9 Claims.
The present invention relates to weldrod holders, and has for its object to provide a holder in which the weldrod may be quickly inserted and firmly held, and in which the stub of the weldrod, after the rod has been consumed in the welding operation, may be automatically ejected from the holder. Further, the construction is such that the holder is completely insulated; the power lead is protected against displacement or injury, and the weldrod mounting is such that the rod is firmly held without danger of displacemerit until such time as it is desired to eject the stub.'
In the drawings herewith I have illustrated one form 01' my invention, and this the best now known to me, but the disclosure is illustrative skid in no sense restrictive, as variations in mechanical make-up can be made from the particular arrangement here shown.
In the drawings:
Figure 1 is a longitudinal sectional view of the holder with a weldrod in place and the ejector in retracted position. I
Figure 2 is a view similar to Figure l with the ejector projected in position after the stub has been ejected..
Figure 3 is a sectional view substantially on the line 3-4 of Figure 1, looking in the direction of the arrow.
Figure 4 is a sectional view on substantially the line 4-4 of Figure 1, looking in the direction of the arrow.
Figure 5 is a longitudinal sectional view 01' the rod holding section.
Figure 6 is a plan view of the rod holding section, parts being broken away for cleamess of illustration.
Figure 7 is a vertical sectional view of the rod holding clamp.
Figure 8 is a view of the rod holding clamp in side elevation.
Figure 9 is a sectional view to show the clamping of a weldrod of smaller dimensions in the holder. I
Referring to the drawings by numbers, like numbers indicating like parts in the several views, III indicates a housing of any suitable inchambered end of the member I I, although other suitable means of securing the power lead may be adopted so long as a good connection is secured.
The insulating housing III has its ends extended beyond the ends of the weldrod holding member II, so as to protect the power lead connection and guard against any contact at either end of the device with the power lead or the charged rod holder and avoid short circuitin and injury to the operator.
The rod holding member is made up of the section II which may be secured to the insulated housing III in any suitable manner, a screw con-' press fit or other suitable coupling may be made.
The section I3 forms a mounting for the rod and such mounting is here shown as a longitudinally disposed recess, circular in cross section, and of a diameter which will take full diameter and smaller rods. The mounting is such that it receives the end of a rod and holds it in longitudinal alignment with the tool.
Housed within the section II in rear.of the section I3 is the ejector I4 having a chambered rear portion I5 to receive the ejector spring I6, the rear end of which abuts a partition H in the section II, the spring I6 tending to force the ejector outwardly into section I3. The ejector I4 is provided with a forward portion I9 of smaller diameter which is aligned with and tits the bore of the section I3, here shown as circular in cross section, although it may take other cross-sectional shapes, ii. desired. The shoulder between the portions I4 and I 8 of the ejector abuts the rear'end of the section I3 which limits forward movement of the ejector.
Transversely of the holder at its forward end is a gripper member 20 which passes through an opening in the housing I0, and through registering openings in the section I I and the section I3, the lower end of the gripper engaging a socket in the wall of the insulating housing Ill. The gripper 20 is normally urged outwardly by a spring 2i mounted in the chambered lower end of the gripper member 20 and the socket in the insulating housing ill, the spring 2| tending normally to hold the gripper member in the position shown in Figure 1. A pin and slot connection 22 is provided to hold the gripper 20 in place and the upper end of the gripper, which projects beyond housing i0, is provided with an insulating cap 23 for manual manipulation, which extends inwardly of the housing l0, so as to surely insulate against escape of current from and short circuiting of the holder.
The section I 3, as stated, is provided with a recess which forms a mounting to receive a weldrod, and in order to grip the weldrod surely in its mounting I preferably provide the wall of section l3 with a frictional rod gripping surface, here shown as a groove 24. The gripping face of the gripper 20 is provided with an opposing groove 25. These rod-engaging surfaces, here shown as grooves, hold the weldrod against twisting or displacement and are particularly useful where the weldrod is of less diameter than the circular recess in the section I: as illustrated in Figure 9.
The gripper 20 is provided with an opening 20 which registers with the opening in the section l3, so that when the gripper is depressed, a weldrod may be inserted, forcing the ejector ll back against the action of the spring [6. When the gripper is released, the spring 2!, exerting its outward pressure, will grip the rod securely between its lower face and the upper face of the recess in the section l3, and hold the parts in the position shown in Figure 1 with the ejector in retracted position.
The construction disclosed is simple and easy of manufacture and assembly. The member ii and the power lead can be readily assembled, the ejector l4 and its spring i 8 inserted in the chamber in the holder, and the forward section I! of the holder can then be secured in place, holding the ejector H in its chamber. The gripper 20, with its spring 2!, can then be mounted transversely; the cross pin for the pin and slot connection 22 inserted, and the parts are in assembled and operative position. The holder thus assembled can then be entered into the housing and secured in place by the fastening means, such as the screw l2 or its equivalent, and when thus fastened the opening in the housing l and in the holder sections ii and ii are in registry.
In operation the weldrod will be thrust into the recess in the section l3, forcing the ejector rearwardly against the spring It, the gripper i being manually held in its inward position against the action of spring H to permit this action. Upon release of the gripper the spring will move the gripper outwardly, the weldrod will be gripped and securely held, and the ejector l4 restrained in its chamber. When the weldrod has been consumed, or if for any other reason it is desired to remove it, the operator will press down on the insulated top 23 of the gripper 20, releasing the weldrod, and immediately the portion I! of the ejector I will, under the influence of the spring l6, be thrust forwardly through the recess in the section i3, and through the opening in the gripper 20, ejecting the rod or the stub from the holder.
Such changes from the disclosure here made as are within the range of mechanical skill and the scope of the appended claims are to be regarded as within the purview of my invention.
