@tutti Stang- CHARLES D. HOUSE, OF LAKE VILLAGE, NEW HAMPSHIRE.
Letters Patent No. 99,674, dated February 8, 1870.
IMPROVEMEN' T IN TWISTING-TUBES PQR SPINNING. M The Schedule referred to in these Letters Patent and making part of the same.
To all whom z't may concern:
Be it known that I, CHARLES D. House, of' Lake Village, in the county of Belknap, and State of New Hampshire, have invented a new and valuable Improvement in 'Iwisting-Tubes; and I do hereby declare that the following is a full, clear, and exact vdescription ofthe construction and operation ofthe same, reference being had to the annexed drawings'making a part of this specification and to the letters and iigures of reference marked thereon. y
Figure 1 of the drawings is a side view of my invention.
Figure 2 is a central vertical section of same.-
Figure 3 is a side view of' same, taken at right angles to theview shown in tig. 1.
Figure 4 is an enlarged sectional view, showing the interior form ofthe conical jaw.
My invention has relation to`spinning-h1achines, and consists, mainly, in the construction and novel arrangemen of devices, whereby al cone-pointed twister is adapted to any grade of yarn, and otherwise greatly improved.
The letter A of the drawings designates the twister,
a hollow tube, of brass or other suitable metal, re-
volved by means of a cord or band connected with the drum of thespimliug-macbine. Sometimes a pulley is arranged 0n the twister, with a grooved edge, in which the cord runs.
B B represent the hollow conical jaws, hinged at each side ofthe tube by means of the rivets a a., or by any other alrangement which will allow them to hang suspended with free motion backward and forward.
That arrangement ispreferable which will, as shown in the drawings, give greater s teadinessl to the points c c, or in which the hinged points are at the greatest distance from each other.
Ears d d are formed at the upper part of each jaw,`
projecting up from the middle between the hinged points, aud-slightly heilt outward at the tips, to receive the conical base of the cam-weight D.
The adjacent surfaces of the points c c of the jaws are plain for about an eighth of an inch from the extremities, so that the roving is not nipped, as heretofore has been the case, by the thin biting edge in use.
There are several ways of adjusting the cam-weight D so that it will operate the jaws. 4Sometimes I employ two weights, arranged to slide up and down by means of' slots formed in the tube above the ears d d. Sometimes the weights are fixed upon the projections or ears d d themselves; but, generally, I prefer the annular cam-Weight D, as shown, encircling and sliding freely ou the twisting-tube.
The cam-weight D has a conical base, which descends between the ears d d of the jaws, and presses them outward, thus bringing together the points c c with a degree of force depending on the weight of the cam D. Thus, by the use of cams of different'weights, the same twisting-tube andv delivering-points may be used for any number of yarn, whether coarse or fine, loose or closely twisted.
The cam-weight shown in the drawing is adapted for No. 4% yarn-a medium grade. V
In the use of springs or other elastic devices for keeping the conical points together, a passing knot will have a tendency. to throw the points suddenly apart, when they will as quickly'eome together, and, if' theedges be thin, or not exactly opposite each other, as is usually the case, the roving will be cut.
I do not claim the'use of elastic force for the purpose of keeping my improved conical points together;
but
What I claim as my invention, and desire to secure by Letters Patent, is v 1. The adjustable conical delivery-jaws B B, hinged to the twisting-tube of a spinning-machine, and operated by the variable sliding cam or weight D, as shown and described. l
2. The hinged jaws B B, having upward projections 'or ears d d, and broad plane inner surfaces to the delivery-points c c, as shown and described.
' In testimony that I claim the above, I have hereunto'subscribed my naine in the presence of two witnesses.
CHARLES D. HOUSE.
W'itnesses J oHN ALDRICH, Josu L. FLANDERS.
