TO ALL REESONS TO WHOM THESE PRESENTS MAY COME:
Be it known that I, Gnonos Dnnrsn, of Hope'dale, of the county of Worcester, and State of Massachusetts, havc made a new and useful invention, having reference to the Let-Off" Mechanism of n Loom for weaving cloth; and I do hereby declare thc'ssme to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure 1 is an elevation, and
Figure 2 an end view of a loom-frame, its sley and yarn-beam, as provided with my invention; the first of such figures being made to exhibit the yarn-beam side of the frame.
On the sixth of January, A. D. 18-14, a patent was granted to William Brayton, of Warren, of the State of Rhode Island, for an improved let-elf motion for regulating the delivery of the yarn in a weavingdoom.
, My invention is similarin some-respects to that of Brayton, although difi'ering therefrom in important particulars, and such particulars Ihave hereinafter described. 7 I V In carrying out my invention, I connect the spring of the fri ctiomstrap with the lay by means of a rod, or its equivalent, pivoted to the lay. Y
Without the said connection, or its equivalent, the yarn will be delivered by the beat of the slcy and the strain of the warps at the period when the weft is being beaten in.
My combination or invention prevents the delivery of the yarn at the beat, as under such circumstances the friction on the wheel of the friction-strap will be increascdrather than diminished. The yarn or warp will be delivered only when the strain on it is sufiicient to turn the yarn-beam without regard to the beating in of the weft. i f In the drawings, Adenotes the loom-framo, B the lay, G the yarn-roller or beam, and D the whip-roller.
The said whip-roller has its journals supported in hearings in twoar ns, is a, projecting from a shaft, 6, which extends acrossthe loom, and is sustained in hearings in the frame A. i A A. long arm, 0, projecting down from one end of, the shaft, bears against a spring, (1, which, at or near one end, is fixed to the. girt, e, of the frame A, and at the other to one end of a friction-strap,f, which'gpes partiallyebout the-periphery of n wheehg, and is fastened to a stud, k, extended from the loom-frame.
The said' wheel'g is fixed on a shhft, 2', on-whoseinner end is a' toothed pinion, k, which engages with the gear I of the yarn-beam? A red, Z, having-a head, m, at one end, is extended through a hole in'the spring d, and is pivoted or jointed to an arm, n, cxtended irom'oneof the swords of the lay. I would remark that the arm 0, the shaft 6, and the arms a'zi, I term the ,operstivelevcf' of the whiproller. The train of gcars'of'the yarn-beamiineludes the-gear l, the pinion'k, end the shaft 2'.
\ From the above, it will be seen that while the laj is in retreat, the said rod 1 willslide back through the spring, andn'hcn' the lay advances and beats the weft into the warps, the rod will draw upon the spring so as td tighten the friction-strap on its wheel. Thus, with my invention, no delivery of the yarn can take place at the beat of the sley, such delivery being due only to the increase of the strain or tension on the warps that 'may be produced from time to time by othcr'cnnses.
I make no claim to the combination of the friction-strap f, its wheel 9 and spring d, with the whip-roller- D, and its operative lever, the ynrn-beam O, and the train of gears thereof.
- What I claim, is- I The combination of the connection-rod Z, or the mechanical equivalent thereof, with the lay B, and the nicchnnism npplied to the whip-roller D and the yarn-beam C, such mechanism consisting-of the friction-strap ,1, its wheel (rand spring d, and the operative lever and train of gears, as explained.
