T0 ALL WHOM Il MAY CONCERN: l

)e it known that I, P. L. SLAYTON, of the city, county, and State of New York, have invented anew and improved Machine for Tempel-ing Wire; and I do hereby declare that Athe following is a. full`clear, and exact description thereof, which will enable others skilled in the urt to make and use the same, reference being had to the accompanying drawings, forming part of this specification. l

This invention relates to a new and improved machine for teml'iering wire, and is.niore especially' designed for tempering wire braces for umbrellas and parasols. and straightening the saine during the 'process of tempering. In the accompanying sheet of drawings- Figure 1 is a side view of my invention.

Similar letters of reference indicate like parts A A represent two standards, in the upper parts of which there are fitted cylindrical heads, B B', having each aeentral hole, rf, through it. In the inner sides of these heads there are circular recesses or chambers to receive the ends oi' four hars U, each of which is u longitudinal quarter of a cylinder, as shown in fig. 4. The ends ot' the bars C are secured in the recesses or chambers in the heads B B by means of screws D. The hars C arenot in close contact. Spaces are allowed between them te receive stripsor bars, E, of metal, the inner ends of which arey ol V-form, :is shown clearly in fig. 4. These strips or bars a1e`adjustable,that is to say, may he raised higher or lower in the spaces between thc'bars C by means of .screws F F', the screws F being secured in thc strips or hars E, passing through the sides of B B', and having nuts on their outer ends, the screws F passing through curved :natal hars (i, which are attached to the exterior of the bars C by screws D',

and I'bear upon the outer edges of the strips or hars iii. By this means the strips or bars E may be adjusted,

further inward or outward and secured at any desireihpoint, so that a greater or less space may be allowed between their inn'er ends, as desired` '.lhc strips or bars E have each a. hole, c, extending longitudinally through them, and these holes c coininunicate, hy means of small perforations, fl, with longitudinal recesses e in the bars G, the recesses e extending the whole length of C and nearly to the inner ends of thelsanie, and having holes,

f, at their bottoms or inner ends, the holesfheingrnuch larger in diameter than the perforations d, but in line with the samef. Besides these large holes f, the recesses c have small pel-felations,- g, made through their inner ends, which are in line with the'spaces between the strips or hars E, as shown in figs. 1, 2, and The head B has a groove oi .rceess, h, made in its periphery and extending entirely around it. This groove o1' recess is enclosed hy the standard A, in which the head B is fit-tod, and communicates by psages with the holes c in thi` strips or bars E, as shown clearly in fig. 2. H is a pipe, which coininunieates with the recess 7i, and through which gas is conducted into t, and from thence into the holes c in the strips or harsE, the gas passing from c into the perfora'itions'cl, at th'.` outer oriiiees ot' which it is burned, as shown clearly in iig. A4, the inner portions of the jets being within the recesses e of the hars C, as shown in iig. 4. The perfect combustion of the gas is insured by the admission oi' air' te the same through tho holes y, the air passing into the latter from the spaces between the inner ends of the strips or bars E. The gas-jets heat the bars C und the strips orbars E, and, if necessary or desired, the device may be enclosed within ajacket in order-to prevent the radiation of heat. The wires ax, shown in red, are previously tempered as hard as possible in the usual way, and are then reduced or brought down to u spring` or blue temper by inserting them, one at a time, in the opening between the inner ends of the strips or hars E, the wires being straightimed in passingv between theinncr edges of the bars or strips. The .trips or bars' E are adjusted further` in or ont so as to regulate the size oi the opening between their inner edges to suit the thickness of' the wire to he tempered. Several of these devices are to be used by one operation at the .saine time in order that no time may he lost, as cach wire requires to be left in a device suiliciently long to have the temper reduced to the` proper degree. One operator would require about five or' six ot' the devices in order inat he may be kept constantly at work.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent- The radially adjustable strips or bars E, arranged between`-tlw guide-bars C, and provided with holes or gas passages c, communicating with recesses e in the guido-bars C', all arranged substantially in the manner us and for the purpose set forth. I

I also claim the central passage formed by the strips-or b rs E of such a. size as to recois-'e the Wire tovhe tempered, and to permit a current of air to pass to the gas-jets, and this I claim whether said strips E are adjustable or stationary.
