2 Claims. 1
This invention relates to attachments for sewing machines.
An object of this inventionis to provide an attachment for sewing machines which comprises a guide for sewing seams or heme of selected widths.
Another object of this invention is to provide a guide attachment which can be mounted on the presser foot bar for movement with the bar so that the guide may be raised to inoperative position with raising of the presser foot, and will be lowered to operative position with lowering of the presser foot. The device herein disclosed embodies a horizontal combined gauge and support for the guide with a connector for the shank of the guide which will permit the quick adjustment of the guide.
A further object of this invention is to pro vide a guide attachment of this kind which can be mounted on sewing machines of different makes without alteration in the machine or the attachment.
With the above and other objects in View, my invention consists in the arrangement, combi nation and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.
In the drawings,
Figure 1 is a detail front elevation of a sewing guide attachment constructed according to an embodiment of this invention, mounted on the presser foot bar of a conventional sewing machine,
Figure 2 is a sectional View taken on the line 2-2 of Figure 1,

Figure 6 is a fragmentary sectional view taken on the line B--5 of Figure 2,
Figure 7 is a fragmentary sectional View taken on the line 7-1 of Figure 3,
Figure 8 is a detail front elevation of a modified form of this invention,
Figure 9 is a sectional view taken on the line 9-9 of Figure 8,
Figure 10 is a fragmentary sectional view taken on the line Ill-ll! of Figure 9.
Referring to the drawings and first to Figures 1 to 7 inclusive, the numeral I5 designates generally a conventional sewing machine head which has extending downwardly therefrom a presser foot supporting bar or shaft IE on which is mounted a presser foot H. The construction of the sewing machine head, including the presser foot and supporting bar, is conventional.
In order to provide a means whereby in stitching a hem or the like the width of the hem can be accurately gauged, I have provided a guide bar or foot 18 which is adapted to be positioned in a selected adjusted position laterally of the presser foot ll for engagement with an edge of a hem I 9. The guide foot or bar I8 includes a right angularly disposed shank 20 which is secured to a horizontally disposed bar 2! carried by a vertically adjustable bar generally designated as 22.
The bar 22 includes a vertical portion 23 terminating at its upper end in a horizontal and rearwardly extending portion 2 1, and the latter has extending vertically and upwardly from the rear end thereof a shank 25, having a flattened forward face 28. The shank 25 engages in a slot or opening 2? which is formed in the rear side of an adjustable slide block 23. A set screw 29 is threaded in the rear side of the slide block 28 and is adapted to bear against the shank 25 with the. flat side 26 of the shank 25 bearing against the flat inner side 3! of the slot 27.
The slide block 28 is formed with an opening 31 extending horizontally therethrough, within which a supporting bar 32 engages. A set screw 33 is threaded into the upper side of the slide block 28, and a wear plate 34 is interposed between the lower or inner end of the set screw 33 and the upper edge of the supporting bar 32 so that when the set screw 33 is tightened the set screw will not mar the upper edge of the supporting bar 32.
The supporting bar 32 is formed on the forward side thereof with graduations 35, by means of which the guide foot or bar 58 may be finely adjusted with respect to the needle of the sewing machine. The bar 32 is provided at its outer end with a stud 36 which engages through a supporting body 31. The body 31 is formed with an opening 38 through which the presser foot shaft or bar 16 is adapted to engage, and as shown in Figure 2, the body 37 is split as indicated at 39 so as to form an integral clamping member 4E! which is tightly secured on the bar or shaft 16 by means of a clamping screw or bolt 41..
The stud 36 is rotatable through the body 31 and has secured to the outer end thereof a block 42 which is of substantially square shape and is formed with one rounded corner 43. The block 42 provides an adjusting means whereby the bar 32 may be rotated through an arc of 90 from a position with the guide member engaging the work on the stitching table, to a position substantially horizontally and rearwardly disposed, as shown in dotted lines in Figure 3. A flat spring 44 bears against the block 52, as shown in Figure 5, and is secured in the slot 15 formed in the body 31 by means of a fastening member 40.
Referring now to Figures 8, 9 and 10, there is disclosed a modified form of this invention. A work guide member 13a which is similar to the guide member 58 and is carried by a supporting member 2% is vertically adjustable in a slide block 41. The slide block 41 is formed with an opening d8 through which a threaded supporting bar 49 is adapted to loosely engage. The bar 39 has threaded thereon a nut 50, and the latter is swivelly mounted in an opening 5! formed in the block 451, by means of a slotted plate 52 which is 58- cured by fastening means 53 in a slot 55 formed in the block Q1. The nut 59 is formed with an annular groove 55 within which the slotted retaining plate 52 is adapted to loosely engage.
The supporting member 69 is secured to a body 37a which is similar in every detail to the body i, and is angularly adjustable relative to the body 31a in the same manner as the bar 33 The block 5'? has a set screw 53 threaded thereinto, which bears against a wear plate 51' engaging a flattened longitudinally extending surface 53 formed on the threaded bar 39.
The block A? is formed with an opening 59 through'which the shank a of the supporting member 22a is adapted to extend and to be vertically adjusted, by means of a set screw 29a. In order to provide a means whereby the guide member 18a may be accurately adjusted with respect to the presser foot i'ia, and the needle of the sewing machine, I have provided a gauge bar 653 formed with graduatio-ns 01. The gauge bar 50 is disposed in offset parallel relation with respect to the supporting member 39 and is provided at the opposite ends thereof with right angular extensions 62 which are secured by fastening means .63 to the flat side 58 of the supporting member A pointer is formed as an extension of retaining plate 52 and engages over the upper side of the gauge bar 08.
In the use and operation of this device, the body 31 is secured in vertically adjusted position on the presser foot bar .or shaft it so that when the supporting member 22 is inoperative position with the guide 13 lowermost, the guide it will be disposed in at least slightly contacting relation with respect to an edge of the work. The work is guided through the sewing machine in the normal manner, with an edge of the Work engaging the guide member iii, as shown at iii in Figure 1. The guide member 18 may be quickly swung to an inoperative position by merely pushing the supporting member 22 rearwardly and at this time the supporting member 22 will be disposed in the dotted line positionshown in Figure 3, being held in this position by means of the spring at. The attachment shown in Figures 8 to 10 operates in the same manner as that shown in Figures 1 to 7, with the exception that the slide block til is more finely adjusted by means of the nut The set screw 29 provides a lock for the slide block 23, whereas the set screw 56 provides a lock for the slide block M.
The attachment hereinbefore described can be mounted on sewing machines of conventional construction without changing the details of construction of the sewing machine and can be readily removed by removing the presser foot I! and raising the supporting shaft 10.
I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims.
