Be it known that l, JAMES Karim DAL- I V Y v RAMi-m, acumen of the llnitec states, and borough of Manhattan, 1n the county and State of New iork, have invented a new and lmproved Beating-in Device I" for Looms, ol which the following is a full, clear, and or act description, this being a division. of the application for Letters Patent of the United 5 States for a pile fabric loom, Serial No. 289,563, filed by me January 4, 1905. i The object of the invention is to provide a l new and improved beating-in device which is l simple and durable in construction, very feetive in operation, and arranged to insure I a proper heating in of the weft and the pilei the beaten-in parts in position during the formation of the l following row of pile-warp-thread loops, and I to keep the pairs of ground-warp threads properly separated for the pile warp-thread l needles to pass between adjacent pairs ofl ground-warp threads. l 'The invention consists of novel features and parts and combinations of the same, 'as will he more fully described hereinafterand i then pointed out in the claims; l A practical embodiment of the invention l is represented in-the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the views.

Figure l is a side elevation of a pile-fabric loom provided with the improvement, and Fig. 2 is a cross-section of the same on the line22ofFig.l.

The beating-in device consists, of sets of curved arms, each set having two arms 0 and O secured on a transversely-extending shaft 0 journalcd at its ends on levers P, fulcrumed at their lower end at P on the main frame A of the loom. On the shaft is secured a worm-wheel Q, in mesh with a worm Q, mounted to rotatewith and to slide on the square end Q of a shaft Q, journaled at its square end Q ina suitable bearing formed on the u per formed end P of the lever P. The ot or end of the shaft Q is mounted to turn in a hearing A, carried by the main frame A, and on this end of the shaft Q is secured a bevel-pinion Q, in mesh essentially,

; connected with a lever it, fulmun lever ii" rests on the peripheral so.

with :1 her i tate mi On. the pe i, wheel Q ln s wheel Q rug of l: lievol H d or lormed a ratchet l a pawl R, pivotully red at it" end of the on ti 2 11min frame The free cam-wheel R in the form of an eccer cured on a shaft ll, receivins a rotary tion from the drivinggez of loom. .1 spring ii presses the pawl it to hold the same in contact with the ratchet-xvi;eel \Yhen the loom is operat the c imparts a swinging mot-ion to the lever F) i1, which by the pawl R nnparts an intermittent rotary motion to the ratchet-Wheel Q, and gear-wheel Q", so that the shaft Q is itermittcntl r rotated and this interniitt nt rotary motion is transmitted 03' the in Q and worm-w eel Q to the si.

sets of heating-in arms O and 0, held on the Y said shaft.

i The se ts of arms 0 and t) extend "tween adjacent sets of ground-warp threads (1/, and the arrangement is such that etise of the said arms always between jacent pairs of groundavarp threads a and a to prevent the Q'rounduvarp threads from be coming entangled and to hold adjacent 4 'rs of warp-threads sufi'icicntly far apart or proper entrance of the l-UIO t-fcrming devices of the loom. The arms 0 and G are also an ranged in such a manner that end of the outermost arm is always against the beaten in last by thisarni to prevent loosen ng of the weft .ast beaten in by the pulls exerted on the pile-warp threads to be f med into new loop after the loop is completed and. prc vious to and during the time a ting mechanism cuts the pile-warp throaus, s more fully explain ed in the application above re ferred to.

The lever P is pivotally connected by a link P with a bell-crank lever P, controlled by a suitable cam mechanism, to impart an intermittent swinging motion to the lever Pf, u to shift the beating-in device, and with it the worm-wheel Q and Worm Q, bodily during the time the arms 0 and O are rotated.

The operation is as follows: Who" at weft has been passed through the open shed, the

pile-warp threads are drawn tight around the weft; and-then the beating-in arms 0 and O arerotatedari'd moved bodily to the right, so that the advancing beatingerm 0 acts on the Weft 'to beat the same home, the beatingin device com ng to a stop as soon as the end of the arm 0 has reached a final boating-in position and the arms 0 0 having revolved L ,one' hundred and eighty degrees. When the 5 19' "beating-in device is again rotated'et the next operation of the loom, it causes the arm 0 to beat in the. following weft, and this arm 0 remains-in. the beating-in position against this Weft until the following operation.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. A beater-in device con'iprising a shaft, means for lntermittently rotating the said shaft, and sets of curved arms on the semi "shaft, each set of curved arms consisting of at least two arms ext-ending dir, metrically opposite each other, and one of the said arms extending between adjacent sets of ground- Warps.

2. A beatemn devlce comprising a shaft,

means for intermittently rotating the said shaft, and sets of curved arms on the said shaft, each set of curved arms consistingof at least two arms extending diametrically opposite each other, and one of the said arms extending between adjacent sets of ground- Warps and the other of the said arms being in engagement With. the Weft last beaten in during the time the beater-in is at rest.

3. A. heating in device for pile fabric looms, having curved arms, and means for intermittez'itly rotating the said arms, the end of an arm abutting against the fabric at the time the arms are at rest? 4. A pile-fabric loom provided with a rotating bcating-in. device, means for intermittently turning the said boating-in device, and means for imparting bodily movement to the said beating-in device in the direction of the length of the weave.

5. A beater-in for pile-fabric looms, comprising a shaft, n'ieans for intermittently r0.
