LOOM,

STEPHEN C. MENDENHALL, OF RICHMOND, INDIANA,

AND OBIID KING AND EZRA KING,

OF SALEM, IOYVA.

HAND-LOO1VL Specification of Letters Patent No. 9,388, dated November 9, 1852.

To all whom, it may concern;

Be it known that I, STEPHEN C. MENDEN- HALL, of Richmond, in the county of Wayne and State of Indiana, and Onnn KING and EZRA KING, of Salem, in the county of Henry and State of Iowa, have invented certain new and useful Improvements in Looms; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification.

Our invention consists first in effecting a movement of any number of heddles and varying the number of the same by a motion derived from the lay, so as toproduce fabrics of two or more leaves with the same loom without the use of cams and without removing any part of the machinery; and second, in effecting a throwing of the shuttle by an inclined plane action, which operates independently of that for shedding the web.

Of said drawings Figure 1 is a transverse vertical section, showing the treadle stick or finger depressing one of the treadles to the fullest extent; Fig. 2 a view of the mechanism for effecting a movement of the heddles, detached from the lay and breast beam; Fig. 3 a detached view of finger shaft and finger with the springs for recoiling the same; Fig. 4 a view of the 'mechanism for effecting the throwing of the shut tle; and Fig. 5 a detached view of picker staff, showing the double inclined planes upon its end.

Similar parts in each of these figures are designated by the same letters of reference.

a, are the beams, b the stanchions connected together by the breast beam and other cross ties, which are constructed of such form and size as are suitable to support and sustain the moving portions of the machinery.

A are the treadles (which can be varied to any desired number as we can operate two or more of them at pleasure and can produce with the same loom fabrics of any number of leaves) swung from behind instead of from the breast beam as usual in hand looms from the arms B projecting down from the treadle tie C.

D are arms secured to the top of the treadles which serve as guides and abutments for the finger E to act against.

her when the lay is again on The mechanism by which we are enabled to operate any number of heddles and Vary the number of the same at pleasure with the same loom without the use of cams and without removing any part of the machinery consists and may be described as fol lows: F is the finger shaft which is constructed square at one end for part of its length the remaining part being a round shaft, cut through its square end is a mortise through which mortise pass and are secured a series of pins H which correspond in number to the treadles andserve as abutments for the wherve K to act against. On the top side of said square end are provided a series of notches I which are the same distance apart as the pins H but are less in number than the treadles, and suitably suspended 011 a fulcrum in the beam of the lay is a pawl J which falls into said notches so as to prevent the shaft F from moving in one direction while it is kept from moving in the opposite direction by a spring G. iittached to the square end of said shaft is an inclined plane 0. E is the treadle stick or finger which moves freely on the round part of said shaft but is kept close against the shoulder thereof by a spring G which spring also answers the purpose of causing said finger to act gradually upon the abutnients D and assume a position again when the lay is on its backward movement to operate against the abutment in the same manmovement.

Cut through the beam of the lay is a mortise into which is secufed the guide boards M M and it is provided with an in clined plane N. The guide boards are for the purpose of guiding the wherve K into the mortise of the finger shaft and the inclined plane N by its action upon the end of said wherve causes a movement of the finger and shaft at each backward movement of the lay in the following manner: 0n the backward movement of the lay, the wherve K, which is hinged to the underside of the breastbeam and provided with a spring L which keeps it close against the side of the board M, is guided by said boards so as to enter the mortise in said finger shaft and by acting against the inclined plane or by the action of the inclined plane upon its end causes it to force the finger shaft to slide the distance of one of the its forward notches I or in position to operate upon the next treadle, thus at each backward move ment of the lay the shaft F is moved one notch by the action of the wherve as described, in which position it is retained by the pawl J until the finger has operated a treadle and the wherve adjusts it again ready to operate the next treadle. After the number of treadles to produce the number of sheds required have been successively operated in this manner the inclined plane 0, causes the wherve K to slide up over it and under the pawl J which releases said shaft F and allows it to recoil to the starting point ready to repeat the same sheds. With this arrangement for effecting a movement of the heddles, it will be seen that to vary the number of heddles to produce any number of sheds of the web it is only necessary to prescribe the limit to which the fin ger shaft shall slide or recoil in the lay, and that said shaft can be adjusted so as to operate two or any number of treadles, by simply inserting a pin through holes pro vided on the lay beam at suitable distances apart for that purpose as represented in Fig. 2, or a bit of wood placed in the mortise in which the shaft slides so as to check it will answer the same purpose.

In the action of the treadle stick or finger on the treadles, there is this feature of difference between our arrangement and all other hand looms-z Our treadles are swung from behind instead of from the front so that the finger acts upon them at nearly a right angle, and the leverage can be increased to any extent, whereas in other looms when the treadles are swung from the breast beam, the finger acts at a greater angle and consequently proportionally diminishes its power to effect a movement of the heddles.

Our simple device for effecting the throwing of the shuttle back and forth when the web is shed b mechanism independent of that for shed ing the web operates upon the principle of the inclined plane. The

picker staff is pr vided with inclined planes near its fulcrum which are so arranged with and operated upon by hooks on the breast beam as to produce a very regular and perfect back and forth motion to the shuttle said hooks being self acting.

Q, is the picker staff formed with inclined planes Q, on each side of its fulcrum. This peculiar construction of the picker staff in combination with the hooks R, R, and spring T, have the efi'ect to raise said hooks alternately clear of the shoulders s, s, on said picker staff producing a catching or impinging of said hooks against the shoulders of said picker staff on the forward movement of the lay. Said hooks are hinged to the breast beam and has a spring T be tween them so that, they shall have both lateral and vertical play; when the picker staff is in the position represented in the drawing one hook is acting against one of its shoulders a, while the other hook which is held close against the round part of said picker staff by the action of the spring T, and is forced to slide up the inclined plane Q thus clearing the hooks of the shoulders of said picker staff alternately and effecting a sure throwing of the shuttle.

Having thus fully described our invention, what we do claim and desire to secure by Letters Patent is 1. The combination of wherve K operated by lay, inclined plane 0 and its guides M M, and adjustable pin W, or their equivalents B combined and operating as described, so that, we can operate and vary the number of heddles substantially as and for the purpose set forth.

2. Ne are aware that the picker staff has been operated by hooks alternately raised from the shoulders on the picker staff by pins on a vibrating slide operated by grooves in the treadle camthis we do not claim but we do claim the combination of the inclined plane, Q, on picker staff, spring T, and hooks R, R, for the purpose of lifting the hooks in the manner and for the purpose specified.

In testimony whereof we have hereunto signed our names before two subscribing witnesses.
