REGISTERING DEVICE.

HPECIFECATION forming part of Letters Patent No. 342,388, dated May 25, 1886.

Application tiled September i, 1855. Serial No. 176,155.

To (tZZ whom it may concern.-

Be it known that LL. LEwIs SAGENDORPH, of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Registering Devices, of which the following is a specification.

My device is an index to be attached to an engine or machine to indicate the number of revolutions or complete movements made by the machine.

In the accompanying drawings, Figure l is a rear elevation of my device. Fig. 2 is an elevation as seen from the 1eft-hand side of Fig. 1. Fig. 3 is an elevation of the operatingratebct with attached mechanism. Fig. 4 is a front elevation of the indicatouface. Fig. 5 illustrates particularly the functions of the adj ustable'arm H.

Two standards, A, mounted on a suitable base-plate, support the mechanism. These standards are cut away and grooved to receive thejournal-blocks B. The shaft B is journaled in the blocks B, and projects beyond each standard A. A toothed wheel, 0, pref erably of considerable width, is shrunk onto the shaft B, or otherwise rigidly attached there to. 011 each side of the wheel 0 is a bar, E, one of which bars may be dispensed with; but the arrangement shown is preferred. These bars E are slipped onto the shaft B and retate loosely thereon. Blocks E are placed between the corresponding ends of these bars E to keep them far enough apart to prevent fric- 3 5 tion against the wheel 0.

Screws or bolts S pass through the bars E and blocks E binding them together, and make a frame which rotates or oscillates on the shaft I3 about the wheel G. The pawl P,

mounted on the shaft P, (see Fig. 3,) engages the teeth of the wheel 0, and is kept against these teeth by the spring K. The preferred attachment of the spring K to the shaft P is very simple and efiicient. A slit, P is made across the end of the shaft 1? at right angles to the line of the pawl 1 In this slit P the straight spring K is secured, and it is then bent around over the pin or lug P. This gives it the required tension.

The bar E is attached to lower ends of the chine.

(No model.)

bars E,and its lower end being placed between them takes the place of or may be connected to a rigid extension of the lower block E. A bar, H, passes through the end of the bar E, and is seen red there by the set-screw S for the purpose of setting the rod H and regulating the rapidity of the rotation of the dial-plate, and the number of notches the wheel 0 is rotated at each throw or movement of the ma- A spring, V, is attached to the lower end of the bar E, and also to some other convenient point. It acts to draw the pawl I? back, as shown in Fig. 1.

\Vhere journal-boxes O are present, each standard A is respectively provided with a separate cap. B placed across the top of each standard, and the screws S secure their respective caps B to their respective standards. Through each cap B a bolt, S, passes and bears againstthebearing-block,\vl1ich it serves to keep in place. Vhen desircd,the journalboxes B may be dispensed with, and thejour nals of shaft B work in openings in the solid plate.

At the rear of the device is a frictionclutch, G. This clutch is preferably made of a single piece of metal split through nearly its entire length, and provided with enlargements and openings to accommodate the screw S and the end of the shaft B. The clutch is firmly attached to the standard A by the screw S a washer, w, intervening. It then clasps the shaft B and the amount of pressure or friction which it exerts on the said shaft in opposition to the rotation of said shaft is regulated by the screw S The indicator disk or plateD is centered on the front end of the shaft '13, and rigidly secured thereto, so that it may turn with the shaft.

An indicator or index hand or pointer, I, is attached to the base-plate M, or other fixed part of the machine, and projects in front of the disk D. This pointer indicates the amount of movement of the disk I).

The mode of operation is very simple and almost apparent from the device itself. The device is attached to the engine or machine, so that some part of the moving machinery, preferably a pin on a wheel, may strike the IOC arm H. When the rod His struck, it brings the bars E E into the position shown in Fig.

, 3. With this movementthe pawl P turns the bythe indicator I on the disk D. When a single disk D is insufficient to represent the desired revolutions of the machine, this disk may be geared with a series of disks in the usual or any desired manner, either on its periphery or on the shaft, so that the various disks may represent units, tens, hundreds, 850.

The advantages of the adjustability of the arm II will be apparent from Fig. 5,where the arm H is shown in connection with a cam or rotary movement on the machine. N indicates a cam or disk fixed to a shaft rotating in stationary bearings. A lug, W, is fixed on the disk or cam, or,when the disk or cam rotates in a strap or yoke, the lug W may be.

affixed to said strap or yoke. Each rotation of the cam causes lug \V to move the arm H forward and the registering-disk to be rotated, the arm being then immediately drawn back into position to be again moved by the lug W.

While the arm H occupies the position shown in solid lines in Fig. 5, the lug W will cause arm H to rotate the disk one digit. If, now,the armH be lowered and reset by means of setscrew S in the position shown in dotted lines in Fig. 5, the lug \/V will move the arm H fart-her, and cause the pawl P to skip a greater number of teeth of the wheel 0, and

cause the disk D to be rotated more than one digit. In this manner the number of digits to be registered at each movement of the machine can be regulated. In some classes of machines it may require some intermediate mechanism to specially adapt this arm H to the machinery to be registered, and in some instances it may be desirable to dispense with arm H and allow the arm or piece E to be moved directly by the machine whose movements are to be registered.

WVhile the various features of my invention 5 are preferably used together, one or more may be used without the remainder, and, in so far as applicable, in connection with registering devices other than the one herein specifically set forth. 6o

\Vhat I claim as new and of my invention, and desire to secure by Letters Patent, is

1. The combination of shaft B, wheel 0, bar E, pawl P, standard A, and split frictionclutch G, provided with clamping-screw S substantially as and for the purposes specified.

2. The combination of standard A,shaft B, toothed wheel 0, bars E, pawl P, spring K, bar E, and split friction-clutch G, provided with the clamping-screw S substantially as and for the purposes specified.

8. The combination of standards A, provided with bearing-blocks B, shaft B, toothed wheel 0, bars E, pawl P, spring K, bar's E, spring V, clutch G, disk D, and indicator I, substantially as and for the purposes specified.

4. The combination of shaft B, wheel 0, pawl P, bar E, shaft P, provided with slit P, and spring K, one of whose ends is located in said slit P, pin or lug P against which the spring bears and by which it is put in tension, substantially as and for the purposes specified.
