AUXILIARY SIGNALING-BOX.

SPECIFICATION forming part of Letters Patent No. 686,207, dated November 5, 1901'.

Application filed March 22, 1900- Serial No. 91662; (No model.)

To all whom it may concern.-

Be it known that I, CHARLES W. CORNELL, a

citizen of the United States, residing at East case by the winding up of the spring. Auxiliary apparatus has been before applied to boxes of this type and by which a box having been set or wound up may be operated from an auxiliary circuit leading to one or so more auxiliary stations. The auxiliary appliances'heretofore suggested for use with signaling-boxes of this type have been objectionable, partly because of the fact that the mechanism for starting the box is ex- 2 5 posed and is of a delicate character and there was danger of its being tampered with or of an efiort being made to start thebox be fore winding it up. Because of this fact the sector-boxes which have heretofore been provided with auxiliary mechanism have been liable to derangement.

The object of my present invention is to improve the auxiliary mechanism for use in connection with sector-boxes by which the con- 3 5 struction will be simplified and the objection noted overcome.

In order that my invention may be better understood, attention is directed to the accompanying drawings, forming a part of this specification, and in which Figure 1 is a face View of a portion of the inner case of a sector-box with my present attachments, illustrating so much of the box mechanism as is necessary for an understandingot my present improvements; Fig. 2, a

section on the line 2 2 of Fig. 1; Fig. 3, asection on the line 3 3 of Fig. 1 looking toward the left; Fig. 4, a plan view of the auxiliary mechanism, and Fig. 5 a detail view of the box-operating devices which are carried on the door of the inner casing and which result in the winding up of the box and the setting of the box mechanism.

In all of the above views corresponding parts are represented by the same numerals 5 5 of reference.

A cylindrical casing 1 is located Within the usual inner case and carries the box mech* anism, which in the present instance is of the sector type.

2 is a winding-lever keyed to a windingshaft 3, to which is secured a spring 4. A movement downward of the lever 2 winds the spring 4, and the return movement of the lever results in the operation of the box mechanism. This mechanism is provided with the usual shaft 5, carrying the signaling wheel 6, on which bear the contact-pens 7 in the signaling-circuit. The signal-shaft 5 carries a gear 8, by which it is driven, and on said gear is a stop-pin 9, into the path of which projects a tooth 10 to start and stop the box mechanism. The tooth 10 is carried on a lever 11, pivoted at 12' and carrying a curved lower extension 13. Cooperating with this extension is a pin 14, carried by a lever 15, which is keyed to the winding-shaft 3. When the spring is unwound and the lever 2 is in the position shown in full lines, Fig. 1, the pin 14: engages with the lower portion of the extremity 13 and maintains the tooth 1O locked in its position beneath the pin 9.

When the winding-lever 2 is moved downward to wind up the spring, as shown in dotted lines, the pin 14 will be withdrawn from the extension 13 and the tooth 10 will be held in engagement with the pin 9 by friction, so that the tooth may be withdrawn from that engagement to start the box.

With my present improvements the starting of the box is efiected by the movement of an auxiliary armature whether the signal is sent from the box in the first instance or from an auxiliary station. Mounted upon the in= ner casing of the box and within the outer box are the auxiliary magnets 16, the armature 17 of which is carried on a lever 18, pivoted on the rock-shaft 19. An arm 20 extends downward from the lever 18 and carries an insulating-block 21 at its lower end, which engages within a slotted head 22, carried by the lever 11. Normally the auxiliary circuit is closed on a weak battery, which is insufficient to result in the attraction of the armature 17 by the auxiliary magnets 16. By connecting additional batteries on the auxiliary circuit, as is now the practice, the armature 17 will be attracted, swinging the lever 18 and Withdrawing the tooth from the pin 9, so as to allow the box to start. The upper end of the lever 18 is provided with a tooth 23, with which a wedge 24, carried on a spring 25, engages, whereby the engagement of the wedge on one side of the tooth will hold the armature 17 normally retracted to prevent accidental disengagement of the tooth 10 from the pin 9, while when the wedge 24 engages the opposite side of the tooth 23 the toot-h 10 will be prevented from accidentally moving into the path of the pin 9 before the pin 14 results in the positive movement of the tooth 10 into the path of the pin 9 by its engagement with the inclined extension 13 of the lever 11.

It is the practice with auxiliary systems as now installed to provide at each auxiliary station a trouble-bell, which is brought into operation by the breaking of the auxiliary circuit. The ringing of this bell therefore, as it is now used, notifies the auxiliary operator that the auxiliary circuit has been disabled, so that repairs thereof can be made.

