United States Patent 3.241.541 MARBLES GUN Francis 1. Coffey, Sr., 3908 S. Hill Road, Los Angelcs, Calif. Filed Apr. 18, 1962, Ser. No. 188,436 8 Claims. (Cl. 12427) This invention relates to a marbles gun and is more particularly concerned with a propulsion or catapulting machine for use in playing the game of marbles.

Marbles is a well known game played by children, wherein small balls of marble or like material and commonly referred to as marbles, are propelled by the persons engaged in the game, across a predetermined and marked-off or defined area of a flat, horizontal surface, such as the ground. The marbles are propelled so as to hit and/or drive other, like, marbles or balls, arranged within the area, out of said area. There are many Variations of the game of marbles, but one fundamental rule which must be followed is, that the player must propel the marble across the surface from a stationary point or location. That is, he cannot cast or loft the marble through the air and cannot throw the marble, as by swinging his arm. This last requirement necessitates that the marble be engaged between certain of the fingers of the players hand, usually between the thumb and index finger, and that necessary forces be exerted onto and through the marble by the players fingers so as to cause it to leave the players hand in a desired direction and with sufiicient velocity to accomplish playing of the game.

Unfortunately, many children do not have the strength, coordination, dexterity, or nimbleness required to play the game of marbles or to successfully compete with their playmates. As a result, these children are often ostracized and criticized by their more fortunate playmates.

An object of my invention is to provide a manually operable marble propelling mechanism, for use in playing marbles, which a child can use without breaking the fundamental rules of the game, that is, that the marble cannot be lofted and the hand must remain stationary.

Another object of my invention is to provide a machine, hereinafter referred to as a gun, which is such that small, weak, or handicapped children can partake in playing marbles with their playmates, but which is such that it does not provide such children with an undue advantage over their more skilled and capable playmates.

Another object of my invention is to provide a marbles gun of the character referred to having an elongate body with front and rear ends, a barrel or discharge chute at the front end of the body, a hand grip depending from the rear end portion of the body, a spring-actuated marble propelling mechanism within the body and said hand grip, and a trigger for said mechanism depending from the body forward of the hand grip and engageable by a finger.

A further object of the present invention is to provide a marble propelling mechanism having means for varying the force at which the marbles are propelled.

It is a further object of this invention to provide a marbles gun of the character referred to wherein the barrel or discharge chute is angularly related to the body so that its lower side occurs in a common horizontal plane with the lower or bottom end of the handle, and so that the marble or marbles discharged from the gun are propelled across the plane surface and are not lofted.

It is a further object of my invention to provide a marbles gun of the character referred to having novel means for retaining a supply of marbles and for feeding the marbles into engagement with the propelling mechanism, one at a time.

"ice

Another object of my invention is to provide a gun of the character referred to which is simple, highly effective and dependable in operation, and which is both easy and economical to manufacture.

The various objects and features of my invention will be more fully understood from the following detailed description of a typical preferred form and application of my invention, throughout which description reference is made to the accompanying drawings, in which:

FIG. 1 is a perspective view of my new marbles gun;

FIG. 2 is a rear elevational view of my new constructron;

FIG. 3 is a top view of my new marbles gun which portions broken away to better illustrate certain details of construction;

FIG. 4 is a sectional view taken as indicated by line 44 on FIG. 3;

FIG. 5 is a sectional view taken as indicated by line 5--5 on FIG. 3;

FIG. 6 is a sectional view taken as indicated by line 66 on FIG. 4; and

FIG. 7 is a view taken substantially as indicated by line 7-7 on FIG. 4.

The present invention relates to a hand-operated mechanism or machine for propelling small balls in playing the game of marbles.

The machine will hereinafter be referred to as a gun and the small balls will be referred to as marbles.

The gun A that I provide includes an elongate body B having fiat side walls 10, a rounded top wall 11, a bottom wall 12, front and rear end walls 13 and 14, and a central, horizontally-disposed partition 15, extending between the side walls and from the rear wall to the forward portion of the body where it terminates at a forward edge 16. The partition 15 defines an upper longitudinal chamber X and a lower longitudinal chamber Y in the body.

The upper chamber X is slightly greater in lateral and vertical extent than the marbles M and is open at its rear end to freely receive the marbles.

In the case illustrated, a detent means D is provided in the rear chamber X to prevent displacement of marbles from the rear, open end of the chamber. The means D is shown as including an aperture 17 in the partition and a leaf spring 18 fixed to the bottom side of the partition and having an upwardly-projecting part or portion .19 extending through the aperture and into the chamber X. The part or portion 19 of the means D normally yieldingly prevents the marbles M from moving longitudinally in the chamber X, past the aperture 17', but is such that the marbles can be easily and conveniently urged forwardly and into the chamber, past the means D, by light pressure exerted on the marbles by ones fingers.

The forward edge 16 of the partition 15 terminates rearward of the front wall 13 a distance slightly greater than the diametric extent of the marbles M and cooperates with the said front wall and the side Walls of the body to define an opening or passage 20 establishing communication between the upper end lower chambers X and Y and through which the marbles M, in the chamber X, are free to drop.

