CONRAD RODER, OF OERALVO, KENTUCKY, ASSIGNOR TO HIMSELF AND .1. T. ILER, OF SAME PLACE.

FANCY j LCOM.

Specification of Letters Patent No. 25,869, dated October 1.8, 1859.

l.To all whom it mag/concern:

Be it known that I, CONRAD RODER, of Ceralvo, in the count-y of'Ohio and State of Kentucky, have invented a new and use-ful Improvement in Looms; and I do hereby declare that the following is a full and clear description thereof, reference being had to the accompanying drawings and to the letters of reference -marked thereon and made to form a part of this specification.

My invention has relation to the mode of operating the harness in fancy looms which employ a pattern chain on cylinders; and my invention consists in the construction and arrangement, of the hooks, from which the harnesses are suspended, in combination with an adjustable bed plate and elevating sash, by means of which said hooks are rendered self adjusting with reference to said sash, without the aid of springs or catches of any kind.

ln reference to the accompanying drawings Figure 1, is a perspective view of my improvement showing that portion of the loom which operates the harnesses, with all its parts arranged for operation. Fig. 2, is a vertical sectional view of the same.

(A) represents a frame which may be adjusted upon a loom frame, in proper position with reference to the working parts of the loom; (a) are cards having in them per.- forations (c'a) and being provided with pins or cams, (b) which are adjustable with reference to the perforations (a), and capable of being changed to harmonize with the pattern of the fabric to be woven-so that by arranging said cams, to correspond with the drawing, for the desired pattern, the fabric may be woven in perfect harmony with said drawing, even by an inexperienced operator. rlhe cards (a) are arranged upon an endless flexible belt or band: in such manner that more cards may be added to said belt, or, a portion of said cards removed from the belt as may be required; (C) is a cylinder, having bearings in the frame (A) and being formed with projections (c) at its corners, as fully shown in Fig. 2, and its dimensions being such, that its sides may correspond with the size of the cards (M -the recesses (0') of the cylinder (C) are adapted to receive the inner ends of the cams as the cards (a) pass overl the said cylinder (C). n

D is a cylinder, having bearings 1n the adjustable posts (D), so that by moving the posts (D), and securing them at desired points, to the base timbers (A) of the frame the cylinder (D) may be so adjusted to any required space'between the cylinders (C, D). The cards (a) after being secured to a flexible band, may be arranged upon the cylinders (C, D) as represented, and as said cards are increased or diminished upon the band, ,the cylinder (D) will be adjusted to correspond with the operating cards, as before described; (d) is a reciprocating bar, formed with catches (CZ, Z)-so `arranged that by elevating or depressing said bar, the cylinder (C) may be operated in either direction, thereby reversing the motion of the cards when it may be required; (e) is a cord attached to the lower catch (ay) and arranged upon pulleys (e) as clearly shown in Fig. l, and to the end (6) of the cord is attacheda weight (em). When it is required to operate with the upper catch (cZ), so as to move the cards (a) forward, the weight (em) will be suspended upon a hook of the frame (A) so as to free the cord (e) and allow the catch (fl) to operate the cylinder (C) and when it may be required to reverse the motion of the cards (a), the weight (am) will be removed from said hook and allowed to act upon the cord (c) thereby elevating the bar so that the catch (CW) may act upon the under side of the said cylinder (C) as is clearly shown in Fig. 2. The bar (d) may be operated by means of the sash through the medium of a bent lever (Gr), which is pivoted to the post (g) of the frame (A) at (g) as fully shown in Fig. l.

(f) are hooks from which the harness of the loom may be suspended. Their upper ends are formed with the catches (it, h) and their lower ends being formed with projections (2), which pass loosely through apertures in the bed plate (F), and with shoulders (71') which rest upon said bed plate (F); thus leaving the forward portion of the base of the hooks free from the bed plate; the harness of the loom being suspended from the point (zw) of the hooks (f); the hooks will be constantly inclined forward in the direction of the cards (a), by means of the weight of the said harness and if necessary, of other weights attached thereto, so that when the hooks (f) are free from the cams (o) they will always be in the proper position to be elevated by the sash (E) without the aid of springs or catches of any kind. (H) is a bar, pivoted to the frame (H) and provided with a weight (I); the said bar (H) is arranged to rest or bear upon the planes of the square head (C) of the cylinder (C) by means of which regular action of the cylinder (C) may be secured, so as to bring the cams (b) to bear upon the hooks (f) in a regular proper manner.

(E and J) are sashes arranged to work vertically in grooves of the frame (A) and constructed with reference thereto in such manner as to be allowed a certain degree of lateral adjustment, said adjustment being effected by means of the guide plates (j) and set screws (j); vthe sashes (E, J) are provided with inclined lifting bars (lo, c,) which are dove-tailed into said sashes in such manner as to be adjustable with reference to the hooks as is clearly represented in Fig. l, and by means of which, through the medium of the hooks (f) the harness containing the chain of the woof may be operated; the bar (v) being arranged with reference to the catches (L), and the bar (7e) with reference to the catches (L) of the hooks The operation of my invention may be described as follows: A suflicient number of cards (a) for the completion of the pattern Y to be woven, being arranged upon the ieXible band, the cams (b) belng arranged in the perforations (a) to correspond with the drawing of the said pattern, and the chain or warp being properly adjusted 'in the harness of the loom, with reference thereto, and the bar (d) being in the position shown in Fig. l; and the working parts of the loom bein@ made to operate in the usual manner; tIie lever (L) will be depressed thereby elevating the sash (E) and hooks (f) in the manner before described; the lever (L) is now released and the sash permitted to fall, by means of which, through the medium of the bent lever (Gr), bar (al) and catch (cZ) the cylinder (C) will be made to rotate one fourth a revolution, thereby bringing the first card (a), of the pattern to be woven into proper position for its cams (b) to bear against the hooks (f)-the lever (L) will then be operated again, and the hooks (f) which are free from the cams (b) of the iirst card will be elevated as before described, thereby elevating the proper harness with their contained threads of the chain. The lling may now Vbe introduced; and in cases where the pattern requiresl the introduction of several threads of one or more colors, the lever (L) will be operated until a change in the pattern occurs-when the lever (L) will be operated as before described, another card n(a) be brought in position for its cams to bear upon the hooks (f) by means of which the next ligure of the pattern may be woven as before described; the presentation of the cards (a) may be reversed when required in the weaving of certain patterns by releasing the weight (em), and allowing it to act upon the cord (e), thereby elevating the bar (CZ) and bringing the catch (d) to operate upon the under side of the cylinder (C) as before described. When the hooks (f) are free from the cams (b) they will be sustained always, in position to be elevated by the bar of the sash (E), by means of the weight of the harness and the shoulder as previously set forth, and as clearly shown by the red lines in Fig. 2.

I am aware that the harness in Jacquard and other looms has been operated by lifting hooks actuated by pattern chain and therefore I do not claim broadly such mode of effecting this result; but

Vvhat I do claim and desire to secure by Letters Patent of the United States is- The combination and arrangement of the double catch hooksv (L, L,) adjustable guide plate j the sash E and J with the lifting' bar if; in the manner and for the purpose herein described.

In testimony of which invention I have hereunto set my hand in presence of;

CONRAD RODER.
