' can walk alongside of the bloom or billet to propel the carriage therealong.
Another object is to provide hangers and cradles for the scarfing torches and means for adjusting the same.
An additional object is to provide a back-rest which, in coaction with the guiding rolls on the carriage, positions the scarring torches at various desired oblique angles with respect to the bloom or billet.
Another object is to provide a starting rod adapted to cooperate with the torches in initiating the .scarflng operation and in the provision of control means operable from a point readily accessible to the operator for controlling the release of the starting rod.
The above and related features of the invention will be more fully apparent from a consideration of the following detailed disclosure, the accompanying drawings, and the appended claims. I
In the drawings:
Figure 1 is a side elevation of billet scarflng apparatus embodying the herein claimed invention.
Figure 2 is a projection perpendicular to Figure 1 (on line II--II).
Figure 3 is a vertical section on line III-III of Figure 2. I
Figure 4 is a traverse section on line IV-IV of Figure 1, illustrating the means for adjusting the flanged guide'wheels of the carriage for guiding coaction with different widths of billets.
Figure 5 is a transverse section on line VV of Figure 3. illustrating the torch-supporting cradles and details of related parts coacting therewith. 4
Referring in detail to the drawings, reference letter B represents a bloom or billet whose 'upper face b is adapted to be scarfed by means of a plurality of torches Ill hung from a carriage indicated as a whole at =l2. The carriage comprises side frame members l4-I4 and a laterally offset 4 Claims. (Cl. 266-23) portion It to which is secured a handle rod l8 having a transversely-extending handle bar 20 secured at the upper end thereof. I The side frame members l4l4 are held in spaced relation by an intermediate transverse member 22 and a rear transverse member 24. At its forward end one of the members I4 is offset inwardly, as indicated at I4 in Figure 2. Bridging the space between this member I4 and the member i4 opposite thereto is a sleeve 26 serving as a guide for a bar 28 having a rack 30 secured thereto. A pinion 32 is supported by a stub shaft 34 mounted in suitable bearings 36. The upper end of the stub shaft is squared as indicated at 38, for coaction with a socket wrench or the like by means of which the rack 30 can be reciprocated transversely.
Depending from one end of the sleeve 26 or from any other relatively fixed part of the forward end of the frame I4 is a bracket having a bent extremity 42 carrying a trunnion pin 44 which rotatably supports a flanged wheel 46. The
' rack bar 28 carries a bracket 48 having an inwardly bent end 50 carrying a trunnion 52 which rotatably supports a flanged wheel 54. flanged wheels 46 and 54, as shown and described, are mounted ontrunnions whose axes are oblique to the upper face of the billet to be scarfed, and by manipulation of the pinion 32 it will be understood that one of the flanged wheels can be adjusted with respect to the other, so as to shift the wheel 54, for example, from the full-line position of Figure 4 to the dotted-line position of the same figure, thus adapting the wheels of the carriage for guiding coaction with the upper corners of the billets of diflerent widths to be scarfed.
Depending from the rear of the carriage is a portion 56 carrying a bracket 58 having a back rest rod 60 'slidable therein and adapted to be secured 'in the. desired position of adjustment by clamp screw 62, the rod having a foot 64 arranged for sliding engagement with the upper surface of the billet to be scarfed. It will be understood that the wheels 46 and 54, in coaction with the backrest 60, are effective to support the scarflng torches ill at any desired oblique angle with respect to the upper face of the billet.
.To start a scarring operation on a bloom or billet, it is desirable to first melt the end 01 a starting rod such as indicated at 68. To this end I secure a bracket 68 to a nozzle Ill of one of the scarflng torches. This starting rod is supported in a position substantially perpendicular to the billet to be scarred, the rod sliding freely through registering openings 12 formed in portions of the bracket 8 as shown in Figure 3.
The.
in a bracket 82 secured to the rear cross member 24 of the carriage. An operating finger ring 80 is secured to the rear extremity of the link 10, this ring being at a location within the convenient reach of the operator. Thus after the lower extremity of the starting rod 06 has been burned away in initiating the scarflng operation, when it is desired to again initiate scarfing on another billet or on a different portion of the billet, it is merely necessary for the operator to pull on the finger ring 84 so that the clutch spring 16 will be released and cause a new length of rod to come into contact at its lower end with the face of the new billet or new portion of the billet to be acted upon.
