SPRING GUN. No. 403,432. Patented May 14.11889.

SPRING-GUN.

SPECIFICATION forming' part 0f Letters Patent NO. 403,432, dated May 14, 1889. Application filed November 10, 1888. Serial No. 290,485. (No model.)

To all whom, t may concern:

Be it known that I, EDWARD Y. KNAPP, of Blue Lake, Humboldt county, State of California, have invented an Improvement in Guns; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to the mechanism and construction of a toy gun.

It consists of a barrel, a magazine, a vertically-moving carrier by which the bolts or darts are transferred from the magazine to the barrel, and a mechanism whereby the carrier is lifted in the act of cocking the gun and is retracted when the trigger is pulled, leaving the bolt to be struck by the hammer and ejected from the gun-barrel.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure l is a view of the gun, showing the hammer down. Fig. 2 shows the hammer drawn back and the carrier lifted so as to hold the bolt in line with the barrel. Fig. 3 is a view of the breech-block. Fig. 4 is a view of the carrying-slide.

A is the barrel of the gun.

B is the magazine in which the bolts or darts are placed, and Cis the stock of the gun.

C is the breech-plate, the upper part of which iits the rear end of the barrel and magazine, and it has extensions c downward upon each side. The lower ends of these extensions are bored to fit upon the same bolt upon which the tumbler turns. The rear of the breech-plate has a slot made in it in line with the rear of the barrel, and through this slot the long iiring-point of the hammer passes to discharge the projectile.

Behind the barrel and magazine is a vertically-moving' slide, D, having its upper end so formed that a single bolt, E, from the magazine will slide upon it when the muzzle of the gun is held upward. The lower end of the slide .D has a toothed rack, F, formed upon its rear edge, as shown.

G is the hammer, having' the circular tumbler H, a part of the periphery of which has teeth I formed upon it, so as to engage with the teeth of the rack F, raising the rack and the slide D, thus lifting the bolt E to a point opposite and in line with the interior of the barrel A.

K is the spring, which acts both upon the hammer and upon the trigger L,which is pivoted in the lower part of the stock, the point or sear of which engages the notch M upon the tumbler when the hammer is drawn back, as shown in Fig. 2. Vhen in this position, it will be seen that the bolt E is held in line with the barrel A, and when the hammer is released by pulling the trigger .L it is thrown forward with great velocity by the action of the spring K. The teeth I, engagingthe teeth F of the rack, draw the slide D down with such velocity as to leave the bolt in position to be struck by the point of the falling hammer G with such force as to eject it to a considerable distance from the gun. Another bolt E is brought into position to be loaded into the gun by simply holding the muzzle of the gun upward, and the operation may be continued until all the charges are out of the magazine.

The projectiles may have a disk containing percussion or fulminate powder fixed to the rear ends, so that the blow of the falling hammer will explode the fulminate at the instant when the impulse is given to the projectile.

The front edge of the tube which supports the projectile has an upwardly-projecting lip which serves to separate the projectile which is in position to be raised from those remaining in the magazine. It also prevents the proj ectile from sliding out through the barrel if the muzzle be depressed. I

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The parallel barrel and magazine of the gun, the vertically-moving carrierD, having a ixed breech-plate common to both with an aperture in the upper part, in combination with a hammer, the striking part of which enters the aperture, said hammer having the circular tumbler formed upon its lower end and provided with teeth which engage the rack F on the lower rear edge of the carrier, the trigger L, and the spring K, substantially as herein described.

2. The perforated breech-plate C', with the extensions c, fitting the tumbler shaft, the hammer with the elongated strikingpoint which passes through the slot in the breechplate, and the vertically-moving carrier raised IOO and lowered by said hammer and by which the projectile is raised and held so as to be struck by the falling hammer, substantially as herein described.

.3. The parallel barrel and magazine, the xed breech-plate common to both and having its upper part slotted or perforated, in-

combination With a spring-actuated hammer having a point adapted to pass through the aperture in the breech-plate, and a carrier actuated in conjunction with Ihe hammer to raise a proj eetile from the magazine to a point opposite the barrel,where it is struck and impelled by the falling hammer, substantially as herein described.

In Witness whereof I haVe hereunto set my hand.-

EDWARD Y.l KNAPP.
