SIGNALING APPARATUS- SPECIFICATION forming part of Letters Patent No. 751,071, dated February 2, 1904- Application tiled March 19, 1903.

To @ZZ whom, it 17mg concern:

Beit known that I, EDWIN L. GRAUEL, a citizen ofthe United States,residing at Rochester, in the county of Monroe, State of NewYork, have invented certain new and useful Improvements in Make-and-Break Signaling Apparatus; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure l is a plan view of the apparatus, the parts being in the relative positions they occupy when the mechanism is not in operation. Fig'. 2 is a vertical central section taken through the upper or driving axle of the device and looking in the direction of the arrow, Fig. l, the upper interior axle and the lower axle and its pinion being in side elevation. Fig. 3 is a section on the line 3 3, Fig. l, looking toward the operating crank or handle. Fig. 4 is an end elevation of the device, the electric brush being in contact with the dead or insulated segment of the commutator. Fig. 5. is a view similar to Fig. 4, the electric brush being on the live or metal segment of the commutator.

My invention relates to the construction of Serial No. 148,563. (No model.)

make-and-break signaling apparatus for calling upon the relays of telegraph-lines when it is desired to annunciate a rapid, steady, and extended signal which vshall be unmistakable in its character, such device being permanently in series with the line-wire and adapted when actuated to make and breakthe circuit of such line-wire and to automatically close such circuit when the apparatus is not in operation.

To this end the main feature of my invention embraces in combination a spring-contact member, a spring-contact projecting core or insulated plug adapted to be projected longitudinally by the rotation of a driving-axle, a brush mounted upon said spring-contact mem-V ber, and a commutator having insulated and uninsulated sections or segments rotatable simultaneously with the driving-axle whereby when the mechanism is operated a regular and well-defined intermittent signal will be announced upon the relays of the line-wire with with which the device is in series.

There are other minor features of invention, all as will hereinafter more fully appear.

I will now proceed to describe my invention more fully, so that others skilled in the art to which it appertains may apply the same.

In the drawings, A is a metallic frame, in the upper portion of which is journaled a hollow axle B, said axle having a'transverse peripheral slot lb and a longitudinal peripheral slot 2b. Secured to the hollow axle B by a spline 3b or in other suitable manner is a driving gear-wheel C, said gear-wheel C havingo eninvs 1e into which roject hws or stops ld, which are integral with theV driving clutch-cap D and which when the crank E is rotated engage the walls of the openings lc to positively drivel the gear-wheel C and the pinion meshing therewith. Within the pocket H, between the members D and C, is a spring F, said spring being secured at one end to the driving gear-wheel C, as at 2c, and at the other end to the clutch-cap D, as at 2d, said spring being adapted to be put under strain by the relative movement of the clutch-cap D and gearwheel C, which occurs at the initial movement of the crank E, the relative movements of the parts D and C causing a corresponding relative rotation of the hollow axle B and its interior core-projecting axle G, which latter revolves with the crank E and clutch-cap D.

Secured to the hollow axle B by a set-screw lk or in other suitable manner is a collar K, against which and the inner side of the side frame A bears a spring L, said spring by its frictional bearing between the frame and the collar K creating suilicient resistance to allow the spring F to be put under strain. The core or plug projecting axle `Gr is provided with a dowel or guide-lug lg, which projects into the peripheral slot lb of the axle B, and said slot prevents any longitudinal motion of the axle G. The end of theaxle G which terminates within the hollow axle B is provided with a double-inclined groove 2g, into which ts the correspondingly reversely inclined end lp of the insulated core or plug P, said plug P being also provided with a dowel or guide-lug 2p, which projects into the longitudinal peripheral slot 2b of the hollow axle B and which permits the relative longitudinal movement of said plug P and hollow axle B.

Meshing with driving gear-wheel C is a pinion Q, which is secured to the axle R, said axle R being journaled in the Jframe A and having at its opposite end the commutator S, which latter is composed of alternate segments lS 2s, the former being metallic and connected to the axle R by the screw 3s and the latter being of insulating material.

T is an electric brush which is mounted upon the spring-contact member V and which bears upon the periphery of the commutator S; but said brush may be mounted in any other manner, provided it be insulated from the frame A and electrically connected with the spring-contact member V.

Mounted upon the frame A and insulated therefrom by an insulating member W is a spring-contact member V, which when the mechanism is not in operation contacts the outer end of the hollow axle B, thus electrically connecting said spring-contact member V with the frame A, (see Fig. 1,) but which when the mechanism is in operation is forced out of contact with the end of said axle B by the projection of the insulated core or plug P, thus opening the circuit through the springcontact member V and frame A.

X and Y are portions of the line-wire of the circuit the energy of which it is desired to inuence by the operation of the device, said wires X and Y being respectively connected to the spring-contact member V, as at l and to the frame A, as at ly.

For the purpose of lubricating the bearings of hollow axle B oil-ports b b are provided, and dust-guards a a for the several journals may be also provided, if desired.

The construction of the device being substantially as herein pointed out, its operation will be as follows: When the device is not in operation, it will readily be seen that the circuit from X to Y is always closed through spring-contact member V, hollow axle B, and thence through frame A, in which said hollow axle B is journaled to the binding-post ly, and thence to Y. Upon actuating the operating-crank or handle E of the device the clutch-cap D and interior core or insulatedplug projecting axle first rotate relative to the driving gear-wheel C and hollow axle B, the latter members being held against rotating by the frictional contact of the spring L upon the collar K and frame A, and this relative rotation of the parts before mentioned continues, thus putting the spring F under strain until the lugs or stops l1 of the clutch-cap D engage the walls of the openings lc of the driving gear-wheel C, when clutch-cap D, gear-wheel C, and axles B and G revolve in unison. The relative rotation of the parts above referred to causes the incline 2g of the plug or core projecting axle G to act upon the reversely-inclined end lp of the insulated core or plug P, thus projecting said core or plug longitudinally or' the hollow axle B, in which direction relative to said axle B it may only move on account of the dowel or guidepin 2p and longitudinal peripheral slot 2b, with the result that the spring-contact member V is unseated from the end of the hollow axle B and the circuit which was normally closed through such spring-contact member, thence through the hollow axle B, and frame A is broken at this point and remains open during the continued operation of the device and until power ceases to be applied to the operatingcrank E, when the energy stored in the spring F by the initial relative rotation of the clutchcap D, gear wheel C, and their respective axles Gr and B causes a relative rotation of the same parts, but in a reverse direction, thus permitting the spring-contact member V to return the insulated core or plug P to its inoperative position and thereby automatically close the circuit through such spring-contact member V, hollow axle B, and frame A. The insulated core or plug P having been projected as above described and the spring-cap D and driving gear-wheel C being driven in unison by the continued application of power to the operative crank or handle E, it will be seen that the commutator S is caused to revolve through the agency of pinion Q, which meshes with driving gear-wheel C and axle R, whereby the insulated and uninsulated segments of the commutator S are alternately brought into contact with the brush T, and the circuit from X to Y is either open, as when the brush is upon the insulated or dead segment 2s, or closed, as when the brush is upon the uninsulated or live segment l5, in which latter case the circuit is closed from X to Y through the lower portion of the springcontact member V, brush T, uninsulated com- IOO mutator -segment 1S, screw 3s, commutatoraxle R, and frame A to binding-post ly, and thence to Y. vA well-delined, rapid, and extended signal may thus be announced upon any instruments in the circuit with which this device is placed in series which would be iniiuenced by intermittently interrupting the energy of such circuit.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
