IMPROVEMENT IN BREECH-LOADING FIRE-ARMS.

Specification forming part of Letters Patent No. 310,714, dated November 27, 1860.

To @ZZ whom it may concern.-

Be it known that I, JOHN BoYNToN, of the town of East Hartford, county of Hartford, and State of Connecticut,have invented new and useful Improvements in the Mode of Constructing Breech-Loading Fire-Arms; and I do hereby declare that the following is a corto the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the peculiar method of forming the breech part and attachments to a rifle or other nre-arm.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the drawings, Figure l is a longitudinal section of the breech part of the ride, showing the discharging arrangements as they appear when loaded and before being cocked. Fig. 2 is also a longitudinal section, as before, showing the appearance of the lever, &c., in the act of eocking. Fig. 3 is a view of the ball and stem, Fig. 4, a view of the detached breech and ball when charged for operation, Fig. 5, a transverse section of the breech.

The general construction of my rifle-barrel and the stock are in the customary manner. My improvements are as follows, viz At the breech end of the barrel A, in the part where the stock commences, I make a recess to contain the lock and the series f movements required for operating and discharging.

The lever B is constructed with a toothed rack and pinion, D, at the inner end, working on a center-pin, and matching into the teeth of the traveling ratchet O, to operate and actuate the same. This ratchet C forms the front or forward hammer land drives in the breech K and charge. The pinion D also works in the teeth of the lever or cover E, which is to cover up the space or opening formed to pass in the detached breech and charge K. Vhen the breech and charge are forced into their place, the lever B must be again pressed down, and it will then bring back the ratchet against the hammer F, which, being attached to the mainspring H, recoils till the notch in the back part passes over and onto the pin P, and thus forms the cocking arrangement.

The mainspring H is composed of acurved spring, attached at the back end to the fixed pin D, and at front end-to the pin in the lower part of the hammer F, and forms the triggerguard, as well as spring.

The detonating-pin I passes longitudinally through the center of the ratchet-hammer O and into` the center of the hammer F, to a hole, R, formed vertically in the same. It is the back part of this hole that strikes against the end of the detonating-pin I and drives it forward against the priming, to cause the eX- plosion of the charge. The trigger G is of simple construction, vibrating on a centerpin, and when pulled lifts up the hammer F from the pin l). The detonating-pin I is pointed at the forward end, to penetrate the primingy placed in or on the end of the stem M of the ball L, or some other similar device. In the end of the forward hammer, C, I form a recess to receive a packing, S. This packing is to ease the blow of the hammer against the end of the breech K when pressing inl the same, and also assists in the prevention of the escape of the gas when discharged.

The detached and adjustable breech K, I ymake of good, tough steel, in the form as described in the drawings, hollowed out to receive the charge of powder R and the ball L, with a touch-hole in the rear end for the priming. This breech K is about three-fourths of an inch in diameter, and fits in the bore of the barrel at the end of the lock-recess, with a beveled and tight joint, and is pressed home tight by the force of the hammer C, actuated by the lever B. Y

The ball L, I make witha wedge-shaped forward part and concave at the backend, to fit into the detached and adjustablebreech K. In the center of the same I insert orcast in a pin or stem, M, with a head on it to prevent its drawing out. This stem M extends .to the touch-hole at the end of the detached breech, and is hollowed out at the end to receive the priming for the detonating-pin I to strike against. The utility of this stem M is to balance the ball in its flight, and to cause the peint of the ball to be always in advance, thereby causing an increase of speed,power, and distance, (upon the principle of an arrow.)

The combined Aarrangement of all the parts combination, actua-ted by the lever B in the described forms a complete and substantial manner as herein described. breech-loading rifle, simple in construction and perfect in operation. JOHN BOYNTON' What I claim as my invention, and desire Vitness'es: to secure by Letters Patent, is- WM. VINE,

The rack C, pinion D, and limilispring H, in I T. A. STORRS.
