SHUTTLE-CHECK FOR LOOMS.
SPECIFICATION formimg part Of Letters Patent NO. 699,445, dated May 6, 1902. Application filed September 7, 1900. Serial No. 29,289. (No model.)
To all whom it may concern.-
Be it known that 1, JOHN C. BRYAN, acitizen of the United States, residing at Augusta, in the county of Richmond and State of Georgia, have invented a new and useful Shuttle- Oheck for Looms, of which the following isa specification.
This invention relates to shuttle-checks for looms; and the object of the same is to provide simple and effective means forpositively holding a shuttle at opposite sides of a loom, so that it will be held in true alinement when successively shot and released at the proper time by automatically-operating mechanism conjnnctively coaoting with filling mechanism.
The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.
The figure of the drawing shows aside elevation of a shuttle-box and picker-stick with the features of theinvention applied thereto.
The shuttle-box 5 in the present instance comprises upwardly projecting frames 9, which have horizontal members extending over opposite side portions of the race a suitable distance, and therein is mounted a pivot rod or bolt 11, which passes through upstanding ears or lugs 12 of a presser-plate 13, having at its inner end an upturned lip 14, with an adjacent under smooth face 15 for the easy passage of the shuttle 16 thereunder. On opposite sides of the outer extremity of the plate 13 are depending guard-flanges 17, and the outerterminal 18 is also slightly flared in an upward direction, and the under face of the plate, below the fulcrum thereof, is slightly concaved, as at 19, so as to avoid bearing on the intermediate portion of the shuttle. The guard-flanges 17 straighten the shuttle relatively to the remaining portion of the shuttlebox in the event that it shall have become slightly deflected from its path on the lay It is intended that there be just room enough beneath the presser-plate at its inner end for the shuttle to pass and which will be materially controlled by tapering the opposite ends of the shuttle, as shown, and in view of the force and speed that the shuttle attains by its movement through the shed it will be necessary at the end of the fly to check said movement in order to bring the shuttle into propel-position in the box. For this purpose the inner end of the presser-plate 13 is normally disposed at an upward angle to the race 6 and is so held by a tension-rod 20, having an upper angular end and fastened in lugs 21 at the inner extremity of the said plate and extending downwardly through an car 22 on the front lower side of the lay and carried by a sleeve 23 on a rock-shaft or protection-rod 2.4, extending in a transverse direction and connected to the lay, as shown. The tension-tod is movable in the car 22 and may be adjusted to ease the movement of the plate 13 or to render the same less sensitive, the means employed for such adjustment, as shown, consisting of oppositely-positioned nuts 25 and 26,aspring 27 surrounding the rod between the nut 26 and the under face of the car 22 to always return the said rod to a predetermined normal position after the outer end of the plate 13 has been depressed by the passage of the shuttle there under.
As previouslyindicated,theinner extremity of the plate 13 is normally positioned at an upward incline toward the race and the outer end depressed, and asthe shuttle 16 moves under the plate said inner extremityis depressed, and simultaneously the outer extremity is elevated by the shuttle nose or end striking the outer depressed end, as will be understood from the pivotal mounting of the said plate. This causes the outer end of the plate 13 to bear on the shuttle with more than normal force, whereby the shuttle will be slowed down and stopped at approximatelyits proper position in the shuttle-box. To assist in guiding the shuttle into the box, a vertical flange 28 is secured to or forms a part of the said box and extends inwardly over the race a distance about equal to the inward projection of the plate 13. When the shuttle is in the box, as shown, its outer nose will bear against the picker. The bind of the outer extremity of the plate on the outer end of the shuttle is maintained by the spring 27 on the rod 20, and when the shuttle is impelled by the pickerstick 4 it is started against the resistance of said spring, which permits the rod 20 to have sufficient vertical play to allow the shuttle to clear itself without binding.
After the shuttle has passed out of the box the plate resumes its normal position and is in readiness to again check the shuttle.
The rock-shaft 24 is the usual protectionrod in looms, and advantage is taken of its motion and location to effect the desired operation of the presser-plate 13. The mechanism for operating the said shaft 24 is similar to that disclosed in the patentgranted to O. F. Pei-ham, dated June 23, 1896, No. 562,653. It is necessary to quickly clear the shuttle for propulsion of the same by means of the picker-stick through the shed without binding friction or material obstruction of the plate 13, and at the proper moment the said rock-shaft or protection-rod 24 moves in a direction to lower the tension-rod 20 through the ear 22, hearing against the spring 27 and nut 26.
Having thus described the invention, what is claimed as new is- 1. In ashuttle-check, the combination With a shuttle-box, of a top presser-plate pivotally hung at a point intermediate of its ends, the outer extremity of the plate having opposite depending flanges and normally held in depressed position for contact with the shuttle, the shuttle raising the outer extremity of the plate when assuming an operative position in relation to the pick mechanism for the shut tie, and means connected to the inner extremity of the plate for restoring the same to normal position after the shuttle has passed out of the box.
2. In ashuttle-check, the combination with a shuttle-box, of a top presser-plate pivotally mounted above the box and having the fulcrum therefor located at a point intermediate of the ends thereof, the outer end of the plate being normally depressed and the inner end elevated to respectively contact with and clear the shuttle, the shuttle raising the outer end of the plate in passing under the latter, and means for cushioning and restoring the plate to normal positionconsisting of a tension-rod under spring control and a rocking element connected to said rod.
3. Mechanism of the character set forth, including a shuttle-box, and a top presserplate movably mounted therein having 0pposite depending flanges.
4. In an attachment of the character set forth, the combination with a shuttle-box, of a top oscillatable presser plate pivotally mounted above the box and adapted to have its outer extremity bear upon the shuttle, a rod attached to the inner extremity of the plate and having adjusting-nuts on the lower end thereof, a rocking element having an ear through which the lower end of the rod extends, the upper nut having contact with the upper side of the ear, and a spring on the lower end of the rod between the said ear and the lower nut.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
JOHN C. BRYAN.
