VILLIAM S. TEALL, OF LITTLE FALLS, NEW YORK.
rfiPE-QIPICATIQN forming part of Letters Patent No. 308,216, dated November 18, 1884.
Application filed August 16,1884. (N0 model.)
To all whom it may concern:
Be it known that I, WILLIAM S. TEALL, a citizen of the United States, residing at Little Falls, in the county of I-Ierkimer and State of New York, have invented a new and useful Improvement in Hammerless Guns, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to what are termed hammerless guns, or that class of breechloaders which employ a firing-pin to explode the cartridge in place of the usual hammer; and it has for its object to provide improved means which will be simple in construction, inexpensive to manufacture, and efiicient in operation.
A further object of the invention is to provide a gun of this class in which the operation of loading, firing, and extracting the cartridge can be easily performed without detracting from the accuracy of the aim, which will be light and convenient in every respect, and in which the motions of the hand necessary to manipulate the gun will be fewer and less complex than those required with breech-loading guns of this class.
WVith these and other objects in-view the said invention consists in certain details of construction and combination of parts, as hereinafter set forth, and particularly pointed out in the claims.
In the accompanying drawings, Figure 1 is a longitudinal sectional view of a portion of a breech-loading gun embodying my improvements, the stock and barrel being broken off and the breech-block closed. Fig. 2 is a sin1ilar view, the breech-block being thrown up to set the firing-pin, extract the cartridge, and load the barrel. Fig. 3 is a plan view of Fi 1, the breech-block being closed. Fig. 4 is a vertical section on the line at as, Fig. 5, the firing-pin and its actuating-lever being removed from their respective chambers. Fig. 5 is a transverse section on the line y y, Fig. 1. Fig. 6 is a detail perspective view of the firing-pin. Fig. 7 is a transverse section on the line a z, Fi 4. Fig. 8 is a detail side view of the trigger and its lever. Fig. 9 is a side view of the eccentric or cam and the firing-pin lever, illustrating the manner in which the cam acts to force the lever backward to set the firingpin.
Like letters refer to corresponding parts in the several figures.
Referring to the drawings, A designates the frame or breech-piece, having the stockO at one end and the barrel B at the other end, and recessed at D to receive the breech-block E. The latter has lugs F projecting upwardly from its upper face at the forward end, as shown in Fig. 3, and fitting over the breeclr piece against lugs G, which project from the same, the said lugs F G having their perforations registering with each other, to allow t1 e passage of the breech-pin H, which serves to pivot the breech-block and allow vertical movement thereof. The breech-pin passes through the breech-picce, as seen in Fig. 5, and is provided with a set-screw, a, which engages with one end thereof, so as to hold said pin from turning when the breech-block is thrown back. Upon the breech -pin H is mounted the extractor I, having its lower end notched to form afingcr, b, which engages with the cartridge, as seen clearly in Figs. 1 and 2, said extractor turning on the pin, and having its upper portion bifurcated or slotted at c, an eccentric or'cam, J, being rigidly held on the breech-pin by a set-screw, (Z, in the slot 0 of the extractor. (See Fig. 5.)
The breeclrblock is provided at its rear end with a knob or thu1nbpiece,K, and is interiorly recessed from the front end at the point where it comes in contact with the cartridge rearwardly, and in an upwardly-inclined direction, nearly to the thu1nb-knob, forming a chamber, L, for the reception of the firingpin M, and is further recessed from the point where it comes in contact with the eccentric rearwardly, on a slight downward inclination, until it joins with the chamber M to form a chamber, N, which provides room for the firing-pin lever 0. These chambers L N are each enlarged at c f, respectively, and are shown more clearly in Fig. 4, the chamber L having elongated slots 9 g in its opposite side walls to receive corresponding pins, 71, It, projecting outwardly from the sides of the firingpin, the latter being thereby guided in its movements and held from turning around. The said firing-pin M (seen in detail in Fig. 6) is round, so as to fit the chamber L, its front end, t, coming in contact with the cap of the cartridge, and having an enlargement, j, in
, under the action of its spring.
