Application filed March 20, 1917. Serial No. 155,975.

To a whom it may concern:

Be it known that I, ABRAHAM REUBEN- sTONE. a citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Attachments for Telephones, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to attachments for telephones and the object thereof is to provide an improveddevice of this class which is designed to prevent overcharges, mischarges, and fraudulent charges by the companv. and to keep a true and accurate account of all calls for which the user of the telephone is liable, and which is also designed to be attached to and used in connection with the transmitter of the telephone, and which forms a part thereof when in use: a further object being to provide an attachment for telephones which will register all outgoing calls made by the owner or user of the telephone, and which will cancel all outgoing calls not received by the party or parties on whom they are made, and which will also register all incoming calls or calls received by the owner or user of the telephone and which controls the operation of the transmitter and must be operated for the purpose of registering outgoing and incoming calls when the transmitter is used and before using the transmitter for making Or receiving calls; a still further object being to provide an attachment for telephones of the class specified in which the registering mechanism is controlled by the receiver arm of the telephone; and with these and other objects in view the invention consists in an attachment for telephones of the class specified, constructed and operat ing as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which:

Figure 1 is a front view of the transmitter portion of a telephone but showing my invention attached thereto;

"Fig. 7 a partial section on the line 7-7 of Fig. 4; and

Fig. 8 a detail View of a part of the operative mechanism which I employ.

In the drawing and especially Figs. 1, 2 and 4, I have shown at aa telephone standard of the usual or any desired form to the top of which is pivoted the usual transmitter a and pivotally mounted in one side of the standard a is a receiver arm a from which is suspended a receiver a The transmitter a is provided with the usual mouthpiece a which, in my improvement, is preferably secured in the front portion of a casing 7) as hereinafter described.

The casing Z2 is cup-shaped in form and is adapted to be passed over the transmitter a and secured thereto by compressing two ears 5 bent from the material of said casing on the opposite sides of a slotted portion 72 in the bottom of said casing, said ears being compressed by a bolt or screw 6 passed therethrough as clearly indicated in Figs. 3 and 6. The central front portion of the casing 72 is provided with a threaded aperture 6 in which the mouth-piece a is mounted. and above and on the opposite sides of said aperture, the casing is provided with apertures or openings b and b rearwardly of which are mounted registering devices 0 and c of any desired form and construction.

Mounted within the casing Z) and rearwardly of the aperture 6 thereof are shutters (I pivoted at (Z to a pin or stud mounted in the casing and on the rear end of which is mounted a spring (Z the ends d of which are directed upwardly and are adapted to operate in connection with inwardly directed flaps (Z integral with the shutters d, said spring serving to separate the shutters (Z, as hereinafter described. The top side portions of the shutters are cut out as shown at (Z and at the lower end of said cut-out portions, the shutters are provided with backi a link a, the lower end of which is provided with a fork-shaped "end 6 adapted to engage or receive the receiver arm a of the telephone, as clearly indicated in Fig. 4.

' The front end of the lever e is provided witha cylindrical head a pivoted in lugs 0 connected with a lock plate e having oppositely directed arms 6' and e, and With central arc-shaped portions 6 which oper-, ate in connection with the flaps d on the shutters d and serve to hold the shutters in their closed position against the tension of the spring d, as hereinafter described.

The front of the casing 12 is provided on ,the opposite sides of the aperture b therein .i'vith studs 5 to which are pivotally connected p'ush'button devices f and g normally held in a raised position by springs f and 9 The inner ends of the push button devices f and g are provided respectively w1th L-shaped arms f and g and the central portions of said devices are provided with downwardly directed fingers f and g which operate in connection with the arms 6' and e as hereinafter described.

Pawls h and h are pivoted to the studs 6 outwardly of the push button devices 1 and g and are free to move on said pivot, and the inner ends thereof are provided with backwar'dly directed portions k and it respectively. y

The shafts of the registering devices a and 0 are provided with sleeves 0 and 0* to the rear ends of. which are pivoted plates 71 and 6 provided with central cut-out portions 2' and i adapted to bear onpins or studs z? secured to I a supplemental inner casing j. The lower ends of vthe plates 7; and i are provided with off-set portions 1' and '5 between which and the cut-out portions 2' and 2" said plates are provided with shoulders i and i".

The L-shaped arms 7' and g are adapted to operate in connection with the shoulders i and i of the plates '2' and i to raise said plates on the depression or downward movement'of the push button devices against thetension of the springs is connected with said plates and with thepins or studs 1:. Said studs are also provided with fl-at springs which operate on the outer faces of the plates z' and 2' and serve to move said plates inwardly, ashereinafter described.

1 also provide levers m and m pivoted to pins 0?. secured to the supplemental inner casing j, the inner end of the lever on being provided with a pin m which operates in connection with an elongated slot m in the a spring 0 corresponding end of the lever m vThe outer ends of said levers are provided with u-shaped portions m" and m in connection with which the inwardly directed portions 7L3 and h of the pawls h and k operate. By means of this construction the operation of one push button to open the shutters d is facilitated as hereinafter described.

