" '4 Claims. (01. 30-95) My invention relates to improvements in end on rod cutters. It more especially includes the showing jaws and cutters formed integrally with shown thereon and described herein.
- Fig. l is a side elevation in section showing the cutters in position against a rod which is to be cut on. I
Fig. 2 is a front end elevation of Fig. 1 showing the jaws.
Fig. 3 is a. front end elevation of the jaw holder showing the jaws removed.
Fig. 4 is a top plan view of a detached cutter holding jaw.
Fig. 5 is a front elevation of 'a conventionally known ratchet wrench.
Fig. 6 is an enlarged diagrammatic elevation each other and positioned in the restricted space of a conical depression formed in the face of; a concrete wall.
Without departing fromthe broad spirit of the invention in its actual application to the formation of concrete or similar walls, I may use whatever expedients that the varying exigencies of practice may demand in the employment of cooperating alternatives or structural equivalent.
' In the formation of concrete walls, wooden form sidewalls are placed adjacent thespace.
that is to be occupied by the proposed wall.- Many rods are passed through both walls and on these rods against the inside facecof the wall,
cones are placed with their large ends against the 'form. They may be secured to external adjusting means which encircle the rods in any desired manner,- which adjusting means are placed on the projecting ends of the rods on the outside of the form; These are used to bring the walls into alignment and hold them against displacement while the concrete is placed in the interspace.
After the concrete has set, the forms are re,-
I moved, and the cones slid off from the ends of the rods. After the cones are removed a conical recess is left in the wall and the rods remain in the wall.
' 'jection B.
Sometimes these rods are removed entirely and the hole formed by them, as' well as the conical recesses formed by the cones, is filled with cement, or at other times, the'projeoting ends of the rods are simply cut off flush with the outside I faces of the 'wall and the conical recesses I onboth sides of the wall are" filled with cement In the ,use'of this'expedient, the ends of the rods being flush with the wall and the surroundingcement, they become'rustedand will disfigure' the wall face. i f 1 I overcome these defects, by cutting off the rod 1 somedistance in from the face of the wall, so that when the conical recess is filled with cement,-the cutoff ends of the rod will be completely covered, thus overcoming the disfigurement referred to. I v
To accomplish my purpose, I use a cylindrical member I that is of enlargeddiameter at the front end 2, presenting a threaded portion 5 between such end and the smaller diameter 3.. Adjacent the smaller diameter, a square end 4 formed. A hole 6 is formed throughout the length of the member. I. This accommodates the projecting. ends of rods '23.
A plurality of grooves l are formed lengthwise and externally of the body I. Aboutmid length of the grooves 1, projections 8 are formed in each groove. These projectionsserve as fulcrums for the cutter jaws'9. The jaws on the upper face are beveled at l2. The rear end of the jaws have an upward curve l0, and about midway of their length, a recess II is formed to. receive the pro- At the forward endof the jaws 9, removable cutters l3 passthrough openings in the jaws where they are held'by set screws M.
The cutters are moved into engagement with a rod to produce severing grooves is, through the rotation of a hand wheel 5 that moves endwis'e on the threads 5 and 18 until the bevelll engages the.incline 12 on the outer face of the jaws. The cutters l3 are retracted from the rod 23 by reason of the'threads 58 of the hand wheel l6 formed in its hub portion l5, engage the upturned ends ll] of the jaws, as the hand wheel is backwardfi thus radially moving such ends toward the center of the rod and at the'same time by reason of the-fulcrum 8 moving the cutters radially away from the rod. 7
A conventional ratchet wrench shown in Fig. 5, is used toengage the square end 4 to rotate the bodymernber l. Eachro-tation of the memberl with its attached jaws and cutters, will produce a groove of a certain depth in the rod. On the completion of such a groove, the hand wheel I6 is moved slightly to the right, so as to engage the bevel i! with the inclines l2. Thus the cutters 83 are moved into deeper engagement with the rod, after which the ratchet wrench 28 is again used on the square end 4 to carry the cutters entirely around the rod the second time, then the hand wheel is again operated and the process repeated until the rod is entirely or nearly separate. If just nearly separated, the projecting ends are easily broken off.
If desired, the hand wheel It may be substituted-by any desired form of ratchet manipu- I nally threaded sleeve for moving the cutters ralation.
The jaws 9 may be substituted by jaws 2i shown in Fig. 6, with which the cutters are integrally formed. The front end of these jaws are beveled so as to enter the conical recess 22 to a greater distance than square ended jaws might permit.
My present invention must not be confused with conventional pipe cutters, because none of these devices can possibly be used to out off a rod within a restricted recess as described above.
What I claim is:
1. In end-on rod cutters, a main member constituting the body having a rod opening throughout the length thereof, a plurality of external lengthwise grooves in such body, a projection constituting a fulcrum in each groove, an external threaded portion on the body of the member between its ends, threaded means external of the body member for movement endwlse thereon, a beveled opening in said means, a plurality of lengthwise cutter jaws in the grooves each jaw being provided with a notch adapted toengage thefulcrum, cutter terminations of the jaws at one end thereof, outwardly curving terminations at the other end of the jaws, inclined upper faces of the jaws, and means for rotating the body member to carry the cutters around the circumference of the rod. l
2. In end-on rod cutters, a body member provided with a rod receiving opening throughout its length and external threads thereon, a plurality of radially adjustable positioned attachable and detachable cutter jaws carried loosely by the body member, a fulcrum for the jaws approximately midway of their length, means external of the body member comprising a hand operated interdially inwardly and outwardly, and means for rotating the body member throughout 360 degrees and over.
3. In end-on rod cutters, a body member having a lengthwise rod receiving opening throughout its length, a plurality of cutter jaws, a plurality of grooves, containing radial projections formed in the grooves of the body member adapted to receive the jaws while fulcrumed on the projection, means forradially moving the cutters in the grooves toward or from the rod, said jaws having beveled faces near their front ends and integrally formed cutters, and means for rotating the body member throughout more than 360 degrees to form a groove in the rod of increasing depths throughout its circumference. I
l. In end-on rod cutters, a lengthwise jaw member having a curving upper face near the rear end and a beveled upper face near the front end, and a recess in its underside adapted to receive a fulcrum, and cutting means associated with the latter end of the jaw.
