Definitions
- the instant invention provides supporting and adjusting means for warp stop motion by which a group of looms may be set to a desired standard quickly and accurately.
- FIG. 1 is a view in perspective of the adjustable supporting brackets for the left-hand end of a warp stop motion as seen from the side and slightly to the rear;
- FIG. 2 is a view of the mechanism of FIG. 1 as viewed from the front;
- FIG. 3 is a sectional view of the pivotal point of the stop motion shelf
- FIG. 4 is a left hand elevation of the support bracket showing the horizontal and angular scales
- FIG. 5 is an elevation similar to FIG. 4 showing the vertically movable bracket and scale
- FIG. 6 is a cross section of the front warp support showing the novel clamping means.
- FIGS. 1 and 2 a single loornside 20 is shown with a warp stop motion, generally designated 21, supported thereon. It will be understood that the stop motion 21 extends across the full width of the loom to a second loomside (not shown) and that a set of adjustable supporting parts, similar to those to be explained, are present on the right-hand side.
- the warp stop motions applicable to the instant invention may be either electrically or mechanically operated for equally beneficial results.
- Detector bars 22 are held in spaced alignment by an end cap member 23 which is supported above a slidable bracket 24 by posts 25 and 26.
- the slidable bracket 24 is adapted to hold a series of center rods 27 and a rear warp support 28 in any known manner and to have a front warp support 29 fastened thereto in a manner to be explained below.
- the slidable bracket '24 is adjustably fastened to a stop motion shelf 30 by a bolt 31 extending through an adjusting slot 32.
- the shelf 30 has an upwardly directed surface 33 on which the bracket 24 may be moved in a generally horizontal plane to positions toward and away from the loom harness (not shown).
- the surface 33 is scored in some manner to form a numerical scale 34 and the bracket 24 has an indexing point 35 directed toward the scale 34 and movable therealong.
- a shoulder member 36 (FIG. 2) is secured to the loomside 20 with a step 37 resting upon the loomside upper surface 38 for stability.
- a vertical scale 39 fastened to the shoulder member .36 by a screw 40 is for determining the relative vertical position of the movable parts.
- a shelf supporting bracket 41 is fastened to the shoulder member 36 by a bolt 42 extending through vertical slots 43 and -44 which allow settings of variable heights (FIGS. 4 and 5).
- the bracket 41 extends angularly to form a bifurcated arm 45 having a generally horizontal surface 46 disposed adjacent the edges of the scale 39 as shown in FIGS. 1 and 5 for indicating relative heights of the movable bracket 41.
- a jack screw 47 is threaded downwardly through the arm 45 and bears upon the shoulder member 36. By turning the screw 47, variable adjustments may be made to raise and lower the bracket 41 to conform to desired readings on the scale 39.
- the stop motion shelf 30 is pivotally fastened to the bracket 41 by a bolt 48.
- a conic boss 49 on the vertical surface of the bracket 41 is received by a mating recess 50 in the shelf 30' (FIG. 3).
- the boss and recess allow pivotal motion and support of the shelf 30 without loss of position.
- the bracket 41 has a rearwardly extending portions 51 containing a bolt hole 52 and an indicating finger 53 directed toward the rear of tthe m (FIGS. 4 and 5).
- An adjusting arm 54 which extends downwardly from the shelf 30 contains an arcuate slot 55 in an indexing relationship with the bolt hole 52 (FIG. 4).
- a locking bolt 56 extending through the hole 52 and the slot 55 will hold the shelf 30 in any angular position when the bolt is tightened.
- the shelf 30 has, near its rearward end, a depending protractor scale 57 movable in an are adjacent the finger 53 which will indicate the angularity of the shelf 30.
- the front warp support 29 (FIGS. 2 and 6) is formed in an inverted U shape and extends the full length of the warp stop motion 21.
- the warp support 29 is fastened to the slidable bracket 24 by an internal clamping member 58 which is inserted into the support 29 with pressure being applied by a screw 59 threaded into the bracket 24.
- a washer combination 60 (FIG. 6-) locks the support 29 into place and allows removal by simply loosening thescrew 59. This facilitates the application and removal of the warp support as bolts and nuts do not need to be taken off and the support itself does not require holes or slots for fastening purposes.
- the adjustable brackets of the instant invention allow movement of the warp stop motion horizontally, vertically and also angularly to the warp line.
- the three graduated scales 34, 39 and 57 permit quick and accurate settings to predetermined points within the range of movement. When a combination of settings is determined as the optimum for any particular cloth construction, that combination may easily be applied to any number of looms by use of the graduated scales.
- an adjustable positioning means which comprises (a) supporting members for fixedly adjusting said stop motion vertically, horizontally and angularly, said supporting members including (1) a pivotally movable stop motion shelf,
- said shelf having a fiat upper surface adjustable angularly and vertically
- the adjustable positioning means according to claim 1 which further includes a vertically slidable shelf supporting bracket.
- the adjustable positioning means according to claim 2 which further includes a vertically disposed jack screw for providing variable adjustment to said shelf supporting bracket.
- said graduated indicating means includes a height indicating surface upon said shelf supporting bracket movable vertically relative to a fixed graduated vertical scale.
- said adjustable positioning means includes a depending calibrated protractor scale upon said stop motion shelf, and said shelf supporting bracket includes an indicating finger directed toward said protractor scale.
- said adjustable positioning means includes a longitudinally extending scale upon said stop motion shelf, and said slide bracket carries an indexing point directed toward said longitudinally extending scale.
- At least one of said warp supporting rods defines an inverted U-shaped cross section, and internal clamping means disposed upwardly into said U-shaped cross section for fastening said warp supporting rod removably to said slide bracket.
- said shelf supporting bracket includes a conic boss, said stop motion shelf having a mating recess for receiving said boss for pivotal movement thereon.