Projecting forwardly and upwardly from the front end of the body is an elongate, barrel-like discharge chute C having forwardly and upwardly-inclined front and rear walls 21 and 22, fiat side walls 23 and a curved bottom wall 24. The upper end of the chute is open. The side walls 23 are joined integrally with and project forwardly from the lower forward ends of the side walls 10 of the body. The bottom wall 24 is in the nature of a continuation of the bottom wall 12 of the body and fairs into or joins with the front wall 21 of the chute.

The lower edge of the rear wall 22 of the chute con- 3 verges with the lower edge of the front wall 13 of the body.

The lower rear end of the chute establishes communication with, and is, in effect, a forwardly and upwardly inclined extension of the lower chamber Y of the body.

In the case illustrated the upper end of the chute is truncated so that its open end occurs in substantially the same horizontal plane as the top 11 of the body B.

Depending from the rear of the body B is a hand grip G. The grip G has a pair of flat side walls 26 depending from the side walls of the body, a rear wall 27 continuously downwardly from the rear Wall 14 of the body, a front wall 28 and a rounded bottom wall 29.

The upper portion of the front wall 28 and the portion of the bottom wall 12 of the body adjacent the front wall 28 are provided with a forwardly and downwardly-disposed slot-like opening 30, to freely receive a trigger T, as will hereinafter be described.

A suitable trigger guard 31 is provided to extend forwardly from the handle, adjacent the lower end of the opening 30 and then upwardly to join the body at a point spaced forwardly of the front end of the opening 30.

The structure thus far described is preferably formed of plastic in accordance With conventional plastic manufacturing methods and procedures.

Arranged within the chamber Y and handle H is a spring-loaded drive means L to drive or urge the marbles M forwardly from the forward end of the chamber Y and outwardly through the chute C.

The means L includes an elongate drive bar or slide 40 having front and rear ends 41 and 42 and a pair of longitudinally-spaced, slotted openings 43. The slide 40 is provided at its forward end with a block-like marbleengaging head 44, formed of rubber, or the like, and provided with a flat, forwardly and upwardly-inclined front surface 45. The slide 40 is shiftably supported in the chamber Y by a pair of longitudinally-spaced support pins 46 fixed to and extending between longitudinallyspaced, opposing block 47 formed on the inner surfaces of the side walls 10 of the body. The pins 46 project through the slotted openings 43 in the slide. The blocks 47 serve to freely slidably engage the opposite sides of the slide and to maintain it in a vertical plane and in the center of the chamber Y.

The rear end 41 of the slide is provided with a rearwardly-projecting spring-retaining projection 49,

Arranged in the handle or hand grip G is an elongate, vertically-disposed leaf spring 50. The lower end of the spring 50 is engaged against the rear side of a laterally, inwardly-projecting stop 51 provided on one of the side walls of the handle, at the rear portion thereof. The upper end of the spring 50 bears against the rear end 41 of the slide 40 and is provided with a slot opening 52 through which the retaining projection 49 on the slide is engaged. Arranged in the forward central portion of the handle G is a vertically shiftable fulcrum bar 55 which occurs adjacent and bears against the rear side of the spring 50 at the central portion thereof. The bar 55 is in the form of a simple, cylindrical pin, the ends of which project through elongate, vertically-extending, registering, slotted openings 56 in the side walls of the handle. The ends of the bar or pin are provided with finger-engaging and retaining pads 57, which pads slidably engage the outside surfaces of the handle.

The rear edges of the openings 56 are provided with vertically-spaced, forwardly-opening pin or bar-receiving notches 58.

With the vertically shiftable fulcrum bar set forth above, it will be apparent that vertical positioning of the bar and the resulting effective force of the spring on the slide can be effectively varied or adjusted, as circumstances require,'by engaging the pads 57 on the bar, between ones fingers, urging the bar forwardly against the resistance of the spring 50 and out of engagement in certain of the notches 58, then sliding the bar longitudinally in the slots, either upwardly or downwardly, as circum- 4- stances require, and then releasing the pads and allowing the spring to urge the bar rearwardly into engagement in other adjacent and related notches 58.

The forward end of the slide normally projects forwardly and beyond the forward end or edge 16 of the partition 15 in the body, so that the marbles M in the chamber X, at the opening 20 defined by said edge 16, side walls It) and front wall 13, is prevented from dropping into the lower chamber Y.

The slide is stopped in its forward, normal position by the pins 46 which are engaged .by the rear ends of the slot openings 43 in the slide 40.

Upon rearward shifting of the slide in the body relative to the pin 46 and against the resistance of the spring 50, the forward portion of the slide is shifted out of position below the opening 20 establishing communication between the chambers X and Y (and allowing the marble in the chamber X at said opening to drop into the chamber Y, forward of the head 44 on the slide 40.