With my present improvement I utilize the trouble-bell at the auxiliary station for the purpose of notifying the operator thereat that an auxiliary signal has been received at and transmitted by the street-box, and I also utilize the trouble-bell for the purpose of offering a further notification to the operator at the auxiliary station when the street-box has been operated by directly pulling the box or from another auxiliary station. Thus when an alarm has been sent in by an operator at an auxiliary station he will be advised immediately of the transmission of the signal from the street-box, while if the trouble-bell commences to operate at other times the operator at the auxiliary station will know either that his particular auxiliary circuit has been disabled or that the street-box has been pulled, but has not been reset. In either instance the condition of the streetbox or of the auxiliary circuit requires attention. The operator at the auxiliary station will be enabled to determine by the continuous operation of his trouble-bell whether that attention has been given to the box or to the circuit. In order that these objects may be effected, I utilize a pair of contact-springs 26 26, the break'between which is adapted to be bridged normally by the upper end of a rod 27. The springs 26 are included in the auxiliary cir saao'r cuit, and when that circuit is in its normal closed condition the upper end of the rod 27 will be elevated. The rod 27 leads down to the case 1 and is provided at its lower end with a head 28, adjustable on the threads 29 and adapted to be engaged by an arm 30, pivoted to the end of the lever 15. A pin 31, carried by the arm 30 beyond its pivot, engages the under side of the lever when the winding-shaft is turned, so that the arm will act practically as an extension of the lever 15 at the right of its pivot and will engage beneath the head 28 of the rod 27 to elevate'the latter and close the auxiliary circuit at the springs 26 26. As the windingshaft returns to elevate the end of the lever 2 the arm 30 will be withdrawn from the rod 27 to allow the latter to break the auxiliary circuit at the springs 26, and said arm will descend until it engages one of the cross-bars 2 of the box mechanism to prevent further movement of the said arm, which then moves relatively to the lever 15. This construction effects a greater saving of space within the inner case 1 than would be secured if the arm 30 were rigidly secured or integrally formed with the lever 15, as will be obvious. Inorder to operate the box mechanism at the box itself, I pivota lever 33, having an outturned finger 34, which is located within a slot or recess 35, formed in the inner casing. The lever 33 carries a rod 36, which engages the front of the armature 17, so that when the finger 34 is moved to the right in Fig. 1 the armature 17 will be moved toward the magnet to trip the box, as explained. The return movement of the lever 33 is limited by a pin 37, which engages the said lever, as shown. The cover of the inner box carries a lever 38, pivoted on its inner face and with its upper end working in the recess 35, so as to engage the finger 34 of the lever 33 when the lever 38 is actuated. The lever 38 is engaged by a hook 39, which slides between two pins 40 40 on the cover and which is connected at its lower end to a lever 41, to which the hook 42 is secured. This hook projects through a slot in the cover of the inner casing and is adapted to be pulled down by hand. Pivoted to the lever 41 is a gravity-pawl 43, carrying a weight 44, which normally tends to throw the pawl into the position shown in dotted lines, Fig. 5. The lower end of the pawl 43 is adapted to engage with the end of the lever 2, and these parts are maintained in that engagement by friction during the descent of the hook 42 in the pulling of the box. A spring 45 engages the upper end of the pawl 44, when the lever 41 is returned to its normal position by a spring 46 to throw the pawl 43 in the position shown in full lines,

Fig. 5, and to thereby engage the outer end of the lever 2. By reason of this construction the pawl 43 can only engage the end of the lever 2 when the lever 41 is elevated to its normal position and when the lever 2 has been returned by the unwinding of the spring and the sending in of the signal, since at this point the pawl and the lever 2 are capable of engagement. By reason of this construction it becomes impossible, therefore, to depress the lever 2 by pulling down the hook during the sending in of a signal, and the operator is required to wait until the signal has been sent in before the signal can be repeated.

The operation of the box will be as follows: Normally the parts occupy the position shown in dotted lines, Fig; 1, with the spring wound and the arm 30 engaging beneath the head 28 to elevate the rod 27 and close the auxiliary circuit at the springs 26. The tooth 10 is in engagement beneath pin 9, which locks the box mechanism. The wedge 24: is on the left side of the tooth 23, and the armature 17 is in a retracted position. The auxiliary circuit is normally closed on a weak battery, which is insufficient to result in the tripping of the box, but is suflicient to prevent the sounding of the trouble-bell. If an alarm is to be sent in at the said station, the hook 42 is pulled down. Assuming the box to be wound, the pawl t3 will not engage the lever 2, since the lever will be depressed; but the movement downward of the lever 41 will do press the hook 39, which, working between the pins 40, cannot follow the swing of the lever 38, but will be disengaged from said lever near the start in the movement of the hook. The short movement which is thus imparted to the lever 38 will move the lever 33, swinging the armature 17 toward the auxiliary magnets and withdrawing the tooth 10 from the pin 9, thus allowing the box mechanism to start. Ordinarily .the signalingshaft 5 makes three or four complete rotations. Near the end of the signaling operation the pin 14, which moves downward as the winding-lever 2 ascends, will engage the extension 13 of the lever 12 and return the tooth 10 again into the path of the pin 9, which will once more engage the said pin and bring the box mechanism to rest. This resetting also retracts the armature 17 to its original position. Immediately after the box mechanism starts and the winding-lever 2 has commenced to ascend the arm 30 will permit the rod 27 to be withdrawn from contact with the spring 26 to break the auxiliary circuit, thus informing the operator at each auxiliary station that the street-box has been operated. The trouble-bell at each auxiliary station will therefore sound so long as the street-box remains unwound. B y depressing the lever 2 to wind up the street-box the arm 30 will engage beneath the rod 27 to again close the auxiliary circuit at the contacts 26 26, thus stopping the operation of the troublebell. \Vhen the signal is to be sent in at the street-box from anauxiliary station, theclosing of the auxiliary circuit upon the additional batteries. as is common, will result in the attraction of the armature 17 to withdraw the tooth 10 from the pin 9, allowing the box to start. Immediately afterthe box has commenced to-operate, or as soon, therefore, as may be desired, by properly proportioning the parts the auxiliary circuit will be broken at the contacts 26 and the sounding of the trouble-bell will therefore immediately notify the operator that the signal has been-received and is being actually transmitted. The trouble-bell will sound, therefore, until the box has been again wound ready for the reception of another signal.
