Todll .t1/hom z't may concern: Be vit known that I, Hormon WYMAN, a citizen ofthe United States, residing at Worcester, in the county of ent, No. 306,726, and more particularly relates-tothe; magazine of tlietype shown in my said patent, which has a plurality of compartments o r stacks for the lling carriers or bobbins, one of which is automatically supplied to the running shuttle on the .erhaustion,l or substantial exhaustion of filling therein.

I nmy improvements, I preferably provide, `instead of a rocking or pivotally supported magazine for the filling carriers, v a magazine having a sliding or reciprocating movement, preferably in a Ahorizontal plane, which movement is preferably controlled by the movement of the pattern indicating mechanism, not shown,

' through interrnediate connections, inthe usual and usual and welll known construction, and operated in any usual and. wellfknown way.-

f I have shown in the drawing a detached portion of a 'loom frame', and some other parts oi aloom, with my- 'improvements in magazine combined therewith, suffivwell known manner, and as fully shown and:described In my improved magazine, I preferably provide a plurality Iof guides or channels. forming stacks orfcom partments for *the filling carriers onbobbins, which drop down in said compartments by gravity, and each compartment has its lower discharging end preferably offset or inclined,iand Wmvided with a spring, or' other means for yieldingly holding. the lowest lling carrier br bobbin in @ich compartment, in position to .be trans? ferred ytherefrom into the running' shuttle.' Each com- `partment of. the magazine isprovided'with a transvferrer, movable. with the magazine, and with the lower end oi the transierrer extending over and in alinement with the bobbinat the lower'end of the compartment.

l Eachitransferrer is provided withV adevice which, when magazine-is moved into a position for the discharge of the desired bobbin, will bein position to be engaged by a transferreroperatingv arm, which may be of any cient to enable thoseskilled in the art to understand the construction and operation ofthe same.

In the accompanying drawing, lis a portion of a loom side or frame, 2 the loom arch, 3 the lbreast beam, 4 the lay, 5 the lay'T sword, G the picker sticlr, and 7 the sli-little.

I will nowidescribe my improvements in magazine.

8 is a stand bolted to the loom frame and arch. The stand 8 has ,in this instance projections 8l thereon, in which are secured two horizontally extending parallel rods 9 and l0, see Fig. 2L

The magazine consists in this instance oi 'an inner vertically extending plate 11, and an outer vertically extending plate 1l said plates are connected at their point indicated by line 3, 3, Fig. 1,'looking in the diupper ends by two

transverse bars

12, and 12/, and near their lower ends by a transverse bar 12, see Fig. 2. The' plate ll`has in this instance a series of vertically extending guides or channels l1 thereon, in this instance four in' number, which' act as guides for the inner ends or heads of the bobbins 13,- see Fig. 3. The'outer .plate 11 ,has also in this instance a series oi vertically extending guides or channels ll, in this instance four in number, which acts as guides for the outer ends of .the bobbins, see Fig. 3. The channels 11 and 11' in this instance form compartments or stacks for the bob bins' 13, which are placed in position through the upper open ends ofthe channels 11 and 11', and drop down therein by gravity.

The lower end oi each channel 11l and 11/ is prefen ably madeinclined or offset, as shown in Fig. 2, and forms the discharging end, and is preferably provided "with a light leaf spring, as 14, or some other suitable de vice, to engage the head ofthe bobbin, and also the opposite end of the bobbin, and hold the same yieldingly in position at the lower discharging end of the compartment, ready to be acted on by the transferrer.

The magazine is lsupported-to have a slidingor re* ciprocating movement, preferably in ,a horizontal plane, inthis instance by inwardly extending lugs or ears thereon; one oi which, as 15, is shown in Fig. 3.

'The lugs or ears l5 arelloosely mounted on the rods 9 and 10 toslidethereon.

A transferrer'- device is provided for eachfcompartment, and consists in this instance 'of a vertically extending wire or rod 16, having a vertical movementin guides or bearings 17 and 17 on the inner side of the inner plate 11 ofthe magazine. A coilexpansion spring 18 encircles each rod 16, and bears at its lower end Aagainst the lower guide or bearing 17, and at its upper end'against an arm 1 6 fast on the rod 16, and extending rearwardly therefrom through a vertically extending elongated slot or opening 1l in the rear plate 11 of the magazine, see Figf. The lower end of the rod 16 has fast thereon in this instance, the 'nub 19 of a transierrer' movpment of the rod 16. The transferrer 19 extends over and is in alinement with the lowest bobbin 13 in acompaptnient.

20 with an angie lever 2], pivoted on a stud 211". The angle lever I2l, through connector 22 to mechanism not shown, may have a movement communicated thereto, A,

according to the movement of the pattern indicating mechanism, not shown, at the opposite end of the loom,

in th e manner iuily shown and described in said Patent,

N o. 806,726, to move the magazine having the compartments or stacks for the hobbins therein, to such a p osition that the lower bobbin `in any one ot' the compart-fments, as desired, will `bey brought ove'r'the running shuttle 7as shown in Fig'. 2, preparatory to being transferred from the compartment, through the operationof the transferrer 19 and rod 16, into the shuttle. Each rod 1G and the transferrer 19 thereon, is operated in lthis instance, when any one of the lcompartments of the magazine is in the desired position for the discharge of -a hohbin therefrom, by the transferrer operating arm or lever 23, having the engaging end 23 thereon, sec F ig. 3, which in this instance is 'adapted to extend over and in a posQon to engage the projecting arm 1li on a. transcrrer rod i6, of the compartment which has its discharging end in alinem'ent with the shuttle 7, on the forward stroke of the lay, as shown inlig. 2. The transferrcr operating arm 23 has ,fa huil 23, in this instancevloosely mounted on a stud 27,4', secured in the stand 8. A spring 25 acts to return said arm 23 to its normal raised position, alter it has been operated to transfer filling.

Extending dowri from' the hub 23 of the 'transferrer operating arm 23, is an arm 26, having in this instance the bent end 26. Ona pin`27on the lower end 26 of the arm 26, is 'pivotally' mounted al linger 28, with a downward projection 28- thereon ,extending in the path of, and adapted to be engaged and mov'ed hy an' arm 29, the hub 29 of which is pivotaliy mounted on a stud 30,

' and hasan arm 29 thereon connected with one end of a connector 31 to indicating mechanislmfnot shown,- A

spiing 32 acts, in this instance, to hold the finger 28 in' its raised position, shown in Fig. 2. On the front ofthe lay 4 is a dagger 33, adaptcdto engage theend of the y finger 28, when said finger is lowered and is in alinement`with said dagger, to'operate the finger 28 and the transierrer mechanism, in the usual Way.

The operation of my improvements will be readily,

understood ley .thoseskiiied in the art. The magazine having corripartments or stacks for the bobbins or filling carriers, is moved back and forthon the rods 9, and 10,A
