HEAD-MOTION FOR LOOIVIS.

SPECIFICATION forming part of Letters Patent No. 795,251, dated July 18, 1905.

Original application filed December 31, 1903, Serial No. 187,266. Divided and this application filed March 16, 1904. Serial No. 198,384.

To all who??? it may concern.-

Be it known that I, GEORGE S. Cox, a citizen of the United States, residing at Fitzwatertown. county of Montgomery and State of Pennsylvania, have invented a new and useful Improvement in Head-Flotions for Looms, of which the following is a full, clear, and exact description, reference being had to the accompan ying drawings, which form a part of this specification.

The object of my invention is to provide a head-motion for looms by means of which any device on the loom may be caused to operate intermittently and momentarily.

This application is a division of an application filed by me December 31, 1903, Serial No. 187,266, for an improvement in looms, wherein the invention forming the subject-matter of this application is described and shown as adapted to actuate mechanism for moving a yarn-carrier and a hair-selector alternately into operative relation with a nipper adapted to grasp the yarn or hair presented to it and pull it across the loom, whereby a cloth is formed having alternate sections of linen and hair weft. The invention forming the subjectmatter of this application is not, however, limited to the actuation of such or any weftchanging mechanism, but may be utilized for the purpose of operating any devices on the loom which it is desired to occasionally throw into action at predetermined times, and therefore the description and drawings of this application are confined to the novel mechanism embodying my invention and the mechanism immediately associated therewith.

The invention consists of the general or specific construction and arrangement of devices hereinafter described and claimed.

In the drawings, Figure 1 is a plan view of the shedding-motion and pattern mechanism for actuating the same, including my novel head-motion. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a front elevation of the same; and Fig. 4 is a detail view, in side elevation, of the pattern-drum, its shaft, and the gears and wheels carried thereby.

cured thereto the usual double-ended levers (Z (Z, &c., are theusual notched draw-bars of an ordinary shedding-motion, 0 the knife for actuating the draw-bars, and e the sliding rack, said knife and rack being connected, respectively, by connecting-rods ff with the opposite ends, respectively, of the doubleended levers 0 0.

gr is a flexible connection, the upper end of which is secured to the end of a lever h, pivoted on the frame. The lower end of the flexible connection g may be secured to any mechanism which it is desired to operate. The lever h is also connected by a wire it with one end of a draw-bar 2'.

j is a spring, one end of which is secured to the lever it, while the other end is secured to the frame. This spring normally holds the lever 7L, flexible connection 9, and drawbar 2' in their normally inoperative positions.

The draw-bar z' is made in two sections hinged together at a. The other end of the draw-bar is notched and adapted to be engaged by the constantly-reciprocating knife Normally, however, the knife 6 is ineffective to actuate the draw-bar 2', the notched end of the draw-barbeing held above the path of travel of the knife 6 by means of one end of a pivoted lever la, the other end of lever is resting on a support in such a manner that the boss k on lever k just clears the pattern-chain Z. When one of the lugs Z of the pattern-chain travels under the boss 70 and lifts the corresponding end of the lever is, the notched end of the draw-bard drops. Then the knife 6 actuates the draw-bar 6, thereby actuating the flexible connection g. As the knife crecedes the spring j returns the draw-bar 2' to its normal position.

The following mechanism is provided to actuate the pattern-chain: m is a sprocket-wheel loose on the pattern-drum shaft 9 and around which the pattern-chain extends. Also loose on the shaft r and secured to the sprocketwheel on is a toothed wheel 91. 0 is a disk secured to the shaft 0', said disk having a single tooth which at each rotation of the disk engages the toothed wheel a and moves it and the sprocket-wheel m a distance of one tooth. The shaft 0' has also secured to it a gear 7), meshing with a gear 1 on the pattern-drum shaft 7". The shaft w, besides carrying the pattern-drum r, has secured to it a ratchetwheel a, which is actuated by a two-part pawllever s, pivoted to an arm I), secured to shaft 6. At each oscillation of shaft 7), therefore, the pawl-lever a actuates the ratchet-wheel s, which, through shaft 1', gear (7, gear 7 and shaft 0, turns the toothed disk 0, and the disk 0 after the number of turns required to completely rotate it actnates the toothed wheel '12, sprocket-wheel m, and pattern-chain Inasmuch as the pattern-chain is moved but once in a number of reciprocations of the knife 6, the lug on the pattern-chain would continue to hold up the lever 7c, and the drawbar t' would be reciprocated at each oscillation of the shaft Z) during the complete revo.

lution of the disk 0, whereas the object is to cause said draw-bar and the mechanism actuated thereby to operate only once when a lug on the pattern-chain passes under the lever 71:. Means are therefore provided to move the pattern-chain lug from under the lever Z: immediately after the knife (,1 has actuated the draw-bar. This is accomplished by means of a bar t, pivoted to acrank a on the oscillating shaft 7), whereby the bar is constantly reciproeated. The bar is provided with a shouldered lateral projection t, which on its move meet from left to right, as shown in the drawings, strikes the lug and moves it from under the lever Z1, thereby permitting lever Z: to drop and lift the draw-bar /1 out of the path of travel of the knife (1.

To prevent the projection Z of the bart from moving the pattern-chain lug until the latter reaches the exact position necessary for it to assume to lift the lever L, I make the rear face i of the projection t inclined, so that when it strikes the lug the latter will force the bar tlaterally out, just as it completes its stroke, against the tension of the spring w, to which the free end of bar Z: is secured. In the reciprocations of the bar tthe lug 25 is not carried far enough toward the left to permit the shouldered part of the lug t to pass behind the lug Z until said lug Z has been moved into a position to lift the lever Z: to permit the draw bar (Z to drop. Therefore during a number of reciprocations of said bar 2? while the lug Z is close to the point where it is enabled to lift the lever 71? the inclined portion of the bar t strikes said lug and is forced laterally outward; but, as above stated, when said lug Z is at this point said part 25 is not carried far enough to clear the lug I; but after thelug J has been moved into a position to lift the lever Z: to permit the draw-bar to drop the knife moves from left to right, shifting the draw-bar, and the simultaneous movement of the bar t toward the left is sufiiciently far not only to cause the inclined portion t of the bar I: to strike the lug Z and be moved laterally outward, but also to cause the projection 25 to entirely clear the lug l, permitting the shouldered. part of the lug 25" to pass behind the lug l, whereupon the spring w draws the bar I; into its normal position, causing the projection z? to drop back of the lug and, as before described, move it out of operative position during the travel of the bar 23' from left to right.
