To /f// lli/mm if ntrny/ concer/L:

Be it known that I, ARonni'rr O. (inassoo, a citizen ot' the United States, residingl in Hammond, in the county ot' Lake and State of Indiana, have invented a new and useful Improvement in Machines Vfor Attaching' Stays to Iience-IVI'es. of which the following' is a specilication.

This invention relates to improvements in tools t'or attaching wire stays to tence-wires, and is designed to be. used in the putt-ingl together the tence shown in the Patent No.

615,260, granted to Frederick A. Curtis Def l cember t3, 1898.

The invention consists 1n the novel combinations ot' parts and devices and in the novel 1 construction ot' parts and devices herein shown or described.

The objectol' the invention has been to devise a i'nachine which will attach the stays lirmly, quickly and asily and which can be held in the hand and used as a hand-tool.

In the accompanying drawings, Vforming a part ot' this specitication, Figure 1 is a plan ot' the invention, showing it positioned ready to operate. Fig. 2 is a partial plan of the invention at the conclusion of the operation.

Fig. ZE is a longitudinal vertical section on the line il 2% ot' Fig. "2. Fig. I is a transverse section showing the stationary jaw in elevation. Fig. I is a detail ot' one ot' the bending Jaws. Fig. l 1s a plan showing a modified construe* tion. Fig. T is a section ot' the tence, and Fig. tl a section on the line S t ot' Fig. T. Fig.

I'eterring to the drawings, Il) Il) represent the Vtence strands or wires, and 11 one ot' the i The latter previous to its being upon the Vtence-wires has its ends l tence-staysplaced doubled over so that the points stand parallel with the body portion, forming' hooks by which it may be loosely caught on adjacent 'fencestrands preparatory to being' secured thereon by the machine or tool otl my present bolts 19.

i the bent portions ot' the stay.

I invention. This will be understood trom Fig.

9. The machine is intended to bend the points l 13 ot the stays so that they will completely l encircle the fence-wire, or, in other words, the

f machine closes the open hooks ot' the stays 50 upon the fence-wire, thereby making the attaclnnent both secure and permanent. The machilie also t'orms a bend Il in the tencewire, adapted to prevent the stay from slipping thereon, and it also t'orms the shoulder 55 l or bend 15 in the stay adjacent to the wire.

l The machine embodies a stationary forming-jaw, a movable t'Orming'-jaw,a trame-plate, and means for actuating the movable jaw. The trame-plate (shown at 16) has a flange I7 60 at its end, acting` as an abutmentagainst which thestationaryjaw leis positioned. Thisjaw is in the form of a bridge arranged transversely l ot' the trame, to which its ends 5l) are bolted by It has a notch 20 on theactingside ot' 65 its central or raised portion intended to give room to the body portion ot' the stay, as seen at Figs. L) and 3, and its undersurface back ot' the notch is recessed, as at QI, to give room to At each side ot' 70 the notch its t'aces 5I are adapted to act as abutments to the tence-wire to resist the pressure by the movable jaw when it t'ornis the bend l1. The movable jaw is formed on the end ol a slide Q2 and is provided with an acting tace 75 consisting' ol a rounded, inclined, and lorwardly-projecting portion '23, adapted to enter under the stationary liaw, and a breast or vertical portion 'Z-t. a groove '25 heilig' formed in the parts 23 and 'Z-L, as seen plainly at Fig. SO

5, adapted to serve as a seat for the stay during the operation of the machine. This groove is preferably curved or tm'ned to one side, so it will assist the pointotl the stay in assuming' a position in which it may lap by the main 85 portion of the stay. The movable jaw is also i provided with a projecting lip "26, adapted to i press against the body ot' the stay a short dis l tance above the coiled portion. The slide rel ceives motion in closing the stay upon the 9 fence-wire from a pair of levers 27 27, pivl oted at 28 28 and havingarms 29 29 engaging l shoulders 3() 30, formed on the rear end of l the slide. A retracting-spring 31 draws the i slide back after each operation, spreading the l levers at the same time` and such spring encircles a stem 32, attached to the slide, and is l confined on the stem between its head and a plate 33 at the rear of the frame 16. The slide is confined at the sides between guides 34: 34 and at top by the plate 35, the latter being omitted from all the views except Fig. 3 for clearness. Stops 36 are employed to limit the opening movement of the levers. Blocks 37 are secured to the frame 16 and have overhanging edges engaging the beveled side of the ends 50 of the stationary jaw, as seen in dotted lines at Fig. 3. These blocks assist by this engagement in holding the stationary jaw upon the plate.

`With the machine constructed as described the operation is as follows: The machine is positioned with the fence-wire lying transversely upon the ends of the stationary jaw or upon the blocks 37, as seen at Fig. 1, and with the body of the stay in the notch 2O and with the hooked portion thereof resting in the lower portion ofthe groove 25. Power is now applied to the slide, and the same is thereby urged toward the stationary jaw. This carries the incline 23 under the fencewires with the stay in the groove 25, and gradually forces the fence-wire back or beyond the plane of the abutment-surfaces 51. the bent portion of the stay moving along in groove 25 until it reaches the breast 2li. The continued pressure or movement by the slide now carries the point 13 until it closes the opening in the hook and securely holds the fence-wire. The bend 14 in the fence-wire is caused at the same time by the fact that the fence-wire is held at each side of the stay by the surfaces 51 of the stationary jaw, while the portion 14C is forced under that jaw by the slide. The bend 15 in the stay is due to the fact thata portion of the coiled part of the stay is carried back of the plane of the notch 20. The body of the stay is prevented from tipping or yielding to the pressure of the coiled portion thereof while the operation is in progress by the lip 26, so that the formation described becomes a matter of certainty. '1n fastening the lower ends of the stays the frame is placed under the fence-wire, and in fastening the upper ends it is placed over the fence-wire.

In the modification shown at Fig. 6 I aim to facilitate the imparting of the lateral bend to the points 13. and to this end the shoulders 30 are placed one in advance of the other instead of opposite each other, as in the other construction: and the acting end of the slide is permitted a slight lateral movement by locating the guide 34 on the opposite side of the slide from the forward shoulder a short distance from the slide. lith this construction the lever acting' on the forward shoulder 30 will tend to force the acting end of the slide over against-the guide positioned as stated, and thereby to carry the point 13 of the stay laterally.

The invention is intended primarily to be used by hand in attaching the stay to the fence-wires after the latter have been strung upon the posts; but it may be used in the manufacture of the fencing at the factory.

I claim- 1. The combination in a machine for attaching hooked stays to fence-wires, of a stationary arch or bridge-like jaw notched on its face to receive the stay, and a movable jaw consisting of the grooved incline 23 and vertical breast 24, and acting to close the hook in the stay, substantially as specified.

2. The combination in a machine for attaching hooked stays to fence-wires, of a stationary arch or bridge-like jaw notched on its face to receive the stay, and a movable jaw having an inclined projecting part adapted to enter under the stationary jaw, and avertical breast acting to close the hook in the stay, substantially as specified.

3. The combination in a machine for attaching hooked stays to fence-wires, of a stationary arch or bridge-like jaw notched on its face to receive the stay, and a movable jaw, and means whereby the movable jaw forces the coiled end of the stay back of the plane of the notch and thus forms the bend 15 in the stay, substantially as specified.

4. The combination in a machine for attaching hooked stays to fence-wires, of a stationary arch or bridge-like jaw notched on its face to receive the stay, and a movable jaw consisting of the incline 23 and breast 24, having formed in them a laterally curved or bent groove 25, substantially as specified.

5.
