.SH EDDlNG MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 550,126, dated November 19, 1895.

Application filed June 13, 1895. Serial No. 552,623. (No model.)

To all whom it may concern:

Be it known that I, ALFRED GARTNER, a citizen of the United States, residing in Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Shedding Mechanism 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.

This invention relates to that class of shedding mechanism for looms called the dob bies, and is an improvement on United States Patents Nos. 217,589 and 336,683.

The invention consists in the peculiar construction of the rods supporting the jacks, in the pivotal connection of said rods with the liftingdevers, and in the combination and arrangements of the various parts, substantially as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings, Figure 1 is a sectional side elevation of a dobby provided with my improvements; Fig. 2, a detail view of one of the jack-supporting rods.

In said drawings, a represents the frame; I), the harness-lever; c, the connector pivotally secured to said lever b; d and e, the upper and lower hooked jacks, respectively, pivotally secured to the said connector, and f and g the lifters, all said parts of the usual construction.

I Pivoted, as at k, is the lifting-lever z, acted upon by the pattern surface or chain min the usual manner. To the inner end of said lever 11 is pivotally secured the upwardly-extending rod h, which for that purpose has its lower end bent horizontally, as at 71 Fig.

2, and rests with said portion h in a horizontally-arranged hole of lever i. The upper end of the rod h is also bent horizontally, as at h, and bears with said horizontal portion under the upper jack (1, while the lower jack e rests upon the loop h projecting horizontally from and integral with the rod h.

From the foregoing it can be seen that by hawlng the rod h pivotally connected with the lifting-lever 2' an absolutely-certain movement of the rod h, and thus of the upper and lower jacks, is obtained without duplicating the lifting-levers, as in United States Patent No. 243,361, thereby avoiding the frequent sticking of the rods and thus their disengaging from the respective lifting-levers.

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

The lifting lever provided at or near its inner end with a horizontally arranged hole or opening, the pattern surface to operate the said lever, combined With the upper and lower hooked jacks, the connector, the lifters to engage and move the jacks, and with the rod h, an intermediate loop formed in and by said rod, projecting horizontally therefrom and adapted to directly support the lower jack, a bent portion on the upper end of said rod to support the upper jack, and a bent portion at the lower end of the rod adapted to rest in the horizontally arranged hole in the inner end of the lifting lever, to thus prevent the disengagement from the same, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 10th day of June, 1895.

ALFRED GARTNER. Witnesses:

ARTHUR H. THOMSON, WM. D. BELL.
