To all whom 'it may concern.'

Be it known that l, JULIAN S. encens, a citizen ot the United States, and resident ot Springfield, in the county ot lllindsor and State of Vermont, have invented certain new and useful Improvements in Bag-Stock Feeders, ot whichthe following is a specification.

This invention relates to rag feeding niachines of the type disclosed in Letters Patcnt of the U. S. No. 1,258,222 dated March 5, 1918, or any type of feed apparatus tor feeding `rag-stock, wool or other similar material to a picker or other machine by which the material is'to be treated.

Heretotore it has been customary to use a comb for straightening out, opening or leveling the ra g-stock or other materia-l that is being carried up on the ieed apron to be delivered to the working machine, but such combs have been made in the form ot a saw tooth or similar to the blade ot a mowing machine thus presenting` a series of shaped flat teeth extending in a single plane nearly parallel to the plane of the feed apron or conveyer. Combs ot this type do not perform the opening and leveling operation in a very efhcient or satisfactory man ner, and it is the object ot the present invention to lprovide a comb for this purpose which while being simple in construction shall be more effective in opening lumps or bunches of material and laying the material substantially parallel to the travel ot the apron so as to produce a more uniform feed or delivery ot the material or rag-stock to the operating machine.

To this end the invention comprises the combination with a feed apron or conveyer of a comb embracing` substantially a longitudinal supporting member and a series of thin blades set edgewise transversely ot the supporting member at suitable intervals apart in parallelism with each other so that their thin edges may engage the iproaching rag-stock 'carried by the spikes of the apron and properly distribute and level the ragstock on the conveyer to secure a substantial uniform delivery oit the material.

This and other features of the inventionwill be set forth in this specification and will be defined in the claims annexed hereto.

In the accompanying drawing I have illustrated a simple and convenient construction embodying the principles of this invention, so much ot the feeding device or conveyer being show is necessary'to an understanding of the present invention.

ln the drawings- Figure l is a perspective view showing the operation ot the conveyerand related parts in combination with the distributing or leveling comb. i

Fig. 2 is a vertical cross section through the comb showing a methodot fastening' the blades to the supporting bar.

F 8 is a front view showing two adjan cent blades secured to the supporting inember. l

The type of the feed apparatus shown in the drawings is similar in construction to that shown in .our above-mentioned patent. l'n this case there is shown an assembled portion of the 'feed apron or slatted conveyer a with a part of the supporting trame work a and the projecting` spike bars a5 which engage the rags, wool or other substance which may be referred to under the general term rag-stock l. @n the supporting` brackets b of the trame is mounted a rockl shaft o which is oscillated through a small arc by means ot the crank b2 connected with the pitman 53 so as to produce an oscillation of the comb toward and away from the spiked conveyer on whose points are impaled or caught the rag-stock which is being ted to the operating machine.

The comb itselt comprising a su rportinggg member c in this case shown has a. longitudinal angle bar extending across the feed apron.

et suitable distances apart along the supporting baro, forming the back or Jframe of the comb, are formed transverse slots in which are inserted thin flat blades which are set edgewise transversely et the supporting member so as to present their thin edges to the approaching rag-stock.

As best shown in 2 the blades are shaped to a downwardly projecting point and have their front edges c3 somewhat sharpened and also preferably slightly concaved so as to cut or tear the material when it is hunched too tightly to be easily opened without such cutting action. Y

The blades o may be secured to the supporting member c in any suitable manner. However, in the drawings we have shown the upper portion ot the blade bent laterally to 'form an ear or flange `c2 through which a fastening bolt or screw may be passed to secure it to the supporting bar. With this arrangement also the slots 010 form an additional support for firmly holding the blades edgewise to the worlr and .maintaining` them in proper operative position.

The comb is adjustably mounted in opera-.

kpreviously used. rl`he edgewise arrangement of the blades to the stoclr not only permits the cutting through of tightly wedded lumps of material but the arrangement of the blades more effectively secures a straightening out of the material in lines substantially parallel with the direction of the feed.

What we claim is:

.1. ln ama-chine for feeding rag-stock or the like, the combination of atraveling feed apron provided with a series of projecting spikes for engaging the rag-stock and conveying it to the delivery end of the machine7 a cooperating distributing comb comprising a cross-bar supported above the spiked apron and having a series of depending blades set in parallelism edgewise to the feed of the apron and secured to said crossbarat spaced intervals so as to oppose their edges against the traveling rag-steelt engaged by the spikes in order to distribute the rag-stock evenly as the apron passes beneath, substantially as described.

2. ln a machine Yfor feeding ragstoclr or the like, the combination of a spiked feed apron arranged to feed the stock to the delivery end of the nnchii1ev an oscillatory distributing comb supported in proximity to said apron and comprising a transverse blacle-supporting` bar, and a series of blades secured at spaced intervals thereto 'in parallel relationship edgewise to the advancing stock` whereby the thin edges of the blade engage the rag-stock held by the spikes and lay it in parallelism lengthwise of the apron, substantially as cescribed.

3. A. comb for a rag-stock feeding machine embracing in its construction a trans-A versev bladesllppoftng bari a Series. of

Ymounted in spaced blades secured theretol with their blades extending edgewise in parallel planes with the travel of the apromand means for supporting said comb fromY an oscillatory shaft whereby the blades may be movedV edgewise to anc fro against the rag-stock carried by the apron and lay it in parallelism lengthwise of the apron, substantially as described. l

d. A vcomb for distributing rag-stock or the like over the apron ofa rag-stock feeding machine embracing a transverse bladebar, a series of flat thin edge blades secured directly to said bar inrposition to present thin cutting edges to the approaching ragstoclry' and means for suspending said-bar to permit oscillation of the comb in prox* imity to the surface of the apron, substantially as described.

5.` A comb for a rag-stock feeder embrace ing in itsconstruction al longitudinal supporting .member providedlwith a series of properly spaced transverse slots, a series of thin .blades inser ed in said slots to liel in parallelism with each other and secured to l said supporting member, substantially as described. i

6. A comb Vfor a rag-stock feeder embrac-Y ing in its construction a longitudinal angle bar vprmiided with transverse slots, a series of teeth inserted in said slots and comprising thin parallel blades each formed with a laterally extending lug and affording means for bolting the tooth securely to said angle bar.

7 A combfor a rag-stock fee-der embracing in its construction a lateral supporting member, a series of thin blades formed with laterally projecting ears and fastening Cit means passed t irough said cars'to secure the 100 individual blades firmly to said supporting member in lnnallelism with each other transversely of the supporting member, sul stantially as described. f

8. distributing comb for a rag-stoel; 105 feeding machine embracing in its construction a blade-si Jorting bar adapted to be aposition to the apron of the feeder, a series of thin blades set edgewise ransversely of'saidblade-barsoas'to 110 lie in parallelism with the travel of the apron and rigidly secured to said blade-bar, the forward edges of said blades being sharpened and curved to tear apart and cut approaching bunches of rags, `substantially as described.

lnwitness whereof, l have subscribed the above specification.
