TO ALL WIIOM IT MAY OONCERN:

Be it known that I, WILLIAM F. FAL'LS, of Boston, in the county of Suffolk, and State of Massachusetts, have iuvented an improved Marble-Shooter; and I do hereby declare that the following, taken in connection with the drawings which accompany and formpartof this specification, is a description of my invontion sumolent to enable those skilled in the art to practise it.

The invention relates to the construction of a device for shooting marbles, by which children a're enabled to project marbles with more preeision-than they can with the thumb and finger, as in the ordinary practice.

The inventien'consists of a istol or shooter ada ted to hold marbles of various sizes and havinfl' a s rinrrl P t i a a driver, and a trigger and coekng mechanism, with provision for setting the driverat half or full coclc, at pleasure, or accordingly as the marble is to be shot a greater or less distanee, or is to bc thrown with a greater or less impetus. i

The drawing roprcsents an instrument embodying the invontion, 'showing an end view, B a plan, and C a longitudinal central section of the arin or shooter. i v I a denotes a metal barrel, preferably east integral with the handle 1'. The rear part u of the barrelor tube is made eylindrical, and the ,front part d laring or trumpet-monthed, as seen at C. Through the topof the casting, and eonnecting with the tube e, is a'slot, e; and through the bottom, and opening into the, tube, is another slot, f. In the rear part of the tube e is a spiral spring, and in the front partv thereof a piston or driver, h, plays. This driver has a cock, r, projecting from its upper side through the slot a; and on its under side it has two notches z'. In an extension,= k,.- throngh which the slot f is made,a trigger, Z, is hnng on a'pin, m, one end of the' trigger, or a sere, n, thereon, projecting up through the slot, and being press'cd up against the piston by the Stress of a spring, o, forming part of the trigger, the sere slipping into the rear or the front notch i, accordingly as the piston is drawn partly or entirely back by the coek When so engaged, holding the piston in rear position, (or the piece cocked or half cocled,) if the trigger be drawn back, it will turn slightly on the pin m, releasing the piston from the serc n,rwhcvn the piston will be projected forward by the t expansion or stross at spring g. vThe marble to bc projected is placed in the month-d, the inclination of the sides of which is such that the marble impingcs against the surface of the flaring tube, and is thus hcld in place at any downward angle of the barrel a; and the month fits any sized marble which may be placed therein. I

The operation of the instrument is as follows: The piston is first drawn back, by means of the cock 'l',,to

either half or full cock, as may be desirable, the serc springing into its notch, as will be readily undcrstood.

The marble is then inserted in the mouth d, as seen at C, and the piece is re'ady for discharging. :By drawing back the trigger, the piston' is released from the sere, when the spring q will drive it forward, causing it to impel the marblo in the direction in which the instrument may be pointed. i

This little instrument is very simple .and effective for the purpose for which it is made, and is cheap and cndurinr'.

I claim a marble-shooter, having its parts eonstrueted and arranged to opcrate,and adaptcd to the projection of marbles of varying size, substantially as set forth.

WM. F. FALLS.
