Specification of Letters Patent.

Patented Jan. .14, 1908.

Application filed June 2i). 1906- Serial No. 322,559.

T 0 all whom it may concern: e Be it known that I, ROBERT A. WOOD, a citizen of the United States, and a resident of the city of New York, borough of the Bronx, in the county and State of New York, have invented a new and Improved Recorder, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved recorder, more especially des' ned for use on rolling mills and other mac es, and arra ed. to accurately record the amount of materlal fed through the machine by the workmen and the time, thus giving a full and complete record of the operators work during working hours.

The invention consists of novel features of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in allthe views.

Figure 1 is a front elevation of the imrovement as applied to a rolli mill, the atter being shown in dotted lines; Fig. 2 is an enlar ed front elevation of the improvement; Flg. 3 is a plan view of the same, and Fig. 4 is a side elevation of the improvement as arranged for recording the work done by two mac ines.

The improved recorder is mounted on a suitablebase A, preferably attached to the framework B ofthe roll' mill B or other machine on which the recorder is to be used. On the base A is erected a standard A .on which is mounted to rotate the carrier O carrying the indicator card D removabl held on one face of the said carrier C by t e use of suitable clamps E or the like holding devices. The rolling mill or other machine is driven at a constant or uniform speed, thus allowing the indicator card to be graduated to represent hours. As shown in the drawings the indicator card D is divided into equal sectors D each representing an hour, so that the face of the indicator card is divided, sa into ten sectors representing ten Working ours of the day. The face of the indicator card D is also divided by concentric circles into annular bands D representing the working days of the week, as will be readily understood by reference to Fig. 2.

The card carrier O is preferably in the form of a wheel, provided on its peripheral face with a worm wheel O in mesh with a worm F secured on the upper end of a shaft F j ournaled in suitable bearings arranged on the standard A. On the lower end of the shaft F is secured a worm wheel F in mesh with a worm F secured on a shaft F arrangedhorizontally and journaled in suitable bea s on the base A. On the shaft F 'is secure a pulley F connected by a belt F with one of the rolls of the rolling mill B; for instance, as shown in Fi 1, the roll B, be-

tween'which and the'rol B passes the material to be treated by the rolling mill. Now,

when the rolling mill is driven a rotary motion is transmitted by the gearing described to the carrier C, to give to the latter a complete revolution during the ten hoursof a wor day, it being understood that the aforesaid gearing is proportioned correspondingly. 1

On the face of the indicator card D is indicated a stylus G, in the form of a pencil or the like, held in a sleeve G mounted to slide in a suitable bearing H, having a pin H mounted to turn in a bearing A secured on the base A, to allow of turnmg the bearing H to bring the stylus G in the corres onding week indicated on the face of the in cator card D. When the desired proper relation to adjustment has been made the bearing H is secured in place by a set screw H screwing in the bearing A against the pin H"(see Fig. 4). The stylus G is normally held out of engagement with the face of the indicator card D and for this purpose a spring G is employed and coiled on the sleeve G, one end of the spring abutting against the bearing H and the other end resting against a shoulder G formed on theouter end of the sleeve G. An eye G having a segmental slot extends from the outer end of the sleeve G and is engaged by the arm I of a bell crank I fulcrumed at I on the base A. The other arm I of the bell crank lever I is engaged by an arm J secured on a rock shaft J mounted to turn in a bearing K, preferably attached to the framework B of the rolling mill. On the rock shaft J is secured a second arm J extending into the path of the work passing between the rolls B and B of the rolling mill, the said arm being for this purpose preferably located in the rear. of the said rolls B and B as plainly indicated in Fig. 1. Now,

B it engages the arm J and imparts a swingwhen the work passes between the rolls B A mg motion to the same, so that the shaft J is rocked and its arm J imparts a swinging motion to the bell crank lever I to push the sleeve G and its stylus G'inward against the tension of the spring G Now, this inward movement of the stylus brings the point thereof in contact with the face of the indicator card D at a proper hour and day, so

' passes between the rolls B -by the action of the spring G that the stylus traces a line on the rotating card 1), thus indicating the length of time the work passed through the rolls B and B It is understood that the arm J is held in the position referred to as long as the work and B, and as soon as the work ceases to pass between the rolls B and B then the stylus G is released and returned to its normal inactive position Now, when the stylus G returns to its normal inactive position the bell crank lever I and the arms J and J are returned to their normal position, so that the arm J is again in position to be engaged by the work next passed through the'rolls B and B of the rolling mill.

From the foregoing it will be seen that the recorder readily and accurately indicates the time the machine was running idle and also the time the machine was doing work, and hence a full record of the doings of the operator is had.

If desired, the indicator cards may be arranged on both sides of the carrier C, and in this case an additional stylus, bell crank lever I and mechanism for operating the same as shown and described is added to the machine, as will be readily understood by reference to Fig. 4. Thus one recorder is used for recording the work done by two machines.

The recorder shown and described is very simple and durable in construction, is comosed of comparatively few parts and not 'able to easil get out of order.

Although have shown a preferred form it is evident that I do not limit myself to the detail construction shown and described, as the same may be varied without deviating from the spirit of my invention.

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

1. A recorder'for attachment to rolling mills and other machines, comprisinga revoluble card carrier driven from the machine and ca'rrymg an indicator card, a stylus for the said card and normally held out of contact with the same,'- and mechanism formovin the said stylus into contact with the sai card, and having'o eratin means projecting mto the path of t e wor passing through the machine.

2. A recorder forv attachment to rolling mills and other machines, comprising arevoluble card carrier driven from the machine and carrying an indicator card, a stylus for the said card and normally held out of contact with the same by the action of a spring, a bell crank lever engaging the said stylus, and a rock shafthaving arms, one engaging the said bell crank lever and the other projecting into the path of the work passing through the machine.
