WILLIAM M. WATTIE, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TO CROMPTON TI-IAYER LOOM COMPANY, OF WORCESTER, MASSACHUSETTS, A FIRM.
LEVER-MOVING MECHANISM FOR LOOMS.
Patented July 23, 1907.
Application filed February 26, 1906. Serial No. 302,928.
To all whom it may concern:
Be it known that I, WILLIAM M. WATTIE, a subject of the King of England, residing in Worcester, county of Worcester, and State of Massachusetts, have invented an Improvement in Lever Moving Mechanism for Looms, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawings representing like parts.
This invention relates to lever moving mechanism of the class commonly used in looms such as represented in United States Patent N 0. 770,167 dated September 13, 1904 and No. 134,992 dated January 21, 1873, said mechanism being employed for moving harness levers, or a shuttle box moving lever. In the patents referred to the connectors have a rather sharp curve or bend near their ends where they are joined to the crank pins of the vibrator gears and the bent parts of the connectors are reduced in depth, which weakens the same.
As vibrator levers have heretofore been made, the sharp curve or bend in the connector has been necessary in order that the connector, when the crank pin of the vibrator gear occupied its position nearest the fulcrum lor the vibrator lever, might embrace the boss at the upper side of the vibrator lever, about which turns the vibrator gear, and the bent part of the connector has been reduced in depth to avoid its striking the teeth of the upper cylinder gear of the two partial cylinder gears. I desire to make the connector stronger, and to so unite the connector and vibrator gear that the axial center of the stud uniting the connector with the vibrator gear will travel in an elliptic rather than in a circular path, thereby obviating any possibility of the connector striking the upper one of the two partial cylinder gears.
Figure 1 in side elevation shows usual parts of a loom including my invention; Fig. 2 is a view of the same parts but in their other extreme position; Fig. 3 is a section in the line rt, Fig. 1, and Fig. 4 shows the eccentric ring detached.
In the drawings, A, A represent in outline partial cylinder gears, B" a vibrator lever provided with a stud B having its fulcrum at B and under the control of a pattern surface a shown by dotted outline, B a vibrator gear, mounted on said pin B, a its stop entering a slot at in the vibrator gear 13", and B a connector engaging said crank pin and which is to be moved by the gear as it is rotated in one or the other direction by one or the other partial cylinder gears. All these parts with the exception of the vibrator lever and connector are substantially as shown in United States Patent N 0. 770,167 referred to.
In accordance with my invention I have provided the vibrator gear with a hole in which I have inserted a ring (1 having an eccentrically placed hole a that receives a hub b formed on or projecting from one side of the connector B intermediate the vibrator gear B and the lever D moved by it as the vibrator gear is turned in one or the other direction two usual partial cylinder gears.
The hub b enters the eccentrically located hole in the eccentric ring, and a stud 0 having at one end a head 0 is extended through the hole in the hub of the connector after the eccentric ring has been applied loosely to the recess made for it in the vibrator gear and 6 5 the end of the stud is then upset, as represented in Fig. 3.
Now viewing Figs. 1 and 2 it will be seen that the stud is set eccentrically to the recess in the vibrator gear that receives the eccentric ring, and as the vibrator gear is turned from the position Fig. 1 into the position Fig. 2 by the upper cylinder gear the center of the pin or stud uniting the connector with the vibrator gear, instead of traveling in a true circle in the dotted line 6 as it Would if the eccentric ring were omitted, the center line of said stud travels in the elliptical path e, shown by dotted lines inside the dotted line path 6, and in this way ample clearance is maintained between the connector and upper cylinder gear in any and all positions and conditions of the vibrator gear controlled by moving the vibrator lever through any usual pattern mechanism In the form in which I have shown my invention, it will be noticed that the part of the connector that overlaps the stud employed to retain the vibrator gear on the hub of the vibrator lever is thicker than in the patents referred to, and is thereby very much stronger.
The ring a has two holes a that in practice are threaded for the reception of two screws 10 that are extended through the end of the connector, thus fixing the ring a to the connector, the ring turning somewhat in the hole made for its reception in the vibrator gear.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:
1. In apparatus of the class described, a vibrator gear having an eccentric ring, and a connector loosely joined to said ring.
2. In apparatus of the class described, a vibrator gear having an eccentric ring, a connector having a boss entering said ring, and a stud to retain said boss in said ring.
3. In apparatus of the class described, a vibrator gear having an eccentric ring loosely mounted therein, a connector and a stud located eccentrically with relation to said ring.
4. In apparatus of the class described, a vibrator lever, 105 a vibrator gear sustained thereby and provided with a hole, upper and lower cylinder gears to engage said vibrator gear and move the same in one and then in an opposite direction, a ring inserted loosely in the hole of the vibrator gear, said ring having an eccentrically placed hole, a connector having a hub entering the hole of said ring, and a stud, said stud as the vibrator gear is rotated traveling in an elliptical path to thus prevent contact of the connector with said vibrator gear.
5. In apparatus of the class described, a Vibrator lever,
a vibrator gear having an opening, a connector having an 10 eccentric ring attached thereto, and a stud in the hole 0 the ring.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses WILLIAM M. WATTIE.
Witnesses CHARLES E. ALDRICH, OSCAR JOHNSON.