In the apparatus illustrated, improved means are provided for laterally adjusting the scarfing torches individually with respect to one another, and collectively with relation to their supporting carriage. This improved supporting means includes cradles 86, there being one set of cradles 06 supporting the lower portions of the torches and another set of identical cradles supporting the upper portions of the torches, as indicated in Figure 3. Thus a description of one of the cradles and its supporting and adjusting means will suffice for all.
Each torch carries a collar 88 equipped with a clamp screw 90, and each torch has a depending lug 92 which is connected by a spring 94 anchored to one of the upper cradles, as indicated at 96. Thus the springs tend to move the torches downwardly toward the work. By a manipulation of the clamp screw 90 of the collar 88, the proximity of the nozzle at the lower end of the torch with respect to the billet to be scarfed can be readily adjusted. The torch cradles are hung from screw shafts 9B which pass freely through openings therein, and associated with each cradle there is a knurled adjusting nut I by means of which any given cradle torch can be laterally adjusted individually with respect to its neighbors. Each screw shaft 98 is rotatably supported near its ends in hangers I02 which are slidably mounted in guides I04 carried by the side frame members of the carriage. An adjusting screw I06 having a squared portion at its upper extremity for coaction with a suitable wrench, is threaded through an extension I08 formed on each hanger so as to provide for the adjustment of each cradle toward or from the billet.
Extending parallel to each screw shaft 98 and also rotatably supported by the hangers I02 is a bar IIO having rack teeth H2 meshing with a coacting pinion II L. Each bar H0 is formed with a groove III for guiding engagement with a tongue I I3 extending from each cradle 86. The screw shaft 98 and bar H0 at their ends are rotatably mounted in respective plates H6. The pinions H4 are confined in housings H8 which are adapted to partake of the adjustment of the hangers I02. The shaft on which each pinion H4 is mounted is connected by a universal joint I20 which is connected by a reach rod I22 with a similar universal joint I24 including a shaft portion I26 to which is secured a crank I28 within easy reach of the operator. As thus arranged it will be 'apparentjhat by turning a respective crank I28, the operator can reciprocate the rack bar 0 so as to thus collectively shift either the forward portion or the rear portion, or in fact both portions of the torches, so as to thus vary the angularity of the torches with respect to the longitudinal center line of the billet. Thus the angularity of flame impingement is made variable.
Th s adjustment also provides for collectively positioning the torches for coaction with selected portions of the face of the billet to be scarred. This collective adjustment. when taken with the individual adjustment of the torches relatively to one another by manipulation of the knurled nuts I00, provides for precision adjustment and enables the user to set the apparatus quickly and easily and with a great degree of accuracy, to suit the requirements of the particular billets to be scarfed.
The torches I 0 are connected by flexible tubing to suitable sources of fuel and comburent such as acetylene gas and oxygen. The scarfing torches per se are of known conventional construction.
- Such torches are equipped with a means for opening and closing the gas passage and a similar means for opening and closing the oxygen passage (not shown on the drawing). During the scarfing operation it becomes necessary to increase the amount of oxygen to bring about oxidation of the metal being scarred; therefore it is necessary to provide a suitable means for controlling the oxygen supply. In Figure 1 I have shown such a high pressure control valve in the form of a lever I30 pivoted at I32 and equipped with a spring I34. For actuating such valve levers I provide a universal bar I35 common to all torches, "this bar being connected at its ends to arms I36 or bell crank levers I38. One lever I38 is connected by a link I40 with an operating knob I42 located in a position readily accessible to the operator. In the case illustrated the fuel control knob I02 is conveniently mounted on a bracket I44 secured to the handle bar 20.
From the foregoing description it is manifest that the improved apparatus illustrated provides means for attainment of the objects of the invention enumerated in the opening paragraphs of this specification.
While I have described quite precisely a preferred construction of highly desirable cooperating instrumentalities, it is not to be construed that I am limited thereto, since.various modifications and substitutions of equivalents may be resorted to by those skilled in the art without departure from the invention as defined in the appended claims.
I claim:
