MACHINE FOR MAKING FENCE-STAYS.

Specification of LettersPatent.

Patented Aug. 1s, 191s.

Application filed July 31,1916.- Serial No. 112,260.

To all Awhom t may Concern:

Be it known that we, STEPHEN Aims and THOMAS LovnLADY, citizens of the United States, residing at Oklahoma city, in the county of Oklahoma and State of Okla` homa, have invented certain new and useful Improvements in Machines for Making Fence-Stays, of which the following is a specification, reference being had to the accompanying drawings.

An object of the invention is to provide a cheap, simple, and convenient machine for making fence-stays, and more particularly the fence-stay shown in Letters Patent No. 841,17 7, issued to Thomas Mortin Price, on January 15, 1907.

Other objects and advantages of the invention will be set forth in the ensuing de scription.

Figure 1 of the accompanying drawings shows one form of the fence-stay referred to in the above-named patent.

Fig. 2 is a plan view of the improved machine.

Fig. 3 is a reproduction of the right-hand end ofFig. 2, but with the parts shown enlarged and advanced to a little different position.

Fig. 4 is a sectional view taken on the line 4 4 of Fig. 3.

Like characters of reference designate like parts in all the gures.

The fence-stay shown in the above-named patent includes a straight shank 5 and a retaining coil 6 surrounding the shank; said coil and shank being connected together at one end 7, whereby they are held against relative rotative movement.

The improved machine includes a portable base 8, which may be of wood; and this base supports the other parts of the machine.

A round shaft or core 9 has its ends journaled in supporting

bearings

10 and 11 which are mounted permanently on the ends of the base 8, the end pintle 12 of this shaft being provided with a crank 13 for turning it.

A second shaft 14, which is tubular, has one of its ends, 15, j ournaled in the bearing 11, and this shaft is provided with a gearpinion 16 which meshes with a similar gearpinion 17 on the end pintle 18 of the shaft 9.

By this arrangement, the shaft 9, when turned by the crank, 13, causes the tubular shaft 14 to revolve.

lThe opposite end 19 of the shaft 14 is not journaled in the bearing 10, but is journaled i i in a movable block 20 which Valso loosely and slidably embraces the shaft, 9.

The shaft 9 is grooved helically, as at 21,l from end to end, and that portion of the block 2O which embraces said shaft is provided with an inlet 22 to admit the wire 23 used in making the stay; this inlet 22 ex# tending in a direction to allow the wire eX- tending through it to lie down in the groove 21 of said shaft. p

` In using the machine, that portion of the wire 23 which is to form the central straight shank 5 of the stay is inserted in the bore of the shaft 14 at its initial end 19, and the remaining outer portion of said wire, which is to form the retaining coil 6, is bent around at an angle as shown in Fig. 3 and through a slot 24 in a sidewall of said end 19 of the shaft; said remaining portion of the wirethen being swung down into the inlet opening 22 of the block 20 and into the groove 21 `of the shaft 9.l

Now, by turning the crank 13 and revolving the two

shafts

9 and 14 in the directions indicated by the arrows 25 and 26 in Fig. 4, the action of the groove 21 on the wire 23 will cause the latter to force the block 2O along in the direction of the arrow 27 of Fig. 3; the revolving shaft 14 at the same time drawing the wire through said groove and the inlet 22and coiling said wire about itself as shown.

The block 20, in being led along by the wire '23 in the groove 21, relatively supports the two

shafts

9 and 14 just in advance of the point at which the re-action of force is eX- erted in winding the wire.

When the wire 23 is fully wound and the stay completed, the stay maybe withdrawn from the shaft 14, and the block 2O manually returned to initial position. i In order to prevent the block 20 from beingbound on the

shafts

9 and 14 by side draft exerted in winding the wire 23, a rod 28 is mounted parallel with the shafts and supported by the

bearings

10 and 11, and

the blockhas a long integral sleeve 29 `which Y Y slides on said rod.

I-Iaving thus described the invention, we claim:

1. In a fence stay machine, a tubular mem# ber adapted to receive internally one portion of a wire, means to rotate said member to coil eXternally vthe other portion of the wire about said rst portion to produceV a` stay, a

slidably mounted block provided with guide means receiving the outer portion of the Wire and directing it as it is coiled upon the tubular member, and means coperating with the Wire to slide the block.

2. In a machine of the class described, a shaft helically grooved and adapted to be revolved, a second shaft mounted parallel with the first shaft and adapted to Wind Wire, a block slidably and revolubly embracing the twoshafts, the block having an inlet to allow the wire to extend through it and lie in contact with the i'irst-named shaft, the groove of the first-named shaft being adapted to engage the Wire in the inlet of the block and in turn to cause said Wire to move the block along the two shafts.

3. In a fence stay machine, a tubular member adapted to receive internally one portion of a Wire, means to rotate said inember to coil externally the other portion of the Wire about said rst portion to' produce a stay, and a slidably mounted block arranged to move parallel to the tubular member and provided With guide means for directing the Wire in position upon the tubular member, said block being moved longitudinally of the tubular member by the action of the Wire as it is wound thereon.

4. In a fence stay machine7 a tubular member adapted to receive internally one portion of a Wire, means to rotate said tubular member to coil externally the other portion of the Wire about the said first portion thereof to produce a stay, a helically grooved shaft arranged parallel to the tubular member, and a block slidably mounted upon the shaft and formed with a guide opening communicating with the helical groove of the shaft and having an inclination corresponding to the pitch thereof, said guide opening serving to direct the Wire upon the tubular member and the Wire cooperating with the helical groove of the shaft to move the block longitudinally thereon.

5. In a fence stay machine, a base, a tubular member supported above said base and adapted to receive internally one portion of a Wire and coil externally the outer or other portion aboutsaidiirst portion to produce a stay, a carriage provided with means to adjust said outer portion of the Wire in position to be coiled by said tubular member, guide means upon which said carriage is reciprocably mounted, a screw shaft also supported above said base, means operably connecting said shaft and said carriage to cause movement of the latter, and gear mechanism positioned adjacent the end of the base and connected to said tubular member and shaft for rotating the same.

Vitness our' hands this 22 day of July7 1916.
