SIGNALING AND REGISTERING ATTACHMENT FOR REVERSlNG FURNACES.

SPECIFICATION forming part of Letters Patent No. 264510, dated September 19,188;

(No model.)

To all whom tt may concrn Be it known that I, OGDEN BoL'roN, of Canton, in the County of Stark and State of Ohio, have invented a new and useful Improvement in Signaling and Registering Attachments for Reversin g Furnaces; and 1 do hereby declare the following to be a full, clear, and exact description thereof.

My invention consists in connecting to the reversing mechanism of a reversing furnace a clock-work, which, at the proper periods,closes the circuit of an electric bell to give the signal l'orreversing the furnace, and which also feeds a strip of paper or other suitable material in the path ot' a point attach'ed to the reversinglever, so that upon the movement of the lever in reversing the furuace the point shall puneture the paper, and so record the number and regularity of the reversals, and, as the rate of feed is definite, also the time of such reversals.

To enable others skilled in the art to make and use my invention, I will now describe it by reference to the accompanying drawings, in which- Figure l is a front view of the attachment. Fig. 2 is an edge or side View, and Figs. 3 and et are similar Views of the same as applied to several furnaces.

Like letters of reference indicate like parts in each.

The reversing-lever in Figs. l and 2 is indicated at a. From it a rod, b, extends and is pivoted to the lower end of a pivoted link, c. The rod I) is pivotally attached to the lever a, the pin extending through a slot, a', in the lever for the purpose of enabling it to be attaehed farther from or nearer to the aXis of the lever, as it may be necessary to give the link c a longer or shorter throw. The link c is pivoted to a suitable lug or bearin g, (l, and is slotted, as at c'.

Fastened to the end of a rod, e, is a wrist or pin, c', which extends through the slot e', and is Secured in the desired position therein by a nut, 6 on its outer end. At its other end the rod e is pivotally connected to a rod, f, which passes through a guide, g, and at its upper end has a hoolr,f', by which it is attached to a spring, h. The purpose of the slot c' is to enable the wrist e' to be Secured to the link at any desired point. The rodfextends upinto a case, i, in which also the guide g is placed. In this case is a clock-wo'k, to the frame of which an electric wire, lt, extending from a suitable battery, is connected. The wheels ot' the clock-worlrj and its frame are eleetrically connected; and upon one of the Wheels l are projecting-pins l'.

At the side of the case t', in clamping-platcs m', I fasten a spring-strip, m, made preferabl y of ham nered or hardened silver, which extends past the rodf, below the 'hookf', and into the path of the pins l'. The clampingblock m' is insulated from the clock-work j by the wooden case i, or otherwise, and an electric wire, n, is fastened to it by a contactscrew, n'. The wire u leads to an electric bell of the usual Construction.

ln the case iis a reel or spoo1,0, upon which astrip of paper, o' ,or similar material, is wound. The strip o' is led over a curved guide, p, and between two rolls, q q'. The rolls q q' are driven by the clock-work by means of suitable cogs or gearing, q and they draw the strip o' at uniform speed off ot' the spool c and over the guide 1).

Pivoted to a standard, a on the case z' is a lever, r, one arm ot' which extends between pinsf on the rodf, and the other arm extends in front of the guide p and is fitted with a pointed screw, r YVhen the red fis moved by the reversing-lever upon the reversal of the furnace it causes the lever r to turn on its standard r' and the point r to strike and puncture the strip o'.

The operation of my improvement is as follows: The time for reversing the furnace is indicated by the ringing of the bell, when one of the pins l' comes in contact with the spring on and closes the electric circuit. Then when the attendant reverses the furnace the movement of the lever a, swings the link c on its pivot d, drawing down the rod f. This causes the hook f' to come down on the spring m and draw it past the pin Z thereby opening the circuit and stoppiug the ringing of the bell. When the link c swings past the center and assunes the position indicated by broken lines in Fig. 2, which it obtains when the furnace is reversed, the rod frises and releases the spring m, which then resumes its normal position.

rotary and are operated by a shaft.

If it then comes in contact with the rear side of the pin l', it does not make electrical connection therewith, because it is faced at m with a non-conducting or insulating material. The longitudinal 'movement of the rod f also depresses one end of the lever r, and thereby causes the pin i" at the other end tostrike and puncture the strip o', andso register the movement of the reVersing-lever.

In Figs. 3 and 4 l show how my invention may be applied to several furnaces. Here there is one clock-work and bell for all the furnaces. In the case i there is a slidingrodfand lever r for each furnace. These rods and levers are arranged side by side. The strip 0' is made wide enough to eXtend across the path of all of the puncturing-pins of the levers 7'. Each rodfis provided with apin,f which projects over a bar, s, pivoted tc the side of the case z' atone end and extending over the spring m. When any one of the rodsfis drawn down by the action of the reversing-lever of its furnace it in turn draws down the bar s, which, acting on the spring m, opens the circnit in the manner described with relation to Figs. l and 2. The links c are each connected to their respective reversing-levers by a wire, t, which is held taut by a weighted or spring bell-crank lever, c In this way my invention may be applied to any desired number of furnaces.

I have spoken of the rex 'ersing-lever of a furnace; but I do not limit myself to a leVer, because in many cases the reversing-valves are By moving the pivoted link c by means of the valve mechanism the apparatus may be operated as described.

The utility of my invention consists in the facts that it indicates the time when the reversal should be made, and th us aids in obtaining regularity in' the working of the furnace or furnaces, and that it records the time and.

regularity of such reversal, and thus imposes a check upon the attendants.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. The reversing mechanism of a reversing furnace or furnaces,in combination with apivoted link or lever connected with and operated by said reversing mechanism, a sliding rod, the circnit-breaker of an electric signal-circuit, and registering device, said circuit-breaker and registering device being operated by said sliding rod, for the purpose of indicating and registering the reversals of the furnace, substantially as described.

2. In combination with the reversing meehanism of a reversing furnace or furnaees, a pivoted link or lever, a sliding rod Operating a contact spring or connection, a clockwork composing the terminal of an electric battery intermittentlyin contact with said spring, and an electrical bell, also in electrie contact with said spring, substantially as and for the purposes described.

3. In combination with the reversing meehanism of a reversing furnace or 'nrnaces, a pivoted lever or link, a sliding rod, a lever operated by said 'od and provided with a puncturing or registerin g point, a clock-work, and a strip or tape operated by said clockwork and movingin the rangeof said puncturing or registering point, substantially as and for the purposes described.

In testimonyewhereof I have hereunto set my hand this 25th day of May, A. D. 1882.

OGDEN BOLTON.
