GUIDE-LEVER FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 643,657, dated February 20, 1900.

Application filed November 18, 1899. Serial No. 737,477. (No model.)

To all whom it may concern.-

Be it known that I, LOUIS A. KING, a citizen of the United States, residing at Salem, in the county of Essex and State of Massachusetts, have invented a new and useful Guide-Lever for Looms, of which the following is a specification.

My invention relates-to take-up devices for looms, and more especially to means for guideing the cloth to the take-up roll and causing it to be tightly and regularly wound thereon, the object of the invention being to provide guide pressure-levers for the cloth-rolls especially adapted for looms for narrow ware, but serving well for all classes of looms.

With this object in view my invention consists in the improved construction, arrangement, and combination of parts hereinafter fully described and afterward specifically pointed out in the claims.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, having reference to the accompanying drawings, forming part hereof, in which-- Figure 1 is a view of my invention in side elevation and of so much of the loom to which it is applied as is necessary to illustrate its connection therewith. Fig. 2 is a view of the same parts in rear elevation, the frame of the loom, the sand-roll, and the cloth-roll being broken away to narrow the figure. Fig. 3 is a top plan view. Fig. 4c is a fragmentary detail view, in side elevation, of part of the frame of the attachment with the part of the loom-frame in section. Fig. 5 is a plan View of the lever-supporting arm detached. Fig. 6 is a view of the same in elevation. Fig. 7 is a sectional View of the same on the broken line 7 7 of Fig. 6, the withdrawing-arm being shown in dotted lines. Fig. 8 is a face view of one of the spring-adjusting washer-plates detached.

Like numerals of reference mark the same parts wherever they appear in the several figures of the drawings.

Referring to the drawings by numerals, 1 indicates one of the cross-beams of the frame of the loom, to which is secured the frame 2 of the attachment, the frame 2 being provided with a rigid hook 3 to engage the top edge of beam 1 and with a pivoted hook 4 to engage the bottom edge,said hooks being held in engagement by a hand-screw 5,threaded through frame2and bearingnpon beam 1. The frame 2 is also formed with an upright curved arm 6, having a curved slot 7, and a horizontal arm 8, havinga round opening 9, the curved slot 7being in an arc of a circle having the opening as a center.

10 indicates an arm or bar pivoted in opening 9, said arm being formed with a boss 11, having a journal 12 on one end having a bearing in said opening, an oppositely-projecting boss 13 at its opposite end having a journal 14, and on its opposite side with a smaller journal or pin 15, which is seated in and projects through the curved slot 7 and provided with a handle 16.

17 indicates a washer or disk mounted on boss 11, adjacent to arm or bar 10, having radial notches 18 in its periphery and secured against rotation by a bolt 19, engaging in one 'of said notches and a notch 20 in the fixed arm 8. The arm 10 is secured in its bearing by a pin 21 and is normally pressed downward by a spring 22, coiled around boss 11,

having one end, 23, engaged over the edge of said arm 10, and the other end, 24, in one of the notches 18 in washer 17, the tension of the spring being regulated by engaging the last-mentioned end in different notches 18 or by turning the washer 17. The arm 10 at its pivotal end is at a distance from the fixed horizontal arm 8 equal to the length of boss 11, but is bent or offset, so as to bring its outer end against thesaid arm 8, as clearly shown in Fig. 3. Uponthe boss 13, adjacent to the outer end of arm 10,'is,a disk 25,, similar in construction to disk 17 and having similar radial notches 26 in its outer edge, said disk being held against rotation by a bolt 27, engaging in one of said notches 26, and a notch 28 in the outer end of arm 10.

29 indicates a lever pivoted on journal v14 of boss 13 and secured against displacement bya pin 30, said lever being normally pressed inward at its upper end by a spring 31, coiled around the boss 13 and having one end, 32, engaging over the outer edge of the lever, and the other end, 33, in one-0f the notches 26 of disk 25, the tension of the spring being regulated in the same manner as before stated with reference to spring 2 The upper end of lever 29 is bent inward at a right angle, forming a hook 34, which engages over the journal 35 of the usual cloth-roll 36 of the loom, said roll beingloosely journaled in slots (not shown) in the side frames of the loom, part of one of which frames is shown at 37 in Fig. 2.

