SPRING MARBLE-GUN Filed June 19, 1946 IN V EN TOR. 7mm 61 Kmzawc Y Patented Jan. 30, 1951 UNITED STAT-ES FATE N sermon a SPRING MARBLE GUN Frank S. Kralovic, Parma, Ohio Application June 19, 1946, Serial No. 677,810

3 Claims. 1

My invention pertains to a marble-gun and more particularly to a top adapted as a depository for a marble or other object to be propelled therefrom.

The advantages, besides durability and economy of manufacture, are-compactness, facility of operation and effectiveness of control after placing of -a marble to be propelled.

While the drawing exemplifies one structural embodiment of my invention, it is to be understood that the scope of my improvement comprehends equivalent modifications within the range legally to be ascribed to the granted claims.

Adverting to the drawing Figure 1 is a side elevation of a marble gun embodying my invention showing it grasped by the hand.

Figure 2 is a top plan view of the gun itself.

Figure 3 is an elevation of the left or forward end of the gun. V

Figure 4 is a plan view showing a presentation of my toy propelling marb es toward other marbles occupying spherically surface cavities in predetermined arrangement, alternatively to the scattered grouping thereof irregularly.

A generally curvilinear structure I composed either of sheet metal or of some suitable plastic comprises an approximately semicylindrical channel or runway 2 along which a marble M is to be propelled. The opposite end 3 is intended to serve as a handle which terminates as any approved desi n of whistle 4. The latter may serve to exercise an alternative function or may be blown simultaneously with propulsion of a marble as a preindication to'playmates of the users intention to take his turn in an endeavor to hit another marb e and to cause it to roll from the site where it had been deposited. As illustrated, the handle 3 is also of concavo-convex form merely as a manufacturing expedient or for economy of material. At its junction with the runway 2, the handle edges are rolled toward each other as ears at 5 to form a marble abutment and to present a smoother surface over which the operator's finger may be caused to side of the trigger is fashioned with an eyelet 10 which is intersected by one end of a coil spring I l which occupies a tubular formation l2 underneath the runway 2 and the formation carries forwardly a cap [3 through which the opposite end of the spring is curled at I4.

The spring normally tends to draw the trigger forwardly against the rear end of the runway, but when the spring action is overcome by finger pressure upon the bent upper end of the trigger preparatory to a release of the latter, a marble at the rear end of the runway may become propeled from the latter and if correctly aimed become projected so as to impinge a deposited marble, for instance, as shown in Figure 4, in any one of a series of cavities l5 distributed over the upper surface of a playing board l6.

Iclaim:

1. In a marble-gun, the combination of a support formed at its one end as a handle, at its other end as an open, concave channel having its rear end partially covered by rolled in ears and between said handle and channel with a slot; and a marble-projecting trigger resiliently connected with said support, having its lower end pivoted to said support and projecting up through said slot beyond the rear end of said channel; said trigger being adapted to travel between said ears and to impinge against a marble abutting said ears.

2. In a marble-gun, the combination of a support formed at its one end as a handle, at its other end as a channel and between the ends being provided with a slot, a marble-projecting trigger having its lower end pivotally connected with said support below said channel and projecting through said slot and above said handle and channel, a divided marble-abutment carried by the rear end of the channel walls and a spring connecting said trigger with a forward part of said support, said trigger being adapted, upon'its manual release from a position in which it is solely finger-held under the tension of said spring, to move within the confines of said abutment and to project a marble from said channel.

3. In a toy marble-gun, the combination of a structure formed at its one end with an arcuate channel, at its other end as a handle and intermediately with a depending portion of U-shaped cross section, said structure being slotted between the channel and handle and being furthermore formed with a slotted marble abutment straddling said channel and mechanism for pro 2,539,957 3 4 jecting a marble along said channel, said mech- R ER CITED anism comprising a trigger pivotally connected across said depending portion and normally projecting through and upwardly beyond the slot The following references are of record in the file of this patent:
