WW Us Patented Apr. 3, 1951 UNITED STATES PATENT OFFICE 2,547,320 RADIUS GUIDE FOR CUTTING 'roa'onns Herbert S. Hedley, Banning, Calif. Application October 2, 1945, Serial No. 619,738
3 Claims.
My invention relates to cutting torches and has for an object to provide a guide for a torch through the use of which arcuate circularholes or arcs may be cut in metal in any position such as overhead, bulk-head, deck or otherwise positioned.
Another object of this invention is to provide a torch guide so formed that a circle may be cut and beveled in one operation.
Another object of my invention is to provide a torch guide having a center and means for adjustment of the guide relative to its work.
Other features and advantages, will become more readily apparent from the following description and the accompanying illustrative drawings in which:
Figure 1 is a plan view of my torch guide, the center rod being in section,
Figure 2 is an elevational View of the device,
Figure 3 is a sectional view on line 3-3 of Figure 1.
Figure 4 is a detailsectional view of a torch vided with a vertical bore it, El, E8 and it,
through which the screw ends 25, 2|, 22 and 23,
of bolts 24, 25, 26 and 21, are threaded and which form supporting legs for the spider, the heads 28 and 28' of the bolts forming feet for the device.
Vertically and adjustably mounted through the center of the spider is a rod or post 29, the lower end 3|] of which is threaded and terminates in a' center 3|. Lock nuts 33, 3 i, and 35 are provided to lock the legs after adjustment thereof.
A spacer ring 36, seats around the rod 29, and is held fixed by a set screw 36, and a lock nut 31, is threaded on the rod above the spider to lock the rod in the smooth bore 38, through which the lower end 30, of the rod passes. Adjustably mounted on the rod 29, and rotatable thereon is one end 39, of a carrier arm 40, for a radius rod 4|. The outer end 42, of said arm 40, is provided with a square slot 43, extending horizontally therethrough and through which the radius rod is slidably adjustable and which may be secured in fixed position by a set screw 44:. The member it, is adjustably mounted'upon the rod 29, through means of the spacer block 36, and the lock block 45, which is held in adjusted position on the rod by a set screw 3%. A knob 47', is formed on the upper end 48, of the rod 29, byrneans of which auser may hold the device in operative position.
Pivotally connected to the end 50, of the radius rod- 4|, is a socket member 5|, having an enlarged end 52, from which projects a pivot pin 53, which extends through aligning bores in a block 5 3 and radius rod iii. This block 55 has a slot 5 3', through which said end 59 of the radius rod 4| projects and is held thereto by a lock nut 56, on the threaded terminal 5'! of the pin 53. A clino-scale 53 is provided on the peripheral surface of the block 54, by means of which the member 5| may be set to a desired angle for a bevel cut presently to be referred to.
Seated within the socket 5|, is the reduced end 59 of a collar cc, provided with a serrated or fluted inner surface 6| adapted to receive the torch head 53, which is held secured in the collar by means of set screws 64, 65. The cutting tip 66 of the torch head projects far enough beyond the collar to drive its flame upon the material to be out.
In operation the radius rod 4|, is set by means of its scale 6?, and the index mark 68 on the up er surface of the arm til, to the half diameter of the circular out to be made and then locked by set screw id. The socket 5| is set by scale 58 to the bevel of cut desired and then locked by nut 56, and the center 3| will ordinarily be made to register with a punch mark on material to be operated on, the torch lighted and the device held in position by knob ill, and the cutting begun and continued by manually rotating the radius rod M.
It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.
Changes in shape, size and rearrangement of details and parts such as come within the purview of the invention claimed may be resorted to, in actual practice, if desired.
Having now described my invention, that which I claim as new and desire to procure by Letters Patent is:
1. A cutting torch guide comprising a spider having a centering rod axially adjustably mounted thereon, a carrier arm axially adjustably and rotatably mounted on said rod above said spider, a sealed radius rod longitudinally adjustably mounted on said carrier arm, and a socket member adjustably mounted on said radius rod to hold a cutter torch tip at various angles, for cutting beveled edged circular holes in substantially fiat sheet material, the radius rod being mounted transversely of said carrier arm and spaced from said centering rod a distance roughly corresponding to the distance of a cutter torch tip from the radius rod during operation of the cutter torch guide.
2. A cutting torch guide comprising a spider having a centering rod axially adjustably mounted thereon, a carrier arm axially adjustably and rotatably mounted on said rod above said spider, a scaled radius rod longitudinally adjustably mounted on said carrier arm, and a socket member adjustably mounted on said radius rod to hold a cutter torch tip at various angles, for cutting beveled edged circular holes in substantially flat sheet material, said spider having radially disposed arms and legs adjustably supporting said arms, the radius rod being mounted transversely of said carrier arm and spaced from said centering rod a distance roughly corresponding to the distance of a cutter torch tip fromthe radius rod during operation of the cutter torch guide.
3. A cutting torch guide comprising a spider having a centering rod axially adjustably mounted thereon, a carrier arm axially adjustably and rotatably mounted on said rod above said spider, a scaled radius rod longitudinally adjustably and transversely mounted on said carrier arm, and a socket member adjustably mounted on said radius rod to hold a cutter torch tip at various angles, for cutting beveled edged circular holes in substantially flat sheet material, said spider having radially disposed arms and legs adjustably supporting said arms, and said centering rod being threadedly secured on said spider and having an upwardly extending portion terminating in a knob to be used for steadying the torch guide during operation thereof, the radius rod being mounted transversely of said carrier arm and spaced from said centering rod a distance roughly corresponding to the distance of a cutter torch tip from the radius rod during operation of the cutter torch guide.
