This invention has reference to a machine for welding metallic articles, as for example, the abutting ends of iron or steel wire, although it may be found useful for welding other and various I articles either ferrous or non-ferrous.

' The various steps of welding metallic articles include the preparation of the ends of the articles to be welded; aflixing the ends of the articles to be welded, in predetermined relation to accommodate the proper and effective fusing of the,

abutting ends of such articles; welding the shutting ends of the articles by fusion through the application of heat; initially cutting or reducing burrs formed as'a result of the welding action, and finally dressing or smoothing down such burrs or enlargements at the juncture of the weld and if desirable or because of the nature of the material of the articles, annealing the same throughout the area of the weld and the area afiected thereby.

The invention has for one of its objects to improve the dies for holding the abutting ends of the articles during the means for predeterminately setting the dies for the effective welding of materials of varying gauges or sizes.

A further object of the invention is the means i or mechanism employed to initially reduce burrs or enlargements occurring as the result of the welding operation,

furthermore, to the means or mechanism for finally dressing or smoothing down the area of the welded ends of the articles to the diameter of such articles, especially if such articles should be wire or articles having the characteristics of wire.

A stiil further object of the invention is a means or mechanism for annealing the articles throughout the. area of the weld and the area affected thereby. This means is desirable, especially when welding the abutting ends of iron or steel wires which become hard and stiff, whereby to resoften the wire that it may have the same consistency throughout and be readily adapted to wire working machines of different kinds.

In the carrying out of the invention the various and several elements are combined comneatly .in a single portable machine that it may be readilyand easily moved from one place to another for use at the point of work and prefappliances whereby to erably embodies electrical weld electrically.

Other'and further objects will more fully appear from the following description,

That the invention may be more fully under- 5 stood, reference is had to the accompanying welding thereof and to thedue to the fusing action and, I

Like characters of reference denote correspond- .ingparts throughout the figures.

Frame structure 2. Connecting the-standards within the body portions is a shelf or platform 3 adapted to sup-- port elements of electrical power furnishing appliances by means of which the welding action on the articles to be welded may be accomplished by electricity.

The entire machine is designed as a portable structure and is provided with traction wheels so that it may be conveniently and easily moved from one placeto another. I, accomplish this through the provision of the pair of traction wheels 4 which are journaled on arms 5, said arms having a pivotal connection with a. common supporting bar or rod 6 supported by bearings 1 on the standards I.. Between the standards, at a suitable point, there is connected with the rod or bar 6 an angularly shaped lever bar 8 which normallyinclines upwardly, forwardly and downwardly through the frame and the longer portion of said bar, as shown in Fig. 1, has a telescopic relation in a sleeve-handle 9 which, as shown, is slotted at III for the greater portion of its length and at its forward end having the offset notch l I in which slot and notch operates a pin l2 secured to the lever bar 8, as shown. To one of the standards I is pivotally connected, at ii, the lever bar II which, together with the sleeve-handle 9 pin l2 from the notch Ii, while at the same time pulling outwardly and lifting upwardly said handle 5 into the position shown in dotted lines in Fig. 1, resulting in lifting the rear portion of the frame from off of the floor to be supported by the traction wheels as shown in Fig. 1 in which position it will be obvious that the machine can be conveniently and easily transported. Reversing the operation of the movable parts, just described, will restore the machine to the stationary Fig. 1 and the bed frame is supported a lower bed plate [5 and an upper bed plate l6 separated by a non-conductor of some suitable insulating material II. The under side face, of the lower bed plate I5, as shown in Fig. 3, is provided with an elongated open face recess I8 which, together with the upper face'of the bed frame 2, on which the lower bed plate l5 rests, provides an elongatedopen ended slot in which is reciprocally arranged the frame extension IQ of a sectionalsupport 20 to be further described. There are provided on the upper bed plate I6, as best seen in Fig. 2, the spaced bearing supports 2| and 22.

