QUILTER.

Application filed September 11, 1926. Serial No. 134,878.

This invention relates to machines especially designed for quilting purposes, and aims to provide novel means whereby a quilting machiiie will be automatically 5 moved along its supporting track while the needle thereo'liis being operated to accomplish the quilting result.

A further object of the invention is to so support the machine on its track that the minimum amount of power on the part of the operator will be required in the operation of the machine to cause the machine to move longitudinally of the track on which it is supported.

\Vith the foregoing andother objeotsin view which will appear as the description proceeds, the invention resides in the combiuation and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed, with out departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is a perspective view illustrating a machine UOHSlDLIlCtBtl in accordance with the invention.

Figure 2 is a fragmental sectional View taken on line 2-2 of Figure 3.

Figure 3 is a sectional view taken on line 3-3 of Figure 2.

Figure 4- is a bottom plan view of the ma-v chine removed from its track.

Figure 5 is an enlarged detail view of the advancing mechanism.

Figure 6 is a detail view illustrating the manner of supporting the track.

Referring to the drawings in detail, the reference character 5 indicates the end rails of a quilting frame, and the reference char acter (5 indicates the side rails thereof, the end rails being provided with eye bolts 7 through which the hooks 8 pass. These hooks 8 are carried at the lower ends of the supporting cables 9 that have their upper ends secures against movement at 10.

The device forming the essence of the present invention embodies a. machine indicated generally by the reference character 11, which machine embodies the usual operating mechanism for operating the needle bar plishing the quilting result.

The. needle smpporting arm operat ng 12 that carries the needle for accom mechanism includes ashaft not. shown, and to which one end. of the arm 13 is secured, the connection between the arm 13 and shaft being in the form of a crank arm to cause the arm 13 to movein a vertical plane.

As clearly shown by Figure 5 of the drawings, the lower end of the arm 13 is curved where it has connection with the arm 14, through the medium of the bearing member 15, the arm 14 extending rearwardly from the shaft 16.

This shaft 16 is mounted for movement in the base of the machine and is provided with aclamping member 17 which in turn has an offset member 18 in which the shaft 19 is positioned, the shaft 19 providing a bearing for the arm 20 that carries the lug 21 at its free end. i

As shown, this lug 21 is tapered so that the same will fit between the teeth 22 of the bar 23 that secured to the bar 24 forming a part of the track. As clearly shown by the drawings, the track embodies bars 24 and 25 which are arranged in spaced relation with each other, so that all portions of the machine will. be adequately supported.

The base of the machine is secured to the carriage 26 that supports rollers 27 at it ends the rollers 27 operating over the bar 24 while at the outer end of the base is supported a roller 28 that moves over the bar 25, to the end that the machine will be supported in such a way that it may move freely longitudinally of the track or bars.

Arms 29 provide the supporting means for the track or bars 24 and 25, the same having inwardly extended portions 30 adapted to rest over the end bars 5 of the quilting frame, the end bars 5 being provided with suitable notches spaced apart distances equal to the distances between adjacent lines of stitching formed during the quilting operation.

Secured to the base and extending laterally therefrom is an arm 31 which is provided with a shaft 32 on which the pulley 33 operates, the pulley 33 having a hand grip 34: that may be grasped by the hand of the operator for rotating the pulley 33.

' Rotary movement of the pulley 33 is transmitted to the power wheel through the medium of the belt 36, to the end that the mechanism of the machine may be operated in the usual and well known manner.

From the foregoing it will be obvious that when the pulley 33 is operated to rotate the power wheel 35, the shaft 16 will be oscillated, moving the arm 20 and causing the lu 21 at the outer end thereof to move with oscillation ofthe shaft, with the result that as the arm is moved, the machine and its. carriage will be moved longitudinally of the bars 24 and 25 or supporting track, step by step, the distance of each notch with each oscillation of the shaft.

A lifting bar indicated at 37 is secured to the base of the machine, and affords means whereby the machine may he lifted in order to shift the machine to the right or left or properly position the machine for operation.

In the operation of the machine, the machine is moved longitudinally of its track and a line of stitching is made over the quilt being quilted. to the end of the track the machine is manually returned t '18 right endot the quilting frame, whereupon, the track is moved 7 along the end bars 5 of the quilting frame,

one notch, and the machine is again placed in operation to form another line oil stitchmg.

This operation is repeated until the quilt has been finally completed.

I claim 1. In a quilting machine, a quilting frame i iter the machine has passedembodying end rails and side rails, means for adjustably connectin the end rails and side rails, a track inclu ing parallel bars,

spaced apart, supporting arms to which the bars of the track are secured, said supporting arms having books at their upper ends positioned over the end. rails of the quilting frame, and adapted to he slid longitudinally of the end rails, a sewing machine embodying a base having rollers adapted to move over the track, and means for suspending the frame from an elevated supporting structure.
