[Extending forwardly'irom and detachably secured to the'lowenpart': or the breech by the; transverse pins; 3 is a" barrel supporting arm 4fat the rear :end'; of which" the trigger guard 5"is?formed.v Ati'the' forward endof the arm-4 there is formedtlieiupwardly"extending; terminal 6 in. the;rear'fac e. of which is' formed a bore l for the reception of fonetend ofthe pin member 8. the forwardlyiacingfiwall ofthe breech 2 there is formed the chamberfif which opposes the rear'wallof the upstandingportionfif of the arm 5 and secured in .a suitable bore iil in the body of the breech is one 'iend' of a pin" H, which extends forwardly." through tlie chamber 9* and a short distance beyondjtheiorwardffaceofthe breech as shown .in' FiguresZ "and-'3'." V fI'hi'sfpinl I is aligned with the: pir the forwar-d end of the arm.

V Locatediabove. thefarm ifbetween' the forward faceofithe'breech 2' and the rear'face of the. up- I standingportion 6 of the arm is {a barrel which is indicated as a rwholeby'the, numeral 12. This barrelicomprises,a cylindricalfportion 13 which at 7 This head-is providedaatits-forward= end which is I fitted into the cylinder"! 3.;w-ith 'the axial chamber lfitinto' vvl'nlcl'r opens the axial bore 29 1 formed in the head fromtheoppositezend: In this bore 20 the-forward endioffthet'pin lili'engages and/as which projects radially beyond will be readily apparent the barrel I2 is, therefore, rotatably mountedupon this pin and the forward pin 8.

The rear end of the head I8 has cut thereinto the longitudinally extending slots 2| which open through theouter surface of the head'and through the rear end thereof as shown in Figures 2 and 12. The forward ends of these slots open into the chamber l9 and the number of these slots correspond to the number of pins' |6 which are carried by the forward head l4. Also, the slots 2| are each in alignment longitudinally of the barrel with a pin l6. 7 The head I9 is provided in its outer, surface with the circumferential channel or groove '22 in which is tightly fitted a wire ring or annulus23 and this groove 22 is so located that the annulus 23 passes over the slots 2|. w r

Oscillatably mounted in each of the slots 2| and upon the annulus 23 is a band holding finger 24 the oute'rsurface of the head |8 as-shown in Figures2 and 3." Disposed longitudinally of "the head l8 within the chamber I9 is a'series of. spring latch pins indicated as a whole by the numeral 25. Eachiof these pins is preferably rounded at its rear end and throughout a portion of 'its'length as indie cated at 26 and at its other end there is formed the right angularly turned terminus 27 which is the end 2'! is relatively thin and spring-like in screw 39 to the inner or forward end of the rear head l8 with the spring-like intermediate per-- tion '29 extending through the chamber and into a recess 2|, with thelrear end 26 projecting from the rear of the recess as shown in Figure 2. These rear end portions 26 of the spring latch fingers extend into the chamber 9 of the breech and are engaged 'by elements of the trigger mechanism of which they form apart." V

;The inner end of; the portionv 26 of each latch pin 25 constitutes a latch'shoulderwhich isindicated by the numeral 3| and the rear inner corner of the adjacent band {holding finger, 24 normally engages this'latch shoulder and is held thereby in .the normal outwardly directed position in which it is'illustrated in Figure-2.; In addition, each of these fingers i'siassisted in retaining this position bya springj32 which has .one end attached to the finger while the other or forward end is secured in a convenient manner as, f'orexample, to the laterally turned portion 21 of'the latch pin, inthe manner shown. Formed in the lower part of the breech 2 is a chamber 33 which opens into and forms a part of the chamber 9 and the opening provides'a means for'the gun trigger to'exte'nd from the chamber 33'into thearea of the guard 5.

Upon the pin'35 which extends transversely through the gun breech and through the chamber 33 is mounted the trigger member 36 which extends through the'opening 34 into the guard 5 in the manner shown andintegral with the pivoted end of this trigger is an arm- 31 which extends forwardlyandterminates' in the lower part of the'chamber 9. Spring means, such" as thatv indicated by the numeral 38, normallyurges the trigger 36'to swing forwardly tothe: position in wh ch it is shown in Figure 2.

