LAPPET-LOOIVI.

Specification of Letters Patent.

Patented Dec. 12, 1905.

To all whom, it nrzy concern:

Be it known that we, ALBERT A. GORDON,

tions of a pattern-surface, and more particularly relates to improvements in a supplemental mechanism adapted to be applied to a lappet-loom and forming a lockingmechanism operated automatically to hold one needle-bar or both needle-bars in raised position.

Our invention consists in certain novel features of construction of our improvements, as will be hereinafter fully described.

We have only shown in the drawings portions of a lappet-loom with our improvements applied thereto sufficient to illustrate the na: ture of our invention.

Referring to the drawings, Figure 1 is a sectional front view of portions of a lappetloom and our improvements applied thereto, taken at a point indicated by line 1 1, Fig. 2, looking in the direction of arrow a, same figure. Fig. 2 is a section on line 2 2, Fig. 1, looking in the direction of arrow 6, same figure. Fig. 3 is a detached plan view of the two needle-bars and our locking mechanism combined therewith. Fig. 4 shows a different position of the parts shown at the right in Fig. 3. Fig. 5 is a section on line 5 5, Fig. 4, looking in the direction of arrow 0, same figure. Fig.6 corresponds to Fig. 4, but shows a different position of the parts. Fig. 7 is a section on line 7 7, Fig. 6, looking in the direction of arrow d, same figure; and Fig. 8

is a section on line 8 8, Fig. 3, looking in the.

direction of arrow 6, same figure. Figs. 3 to lower ends and mounted on the rock-shaft 7. The lay-beam 5 carries the reed 8.

There are two needle- bars 9 and 10, carrying downwardly-extending needles 9 and 10', respectively. The needle- bars 9 and 10 move with the lay on its forward and backward movement and also have a vertical and a longitudinal movement independent of the lay in the ordinary and well-known,way. A longitudinal movement is communicated to each needle- bar 9 and 10 through connectors 9 and 10, connected with a pattern mechanism. (Not shown.)

There are two vertically-moving rods 11, having suitable bearings 11. A rod 12 extends between the vertically-moving rods 11 and is attached at its ends'thereto and carries thereon at each end a roll 12, adapted to travel 7 in a cam-groove 13 in a stationary stand 13, attached by a bracket 14 to each of the loomframes 1. (See Figs. 1 and 2.) A bar 15 carries a series of shuttle-guide needles 15, extending up through the lay-beam 5, and is adapted to be raised and lowered as the lay moves back and forth through a roll 16 on a stud 17, traveling in the cam-groove 13" in the plate 13. The stud 17 is secured to a hub 17, loosely mounted on the vertically-moving rods 11 and having attached thereto the ends of the bar 15, carrying the guide-needles 15.

On the upper end of each vertically-moving rod 11 is secured a hub 18 on a plate or bar 18. (See Fig. 5.) The bar 18 has secured in 5 each end thereof a vertically-extending rod 19. On each rod 19 is mounted to have a vertical motion thereon the hub 20 on a stand 20, upon which are supported to move with and have a longitudinal motion thereon the 9 needle- bars 9 and 10, which are held in position and guided by undercut lugs 21, secured to the upright part of the stands 20. (See Fig.5.) Each of the stands 20 has thereon the side extension or engaging projection 20". On the outside of the stands 20, at each end of the needle- bars 9 and 10, is a stand 22, secured to and movable with the lay, which has thereon a bearing 22 (see Fig. 1) for a vertically-extending rocking shaft 23. The shaft 23 (shown at the right in Fig. 1) has fast on its upper end a hub 24, which has extending out therefrom three arms 24, 24, and 24. (See Fig. 3.) Each- arm 24, 24", and 24 has projections 39.

at its extreme end a bevel-shaped downward extension 245*, 243". and 24. (See Figs. 5 and 7.) Connected with one of the arms, as 24', is a connector 25 (see Fig. 1) to an anglelever 26, pivoted at 27 on the lay. The other arm of the angle-lever 26 is connected, through a connector 28, to one end of a lever 29, pivoted at 30' on the rocker-iron 30. The opposite end of the lever 29 is connected, through a connector 31, with an indicator-lever 32, pivoted at 33' on the stand 33 and carrying a roll 34, which rests on the rotary pattern chain or surface 35. (See Fig. 2.)

