. BEAM-SUPPORTING lixcnaaNs.

Application med November 22; 1923; lSerialv No. 676,225.

To all who/m, t may fao/noem? Be it known that I, WILLIAM citizen of the United States,

South` Bethlehem, in the county of S. WELLS, a Lehigh and State of Pennsylvanialhave 1nvented/i certain new and useful.- Improvements/1n Beam-Supporting Means, of which theffollowing is a specification. l

This invention relates to means for sup, porting rotaryr beams, as tliewarp beam in has for itsfobjeet to provide a beam-supporting means which can be quickly and easily yadjusted bothpup .and down tochange the elevation ofthe beam or laterally (i.e.',I longitudinally of the axis of the beam)- so as to accommodate beams varying in Width, and which shall afford a strong and vrrigid support for thebeam.

In the drawing,

Fig. `l is a side elevation of the rear partz of a loom having the improved supporting. means attached thereto.; r

' Fig. 2 is a plan View of the end ofz the said supporting means and Figs. 3 and 4 are "sectional views on lines 3-3 and 4 4, respectively, Fig. l.

In the following description, only one end of the beam 'beingsh'own in the drawin only one ofthe support-ing means is re erred to, it being understood that vsaid supporting meansv will lusually be duplicated in practice, there being one for each end of the beam.

a is the loomv frame, b is a beam and c its gudgeon, and d-is the usual rope` round the flanged head bof the beam and'having its rear and forward ends carrying weights d and d, the former of which maintains the tension on thel warp A and the latter of which by contacting with the floor allows in the known way .for slippage to take place between the rope and the beam; whether this thus-weighted rope orany other means for maintaining tension on the warp is employed is of course immaterial.

Each side of the loom frame is provided with a. pivot, *here in the form' of a. long stud e, projectinglaterally and horizontally, being through ahole in said side of the frame and having nuts .f-:to clamp the same. On this pivot is movable up and down pivotally and also longitudinally thereof a rearwardly extending arm g having its top and bottom edge portions straight and preferably residino yat having a T-shaped w'zy h rigidly f held in place by extendingflanged at bothIl sides (so-.as to present substantlally an I-'section, Figs. 3 and 4), as 'at l Il vn the upper flanged edge lg of the arm is arranged a block h whichis fitted thereto,

h formed therein,

to receive said ed e. is block -has an up.-y

,- standing U-shape or open bearing z' tore- 1.ceiye the beam gudgeon 4and -it is also equipped with a set-screw j which may bind against thev arm; the block is adjustable 'lengthwiseof the arm and when so adjusted `may be heldby the` set-screw. The free end of the arm is supported as follows: v

A bracket c is bolted to the sideA o-the'TO loom frame belowstud e and isequippedf with a vertical pinl forming a pivot. On g this pivot is pivotally movable anotherarm 'in which preferably has its Vfree orrea-r end y hbent upward and formed with a vertical bearing m. On this' bearing rests a. nutn which it is-convenient` to form with an `extended circular portion or Wheel/'lt' affording a hand-grip. Ayertical screw lo is threaded into the nut4 and extends freely 80 through (i. e., without threaded engagement with) vthe bearing; p is a lock-nut on. n the screw below the bearing. At its upper end the screw has pivoted thereto, as on the 'horizontal bolt g, 'a slide 1 which is fitted 8 to the lower flanged edge g `of the-larm g, y having an inverted T-sha d way 1" formed Y therein to receive said e ge.

`The connectionbetween the two armsg and m which isv aiordedby screw o and. ff`

slide r is one capable ofrotation ony a vertical axis relatively to m and of sliding relc ative'ly to andl lengthwise of .,g.` iConsequently lthe #lateral movements of ,the two arms vv(the one rectilineal and the `other pivotal) in adjustingthe supporting means according to the length of the beam to be supported occur in unison, ksaid connection turningvin arm m and shifting'lengthwise of arm y. Whenthe -nut is lscreilved up tight against bearing m ofpa'rm m, so that the. bearing is clamped between p and n, the entire structure is held rigid. i

By turning the nut n, nut p being released, the screw 0 can be fed up and down 105 thus to raise or lower arm g and consequently place the beam at any. desired elevation. v y

lA bend is shown at g* in arm g (Fig. 2). This, taken with the fact that the stud 110 may be arranged to project inwardly or outwardly from the side of the loom frame and the two arms g may be changed about, makes it possible to use the improved supporting means to support beams varying from a length which would bring the ends thereof between the sides of the frame to a length which would bring their ends outward ofsaid sides.

The connection o-r also makes it possible for the weaver to quickly lower the supj'io-rting means so as to bring both weights d fl against the floor and so relax thel tension on the warp, as when the loom is left standing over night, and also quickly restore said means to its previous elevation when the weaving is resumed.

The improved supporting means also adapts the loom to be quickly converted for operation either with or without the usual whip-roll s being used to support the warp:

So far as lateral adjustment is concerned my invention comprehends broadly a beam supporting means including two arms, as g and m, one of which is substantially horizontally shittable, and the other of which is pivotally movable on a substantially vertical axis, on a. fixed structure, as a-e, and a pivotal coupling (of any kind) having its axis substantially .vertical and connecting portions of the arms remote from said structure and shiftable along one arm.

Having thus fully described my invention what l claim is:

l. ln combination, a fixed struc-ture and a beam-supporting means including' two arms one of which is substantially horizontally shiftable, and the other of which is pivotally movable on aI substantially vertical axis, on said structure, and a pivotal .coupling having its axis substantially vertical and connecting. portions of said arms remote from said structure and shiftable lengthwise of one arm.

Q. In combination, a fixed structure and a beam-supporting means including two arms one of which is substantially horizon- .tally shiftable, and the other ot which is Langeac tively to the other up and down, and a connection connecting portions of said arms remote from said structure and comprising pivotally connected parts one of which is shiftable along one arm and the other turnable on asubstantially vertical axis in the other arm.

4. In combination, a. xed structure and a beam-supporting means including two arms one of which is substantially horizontally. shiftable, and the other of which is pivotally movable on a sul'istantially vertical axis, on said structure` and means, pivctally connecting the two arms in their various positions and having its pivot substantially vertical, 'for securing them in rigid relation to each other.

In combinationya fixed structure and a beam-supporting means including two arms one of which is substantially horizontally shiftable, and the other of which is pivotallv movable on a substantially vertical axis, on said structure, means, shiftable along and held against turning relatively to one. arm but turnable in the other arm on a substantiallyY vertical axis, for connecting the two arms in their various positions, and means to sec-ure the first-named means against movement with respect to one of the' arms.

6. .ln combination, a fixed structure and a beam-supporting means including vtwo arms one of which' is substantially horizontallyl shiftable,"and the other.. of which is pivotally movable on a substantially vertical axis` on said structure, one of said arms being also pivot-ally shift-able relatively to the other up and down, and means, pivotally connecting the'two arms in their various positions, and having its axis substantially vertical, for adjusting the up-anddown shiftable arm to different elevations.

7. In combination, a fixed structure and a beam-sup-porting meansv includingtwo arms 'one of which is substantially horizontally shiftable, and the other of which is pivot-ally movableon a substantially vertical. axis. on said structure, one of said arms being also pivotally shiftable relatively to the other up and down, andmeans pivotally connecting the two arms in their various positions and including a vertical screw arranged in one arm and a nut on the screw bearing against 'the latter arm, for adjusting the lip-.and-down shift-able arm to different elevations.
