ADJUSTABLE PICKJER-VS'TAFF CHECK.
SPECIFICATION formingpart of Letters Patent No. 591,122, dated October 5, 1897. Application filed September 9, 18 96. SerialNo, 605,319. fl lo model.)
To aZZ whom it may concern.-
Be it known that I,- DANIEL H. WRIGHT, a citizen of the United States, residing at Lansin gburg, in the county of Rensselaer and State of New York, have invented a new and useful Adjustable Picker-Staif Check for Looms, of whichthe following is a specification. I This invention relates to picker-staff checks for looms; and it has for its object to provide an adjustable device of this character adapted for use in connection with the picker-staff or lever of the loom to provide simple and efficient means for checking and holding the picker-staff to prevent the tendency of the shuttle to rebound and break the threads, which is of considerable importance inlooms and is a result not always positively secured by the leather checks or straps commonly employed.
With these and other objects in View, which will readily appear as the nature of the invention is better understood, the same con. sists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.
In the drawings, Figure 1 is a perspective view of a portion of a loom equipped with the check attachment constructed in accordance with this invention. Fig. 2 is a bottom plan view of the end portion of the lay-beam carrying the check attachment. Fig. 3 is a transverse sectional view on the line 3 3 of Fig. 2.
Referring to the accompanying drawings, 1 designates a loom of any approved construction, having the usual lay-beam 2, provided at its end with the longitudinally-disposed slot 3, in which plays the upper endportion of the picker-staif or lever 4, which isoperated in the usual manner to provide for driving the shuttle 5 back and forth along-the race of the lay-beam. Ordinarily provision is made for checking the outward movement of the picker-stafi t to prevent rebounding thereof and a consequent rebounding of the shuttle, so that when it (the shuttle) is struck the next time it does not get the full force of the blow, and the result is a broken thread. To provide for this necessary checking of the picker-staff, the present invention contemplates the use of a pair of duplicate flat spring check-plates 5, arranged at one end of the lay-beam 2, below said beam, and secured fast at their inner ends, as at 6, to opposite sides of a depending attaching-block 7, suitably secured to the under side of the laybeam in line with the longitudinally-disposed slot 3 for the picker-staff. The fiat spring check-plates 5 are of sufficient length to permit of the requisite play for the picker-staff and are disposed. oppositely to each other in the same horizontal plane, so as to be arranged, respectively, at opposite sides of the picker-stat? 4:, which is designed to play between said plates and to become frictionally gripped thereby at the outer limit of its movement.
The opposing flat faces of the check-plates 5 are disposed in vertical planes, so as to flatly contact with the opposite sides of the pickerstaff, and the outer movable ends of the plates 5 are normally disposed closer together than the thickness or width of the pickerstaff 4, so that said picker-staff on its outward movement must necessarily force its way in between the'said outer movable ends of the check-plates.
Theouter movable ends of the check-plates 5 are located immediatelybelow the'adjacent outer end of the lay-beam 2, between a pair of parallel pendent beam-ears 8,-projected from the under side of the. lay-beam at the end thereof and located, respectively, at opposite sides of the slot 3, in which the pickerstaif works, The pendent beam-ears 8 are provided on their outer sidesjwith the offstanding socket projections 9, openat their inner ends and having in their outer'closed ends the bolt-openings 10, loosely receiving therein the outer threaded portions 11 of the adjusting-bolts 12, the inner head ends 14 of which are fixedly fitted in the movable end portions of the oppositely located spring check-plates 5, which check-plates, it will be understood, are preferably made of steel spring, so as to have the requisite resiliency. The threaded portions of the adj usting-bolts 12 extend through the bolt-openings 10 of the socket projections 9, and receive thereon the adjusting-nuts 15, working against Washers 16, arranged on the outer ends of the said socket projections 9. Coiled cushion-springs 16 are arranged inside of the socket projections 9 and encircle the bolts 12, with their ends respectively bearing against the outer sides of the plates 5 and the outer closed ends of the socket projections 9. The springs 16 normally hold the movable ends of the plates 5 as close together as required, while at the same time cushioning the outward movement of the said movable ends of the check-plates, so as to retain the said check-plates in firm frictional contact with the opposite sides of the picker-staff 4 when forced therebetween. By manipulating the nuts the normal distance between the movable ends of the plates 5 may be varied to suit the sides of the pickerstaff 4 as the same become worn by use.
In operation the picker-staff 4: plays between the spring-plates 5 and on its outward movement is forced between and frictionally held by the movable ends of the check-plates until the next blow drives it back.
It will be observed that the construction insures the check-plates exerting a gradual tightening pressure on the picker-staif, so as not to materially interfere with its movement, while at the same time preventing any rebound and permitting of the easy release of the staif or lever.
Changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is-
In a picker-staff check for looms, the combination of the lay-beam provided below and at opposite sides of its slot with offstanding socket projections formed with bolt-openings in their outer ends, a fixed attaching-block arranged at the under side of the beam, a pair of duplicate fiat spring check-plates arranged respectively at opposite sides of the picker-staff and fixedly fastened at one end to said attaching-block, the unattached ends of said plates being normally disposed closely together, adjusting bolts arranged in said socket projections and connected at their inner ends with the movable end portions of said plates, nuts engaging the outer portions of the bolts exterior to the socket projections, and springs coiled on the bolts within the socket projections, substantially as set forth.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
DANIEL H. WRIGHT.
