MARBLE-GUN. 1

Specification of Letters Patent.

Patented Sept. 3, 1912.

Application filed November 16, 1911. Serial No. 660,630.

T a1 Z whom it may concern Be it known that I, GEORGE Convm KEN- NEDY, a citizen of the United States of America, and a; resident of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Marble- Guns,-of which the following is a specification.

My invention relates to improvements in marble-guns, and the objects of my improvements are these: first, to provide a marble-gun with means for correctly sighting it; second, to render such sightingmeans foldable over upon the gun to per mit the whole to be easily carried in the pocket; third, to adapt the rear sighting means to act as a discharge trigger as well as engaging detachably the propelling means; fourth, to furnish movable pointers on the sighting-means to assist inlocating the object aimed at; fifth, to modify the form of the gun to permit it to be seated ina stable position upon the ground, and sixth, to adapt the gun and its said sighting-means to each other so as to permit the sights to fold over upon the gun toward each other, while being prevented from moving in opposite directions beyond the vertical. These objects I have accomplished by the means which are hereinafter described and claimed, and which are illus trated in the accompanying drawings, in which:

Figure 1 is a longitudinal vertical central? is a rear elevation of. the rear sighting. means, and Fig.3 is a rear elevation of the" forward sighting-means taken one trans versesection of the gun body.- Fig. 4' is a horizontal transverse section of the rear sighting-means taken on a line 3l of Fig. 2. Fig. 5 is a longitudinal vertical central section through the marble-gun of amodified construction, with the sighting-means shown in both full and dotted lines as in Fig. 1, the propelling-means set for discharge. Fig. 6 is a rear elevation of the rear sighting-means of the gun shown in Fig. 5, and Fig. 7- is a front elevation of the forward sighting means thereof. Fig. 8 is a detailed view of one of the rear coriiersof the gun-conduit, showing the method whereby the side standard of the sightingmeans is adapted to seat itself thereon to hold such means in either an erect or forwardly-prostrate condition.

Similar characters of reference designate corresponding parts throughout the several news.

The gun-body is a tube formed from a suitably shaped metallic blank which is bent over and its longitudinal edges in its middle portion united to produce a hollow cylindrical conduit adapted to receive marbles Z. The forward part b and the rear part c of said blank are not united at their longitudinal edges, but by means of a cut in each extending part wa) from their edges toward the middle line, the blank may be formed into a squared body at each end with vertical walls on each side, the squared bases of these parts 6 and 0 being thus adapted to be in line in the same horizontal plane and therefore provide a secure and stable seat for the gun on the ground or other flat surface.

Located partly within the gun-bore and partly in the squared rear channel 0 is a coiled compression-spring t, to whose forward end is secured a cylindrical solid head within the gun-bore a. Extending rearwardly from the head 71 and secured to it by a nail s, and within the hollow of said spring, is a rod p which has a finger-piece F72 and its upper edge is provided with a number of forwardly directed teeth 7'.

On the ends of the parts 6 and c are located the sighting-means d and m, alined in the middle longitudinal line of the gun. The rear sight comprises a plate (Z having a medial longitudinal slot (Z and a movable pointer c is slidably seated in said slot, the

pointer being formed of, a single small piece of metal bent to embrace the edges of the slot. The forward sight in is similarly formed but'shorter, and has a similar slot on and slidable pointer n.

The forward sight 1/?- is pivoted to the for ward part or corners of the part Z) above the line of the gun-bore, on a pintle 2. The part to which this sight is pivoted is projected above the upper edge of the part b on each side to form a raised part having a rearwardly-curved edge 7), over which laterallyproject'ed wings of thesight m move with a close-fitting contact. Since the forward part of said projection is angular, the sight when raised to a vertical position, cannot move forwardly from said position, though it may be swung rearwardly to a prostrate position along the gun ll as indicated by the dotted lines in Fig. l. The rear sight 11 is similarly mounted with like lateral wings which engage a. similar projection 0 on each. side, the projection serving to permit forward but not rearward swinging of the sight- The rear sight (l has its lower end divided to form a deep groove (1 therein, and the divided members thus formed are curved forwardly and pivoted on a pintle 1 to the sides of the part 0, said pintle also serving as a means of attachment and fulcrum for the rear end of the spring t. The inner transverse edge of the groove (1 in said sight is far enough from the pintle q to permit the teeth r of the rod p to be engaged by it when the sight is brought to its vertical position as shown in Fig. 1. However, the curving of the lower end of the sight changes the relations thereof relative to the rod-teeth r so that when the sight (Z is swung forward a little the teeth r become disengaged from said sight, which thus becomes a trigger with relation to said rod and spring. In other words, when the rod is drawn forward as much as desired, the sight (Z may be swung to a vertical position engaging the teeth '2, and may be held in that position until the aim has been adjusted, when the spring t may beinstantaneously released by merely swinging forward the sight (1 slightly. The plurality of teeth 7* on said rod 7) permits a number of adjustments of the tension of said spring to be made according to the distance necessary to cast the marble Z. \Vhen both sights have been lowered, the compass of the whole gun is small, and it may be easily carried in the pocket of the owner, while if desired, a ring j may be slid over the parts to keep them in place.

The device illustrated in Figs. 5 to 8 inclusive employs the same principles of operation generally, but with somewhatvaried details of construction. The same gun-body a, spring 2%, head k are used, but the rod p is formed of a resilient or yieldable rod which is bent upon itself to form a closed loop, the forward end 7" of the loop being made angular in order to permit it to engage the lower part of the sighting-device d at the rear when the latter is erected to the position shown in Fig. 5, and when the spring has been put under tension. The forward sight m is formed of a loop of wire, about which is slidably seated a looped pointer 01/. The lower ends of the members w and a: of the loop m are bent to cross each other, and their extremities are then bent outwardly to pass through orifices in the parts 7), then bent toward the plane of the loop m and then bent back to cross the vertical edges of the parts 5 when the loop at is erect. The angles of the parts I) are curved on the arc of a circle whose radius is the distance from the bearing-orifice in the part b to the contacting edge of said curved edge with the part crossing it, and the crossed part fits said curved edge closely with rubbing contact. ()n the-upper and vertical edges of said parts Z) are the notches 3 and 0 respectively, and the crossed parts of said looped extremities tend to drop thereinto when in the erect or prostrate position of the forward sight, as indicated in Fig. 5, the springiness of the member tending in each case to retain it in the notch in which it. may have been placed. For obvious reasons, the engagement is such, that the part on cannot be displaced forwardly from the vertical posit-ion, but it may be easily disengaged from the notch and then brought down to the prostrate position, in which last position it tends to be held by the notch y, rendering other retaining-means unnecessary. The rear sighting-means d" is of similar form to the one just described, and its crossed lower extremities similarly engage curved angles of the rear part c, and drop into locking notches h and i when either lowered or raised. The rear sight (2 has a similar slidable pointer e. The crossed extremities u and o of the rear sight are crossed almost horizontally to provide engaging means for the angle 1' of the rod p, and the ends'of these extremities f similarly bind in moving over the curved angles of the parts 0. When the aim is adjusted, the rod 79 may be yieldingly bent downward sufliciently to clear the crossed extremities u and o of the rear sight d, and thus the spring t is discharged.

It is to be understood that slight VZtIlL- tions, or equivalents of the parts described may be adopted in lieu thereof, without departing from the full scope and principles of my invention.
