SHEDDING MECHANISM FOR LooMs.

SPECIFICATION forming part of Letters Patent No. 550,459, dated November 26, 1895.

Application filed .Tune 20, 1'895. Serial No). 553 ,405. (No model.)

To @ZZ whom t may concern:

Be it known that I, ADAM SCHEID, a citizen i of the United States, residing in Harrison,

Hudson county, and State of New Jersey, have invented certain new and useful Improvements in Shedding lWIechanism for Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to provide adjustable means for supporting and operating the hooked jacks in a dobby of ordinary construction.

The invention consists in the improved j ack-operating mechanism,its adjustable supporting-arms, and in the various parts thereof, substantially as will be hereinafter more fully described, and inally embodied in the clauses of the claim.

Figure 1 is a side elevation of a dobby provided with my improvements, and Fig. 2 an enlarged detail view of one of the hooked jacks operating-levers and its adjustable supporting-arms.

The frame a, the harness-lever b, the connector c, the hooked jacks d and c, and the lifters f and g are of the well-known usual construction. The lifting-lever h, pivoted as at c' to the frame a and operated by the pattern-surface m in the usual manner, is provided at or near its inner end with an upwardly-extending rod h', the horizontally-arranged pin Ihm of arm h resting in the vertical slot 71u11 of lever h. Near the upper end of Vsaid rod h is arranged an elongated vertical slot h4, in which is adjustably secured, by means of bolt and nut h5, or in any other desired manner, the arm h2, adapted to bear on the under side of the upper hooked jack d. In the lower portion ofv the rod h' is also arranged an elongated vertical slot h6, in which is adjustably secured, by means of bolt and nut k7, the arm h3, which latter bears against the under side of the lower hooked jack e.

It is a well-established fact that the ordinary supporting means for the hooked jack, during the frequent usage of the dobby, get worn off very rapidly and must be substituted by new ones from time to time to insure a perfect operation of the machine. This I have avoided by arranging the arms h2 and h3, supporting the hooked jacks, adjustable on the carrying or supporting rod h'. As soon as the top portion of the said arms is worn o the nuts of the bolts h5 and hFl are loosened and the arms slid upward and turned outward in their respective slots to the height and position required, and the nuts are then again tightened up.

I do not intend to limit myself to the precise construction shown and described, as various other means can be employed to answer for the above purpose without changing the scope of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a dobby, the combination with the upper and lower hooked jacks and with the pattern surface, of a lifting lever acted upon by said pattern surface, a vertically arranged rod supported by said lifting lever and provided with an upper and lower elongated vertical slot, and an arm adjustably arranged in each of said slots and adapted to support the upper and lower hooked jacks respectively, substantially as and for the purposes described.

2. In a dobby, the combination with the harness lever, the connector attached thereto, the upper and lower hooked jacks pivotally secured to the said connector, the lifters to engage and move the jacks, the lifting lever, a vertically arranged rod supported by said lifting lever and provided with an upper and lower elongated vertical slot, means adjustably arranged in said slots and adapted to support the saidhooked jacks, and means to operate the lifting levers, all said parts substantially as and for the purposes described.

In testimony that I claim the foregoing I have hereunto set my hand this 16th day of May, 1895. I v ADAM SCHEID.
