QUILTING-MACHINE FRAME. I

Specification of Letters Patent. Patented June 13, 1%16.

Application filed October 1, 1915. Serial No. 53,629.

To all whom it may concern:

Be it known that 1, JOHN D. MANN, a citizen of the United States, residing at'Peterstown, in the county of Monroe and State of West Virginia, have invented certain new and useful Improvements in Quilting-Machine Frames, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to an improvement in quilting machine frames, more particularly in the type of quilting machine frames that are suspended and used in connection with a sewing or quilting machine.

The object of my invention is to provide a collapsible frame for quilting machines which is simple in structure, easily assembled and taken apart and cheaply manufactured.

Another object of my invention is the provision of an improved carrying structure having novel assembled parts and adjust able cl'iaracteristics.

Still further objects and advantages of my structure will be ascertained from the following description of the structure of my frame to whichreference is also made in the accompanying drawings, Figure 1 of which represents a front elevation of the frame in its suspended position. Fig. 2 of which represents a. side elevation of the frame in its suspended position. Figs. 3, 4;

and 5 show detail. views of the structure.

Referring to the drawings AA designate the two end or side bars of the frame. Extending transversely between these bars are located the rollers B on which the material to be quilted is'carried; the arrangement and structure of these rollers does not differ from that used in former devices of this character. One is placed at one end of the side bars which roller receives the upper and lower pieces of fabric after the same have been quilted, and two similar rollers are placed one at the other end of the side bars on which one is rolled a sheet of fabric forming one side of the material to be quilted, and the otherclosely alongside thereof from which is rolled a sheet of fabric forming the opposite. side of the material to be quilted, but with sufiicient space intervening for the passage of the batting or filling material. The ends of these roll ers are provided with suitable trunnions b, which rest in grooves 0;. These trunnions are formed with an enlarged head :19 having close engagement with the outside of the side bars. nions rest are lined with suitable bushing metal a, which prevents wearing of the grooves. V

Springs 1 are associated with the openings of the groove which insures the trunnions on the rollers being held in the grooves without danger of slipping or working therefrom. I provide flanges or circular plates d at the ends of the rollers and having close association with the inner surface of the side bars, these plates have a series of perforations e arranged circumferentially thereof into which enter locking means 6 suitably secured to the side bars.

The advantage of having the heads of the trunnions and the flanges closely associated with the outer and inner surfaces of the side bars, is that there is the same dis tance between the heads of the trunnions and the flanges as the width of the side bars, and the close fit of the same holds the side bars rigid and prevents wearing and twisting.

Mounted on the side bars are uprights C provided at their ends adjacent the side bars with U shaped 'yokes g which embrace the side bars and allow for the longitudinal adjustment of the uprights on the bars whereby the frame may be kept on an operative plane regardless of the amount of material on either of the rollers. Suitable locking means for the uprights in their adjusted position are used, conveniently a longitudinal series of perforations h are formed in the side bars A and pins j are employed which are capable of being inserted in any of said perforations whereby the uprights C are locked against movement on the side bars. Besides being adjustable so as to keep the frame in relatively the same plane as the amount of material increases or decreases on the rollers, these uprights, together with the horizontal cross bar D, hereinafter described, serve other purposes namely, they hold the side bars A properly and rigidly spaced apart. A distinct advantage is in this as when any one or all of the rollers are withdrawn to receive additional material the side bars will remain in the same or practically the same position as when the rollers were in position on the frame, and therefore,

the collapse of the frame when the rollers are withdrawn is guarded against.

Suitably mounted on the uprights C is the The grooves in which the trun- I cross bar D of practically the same construction. as J the side bars, provided With ment by pins on insertiblein perforations n in the uprights. The object of the adjustment ofthis crossbar is that the frame can be raised'and loweredto approximately any position with respect tothe quilting or sewingmacliine.

The cross bar -D has mounted thereon pref erably an eye 0 to which is attached the suspending means of the frame. lhis suspends ing means consists, conveniently of a traveling block 79 mounted on Wires attached to the Walls of the room or place where the frame is to be used. By this means the movement of the Whole frame along the Wire is effected. V

In operation When the amount ofmaterial increases on the receiving roller the frame has a tendency to tilt, When this tilting is apparent to the operator it is merely necessary to remove the pins from the perforations wherein they are l0cated,,slide the uprightstoward the other end of the side bars until the frame assumes an operative or normal horizontal position. The uprights are then looked in their adjusted position by inserting the pins in the perforations that have the closest proximity to the yolres at tached to the uprights. I I

When any of the rollers are Withdrawn it will be apparent that the side bars will be held in their normal position by the rigidity of the uprightsand cross bar.

When during the quilting operation it is desirous to raise or lower the frame With relation to the quilting machine it is merely necessaryto remove the pins from their location in the perforations in the uprights, which allows the cross bar to be vertically adjusted on the uprights Where it may be the pins in the perforations having the closbar. I

' It will be readily seen that minor changes may be made in the construction of myquilting machine frame Without departing from the scope or spirit of my invention.

What I claim is:

1. In a quilting machine frame, the combination with parallel side bars having inclined trunnion receiving grooves in their upper faces at opposite ends, rollers having trunnions fitted in said grooves, springs overhanging the grooves, for normally retaining the trunnions in place, upright supports intermediate the ends of the bars, means for adjustably positioning the supports at different points on the sidebars and for retaining the same in said adjusted position, a cross bar connecting the supports and a flexible support connected centrally to the cross bar.

2. In a quilting machine framethe combination With side bars having trunnion receiving obliquely arranged metal lined gage the side of the side bars, With movable 'Ineans overlapping the grooves for retaining the rollers in place, adjustable uprights secured to the side bars intermechate their ends, securing pins-for maintaining the up rights in difierent positions of adjustments on the side bars, a rigld connecting bar beest proximity to the yokes above the cross grooves at opposite ends, rollers having tween the upper ends of the uprights, and a a flexible support connected to the connecting bar. w

In testimony whereof I hereunto affix my signature in the presence of two Witnesses.