Article gripping dies and co-acting mechanisms i for gripping or clamping the ends of the articles to be welded. These dies comprise two sets, onev set including the stationary member 23 and the member 2| movable in relation thereto and the other set including the stationary member 25 and the member 26 movable in relation thereto. The set of members 23 and. 2t have a fixed position on the bed plate, except that the member 24 is movable away from and toward the member 23. The set of dies comprising the members 25 and 26 are supported so that not only can the member 26 be moved to and from the member 25, but both of said members are capable of being moved away from and toward the corresponding members 23 and'24. The members 23 and 25 have a plurality of variable size grooves, recesses'or notches 21 in their acting faces for the reception of different and selective sizes of articles to be welded and the opposing

members

26 and 26,.

respectively, have preferably smooth faces, as shown, and when moved into coaction with their respective opposite members effectively and firmtatable rod 22 and a non-rotatable shaft 29, both' of which pass through and have a bearing and longitudinal slidable relation through the spaced bearingsupports 2| and 22, respectively, and his through and by means of the rod 26 and the shaft 29,. respectively, that the support 21' with the members 25 and 26 are heldin correctalignment when moved laterally for the purpose of properly j spacing the members 25and 26 from the corre-r sponding members 23 and 26.

The movable die member 2| is connected through a reciprocal member 30, operative within a housing 3|, with a lever and cam means 32 whereby it ismade possible to move the member 26' from and toward the member 22 and although The movable die member not shown, there is a spring means within the l with the reciprocal member 33 to move and hold the member 26 ingripping relation with an anti-- cle placed between it and the member. when the lever and cam means have been moved to position to permit such spring means to act. The spring means associated with the member 24 is substantially like that shown associated with the member 26. As shown in Fig. 3, the sets of dies and their supporting means are suitably insulated from the bed plate l6. U

There is also disposed through the

supports

22 and 2|, respectively, the rod 31 which is adapted for longitudinal movement and its inner end is always in abutting relation with the support 21 and the members 25 and 25 carried thereby. The outer end of this rod 31, in addition to passing through the support 2|, also passes through and has slidable relation in 5. preferably sleeved spur gear pinion 38, the sleeve of which has a threaded relation with the support 2|, as is best seen in Fig. 3. On said rod 31 closely adjacent to the support 22 is a nut or similar member 39 between which and the face of the pinion 38 is carried a spring 4|! which is coiled about the rod3l, as shown. The rod is threaded so that the nut 39 may be adjusted to increase or decrease the normal tension in the spring 40, as will be understood. It should be apparent that when the support 2T with the members 25 and 26 are moved from the members 23 and 24, that the rod 3! will be moved outwardly, compressing the spring and placing the neces sary tension therein, so that when the fusing of the articles takes place during the welding action, this spring 49 will act to move the members 25 and 26 toward the members 23 and 24 that the proper weldingand fusing action may take place.

The rod 29 is secured at one end to the support 21 and is guided by and movable through the

supports

22 and 2|, respectively, as previously pointed out. The shaft 29 has suitable connection with the support 21', whereby to move the support-21' in one direction, that is, away from the members 23 and 24, and at its opposite or outer end said shaft passes through and has a slidablc relation in the support 2| and on its outer end has connected thereto a flanged nut or collar 4|. It will be apparent that as the support 21 with its set of die members 25 and 26 are moved away from the set of die members 23 and 24, the shaft 29 will be moved outwardly, moving the flanged nut 4| away from the support 2| and that during the fusing action and as the support 21' with the die members 25 and 26 are moved towards the die members 23 and 24, the flanged nut 4| will act as a limiting mem-, her so soon as this flanged .nut comes into abutting engagement with the support 2|.

The shaft 29 between the supports 22 and-2|, respectively, is provided with several elements, one of which is an insulation block 42 adjustably secured to said shaft and in close proximity to the support 22. Suitably spaced from this block and secured for adjustment on the-shaft 29' is an abutment block 43, and a substantial portion of the remainder. of the shaft between portion of an index nut 45. This nut has a milled may slide.

portion 49 to enable an attendant to turn it on the shaft and with a circumferentially arranged numerical die spacing index 41 and a gear portion 48 which has a meshing relation with the sleeved pinion 38. The index on the nut enables the attendant, through the operation of the nut, to predeterminately and selectively separate the set of dies 25 and 26 from the set of dies 23 and 24 the distance necessary for the proper and effective welding of the ends of the articles being welded so that there will be the required amount of material in the end of each article to provide an effectual and adequate weld.

