IMPROVEMENT IN `MACHIlIIl'I-Il FOR MAKING WIRE HEDIDLES.

The Schedule referred to :in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that we, PETER PHILIP and FRANK- LIN PHILIP, of Stockport, in the county of Columbia, and State of N ew York, have invented a certain Improvement in Machines for Making Heddles; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings, making part of,l this specification, in whichf Figure l is a plan viewof the machine.

Figure 2 is a longitudinal vertical-section thereof, on line arzt, iig. 1.

The same letters are used in both igures in the designation of identical parts.

Our invention relates to a machine for making heddles for looms; and our improvement consists in combining, with the ordinary mechanisrnithcreof, a lever provided on its outer end with a point or tooth, and so arranged upon one of the twisting-jaws, that the tooth shall, at the beginning of the operation, be thrust between the wires close to the eye-forming jaws, and` press or crowd the twist toward such forming-jaws in order to make the angles of the eye, at the junction ofthe wires, less acute than they can be made without such tooth, and so that, as the twisting progresses,

such tooth shall be gradually withdrawn iiom between the wires; all as will be more fully set forth hereinafter. To enable those skilled in the art to make and use our invention, we will proceed to-describe its construction and operation;

In the drawings- A represents the bed-plate or frame-work of the machine, having suitablestandards orblocks, A1 and A2, formed upon or secu-red to it, in which the mandrels have their bearings, there being usually two of them employed, arranged opposite to, and in one axial line with each' other. In front of the block A1,'a pedestal, A, is arranged upon thebed-plate, to form a support for the eye-forming jaws which are pivoted in the upper portion thereof.

Through the centre ofthe mandrel B, a hole of sufficient size is bored, or otherwise formed, through which the wires are passed; and deep longitudinal grooves are formed in them to receive the holding and twisting-jaws. u

C C and O C represent the holding and twistingjaws, constructed and arranged in the mandrel in thev ordinary manner.

-D represents the sliding collar by which the jaws are opened and closed. It is partly embraced by a fork, El, lying ina groove therein, and which is actuated hy a reciprocating rod, E, upon which it is arranged in connection with a spring, E2, in the manner shown.

E3 and E4 represent the eye-forming jaws pivoted in the pedestal A, The jaw E" is provided with a projection upon its upper face, around which the eye of the heddle is formed. A

A more specific description of the above-enumerated parts is deemed unnecessary, as they are Well-known derices, and form no part oi" our present invention, and may be sufliciently understood by referencerto the drawings.

. Heddles, as heretofore constructed by the old-style machines, had more or less acute angles at the crossing of the wires, which is an objectionable feature, because they are liable to catch the warp and break it, or check the steady progress of the ythreads whenever a knot or unevenness is encountered. Sometimes the eyes areformed by spreading of the wires subsequent to their being twisted together, whereby'the angles may be made `less acute, but they are always more or less roughened and marred in this way.

To obviate these objections, we employ a lever, F,

I.hingecbto one of the twisting-jaws C', and provided, at

its forward end, with a point or tooth, F1, which is thrust between the' wires, between the twisting and eye-forming jaws,for the purpose of crowding or pressing the twist toward the ,saidformiug-jaws, to give the desired shape to the eye, as Well as to take 4 up slack wire tov be used in forming the twist, so that vthet-wist may be made very tight without unduly straining and injuring the surface ofthe wires.

The lever F is so arranged on the twisting-jaw that its pointll is retained between .the wires ot' the hed? dle until the twist is sufficiently pressed against the forming-jaws, and sufficient slack taken up, when it is withdrawn. The lever is arranged on a reduced portion of one of the twisting-jaws pivoted upon the same pin on which the jaw turns. Its forward armv is pro-y vided with the tooth or point F1, as above stated, and itsother arm being extended to just beyond the inner face of the block'A;1 in a nearly horizontal direction, is turned abruptly outward, terminating near the bend ofthe twisting-jaw, as shown.

g Where this short end, which is marked F2 in the drawings, joins the main portion of the lever, .a spur ,or'projectioln f, is formed, which is engaged by a catch or hook, G, the angled point of which is so constructed as to be capable of impinging against the horizontal edge of the spur Liu order-to press the point F1 between the wires, as also to press against the `vertical edge of said spul', to keep the point out of the wires. The catch is pivoted at its outer end to the twistingjaw, as shown, and is actuated by the spring G. I

H is a wedge-shaped` piece of metal fastened tothe inner side of the block A1, and in such apost-in, that as the mandrel is revolved, the forward edge otftlie part F2 of the lever F shall come in contact with such wedge or incline, and thereby the lever gradually turned, so as to withdraw its tooth from between the wires. When the lever has been thus turned, its spur f has escaped from the angled point of the catch, which now impinges against the vertical edge of such spur, holding the lever in such a position that the upper edge of its forward arm vis ush with the surface ofthe mandrel, so that, on opening the jaws, it will be forced against the bearing of the mandrel, and turned suficiently to cause the point of the' catch to again hook under the spur f, and thrust its tooth Fl again between the wires.

Having thus described our invention,

What we claim, and desire to secure by Letters iPatent. is

1. In'combination with the twisting-jaws of a machine for making heddles, a point or tooth which is first thrust between the wires for the purpose of crowd ing the twist toward theeye-forming jaws, and also for the purpose of taking up slack wire to be used in formingy the twist, and then gradually-:withdrawn from between the wires, substantially inthe manner set forth.

2. The combination of the twisting-jaws C', lever F, with point or tooth F1, hook Gr, spring G', and incline H, all arranged to operate substantially in the manner set forth.
