To aZZ whom it may concern:

Be it known that I, PARKER SHACKLETON, a citizen of the United States, residing at Cleve land, Cuyahoga county, Ohio, have invented certain new and useful Improvements in Gutter-Beading Devices, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The object of this invention is to furnish a simple construction, whereby the bending of gutter-beads may be effected either by an independent apparatus or by a cheap attachment to an ordinary cornice-brake and without the use of a groove in the forming-rod.

My device may be applied to an independent machine or as a removable attachment for any cornice-brake in which the upper or movable clamping-leaf is adjustable to and from the edge of the lower stationary leaf. The beading-machine shown herein may also be converted into a specicsof cornice-brake at pleasure by removing the rabbeted fixture and substituting a beveled flange or a former of any desired shape upon the front edge of the upper leaf.

My improvements will be understood by reference to the annexed drawings, in which Figures 1 to S, inclusive, represent transverse sections of two or three of the required leaves.

As the means for mounting and operating the three principal members in a cornicebrake-namely, the fixed clampinglcaf A, the movable clamping-leaf B, and the turningleaf C-are already well known, I have not shown the frame or actuating mechanism of the members in the annexed drawings, but have simply shown the three members in their proper relations at different stages of the bending operations described herein.

Fig. 1 represents the upper and lower elam'ping-leaves,with a rod clamped near the front edge of a sheet of metal and the turning-leaf in its normal position. Fig. 2 represents the same parts, with the turning leaf raised and the initial bend produced upon the edge of the sheet metal. Fig. 3 repre sents the sheet of metal reversed, with its curved edge inserted beneath and behind the forming-rod and the turning-leaf in its normal position, while Fig. represents the same parts with the turning-leaf elevated and the (No model.)

bend continued by forcing the sheet of metal upward against the exposed front of the rod. Fig. 5 representsthe leaves A and B and the rabbeted holder D, with afillerinscrted there in to hold a rod smaller than that shown in Figs. 1 to 4. Fig. 6 represents the same parts, with a still smaller filler and red, the rods in both figures being clamped upon the sheet metal to form the initial bend. Fig. 7 represents the leavcsAand B,with abeveled flange substituted for the rabbeted holder. Fig. 8 represents the leaves A and B of an ordinary cornice-b1'akc,\vitl1therabbetedholdersecured thereon as a separate attachment, the corner of the rabbeted holder being rounded to fit the rod. Fig. 9 is a plan of the leaf B,with the rabbeted holder and a filler attached by bolts and screws; and Fig. 10 is a front elevation of the same leaf, with the holder and filler attached by dovetails, a portion of the holder and filler being broken away to show the reeess J in the leaf B. Fig. 11 shows the metal when beaded; Fig. 12, the completed gutter, and Fig. 13 shows another form of gutter completed.

I am aware that heretofore a forming-rod has been clamped between jaws of various shapes, and that the sheet metal has been bent around the same either by rotating a grooved rod between the jaws or by bending the sheet metal around a rigidly-clamped rod, and my invention differs from the constructions heretofore employed chiefly in the extreme simplicity of the device whichis used for holding and clamping the forming-rod, and which consists merely in a longitudinal rabbet provided in the front edge of the clamping-leaf and opening toward the turning-leaf, so that the latter may operate to bend the sheet metal around the exposed side of the rod. Such rabbet may be formed directly in the front corner of the clamping-leaf; but I prefer to form it in the front corner of a separate holder, D, (shown in Figs. 2 to 6,) having a flange, D for attachment to the clamping-leaf, the latter method admitting of more convenient repair and the substitution of rabbeted holders of different sizes, or the application successively of different formers to the clamping-leaf, as at J in Fig. 7, for making various-shaped bonds. The rabbet is made of lesser height than the diameter of the forming-rod F so IOC that when the clamping-leaf B is pressed toward the leaf A the rod is clamped upon the latter close to its forward edge. The front side of the rod is then wholly exposed, so that the sheet metal may be wrapped around the same by the elevation of the turning-leaf, as shown in Figs. 2 and 4.

