CLEAN-OUT FOR PIPES Filed Aug. 28, 1931 :IIII-Ih I I 20 l WITNESSES Patented Nov. 8, 1932 UNITED STATES RANDOLF A. MIKALSEN, OF BROOKLYN, NEW YORK CLEAN-OUT FOB PIPES Application filed August 28, 1931.
An object of the invention is to provide a clean-out for pipes which is inexpensive to manufacture and which may be conveniently used to remove obstructions in pipes and conduits.
Another object of the invention is to provide a device of the character described in which a body member may be movedagainst an obstruction, and jaws mounted on the body 30 member may be moved forwardly to close in the front of the body member to grip the obstruction which has been engaged by the body member.
Still another object of the invention is to mount the jaws on a body member having sides with ends, the sides being connected by a web portion with curved ends which assist the movement of the device around bends in the pipe or conduit.
The invention furthermore comprehends a clean out for pipes in which resilient means are provided to rotate and close the jaws on pivotal means connecting the jaws with the body member, a catch held in operative osi- 9.5 tion by a trigger being provided to hol the jaws in open position and means being provided to pull the trigger to permit the escape of the jaws from the catch.
Additional objects of the invention will appear in the following specification in which the preferred form of the invention is described.
In the drawing similar reference characters refer to similar parts in all the views in which- Figure 1 shows a section of a pipe in which the device is positioned.
Figure 2 is a sectional view on the line 22 of Figure 1, and
Figure 3 is a cross section of the pipe showing the forward end View of the device.
By referring to the drawing, it will be seen that the body member 5 has a web 6 which connects the sides 7; the edges of the ends 8 of the sides 7 are converged, as best illustrated in Figure 2 of the drawing, and the edges of the web 6 also converge at the ends 9 of the said web member 6. This construction is provided so that the body member 5 may move readily through the interior of a Serial No. 559,970.
pipe or conduit 10 and around bends and curves in the said pipe or conduit.
Mounted on the body member 5, there are two jaws 11, one of these jaws 11 being disposed at each side of the web member 6, the aws belng plvoted at 12 to the sides 7 of the body member 5. The pivots 12 are disposed near the forward end 13 of the body member 5 so that when the 'aw members are in open position they may e disposed as shown by the full lines in Figure 2 of the drawing, but when the jaw members are in closed pos1- tion, they may extend in front of the forward end of the web member 6, as illustrated by the dotted lines in the said figure. Springs 14 are mounted on the pivots 12 and the ends of these springs engage the web 6 and the jaws 11 to move the jaws 11 to closed position.
The web 6 has a guide slot 15 in which is disposed a catch 16, the catch 16 having flanges 17 engaging the opposite sides of the web 6, the catch 16 also having ends 18 which are positioned for holding the jaws 11 in open position. It will be seen by referring to Figure 2 of the drawing that the ends 18 have diverging edges 19 which engage the jaws 11 so that when the catch 16 is not pressed in the direction of the jaws 11, the springs 14 will serve to move the jaws to free the jaws from the catch 16, and to coiitinue to move the jaws to closed position, as illustrated by the dotted lines in Figure 2 of the drawing.
Pivoted to the web 6 of the body member 5 at 20 there is a trigger 21 which is posi- 5 tioned to engage the catch 16 and hold the catch in operative osition with the jaws 11 in open position. ecured to this trigger 21, there is a lanyard 22, and secured to the body member 5, there is a flexible member 23, so that the body member 5 may be moved in the pipe or conduit 10 by the flexible member 23, and when the forward edge of the web 6 engages the obstruction 24 in the pi e or conduit 10, the lanyard 22 may be pul ed, which will free the trigger from the catch 16, thereby permitting the jaws 11 to move the catch 16 rearw'ardly, and the jaws to move to closed position and to grip the obstruction 24. The body member 5 may then be withdrawn from the pipe or conduit 10 carrying with it the obstruction or a portion thereof when, if necessary, the device may be used again to withdraw all portions of the obstruction.
