IMPROVEMENT IN ESOAPEMENTS FOR TIME-PIECES.

TO ALL WHOM IT MAY CONCERN Be it known that l, HERMAN REINECHE, of the city, county, and State of New York, have invented a new and improved Escapcment for Time-Pieces; and I do hereby declare that the following is a full, clear, and. exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a sectional front elevation of this invention,

Figure 2 is a side elevation of the same.

Qimilar letters of. reference indicate like parts.

This invention relates to a mechanism which combines the advantages of the detached escapement with the lever escapcment, the balance being so arranged that it receives an impulse from the escape-wheel, while it swings in one direction only, being perfectly free from the power of the main-spring during the other halt of its motion, and the impulse produced by the escape-wheel is transmit-ted to the balance by means of a lever.

- A represents the escape-wheel, and B the balance, which is mounted on the arbor or staff a. The-escapewheel has a tendency to revolrc, under the action of the main-spring, in the direction of the arrow marked thereon in fig. 1, and its teeth act on the pallets p, which project from a bar mounted on the arbor b, the palletp being so sha ed that the same fits between two succeeding teeth of the escape-wheel, and that when the arbor his turned in the direction of the arrow marked near it in fig. 1, so as to raise the pallet 11, the joint of the tooth of the escape-wheel glides down over. the inclined face of said pallet, and as the tooth leaves the pallet 10, the next preceding tooth strikes the pallet 10, and causes the pallet to drop again between the teeth to the position in' which it is shown in fig. 1. The oscillating motion of the arbor 6 is produced by the action of a pin, a, which projects from the hub of the balance; and which acts on a lever, C, that is mounted on the arbor 6. From the end of this lever project two pins, (Z a, and a liftiug-spring,f, bears against the pin e. The

.pin (2 acts ona piu,g, projecting from the hub of the balance, and serves to impart to said balance the required impulses. If the balanceswings in the direction of the arrow, marked on it in fig. 1, the pin 0 passes the liftingspring f without producing any motion of the lever C, and the pallets are not disengaged from tho escape-wheel; but if the balance returns in the direction opposite the arrow marked on it, the pin 0, on coming in contact with the lifting-spring, causes the lever C and arbor Z) to turn in the direction of the arrow marked near it in fig. 1, and the palletp rises, allowing the tooth of the escape-wheel to slide down on'its inclined edge. As soon as the tooth strikes the inclinededge of the pallet, the pin (Z is thrown in contact, with the pin 9, in the hub of the balance, and an impulse is given to said balance sufiicient to keep up its motion. When the pin a has passed the lifting-spring, the lever C returns to its original position by the actionof the escape-wheel on the palletp, and the balance, in swinging in the direction of the arrow marked on it in fig. 1,. is relieved entirely of the force of the main-spring, and it has to overcome no obstruction besides the friction, the resistance of the air, and that of the liftiIzg-spring. By thishrrangemcnt an escapement is obtained in which the impulses imparted to the balance are as near as possible uniform, and furthermore, during a large part ofits motion, the balance is entirely relieved of the power of the main-spring, and its oscillations become isochronim My eseapement'is applicable, with equal advantage, to a horizontal or to a verticai balance, and itcan be used for clockmovements as well as for watches.

What I claim as new, and desire to secure by Letters Patent, isp Thepallctsp 31, mounted on the oscillating arbor b, in combination with the lever G, lifting-springf, pins d e g c, and balance B, all constructed and operating substantially as and for the purpose described.

HERMAN REINECKE.
