to the disk 41. This spring 45 tends to hold the disk 41 so that the notch 42 is alined with notch 40. The disk 41, however, is held away from this position by means of a trip 46 pivoted to one side of a coin chute 47 and engaging below a lug 48 on the disk 41, one face of the lug 48 and one face of the r the time occupied by the trip 22 in moving '13 of the bell crank lever and returns it to its combination with a shaft, of a crank handle journaled on the shaft, a disk secured to the shaft, a dog secured to the crank handle and adapted to engage the disk, and a normally locked disk controlling the engagement of the dog with the disk first named. v 2. In a coin controlled mechanism, the combination with a shaft, of a crank handle The operation of the invention is as follows: j o'urnaled 0n the shaft, a disk secured to the Assuming the parts to be in the position shaft, a dog secured to the crank handle and shown in Fig. 1 and a coin to be dropped into adapted to engage the disk, a disk journaled the coin chute 47, the finger 52 is engaged on the shaft and controlling the engagement and moves the trip 46, against the action of of the dog with the first named disk, a spring its spring 51, out of the path of the lug or pin acting to move said second named disk to 48 on disk 41. The disk 41, being now freed, permit the first named disk to be engaged by moves under the action of its spring 45 so as the dog, and locking mechanism for the to aline its notch 42 with the notch 40 on the second named disk.

The disk 41 is thus dle and adapted to engage the disk, a disk returned by the crank handle to its original journaled on the shaft and controlling the position, the inclined face of its lug engaging engagement of the dog with the first named the inclined face of the trip 46, moving the disk, a spring acting to move said second latter out of the path of the former so that named disk to permit the first named disk to the trip may engage behind the lug'and hold be engaged by the dog, and a trip normally the disk 41 against returning.