The character of index to'beselected for the as a limitation but merely as an exemplification of the uses to which the machine may be put.

In the instant showing, the index shows that the sets of dies have been separated to accommodate the welding of wires of No. 15 gauge and that the attendant on actuating the index has separatedthe sets of dies to accommodate the machine to wires of No. 15 gauge and in doing so, when rotating the gear 48, has correspondingly rotatedthe sleeved pinion 38, but in an opposite direction. The screw threads 44 on the shaft 29 and the screw threads on the sleeved pinion 38 are such as to facilitate the outward movement of the shaft 29 and the inward move ment of the sleevedpinion 33 whereby, the latter has a sliding relation in respect to the gear 48.

the outside face of the gear 48 will bear against the support 2 I the sleeved pinion 38 being caused to move inwardly, the rod 31 being forced outwardly will automatically and predeterminately properly tension the spring 40 for effective action on the different sizes of materials to be welded. During the fusing action, and as indiexited, the shaft 29 and the indexing nut 45 will move bodily forward in unison; moving the gear 48 from the support 2|, disconnection of the gear 48 from the sleeved pinion 33 being prevented When actuating the index nut, to set the members 26 and 25 for welding,

because the latter has been moved forwardly during the setting and there is sufficient surface space on the said pinion on which the gear 48 It will be understood, that an operator may continue to weld No. 15 gauge wires,

as illustrated, without any further manipulation of the indexing device and that when welding gauges of wire other than No. 15 gauge, it will require only a simple thumbing of the indexing device to set such device to accommodate the machine to whatever gauges of wire it is desired to weld.

It will be obvious that when the indexing nut has been manipulated to predeterminately space the members 25 and 28 from the'members 23 and 24, that unless means were provided to hold the members 25 and 2G-and associated elements in such adjusted positions, they would be returned to initial starting position under the natural expansion action of the spring 40, anddifiiculty would be encountered in placing the articles to be welded in abutting relation between the sets ofmembers 23 and 24, and 25 and 26 and the members adjusted in clamping positions on said articles. To prevent this and to enable the attendant to have freedom of action in placing the articles for welding, there is provided the abutment block 43 arranged for adjustment securely on the shaft 29, see Fig.5. Arranged for coaction with said abutment block 43 is a pivotally supported stop member 49. This member is se-.v

cured on the inner end of a rockable rod 50 journaled in the bed plate l6 and also in a bearing support 5| mounted on the bed frame 2, see Figs. 4 and 5. To the outer end of said rod 50 is connetceda crank-arm 52 which has connected thereto the reciprocal rod 53 which passes down through the outer end of a lever arm 54 united in a common hub 55 from which extends a pawl or finger 56. The lower projecting end portion of the rod 53' has coiled thereabout a compensating spring 51, which bears at one end against said lever arm 54 and at its opposite end against nuts 56 adjustable on the lower end of said rod 53. Through said rod, immediately'above and in engagement with said lever arm is carried a pin 59. The pawl or finger 56 rides on a cam 66 secured to a shaft 6| which is journaled in suitable bearings in opposite walls of the bed frame 2, see Figs. 3 and 4. The cam is provided with an operator's handle 62. Immediately on the adjustment of the indexing nut 45, resulting in setting the members 25 and 26 in spaced relation to the members 23 and 24, due to the outward movement'of the shaft 29, the attendant will'see to it that the operators handle 62 is moved to its lowermost position, as seen in Figs. 1 and 4,- to insure that the stop member 49 is in engagement with the abutment member 43, see Fig. 5, to hold line position of the handle 62 in Fig. 1, which movement will partially rotate the cam Gil, mov- ,pieces of wire to be welded is of some considing the irregular face of the cam, see Fig. 4, under the pawl or finger 56 of the lever arm 54 which latter arm is caused to exert an upward thrust against the pin 59 and raise the rod 53 whereby to actuate the arm 52 to release the stop member 49 from engagement with the abutment block 43, so that when the welding action is started and fusing of thearticles takes place, the shaft 25, the indexing nut 45, the rod 28 and the support 21' are free to move bodily forward under the action of the spring 40 and the rod 31 to effect the efficient welding of the articles. The spring 5'! serves as a flexible and compensating means to take care of the variation in the travel of members 25 and 26, and associated parts, during their adjustment for different gauges of wires. The shaft 6| carrying the cam 60 and the handle 62 function additionally, as will be pointed out, to effect burr removing, as well .as

