To all whom it may concern: r Be it known that we. JA'MI'IS'llARIJNG and i RALPH llamas, residing at Rosegrove. near Burnley, in t'he county of LaneasterJ 5 England, have inyent'ed eertain new and useful improvements in ,-\utoniati(" \Vet't- Replenishing Mechanisnt ot- "Looius lor weaving; and we do hereby gleelare the fol 'lowing to l'lt: a full, clear," and (Kart de-" scription of the invention, suoil will enable others skilled in the art to whieh it appertains to make and usedhe same.

This inventiom-relates to pirn hoppers of automatic looms ot' the type in which. upon the exhaustion or breakage of the weft, the (10p or pirn is ejectedfrom the shuttle and. a' new cop or 'pirn from a hopper or magazine inserted therein. According to our invent-ion. t'he upper 2 portion of the pirn" liiipper,'whieh is preferuhlyofsurh a ,eapaeity to hold, tvhen .rlillecl, a days sppply ot';pir.ns and is-eapahle of attaehmentfto.and detaehnient firom the Tower portion of the hopper, (:olnprises a Vertieal spindle carrying a sleeys'e provided with hooks or the like ear'h' adapted to en .gage the weft end o'lon! otithe pirnsi'the number of the said hooks in sueh ease.

By this means the detachable portion of thehopper ran he tilled with pirns, and the weft ends ot sprlr pirns placed in engagement. with the hooks, say 'in a.

extent of one tooth, overcoming the resistance ot the spring brake 30 acting on the brake wheel 31. ()n the same spindle 21 is a spur wheel 3'. gearing with a spur pinion 33 mounted on ashort stud on the back of the hopper 2, on which pinion 33 is an cecentric pin 34 connected by a link 33 to a lever 36 secured on the spindle 3'2. ()wing to the eccentricity ot' the pin 34, the partial rotation of the ratchetwheel li thus causes the lever 36 to rise and tall alternately, and the spindle 2'2 amt cams thereon are thus rocked alternately to right amt lett.

()n the spindle t? is a loose sleeve 37,

lotted vertically so that it can freely pa s the rails l i. amt lt'itl which sleeve is pro- \idcd with books 38, each adapted to engage the end-ot the weft on one of the pirns. (in the other side of the sleeve are notches or recesses 35 opposite every second book. these notches being adapted to be engaged by the -spring catches 40, 41. The plate 42 secured to the rail 160 which is also secured to the I bracket 14 carries a pair of brackets 43, -t-t,

through which the spring catches 40,41 work freely when reeiprmrated in opposite directions by the lever 45 pivoted at 46 and connected to the arm 19 ot the lever or bent rod 30, the said spring catches being slotted or recessed to engage the said pivoted lever.

Close to the rear end of the lever .20 is 'l'astened an inclined bar 47, so arranged as to l'orm'with the inclined back of the lever itself a slot through which passes the level arm 36, which, as before mentioned, has an alternate rising and falling movement. The inclination ot. the slot causes this movement -to he converted into an alternate backward and forward movement ot the arms to amt 19 through the bearing 17, and the consequent rocking of the lever 45 at each stroke discngagcs one of the spring catches -It), 41, from a notchtlf), allowing the sleeve to drop so that either the same notch or the notch above is engaged by the'other spring catch; that. is, if the catch 40 is disengaged, the catch 4t engages the same. notch, but when the catch 4-1 isdisengaged, the catch 40 ens gages the notch above, so't'hatthe sleeve falls a distance equal to the pitch of the books 38 at each reciprocation of the spring catches. Guides 48 and 49 are provided to guide the weft between the pirns and the hooks 38. The detachable-hopper 50 (see Figs. 5 and has vertical compartments 3' and 4, the

outlets of which are of similar size and shape to the inlets oi the compartments 3 and 4, and is provided with a vertical spindle 51 supported by rails 52, At the rear of this hopper is a cross-bar 54 having arms 55, 5G, capable of sliding in brackets 57,58. ()n a bracket 50 is a tlat spring which presses on the crossbar, and normally holds it in the position shown in Figs. 5 and 6 with the end 56 ot' the arm 36 in contact with the spindle 5t and supporting the sleeve 37. Projections (3t, (32. on tlictrl'ossbai pass through slots at the back of the hopper, one of such projections entering each compartment and serving to retain the pirus in position, the'lowest pirn of each stack resting upon the projection in its respective compartment.

