REGISTER AND AUTOMATIC STOP.

SPECIFICATION forming part of Letters Patent No. 410,242, dated September 3, 1889.

Application filed February 11, 1889. $erial No. 299,550. (No model.)-

T aZZ whom it may concern.-

Be it known that I, CHARLES J. HARTLEY, of the city of Decatur, county of Macon, and State of Illinois, have invented a certain new and useful Register and Automatic Stop, of

which the following is a specification.

My invention is particularly designed to register the number of operations of grainweighers and automatically stop the same at the completion of any predetermined number of discharges; but other analogous uses are readily apparent.

In the drawings accompanying and forming a part of this specification, Figure 1 is a face I 5 view of my device. Fig. 2 is a rear view with the rear plate and stop mechanism detached. Fig. 3 is a rear elevation of the complete device, and Fig. 4 is aside elevation of the same.

The face of the casing to has the graduated dials Z1 and c, the one indicating multiples of the other. Hands d and d are pivoted at the centers of dials b and 0, respectively. They are mounted, the one on a pin projecting through the casing from the center of the gear-wheel e and the other on a pin projecting from ratchet-wheel f. Pinion g meshes with wheel 6. -A long tooth g on wheel f advances the pinion one tooth at each rotation of the wheel, and wheel e is correspondingly go advanced. Arm k is actuated by the device the movements of which it is desired to register, connection being made therewith from the perforation n. Pawl Z is pivoted on the arm and held in contact with wheel f by spring 5 on. By the use of the pawl the oscillatorymotion of the arm is transferred to the wheel as intermittent rotary motion. Clicks 1' and h prevent back motion in wheels 6 and f. The wheels have bosses e and f and threaded pins 6 and f. Circular disks 8 and 'u. are mounted loosely on pins 6 and f", respectively, and are held in close contact with the bosses, when desired, by set nuts t and c.

The disks 3 and a are graduated and numbered the same as their corresponding dials h and 0, except that the direction of progression is opposite and they have the peripheral notches 8 and a. Bar 20 has longitudinal motion in brackets q and z, and it tends to move downward through the influence of gravity and the pressure of spring ,2". Arm

w is secured to the bar in a manner permitting adjustment and has a catch adapted to notch 8. Arm w is also adjustable on the bar and has a catch adapted to notch a. Lever 0 pivots on lug p and has the crank-extension 0', which is slotted at 0 to receive pin x of bar to. The arms 10 and 10 rest ordinarily on the disks and hold the head 10 ofbarwsome distanceabovebracketq. Lock- 6o arm 0", when swung under head 20', as shown in Fig. 4, renders the stop mechanism inoperative. At y is shown an end of a trip-lever, which rests on the end of lever 0 and connects with the weigher or other mechanism in such manner as to stop the same when unsustained. \Vheel f and pawl Z are in one plane. Tooth g, pinion and wheel (2 are in a slightly-different plane, so that the pawl will not be effected by the long tooth. The small diameter of the pinion enables the long tooth to mesh readily with the teeth of the pinion, and by the use of the pinion the wheels are rotated in the same direction. As arm 7.; is actuated wheel f is advanced tooth by tooth and hand d pointby point until a complete rotation of the wheel f is elfected, when tooth g willhavc advanced the wheel e one tooth and the hand (l one point. The unit of rotation of hand cl with the graduation, as shown, is forty, and so So the divisions of dial 7) represent multiples of that number. It is obvious,- however, that by changing the wheels and graduations the unit of rotation may be varied.

In Fig. 3 the device is shown as set to stop on the completion of four hundred and twenty movements, and the catch of arm w is over the number 400 on disk .9, while the catch of arm 10 is over thenumber BOondisk u. The disks are numbered backward and move backward, so that when four hundred movements have been made notch s, which is at zero, will be under the catch of arm to, and when twenty additional movements have been made notch u will be under the catch of arm 10'. This coincidence permits the bar to descend, swinging the end of lever 0 clear of the triplever y, and so effecting a stop.

To set the device so as to stop upon the completion of acertain number of operations, which number may be represented on disk 3, arm to is raised sufliciently high to be inop erative, and, the disk 5 is set with the desired number under the catch of arm w;

The stop is adjusted'by loosening the setnuts t and o, turning the disks 8 and u to the numbers that the register is to stop at, and then tightening the nuts tand o, so as to hold the disks 5 and u firmly on their sleeves.

I elaim 1. A stop for registers comprising the gradu ated and numbered dials, the disks rotatingly adjustable on the dials, numbered to correspond with the dials, but in the reverse direction, and having peripheral notches at the zero-points, and a longitudinally-movable bar having catches adapted to the notches and resting ordinarily on the peripheries of the disks, as set forth.

2. A stop for registers comprising the gradu 1 a'ted and numbered dials, the disks rotatingly adjustable on the dials, numbered to correto drawthe bar downward, and lever 0 0, connected with the bar, as set forth.

In testimony whereof I sign my name in the presence of two subscribing Witnesses.

CHARLES J. HARTLEY.
