QUILTING ATTACHMENT FOR SEWINGeMACHINES.

SPECIFICATION forming part of Letters Patent No. 271,920, dated February` 6, 1883.

Application nien July 13, ieee. (No model.)

r To all whom @t may concern:

Be it known that I, OWEN CAMPBELL POPE, of McMinnville, in the county of Warren and State of Tennessee, have invented certain new and useful Improvements in Quilting Attach` ments for Sewing-Machines and I do hereby Adeclare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it per-l tains to make and use the same.

My invention relates to an improvement in quilting attachments for sewing-machines, the object of the same being to provide a device of this character which will combinesimplicity and economy in construction with durability and eciency in use; and with these ends in view my inventionconsists in the parts `and combination of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure l is a plan view, showing my improvement secured to a sewing-machine. Fig. 2 is an end view of the carriage. one of the headblocks, and Fig. 4 shows the manner of securing the side tracks to the sewin g-machine table.

A represents a sewing-machine table, and B trackways, which latter are removably secured to the said table on opposite sides thereof. The trackways B, on opposite sides of the table, are of any suitable length, and are of width s'ucient to accommodate the carriage G, and the two tracks on the same side of thetahle are rigidly secured together by the cross-bars D. The inner cross-bars, or the bars which rest close up to the table A when the parts are. secured in position, are each provided with a step, a., which latter bears on the under side of the table. The inner endsof the two trackways are removably secured to the machine-table by the screw-clamps E, which lati ter bear respectively on th under side of the cross-bars and the top of the table and firmly clamps the parts together. The opposite or outer ends of the trackways are supported by the upright standards F. The standards F,

on the same side of the table, are connected together by the bars c, which firmly bind them together and hold them in their proper relative position. Each standard F is provided with an open oblong slot, d, in the upper end Fig. 3 is a detached view ofthereof, in which the opposite ends of the tie rods G rest. These tie-rods G pass transversel y through the tracks, and are each provided on one end with caplpieces and on the opposite'ends with screw-threads, on which thumb-screws Ei are secured. The projective ends of the tie-rods are placed in the oblong slot d, with the cap-pieces and thumbscrews outside of the standards. The trackway is then adjusted until it rests in a horizontalposition, when the trackway and standardsare rigidly secured together by the tightening thumb-nuts.

The carriage C consists ot' the end or head blocks, j', and the side rollers, I, which latter connect and hoid the head-blocks together.

Each head-block is provided near its opposite` ends with the depending wheels J, which latter are gaged to the tracks and on their upper surfaces with the open-inclined notches g, in which the bearing-spindles h ot' the rollers I rest and turn. The ends of the rollers I on the saine side of the carriage C are provided.

with the band-pulleys K, around which the belt L turns, and on the opposite side of the carriage one ArollerV is provided with a wormgear, M, and the other one with a ratchetwheel, M. The Worrn-gear M meshes with the worm N, the latter being journaled to one of 8o the head-blocks of the carriage G and operi ated by the crank O. As the crank O` is turned it also turns the worm-gear through'the intervention ofthe worm and operates the roller I, to which the worm-gear is secured. The roller I, with the gear-wheel thereon, being connected to the opposite roller by an endless bauch-it follows that as one roller turns the other also follows in the same direction. A dog, P, on the carriage (l engages the ratchet-wheel M' and prevents the roller I, to which it is secured, from turning backward and'unrolliug the quilt which has been wound thereon. The ends or sideof the quilt S can be secured directly to the rollers I, or to a suitable fabric secured to the said rollers.

The slack quilt is then wound on one roller,

and when the proper position has been reached the operation of stitching is begun, which is accomplished by the sewingmachine in the ordinary manner. The carriage, when in proper position, rests over the bed-plate of the sewingmachine, two of the bearings thereof being on IOO one side and two on the opposite side of the l is of few parts, is stron g,durable, and efficient table. The carriage-frameis ofsufcient length to accommodate any ordinary-sized quilt, and by simply movingthe carriage on the trackway the whole surface of the quilt is exposed to the action of the needle. v

As before stated, at the commencement of the stitching or quilting operation all of the quilt is wound on one roller I, excepting the portion resting between the two rollers. During the process of stitching the carriage can be fed forward on the trackway either auto-l matically, by suitable means, or by hand. After the entire width has been stitched the crank is turned and the quilt turned on the rollers until the proper point has been reached, when the stitching operation is again commenced. As the unstitched portion of the quilt is un- Wound from one roller the stitched portion is being wound on fthe opposite roller. When the entire quilt has been stitched crosswise it is removed from the rollers I and the sides thereof secured to the said rollers in the position formerly occupied by the ends of the said quilt. When-the parts are properly adjusted the stitching operation is again commenced and continued at proper intervals at right angles to the former stitches, which forms the blocks in the quilt.

If desired,suitable elastic straps can be secured at one end to the head or end blocks of the carriage, and b'e provided with hooks at their opposite ends for engagement with the sides of the quilt for the purpose of stretching the same whilelstitching.

In my improvement the quilt rests on the bed-plate ofthe sewing-machine, the parts being so adjusted to accomplish this end without the necessity of employing separate means for holding the quilt down in position.

Another important feature of my improvement is that the side trackways can be folded on or removed from the standards when not required for use, thereby enabling the parts to be packed in a small compass.

My improvement is simple in construction,

in use, and can be manufactured at a small initial cost.

It is evident that slight changes iu the construction and arrangement of the different parts might be resorted to without departing .from the spirit of my invention; and hence I would have it understood that I do not limit myself to the exact construction of parts shown and described, but consider myself at liberty to make such changes as come within the spirit and scope of my invention. f

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is l l. The combination, with a sewing-machine table, of two side trackways removably secured thereto by screw-clamps, the outer ends of the said trackways being adjustably secured to removable slotted standards, substantially as set forth.

2. The combination, with a sewing-machine table, of two side trackways provided at their inner ends with bearing-stops, screw -clamps for connecting the said table and trackways, tie-rodspassin g transversely through the outer ends of the trackways, and standards provided at their upper ends with open slots in which the said tie-rods rest, all of the above parts constructed,combined, and adapted to operate as described.

3. The combination, with trackways secured to a sewing-machine table, of a carriage consistin g of head-blocks provided with supportin g-wheels and furnished with open slots, and rollers removably secured Within the open slots and serving as the sides of the carriage, substantially as set forth.

In testimony whereoflhave signed this specification in the presence of two subscribing witnesses.

OWEN CAMPBELL POPE.
