Specification of Letters Patent.
EFatented Nov. 24, 1914.
Application filed. February 8, 1913. Serial No. 747,078.
To all whom it may concern:
Be it known that I, DURELL O. PEASE, a citizen of the United States of America, and resident of Hampden, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Thread-Boards for Spinning-Machines, of which the following is a full, clear, and exact description.
The object is to provide an improved thread board, or a series of guides for spinning frames which is more particularly adapted to those frames designed and built for the spinning of what is known as condensed rovings or rovings made by the woolen process.
The form of thread guide most commonly employed is defective for this class of spinning, for what is known as the pig-tail or yarn guide stands out from the backboard and leaves an open space between the adjacent guides.
The cause of the above named defect lies in the fact that when a broken end occurs in the spinning of this kind of roving, the end extending from the bite of the delivery roller tends to come straight down and is almost certain to fall or get caught in some one of the immediately adjacent ends to cause snarls that will break many more ends before the attendant can get them pieced up; but by providing a thread board as here shown and described, no broken end can get past the location of the thread board to cause the aforenamed trouble.
And in the present device means are provided with which the yarn or thread may be engaged and by which it will be retained in the operation of piecing, it being understood that in this class of spinning the ends on the yarn have to be untwisted and made soft in order to be pieced or spliced, and so, when a piecing is to be performed, the yarn end below the thread board and toward the spindle is upwardly drawn to a position above the thread board and caused to have an engagement with the latter while the portion coming from the delivery rolls is adj oined therewith.
A further improvement consists in the provision of parts or sections of the thread board which are operative to guide and retain the yarn over the center of the spindle,the same being adjustable so as to be properly positioned even although the rail in a comparatively long spinning machine may be more or less undulating or untrue as regards the line of its forward edge, and such adjustable parts or sections moreover are removable so as to be replaced, after having become badly worn, by new and perfect ones. i
The invention is described in conjunction with the accompanying drawings and is set forth in the claims.
In the drawings :Figure l is a plan view of a comparatively short portion of a thread board constructed in accordance with the present improvements. Fig. 2 is a sectional elevation of a sufficient portion of a spinning frame to show the position of the thread board with relation to the delivery rolls and spindles. Fig. 3 is a cross sectional view on line 33, Fig. 1.
In the drawings, A represents the main longitudinally ranging supporting rail of which the thinner and narrower supplemental rail section A is the same as an integral I part; and to the supporting rail a plurality of blocks B are connected by hinges b.
Each block B is made with a shallow forwardly opening channel (Z within its top; and each so channeled block receives therein the shank portion 7 of an L-shaped steel plate, the flange portion 9 of such plate being downwardly extended forward of the The forward depending flange like mem- I ber of each of the confined plates is to be adjusted in position coincident with the axis of the spindle m which has the usual location therebelow, and to which spindle the thread or yarn is brought from the delivery rolls to 'w, guided through the thread board.
Each clamping plate D secured above the L-shaped plates and extended considerably forwardly beyond them, is provided with a recess 2' which extends from its forward edge rearwardly more or less beyond the location of the depending flange like portion 9 of the other plate.
Each of these recesses is widened beween its forward and rear ends forming a pair of shoulders j y as shown, and such recesses forwardly from the widened shoulder forming places are forwardly divergent to permit of the quick and easy entrance of the yarn to its place of guidance or to its engagement with either one of the shoulders at the time of piecing up.
The support blocks in each of which one, or more than one, set of the L-shaped, and clamping, plates are provided by being hi it to the main support rail may be swung back for dolling as usual in this general class of appliances; and by making and combining the parts as described, the l.- shaped plates are individually adjustable so as to be brought with their flanges all in alinement even although the supporting rail may be considerably warped or out of true.
'lhe upper plates, the transverse edges of which are contiguous, close the spaces be tween the guides and form a guard or barrier below which a broken yarn cannot pass to become entangled with and cause breakage of other running yards.
When a yarn or thread becomes severed and it is required to piece the same, the portion or broken end below the thread board and toward the spindle is seized, carried into the recess e' in the upper plate which has a shelf like extension forward of its supporting member, and by a sidewise movement is brought to engagement with a shoulder j at either side of the recess. This stays the lower yarn end, it being retained in its shoulder engaged position with one hand while a splice or piecing with the other end coming from the delivery roll is being accomplished in the usual manner.
Although the L-shaped plate are made of hardened steel, they will under protracted use become grooved at their fronts so as to be impaired in elliciency; and their re placement by new ones may be readily effected by simply loosening the bolts which confine the upper clamping plate and after the engagement and adjustment of a new l..-shaped plate in the shallow channel therefor, the bolts will be again tightened.
The making of the mouth portions of the recesses 2' forwardly divergent and having the corners of the plate at the opposite margins of the recessed mouths rounded conduces to the facility of introduction of the yarn to its running line of guidance and prevents any liability of the same becoming caught or broken in any stage of a piecing up operation.
I claim 1. In a thread board for spinning machines, the combination with a supporting member having a forwardly opening channel within its top, of an l -shaped plate having the shank portion thereof disposed in said channel and having the flange like portion thereof downwardly extended forward of the edge of the supporting member, and another plate detachably secured on the to of the supporting member having a clamp ing confinement on said plate, and provided with a recess extending from its forward edge rearwardly beyond the location of the forward flange like portion of the L-shaped plate.
2. In a thread board for a spinning mas chine, the combination with a main supporting rail, of a pliilrality of blocks hinge connected on the front of the rail and each having a forwardly opening channel within its top, a series of L-shaped plates each having the shank portion thereof disposed in said channel and having the flange like portion thereof downwardly extended forward of the edge of the supporting block and a further series of plates detachably secured on he tops of said bl0clrs,having clamping confinement on said plates and each provided with a recess extending from its forward edge rearwardly beyond the location of the forward flange lilre portion of the L- shaped plate clamped thereby, such recess being widened to form a shoulder at one side thereof between its forward and rear end.
Signed by me in presence of two subscribing witnesses.
