JOHN DAVID ULRICH, OF HALDON, NEW JERSEY.

HARNESS SHIFTER AND ADJUSTER FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 577,994, dated March 2, 1897.

Application filed December 9, 1896. Serial No. 614,987. (No model.)

To all whom it may concern.-

Be it known that I, JOHN DAVID ULRICH, a citizen of the United States, residing in Haldon, county of Passaic, and State of New J ersey, have invented certain new and useful Improvements in Harness Shifters and Adjusters 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 a harness and its shafts with means forshifting the harness, that is to say, changing its relative vertical posit-ion on the said shafts for the purpose of introducing at certain intervals new portions of the harness for their looped connections to prevent the said harness at the place above mentioned from being worn through by the continuous friction with the warp-threads and to thus make it more durable, said-means being of simple construction, reliable in operation, and easily attachable to the harness and its shafts without interfering with the working of the same.

The invention consists in the improved harness-shifter and in the combination and arrangement of the Various parts thereof, substantially as will be hereinafter more fully described, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure 1 is a front elevation of a portion of the shafts and the harness carried thereby and provided with my.improvements; Fig. 2, a side elevation of Fig. 1, and Fig. 3 an enlarged sectional View on the line a as of Fig. 1.

In said drawings, a and I) represent the shafts, and c the harness, which latter consists of the looped threads 0 and c connecting substantially midway between the shafts and passing over the outer edges of the latter, all of the usual and well-known construction. At the inner edge of each shaft and near each end thereof are arranged the bearings d d for the shaft or rod e, which latter is provided at one end with a squared portion 6, adapted to be engaged by a key or wrench of any suitable construction. Around said shaft or rod 6 are wound at certain intervals a series of cords f, having their central portions or loops secured to the said shaft, as hereinafter described. One end f of each of said cords f is directly secured to the rod or strip g, while the other end f passes first over the outer edge of its respective shaft and is then also secured to the said rod or strip 9, as clearly shown in the drawings. The said strip is provided with a series of fingers or projections g g by means of which latter it is secured to the band or edge 0 arranged on and connecting the free ends of its respective harness.

The shaft or rod eis provided with an elongated groove, in which is arranged a wire 6 by means of which latter the central portions or loops of the cords f are secured to the said shaft or rod. Said wire extends beyond the bearings d and d and is thus held firmly within the groove.

The shaft or rod 6 is prevented from lateral motion by means of pins h or in any Wellknown manner.

Whenever a certain amount of weaving is accomplished, the shafts or rods 6 on the shafts a and'b are turned by means of the key or wrench. The length of the ends f and f of the cords f are thus changed and the rod or strip 9 raised or lowered, and as the latter is firmly connected with the harness-connecting band or edge 0 above described, the said harness is vertically shifted, that is to say, a new portion of it will form the connecting-loops. By this arrangement the harness is made more durable. The warpthreads Will wear on different portions thereof, as will be manifest.

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

1. The combination with the shafts and the harness carried thereby, of a rod revolubly arranged on each of said shafts, and a series of cords adapted to be operated by said rod and connected with said harness, substantially as and for the purposes described.

2. The combination with the shafts and the harness carried thereby, of a rod revolubly arranged on each of said shafts, and a series of cords coiled around each rod and secured at their free ends to the said harness, substantially as and for the purposes described.

3. The combination with the shafts an d the harness carried thereby, of a rod revolubly arranged on the inner edge of each shaft, and of a series of cords coiled around each rod and secured thereto, one end of each cord being connected with the harness, While its other end passes first over the outer edge of its respective shaft and is then secured to the said harness, substantiallyas and for the purposes described.

4. The combination with the shafts and the harness carried thereby, of a strip secured td the connecting edge or band of said harness, and means for raising and lowering said strip, substantially as and for the purposes described.

5. The combination with the shafts and the harness carried thereby, of a strip secured to the said harness, a rod revolubly arranged on each shaft, and means operated by said rod for raising and lowering said strip, substantially as and for the purposes described.

6. The combination with the shafts and the harness carried thereby, of a strip secured to the said harness and at right angles thereto,

a rod revolubly arranged on each shaft, and a' series of cords coiled around each rod and secured With their free ends to the said strip, substantially as and for the purposes described.

'7. The combination with the shafts and the harness carried thereby, of a strip secured to the said harness and at right angles thereto, a rod revolubly arranged on each shaft, and of a series of cords coiled around each rod and secured thereto, one end of each cord being secured directly to the strip, While its other end passes first over the outer edge of its respective shaft and is then secured to the said strip, substantially as and for the purposes described.

In testimony that I claim the foregoing I have hereunto set my hand this 5th day of December, 1896.

JOHN DAVID ULRICH.
