' "To all whom it may concem:

Be it known that I, O'r'ro W. SCHAUM, a citizen of the United States, and a resident of Philadelphia. county of Philadelphia, State of Pennsylvania, have invented new and useful Improvements in Looms, of which the following is a specification.

The invention relates to looms and particularly narrow-Ware looms employing two or more banks or rows of shuttles arranged with the rows one above another.

In my Patent No. 786,237 granted March 28th,-1905, andin my Patent No. 803,511

granted October 31st, 1905, there is shown a narrow-ware loomvof the type just referred to. In this class of looms it is advisable that any of the several rows or banks of shuttles be positioned with respect to the open shed of the loom so that the yarn or threads carried by said banks or rows of shuttles may 'be woven in the fabric.

In looms of this type there is employed a lay-beam or a batten-beam as it is called that extends longitudinally along the forward part of the loom and the several banks of shuttles extend along and are located above said beam. The batten-beam and the banks of shuttles associated therewith reciprocate horizontally and transversely, or in other words forward and back. The banks of shuttles are also capable of being moved ver tically, relative to the batten-beam, and are mounted so that they can be moved horizontallv and longitudinally when depositing.

the threads.

The present invention is directed to a new construction for supporting the battenbeam and for maintaining the banks of shuttles, when in any one of the desired positions, in ten-beam.

The novel features above referred to as well as other novel features are hereinafter specifically described and definitely pointed out in the accompanying claims.

As illustrating a specific form of the in-v vention reference is made to the accompanying drawings forming a part of this specification,in which drawings,

Figure 1 is a partial vertical sectional view I showmg a portion of an' end or transverse frame, a lay-head, and some ofthe parts for supporting and actuating the lay-head.

Fig. 2 is a partial front view or elevation showmg a portion of the end or transverse proper position relative to the batframe, a portion of the lay-head, and some of the parts for supporting and actuating thelayead.

Fig. 3 is a vertical sectional view of the lay-head which com rises the batten-beam, the shuttle carrying Frame and a casting for supporting said batten-beam and frame.

F g. 4 is a sectional view of the lay-head casting wlth certain attached parts omitted. This 1s a view of the casting when taken as on the line 4-4 of Fig." 1 looking in the direction of the arrows.

Fig. 5 is a view taken as on the line 55 F1g.' 3 looking in the direction ofthe arrows.

Fig. 6 is a perspective View of a detail whic is on the shuttle carrying frame.

The lower portion of an end or transverse frame-1 of the loom is clearly shown in Fig. 1. The lay-head of the loom is designated by 2 and is shown as being provided with four rows or banks of shuttles, a, b, c and d.

The. lay-head comprises a batten-beam or lay-beam 3, a frame 4 carrying the shuttles, mechanism associated therewith whereby the shuttles can be carried in said frame and can also beoperated, and a lay-head casting 5 the function of which casting will here;

inafter more fully, appear. As the battenbeam 3 and the-frame 4 is each a comparatively long member therea're employed a plurality of these castings, at least one at each end of the machine, and there may be intermediate castings if required to impart rigidity and strength to the associated members. Each lay-h1ead casting 5 is carried by parallel links 6 and 7. The lower end of each of these links is pivotally mounted upon a suitable bearingcarried by the frame 1 and in the form shown this bearing is provided on a member 8 which is secured to the end or transverse frame 1 in any suitable 1 manner. The upper end of the'link- 6 is piv- 'otaHy connected at 9 to the lower forward portlon of the casting 5 and the upper .end

of the link 7 is pivotally connected at 10 to the lower back portion of the casting 5. This" casting 5 'is shown more in detail in Fig. 3 in which figure it will be observed the batten-beam 3 is secured in place upon the casting by'means of a bolt 11. Vertical ad- 'justment of this batten-beam. is attained through the medium of an adjusting screw 12 which is locked-in place by means of a nut 18. g A depending leg or spacing member 14 extends from the under side of the batten-beam 3 into a socket 15 and rests upon the upper end of the adjusting screw 12. At the rear side of the lay-beam or batten-beam there is secured in any suitable manner a plate or member 16. This plate or member is also secured, when the batten-beam is in adjusted position, to the upper end of the casting 5 by means of bolts 17, clearly shown in he shuttle carrying frame 4 comprises a pair of vertically spaced longitudinally extending beams 18 which are connected to gether by means of vertically extending tie members 19 whereby a comparatively rigid frame construction is formed. This frame 4 is located above and extends along the laybeam or batten-beam 3, as previously stated. The casting 5 comprises a horizontally and transversely forwardly extending portion 20-the portion in which the adjusting screw 12 is located-and a vertically extending portion 21, both of which portions are in tegral with each other or in other words constitute a part of the same casting.

