WARP-BEAM FOR LOOMS.
SPECIFICATION forming part of Letters Patent No. 325,286, dated September 1, 1885.
Application filed October 15, 1884.
To add whom it may concern:
Be it known that I, ELISIIA SESSIONS BUR- LINGAME, of Central Falls, in the county of Providence, of the State of Rhode Island,
have invented a new and useful Improvement in W arpBeams for Looms; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure l is an isometric-a1 perspective view, and Fig. 2 a transverse section, of part of a warp'beam with my invention applied thereto, the nature of such invention being duly defined in the claims hereinafter presented.
1 Fig. 3 is a perspective view of the warp-beam with its two pulleys, two adjustable heads, and two adjustable aprons. A
The invention is not only to enable the beam-heads to be adjusted on the beam-body different distances apart, in order to adapt them to a warp of any desirable width to be wound on the beam, but to connect such warp with the beam. For this purpose I have each head movable on the beam-body lengthwise thereof, and provide the said head and beambody with mechanism for holding the head in any of its desirable posit-ions, so as to prevent it from either accidentally revolving on the beam-body or moving endwise thereon.
In the drawings the warp-beam body is shown at a, it being provided in the usual manner at each end with a journal,j, and a grooved pulley, 0. Between the two pulleys 0 there are to the beam and concentric therewith two circular heads, I), each of which is a wheel or disk made in two equal segments, provided at their chords with flanges b, for receiving screws 6', for connecting such segments together. Each screw 6 goes through a bolt, d, slotted lengthwise to receive it, and into a nut, e, which nut, when screwed against the bolt, serves to draw the two segments to ward each other and clamp the bolt to the flange against which it rests. To cooperate with each slotted bolt there is let into and fixed in the beam-body, flush with its outer periphery, a plate, f, provided with a series of holes ranging lengthwise of the beam, these holes being at equal distances apart, and each of a size to receive the bolt at its end. Such (No model.)
holes may be cylindrical; butI usually prefer to make them as short slots ranging transversel y of the beam.
On the bolt being moved so as to extend into any one of the said holes, and subsequently fixed in position by the screw and nut, such bolt and the plate f will operate to hold the head in position and to prevent it from turning on the beam-body independently thereof, when a person may take hold of the head and revolve it for the purpose of revolving the beam, as it is customary for weavers so to do.
The beam-body has two grooves, '0, made in it lengthwise at its periphery, they being 6 at a short distance apart and parallel to each other. Each groove is partly covered by two metallic strips, d, arranged at ashort distance apart and secured to the beam by screws. These strips run lengthwise of the beam. Be- 0 tween each pair of them, and extending into and out of their groove, is one of a pair of aprons, it, each of which at its inner end is hemmed to receive a rod, '5, having a width or diameter greater than the distance between the two metallic strips, which should be apart from each other a distancea little greater than the thickness of the apron. The rod and the strips serve to keep the apron in connection with the beam. The apron can beslid toward either of the heads. Thus each of the two aprons can be adjusted so as to have its outer edge close to or against the next adjacent head when the two heads may have been disposed at the distance apart such as may be required 8 5 for the warp to be attached to the aprons and wound with them on the beam. Any suitable mode of connecting the warp to the two aprons when adjusted may be employed.
For holding each head in position, as ex- 0 plained, on the beam, after such head may have been adjusted thereon, any other proper mechanism than that hereinbefore described for such purpose, and which may be considered a mechanical equivalent for it, may be 5 substituted.

2. The combination of the warp-beam body allel grooves c c and the strips d, arranged a, provided with the perforated plates f, fixed a short distance apart and partly covering on it, and with the heads 1), adjustable on it said grooves, in combination with the aprons longitudinally, and having bolts d to engage 7c 70, having at one end the rods ii, one resting 5 with such plates, as set forth, With the two in each groove 0 c, as set forth.
