T 0 all whom it may concern:

Be it known that 1, EMIL A. BARTEZKI, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Shooting Apparatus, of which the following is a specification.

This invention relates to shooting apparatus, and pertains more specifically to a means for testing the skill of the operator in shooting discs of metal or other suitable material, and comprises a housing or support containing a target, and having associated therewith a suitable gun adapted to be manipulated for sighting and for shooting the discs toward the target.

The aforesaid means are believed to be not only combinately novel, but certain of the devices goingto make up such means are new in less combinations than the whole, and some capable of individual use as will more clearly hereinafter appear. Various objects and advantages will be apparent as the description proceeds.

In the accompanying drawings forming part of this specification, in which {like numbers of reference denotes like parts wherever they occur,

V Figure 8 is an enlargement fragmentary horizontal sectional view of a modification, taken on the line 88 of Figure 9; and

Figure 9 is an enlargement fragmentary vertical sectional view of the same on the line 9-9 of Figure 8.

A housing 1 has its floor 2 and rear wall 3 constructed preferably of wood or other substantial material. The lower portions of when the side walls 41 and 5 and the front wall 6 are likewise preferably constructed of the same material, while the upper portions of these walls and the top 7 of the easel are constructed of glass or other suitable transparent material, preferably formed of plates 7, 8, 9, and 10 cemented or otherwise suitably fastened together, and secured in grooves 11 formed in the wooden portions of the structure 1.

V An aperture 12 is formed in the front wall 6just beneath glass plate 10,'the said aperture being of such size that a barrel 13 of a gunl may be loosely inserted therein so that the said gun may be shifted to permit of sighting the same into alinement with a target 15 on the inside of the rear wall 3. The aperture or opening 12 is terminated at its top by the bottom edge 16 of the glass plate 10, the wooden portions above the top of the aperture being removed to provide an unobstructed view through the glass for the purpose of sighting along the sights 17 and 18 located along the top of the gun barrel 13 inside and outside of the housing 1, respectively. The slot or elongation 19 of the upper end of the aperture 12, thus formed by removing the wooden portions, preferably converges to a constricted mouth at the top edge 20 of the wooden front wall 6, as best shown in Figure 1. v

Projections 21 and 22, separated by an intervening slot or notch 23, depend from the underside of the barrel 13. A plate 24, se-

cured by screws 25 to the outside of the front wall 6, reinforces the wooden marginal edges 26 of the aperture 12, the said plate being substantially of horse-shoe shape and having its inner marginal edge 27 in registration with the marginal edges 26. The lower portion of plate 24: passes through notch 23, thereby holding the gun' 1 1 within predetermined limits and preventing its withdrawalfrom the aperture 12 unless the plate 24; is first removed by unscrewing the screws 25. Wall 6 is recessed at 28'to allow room for projection 22.

The gun is preferably formed of suitable cast metal, being cast in two sections 29 and 30, meeting in the central longitudinal vertical plane through the gun, and joined together by screws 31. A projectile-directing passage 32 is formed in the barrel 13, pref erably in section 30, the said passage having a cross-section similar in shape and very slightly larger than the greatest diameter of a disc or; slug of metal or a coin 33.; shown in dotted lines in Figures 2, 3, and 9. In use, the gun is inclined slightly, so that its forward end is higher than its near or handle end, whereby the disc-shaped projectile 33 is permitted to run down the inclined passage until it rests against av shoulder or seat 34, formed by constricting the passage at its inner end.

A short distance ahead of the shoulder 34 is aplate 35, fitting in a recess in section or casting. 2,9, and secured thereto by screws 36, the outer face of said plate being in alinement with the parting plane of the two sections, 29 and 30. The plate covers a groove 37,. extending longitudinally through section 29,. and in which reciprocates rod 38, having integral therewith at its rear end a plate 39, which fits into arecess L0 in section 29,. The outer face of plate39 is preferably in alinement, with the outer face of plate 35, and has secured thereto, at its forward end a projection 4,1, extending laterally into the passage 32;. The said plate 39 with its projection ll constitutes a. hammer for impel ling the. projectile, 3 3, and plate 35 constitutes a stop for limiting the forward movement of plate or hammer 39. The forward end 42, of the rod 38 is hook-shaped for the attachment thereto of one end of a tension spring 413, the other end of which is secured to the section 29 near its forward end by a screw 44, the said screw and spring being ccntained within a cavity 45 in section 29. The cavities or recesses 37; and a5 are of less height han the passage 32, the shoulders 46, ining formed thereby, serving to guide the pr jectil An opening 47 for inserting the discs 33 into the passage 32is provided in thetop of the barrel in juxtaposition to the plate 35, and opens into, passage 32.