dressing and smoothing down the weld, after the welding action.

burr formed by the welding a'ction.

Cutting mechanism for preparing ends of articles to be welded To obtain an effective weld of abutting ends of metallic articles, as for example, iron or steel wire, clean and smooth ends of the wires are desirable and I accomplish this preparation of the ends of such wires by severing short ends therefrom. At or near the end of the bed frame 2, at one side and removed from the welding mechanism, see Fig. 2, I provide the cutting mechanism including a support 64 having the open ended barrel 65. In said barrel are disposed the stationary cutters 66 having a plurality of articles receiving openings 67. therecutters and the cutter 68 is oscillated that the wire will be severed in two, producing a' clean cut end for welding. The cutters are retained in operative relation with each in the barrel 65, by the removable closure 1| threaded intoone end of said barrel. By removing saidfclosure, the cutters may be removed, reinserted or others substituted therefor, as occasion may require.

Initial burr removing means and coacting mechanisms Reference has previously been made to the sectional support 20 forming a part of the reciprocally arranged frame extension II, the latter arranged and slidably movable within the elonr gated open-faced recess 3 located between the upper face of the bedjframe 2 and the lower cut-out face of the bed plate I5. The bed frame 2 is provided with the elongated slot 12 in which is slidably arranged the plate 13 secured to the frame extension IQ of said sectional support 20 and depending from this plate 13 is a roller 14 adapted to be acted upon by the cam 15 secured to the shaft 6|, the latter, as previously noted, being adapted to be oscillated by means The sectional frame 20 pro-.

of the handle 62. vides the support for the means for initially cutting burrs formed on the article welded, as a result of the welding action.

It being assumed. that one of the articles or erable length, it would be slipped down into the sectional support 20 and into coacting relation with the means for initially cutting .the To bring such a burr into position' tobe acted upon by this mechanism, the

members

24 and 26 of the sets of dies will be moved to release the article or the wire, as the case may be, which is firmly held between the sets constituting these members and when this has been done, the attendant, through and by means of pliers I6, see Fig. 2, will grip'the welded article, or the wire, as the case may be, and by a back and forth reciprocal motion causing the '-pliers, to. be alternately gripped and released, move the welded portion of the article fromthe point of welding to the point-shown in Fig. 2 and 3, preparatory to the action of the initial cutting mechanism. This plier; as such pliers are ordinarily constructed, comprises two pivoted members with gripping jaws and in this particular instance, the same Ell , erably an enlarged has lateral sliding movement on the base 11 secured to the bed frame 2, as shown. When the positioning of the Welded and burr portion of the article has been accomplished, then the article is firmly gripped in a vise comprising a. stationary section 18 and a movable section 19, the latter arranged for movement toward and from the other by means of the handle 80. This vice. as indicated in Fig. 2, is supported in a fixed position on the bed frame 2, with the exception, as noted, that it comprises a. fixed and movable section.

In further explanation of the usefulness of the mechanism being described, a welded article, as for example a wire, is designated A having formed thereon. as a result of the welding action, the burr a and this burr, as shown in Figs. 2 and 3. is in position to be acted upon by the initial burr cutting mechanism.

