UNITED STATES PATENT orrron OSCAR L. OWEN, OF WHITINSVILLE, MASSACHUSETTS, ASSIGNOR TO THE WHITIN MACHINE WORKS, OF WHITINSVILLE, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.

THREAD-BOARD FOR SPINNING-MACHINES.

PatentedSept. 29, 1908.

To all whom it may concern:

Be it known that I, OSCAR L. OWEN, a citizen of the United States, residing in VVhitinsville, county of Worcester, State of Massachusetts, have invented certain new and useful Improvements in Thread-Boards for Spinning-Machines, of which the following is a full, true, and concise specification.

My invention relates to means for supporting and controlling the thread-guiding mechanism of spinning machines, and more particularly of certain forms of spinning machines wherein a receptacle is provided beneath the delivery rolls for receiving and holding the broken ends of the yarn. In such machines the finger-heads have generally been hinged directly to the forward marginal support of the said receptacle and have heretofore been without provision whereby they may be simultaneously'shifted to dofling position. The present invention aims to provide a mounting for the finger-heads of such machines which. is compactly associated with the yarn-receiving receptacle and other existing parts so as not to require an extension of the lateral dimension of the machine and which is adapted to permit the above mentioned simultaneous operation of the finger- The invention, however, is also capable of advantageous employment with other forms of spinning machines wherein compactness of the mounting of the fingerheads is necessary or desired.

Referring to the accompanying one sheet of drawing which forms a part of this application, Figure 1 is a top plan view of a sec tion of so much of a spinning machine as is necessary to illustrate the structure and use of my invention; Fig. 2 is a front elevation thereof, the delivery rolls and spindles being removed; and Fig. 3 is a general vertical section of Figs. 1 and 2.

The spinning machine illustrated in the above figures comprises the usual delivery rolls 1 mounted in the usual manner on the roller-beam 2 and adapted to deliver the thread or yarn to the series of spindles 3., all of which parts are operated in the usual and well understood manner.

Between the rolls and spindles each thread is guided by the usual thread-guide 4 and in case of breakage of any such threads, the broken end falls into a yarn-receiving space or receptacle 5 which is located directly beneath the delivery rolls and serves to hold the accumulations of thread following the break, free from entanglement with adjacent unruptured threads until the operator finds time to repair the break. The said receptacle may conveniently consist of an openended trough-like receptacle appropriately held by its rear margin to the under side of the roller-beam and by its front margin to a horizontal beam 6, which beam is off-set forwardly from the vertical plane of the delivery rollers, being s'u ported and spaced from the roller-beam 2 y means of a series of studs 7. The beam 6 supports the threadguiding mechanism of the machine and is referably, and according to this invention, formed as a flat bar disposed with its narrowest edge uppermost, in which position it occupies the least s ace laterally and is stiffest against vertica stresses. The threadboard rail 8, consisting of a flat bar preferably of'about the same dimensions as the supporting beam 6, is hinged to the said beam so that when in its upright or working position it occupies the same vertical plane as said beam 6, with its front face substantially flushwith the front face of said beam, and rests upon or over the up er edge of said beam. The hinges 9 are app ied to the rear faces of the two members so that the rail may be turned rearwardly or downwardly into or toward the yarn-receiving space above mentioned. The thread-board rail supports the series of finger-heads 10 projecting laterally and horizontally from the front face thereof so as to hold their thread-guides 4 in alinement with the axes of the spindles and the said fmger-heads are each hinged to the rail 8 by a hinge 11 so as to be capable of being individually lifted or turned back with'respect to said rail. The thread-board rail is coextensive with the beam 6 throughout its length and at oneend or at any desired location is provided with a hand-grip 12 by means of which it may be turned on its hinges so as to shift the finger-heads simultaneously into their rearward position, which will rovide access to the spindles for dofling. T e hand gri depends somewhat below the hinges 9 an on the forward side of the beam 6, so as purpose if desired. The relation of the finger-heads to their supporting members is such that by virtue of the arrangement of the hinges 9 and 11 it is possible to turn the thread-board rail into and out of its doifing position without swinging the fingenheads on their hinges, which permits all of the finger-heads of a series to be simultaneously returned to working position by the mere operation of the hand-grip 12.

Having described my invention, what I claim and desire to secure by United States Letters Patent, is

1. I11 a spinning frame, a horizontal beam, a thread board rail normally disposed above and in the same vertical plane therewith and provided with a hinge whereby it may be turned downwardly toward the space behind said beam, in combination with a series of finger-heads pivotally mounted on said rail to project laterally from the front vertical face thereof. I

2. In a spinning frame, a horizontal beam, a thread board rail normally disposed above and in the same vertical plane therewith and provided with hinge connections to said beam whereby it may be turned downwardly and rearwardly thereon, in combination with a series of finger-heads pivotally supported along said rail and means for maintaining said rail in its Working position above the beam.

3. In a spinning machine, a horizontal beam forming a support for the thread guiding mechanism and a rail disposed above said beam with its forward face substantially flush with the forward face of said beam, in combination with a hinge for said rail Whereby it may be turned rearwardly from such position and a series of finger-heads hinged to and normally projecting laterally from the face of said rail.

4. Ina spinning machine, means for supporting the thread guides comprising a flat beam supported with its narrow edge uppermost, in combination with a flat rail normally disposed in the same vertical plane with said beam and hinged thereto to turn rearwardly,

and a plurality of finger-heads hinged to said rail and projecting laterally therefrom.

5. In a spinning machine, the combination of a fixed horizontal beam supported at a distance from the roller beam aml providing a yarn-receiving space therebetween, a thread board rail having its working position above said beam and hinged to swing rearwardly toward said space and a series of linger-heads pivotally carried by said thread board rail.

6. In a spinning machine, a fixed horizon tal supporting beam spaced from the roller beam and provided with a hinged threadboard rail adapted to rest, in its working position, upon the upper surface of the said supporting beam and a plurality of linger-heads hinged to said rail to be supported thereby in horizontal position.

7. In a spinning machine, a horizoi'ital beam forming a support for the thread-guiding mechanism and separated from the vertical plane of the delivery rolls by a \ui.r n-receiving space, in combination with. a threadboard rail hinged to said beam and having its working position above and in the vertical plane of said beam, and a plurality of lingerheads hinged to said rail and means for turning said rail on its hinge.

8. In a spinning machine, a llat horizontal beam supported with its narrow ed go uppermost and a fiat thread board rail normally disposed with its narrow edge resting on the edge of said beam and provided with a hinge whereby said rail may be turned rearwardly and downwardly from such position, in combination with a series of finger-heads pivotally supported on said. rail and normally in horizontal position and means for maintaining said rail in vertical position.

In testimony whereof, I have sigi'ied my name to the specification in the presence of two subscribing Witnesses.
