The object of the invention is to secure heads on rods as for instance'tlie heads to a vise handle or cutting tool. Illn' devices ofthe character described, these heads aresubjected to rather severe use and on theother hand, they are so used by the;operator that venienthandling. Furthermore, in forming such rods as for vise handles it'is'"desirable to place at least-one-head on the rod after the rod is in placeiinithe vi'se screw head.

The means for carrying-out the piiocessare, illustrated in the accompanying drawings as follows Figure 1 shows a section on the line 11 in Figs. 5 and 6. Fig. 2 shows a section on the line 22 in Figs. 5and 6. Fig. 3 shows a head in the process of forming, the rod and head being a section on the line 3-3 in Fig. 4;. Fig. 4 shows a section on the 'line 44 in Fig. 3. Fig. 5 shows a section similar to the section shown in Fig. 3 on the line 5-5 in Fig. 2 with the head in a later stage of construction.

1n it of a size sufiicient to permit the entry of the rod 1. The cross dimension of the opening between the sides 5 is approximately the diameter of the rod 1. The 'openlng as will be observed is ovalf Theato ribs 6 extend across the ends of the oval opening so that when the rod is in place in the opening, these ribs 6 will register with the grooves 2. The ribs are of a depth corresponding to the depth of the grooves and also correspond approximated-y in size to the grooves, the size of the ribsbeing such as to make a tight fit in the grooves. The cross dimension of the opening between the ends 7 of the opening is greaterr ao than the diameter of the rod 1 in order to permit of the depth of the ribs 6 approximating the depth of the groove 2. It will be understood that the ribs 6' are a sufficient distance apart to permit the entry 1 1 5 of therod 1 between the ribs as shown in Fig. 3. The rod is placed in the opening as shown in Fig. 3 and the head placed in a die 8, a similar die '9'being carried onythe plunger 10 of the hammer. The hammer is of sufiicient force to press the head 3 into spherical shape,.the original shape of the head being just. sufficiently oval so that when the rib 6 is forced into the groove 2 and the end 7 into contact with the rod, the head as a whole assumes spherical shape, the malleable metal having sufficient ductility to take on the new shape and form a continuous contact with the rod. To accomplish this continuous contact and consequent better union, it is desirable to form the opening 4 of such shape to provide just sufiicient metal to accomplish this purpose when the head has been brought to its final or desired shape. This forms a perfeet head with a continuous and unobstructed outer surface and at the same time the union between the head and the-rod is secure for all purposes. The hammering nec-, essary to shift the shape burnishes the head to a certain extent-and this is also desirable. T have described the process as applied to sphericalheads but it is adapted to other heads as shown in Figs. 7, 8 and 9 wherein an elongated handle of an ordinary cutting tool is shown and in Figs. 10 and 11 wherein a vise screw head is shown.

The structure shown in Figs. 7, 8 and 9 comprises the head 11, the handle being hollow to save weight. In this structure them is a socket 12 in the outer Wall into which the end of the rod 1 extends, the sides of the end of the rod being flattened at the same time as the slotting is done. In this way the endof the rod assists in preventing the turning of the handle on the rod. The rod is also provided with the slot 2 corresponding to theslot 2 and the ribs 6 come flush with the surface of the handle. In other ways the process as heretofore described is used in assembling the handle on the rod.

In Figs. 10 and 11 a vise screw head is shown, the head having the transverse opening 13 to receive a vise handle similar to the handle shown in Fig. 5. The rod 1 has the slot 2 similar to the slot 2 and the head has the opening 14; similar to the opening f and the rib 15 similar to the rib 6. The process of assembling is similar to that heretofore described, that is, the rod 1" is slotted and the head is cast with an opening out of round and of sufficient size to receive the rod. After the rod is in place, the shank of the head is compressed carrying the rib 15 into the slot 2" closing the shank around the rod.

What I claim as new is 1. The method of forming headed rods which consists in taking arod provided with a reduced part near one end, taking a malleable head provided with an opening of a size to receive the rod end, there being a variation in the wall of the head increasmg the thickness of the same, placing the rod end in the opening with the reduced portion opposite the part of the wall having the variation of increased thickness, and compressing and shaping the outer surface of the head by pressure exerted simultaneously over the greater part of the surface of the head and forcing the walls of the head about the rod, the metal of the wall having the variation of increased thickness being forced into the reduced portion of the rod and thus securing the head in intimate and fixed relation with the rod.

2. The method of forming headed rods which consists in taking a rod and slotting the same forming a reduced part near one end, taking a malleable head with a greater than normal dimension in one direction and an oblong opening of a size to receive the rod end there being an inwardly projecting rib in the head corresponding to the slot in the rod, placing the rod end in the opening,

compressing and shaping the head to normal form, and compressing the walls thereof about the rod thus forcing the inwardly projecting rib into the slot so as to secure the head in intimate and fixed relation with the rod.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
