To all whom it may concern/. v

' Be it known that I, WlLLrAMlNlLsoiv, a citizen of the United States, residingat Boston, in thecounty of Sufiolk and State of Massachusetts, have invented certain new and useful Improvements in Work-Guiding Devices; and I do hereby declare the follow-. ing to 'be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains'to make and use the same.

This invention relates to improvements in work-guiding attachments for sewing-machines.

In the o eration of sewing-machines which are a apted for erforming work of various characters suc l, for instance,- as WaX- thread sewin machines which are adapted for sewing harness, hand-bags, and various'kinds of leather oodsit is neces-, sary inv adapting such mac ines to the different characters of work performed to use various work-guiding devices or attachments for uiding the materials operated upon.

T 1e present invention relates to improvements in the construction of such attachments; and one object of the invention is to produce means for mounting and securingguiding devices upon a sewing-machine which will permit the convenient adjustment of such devices and which may be used in 1 connection witha variety of different devices.

Another object is to produce an improved edge-gage attachment for sewing-mach nes. The invention consists in the work-guidmg attachment hereinafter described as defined in the claim.

In the drawings, Figure 1 is a side eleva tion of a work-guiding attachment embod ing the present invention, together with tlie adjacent parts of a sewing-machine in connection vwith which it is used. Fig. 2 is a plan view of the attachment. 4 front elevation of the upper portion of the attachmehtwith the edgeage removed. Fig. 4 is a vertical section of t p e same part. Fig.

7 5 is a horizontal section showing in detail the stop-collar and cooperating parts.

Theillustrated embodiment of the invention is shown in the, drawings as attached to the well-known Campbell wax-thread sewin'g-machine, which need not be particularly described. The awl 1 presser-fcot 2, and work-table 3 are all of familiar forms.

Fig. 3 is a- The work-guiding attachment comprises a vertical post 4, secured to the frame of the machine and provided with a vertical socket for the reception of a round stem 5, which may be raised or lowered in the post 4 or proper position maybe 'securedbya thumbscrew 6, which is threaded into lugs 7 in the upper end of the post 4 and operates to draw purpose. em 5 carries on its upper end a horizontal bar 8, upon which is slidingly mounted a block 9, which may be secured in adjusted position on the bar 8 by a set-screw 10. The block 9 carries the workuiding devices, which in the illustrated embodiment of the invention are two edgegages, of which one (marked 11) is formed integral-with the block 9', while the other, 12," is provided with an arm 13, pivoted upon the set-screw 10. The arm 13 is provided with a socket concentric with the set-screw, within which is located a compression-spring 14, and the lower face ofthe arm has a slight depres sionengaged when the gage is in working position by the rounded upper end of a pin 15, fixed in the block. 9. By this construction the edgeage 12 is held normally in Working position, Imt may be easily swung away by the operator against the resistance. of the spring '14 and pm 15 .when it is necessary to temporarilydiscontinue its useas, for example, in performing certain operations on harness where the .pi'e'ces being sewed are of irregular form.

The edge-gage 1 1 is provided foruse where it-is necessary to use a narrower gage than the gpgclZ. B adjustin the block 9 along the at 8 the from the needle may be varied so as to adjust the distance between the seam and the edge of the work. 'The edge-gage 11 is not pivotally mountedupon the block 9, like the edge-gage 12, but provision is madefor swing: ing the attachmentas a whole, with the exany other work-guiding device which may be en stituted therefor may be swung into and out of working position during the operation of the-machine. To this end the stem 5 is provided with a stop-collar 16 which is s lit and provided with a screw 17, by whic itmay be clamped upon stem 5. This collar determines the height of the stem 5 in the post 4, so that when the thumb-screw 6 is the lugs-to'gleitlher, the post being split for this e st istance o either edge-gage turned therein and which when adjusted to ception of the post 4, so that the gage 11 or provided with a downwardly-extendingstop vided loosened the stem 5 and parts carried therebymay be swung in the post without changin their vertical position.

11 order that the work-guiding device when swung back to working position may always swing to the same point without attention on the partof the operator, the stop-collar 16-is 18, which engages a corresponding lug 19 on the post 4. By loosening the stop-collar 16 and turning it upon the stem 5 the parts may be adjusted so that they will stop at the proper position, and until this adjustment is changed they will always return to the same point. The stem 5 and parts carried thereby may also be entirely removed from the post 4 to substitute another attachment, and when replaced will return to proper position without readjustment.

The stem 5, bar 8, and 'sto -collar 16, form acarrier which may be use for various workuiding devices, the adjustments pro 1n these parts being useful in connection with the various devices, and though the Invention is described particularly as used in connectlon with edge-gages it will be understood that except in so far as the claim is specifically limited to such construction it is intended to cover the use of the form of carrier shown in connection with various work-guiding devices.

Having now described the invention, what is claimed is- A Work-guiding attachment for sewingmachines having, in combination with the base of the machine, an upwardly-extending support provided with a vertical socket and means for clamping a stem therein, a stem removably j ournaled injthe support and carrying a work-guide, a collar fixed but vertically and rotatably adjustable on the stem and engaging the top of the support, and cooperating stops on the collar and the support for limiting in one direction, the rotation of the stem in the socket, substantially as described. In testimony whereof I aflix my signature in presence oftwo witnesses.

WILLIAM WILSON.
