To all whom t may concern:
Be it known that l, VVonrHY C. BUCK- NAM, a citizen ot the United States, and a resident of Marion', Jersey City, in the county ofHudson and State of New Jersey, have invented certain new andA useful lmprovements in Blowpipe Apparatus, of which the following is a specification.
rlhis invention relates to means for supporting and rectilinearly moving the jets of Oxy-acetylene or Oxy-hydrogen blow-pipe apparatus, or torches as they are commonly called, and is designed more especially for cutting, which, as is well known, is performed with a combination of heating and oxidizing agents, such as a jet of oxygen accompanied or preceded by an ignited jet or jets of a combustible mixture, tor example, oxygen and acetylene.
lThe object of the invention is to provide a simple apparatus whereby beams, rails or other bars may be cut conveniently, expeditiously and cleanly.
The device comprises a sup ort to be clamped to a beam, rail or bar, suitable jetdelivering means, and guiding and propelling mechanism whereby the jets are caused to travel atuniform speed across the bar, and it also includes provisions whereby the jets may be moved across diderent sides of the bar in succession, without changing the position of the clamp.
In the accompanying drawings illustrating the invent-ion by means of the preferred embodiment thereof: Figure 1 is a side elevation otfthe device; Fig. 2 is a vertical section therethrough; Fig. 3 is a side elevation showing the partsin changed position; Fig.
4 is a side elevation showing the parts in an other position; Fig. 5 is a detail sectional view; Fig. 6 is an elevational detail; and Fi 7 is detail sectional view.
he device is. supported on a beam, rail or other bar by means ot a clamp, comprising suitable jaws 10, 11 adapted to clamp Von opposite edges or flanges of the bar or beam or opposite'sides of the ball ot a rail, a screw 12 secured to the jaw 10 and a hand wheel 13 with internal threads engaging those of the screw to advance the jaw 11. The clamp is shown applied to the top angesot an l-beam.
rlhe jet-delivering means may be of various suitable forms. Preferably a torch such as 50 having a straight elongated body is employed. rThis body contains suitable conduits for leading the gases and is provided at the end with a suitable tip or nozzle through which the gases pass and are delivered in the form of two or more jets upon the work. The heatingjet, composed preferably ot oxygen and acetylene lis indicated at 16, and the cutting jet of oxygen alone is indicated at 17. lt will be understolod that the heating jet is a flame while thd cutting jet is of course invisible. The internal construction ot the torch with "its conduits, valves, and mixing provisions, may be of any suitable or known character.
rlhe torch has not been, illustrated in detail, but it may be substantially like that shown in my applicationlliledv May d, 1912, Serial No. 695,289. At the rear end it is provided with suitable connections, such as 14, 15 for the attachment of flexible pipes leading from the sources of supply. rlhere may be two of these connections or three, according to whether one supply ot oxygen is led into the torch and there divided, part going to the heating jet and part to the cutting jet, or whether two separate supplies of oxygen for the two kinds of jet are provided. The heating jet, as usual precedes the oxidizing jet in the travel along the line of the cut.
