` Figure2-is` a planiview of the blank from `Which the barrel structure is developed.

"Figure 3`-`is an enlargedlongitudinal sectional view through the barrel `showing Vthe trigger `and spring compressing element vin released'position;l i A i A Figure 4 is a similar View showing these parts incocked` position, and c f Figure v5 is a separate perspective Aview of certain :parts o`ftlie `air guna4 r A `Referring now moreparticularly to the `drawings wherein like reference `characters indicate like parts, Wllbe noted thatin Figure 1 there is illustrated an air consisting of a Vbarrel 1() and a stock 11.1 The barrel structure `is developed from a, blank 12, `see particularly Figure2, of substantially rectangular shape, Whichblank comprises aiportion 13 Whichis bent or rolledto form vthe barrel 10, with portions ligand With portions 15. The portions 14 are 4bent along the i y dotted lines 16 `to provide downwardly,eig@V tendingispaced flanges or`ears17 adapted to:

pivotally support the trigger, yet tobe referred to; Theblank is further bent laterale] i lyoutwardly alongthe dotted'lines 18M and` y then" rearwardly along the` dotted Alines 19 so that'the portions v15 extend reaihwardlyin spaced parallel relationto `formi the stock embracing ears2O.l The edges21of the por-- tion 13Y ofthe blankarearranged in overlapping relationand may' be spotWelded at suitable vintervals` `Thus `an integralstrucfA ture includingthe tubular barrel l0, trigger supporting ears `17- and stock 1 engaging ears 20,715 developed from fa single blank to pro-` duce unitary structure involving the, use A Vof securing'means only along the seamofithe v barrel. i ,t i, :w

Arranged Within the barrel-lOsa plunger 22 normally urgedto the position illustrated inA Figure Baby means of a spring`28which engages at its Arear enda stop pin 2&1` fixed `Within the barreh `Th'e 'plunger 22 `is icon'- nected by means `of arod- 25 to anelement 26 which constitutes a spring `compressing' or cockingxlever i and atrigger.` g The upper y; end 27 constitutes the" cooking lever and the `lower end 28 the trigger-propernwhichisprovided with a finger, portion 29.\` `"l`hefleverfportion 27eXtends` upwardly through a slot 30 formed in the barrel while the trigger portion is locatedvbetvveen the trigger supporting ears 17.

The element 26`is"mounted for both Aa pivotal andshiftablemovement by means of a pin extendingbetween theears 17 and a slot 32 formed in theelement 26. The element 26 and slot `connection which ,includesla pin 31 aan is providedrvvith a sear portionvvhich comf prises a `notch orshoulder 33 Which is adapted `to engage the shoulder or edge 34 of the gun barrel..Arrange'd immediately ladjacentA A the notchBB,isracamsurface 35 which during the cocking movement of the element is adapted t-o engage the shoulder 34 and shift the element with reference to its pivot pin 3l, in a rearward direction, so that the notch 33 may be brought into registration with the shoulder 34 to permit an engagement between these parts which holds the element 26 in cocked position. This position of the parts is illustrated in Figure 4.

In practice, in cocking the gun, the upper end of lever 27 is grasped and the element 26 i swung rearwardly about its pivot 3l against the action of plunger spring 23. As the ele ment 26 is swung rearwardly the element remains in its forwardmost position, that is with the pin 3l located in the end of slot 82 nearest the gun stock. However 'during this swinging movement of the cooking lever Vthe cam surface 35 engages the shoulder 34 and shifts the element 26 rearwardly during which time the slot 32`moves until the pin is adjacent the frontend thereof. Thereafter, when the cam surface has cleared the edge 34 the pressure of spring 23 moves the Yelement 26 bodily forwardly to cause` an engagement betweentlie sear portion or'notch 33 and the edge 34. The parts are thereupon in the position illustrated in Figure 4 in which the plunger spring 23 is compressed and the gun is cocked. In releasing the spring 23 the trigger porti-oirot1 the element 26 is engaged by the tingerportion 29 to shift the element 26 rearwardly sufficiently to move the notch 33 out of engagement withV the shoulder 34 whereupon the plunger 22 is released and the gun discharged.

From the foregoing it will be apparent that the present invention not only'provides a structure which may be manufactured with facility but one in which the costof manufacture is reduced to a minimum. The cost of production and lof assembly-is materially reduced by reason of theiactv that the air `gun structure herein described comprises a minimum number of parts.

In view of the obvious changes which may be resorted to without departing from the spirit and scope of this invention, reservation is made to make such changes inthe details of construction as may come within' the purview of the accompanying claims.
