TO ALL WHOM I'l MAY CONCERN:

Be itknown that I, FREDERICK W. HUPPELSIJE'RG, of No. 83 West Thirty-Seventh street, in the city, county, and State of New York, have invented a new and useful Improvement in Looms; and'I do hereby. declare that the following is a full, clear, and exact description thereof, reference being had tothe accompanying drawing` in which.-- Y I Figure I isan elevation in side view of a loom contaiisiingl improvement. Figure 2 is a front elevation. Figure?) is a plan view. Figure 4 is a 'diagram which shows theshape of the cloth Woven 'on the loom, and also thefmannerof placing or interweaving the weft in the warp'during the process ot` weaving. v

The object of this invention is to construct or produce a loom wh edges shall describe concentriccircles, so that when the ends of a piece of goods woven on such loom are united the said piece forms a hollow truncated cone, the projection ot` which resembles the diagram, lig. 4, said figure being a representation of a piece ofgoods produced or woven by means of my invention.

My invention Kalso embraces features which are applicable to ordinary looms. The frame of the loom is of any suitable construction or formto 4sustain the various parts, and I have shown only such parts of a loom as are necessary, in order to show and illustratemy,improvement. l i The letter D designates the lathe, whose swords are suspended from the upper part of thefrarne.V shuttle-race E is attached te the lathe as' usual. Said-shuttlelrace is so made as to 'eX-tend a greater distance beyond one side of the frame of the loom than it doesbeyond `the other side, for the purpose hereinafter explained.l The warp-threads are guided and separated, as sual,.by the reed in the lathe, and theyI are also gnidednnd separated as they enterthe loom by means of rods M, placed verticallyiritherear part of the frame of the loom.l VThe bobbin or spool-frame A, which holds the spoolsvof the warp, ,is arranged in a horizontal position instead of a vertical or inclined position. .Said spool-frame A is hinged to the frame of the loom or otherwise attached to it, so that it may be swung upwards against the loom when it is not in use, and. when said' frame A. is in its horizontal position it is supported therein by legs B, one or more resting ori the'iloor. lThe frame A is composed of numerous parallel strips or ribs PP, which have angular slots C C made across them at regular distances apartl to receive the ends or journals of the-spools orbobbins containing the warp, the ribs P being far enough apart to allow space hetween'them for the bobbins. v I

. By means of this arrangement VI am enabled to make the spool or bobbinsframe apart ofjthe loom itself, and to dispose the `spools in a horizontal position, and to dispense with the usual costly and cumbrous independent bobbin-frame non' employed for holding the warp-spools. The cloth woven upon the loom is taken up by meanslo a system of conical rollers or surfaces.V -exampleof my invention I einploy two conical take-up rollers J andK, whose axes are so arranged that the upper sideof theperiphery of the upper roller `J is level with the` cloth that is being woven,-` sequently inclined, as shown in the drawing. Tho'bearings of said upper roller are xed,` but roller K are movab1e, being formed in the inner ends else are provided with movable weights that cause th under surface of the upper roller. The lower roller lreceives its motion from frictional contact With the upper roller J, and the latter is rotatedlby means of a. train of geared wheels, I I I-I, which. aro-made 'to Yrotate by means of the vibration of the lathe through the' cords G G and levers F F',the latter lever I4" being weighted, "and being provided jwith a spring-paul that engages the teeth of a ratchet-wheel onthe lower gear H, on whose shaft thosaid lever F is placed, turning loosely thereon.V When the lever FQ is moved up'vvnrds by .the {fibration ofthe lathe inbeat'ingup,

on cord G is ich will automatically weave goods whose its'axis being conthose of the lower of levers L L, the outer ends ot which are madevheavy or relieved by the return 'or backward motion-,of .the lathe, theweight on said'lever F causes the "lever to fall so that the spring-pawlcan Vengage a fresh toothof said ratchet-wheel, the ratchet and gear lbeing Any other suitable .Take-up device means4 of ajncquard apparatus and N; but I have not shown the jacquard nor the leaves|` prevented from turning backwards-by means of a detent, Q, may be employed insteadr of the one here shown. leaves of harness .in connection with'a trap-board seen in iignl. vThe warp is operated by framek The A' e lower end to be pressed constantly upwards against thed the spring-pnwl turns the gear H a proportionaldistance, and when the 'sti-ain* Y novelty in th'm.
