GUIDE ATTACHMENT FOE SEWING-MACHINES.

Specification of Letters Patent.

Patented Nov. 9, 1915.

Application filed December 5, 1914. Serial No. 875,678.

To all whom it may concern Be it known that I, SERENA CARLTON, a citizen of the United States, residing at Blue Island, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Guide Attachments for Sewing-Machines, of which the following is a specification.

The attachment which is the subject matter of the present application for patent is designed for the purpose of guiding the hem of the material to obtain a straight line of stitches, and the invention has for its object to provide a simple and very eflicient device of this kind, and also one which can be readily applied, and which is adjustable according to the width of the hem. These objects are attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawing in which- Figure 1 is an elevation of a fragment of a sewing machine showing the application of the invention; Fig. 2 is a plan view of the device, and Figs. 3 and 4 are enlarged sections on the lines 33 and tt, respectively, of Fig. 2.

Referring specifically to the drawing, 5 denotes the sewing machine arm; 6, the needle bar, and? the presser foot. The bed or table of the machine is shown at 8. The invention is applicable to any ordinary sewing machine, and as no claim is made for the latter, a detailed description thereof is deemed unnecessary.

The guide attachment comprises a base member 9 carrying at one end an elongated cross strip along which the edge of the hem is guided. This cross strip comprises a horizontal bottom part 10 having at one of its longitudinal edges an upward bend 11 terminating in a forward bend 12 which overhangs the part 10. The hem is placed between the parts 10 and 12, and guided along the upstanding part 11. Intermediate the ends of the strip a tongue 13 is cut out of the same and bent rearward into a horizontal plane, which tongue engages the top of the base member 9.

The base member 9 is an elongated strip having a longitudinal slot 14. One end of the strip has a downwardly offset portion 15, and the opposite end of the strip has a similar ofiset 16. The last-mentioned end of the strip also has a lateral extension 17 on one side which is flush with the offset 16. In the part 17 are perforations 18 for a purpose to be presently described. To the offset 15 are pivoted, by means of a bolt 19, two curved arms 20 which are designed to embrace the sewing machine arm 5. The bolt 19 carries a wing nut 21 for locking the arms 20 after they have been placed on opposite sides of the arm 5 as shown in Fig. 2. Upon backing the wing nut the arms 20 are released and they may then be spread to take the arm 5 or to be disengaged therefrom. The arms 20 serve to hold one end of the member 9, the other end being held by passing a screw 22 through one of the perforations 17 into the bed or table 8.

The tongue 13 carries a bolt 23, the shank of which extends into the slot 1 1, and the head 2% of said bolt seating against the under side of the member 9. That part of the bolt shank which is in the slot 14; is squared, as indicated at 25, whereby the bolt is prevented from turning. On the upper end of the bolt is screwed a nut 26, which when it is backed, allows the guide strip 10 to be adjusted along the member 9, and upon screwing the nut down against the tongue 13, the guide strip is clamped to the member 9. The guide strip is thus adjustable toward and from the needle bar 6, so that it may be set for different widths of hems. The tongue 13 is formed by making two parallel slits in the part 10 and bending the material between said slits rearward, which leaves a recess 27 in said part 10, to accommodate the member 9. The offsets l5 and 16 space the slotted part of the member 9 a sufficient distance from the bed or table 8 so that the bolt head 24 clears the latter. The bolt may therefore be moved along the slot to effect the adjustment of the guide strip, without mar-ring or scratching the bed or table 8.

I claim:

1. A guide attachment for sewing machines comprising a longitudinally slotted base member, pivoted arms carried by one end of said member for embracing the sew ing machine arm, clamping means for said pivoted arms, means for securing the other end of the base member to the sewing machine table or bed, a transverse guide strip carried by the base member, a bolt carried by the guide strip and extending into the slot of the base member, and a clamping nut on the bolt.

2. A guide attachment for sewing machines comprising a longitudinally slotted base member, pivoted arms carried by one end of said member for embracing the sew- 5 ing machine arm, the other end of the base member having a perforated lateral extension, fastening means passing through the perforation of the extension into the sewing machine table or bed, a transverse guide 10 strip carried by the base member, a bolt carried by the guide strip and extending into theslot of the base member, a clamping nut on the bolt, and clamping means for the aforesaid pivoted arms.

In testimony whereof I affix my signature 15 in presence of two Witnesses.

' SERENA CARLTON.
