'Application filed April 20, 1922. Serial No. 555,759.

To aZZ whom t may concern:

Be it known that I, CHRISTIAN S. ANDER-- State of Illinois, have inventedv a new land useful Work Support, of which the following a specification. Y

The device formingthe subject matter of this application is a work support, adapted to hold two pieces of material whilst the Recalling that severed pieces of metalV which are to be welded may be of almost any shape or size, the objects of this invention may be summed up in the brief statement that the machine hereinafter described is so constructedthat a large number of adjustments are possibleto the end that thepieces of material may be brought together properly, for welding.

It is withinthe province of the disclosure to improve generally and toenhance the utility of devices of that type to which the4 invention appertains.

Vith the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention lshown can be made without departing from the spirit of the invention. i

In the accompanying drawings Figure 1 shows in elevation, a* devicekconstructed in` accordance with the invention, parts being broken away; Figure 2 is an elevation wherein the device is viewed at right angles to the showing of Figure 1, parts being in section; Figure 3 is a section on the 3 3 of Figure 1; Figure 4 is a section on the line 4-4 of Figure 1*; Figure 5 is a section on the 'line 5-5 of Figure 1.

The work ,support forming the subject matter of'this application comprises a frame, which is denoted generally by the numeral 1, the frame embodying a. base plate 2carrying an upwardly projecting standard 3 having a longitudinal slot 4, the standardbeing supplied at its upper end with a transverse bearing 5 carrying a 'cup 6 adapted to contain flux of any other substance used in welding. A hollow shaft 7 is rotatable in the bearing 5 and is provided intermediate itsends with a toothed keeper wheel 8. At

one end, the shaft 7 has a Vfork 9 wherein is disposed toothed keeper 10 located at'right angles to the keeper 8, the keeper .10 being rotatably mounted on .the fork'v 9' as 'indil cated'at 11. An annularguide'12 is disposed in the hollow shaft 7 and is held therein by securing elements 14-(Figure fA i first latch, in the form of a pin `15,`is mount-` i ed forright line reciprocationl in the guide 12 and in the remote end ofthef hollow shaftl Y 7. The latch 'pin 15 is advanced by a compression spring 17, to engage with the keeper 10 through the instrumentality of the compressionspring`17, located within the shaft 7, one end of thespring engaging theguide 12and the other end of thel spring engaging an abutment 16 on the latch pin. At its outer end, the pin 15 is ysupplied with a head 'i i l 18 engagedib'y a forkV 19 on Vthe upper end of anangular lever 20, the lever beingl eX-l tendedinto the slot 4 of the standard 3 and being fulcrumed intermediate itsends on'. the standard as shown 4at 21. A Vsecondy .latch 22 is provided andprojects into the* slot 4l of the standard 3, the latch 22 being fulcrumed intermediate its ends on the standard, as shown at 23; The innerendof the latch 22 extendsbeneathr thek inner end of the lever 2O as clearly shown in Figureal. A lever orfpedal 24 projects into the slot 4 of the standard 34 and is fulcrumedl at its y inner end as' at 25 on the standard. A connection 26'is pivoted at its upper end to the second latchr 22, and is pivoted at its end tothe lever or pedal 24.

A first arm 27 .is mounted lower rigidly 'on the toothed keeper 1() and extendsgtran'sversely' thereof, thejarm 27 having a longitudinal guide slot 28. At one end, the arm27 yis equipped with a transversel head 29-'having an elongated guide slot-30, disposed at right angles to the-slot 28 in the arm 27. Threaded openingsv 31 and 32 are `fashioned in the ends of the head 29 and into either of these screw 36 being rotatable Vin the'slide, the

clamping screw having a turningv head 37. I

The clamping screw 36 is threaded into apost 38 forming part o f a vvork holder-denoted generally by the numeral 39 in Figure 2, the screw serving to clamp the post on the head The post 38 has aprojecting fixed .jaw 40, and is provided with an arm 4l located parallel to the said jaw. The movable jaw 42 cooperates with the fixed jaw 40 and Vis adapted to move on the arm 4l, transversely of the post 38. A screw 43 is threaded into the movable jaw 42 and is held for rotation, but against longitudinal movement in the post 38, by means of an abutment 44 and a handle 45 on the screw.

Asecond arm` 46 is superposed on the first arm 27 and is provided with a longitudinal guide slot 47 The niuneral 48 in Figure 2 designates, generally, a clamp, holding the j arms 46 and 27 together for relative longitudinal movement and for pivotal movement with respect to each other. The clamp 48 embodies a slide 49 mounted tor adjustment in the slot 28 oi* the first arm 27 and ext-ended, beneath the said arm. A screw 50 eX- tends downwardly through the slot 47 in the second arm 46 and is threaded into the slide 49, the screw 50 being supplied with a head 5l adapted to engage the second arm 46.

