APPARATUS ACTUATED BY CLOCK-MOVEMENTS FOR STARTING R STOPPING MACHINERY.

srncrrrcnrron forming W of Letters Patent No.7o2,es2, dated June 17, 1902.

Application filed February 12, 1902. Serial No. 93,665. (No model.)

To (tZZ whom it may concern.-

Be it known that I, JOHN SAMUEL SUNDER- LAND, electrotyper, a subject of the King of Great Britain, residing at 37 Aberdeen road,

Highbury, London, England, have invented certain new and useful Improvements in'Aplever, or other suitable mechanism, start or stop any machinery employed for electrical,

chemical, hydraulic, mining, milling, electroplating, or other purposes.

s In order that my invention may be more clearly understood and readily carried into eifect, I will proceed to describe the same more fully in connection with the accompanying drawings, in which 3 Figure 1 shows the apparatus before the release of the starting or stopping device, and

0 Fig. 2 shows the apparatus after the release of the said device. Fig. 3 is a front elevation, and Fig. 4, is a plan, both on an enlarged scale, of the clock-movement with the dial removed. Fig. 5 is a diagram showing the 3 5 device adapted to stop a power washing-machine at a prearrangedtime.

Ct is the face of a clock, provided with a spring I) and with a supplementary dial 0 and indicator or hand at for determining at what hour the spring I) shall be released in the same manner as in an ordinary well-known alarmclock.

e is a pawl pivoted to the clock-case and having an arm fiwhich bears upon the spring 6. g is a weak spring for holding the arm fin contact with the spring b. The tooth h of the pawl e is adapted when the spring I) is wound up to engage with a hook or tOOlJlLY;

. on an arm 7', carried by a rod 7a,.adapted to' slide longitudinally in guides Z Z.

m is a spring which tends to move the rod 70 away from the pawl e.

Referring to Figs.3 and 4, the spring bhas one end fixed to theclock case or frame and the other connected to a spindle b, which also'carries a handle b for winding up said spring. The spindle b also carries a ratchetwheel 19 connected by a spring-pawl b, to a toothed wheel 0, loosely mounted on the spindle b" and connected by a gear-train'p q r to an escapement -wheel 3. The e'scapementwheel .9 is normally held stationary by a tooth or pawl. 25', carried by a rocking shaft o, which also carries an arm 1). wis a spring fixed at one endto the frame of the clock and having its opposite end bent and adapted to be moved The tending to hold an incline an on the wheel a;

in contact with a pin d carried by the spindle d. d is a handle for turning the indicator w and simultaneously moving the pin (1 to the required point on the incline w to insure that the escapement-wheel s is released andthe spring I) permitted to expand at the proper-time. The toothed wheel 00 is connected by gear-wheels 00 00 m to the clockmovement operated, as is well understood, by the mainspring y and an escapement z.

When the spring 6 is wound up and the indicator (1 set to the required time, the free end'of the springw is held-in the path of the arm why the pin (1 bearing upon the incline 0c. The clock-movement gradually rotates the wheel a, while th'epind remains stationary until a shoulder in which said incline terminates, reaches said pin. The

spring to is then'pe'rmitted to move the wheel 00 along the spindle (1 until the pin d reaches the lowest point of the incline as. This movement of the spring to is sufficient to release the arm n and escapement-wheel .9, thereby permitting the spring I) to expand and operate the pawl a. When the spindle d is rotated to again set the indicator d, the pin d by moving along theincline a againmoves spring 10 into the path ofthe arm 11;

As shown in Fig; 1, the spring b is wound up and the hook t' is'in engagement with the tooth h, thereby holding the rod 70 toward the left against the resistance of the spring 711.

In Fig. 2 the springb has just been released and the spring I) by expanding has raised the tooth h of the pawl eout of engagement with the hook t on the army, thereby releasing the rod 70 and permitting the spring m to move said rod toward the right for starting or for stopping any required apparatus. The rod is may be connected in any appropriate manner to the starting or stopping device of the required apparatus.

To reset the starting or stopping apparatus,

the indicator (Z is moved so as to point to the required start-ing or stopping time and the spring I) is wound up, as is well understood. The rod 7.: is then moved by the knob or finger-piece n and against the resistance of the spring m until the hook 2' engages with the tooth h.

Referring to Fig. 5, 1 is the washing-machine, adapted to be actuated by band-andpulley gear from a rotary shaft 2, driven from any suitable source of power. 3 is a fixed pulley on the shaft 2, and 4 is a pulley running loose upon said shaft. 5 and 6 are respectively fixed and loose pulleys upon a shaft 7, geared by toothed wheels 8 with the washing-machine 1. 9 is a rod adapted to slide in the direction of its length and supported in bearings 10 10. The rod 9 carries a loop 11, embracing the band 12, and is pivoted at 13 to an arm 14, pivoted at one end to a fixed point 15. The end of the rod 71: is connected to the arm 14.

As shown in Fig. 5, the hook t is engaged by the tooth h of the pawl e, and the spring I) is wound up. When the clock-movement re; leases the spring b, as above described, the rod 70 is liberated and pushes the arm 14 and rod 9 in the direction of the arrow, thereby shifting the band 12 from the fixed pulleys 3 5 onto the loose pulleys 6 8, as shown in dotted line, and permitting the machine 1 to stop.

\Vhat I claim, and desire to secure by Letters Patent of the United States, is-

1. In a mechanical starting or stopping device, the combination with a clock-movement, a spring, means for putting said spring under tension, means operated by the clock-movement for releasing said spring at a prearranged time, a starting or stopping rod, a spring arranged to act on said rod,and aspring acting on said releasing means to normally hold the same in engagement with the rod.

2. In a mechanical starting or stopping device, the combination of a clock-movement, a spring, means for putting said spring under tension, a pivoted member arranged to be engaged directly by the spring as it unwinds, a starting or stopping rod, a hooked arm carried thereby, interengaging means between said arm and pivoted member, and means acting on said member to normally hold said interengaging means in locked position.

3. In a mechanical starting and stopping de* vice, the combination of a clock-movement, a spring, means for putting said spring under tension, an escapement-wheel, a gear-train connecting said escapement-wheel with the spring, means for normally holding said escapementwheel stationary, a pivoted pawl which bears upon the spring, a starting or stopping rod, a spring which tends to move said rod away from the pawl, a hook carried by the rod and adapted to engage with the pawl when the spring is under tension and thereby hold the rod against the resistance of its spring, and means operated by the clockmovement for releasing the escapement-wheel at a prearranged time substantially as described.

In testimony whereof I have hereunto set my hand, in presence of two subscribing witnesses, this 28th day of January, 1902.

JOHN SAMUEL SUNDERLAND.