To normally prevent shifting of the marble in the chamber Y forwardly and outwardly therefrom, I provide a keeper spring 59 in the upper forward end of the chamber Y, where it communicates with the chute C. The spring 5? extends laterally between the side walls 10 of the body and yielding-1y engages the upper forward portion of the marble in the chamber Y. The spring 59 is shown as an elongate coil spring having its opposite ends engaged in aligned openings in the side walls 10 of the body.

\Vhen the slide has been urged rearwardly in the manner set forth above, and against the resistance of the spring 50, and a marble M has shifted into the chamber Y, it will be apparent that upon releasing the slide, so that it is urged and shifted forwardly by the action of the spring 50, the marble M is engaged by the head 44 on the slide and is driven past the spring 59 into and through the chute C to be discharged therefrom and across the surface with which the gun is related.

The bottom wall 24 of the chute serves to change the direction of travel of the marble so that its direction of travel is parallel with the central axis of the chute, and the inclined front surface of the head 44 on the slide imparts sufiioient desired english on the marble so that as it is driven out of the chamber Y across the bottom wall 24 and thence outwardly from the chute, the marble will not jump or hop, but will move smoothly and directly through and out of the chute.

The slide 40 can be shifted from its forward to its rear position in any desired or suitable manner, and is releasably held in its rear position and against the resistance of the spring lay the trigger means T, referred to above, which trigger means can vary widely in form and constrwction. The trigger means T is basically a simple, manually-releasable latch means.

In the particular case illustrated, the trigger means T serves to urge the slide 40 rearwardly and to release the slide when it has reached its rearmost position.

The trigger means T is shown as including an elongate, longitudinally-dispiosed arm 60 arranged in the chamber Y to occur adjacent one side of the slide 40. The forward end of the arm 60 is provided with an elongate slot 61 through which the forward support pin 46 projects. The slot 6 1 is equal in longitudinal extent with the slotted openings 43 in the slide and with the travel of the slide.

The relationship of the pin 46 in the slot 41 serves to pivotally secure the forward end of the arm in the body and yet allow for limited longitudinal movement of the arm in the body and relative to the slide.

Depending from the rear end of the arm 60 is a fingerengaging tab or trigger 62, which trigger depends through the opening in the bottom of the body and into the confines of the trigger guard, as clearly illustrated throughout the drawings.

The trigger 62 is provided with a laterally projecting ear or dog 63, which dog engages in a downwardly-opening notch 64 in the bottom edge of the slide 40. The

dog 63 and notch 64 in the bottom edge of the slide 40 are so positioned or arranged that the dog enters the notch when the slide and the arm of the trigger means are in their forwardrnost position.

A rat trap type spring 65 is carried by the arm intermediate its ends to bear against the bottom wall of the body and to normally yieldingly urge and pivot the arm upwardly and the dog thereon into engagement in the notch in the slide.

The trigger 62 is further provided with a rearwardly and downwardly-inclined cam face or edge 66 at its upper rear portion, which surface normally occurs forward of the rear support pin 46 carried by the body, as illustrated in FIG. 5 of the drawings.

When the trigger means T and slide are urged rearwardly, the cam 66 initially engages the lower side of the rear support pin 46. Upon continued rearward movementof the trigger means T, the arm 60 is urged down- .wardly' against the resistance of the spring 65 and the dog 63 is urged out of engagement in the notch '64, by the action of the cam, with the result that the slide is disconnected or released from the trigger means and is free to shift forwardly and to drive a marble M in the chamber Y there/from, as clearly illustrated in phantom linesin FIG. 5 of .the drawings.

- vlit will be apparent from the above that the loading,

that is, urging the slide rearwardly against the spring 50 and-allowing a marble M to enter the chamber Y, and

releasing the slide, to drive the marble from the construction, is accomplished by the single motion of urging the trigger 62 rearwardly relative to the body and handle. it The force required :to be exerted on the trigger 6-2 to 'urge the slide rea'rwardly, is controlled by the positioning of the fulcrum bar related to the spring 50, as described above.

For the purpose of describing the structure that I provide, I have stated in the preceding descriptive matter and in FIGSJZ to 7 of the drawings have shown, the body of my marbles gun being horizontally disposed and the chute C thereof being forwardly and upwardly inclined. In practice, however, and as illustrated in FIG. 1

of the drawings, the chute C is horizontally disposed, the body B is'rearwardly and upwardly inclined. The front wall 21 of the chute, when the gun is thus arranged, is,

a I With the above relationship of parts, the body and the handle establish an arch or bridge .over the playing surface and define sufiicient space above the said playing surface to freely accommodate those portions of the players hand which occur forward of the handle and below the body. The above relationship of parts also enables the player to urge the gun into firm engagement on the said playingsurface, for steadying the gun against uncontrolled movement of the players hand when his energy is being directed to pulling the trigger, as well as to enable steady aiming of the gun.

Having described only a typical preferred form and application of my invention, I do not wish to be limited or restricted to the specific details herein set forth, but wish to reserve to myself any variations or modifications that may appear to those skilled in the art and fall within the scope of the following claims.