Plate 39. hasa recess 43 adapted to receive one end of a lever 49, located under plate 39 in a recess 50, in section 29, andv pivoted on a pin 51 fixed in section 29. The lower end of lever 49 is engaged by a v stanwheel trigger 52, pivoted on a 'pin 53, fixed to. section 29, and in a cavity 5% formed in both sections 29 and 30. The star-wheel trigger 52 has a plurality of radially-extending arms. 55', in the present instance four, the outer ends of which are preferably rounded onthejr forward portions 56, and terminate abruptly on their rear to, substantially right angle corner edges. 57. A spring blade 58, fixed in section '29, projects forward into cavity 54L so as to intercept the arms duringrotation. of wheel-trigger 5'2, acting as a pawl to. prevent wheel 52 from rotating backwards, andmamtaining it in proper initialposition, as shown in Figure .2. a

' The mod ler using. his. appara u i now be briefly, e cribe Thegun is n rmally inclined as shown in Figures 1, 2, and

3, being held so because of the preponderance of the weight of that portion of the gun outside of the case 1. A disc 33 is inserted into the slot 47, and assumes the position indicated by the dotted line in Figure 2.

The gun is next sighted toward the target, and the downwardly extending arm. 55 is pulled toward the handle of the gun in a typical trigger manipulating fashion, rotating the trigger wheel 52 in a clockwise or forward direction, When the trigger wheel 52 has been rotated through almost a quarter of a revolution, the parts are in the position indicated in Figure 3, the hammer 39 being retracted to its rear position, and the projectile 33 having rolled down the inclined passage 32 until it has become seated against the shoulder 34, whereby it is held out of contact. with hammer project-ion H. When the wheel 52 has been turned through its full quarter of a revolution, that one of the arms 55 which has been in engagement with the lever 49 will have passed abruptly out of such engagement by reason of the abrupt corner edge 57, whereby lever 49 andhammer 39 are permitted, to re-.assume their initial positions under the influence of the spring 43. Hammer 39 has acquired considerable speed in its forward stroke when projection l1 impact-s against projectile 33, so that the latter is discharged with suflicient force through the passage 32. Blade spring or pawl 58 bends, as, shown in dotted lines in Figures 2 and 3, to clear arms 55 during the forward rotation of wheel 52, but prevents undue backward movement of the latter.

Figures 8 and. 9 show a modification in which a resilient bufier 59 is used in lieu of the rigid projection 41 of hammer 39 for impacting the projectile 33. Buffer 59 is formed on the end of rod 60, which is adapted to reciprocate through lugs 61 and 62, projecting laterally from hammer 39. A compression coil spring 63 surrounds rod 60, being interposed between rear lug 61 and a pin 6% fixed in rod 60, the forward movement of buffer 59 under the. impulsion of spring 63. being limited by the contact of pin 64 with lug 62. In this modification the full force is not dissipated so readily in discharging the projectile as in the rigid projection v type, and a stronger action is, secured thereby because the spring 63 continues to act for a time after buffer 59 has engaged projectile 33. 1

Having thus described this invention, I hereby reserve the benefit of all changes in form, arrangement, order, or use of parts, as it is evident that many minor changes may be made therein without departing from the spirit of this invention or the scope of the following claims I claim 1- In a g n, the comb nation of pr j ti'le-impelling hammer, spring means tending to advance the hammer, a lever in operative relation with the said hammer, a starshaped trigger for operating the said lever, and a resilient element for preventing operation of said trigger in the wrong direction after having been actuated for operating the said lever.

2. In a gun, the combination of a projectile-impelling hammer, spring means tending to advance the hammer, a lever in operative relation with the said hammer, a starshaped trigger wheel adapted for operating the said lever by successive forward movements, and means for preventing undue re-' verse movement of said trigger wheel.

3.- In a gun, the combination of a hammer; a projectile-impacting butler resiliently impelled thereby, spring means tending to move the hammer forward, a stop for limiting the said forward movement, a starshaped trigger for retracting the said hammer, means for preventing reversed movement of said trigger, and subsequently abruptly releasing it, and means for seating the projectile so that it may be impacted at an intermediate point of the stroke of the hammer.

L. In a gun, the combination of a hammer, a projectile-impacting buffer resiliently impelled thereby, spring means tending to move the hammer forward, a star-shaped trigger for retracting the said hammer and subsequently abruptly releasing it, and means for seating the projectile so that it may be impacted at an intermediate point of the stroke of the hammer.

In testimony whereof I hereunto afl ix my signature.