At its outer end, the second arm 46 is equipped with a socket 52 placed at right angles to the said arm.. A hollow post 53 is a turning head 61.

located in the socket 52. rlhe post 53 may be rotated in the socket 52, or it may be moved longitudinally therein. A set screw 54,Y provided with a turning head 55 is threaded into the socket 52 and engages the post 53 to hold the same in adjusted positions. A tubular slide 56 surrounds the post 53. The slide 56 may be rotated on the post, or it may be adjusted longitudinally of the post.- The slide 56 is moved longitudinally of the post 53 by means of an adjusting screw 57, threaded into the end of the post 53. and held against rotation in one end of the slide 56 by means of an abutment 58 and a turning head 59 on the screw. The slide 56 may be held securely on the post 53, in any position in which the slide may have been adjusted, by a clamp screwv 60 threaded into the slide 56 and provided with The tub-ular slide 56 is provided with a transversely extended oli'set socket 62 wherein a hollow slide 63 is mounted tor right line reciprocation. rlhe slide 63 is moved endwise by a screw 64 threaded into the inner end of the slide, the screw being held fory rotation in one end of the socket 62 through the instrumentality ot an: abutment 65 and a turning head 66 on the screw.

lA screw 67 is threaded into the socket 62 Maasai supplied at one end with a fixed jaw 71 and equipped at its other end with a clamp screw 72 adapted to cooperate with the fixed jaw. A stem 73 projects trom the yoke 70 int-erniediate the ends thereof, and terminates in a ball 74 received in a socket 75 (Figure 3) formed in the outer end of the slide 63. A retainer 76 is threaded on the end of the slide 63 and cooperates with the ball 74 to hold the work grip 69 movably on the slide 63. The work grip 69 is held automatically in any position to which it may have been adjusted, because the ball 74 of the work grip is engaged by the hollow head 77 of a clamp 78 slidable in a partition 79 formed in the slide 63, and advanced, to press the head 7 7 against. the ball 74, by means ot a compression spring 80, one end of the compression spring engaging the head 77, and the other end of the compression spring engaging the partition 79. A releasing lever 82 constitutes means for retracting the clamp rod 78 against the action ot' the spring 80, thereby setting the work grip 69 free for adjustment. The releasing lever 82 is engaged at one end in an opening 8l formed in the inner end ot the clamp rod 78, the lever extending outwardly, through a slot 83 in the slide 63, the lever being supported intermediate its ends on a tulcrum pin 84 carried by the slide.

Supposing that two pieces ot metal are to be welded together, one piece is held between the screw 72 and the jaw 7l of the work grip 69, whereas the other piece is held tween the jaws 40 and 42 of the work holder 39, the work holder 39 being carried by the first arm 27, and the work grip 69 being carried indirectly, by the second arm 46. y

Two classes of adjustments are possible in the machine. @ne of these classes relates to the adjustment of the two pieces of work with respect to each other, and the other class of adjustments relates to the movement ot the two pieces of work, after they have been brought together, with respect to the operator, although in practice, these two classes or' adjustments may, overlap each other, so far as function is concerned, First, the adjustments which enable the two pieces of work to be brought together will be described and, secondly, the adjustments of the work relative to the operator will be set forth. Y

Referring to the adjustments ot' the two pieces of work with respect to each other, to enable them to be brought together, it may be stated that the post 38 of the work holder 39 may be moved longitudinally of the head 29-and transversely of the arm 27 by loosening the clamping screw 36;,the 'slide 35,fand consequently the post 38 being retained in adjusted positions, longitudinally of the head' 29 by the screw 331 The post 38, further, may be rotated on the screw 36 before j movement being imparted to the slide by the the latter is tightened up, The work holder 39 of which the post 38 constitutes a part, is therefore, 4rotatable with respect to the arm 27, and is adjustable transversely of the said arm." The arms 27 and 46 may be adjusted longitudinally with respect to each other, thereby to vary the space between the work grip 69 and the work holder 59 and the said arms may be disposed at different angles with respect to each other, the clamp 43k permitting the'arms 46 and 27 to be adjusted as aforesaid.l If the screw 54 is loosened, the post 53 may be adjusted in the direction of its axis in the socket 52 on the arm 46 and the post, further may be rotated in the sock' et. When the clamp 60 is released, the slide 56 may be rotated on the post 53. The slide, further, may vbe moved longitudinally of the post 53 through the instrumentality of the adjustingscrew 57. The slide 63 may be moved lengthwise in the socket 62,

adjusting screw 64. When the clamp rod 78 is retracted through the working of the releasing lever 82, the ballv 7 4 can rock in the lsocket 7 of the slide 63, and the work: grip 69 may be disposed in a wide variety of different positions.

Passing to those adjustments which relate to the disposition ofthe work with respect to the operator, the pedal 24 may be depressed, motion being transmitted to the latch 22 by way of the connection 26, the latch 22 being disengaged from the keeper wheel 8. The latch 22 tilts the lever 20 on its fulcrum 2l, the forkl9vof the lever retracts the latch pin l5 out'ofengagement with the keeper l0 and, then, the hollow shaft 7 may be rotated in the beading 5 permitting the assembled pieces of work, carried by the holder 39 and the grip 69 to be turned upside-down orbe disposedin many other positions about the axis of rotation of the shaft 7. Recalling that the latch pin l5 is out of engagement with the keeper 10, the keeper l0 may be swung on its pivotal mounting ll, the arm 26 moving with the keeper l() and the arm 46 moving with the arm 26. The work, therefore may beswung in opposite directions, with the element 1l as a'center, in opposite directions, as shown by the arrows A in Figure l and, since the shaft 7 is rotatable in the bearing 5, therwork may be swung in opposite directions,.with the axis of the shaft 7 as a center, as indicated by the arrows B in Figure'2.

'The foregoing will render it evident that two pieces of work may be brought together forrwelding in a wide variety of ways, it being possible to shift the two pieces of-work, with respect to the operator, after they have been brought together, into many different positions.