The arm 31 is bifurcated at its forward end and the furcations are connected by a pin 39. Disposed between these furcations is the downwardly directed tail-piece 40 of a trip block 4| which stands uprightly in the chamber 9 and has theelongated vertical opening 42 for the extension of the pin therethrough. The tailpiece 40 of the trip block is also provided with a vertically disposed elongated slot which is indicatedj'by thenumeral 43 and through which the pin 39 passes.

Upon its upper end the trip block 4| carries the forwardly extending trip finger 44 which is disposed upon the vertical longitudinal plane of the barrel 2 and normally overlies the end 26 of aspring latch pin 25, being held and supported in thisposition by the pin 39 of the trigger arm.

'As shown in Figure 10 the pin 39 is extended at one enda substantial distance beyond the arm 31 and upon this extended end is oscillatably mounted the barrel actuating finger 45, the pin 35 passing through one end thereof. The other end of this finger is cut out to form a vertical abutment face'45 and a'lip 41 which extends forwardly therefrom. Theunderfacefof this lip is shaped to form the concave cam surface 48; A spring member 49 which is here illustrated as being carried upon the pin 35, engages and normally urges the free upper end of the vertically disposed"barrel revolving finger 45 forwardly. In the bottom-part of the chamber 9 there is pivotally mounted intermediateits ends upon the vertical retaining screw 5|] the bar 5l. One end of this. bar 5| has'a loose connection 52' with a barrel locking pin 53 which is reciprocably mounted in a'suitable' bore 54 formed in the breech 2 and opening throughthe forward face thereof; This structure is illustrated'in Figure 6 and "as is also clearly shown in this figure a coil spring 55 is housed in the bore 54 behind the pin 53 and normally urges the same outwardly where itmay engage its forward end in oneof the recesses 2| of therear-barrel head |8 to hold the barrel againstrotation. Theend of the bar 5| which is connected vviththe barrel locking pin 53 is remote from the end nearest the barrel rotating finger 45 as is shown in Figure 6. e

Inthe operation of the present gun the same is loaded by eng'aging over each'of the pins I6 at the forward end of the barrel |2,"one end of a rubber band 56 and stretching the same rearwardly until its other end mayibe engaged over a corresponding finger 24. Thiswill tend to draw or oscillate the finger forwardly against the tension of the holding spring 32-and if the finger 24 were not otherwise held the spring 32 would be of insuificient strength-to prevent the finger oscillating'under the infiu'enceof the band and the band would, therefore, have its rear end released. However, the innercorner of the finger is engaged against the latch shoulder 3| of the spring latch pin 25 and, therefore, firmly held against movement.

As previously stated the trip finger 44 of the block. 4| normally overliesthe rear end 26 of the uppermost or highest one of the pins 25 and from this it will be readily apparent that when the trip block 45 is pulled down the finger 44 will operate to spring the rear end of the latch pin bottom of the slot 43 in the tail-piece of the trip roomer I swinging downward of the-arm 31 before the trip lock M is moved, the surface-48 will cam against the underlyingpin -=and swing the finger' 45 'backwardly against the tension of the spring 49 as illustrated in Figure" 3. At the same time the rlngeri5 is moving across "the free end of the bar 5'l'but due to {the fact that it is swinging backwardly it does not affect the bar.

However, a point is reached in themovement or the finger I 45 where the forward edge of "the-lip 41 rides over-'- the' end of the pinii-with --'wh-ichthe camsuriace- 485 has been in engage- :ment, whereupon the spring 49" snaps the 'arm 45 forwardly bringing the abutment suriace or wall '46 against the end ofthe adjacent-pin fi and at the same time delivering a sharpblow upon the free end of the bar 151. Simultaneously with thisaction the trip finger 44' efiects the release of theadjacent-finger Z tandthe rubber band held thereby. The blow delivere'd'to the bar 5! swings rearwardly the end attached to the pin 53 and thus releases the barrel l2 so that when the trigger I 36 is released and "the spring 38 becomes effective to swing 'the'trigger back to its I normal =p0siti0n the barrel rotating fingerASwil be forced'to move upwardlyzand the lip 4'l thereof 1 will engage under'the :a'djacent pin"25 and impart sufiicientrotary motion to the barrel to bring another: rubber hand'holding finger zd into the position where the-spring glatch pin-zfi holding it has its "rear: end located :beneath the trip finger: 44. At the-same. time :a 'recess2l comes into position-to receive the barrel :locking pin Sti -and the gun is then.readyx for the discharge of another band.

From the foregoing it will be readily apparen that a rubber band shooting gun constructediin accordance with the present invention 'may ".be
