T0 ALL WHOM I'I MAY CONOERN:

Be it known that I, WILLIAM SERVISS, of Sidney, in the county of Shelby, and State of Ohio, have invented certain new and useful Improvements in Apparatus for Making Rings; and I do hereby declare'that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, makinga portion of this specification, in which- Figure 1 is a side View of an apparatus constructed according to my invention.

Figure 2 is an end view and partial section of the same.

Figure 3 is a plan View of the same. I

Figures 4 and 5 are detached views of rings made by means of the apparatus.

Similar letters of reference indicate corresponding parts in the several gures.

l'Ihis invention is designed more especially for making the rings commonly employed for-the handles of tin, sheet-iron, and copper-ware, and it consists in mandi-els made interchangeable, and constructed with a hole near one end, in combination with a supporting-shaft furnished with a crank, whereby the wire mayl be readily bent into the required form, and whereby the apparatus is adapted formaking rings of different shapes and sizes.

The invention further consists in the arrangement of the mandrel and shaft with reference to a. grooved anvil, in such manner that the curved pai-tions of the ring may, when required, be readily brought into finished shape with the hammer. V l p The invention further consists in a novel arrangement of flat-faced supplemental anvils, with reference to the anvil and the mandrelA hercinbefore mentioned, whereby the straight portions of the class of rings referred to may be conveniently worked into .proper form and positio To enable others to understand the nature and construction of my invention, I will proceed to 'describe it with reference to the drawings. u

A represents a solid standard, upon the upper end of which is formed the anvil B, the face or'upper surface of which is made concave in its cross-section, as shown more fully in iig. 2, and Aformed with transverse semicircular grooves, d, the purpose of which willbe presently set forth. Projecting horizontally from one side of this anvil B are two fiat-faced anvils, A* Bi, one of which is larger than the other; and projecting in Alike manner from the -opposite side of the main anvil B,.is 'another lat-faced anvil, 0*, of a'still larger size than those marked A* B*, 'nstmentioned The oiice of these su lemental anvils A B* C* is to enable the strairrht .l PP c portions ofrings designed for handles for sheet-metal ware to be brought into the required shape und position, as hereinafter further explained. .Working through the standard A, just below the anvil B thereon, is a horizontal shaft, C, one end of which is provided with a c rank, b, andthe opposite end portion of which is made lat on one side, as shown at c, in iig. 2i Fitted nponthis portion of thel shaft C, so as to turn therewith, is a mandrel, I), which maybe retained thereon by a nut, a', and which, taken transversely, corresponds in shape and size with the interior of the ring designed to be formed upon it, and is provided at one end with a hole, Inasmuch as the mandrel may be readily detached from the shaft, interchangeable mandrels o f different sizes may be employed upon the same apparatus for making different kinds` of rings.

In using the apparatus, the end of the wire from which the rings are made is inserted in the hole b of the mandrel, which is then rotated by means of the crank b, and the Wire is coiled thereon, which being done, the

coils of the wire are divided transversely at or near the centre of the flat portion c of the mandrel, when the rings are made straight' or flattened at one side, as shown in figs. 4 vand 5, and are then removed fronrthe man! drel, each coil being separately brought into the form required in thefinished ring by properly shaping its curved portions in the semicircular grooves a by means of a suitable hammer, and bringing the two ends ol' its flat portionin line and in contact with each other by hammering upon the tlat faces of one of the supplemental anvils A* B* What I claim as my invention, and desire to secure by Letters Patent, is-

1. The interchangeable.mandi-els formed ,wtlra hole near one'end, in combination with the shaft furnished with a crank, substantially as and for the purpose specified. t

2. The arrangement of the mandrel upon the shaft C', with reference to the anvil B, furnished with lffrooves a in its upper surface, substantially as and for the purpose specified.

3. The supplemental latsfaced anvils A (1*, arranged in relation with the main anvil B and the mandrel on the shaft G, substantially as and for the purpose specified.