rear of said end, fitting within the enlarged portion 6 of the chamber, acoiled spring, I, encircling the central portion of the firingpin, one end of said spring bearing against the rear portion of the enlargement j, and the other end against the rear wall of the enlarged recess 6 of the chamber L. The upper face of the firing-pin at the rear end is formed with a downwardly-inclined slot, Q, into which the rear end of the firingpin lever O fits, said lever working in the chamber N, and having a collar, 1, thereon, a coiled spring, R, encircling the lever, and having one end bearing against the collar, and the other end against the rear wall of the. enlarged recess f of the chamber N. As seen, this collar 1 works in the said recess f to compress the spring, the latter serving to keep the front end of the lever always in contact with the eccentric or cam J. a
S designates the trigger-lever, pivoted in a recess, T, of the breech-block, and having its forward end provided with an upwardly-extending lug or projection, m, arranged to catch the firingpin at the front end of the enlargement j. as seen in Fig. 2, a spring, U, being secured to the breech-block, and having its free end bearing against the lever, so as to hold it in engagement. A trigger, V, is pivoted in a recess of the breech-piece, and is formed with a projection, 12, against which a spring, W, bears, said trigger having its upper end cam-shaped, as at Z, to engage with the pointed camshaped end is of the trigger-lever S, so that by the operation of the trigger the lever is disengaged or withdrawn from the firing-pin, to allow the latter to work forward A triggerguard, X, is attached to the piece in the usual manner and for the purpose well known. A spring-pressed pin or catch, Y, is fitted in the rear end of the breech-block, to engage with an indentation, 0, in the adjacent face of the breech-piece, said catch acting automatically to. engage and disengage itself with the said indentation.
The operation of my invention will be readily understood from the foregoing description, taken in connection with the annexed drawings. Supposing the parts to be in the position shown in Fig. 1, the cartridge having been exploded, the successive actions are as follows: Press the thumb piece or knob K upward until the spring-catch y is released from the indentation, allowing the breech-block to move upward in a forward direction, as seen in Fig. 2, the portion of the breech-block which comes in contact with the extractor I causing the latter to turn on the breech-pin, (see Fig. 2,) the finger b at the lower end engaging with the cap of the cartridge, and moving rearwardly to expel the latter in a rearward direction from the barrel. By reason of the hinging of the breech-block at its upper forward portion immediately in rear of the barrel to the breech-piece bya stud or breechpin on which the extractor is mounted the said breech-block will always be in position to tnrnthe extractor and effect the desired end. Now, as the breech-block is being carried forward and upward from slot in breechpiece at the same time that the extractor is operated, the firing-pin lever 0, Figs. 1, 2, and .9, bears against the eccentric or cam J, and is forced rearwardly by reason of the peculiar shape of said cam. When the limit of movement seen in Fig. 2 is reached, the firingpin lever has forced the firing pin back through its chamber L to the extreme end, the trigger-lever S catching around the front end of the enlargement j, thereby setting the fir ing-pin. The cartridge is then placed in the barrel and the breech-block closed down, the spring-catch Y acting automatically to yield inward, and then press outward to engage with the indentation 0 and hold the breechblock down in position. The trigger V bears at its cam-shaped end 1 against the pointed cam-shaped end 7c of the trigger-lever, so that by operating said trigger the front end of the lever is withdrawn from the firing-pin, causing the latter to act under the pressure of its spring P until its front end, 'i, comes in contact with the head or cap of the cartridge to explode the same in the usual manner, the parts being now in the position shown in Fig. 1.
It will be seen that the spring encircling the firing-pin lever 0 causes its outer or forward end to be always held against the eccentric or cam, so that when the breech-block is thrown up this contact of the lever with the eccentric or cam causes the gradual backward movement of the firing-pin until it is set. The pressure of the spring against the trigger-lever causes itto act automatically to retain the firing-pin set until released by the trigger. The spring'catch or pin Y engagesautomatically with the indentation 0 in the breechpiece, and by reason of the spring-pressure applied to the same said catch will be over come by the pressing of the breech-block upward. Since the breech-pin does not turn,the extractor should be mounted loosely on the same,so as to turn by the action of thebreechblock pressing against the same. By reason of the firing-pin lever 0 being always held in contact with the eccentric or cam J, the said lever will not be forced forward when the firing-pin is released to discharge the cartridge.
All parts of the mechanism are concealed within the breech block, so as to be free from accumulations of matter and protected from injury. The mechanism is simple in its construction, inexpensive to manufacture, efficient in operation, and will form a light and compact gun, which may be quickly loaded and fired, and is manipulated with ease.
Having described my invention, I claim- 1. In a hammerless gun, the combination, with the breech-piece, of the hinged breechblock, a spring-pressed firing-pin working in the latter, an actuating-lever arranged within the breech-block and held in engagement with the rear portion of the firing-pin, means, substantially as described, for forcing the actuating-lever backward, said means operating the lever automatically by the raising of the breech-bloek, and a trigger-lever to catch around the front end of the firing-pin when the latter is forced backward, as set forth.
