SPECIFICATION forming part 01 Letters Patent No. 758,797, dated May 3, 1904.
Application filed March 4,1903. Serial No. 146,100- (No model.)
T (11/ who/'11 it may con/warn.-
Be it known that I, Fmcnnmox F. Tune, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful \Velding- Tool, of which the following is a specification.
Hy invention relates to improvements in welding-tools which are used in connection with steam hammers or other mechanism where the necessary blow can be obtained; and it consists of a tool having a lower stationary head and an upper movable head, the upper head being guided in its movement by pins or rods secured in the lower head and held normally at some distance above the lower head by springs or some similar devices. Each of the said heads is provided with means for attaching thereto one of a pair of cooperating dies or molds.
The object of my improvement is to provide a tool which will hold two cooperating dies or molds normally apart a sufficient distance to enable the introduction of heated work between them and at the same time guide the dies in their movement to have them meet properly and accurately when suddenly forced together. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is a perspective view of an ordinary steam-hammer, showing my invention in connection therewith. Fig. 2 is a plan view of the welding-tool removed from the steam-immmer. Fig. 3 is a front elevation of the same. Fig. AI is a section on 4 I of Fig. 2. Fig. 5 is a section on 5 5 of Fig. 3. Fig. 6 is a bottom plan of an uper die. Fig. 7 is a top plan of a lower die to cooperate therewith, and Fig. 8 is a perspective of a welded connection formed by the dies shown in Figs. 6 and 7.
Similar reference characters refer to identical parts throughout the several views.
I have shown my device in connection with a steam-hammer 10, but it can be used with any suitable machine or device.
11 is the upper movable hammer-head, and 12 is the stationary anvil.
Referring to the welding-tool proper, 13 is the lower stationary head, having the side down\vardly-projecting flanges 14, the pin 15 extending a short distance down from its under face and the four pins 16 extending upward from its upper face. This lower head 13 also has in its upper face the dovetailed recess 17 and a pin 18, extending upward from its flat face. The upper movable head 19 is provided with the four holes 20, through which the pins 16 pass. The head 19 has on its upper side the striking extension 21 and in the lower side the dovetailed recess 22, which corresponds to the recess 17 in the head 13. A pin 22 projects downward from the face of the recess 22. The coil expandingsprings 23 are interposed between the heads 13 and 19, preferably around the pins 16, to keep the upper head 19 normally some distance from the head 13. The pins 16 are provided with heads 2a to prevent the head 19 being raised too high.
The device which has thus far been described substantially constitutes my invention; but to more clearly show the object and operation of the same I hzwe shown a set of dies in connection therewith and will describe the operation of my device with the dies and the product of those particular dies. It is understood that the dies are removable, and any shape or form of dies may be used. The lower die 25 is secured to the lower stationary head 13, preferably by a key 26 in the recess 17, the pin 18 registering with the recess 27 in the lower side of the die The die 25 has on its upper side the recessed matrix or mold 28. The upper die 29 is secured to the upper movable head 19, preferably by a key 30 in the recess 22 the pin 22 registering with the recess 31 in the upper side of the die 29. The die 29 has on its lower surface the recessed matrix or mold 32, made to cooperate with the die 25 to form the desired welded joint.
In operation my device is used in connection with a steam-hammer of the type shown by setting the head 13 on the anvil 12 to have the pin 15 register with the hole 33 in the top of the anvil 12 and the flanges 14 on either side of said anvil. The desired dies are then inserted into the recesses 17 and 22, being held lirml y by driving the keys 26 and 30 into i position. The dies shown in the drawings are ISO for the purpose of welding a round bar to a flat bar, which when complete appears as shown in'Fig. 8. The one end of the round bar and one end of the flat bar are lapped over each other the required distance between the two dies while in the proper heated condition, and the hammer-:head 11 is brought down upon the head 19 with the necessary force by the operator to weld the two ends together and at the same time press the welded joint into the dies, thus making any desired shape or? weld or even shape a bar without a weld, the object being to accomplish the operation as speedily as possible. The springs 23 always.- raise the upper die when the hammerhead is raised.
I may provide the shearing-blades 34 on the side of the heads 13 and 19, which are arranged to shear off round bars when a blow from the hammer-head is delivered on the movable head 19.
I wish it to be understood that I do not limit myself to the exact construction shown any more than is necessary by the prior state of the art.
What I claim, and desire to'secure by Letters Patent, is-
In a welding-tooLa die-holding mechanism comprising two die-holding blocks, guides for one block secured to the other block and a spring to normally hold the blocks separated, and means to hold said die-holding mechanism in proper position, said means comprising two flanges resting against the sides of a base and a pin. extending into a hole in said base substantially as specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
