CHARLES A. LAPWORTH, OF HOPEDALE, MASSACHUSETTS.
LOOM-SHUTTLE.
SPEGIFIGATIQN forming part of Letters Patent No. 538,022, dated April 23, 1895. Application filed April 2, 1894:- SerialNo. 506,040- (No model.)
To all whom it may concern.-
Be it known that I, CHARLES A. LAPWoRTH, of Hopedale, county of Worcester, State of -Massachusetts, have invented an Improve:
ment in Loom-Shuttles, of which the .following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
This invention has for its object the production of an improved shuttle of the class employed in narrow ware or gorin g looms, the shuttle to be herein described being adapted to receive a very large cop, off from the end of which the weft may unwind without rotating the cop, the tension device acting to insure the uniform delivery of the weft, notwithstanding variations in the amount of weft on the cop.
The tension device shown may be regulated easily to produce more or less tension on the weft, according to its size, material, or the work to be done, and further, the tension device is of such construction that it does not rub on or injure the thread, and whenever once set may be used without alteration, so long as the same size or number of weft is used.
Figure 1 is a top or plan view of a shuttle embodying my invention, one end of the shuttle being partially broken out to better illustrate the thread tension mechanism.
Fig. 2 is a section in the line as Fig. 1. Fig. 3 is a section in the line no; and Fig. 4. is a detachedview of the bobbin holder.
The body A of the shuttle composed preferably of wood has a large central cavity (1, outside of which is a bow or arch or having a thread delivery eye a out through which to .the fell of the cloth is led the weft w.
The shuttle shown has its rear part cut away or flanged, asbest represented in Fig. 2, to form a guide-way a and leave below it a series of teeth-0., which in practice will be engaged by pinions of raw-hide or otherwise, such as commonly used in connection with shuttle motions'in narrow ware and goring looms to pass the shuttle through the sheds formed in the warps. This class of shuttle ordinarily contains a long rod or spindle extended from one to the other end of the opening of the chamber a, and upon this spindle is mounted a spool having two heads or, it may be, a quill, the weft being led from the side of the spool or quill, so that the spool or quill is obliged to rotate as the weft is delivered from the shuttle. Instead thereof, I have Wound the weft upon a bobbin'b having its base b provided with an annular groove b the base I) of the bobbin being pushed downwardly between two arms or fingers, as c, c, of a U- shaped yoke or device connected with the shuttle, said yoke or device, constituting a bobbin holder, being shown detached in Fig. 4. In this way the bobbin may be pushed into the shuttle and the holder will retain the same in place with the axis of the bobbin substantially horizontal, and, as represented best in Fig. 1, this kind of a bobbin will hold a very large amount of thread, and my improved shuttle may be used for weaving many more yards of webbing or goring than any other shuttle known to me.
The shuttle is provided at that end of the chamber a in which is located the bobbin, with a suitable stand or support d having an upright pin or post (1 on whichis mounted a tension Wheel 6, the periphery of which will preferably be provided with sand, emery, or with sand or emery paper, so as to form a roughened surface to which the weft of the thread will have a tendency to cling.
The tension wheel e isconnected to or forms part of a drum 6', against which bears a brake e hereinshown as a concaved surfaced pad having its shank extended within a coiled spring (2 located in a socket in the shuttle body so that said pad is acted upon by said spring; and the said spring in turn is made adjustable as to its force by or through a suitable regulating device 6 herein represented as a short screw, screwed into the shuttle body, all as shown best in Fig. 3.
The thread from the cop is led through a passage f preferably lined with a vitreous or other tubular eye, and from the outer end of said passage, as represented by dotted lines, through a second passage f, and thence directly about the tension wheel 6 and out through the delivery eye a The weft thread may be wound one or more times about the tension device, so that the strain on the thread will cause the tension wheel to be rotated, and the strain required to effect the rotation of the tension device may be regulated to a nicety by adjusting the screw e, and thus causing the brake e to bear with more or less force upon the drum e.
In the use of my shuttle the thread is not abraded as when it is drawn under a spring, and the tension having been once set, it will remainjust the same until the bobbin has been entirely exhausted, for itwill be remembered that no strain is put upon the thread by unwinding the same from the end of a stationary bobbin.
In practice, the small end of the bobbin 1) will and may stand very close to the inner end of the passage-way), and the longer the bobbin, the more thread, it will be understood, may be wound upon it.
Ido not claim broadly the use of a tension wheel, nor do I claim broadly in ashuttle the use of a stationary non-rotating bobbin, as such abobbin has been used in a fly shuttle, but not to my knowledge in a rack shuttle.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
In a shuttle of the character described,the combination with the shuttle body having the out-going weft outlet and the adjacent return inlet, of the weft tension device arranged 0pposite the return inlet and comprising the r0- tatable wheel eabout which the weft is wound, the support d, d for such wheel, a drum e attached to said wheel and arranged on said support, the friction pad (2 applied to such drum, a spring inserted in a socket in the body and acting to force said pad into constant contact with said drum, and a spring-adjusting device to modify the pressure of the spring, substantially as specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
