RENT-COLLECTING MEANS No. 931,547. Specification of Application filed October 8,

To all whom it may concern:

Be it known that I, RICHARD YEARNEAU, a citizen of the United States, residing at Clark, in the county of Clark and State of South Dakota, have invented a new and useful Rent-Collecting Means for Telephone Service, of which the following is a specifi' cation.

The present inventionrelates to improvements in toll mechanism for telephones, and is in the nature of an improvement on the structure disclosed in my Patent Number 910628, of January 20, 1909.

The object of the present invention is to provide a structure that is more simple and compact, and will permit the use of a number of coins or checks of diflerent denominations.

An embodiment of the invention that is at present considered the preferable one is disclosed in the accompanying drawings, wherein Figure 1 is a diagran'miatic view of a portion of a telephone system, showing the novel controlling means installed. Fig. 2 is a sectional view on an enlarged scale through the casings of one of the rent-collecting devices, showing the mechanism in elevation. Fig. 3 is a cross sectional view 011 the line 33 of Fig. 2. Fig. 4: is a cross sectional view on the line H of Fig. 2. Fig. 5 is a longitudinal sectional view on the line 55 of Fig. 3. Fig. 6 is a plan view of a portion of the top of the casing. Fig. 7 is a diagrammatic view, illustrating the electrical connections at one of the instruments.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, a telephone system is disclosed, which includes a central station 8 and a plurality of instruments 9 having line connections 10 with said station. While a metallic circuit is disclosed, it will be evident that other circuits may be employed. Associated with each instrument is a rent collecting device, designated as a whole by the reference numeral 11. Each instrument consists of a casing 12 having a plurality of coin-receiving slots 13 preferably constructed to permit the passage of coins of different sizes, as illustrated in Fig. 6, though it will be evident that additional slots may be provided for a plurality of coins of the same denomination. Vithin CLARK, SOUTH DAKOTA.

FOR TELEPHONE SERVICE.

Letters Patent. Patented Aug. 1'7, 1909.

1908. Serial No. 456,776.

the casing and below the slots 13 is a block 14 of non-conducting material having a plu rality of coin guides or chutes 15 alined with the slots 13 and corresponding in cross sectional area thereto. Secured to the opposite sides of the casing 12 are tracks 16 on which reciprocates a frame 17 that is provided with a plurality of check-supporting plates 18, the whole forming practically a grid. The plates 18 are normally located below the lower ends of the guides or chutes 15, but are movable from beneath the same. To this end, the frame is connected to a depending finger 19 having an inwardly extending portion 20 that constitutes in effect a cam track. The upper end of the finger 19 is pivoted, as illustrated at 21 in a frame 22 that supports a spring motor including a spring 23, a master wheel 21, and a train of gearing connected to a speed governor fan 26. The wheel 24 has a projection 25 thereon in the form of a stud, and the cam track 20 is located in the path of movement of this stud. It will thus be evident that when the motor is operated, the wheel 24: will rotate, and the stud 25 engaging the cam track will cause a rearward movement of the finger 19. This will move the plates 18 out of their normal positions beneath the chutes. The return movement is secured by a spring 27 con nected to the frame 17, as clearly shown in Fig. 2. Under normal conditions, the motor is held against movement, and for this purpose, a holding arm 28 is employed having a teeth 29 that engages in any of a plu rality of notches 30 formed in the periphery of the wheel 24. This holding arm is pivoted as shown at 31 in the frame 22, and itis actuated by another arm 32, which rests upon the rearwardly extending pin 33 of an armature 34. This armature cooperates with the core of an electro-magnet 35 located in one corner of the casing. The electro-magnet is in an electric circuit, one line 30 of which may be grounded as shown, the other line 37 including a pair of spring contact elements 38 located in one of the check guides or chutes 15. This line 37 continues to the central station 8 where a magnetic generator 39 or other suitable source of electrical energy is located.

A short circuit is provided for eachinstrument, and is in the form of wires 40 connected to the line wires 10 and extending into the casing 12. One of the line wires 10 is connected to a contact bar 41 secured to one side of the block 14 while the other wire 40 is connected to a number of yielding con tact fingers 42 that extend across the bar 41, and have inturned terminals 43 extending into the guideways or chutes 15 and into the paths of movement of the checks or coins placed therein. Normally the fingers 42 are in engagement with the bar 41, as shown 1n Figs. 3 and 4, but when a coin or check placed in a guideway, the finger will be moved out of engagement with the bar. inasmuch the finger 42 which extends into the guideway or chute containing the fingers must not be electrically connected with said fingers 38, this particular finger 42 is preferably provided at its inner end with a contact head 43 of insulating material that is engaged by the adjacent finger 38 so that when a coin or check is located between the fingers 38, the latter are spread apart and one of said fingers pressing against the head 43, disengages the finger 42 from the bar 41.

The operation of the mechanism is substantially as follows. It will be evident that when there are no checks or coins in the guideways, the fingers 42 will be in engagement with the bar 41, and consequently the instrument will be short-circuited. Assuming for the purpose of explanation that the rent of the telephone instrument is one dollar and seventy-five cents a month, it will be evident that if a twenty-five cent piece is introduced into the proper slot 13, a fifty cent piece into the next and a silver dollar into the succeeding slot, these various coins will drop into the guidcways 15 and rest upon the supporting plates 18. as a result, the various spring fingers 42 will be held out of engagement with the bar 41, the short circuit 40 will consequently be broken, and the instrument will be in uninterrupted communication with the central station. At the same time it will also be evident that the circuit 37 through the electro-magnet 35, will be closed by the one dollar piece engaging both of the springs 38. When the end of the month comes or a succeeding pay ment is due, the operator at the central station has only to generate current in the circuit 37 by means of the magneto generator 39, whereupon the electro magnetor magnets 35 in said circuit will be energized, thus elevating the fingers 32 and the fingers 28. The motors being thereby released will be operated and the stud 25- engaging the cam track 20 of the finger 19 will cause the check or coin-supporting plates to be moved from under the above mentioned coins and the latter will drop into the bottom of the casing. Immediately therefore the spring fingers 42 will return to their original positions in engagement with the bar 41 and the instrument or instruments will be shortcircuited and cannot be again used until the subscriber places the proper amount in the various slots. In this connection, it will be evident that the number and variety of slots may be altered according to the amount of rental imposed.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is:
