IBEAD-SHAPING TOOL.

Application filed May 9,

This invention relates to an improvedtinners bead-shaping tool, and seeks, among other objects, to provide a tool especially adapted for opening the flattened end of the bead of an eaves trough or the like and shaping the end of contour.

T he invention seeks, as a further. object, to provide a tool which will eliminate the the bead to its'natural I0 hazard heretofore experienced in opening the end of a flattened eaves trough head so that injury to the operator will be precluded. Still another object is to provide a tool which may be readily forced into the flattened end of a bead and then operated with facility for shaping the bead.

And the inventionseeks, as a. still further object, to provide a tool which will be of simple construction, sturdy and efficient.

Other and incidental objects will appear hereinafter.

In the accompanying drawings:

Figure 1 is a perspective view showing my improved tool in connection with a conven- 5 tional eaves trough.

Figure 2 is a plan view of the tool.

Figure 3 is a. detail sectional view on the line 33 of Figure 2, looking in the direction indicated by the arrows.

In carrying the invention into effect, I employ a pair of crossed levers and 11 pivotally connected by a bolt or other fastening device, while each of said levers is formed with an angularly disposed forward end Portion 12, which end portions lie substantially parallel when the jaws of the levers are closed. Formed on the portion 12 of the jaw 10 is an axially alined cylindrical jaw 13 having a tapered nose 14 which is thus reduced in size and, as best shown in Figures 1 and 2, said nose is formed with flat side faces 15 substantially parallel to the flat side faces of the lever. The nose is thus substantially wedge-shaped, but is, never- 5 theless, provided with rounded upper and lower edges. Formed on the portion 12 of the lever 11 is a semi-cylindrical jaw 16 adapted to overlie the jaw 13 seating fiat thereagainst. The jaw 16 is of a length to extend from the rear end of the jaw 13 to the base of the nose 1 1 of the latter jaw so that the jaw 13 thus projects beyond the forward end of the jaw 16 and, as shown in Figure 1, the portion 12 of the lever 11 is continued along the baokof the jaw 16 to form a reinforcing rib 17therefor.

1925. Serial No. 29,163.

In Figures 1 and- 3 of the drawings, I have shown the manner in which the tool is used. A length of conventional eaves trough is indicated at 18 and the cylindrical bead thereof at 19. In any instance where it becomes necessary to cut off an end of a length of trough, the bead is unavoidably flattened atits adjacent end. Accordingly, before another length of trough can be properly sol dered to the severed end of the former length, it becomes necessary to open and reshape the flattened end of the bead in order that one end of the second length of trough may properly mate with the adjacent end of the first length mentioned. I-Ieretofore, it has been customary to employ a screw driver, cold chisel or the like for opening and reshaping the flattened end of such a bead. However, such tools have not only proven inefficient and unhandy, but injury to the operator has often been caused bythe sudden opening of the bead, withthe result that the hand of the operator, in plunging forward, has been out against the sharp edges of the bead and trough. The present invention has, therefore, been devised with a view of overcoming these disadvantages.

Initially, the lever 10 is grasped and the nose 14 of the jaw 13 inserted into the flattened end of the bead, and, in this connection, it is to be observed that, in cutting a length of trough, the bead is, as shown in Figure 1, always flattened in such manner that the free inner margin of the bead lies substantially parallel to the adjacent side of the trough. In other words, the bead is elongated against the adjacent side of the trough. Accordingly, when inserting the nose 14 in the head, the fiat faces 15 of said nose are presented to the sides of the flattened end of the head. The nose will, therefore, be guided into the bead by said faces while the tool will be located by said faces in such manner that the jaw 16 will be dis posed over the upper side of the bead.

Having initially insertedthe nose 14 of the 13, the lever 10 is pushed forwardly for forcing the jaw into the head and since the lever 11 crosses the lever 10, the latter lever will, should the bead suddenly open to permit the jaw to plunge forwardly, engage the end of the trough for limiting the lever 10 in its forward movement and thus preventing the hand of the operator from being injured against the end of the trough. As the jaw 13 is forced into the bead, as indicated the flattened-end of" the bead will, or": course be" opened by said jaw "sothat the lever 11 may then be grasped for swinging the jaw 16 downwardlyagainst the-bead,

when, by rotating the'jaws"with'respectto the bead and compressing the head -there between, the flattened end' of the bead may,

as; shown in Figure 3,bexiieadily':reshaped to its natural cylindrical contour. As will beperceived, the tool maybe operated with one hand of the opetratorto aceo-n' plishj the entire reshapingoperation of the bead, so

a that should the trough be suspended in place at the eaves of a roof, the other hand ofthe operator 'will be 'free to graspa ladder.' Accidents such as might otherwise 0c cur,"will aeeordingly be avoided.
