Filed May 17, 1943 Jame/ H COREOJ/ERO Patented July 25, 1944 UNITED STATES -P.A"I'lll\l' l' OFFICE TOOL v Joseph Corbosiero, Fitch-burg, Mass.
Application May 17, 1943,"Serial No. 487,222 6 Claims. (01. -10430) This invention relates primarily to a pipe or drain cleaning tool including cutters, but the device may also be used as ametal or wood cutting or reaming tool.
Objects of the invention include the provision of a relatively simple but rugged and efficient tool of the class described and embodying a construction which may be completely and easily taken apart, and in which a plurality of longitudinal cutters and a circumferential cutter are firmly secured together by means of a single screw or like fastener.
Further objects of the invention include the provision of an elongated tool of the class clescribed preferably having a pointed forward end forming a nut for co-action with a central rod for solidly securing a barrel cutter and a plurality of longitudinal cutters together in quick detachable relation, and including means providing for a mere substitution of the barrel cutter for providing a cutter tool of a different diameter, so that all parts but one are the same in various sizes of tools; and the provision of a tool as aforesaid wherein all the longitudinal cutters are exactly alike and manufacturable in a single die.
Other objects and advantages of the invention will appear hereinafter.
Reference is to be had to the accompanying drawing in which Fig. 1 is a view in side elevation of one tool according to my invention;
Fig. 2 is a View in end elevation of the tool;
Fig. 3 is a detail view of a blade holding washer; and
Fig. 4 is a side view of a cutter blade.
In the embodiment of the invention selected for illustration in the drawing, the character H) indicates a square rod located centrally and axially of the device and held at its ends by any desired means, but in this case detachably anchored in a pair of washers l2 and I4 respectively.
Washers l2 and I4 are both provided with centrally located recesses such as shown at I6 in Fig. 3 to closely receive the rod ends. These recesses are square to conform to the cross-section of the rod, the latter however being twisted 90 at its center so that the recesses in the washers, while facing, are relatively rotated 90;
Each washer is provided with further but smaller square or rectangular recesses such as at I8 for a purpose to be described, recesses l3 merging with recess I6 in each washer but preferably being shorter. Washer l4 may have a handle or handle fastener 20 secured thereto in any desired manner, but particular attention is directed to washer l2 in which the square depression I'B extends all the Way through, so that this washer may slideon the rod'. Washer I 4-may beofex- 'actly-the same construction if desired.
Rod l-B is provided at least at'its forwarder-left hand end in Fig. 1 with a'threadedextension 22 which is received in a tapped hole in a conical pointed front end element 24 so that the latter is securable to the rod and may slide washer I2 therealong upon turning up on the pointed element. Handle or handle fastener 20 may be secured to a like threaded extension on the other end of rod I0 is desired.
A circular one-piece unitary barrel cutter 2B surrounds rod [0, this barrel cutter having a front circumferential cutting edge 28 of a slightly greater diameter than a like rear or trailing cutting edge 30. These cutting edges are notched as for instance at 32 but at staggered locations as will be apparent from Figs. 1 and 2. Although the staggering is not necessary, several barrel cutters of dissimilar diameters are intended to be supplied with each tool.
The only remaining parts of the tool comprise longitudinal cutter blades 34, 36 which are all exactly alike. Each of these blades comprises a cutting edge 38 ground down angularly to a thick rear edge 40. At one end of each blade it is sharpened angularly with respect to the cutting edge 38 as at 42, the edge 42 however stoppin short of the thick edge 40 and allowing for a lug 44 having dimensions to fit depressions l8 in the washers.
At the .end opposite lug 44 each blade is bifurcated as at 46 to dovetail with notches 32 in the barrel cutter so that any cutter blade may be assembled with any notch and with the corresponding depression l8 in the washer. Lugs 44 each have a flat surface to contact a fiat surface of the rod l0.
Merely by tightening up on point 24, the entire assembly is firmly bound together into a rigid unit with no other fastening means. By removing the barrel cutter. a smaller or larger one can replace the same to vary the diameter of the tool, this merely inclinin the cutting blades 34 and 36 at a slightly difierent angle.
Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:
1. Atool comprising a central rod, a barrel cutter or the like having a forward cutting edge and a rear trailing edge of lesser diameter surrounding th rod'in spaced relation thereto, cutter blades locating the barrel cutter relative to the ends of the rod, said blades each having a' loose detachable connection at corresponding ends with a cutting edge of the barrel cutter and extending therefrom toward the ends of the rod, means to detachably anchor the remaining ends of the blades, and means to clamp said last named means to the rod and the blades to the barrel cutter.
2. A tool as recited-in claim 1 wherein the longitudinal; blades are bifurcated at said corresponding ends to receive said peripheral part of the barrel cutter.
3. A tool as recited in claim 1 wherein said remaining ends of the blades are provided with extending lugs to contact the sides of the rod, said anchoring means including a washer having depressions to receive the lugs.
4. A variable diameter elongated tool comprising a central rod, a pair of spaced washers on the rod, a generally circular hollow barrel cutter surrounding the rod and located intermediate the washers, a plurality of blades loosely mounted at corresponding ends on the peripheral edges of the cutter, means in the washers to receive the other ends of the blades loosely, and means to clamp the entire assembly together, so that said assembly may be taken apart and a cutter of different diameter substituted, said blades all being exactly alike and'interchangeable at both sides of the barrel cutter.
5. A tool comprising a central rod, a washer at each end of the rod, a generally circular hollow cutter having two circular cutting edges and surrounding the rod, a plurality of blades having corresponding ends loosely mounted on the cut-
