.10 Claims. (01. 189-188) This invention relates to lay construction for looms and has for an object to provide such a construction which is much lighter than present forms together with an increase in the desired rigidity in all directions, vertical, horizontal, and in torque resistance.

Another object is to provide such a construction which results in reduced inertia and vibration with consequential reduction in power required for operation and in wear upon the parts.

Another object is to provide such a construction in which the increase in rigidity, particularly in the vertical direction, at the ends of the lay, beneficially cooperates with the proper operation of automatic quill magazines for supplying the shuttles; and in which increased rigidity in the sense of resistance to torque stresses improves the operation particularly as regards the contact of the bumpers carried by the lay with the latch fingers of the quill magazines.

Another object is to provide such a construction which increases the accuracy in the aiming and flight of shuttles across the loom and in their reception by the shuttle boxes.

Another object is to provide such a constructio in which the usual raceway is not required, which not only simplifies the structure and reduces weight but also afiords opportunity for a shuttle which may be caught in the shed to fall through to the floor under the loom and thus avoid injury to the shuttle on the forward stroke of the lay.

Another object is to provide such a construction in which simplicity of design is emphasized and' standard forms of prefabricated structural elements are used, with consequent reduction in the cost of manufacture.

Another object is to provide such a construction which may be secured to the lay swords in standard and approved types of looms without requiring changes in the other parts of the loom or in its normal mode of operation.

A further object is to provide certain improvements in the form, construction, material and arrangement of the several parts whereby the above named and other objects inherent in the construction may be efiectively attained.

A practical embodiment of the invention is represented in the accompanying drawing, in which Fig. 1 represents an isometric perspective view of the lay construction associated with upper parts of the lay swords;

Fig. 2 represents an end view of the parts shown in Fig. 1, looking from left to right;

Fig. 3 represents a vertical section takenin 2 the plane of the line III-III of Fig. 1, looking in the direction of the arrows; and

Fig. 4 represents a vertical section taken in the plane of the line IV-IV of Fig. 1, looking in the direction of the arrows.

In usual practice the loom lay is constructed of Wood and iron and is provided with a smooth, level top surface to serve as a raceway for the shuttle in its flight. The construction is heavy and somewhat cumbersome, particularly with respect to the upper parts where, with a view to the attainment of rigidity, at least one heavy iron constructional element is embodied. This involves the necessity of considerable power for the oscillation of the lay in its beat-up function and generates a very substantial inertia in motion with the inevitable concommitants of increased injury in case of a loom smash" such as may occur in case of faulty shuttle operation, increased wear upon the parts, and increased liability to breakage. The present invention overcomes these previously existing disadvantages, attains the objects hereinabove recited,

and, in a general way, serves to improve loom operation and economizes in the cost thereof. Referring to the drawing, the lay proper is denoted by l and is composed of metallic tubing preferably of one of the lighter metals such as magnesium, aluminum, or one of the alloys thereof, although steel may satisfactorily be employed with a reduction in the extent to which the objective of lightness is attained. In the drawing this tubular lay is shown as circular in cross section but it may be of other cross sectional form, such, for instance, as square, oblong, or hexagonal.

The said lay proper is fixed to the swords 2 and 3 by a pair of metal channel section brackets 4 and 5, the edges of which are welded to the top and bottom of the tubular lay I as indicated at 6, I, in Fig. 4; it being understood that while these weld lines 6, I, are illustrated in the drawing only in connection with the fastening of bracket =4 to lay I, the bracket 5 is correspondingly welded to the lay.

The said brackets 4 and 5 are each adjustably fastened to the lay swords 2 and 3 by one or more bolts 8 which traverse open ended slots in the brackets and also pass through the swords; thereby permitting a certain amount of horizontal adjustment of the lay in order accurately to position it with respect to other parts of the loom.

Supports for mounting the shuttle boxes are provided in the form of metal pads which, like cured directly to the upper pads 9, ll, l3 and l5, 1

while the lower pads l0, l2 andl l serve as re-. inforcement at these points forerrhancingthe rigidity of the structure. There is no :complein the case of flange l9. This provides a very firm assembly for the upper part of the reed while permitting suitable vertical adjustment to accord with the particular weaving operation under way. Portions of the reed are shown in Fig. 1 and indicated 34, 34.

