MATHEW A. HEINEN, OF WATERLOO, IOWA.
BAR-BENDING MACHINE.
To all whom it may concern:
Be it known that I, MATHEW A. HEINEN, a citizen of the United States of America, and a resident of WVaterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements'in Bar-Bending Machines, of which the following is a specification.
My invention relates to improvements in bar-bending machines, and the object of my .improvement is to provide such a machine with means for bending a bar to any desired angle. This object I have accomplished by means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which:
Figure 1 is an upper plan view of my bar bending machine with its moving parts in their positions at the completion of the act of bending a bar to a desired angle. Fig. 2 is a sectional view of said device taken on the broken line ab of said Fig. 1.
Similar numerals of reference denote corresponding parts throughout the several views.
The frame or base of said machine is a flat substantially oblong plate 1 having a plurality of bolt holes adapted to receive securing-bolts 3 used to fixedly mount said base upon a supporting body 2 by means of nuts 4. The outer half of said base 1 is of nearly circular form andprojects beyond the supporting body-2. Said base has an upwardly directed integral cylindrical solid abutment 7, and longitudinally spaced parallel transverse ribs 5 and 6. The outer circular part of said base 1 is centrally orificed at 14 to receive a pivot bolt 11. The enlarged head 10 of said bolt is of cylindrical shape. The numeral 8 denotes a concentric slot in the plate 1 which extends through the larger part of a circle about said pivot bolt 11. The numeral 9 denotes a plurality of relatively small sockets or pin-holes adapted to receive interchangeably a shortheaded pin 27. said holes being arranged circularly in said base 1 and concentrically about the pivot bolt 11 and the curved slot 8. The numeral 13 denotes a U-shaped body whose forks are of equal length and are orificed transversely in line at 20 to permit them to be pivoted on the pivot bolt 11 over and under the upper and lower surfaces of said base 1, the nut 12 being used to secure said body to the pivot bolt 11.
Specification of Letters Patent.
Patented Mar. '7, 1916.
Application filed April 19, 1915. Serial No. 22,383.
The numeral 15 denotes a pin passed through the alined transverse openings 18 in the U-shaped body 13 and through the arcshaped slot 8 in the intermediate base-plate 1 and secured by means of a nut 17. An anti-friction roller 16 is rotatably mounted on the upwardly projecting end of said pin 15.
The cross-connection of the U-shaped body 13 has a rectangular orifice 24 to receive one end of a hand-lever 25 therethrough. The forks of said body, together with the intermediate part of the lever, have registering orifices 21 and 23 adapted to .receive a removable securing pin 22.
When it is desired to angularly bend a bar 26, the pin 27 is placed in one of the pinsookets 9. The bar is laid horizontally across the transverse ribs 5 and 6 to pass between the abutment 7 and the pivot-head 10 and between said head 10 and the upwardly projecting part or anti-friction roller on the pin 15. The lever 25 is then swung in the direction of the arrow, causing the pin 15 and its roller 16 to engage said bar and bend it angularly to one side until the U-shaped body 13 comes in contact with the pin 27, thus forming the desired angle in the bar. It is obvious that other desired angles may be formed in the bar by re-locating the pin 27 in any other of the sockets 9. The part of the pin 15 which extends into the arcshaped slot 8, rides upon the inner wall of the slot, guides and reinforces the lever action.
The lever 25 may be detached from said U-shaped body, by removing the pin 22.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:
A bar-bending machine, comprising a fixed support, a base-plate secured on said support toproject therefrom, the projecting part having a circular orifice, a pivot-bolt secured in said orifice, and having a cylindrical head, said plate having an arc-shaped slot concentric with said pivot-bolt and having an integral abutment near one end of said slot, a U-shaped body whose members are located'on opposite sides of said plate, orificed in line, and pivotally mounted on said pivot bolt, the integral boss-connection of said members being orificed, a lever passedv through the said orifice, said members and lever having registering orifices, a
headed pin seated in said orifices, said members being orificed in line with said arcshaped sl t,a-he'aded bolt passed through said orifices and slot, said, plate having an arcshaped row of small orifices concentric With said pivot-bolt, a headed pin adapted to be removably inserted in any of said small orifices in the path of movement of the 11pper of said members, and said plate having raised ribs adapted to support a bar while 10 being bent.
Signed at \Vaterloo, Iowa, this 5th day of April, 1915.
