METHOD OF BREAKING RQDS 0R BARS.
Application filed September 16, 1918.
' To (all whom it may concern:
Be it known that We, (1) THOMAS l). DALLMEYER, (2) GoUvnnNnUn G. BROWN, and (3) JAMES R. SCHULTZ, citizens of the United States, and residents of (1) Pittsburgh and (2 and 3) Oakmont, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Methods of Breaking Rods or Bars; and we dohereby declare the following to be a full, clear, and exact description thereof.
Our invention relates to method of breaking rods or bars, and more especially for use in breaking of round or square bars for shell-slugs.
The object our our invention is to pro vide a simple and eflicient method of breaking off metal bars in desired lengths, and thereby create a saving in time as well as power required for the breaking of such bars.
Our invention consists, generally stated, in nicking the rod or bar and by the same stroke breaking oil a section previously nicked, thereby completing by one stroke what has heretofore required at least two strokes, one for nicking and the other for breaking.
In the accompanying drawings, F1gure 1 is a sectional View of apparatus for carrying out our method showing the commencement of the process and the rod in position for nicking; Fig. 2 shows the nieking of the rod; Fig. 3 shows the rod nicked and adyanced for the second nieking stroke; and Fig. 4 shows the nieking and breaking stroke.
In the drawing, the numeral 2 designates a suitable base-block upon which is supported the breakerbase 3. This br aker-base 3 has the seats 4t, 5 and 6 formed therein. In the seat 4: is keyed the support 7 g in the seat 5 is keyed the lower nicking tool or chisel 8, and in the seat 6 is keyed the breakerblock 9.
In the rear of the breaker-base is the gage 10, which is adapted to yield slightly under pressure, due to the action of the spring 11.
The upper movable die-block 12 is connected to a suitable press or other reciproeating device, and keyed to said die-block is the upper nicking tool. or chisel 13. The
Specification of Letters Patent.
Patented July 8, 1919.
Serial No. 254,197.
die-block 12 also carries the breaker 11 which, due to the action of the spring 15, is capable of yielding sli htly, so as to relieve the strain.
The metal rod 16 to be broken up into lengths for shell-slugs is advanced into position until its forward end comes into contact with the temporary gage 17, as indicated in Fig. l. The upper die is then lowered, and through the pressure, nicks are made by the nicking tools at opposite sides 01 the bar, as shown in Fig. 2. The forward end of the bar rests on the block 9, and by the action of the nickinp; tools, said forward end of the bar beyond the nieking point is slightly inclined upwardly. After this first nicking operation, the rod is advanced until the forward end of the rod bears against the gage 10 with the nicked portion resting on the block 9. The upper die is again lowered and the nieking tools et as before to nick the bar while at the same time the breaker 1% coming in contact with the section of the bar previously nicked, forces said section downwardly and breaks the bar On the line of the nicks, as clearly indicated in Fig. 4. The 10 yields slightly as the inclined end of the bar is forced domiwardly, so as to permit the bar to pass the gage without jamming, and the broken piece falls down to a point below.
In this way, after the bar has been once nicked, the succeeding nicking' operations also result in a breaking eff of the previously nicked portions so that by the same stroke, the nicking and breaking is acco1nplished, thereby greatly reducing the time as well as the power required.
What we claim is:
1. The method of breaking metal rods or bars consisting in nicking the rod or bar and by the same nicking stroke breaking 0d a section previously nicked.
2. The method of breaking metal rods or bars consisting in ni-eking the rod or bar at opposite points, and by the same nicking stroke breaking 0H a section previously nicked.
3. The method of breaking metal rods or bars consisting in nieking the rod or bar and bending the metal upwardly beyond the picking point, and by the same picking stroke breaking 0E a section previously BROWN, and JAMEs R. SCHULT have hereniekecl. unto set our hands.
4. The method of breakin metal rods 01' bars consistin in supportii the rods at THOMAS DONNELLY DALLMEYER' D GOUVERNEUR G. BROWN. 5 the polnt of nlck 1ng and at a polnt on the JAMES R SCHULTZ rod prevlously nloked, applying a meklng stroke, and by the same stroke breaking the Witnesses: metal at the point previously nicked. HAROLD J. VENGLE,
In testimony whereof We, the said GERALDINE L. JOHNSTON, 10 THOMAS D. DALLMIEYER, GOUVERNEUR G. FRANCIS M. HUGHEs.