The portion 21 extends above the top of the batten-beam 3 behind the frame 4 just described and serves to receive any backward thrust which is imparted to it through the parts which will be hereinafter more fully described. In other Words, the conand 24 in the casting 5.

struction is such that the forces necessitated by the moving of the frame forward and backward are all absorbed by this casting.

The frame 4 has been heretofore described as being vertically movable relative to the batten-beam. This is taken care of by means of a vertically extending guide-member 22, preferably made of cold rolled steel, which is carried in sockets or drilled openings 23 This vertically extending guide-member 22 can be readily removed by lifting it out of the position shown. The frame 4 is provided at its top and bottom with ear members or lugs 25 and 26 which have a sliding engagement with said guide-member 22. The ear mem bers or lugs 25 may be referred to as the vertically movable guide-members since they move vertically along and relatively to the vertically extending guide-member 22 which is a relatively stationary member. These ears or movable guide-members are shown in perspective in Fig. 6. As constructed the lower end of the vertically extending. guidemember 22 rests upon the bolt 11 which serves as a stop or support for said guidemember. The lay-head casting 5 is cut out at 27 to permit vertical movement of the bolt as the batten-beam 3 is vertically adjusted.

The batten-beam 3 has heretofore been described as resting upon the top of the spacing member 14 which engages the upper end of the adjusting screw 12. Pratt tically any desired height of adjustment of the batten-beam can be attained by the employment of the spacing members 14 of the proper selected length. The lay-head casting may be considered as of L-shape with the lower or transversely, extended portion of the L extending forwardly under the batten-beam. The upwardly extending portion' of the L, as previously pointed out, extends upwardly past the batten-beam and behind the shuttle carrying frame 4; At each end of the lower transversely extending member or portion there are provided drilled openings 28 and 29 through which pins 30 and 31, at points 9 and 10 heretofore referred to, pass whereby the lay-head casting is supported by the upper ends of the. parallel links 6 and 7. This casting also has another drilled opening 32 through which passes a pin 33 that connects a link 34 which extends from the mechanism that moves back and forth the lay-head casting and associated parts, or what may be referred to as the operating mechanism.

The mechanism for accomplishing this movement is old and well known in the art and hence is not further described.

During the normal operation of the loom it is frequently desirable to raise and lower the frame 4 carrying the shuttles whereby any particular bank or row of shuttles can be brought into operative position relative to the open shed.

Pattern controlled mechanism (or in fact other forms of mechanism for accomplishing this movement) is old and well known in the art and hence is not described herein. The movement from this mechanism to the shuttle carrying frame has heretofore been accomplished by means comprising levers, links or the like. In the construction shown \the motion from the pattern controlled mechanism to the frame is transmitted from the mechanism through an arm'35,only part of which is shown-link 36, lever or rocker .37, and link 38 which is connected to the frame 4 by means of bearing members 39 which are secured to the frame 4. The lever or rocker 37 is secured to a rod or shaft 40 which may be referred to as a rocker shaft. The arms 37 -if there are more than one, in a long machine-may be referred to as lifting arms which are secured to the rod or shaft 40; they are manifestly a part .of the lever or rocker mechanism 37. The rod or shaft 40 extends longitudinally of the machine and is carried on bearings that are on the end or transverse frames of the machine. There may also be provided a cantaliver spring or springs 41 which can be secured either to the lever or rocker 37 or the rocker shaft 40 to which the lever 37 is secured. Thefree end of this spring 42 on the floor. This spring serves as a 41 rests upon a bearing means to counterbalance the weight of the link 38-, the frame 4 and the parts carried by the frame. The arrangement of the levers and links for operatlng the shuttle carrying frame difl'ers somewhat from the constructions heretofore employed and,

therefore, has been clearly shown and described in this application.

' The arm 35 may be considered a part of or as actuated by the pattern controlled mechanism. The link 38 is made adjustable in length by the employment ofa turnbuckle arrangement- 43 or double or oppositely threaded screw construction whereby the height or vertical position ofthe frame 4 relative to the batten-beam 3 can be regulated. The shuttles are carried in the frame 4, as indicated, and can be operated by longitudinally movable racks which are also carried in the frame and which are operated by mechanism well known in the art. A suitable construction whereby shuttles can be moved by means of this rack isshown in U. S. patent to Wagner No. 473,563,

granted April 26th, 1892, for swivel loom.' Such being old, the shuttles, racks and opcrating mechanism whereby the racks may A operate the shuttles are not illustrated in detail on the drawings.-

The improvements herein set forth are not limited to the precise construction and arpasses through said forward rangement shown and described for they may be embodied in Various forms and modifications without departing from the spirit and scope .of the invention.