Referring now to the sectional support 20, it has arranged therewithin the split gear 8i within the hub of which are pivoted for coacting relation the cutting tools 82. yieldingly held for acting relation by means of springs 83. Fig. 7 shows the wire A positioned within this cutting mechanism and with the burr a ready to be acted upon by the cutting tools 82. The springs 83 yield when the article, as for example the wire, is passed down through the split portion of the gear 8! into position to be acted upon by the cutting tools and such springs further apply the force necessary for the tools to act upon the burr. Inoperation this initial burr cutting mechanism has reciprocal movement longitudinally of the article having the burr and is also rotatable whereby the projecting or ragged portions of the burr may be removed. As shown in Fig. 6. the position of the cutting tools is maintained in proper alignment with the split portion of the gear to facilitate the easy'placement of the article with its burr in position for the latter to be acted upon.

In meshing relation with the split gear Si is an operating gear 84 carried on a shaft 85 which is journaled in suitable bearings on the bed frame 2 and extends the length of said frame, To one end of this shaft is secured prefgear wheel 86 and in mesh with said gear wheel is a pinion 8T journaled on a short shaft having a bearing in a support 88 carried by the bed frame, see Figs. 2 and 3. Connected with the shaft carrying the pinion 8'3 is a crank arm 89 provided with a handle 96 whereby to impart rotatable movement to the pinion 81 and through it to the gear 88 and the shaft 85. Such rotation of this shaft 85, as will be understood, will impart rotation to the gear 84 and through it rotation to the split gear 8|.

To the opposite end of the shaft 85 is connected agear wheel 9! in meshing relation with a gear wheel 92 carried by a short counter shaft 93, suitably journaled in the bed frame 2, as shown in Figs. 4 and 6, and said gear wheel 92 is in meshing relation with a larger gear wheel 94 keyed to an elongated hub of a cam wheel 95 carried on the shaft GI, and rotatable thereon, but not rotatable thereby. In other words, free to rotate on said shaft El. This cam wheel is formed or provided with a circumferential series of successively disposed cam faces 96 and is preferably shown as being provided with a greater number of such cam faces extending 180 degrees around the cam and with a lesser number the remainder of the 180 degrees, although this is not absolutely necessary as expediency may determine otherwise. These cam faces are adapted to ride over and against a roller 91 journaled in the end of a bell crank shaped arm 98 which has a pivotal connection at one end at 99 with the bed frame, as shown. At the juncture of this bell crank shaped arm is adjustably carried a hammer I90, secured in itsadjusted position by means of the nut mi. Said hammer during its reciprocal movement as the result of the cam riding against the roller 9? will engage with a reciprocally arranged hardened steel plate Hl2, see Figs. 3 and 3, which has a slidable relation on the upper surface of the bed frame 2v and within a slotted opening provided therefor in the vise 18. This plate 102 at its opposite end, in the instant showing, bears against a hardened steel plate 103 secured to the face of the sectional support 20. In operation, the attendant, by rotating the crank arm 89, wili impart through the elements described, rotatable movement to the gear wheel 94 and the cam 95 to which it is connected and the latter will impart during such rotation reciprocal movement tothe bell crank shaped arm 83, and by a succession of blows through the hammer I00 on the plate Hi2, will impart alternate reciprocal movement to the support and through the action of the cutting tools 82, will initially and partially out the burr a preparatory to the final dressing action of parts to be described, it being understood, of cou1se,. that during such reciprocal movement of the hammer I30, the gear 86 imparts rotatable movement to the split gear 8!, as previously described. In practice it has been found that the initial cutting action, described, may

be accomplished by a one-half rotation of the" cam 95 and that the gear ratio to accomplish this, with the means shown, requires only two rotations of the crank arm 89f This need not construed as a limitation but as an expediency adapted to accomplish the results herein sought.

The hammer $00, under the action of the operative parts previously described, will impart reciprocal movement in one direction to the cutting mechanism carried by the sectional support Ell, against the action of a spring 100', which on the release of the hammer will act to return the support 20 into position to be again and successively acted upon by said hammer 100, this spring being connected at one end to the under side of the plate 13, and its opposite end to one of the standards of the support 1, as shown in Fig. 3.

