June 8, 195 A. MILAZZO ATTACHMENT FOR USE WITH BURNING EQUIPMENT Filed March 8, 1954 ATTACHMENT FER USE WHTH It EQUWMENT Anthony Milazzo, Brooklyn, N. Y. Application March 8, 1954, Serial No. 414,908 7 Claims. (Cl. 266-23) (Granted under Title 35, U. S. Code (1952), see. 266) burning equipment and more particularly it relates to an attachment for use with mechanized burning equipment that permits the cornoletion of a burning operation in one uninterrupted traverse of the burning equipment.

Where the need arises to modii a structural member such as an l-beam by cutting away either part or all of one side or both sides of one of its flan es along the entire length of the beam, resort is usually had to mechanized burning equipment. To perform the burning operation expeditiously, a metal burning torch or a pair of metal burning torches is mounted on a mechanized crse ec' hreat. The mechanized traverse equipment generally includes a carriage provided with power driving means and further includes a plurality of rollers driven by the power driving mea s to propel the carriage along the length of the structu l member. The metal burning torches are adjustably secured to the carriage. As the carriage moves along the length of the structural member, the metal burning torches are adapted to separate by burning the undesired portion(s) of the beam along its cn.'re length from the main body of the beam. The torhcs are attached to one end of the carriage. When the m .chanized equipment is at the beginning of its traverse which is at one end of the beam, the burning torches are positioned to begin cuttting away the undesired portions of the beam beginning at the one end of the beam. However, it is possible to perrorm the entire burning operation along the entire length of the beam in one continuous traverse of the carriage. if the carriage were to continue moving when it approached the end of the beam opposite the starting end the carriage would drop right off the end; even at that the torches would still not have completed tie burning operation along the entire it is a conventional procedure, at present, to stop the carriage as it approaches the end of the beam, extinguish the cutting torches, take the carriage oil the end of the beam, turn the carriage around, and then remount it on the beam so that it is ready to complete the burning operation by starting from the end opposite the starting end and moving toward the starting end. Tie burning torches thereby are able to complete the burning operation.

This invention marss a departure from the prior art in that it provides an extension adapted to be conveniently attached to the end of a structural beam prior to the beginning of the burning operation. The attachment provides an extension of the supporting surface for the rollers of the mechanized traverse equipment. The attachment has supporting means at one end and a convenient attaching means at the other end for securing the attachment to the structural member in an aligned relationship therewith. The attachment is designed to accommodate a range of sizes of beams.

An object of this invention is to provide an attachment for use with burning equipment.

A further object is to provide an attachment for use with burning equipment that is adapted to eliminate the need for reversal of the burning equipment prior to completion of a burning operation.

A further object is to provide an attachment for use with burning equipment permitting a complete burning operation once the equipment is set up.

A further object is to provide an attachment for use with mechanized burning equipment to permit a complete burning operation in one traverse of the burning equipment.

Ot 131 objects and many of the attendant advantages of this invention will be readily understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:

The single figure shows a preferred embodiment of the attachment of this invention partially broken away and secured to one end of a structural member only a part of which is shown on the drawing.

There is shown on the drawing an attachment 10 for use with mechanized metal burning equipment. For purposes of illustration and not in any limiting sense, the attachment it is shown secured to one end of an elongated structural l-beam 11, having an upper flange 12; only a small broken away portion of the I-beam 11 is shown on the drawing. The end of the I-beam 11 is not altered in any manner prior to securing the attachment It) thereto.

The attachment it) includes an extension 13, preferably in the form of a section of T-beam. The section of T beam 13 is of a lightweight metal or other strong material. Lightweight material is preferred so that it may be handled easily in transferring it from one workpiece to another workpiece. Aluminum has been found to be suitable. The section of T-beam 13 has a web 14.

Securing means, generally shown at 15, is provided for securing the attachment 1t) relative to the beam ll. The securing means 15 includes a right-triangular section or flat plate 16. One of the perpendicular sides of the section of flat plate 16 is welded to the web 14 of T- beam 13 adjacent one end thereof so that the former and the latter are coplanar. The side of the section of flat plate 16 perpendicular to the side welded to the web 14 is aligned with the end of the web. Welded to each surface of the right-triangular section 16 is an attaching means 17. Each attaching means 17 includes a longitudinal leg 21 and a transverse leg 26. Threadedly engaged Within tapped holes in the transverse legs 26 are bolts 13, 19, and 2h. The clamping bolts are arranged to engage the web of the beam 11 when the latter is disposed in the space between the attaching means 17. Additional bolts 27 are threadedly engaged within tapped openings in the ends of longitudinal legs 21. 'By virtue of their position, bolts 27 not only engage the web of beam 11 for the purpose of clamping but in addition serve to align the attachment 1t) longitudinally relative to beam 11. Set screws 22 are threadedly engaged in tapped holes in transverse legs 26. The set screws 2?. serve initially to engage the web of beam 11. Being of the socket type they may be conveniently manipulated simultaneously to align the web 14 of the section of beam 13 with the web of beam 11.

Each of the transverse legs 26 is further formed with a cutout 24 adapted to receive the ends of the lower flange of beam 11. By this arrangement it is possible for the attachment it) to be used with a greater range of sizes of I-beams than would otherwise be possible.

Shields 23 are adjustably secured to the longitudinal legs 21 of the attaching means 17. The shields 23 are flat copper members. They are formed with elongated slots 25. Fastening screws 29 are passed through the elongated slots 28 and are threadedly engaged within the longitudinal legs 21 for retaining the shields 23 in fixed relationship thereto. The elongated slots permit the shields to be adjusted according to the thickness of the web of beam 11.

Since the weight of the attachment 1% plus the weight of a mechanized burning equipment is too heavy for the attaching means 16, an auxiliary support 25 is provided for the attachment 10. The auxiliary support includes a pair of telescoping members 31 and 32 and thumb screw 33. Telescoping support 25 is pivotally secured to the T-beam 25 by a pivot 34. The thumb screw 33 on the telescoping support 25 permits for adjustment of the supporting end 32.

In operation, the attachment 19 is first brought in o position at the end of I-beam 11 manually and then while holding the attachment 1% so that the surface of the flange of the T-beam section 13 is substantially coplanar with the surface of flange 12 of I-beam 11, the set screws 22 are tightened against the web of the l-beam 11. Through simultaneous manipulation of the wrenches engaged in the sockets of the set screws, the end of the web 14 of the section of T-beam 13 is aligned with the web of the I-beam 11. The attachment 10 is then aligned longitudinally with respect to the I-beam 11 by selective tightening of the bolts 27. When the bolts 27 are finally tightened the attachment 10 is partially secured. Subsequently, the bolts 18, 19, and 20 are tightened to finally secure the attachment 10 to the I-beam 11. The copper shields are adjusted by loosening the screws 29 and sliding the shields to their inmost positions abutting the web of the beam 11. As the mechanized burning equipment proceeds along the beam 11 and approaches the end shown on the drawing, one end of the equipment approaches and comes into engagement with the attachment 10. Motion of the mechanized burning equipment continues until the burning operation is completed along the entire length of the beam 11. At that time the mechanized burning equipment is brought to rest entirely on the attachment 10. As the metal burning torches pass over the shields 23 the attaching means 17 is protected against the flame of the torches by the copper shields 23. By this arrangement the burning operation is completed in one traverse of the equipment without the need for additional handling with consequent loss of time.

Obviously many modifications and variations of the present invention are possible in the light of the above teachings. It is therefore to be understood that within the scope of the appended claims the invention may be practiced otherwise than as specifically described.