To form a bead with this mechanism, the sheet of metalG is inserted between the clamping-jaws, with its edge projecting beneath the rod E and extending sufficiently over the operative edge of the turning-leaf to be raised and pressed against the rod by the latter, as shown in Fig. 2. The sheet metal is then removed from the clamping-leaves and reversed, with its previously-bent edge inserted beneath the rod, as shown in Fig. 3. It isthen clamped between the rod and the leaf A, and the elevation of the turning-leaf serves, as shown in Fig. 4, to form a continuation of the bend. This last operation may be repeated as often as is necessary to complete the bead, the leaf 0 being lowered, the sheet metalturned downward again to the horizontal position exhibited in Fig. 3, and the leaf again raised to bend the sheet metal after the rod has been clamped thereon. As the rabbet is entirely open upon the side adjacent to the turningleaf where the sheet metal is chiefly handled during the operation of forming the head, it is obvious that the latter may be readily removed from the rabbet at the close of the forming operation and the rod removed therefrom for subsequent use.

By the application of a filler or angle-strip of suitable thickness to the rabbet a smaller rod may be inserted therein and the bead formed in exactly the same manner, and the same apparatus may therefore be used to form beads of any desired size with equal facility, and the operation of turning a bead upon the smallest rod may be effected with greater ease than upon the grooved rods heretofore used by rotating them between clamping-jaws, and which necessarily require considerable size and strength to admit a groove and to endure the torsional strain required to form a bead along the edge of a long strip of sheet metal.

The separate holders, in which the rabbet is formed for attachment to the clampingjaw, are readily attached thereto by means of bolts I or other suitable fastenings, and the fillers F may be fastened therein by screws 1, as shown in Fig. 5, or by dovetails Z, formed or secured thereon and fitted to grooves m in the top of the rabbet, as in Fig. 10. 'When screws or bolts are used, the holes for the same may be slotted out to the edge of the metal, as shown at h h in the plan of the leaf B and holder D in Fig. 9, while the application of the dovetails Z to both the filler F and the flange D is shown in Fig. 10.

In Fig. 7 is shown the method of operating my beading-machine as a cornice-brake by the removal of the rabbeted holder D and the insertion of a beveled flange or corner-plate, J, the plate being secured by bolts I, inserted in the slots h, in a manner similar to the bolts I. The sharp front corner of such plate adapts it to form acute angles, and the substitution of formers with a round front corner in place of the plate J, or the application of such formers to the outer inclined face of the leaf B, as in other cornice-bending machines, adapts my apparatus to perform very much of the same work that is effected in ordinary cornice-brakes.

In the construction shown in Figs. 1 to 7, inclusive, the upper leaf is recessed at J upon its under side to receive the flange D or J, and the solid front corner of such leaf is not, therefore, when the holder D is removed from the front corner of the leaf A, directly adapted for clamping sheets of metal to make acute bends; but my device may be applied as an attachment tosuch machines as are provided with a sharp corner at the front edge of the upper leaf by raising such leaf sufficiently to insert the flange D beneath the same and retracting such leaf sufficiently to bring the rabbet D over the front corner ofv the lower leaf. The means for retracting such upper clampingleaf have already been used in many cornicebrakes, and are not therefore shown herein. The leaf B is shown in Fig. 8 with my rabbeted holder attached thereto, so as to operate in conjunction with the upper leaves in the desired manner, the upper leaf being raised sufficiently, when thususcd, to admit of the flange D and the holder D being preferably formed to embrace the sharp corner of the leaf'B to support the holder more per fectly upon its rear side.

I have represented the rabbet in Fig. 8 as having a rounded corner in contact with the rod E, which form may be used instead of that constructed with its sides meeting to form an angle; but it is obvious that the precise form of the inner surface of the rabbet is immaterial.

I am aware that a loose rod has been held 7 in an adjustable jaw to bend sheet metal, and do not therefore claim such a construction, broadly; but,

Having set forth the features essential to my own construction, what I claim herein is' 1. In a gutter-beading device, the combination, with the stationary leaf A and the movable clamping-leaf B, of the rabbeted holder D, applied to the front edge of the clampingleaf B, a round rod fitted in the rabbet of such holder, and a turning-leaf, 0, operating to bend the sheet metal against the rod, as and for the purpose set forth.