In .the foregoing description-it has been men- "itionedithat there is adfiniteadvantage in have mentary lower pad for the-upperzpad 1:5,:but2the latter is formed with an angular aweb IB' -thatr supplies the necessary rigidity; and said pad also has an upwardly extendingabutment I! at its outer extremity which serves to prevent outward movement of the long upper shuttlebox at this end of the lay, while permitting the usual i vertical adjustment -thereof sfor accommodating the loom to the weaving .of'fabrics-..ofvarying :pile heights. There is no .occasionlforsuch a {provision at the opposite rend rof the lay 7 because the upper shuttle box at that-point is theshorter \.one and .is held in .p.osit-ion .by its. fixture to =.the loweri box. =Any: suitable -fasteningelements may :be employedior securing .the boxes to .the pads, and wehave :foundboltsr or cap-screws to be satis- :factory. 'Il1e:boxes and.the fastening elements are not-shown.intheidrawing because they form :no part of .the,p11esent invention, which isdirected to the layconstruction.

The lower reed :slot is marked l8.and;itcon- :sists of a metallic-channel bar which; isprovided 'with a laterally extending ,fiange .I9 along its :upperrear edge. Theends of :thesaid-reed :slot :are .fastened; preferably by welding, to .the brackets 4 andsfi and .-its :intermediate 2portion iis secured i at intervals .to the .tubular elay -l .byra

rseries=of channel sectionpads 2i}, 2|, 22, which are similar to cbrackets-kandfi and:are.-welded-..to thelay proper ii at its topand bottomlasindimated-at 23, :24, in Fig.3, -.while-the.said reedslot is. likewise welded .to the top-.of .the :said pads -20, v2!, .22. This union of the parts sjustidescribed yprovi'des :ior .a :high 1 degree of ;rigidity :and .re- .sistance to strains, which is increasedxto ,a .still higher degree by the flange 49, that .-not only istrengthens the lower :reed slot, but -.also braces ithegparts by reason of :the fact .that its .ends firnily abut the inside-edges .offthelay swords 2,3, :asclearly: shown. in Fig. .1.

The upper reed :slot .is .denoted by 2.5 and -.it is :a duplicate -,of the .lower slot .-l8 though -.it .is, of course, reversed in position so that its channel ropens'downwarcliy 'while .thatof (8 opens :up- -wardly. -1Tli628Il-C1S-Offiih9 said .upper slot 25.are secured, by-welcling, to theunder side -.of ca jpair of metallic rchannel sectiombrackets 26,21, avhich are provided \with bolts -28, .28, which ex- .tend rearwardly from the bracketsiand traverse :slotsr29, -29, fashioned inithe upperrextremities of the .layswords. .A reedecover -flfl, which-consists of a metallic tube of any suitablecrosssec- I -..tional-shape,.cir.cular being shown -andis prefereably composed .of one .of the lighter metals 'as ,mentioned in connection with the lay 3|, rhasits -encls mounteddn brackets .26, .2-1, .theedges -.of which are welded t the top.and:bottom.of reed scoverfill asindicatedatfi l, 32. .It .will.also;be..un- Qderstood that the fiange on the upper lree'dslot 25, which is shown in Fig. '3 and marked '33,.lies .ibetween the swords 3, ,with-its. ends firmlyiabut- .of light metal.

ing the lay proper I and reed cover 30 composed This is of prime importance because they are the largest elements of the upper lay construction and a substantial reduction in .their weight leads=to a major reduction in the -.total Weight .of the moving parts, with corre- ,-.-sponding.decreasein power required for operation and in inertia which must be overcome at the -end .of each oscillation. However, it should be 'adcled'that itis desirable that the other parts of the construction (except the lay swords which are usually composed of wood) be likewise made .from light metal wheneversuch material suit- .able to the purpose is available.

It will .be evident that the constructionherein :shown and .describedis calculated to attain the -.objects.recited at the outsetof this specification and it will also be clear that the structure is -easilyfabricated and is also readily susceptible .torepair or replacement of any worn or injured apart or parts. In this general connection it should be noted that the rigidity imparted tothe .endportionsofthe lay I permits the lay swords .tobepositioned relatively close together and all .the shuttle .box supports or pads to be located outside theswords. This enables a decrease in .theQlength of the wreedcover 30 with associated .re'ductioninits weightand increase in its stiff- ..ness.

We desire ,it to be understood that various changes may be resorted to in the form, construction, arrangement and material of the several parts without -departingfrom the spirit or .scope of the invention; and hence we do not intend vto be limited to detailsherein shown or described except as they may be .includedin the .claims .or berequired bydisclosures of the prior art.
