HENRY E. RARICK, OF ALTOONA, PENNSYLVANIA.
STOVING-I-IAMMER.
Application filed October 25, 1916.
To all whom it may concern:
Be it known that I, HENRY E. RARIGK, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Stoving-Hammers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to machines for stoving locomotive frames or other heavy iron preparatory to welding. Its object is to provide a ram or hammer which may be mechanically operated as, for example, by a steam-hammer or equivalent means. To this end it comprises the novel parts and combinations recited in the appended claims.
In the drawings Figure 1 is a side elevation;
Fig. 2 is a plan view;
Fig. 3 is a detail View of the ram or hammer;
and Fig. 4 is a detail view of the pressure bar through which the initial force is applied to operate the hammer.
In the preferred form of my invention, illustrated in the drawings, 10 represents a hammer die operated by steam or other power and 11 represents a bottom hammer die or anvil.
12 is a clamping plate adapted to fit the top of the anvil 11 and having for convenience of application substantially the form illustrated, comprising a hook-shaped arm slotted to receive a pin of the customary form passing into a recess in the anvil, the parts as so arranged providing'an oblong passage through which the customary pin may be driven to enable the easy handling of the anvil.
13 and 14 represent two plates bolted to gether as indicated. At one end, each of these frames or plates has secured to it by the bolts which hold the plates together additional plates 15 and 16 which extend above the frame-plates and which serve to limit the operation of the steam-hammer, as indicated. At the opposite end of the frame are secured two arms 17 and 18. In the illustrated form, these arms are pivoted at 19, so that the arms may be turned up out of the way, but in use they lie in the position indicated, shoulders 20 and 21 upon Specification of Letters Patent.
Patented Apr. 24, 1917.
Serial No. 127,595.
The ram or hammer is shown at 25. It
has an enlarged head 26 lying beyond the plates 15 and 16, thus limiting the forward stroke of the hammer.
Within the plates 15 and 16 are j ournale two rollers 27 and 28 to guide the rear end of the hammer. The hammer is enlarged at one end beyond the point 29, and this part of the hammer runs upon a roller 30. The forward or operating end of the hammer passes under a sleeve turning on the pivot rod 19 which provides additional guiding means, and finally projects through an opening in the guide plate 24 when it is thrown forward against the work.
It will be observed that the hammer is arranged at an inclination, the thicker part resting on the roller 30. This provides for the automatic return by gravity of the hammer after it has given its blow forward or to the right as indicated in the drawing.
A pressure bar 31 is pivoted to the shaft which carries the roller 28, and is forked at the forward end, as clearly shown in Fig. 4. The forked end has two journal recesses to receive the shaft of a roller 32, and at its forward end is perforated to receive the pivot shaft of a link 33, which, in turn, is pivoted to the short end of an elbow lever 34 pivoted to a bolt between standards 35 projecting upward from the plates 13 and 14. The elbow lever 34 has its long end pivoted to a link 36, which is pivoted to a boss 37- on the plunger 25.
' In operation, the work to be treated is placed on the plate 22 and the steam-hammer 10 is then brought down until it reaches the roller 32. It will be understood that in the illustration the roller is shown in its depressed position, and that if the steamhammer were lifted and the parts permitted to return to initial position the roller 32 would be elevated above the top of the plates 15 and 16. When the steam-hammer presses on this roller it will carry it down to the position illustrated in Fig. 1, for example. The effect will be to press down the pressure arm 31 and through the connectionsthe link 33, the elbow lever 34 and the link 36t0 swing the hammer 25 forward, imparting a powerful blow against the point to be operated upon. WVhen the steam-hammer is lifted, gravity will carry the ram or hammer 25, running upon the rollers 30 and 27, and all the parts will resume the original positions they had before the operation of the steam-hammer, the stroke to be repeated as often as required to produce the desired result.
It is not necessary to illustrate the effect of the blow, but in Fig. 1 I have indicated the spreading effect upon the projecting end of the frame piece or work to be treated. It will be understood that in preparation for welding such frames it is necessary to scarf the point to be welded and this is done by the stoving operation of my ram or hammer.
I claim '1. In a stoving or similar machine, the combination with a steam-hammer, a frame, means for securing the frame to the anvil of the steam-hammer, a ram or hammer operating within the frame and means connected to the ram or hammer and adapted to be operated by the steam-hammer for driving forward the ram or hammer.
2. In a stoving or similar machine, the combination of a frame, a ram or hammer operatingwithin the frame, and connecting levers comprising a pressure bar to operate the ram or hammer when the pressure bar is struck.
3. In a stoving or similar machine, the combination with a frame, a ram or hammer disposed approximately horizontally in the frame, a pressure bar, and connecting links and levers for operating the ram or hammer the pressure bar being arranged to receive a blow from a steam-hammer or similar power device.
4. In a stoving or similar machine, the combination with a frame, of a ram or hammer traveling upon rollers in the frame and slightly inclined so as to return to in operative position by gravity, and levers and connections for operating the ram or hammer and adapted to receive and transmit power to the ram or hammer.
5. In a stoving or similar machine, the combination with a frame bearing a series of guides, a ram or hammer traveling upon the guides in the frame, a pair of work supporting arms carried by the frame, and a guide plate on the arms for determining the blow of the ram or hammer.
6. In a stoving or similar machine, the combination of a frame comprising end gage plates adapted to lie between the dies of a steam-hammer and to gage the stroke of the steanrhammer, a pressure bar pivoted in the frame carrying a roller to receive the blow of the steam-hammer, and connected to links and levers for operating the ram or hammer.
7. In a stoving or similar machine, the
of separate plates, of a ram or hammer,
means for guiding the ram or hammer within the frame, a lever pivoted to the frame and to a link connecting with the ram or hammer, an operating pressure bar connected by a link with the lever, and a roller carried by the pressure bar and adapted to be operated by a steam-hammer or similar power device.
In testimony whereof I have hereunto signed my name.
HENRY E, RARIOK.
