WILLIAM V.' GEE, 'OF PHILADELPHIA, PENNSYLVANIA.

temeva-Maurin Looms.

S pecification formingpart 'of Letters Patent No. 164,600, dated September 1.15711; application filed July 11, 1874. i

'To all whom it may concern:

Be it known that I, WM. V. GEE, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and valuable Improvement in Loom Attachment; audI do hereby declare that the followingisafull, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification, and to. the letters and iigures ot' reference marked thereon. 4-

Figure 1 of the drawing is a representation of a top view of my loom attachment. Fig. 2 is a side view of the same.

This invention has relation to looms which are especially designed for -weavinglcarpets, wherein a reciprocating hook and a recipro cating 'nger areemployed, instead.4 of a shuttle, for carrying the filling or weft across the shed, substantially as described in my Letters Patent dated October 31, 1871, and' numbered 120,510.

The improvements which I have made consist, mainlyin novel devicesfor knitting a selvage on one edge of the carpet, and drawing .the loops tight, using for this purpose a reciprocatin g latch-needle; also, a device for casting oi the loops, a device for regulating the tension on the loops, and' a device for removl in gl the loops from the hook which throws'in the filling or weft, as will be hereinafter ex' plained. It also consists in a blade or tongue,

ywhich is arranged below the needle, and secured to the lower jaw of the temple, which blade is designed as a means for guiding the outer supporting warp-thread, and keeping it straight, and at the same time `holding it firmly while the loopsv are being formed. It also consists in combining with a reciprocating needle-bara gravitating-arin, which is connected to a shifting-rod by a crank and link', and which lies upon said needle-bar as long as the selvage knitting proceeds properly, but should a loop break the needle-bar will drop, and cause the loomto stop running, to

. allow the proper repairs in the fabric to be made.

rihe following isa description of my im-. provenients i Inthe annexed drawings, A designates the frame of a loom-temple, the broad portion of which is rigidly but adjustably bolted upon the breast-beam, and the narrower portion of which has a raised serrated jaw, a, formedon it, which serves, in connection witha pivoted spring-jaw, b, to hold the carpet under proper tension on-one side of the loom. The jaw b is pivoted to the trame A, and constructed with an arm, b', depending from its hinged end, which arm is struck` by the lay when moved back. The lower jaw of this temple is held up against the upper jawby means of a'spring, (not shown in the drawings,) and this lower jaw is provided with holding-spurs c, which serve as an additional security in holding the carpet. B designates a plate, which is perpendicular to the plane of the frame A,

'and which is rigidly secured to this 'frame a little oblique to its length. This plate B is constructed with two slots, d d', through it, in which work two guides, e e', that are fixed into one side of a needle-bar, D, carrying on one end alatch-needle, f, such as is commonly used in knitting-frames. ,The slot d is slightly curved, so as to .give a dipping motion to the needle as it advances to receive the weft-loop,

and a rising motion as it recedes to form the loop. The rear end of the rear slot d is made quite broad vertically, for the purpose of allowing the rear end of the needle-bar to drop should a loop break or the needle fail to take a loopedend of the weft. The needle-'bar D receives a reciprocating motion from a cam, C, acting through the medium of an angular lever, U1, and a connecting rod, C2. `(Shown in Fig. 2.) Above the needle-bar D, and pivoted to the plate B, is an arm, E, the free end of which rests upon the par D, and is held up therebyas long as the needle f is looping properly; but should a loop break the outer end of the bar D will drop, and cause the free end of arm E also to drop.- Arm E is connected to a crank, g, by means of a link, g1,

which crank is fast on one end of a rock-shaft, g2, suitabiy'connected to a beltshipper for a main drivin g-pulley. Now, it will be seen that when arm E dropsthe shaft g2 will receive a motion about its axis, thereby shifting the belt and stopping the loom. Any other suitable device may bc employed in connection The front end of the bar F is curved do.wn-

ward past the upper jaw of the temple, and on. the outer side thereof, so as to extend a Ilittle in advance of the needle, when tllelatter has been drawn Vfully back. It is around the curved endA of the bar F that the' loops are drawn' tight, during which operationthe spring S will allow the bar to yield more or less, so as to form a tight selvage. The front end of the needle-bar D has secured to it a curved loop-stripper, G, which does not extend as far forward as the hook of the needle f,fbut which does extend belowT this needle, and is notched at i to allow free play to a reciprocating hook, as shown in my patent above referred: to, which takes the weft from the reciprocating linger, and carries it across the shed. The object of said stripper G is to-strip the loops of the weft from said hook after-the latter has terminated itsouter stroke. J designates a guide, which is made of thin metal, and secured to theouter side ofthe lower or movable temple-jaw. This guideJ is thin enough to pass through lthe reeds While beating up'the weft, and the front end of this guide rises above the plane of tlic lower jaw, so that it (the guide) receives on its outer side the outer supporting warp-thread, and serves to firmly hold the saine while forming the loops and beating,` up the weft. Guide J will thusenable me to make a straight knitted edge, and to draw thev Iand for the purposes set forth.

4. The spring yielding bar F for holding the loop, curved as described, and operating in combination withthe needle j, substantially as described. l

' 5. The guide J upon'the templefjaw b, arranged and combined with theA selvage-forming needle f, substantially as described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

' -WILLIAM' V.` GEE.
