LEVER OPERATING D-EVICE. APPLICATION FILED JAN.4. 1911.
1,258,653. Patented Mar.12,1918.
In ran/m UNITED STATES PATENT OFFICE.
NEWELL H. CRAIG, OF SEATTLE, WASHINGTON.
LEVER-OPERATING DEVICE.
Application filed January 4,
To all 'lU/LO/it it may concern:
le it known that I, NuwnLL 11. Guns, a citizen of the United States, and a resident of Seattle, in the county of King and State it ll ashington, have invented certain new and useful Improvements in Lever-Operating Devices, of which the following is a full, true, and exact specification. i
My invention. relates to lever operating devices and has for its principal object to provide an improved and novel means for operating an electrical switch or pulling a bolt or catch at a pro-determined time. Another object is to provide means for adjusting the distance of movement of the lever operating device. Still a further object is to provide a novel arrangement of lovers which are adapted to contact with the alarm stem of the clock.
Other objects will appear as my invention is more fully explained in the following specification, illustrated in the accompanying drawing and pointed out in the appended claim.
In the drawings Figure 1 is a side eleva tion of my device with the clock omitted. Fig. 2 is a plan view of the same with the clock in place. Fig. 3 is an enlarged detail view 01 the operating parts. Fig. 4: is a de tail view of the cap plate.
Referring more particularly to the drawings, numeral 1 indicates a base to which entire device and clock are secured. 2 in dicates a tube inside of which is mounted a rod carrying tube 3 secured to a cap 4, which is tapped and through which a threaded rod 5 is screwed. Cap 4 is secured to tube 2, and has a coil spring 6 attached to it which extends around rod carrier tube 3, as shown. One end of spring 6 is attached near the forward end of rod 7, and its opposite end is secured to cap 1. Spring 6 is the power that throws rod 7 back against the stopping rod 5, stopping rod 5 being previously set to govern the distance of throw of rod 7 The outer end of rod 7 is provided with a thimble 8, which when set, engages a trigger 9, and comes into contact with a quarter cap 10.
A cord 11 is connected inside of sleeved head 8, and to any lever it is desirable to pull. When the rod 7 is released it pulls the cord 11, and operates the lever 12, opening or closing electric switches, acting as a time lock in connection with belts or catches, or stopping the alarm on the clock, as the Specification of Letters Patent.
1917. Serial No. 140,500.
case may be. As a means to retain and release the rod 7, I employ a trigger retaining lever 13, which is pivoted at one end, at 14. Lever 13 is provided with downwardly extending lugs 15, one of which engages a notch 16. in a locking lever 17. Locking lever 17 is pivoted at one end as at 18, and has a limit stop 19 beyond notch 16. The other end of lever 17 is to be turned in form of? a ring 20, which is adapted to engage the alarm stem 21 ot' the clock A spring 23 connects levers 13 and 17. and normally retained in the position shown. It will be noted that the free end of trigger 9 is normally beneath the outer end of lever 13, and is released only when lever 13 moves out of contact with the trigger. In operation the clock is set to alarm at the time desired to pull the switch. lVhen the alarm rings the stem 21 is slowly revolved and engages ring 20 with the result that lever 17 is shoved slightly to the right until the notch disengages from cooperation with one of the lugs 15. When the lug 15 is released the tension of spring 23 pulls lever to the left and releases trigger 9. The tension of spring 6 causes rod 7 to tip trigger 9 about its pivot point 24, thereby releasing the engagement of the head 8 and trigger 9 and allows the rod to move to the right and pull the cord 11.
It will be noticed that the tube 2, is made rectangular at its trigger end and is partially closed with a cap 10, and over this cap 10, is placed a cap plate 25 with an eye 26. The thimble S, abuts against the cap plate 25, and limits the forward movement of the rod 7 when pull is exerted on the cord 11, in setting the device. The rear end of the trigger 9 is located below the thimble 8 so that when setting the device the inner end of the tri ger will engage the rear end of the thimble and hold the spring under tension.
\Vhile I have shown a particular form of embodiment of my invention, I am aware that many minor changes therein will readily suggest themselves to others skilled in the art without departing from the spirit and scope of the invention, and I therefore desire to avoid being limited to the exact form shown and described.
Having described my invention, what I claim as new and desire to protect by Letters Patent, is:
In a device of the class described, the combination of a casing, a rod mounted to slide in the casino and provided at one end with a lug, a spring secured at one end to the rod and at its opposite end to the end of the casing, adjustable neans for regulating the movement of the rod in the casing, a pivoted latch at one end of the casinoadapted to engage behind the lug to hold the rod in extended position against the tension of the spring a pivoted latch holding lever provided at one end With an extension and an intermediate projection, said latch holding lever adapted when set to enga 'e the free end of the latch to hold the latter in en gagement With the lug, a pivoted releasing lever having a notch in one edge with which the intermediate projection engages to lock the levers in operative position, a spring connecting the intermediate at the end of the latch holding lever and the releasing lever, a connection extending from the free end of the rod to a device to be operated, the free end of the releasing lever being adapted to be moved by time operating means to disengage the notch from its c0operating projection and permit the spring between the two levers to actuate the latch holding lever and release the latch.