The bracket 5!) forms a socket in which registers the upwardly extending bolt.63 0n.

the lived hopper (shown in Fig. 1) and on this bolt't33 is a wedge or other projecting part. tt-t. When thesockct is being passe over the, bolt N3. the wedge 64- engages and presses outwardly the crossbar 54-, drawing the projections (31, ('12-, on which the pi'rns normally rest, out of the compartmentsof the detachable hopper, thereby allowing the said pirns to drop on to the pirns,if.any, contained in the lived hopper," or, if there are no pirus in the lixed hopper, to the bottom thereof on to the cams 23 and .24. At the same time the arm 5t? is by tlieoutWard movement of the crossbar 5t withdrawn from supporting the sleeve 37 on the spindle 5t, so that the said sleeve drops on to the top ot the sleeve, it' there be any such sleeve, on the spindle 15, or, if not, to the bottom of the said spindle, where the aforesaid spring catches engage it. The top of the spindle 15 may be provided with a key-or projection which registers in a recess in the foot of the spindle ":itwlien the detachable hopper is placed in position.

The action ot the apparatus is as follows: Assuming the lived hopper 2 to be empty,

the spindle to clear, the lever 36, ohms 23- -and it. and spring catches 4t) and 41, all in he positions shown in Figs. 1 to 4, and the detachable hopper 50 (which may be of any desired height) full of pirns with their weft ends over the hooks 38 on its sleeve 37,.the

hopper 50 is placed on top of the hopper 2 with the spindle 51 resting on the spindle t5; the wedge (it presses out the crossbar 54,

withdrawing support from the pirns, and

from the sleeve, which drops until the catch 41 engages the lowest notch 39. 'Those pirns in the com|mrtuient 4 fall. down the coinpa rtmeilt 4 until the lowest pirn is stopped cam 23. Upon the projection 26 on the lever 25 being struck by the pn'n carrier and the lever I oscillated thereby", through the connections 28, 29. 32. S rand 3.7, the lever 36 is lifted. The lever it) rocks the lever 45, withdrawing the catch tl. and the sleeve 37 drops till the catch t0 engages the next superior notch 39. The spindle is, by the aforesaid litting ot the iever Z36,

turned in the direction of the arrow in Fig. 4, so that the lower member of the cam is withdrawn from under the lowest p'iru in the compartment 3, which irn therefore passes through the outlet 13 into the pirn carrier, the upper member of the said cam interposing between the said pirn and the next pirn in the same compartment. The earn 2% is simultaneously rocked to release the nose of the pirn which had been resting on its horizontal upper edge. At the same time the lowest .pirn in the compartment 4 passes the receding upper member of the cam 23 and is received on the lower member thereof. h v

At the next actuation of the lever the pinion 33 again makes half a revolution. the lever 36 is lowered, the cat-ch tOis retired and the catch 41 enters the notch in the sleeve 37 which has thus been disengaged, and the rocking of the cam 2 enables the lowest pirn to be taken from the compartment 4. In like manner th'e'pirns are taken alternately from one compartment and from the other,'until the detachable hopper is emptied and the sleeve' ll' falls off the spindle l5'into stand or iirccptacle"plhced tii receive it; or, if the detachable hopper be removed when all its pirns have entered the fixed hopper,-and full detachable hoppers successively substituted, pirnwill follow pirn and sleeve follow sleeve as long as the loom continues weaving;

It will be observed that. there are two stages in the descent ofthc lowest pirn in each com 'iartment, between which it is retained within the concave side of the cam 23, the object of this arrangement. being to prevent the exit of more than one pirn at a time. a

We may arrange, it found cxptalicnh'for two weft ends to be engaged by one hooie on the sleeve, instead of for each book to engage the weft end of one pirn as above described.
