SHUTTLE-BOX LOOK FOR LOOIVIS.
SPECIFICATION fOl'ming' part of Letters Patent NO. 783,224, dated February 21, 1905.
Application filed December 31. 1903- Serial No. 187,276.
To all 1077,0711, it may concern:
Be it known that we, WILLIAM H. ROYAL and J AMES PRENDERGAST, citizens of the United States, residing at Frankford, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful 1m provement in Shuttle-Box Looks for Looms, of which the following is a specification.
Our invention relates to a new and useful improvement in shuttle-box locks for looms, and has for its object to provide means for auton'latically locking the shuttle-box against movement while the picker-stick operates to shoot the shuttle along the race in the lathe and to automatically unlock the shuttle-box to allow the same to be moved while the shed is being formed.
lVith these ends in view this invention consits in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim.
In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the acccompanying drawings, forming a part of this specification, in which Figure 1 is a side elevation of my improvement; Fig. 2, a plan View of the same; Fig. 3, an enlarged detail View of the curved arm to which the adjustable studs are secured.
A represents the frame of the loom. B is the rod, which extends upward to the shuttlebox for shifting the same. 0 is the lever pivoted at the point C, which operates the shiftingrod B. Uponthese parts we do not claim any invention, as they are old in looms. Ourinvention consists in securing to the end of the lever C a curved arm or strip D, which is formed concentric with the pivotal point C. This curved arm D has formed through it at intervals slots E, through which extend bolts F, secured to the studs Gr. *Nuts H, threaded upon the other end of the bolts upon the opposite side of the arm D, serve to secure the studs G in place. There are just twice as many studs as there are shuttles in the shuttle-box.
lower arm of the bracket (0 at the point J and extends at right angles with the strip D. The
forward end of this blade in close proximity to the studs G passes through a slotted guide K, secured to the framework. The other end of the blade upon the opposite side of the pivotJ is connected to a rod L, which rod is adapted to be reciprocated at predetermined times by any suitable mechanism connected to the loom. The mechanism shown in the drawings consists of a cam M, operating upon aroller N, secured upon the rod L. This cam is designed to reciprocate the rod in one direction and the spring 0 is adapted to move the blade 1 in the opposite direction. The spring 0 is secured at one end near the end of the upper arm of the bracket CL and at its opposite end to an end of the blade I. As the forward end of the blade I is moved or oscillated it is adapted to move proper shuttle in position for the picker-stick to shoot said shuttle along the race, and this will hold the shuttle-"box steady against any movement while the shuttle is being thrown; but as soon as the shuttle has passed to the other end of the race the cam M will have moved so as to act upon the blade I to move said blade out of engagement with the studs and therefore allow the lever (l to move so as to bring the next proper shuttle in position while the shed is being formed.
The studs Ur, by passing through the slots E in the arm D, may be adjusted either one way or the other, so that the knife-blade 1 in passing between the studs will be sure to bring the proper shuttle in exact alinement with the shuttle-race and hold it in such position while the shuttle is thrown.
Of course we do not wish to be limited to the exact construction here shown, as slight modifications could be made without departing from'the spirit of our invention.
Having thus fully described our invention, what we claim as new and useful is- In combination with a frame having a bellbracket secured thereto, a supporting-rod for a shuttle-box, a plvoted lever for moving said rod, a curved str1p formed on an end of the lever and. having slots, removable studs secured in the slots and projecting therefrom, a blade pivoted intermediate its length to the lower arm of the bell-bracket and extendingat right angles to the curved strip, one end of the blade being adapted to lie normally between certain of the studs, a movable connection at the opposite end of the blade to draw the blade from its normal position, a spring connected at oneend to the upper arm of the bell-bracket and at its opposite end to an end
