1 Application July 18, 1951, Serial No. 237,352
' j olai (01. 222-327) This inveancu-re1atsto winking guns.
An object of this invention-is to provide in a caulking gun-an improved means-for supporting the magazine in a manner whereby the -material within the magazine may be extruded or ejected from the nozzle.
Another object of this invention is to provide in a caulking gun having a movable plunger engageable within a magazine, an improved means whereby the nozzle will be correctly positioned with respect to the handle.
A further object of this invention is to provide in a caulking gun an improved magazine support and alignment means whereby the magazine with the nozzle may be easily and quickly snapped into and out of operating position.
A further object of this invention is to provide in a caulking gun an improved magazine support which will rigidly support the magazine in axial alignment with the plunger so that the magazine will not shift or get out of alignment during the use of the gun.
A further object of this invention is to provide in a caulking gun an improved magazine alignment device and sup-port which is simple in construction and will not get out of order during the use of the gun.
With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claim.
In the drawings:
Figure l is a detailed side elevation partly broken away and in section of a caulking gun constructed according to an embodiment of this invention.
Figure 2 is a front elevation of the gun.
Figure 3 is a sectional view partly broken away taken on the line -33 of Figure 2.
Figure 4 is a sectional view taken on the line -$4 of Figure 3.
Referring to the drawing, the numeral ID designates generally a handle which has pivotally mounted thereto a plunger operating lever or trigger I 1 adapted to move a plunger rod. 12 forwardly into the magazine M. The plunger rod I2 is provided with ratchet teeth 13 on the lower side thereof, and the teeth l3 are engaged by a rear operating spring pressed pawl I4 movable forwardly with rearward rocking of the lever l I.
A holding spring pressed dog or pawl I also engages the teeth It so as to prevent rearward movement of the plunger rod l2 during the extrusion of the material from the magazine M. The rear end of the plunger rod I2 is provided with a right angularhandle or extension lfibyjme'ans o'f-wh'ich the rod l2 upon partial turning thereof to disengage the teeth" 53 from the p-awls l 6' and 15 may be moved rearwar-dly to a startin posie The magazine M which is of conventional construction is provided with a rear end head ll having an annular flange iii projecting rearwardly therefrom, and the magazine M is also provided with a forward head l9 having an annular flange 29. The head it is formed with a centrally disposed aperture 2! which is initially closed by means of a flap or closure 22.
The plunger rod l2 which is slidable through a guide opening 23 carried by the handle It) is provided at its forward end with a plunger head or piston E l. The head or piston 2% is adapted to engage within the flange l8 and to bear against the rear side of the rear head ill.
The handle it has-secured to the forward end thereof a plate 25 formed with an upper flange 26 and a lower arcuate flange 27. The front wall 23 of the handle it has projecting therefrom pairs of securing lugs 29 which engage through openings 39 formed in the plate 25.
A transversely arcuate magazine supporting arm 3| is fixedly secured to the flange 2'1 and projects forwardly beneath the magazine M to the forward end of the latter. An upwardly projecting plate 32 is formed integral with the supporting arm 3| and is provided with an upwardly opening slot 33 through which an extruding nozzle 3 1 is adapted to loosely engage.
The slot 33 forms a pair of fingers 35 at the upper end of the forward plate 32, and these fingers 35 are outwardly bent as indicated at 36 to facilitate the insertion and removal of the mega zine VI.
The nozzle 34 which is provided with an inclined mouth 31 is carried by a disc shaped plate 33 having an annular flange 38 telescoping over the forward end of the magazine M. The nozzle structure embodying the nozzle 3d and the cap which includes the plate 38 and flange 39 is retained in coaxial position with respect to the plunger rod i2 by means of a rearwardly projecting bead 4B which is formed in the plate 32 below the nozzle 35, and the bead 49 engages within a groove 4! which is formed in the cap plate 38.
The head 43 and the groove ii form a locking means for the nozzle structure so as to prevent this structure from disengagement with the plate 32 during the use thereof and also forms a means for holding the nozzle structure in axial alignment with the plunger rod [2.
In the use and operation of this gun structure the magazine M having the end caps l1 and 19 in the opposite ends thereof is inserted into the magazine holder, and at this time the plunger rod I2 with the plunger head 24 is disposed at its rearmost position.
At the time the magazine M is inserted into the holder the nozzle structure is slipped over the forward end of the magazine, and the nozzle cap is then snapped into position with the bead 40 engaging in the groove 4|. The plunger operating lever ll may then be rocked to move the plunger rod forwardly so as to thereby extrude the material through the nozzle member 34.
While the supporting arm or bar 3| is shown as being welded or otherwise fixedly secured to the arcuate flange 21 of plate 25 it will be understood that arm 3| may be made integral with flange 21 and plate 25.
What is claimed is:
In a caulking gun having a handle, a piston, and ratchet means for moving said piston, means supporting a magazine coaxial with said piston, said supporting means comprising an elongated transversely curved supporting arm, a right angular plate at the inner end of said arm, upper and lower magazine holding arcuate flanges on said plate means securing said plate to the forward end of said handle, a second plate carried by the outer end of said arm and formed with an upwardly opening slot, a nozzle seating in said slot, a cap secured to said nozzle adapted to engage over the outer end of the magazine, and a transversely disposed inwardly convexed bead carried by said second plate, said cap having an inwardly concaved groove within which said bead removably engages whereby said nozzle will be held in axial alignment with said piston.