38 indicates the usual roughened tensionroll, commonly known as the sand roll, around which the cloth 39 is caused to pass as it is led to the cloth-roll 36, said sand-roll having journals -lO,which have fixed bearings in the side frames.

The parts being constructed and adjusted as described, the sand-roll and cloth-roll are driven in any usual manner in order to wind the cloth upon the cloth-roll.

It will be obvious from the foregoing that the normal tendency of arm 10 will be to move downward on its pivot under the tension of spring 22, the direction of such tendency beingindicated by arrow X in Fig. 1, while the normal tendency of lever 29 will be to moveinward, as indicated by the arrow Y in Fig. l. IVith the hooked upper end 34 of lever29 engagingover the journal 35 of the cloth-roll 36 this roll will be yieldingly pressed and held against thesaid roll 38,such pressure being the same whether the roll has a large or small amount of cloth upon it, the downward tendency of arm 10always pulling downward on the lever 29 and causing hook 34: thereof to press the cloth-roll downward and theinward tendency of lever 29 always keeping the hook in proper engagement with journal 35. This pressure of hook 35 will cause the cloth to be.

tightly wound on the cloth-roll, and as the tendency is now to weave verylong cuts this feature is valuable, economizing in requiring a less number of cloth-rolls and in the time required in taking oif full ones and putting on empty ones.

It will be understood that all the mechanism of my attachment is duplicated, there being an attachment near each end of the loom, and the attachments being readily adjustable as to position on cross-beam 1 they can be placed to suit any width of cloth which the loom can accommodate, the levers 29 serving as end guides for the cloth as it is wound upon the roll, thus assuring straight-ended cuts.

While I have specifically described the construction of the various details, it is obvious that many slight changes might be made therein without departing from the spirit and scope of my invention.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent of the United States, is

1. An attachment for looms comprising a frame securable to the loom-frame, an arm pivoted thereto and yieldingly pressed downward at its outer end, and a hooked lever pivoted to the end of the arm and yieldingly pressed inward, its hooked end being adapted to engage over a journal of the cloth-roll, substantially as described.

2. An attachment for looms comprising a frame securable to the frame of the loom, an arm pivoted thereto, a spring engaging the attachment-frame and the arm and normally pressing the arm downward, a lever pivoted to the arm and having a hooked upper end, and a spring engaging the arm and lever with a normal tendency to maintain the hooked end in engagement with a journal of the clothroll, substantially as described.

3. An attachment for looms comprising a pair of levers having hooked outer ends, springs for normally maintaining said hooks engaged over the journals of the cloth-roll and drawing said levers downward, and adjustable fastenings for securing the levers at different positions on a cross-beam ot' the loom, whereby they also act as side guides for the cloth as wound upon the cloth-roll, substantially as described.

4. In an attachment for looms, the combination with a frame adapted for attachment to the loom-frame and provided with a round opening and a curved slot in an are having the opening for a center, of a horizontallydisposed arm pivoted in the opening, a pin at its outer end seated in the curved slot, a lever pivoted to the outer end of the arm and having a hooked upper end, and springs tending normally to press the horizontal arm downward and the lever inward, substantially as described.

5. In a loom attachment, the combination with a frame adapted to be secured to the loom-frame and provided with a round opening and curved slot, of an arm pivoted in the opening, a pin on the arm seated in the slot, a boss on each end, on opposite sides of the arm, a hooked lever pivoted to the boss at the outer end of the arm, a notched disk on each boss secured against rotation, and a spring coiled around each boss having one end engaged in one of the notches of the respective disks, one of said springs bearing downward on the arm, and the other bearing laterally against the hooked lever, substantially as described.

LOUIS A. KING.