On the lower end of the shaft 23 (shown in Fig. 1 at the right) is attached an arm 36. A connector 37 extends from the arm 36 to an arm 38, the hub 38' of which is fast on the lower end of the shaft 23. (Shown at the left in Fig. 1.) Upon the upper end of the shaft 23 (shown at the left in Fig. 1 and also shown in Figs. 3 and 8) is fast a hub 39. and extending out from the hub 39 are two arms 39' and 39". (See Fig. 3.) The arm 39" has a downwardly -extending bevel projection thereon 39", (see Fig. 8,) and the arm 39 has oppositely -extending projections 39*" at its end having thereon downwardly-extending bevel (See Fig. 8.)

A spring 40 is attached at one end to a projection 39' on the hub 39 (see Fig. 3) and at its other end to a stand 41 on the lay. (See Fig. l.)

The operation of our improvements in locking mechanism for the needle- bars 9 and 10 will be readily understood by those skilled in the art.

In lappet looms of the class above described in weaving fabrics thereon of different patterns one needle-bar is at some time in its lower operative position while the other needle-bar is in its raised inoperative position, and vice versa, and also at some time both needle-bars are in their raised inoperative position when the plain fabric is being woven. By means of my improvements either needlebar or both needle-bars are held up or in their raised inoperative position at predetermined times through the indications of the patternsurface, as will be well understood by those skilled in, the art.

In the operation of the loom a longitudinal motion is communicated to the needle- bars 9 and 10 at predetermined times, according to the indications of the pattern-surface, through intermediate mechanism, to the connectors 9" and 10" in the usual way. Through the rolls 12' traveling in the cam-groove 13' an upward movement is communicated to the verticallymoving rods 11 at every forward movement of the lay and a downward movement at every backward movement of the lay. The stands 20, supporting the needle- bars 9 and 10, are raised and lowered with the vertically-moving rods 11 through the bars 18 unless either one or both of the stands 20 at each end of the needle-bars when in raised inoperative position are locked in said raised position by the engagement of one or more of the arms 24', 24", and 24', with the lugs 20" on the stands 20 at one end of the needle-bars and the engagement of the lugs 20" on the stands 20 at the opposite end of the needle-bars with the arms 39' and 39". The movement of the arms 24', 24", and 24' and of the arms 39' and 39" to engage the lugs 20" on the stands 20 to lock one or both of the needle- bars 9 and 10 in their raised inoperative position or to release one or both of the needle-bars to allow them to drop into their lowered operative position is controlled by the pattern-surface 35 through connections to the arm 24', as above described.

By making the downward extensions on the engaging ends of-the arms 24: 24" 24' and 39' 39" with beveled-shaped engaging edges, as shown in Figs. 5 and 8, the raising of the stands 20, carrying the needle- bars 9 and 10, will not be interfered with by the lugs 20" on the upperends of said stands engaging or striking against the under side of said arms in case said arms or any of them happen to extend over the lugs 20" on the stands 20, for the lugs 20" engaging the bevel edges on said arms will rotate the hubs carrying said arms and the shafts 23, on which they are secured, against the action of the spring 30 to move said arms out of the path of the lugs 20" until they have been raised to their highest position.

It will be understood that the details of conholding the needle bar or bars in raised position, comprising locking-arms having a pivotal movement in a horizontal plane, and having downwardly-extending inchned or bevelshape projections on their engaging ends, and

means for moving said locking-arms, substantially as shown and described.
