Description
Oct. l1, 1955 D. sLoBlN CAULKING GUN Filed NOV. l2, 1952 ATTORNEYS United States Patent O CAULKING GUN David Slobin, Brooklyn, N. Y. Application November 12, 1952, Serial No. 320,051 2 Claims. (Cl. 222--326) This invention relates to caulking guns and is an improvement over the structure embodied in my copending application Serial Number 237,352, liled July 18, 1951, now Patent No. 2,629,517, for Caulking Gun.
An object of this invention is to provide in a caulking gun an improved plunger rod which is U-shaped in transverse section and formed with teeth along the edges thereof which are engageable by the advancing dogs.
Another object of this invention is to provide an improved plunger rod for a caulking gun which may be produced by a stamping operation so as to thereby reduce the cost 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 drawing and specication, and then more particularly pointed out in the appended claims.
In the drawing* Figure 1 is a detailed side elevation partly broken away of a caulking gun constructed according to an embodiment of this invention,
Figure 2 is a front elevation of the device,
Figure 3 is a fragmentary sectional view taken on the line 3 3 of Figure 2,
Figure 4 is a fragmentary sectional view taken on the line 4-4 of Figure 3,
Figure 5 is a fragmentary bottom plan of the ratchet rod secured to the plunger,
Figure 6 is a fragmentary sectional view taken on the line 6`6 of Figure 4.
Referring to the drawing, the numeral 10 designates generally a caulking compound magazine which is formed of a cylindrical wall 11 having end heads 12 and 13 disposed at each end thereof. The magazine 10 is adapted to be mounted in a holder generally designated as 14. The holder 14 comprises an inner plate 15 formed with upper and lower arcuate llanges 16 and 17 within which the inner end of the magazine 10 is adapted to seat, and the holder 14 also includes an elongated transversely arcuate bar 18 xed to the lower flange 17 and provided at its outer end with a clamping plate 19.
A nozzle 20 of tapering configuration is carried by a cap 21 having an annular ange 22 which telescopes over the outer end of the magazine 10. The cap 21 is provided with a groove 23 within which a clamping bead 24 carn'ed by the plate 19 is adapted to engage. The plate 19 is formed with a slot 2S adapted to engage on opposite sides of the nozzle 21, and the nozzle 21 is formed with a bevelled outer end 26 through which the compound is adapted to be extruded and applied to the desired part.
The inner plate is carried by a handle 27, and an elongated plunger rod 28 loosely engages through the plate 15. The plunger rod 28 is U-shaped in transverse section and is provided with ratchet teeth 29 along the opposite lengthwise edges thereof. A plunger advancing lever 30 is pivotally carried by the handle 27 and a dog 31 is carried by the lever 30 and is adapted to engage the two rows of teeth carried by the plunger rod 28.
The plunger rod 28 at its inner end has a plunger member 32 secured thereto which engages within the flanged cap or head 13, as shown in Figure 3. The rear end of the rod 28 is angularly bent as at 33, so as to form a handle by means of which the rod 28 may be rotated through substantially so as to present the smooth curved side of the rod 28 to the dog 31 and thereby permit the rod 28 to be pulled rearwardly to a starting position. A holding or walking dog 34 is carried by the handle 27 in advance of the dog 31.
The outer end cap or head 12 is provided with a closure flap 36 which upon pressure being applied to plunger 32 is adapted to be forced outwardly into the inner or rear end of the nozzle 20. The plunger rod 28 is adapted to be formed out of stamped metal with the teeth 29 stamped therefrom at the time the rod is in flat or sheet form. By providing a plunger rod of channel shape with two rows of teeth carried by the two edges thereof, the entire gun may be produced at a smaller cost without any machine operations being necessary to form the teeth in the plunger rod.
In the use of this gun, the rod 28 is disposed in the position shown in Figure 1, when it is desired to extrude or force the caulking compound from the magazine 10. Lever or trigger 30 is rocked rearwardly to advance the plunger 32 and the rod 28 into the magazine 10. The rod 28 with plunger 32 may be pulled rearwardly from the magazine 10 by turning the handle 33 downwardly to a lower depending position, at which time the dog 31 will engage the curved smooth side of rod 28.
This gun is adapted to be made out of stamped metal and can be produced at a relatively smaller cost and at the same time provide a substantial magazine holder and gun for extruding the caulking compound.
I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims.
What I claim is:
l. A plunger rod for a caulking gun comprising an elongated stamped unitary sheet metal member having a U- shape in transverse section and ratchet teeth formed on the lengthwise edges of said member over an intermediate portion thereof and having smooth ends, one end of said member being bent at right angles to the length thereof and in a direction away from said ratchet teeth to thereby form a handle.
2. A caulking gun comprising a handle member, a plunger advancing lever pivotally carried by said handle member, a dog driven by said plunger advancing lever, an elongated substantially U-shaped plunger rod, said rod being provided with ratchet teeth along the opposite longitudinal edges thereof, said dog being adapted to engage said ratchet teeth to drive said plunger rod, said plunger rod being provided with an enlarged plunger member at one end thereof, the other end of said plunger rod being provided with a laterally extended handle, a holder comprising a plate fxedly secured to the handle member and adapted to receive one end of the caulking magazine, an elongated transversely arcuate bar attached at one end to said plate, said bar having its other end provided with a laterally extended clamping plate, said clamping plate being provided with a bifurcation at the free end thereof to receive therein the nozzle of the magazine disposed on the other end of the holder.
