LOOM FOR \NEAVING DOUBLE-RULE. FABRICS.

SPECIFICATION forming part of Letters Patent No. 311,961, dated February 10, 1885.

Application filed November 7, 1882.

To aZZ whom it may concern:

Be it known that I, CHARLES COUPLAND, of Seymour, in the county of New Haven and State of Connecticut, have invented certain Improvements in Looms for \Veaving Double Pile Fabrics, of which the following is aspecification.

This invention relates to looms that are more particularly designed for weaving double-pile fabrics, but which, by omitting the pile-warp and the mechanism for actuating the warp, may be employed for simultaneously weaving two separate fabrics.

In the variety of looms to which my invention more particularly refers, there are employed an upper and lower race and fixed upper and lower shuttle-boxes placed in substantially the same horizontal planes as the races aforesaid, and provided with means for simultaneously projecting the shuttles upon said races from the shuttle-boxes. Such looms as heretofore constructed, however, have been incapable of weaving double-pile fabrics with their intermediate threads, and their shuttleprojectin g mechanism has been comparatively unstable and liable to get out of order.

The object of my invention is to provide a loom of the class indicated which will be suitable for weaving double pile fabrics that, when separated by cutting their intermediate pile-threads, will afford fabrics having a pile or velvet surface, and which will also be certain in its operation and not liable to get out of order during the vicissitudes of use.

My invention comprises certain novel combinations of parts, hereinafter fully particularized in the claims, whereby said objects are secured.

Figure 1 is a front view of the upper portion of the lay of the loo1n,with theinvention applied thereto. Fig. 2 is a View of one end of the said lay. Fig. 3 is a transverse sec tional view taken in the line 00 x of Figs. 1, 2, and 4t. Fig. 4 is a plan view of the end shown in Fig. 2, and Fig. 5 is a perspective detailed View. 7

At each end of the lay is a pair of shuttleboxes, A and 13, each being designed for the reception of a separate shuttle, and the one, B, being placed over the other, A. The shut- (Xo model.)

G is the top rail of the lay, and D is the I reed.

Extending down from the top rail, G, are a series of prongs or fingers E, the lower ends of which are bent inward or backward, as represented in Fig. 5, thereby forming a skeleton race in substantially the same horizontal plane as the bottoms of the boxes B. The prongs or fingers E are placed at such distance apart that their-lower parts, 6, will support the shuttle in passing over the same. The object of this skeleton race is to provide a means for supporting the uppershuttle during the move- -ments which are imparted to it in forming the upper web of the fabric without permitting the upper shuttle itself to run in contact with the warp. The lower-parts, e, of the skeleton race, constituted by the prongs or fingers E, are so arranged that the lower warp may rise between them in the operation of weaving, and are tapered in such manner that the warps may readily pass between them without catching, and a space should be afforded between their rear extremities and the reed in order to allow. the filling to draw down for the purpose of being beat up, all as will be read ly understood by those familiar wit-h the practical construction and operation of looms.

In'order that the two shuttles Aand Bmay be simultaneously projected over the races respectively formed by lay-beam a and fingers E, as indicated in Fig. 1, the horizontal partition f, which constitutes the bottom of the upper shuttle-box, and also the top of the lower shuttle-box on each end of the lay, is longitudinally slotted, as represented in Fig. 3, and at g in Fig. 4, and a peculiarly-constructed double picker, F, is arranged. to move through both of the said boxes. The upper part, on. of said picker traverses the upper shuttle-box, while the lower part,n,of said picker traverses the lower shuttle-box, the said upper and lower parts, m and n, of said picker F being connected by a neck, '1", as represented in said Fig. 3. Provision is made for the insertion of this double picker in place by means of an opening, 8, at the rear end of the partition f, the said opening extending the entire width of the interior of the shuttle-boxes, and being of a length, measured in adirection longitudinally of the shuttle-boxes, slightly exceeding the thickness of the picker F, so that the latter may be readily dropped into place and into position forlongitudinal movement within the shuttle-boxes.

A single picker-staff of the ordinary or any usual construction is arranged in substantially the samelrelation with the picker F as the common picker-staff is arrangedwith regard to a single picker of an ordinary single shuttlebox, so that the single picker-staff, acting through thedouble picker F, give simultaneous motion to the two shuttles as the same are projected from the two shuttle-boxes B and A, the two shuttles being thrown together and in unison alternately from the one pairof shuttle-boxes to the other.

In order to properlyguide, steady, and sup- 7 port the picker during its movement, there is provided a fixed horizontal guiding-rod, a which passes through a slot or opening of corresponding sizeand shape formed in the upper end of the picker, as more clearly indicated in Fig. 3.

Except for the purposes of the combinations hereinafter set forth in the claims, I do not in the Letters Patent to be issued on this application claim the herein-described skeleton race, inasmuch as the said skeleton race constitutes an elementin combinations claimed in certain other applications for Letters Patent filed by meas, for example, in my application filed November 7, A. D. 1882, and designated by the Serial No. 76,152. Further, I do not in the Letters Patent to be issued on this, my present application, claim with a double picker constructed and ar-.

ranged to simultaneously actuate the shuttles of both boxes, the one shuttle upon and over the lay-beam, the other upon and over the skeleton race, all substantially as and for the purpose herein set forth.

2. The combination of a lay having fixed double shuttle-boxes placed parallel and one above the other, the slotted partition f between said boxes. and the skeleton race placed above and parallel with the lay, with the double picker composed of theparts m n and neck 1", and arranged to be operated by a single picker-staff, the wholeconstructed and arranged substantially as and for the purpose herein set forth.

3. The combination of a lay having fixed double shuttle-boxes placed parallel and one above the other, the slotted partition f be tween said boxes, and the skeleton race placed above. and parallel with the lay, with the double picker composed of the parts at n and neck r,-and the guide or rod (1*, provided to steady said double picker, the whole constructedand arranged substantially as and for the purpose herein set forth.
