PICKEILOHECK FOR LOOMS.
Specification of Letters Patent.
Application filed April 27. 1906. Serial No. 313.988.
Patented Dec. 3, 1907.
To all whom it may concern:
Be-it known that 1, WILLIAM H. AYER, a citizen of the United States, residing at Claremont, in the county of Sullivan and State of New Hampshire, have invented certain new and useful Improvements in Picker-Checks for Looms, of which the following is a specification.
My invention relates to improvements in picker-checks for looms, and refers particularly to an improved mechanism for stopping the flight of the shuttle as it is thrown from side to side in the looms now commonly in-use for weaving textile fabrics.
The object of my invention is the provision of a device of this character which may be readily applied to the shuttle box guide of the ordinary looms now in use, and which will provide a yielding buffer to the picker and will prevent rebounding of the shuttle.
Another object of the invention, is to provide a check which will yield quickly to the thrust of the picker and in the same plane as the picker, and will be provided with a contact surface not easily worn by continued striking thereon.
Further objects of the invention are to provide a picker check which may be adjusted to suit different conditions, consisting of but few and simple parts, and which will be thoroughly practical and ellicient.
With these and other objects in View, my invention consists of a yielding impact band provided with a metal contact surface, a fixed support and an adjustable eccentric support for the band, and a pair of springs connecting the ends of the band.
My invention also consists of a picker check embodying certain other novel features of construction, combination and arrangement of parts substantially as disclosed herein.
Figure 1, is a rear view of a portion of the shuttle box frame of an ordinary loom with my improved shuttle check applied thereto. Fig. 2, is a vertical sectional view thereof on the line 2-2 of Fig. 1. Fig. 3, is a front elevation of my complete check. Fig. 4, is a rear end elevation of the same with a portion broken away toshow the construction thereof, and Fig. 5, is a detached elevation of the base plate of the check.
Referring in detail to the drawings: The numeral 1, designates the shuttle box frame of a loom, to which is attached the shuttle box guide 2, by. means of the bolts 3. The picker 4, picker-stick 5, and picker spindle or guide 6, are all of usual construction, as is also the shuttle box guide 2, provided with the guiding flanges 7. The foundation or base plate to my improved check consists of a substantially triangular-shaped plate 8, which is shouldered as shown in dotted line in Fig. 3, so that it may be attached to the ordinary shuttle box guide by means of a bolt or other suitable fastening 9. At the lower corner or apex of the plate and preferably formed integral therewith, is a lug or post 10, formed with an outer rounded wearing surface in the form of an are as shown. Near the u per portion of the plate, is formed a longitu inal slot 11, and passing through said slot is a bolt 12, provided on its end with a nut 13. Loosely mounted on said bolt and adapted to be fixedly secured thereon by the said nut, is an eccentric roller 14:, and passing over the roller and lug 10, is an impact band 15, preferably of leather. The pair of spiral springs 16, connect the ends of the strap or band, and one of the springs may be anchored midlength, to the plate, by means of a fastening 17', so that the band will not slide out of position. As there is considerable friction on the strap at its point of connection with the supporting posts, an extra layer may be secured on the inner side of the strap as at 18.
On the strap opposite the opening in the flanges, I provide a bearing for the picker to strike against which consists of one or more layers of material 19, secured upon the strap by means of rivets or suitable fastenings 20, and the heads of the rivets thereby provide a durable contact surface and save wear of the strap. 0 c
From the foregoing, it will be seen that I have provided a double roll friction which allows the check strap to go straight back, and as the friction is thereby doubled, the shuttle will be prevented from rebounding after having come in contact with the check. This is a very important feature as it prevents the shuttle rebounding, allowing the shuttle to be bound with less friction on the shuttle binder, and prevents the filling from kinking and thus throwing oil the bobbin.
From this description taken in connection with the drawings, the operation and advantages .of my improved shuttle check Will be readily understood and appreciated.
The position of the impact strap with relation to the flanges of the shuttle box guide may be altened by loosening the nut and changing the position of the eccentric roller, elither by rotating, or moving the bolt in the s 0t.
I claim:
1. In a shuttle check, .the combination with an impact band, shuttle guiding flanges, a fixed second support for the band, of a second support for the band adjustableboth longitudinally of the band and laterally With respect to the guiding flanges.
2. In a shuttle check, the combination With an impact band, of a fixed support therefor having a rounded bearing surface, and an adjustable support capable of longitudinal and transverse adjustment With respect to the plane of the band.
8. The combination With an impact stra having an impact surface of harder material of a pair of spiral springs connecting the ends of the strap, means for anchoring the central portion of one of the springs, a fixed sup ort for the band having a curved bearing sur 'ace,
and an adjustable support capable of longitudinal and transverse adjustment.
4. In a shuttle check, the combination with an impact band, a fixed support for the band, of an adjustable eccentric support for the opposite end of the band. 5. A shuttle check comprising a fixed support, an eccentric support capable of rotary and sliding adjustment, and an impact band arranged on said su ports.
6. A shuttle chec comprising a base plate, a fixed sup-port thereon, an eccentric support mounted on the plate and capable of sliding adjustment, and an impact band passing over said supports.
7. A shuttle check comprising a base plate, a fixed support thereon, a bolt secured in a slotted portion of the plate, an eccentric support adjustably secured on said bolt, and an impact band arranged on said supports.
In testimony whereof I afiix my signature in presence of two Witnesses.
WILLIAM H. AYER,