Connected to the shaft 61 and adapted for reciprocation thereon is a support I04 provided with a sectional head 105 somewhat similar to the sectional support Zlland in this head is rotatably journaled a split gear wheel 1 (l6, somewhat similar to the split gear wheel 8! and within this split gear are pivotally supported in. proper alignment with the split portion of the gear, filing or dressing tools 501'. These tools function similarly to the cutting tools 82 except that the active faces of the tools I01 are designed for a dressing down action instead of a cutting action as is accomplished by the operation of the tools 82. The tools Illl are retained yieldingly in their operative positions by means of the springs Hi8 which function somewhat similarly to the springs 83. The support I04 is limited in one of its directions of movement by the block Hi9 secured to the shaft 6| and may be reciprocated away therefrom and back thereto against the spring H8 coiled about the shaft 6! and disposed between the support Illland the cam 15 so that when the support is in operative position, as will be described, and reciprocal movement is imparted thereto, in a manner to be described, it will act in one direction against the spring H and be forced back in the opposite direction by said spring.

In the normal inoperative position of the support llll it is in substantially the position shown in Figs. 1 and 6 and the radius from the shaft GI to the split portion of the gear -wheel IDS is of a distance so that when the shaft 6| is moved to raise the support I04 to bring the axis of the gear I08 into proper working position, the article on which the burr is to be dressed, as for example the wire A, will be in a position to slip into the split portion of the gear Illi, when the support N14 has been moved from a substantially hori- 'zontal to a substantially vertical position.

Assuming now that the'welding has been accomplished and the article welded moved to the position previously described for the initial cutting action on the burr a and such initial cutting action completed, the vhandle 62 connectediwith the shaft SI being in either the position shown in full lines in Fig. l or in dotted lines in the said figure, will be moved to its extreme upper position so that the latch 53' will engage in a catch III secured to the bed frame 2, as shown in Fig. 1, and in which said figure the handle 62 is shown in dotted lines moved into said upward position. On moving the handle fro'm one of its lower positions to its extreme upper position, it will cause the cam to ride against the roller and through such action move the plate I3 and the frame extension with its sectional support from the position in which it is shown in Fig. 3 to the forward position in which it is shown in Fig. 8, the reduced burr a riding between' the faces of the cutters 82 during such movement and forward adjustment of the sectional support 20. Simultaneously with this partial rotation of the shaft 6|, the support ID will be moved from the position in which it is shown in Figs. 1 and 6 to the operative position in which it is shown in Fig. 8, the article, or as the case may be, the wire A sliding into the split portion of the gear Hi6 and between the filing or dressing down tools 101 and into the position substantially shown in Fig. 8 preparatory to the action of the tools Ill! for dressing down the burr 0.. During such movement of the parts the'gear 8| moves out of mesh with the gear 8| and the gear 86, as is apparent, will move into meshing relation with said gear 84 to be actuated thereby on'the operation of the crank arm 89. To permit the placement and retraction of the support I04, the bed frame is slotted in its vertical and horizontal faces as shown at 2. To one face of the head I05 is secured a hardened steel plate I I3 having a beveled edge I I4, see Fig. 3, and this plate when the support I has been moved into operative position, rides past an end of the hardened steel plate Hi2 so as to bring the headwith its plate H3 into cooperative relation with the plate I02. The reciprocation of the support I04 on the shaft 61 is accomplished through the same hammer mechanism and parts for actuating the same as 'described in connection with the reciprocal movement imparted to the sectional support 20 carrying the cutters 82, the operative position of the parts, just described, being shown in Fig. 8, preparatory to completing the final dressing down action'of the burr. It is to be assumed that the crank arm 88 which has been rotated two revolutions in connection with the initial cutting operating of the burr is left in that position so that when the final dressing down action begins, the attendant will impart. two additional complete rotations to the crank arm 89 and cause the cam 95 to finish a complete revolution and in so doing impart a series of short reciprocal movements to the support Ill and through the action of the tools Ill'l file the burr smoothly down to the diameter of the article, assuming that the article is a wire; .By reference to Fig.-l0, it will be seen that the face of the cam 95- has a series of, long and comparatively slow successively acting cam faces on the right hand side arranged throughout I88 degrees of its surface and that on the remainder of the I80 degrees of surface there are a greater number of cam faces, whereby to produce the series of short and quickly successive reciprocations of the support I04. It is of course understood that in the instant showing the cutting and filing actions produced by the cam are accomplished through one complete rotation of the cam 96 and that while I have elected to show an arrangement of cam faces, long on one side and short on the other, these faces may be rearranged and provided in such order as expediency may suggest or require. Furthermore, the gear ratio'shown may be-rearranged to accommodate any changes which may be made in the cam.