The preferred construction of the guiding and propelling mechanism whereby the jet-delivering means orl torch is caused to move across or around the beam or rail will now be briedy described." The jaw 10 has a wall 22 integral with it, arranged crosswise of the rail or beam and projecting upward or away from it. Un this wall is swiveled or pivoted a member or arm 23. To this end,ithe wall 22 is shown provided with a circular depression 24 which receives a circular projection 25 on the side and near the end of the member 23, and a suitable pivot 26 4is shown connecting the two. The member 23 constitutes a guide, which by virtue of the swivel connection, is angularly movable on the clamp or support. lt is shown as being formed with laterally spaced guide bars 27, the outer sides of `which are undercut. 'lhere is a second guide structure at right angles to the hrst and movable sidewise thereon; and it is shown as comprising a beam 28, having or being attached to a suitable carriage 29 mounted on and movable along the guide arm 23. The said carriage has suitable ianges 30 engaging the undercut side edges of the bars 27 and one of these flanges is preferably separate 'and secured to the carriage, so that' thelatter may be applied to 'and removed vfronrthe primary guide sidewise instead of overthe end. The second guide 28 is ropelled Sidewise along the iirst guide 23 y means of a screw` 31, journaled at its ends in the ends of the arm 23 and engaging a threaded orH nut portign 32 on the carriage 29. This threaded. part of the carriage 1s preferably in the nature of a half-nut, in order to en able the carriage tobe applied to and re moved from the primary guide in the manner described. A suitable carriage 33 is movable along the second guide 28. It. is
shown as provided with an undercut chan.a
pelling the jetfdeliveri'ng means at uniform speed, which is essential to successful cuttin r nick releasemeans-.may be provided for disconnecting 'either-or both of the carriages 29, 33 freni their screws. Such means is illustratedl in connectionv with the carriage ,33. Here the screw 34 passes through the carriage and engages two. opposite nut,
Suitable'means are' provided for holding the compound guiding and propelling mechagainst movement onthe pivot 26 at anlsm either of the positions to which it may be clamped, the. heating in a bore 1n the carriage'. forced into frictional, holding relation with the back wall in' Fig. 1 to thatfpfQFig. 3.` Stopsl46, 47 y on the wall 22 positioned'to be contacted by the oppositevsides or edges of the member 2 3 limit the movements in opposite directions. The -mechanism is held at either positionby the nut 48 on the pivot bolt 26, the same b'eing Vprovided with a handle `48* Afor quick operation.
It will be observed that the torch 50 in effect .constitutes a thirdrarm carrying, jet orifices atv its end. Thisl arm is angular, which. in the 'present instance is achieved by setting the tip 19 atan angle4 to the body 14, preferably 145 angle, and as-already described-itisangularly adjustable on the carriage 33. Thus, without swinging f the compound guiding structure aboutthe pivot 26, the jets may' be -caused to travel *across one side and then. another df the bar or beam, bymeans ofthe'two propelling mechanisms and the angularzadjustabilitynof the torch arm (see Figs. and 4) The operation will nowbe briefly described.
In setting upthe device, it is preferably,
though not vnecessarily, attached v.to the top flange vof any .I-beam 'or to the ball cfa rail. The -torch V1s inserted in the holder. 41 and there jet orifcebeing in advance. of the cutting jet orifice.` The holder is angularly adjusted so that the jet passages are approximately perpendicular to the top of the rail or beam. The guide 28, now horizontal, is adjusted up or down to the proper height, the torch being projected throughtheholder to the proper distance. Thecarriage 33 ismoved along the guide 28 to the st-artingposition, in this instance at the right hand side of the beam. The handle 37 is then turned topropel the jet-delivering means at.' uniform, comparatively slow speed across the topfof the beam or rail. Beforel this was done, the jets were, of course, turned on andI the heating jet lighted. The result of this first operation is to cut through the' top of the beam or rail. The whole guiding structure is now turned through an arc of 90, the nut 48 first being released, and again tightenedwhen the guide 28 is vertical.'I In this movementv the structure swings ,about 4-anh axis perpendicular to both ofthe guiding arms,'so`that the guide 28 is vert-ical and the guide 23 horizontal. The guide 28, it will be noted in Fig. 1, projects at opposite sides of the guide 23, so that the jet-delivering means may be propelled along one part while cutting the top lianges and along the other partwhile cutting the web. As the result of Swingin the g1ii=ng structure through 90 the jets are in proper angular relation to the web, and if vthe parts were properly adjusted at the beginning they are alsoat the proper at'the proper distance'from the height and v tached to a beam, rail or other bar, a member vangularly movable Von said support, a guiding vmember rectilinearly adjustable on said angularly movable member, jet-delivering means, and means for propelling the same on said guiding member at right anglesv to the direction Vof adjustment thereof. Y 10. A device of the character described, comprising'a support adapted to be attached to a beam, rail or other bar, a guide arm angularly movable on said support Vabout an axis' intermediate its ends to ocon said support through an angular dis-l i tance ,of 90, for rectilmearly guiding and propellingl said jet-delivering means, and
' means for limiting the angular movement of said mechanism and for'holding the same at either position.
Al2. A device of the' character described,
`comprising a clamp having relatively movable jaws adapted to grasp opposite edges of a beam, rail or other bar, a guide arm pivoted to one ofsaid jaws, a guide member at .right angles to and movable along 'said guide arm, acarriage mounted on said guide member, means for propelling the carriage, and a torch holderrotatably mounted thereon.
