MACHINE FOR FOLDING SHEET METAL.
SPECIFICATION forming part. of Letters Patent No. 314,311, dated March 24, 1885.
Application file.l December I8, 1834. (No mode.)
To all whom it may concern:
Be it known that 1, WILLIAM J. BAYRER, a citizen of the United States, residing at Southington, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Machines for Folding Sheet Metal,-of which the following is a specification.
My invention is an improvement upon the folder patented to O. W. Stow, February 28, 1860, No. 27,319; and the objects of my improvement are to facilitate the manufacture of the machine, to enable one part thereof when worn to be duplicated at a small expense, and
to positively lock the gage in position when desired.
In the accompanying drawings, Figure 1 is a plan View of my sheet-metal-folding machine. Fig. 2 is afront elevation. Fig. 3 is a side elevation. Fig. 4is apartial section thereof on line 00 x of Fig. 1. Fig. 5 is another partial section thereofon liney yof Fig. 1, and Fig. 6 is a front elevation of a portion of the slide which moves the gage.
The main portion of the machine need not be described in detail, because it is substantially the same as has heretofore been manufactured under the said patent to Stow.
A designates the folding-bar, which turns in the bearings 11, which bearings are mounted upon the swinging frame b bl This bar is moved by means of the lever B.
C designates the plate, around the edge of which the folding-bar turns, and D designates the gage underneath the plate C, for regulating the width of the lock to be turned. In the prior machines this gage was moved by the direct action of a screw located in the frame at about the middle of its length. I provide this gage D with two wings having oblique slots d. In Fig. 1 a part of the plate C is broken away and removed, so as to better show the other parts. One end of this gage is shown in full lines in this figure, while the contour of its opposite end is indicated by broken lines.
Underneath the gage D, and lying in a longitudinal groove through the fr'ameE, is the gage-slide f, Figs. 1, 4., and 6, which slide is provided with projections 0r lugs g, which are received by the oblique slots at in the gage.
The end of this gage-slide f is bored and threaded to receive a left-hand screw, and in the frame is a nut, h, which is threaded to receive a right-hand screw.
F designates thegage-adj usting screw, which screw is provided with a right and left hand portion, to fit the nut h and end of slidef, respectively, as shown most clearly in Fig. -1. The slidefhaving lugs which engage the oblique slots in the gage D, the screw F and its nut 72 constitute the gage-adj usting mechanism in its improved form. In said Fig. lthe gage is represented as thrown forward to its extreme limit. By turning the gage-screw F in a left-handed direction the gage-slide f will be moved' to the right, and thereby draw the gage D back away fromthe edge of the plate.
The gage-slide lies within alongitudinal groove within the frame, which is milled out so that the slide may be neatly fitted thereto. For the purpose of saving labor in fitting the slide, portions of its sides are cut away, as shown in Fig. 1, care being taken, however, to leave a bearing-surface of some length, which will bear closely against the wall of the groove near the middle of the length of the frame, and upon that side which is nearest the folding-bar.
When a large job of work of a particular style is to be done, it sometimes happens, especially when the machine is much worn, that the position of the gage may change a little from the position to which it was left by the gage-adjusting screw. In order to prevent such an accident I provide the machine with means, in addition to the gageradjusting screw, for locking the gage-slide against movement in either direction. This means, in the present instance, consists in a simple setscrew, k, in such a position as to press upon the gage-slide near the middle of its length and bind it firmly against the opposite wall of the groove in which it slides whenever it is desired to hold it in position with greater positiveness than it would be held by the gage-adjusting screw alone. The setscrew of course must be loosened or turned back preparatory to adjusting the gage to a different position.
The nut 71. for the adjusting-screw is a part which is subject to great wear. In order that this nut when worn may be duplicated or re newed without removing the entire frame of gage to move back and forth upon a longitudithe n1acl1iue,I have made this nut so that it is readily attachable and detachable. By so do ing I am also enabled, when the nut is removed, to leave the groove for the gage-slide f open from end to end of the frame E, where by a milling-tool may be run through the groove, so that it can be milled much more conveniently and at less expense than could be the case provided the nut were an integral part of the frame. I secure this nut, which is formed separately from the frame E, in place by means of the tcnon m, Fig. 5, which fits into a hole in the frame underneath the body of the nut, while the plate 0, which is held upon the frame by screws in the ordinary man ner, bears upon the top of the nut in such manner as to prevent it from working up out of place. By removing this plate the nut can be readily taken out and a new one substituted therefor at a trivial cost.
I have shown and described the oblique slots in the gage and the studs on the gageslide as means for operatively connecting said parts. Other means which will cause the nal movement of the gage-slide I consider the equivalent of said slots and studs.
I claim as my invention 1. In a machine for folding sheet metal, the combination of the gage D, the gage-adjusting mechanism for moving said gage, and means, in addition to the adjusting mechanism, for locking said gage against movement in either direction, substantially as described, and for the purpose specified.
2. In a machine for folding sheet metal,t-he combination of the frame, the gage D, mounted thereon, and having the oblique slots, the gageslidef, having the studs which enter said ohlique slots and move longitudinally within a groove in the frame, the gage-adjusting screw F, and the nut 72, formed separately from the frame E, substantially asdcscribed, and for the purpose specified.