In Fig. 11, there is diagrammatically shown ,the several steps from the initial preparation of the article to its finish, including the step of cutting the ends of the sections of the article to be welded; the welding action when the articles are brought into abutting relation; the welded article with the resultant burr a; the burr having been initially treated, preparatory to being filed and smoothed down, and the final article as it would appear after the complete dressing down action by the tools I01.

Power sourceand appliances for welding I have elected to show a mode of electrical heating for the welding action, but since no claim is to be made on the electrical heating or its equipment, it will not be necessary to describe more than a simple means for accomplishing this purpose.

The current generated by the electrical equipment is designed to pass through one set of dies, the article to be welded and out through .the other set of dies as is customary in machines of this character. In Figs. 1, 3 and 4, I have shown connected with one set of dies buss bars B and to the other set of dies buss bars C. Both sets of bars are connected to a transformer D supported v by the rest or platform 3 and said transformer is suitably connected with a magnetic switch E also supported by said platform ,or rest 3 and the magnetic switch E is connected with a switch box F secured to a' sideof the bed frame 2 and c the welding action, the attendant will push the starting button I, as will be understood, and during any emergency, while the current is on, he can shut off the current by the operation of the stop button I. r I

I have provided means for automatically actuating the electrical switch for cutting off the by the operation of welding comprising a rotatcurrent immediately on the completion of the welding action. This means is best seen in Figs. 2 and 2. Connected with the fixed support 22 is a block I of suitable nonconducting material which carries terminals 1' and i as shown in Fig. 2 and also a switch plate J having a permanent connection with the terminal 2" and arranged for a breaking and contact relation with the terminal 1', as shown. Arranged for operation through the block I is a pin K which is secured at one end to the block 42 and adapted during the movement of said block with the shaft 28 to engage and move the plate J, whereby to break the contact between said plate and the terminal 2', resulting in shutting off the current on the completion of the weld. Conductors, as will be understood, lead from the terminals 1 and i to a proper electrical power source, not shown.

7 welding of the metallic articles, there is usually found a spot a short distance away from the weld where there is a sharp line of demarkation between the high heat zone and the unaffected part or parts of the article or articles so that there is either a very coarse crystalline structure at this point or there is a sharp gradation between the grain size, but whatever it is there is a very brittle spot atthe point of welding on both sides of the weld. It may be that this is due to a very severe grain distortion of some kind. In any event, when the metallic article is heated up to an annealing temperature, this structure readjusts itself and the brittle spot is completely removed. I have, therefore, designed in connection with this machine, a means for annealing the welded article, preferably after the dressing down action of the burr, although it may be found desirable to use it at any time following the welding action. This means comprises, as shown in Figs. 2, 3 and 4, two sets of cooperating jaws i I5 and l l5, respectively, in association with the sets of dies, one set of jaws being also associated with buss bars B and the other set being associated with the buss bars C. In each instance the jaw HE has a pivotal relation at H? with its jaw lid and normally held in closed relation by means of a spring lid which, while it holds the jaws in closed relation, will permit the jaws to be open for the placement of the welded article therebetween, as shown in Figs. 3 and 11 (j) the mode of heating the annealing jaws being controlled through the actuation of the starting and stopping buttons of the switch box previously described.