The registering devices 0 or the shaft thereof, in the construction shown, is also provided with a supplemental sleeve 0 similar to the sleeves c and 0 and a push button device 0. is mounted in the central top portion of the casing b, and in the supple.

mental casing j, and normally projected by The lower end of the push button device is providedwith a fingero which operates in connection with the sleeve 0 or a projection 0 thereon whereby, on the inward or downward movement of said push button device the registering device 0 will be operated to cancel a call reviously re istered as hereinafter described.

he locking link 7) is connected with the arm 6 of the lock plate 6 and extends upwardly and has a bearing on one of the pins n, said pin assing through an elongated slot 12 thereln, and the upper end of the link p is provided with an L-shaped portion p which operates in connection with the finger 0 to lock the'push button device against downward movement when the parts are in their normal position, or in the position shown in Figs.v 1 to 5 inclusive. The link p in conjunction with the arms 6 and e operate as lock devices or devices for locking the push button devices 7, g, and 0 against movement until the receiver a has been removed from the arm a as hereinafter described.

The operation of my improved registering mechanism will be readily understood by all those skilled in the art when taken in connection with the foregoing specification and the accompanying drawings and the .lever e from the position shown in full lines to the position indicated in dotted lines, which operation moves the lock plate 6 and the arms 6 and 6 thereof downwardly into the position shown in Fig. 6, and at this .point the shutters d are held against outward movement by the inner faces of the pawls h and if, as clearly indicated in .Figs. 3 and 5, and by reason of the shutters d being closed it iis impossible to use the telephone, or to speak through the transmitter so as to be heard by central until said shutters are separated or opened.

As indicated in Fig. 1, the face of the casing b is provided adjacent to the push but-ton devices f and g with the lettering incoming and outgoing respectively and adjacent to the'push button device 0, the face of the casing is provided with the words To cancel outgoing not received. In view of the fact that the party using the telephone is sending an outgoing call, the push button device 9 is forced downwardly by hand into the position shown in Fig. 6, which operation releases the pawls h and b from the shutters (Z, and the spring (Z moves said shutters into the position shown in Fig. 6, or to their open position. The pawls are moved upwardly to accomplish the. above result by the L-shaped arm raising the pawl k in which operation the lever 771?, or the U-shaped end mthereof is raised and the corresponding U-shaped end m of the lever m is raised by reason of the connection of said levers at m and m*, and the lever m raises the pawl h at the same time as the pawl k is moved upwardly, as will be readily understood.

In the above described downward movement of the push button device 9, the plate 1' is moved upwardly by the arm to operate the registering device 0 as indicated in Fig. 6 and register another call, and in the movement of the shutters cl from their closed to their open position the plates 2' and 2' swing outwardly into the position shown in Fig. 6 by reason of the backwardly directed fingers (Z engaging the oflset portions 1' and i of said plates. The plates i and 2' are held in this position by the shutters (Z until said shutters are returned to their normal or closed position, and it will be noted that in the position of the parts shown in Fig. 6, the push button device 5 will be returned to its normal position by the spring 9 and the, same may be manipulated freely without danger of registering a call by reason of the fact that the plate 2' is held out of engagement therewith.

After the call has been completed and the receiver a is placed on the arm a and said arm moved downwardly in the usual man ner, this last operation of the arm returns the lever e from its dotted line position to the full line position and moves the lock plate 6 pivoted to the front end thereof upwardly, which operation moves the shutters (Z inwardly to close the same, and the pawls h and 72 drop into position to lock said shutters in their closed position, and the plates 2' and. i are moved inwardly by the springs or, in short, the parts (Z, g, 2', F, it, h m, m and p are returned into the position shown in Figs. 1 to 5 inclusive, or their normal position.

Should the party making the above call not have received the desired number, said call may be canceled by moving the push button 0 inwardly to operate the registering device to cancel a call, or the call previously registered by the upward movement of the plate i This operation of the push button 0 may be performed before placing the receiver a on the arm a, but if the party should forget to cancel a call before placing the receiver on the receiver arm, the receiver may be again removed from the arm and the button 0 manipulated without interfering with the other mechanism in any way, it being essential to remove the receiver arm in order to withdraw the locking link 79 from the finger 0 of the push button 0.

()n receiving a call the above operation of sending a call will be followed precisely with the exception that the push button device f is manipulated instead of the push button device g, but the operation of the mechanism will be in all respects the same as will be readily understood on a consideration of Figs. 3, 5 and 6 of the drawing.

From the foregoing description, it will be noted that the push button devices f, g, and 0 are normally locked against movement, and in this way it is impossible to register or to operate the registering devices and without raising, or removing the receiver a from the arm (L3, as hereinbefore set out, and it is also impossible to register-a call whether incoming or outgoing on the devices 0 and when the parts of my improved mechanism are in the position shown in Fig. 6 with either of the push button devices fg in the depressed position.

It will also be seen that my improved attachment for telephones forms, when in use, a part of the transmitter and controls the operation of the transmitter and must be operated for the purpose of registering outgoing and incoming calls when the transmitter is used and before using the transmitter for making or receiving calls and the word controls as used in the appended claims means that the registering device must be operated before outgoing calls can be made or incoming calls received, and that the shutters (Z actually control the operation of the transmitter by opening and closing the same; and while I have shown and de scribed my call registering device for use in connection with the transmitter of a telephone, and also for use in connection with the receiver arm, in the construction shown and described, the receiver arm normally serves to hold the shutters in a closed position, but my invention is not limited to the use of the receiver arm, or the connection of said arm with the operative parts of the attachment or registering device for this purpose, and while I have shown and described the construction which I prefer at what I claim as new and desire to secure by Letters Patent, is
